Index at Acceptance:-Class 20 ( 2), El. International Classification:-E 21 d. COMPLETE SPECIFICATION Connectioii for Lagging Irons for Use in Mines. I, JOSEF BRAN of German nationality of 39, Sofienstrasse, Duisburg-Hamborn, Germany, do hereby declare the invention for which I pray that a patent may be granted to me; and the method by which it is to be performed to be particularly described in and by the following statement:- This invention relates to lagging irons as used in the lagging of

underground mine workings and which are of the kind that is advanced cantilever-fashion with the object of providing a coal face free from pit props In particular the invention relates to the connecting means between lagging irons by which they are locked together. Numerous constructions of such lagging iron connections are known, and those generally used in practice are formed by having one end of the lagging iron fork-shaped and the other end in the shape of a tongue adapted to be inserted into the fork, the lagging irons being articulated to one another by means of a pin passing through the prongs of a fork and the tongue to connect two irons together, and are clamped with respect to one another by means of a wedge driven in between the end of the tongue and a counter-face on the forked piece in a position capable of mutual angular deflection within certain limits by driving in the wedge more or less deeply, the lagging iron adjacent the coal face being thus lifted or lowered This invention has the object of providing improvements in lagging iron connections of this kind. Hitherto, the mounting of a lagging iron was generally effected so that the forked part was directed towards the coal face The difficulty then arises that the lagging iron cannot at once be articulated in a suspended position to a previously fitted lagging iron by means of the pivot pin, since the end of the tongue would then, in the downwardly hanging position of the lagging iron, project over the upper edge of the connecting parts of the previous iron and this projecting part would generally abut lPrice 3 s 6 d l on the mine roof. In order to overcome this difficulty, it has been proposed that the lagging iron to be inserted shall not be immediately connected permanently to the lagging iron previously 50 fitted but shall be provisionally suspended thereon firstly by means of a -thin auxiliary bolt or pin which penetrates through a bore in the prongs of the fork part and a bore in the tongue in front of the pivot pin proper in such 55 a manner that the arcuate rocking circle of the tip of the tongue lies within the profile of the lagging iron previously fitted Only after the lagging iron has been tilted up about this auxiliary pin, is the pivot pin proper driven in 60 and then the connection is clamped or blocked by means of the wedge, the auxiliary pin being afterwards removed. These known connecting means have the great disadvantage that the pulling out of the 65 auxiliary pin is frequently forgotten, with the consequence that it is sheared off or at least bent when the inserted lagging iron is exposed to load. According to the invention there is provided 70 connecting means for lagging irons for underground mining, which means is formed by a tongue of one lagging iron extending into a fork end of the other

lagging iron and by a pivot pin penetrating through bores in the 75 prongs of the fork and the tongue, the connection being capable of being rendered rigid by means of a clamping wedge passing through the prongs of the fork and acting on the end face of the tongue and being capable of angu 80 larly deflecting the two lagging irons to a desired degree with respect to one another, characterised in that the lagging irons are fixed with the tongue pointing in a direction towards a coal or other working face, the prongs of the 85 fork being extended so that the said tongue extends in such a manner that the distance from the axis of the pin to the free end of the fork part is not greater than half the height of the lagging iron profile or cross-section 90 He The suspension of the inserted lagging iron can be effected regardless of the length of the tongue and-by immediate connection of the forked part to the tongue of the previously fixed lagging iron by means of the pivot pin itself Thus the tongue of the connecting means can be much longer than hitherto thus giving the advantage of a long lever arm. In a further development of the invention the effectiveness of the lever arm is further improved by a'new disposition of the clamping wedge so that it acts on the counter face of the tongue always in that direction in which the full force of the wedge is utilised, whereas in the known arrangements one component only of the wedge force is effective for clamping. For this purpose, the bores, receiving the wedge, formed in the prongs of the fork, are shaped in such manner that the wedge is guided in the corresponding slanting position and the front face of the tongue is made slightly concave in such a manner that the wedge acts always at right angles to the tangent of this concave surface, in the most advantageous position The new shaping of the bores makes it possible to accommodate the clamping wedge in a very simple manner so that it need not be removed completely for the purpose of releasing the connection after the newly fixed lagging iron has been supported by a prop, or for the purpose of using the lagging iron in the position turned through 1800 round its axis. An embodiment of the invention will now be described with reference to the accbmpanying drawing, in which:Figure 1 shows the lagging iron connection in lateral elevation. Figure 2 shows a horizontal section along the line A-B of Figure 1, and Figure 3 shows a section along the line C-D of Figure 1. In the drawing the lagging iron previously fixed and already supported by one or more pit props is denoted a, the tongue b of which extends towards the coal face, and the lagging ironi to be fixed cantilever fashion is denoted by c, which ends in a forked portion d facing away from the coal face -The two lagging irons are connected to one another

by means of a pivot pin e passing through bores in the prongs d of the fork and in the tongue b The same is secured in a manner known per se, against being completely detached from the lock by a safety projection f fixed to one prong of the fork, which is slidable in groove g of the pin. The wedge h, which clamps the two lagging irons with respect to one another in the stretched or more or less angularly deflected position, is guided in a heart-shaped recess i in the prongs of the fork, and acts on the abutment face k of the tongue b, which as will be seen particularly from Figure 1 is slightly concave The heart-shaped formation of the recess i makes it possible to insert the wedge at will in a position sloping obliquely downward or obliquely upward in such a manner that by abutting on both sides of the guide formed thereby, it acts in one position on the lower range and in the other position on the upper range of the concave contact face of the 7,0 tongue The wedge has an end nose 1 known in itself, which secures it against the possibility of complete separation from the forked piece, and is formed in such a manner that when being pulled out right up to the limit 75 defined by the nose-l abutting on the fork, play is available in the heart-shaped recess, which peanits the rocking of the wedge from the lower into the upper inclined position or vice versa for the purpose of abolishing the rigidity 80 of the connection after the new lagging iron has been propped by a pit prop or for the purpose of establishing a turned position. As will be seen the abutment face of the wedge formed by the end of the tongue b lies 85 at a comparatively large distance from the pivot pin Hence a lever arm of corresponding length, such as is not available with the known embodiments -for the reasons pointed out hereinbefore, allows the optimum engagement 90 conceivable of the wedge force being attained owing to the concave formation of the abutment face in conjunction with the oblique positioning of the wedge.

Apparatus for dispensing webs from toilet and other rolls


I, FREDERICK PERCIVAL AYERS, a British Subject, of 4 Rossdale Drive, Kingsbury, London, N W 9, do hereby declare the invention, for which I pray that a patent may be granted to me, and the method by which it is to be performed, to be particularly described in and by the following statement:- This invention has reference to apparatus for dispensing paper, tissue and other webs from rolls or spools thereof, particularly toilet rolls, and for preventing pilfering, of the kind provided with a back plate, side wings and slideways in said wings within which the axle of the roll or the like rides and is rotatably mounted, said slideways having entrance and exit openings situated at distances from the back plate equal to at least the radius of the full and not much more than the radius of the spent rolls respectively, a detent or catch being provided at the entrance opening permitting the entry of the roll axle but preventing its withdrawal In conveniences, hotels, works and 3 other public or semi-public places, where there is a risk of pilfering, such an apparatus enables a roll which is in use to be imprisoned against extraction, and renders the core incapable of removal until its web has been practically exhausted The main object of this invention is to provide, in such an apparatus, means for storing a reserve roll or rolls so as to be similarly imprisoned and capable of being brought into action when the roll in use is exhausted. Usually, the replacement of an exhausted roll, should it be necessary throughout the day or other period fixed for regular replenishment, is catered for by leaving a spare roll handy alongside the one in use, and it frequently happens that not only is the spare roll missing but also the one in use Accordingly the invention provides an apparatus wherein when the rolls are loaded lPrice 3 s 6 d l on their respective axles in the container, all are imprisoned against extraction. According to the invention, in an apparatus of the kind hereinbefore set forth there is provided top slideways for holding and trapping the roll in use, substantially vertical slideways in communication with

such top slideways and adapted to contain one or more spare rolls to be held in reserve, the storage slideways being provided at their lower parts with the entrance openings having a non-return means to prevent withdrawal of an inserted roll A reserve roll is thus movable to the in-use position in the top slideways after the removal, when spent, of the previous roll in use. Thus a roll may be mounted on an axle and loaded into the container by pushing the axle up the vertical slideways from their entrance openings, past the catch, and thence it is imprisoned in the slideways On reachthe tops of the slideways the position of the exit openings prevents further upward movement because the diameter of the roll will not allow travel of the axle towards the said exit openings, e g along the lateral branches It is only when the said diameter has been sufficiently reduced, by exhausting the web, until practically only the usual tubular cardboard or other core remains, that the axle can be moved towards the back structure of the container to allow the axle with the exhausted core to align with the exit openings and be removed The depth of the container is determined by the number of reserve rolls it is desired to load into the container underneath the one in use. In such a case when the upper one has been exhausted and the axle and core removed, a reserve roll may be moved up in its place. In order that the said invention may be readily understood some embodiments thereof will be described with the aid of the accompanying drawings, wherein:M Pce 25 p 785,064 PATENT SPECFICATION Date of filing Complete Specification: Feb 29, 1956.

Apparatus for Dispensing Webs from Toilet and other Rolls. -1 785,064 Figure 1 is a vertical section of one embodiment on the line I-I of Figure 2. Figure 2 is a front view of Figure 1. Figure 3 is a plan of Figure 1. a Figures 4, 5 and 6 are inner face views of three alternative forms of side plate. Referring to Figures 1, 2 and 3 the apparatus comprises a container made up from a back member in the form of a plate 1 for attachment to a wall or other fixture, and a pair of parallel side walls 2, 2 extending fixedly therefrom, and a spacing tie rod 3 spanning the front opening between the side walls The top and bottom and the front between the side walls are open Each side wall is formed on its inner

surface with a vertical slideway 4, preferably made by casting parallel ribs, and the slideway is branched outwardly at the bottom at 5 to open at the edge of the wall and constitute a feed opening 6 A pair of axles 12 are mounted within the container between the side walls 2 with their ends resting respectively in the slideways. Near the bottom of each slideway a side thereof (i e the rib in the present example), is interrupted to form a pocket 7 for a loose gravity catch 8 This is a flat gravity disc having a diameter larger than the width of the slideway so that normally it rests on the base of the pocket with more than one half extending into the slideway and the remainder housed in the pocket The pocket is made with a slightly recessed base part 9 with an inclined slot 10 covered by a plate 11 The height of the slot opening which leads into the slideway through which the disc 8 protrudes is larger than the diameter of the disc and consequently when the end of the axle 12 is pressed from underneath against the catch disc 8 the latter recedes into the pocket allowing the axle to pass whereupon the disc falls back into the slideway into the position shown in Figure 1 constituting an obstruction for any downward return movement of the axle. At the top of each wall 2 the slideway 4 is formed with a tee-shape at 13 blocking the passage of the axle against direct upward removal This shape forms lateral branches 14 and 15 which are respectively directed backwardly and forwardly The latter branch 15 has a depression 16 into which the axle can be lodged during use of the roll The backwardly directed branch 14 leads to a discharge slot 17 opening upwardly through which the axle can be removed from the container when the diameter of the roll has been reduced sufficiently to enable what is left of the latter to be pushed back against the rear wall of the container to bring the axle in register with the discharge slot In the drawings the circles 18 represent the outer periphery of ( 35 a full roll -and the -circles 19 the periphery of a core on which the web is rolled It will be seen in Figure 1 that the distance of the slideway 4 from the back plate 1 is sufficient to enable a full roll to be carried in the slideway, but the distance of the slot 70 17 is such that the axle 12 cannot be brought into alignment until the diameter of the roll has been reduced to substantially that of the core 19. In the modifications seen in Figures 4, 5 75 and 6 the slideway 4 a is inclined slightly forward towards the top and a single lateral branch 14 a formed which extends rearwardly In Figure 4 the branch is horizontal, in Figure 5 it extends backwardly and up 80 wardly, and in Figure 6 it is disposed in a downwardly inclined direction towards the back In these cases the axle 12, when it reaches the top of the slideway 4 a is brought into the lateral branch 14 a from which 85 position the web can be used A pocket 16 a equivalent to the pocket 16

in Figure 1 is employed in the Figure 4 construction but in the other designs no depression is employed apart from that caused by the inclina 90 tion of the branch 14 a. The width of the slideways is sufficient to accommodate the end of the axle 12 which may have a diameter to fit snugly within the usual cardboard core 19 of a toilet roll The 95 ends of the axles which fit the slideways may have the full diameter engaging in the slideways 4 or alternatively the latter may be narrow so as to take a pintle extending from the end of the axle In the form illustrated 100 the axle is of narrow diameter throughout its length and fitted with discs 12 a to fit the core. In the embodiments shown the height of the side plates is sufficient to accommodate 105 two rolls, the top one being in use as indicated by the hanging web 18 a, and the lower one held in reserve An extra gravity or equivalent catch may be located in the length of each slideway higher than the one 110 near the bottom, so as to prevent the roll which is in use falling down on top of the reserve roll The back plate 1 is provided with apertures, such as those shown in Figure 2, in 115 such positions that the securing screws or the like passing through them are inaccessible after the rolls have been loaded into the apparatus, thus preventing pilfering of the apparatus 120

Improvements in or relating to cigarette cases


PATENT SPECIFICATION )e Date of filing Complete Specification: Jan 31, 1956. Application Date: April 12, 1955 No 10561155. / Complete Specification Published: Oct 23, 1957. Index at Acceptance:-Class 18, A 2 G. international Classification:-B 65 d. COMPLETE SPECIFICATION. Improvements in or relating to Cigarette Cases. I, Ric HARD FI Tz POWER, a British Subject, of 18 Chesterford Gardens, Hampstead, London, N W 3, do hereby declare the invention for which I pray that a patent may be granted to me, and the method by which it is to be performed, to be particularly described in and by the following statement: This invention relates to cigarette cases of the kind including panels hinged together along one side edge and provided at the opposite edge with an inwardly movable catch device. A main object of the present invention is to provide such cigarette cases with means for raising the outer ends of cigarettes in the case so as to make the outer ends readily accessible to the user of the case, and a further object is to provide means for selectively segregating the ends of a few cigarettes from the rest of the cigarettes in the case so that the segregated few are readily accessible. A cigarette case including panels hinged together along one side edge and provided at the opposite edge with an inwardly movable catch device is, in accordance with the invention, characterised by means for raising the outer ends of cigarettes in the case so as to make the outer ends readily accessible to the user of the case, such means

being disposed in relation to the catch device so as to be actuated as a result of operating the catch device. In operating the raising means the cigarettes are tilted about their inner ends so that they are raised for substantially their full length from the panel in which they are located and which comprises the catch of the case. A cigarette case constructed according to the invention is preferably characterised by a plate adapted to lie on the panel carrying the catch and under the outer ends of the lPrice 3 s 6 d l cigarettes to be raised, the outer edge of the plate being slightly outside the outer ends of the cigarettes, and the inner edge disposed so that when it is raised from the panel the cigarettes are tilted about their inner ends, and means for tilting the plate comprising an inverted Vee shaped element the inner limb of which is integral with the plate and rises therefrom to an axis member for the Vee element and extends thereover to form the outer limb of the Vee, which latter limb is directed downwardly from the axis member into proximity with the catch, so that as the catch is pressed inwardly to free the panels of the case to open the case the Vee element is rocked about the axis member and raises the outer ends of the cigarettes overlying the plate. In on practical embodiment of the invention the catch member is inwardly slidable and is normally pressed outwardly by a linear spring overlying the catch and secured to the free edge of the respective panel, the linear spring and catch also lying against the outer limb of the Vee shaped element so that operation of the catch causes the spring to transmit the effort to the said outer limb and thereby tilt the plate. In order that the invention may be more clearly understood preferred embodiments thereof will now be described by way of example with reference to the drawings accompanying the Provisional Specification in which:Fig 1 is a plan view of a case panel which carries the catch of the case and in which is located a plate for raising the outer ends of cigarettes in accordance with the invention; and Fig 2 is a sectional elevation taken on the lines II-II of Fig 1, showing the manner of hinging the plate. In the drawings like numerals designate the same parts. 785,066 65. 785,066 Referring to the drawings, the case comprises two panels 1 and 2 which are hinged together as indicated at 3, along the line parallel to the sides of the panels, and the. S free edge of the panel 2 opposite to the edge with the hinge is provided with an inwardly moving catch device 4 operated in usual manner by a thumb piece 5, the catch being inwardly slidable through a

slot made in the free edge of the panel 2 and being normally forced into the open position for the case by a spring 6, the free ends of which are secured by interlugs, not shown, in known manner emanating from the free edge of the panel. In accordance with the invention there is disposed on the panel 2 a plate 7 the outer edge 8 of which is slightly outside the outer ends of the cigarettes of which several are shown and indicated by the reference C, overlying the plate The outer edge of the plate is extended to form an inner limb 9 to an integral inverted Vee shaped element generally indicated at 10, the angle of which is seated on a longitudinal member 11 which is secured by two short arms 12, to the free edge of the panel 2, thus the Vee shaped element 10 can be rocked about the axis member 11 The complemental limb of the Vee shaped element is indicated at 13 and this outer limb of the element is, as clearly shown in Fig 2, directed downwardly from the axis 11 into proximity with the inner edge of the catch 4 and the linear spring 6 lies against the outer arm 13 of the Vee shaped element 10. Accordingly, when the catch is thumbpressed inwardly of the case to open the latter, the Vee shaped element is rocked on the axis 11, by the catch and spring being forced against arm 13, thus raising the plate 7 as shown in chain lines in Fig 2, the cigarettes C thus being tilted about their inner ends into a position, such that the outer ends of the cigarettes are readily accessible to the user -of the case. The plate 7 may have ears, formed at each end, at right angles to the hinge axis, so as to retain a number of cigarettes on the plate. In another embodiment of the present invention the plate 7 may extend from one end of the panel 2 to the other so that all the cigarettes are tilted up as a consequence of opening the case, and in such an arrangeaa ment axis Din for the Vee shaped element may extend from each end of the panel in -alignment with each other and with the axis member 11, although sufficient support for the Vee shaped element may be provided by -ii O the pins alone in which case the axis member it may be omitted. By a construction of tiltable plate as herein described a very simple device, easily attached to a conventional form of cigarette case, is provided and which is operable as a result of opening the case to make some or all of the cigarettes therein readily accessible to the user, thus only the cigarettes taken out are fingered by the person withdrawing the cigarettes.
