Patent references: May 16, 1893 (497,522 US Patent)16 mai 1893 réfère à de multiples brevets présentés par Adrian H. Hoyt de Manchester, N. H., qui était ``assignor`` pour la Whitney Electrical Instrument Co.

Ces brevets sont la plupart pour un galvanomètre mais l’un de ceux-ci concerne un instrument de mesure électrique, no. 497,521. (The Electrical Age, Volume 11, May 27, 1893, p. 337)

Period of use: Area of use: Peterborough, Ontario

Significance to Canada:

Ampèremètre fabriqué et utilisé au Canada.A été utilisé à la Peterboro Ontario Institute & Voc, School. (Peterborough Ontario Institute and Vocational School). Il s’agit d’une école dont les origines remontent à 1826.

Fait partie de la collection Hydro-Ontario. Cette collection acquise par le musée des sciences et de la technologie du Canada en 1992 documente la culture matérielle de l’histoire de l’électricité et ses usages. Hydro-Ontario a obtenu cet artefact de la Canadian General Electric en juin 1968.

Ammeter made and used in CanadaThis ammeter was used at the Peterboro Ontario Institute & Voc. School.Part of the Ontario Hydro Collection. This collection was acquired by the CSTM in 1992. It documents the material culture of the history of electricity and its uses. Ontario Hydro received it from Canadian General Electric in June 1968.

La compagnie WHITNEY a manufacturé des appareils de mesure électriques à Sherbrooke de 1893 à 1895 ? Suite à l’incendie, peut-être n’a-t-elle pas reconstruit ou déménagé l’usine ailleurs à Sherbrooke.

CANADIAN NOTES.The Whitney Electrical Instrument Co.'s Canadian worksat Sherbrooke, Que.,were badly damaged by fire on Dec.29.The plant and stock were damaged about $10,000, while there was insurance on about $5,000. Canadian orders will be carefully executed at the Whitney American factory at Penacook, N.H., until the Canadian works are rebuilt. Mr. C. E. Shedrick is the electrician and superintendent of the plant at Sherbrooke(THE ELECTRICAL ENGINEER, January 9, 1895, vol.XIX, no. 349, p. 42. Online)Ce C. E. Shedrick est le même homme qui a inventé la minuterie OH0854.013. En 1898, 1901 encore, il vendait les produits de la Whitney Electrical Instrument Company en tant que titulaire de licence de la firme. Peut-être qu’après l’incendie, l’usine n’a pas été reconstruite et que la firme s’est contentée d’avoir un représentant ?.

OH0854.013 Minuterie inventée par le Canadien Charles E. Shedrick, fabriquée et utilisée au Canada.

En 1901, Charles E. Shedrick vendait des appareils de mesure et de radiographie et était le titulaire au Canada des produits brevetés de la Whitney Electrical Instrument Company. Il était alors situé à Sherbrooke, Québec. Vers 1906, la firme déménagea à Montréal au 157 rue Craig pour devenir la Shedrick Rigby Company Limited. C. E. Shedrick et Jno S Rigby junior sont partenaires d’affaires. Toutefois, déjà en 1908, seul C.E. Shedrick semble demeurer en affaires jusqu’à environ 1916. Un avis de liquidation paru dans la Gazette du Québec en 1909 confirme cette hypothèse.

En 1893, la compagnie-mère était localisée à Boston, Massachusetts

Brevet du 16 mai 1893 réfère à de multiples brevets présentés par Adrian H. Hoyt de Manchester, N. H., qui était ``assignor`` pour la Whitney Electrical Instrument Co.Ce même Hoyt était originaire de Magog, Québec, localité située près de Sherbrooke.Il était aussi beau-frère de Charles E. Shedrick, né aussi à Magog. Hoyt est également beau-frère de Whitney. Voir :

Birth:  Mar. 7, 1862MagogEstrie RegionQuebec, Canada

Death:  Oct. 20, 1920ConcordMerrimack CountyNew Hampshire, USA

Born to Joseph Hoyt & Susan Currier in Magog, Quebec, Canada. He studied at the business college, Davis & Dewey in Montreal and later received his M.D. at Dartmouth College. On June 13, 1887, he married Lizzie C Schedrick, dau of Daniel & Almeda in Magog. Despite his medical degree, his interest was electrical devices. He secured over 25 patents for electrical measuring devices and instruments, including his invention for an alternating current ammeter. A number of his inventions are used in the production of automobiles. Perhaps because of his close association to the early automobile industry, he is said to have been the first person in the State of New Hampshire to own one. He was a member of the Methodist church, Order of Odd Fellows, and a 32nd degree Mason.

He and his wife had one children, Wallace Hoyt, b. 1888, perhaps named for his brother.  Family links:  Parents:  Joseph Hoyt (1817 - 1876)  Susan Currier Hoyt (1821 - 1891)   Spouse:  Elizabeth Clara Shedrick Hoyt (1868 - 1945) *  Siblings:  Wallace Nelson Hoyt (1842 - 1868)*  Alwilda Amanda Hoyt Whitney (1845 - 1924) *  Arretta Florence Hoyt Whitney (1847 - 1903) *  Alfaretta Jane Hoyt (1849 - 1858)*  Adrian Hazen Hoyt (1862 - 1920) *Calculated relationship Burial:Woodlawn Cemetery PenacookMerrimack CountyNew Hampshire, USA(Information tirée de Adrian Hazen Hoyt, nécrologie à http://www.findagrave.com/cgi-bin/fg.cgi?page=gr&GRid=80127891)

``Hoyt Electrical Instrument Works; New Hampshire: Adrian Hoyt started to work for Whithney Company in the 1880s and by 1888 Whitney was building ornate, brass cased station meters. Whitney moved from Manchester to Penacook NH in 1892. In 1904, Hoyt started his own company in Penacook when Whitney merged with Roller-Smith in Bethlehem PA. ``

Do You Really Know The History of Hoyt Electrical Instrument Works?Angela Hutchinson, Jun 11, 2015

La Whitney Electrical Instrument, incorporée en 1891 semble être devenue la Hoyt Electrical Company. (http://www.penacookhistoricalsociety.org/Quilt/quilt9.htm)

Significance to technology: Patent May 16, 1893

``Hoyt Electrical Instrument Works Inc has been manufacturing in Penacook NH since 1904 but did you know Hoyt's founding father Adrian Hazen Hoyt did not start out manufacturing electrical instrumentation? Hoyt was born in 1862 in Magog a Province of Quebec where he attended the grammar schools and the business college of Davis and Dewie in Montreal? He was also a 1887 graduate of Dartmouth College, with the degree of M.D.  Hoyt started his own practice in Magog but finding it not congenial to his bent of mind;  he relocated to St. Johnsbury, Vt. where he entered the employ of the Standard Electric Company. This is where Hoyt learned of his love for electricty and a year and a half later he moved to Manchester NH, where he engaged in electrical experimental work for several years. A number of these devices were used in the construction of automobiles, in which Dr. Hoyt had always taken a deep interest in, he was also one of the first in America to make practical use of the X-ray.      In 1880 he accepted the position of manager of the Whitney Electrical Instrument Company and by 1888 Whitney was building ornate, brass cased station meters. Whitney then moved from Manchester to Penacook NH in 1892. When the company moved to Penacook Hoyt followed establishing a residence and continued as superintendent and manager of the company, filling those positions until early 1900 where he built and engaged in business for himself.  He erected a shop that employed a number of mechanics in the manufacturing of automobiles and electrical instrumentation, where he was manufacturing his own line of well known "direct reading" meters. At this time Dr. Hoyt began to build his steam cars at his American Manufacturing Company in Penacook. ``
