Key to Links for Patent Information

USPTO = U.S. Patent Office . Images of the actual patent can be viewed on the U.S. Patent Office web site but a special TIFF viewer must be installed with your browser in order properly work. More information on how to configure your computer to view these patents can be found at TIFF image Viewers for Patent Images.
DATAMP = Directory of American Tool And Machinery Patents . A sister site to VintageMachinery.org with information on patents related to machinery and tools. A much easier user interface than the USPTO's for finding information on machinery patents.

Patent Number Date Title Name City Description
57,466 Aug. 28, 1866 Improvement in ratchet-drills George W. Bishop Stamford, CT In 1868, Bishop & Fairchild incorporated as the New England Manufacturing Works & Co., which seems to have disappeared within a year or so. Thus far we have no reports of a surviving example of this drill, although an 1866 newspaper article mentions that it was being made by Bishop & Fairchild.
58,765 Oct. 16, 1866 Improvement in friction-clutch pulleys George W. Bishop Stamford, CT
69,533 Oct. 08, 1867 Improvement in drilling machines George W. Bishop Stamford, CT This patent covers the swinging and rotating table, which was a significant advance in post-drill design, and was copied by numerous other manufacturers. The assignee, Veeder Colegrove, is a bit of a mystery. All we can find of him is that he was born in 1823 in Adrian, Michigan and died in 1889 in Greenwich, Connecticut. The findagrave.com website gives his name as "Veeder 'Peter' Colegrove".
71,358 Nov. 26, 1867 Ash-sifter George W. Bishop Stamford, CT
75,116 Mar. 03, 1868 Improvement in gates George W. Bishop Stampford, CT
78,178 May. 26, 1868 Improvement carpet-cleaning machine George W. Bishop Stamford, CT
89,461 Apr. 27, 1869 Wrench George W. Bishop Stamford, CT A cam-faced lever bears on the outside of a drill chuck or wrench socket. Neither the cam face or exterior of the chuck / socket have teeth. A stop pin limits "lost motion" of the lever.
144,731 Nov. 18, 1873 Mechanisms for Reversing Engines George W. Bishop Brooklyn, NY From a descendant of the inventor, Carol Bishop Fisher:

His last patent was for the Mechanisms for Reversing Engines (# 144,731 - Nov. 18, 1873) was possibly his least known, in his attempt to join the masses of inventors trying to solve the problem of the reverse mechanism for the steam engine. My ancestor's ingenious invention simplified the reversing mechanism by using rotary valve-blocks in place of the usual assortment of complex levers and link-motions which were then in use with less satisfactory results. Previous attempts to introduce sliding valves were unsuccessful because of the friction created by the steam pressure on the sliding block or plate, but this rotary valve eliminated this problem.
To this day it is the opinion of mechanical engineers that the steam engine reversing mechanism has never been perfected. G. W. Bishop became ill and escaped notice in mainstream technical literature of reversing gears. Had the George W. Bishop mechanism been tested, it may have proven to solve not only the problems of complexity and unreliability, but also the theoretical errors of port opening and timing introduced by lever and link-motion reversing mechanisms.
