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
1,360,482	Nov. 30, 1920	Dynamo-electric machine	John B. Wiard	Lynn, MA	The inventor, John B. Wiard, worked for H. C. Dodge, Inc., which was purchased by woodworking machinery maker S. A. Woods Machine Co.
1,360,483	Nov. 30, 1920	Dynamo-electric machine	John B. Wiard	Lynn, MA	"This invention relates to dynamo electric machines and more particularly to provisions for dissipating the heat in such machines by the introduction of cooling air." This patent was subsequently improved in a patent, 1,679,457, that was assigned to H. C. Dodge, Inc. of Boston. Mr. H. C. Dodge was the president of woodworking machinery maker S. A. Woods Machine Co., and H. C. Dodge, Inc., was bought out by S. A. Woods Machine Co., and therefore this patent was used on motors for woodworking machinery. Patent 1,805,437 was co-invented by John B. Wiard and assigned to S. A. Woods Machine Co.
1,479,636	Jan. 01, 1924	Dynamo-electric machine	John B. Wiard	Lynn, MA	The inventor worked for motor maker H. C. Dodge, Inc., and later for woodworking machinery (and motor) maker S. A. Woods Machine Co.
1,541,370	Jun. 09, 1925	Setting, grinding, and balancing machine	Louis T. Medholdt	Winthrop, MA	This invention sets, grinds and balances the knives in a planer cutterhead. It was advertised by H. C. Dodge Co. as their "S-B-G Unit" or "S-G-B Unit". The ads began in 1924 and disappeared before the end of 1925.
1,679,457	Aug. 07, 1928	Dynamo-electric machine	John B. Wiard	Lynn, MA	"This invention relates to dynamo electric machines and more particularly to improvements designed to dissipate the heat arising from internal losses in such machine. The invention has for its object the provision of an effective cooling or ventilating system embodied in the machine itself in simple, compact form particularly, though not exclusively, intended for high speed direct-connected, induction motors where the constructional features render the ordinary methods of cooling impracticable... one embodiment of the invention in an alternating current motor of the induction type which is mounted on the frame of a wood-working machine directly connected to drive a working part thereof, such as the cutter head 5." Harry C. Dodge was later the president of S. A. Woods Machine Co., and it is my hypothesis that he started as a motor manufacturer with his own firm and was subsequently bought out by S. A. Woods Machine Co. S. A. Woods became well known for their very high quality motor, including direct-machine-drive applications as described in this patent. This patent is an improvement on the inventor's earlier patent 1,360,483.
1,773,712	Aug. 19, 1930	Apparatus for controlling electric motors	John B. Wiard	Lynn, MA	"This invention relates to apparatus for co-ordinately controlling the starting of different motors of a group so as to automatically prevent the operation of some one or more motors, or of devices driven thereby, during the period that one or more other motors of the group are being started and brought up to speed... As a specific illustration of such a case there may be instanced the use of motors in a wood-working machine where one motor is employed for driving the feed mechanism and a number of other motors used for driving the cutting devices which cut or shape the work when the latter is fed within their working range." The inventor worked for motor maker H. C. Dodge, Inc., and later for woodworking machinery (and motor) maker S. A. Woods Machine Co.
