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
773,591	Nov. 01, 1904	Multiple-spindle drill-press	Charles De Los Rice	Hartford, CT	This patent date was seen on a drill press from Henry & Wright Mfg. Co. of Hartford. We have also seen an undated condensed catalog from British maker Smith & Coventry, Ltd., which is titled "Sensitive Drilling Machine (Rice's Patent)". The text inside refers to "patents" and we presume that Rice's various drill press patents were all licensed by that maker.

877,157	Jan. 21, 1908	Manufacture of wood-screws	William G. Allen	Hartford, CT	This patent provides improvements to the process of manufacturing rolled-thread wood screws. Cut screws were expensive to manufacture, and the metallurgical requirements for cutting threads were, to some degree, incompatible with the requirement for swaging the heads. The result was a screw that was brittle and prone to breakage. On the other hand, rolled-thread screws, traditionally produced by forcing wire screw-blanks between a pair of dies a fixed distance apart, were sensitive to slight variations in the wire thickness caused variations in the quality of the threads. In addition the screw heads were swaged first, and wear in the head dies caused variations in shank diameter, which led to malformed threads and jamming of the dies. On the other hand, rolled-thread screws avoided the disadvantages of the cut-thread screws. The new method begins by "rolling the groove between the threads", followed by cutting or grinding the threads to the proper completed form. This additional step allows for variation in the shaping of the thread and removes irregularities. The method proposed that the first step could also be done by cold-swaging, which was reported to be suitable for bolts, where rapidity of production is not as important. The Glbe screw Co. was established in 1907 by the inventor, William G. Allen, along with Robert G. Henry and Daniel M. Wright, who were the principals of Henry & Wright Mfg. Co., manufacturers of light machinery and hardware specialties. See also patent 928,489, which describes the screw-making machinery in more detail.
928,489	Jul. 20, 1909	Screw-thread-cutting mechanism	Robert G. Henry	Hartford, CT	This machine produces the rolled-and-cut threads on wood-screws as described in patent 877,157.
		Screw-thread-cutting mechanism	William G. Allen	Hartford, CT
981,390	Jan. 10, 1911	Belt-gearing	Charles De Los Rice	Hartford, CT	The manufacturer information is somewhat speculative: the patent was not explicitly assigned to Henry & Wright but an early patent to this inventor, 773,591, is known to have been used by that firm. Rice seems to have been a professional inventor as his numerous patents span machine tools, streetcars, trains, typewriters, and tire repair. Most of his patents were not explicitly assigned.
984,708	Feb. 21, 1911	Belt-gearing	Charles De Los Rice	Hartford, CT	This patent was used by multiple drill press manufacturers. "The invention consists mainly in belt gearing comprising step cone or multiple pulleys on the driving or driven shaft, or, preferably, on both, and intermediate pulleys or idlers and provisions for varying and determining the position thereof so that each step or pulley of one shaft may coÃ¶perate with any step or pulley on the other shaft, and the belt be properly guided tightened to transmit the rotary movement from one shaft to the other..."
