Patent Number	Date	Title	Name	City	Description
17,814	Jul. 14, 1857	Centering-machine	Edward F. Whiton	West Stafford, CT	This centering machine seems to inspired D. E. Whiton's first foray into manufacturing machine tools. He subsequently developed a very successful line of lathe chucks and then diversified into engine lathes and gear cutting machines. His company survived into the 1960s.
58,704	Oct. 09, 1866	Improvement in chucks	D. E. Whiton	West Stafford, CT	This is the earliest chuck patent for D. E. Whiton that we have found. D. E. Whiton Machine Co. was a dominant manufacturer of lathe and milling machine chucks, especially scroll chucks.
203,571	May. 14, 1878	Improvement in drill and lathe chuck attachments	David E. Whiton	West Stafford, CT	"My invention relates to a new and useful attachment for drill and lathe chucks, for the purpose of operating the jaws of the chuck to and from each other; and this my invention consists of a detachable bearing, in which is located a worm-shaft operated by means of a suitable handle, in combination with a worm-gear on the back plate or movable part of the chuck, by which arrangement the chuck can be very easily operated, so as to open or close the jaws simply by temporarily attaching the detachable bearing carrying the worm-shaft, and turning the handle thereof in the desired direction..."
224,119	Feb. 03, 1880	Scroll-chuck	David E. Whiton	West Stafford, CT
294,296	Feb. 26, 1884	Lathe-chuck	David E. Whiton	West Stafford, CT	"Our invention relates to that class of lathe-chucks whose jaws are moved radially in guide ways or slots made in the front face of the shell or case by a rotary disk operated by pinions within the shell, and provided with a convolute or scroll thread made on its outer face, which engages in the teeth made on the back side of each jaw. The object of our invention is to secure the greatest strength, durability, and accuracy in and to completely inclose all the actuating parts, to give easy access to the same when desired, and to provide means to secure the back plate to the shell at the same time the chuck is secured to the chuck-plate..."

316,713	Apr. 28, 1885	Lathe-tool	Lucius E. Whiton	West Stafford, CT
366,749	Jul. 19, 1887	Lathe-chuck	Lucius E. Whiton	New London, CT	"I am aware that lathe-chucks have heretofore been devised in which a scroll-shaped cam provided with worm-teeth was made to operate the jaws, the cam being operated by a screw-key or worm; but I am not aware that any have been heretofore devised in which a detachable screw-key engaging with worm-teeth on a central core has been applied in holes on opposite sides of the shell for tightening or loosening the grip."
369,758	Sep. 13, 1887	Lathe-chuck	Lucius E. Whiton	West Stafford, CT	An example of this patent lathe chuck has been seen. This design was subsequently improved in patent 422,479.
422,480	Mar. 04, 1890	Chuck	Lucius E. Whiton	New London, CT	"my present invention is especially applicable to that class of chuck in which a series of holding-jaws are supported in radial guide-ways and actuated by a scroll or helix on a revoluble section located within the chuck-case. The purpose of my present invention is to simplify and cheapen somewhat the manner of supporting and securing said pinion-gears..."
422,479	Mar. 04, 1890	Chuck	Lucius E. Whiton	New London, CT	"On September 13, 1887, Letters Patent No. 369,758 were issued to me for certain improvements in that class of chucks having a series of radially movable jaws, one feature of said improvements being a thrust pin or bearing... that was provided to prevent undue endwise play of the screws that operate the said jaws. In manufacturing chucks embodying such thrust-bearings I have found the particular form described in said earlier patent somewhat difficult and expensive to make, although when made and put to service it performs its office satisfactorily. My object in this present invention is to both simplify and cheapen the construction of such thrust-bearings, and at the same time to increase the resisting-surface of such bearings, so that there shall be no possibility of their becoming loosened or displaced by constant and severe use."
425,279	Apr. 08, 1890	Reversible jaw for chucks	Lucius E. Whiton	New London, CT	These chuck jaws are described in detail in an 1896 catalog from D. E. Whiton Machine Co. It that this type of jaw "is best adapted to the smaller sizes, in which the Jaws may be very conveniently run out to be reversed. This style Jaw avoids the necessity for using small screws to fasten the parts, and the steps in the Jaws, being solid, may be trued up whenever necessary." Another style of jaw is recommended for larger chucks where it would take too long to unscrew them to reverse them; instead, the jaws slide into dovetailed ways and are held in place with a screw. ...we do not recommend these Reversible Jaws as being fully equivalent to the two sets of solid jaws commonly furnished. The Reversible Jaws are not as convenient and are liable to be less accurate; they are also not as durable, having only one set of bottom sliders to engage with the scroll, but Chucks so fitted are less expensive than Chucks with two sets of Jaws."
426,347	Apr. 22, 1890	Drilling-machine	David E. Whiton	New London, CT	"Our invention relates to that class of machines in which rods or other work are prepared for turning, and which are commonly provided with a laterally-movable head having two spindles, one of which carries a drill and the other a reamer..."
		Drilling-machine	Lucius E. Whiton	New London, CT
437,068	Sep. 23, 1890	Speed-changing mechanism for lathes	Lucius E. Whiton	New London, CT	"This invention has special relation to so-called 'back-gearing,' used commonly in engine-lathes, drill-presses, and the like machines for increasing power, and seeks to improve the construction of such mechanisms..."

1,713,803	May. 21, 1929	Lathe chuck	Lucius E. Whiton	New London, CT	"One object of my invention is to provide a chuck for holding irregularly shaped stock and permitting adjustment while the chuck is rotating. Another object is to provide such a chuck in which the jaws can be adjusted with substantially equal pressure while the chuck is rotating or stationary. Another object is to provide a construction of this character which is compact and reliable and will permit the stock or tools to be fed through the chuck. Another object is to provide a construction of this character in which the pairs of jaws can be adjusted independently or together."
