		Improvement in couplings for shafting	William Sellers	Philadelphia, PA
36,512	May. 08, 1858	Injecteur alimentaire pour machines Ã vapeur	Henri Giffard	, France	This is the very famous Giffard injector, which had no moving parts and caused quite a furor because its operation seemed to violate the laws of thermodynamics. Giffard had derived its design from first principles. Others had independently discovered the basic idea but their injectors were difficult to get started. Giffard's invention includes a small overflow reservoir which solved the startup problem, and customer tests, including on steam locomotives, quickly demonstrated the superior performance of Giffard's injector. It was licensed to others, including Wm. Sellers in the US. See also US patent 27,979 and British patent 186,402,789.
27,979	Apr. 24, 1860	Improved feed-water apparatus for steam-boilers	Henry Giffard	, France	An 1860 catalog for the Tredegar Iron Works of Richmond, Va., has a page on "Giffard's patent self-acting water injector for feeding boilers. Made by William Sellers & Co., sole manufacturers and licensees..."

36,112	Aug. 05, 1862	Improvement in boring-mills for metal	William Sellers	Philadelphia, PA
39,313	Jul. 21, 1863	Improvement in the Giffard injector	William Sellers	Philadelphia, PA	Wm. Sellers & Co. was the exclusive US licensee of "Giffard's patent self-acting water injector for feeding boilers." This patent provides improvements on Giffard's patent 27,979, to improve the packing between the steam and water chambers, and to reduce size and weight of the injector.
42,797	May. 17, 1864	Planing Machine for Metal	William Sellers	Philadelphia, PA	The objects of my invention are, first, to effect the lifting of the tool from the work on the back-stroke of the planer in any position of the slide-rest; second, to provide a thorough protection to the wearing-surface of the slides from the chips or dirt incidental to the working of the machine; third, to insure a constant and uniform lubrication of the slides without undue loss of oil. All planing-machines for metal of improved construction are so arranged as to be able to adjust the feed for planing horizontal, vertical, or angular surfaces, and such planers are advertised as having positive geared feeds self-acting in all directions. The horizontal feed is in every case obtained from the motion of the saddle on the cross head, while the vertical and all the angular feeds are obtained from the slide-rest upon the saddle, which may be set vertically or have its line of motion adjusted to any angle with the cross-head. This, of course, necessitates the turning of a portion of the saddle on a center, and through this center the power to operate the downfeed is in most cases conveyed. In order to relieve the tool from needless wear during the back-stroke of the planer-table, it is hung in what is called an " apron," so adjusted as to allow the tool to swing loose on the backstroke of the planer-table, but to be held rigidly when cutting. In large planers, when the weight of the tool is great, and in all fine planing, this liberation of the tool is not sufficient of itself, but some arrangement must be added whereby the tool-point shall be actually lifted clear of the work on the back-stroke and dropped into place ready for the cut after the article to be planed has passed under it. By my invention I am enabled to lift the tool in every position of the slide-rest, and to do so from within the cross-head without interfering with any of the machinery for working the feeds, which, as I have before said, occupy the center about which the adjustable part of the saddle rotates.
43,137	Jun. 14, 1864	Metal Planing Machine	William Sellers	Philadelphia, PA	The objects of my invention are to provide a means of dressing plane surfaces of metal in a more rapid and perfect manner than has heretofore been done, and also to provide a means of dressing the opposite sides or ends of the same piece at the same time. I effect this object by making use of rotary cutterheads, which carry a succession of tools acting consecutively upon the metal to be planed, the cutter-heads having their bearing or support so arranged as to give great steadiness to the cut, while the work is held upon tables which admit of ready adjustment.
46,714	Mar. 07, 1865	Machine for Rifling Gun Barrels	William Sellers	Philadelphia, PA
		Machine for Rifling Gun Barrels	Coleman Sellers	Philadelphia, PA
49,445	Aug. 15, 1865	Giffard Injector	William Sellers	Philadelphia, PA
55,723	Jun. 19, 1866	Machine for Planing Metal	William Sellers	Philadelphia, PA	In nearly all planing-machines for metal the work is fastened to a table sliding back and forth on ways which control its position. To the ways are secured uprights, and to the uprights are fastened what is termed the "crosshead," this being the cross-slide of the compound slide-rest holding the planing tool. The crosshead is adjusted upon the uprights at varying distances above the table to suit the size of the work to be planed. Some few machines have been built with the cross-head attached to slides moving and guided in ways fastened to walls of masonry, motion being communicated to the slides and cross-head by means of screws or chains attached to and supported by the ways, and the materials to be planed resting on platforms in the pit formed by the side Avails. The crosshead having no vertical adjustment, the platforms which support the work are raised or depressed to suit the varying heights of the material. A modification of this form has also been employed that is to say, in order to decrease the depth of the pit, short uprights have been used, sliding in ways on top of the walls, the cross-head having an adjustment vertically upon these; but all machines of this class have heretofore used platforms to support the material to be operated upon, which are either adjustable in height to suit the varying heights of the material, or require that this, when small, should be elevated above the platform, to come within reach of the planing tool. Supposing the disadvantages overcome in this form of machine, it would be found well adapted to the heavier class of work, as it "would take up much less room, the moving parts could always be of the same weight, and generally much lighter than the work to be operated upon, so that it would require less power to drive it. The object of my invention is to overcome the disadvantages in this class of planing-machines and the nature of it consists in supporting the work to be operated upon on a stationary platform and the cross-head upon uprights or posts, as in machines of ordinary construction; but these uprights are so arranged as to slide in ways provided for that purpose in the sides of the stationary platform, so that the slides which govern the position of the tool are below the work to be operated upon in place of above it, as heretofore, and the cross-head can be elevated and depressed upon the uprights to suit the varying heights of the work, in place of elevating and depressing the platform.
