WM. S. MARSH, OF INDIANAPOLIS, INDIANA.

,IMPROVED SKIVING AND SPLITTING MACHINE.

Specification forming part of Letters Patent No. 48,964, dated July 25, 1865.

To all whom fit 'may concern.-

Be it known that I, WM. S. MARSH, of Iudianapolis, in the county of Marion and State of Indian a, have invented a new and useful Machine for Skiving and SplittingLeather Straps, called Eureka Skiving and Splitting Knife and I do hereby declare that the following` is a full, clear, and exact description of the construction and operation ot' the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 is a perspective View, and Figs. 2, 3, and 4 sections, in which- AAAA,&c.,is thet'rame; B,the knife; CO, the thumb-screws; D, the sliding plate; E, the movable carriage, which slides in the slides G G; H, the set-screw; J, the spring; K, the nut of the rod P; L, the roller; N N, the feet; O, the check-rib; It, the pivot-pin, and S the leather strap.

The nature of my invention consists in constructing a frame-work, A A A A, Src., supplied with feet N N N N, by which the frame is to be screwed to the bench. I attach slides G G to the insideV of Ithis frame and place my carriage in them. Connected with this carriage, and fastened to it in the rear, and by means ot' a pivot-pin, R, is the slide-plate D, which is inclined, as shown on drawings. In front of the carriage is the set-screw F, which passes through the carriage E to the under side ol' the inclined sliding plate I). I place my knife B on top of the frame A, Snc., and fasten it down by means of the thumb-screws C C. Then I place my roller L immediately bi fore and right over the edge of the knife B, and tasten it down by means of iron rodsPP working through nuts K K. I then place my springs J J on the outside of the frame in such a manner as to hold the rods on the place, while they still give them some play, so as to permit the roller L to adjust itself to the thickness ot' the strapon the sliding plate D. I attach the check-rib O to the under side of the carriage E diagonally, as shown in Fig. 4, and place lny set-screw H in such a way as to work upon that cheek-rib 0. Thereby I construct a machine which will skive and split leather rstraps of any desired size, thickness, or taper.

Operation: By means of the set-screw F,

which passes through the carriage E to the under side ofthe slide-plate D, I can so set the slide-plate D as to skive a strap with either a long and slim or short and thick taper. If a feathenedge is desired, one end of the strap is placed to the farther end ot' the slide-plate D, (opposite the knife,) and if a thicker edge is wanted the strap must be dropped back toward the knife to correspond with the space between the frame-top and slide-plate D. By raising the set-screw F, I get a long and gradual taper; by lowering the same a short and thick one. rlhe strap must he held rmly down upon the slide-plate D and, together with it, drawn through the adjustable roller L and knife B. For splitting straps I move the slide-plate D so far out of the frame in front as to get the space between the knife B and slide-plate D equal to the desired thickness of the leather strap. I then set the set-screw H so as to bear against the check-rib O, thereby preventing the slide-plate D from passing farther out of the frame than desired, shoving the slideplate back again, and placing the strap upon the slide-plate D and bringing it hack to its place. l can split a strap at the thickness desired by drawing it through the roller L and knife B. In this manner, keeping the set-screw H at irs place, I can split any number of straps of precisely the same thickness.

I do not claim the knife B nor the roller L; but

What l do claim as my invention, and de.

WM. S. MARSH.
