UNITED STATES PATENT OFFIC GEORGE FAUSTMANN, OF PHILADELPHIA," PENNSYLVANIA.

LEATHER-SPLITTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 374,401, dated December 6, 1887. Application filed September 2, 1887. Serial No. 248,623. No model.)

Be it known that I, GEORGE FAUSTMANN, of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Leather Splitting and Trimming Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings,which form part of this specification.

My invention relates to an improvement in leather splitting and trimming machines; and it consists in the combination of a suitable framework, a knife secured rigidly thereto, a pivoted spring actuated frame carrying a roller for pressing the leather up against the knife, and a connection to the treadle, as will be more fully described hereinafter.

The object of my invention is to provide a machine which is especially adapted to the use of book binders and upholsterers, and which will not only split leather, but can be used for paring down the sides of the leather strap, and which is open at one end, so that the work can be freely inserted and removed whenever desired.

Figure l is a perspective of a machine embodying my invention. Figs. 2 and 3 are detail views of the knife or cutter.

A represents asuitable metallic frame,which is secured rigidly to the table, and from which rise the two uprights B, which have the shoulder 0 formed on their inner sides to form sup ports or rests, to which the handle of the knife or cutter D is rigidly secured. Extending laterally from the tops of the two uprights D is the arm or hearing F, which is provided with a shoulder, G, against the underside ofwhich the outer end of the knife or cutteris secured. This knife or cutter being held from both above and below, it can have no movement of any kind, even should the tightening bolts become somewhat loosened.

Placed upon the tops of the two outer corners of the frame A are the two uprights or supports H, which have suitable slots, I, made through their bases, so that the posts can be adjusted back and forth, and thusl change the relative relations of the knife or cutter D to the roller J. These posts or pillars H can be adjusted back and forth upon the frame A the full length of the rods I, and thus move the roller J back and forth in relation to the edge of the fixed knife or cutter D, according to the kind of work that is being done. This rollerJ isjournaled in the frame L, which is pivoted at its outer corners to the post H, and which is supported at its inner '60 end by the spring O,of any suitable construction. The upward pressure of the spring 0 against the frame L keeps the rollerJpressed upward against the under side of the knife, and thus serves as a support for the leather 6 while it is being operated upon. The knife is the same length as the roller J, and hence there is a space left at one end of the roller J to freely insert and remove the work at the will of the operator. One corner of the knife 72 is turned up, as shown at P, Figs. 1 and 3, so

as to make an even and gradual bevel upon the edge of the leather. There being an open space at one end of the knife-edge enables the party using the machine to cut down or bevel 5 each side at pleasure.

To an arm formed on the rear edge of the frame L is attached a connectingrod, Q,'for the treadle. The operator, by bearing down upon the treadle, can depress the frame L, so that the roller will be moved away from the cutter, and thus allow-the work to be freely inserted and removed at will.

Having thus described my invention, I claim- The combination of the uprights B, having the beam F extending outward from them; the knife D, which is secured to the uprights B, and the arm F, the uprights H, the pivoted spring-actuated frame L, and the roller J, a 0 space being left between the knife 'and the roller at one end for the removal and insertion of the work, substantially as shown.

In testimony whereof I aflix my signature in presence of two witnesses.

GEORGE FAUSTMANN.
