MACHINE FOR SPLITTING LEATHER.

Specification of Letters Patent No. 8,227, dated July 15 1851.

To all whom it may concern: y I

Be it known that I, WILLIAM PANTON, of Milton, in the county of Norfolk and State of Massachusetts, have invented an Improve-' ment in Machinery for Splitting Green or Wet Hides; and I do hereby declare thatthe same is fully described and represented in the following specification and accompanying drawings, letters, figures, and reference thereof. Of the said drawings Figure 1 denotes a top view of my improved machine. Fig. 2 is an elevation of that side of it on which the cutting knife is placed. Fig. .3 is a transverse and vertical section of it. Fig. 4 is an end view of it. In the said drawings A. represents the frame work by which the operative parts are supported in their respective positions.

B and C are two feed rollers, made small in their diameters and respectively supported by two larger rollers D, E, arranged with respect to them as seen in the drawings.

F is a long blade or knifewhose cutting edge is placed in the angle of the two rollers B, C. The said knife is fastened to a sliding frame G, which rests upon slide ways or guides, as seen at a, a, a, a, soconstructed and arranged as to permit it and the knife to have a reciprocating rectilinear movement ina longitudinal direction, such movement being imparted to them by means of a connecting rod I, jointed to a crank plate K, which is fixedon one end of a horizontal shaft L. The shaft L receives its motion from another shaft M, by means of two bevel or toothed gears N, O.

From a pulley P, on the shaft M, an endless crossed belt P, is carried up and around the pulley Q, fixed on the shaft R of the roller D, and from the shaft R, motion is communicated to the feed roller by means of a train of gears S, T, U,V, the gear S being fixed on the shaft R, while the gears T and U, are fixed on the shaft W of the upper feed roller. The gear V, is fixed on the shaft of the lower feed roller;

When the crank shaft M, is put in rotation in the proper direction the several rollers and the cutting knife will be put in movement, the direction of themovement of the said rollersflbeing denoted by the arrows placed thereon in Fig.3. The axles or shafts of the rollers should be supported by proper boxes or bearings. The upper feed roller is to be constructed of iron or some other equally unyielding or indurated material, I while the lower feedroller is to be made of an elastic or yielding curved surface, and for this purpose I make it of some elastic or other suitable material, which. will insure to it the proper degree of elasticity. In ordinary leather splitting machines, such roller has been made a spring roller that is to say, while it was constructed of hard substance, such as iron or leather, its journals were upheld by springs, which permitted the whole roller or either end of it to move downward, the roller being borne up against the leather by such springs. l i

As my machine is for splitting green or wet hides, whose fleshy side is to lie against the surface of the under feed roller, and as such fleshy side is generally very uneven, the hide cannot wellbe split to an even thickness, when a spring unelastic roller is used, butby employing an elastic roller made with I a yielding elasticsurface which will readily lower one, such as is usually termed a spring or pressure roller or one having a hard or practically inelastic surface, but What I do claim as my improvement in machinery for splitting or dressing. wet

hides is v The employment of an elastic surface roller (or roller made ofgum elastic or other like material placed around an axle or shaft) and an inclosure roller (as feed rollers) in connection with the cutting knife made either stationary or what is better to have a vibratory or reciprocating motion, all substantialy as hereinbefore specified.

H In testimony whereof I have hereto set my signature this fifth day of March, A. D. 1851. I a

WILLIAM PANTON. Witnesses: i
