IMPROVEMENT IN MACHINERY FOR SPLITTING AND BEVELING LEATHER.

Specification forming part of Letters Patent No. 196,197, dated October 16, 1877 application filed September 6, 1877.

To all whom it may concern:

Be it known that we, CHRISTIAN DANCEL, of the city, county, and State of New York,

and EDMoND C. SMITH, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Machine for Splitting and Beveling Leather and other materials, which invention is fully set forth in the following specification, reference being had to the accompanying drawing, in which- Figiire 1 represents an elevation, showing one side of our machine. Fig. 2 is a similar view, showing the other side. Fig. 3 is a transverse vertical section in the plane w a,

- operation. The diameter of the feed-roller increases at one end to correspond to the curvature of the cutting-edge of the knife, so that the same will take hold of and feed the materia-l when being passed through the machine for the second time, and after it has already been split by the rst operation. The knife is so arranged that it can be adjusted toward and from the gage-roller, and also in the direction of the .length of this roller; and its cutting-edge is made longer than the feed-roller, so that when it is adjusted in the direction of the length of the gage-roller its cutting-edge will always act throughout the entire length of the feed-roller. The feed-roller is moimted in a head which is adjustable toward and from the knife and the gage-roller, and its shaft is made in' two sections, which are connected by a universal joint, so that said shaft will remain in gear with the driving-shaft, and the feedroller, when `being moved up or down, will remain parallel with the gage-roller.

In the drawing, the letter A designates the frame of our machine which forms the bearings for the driving-shaft B. On one end of this driving-shaftis mounted a handle or winch, C, and on its other end is firmly secured a smooth roller, D, which we term the gageroller. From the bed-plate of the frame A rises a hollow column, E, which forms the guide for the shank VF of a head, Gr. This head forms the bearings for the shaft II of the feed-roller I, and it is exposed to the action of a spring', J, which has a tendency to force the feed-roller up toward the gage-roller. A setscrew, a, Figs. l and 3, prevents the feedroller from rising beyond the desired point,

and it serves to adjust the distance between the feed-roller and the gage-roller.

The shaft II of the feed-roller is connected, by a universal joint, b, to a shaft, II', which has its bearing in a box, c, and which is geared together with the driving-shaftB bycog-wheels d c. The box c is secured to the frame A by a single screw-pivot, j', Fig. 2, so that it can turn thereon. The feed-roller, in being raised or lowered, must preserve its parallelism with the gage-roller, since its supporting-head G is guided in the vertical column E. But as the feed-roller is raised or lowered its shaft H is thrown out of line with the shaft H', and for this reason the universal joint b and the swivelbox c have to be applied. A screw, a', which extends through a slot in the head. G, and screws into the frame A, assists in preserving the parallelism of the feed-roller.

On the side of the frame A opposite to that of the feed-roller is situated the knife K, which is secured to a support, L. (See Figs. 2 and 3.) This support rests upon a bracket, M, and is held in position by a set-screw, g, which ex-- tends through a slot, h, Fig. 2, so that the knife can` be adjusted in the direction of the length of the gage-roller. The bracket M is secured to the frame A by a set-screw, f5, which extends through a slot, j, Fig. 2, so that the knife can be raised or lowered. y

The cutting-edge of the knife is curved upward at its inner end, (see Figs. l and 2,) and the diameter of the feed-roller is increased at its inner end to correspond to the curvature of the cutting-edge of the knife. The cuttingedge of the knife is made longer than the feedroller, so'that When Ythe Vknife is adjusted in the direction ofthe length of the .gage-roller itsouter end will' always extend beyond the g outer end of the feed-roller. )lose to the in ner ends ofthe gage-roller is Vsituated the ed ge- Vgage N, which assists in guiding the material during theoperation of splitting and bevelin 0'. rlhe.feed-roller is j n'ovidedwith teeth throughout its Whole length, so that the same takes a Vfirm hold. of the inaterialto be operated upon. Y

Afterthc `feed-roller has been adjusted at the desired distance from the gage-rollercor'-Y respondingto theV original thickness of theY material to be Vacted upomthe knifeis set ata distance from the gage-roller.corresponding to Vthe thickness which the Vmaterial is to have after it has been split, and Vthen the knifey is Vadjusted in the direction of the length of the gage-roller, sothatits curvedV edge coincidesV Y with the corner formed between the edge-gage andV thebottoni line of the'gage-roller. The

Vleather or other material, which is first Vcut upV into blanks of the desired shapegsuch, for in- -fstance, as'counters or boxes for boots and the handle G Ythe blank is split to the desired thickness, andV its inner edge is beveled off V(see Fig. Li) without leavinga deiicient ridge upon Vthe Vsurface of the blank, as is the caseV Y in machines using a straight Vknife or cutter.

z S After the blank has thus been split and beveled at one edge its oppositeedge is brought against the. edge .gage, and byy passing the blank through the machine the second time this inner edge is also beveled off to the desired shape. (See Fig. 5.) It Will be readily seen that this second operation could not be performed if the feed-roller Was made of uniform thickness throughout its entire length, since the blank is split by the first operation, so that Vthe parallel portion ot' the feed-roller would not feed it a second time. During the second operation the blank is fed by the action ot` the increased inner end of the feed-roller.

VThe form of the edge-gage must be changed Y for blanks of differentshapen Our :machine is designed particularly for splittingV and lieveling counters and boxes for boots and shoes; but it'ean beused forblanks V1What We claim as new, and Vdesire to secure byV Letters Patent, is-' of any other description made of leather, paste- Y Y board, or other Vmateriali of a similar nature.
