THOMAS F. HICKEY, OF SHREWSBURY, MASSACHUSETTS.
. v LEATHER-CUTTING MACHINE.
Application filed. May 29,"
fl '0 all whom it may concern Be it known that I, THOMAS F. HICKEY, a citizen of the United States, residing at Shrewsbury, in the county of WVorcester and State of Massachusetts, have invented a new and useful Leather-Cutting Machine, of which the following is a specification.
This invention relates to a machinefor cutting sheets of leather into strips of medium width. In a prior application, Serial No. 289,464, filed April 11, 1919, I have shown a machine for cutting leather into narrow strips, which is very effective for the purpose specified, but which is not adapted for cutting wider strips, as the leather will buckle and bulge as it passes through the rolls and uneven edges will result.
It is the object of my present invention to provide a machine which will cut leather. into strips of even width, having straight and uniform edges and which will perform this operation easily and rapidly.
\Vith this general object in view, my invention relates to certain arrangements and combinations of parts which will be herein after described, and more particularly pointed out in the appended claim. Y
A preferred form of my invention is shown in the drawings in which-- Figure 1 is a plan view of my improved machine:
Fig. 2 is a side elevation thereof;
Fig. 3 is an end elevation, and
Fig. 4 is a sectional elevation taken along the line 44 in Fig. 1.
Referring to the drawings, my improved machine comprises a frame 10 provided with bearings 11 and 12 for a cutting shaft 13, on which a plurality of cutting disks 14 are mounted in spaced relation, being'separated by collars 15. Tight and loose pulleys 16 and 17 are also mounted on the shaft 13.
A shaft 18 ismounted above the cutting shaft Band is rotatable in bearings 19 and 20, adjustable in the frame 10 and yieldin ly supported by compression springs 21. djusting screws 22 regulate the distance between the shaft 18 and the cutting shaft 13. The shaft 18 is provided with grooves 23 Specification of Letters Patent.

cooperating with the cutting disks 14. The
or between collars on the shaft 18 adapted to be spaced to-correspond to the spacing of the cutting disks; A guide flange 24 may also be provided at oneend of the shaft 18. The shafts 18 and 13 are connected by'gears 25 and 26 through which the shaft 18 is driven.
speed of the feed rolls is somewhat less than the surface speed of the shaft 18. and the disks 14.
A table 34 may be provided for support- .ing the stock as it is fed to the rolls 27 and 28, and this table may be provided with a guide 35 alined with the flange 24. A second table 36 may also be provided to receive the stock as it leaves the cutting disks 14. The shaft 18 is ordinarily so adjusted that the grooved collars thereon exert no pressure upon the stock S, as the stock passes over the collars on the cutting shaft, but merely cooperate with the disks 14 in performing the cutting operation.
The relatively slow speed of the feed rolls is a very important feature of my invention,
and contributes largely to the successful operation ofthe machine. I I
Having thus described my invention, it will be evident that changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope thereof as set forth in the claim,
and I do not wish to be otherwise limited to the details herein disclosed, but What I claim 1s A leather cutting machine comprising a cutting shaft having a series of spaced disk knives thereon, a grooved shaft cooperating with said kni'ves, a pair of feed rolls spaced from said shafts and engaging the stock as it approaches the knives, and means to face speed.
In testimony whereof I have hereunto at fi Xed my signature.
