CLOTH-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 562,657, dated June 23, 1896.

.Application filed August 9, 1895.

To all wiz/0m zit may concern,.-

Be it known that I, JACOB PHILirPsoHN, a subject of the King` of Prussia, German Emperor, and a resident of Berlin, in the Kingdom of Prussia, German Empire, have invented a new and useful Improved Cloth-Cutting Apparatus, of which the following is an exact specicaton.

This invention refers to cloth-cutting 1nachines in which a nu mber of superposed layers of stuff is cut by means of a rotary cutter. My improvements in machines of said sort relate to the combination of said rotary cutter with a vcrtically-reciprocatin g cutter having its cutting edge on its lower end. This reciprocating cutter is arranged adjacent to the rotary cutter and moves in a plane parallel to the plane of rotation of said rotary cutter.

The purpose of my improvements is to do away with the necessity of raising the layer of stu against the vertical front portion of the rotary cutter at the end of each cut, and to effect in lieu thereof the cutting of the remaining uncut portions (which, in consequence of the circular shape of the rotary cutter, increase in length from the top layer to the bottom layers) by means of said second cutter.

In order to make myinventicn more clear, I refer to the accompanying drawings,in which similar letters denote similar part-s throughout the different views, and in which- Figure l is a front view of my improved cloth-cutting apparatus. Fig. 2 is a vertical section through the same and showing the lefthand portion thereof; and Fig. 3 is an outer view of a portion of the handle, also seen from the right-hand side with regard to Fig. l.

The tube a, which connects the upper casing a' with the lower casin g a2, embraces a ring l), furnished with an inner flange t. Said flange takes into a corresponding groove of a sleeve c, carrying at its upper end the bevelwheel d, and at its lower end the bevel-wheel e. The sleeve o may be displaced upon the shaft f, with which it is connected by feather and groove. For that purpose the ring b is furnished with apin Z9, which takes through a cut-out a3 of Z-like configuration provided in the tube a and the handle g. Owing to the special configuration of said cut-out, the pin b2, and with it the sleeve c, with its two bevel-wheels, may be adjusted and fixed in two positions.

Serial No. 558,750. (No model.)

If the ring t is in the position shown in the drawings, the bevel-wheel e gears with a similar wheel t', secured to the shaft la. The latter carries, moreover, a cog-wheel Z, which is in gear with a cog-wheel m, ixed to the shaft n. This shaft projects through the front wall of the casing a2, and operates the rotary cutter o. If, however, the sleeve c is in its upper position, the bevel-wheel d gears with a similar Wheel p, fixed to the shaft q. The latter carries at its front end the crank disk fr', which is connected with the lever s by the connecting-rod 2f. Said lever is at one end hinged to the link u, attached to the cap 0 for the rotary cutter, and is at the other end connected with the vertically-reciprocating cutter o, which latter is arranged within a guide w, hinged to a projecting arm a: of the casing a. The pin or bolt connecting the lever s with the verticaily-reciprocating cut ter o passes through a slot of the guide uf. It will thus be seen that there is a coupling established either between the bevel-wheels e and i, or between the bevel-wheels d and p, and that there is operated in the first case the rotary or main cutter o, and in the second case the reciprocating or auxiliary knife r.

As the shaft f does not cease rotating during the shifting of the sleeve c, there is a possibilty that the teeth of one or the other pair of wheels may get broken on coming in contact with each other. In order to obviate such an occurrence, I have devised the following arrangement:

The naves of the bevel-wheels in question are furnished with frictional disks p', d', e', and i', respectively, one or the other pair of which comes on the displacement of the sleeve c in contact prior to the contact between the respective bevel-wheels, and the bevel-wheels to be driven are thus caused to rotate before said latter contact occurs. The frictional disks to be driven are, as a matter of course, of greater diameter than the driving-disks, and the rotation of the former commences thus with a comparatively slow velocity, but becomes quickly faster and faster on the growing approach of the respective two bevelwheels. In a short time the rotary velocity of these two wheels is exactly the same, and they may then be brought into gear with each other Without any fear of break.

The frictional disks need not indispensably be fixed to, or made integrally with, the naves IOO of the bevelwheels, but may be loosely arranged upon said naves, and combinedy with a loose or fast india-rubber disk, such as 2, supported by an auxiliary frictional disk The latter is firmly connected with the nave of the respective bevel-wheel, and, further, the frictional surface of the disks p', dac., need not be perfectly even, but may have an annular groove, such as p2, annihilating the friction as soon as the respective bevel-wheels are in proper gear.

Having thus fully described the nature of this invention, what I desire to secure by Letters Patent of the United States isl. In a cloth-cutting machine, theco1nbination with the rotary cutter, and means for operating the same, of a vertically-reciprocating cutter having its cuttingr edge on its lower end; such reciprocating cutter being adjacent to, and moving in a plane parallel to the plane of rotation of the rotary cutter, and means for operating such reciprocating cutter independently of the rotary cutter, as set forth.
