SPECIFICATION forming part of Letters Patent No. 622,906, dated April 11, 1899.

Application filed May 20,1898. Serial No. 681,193. (No model.) i

To all whom it may concern.-

Be it known that I, NELSON M. WATSON, a

citizen of the United States, residing at Detroit, county of WVayne, State of Michigan, have invented a certain new and useful Improvement in Cutters for Cutting Metallic Packing; and I 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 appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification. My invention has for its object a novel cutter for cutting metallic packing; and it consists of the-devices hereinafter described and claimed, and'illustrated in the accompanying drawings, in which' Figure 1 is a view in side elevation, showing parts of a lathe with my improved cutter attached thereto and in position to cut a strip of metallic packing from a metal disk or cylinder. Fig. 2 is a detail view in perspective ofthe cutter. Fig. 3 is a view in section on the line 3 3, Fig. 2.

My invention is designed to provide a cutter to cut a metallic packing formed of long, continuous, flat, and narrow strips of antifriction metal, a desired number of such strips being assembled in a rope form to constitute a packin g for various purposes, also to form gaskets and for analogous uses. For this purpose my invention contemplates a cutter for cutting a long continuous strip of antifriction or other metal from a disk or cylinder, the cutter being arranged to feed straight inward toward the center of said disk or cylinder, so as to cut the strips in a long continuous fiat form.

It will be obvious that if the cutter traveled horizontally across the disk or cylinder it would cut a strip or shavingwhich would curl or coil, and which I aim to prevent, and to secure the individual strips for the packing, as heretofore stated, in a long flat conshaft A. Upon the shaft of the gear E is a bevel-gear E, meshing with a bevel-gear D upon the Worm D. By this construction it will be apparent that as the disk or cylinder A rotates the worm will rotate correspondingly and cause a corresponding travel of the cutter inward toward the center of said disk or cylinder.

My improved cutter is formed with any suitable body, (indicated at B,) having a suitable cutter-blade B secured thereupon. The cutter-body may be provided with an arm B whereby the cutter is engaged upon the support C. The cutter-blade B may be secured in place by means of a bolt 1). The cutter body is provided with a flange or shoulder (indicated at b) adjacent to one edge of the blade B but leaving a channel (indicated at 71 between said shoulder and the adjacent edge of the cutter-blade, through which the strip a, which has been cut by the edge of the cutter-blade, may pass, the shoulder Z2 guiding the strip through said channel and upon a reel or other suitable device for carryin g the strip. The shoulder 19 preferably projects over the upper edge of the blade 13 as shown. The body B of the cutter is preferably constructed with an elongated orifice at b as indicated in dotted lines in Fig. 2, so that the blade may be adjusted to compensate for any wear in grinding and so that the cutting edge of the blade may be set or adjusted as required. The channel 1) preferably projects rearward from the cutting edge of the blade longitudinally of the blade for a suitable distance, as in Fig. 2, the channel then projecting upward, as shown..

I would have it understood that I do not limit myself to any special means-forrotating the disk or cylinder A or for advancing the cutter B to the work directly toward the center of the disk or cylinder. The cutter Ico may be held in the support in any suitable manner, as by a screw 0 the disk, thereby cutting a coiled or convoluted strip. It will be readily understood that the channel 19 is in the nature of a guidechannel through which the strip is directed after being out from the disk. The body is recessed on one of its faces, as shown at b, to receive the cutter-blade, said recesses being extended laterally at one side of the blade to communicate with the channel o The gear E may be driven from any suitable source of power.

The recess b of the body of the cutter extends longitudinally of said body, as well as the cutter-blade located therein, while the channel also projects rearwardlylongitudinally of the cutter-bod y and parallel with the upper lateral edge of the cutter-blade. I do not, however, claim as new the mechanism for operating t-hecutter.

What I claim as my invention is 1.- A cutter for the purpose described, having in combination a body recessed upon one of its lateral faces,longitudinally of said body, and a cutter-blade engaged in said recess longitudinally of said body, said body provided with an additional guide-channel adjacent to one of the marginal edges of said blade upon the same face thereof as said recess through which a shaving orstrip severed by the cutterblade may pass, and with a flange or shoulder adjacent to said guide-channel, said flange or shoulder projecting over the adjacent edge of the blade, said guide-channel communicating with said recess at its forward end and extending at right angles, to the cutting edge of the blade parallel with one of the marginal edges of the blade from the cutting edge of the blade rearward longitudinally of the body and then opening upward through said body, substantially as set forth.

2. A cutterfor the purpose described, having in combination a body provided with a recess 12 longitudinally of said body to receive a cutter-blade, and constructed to be secured to a suitable support, and a cutter-blade engaged in said recess longitudinally of said and opening in an upward direction through said body, substantially as set forth.

In testimony whereof I sign this specification in the presence of two witnesses.
