FABRIC STRIIPING 0R CUTTING MACHINE.

Specication of Letters Patent.

Patented Apr. 27, 1920.

Application led October 11, 1919. Serial No. 329,915.

T0 all whom it may concern v Be it known that I, ALICE `MAWBY BLAKESLEE, a citizen of the United States, residing at Philadel hia, in the county of Philadelphia and tate of Pennsylvania, have invented certain new and useful Improvements in Fabric Stripping or Cutting Machines, of which the following is a speciication, reference being had to the accompanying drawings.

This invention relates to a fabric stripping or cutting machine, and an object of the invention is the provision of amachine of this kind which is simple, eicient and practical in construction, and can be manufactured for a relatively low cost and sold at a reasonable profit. t

As another object of the invention it is the aim to vprovide a machine consisting of a suitable frame with means thereon for holding the fabric very flat and without wrinkling, and wherein means is afforded, on which the fabric may be fed to the fabric holding means, whereby the fabric may be subsequently evenly stripped or cut, after which the strips may be usedfor-various purposes. r

vA further object of the inventionv is the provision of a machine of this type particularly adapted for cutting or lstripping fabric, preferably rags, though not necessarily, and including a traveling belt on which the fabric is held by super-imposed means, including cutting or stripping means beyond the holding means, whereby just as the fabric or rags leave the holding means, it is evenly cut. f Y v A still further objectof the invention is the provision of an improvedV stripping means for the fabric or other like material comprising adjacent revoluble cylindrical surfaces provided with undulated cutting parts, between which the fabric or lthe. like passes, whereby it is cut into even strips.

As an additional object of the invention it is the aim to provide means intermediate the undulated cutting parts, to prevent the Vfabric or the like from slipping, and to maintain the same uniform, as it passes between the revoluble cylindrical faces of the cutting means. Furthermore as the fabric is stripped, and owing to the cutting parts being undulated, the fabric or the like is drawn taut in a transverse plane, thereby insuring e cutting action, Without tearing the fabric or other material,

While the design and construction at present illustrated and set forth is deemed preferable, it is obvious that as a result of a reduction of the invention to a moreV practical form for commercial purposes, the invention may be susceptible to changes, and the right to these changes is claimed, provided they are comprehended Within the sco e of what is claimed.

he invention comprises further features and combination of parts, as will be hereinafter set forth, shown in the drawings and claimed.

eferring more especially to the ldrawings l designates a base, on which the feet 2 of the legs 3 of upright standards 4 rest. These vstandards are reinforced relatively to each other by means of transversely disposed braces 5. Mounted in bearings of the upper parts of the standards are rotating shafts 6 and 7 arranged horizontally and spaced in parallelism, and keyed or feathered on the shafts as at 8 are rollers 9 and 10. These rollers 9 and l0 are substantially Ydisk shaped, and may be constructed preferably of metal, though not necessarily for it is obvious that they may be constructed of any other suitable material. If constructed of material other than metal, say for inr stance hardwood or the like, their cylindrical portions may be covered with metal bands (not shown) and which bands may have cutting parts. However, in thepresent instance it has been found more practi cal to construct the rollers 9 and 10 of metal, and they are arranged adj acent and vflat against each other and secured on the shafts in any suitable manner (not shown) so as to rotate with the shafts. Certain marginal corner edges of these rollers 9 and 10 are beveled outwardly and radially as indicated at 11, andare sharpened as shown at 12. Certain other corner edges of these rollers or disks are beveled inwardly and radially as indicated at 13. The faces of the rollers adjacent .the sharpenedA beveled marginal corner edges have annular grooves or channels 14, which are arranged to assume positions adjacent the annular grooves or channels' 15, as shown clearly in Fig'. 6. It will be noted that the rollers or disks of the shaft 6 have their sharpened beveled marginal corner edges assuming positions in staggered relation to the corresponding sharpened beveledjmarginal edges of the rollers of the lower shaft 7, so that when'the rollers of both shafts lare arranged as illustrated in Fig.V 6, undulated revoluble contacting surfaces are afforded, and furthermore the sharpened or cutting marginal corner edges of the super-imposed rollers will overlap and be arranged adjacent the y,corresponding sharpened edgesof the lower rollers or disks. The fabric, preferably rags, though not necessarily, is fed between the cutting rollers, so that it may be severed into elongated strips. The rollers 9 and 10 intermediate the beveled parts of the rollers have annular grooves or channels v15,

rwhich receive rings 16 of soft material, preferably rubber or the like. When the disks or rollers 9 and 10 as shown in Figs. 5.and 6 are arranged adjacent each other, thesoft or resilient rings 16 willbarely frictionally contact, and their adjacentfaces will act to feed the fabric between the'upper and lower series of rollers, Ythereby not* only holding the fabric flat and even, butiwill yactas means to prevent thefabric from-becoming jammed, or fed too rapidly. Furthermore owing to the undulated space between the Yrollers and through which the fabric passes, the fabric is stretched, and held taut, so as to facilitate the stripping l0r cutting action of the marginal cutting edges of the rollers. A shaft 17 is mounted in bearings 18 lof the standards or up- .'rights, and keyed or .otherwise secured upon the shaft 17 is a roller 19, and this serves as a means for throwing the rags or fabric away from the machine, when they drop upon it after being cut by the cutting rollers.

Mounted upon one end of the shaft 7 (which carries the lower series ofrollers or disks 10) is a pulley 20, which is engaged by a suitable vbelt I21,` which `in-turn passes about .apulley 22 of a shaft23. This shaft 23 is `mounted in suitable bearings 24,

`which vare disposed upon the lelongated base part 25. The shaft 23 may4 .be operated in any vsuitable manner and by any suitable source of power (not shown) so las. to furnish power to the .machine 28Ypasses- The belt 28 in turn `engages in the groove of the pulley 29, which is mounted upon one end of the shaft of the roller 19, so that power 'may be transmitted to said roller, so that thefabric 'or other material being stripped may be' thrown from the machine, so as to prevent the material or fabric from becoming entangled with parts of the mechanism.v

Also mounted upon the shaft 7 at one end thereof is a gear'29, which meshes with the gear 30. The gear 30 isispaced sufficiently from one of the faces'of the standards or uprights so `as toprovide a space for the admission of a gearV 31, whichis carr-ied by the upper shaft 6. Projecting from the standards or uprights of the frame arelsuitable side walls 32, which are parallel to each other.

VMounted in bearings of these sidesv are shafts Vshafts.- The end rollers of one shaftare engaged by an endless belt 37. It will be noted that the rollers 37 are super-imposed with relation to the -rollers 36, and are sufficiently spaced, to permit of ythe endless belt traveling betweenthe two series of rollers, so that when a piece of fabric, such as a rag or the like will be held flat and without wrinkling, when passing between the rollers. By holding the fabric or rag flat and even, preventing lateral lmovement thereof, the fabric or rag may be Vmore easily and quickly out, and at the same timeevenly cut, without tearingor ripping the fabric. f

One oftheV end shafts of the lowerlseries of rollers Vhas movable therewith a spur gear 38, which lmeshes with the-gear 31, so that when power is transmitted from the shaft l7, power in turn will be Vtransmitted to -the lower series of rollers 37. A,

AY bed plate 39 is securely mounted at 40 wardly Ythrough l the rollers -36V and 37, 'and by means of the belt vor other feed 37ftheV fabric or ragis caught and .carried forwardly in a flat position between-the belt Aand the rollers 36, until the fabric or rag `is'claimed asrnew and useful is 1. In a `machine as set forth, a framehaving an elongated bed, upper andlowerrevluble members lmounted yin ,bearings .of ,the

on the sides 32and is designed for' the sup Y lport of the fabric or rags-to be cut.` The `fabric or rags to be cut is placed upon the vbed plate, in a flat position, and is slid for- Y beveled in a direction from the soft resilient ring, the opposite annular corner portion of each upper roller being beveled inwardly on a plane corresponding tol the first bevel, the lower disk rollers being likewise beveled but reversely to the corresponding bevels of the upper disk rollers, whereby the radial faces of the corners which are beveled from the soft resilient rings of both sets of rollers may engage, thereby providing fabric severing means, the reversely arranged bevels of the upper and lower rollers forming spaces between the rollers, thereby acting to draw the fabric taut to insure severing of the fabric, and feed means mounted on said lateral bed for feeding the fabric between the severing roller's. Y

2. In a stripping machine as set forth, a frame having a lateral bed, of upper and lower revoluble severing elements having overlapping cutting edges and provided with beveled corners extending in correspending planes, thereby iforming spaces between the rollers which are staggered, therebyacting to strip the fabric to insure the severing of the fabric by the cutting edges, 'said upper and lower series of rollers having inlaid soft resilient rings acting to feed, stretch and hold taut the fabric as it passes between the rollers and feed means on the lateral bed for feeding the fabric between the severing rollers.

3. In a stripping machine as set forth, a frame having a lateral bed, upper and lower revoluble severing elements having coperatively engaged cutting parts provided with staggeredly arranged spaces positioned at intervals between the rollers, said upper and lower series of rollers having coperatively opposed, inlaid soft resilient rings alternately arranged with respect to the spaces and acting to feed, stretch and hold taut the fabric as it passes between the rollers, and feeding means on the lateral bed for feeding the fabric between the severing rollers.

In testimony whereof I hereunto afiix my signature.
