IMPROVEMENT IN SEAMINGAND RAG-CUTTING MACHINE.

TO ALL WHOM IT MAY CONCERN Be it known that we, Jenn Conil-rs, Jr., and NICHOLAS It. Nixon, both of Richmond, inthe county of Wayne,

and State of Indiana, have invented a certain new and useful-Machine for Cutting-Bags; and we do herebyV declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making part of this specification,4 in which- Figure-1 is a perspective view.

Figure 2 is a longitudinal elevation.-

Figure 3 is the roller B,- showing the positions of the two belts H and I, and of the belts Gr and F F.

Heretofore, the operation of cutting rags intended to be made into shoddy, paper, or carpets, that is, of cutting oif the seams Qr other refuse from rags intended for shoddy or ne white paper, and of cutting the rags into strips for tho purpose of being woven into carpets, 'was a slow andA tedious one, requiring to be done by hand with a pair of ordinary scissors.l

The object of our invention is to seam rags to be manufactured into shoddy and ine white paper, and to cut rags into "uniformlstrips for the purpose of being woven into carpets, in much less time, and to cut them more uniformly than they were heretofore cut.

Tovenable those skilled in the-art to make and use our invention, we will proceed to describe its operation and construction with reference to the drawings.

Similar letters of reference refer to similar parts of our machine in the different drawings.'

' A A A is the framework, on which our machine is constructed. B B is a roller, parallel to another roller,

C O. D D is a roller, parallel to another roller, E E. The roller B B is also parallel with the roller D D, and the rollerO C is also parallel with the roller E E. F F is a continuous or endless belt, running around'the rollers BB and D D, and G G is another continuous or endless belt, running around `the same rollers. H is another continuous or endless. belt, running underneath the belt G Gr, and around the under rollers C C and E E. I isstill another continuous or endless beltrunning underneath the belt F F, and also around the under rollers C C and E E. The rollers' are each made like the roller B B, fig. 3. L L is an arbor or shaft,grunning in journal-boxes attached to the frame, on which is'attached the cutter or knife K K, so that it is perpendicular to the surface of the belts, as shown in iig. 1. This cutter or knife is fastened on such part of the said arbor that it passes between the lower edges of the belts G -Cr and F F, and also between the upper edges' of the belts H und I. The space between the belts G Gr and F F is the same as that betweenthe belts` .ITI and I, that space heingjust suiiicient for the knife or cutter K Kto work in freely, without impinging on any of said belts. The knife, shown in the drawings, and most distinctly Vseen at`ig. 2, is a plane and circular plate, or" such size that when properly -iixed in the machine it shall not extendfahove the belts F F and G G, nor belowvthe belts H H and I, but yet may be as large as possible within those limits. Said knife has ynotches cut into it, and extend ing down nearly to the arbor, of about the shape of triangles, having six teeth, as shown at M M M, ig. 2,-

which have 'sharp edges on the sides that strike the cloth. The power is applied to the machine at the smallI pulley r, on the shaft L L. and from thence, by means of a belt, .which is twisted, to give a reverse motion, applied on the drum g, is conveyed to the large drum P. When power is applied to the drum P, it turns the roller E E, and, by means oi`cogwheels an, turns theroller D Din a. reverse direction, and by thismeans the upper portion of the belt I runs in the same direction as the lower portion of its .parallel belt, F F, andthe upper portion of the belt II in the same directionias the lower portion of the belt G Cr, and each .pair of said parallel belts will carry along between them the rags to be fed tothe cutter or knife. l The journal-boxes, in

which the rollers B B, CC, D D, and E E run, are adjustable, and the cogs n n maybe of larger or smaller size, Iso that the distance between Athe rollers B B and C C, and also between the rollers D-D and E E, may-be' increased or diminished, so as t'o permit thicker or thinner rags, or a greater or less number of thicknesses of rags, to be fed into the machine. i

' When power is thus applied te the pulley o, and-from thence, as before described,- to the drum I), and from there to ali of said belts, the machine is then in motion, and ready-to perform its intended functions. The rags ure then fed into the machine by putting,` them betweenthe upper sides of the lower belts H and I and the und-er sides of the upper belts G G and F F, in suchmanner that the parts Vof the rags which it is desired `to cut of as refuse shall pass between lthe be'lts G G end H, and the part'of the rags which it is intended to use in the manufacture of paper, shoddy, or carpet, shall pues between the other twobelts, towit, F F and The rags will be fed into that end of the machine from which the motion respectively of the upper andvunder parts of the belts will carry .them into the machine, and as they pass through the machine,rcstin1aT on und supported by the upper surfaces of the lower belts H and I, and held with sucient firmness in their places by the under surfaces of the upper belts G G and F F, the cutter or` knives, running in the linebetwecn the-belts F F and G G, and between the belts H and I., divides or cuts the rags fed into the machine through that line, andthe belts carry the rags thus cut completely through and clear of' the machin, the refuse being carried bythe belts G G und H, andthe other portion of therags being carried by the belts F F und H.

The drawings hereto annexed, und also the above description, refer exclusively to a machine for cutting but one strip at n time, and being adapted to cutting off the refuse portions of the rags, but it is evident that the principle of our invention applies ns well to cuttingr e. number ot` uniform strips at the same time, useful for weaving into carpets. -In'order that theA ina-chine above represented and described may be adapted for the -cuttinr of rags into uniform strips, series of knives, similar to the cutter K K, and parallel to each otherthey may be upon the sume shat`t-must be used, and between each two knives of Athis series .there must be two belts, an upper and lower one, like those represented in the drawing, tig.' 1, except in size," which must bev the same as that of the strips intended to be cut. The4 spaces between the belts to be the same, and for the reasons before describedx. The usual size of such strips for carpet-weaving is about three-eighths of an. inch in Width,'but that size is varied by the thickness of the cloth, and other causes known to those skilled in the art. There may be eight knives in the seid series, or the number muy be varied to suit the necessity or convenience of the operator. It' is not important, as far as the principle of our inventionis concerned, how many knives are used. I

I Having thus described our invention, what we claim, anddesire to secure by Letters Patent, is-

1. The combination of the belts FF, G G, H H, and and their supporting rollers, as and forthe pur poses shown and described. I

2.V The cuttersK K, arranged and operating between the belts, substantially in 'the manner und for the purpose specified.

3. We claim a series of knives or cutters in combination withalternate double belts, substantially in the manner described, for the purpose of cutting rags into strips of any desirable width7 to be woven into carpets.
