Referring to the drawings wherein like numerals. designate like parts, it can be seen thatnumeral 5 represents a base which has the upright 6 thereon. This uprightfi is provided with a shelf 7 and an intermediate portion thereof for supporting the electric motor 8 and with a second shelf 9.1ocated at itsupper end for supporting the (is electric motor 10. Y e

Numeral 11 represents a bearing supported upon thebase 5 and through this is journalled the shaft 12. At one end of this shaft 12 the same extends into. the tubular extension 13 which forms a shaft carrying the elongated pulley drum 14. Pulleys 15, 16 and 1'7 areprovided on this shaft 13. At the intermediate portion of the shaft 12 is a large pulley 18,}while at the opposite end of the shaft 12 from the shaft 13 is a universal unit, consisting of the frusto-cone 19 disposed against thecollar 20 at one end (the smallest end) rest-v ing on the ball bearing mountZl at its opposite end. This ball bearing mount 211s interposed betweenthe abutting end ofthe cone 19 and the s1eeve22 which sleeve is provided withthe shoulder 23. thereon disposed in a direction intersecting. the longitudinal axis of theuniversal unit oblique- 1y 'forthe purpose of feeding the material which is supportedby the cone; 19 and partly by the cylinder 2e to a position-:under the rotary knife 25; driven by the aforementioned motor 8. The sleeve 22 is provided withla slot 26 extending circumferentially for about half the distance around the blade toreceive the flexible needle, brass or like material designated by numerals 2"I,so that the same will project to swing a distance beyond the periphery of the sleeve 22 when extended in the position shown in-Figure 3.; p 1,

The needles 27 project from the glass disk 28 through a .leather jacket 29 surrounding the periphery o f the disk 28, and obviously can easily pass within the space between the sleeve and the jacket 29 as shown'onthe right in Figure 13. A belt 30 is employed to feed the cloth into the blade 25. 'This belt 30 isdriven by the pulley 31 and operates looselyoverthe stationary cylinder 19. This cylinder. forms a cover holding the fiber shoe which the b1ade 25 cutsinto; The sleeve 19 is operated by the shaft 12, the. cloth being pushed up on the cylinderby hand from the cylinder 24, until it comes in contact with the belt 30. The belt then feeds thecloth into the blade 25, whereupon the strip which has been cut is pulled away from the blade 25 by the needles 2'?- in such a way that the cloth strip can be pickedup by hand and the wind started around the reel 50. (While this hand operation is being accomplished, the machine is momentarily stopped.) When the cloth striphas been placed around the reel 59, the ma chine is put into gear and the remainder of the cloth is cut and wound up on the spool.

The aforementioned cylinder 24 is hollow to receive the collar 20 of the universal unit and the cylinder 24 is supported upon the head 32 carried by the rod 33 which projects from the bearing 34. The bearing 34 is stationary and forms a support that is bolted to the machine. The same supports the cylinder 24, the latter being the member over which the cloth is pulled before being cut. At the inner end of the cylinder 24 are inwardly projecting lugs 3535 which are engaged by the catches 36 on the collar 20 to prevent displacement of the cylinder 24 from the collar and from associationwith the -aforemen-, tioned universal unit.

The shaft 37 which supports not only the pulley 31, but the pulley 38 also, is in turn supported by the standards 39 and 40, suitably secured to the aforementioned base 5. Crossed belts 41 are trained over the pulleys l7 and 38 as shown in Figure 3, while the small pulley 42 on the shaft 43 has a belt 44 trained thereover and. over the large pulley 18, whereby the shaft 12 is driven bythe shaft 43, while the aforementioned shaft 37 is driven by the shaft 12. The shaft 43 is driven by a belt 45 trained over the pulley 46 on the armature shaft of the motor 10 and over the large pulley wheel 47 on the aforementioned shaft 43. The pulleys 47 and 44 with the shaft 43 are supported by the standard 48. I

A reel 50 is carried by the shaft 51, and one end portion of said shaft is pointed as at 52, to facilitate engagement of the reel on the shaft 51, while numeral 52 represents a'small pulley wheel. Numeral 53 (see Fig. 6) represents a collar to which the L-shaped part 54 is secured. This arm 54 at its outer laterally disposed end is provided with a head 55 alined with one of the ends of the T-shapedmember 56. The other end of the T- shaped member is alined with the head 57 of the outer end of the L-shaped arm 58 which is secured to the end of the shaft 51 opposite to the end supporting the reel 50. This winding mechanism is mounted by a suitable bracket to the base.

Adjacent to the shaft 51 are the bearings 59-59 for journally receivingthe internally threaded sleeve 60 on which the pulleys 61 and 62 are freely rotatable, each being provided at its inner side with a pair of diametrically oppositely located teeth 63; r

Mountable on the sleeve 60 and between the pulleys 61 and 62 and splined to the sleeve 60 as at 64, is a spool 65 having end circumferential flanges 66 and 67. The outer side of each of these flanges is provided with a pair of diametrically oppositely located teeth 68. .As is clearly shown in Figure 6, the inner end of the T-shaped member 56 engages between the flanges 66 and 67 as at 69, (see Fig. 6) while guides 70 are providedfor the two end'portions of the two members located outwardly of the spool 65.]Guides 70 obviously maintain the outer ends of the T-shaped member .alined with'the arms 54 and 58. An elongated shaft 71 is provided with threads 72 threadedly disposed through the sleeve 60 and this shaft 71 is provided with a longitudinally extending slot 73 therein into which engages the key 74 on the bear ing 59, thus preventing the shaft 71 from rotating. The ends of the shaft 71 are secured to the arm 54 and the arm 58.

An endless belt 75 is trained over the pulleys 62 and 16 (see Figure 1) while a crossed belt 76 is trained over the aforementioned pulleys 61 and 15 (see Figure l).

Trained over the drum 14 and the small pulley 52 on the shaft 51 is a belt 77, the belt 77 obviously being able to travel along the drum 14 as the shaft 51 and its pulley 52 travels back and forth. The drum 14, belt 77 and pulley 52 afford drive means for the reel 50. The cloth to be cut is in tubular form. This tube of course is pushed up on the cylinder 24 by hand over the cone 19 until it comes in contact with the belt 30. As can be seen by the drawings (Fig. 3), this belt 30 is pulled by the pulley 31, the pulley 31 being driven by the shaft 37 which in turn is driven by the pulley 38. As is seen in Fig. 3, this shaft 37 is placed at an angle across the machine which angle causes the belt 30 to run across the sleeve 23 at the same angle so that when the belt 30 feeds the cloth into the blade 25, it starts at an angle causing. the cloth to be cut in ribbon-like strips. When the machine is in gear and cylinder 24 is pushed in contact with the cone 19, the collar 20 is caused to turn with the sleeve by means of the catches 36. All the while the machine is operating and cutting the cloth, the cylinder 24 is turning with the cloth thereon at the same speed as the rest of the machine. The needles 27 pull the cut ribbon-like strip away from the blade 25 so that it can be picked up by hand and started around the spool 50.

It can now be seen, that by moving the cylinder 24 apart from the collar 20, the tubular textile material can be placed thereon after the cylinder 24 has been attached to the collar 20. The materials now in position and by engaging the same against the inner side of the belt 30 and then starting the two motors, the material, with the assistance of the belt 30 and the needles 27 will be fed under the knife 25 and by fastening the starting end of the material to the reel 50, the cut material can be uniformly wound on the reel, by the operation of the feeding mechanism hereinbefore clearly described. The width of the stock is three-fourths of an inch more or less.

It will be observed that when the reel has reached one extreme of travel, the head 55 or head 57 will engage one outer end of the T- shaped member 56 and this will obviously grip the spool 65, (see Figure 4) so that its teeth 68 will disengage from the teeth'of one pulley 61 or 62; to engage with the teeth of the other pulley so that the drive will be changed from the parallel belt 75 to the crossed belt 76 thus reversing the drive motion between the shaft 13 and internally threaded sleeve 60, which feeds shaft 71 longitudinally. In regard to the belt drives, it can be seen that the motor 10 by way of the pulleys 46 and 47 and belt 45 drive the pulley 42. The pulley 18 on the shaft 12 has the aforementioned pulley 42 and the belt 44 trained over the same. On the shaft and driven by the pulley 18 is the pulley 17 and this drives the pulley 38 by way of the belt 41. Thus power is supplied to the shaft 37 which also carries the pulley 31. Trained over the pulley 31 and sleeve 22 is the belt 30. In this manner, power is supplied to operate the cone 19 of the fabric feeder. As is clearly shown in Fig. 1, a belt 75 is trained over the pulleys -l6'and 62 and has its flights parallel, while trained over the pulleys 61 and 15 is a belt 76 whose flights are crossed to secure reverse motion. v

While the foregoingspecification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size, and materials may be resorted to without departing from the spirit or scope of the invention as claimed hereinafter.

Having thus described my invention, what I claim as new is: i

1. In a textile cutting machine, a material supporting cylinder, a belt, a rotary knife adjacent the cylinder and belt between which and the cylinder textile material engages to be fed from the cylinder to a position where the same cylinder, and a belt for feeding the material from the cylinder to a position where the same can be cut by the knife, and a reel on to which the cut material can be wound, and. means for reciprocating the reel whereby the material can be uniformly wound thereon, a motor, said motor being adapted to drive both the reel and the belt.

4. In a textile cutting machine, a material supporting cylinder, a rotary knife adjacent the cylinder, and a belt for feeding the material from the cylinder to a position where the same can be cut by the knife, the cylinder being provided with a circumferentially extending slot therein, a shaft passing into the cylinder, 9/ disk on the last mentioned shaft, and flexible teeth on the periphery of the disk projectible through the slot for engaging the material on the cylinder to feed the same to the knife.
