rTo all whom it may concern.'

Be it known that l, HARRY BUBIN, a citi- Zen of the United States, residing at .Philadelphia, in the count).7 of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Winding and Cutting Cloth, of which the following is a specification.

The principal objects of the present invention are, first, to provide a machine for winding cloth or fabric into a roll and for subsequently cut-ting the roll into coiled or wound strips of any width and which shall be strong, durable, reliable and accurate; second, to provide accurate mechanism for relatively adjusting the roll of cloth or fabric and the cutting knife or cutter in order to easily and quickly cut the roll exactly at any required point or points; third, to provide a speed changing mechanism for winding at relatively low and easily controlled speed and for cutting at higher speed; fourth, to provide simple devices for quickly changing the cloth drive from the center to the end of the roll; and fifth, to provide for properly grinding the knife or cutter. @ther objects of the invention will appear from the following description, and the invention will be claimed at the end hereof after having been first explained in connection with the accompanying drawings, forming part hereof, and in which- Figure 1, is an elevational view, partly in section, of the front of a machine embodying features of the invention.

Figs. 2 and 3, are respectively, elevational views of the left and righthand ends of the machine. Y

Fig. 4, is a cross-sectional view drawn to an enlarged scale and illustrating means for driving from the center of the roll.

Fig. 5, is a face view of a chuck for driving from the end of the roll, and

Fig. 6, is a schematic sectional view illustrative of the winding operation.

In the drawings 1 and 2, are standards, as of metal, and they together with the table 3, and the three tie rods 4, 5 and 6, arranged at the apeXes of a triangle, constitute a rigid and strong frame for the working parts. 7, is a shaft revolubly mounted in bearings, shown as of the ball type, in the standard 2, and in an extension 8, of the standard 1, which extension is carried by the rods 4, 5 and 6. This shaft 7, is circumferentially grooved at 9, to provide clearance for the cutter 10, and is longitudinally provided with a greove having inclined walls 11 and 12, Fig. 4, for the dual purpose of driving and releasing, through a detachable rod 13a, the paper tube 13, upon which the fabric A, is wound and of acting as a keyway byl which a key, on the slidingV chuck 14, .is driven from the shaft 7. The chuck 14, is provided with radially disposed T-head slots 15, in which slide jaws havinflr radially disposed inturned pins 16, and toothed backs 17 (Fie. l) which coperate with spring'detents 11a, so that as the jaws are pushed inward they are auton'iatically latched, and the jaws can be moved outward by releasing the spring detents 17a. The portion 18, of the extension 8, can be pulled toward the left in Fig. 1, along the rod 5, thus disengaging dowel pins 19, from the extension 8, and also disengaging the shaft 7, so that the part 18, can be turned down to permit of the removal of work over the end of the shaft 7. 20, is a generally triangular plate slidable on the rods 4 and 6, apertured for the passage of the rod 5, and at its apeX engaging the chuck 14, in such a j way that the latter is free for rotation. The plate or traveler 20, is centrally provided with a nut 21 engaged by a screw 22, revolubly mounted between the standards 1 and 2, and turned in either direction by a handwheel 28, at the front of the machine and near Ythe lefthand end thereof, through the intervention of a hand-wheel shaft24, and bevel gears 25. Loose on the shaft 7, are two driven clutch-members 26 and 27, of which either coperates with a third clutch member 28, splined for endwise motion on the shaft 7, and shifted by a-shipper 29 (Fig. 3), the purpose being to provide for driving the shaft 7, at two different speeds, one appropriate for winding and the other appropriate for cutting. To drive the shaft 7, for winding, use is made of the clutch member 27 driven by a sprocket chain 30, from friction clutch element 31, operated from Vpulley 32, and controlled from pedal 33,'through sliding rod 34, connected with the pedal' and with the friction clutch element 31, so that by operating the pedal the clutch lelement 31, may be more or less tightlyheld up to the pulley clutch element 82, and in this way the operator has control of the rotation of the shaft 7, and may instantly stop such rotation. shaft 7, for cutting, use is made of the To drive the clutch member 26, driven by a sprocket chain 35', from the hub 36,'Afast with the pulley 37, onto which the motor belt 38, is shifted by the belt shipper 39, operatable from the lefthand end of the machine. The shaft 40, of the cutter 10, is journaled ,in a swinging frame consisting of two shaft carrying arms 41 and an operatin handle 42, and mounted on the rod 5. r he Vcutter or circular knife 10, is alined with the notch 9, in the shaft 7, and the movement of the cutter away from the shaft is limited by the adjustable stop 43 (Fig. 2) on the inner 'face of the standardfl. The cutter and its shaft are driven by the chain and sprocket wheels 44 and 45 (Fig. 3) of which 45, is mounted on the rod 5, and driven by a sprocket wheel 46, fast to it and in turn Vdriven by a sprocket chain and wheel 47,

from the clutch member 26. 4S, is a grinder having its shaft journaled in a. bracket 49,

.carried by the'frame of the machine and driven by a sprocket chain and wheels 59, from a shaft 51, carried by brackets 52a, and driven from a toothed wheel 52, arranged on the hub 36, and meshing with a toothed wheel 53, having sprocket chain and wheel connection 54, Fig. 3, with it, thus the rims of the grinder and of the cutter run in the same direction at the point of contact, while the rims of the roll of fabric and cutter run in opposite directions at the point of contact. 55, is a tension device arranged on the table 3, and consisting of a fixed and a swinging member provided with rods ar ranged out of alinement with each other.

To wind a fabric into a roll, a paper tube 13, is put over the shaft 7, with a wire or rod 13a, between and in the groove 11-12. For this purpose the movable part 18, is swung clear of the lefthand end of the shaft 7 The handle 29, is moved to drive the shaft 7, from the clutch element27, and its accessories at a comparatively low speed, and the shipper 39, is moved to drive the pulley 32, from the motor. The fabric is led under rod 4, over the table 3, through the tension device 55, past the rods 6 and 5, and iswound on the tube 13. The winding operation is controlled by the pedal 33, which can be operated to stop it at any moment. To cut the wound fabric into strips the wire 13a, is withdrawn, the chuck jams are pushed in so that the pins 16, take into the wound roll of cloth and the belt shipper 39, is moved to apply power to the pulley 37, from which the cutter 10, and grinder 48, are driven, as has been described. The hand wheel 23, is turned to feed the roll to the left with a positive feed and to accurately position it in respect to the cutter 10, and for this pur pose reference may be made to the 'gage 56, carried by the rod 5. The handle 42, is manipulated to swing the cutter carrying frame and cause the cutter to cut the roll of at low speed, a chuck slidable on the shaft Y and splined to said groove and provided with fingers for driving the tube from the chuck at high speed in the Vabsence of the rod,

means for sliding the chuck and tube on the shaft, and a rotary cutter, substantially as described.

2. In a machine of the type recited the vcombination of a rotatable shaft for fabric,

a rotatable cutter shaft having a sprocket wheel, a grinder shaft having a sprocket wheel, a driving element having a sprocket wheel and a toothed gear wheel, a fabric shaft driving element having a pair of sprocket wheels, an intermediate toothed wheel meshing with said toothed gear-wheel, a sprocket chain between the sprocket wheel of the driving element and one of the sprocket wheels of the fabric shaft driving element, a sprocket gear including a pair of connected sprocket wheels, a sprocket chain from one of the last mentioned wheels to a sprocket wheel of the fabric shaft driving element 'and a sprocket chain from the other of the last mentioned wheels to the sprocket wheel of the cutter shaft, and a sprocket chain from the intermediate tooth wheel to the sprocket wheel of the grinder shaft, substantially as described. Y

In a machine of the type recited the combination of a pair of standards, three parallel rods arranged at the apeXes of a `triangle and connecting said standards and of which the bottom two are disposed side by side, an endwise immovable swinging frame mounted on the top rod and provided with a cutter, a traveler slidable on the horizontally spaced bottom rods and apertured for the passage of the top rod and provided with a rotatable clutch, a feed screw turnable on the standards and engaging a nut provided on the traveler to shift the latter in respect to the critter, and a hand wheel for turning the screw, substantiallyY as described.
