CUTTING-MACHINE.

Specification of Letters Patent. Patented NOV. 24, 1914.

Application filed January 13, 1913. Serial No. 741,806.

To all whom it may concern:

Be it known that I, ERAsTUs E. WINKLEY, a citizen of the United States, residingat Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Cutting-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skiled in the art to which it appertains to make and use the same.

The invention relates to machines for cutting sheet material. and its primary object is to provide a machine which is well adapted for cutting individual sheets from a continuous sheet or web` of rubber compound or similar plastic material as it comes from the calendering rolls.

To this end the invention contemplates the provision in a machine for cutting sheet material of a cutter which is `mounted to ltravel transversely7` across the moving stock,

andto also move forwardwith the stock t. while operating thereon so that the stock may be severed into individual sheets `without interrupting its forward movement.

In the preferred form of the invention the cutter is also so mounted and operated that after a cut is made it is moved idly back in a ,direction `opposite ,to that in which the Workis moving, preparatory to making its next transverse cutting movement.` The transverse cutting movements are also preferably made in opposite directions, since this t enables the cuts to be made in rapid succession, and reduces the distance through which the cutter moves with the work.

`In `addition `to the `features indicated above, the invention includes certain further features of construction and combinations of parts hereinafter described and set `forth in the claims.

The features of` the invention willbe `understood from an inspection` of the accompanyingl drawings, and the following detailed description of the machine illustrated therein. i. i

In the' drawings,Figure 1 is a rear elevation `of a cutting machine embodying the invention in its preferred form; Fig. 2 is a sectional elevation on line 2 4, Fig. 1, lookingin thedirection of the arrow 2; Fig. 3 is a plan view of the parts shown at the right in Fig. l; Fig. `4; is a sectional elevadirection of the arrow l; Fig. 5 is a partial rear elevation of the parts at the left of the drum in Fig. 1, the cutter carriage being shown at this end of the drum; Fig. 6 is a partial front elevation ofthe cutter carriage as shown in Fig. 1;.and Fig. 7 is a detailshowing one of the spring pressed pinsfor connecting the cutter support with the work supporting drum.

In the drawings` theinvention is shown as embodied ina machine especially de-` signed for cutting rubber stock as it comes from the calcndering rolls. As shown the continuous sheet of stock S is deliveredzfrom the rolls of the calendering machine on tov a traveling belt 1 from which it` passes on to a rotary work supporting drum 2 carried by a shaft 3. `The drum is driven from y the belt roll l through a sprocket chain 5" The cutter disk is journaled in a cutter l l carriage 7 mounted to reciprocate on two transverse guide rods 9 and 10` secured in the upper ends of two arms 12. The arms l2 are arranged at opposite ends ofthe drum 2, and are journaled on the drum shaft 3 so that the arms and guide rods form a cutter support which is mounted to move about theaxis of the drum. The cutter carriage ismoved on the guide rods 9 and 10 i through a reciprocating head 13 mounted on guide rods 14 and provided with a groove 15 engaged by a roll `1G on the carriage. The groove 15 extends in the direction of the feed so that the cutter` carriage may move with the stock as it is carried across the drum by the movement of the head `18. The head is moved back and forth on the rod 14: by a sprocket chain 17 connected to the head and supported on the

sprocket wheels

18 and 19. The wheel 19 is secured l to the upper end of a shaft 20, the lower end of which carries a pinion21 engaged by a rack 22. The rack is actuated at proper intervals tomove the head 13 and connected p cutter carriage across the drum 2 by a cam 23 secured to the shaft 3, and engaging a roll 24 on one arm of a bell crank lever 25, the other arm of which is connected by a link 26 with the ra'ck 22.

The cutter supporting frame is normal-ly held in retracted position with the roll 16 against the stop 27 at the end of the groove 15 by springs 28. The support is moved forward with the drum during the travel of the cutter carriage across the drum by one of a series of spring pressed pins which project from the ends of the drum into position to engage the arms 12. In the construction shown the length ofl the sheets cut from the stock is one-sixth the circumference of the drum, and there are therefore six of these pins, three pins 29 being mounted in one end ofthe drum, and the alternate three pins 30 being mounted in the opposite end of the drum. 4

Assuming that the parts are in the positions indicated in the mainviews `of the drawings, with one of the cutter bars 31 in line with the cutter `disk 6, and with one vof the pins 30 in engagement with the arm 12 of the cutter support, the operation of the machine is as follows. rihe cutter support is moved forward with the drum by the engagement of the pin 30 with the arm l2, and

y at the same time the cam 23 acts to move the cutter carriage across the drum so that the cutter disk travels along the cutter bar and severs the stock along a line at right angles tothe line of travel. As the cutter carriage completes its travel across the drum, a projection 32 on the carriage strikes the upper end of a lever 33 which is pivoted on the arm 12, and rocks the lever so that its lower end forces the pin 30 back into the drum, thus disengaging the pin from the arm 12 of the cutter support. The cutter support is immediately returned toits initial position by the springs 23, and remains in this position until the succeeding cutter bar 31 comes into line with the cutter disk, when one of the pins 29 engages the arm 12 of the vcutter support at the corresponding end of the drum 2 and again moves the cutter support forward with the arm. At the same time the cam 23 moves the cutter carriage back across the drum to the position indicated in Fig. 1. As the cutter carriage completes its movement in this direction, it engages the lever 33 at this end of the cutter support, and rocks it to disengage the pin 29 from the arm 12 of the cutter support when the cutter support is again returned to initial position preparatory to the succeeding cut. The levers 33 are held in normal position against stop pins 34 by springs 35, so that their lower ends are normally out of the path of the

pins

29 and 30. y

While it is preferred to employ the spebodied,

ciiic construction and arrangement of parts shown land described, it will be understood that this construction and arrangement is not essential to the broader features of the invention, but may be varied and modified without departing therefrom.
