ABLON LITTLEFIELD, OF PROVIDENCE, RHODE ISLAND, ASSIGNOR TO NEW ENGLAND BUTT COMPANY, OF PROVIDENCE, RHODE ISLAND, A CORPORATION OF RHODE ISLAND.
CARRIER FOR BRAIDING-MACHINES.
Patented Jan. 12', 1915.
Application filed March 12, 1814. Serial No. 824,237.
To all whom it may concern Be it known that I, ARLON LITTLEFIELD, a citizen of the United States, and resident of the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Carriers for Braiding-Machines, of
provide a stop motion actuator and means 1n the tension arm for controlling the position of said actuator.
The invention further contemplates the providing of means in said stop motion actuator whereby it may be caused to engage the stop motion and stop the machine whether the carrier be running either to the left or to the right.
With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the ap ended claims.
' 8f the accompanying drawing: Figure 1-5 is a side elevation of the carrier showing the tension and take-up arm as raised and acting upon the pawl to raise it from its ratchet and release the supply holder. Fig. 2 shows the take-up arm in its extreme down position and as having moved v the stop motion actuator into operating position. Fig. 3 is a section on line 33 of Fig. 1 looking in the direction of the arrow and showing the stop lever in section having a' portion extemling on either side of the frame whereby it may be caused to stop the machine when traveling either to the right or to the left. Fig. 4.''is a front sectional view of the take-u arm pivot pin showing the arrangement 0 the spring for act ating t same and the mean f r adjusting the tension of the spring. Fig. 5+ shows the slotted head. of the pivot pin.
'F eie. t2? ease new re: taken? arm. v H
Referring to the drawing, 10 designates the carrier frame which is provided with a standard 11 and a central fixed spindle 12 on which latter may be mounted the spool or holder for the supply of yarn. The supply may be of either the cop or bobbin type and the spool on which it is wound may have a ratchetv head either at its upper or lower end, if desired. I have herein illustrated the common form of cop mounted on a spur with its ratchet head 13 at its lower end, the same being provided with a pluralitv of, teeth 14. I have also provided a pawl member 15 adaptedto engage these ratchet teeth 14, said pawl being provided with a body portion 16 adapted to slide vertically on the standard 11, and also on a pin 17 which passes through the body of the pawl and is "supported at its upper end in the lug 18 and at its lower end in the lug 19 in the 'frame. I have also provided a small coil spring 20, one end engaging the underside of the lug 18 and the other resting upon the pawl whereby the latter is moved quickly back into engagement with the ratchet teeth after having been raised to permit the holder to rotate for the purpose of releasing the yarn. In order to operate this pawl by the action of the yarn I have provided an arm 21 which is fixed to the pivot pin 22 by engaging a flattened portion 23 at its end, to which it is bound by the nut 24. This pivot pin is loosely mounted on the bushing 25 fixed in the frame 10, the head 29 of the pin being slotted as at 26, see Figs. 4 and 5. A small disk 27 is mounted on this pivot and has a pin 28 adapted to engage the slots 26 in said pivot head 29 and a coil spring 30 is wound about the pivot with one end engaging the disk 27 and its opposite end engaging the bushing 25 whereby a yielding tension is exerted on the arm which tension may be adjusted by pressing the disk 27 inward, rotating it against the coil and inserting the pin in another of the apertures 26. The end of this tension arm opposite its pivoting point is provided with a hook-shaped portion 31, and the yarn a is led down from the hole 32 in the standard on its way to the guide eye 33. This arm is provided with a laterally extendingfinger 34 which is adapted to engage the underside of the pawl body 16 to raise the pawl 15 out of engagement with:
- work. To accomplish this purpose in a simby an excessive pull on the yarn during the when an excessive amount of yarn has been released from the holder, andwhich is in danger of becoming entangled or knotted and liable to produce bad effects in the ple and efi'ective way I have provided a pair of lever members36 and 37 located on opposite sides of the frame 10, see Fig. 3, both being pivoted by the single pin 38. Across the front of these levers 1s riveted a plate 39 which extends laterally a. suflicient distance both to the right and to the left, so that this stop lever may be caused to engage the stop motion on the machine either when the carrier is traveling to the right or to the left. Where this provision is not made special carriers have to be constructed,
' some for a left hand travel and some for a right hand travel, but with my improved construction any of the carriers may be used for either the right or the left hand travel. In order to control the operation of this stop lever I have provided an upwardly extending portion 40 on one of the levers, the forward edge 41 of which is preferably made in a cam shape adapted to be engaged by the finger 35 of the tension yarn 31 by which it is normally held out of operating position. At the base of this camcurve is a shoulder 42 which is engaged by said finger 35 to force the stop lever into-position to engage the usual stop motion and arrest the action of the machine when the tension arm is moved to its extreme down position under action of its spring 30.
I claim: 1. In a braiding machine, a. carrier comprising a rotatable supply holder provided with ratchet teeth, a slidable member carrying a pawl, means for depressing said memher with its pawl in engagement with said teeth, a yarn tensionand take-up arm, and means mounted on said arm for engaging said member to raise the same and disengage the pawl from said ratchet.
2. In a braiding machine. a carrier comprising a rotatable supply holder provided with ratchet teeth, a slidablv mounted member carrying a pawl for releasably engaging said teeth, a spring pressed tension andyarn take-up arm. and a lug carried by said arm and adapted upon the raising of the latter a predetermined height to engage said member for raising the same to disengage said pawl from said teeth to emit a ortion of yarn to be withdrawn rom the older.
