SPOOL-CARRIER FOR BRAIDING AND WINDING MACHINES.

' SPECIFICATION forming part of Letters Patent No. 632,318, dated September 5, 1899.

Application iiled December 23, 1898. Serial No. 700.103. (No model.)

To all wwm/ it may concern.-

Be it known that I, JOHN MCOAHEY, of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Spool-Oarriers forBraiding and Winding Machines; and I do hereby declare that the followingis a full, clear, and exact description thereof,r'eferen ce being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to the spool-carriers used in braiding and winding machines.

It is fully explained and illustratedin this specification and the accompanying drawings.

Figure l shows a side elevation of the spool- Fig. 2 is a vertical section of the carrier, taken'through its spindle and standard. Fig. 3 represents the sleeve that holds the cop on the spindle separately. Fig. 4 is a View of the under side of the foot of the sleeve. Fig. 5 shows in perspective the pawl and the top clasp connected to it.

The object of this invention is, rst, to enable the-carrier to hold more thread or yarn, then to greatly increase the speed at which they may safely run by reducing their topheaviness, and to greatly lessen the liability of the yarn to be broken and cause stoppages of the machine for the purpose of mending or taking up the slack of the yarn made by the overrunning of the yarn-spool.

By reference to Fig. 2 the construction of lthe carrier will be easily understood.

The foot A of the carrier, the standard C, and the spindle D are usually cast in one piece. The spindle D is then milled down round and smooth to receive a sleeve H, which is made to turn easily on the spindle and is held by a washer and a screw ZJ at the upper end of the spindle. receive the cop of yarn N, (see Fig.` 1,) which is wound solid on a paper tube and is slipped on and OEE of the sleeve H without disturbing any part of the carrier. The sleeve I-I is shown separately in Figs. 3 and 4, which are respectively a side elevation and a view of the under side of the hollow ilanged foot B ot the sleeve.

The foot B has a number of The sleeve H is made to studs d u. projecting out horizontally on all sides. A sliding pawl g (seen in Fig. 5) consists ot a plate divided vertically into legs by a notch extending up from thelower end, and

each leg is provided with a foot e, extending out horizontally toward the spindle D. A stud c is put on the face of the pawl at the top, and the pawl stands astraddle of the iiange o, that connects the standard and the 6o spindle andis so placed that when the pawl is down the stud c will be between two of the studs a on the foot of sleeve I-I and prevent it from turning. A loose sliding clasp J is placed on the upper part of the standard O and is connected to the pawl g by a wire h, which is made fast to both the clasp and pawl.

The operation ot' these parts is this: WWhen the carrier is running in the machine and 7o there is the proper amount of slack yarn to allow them to pass in and out of the braid, the weight 'W will hang in the bight m ofthe yarn, between the hole S in lthe standard and the guide-hole t at the top, and the yarn will have the proper tension on it and the weight will take up or let out the charge in length as the carriers pass in and out in braiding. In this position the stud c of the pawl g will stand between two of the studs ct on the foot 8o of the sleeve and hold it from turning, but when more yarn is required the weight W will be raised by the yarn and strike against the clasp J. (See dotted lines in Fig. 2.) This will raise the clasp and the pawl g, attached to it, and raise the stud c above the studs a, allowing the sleeve and cop N to turn and let off more yarn, and at the same time the feet e e will be thrown up against the under side of the foot of the sleeve and act as a 9o will take up, for in that case there would be no tension onthe yarn and the braid would be spoiled. This entirely prevents the over running of the yarn, which has always been a great trouble and has made it necessary to run the machine at a slow speed, curtailing` roo the product accordingly. But this improvement alone would not suffice to allow the speed to be greatly increased. Itis also necessary to make the carrier less top-heavy, so that the centrifugal force, as they pass in and out quickly, will not swing out the heavy top and cramp the guiding-flange d in the raceway. This liability has had a great deal to do in keeping the speed down. The t0p heaviness has been greatly reduced by putting the let-oit motion down as near the plate the traveler runs on as possible.

To sum up in a few words the advantages gained in this carrier: It largelyincreases the amount ot' yarn that can be carried, so it will run much longer and have less stops for reiilling. It will run at a greatly-increased speed because it is less topheavy, and it will not let oiii more yarn than is wanted when run fast, and it also lessens the amount of power required to run it and reduces the wear by preventing the cram ping of the iiange in the raceways. There are no loose parts liable to be thrown off by the increase of speed and cause damage by falling among the running mechanism, and the operation of replacing an exhausted cop with a full one is greatly facilitated, as it is not necessary to displace any part of the carrier, as it is with the carriers now in use. By this saving of time and the larger amount of yarn carried the operative is enabled to tend many more machines and at a higher rate of speed than is possible with the carriers now in use.

Having thus described my improvements, I claim as my inventionl. In a spool-carrier the combination with a foot having a standard and a spindle, of a sleeve fitted to turn easily on said spindle, to

hold a cop of yarn, a fastener on the upper end ot the spindle to keep the sleeve from rising, a pawl, a brake attached to said pawl, a clasp, to slide on said standard, a wire to connect said pawl and clasp, a iiange between the standard and spindle, to controlthe motion of said pawl laterally, a weight hanging free of the pawl, substantially as described. 2. ln a spoolcarrier of the kind described, the combination with a spindle, of a sleeve litted to turn easily on the spindle, a foot to said sleeve having studs extending out from it, a drop-pawl having a stud arranged toengage with said studs, and having its lower end extended horizontally under the foot of said sleeve, a weight, with means for operating said pawl by the weight, substantially as described.

3. ln a spool-carrier of the kind described, the combination with a carrier-standard and a spindle, of a spindlesleeve fitted to turn easily on the spindle, a foot to said sleeve having studs extending out from it, a droppawl having a stud arranged to engage with said studs, and having its lower end extended horizontally under the foot of said sleeve, a carrier, a clasp fitted to slide on the carrierstandard, a wire connecting said pawl and clasp, substantially as described.

In testimony whereof I have hereunto set my hand this 17th day of December, A. l). 1898.
