Specification of Reissued Letters Patent. Reissued Dec, 4, 1917 Original No. 1,193,688, dated August 8, 1916, Serial No. 44,170, filed August 7, 1915. Application for reissue led November 16, 1916.

To all whom t may ooncem:

Be it known that we, MALCOLM CURRY and ALBERT COOK, citizens of the United States, and residents of Holyoke, county of Hampden, State of Massachusetts, and of Fall River, county of Bristol, State of Massachusetts, respectively, have invented certain new and useful Improvements in Band- Tyin Gages, of which the following is a speci cation.

This invention relates to a device adapted for use in tying the spindle driving bands on spinning or twisting frames, or other band driven machinery.

As now commonly tied, the operative depends upon his sense of feel in determining the proper tension to be placed on the bands, and althoughthese operatives become very skillful there is a great variation in the tension of the banding. Tests have shown tension variations of from one-half pound to ten 0r eleven pounds between the various bands on a hand-banded spinning machine. It is obvious that this variation in band tension results in bands which have an insuHicient tension and others which have an excessive tension. Insuiiicient tension results in al failure to maintain the proper speed of rotation of the spindle, or the throwing-oil of the band; and excessive tension results in broken bands, excessive slip due to friction, excessive wear in the spindle bearings and an excessive load on the machine. The variation iii the banding also results in a nonuniform product; and it will be readily appreciated that broken bands due to excessive strain result in wastages of banding, delays in operation and much damage tothe product, due to the flying ends of the broken bands. l

It is the main object of this invention t provide a device which will enable the operative to tie all bands with a uniform tension, the device being' adjustable so that when tied the bands will have the desired tension. It is manifest that in a spinning or twistin frame in which all of the bands have a uniform tension, the product will be uniform; the load on the machine will be reduced to a minimum; and that the spindles will have a uniform speed and a suhstantially uniform wear in their bearings. There will thus result a saving in maintenance of machinery, a saving in handling Serial No. 181,796.

and a maximum amount of production of a uniform product.

A further object of the invention is to provide a4 device which automatically will become locked when the proper tension is secured on the band to thereby relieve the partially tied band'of the regulating tension and permit the operative to use both hands freely in the tying operation, which may then be easily and accurately completed without `danger of lessening or increasing the tension.

.Another object of the invention is to provide means whereby the tied band may be readily released from the tying device and delivered to the whorl of the spindle, the tension regulating device being then released so that it may return to its normal position ready for the next tying operation.

There are other objects and advantages of theV invention, all of which will be more fully hereinafter set forth.

In the drawings, Figure 1 is a side elevation of the device applied and showing a spindle rail and a spindle mounted thereon; /F ig. 2 a plan view; Fig. 3 a plan view showing the plunger and knot-tying member rotated to release the tied band; Fig. 4 a front elevation; Fig. 5 a longitudinal vertical sectional view of the complete device; Fig. 6 a detail longitudinal sectional view with the plunger in its normal position; and Fig. 7 a detail horizontal sectional view with the plunger in its normal inner position.

Referring to the various parts by numerals, 1 designates a socket or cup which is adapted to receive the bolster of the spindle. This cup is provided near its lower end with a clamping screw 2, the inner end of which is adapted to engage the bolster to securely clamp the socket in position on the bolster. Rigidly connected to the socket and extending forwardly therefrom is a supporting arm 3. In the upper end of this arm is rigidly secured a frame 4 which carries a cylinder or barrel 5, the axis of said barrel being perpendicular to the axis of the socket, and substantially horizontal. In the cylinder `is mounted a plunger 6 which fits snugly therein and is yieldingly held by means of a coil spring 7. This spring is attached to the plunger and to an adjusting screw 8 which extends through the outward end of the cylinder. On the projecting end of this screw` isiythrea-ded an:` adjusting nut 9 and a lockvnut 10.y By means of the adjusting nut 9 the' 'screw 8 may be moved and-"thetension ofthe spring on the plunger increased or diminished', with the result .that more; or less pull will be required to' withdraw the plunger from the cylinder. tying'rod 11 is rigidly vconnected to the inner ally .eztendin rod 11 near t e vplunger 6 isa :finger piece Vyori handle.l3 by means of whichfthelunger maybe partially .rotated inl itscylin er.

This operation of transferring the band from the hook to the whorl will necessarily sli htly reduce the tension on the band, but t is reduction in tension may be rovided for by adjusting the spring attache to the plun er, so that when the in the spindle Whorl it will have the desired pull.

As heretofore pointed out, the advantages of banding all of the spindles in a frame at a uniform and minimum tension, are very great and Will readily be appreciated by those familiar with the operation of twisting frames and spinning frames, and it is not necessary to fully enumerate them herein.
