BUILDER MECHANISM.

Application filed April 17, 1924. Serial No. 707,129.

To all whom it may concern.-

Be it known that I, ROBERT IV. GOSSETT, a citizen of the United States of America, and a resident of Spartanburg, county of Spartanburg, and'State of South Carolina, have invented certain new and useful Improvements in Builder Mechanisms, of wh1ch the following is a full and clear specificatlon.

This invention relates to that well-known type of builder mechanism employed in spinning-frames in which the ring-rail is given a transverse movement, with a gain at the end of the up movement and an equivalent loss at the end of the down movement, means being provided whereby the ring-rail is given a specially-controlled traverse at the beginning of the winding to thereby preliminarily wind on the spindle a bunch. The special object of the present invention is to provide a simple bunchforming mechanism that maybe used in connection with any of the well-known builder mechanisms now in general use.

In the drawing I V Fig. 1 is a side elevation of so much of a builder mechanism for spinningframes as is necessary to show my invention;

Fig. 2 is a vertical sectional view line 22 of Fig. 1; i i

Fig. 3 is a vertical sectional view on the line 33 of Fig. 2; Q

Fig. 1 is a horizoutal'section on the line 4l--il of Fig. 3;

Figs. 5 and 6 are proved half-pulley In the drawing annexed, 1O designates the usual pivoted builder-bar which is adapted to be depressed at intervals by the usual cam (not shown) and which carries the usual pick or gain-wheel 11 affixed to a shaft 12 carrying the usual worm13, this worm having constant mesh with aworm ear 1 1 affixed to a chain-pulley 15. The

iihain or chains 16 from this pulley exdotail views of my imtend upwardlyover a pulley 17 and thenceto the quadrant of the usual weighted lifting-lever 18. The foregoing mechanism operates in a manner well known.

On the shaft 19, on which is journaled the combined gear and pulley 14l15, is journaled another pulley 20 larger in diameter than the adjacent pulley 15. This pulley 20 is adapted to be clutched to the pulley on the 15 by means of a clutch consisting of a. pin

22. In the pulley 20 is mounted a thrust-pin 23, this thrust-pin being normally projected by a spring 24 in a direction away from the clutch-pin 21 and being so positioned in the pulley 20 that it will aline with said clutchpin 21 when the pulleys 15 and 20 are relatively rotated.

To push in the pin 23 and thereby unclutch the wheel 20 from the pulley 15, I provide a lever 25 pivoted at 25 and having an upstanding arm 27 having a rounded inner face adapted to be forced against the projecting end of pin 23; the lower end of the lever 25 is turned to a horizontal position and extends to a point near the wormshaft 12 and in the path of a cam 26 affixed I to said worm-shaft. This cam 26 is carried by a collar 27 affixed to the shaft by a setscrew 28, thereby permitting the cam to be rotatively adjusted on the worm-shaft. It will be observed that the rotation of the cam 26 will swing the lever 25 on its pivot 25 and thus cause the upstanding arm 27 to push the push-pin 23 inwardly far enough to release the wheel 20 from the clutch-pin 21. It is desirable to provide the lever 25 with a weight 29 to keep its horizontal end in contact, or approximately in contact, with the cam 26, and, in order to permit the cam 26 to pass the lever 25, the nose portion 30 of the lever is hinged to the lever at 31 and held in its normal position by a spring 32.

A chain 33- extends from the large pulley 20 to a pulley 33, on the same shaft with the aforesaid pulley 17; and another chain 34; extends from a half-pulley 35 of the usual form to the quadrant of the liftinglever 18. At the beginning of the operation of the machine, the clutch-pin 21 is in locking engagement with the bunch-chain wheel 20 and the push pin is opposite the upper end of the cam-arm 27. The work of building the hunch is done entirely by the chains 33 34: and the parts cooperating therewith, the main or service-building chain being slightly slack. As is well understood, the first few reciprocations of the builder-bar 10 give to the ring-rail the traversing action necessary to build the bunch, and thereafter thereby regularly build up the windings on the bobbin in the usual manner.

To vary the traverse during the making of the bunch, I make the half-pulley 35 1o tatively adjustable with respect to the pulley 33. These two pulleys are rigidly attached together by means of clamp-screws tapped into the body of pulley 33 and ex tending through arcuate slots 37 formed in the body of the half-pulley. The body of the halt-pulley is set in the adjacent face of the pulley33, as shown in Figs. 5 and 6. iVith this construction, it will be observed that the half-pulley may be rotatively adjusted in either direction to thus vary the'length of the traverse of the bunches of different lengths.

The length of yarnus'ed in making the bunch is determined by the position of the cam 26. lVhen this camQG forces the lower end of lever outwardly, the cam-end 27 of this lever unclutches the pulleys 20 and 15, to thereby 'slacken the l)iii1clibi1ilcli1ig chain 33 and thus stop the bunch building. The rotation of the worm-gearand the pulleys l5 and 20 is so slight during the bunch building operation that the push pin 23 does not'pass fronrunder the cam-finger 27. By rotating'the adjusting cam 20011 the wormshaft, the unclutching action may be brought about sooner or later to thusvary the length of theyarn that is put into the bunch. The length of the bunch on the ring-rail. to thereby provide for building spindle is varied by i'otatively adjustingthe halite-pulley, as'liei'eiiibefore described.

lVhen the bunch-building pulley 20 is re leased, the workof building then falls en tirely on the chain 16. The action then continues as usual untilthe bobbins are entirely built up, the bunch-chains 3334 beingidle during this work of. laying the service layers on the bobbin, altho, of course, the chains filth-3% continue to pay oil their pulley. .iy the time'the bobbin is the freely running pulley 20 has been car ried around by its chain far enough to bring a radial shoulder 38 on a cam 39 carried by the pulley 20 to a point behind a stop d0 pivotally mounted on an adjacent part of the frame and adapted to normally rest on the circumferential edge of 02111189, said stop dropping down behind the shoulder 38 to therebv prevent the pulley 2O rotating Then when the? in the opposite direction. operative in the usual manner, through the worm 13, rewinds the main builder chain 16 upon its'pulley 15, the pulley 20 will rotate backwardly with it, by reason mainly of the friction generated by the clutch-pin 21 bearing on the adjacent face of the pulley 20, until the shoulder 38 strikes the stop 40. At

this point, two things happen practically simultaneously:

the clutch-pin 21 has been brought around to a point coincident with 811 511111111211 1'8CGSS 111 haltpulley in each of its completed,

the thrust-pin, thus permitting the clutch pinto goint'o locking action with wheel and, secondly, a cam 41 carriedbymain chain-wheel 15 comes under the stop 4-0 and lifts the same high enough to permit the shoulder 38 to pass under the stop. The two pulleys are then looked together during the remainder of the rewinding operation, when the mechanism is ready for another building operation.
