BUILDER-MOTION.

To all whom it may concern: o Be it known that I, EMMERICH H. KRIS- TEK, a citizen of the United States, resid- 1 ing at North Grosvenor Dale, county of Windham, and State of Connecticut, have invented an Improvement in Builder-Motions, of which the following description,

in connection with the accompanying drawings, is a Specification, like letters on the drawlngs representing like parts.

The invention to be hereinafter described relates to spinning machines for spinning and winding yarn onto carriers or bobbins, and moreparticularly to the builder motion in such machines whereby the desired character of wound bobbins or carriers is produced. I I

In some types of filling replenishing looms, it is desirable that the wound bobbins or carriers used for laying the filling shall be provided with preliminary or initial windings to cooperate With certain mechanism of the loom to cause filling replenishinent only when the filling on the bobbin or carrier in use has become practically exhausted. When the carrier or bobbin to be abandoned is ejected from the shuttle, it

still contains some windings offilling which constitute waste and must be removed from the carrier or bobbin before it can be again supplied with a load of filling. It is of importance, therefore, that the preliminary or initial windings, which are frequently called a bunch, shallbe so placed,- upon the bobbin or carrier "that theamount of waste shall be reduced to a minimum and yet the bobbin or carrier be supplied with the maximum load.

Many attempts have been made to carry into efi'ect these desirable characteristics, among the most simple and successful of which is that of Charles E. Lovejoy, as described and claimed in his application, Serial No. 780,863, filed July 24, 1913, wherein a deflector was attached'to the flexible connection between thebuilder motion and ring-rail and caused to act in a manner to secure a proper formof initial windings or bunch. The simplicity of this device, its adaptability for ready application, and its effectiveness in operation, have dictated its incorporation in the well-known Howard & Bullock type of spinning machine; but owing to thecharacter of this type of spinning I Specification of Letters latent.

purposes of the present invention will. best 5 be made clear from the following descriptlon (and accompanying drawing "of one practicalform or'embodiment of the inven- Patented May 18,1915. Application filed November 21,1914 Seria1 1\T o.873,277.

tion, it being understood that it'is not res strlcted to the particulars and details shown,

but that it may be varied within the true" as set forthbythe scope of the invention, clalms.

Inthe drawings :Figure 1 is a perspective view of sufiicient frame, 'nections' to make clear the present invention; 2 is a diagrammatic viewjshowing'the connections between the builder-moi portions of a'spinning f- J bullder motion, and ring-rail contionand ring=rail; Fig. 3is a side elevation of a wound bobbin or .carrier having a bunch,as shown by dotted lines.

Pivotally mounted at 1"upon a"suitable support or themachine'frame, is the builder motion frame comprising the upright larm 2 and side arm 3, the latter of which; has so 7 the extension 4 jointed thereto at 5, and pro vided with a Vroll'6 to bearupon ajc'am by a which the builder motion frame may be rocked about the, pivotal mounting 1. An adjusting screw 8 serves to define the relation of the arms 3 and 4' andfto transmit through the downward motion of the arm 4 the arm 3 :to the builder fra'me.

Mounted. on a shaft 9 extending transverselyof the builder frame, is the ratchet or pick wheel 10 which receives'ste'p-by-step rotative movement in usual manneryas the builder frame is rocked. On the inner end of the. shaft 9 is a beveled gear ll which is operatively engaged with a bevel gear 12 s'ecuredto theilower portionof the screw shaft 13-having bearings in a block 14 at, the top portion of thebuilder motion frame, and a block 15at the lower'portion thereof; the.

construction being such that as-the pick" wheel or ratchet 10 is turned step-by-step, the screw 13 will be gradually rotated.

A movable block 16 is threaded upon the screw 13 and its rearportionbears against the arm 2 of the builder motion frame,the construction being such that as the screw is rotated, the block 16 will be moved .along the, same. The" block 16 is preferably limited in its movement in a downwardrdirection by the projection 18 and the top of the block 15, and its raised position is defined by the screws 19.

Projecting at the sides of the block 16 are the side pieces 20 which extend beyond the sides of the upright 2 of the builder motion frame, and to each of these is secured one .end of a strap or flexible connection- 21 which passes down from said blockand about rolls or guides 22 secured to the builder frame at the lower portion thereof. The other ends of said straps or flexible connections extend upward from said rolls or guides and are secured to a roll 23 mounted in suitable brackets 2st projecting from the upright arm 2 of the builder frame, the construction being such that ii": the block 16 starts downward froinits upper position, the downwardly-extending flexible connections 21 will permit the roll 23 to turn contra-clockwise, viewing Fig. 2, and conversely, when the block 16 is moved upward the roll 23 will be turned in the opposite direction, as will be readily understood The ring-rail 25 is provided with downwardly-extending rods 26, as usual, provided with toes, such as 27 which rest upon the pins 28 extending from an arm 29, said arm being secured to a rocking sleeve 30 on a shai't 31, Fig. 1. The sleeve 30 has an arm 32 carrying a weight 33, and an arm 3 1 which is connected to the roll 23 by a flexible connection, the construction being such that the ring-rail is raised by the weight 33 and is lowered by the builder motion through the flexible connection.

The flexible connection between the roll 23 and rocking arm 34: may be variously formed, but as herein shown, it comprises a part 35 having one end secured to the roll 23 and its other end secured to a roll-'36 having a cut-away portion 37 to whichis secured one end of a chain or strap 38, Figs. 1 and 2, the other end being carried under a roll 39 from which leads the part 40 secured to the rocker arm 34. 4 From the construction described, it will be noted that the weight 33 will lift the ring-rail in propertionas it is permitted tofdo so by the connection between the builder motion and rocker arm 34, and in order to modify this lifting action that a proper form of preliminary or initial winding or bunch be produced and a quick get-away be secured as such bunch is completed, that part of the flexible connection between the rolls 33 and 36 has secured thereto the deflector or finger 41. v I

The deflector or finger 41 may be of appropriate form and character as fully described in the application of Charles E. Lovejoy, before-mentioned; but in the present invention, it is associated with the Howard & Bullock builder motion modified and reorganized as hereinbefore described, so

that on starting the preliminary or initial windings, the block 16 being at the top portion of the screw 13, the fleXible connection 21 passing downward about the rolls 22 and then to the roll 23, will cause said roll to be turned clockwise, Fig. 2, to the limit of seen movement, so that the deflector or finger 1 will deflect or bend the connection 35 its maximum amount, and as the winding proceeds, the block 16 will descend, thus giving up the flexible connection 21, which, passing around the roll23 to the right, Fig. 2, permits the weight 33 to turn said roll 23 contra-clockwise progressively and cause the deflector or finger to deflect the connection 35 less and less, as the ring-rail is raised in successive windings, until at the completion of the bunch or initial windings, the deflector or finger will be clear of the roll 23, which may for identification be known as the finger deflecting roll, andcease to deflect the connection 35, whereupon the regular traverse due to the builder motion, is re sumedr V e The cut away roll 36 in connection with the deflector or finger 41 operating as described, enables a more rounded and desired character of bunch to be formed, substantially as pointed out in the application of Lovejoy, before-mentioned, suchpa'rts being adaptable to the Howard& Bullock type of machine by the reorganization and reconstruction as hereinbefore described The character of the filled bobbin and bunch produced, is Well shown in Fig. 3, whereinthe regular windings 4L2 cover the bunch 43,;dotted lines, and the base portion of the filled bobbin is formed full and rounded.
