To all whom itma concern:

"Be it known. t at I, WILLIAM H. Gom- SMITH, Jr., of Biddeford, in the count of f the York and State of Maine, a citizen 0 United States, have invented a new and useful Improvement in Builder-Motions, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explainin its nature.

My. invention relates to a bullder motion adapted to make either a filling wind or a warp wind.

The essential object of my invention is to provide a builder motion capable of considerable variation in the production of a filling wind for varying the character of such wind, and which builder can easily be converted into one for making a warp wind.

The invention can best be seen by reference to the drawings in which an embodiment thereof is shown and such portion of a spinning frame as is incidentally used for supporting various parts of the builder.

Figure 1 shows the builder in side elevation. Fig. 2 is a section on the line 2-2 of Fig. 1. Fig. 3 is a section on the line 33 of Fig. 1. Fig. 4 is a forward end elevation of the builder, other parts to which reference will hereinafter be made being shown in side elevation. Fig. 5 is a front elevation of a detail of construction to which special reference will hereinafter be made. Figs. 6, 7, 8 and 9 are diagrammatic side elevations of the builder showing certain varia tions obtained in the operation thereof for varying the character of the wind as will later be more fully explained. Figs. 10 and 11 are side elevations of the builder when altered to make a warp wind.

Referring to the drawings :1 represents the builder arm; 2 the stud on which the' arm is pivotally mounted and which has any suitable fixture or base of support as a frame 3 which corresponds with the end of a spinning frame. The builder arm is overweighted by a weight 4' on the end thereof.

Arranged upon the rear side of the I builder arm is a cam roll 5 (see Fig. 2) engaging which is a cam 6' for melting the arm. This .cam is supported and operated in any suitable manner. In the drawing the cam 15 shown ivetally mounted upon a stud 7 to t frame :3. Above the builder arm 1s arranged a pulley 8 pivotally mounted to turn within a carrier 9,. This carrier ism-ranged to turn within a suitable bracket 7 10 upon an axis 11 at substantially right angles to the longitudinal line of the builder arm. In other words, the pulley 8 not only turns this carrier, but is also arhas a curvature normally concentric with the 11 abovereferred to and is mounted within a frame 16 carried by the builder arm, the arrangement of the parts being such that the rack may have either a forward or reverse endwise movement around the axis 11. The rack is held against lateral and edgewise displacement by the inner side or face of the frame against which it bears, while the top and bottom edges of the rack are confined by flanges 17 and 18, respectively, which form guides for the rack.

Pivotally secured to the rack at a point adjacent the inner end thereof, or that near- 0st the fulcrum of the builder arm, is a pulley or sheave 19 around which the chain 12 is passed from the pulley 8. Secured also to the rack just forward of the sheave 19' is a segment 20. The curvature of this segment is such that the bottom edge 21 thereof may normally present an arc concentric with the path of the rack and practically flush with the bottom peripheral edge of the sheave 19 so that the chain 12 after passing over the sheave 19 may thence extend outwardly beneath the edge 21 of the segment to bear against this edge. The segment 20 is secured to the rack by screws 22, theheads of the screws being preferably countersunk. The inner end of segment is adjutabl ing fixedly secured to the rack and also as presenting a bottom edge concentric with the path of the rack, provision is made whereby the bottom edge of the segment against which the chain bears may occupy a position eccentric with relation to the path of the rack. For obtaining this effect the secured to the rack, rovision being ma e for such adjustment y slots 24 formed in the segmentthrough which the screws 22 extend. These slots 24 are concentricwith the sheave 19 in orderv that the bottom edge 21 of the segment may always be flush with the bottom peripheral edge of the sheave, whatever the adjusted position of the segment may be. Provision is also made whereby the end of the chain which connects with the holder may also have a variable point of fixture with relation to the axis of the sheave 19 around which the chain is passed. This effect is obtained by the formation of a relatively long vertical slot 25 in the holder, the retention of the chain being efl'ected at any point in the holder within the extenslon of this slot.

The rack 15 is moved by means of a worm 27 on a shaft 28 journaled to turn within the builder arm. For operating this shaft there is arranged upon the outer end thereof a ratchet wheel 29. This wheel has a hub 30 through which passes a set screw 31 for fixing the wheel to the shaft. Inconjunction with this wheel is an overweighted pawl 32 pivotally secured to the builder arm. Cooperating with the pawl 32 is a finger 33 adjustably mounted on a bracket 34 having any suitable fixture of support, as for example, the under side of the side bar 35 of the spinning frame, a portion of which is shown. The coordination and consequent operation of these parts last described for effecting the rotation of the shaft 28 and movement of the rack 27 need no special description as they are well known to those skilled in the art.

The mechanism above described is that especially adapted for making a filling wind or that in which the ring rail has a normal relatively slight traverse or reciprocatory movement with relation to the bobbin and also a gradual increase in elevation with relation thereto, which will hereinafter be referred to as gain. The extent of traverse depends upon the extent of rocking motion imparted to the arm of the builder and,- also, upon the point where thechain leaves the builder arm with relation to its point of fulcrumage. In other words, the traver'se depends upon the position occupied by the sheave 19, the traverse sheave is movedoutwardly along the longitudinal line of the builder arm away from its point of fulcrumage, or diminished as the sheave is moved in a reverse direc- The gain depends upon the letting out of the chain 12, the extent of gain during any interval depending upon the amount the chain is let out during such interval. For making a filling wind the-usual practice is to start with a short traverse and gradually increase the length of the traverse to the end of the wind. The gain, however, is largely a matter of choice, a constant or normal gain being preferred in some instances; a variable gain in others. Referring now to this device in the light of these considerations, the operation is as follows: The rack 15 is first moved inwardly in the direction of the fulcrum of the builder arm to a position where the sheave 19 will occupy such near relative position to the fulcrum of the builder arm as'to obtain the desired initial shorttraverse. Assuming now the motion to be set in operation, the rocking movement of the builder arm tends to bring the pawl 32 in contact with the finger 33 which. tends to actuate the ratchet wheel 29 turning'the shaft 28 and worm 27 thereon and moving the rack 15 outwardly upon the builder arm, thereby causing a continuing outward displacement of the sheave 19 carried by the rack and accordingly increasing the extent of traverse. The movement of the rack and sheave l9 and consequent increase of traverse is very slight for each reciprocation of the builder arm and depends upon the extent of movement imparted to the ratchet wheel, this depending upon the graduated or adjusted position of the finger 33 which is engaged by the pawl for actuating the ratchet Wheel. The increase in traverse is substantially a normal increase although owing to the curvature of the rack the sheave 19 will tend to move faster. along the longitudinal line of the rack as the movement of the sheave approaches a line parallel therewith, the tend ency of the construction accordingly being that the sheave 19 will-be moved slightly faster during a prescribed interval as approach is made to the end of the wind, the sheave then having been moved to a position where its outward movement is in a line substantially parallel with the longitudinal line of the builder arm.

In the present device the letting out of V the chain 12 and resulting gain will de-.

pend upon a variety of considerations including the relative 1 outward movement of the sheave 19 along the line of the builder arm toward the fixture or holder 23 to which ment is eliminated and the chain extends.

in a direct line from the sheave 19 to the holder to which the end of the chain is secured As the sheave moves outwardly upon the builder arm, increasing the traverse as aforesaid, it will follow a path about the axis 11. Therefore the portion of the chain extending between the sheave 19 and pulley 8 will remain constant. 'As the sheave progresses outwardly, howc er, the angle formed between the portion of the chain rendering onto and off the sheave 19 becomes gradually less acute, thereby tending to let out less chain. At the same time the direction or path of the sheave 19 becomes more direct to that point of the holder at which the end of the chain is secured with a tendency to let out a gradually increasing amount of chain, the resultant action being such as to impart a relatively slow gain substantially constant throughout, though tending to increase slightly. This gain in practice has been found very satisfactory and may be considerably varied bythe adjustment of the end of the chain in the holder.

Assuming now that the segment 20 is used and is placed in a normally adjusted position as shown in Fig. 1, or a position where that curved portion of the chain bearing against the',under edge thereof will lie in a position concentric with the path of the rack; in other words, lie in the path described by the sheave 19: Under these cir-' cumstances there is obtained an exact nor-' effected, the gain being a substantially normal gain though slower than when the segment is occupying its normal position asshown in Fig. '1. Assuming that the segment is adjusted to an eccentric position (to the axis 11) as indicated in Fig. 8: Under these circumstances there is obtained a substantiallyconstant though one faster than that obtained when the chain is occupying its normal position as shown in Fig. 1.

Other variations may be obtained dependchain tangentially leaves vthe segment as illustrated in Fig. 9. That is, the device shown is one capable of efl'ecting a considerable variety in gain, and enables one'to obtain that gain which he considers to be most advantageous for his particular purpose.

In Figs. 10 and 11 the aforedescribed builder is shown converted into one for making a warp -wind, slight changes only be mg necessary and these as follows: The cam 6 is replaced by a warp-winding cam 40.

The chain 12 is fastened by a hook 41 directly to a stud 42 on the segment 20 which isvset in a normal position as shown in Fig. 1; In case the segment is not used then' the stud 42 may be secured directly to the side of the rack 15 as shown in Fi .11. The ratchet wheel 29 is reversed ont e shaft 28 or another wheel substituted in which the teeth are reverse to those on ratchet wheel 29 as shown in Fig. 1. The changed position of the ratchet wheel is shown in Fig. 5. In conjunction with the wheel as changed is an overweighted pawl 43 pivotally secured to the builder arm and adapted to engage a finger 44. This finger is secured to a bracket 45 adjustably mounted on the frame 3 whereby the position of the finger 44 may be varied and the pawl 43 strike the same at different adjusted positions of the finger for rotating the ratchet wheel and shaft 28 iii the usual manner as the builder arm is reciprocated. v

The operation is as follows: The rack is first set in a position substantially as shown in Figs. 10 and 11, or in such position as will give the proper initial traverse to the ring rail. As the builder arm is reciprocated the rack will be gradually moved inwardly by the intermittent rotation of the shaft 28 through the operation of the ratchet wheel and connecting mechanism. The

effect is to gradually lessen the extent of traverse as is customary in this kind of wind because the stud 42 with which the chain connects becomes gradually moved nearer to the fulcrum of the builder arm. During this operation there will be no letting out of the chain before characterizedas gain owing to the fact that the stud 42 remains at all times in the direct path of the rack or segment and at the same normal distance from the axis 11.

It is obvious that the mechanism heretofore described may be changed without departing from the spirit of my invention especially with relation to a variance in the mechanism for obtainingt'he filling wind as first described, for varying the character of such wind.
