SIDNEY C. BAILEY, OF NEW BEDFORD, MASSACHUSETTS, ASSIGNOR OF ONE- HALF TO THE NORTHROP LOOM COMPANY, OF HOPEDALE, MASSACHU- sn'rrs, ANDsAoo, MAINE.

SHUTTLE-MOTION FOR LOOMS.

PEGIFICATION forming part of Letters Patent No. 510,830, dated December 12, 1893.

Application filed July 31, 1893. Serial No. 481,959. (No model.)

To all whom it may concern.-

Be it known that I, SIDNEY O. BAILEY, of New Bedford, county of Bristol, State of Massachusetts, have invented an Improvement in Shuttle-Motions for Looms, of which the followingdescription, in connection with the ac companying drawings, is a specification, like letters and figures on the drawings representing like parts.

Wooden picker sticks now most commonly in use in connection with rockers adapted to rock on rocker beds are tapered toward their upper ends, and the sticks at or near their lower ends are bolted to usual feet or rockers, and the lug strap or guide through which it is passed is usually confined to the stick by screws. The holes made in the stick tend to weaken it. I

In my studies to improve that class of picking mechanism wherein the picker-stick is carried by a rocker adapted to rock on a rocker bed, I have devised novel means for connecting or clamping the stick to the rocker without the necessity of making a hole in the stick, or of injuring the edges of the stick so that the said stick is left in condition to be. used either end up.

In my invention I may use a stick parallelogrammic in cross section, the cross sections of the stick being uniform. I have also combined with a metallic rocker, as described, a lug strap guide, the said guide being extended up at one sideof the stick, the guide serving as a point of attachment for the lug strap, thus avoiding the strain of the lug strap upon the picker-stick.

Figure 1 shows part of the front of a loom with part of a picker-stick supported in ac cordance with my invention; Fig.2 a view looking at the parts represented in Fig.1 from the right. Fig. 3 is a section in the line m Fig. 2. Fig. 4 is a section in the line on Fig. 1; Fig. 5 a section in the line 00 Figs. 1 and 3; Fig. 6 a section in the line a Figs. 1 and 3. Fig.7 shows different views of the rocker; Fig. 8 difierent views of part of the clamp. Fig. 9 shows views of the second half of the clamp. Fig. 10 shows the arm to which the lug strap is attached. Figs. 11, 12 and rocker bed or support B for the shoe or rocker 0 being attached to the lay journal by a screw 0'.

The rocker shown consists of a curved shoe 0 having an upright hollow portion 0' open at one side to leave flanges to receive between them and serve as a guide for the half 01 of the stick clamp d, 01', each half being shown in several views in. Figs. 8 and 9. The interior of the upright c of the rocker has a recess 16, see Fig. 7, said recessed portion having a hole 15, the recess being adapted to receive the end of the loop-like part4 of the portion dot the stick clamp, to be described, and this portion a has also shoulders, as at 22, see Fig. 7, to support the outer side of the part d of the stick clamp. The half or portion dof the stick clamp shown in Figs. 1, 3 and 8 is represented as a metallic bar made claw-shaped at one side or provided with lips to' embrace one edge of the picker stick e, said lips being herein shown as notched or cut away at two points, as 2, 3, the notches 2 receiving the sides of the looped p t 4. of the half or portion d'of the clamp to be described. The half 02' of the clamp shown in Fig. 9 is composed of an upright portion having extended from it at right angles a box-like loop 4 provided with a threaded portion 5, said upright portion having'at one side a slot 6, the metal at the interior of the said upright portion and bordering said slot being shown as countersunk to receive the other than round head 7 of a bolt 8, see Fig. 14, to thus prevent said bolt from rotation in the slot as the nut 10 cooperating with said bolt, see Fig. 5, is being turned on or 0F.

The bar (1 as shown in Figs. 1 to 8, has a retaining leg 12 which is passed through aslot in the rocker bed B to thus help keep the rocker in place.

To assemble the parts, the bolt 8 will be put in place in the half (1, the slotted part 13 of the lug strap supporting arm f having at its upper end preferably a slot 14:, see Fig. 10, will be put onto the bolt, and the nut will be applied and turned until the lug strap arm is firmly secured in the proper or desired position vertically. The half (Z of the stick clamp will then be put into the box-like loop 4; of the part (1' until the open part 2 comes opposite said loop, and the end of the screw 5 will then beput through the hole in the upright portion 0 of the rocker, the end of the loop entering the recess 16 of the rocker, see Fig. '7, and the nut 18 will then be caught upon the threaded part 5. The end of the stick may now be put between the clamps and pushed down against the heel of the rocker as in Fig. 3, and the nut 18 may then be screwed home to firmly draw the part d of the clamp toward and into the upright part c of the rocker, the part (l of the clamp resting with its back against shoulders 22 of the said upright portion, see Figs. 7 and 3. The rocker with the stick clamped in place will rest on the bed B, and the lug strap 9 connected with some suitable actuating arm g suitably moved to throw the shuttle, may be led through the slot 1-1 and about the stick. The lug strap is not connected with the stick, but to the supporting arm f, yet the strap may embrace and aid in steadying the stick between its ends.

The modification Figs. 11 to 13 is to illustrate another form of bed and rocker, the bed h, see Fig. 11, having a horn h to enter a holein the rocker 72?, the horn serving the purpose and being equivalent to the part 12 in Fig. 3, the stick 8 and its clamping members being otherwise the same as in Figs. 3, 8 and 9.

By the term straight picker stick I mean a stick of uniform width and thickness, as contradistinguished from a tapered stick.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. The combination with a rocker, composed of a shoe having an upright arm 0', of a stickclamp composed of a socketed portion to receive and completely surround the stick, and a detachable independent bar entering said socketed portion and bearing against a portion of the stick, and means to connect the said socketed portion with the said rocker, substantially as and for the purpose set forth.

2. A rocker composed of a shoe 0, and an upright arm 0' provided with flanges and having a hole 15 and a recess 16; combined with a stick-holding clamp composed of a socketed portion cl having a loop-like extension 4 and a threaded portion 5 to enter the hole 15 referred to; a nut 18 for said threaded portion 5, and an independent bar cl entering said loop-like extension and cooperating with one edge of the stick, substantially as described.

The rocker consisting of a shoe 0 and an upright arm 0' provided with flanges and having a hole 15 and a recess 16; and a stick-holding clamp composed of a socketed portion cl having a loop-like extension 4: and a threaded portion 5 to enter the hole 15 referred to, a nut 18 for said threaded portion 5, combined with an independent bar d notched as at 2, and entering said loop, the latter engaging said notches, substantially as described.

4. The rocker consisting of a shoe 0, and an upright arm 0 provided with flanges and having a hole 15 and a recess 16; and a stick-holding clamp composed of a socketed portion (1 having a loop-like extension 4 and a threaded portion 5 to enter said hole 15; a nut for said threaded portion 5, and a rocker-bed; combined with an independent bar 61 having an extension 12 carried below said rocker, the shoe rocking upon said rocker-bed, substantially as described.

5. A rocker composed of a shoe 0 having an upright arm a; a rocker-bed to sustain the said shoe; a picker-stick clamp composed of a socketed portion having a loop-like extension to embrace and completely surround the picker-stick; means to connect the said socketed portion to the upright portion 0' of said rocker, and an independent bar cl entering the loop-like extension of said socketed portion between it and said stick, combined with a lug strap guide connected to the said socketed portion, to operate, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

SIDNEY C. BAILEY.
