PICKER FOR LOOMS.

Application filed March 25, 1927. Serial No. 178,401.

This invention relates to new and useful improvements in loom pickers, and the object of the invention is to provide a strong, simple, and inexpensive striking attachment or picker, which will be easily assembled and repaired and which will have the proper amount of elasticity to secure the best results while operating in the loom.

Another object is to provide a picker for looms, the cushioning block of which will be quickly and easily renewed.

In my invention I provide a loom picker consisting of a plurality of cushioning discs enclosed within an open-ended cylinder, which has an inwardly turned flange to hold the discs in position. A removable cap is detachably secured to the cylinder and said cap is provided with means for attaching the picker to the picker stick. Means are also provided to steady the picker and prevent turning of same on the stick. The cushioning blocks or discs are easily placed within the cylinder and are held in place by the cap and the flange.

In the drawings which illustrate my in vention:

Figure 1 is a side elevation of the picker and its relation to the shuttle during one part of the operation of the loom.

Figure 2 is an end elevation of the device shown in Figure 1.

Figure 3 is an end elevation ferred form of picker.

Figure 4 is a sectional side elevation taken on the line 14 Figure 3.

Figure 5 is an end elevation of the picker cylinder showing the means of holding the cushion blocks therein.

Figure 6 is a side elevation of a modified type of picker.

Figure 7 is a sectional side elevation taken on the line 77 Figure 6.

Referring more particularly to the drawof my preings, 11 designates a plurality of cushioning discs which may be made of leather or such like resilient material, which are placed within a cylindrical shell 12, having an inwardly turned flange 13 at one end 14, to hold the discs in position. The end 15 of the cylinder is provided with an internally threaded portion 16 adapted to engage with the externally threaded cap 17. A clamp 18 projects upwardly from the cap and is adapted to embrace three sides of the picker stick 19 which is preferably of rectangular form as shown in Figure 2. In the preferred iorm shown in Figures 3, 4 and 5, the free ends 20 of the clamp'pass through apertures 21 formed in the cap and are bent outwardly or inwardly against the inner surface of the cap to hold the clamp in position. In the modified type shown in Figures 6 and 7 the clamp 18 is made integral with the cap 17*. All other parts of the picker are made somewhat similar to those shown in Figures 3, 4 and 5. To se cure the picker to the picker stick, a screw bolt 22 may be employed, said bolt passing through an aperture formed in the stick to engage with a threaded aperture 23 in the cap, or the bolt, which is of the countersunk type may be placed through the cap, the stick and the clamp, and provided with a nut, as shown in Figure 6. The locking bolts shown herein are for illustrative purposes only and it will be readily understood that other types of locking devices may be used to hold the picker in position, without departing from the spirit of the invention. A plurality of holes 24 may be formed in the cylinder walls to provide means for tightening the picker or adjusting same in position.

In Figuresl and 2, a shuttle 25 is shown with a point 26 in contact with and acted upon by the picker. The shuttle is moved by the picker and it will be readily seen that by constant use, the force exerted on the picker by the point of the shuttle, or viceversa, tends to spread the cushioning washers. This spreading action is prevented by the interior walls of the cylinder. By making the cushioning block in a plurality of sections, it will be seen that when the disc in proximity to the shuttle has become worn or unfit for use, it may be taken out and replaced by a similar disc. The operation of replacing the disc is very simple as the cylinder is unscrewed from the cap, the discs are then taken out the worn one discarded and a new washer Or disc inserted. The cylinder is then screwed on the cap and the holes in the cylinder are provided to facilitate this operation.

The device is inexpensive to manufacture and may be attached very quickly to the picker stick. The leather washers or discs have the required elasticity for flying the shuttles during the operation of the loom.

Having thus described my invention, what I claim is V 1. In a loom picker, a plurality of resilient discs, a cylindrical casing for the discs, said casing having an inwardly turned flange at one end and an internally threaded portion at the other end, an externally threaded cap adapted to engage with the threaded portion of the cylinder to hold the discs in position, and a clamp extending upwardly from the cap for attaching the picker to a picker stick.

2.'In a loom picker, a plurality of resilient discs, a cylindrical casing therefor, said casing having a flange at one end and an internally threaded portion at the other end,

an externally threaded cap adapted to enthrough the clamp to lock the picker in position.

s 3. A loom picker comprising a cushioning member, a casing surrounding said member and open at both ends, means for securing the member in said casing including a detachable cap closing one end of the casing and means carried by the cap for fastening the casing to a picker stick.

In witness whereof, I have hereunto set my hand.

EDWIN E. RAWSON.
