- s claims. `(ci. 139-159) 1n a pending application ser. Naas'msz, inea'v May 14, 1939, I have disclosed and claimed a novel picker organization for'use in looms which has proved 4to be a substantial advance in thisy art. The present invention aims further to improve picker structures of the general character shown in said application with a view to providing an exceptionally simple an'd sturdy'construction which will be economical to manufacture and convenient to use, while at the same time having the exceptional length of life and serviceability of the construction shown in my Iprior application.

The nature of the invention will be readily understood from the following description when read in connection with the laccompanying drawing, and the novel features will be particularly pointed out in the appended claims.

In the drawing,V i Figure 1 is a perspective view of a picker stick lug or block made in accordance withthis invention;

Fig. 2 is a similar view of the backer block or elastic pad which forms one element of the picker assembly;

Fig. 3 is a perspective view of the metal holder for the block;

Fig.-4 is a side elevation of the picker assembly; and

Fig. 5 is a .sectional view approximately on the line 5 5, Fig.v 4.l v

in the construction shown,the picker stick lug or block 2 may be of any suitable character, but preferably it is made in accordance with the disclosure in my pending application above referred to. Such a block is composed of a series of plies of woven fabridgsuch for example as Osnaburg, cut on the bias, the 'fabric previously sentially the same characteristics. The heat resisting rubber compounds are very satisfactory. The block or a. built up strip from which it is cut is then molded to the desired form, preferably forming the groovela in its yrearward side to receive the edge being flanked grooves c oi generally `of the picker stick, this groove in orcut out of thematerial at opposite lateral surfaces of the block. 'A hole d also may be formed in the front face to receive the end of the shuttle. 'For 'easons describedmore partic- 1 ularly `by beads b-b. In addition, I

annular form but breaking i into the rearward surface of the block are/molded disposed diagonally with reference to the edges of the front face of the block, the bias cutting producing this relationship.

Iniorderto secure this block tothe picker stick i, a holder 3 of novel form is made of some suit- 5 able spring metal, such as steel or any one of various alloys obtainable for this purpose. A steel holder of in the neighborhood of a sixteenth of an inch has proved very satisfactory. This holder has apertures li-i formed in the ends thereof, and the annular portions of the holder@ surrounding these apertures are madeof such dimensions as to t snuglyinto the grooves c in` the oppositesides of the block 2. The dimensions preferably are made such that the projections e at opposite sides of the'block t snugly into the apertures d -IL and the holder should be made of such dimensions that it is necessary to use considerable force to spring the arms of this member apart in order to snap the ends of the bolder over the projections e`e. Thereafter the block will be held securely in the grip of the holder.

The picker assembly also includes an elastic block or pad 5 preferably comprising a core of 25 rubberized fabric heavily coated with a highly elastic grade of rubber so that the entire' pad will have a verysubstantial degree of. yield or elastic compressibility. As shown, this pad or block is of approximately semi-cylindrical form. In' assembling the parts on a picker. stick, the block 2\ is secured in the holder 3 in the manner above described, the pad 5 is placed in the curve of the holder 3, as shown in Figs. 4 and 5, and this assembly is then forced, on to the upper tapered end of the stick IfPreferably the dimensions` are made such that a very considerablev degree of pressure is required in performingthis pperation so that the assembly will be held securely in place solely by the friction of the block 40 and the pad against the front and rear surfacesr of the `stick.\ It is preferable, also, to have some degree ofclearance betweenthe lateral faces of the stick and the Jadjacent inner surfaces of the holder 3.` 45 With this arrangement the metal holder is not connected directly with the stick at all but is supported on it indirectly solely through the resilient block 2 and the elastic pad 5. Both of these elements have suiiicient resilience or elasticity so that the connection of the block with the stick is a floating connection through'the resilient elements just named. l'

Such a construction has been found by experience to be' effectual in withstanding the disid- ,55

` metallic picker block, a U-shaped sheet metal tegrating action of the pounding and shock to which a picker necessarily is subjected. 'I'he A parts of the assembly can be manufactured eccnomicaily, and can be assembledmn the picker stick with a minimum of labor. In the event that it becomes necessary to replace one of the lugs or blocks, that also can be performed very quickly. In addition to the foregoing, this picker structure has the advantage of affording an exception'ally long period of operation due, I believe, to the manner in which the block is built andv to the fact that the picker assemblyl is supported on the stick by a iioating connection, as 'above described.

While I have herein shown and described a typical embodiment of my invention,-it will be evident that the invention may be embodied in other forms without departing from the spirit or scope thereoi'.

Having thus described my invention, what I desire to claim as new is:

1. A loom picker comprising a resilient nonholder embracing said block and straddling said stick, the -forward -end portions of said holder being interlocked with portions of said block at opposite sides thereof andterminating in the block, an elastic non-metallic pad bearing against the rearward side oi said stick, said pad-fitting into the curved rearward endportio'n of said holder, and said holder maintaining both said tioned, an elastic` non-metallic pad bearing against the rearward side of said stick, said holder maintaining both said pad and the part of said block adjacent to said stick-under compression, and being itself maintained in a iloating condition relatively tosaid stick by the resiliency of said pad and said block. y

3. A loom picker comprising a resilient nonl metallic picker block, a sheet metal holder embracing said block and straddling said stick,`said holder being of U-shaped form and made of spring metal and its forward ends being apertured to receive projections extending from opposite sides of 'said block, an elastic non-metallic pad bearing against the rearward side of said stick, said holder maintaining both said pad and l the part of said block adjacent to said stick under compression, and being itself maintained in a ioating condition relatively to said stick by the resiliency of said pad and said block.
