- make the same of leather i preference to any other material and the leather employed comes in the form of strips and is folded about a form so as to provide a slot through which inserted the tapered end of a picker stick. lVithin the folds of leather, and forming one side of the slot for the picker stick is arranged a so-called picker tail piece. Heretofore the tail -cce has been formed of leather, and because ot the fact that l ather is a porous material, the tail piece, as well as the striking face of the loom picker, was quickly worn away and became considerably out of shape. It has been proposed to substitute for the leather tail piece, a tail piece made of fibrous material impregnated with an adhcsive therino plastic binder which hardens under heat, and this form of tail piece has been quite successful. Because of the difference in material between the tail piece and the loom picker body, and because of the fact that there are no locking means between the two materials, such tail pieces tend to bee come loose in the picker structure.

'vl ith a view to overcoming these difiiculties, l have found it advantageous to provide a tail piece in which corrugations are formed in the manufacture thereof, and such corrugated tail pieces incorporated in the loom picker structure. As the body of the loom picker is of leather, which is of course a fibrous and porous material and relatively soft, such leather during the process of manufacture of the picker, is forced into intimate en agement with the corrugations in the tail piece and tend materially to hold the tail piece in position and prevent its being loosened in the picker structure, The closer afhnity of the leather and the corrugated tail made of material such as is described above will prevent the tail from slipping in the picker structure before it is riveted and is to give a much better wearing surface to me impact of the shuttle when in use.

The object of my invention, therefore, is an improved loom picker.

1928. Serial No. 279,657.

In the accompanying drawings illustrating a preferred embodiment of my invention,

Fig. 1 is a side elevation;

2 is a sectional plan view on the line 2-2 of Fig. l, and

Fig. 3 is a perspective view of a tail piece formed according to my invention.

Referring to the drawings, there is shown a loom picker 1Q comprised of a length of resilient porous material, such as leather, and formed of a plurality of folds to produce a substantially rectangular body, having a tapered passage 11 formed therein and extending therethrough and into which may be inserted the upper tapered end of a picker stick 12. During the formation of the loom picker, a tail piece 13, composed of a fibrous organic material and an adhesive thermo plastic binder which hardens under heat is utilized to fill out the width of the resulting picker, and when in position this member 13 extends downwardly to define the so-called tail piece l l. A plurality of rivets 15 are utilized to hold the material 10 and tail piece 13 in fixed position with respect to each other. The tail piece 13 is provided with a plurality of parallelly arranged corrugations 16 extending, in the case shown, longitudinally thereof but which may, if desired, extend 'ransversely thereof. The tail piece 18 is utilized as an element in the manufacture of the loom picker and occupies a position in a molding device (not shown) and about which the leather forming the picker 10 is molded. During the molding process, the comparatively soft leather material is forced into the corrugations 16 and forms a secure binding surface between the tailpiece l3 and the body of the picker 1O. In practice', 17 is the striking face of the picker 10,

which is held on the picker stick 12 by a screw 18 and it has been found to be a fact that the corrugations 16 aid materially in the building of a loom picker that outwears any former construction. It is found, therefore, that the entire front portion of the loom picker not only wears evenly, but being backed up by a tail piece 13 of homogenous material that is immeasurably harder than the leather forming the body of the picker,

there-is no tendency on the part of the shut V tle to cause a shattering of the leather mai so terial or of the tail piece.

Having thus described my invention, What I claim as new is: 7

An improved loom picker comprising a plurality of convolutions of porous and resilient material One convolution of which defines an internal passage and having secured at one side of said passage a tail piece of fibrous material impregnated with an adhesive thermo plastic binder and provided with a plurality of corrugations. I

' V In testimony whereof, I have signed m name to this specification.
