1 Claim. (Cl. 13S- 157) 1 This invention relates to a picker stick for looms and more especially to a picker stick having the desired strengthand at the same time,

ythe desired resiliency to Vproperly receive and expel the shuttle, and one which will have long life and will not easily split or become damaged due to the excessive strains placed thereon.

It is an object of this invention to provide a picker stick having a reinforcing member of a different material from that from which the picker stick is made to thereby give the desired resiliency and strength to the picker stick, the thickness of the reinforcing member as well'as the length of the reinforcing member being 'capable of being varied to thereby provide from a single blank picker stick, different types of picker sticks of different resiliencies to t into various particular types of looms requiring a picker stick having a denite amount of'resiliency as well vas the required strength- It is another object of this invention to provide' an improved reinforced picker stick comprising a piece of suitable wood having a slot therein terminating short of theV ends of the picker stick, with a reinforcing member glued into this` slot which produces a picker stick having more than twice as much the strength as an all wood picker stick would have, and therefore will last longer than the ordinary wood pickel` stick and produces a picker stick which has increased strength and wearing lqualities, but does not have any less resiliency or elasticity as the original resiliency and strength of the wood is retained. i

Some of the' objects of the invention having been stated, other obiects'will appear as the description proceeds, when taken in connection with the accompanying drawings, in which- Flgure 1 is a side elevation of the improved picker stick;

Figure 2 is a front elevation of the picker stick looking from the righthand side of Figure 1;

Figure 3 is an elevational view similar to Figure 1, but showing a portion ofthe picker stick broken away;

Figure 4 is an elevation of the reinforcing strip disassociated from the picker stick;

' shown. This picker stick has extending from near the upper end lto near the hole II, alongitudinally extending and inwardly and outwardly extending slot I2 into which is adapted to be inserted a reinforcing member I4, the reinforcing mem-ber having a plurality of holes I5 therein, and this reinforcing member is preferably of -fibrous material and is a tough, hom-like material made of cellulose,` and chemically converted into a hard, vulcanized fiber with a density of from 1.20 to 1.35 as compared to wood. The

upper and lower ends of the reinforcing member I4 have notches I1 and I8 therein and before the member Il is inserted into theslot in Figure 6, it is coated on both sides and ends with a waterproof adhesive such as glue, and this adhesiveA also lodges in thevholes I5 and in the notches I1 and I8, and the ends of the member I 4 are cut to exactly t\the ends of the slot in the picker 0 stick and then the fibrous member, with its coating I9 of adhesive disposed on the sides thereoil and in the holes I5, and notches Il and I8, is inserted into the slot as a tight iit and then the picker stick is subjected to a. heat treatment of 5 approximately 110 degrees Fahrenheit for a period Y which hasvall the desired resiliency of a conven- Figure 5 is an elevational view with parts broken away of the upper end of the picker stick; Figure 6 is a. cross sectional view takenalong the line 5 6 in Figure 1.

Referring more specifically to the drawings,

tional picker stick made of hickory or similar wood, and at the same time, provides a picker stick which is many times stronger than the conventional picker stick made from a. solid piece of wood.

In the drawings and specifications, there has been set forth a preferred embodiment oi.' the invention, and although specific terms are emplayed, they are used in a generic and descriptive sense only, and not for the purpose of limitation, the scope of the invention being defined in the claim.

We claim: 4 v

A picker stick comprising a piece of wood, hav ing a slot extending longitudinallythereot and stopping short of the ends of the picker stick, said slot being cut all the way from the outer edge of the picker stick to the inner edge thereof, and

3 e reinforcing member of compressed brous ma.- terial completely illling said slot and adhesively bonded to the wooden portion of. the picker stick,

said reinforcing member having cavities therein for receiving adhesive material.
