BECKER STICK.

Application filed June 19, 1924; Serial No. 720,955;

To all whom it may 00mm:

Be it known that we, DANIEL A. KEATING and Jaime B. T ATEM, citizens of the United States residing at Bridgeport and lutnam, respectively, in the counties of Fairfield and l finclliam respectively, and State of Con necticut, have invented certain new and useful Improvements in Picker Sticks of which i the following is a specification.

This invention relates to an improved construction of combined wood and metal picker stick of the type employed for driv ing the shuttle across a loom; and the objeet or this'invention is to provide'a picker stick of this character having itsupper portion of wood and its lower portion of metal, the wood providing the necessary resiliency for receiving and throwing the shuttle across the loom while the lower portion provides additional strength to that portion which is usually the first to become broken where an all wooden stick is employed.

A further object of this'invention is to form the upper portion of Wood and the lower portion of two opposite side plates bolted or otherwise secured to the sides of the wooden portion to simplify construction of this metal portion of the picker stick and at the same time provide greater strength to that portion which ordinarily is the first to break.

A still further object of this invention is the provision of a relatively short filler or spacing member for spacing the lower ends of the side plates and to provide a suitable bearing for the pivot pin on which the picker stick may oscillate if it is d'esired' to mount it upon a pin for this purpose. With these and other objects iniview, the invention consists of certain novel features or construction, as will be more't'ully de scribed, and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a side elevation of our improved picker stick showing the upper portion of wood and the lower portion formed of metal side plates fastened tothe Wood.

Figure 2 is an edge view of our improved construction of picker stick showing the side plates as fastened to the sides of the wooden portion.

Figures 3 and 4 show constructions Whereby the opposite side plates are formed of shallow channel members bolted to opposite sides of the wooden portion and having a tubular spacer their lower ends.

Figure 5 is a section on line 5-'5 of F lg ure 3 showing the end Or the wooden mem her as secured between the side plates.

l igure 6 is a section on line 6 6'oi:' F 1g ure 4-, showing a deep flange on one of the side plates providing a backing for the at tachment of the operating member.

Figure 7 is asectional View on line 7 7 of Figure 3, showing a spacer member as formed on a short length of tubing riveted to the opposite side plates. 'i v The operating life of anordinary wooden picker stick as well known, is very short. It is also knownthat a picker stick requires a certain amount of resiliency or spring in orderto properly act upon and throw the shuttle across a looin and, therefore, in order to strengthenthat portion of the stick which ordinarily breaks first and at the same time obtain the necessary yieldability, we have formed a picker stick with its u per portion of wood, by which we obtaintlie necessary elasticity and its lower portion of metal by which we obtain the strength required to withstand the extreme'h'ard usage to which the pickerstick is subjected,"- andthe following is a detailed description of one embodiment of our present invention by which these advantageous results may be accomplished.

lVith reterenoe" to the drawings, 10 designates the upper portion of our improved construction of picker stick which is formed of Wood, usually hickory, the same being preferably rectangular in cross section, larger at the bottom portion 12 and tapered towards its smaller, upper portion 13. p

The lower portion of this stick is herein shown as being formed of tWo side plates 14 and bolted to the opposite sides of the lower portion of the wooden member 10 by a plurality of bolts or rivets 15, a spacer jrnember 16 being placed between the lower ends of these side plates which may be formed of a block or wood 17 such as ligniimjjvitae or other woods of the necessary hardness to withstand the required strains, or any other suitable material may be employed; and

or EUTN'AM, ooivninorr-' & STAMPING COMPANY.

when such a block is employed it may be secured by means of bolts or rivets 18 or any other suitable means.

In some instances, instead of employing the plain, ordinary side plates 1 1 for the lower portion of the picker stick, we may form these side plates 19, as illustrated in Figures 3 to 7, inclusive, each with narrow edge flanges 20 which perform the double function of lateral strengthening of the side plates permitting them to be made of thinner material and also providing a support for the front and rear edges of the wooden portion of the stick as at 21 against the thrust or the blow of the shuttle upon it thereby reducing the number of fastening bolts 22 required, over the number required in the construction of peak side plates, illustrated in Figures 1 and 2.

In some instances, instead of the block of wood 16, as illustrated in Figures 1 and 2, to perform the functions of a spacer, we pierce the side plates as at 23 and insert a short length of tubing 24 having a shoulder with extending portion 25 which are swaged, upset, or riveted into chamfered holes in the side plates to securely lock these ends of the plates together and at the same time provide a suitable, continuous bearing between the side plates for the pivot pin on which the picker stick may oscillate.

In some instances, we provide a tapered flange portion 26 on one of the flanged side plates to form a support through which to attach the operating mechanism. I

In some instances, we permit the side walls of the side plates to extend beyond the flanged portions 20, whereby a recess is provided for the reception of a return strap (not shown).

We do not wish to be limited to mounting our improved picker stick to oscillate upon a pivot pin as other suitable means for supporting the lower end, may be employed. Our improved construction of picker stick is extremely simple and inexpensive to manufacture and by its use we provide the necessary resiliency for the throwing of the shuttle and also the necessary strength of that portion of the stick which ordinarily breaks first. 1

The foregoing description is directed solely towards the construction illustrated, but we desire it to be understood that we reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

We claim:

1. A picker stick having substantially its upper half of wood and substantially its lower half of two separate lengths of spacedapart oppositely-disposed metal side plates, said plates being supported in spaced relation at their opposite ends and disposed in substantially parallel relation throughout their length.

2. A picker stick having substantially its upper half of wood and substantially its lower half formed of two separate lengths of spaced apart oppositely-disposed substantially parallel metal side plates, the upper ends of said plates being secured to opposite sides of the lower end portion of the wooden member, and aspacer member of substantially the same thickness as that of said upper end member for supporting the lower ends. of said plate in spaced relation.

3. A picker stick having substantially its upper half of wood and substantially its lower half of two separate lengths of oppositely-disposed substantially parallel spaced-apart metal side plates, the upper ends of said plates being secured to opposite sides of the lower end portion of the wooden member and having a spacer bearing member secured between their lower ends.
