To @ZZ whom t may concern:

Be it known that we, DANIEL A. KEATLNG and JAMES TATEM, citizens of the United States, residing at Bridgeport and Putnam, respectively, in the counties of Fairfield and Windham, respectively, and State of Connecticut, have invented certain new and uscful :improvements in Picker Sticks, of which the following is a specification.

This invention relates to an improved` construction of Vcombination wood and metal picker stick of the type employed to drive the shuttle .across a loom; and the object of this invention is to provide a picker stick u of this character having its upper portion of wood and its lower portion of metal in tubular form thereby obtaining the required resiliency of the wood and at the same time obtaining the increased strength of the metal for absorbing the hammer-like shocks of the shuttle in receiving and throwing the shuttle across the loom. y y

A furtherobject of this invention is to form the upper end of the tubular metal portion to provide a socket for the reception of the lower end of the wooden portion, also where the stick is pivotally. mounted to pierce the side wallsnear the'lower portion of the tubing forming inwardly-proyecting iianges about the hole to receive the pivot pin on which the device may swing.,

lVitlithese and other objects in view, theV invention consists of certain novel features of construction, as will bc more fully .described, and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure l is a side elevation of our improved combination wood and metal picker stick, showing the lower end of the wooden portion as inserted into the tubular upper end of the metal portion.

Figure 2 is an edge view of the picker stick.

Figure 3 is an enlargedsection on line 3 3 of Figure 1, showing the metal tubular portion as folded into rectangular shape..

Figure l is a section on line t-t of Figure 1, showing the inturned stock of the side walls about the pivot pin to form extended bearings therefor.

1t is found in the practical construction and operation of picker sticks for looms that, when made entirely of wood their operlating life, owing to the severe hammering treatment to which they are subjected, is very short. lt is also found that in securing the strength of an all-metal picker stick it must also be extremely light andat the same time should have the resiliency or substantial yieldability of the all-wooden picker stick which is usually formed of hickory.

Therefore, in order to combine these requirements of strength and yieldability. we have formed a picker stick of combined metal and wood, the wood providing the elasticity while the metal provides the necessary strength about those portions where this greater. strength is required. l.

By this construction, when one portion of the stick is broken and thrown away the unbroken portion can be remounted in the fresh portion; and the following -is a detailed description of one embodiment of our present invention by which these advantageous results may be accomplished:

With reference to the drawings, lO-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 its lower end and tapering towards its outer end. This wooden portion is preferably formed of a length substantially one half that of the entire stick but its length may be of any desired proportion thereof.

The lower portion ofv this stick is herein shown as being made in tubular form as at 11 and the tube may be made in any'desired manner and of any desired shape in cross section, but we preferably form the same of sheet metal andfold this metal to form side walls 12 and edge walls 13 and 14, rectanguvlar in cross section. The edges of the strip of metal are caused to abutat 15 along the length of the tube to form the edge wall 14 thereof. n

The upper end of this tube is shaped to provide a socket for the correspondingly 18 and turned thenstock inwardly about the piercing as at 1.7 'forming elongated bearing portions for the reception oit the pivot pin (not shown) on which the picker stick oscillates when or" the type to loe mounted on a pin for this purpose.

ln some instances, we'also 'torni the side walls l2 a little longer than the edge walls 13 and lll thereby providinga groove or recess 19 in the end or' the metal porti-on for the reception of the return strap (not shown).

N ear the upper end oi the metal portion, we have also provided a series ot holes 2O to which the operating mechanism may be connected.

lVe 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 picker stick is extremely simple and practical in construction and eiective in its operation and its working life is much longer than that of the allwood picker stick and at the same time will give the required resiliency which has heretofore been obtained by an all-wooden picker stick.

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

No claim:

l. A picker stick having its upper portion 'of wood and its lower portion formed of a. single piece oi" metal in tubular -form throughout its length.

2. picker stick having its upper portion of wood and its lowei` portion of a single piece ot sheet metal folded into tubular form.

A picker stick having its upper portion oil wood and its lower portion of a single piece of sheet metal folded into tubular form angular in cross section througlout its length. y

4l. A picker stick having substantially its upper halt ot wood and its lower half of a single piece of sheet metal folded into tubular form angular in` cross section threugl s out its length, its opposite side walls being pierced to. receive a pivot pin.

5. A picker stick having its upper porn tion of wood and its lower portion formed of a single piece ott metal, of tubular form throughout its length formed to provide a socket at its uppe1 end, for the wood, and spaced apart side walls at its lower end pierced to provide bearings for the pivot Pm" 6. A picker stick having its upper portion ol wood and its lower portion of a single piece o'l metal in tubular form,v the upper end of the tube Vbeing 'formed to receive and closely embrace the lower end or' the wood, and its lower end having its opposite walls pierced to receive and provide a bearing for a pivot pin.

A picker stick having its upper portion or wood and its lower portion Vot sheet metal folded into tubular Jiform, the upper end or' the tube being tormed'to receive and closely embrace'the lower portion of the wood and the walls of its lower portion bepiereed to receive a pivot pin.

8. A picker stick having its upper portion oitl wood and its lower portion of sheet metal folded into a tube rectangular in cross section and formed at its upper end to receive the end of the wood and the Vside walls or" its lower portion being pierced to receive the pivot pin.

9. A picker stick having substantially its upper halt ot wood and substantially its lower half of sheet metal folded into tubular form, the upper endv oli' the tube being formed to receive the wood and the wallsV adjacent its lower end being `pierced' and the stock turned inward about the piercing to provide an elongatedl bearing for the pivot pin. l0.
