PICKER STICK FOR LOOMS.

Application filed March 25, 1927. Serial No. 178,400.

This invention relates to new and useful unprovements 1n picker supporting dev1ces for looms, and the object of the invention is to provide a strong and durable picker sup port which will be inexpensive to manufacture and maintain in operation.

A further object is to provide a support which will not be affected by atmospheric chain 111 the mill.

The picker supports at present in use are usually made of selected wood which must.

be of straight grain. These supports or sticks before being put into operation are subjected to a very severe test against warping, and the sticks which do not pass this'test are destroyed. It will be seen that thiscondition tends to keep the price of these sticks very high.

in my invention I overcome the above objections by forming the supports for the pick of thin metal tubing, or drawn steel, which has not the same tendency to get out of shape during the operation of the loom.

In the drawings which illustrate my improved type of picker support in different forms;

Figure 1 is a partial side elevation of a picker support with the picker (shown in dotted lines) attached thereto.

Figure 2 is a partial plan of the support shown in Figure 1,

Figure vation of Figure v Figrue is an enlarged sectional end clera on of the support taken on the line l l igu re 1.

Figure 5 is a side elevation of a modified type of support.

Figure 6 is a sectional end elevation taken on the line 66 Figure 5.

Figure '7 is an end elevation of the shown in Figure 5.

Referring more particularly to the drawthe support taken on the line 33 support ings, 11 designates my preferred form of" picker stick, or support, which ismade from a metallic tube of rectangular cross section,

as shown in Figures 3 and 4. The support is 3 is an enlarged sectional end elelllHXllI'lUDl strain due to bending,

end 15. The picker 18, which may be of any desired form, is secured to the smaller end 15. The end ll is provided with an aperture 19, through which a bolt, or such like fastendevice, is passed to secure the support to a rocker-beam in theusual manner.

1 In the form shown in Figures 5 to 7 inclusive, the end 15" made of round tubular cross section and the picker,18is placed between a pair of spaced collars 20, which are pressed vor forced on to the end of this support. The remainder of the support is made of rectangular tubular cross section with the sides 12 and 13 tapering outwardly to wards a portion 21, in proximity to the end lat. The sides 12 and 13 are made with their edges parallel to one another from the portion 21 to the end 14*.

I do not desire to he understood as limiting myself to the types of supports shown in same manner as the wooden type of support or stick at present in use. tapering the support in the mannerherein described, the picker support is constructed to resist the as the greater depth at the end remote from the picker is the point where maximum bending occurs duringthe operajttion of the loom; It

" will be readily seen that a support made of thin metallic tubing tapering from one end to the other canbe made resilient to absorb the shock or force exerted on the picker and its support when flying or driving a shuttle.

'Having thus described my invention, what I claim is i As a new article of manufacture, a picker stick consisting wholly of a hollow drawn ,metal tube having a body portion of rectangular cross section gradually tapering toward one end and provided at sald end with an integral extension of circular cross section adapted to receive a picker.

In witness whereof, I have hereunto set,

my hand.
