Patented May 9, 1922.

Application filed October 3, 1921. Serial No. 504,971.

, certain new and useful Improvements in Loom Pickers, specification, reference being had to the accompanying drawings. I

This invention relates to loom pickers, that is to cushioning members mounted upon the extremities of the picker stick of a loom and with which the point of the shuttle the body or shell provide is adapted to engage when the. picker stick strikes the shuttle.

The general object of our invention is to provide a loom picker whichhas been found particularly effective in actual practice, which is strong, which will last for a considerable time, and which may be readily applied to the standard picker stick.

A particular object of the invention is to a novel and improved device of this general character comprising a body of metal, such as aluminum, provided with a chamber in which the hunter and its associated partsare arranged, the metal body serving to prevent distortion of the hunter so that the vibration of the shuttle as the result of a distorted bunter is avoided.

A further object is to provide a picker of this character comprising a hollow body formed to slip over the picker stick and provided with screws whereby it may be engaged with the picker stick, this hollow body 'being filled with leather scraps or leather cushioning material.

Other objects have to do with-the details of construction and arrangement of parts as will appear more fully hereinafter.

Our invention is illustrated in theaccompanying drawings, wherein:

Figure 1 is a side elevation of a portion of apicker stick with our improved picker applied thereto; i

Figure 2 is a longitudinal horizontal section of the picker and stick;

Figure 3 is a front elevation of the body or shell of the picker, the hunter being omitted.

Referring to these drawings, 10 designates preferably made of aluminum and which is preferably, though not necessarily, octagonal in cross section. Extending inwar from. one end of the body 10 is a bore 11 Donors and of which the following is a of the picker which is constituting a chamber, this bore at its rear end being intersected by an aperture 12, through which the picker stick 13 is disposed. This aperture 12 .is rectangular in cross section, while the chamber 11 is circular in cross section, the aperture for the picker stick being less in width than the diameter of the circular chamber 11, leaving 1 two shoulders 14 on each side of the intersection of the chamber 11 with the aperture or plassage12. At the mouth or open end of t e body 10 the interior face of the body 1s formed to provide an annular recess 15 and the forward wall of this recess extends centrally inward, as at 16, beyond the in ner face of the bore 11 so that the aperture 17 defined by said projecting wall 16 is less in diameter than the diameter of the chamber 11. ,The outer face of this wall 16 is beveled outward and forward or preferably concavely curved outward and forward, as at 18.

Viewedin plan, it will be seen that'the rear end of the picker is circular in form, as at 19, and countersunk apertures 20 are provided on each side of the body which open into the passage 12 for the picker stick. These apertures are countersunk for the introduction of wood screws which engage the icker stick 13, these screws being designated 21. The picker stick 13 is illustrated as of standard character and rectangular in cross section, the rear face of the picker stick extending upward and toward the forward face so that the passage 12 smaller in cross sectional area at its upper end than it is at the lower end. The interior of the body 10 is to be filled with leather scraps,

designated generally 22, and the recess 15 is to receive a rim 23 which holds these scraps in place, the margin of this rim or holding member 23 being inserted and forced is formed of old scrapped leather rather The inwardly extendthan new leather.

the leather ing flange or wall 16 prevents coming out of the body 10.

The filling or hunter preferably comprises scrap leather cut into Washer form, said washers being glued or otherwise secured to d' each other so that the filling or bunter may be readily seated within the chamber 11 inthat the shuttle strikes when 17 defined by the wall 16.

The rim 23 is also of washer formation with the central opening 23 thereof preferably of a diameter in excess of the bore 22 of the filling or bunter. The opening 23* is adapted to receive the point of the shuttle and in applying the picker upon. the stick, the picker is adjusted by the operator to bring it into such posit1on to assure the point of the shuttle being received within p the body 10 protects the shuttle while'it is the opening 23. This assures the action of the shuttle itself expanding both the bunter 22 and more particularly the rim or holding 'member 23 so that the maintenance of the bunter and the rim in applied position is assured and particularly asthe material of said bunter or rim wears. In view of this, our improved picker possessessubstantially the same degree of efliciency in, say, a year s time as when it was first used.

The concave depression 18 in the wall of functioning. The relatively thick wall exterior to this depressed portlon 18 reinforces the picker at this point. The shoulders 14 support the hunter or leather plug. By connter-sinking the aperture 20 for the wood screws, the threads of these screws are prevented from being broken. The screw is entirely encased by the metal so that there is no chance for the screw or its threads to become broken. The wall which surrounds the leather is relatively thick so that it prevents the leather from getting out of shape and holds it in position when the cushion impinges against the extremity of the shuttle. By this device we secure all the life in the leather and inthe picker stick and the device cushions or softens the contact of the shuttle with the picker stick and thus prevents the picker stick from breakin As before remarked, this body is pre erably made of aluminum because it is light in weight and this lightness tends to protect the icker stick from breaking.

e also find it of advantage to have the body 10 of the picker octagonal or other wise angular in cross section as this provides a flattened side face a riding over the strap of the adjacent binder without unduly wearing or scratching the strap. In the operation of the loom, this is of material importance and advantage as it avoids the vibration of the picker which would otherwise occur should the strap of the binder be scratched or otherwise roughened.

It is also to be particularly noted that the heads of the wood screws 21 are countersunk in the body 10 ofthe picker, so that said screws, when applied, do not extend beyond the surfaces of the body. The advantage of this resides in the fact that there is no part of eachof the screws extending outwardly of the'body which would be liable to break the thread or scratch the leather.

We claim:

A picker of the character described'comprising a body formed with a longitudinally extending chamber opening at one; end of the body and with a picker stick passage extending transversely through the rear end of the body and intersecting the rear end of the chamber, the chamber having a diameter greater than the.width of the picker stick assage, the forward end of the chamber aving an annular recess defined at its forward end by an inwardly projecting annular wall, the interior diameter of this wall being smaller than the interior diameter of the ing outwardly and forwardly flared, a filler disposed within said chamber, and a holding rim, the peripheral portion of said rim seating within the annular recess, whereby said rim holds the filler in the chamber, the filler having an opening substantially centrally thereof, the opening defined by the rim being of greater diameter than the diameter of the opening in the filler, the side and inner end walls of the chamber being imperforate, the stick to which the'picker'is applied being comprised in the inner wall of the chamber.

.chamber and the outer face of this wall be- In testimony whereof we hereunto aflix our signatures.
