Worth Ga. Payne; Greensboro,g N.` (1. assigner: of
ten .per cent-.to .Zachariali-.Ht Hooverton, Sr.,-. and` ten per. cent to Frank JT. Robinson, both of' Greensboro, N1 Cif Applcationi November 8, 1948Seri'alz`No. 58,904.
Thisv` inventionl relates` tol a4 picker stickl and mounting therefor and.'` moreY particularly to a picker` stick. which` may beiv made4 from :metal and thelike. p v v Among they iactorstwhich: haveV impeded the adoption: of metal. picker'sticks are;, the: liability of injury to the loom.. mechanism-f.shouldthe picker stick encounter an obstructionk during its .movement under the.- iniiuenceA of; the: powerstrap ol` the loom, andv the-` liability of the metal. to crystallize under the effects of thershock caused bythe'sha-rp and rapid. impacts! to `which picker sticks; arefsubjected when inservice.
The primary objectif ott this'. invention. is to protect they mechanism of.. a. loorn: from injury should a pickerv stick thereof meet.. arr obstruction. dur.- ing.;` itsmovementl to and fro` in.. the: shuttle: box of. the'loom.
Another important;` object is toirendenfeasible the use of. metal picker sticks: in loomsandi to remove as far asl possible. at` least one-` of: the. major factors which produce crystallization in. such sticks.
The; above:` andother;` objectsmay be attained by employing this` invention which; embodies amongv its features." a-v laterally extending. stud mounted on a. loom. parallel,v alpickeir` stick. having a notch-l opening, through. one e'dgef near' its lower end: for: receiving.' the;l stud4 and;A pivotalfly supporting theipicker stick on. saidzparallel and means: on the'picker.` stick closing: the; open: end of. the notch and` movable automatically out ot notch closingspositionuwhenthelnormal movement. of the picker stickis. obstructed..
Other features.includefaryoke. pivotally mounted on the picker stick near the notch, a shoe carriedby theyoke'andmovable therewith into and out of notch closing positiomand yielding means connected tothe yokeV and tothe picker stick to hold.- theshoe in notch. closingl position.
Still other features include. ay cylindrical cushion mounted on the stud for rotation about the axis thereof, a picker stick" having a notch opening` through one edgev adjacent the. lower end thereof, said notch receiving` the stud. rockably to support. the, picker stick` on the loom parallel and means on the picker stick closing the open end of the notch and movable automatically of the notch closing position when the normal movement of the picker stick is ob structed.

Figure 2 is a side view of the picker stick i1- lustrated in Figure 1, and showing it dismounted from the cushioned stud, as when meeting an obstruction in the loom box;
Eig-ure 3 is aV rear. edgeA view of: ay pickerv stick embodyingl the: featuresA of. this invention;

Referring tothe drawings in, detaiLa picker stick. designated generallyl Ill comprisesA an elongated body l2' equipped atits upper endlwith conventional means for supporting a loom picker. Thepickerfstick isenlarged as` at' i4 adjacent its lowerA end, andentering theedge-.of the body |l2I directlyopposite the enlargement I 4 is a not-ch it; for." the reception. of.A the mounting. stud about which the picker stickpivots. The body I 2 of the picker stick Ulis` preferably cast of alight metalsuch as aluminum', magnesium or thef like; and is equippedv with conventional power strap attaching; means` t8 and returnv strap attaching means 2l)y by which the.1 picker, stick is rocked about the axis of its pivot.
Mounted on, tlfie` conventional rocker shaftfof the loom-'is a loom parallel` designated. generally 221Which is providedwith a horizontally extend;- ing arm 24: having an elongated.longitudinal,y slot Zlformed therein for the reception of theo-mounting stud 28 of the picker stick. This. mounting stud is held in various adjusted: positions. in` the slot 26 by meansv of a conventional clamnnut 30; andfextends perpendicular. from the armv .'lllalong ai substantially horizontal axis.V Surrounding. the stud 28 is'a' bearing sleeve 32,.and encircling the bearing sleeve is a cylindrical cushion 34E which is preferably formed of rubber.' or.' other" suitable yielding. material. The cushion 34 is'4 held in place between the head of the stud 28,' and the arm: 242,, and. formsY theV surface which contacts thetwallsf ofthez notch I6;- pivotally to support thet pickerfstick one` the stud; The cushion 341 is preferably substantially equal: in` diameter'to the widtha` of' they notcl'fr. l t.. so: as to'. form. a snug' fit be.- tween:v the parts for the* purpose: of: accurately supportingV the: picker. stick in position. on` the loom` In order releasably to secure the picker stick I0 in place on the cushioned stud 28 I provide a retaining member or yoke designated generally 36 which comprises substantially U-shaped arms 38 which are pivotally supported as at 40 on the picker stick through hole 4| on the yoke directly above the axis of the inner end of the recess or notch IB. The arms 38 of the yoke 36 embrace the picker stick as will be readily understood upon reference to the drawings, and provided at the ends the arms remote from the bight portion of the yoke are downwardly extending hooks 42 carrying a curved shoe 44 which, as illustrated in Figure 4. is adapted to enter the slot or notch I6 3 to bear against the cushion 34 and hold the picker stick on the stud 28. One end of a retractile coil spring 46 is coupled to the bight portion of the yoke 36 through hole 5I, while its opposite end is adjustably connected as at 48 to a bracket 50 carried by the body I2 of the picker stick I0 in upwardly spaced relation to the enlarged portion I4 of the picker stick. The spring 46 serves to retain the shoe 44 in contact with the cushion end of the notch I6 before any damage can be .v
done to the loom. The opening of the notch will cause the picker stick to fulcrum about the obstruction at its upper end, and throw its lower end off of the stud by moving the stud through the end of the notch I6, as suggested in Figure 2. By thus disconnecting the picker stick from its normal pivot, it will be obvious that danger of injury to the loom will be avoided. At the same time, when the trouble has been corrected, the picker stick may be remounted on the stud simply by causing the stud to be received in the slot or notch I6 while the shoe 44 is held out of slot closing position against the influence of the spring 46. As soon as the spring 46 is released, however, it will be obvious that the shoe will swing downwardly under the eiort of the spring to close the end of the slot and hence restore the parts to working order.
Obviously, the restoration of the loom to a production basis requires but a few minutes, as no adjustment of the pivot of the picker stick needs to be made. Obviously, the picker stick may be restored to its pivotal support with but a minimum of effort.
While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that minor changes in the details of construction and arrangement of parts may be resorted to without departing from the spirit and scope of the in- 4 position when the normal movement of the picker stick is obstructed.

A picker stick and mounting therefor comprising a laterally extending stud mounted on a loom parallel, a picker stick having a notch opening through one edge near its lower end for receiving the stud and pivotally supporting the picker stick on said parallel, a yoke pivotally mounted on the picker stick near the notch, a shoe carried by the yoke and movable therewith into and out of notch closing position and yielding means connected to the yoke and to the picker stick to hold the shoe in notch closing position.
3. A picker stick and mounting therefor comprising a laterally extending stud mounted on a. loom parallel, a cylindrical cushion mounted on said stud for rotation about the axis thereof, a picker stick having a notch opening through one edge adjacent its lower end, said notch receiving the stud rockably to support the picker stick on the loom parallel and means on the picker stick closing the open end of the notch and movable automatically out of notch closing position when the normal movement of the picker stick is obstructed.
