Application December 12, 1931 Serial No. .580,717

3y Claims. (Cl. 139-146) This invention relates to picker sticksfor looms.

The primary object of this invention is to provide a ,picker stick of the above mentioned :character having certain novel and new characteristics which will endure a great amount of v service in the environment in which-it is used thereby eliminating the possibility of breakage and the resultant repair work causing the stopping ofthe loom and loss of time. Y

A further object of this invention is to provide a picker stick for looms having a new and novel heel strap connection at the lower end thereof fastened in such a manner as to eliminate the use of screws, nuts and bolts or other metallic fastening means which 'frequently become loose and cause considerable damage to the operation ofv the loom on which the'picker stick is employed. y

A still further object of this invention 4is to provide a lug strap support for a picker stick4 which may be detachably secured thereto in an adjustable Vfashion in order that the power applied to the shuttlemay be increased or deil creased without necessitating the use of tools andthe waste of time for making the necessary adjustments.. y

A still further object of this invention is to provide a guard'at the upper end of the picker ystick to prevent the wear to which this end of the picker stick is subjected during the operation of the loom and thereby `eliminating the necessary tvirne'and work required to replace a picker stick .in a loom, said guard being secured to said 'stick'without weakening 'the latter. Y

A still further object of this invention is to provide a picker stick for looms in which the use of nuts, bolts kand screws is entirely eliminated, thereby removing the diiiiculty heretofore eX- .perienced in loom picker sticks due to the nuts and bolts or other fastening devices employed becoming loosened due to the shocks encountered by the picker stick when the stick strikes.

A still further object of this invention, is to Lprovide a picker stick for looms which is comparatively cheap to manufacture and which has picker stick embodying this invention;

Figure 9 is an enlarged fragmentary 'edge view ofthe heel `portion of the picker stick illustrating the grooved end portion illustrated in dotted linesin Figure v8; and

In the drawings, wherein for the purpose'nof' illustrating the invention and wherein like refer-v ence characters will be employed to designate like parts throughout the same, the reference character 5 in Figures 1 to inclusve will gen'-, erallybe employed to designate a picker stick for looms havingv the usual shuttle engaging strap 6 slidably mounted on the. upper end there-v of. It is proposed to form the picker stick 5 of wood or other fibrous material and secured tothe upper end is a metal bar 7 secured tol one edge of the picker stick by wrappin'gs 8 of wire, twine or cat gut. The metal bar 7 is preferably or" cylindrical formation as shown in Figures 1,

of the hei '2 and 3 and if desired, the lower end of the metal rod 7 may have its end bent as at 9 to be received in an opening in the upper end of the picker stick therebyipreventing sliding movement or displacement of the metal guard from its position. In order to prevent the lateral displacement of the guard rod 7, the edge of the picker stick adjacent the upper end is grooved as at 10 so that the rod 7 may rest therein and be held in place by means of the wrapping 8 above discussed.

The lower end of the picker stick 5 is curved in the usual manner as at 1l and is provided with a vertical slot 12 extending a short distance into the ends of the picker stick and terminating in a curved portion '13. The lower end of the slots 12 communicate with a transverse cut away portion 14 clearly shown in Figure 6, and extending downwardly from the transverse cut away portion 14 is a groove as at 15, illustrated clearly in Figure 5 and shown by dotted lines in Figure 6. The slot 12 is adapted to receive one end of a heel strap as shown in Figure 1 and said heel strap is more clearly shown in Figure '7 as being provided withV a section 16 secured to the main body portion 17 of the heel strap by means of rivets 18. Extendof the heel strap 17 is an extension 19 which is adapted to be received in the groove formed- 16 abuts against the lower transverse edge21 ofthe'transverse cut away portion 14 and the opposite portion of the attached section 16 extends upwardly into the slots 12 and abuts against the terminal 13 as shown in Figure 1. At the opposite end of the Vheel strap 17, there maybe provided a lslot 22 for receiving the usual coil spring whereby the`picker stick vwill normally be moved in aV clockwise direction on the pivot bolt 23. l -In Figures 8, 9 and 10, vthere is illustrated modified form of heel strap connection and the lower end of the picker stick 11' is provided with a dove-tail slot l2 havinga lower curved edge 25 and a complementary curved section 26. i The extreme lower portion of the heel 'is slotted as at l5 for receiving a projection 27 formed on the modified form of'heel strap 17y shown in Figure 10, -The heel strap is provided at 4., one'end with the usual'spring receiving slot 22' while the opposite endis bent upon itselfas at 16'Y to` form an enlarged portion adapted to be received in'theV dove-tail slot'1'2 as clearly illustrated in Figure 8. l

Attention is now directed to Figures 1 and 4, wherein is shown a' lug strap support comprising a pair of leather straps and 31 secured together at the top and'bottom edges as at 32 and 33. straps 30 and 31 are separable for the purpose of receiving the lug straps on the end of the picker stick operating lever (not shown) vA series` of pins 34 having enlarged heads 35 pass through openings in the inner strap 31 and are adapted to aline with a plurality' of equally spacedopenings 36 so that the lugr straps formed by the sections 30 and 31 may be moved up and down' relative to the picker stick 5. In practice, the lug strap passes through the space between the straps 30 and '31 and encircles the ing from the portion 16 toward the opposite end Y ure 1, the shoulder 2O of the attached YsectionV The intermediate Vportions of the lugV picker stick 5 in a manner well known in the art.

It is to be understood, that any number of pins 34 having enlarged heads 35 may be secured to the section 31 of the lug strap supporter in such a manner that they aline with the holes 36 formed in one edge of the picker stick 5. It is quite obvious, that the lug strap supporter may be moved up or down relative to the picker stick in order to make the necessary adjustments for the increase or decrease of power applied to the shuttle without requiring the use of tools and lengthy manipulation for making the required adjustments.

It is to be understood, that the form of the invention herewith shown and described is to be taken as a preferred example of the same and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the sub-joined claims.
