PICKER-STICK BUN'TER.

SPECIFIOATIN forming part of Letters Patent No. 727,859, dated May( 12, 1903. l

l Application filed October 22, 1902. Serial No. 128,279. (No model.)

ter described, and more particularly pointed'- out in the claims at the end of this specification;

In the accompanying drawings, Figure lis a front view of sufcient parts of a loom to illustrate the application of my invention thereto. Fig. 2 is an enlarged side view of the attachment, and Fig. 3 is a front View thereof.

In the ordinary loom picker-sticks are employed for throwing the shuttles from one side of the loom to the other. These pickersticks are mounted to swing back and forth with the lathe. Each picker-stick is given its inward or operating throw by means of a sweepstrap,and each picker-stick is returned to normal position by a spring. In practice some means are required to limit the operating stroke of a picker-stick. On most of the modern looms the operating stroke of each picker-stick is limited by a stop or bunter carried by the lathe. The use of a stop or bunter mounted on the lathe is objectionable, as it adds a certain amount of weight to a moving part, While the swinging motion of the lathe itself increases the jar or shock to which the bunter is subjected, so that the same is more liable to be jarred" out of position. In the older typeof looms the operating stroke of thepickenstickis usually limited byastrap or ing,which in some instances is secured to the loom-frame. The use of a Ileather strap or sling for limiting the operating stroke of a picker-stick is objectionableas a strap when employed in this location is speedily worn'out and broken. To overcome these defects, -ithas been proposed to provides'pecial stopping devices which are mounted n pon the loom-frame.` The stopping devices of this character have, however, been so complicated that they have not as yet come into general use.

The especial object of my present invention is to provide a stationary picker-stick bunter of that class adapted to be secured to the loom-frame of'snch simple, rigid, and eficient construction that it may be applied to nearly all classes of looms .and which will Wear for long periods. A

To these endsa picker-slick stop or bunter constructed according to this invention comprises a bracket and a support adjustahly secured .to the bracket, which support carries `a rubber cushioning-block which is boundin place by a leather girdle or strap.

-When the parte of a picker-sticker bunter constructed accordingr to this invention-are properly adjusted and secured together, they occupy a stationary or xed position and are not subject to the wear of moving parts.

Referring to the accompanying drawings,

A designates a lathe-frame carried by swinging arms B, journaled on shaft S. Carried by and swinging with the lathe is a pickerstick l, which is swung in on its operative stroke by a sweep-strap L and is drawn back bya return-spring R. F designates a portion. of the loom-frame. These parts may be of any of the ordinary or approved constructions and need vnot be herein described atv length.

A stop or bunter constructed according to this invention comprises a bracket or support l0, which may be secured to the loom side by bolt 11. Adjustably mounted on the bracket 10 is a support or angle-piece 12. The bracket IlO and piece 12 have intermeshing ribs, and

ber block 17 is lheld down by a stop 18, fastened by a screw 19, and is) bound onto the inclined face 15 by a leather girdle orbelt 20. The leather girdle or belt 2O provides a proper Wearingface for the bunter, and in practice a bunter of this kconstruction can be vrun for long periods of time before the leathergirdle 2O needs to be replaced. lhe practical advantages of a picket-stick bunter as thus constructed are that the bunter is less liable t0 he knocked outot' position than when secured on thc lathe or other moving part, that thc old forms of leather slings or straps are not required, and that no moving' parts, springs, sliding rods, or other pieces are employed which are liable to crystallize or be broken.

I am aware that changes may be made in practicing my invention by those who are skilled in the art without departing from the scope thereof as expressed in the claims. I do not wish, therefore, to be limited to the construction I have herein shown and described; but

What Ido claim, and desire to secure by Letters Patent of the United States, is-

l. In a loom, the combination of the frame, anda picker-stick bunter secured tothe frame to occupy a fixed or stationary posit-ion, said bunter comprising a su pporting-face, a rubber cushion, and a leathergirdle holding the cushion in place upon the supporting-surface, and furnishing a leather face against which' the pickel-stick strikes. v

2. In a loom, the combination of the frame, and apicker-stick bunter secu red to the frame to occupy stationary 0r fixed position, said bunter comprising a bracket adapted to be bolted to (the fraine, a support adjustably mounted on the bracket and having)r an inclined face, a rubber striking-cushion, and a leather girdle binding,r the rubber cushionin piace upon the inclined supporting-face, and providing a leather surface against which the picker-stick strikes.

3. As an article of manu facture, a pickersticlc bunter adapted to be secured to the loomfranle to occupy a fixed or stationary position, com prising a bracket tobe bolted tothe frame, a sul stantially I -shaped support. adjustableon said bracket, said parts havingl intel-meshing ribs, and the support havingan inclined face with a ledge orprojectiou along the lower edge thereof, a rubbercushion, and a girdle of leather binding,r the leather cushion in place upon thc su pporting-faec, and providiitgr a leather surface against which the picker-stick strikes.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
