Specification of Letters Patent.

Patented Apr. 13, 1915.

Original application filed. December 30, 1911, Serial No. 668,784, Divided and this application filed June 12,

To all whom it may concern:

Be it known that 1, ANDREW Wnnuan, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Narrow -Ware Looms, (the same being a division of my application filed December 30, 1911, Serlal No. (S68,78%,) of which the following is a specification.

My invention relates to shuttle operating mechanism for narrow ware looms, the object of my invention being to so construct such mechanism as to lessen the strain upon the parts and prevent injury thereto in case the normal movement of the parts is obstructed from any cause.

In the accompanying drawing Figure 1 is an end view of suiiicient of a narrow ware loom to illustrate my invention; Fig. 2 is a front view of the parts at one end of the loom, and Fig. 3 is a top view of the same.

In the drawings, 1 represents the lay of the loom pivoted at the lower end and having swinging movement imparted to it by means of a crank 3 on the main driving shaft of the loom, the pin of said crank being connected to the lay by a rod 5, and a pin 7, whereby this rod is connected to the lay, being adapted to a grooved slot 8, whereby it may be adjusted nearer to or farther from the fulcrum of the lay and thus regulate to a nicety the beating-up point.

The lay carries a shuttle race 9 which is composed of sections separated by reeds 10 of which there are as many as there are webs to be woven, each shuttle 11 being shot across a reed from one section of the shuttle race to the next and back again. Either the rack and segment, the reciprocating finger or any other available type of shuttle-actuating mechanism may be employed, but I have selected for purposes of illustration the reciprocating finger type.

The head 12 of the lay is grooved for the reception of a bar 13 from which proJect as many properly spaced fingers 14 as there are shuttles to be actuated, the fingers projecting from the bar 13 into position to engage the ends of the shuttles as said bar 13 is reciprocated.

Reciprocating motion is imparted to the bar 13 by means of a crank pin 15 carrying Serial No. 703,288.

an antifriction roller which engages a slotted bracket 16 secured to the bar 13, the crank from which the pin 15 projects being carried by a shaft 17, which is mounted in suitable bearings on the head 12 of the lay and is provided with a drum 18, to which are connected straps 19 and 20, one passing around the drum from left to right and the other from right to left, so that when one strap is pulled downwardly the drum will be moved from right to left and when the other strap is thus pulled the drum will be moved from left to right, rocking movement being thereby imparted to the shaft 17 and to the crank thereon so as to swing the crank pin 15 back and forth, and thereby impart reciprocating movement to the bar 13.

The lower end of each of the straps 19 and 20 is connected to a slide 21, suitably guided in a frame 22, which is pivoted at its lower end concentrically with the lay 1 and is connected at its upper end, by means of a link 23, to a depending bracket 24: on the head of the lay so as to swing with the latter.

Reciprocating movement is imparted to the slides 21 by means of picker levers 25, pivoted at 26 to a suitable support, the forward end of one of these picker levers engaging a slot 27 in one of the slides, and a slot 28 in the frame 22, and the other picker lever engaging similar slots in the other slide 21 and in the frame. When the picker levers are vibrated, therefore, one of the slides 21 will be depressed as the other is lifted and rocking movement will thereby be imparted to the shaft 17 and its crank.

Rocking movement is imparted to the picker levers from a double crank 29, each of the pins of this crank being connected to a bar 30 through the medium of a bar 31 which is guided in a yoke 32 on the bar 30 and carries a yoke 33 guided on said bar, a coiled spring 34 being interposed between the two yokes so that the downward thrust of each crank pin is imparted to its respective bar 30 through the medium of this spring, lift being imparted by means of a collar 35 which is secured to the lower end of the bar 31 below the yoke 32 on the bar 30.

By reason of the use of the springs 34 the picker levers are operated with a yielding pressure, thereby reducing the strain upon thepicker levers, and upon the parts operated thereby, and also reducing the risk of breakage in case the movement of the shuttle, or of the picker bar or other portions of. the picker mechanism, meets with an obstruction.

Each bar 30 is connected to its corresponding picker lever 25 by means of a swinging head 36 pivotally mounted upon a collar 37 secured to the picker lever.

I claim:

'The combination of the shuttle actuating drum, the reversely disposed straps thereon,

slides connected to said straps, picker levers for reciprocating said slides, means for actuating said picker levers, and a frame in Which said slides are guided in their reciprocation, said frame being separate from the lay but pivoted concentrically therewith, and means for actuating said frame so as to vibrate it in unison With the lay.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing Witnesses.

KATE A. BEADLE, HAMILTON D. TURNER.
