By this construction it is possible to adjust the rods longitudinally of the block.

In order to fasten the members to the plate 24 I provide the lower member with an upstanding extension and the upper member with a depending extension 36, each of these extensions being provided with slots 37 through which passes a bolt 38 the head of which is seated in plate 24.. By means of nut 39 on the screw 38 the

members

26 and 27 are securely fastened to the plate 24 and by reason of the slots 37 it is possible to vary the distance between the

rods

28 and 29. Screw 40 is threaded in the upper member 27 and is placed to engage the extension 35, thereby permitting close adjustment of the rods. Slots 4.1 formed in the plate 24; receive ribs 41 formed on the block members to hold them against angular motion.

Referring particularly to Figs. 2 and 3 it will be seen that each rod is provided with a socket 42 having formed therein a slot 43. so proportioned as to receive the tongues 41- of the shuttles. Pivoted to each rod is a lever 45 having a hook &6 which extends into the socket and across the slot 423 and is held yieldingly in such position by spring 47 secured to the rod. A controller arm 48 is pivotally mounted to each rod and has a cam portion 49 which is positioned to engage tripping devices (not shown) to release the shuttle at the proper time. The rods, sockets, and hooked and releasing levers are substantially the same as shown in the aforesaid patent and may be operated as indicated therein.

An important feature of my invention is the means by which the inner ends of the rods are coupled together so as to form mutual supports for each other to more e'liiciently support the shuttles. To acconr plish this result I have provided a bolt 50 which extends between the rods and is threaded therein as closely to the sockets 42 as the selvage of the cloth will permit. The bolt is held in place by nuts 51 and may be adjusted so that the outer ends of the rods are the same distance apart as the ends received by the block 21.

The operation of the loom is the same as set forth in Patent #1,26S,098, the upper shuttle being on one side of the loom and the lower shuttle on the opposite side. As the blocks 21 move inwardly the advancing tongues of the shuttles enter the approaching socket of the opposite rod and by means or the cam faces on the releasing levers tl e shuttle is released from the rod which moved it to mid position and is connected to the opposite rod which operates to finish the motion of the shuttle through the shed. It will be seen by the arrangement set forth that the bolts 50 tie the rods of each pair together so that the shuttles are given additional support and are presented to their respective sheds without objectionable sagging. T his result is attained without interfering with the locking and releasing levers. The rods are mounted for endwise adjustment relative to the blocks 2l. to accommodate various widths of fabrics and lengths of shuttles, but it will be seen that with such variations the rods 50 and the levers carried thereby will always be the same distance from the shuttle irrespective of the distance between the shuttle and the blocks 21.

Having thus described my invention it will be evident that changes and modifications may be made therein by those skilled in the art without departing from the spirit and scope of the invention as set forth in the claims and I do not wish to be otherwise limited to the details herein disclosed, but what I claim is:

1. In a double shuttle motion for looms, a pair of shuttle supporting rods, shuttle receiving and releasing devices on each of said rods, means to move said rods together toward and from weaving position, a shuttle supported on one 01? said rods, and means passing from one of said rods to the other of said rods to cause both rods to support said shuttle.

2. In a double shuttle motion for looms, a reciprocating block, a pair of rods carried thereby, shuttle receiving and releasing devices on each of said rods, a shuttle attached to one only of said devices, and means spaced from said block to connect the ends of the rods adjacent the shuttle whereby each rod assists in supporting said shuttle.

3. In a double shuttle motion for looms, a reciprocating block, a pair of rods longitudinally adjustable in said block, shuttle receiving and releasing means on each of said rods, a shuttle carried by one only or" said rods, and means adjacent the shuttle to connect said rods together to cause each rod to support the shuttle.

4. In a double shuttle motion for looms, a block reciprocatingly mounted on the loom, rods carried by said block adjustable in the direction in which the block slides and also transversely of said direction, shuttle receiving and releasing means on each rod, a shuttle received by one only of said receiving and releasing means, and means connecting the ends or the rods together to cause both rods to support the shuttle and permit adjusment of said rods tranversely of the direction in which said block moves.

5. In a double shuttle motion for looms, a reciprocating block, a pair of spacedrods carried thereby, shuttle receiving and re leasing means carried by each rod, a shuttle carried by but one of said receiving and releasing means, and a connector extending between the ends of the rods adjacent the shuttle to tie said rods together and cause each to assist in supporting the Weight of the shuttle.

(5. In a double shuttle motion for looms, a. reciprocating block, a pair of rods carried by said block, shuttle receiving and releasing means carried by each rod, a shuttle carried by but one of said receiving and releasing means, and connections between the ends of the rods adjacent the shuttle to connect said rods together and to cause each to assist in supporting said shuttle, portions of the receiving and releasing means being located between the block and said connections.

7. In a double shuttle loom, a shuttle motion on each side of the loom comprising a pair of spaced rods, a shuttle attached to each pair of rods and connections between the rods of each pair to transfer part of the Weight of the shuttle from the shuttle sup porting rod of one pair to the other rod of the same pair.

In testimony whereof I have hereunto afiixed my signature.

WILLIAM M. VVATTIE.
