Specification of Letters latent.

Application filed February 14, 1913. Serial No. 748,289.

To all whom it may concern:

Be it known that I, SAMUEL B. Crrrrme, a citizen of the-United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Looms, of which the following is as ecification.

My invention relates to ooms and particularly to the provision of means to facilitate the operation of taking a lease in looms equipped with a stop motion.

The invention will be understood by reference to the accompanying drawings in which- Figure 1 is a diagrammatic view of a portion of a loom showing the use of my invention therein; Fig. 2, an enlarged end view of a portion of Fig. 1 showing my invention applied to the back warps, a part of the construction being broken away; Fig. 3, a side view of Fig. 2 with the drops omitted; Fig. 4 a view similar to Fig. 3 with the compound terminal in its raised position; Fig. 5 a view showing the application of my inven- Fig. 6, a front view of Fig. 5; and Fig. 7 a detail of the means for coupling the terminal clamping supports.

Similar reference numerals indicate similar parts in the several views.

Referring to the drawings the numeral 1 designates the lay, 2 the harness, 3 the back warps. and 4 the pile warps of a double pile fabric loom. Such loom will be equipped with a stop motion of any of the usual forms. such motion including drop devices 5 on the back warp and similar or equivalent drops on the pile warps. In my application, Serial No. 733.571, filed November 26, 1912, I have described a stop motion for the pile warps in which the drops are supported upon an inclined section of the warps. In Figs. 1, 5 and 6 of the present case I have shown substantially the same arrangement wherein the drops are carried on a section of the pile warps passing between the warp supporting rods 6, these rods being held in end pieces 7. The compound terminal which is embraced by the drops, consisting of a circuit terminal bar 8 and a terminal blade 9 set into but insulated from the bar 8, is slidably supported in slots 10 in the end pieces 7. Rings 11, or other retaining means, are passed through openings 12 in the bar 8 and engage pins 13 fixed in the end pieces 7. Darin the normal running of the loom, the termmal is in the position indicated by full lines in Figs. 5 and 6. In such position there is not sufficient room between the warp supporting rods 6 and the terminal to permit the taking of a lease at the end of the warp, and it is for this purpose that I provide the slots 10 whereby, when a lease is to be taken, the terminal may be raised to the top of the slots, the rings 11 being disengaged from pins 13 and hung upon pins 13'. as shown by dotted lines in Figs. 5 and 6. \Vhen the terminal is thus raised the operator takes out the casing rods 31, then raises one set of pile harnesses and lowers the other set, and this leaves the threads crossed in the space between the harness and the terminal. Lease rods are then inserted, one on each side of the crossing and moved near to the terminal supporting frame. The rods spread the warp through the frame and when so spread a rod is placed between the warps at the left of the frame and the one nearer the frame at the right removed. The remaining rod at the right is then moved toward the frame, thus spreading the second part of the lease through the frame, and another rod inserted at the left of the frame and the red at the right thereof removed. The operator then passes the lower back warps in the same way when the lease rods 14 will be in the position shown in Fig. 1. The new pile warp beam 15 is then conveniently placed at the back of the loom, with the lease rods 16 inserted. as shown in Fig. 1, and, the operator breaks a thread from the end of the warp in the loom and one from the new warp and twists them together between the lease rods 14 and 16. hen all of the ends are thus twisted. if it is desired to run without a lease, the operator takes out both sets of rods 1 1 and 16. The warp beam is then placed in proper position on the loom, the casing rods 31 replaced. the terminal lowered to normal position, the loom then being ready for operation. If desired to run with a lease, only one of the sets of rods 14 or 16 is removed.

While the above description applies to the pile warps, the invention is equally adapted to the back warps, as shown in Figs. 2. 3 and 4. In such adaptation of my invention the drops 5 are supported upon a section of the war between the rods 17 supported in brac ets 18 adjustably secured to the U- shaped end pieces 19 by bolts 20. Each of the end pieces 19 has an n ward extension 21 against which the terminal supports 22 and 9.3 are adapted to be clamped. As shown in the drawings, the terminals bear against the sides of the supports and the latter are normally seated upon the end pieces 19. The extension 21 comprises two legs, as shown in Figs. 3 and 4, and, through the space 24 between the legs, bolts 25 are passed, the said bolts also assing through slots 26 in the terminals, an having nuts 27 which, when tightened up, clamp the terminals in position against the sides of their supports and against the extension 21, and also through the two outer terminals clamp the supports 22 and 23 a ainst the extension 21. As shown in Fig. T, one of the clamp supports, as 22, is provided with a laterallyextending head .29, and the other clamp supportis provided with a correspondingly shaped socket to receive the head 29. This interlocking means prevents the clamp supports .22 and 23 from spreading when the nut 27 is loosened.

When it is desired to take a lease on the back warps. the nuts 27 are loosened and the supports 22 and .23 with the teminals, raised, and the terminals are then clamped in their raised position as shown in Fig. 4. In the loom shown there is always a lease rod at .28 and when the new lease is to be taken said rod is moved close to the terminal supporting frame thus spreading the warps through the frame. A lease rod is then placed between the spread wraps at the left of the frame and rod 28 removed. Then a. rod 32 is placed at the right of the crossing of the warps on the right hand side of the frame and moved close to the frame thus spreading the second part of the lease through the frame. A second rod 33 is then placed between the spread warps at the left of the frame. The new warps are then tied in and the lease run back and rod 28 placed as in normal running.

In a plain loom where there is no lease rod between the harness and the terminal, a lease is taken by raising alternate harnesses, drawn back and passed through the terminal frame as above described.

The above-described feature of an adjustable terminal is of particular advantage in a double pile fabric loom, such as illustrated,

and also where the warp is inclined to roll or to become matted together, or when crossed, as it sometimes is, by improper handling when it is better to run without the lease rods. \Vhen the loom is run without lease rods, then it is necessary to make a new lease at the end of the warp and to do so it is necessary to make the terminal adjustable to give the necessary space through which the lease rods may be )assed.

\Vhen the terminals are raised the dctcctors or drops remain in their normal position as they are held in such position by the warp threads. The terminals are merely moved to the top of the opening in the drop devices and then clamped in the raised position.

\Vhat I claim and desire to secure by Letters Patent of the United States is 1. A loom having a stop motion comprising drop devices carried by the warps, a circuit terminal with which the drop devices co-act, a frame in which said terminal is supported, lease rods so located with relation to the supporting frame as to pass a least through the support, and means for adjusting said terminal in its support when tlu lease is taken.

2. A loom having a stop motion eompris ing drop devices carried by the warps, a eir cult terminal with which said drop devices co act, a frame in which said terminal is sup ported, lease rods so located with relatioi to the supporting frame as to pass a leas through the support below said tcrminaf and means for raising said terminal in it support when the lease is taken.

3. A loom having a stop motion compris ing drop devices carried by the warps, circuit terminal extending transversely r the loom and with which said drop devim co-act. a frame in which said terminal supported, said frame having guide bai over which the warps are passed, lease rm so located with relation to the supportin frame as to pass a lease through the supper and means for moving said terminal awe from said guide bars to provide a spa through which a lease may be passed.

In testimony whereof I have hereun signed my name in the presence of two su scribing witnesses.
