WEFT-REPLENISHING MECHANISM FOR LOOIVIS.

SPECIFICATION forming part of Letters Patent No. 767,425, dated August 16, 1904.

Application filed February 3, 1903. Serial No. 141,781. (No model.)

T0 [t7] 1071 0772 it may concern/.-

Be it known that I, FELIX ODONNELL, a resident of the city of Pawtucket,in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in IVeft-Replenishing Mechanism for Looms; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to looms for weaving, more particularly to that class of looms which are provided with mechanism for automatically replenishing the shuttle with either cops or bobbins or for replacing or exchanging shuttles containing full cops for those containing empty ones.

The object of the invention is to increase the capacity of the loom by providing means whereby the shuttle will positively come to a full stop or rest in a certain position for a definite period, so as to make possible and practical the replenishing of the weft-thread in the shuttle when the loom is running at a high velocity. It'is fully described in this specification and illustrated in the accompanying drawings.

Figure 1 is a side elevation of a loom with automatic replenishing mechanism on the right end and a shuttle-box separate from the lay and fixed to the loom-frame. Fig. 2 is an enlarged detail view of the fixed shuttlebox. Fig. 3 is a perspective view of the mechanism which operates the swell on the fixed shuttle-box and illustrates its connection with the swell-operating mechanism which moves with the reciprocating lay, a portion of said lay being dotted in position. Fig. I shows a plan view of the lay at its extreme backward position and in line with the fixed shuttle-box. Fig. 5 shows a plan view of the lay in its forward position, with the shuttle remaining at rest in the fixed box in position to receive a full cop.

In the construction, A Aare the end frames of the loom, and G is the arch, on which may be supported a filling or replenishing mechanism of any particular construction; but I pre- 5 for to show that described and illustrated in my patent of March 18, 1902, No. 695,696. On one end of the arch is rotatably mounted the cop-holding wheel D, on the periphery of which are a series of spring cop holders. This wheel is actuated in the manner and by the mechanism more particularly described in my patent above referred to.

B is the lay, at one end of which is the fixed shuttle-box E, which box is separated from said lay and held in position on the loom: frame in a line with thelay when it is approximately at the end of its backward stroke. (See Fig. 4-) The other box, R, is attached to the other end of the lay B. The shuttle b is 55 thrown back and forth across the loom in the usual way by action of the picker-sticks e and f through the rotating cam-shaft F and the cams (Z and (Z. The picker-stick f oscillates with the lay B in the usual way, while the 7 picker-stick a simply reciprocates in the fixed shuttle-box E.

0 is the full cop, which is to be struck down into the shuttle by the automatic filling mechanisms above mentioned when it is time for replenishing said shuttle.

In the connection between the fixed and the moving shuttle-boxes is a finger Gr, fixed on a short shaft The upper end of said finger engages the swell E on the stationary shuttlebox. On the inner end of this short shaft g, which is journaled in the frame, is fixed a lever H, the outer end of which is pressed upward by the action of the spiral spring 7L, coiled around the rod 6 and supported by the 8 5 bracket I, through which rod e' works. Resting on the inner end of this lever H is the lever J,- which is fixed to the end of shaft j, which shaft is held in hearings on and moves with the lay. Shaft j is held in hearings on 9 and extends along the back side of the lay B.

K is the ordinary dagger, mounted on shaft 1' andnormally held down by the spring 70 in position to engage the frog Z (which is connected in the usual way to the starting-lever and brake, not shown) when the latter moves forward, providing the shuttle is not in either of the boxes.

L is the ordinary swell-aetuating which in this rase is mounted on to the end of shalt j and ens ees tl 1 i in i 1e swell it i pper end j connected to and operated hy t thrown in a position to cooper with tha; on the lay and raise the dagger, threiwh t l lever J and shal t j, so it will not en; frog Z as the lay again moves forward,

When the shuttle enters the lined swell is opened and the (he; and held out of engagement through the linger levers and shaft], and when the shuttle is in th ing box the dagger I; is raised and h by the linger L. at which time the tion of the mechanism on the lire C.

In a loom the combination of a stationary shuttle-box independent of the moving lay and held in a fixed position on the loom, a shuttle-box on the opposite end of the reciprocating lay, a swell on each of the shuttleboxes, and means located on the lay to move with it and operatively connected to the swell on its said shuttle-box, separate means located on the stationary shuttle-box and operatively connected with the swell in said box, and arranged to operate in conjunction with said moving means to raise the dog and prevent the stopping of the lay when the shuttle has entered the said stationary box, substantially as described.

6. In a loom, in combination, a stationary shuttle-box, a shuttle-box to move with the lay, a swell on each of said boxes, a swell-operating finger and a dog operatively mounted to reciprocate on the lay, and a finger operatively mounted to act on the stationary box, each finger arranged to operate independent of the other, except at the time the shuttle is being thrown across the lay, at which time each independent mechanism is in the proper position to cooperate with the other.

In testimony whereof I have hereunto set my hand this 26th day of January,A. D. 1903.

FELIX ODONNELL.
