POSITIVE SH UTTLE-MOTION FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 396,522, dated January 22, 1889.

Application filed July 5, 1888. Serial No 279,060. (No model.)

To all whom it may concern:

Be it known that I, CHESTER F. \VICKWIRE, of Oortland,in the county of Cortland, in the State of New York, have invented new and useful Improvements in Positive Shuttle-Motions for Looms, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the class of shut- 1o tles which are used in weaving wire-cloth, and which are carried alternately on the ends of two arms or bars reciprocating across the 100111 and meeting at the center thereof, where the shuttle is shifted from one of said carrier-arms to the other; and my invention consists in improved, simple, and reliable means for looking the shuttle on one carrier-arm and simultaneously unlocking it from the other carrierarm in the process of shifting the shuttle, as hereinbefore stated, all as hereinafter more fully described, and specifically set forth in the claims.

In the annexed drawings, Figure 1 is a plan view of a shuttle and its carrier-arms em- 2 5 bodying my improvements, and'showing the operation of the same at the time of the meeting of the two carrier-arms. Fig. 2 is an edge view of the same, and Fig. is a plan view showing by full lines the two carrier-arms retreated from each other and the shuttle carried 011 one of said arms and by dottedlines the action of catches and latches in the approach of the two carrier-arms.

Similar letters of reference indicate corresponding parts.

0 0 represent the two carrier-arms, which are reciprocated simultaneously in opposite directions and in line with each other from opposite sides of the loom in any suitable and well-known manner, (not necessary to be here illustrated,) an exemplification of the same being shown in my prior patent of August 4, 1874:, No. 153,693.

A denotes the shuttle, which is provided with shanks it projecting therefrom in diametrically-opposite directions, and adapted to enter the carrier-arms O O, which are made tubular. To the said shuttle, centrally between its shanks, is pivoted a two-armed lever,

Z, in such a manner as to allow said lever to rock in a plane parallel with that of the shuttle. This lever is formed at opposite sides of its pivot with cams b b, and has its arms a a inclined toward the shanks t t and terminating in hooks or catches c c.

To the carrier-arms O O are firmly secured elongated spring plates or latches d d, which project therefrom in such a direction as to cause them to encounter the inclined arms a aof the catch-lever Z in the approach of the carrier-arms to the shuttle.

The aforesaid latches are arranged movably in planes parallel with that of the shuttle, and are of such lengths as to cause them to overlap when the two carrier-arms meet and hold the shuttle tightly between them, as represented in Fig. 1 of the drawings. The latch is provided with the aperture 6 in such relative position as to bring said aperture in coincidence with the catch c, which is directly under it. The free end of each latch is curved slightly outward from the shuttle, as shown at d, in order to allow the approaching end of the other latch to pass under it, and from said end portion rearward for a short distance 7 5 the latch is bowed outward, so as to allow the end of the latch to bear on one cam and stand with the bowed portion clear from the other cam, 19, while one of the. hooks c is entered into the aperture 6 of said latch.

The shuttle is carried by one of the arms 0, the shank t of the shuttle being inserted in the end of said arm, and the latch d of the arm bearing with its free end on the cam 19 on the catch-lever lat the side beyond the fulcrum, and the catch 0 nearest the carrier-arm engaging the aperture e of said latch. In meeting the other carrier-arm O the shank t, which projects from the shuttte toward said arm, enters the latter, and the latch d of this arm first slides with its free end up on the inclined arm a of the catch-lever l, and under the free end of the other latch, and then passes the center or fulcrum of said lever and onto the cam 1) beyond the fulcrum, and in this movement the underlying latch pries the overlying latch away from the catch-leverl and tilts the said lever, so as to throw the catch c out of engagement with the overlying latch,

which has previously confined the shuttle on I00 one of the carrier-arms, and at thesaine time causes the other catch 0 to enter the aperture 6 of the underlying latch.-

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In combination with the shuttle and its carrier-arms, a catch-lever mounted on the shuttle inovably in a plane parallel with the plane of the shuttle, and spring-latches extending from the carrier-arms and movable in the aforesaid plane and adapted to interlock with the catch-lever,substantially as described and shown.

2. In combination with the shuttle and its carrier-arms O O, the two-armed lever Z, pivoted to the shuttle to rock in the plane thereof, and provided with hooks c 0 on its extremities, and the spring-latches (l (7, extendin from the carrier-arms and movable in planes parallel with that of the shuttle and provided with the apertures e 6, adapted to engage the hooks c substan tiall y as described and shown.

at Syracuse, in the county of Onondaga, in

the State of New York, this 3d day of July, 1888.
