BATTEN- -OPERATING MECHANISM FOR LOOlVlS.

SPECIFICATION forming part of Letters Patent No. 744,843, dated November 24, 1903. I

Application filed May 15, 1903. Serial No. 167,266. (No model.)

To all whom it may concern;

Be it known that 1, CHARLES W. WIDER- STROM, a citizen of the United States, residing at Georgetown, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Batten- Operating Mechanism for Looms, of which the following is a specification.

This invention relates to improvements in to a mechanism for operating the batten or lay of looms used for weaving wire fabric; and it consists in certain peculiarities of the construction, novel arrangement, and operation of the various parts thereof, as will be here inafter more fully set forth and specifically claimed. In weaving fine-mesh wire fabric or cloth with the machines or looms heretofore in common use great difficulty has been experienced, and, in fact, it has been almost impossible to turn out a grade of cloth which is smooth, even,-and without imperfections, by reason of the fact that when one of the weft or filling wires is beaten up by the batten and the same is retracted to allow the shuttle to pass and carry another weft-wire the former weft-wire will at times slip back part way, so that when the next weft-wire is beaten up they come too close together. This slipping causes stretch 0 of the warp, and after a time the warp-wires will break, thus making imperfections in the cloth and also rendering it rough and uneven. If a pick or two of the filling or weft wires are removed from the cloth, this leaves the 55 warp-wires exposed and tender, and the cloth will often tear across.

The principal object of the invention is to provide a mechanism which shall operate the batten in such a manner as to'cause it to act 40 intermittently, or, in other words, to cause it to dwell or stop for awhile in its place after each of the weft-wires is beaten up, and also to dwell on its rearward stroke sufficiently to allow the shed or warp to close up and open again for the next pick before the shuttle crosses, thus insuring a high-grade, perfect, smooth, and even product.

In order to enable others skilled in the art to which my invention pertains to make and use the same, I will now proceed to describe it, referring to the accompanying drawings, in which Figure 1 is a view in side elevationof a batten-operating mechanism embodying my invention, showing by broken lines the position the parts will assume when the weft-wire is beaten up. Fig. 2 is a plan view thereof with a portion of the tension-spring broken away. Fig. 3 is a front view of the batten. Fig. 4 is an edge view of the spring-actuated 6o lever, showing it detached. Fig. 5 is a rear end view of the reciprocating pitman.

Like numerals of reference refer to corresponding parts throughout the difierent views of the drawings.

The reference-numeral 10 represents the batten, which may be of the ordinary or any approved pattern or construction and mounted on the loom in the usual manner. At each end of the batten is mounted on a suit- 7c able bracket 11, secured thereto, the front end of a reciprocating pitman 12, which is preferably formed with four parallel rails or members 13, located a slight distance apart, as shown in Figs. 1, 2, and 5 of the drawings. The rear ends of said rails or members are connected together by means of a plate 14, secured thereon by means of bolts 15 or otherwise. Suitably journaled on the loom is a driving-shaft 16, which extends between the upper and lower rails of the pitman 12, as is clearly shown in Fig. 1 of the drawings. Rigidly mounted on the shaft 16 and located thereon between the side rails of the pitman 12 is an eccentric cam 17, which has that portion of its periphery located the greatest distance from the shaft 16 formed concentric with the axis of said shaft-that is, the portion of the periphery between the points indicated by the numerals 18 and 19 is concentric, While the remaining portion thereof is eccentric, to the axis of said shaft. Transversely journaled on the pitman 12 near the juncture of its rails or members 13 is a shaft 20, on which is mounted a roller or 5 sheave 21 to impinge the periphery of the cam. Secured to the rails 13 of the pitman 12 near their rear ends is a bracket 22, which extends downwardly and has pivotally secured thereto at its lower end a spring-actu- 10o ated lever 23, which is preferably bent at about its middle toward the cam and is provided with an opening 24 in said bent portion, in which opening is rotatably mounted a roller or sheave 25, which also impinges the periphery of the cam. The upper end of the lever 23 is connected to the upper portion of the batten by means of a spring 26, so that the rollers or sheaves 25 will be kept in continuous contact with the periphery of the cam. Mounted between the members 13 of the pitman 12, so as to slide thereon, is a stop-box 28, which may be adjusted by means of a screw 29, which passes through the bracket 22, and which box is used to strike against the shaft 16 as the pitman 12 slides thereon in its forward movement, thus insuring even meshes.

From the foregoing and by reference to the drawings it will be seen and readily understood that as the cam rotates from the position shown by continuous lines in Fig. 1 the pitman 12 will be moved forward to the beating-up point, as indicated by dotted lines in said figure, at which point the reeds 27 will be caused, by reason of the concentric portion of the cam, to dwell or remain at a deadrest, allowing time for the shed or warp to close up and open again for the next pick before the shuttle crosses. When the cam shall have rotated farther, so that the concentric portion is out of contact with the roller 21, the tension of the spring 26 will retract the batten, as is apparent. As the cam further rotates it is evident that when the concentric portion thereof contacts with the roller 25 the batten will again be caused to dwell or stop, thus allowing time for the shuttle to cross.

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

1. The combination with the batten, of a driving-shaft journaled near the same, a cam mounted thereon and having a portion concentric with the axis of said shaft, a pitman connected at one of'its ends to the batten and movably supported near the cam, a roller journaled on the pitman to impinge the cam, and means to hold the roller in continuous contact with the cam, substantially as described.

2. The combination with the batten, of a driving-shaft journaled near the same, acam mounted on the shaft and having a portion concentric with its axis, a pitman connected at one of its ends to the batten and movably supported near the cam, a roller journaled on the pitman on one side of the shaft, another roller movably journaled on the other side thereof, both of said rollers adapted to impinge the cam, substantially as described.

3. The combination with the batten, of a driving-shaftjournaled near the same, a cam mounted on the shaft and having a portion concentric with its axis, a pitman connected at one of its ends to the batten and movably supported near the cam, a roller journaled on the pitman on one side of the shaft, a lever pivotally secured on the other side of the shaft, a roller journaled on said lever, and a spring connecting the upper end of the lever to the batten so as to hold the two rollers in continuous contact with the cam, substantially as described.

4. The combination with the batten, of a driving-shaft journaled near the same, a cam mounted on the shaft and having a portion concentric with its axis, a pitman connected at one of its ends to the batten and movably supported near the cam, a roller journaled on the pitman on one side of the shaft, another roller movably journaled on the other side thereof, and means to hold the rollers in continuous contact with the cam, substantially as described.

5. The combination with the batten, of a driving-shaft journaled near the same, a cam mounted on the shaft and having a portion of its periphery concentric with the axis of the shaft, a pitman having parallel rails embracing the shaft and connected at one of its ends to the batten, a roller journaled on the pitman on one side of the shaft, another roller movably jonrnaled on the other side thereof, and-means to hold the rollers in continuous contact with the periphery of the cam, substantially as described.

6. The combination with the batten, of a driving-shaft journaled near the same, a cam mounted on the shaft and having a portion of its periphery concentric with the axis of the shaft, a pitman having parallel rails embracing the shaft and cam and connected at one of its ends to the batten, a roller journaled on the pitman between the rails thereof near their juncture, a lever extending be tween the side rails of the pitman and pivotally secured at its lower end, a roller journaled on said lever, and a spring connecting the upper end of the lever and batten, substantially as described.
