Shuttle-Box Motion 910,132,157, Patented 00t.15,1872.

IMPROVEMENT IN sHurTLEBoxMoT|oNs.
Specification forming part of Letters Patent No. 132,157, dated October 15, 1872.
.To all whom it may concern:
Be it known that I, BARTON H. JENKs, of Bridesburg, in the county of Philadelphia and State of Pennsylvania, have invented a new and Improved Box-Motion for Looms; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing making part of this specification, in which n p Figure 1, Plate 1, is an elevation of one side of a loom-frame having the box-movement applied to it Fig. 2, Plate 1, is a top view of the same parts; and Fig. 3, Plate 2, is a front view.
Similar letters of reference indicate corresponding parts in the several figures.
This invention relates to an improved mechanism for operating shuttle-boxes of looms for weaving fancy fabrics, when -such boxes, on either side of the loom, are arranged aroundla common center and brought into proper positionby a forward or backward rotary motion.
In carrying out my invention I employ a studded pattern drum or chain, which receives intermittentrotary motions from the main drivin g-shaft through the medium of a cam, a pawllever, and pawl. I also employ a pair of vertically-movin g stepped plates, the rods of which are connected to arms which radiate from a shaft carrying on one end a toothed sector, which latter engages with a pinion on one end of the shaft of the shuttle-box drum 5 and in combination therewith I also employ au angular vertically and laterally vibrating depressing-lever, which is pivoted to a lever that is acted on by a cam on the main driving-shaft.
n One arm of the depressing-lever plays over the steps of the stepped plates and atcertain times depresses one or the other of these p1at-es,while the other arm receives the flattened end of an angular lever which is acted on by the studs of an extension, a, shown in Fig. 3. S represents a spring for holding the drum C by friction, and c represents a pinion spur-Wheel, which is keyed on the outer end of the drumsha-ft b, and which engages with the teeth of a vibrating segment, c. This segment c is keyed on the outer end of a shaft, f, which is arranged beneath the extension a, and which carries on its inner end two arms, f', of equal length. To the extremities of arms f are attached the upper diverging end of rods g g, which extend downward, become parallel to each other, and terminate in flat plates g1 g1, the upper edges of which are stepped, as shown in Fig. 3. The steps of the plates g1 incline in opposite directions, and the plates them selves descend loosely through a slot made through a bracket, g2. This bracket g2 is fast on the lay-beam pivot so as to vibrate therewith. It will be seen that, by alternately depressing the stepped plates g1 g1, the box-drum C will receive an oscillating motion about its axis, and that, by depressing either one of said plates g1 more or less, any one of the shuttleboxes e may be brought into line with the raceway W. This is effected automatically by the following mechanism: D represents a patterndrum, (it may be a patternchain,) which is provided on its periphery with studs p, varying in length and distance apart, according to the figure t0 be woven. D is a ratchet-face on one side ofthe drum D, the teeth of which are engaged by a pawl, E, which is pivoted to the long arm ot'avertically-vibratin g lever, F, having its fulcrum on a stud, t', projecting from frame A. The shorter arm of this leverF lies beneath a single throw-cam, G, on a drivingshaft, G this cam raises the pawl E once every revolution of shaft G and moves the patterndrum D a distance equal to the length of one ratchet-tooth, D. It represents an angular lever, which is pivoted at j to frame A. The uppermost arm of this lever lies upon the pattern-drum D, and is raised by the studs p. The lower flattened end s of lever R is received loosely in a notch in the short arm t of an angular lever, t, the longest armof which extends over the steppedA surfaces of the plates g1 g1, and receives intermittent lateral movements from the lever R, the length ot' which movements vary according to the distance the studs p extend from the periphery of pattern-drum D. The lever t is used to depress the stepped plates g1 g1, and to the accomplishment of this object it is pivoted to a short outwardly-projecting arm, n, of alever, N, which has its fulcrum on stud z' and lies over a single throweam, J, on shaft G. When the lever t is moved over the proper step of one or the other plates g1, the-cam J depresses this lever t, and it, depressing the stepped plate, moves the required shuttle-box into position for throwing a shuttlc. P is an angular lever, one arm of which is connected by a rod, r, to lever F, the other arm of which rises on one side of the shuttle box drum, and is for the purpose of pushing the picker beyond the outer end of this drum with certainty, so that the drum will revolve when desired, and not be liable to break or derange the parts.
Having described my invention,what I claim as new, and desire to secure by Letters Patent, is-
1. In combination with the lifting stepped rods g g, the lever N, its arm t having a lateral and vertical vibration, the lever lt operated by the pattern-cylinder and moving;` the arm t, the combination being and operating as
