LOOM SHUTTLE-BOX -OPERATING MECHANISM.
SPECIFICATION forming part of Letters Patent No. 352,419, dated November 9, 1886.
Application filed January 30, 1886. Serial No. 190,316. (No model.)
To all whom it may concern:
Be it known that we, WILLIAM LOREY and JOHN BRAUN, both citizens of the United States, residing in the city and county of Philadel' phia, State of Pennsylvania, have invented a new and useful Improvement in Loom Shuttle- Box-Operating Mechanism, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure 1 represents aplan or top view, partly broken away, of a loom having applied thereto an operating mechanism embodying our invention. Fig. 2represents a cross-section thereof in the line as m, Fig. 1, seen from the left-hand side. Fig. 3 represents a rear elevation of a portion of the loom, partly in longitudinal section in the line y y, Fig. 1. Fig. 4 represents a section thereof in the line z a, Fig. 1.
Similar letters of reference indicate corresponding parts in the several figures.
Our invention relates to mechanism for operating or adjusting the shuttle-box in relation to the pickers of a loom; and it consists of the novel features herein described, whereby the regular alternation of the boxes or cells is effected with the greatest facility, and a positive adjustment of the shuttle-boxes is effected without liability of vertical play thereof in the throw of the lay.
Referring to the drawings, A designates the loom-frame, supporting the bearing for a main shaft, B, shafts O and D, and rock-shafts E F. Both shafts O and D are geared with the main shaft B by means of cog-wheels B G D, and
to the driving-shaft G is connected the oscillating lay or batten G by means of the usual cranks, O and pitmen 0 While to the shaft D is connected a reciprocating slide, H, by means of a crank, D and pitman D, the relative angle or positions of the cranks being such that the motions of the lay and the slide are in opposite directions. The rock-shaft E carries the lay G, while the rock-shaft F carries a releasing-lever, F, hereinafter referred to, and is connected with the main shaft by means of arms F and a rod, F to receive motion therefrom. The reciprocating slide H is fitted in guideways A of the loom-frame, to move in a horizontal frame, and upon the slide are two sets of cams or wipers, H H H, for
alternately actuating a lever, J, and thereby operating a reciprocating rod, J, carrying the shuttle-boxes.
On the operating-lever J is mounted ahead, L, having a series of vertical holes or passages, L L L L, which are equal in number to the shuttle-boxes, and in which are fitted two pins or tappets, K K, one to each set of cams, for engaging the latter, the tappets moving or gravitating freely in said holes, which thus constitute guides for the tappets, and also render the latter adjustable in relation to the cams. The cams H, 850., of each set are formed by the vertical edges of spirally-arranged steps or terraces, on which the tappets K K rest in the action of the cams thereon, as hereinafter described, and the top one of which is enlarged to furnish an extended support for the tappets, a space being left between the two sets of steps, at'the converging ends of the cams, of sufficient Width to admit either of the tappets.
Each set of cams or wipers H, 8m, corre-' sponds in shape with the other, and each occupies a reverse position to the other relatively to the line of motion of the cam-supporting slide.
The tappets K K are connected by means of cords K to the outer ends of lifting-levers N, the inner ends or portions of which are in turn connected by means of cords N to the respective arms of the releasinglever F, and to which inner ends of the lifting-levers are hung weights N, so that by the j oint'action of the releasinglever and the Weights the shifting-levers are link, 0, to a loose collar, 0 of a reciprocating sleeve, P, which is fitted on the rook-shaft E, carrying the lay by means of a feather-key, E, so that the sleeve shares the motion of said ICO shaft together with the lay. The collar 0 is fitted into a groove, 1?, in the circumference of the sleeve, and hence .the collar is adapted to shift the sleeve on the lay-shaft without rocking. The reciprocating sleeve 1? is connected by means of a link, P to one arm of an elbow-lever, Q, which has its fulcrum in a pivot, Q, on a bar, Q, of the 1ay-frame,and the other arm of which is connected by means of a link, Q, to the box-supporting rod J, so that a motion of the operatinglever is transmitted to said rod through thesleeve and the elbowlever for adjusting the shuttle-boxes. The bar Q of the lay-frame forms one of the guides for the box-supporting rod J, and the inner end thereof is united'to an arm, Q, on the layshaft.
The pivot O of the operating-lever J is fixed to the loom-frame, and to the upper end thereof is arranged a spring, R, in form of a flat bar, which bears at the free end on a lip or shoulder, R, of the lever-head L, so that by the frictional contact of said spring with the shoulder the operating-lever is steadied in its motion and held against accidental displacement.
For the purposes of explanation, let it be assumed that the lay is in its forward position, the operating-lever J having one of its tappets, as'K, midway between the two sets of cams, and the other, K, in the line of motion of one set thereof, the rearward movement of the slide H, with its cams H, 810., being completed. Now, in the throw of the lay backward the cam'supporting slide H moves forward, as indicated by the arrow'in Fig. 1, the tappet K is released, and the latter drops from step to step of the proper set of cams until said movement of the cam-supporting slide is completed, the operatinglevcrJ in the meantime remaining stationary. Then, when the lay returns to a front position, the camsupporting slide H moves rearward, and the tappet K is displaced by contact with the cam adjacent to the step on which it rests, whereby the operating-lever J is forced in the direction of the arrow shown.in Fig. l, and the box-supporting rod J is forced up to effect a proper adjustment-of another cell of the shuttle-box. \Vhen the cam-supporting slide H has completed its rearward movement, the tappets K K are transposed in relation to the camsthat is tosay, the tappet K is brought into the line of motion of the other set of cams, and is released in the forward movement of the cam-supporting slide, so that when the latter again moves rearward said tappet K is displaced by one of the cams of the proper set,
and the operating-lever is forced in a direction opposite to the arrow for readj usting the shuttleboxes. The coincident cams of the two sets correspond in effect on the operatinglever J, thereby rendering the motion of said lever equal in both directions, and the change of operation and adjustment of the cells of the shuttle-box is effected by the different relative position of the tappets K K as compared in contact with different cams, the result of i which is to produce different adjustments of the shuttle-boxes, so that the order of succession of the shuttle-boxes may be regulated by that means. By the guide-holes L, &c., of the lever-head the tappets K K may be readily adjusted in the desired relation to the cams, inasmuch as it is only necessary to place the tappets in one or the other of the holes.
It will be noticed that the motion imparted to the box-supporting rod J is positive in both directions, and hence a corresponding adjust: ment of the shuttle-boxes is effected, while, owing to the fact that the reciprocating sleeve P may rotate in its actuating collar, the rod. together with its boxes, is not liable to play or move vertically in the throw of the lay, it remaining stationary.
