To all whom it may concern.-

are attained in the working of the loom, with a simple and compact arrangement of shuttleboxes that reduces the power required to drive it, and enabling us to work the shuttles in .regular continuous rotation or in alternate or reverse order, as desired.

The construction of the improvements is shown inthe following drawings, in the several figures in which the same letters desig-' nate like parts. 1

In the drawings, Figure l is a front eleva tion of theloom. Fig. 2 is a side elevation, (right-hand side.) Fig. 3 is asectional elevation'on .dotted line a0 as, Fig. 4. Fig.4. is a top plan with jacquard, 8m, removed.

In the drawings the parts that are old are omitted,- except so far as they'illustrate the connection of the new parts with the loom.

The details of the devices on the left-hand side of the loom, like those on the right, are omitted.

Our shuttle-boxesconsist of a series of boxes, a, in a sliding frame, a, that rises and falls in a permanent frame affixed to each side of the loom, independentol' the lay, so that either box, as required, can be brought in line with the race on which the shuttle crosses the loom. The boxes a are surmounted by a cylinder, 1), composed of shuttle-boxes arranged around a common center hung in the frame a. This arrangement includes a large number of shuttles in compact form,

2,) hangs.

axis at that end, leaving the innerend next to the lay free and unobstructing the weftthreads by an axis, around which they would be liable to become entangled and soiled.

The sliding frame a is raised and lowered by a cam, c, on the end of shaft 0 (see Fig. 2,) actuating a lever, c ,connected with frame a at its front end by'a rod, d. The cam c is formed to correspond with the number of boxes at which it has to work. The cylinder b'revolves, while frame a is stationary, with thebox of the series a next the cylinder 6 on a levelwith the race, by means of the following devices: A tubular bearing, 0, Fig.4, is aflixed to the frame supporting the jacquard. In this bearing 6 a hollow shaft is fitted, having on its outer end a radial arm, f, projecting forward from which a hook, f (see Fig. On the inner end of the same shaft is a radial arm, fflthat extends backward, the end'of itbeing connected by a rod, 6, with a cross head, h, which is made to slide up and. down by a cam, h, giving a. proper,

pended to it. The inner arm k is connected with cross-head h. by a rod, i, like arm f By this arrangement of parts it will be seen that the hooks f and k are reciprocated up and down in opposite directions at every revolution of the cam h. One of the hooks,f, is united with the top, the other, It, with the bottom, of the vertical arms of the cross l by rods, the cross being pivoted at its center on a stud projecting from a small frame aflixed to the side of the loom. To the horizontal arms of this cross lvertical rods m are attached, surrounded by spiral springs, that hold the cross in position when at rest, at which time the hooks f and 70 play up and down clear of the pins (1 on the shuttle-box cylinder b, there being the same number of pins as boxes. Two horizontal leversm/n, pivoted on the frame at right angles to the cross l, are united to its horizontal arms on each side of the center by links 0. Through eyes in the inner ends of these levers cords p 11 pass, to the lower ends of which weights p are affixed, their upper ends being connected with the jacquard above, in the usual way'of harness-cords, with knots that can be trapped by means of the ordinary needles and patterncylinder governed by the pattern-card, as is well understood by experts. When either of the cords p or p is trapped it raises thecorresponding lever n and turns the cross Z on its axis. This, by its connection with the hooks, thrusts one forward and the other back, bringing the. forward hook into action with one of the pins g on the cylinder above named, and turns it one box:

It will be noticed that the hook k is formed (see detached parts, Fig. 2) to catch the pin 1 on its upward movement. The other, f catches as it descends. The cylinder is thus turned in opposite directions, determined by the hook brought into action. This movement takes place when the frame a and cylinder 1) areat rest.

By the above-described construction and arrangement of parts an accuracy in working the shuttles is insured, with a muchgreater latitude and variety of motion, with less power to work the loom than heretofore, and with great stability and durabilityof the parts.

The improvement of the stop-motion may be described as follows: a is the sliding bar connected with the spring-shipper. This bar slides on the inside of the loom-frame, having two pawls, u M, jointed to the rear end, that are actuated by the stop-cam c. a connects with the thread-stop. It is held up when the weft-thread is running properly. by a finger, w, pivoted to theloom-frame. On this finger a pin projecting from pawl a rests, by which the finger raises it. This pin slides on the finger 20 when the loom is stopped without deranging the parts. The finger w is connected by its hub with another finger, 3 that iscin contact with the grid-lever z, operated by the weft-thread, as well understood by Weavers. The fulcrum to which lever z is atfixed is a rod, 2 extending across the loom in rear of the lay. It bears a similar grid on the other side of the loom. The grids are kept open while the shuttle is passing by means of afinger, t, aflixed to rod z, that rests .on a cam, 25, on the lay-shaft :v. (See Fig. 4.) The other pawl, a is connected with the shuttle-binders by means of a single rod, 1,- extending straight across from the shuttlebinder on one side to that on the other. It turns in fixed supports. A finger, T is affixed to rod 1' opposite each shuttle-binder, and rests against it, so that when the binder is forced back by the shuttle the rod is turned. Just inside the loom-frame, by the pawl a, an arm, "r extends out from rod 7''. This'arm has a slot in it, in which a pin rests, projecting from the pawl 24 by which it is held up-when the shuttle is properly boxed on either side. This device of a single straight rod for connecting the shuttlebinders with the stop-motion is more simple, direct, and perfect than others we are acquainted with.

We are aware that looms have been heretofore made with the shuttle-boxes, both rotatingand sliding, detached from the lay, and placed in a frame on each side of the loom in which they work, or in which is placed revolving boxes mounted in a stationary frame, surmounted by drop-boxes adapted to slide in said frame. We do not claim either of those features, therefore; but

What we do claim is- 1. In combination with a stationary guiding-frame, a sliding frame, a, adapted to work in guides in said stationary frame, and carry-V rying a series of non-rotating boxes,c, surmounted by a series of rotating boxes, I), and mechanism, as described, for raising andloweriug said slide-frame and for turning said rotating boxes, the several parts being constructed and arranged as and for the purposes specified. e 2. The combination, with the rotating cylinder provided with lugs or pins q, of the hooks f k governed by the pattern mechanism and connecting and operating mechanism,

as described, Whereby'the books may be. brought into engagement with andv revolve the cylinder when it is in a state of rest, as and for the purposes specified.
