UNITED STATES PATENT OFFICE.
CHRISTOPHER DUOKIVORTH, OF THOMPSONVILLE, CONNECTICUT.
SHUTTLE-BOX MOTION IN LOOMS.
Specification forming part of Letters Patent No. 9,815, dated June 28, 1853; Reissuecl July 4:, 1865, Nos. 2,018 and 2,019.
To all whom it may concern:
Be it known that I, CHRISTOPHER DUCK- woRTH, of Thompsonville, in the county of Hartford and State of Connecticut, have invented a new and useful Improvement in Power-Looms for Weaving Figured Fabrics; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, which make a part of this specification, in which Figure 1 is a perspective view of the shuttle boxes and the levers, &c., which work them. Fig. 2, is a perspective view of a section showing the form and position of the friction rollers and notched slides, which together work and guide the lever G, which moves the shuttle boxes, and the gearing by which the changes are produced, and the two pawls by which it is worked. Fig. 3, is a view of one of the friction rollers, showing one of the forms. Fig. 4, is a view of another form. Fig. 5, is a plan of the end of a shuttle box for four shuttles. The dotted lines show the direction of the three mo tions, vertical, diagonal, and horizontal, in which the shuttle boxes will move.
My improvement consists in the manner of operating the shuttle boxes by means of the levers, friction rollers, notched slides, &c., so that the shuttle boxes may receive a lateral, vertical, and diagonal motion, at pleasure, and may also be kept in any one position as long as is required for any figure or character of the fabric, and be changed backward and forward at pleasure, beinggoverned by. the card pattern.
I make the frame A, &c., the breast beam B, B, the lathe C, and the picker staves D and D, in any of the common and well known ways used in power looms. I make the shuttle boxes F and E of parts or with partitions, so as to contain four or more shuttles, as seen at a, and so arrange them that each box may be moved vertically, laterally, or diagonally, when necessary, to bring the required shuttle to the position to be acted on by the picker staff, which connects with it by a rod, Z), working in the hollow cylinders c and 0. These shuttle boxes, G and F, are supported on upright bars, d and cl, which are acted upon by means of pins in the extremes of the rocking lever, G G G", as seen near d, and d,
Fig. 1. This lever, G, G, G, is secured in the center to the swinging bar, H, which swinging bar is supported in a free bearing at the upper end, (attached to the race beam of the lathe,) while its lower end is movable in a slot, 6, and is pressed toward the left by the spiral spring, f, so as to cause the lever, G, &c., to bear in the center of the notches in the slides, h, &c., and rest on the friction rollers (ii and j j, Fig. 2) contained in the circular case, I, Figs. 1 and 2. This case, I, is revolved, when necessary, by the bevel gear wheel, K, Figs. 1 and 2, and pinion, 9, Fig. 2, (indicated by dots at g, Fig. 1,) they being worked by the dogs or pawls, L and L, Figs. 1 and 2, and the ratchet wheels, R and S, Fig. 2, by the vibratory motion of the lathe, C, to which the case, I, wheel K, pinion g, and ratchet wheels R and S, are attached. The two pawls L and L, may for some purposes be worked by a cam, as shown at t, Figs. 1 and 2, which will raise the pawl, L, off of the ratchet wheel R, which by means of the spiral spring, 71., Figs. 1 and 2, will raise the pawl L, up against the ratchet wheel S, so as to revolve the case, I, the contrary way, but in most, if not all, cases the cam, t, must be removed and the pawls governed wholly by the card pattern. This I case contains four friction rollers, (i, z', j, j, Fig. 2,) the forms of which are particularly shown in Figs. 3 and 4, and is furnished with four notched slides, as seen at h, h, h, h, Fig. ,2, the centers of which notches guide the lever, G, &c., (laterally,) as it rests in them. These notched slides, h, &c., are moved from side to side in the case, I, by means of two levers, M and N, Fig. 1 (when either of the levers are depressed) by the effect of the inclined planes of these levers, (one of which is seen at N, Fig. 2,) coming in contact with the inclined planes on the ends of these slides, shown at h, &c., Figs. 1 and 2. The slides have sufficient end chase to carry the lever, G, &c., from one side to the other of the central prominence on the friction rollers, and thereby cause it to give the lateral motion to the shuttle boxes as the levers, M and N, are alternately depressed. The levers M and N work on joint pins at the left hand end, one of which is shown at is, Fig. 1, and are connected by a short transverse lever, Z, rocking on a fulcrum, we, so that when one is depressed the other will be elevated. The lever, N, Figs. 1 and 2, is elevated by the force of the spiral spring, n, n, the upper end of which is attached to the under side of the race beam of the lathe, C, and the lower end to the lever, N, as seen in Fig. 2, and it is depressed by the action of the cam, 0, Fig. 1, on the lever, P, P, by means of the connecting rod Q, Figs. 1 and 2, and by the operation of the transverse rocking lever, Z, Fig. 1. When the lever N, is elevated the lever, M, is depressed, and vice versa, so far as the cam, O, is concerned in the operation, while working alone. This cam, 0, may be shifted or adjusted to any desired position, so as to operate the levers, N and. M, as required, to the extent to which a cam can be used, but at most times the operation of the levers, M and N, must be governed by the card pattern, and in many cases the cam must be removed and the operation of the levers governed wholly by the card pattern, (as will be readily understood by all who are acquainted with weaving figured fabrics or with building looms for that purpose,) the operation of the lever, Z, being to prevent both levers (M and N) from being depressed at the same time, while the operation governed by the card pattern may be to hold up either of the levers for any length of time (or any number of shoots of the shuttles) or to hold them both up if need be.
On the same arbor or shaft with the wheel K, Figs. 1 and 2, I place tworatchet wheels, R and S, Fig. 2, for the purpose of revolving the wheel, K, either way by means of the vibratory motion of the lathe, C, and the stationary pawls or dogs, L and L, acting (one or the other) on the appropriate wheel, as represented by L and R and L and S. Either of these pawls may be raised or depressed off of the ratchet wheel when not needed by any of the common methods used in looms to direct the form of the figure to be woven, though they must be governed by the card pattern.
The power for working the lathe, C, may be applied in any of the usual ways, so as to revolve the shaft of the wheel, T. At each end of this shaft is a crank, or crankpin, each of which works a connecting rod, one of which is shown at 0, Fig. 1, (the other being concealed,) which communicate a vibratory motion to the lathe, C, and the wheel, T, by gearing with the large toothed wheel, U, revolves the shaft which carries the cam, O, which depresses the lever, P, P, Fig. 1. 'When the power is applied, the wheel, T, revolves, and by means of the connecting rods, 0, the lathe, C, receives a vibratory motion for beating up the woof or filling. This vibratory motion of the lathe, C, causes the ratchet wheels, R and S, to recede from the stud, V, Fig. 2, to
which the pawls, L and L, are fastened, which causes the ratchet wheel It to be revolved by the pawl L, in the direction in dicated by the dart on that wheel and to carry wit-h it, in the same direction, the wheel, K, which, by means of the pinion, g, revolves the case, 1, Figs. 1 and 2, over toward the right by a repeated motion, and when the other pawl, L, is used the motion of the lathe causes the ratchet wheels S, to revolve in the direction indicated by the dart on the wheel, S, and carries with it the wheel, K, which, by means of the pinion, g, revolves the case, I, over toward the left by a repeated motion, so as to bring the several notched slides, h, &c., and friction rollers 2', 2', j, 7', alternately under the lever, G, &c., to guide it and to rock it, soas alternately to depress and elevate the shuttle boxes, E and F, at each end or to give them a vertical motion. At the same time the wheel, T, gearing with the wheel, U, will revolve the cam, 0, (when that cam is used,)
the larger side of which will depress the lever, P, P, and, by means of the connecting rod, Q, depress the lever, N, so that its inclined plane (seen at N, Fig. 2) will come in contact with the inclined plane on one of the notched slides and force it outward, so as to guide the lever, G, &c., outside of the prominence on the center of the friction rollers, and thus give the lateral motion to the shuttle boxes, carrying the box, IE, back, and bringing the box, F, forward, as represented in Fig. 1. When the smaller side of the cam, O, is downward, the spiral spring, a, n, Fig. 1, and n, Fig. 2, will raise the lever, N, above the ends of the slides, h, &.c., and by the operation of the transverse lever, Z, Fig. 1, the lever, M, will be depressed by its own weight, (unless sustained by the governing effect of the card pattern,) so that its inclined plane will come in contact with the outer ends of the notched slides, h, &c., and force them back, and thereby guide the lever, G, &c., to the back side of the central prominence on the friction rollers and cause it to carry the shuttle box F, back and bring, E, forward, and thus give a lateral motion to the shuttle boxes opposite to that before described, and when the change in the slide (to give the lateral motion) coincides with a change in the friction rollers (as from i to j, Fig. 2, or vice versa,) to give the vertical, the lateral and vertical motions being combined, will produce the diagonal motion, as from corner to corner of the shuttle boxes, as indicated by the dotted line from i to j, &c., Fig. 5, and thus the slides, 71,, &c., and rollers 'Z, i, and j, j, (when the pawls L, and L, and the levers, M and N, are governed by the card pattern) will cause the lever, G, &c., to produce every change in the relative positions of the shuttle boxes required to produce the desired figure, as the case, I, may remain at rest during any number of throws of either of the shuttles, and it may be revolved forward or backward as one or the other of the pawls (L or L) and the ratchet wheels (R or S) are used, and when the pawl L, and the ratchet Wheel, S, are used, the inclined plane, 2), Fig. 2, will operate the notched slides, h, &c. The card patterns will be connected with the pawls, L and L, and the levers, M and N, by any of the well known means now in use for similar purposes, according to the construction of the loom.
The picker staves, D and D, may be Worked in any of the well known ways, as by a band or strap, attached at p and p, and carried over the pulleys, g and 9, Fig. 1, and worked by a treadle or any other convenient way.
The loom may be stopped, when the shut tles are not thrown home into the boxes, by the lip or projection, 1", Fig. 1 (which is thrown up by a spring in the usual way) coming in contact with the breast beam, B, B, and when the shuttle is thrown home into the boxes the inclined planes, 5 and s, acting on the bent ends of the protecting rod, 2?, will press the lip, 1", down so that it will pass under the breast beam, B, B, and allow the lathe to work freely.
What I claim as my invention, and desire to secure by Letters Patent, is
1 The method of giving a three-fold movement, (lateral, vertical, and diagonal,) to the shuttle boxes, (E and F,) as described, by which I am able to operate any required shuttle at any given pick.
2. I also claim the apparatus for operating the shuttle boxes, consisting of the case I, (with its friction rollers z', i, j, j, and slides, h, 72, h, ]L,) combined with the levers, (M and N,) which work the slides, and the principal lever, (G, G, G,) which moves the shuttle boxes, when the whole is constructed, arranged, and combined, substantially as herein described.
