LUCIUS DIMOCK, OF HEBRON, AND IRA DIMOCK, OF MANSFIELD, CONNECTICUT.
MACHINERY EORy TREBLING SINGLE THREADS.
`Speccaton of Letters Patent No. 14,858, dated May 13, 1856.
To all whom t may concern:
Be it known that we, LUoIUs DiMocK, of Hebron, in the county of Tolland and State of Connecticut, and IRA DiMooii, ofMansfield, in the county of Tolland and State of Connecticut, have invented certain new and useful Improvements in Machinery for Trebling Single Threads; and we do hereby declare that the following is a full, clear, and exact description of thesame, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l, is a longitudinal vertical section of a trebling machine constructed according to our invention. Fig. 2, is a plan of the same. Figs. 3 and 4 are detached views of portions of the machine, which are only indistinctly shown in Figs. l and 2. Figs. 5 and 6 are diagrams of the enchaining devices, illustrating the operation of the machine.
Similar letters of reference indicate corresponding parts in the several figures.
In the machinery which constitutes the subject of this invention t-he trebling is effected as in some other machinery for the same purpose, by forming a series of loops in a single thread and enchaining the said loops.
This invention consists in certain improvements for effecting the above operation without any manual aid and saving` much ofthe delay which is usually necessary to effect the unhitching of the loops.
To enable others skilled in the art to make and `use our invention we will proceed to describe its construction and operation.
A, A, is the frame of the machine which ma be of any desired length and width. Near the front end of this frame are situated any desired number of bobbins B, B, containing the strand threads and immediately infront, a corresponding number of spools C, C, for receiving the trebled threads. The said bobbinsB, B, are placed on stationary vertical spindles b, ZJ. The spools C, C, have their journals c, c, arranged. in vertical guides a, a, above two large friction driving rollers D, D, which are secured on a shaft E, and are held down in contact with the said friction rollers by springs c, c, attached to hooks f, f, which take hold of their liournals. A little behind the bobbins B, B, is situated a transverse rockshaft Gr, which is furnished with a number of hollow curved arms g, g, which we will call, conducting arms, corresponding with the number of spools B, B, and also furnished with a weighted arm z', to counterbalance the arms g, g, and behind this rockshaft is a traveling carriage F, carrying another rockshaft H, which is furnished with a number of bent arms z, 71., which we will call hitching arms, corresponding with the number of spools B, B, and arms g, g, each of the said arms h., 7L., carrying a hitch pin L, which is fitted wit-h an external loose tube or roller. The carriage F, .is attached to endless chains or belts I, I, which run on pulleys J, and K, which are secured on two shafts J and K one of which is near the front and the other at the eXtreme rear of the machine. The carriage receives a motion back and forth by a rotary motion given to the shaft J', said motion being reversed by suitable means, not necessary to be shown, as the carriage arrives out or home.
The rockshaft G, has attached to one end, a plate j, whose form is best shown in the detached View, Fig. 8, being that of a circle with an angular notch fr, m, and it has on its inner face, a stud j, which is operated upon to throw the arms g, g, in a backward direction by means of a long straight arm la, attached to the carriage F. .This arm also carries a stud Z, to operate on the notched part of the plate y'. The rockshaft H, has firmly secured to it, near one end, a segment shaped plate m, the form of which is best shown in Fig. et, which carries two studs s, s', between which a limited movement is allowed to a short lever n, which is fitted loosely to the end of the shaft, the said lever serving to give, at a proper time, a rocking movement to the shaft H,by coming in contact with a stationary pin y), on the side of the framing. The rockshaft H, has attached to it, a spring e, which tends to throw the pin s, which protrudes on both sides of the segment plate m, into contact with the standard F of the carriage, and thus keeps the shaft H stationary at all times, except when the lever n, is not `in contact with the pin 29.
The shaft J, has fitted to it a loose pulley Q, and a fast ratchet wheel r, the said pulley being furnished with a spring pawl which engages with the ratchet wheel, only when the shaft is revolving in a direction to draw forward the carriage F, toward the front of the machine. This pulley is connected by a belt 2f, with a pulley P, on the shaft E, and consequently motion is communicated to the said shaft and the friction rollers D, D, and by them to the spools C, C, when the carriage runs forward but not when it runs back.
Betweenthe bobbins B, B, and spools C, C, a sliding traverse bar L, carrying thread guides u, u, is arranged for the purpose of guiding the trebled thread on the spools C, C. The traverse motion of this bar is produced by a cam M, and a spring o, the said cam heilig placed loosely on astud secured in the side of the framing and driven by a belt/w, from a small pulley y, on the end of the shaft E. Behind the traverse bar there are stationary guide pins 0, 0, to keep the trebled thread clear of the bobbins B, B.
The mode of operation is as follows: Before starting, the carriage F is run up near to the shaft Gr, and the thread from each bobbin is connected to the shaft G, through the hollow conducting arm g, which is opposite the bobbin and from thence around the hitch pin p', then led forward for some distance, then back again around the conducting arm g, and forward again, as is shown in Fig. 5, which is a plan view of the enchaining mechanism. This, it will be seen, leaves three thicknesses of thread, 1, 2, 3, in front of the arms g, g, and these are to be made secured to the spool C, corresponding to the bobbin B, after which the carriage is allowed to run back. During the running back of the carriage, the portions of thread, l, 2, 3, remain stationary, but thel hitch pin L, draws of the thread from the bobbn B, and runs out with a double thread, the conducting arm g, being all this time caused to incline backward by the tension of the thread passing through it. When the carriage has been run all the way out, the motion of the bands I, I, is reversed to run it in again, then the spool C, receives a motion from the roller D, which causes it to take up the portions of thread l, 2, 3, and the tension of the parts 2, 3,
which form a loop on the conducting armV g, soon causes the said arm to incline forward until it arrives at such a position that the thread will no longer remain on it, but slips off, as is shown in the side view, Fig. 6, and, catching the thread passing through the said arm, enchains it and draws it forward. During the whole of the remainder,
of the forward movement of the carriage (a very small portion comparatively, up to this point having been accomplished) the doubled thread which was carried out by the backward movement of the carriage, is, with the addition of a third portion of thread, which continues to be drawn from the bobbin B, through the conducting arm g, making in all a trebled thread, wound up on the spool O. As the carriage arrives within a very short distance of the shaft G, the inclined end of the arm 7c, strikes the stud y, in the plate j, on the last named shaft, as shown in Fig. 3, and causes the said shaft to move far enough to throw back the conducting arm g, till it has about the degree of backward inclination, shown in Fig. 1, by which Atime the stud y, arrives on the hori- Zontal top edge of the arm 7c, and the continued movement of the carriage no longer, for the present, affects the shaft G, but when this position of the conducting arm g, has been attained, the hitch pin being now very near the end of the said arm, the lever n, which up to this time, has been freelyresting againstrthe pin s, in the segment plate m, as shown in Fig. 4, strikes the pin 27, and the continued movement of the carriage with the lever in contact with the pin p, causes the shaft H, to turn a little way, in such a direction that the hitching arm L, descends, as shown in Fig. l, far enough to throw the loop which is on its hitch pin, over the end of the conducting arm, as illustrated in Figs. 1 and 2, and the portion of thread 1, 4L, forming the loop on the hitch pin, strikes the conducting arm, and is thereby caused to slip over the top of the hitch pin, whose loose external sleeve or roller is coned at the top to facilitate this operation. The loop having slipped off the hitch pin passes down to the bottom of the conducting arm, and the hitch pin having now arrived under the space between the curve of the conducting arm and that portion of the thread issuing from the said arm, is caused suddenly to fly up by the escape of the lever n, past the pin p, and consequent action of the spring z, and thereby to hitch on it, the portion of thread issuing from the conducting arm, so that when the directions of the rotation of the shaft J, and of the motion of the chains or belts 1,1, are changed, the hitch pins runs back with that portion of the thread doubled and thus commences a repetition of the looping and enchaining operation. The last described port-ion of the operation, viz the hitching of the thread on the hitch pin, is assistedV by the action of the pin Z, in the arm s, on the side of the notch in the plate j, which causes the conducting arm g, to descendalittle farther simultaneously with the swinging up of the hitching arm and hitch pin. When the carriage runs back, thelever n, passes the pin j), without moving the shaft H, owing to the play that is allowed for it between the pins s, s. It should be observed that the conducting arms and hitching arms must be curved as shown in Fig. 2 in order to pass each other.
It will be understood from the foregoing description Vthat the machine is entirely selfacting. It needs no attention except to change the empty bobbins for full ones and the full spools for empty ones.
What We claim as our invention and desire to secure by Letters Patent, is,
l. The rockshaft G, with a hollow conducting arm, g, operating substantially as described to conduct each strand thread from its bobbin to the hitching pin or its equivalent and to effect the enehaining of the loops.
2. The attachment of the hitehing pin or pins L, to the arm or arms h, of a rockshaft, which is operated substantially as described, for the purpose of forming and disengaging the loops.
3. The arrangement and combination of the rockshaft G, having a hollow conducting arm or arms g; the traveling carriage F, carrying the rockshaft G, and its Vibrating hitching arms 71,; the strand bobbins B, B, and the trebled thread spools C, C, the Whole operating substantially as herein set
