STOP-MOTION FOR TWISTERS, SLC.

SPECIFICATION forming part of Letters Patent No. 342,990, dated June 1, 1886.

Application filed September 6, 1884. Serial No. 142,368. (No model.)

To all whom it may concern:

Be it known that I, CHARLES F. ALEXAN- DER, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Stop-Motions for Twisters, Spoolers, Thread-Vinders, Ste., which improvement is fully set forth in the following specication and accompanying drawings, in ro Which- Figure 1 represents a vertical section in line a' zr, Fig. 2, ot' a twisting-machine having applied thereto a stop-motion embodying my invention. Fig. 2 represents a top or plan view of the machine shown in Fig. l, partly broken away. Fig. 3 represents a view of a portion detached from the left side of Fig. l. Fig. 4 represents a detached View of a holder for a bobbin-spool, Src., as embodied in my invention. Fig. 5 represents a horizontal section of a portion in line y y, Fig. l.

Similar letters of reference indicate corrcspending parts in the several figures.

My invention consists of a stop-motion for a twister, spooler, thread-Winder, Snc., the

same' embodying a balanced holder for a bobn bin, spool, quill, &c., and mechanism operated thereby for operating the shipper or stopping device of the machine, and other details of construction, as will be hereinafter fully set forth.

Referring to the drawings, A represents the frame ofthe twisting-machine, and A represents a beam or cross-bar at the top thereof,

on which is mounted the balanced holder B for a bobbin, spool, quill, &c., the same consisting of. a suitable spindle or pin, which is provided with knife-edges or journals C, which project from the spindle below the bobbin,

4.o Src., and rest upon bearings D, which are secured to the beam A of the machine.'

Supported on a proper part of the frameA below the holder is a sliding frame, E, which has at top a rotary bar, E', from which rise arms F, so located in proximity to the lower ends of the spindles of the holders that when the latter are in their normal positions during the operation of the machine they arms F of the frame E pass said spindles without contact therewith, as shown by the full lines, 5o

Fig. 1.

The rod E', which is horizontally arranged, has its bearings in bosses or 'eyes a in the upper part of the frame E, and one end of said rod has connected with it a toe, G, which pro- 5 5 jects toward a vertically-moving stopping-bar,

H, the same being guided in a proper part,

' A", of the frame A of the machine, and having a shoulder, G', which is adapted to engage with said part, said toe being so disposed in 6o relation to thc bar H that when the rod E is rotated by coming in contact with the holder B the toe is advanced against the bar H, and, owing to its partial rotary motion, releases said bar, so that the latter is permitted to rise, 6 5 as will be hereinafter explained.

J represents a spindle, which is mounted on the frame A and receives motion from a drum or pulley, b, and a belt or band, c, the latter passing around a cone or whirl, d, on said spindle. The upper end of the bar H is beneath the top roller, K, of a set of rollers, K K2 K, between which the thread or yarn passes in this case from the holder B to the spindle J, the lower rollers, K K2, being properly mounted on the frame of the machine and receiving motion from the driving-shaft by means of the gear-wheels R and R2.

Connected with the upper end of the bar H is an upwardly-projecting arm, G, which, with the bar, forms a fork, said arm being arranged between t-he back roller of the set of rollers K and the guide G, adjacent to the holder B.

On the base of the cone or whirl d of the spindle J is a lug, J', and on the. bar H is a finger, H', the latter being adjacent to said lug, so that when vthe baris raised the finger strikes the lug and interlocks therewith.

On the bar H is a pulley, L, having a horizontal axis, the same being grooved and serving to guide the belt, band, or cord c. In order to prevent displacement of said belt there is connected with the bar H a guard, M, somewhat of the form of a hook, the same overhanging the periphery of the pulley.

l In order to raise the bar H when its shoulder G is released from the part A of the frame A, there is pivoted to the same and a suitable bearing on the frame A a weighted lever, N, the normal position of the bar and connected parts being shown in Fig. 1.

Depending from the beam Aare hangers I, which have slots e in the lower portions,

, through which the lower ends of the spindles or pins of the holders B project, said spindles or pins being provided with the `journals or knife-edges C, which are hung freely on the bearings D, secured to the beam A, as has been stated, and readily secu in Fig. l.

The rod E carries a weight, E", the tendency of which is to prevent improper rotation of said rod, and when therodis rotated to return it to its normal position, holding the toe G from the bar I-I.

In order to cause the belt or band c to enter its groove h in the cone or whirl d when said belt is being lowered by the bar II, the said cone or whirl is formed with a spiral groove, k, which extends from the upper part of the cone to said groove h, so that as the bar H is lowered the belt or band engages with said spiral and is thus directed to the groove h. The frame E receives reciprocating motion in one direction by means of a cam, Q, which is connected with a pulley, Q', the latter being mounted on a shaft, R, and receiving power from any proper part of the machine, the said cam engaging with an arm, S, which projects laterally from the frame E, and receives mot-ion in one direction from said cam, the motion being communicated to the frame. The opposite motion is accomplished by means of weights T, attached to cords T, which pass around pulleys V on the frame A, said cords being connected with the frame E. In lieu of the cords T and weights T springs may be used, as shown in the dotted lines in Fig. 2.

The operation is `as follows: The holder B is held against one. of the walls of the slot e, and thus clear of the path of motion of the arm or lug F, of the rod E', by the tension of the yarn or thread. Should the latter break the holder is free to vibrate, which it does by the action of gravity, and it swings against the opposite wall of the slot e, and is in the path oi' the arm or lug F, whereby the latter strikes the holder and causes the rod E to partially rotate, and as the toe G releases the shoulder G of the bar I-I from the part A of the frame, the bar is raised by the weighted lever N lifting the top roller, K, of the set of rollers K K K2, and also the yarn from the back roller, K2, of the lower roller, thereby preventing the passage or feeding of the yarn or thread. Simultaneously therewith the pulley L, which rises with the bar H, forces the band or belt c upward from the base of the cone or whirl d to the narrow part thereof,

whereby the band or belt is slackened, the` yarn or thread is tied or united, the created tension of the same again draws the holder B to its normal position, clearing it of the path ofthe lng F, and the rod E by the action of its weightE is also restored to its normal condition, disengaging the toe G from the bar H. The bar II is drawn down by its foot or handle H", with which said bar is provided, so that the shoulder G engages with the frame A, and the band c is restored to its groove h in the cone or whirl d, and the lug J and finger H are disconnected, the spindle J then again rotating and the yarn receiving its tension. The upper roller, K, of the set of rollers K K KIl is also lowered, and thus permitted to rotate by contact with the lower rollers, so as to feed the yarn or thread to the spindle.

'The rod E is shown diagonal in order to have a toe at each end for operation on opposite sides of the machine ior purposes of duplication of work, in which case the beam A also extends diagonally, and the holders B are disposed in like order on said beam.

Subject-matter described in this speciication and 'shown inthe accompanying drawings relating to the construction of the balanced holder is not claimed herein, such boing described, illustrated, and claimed in an application foran improvement in bobbin-holders filed September (i, 1884, and bearing Serial N o. 142,367.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
