STOP-MOTION FOR SPOOLERS, &0.
SPECIPICATION forming part of Letters Patent No. 330,906, dated November 24:. 1885.
Application filed January 2, 1885. Serial No. 151,'770. (No model.)
To all whom it may concern:
Be it known that I, JOHN LANCASTER, of Dover, county of Strafford, and State of New Hampshire, have invented an Improvement in Stop-Motons for Spoolers, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.
This improvement in stop-motions for spoolers or winders for woolen, cotton, or worsted yarns has for its object to ship the belt upon the loose pulley of the winder, and at the same time operate two brakes, they being both applied upon the breaking of a thread or the running out of a thread end, one brake being applied to the drum and the other to the roller, whereby the winding mechanism is stopped instantly, and the broken end of the thread is prevented from being carried around the spool. Kinking of -the yarn is also pre vented. Heretofore, so far as my knowledge extends, upon the breaking or running out of a thread, the winder continued to run after the belt was thrown off, and did not stop until the drum had eXpended its momentum, so that the broken ends of the threads were rolled around the spool, thereby making the threads on said spool of uncertain length. By the application of my improved stop -motion the winder or spool is stopped upon the breaking of a thread, and before the end can be once wound around the spool, thus obviating the necessity for the operator to turn the spool back to find the lost end, and enabling the production of a spool containing threads of more uniform length, which is of great advantage when dressing the war-ps for the loom; and, further, the warp-dresser operator is enabled to run the spool down to within a few rounds of the spindle. J
My improved stop-motion is so constructed and applied to the winding-machine as to readily enable the operator to instantly stop the same, to effect the change from empty to full bobbins, for which reason all the yarn can be run off the bobbin before stopping.
My invention consists, first, of a sheath and reciprocating rod, the former provided with a depending bifurcat-ed arm, and a series of hooks adapted to permit the passageof thread therethrough and to engage the rackbar upon the breaking of a thread, combined with a shipper-rod, its lever, and a disk provided with a pin to engage the bifurcated arm of the sheath, and a latch held in engagement With the shipping-lever and adapted to be disengaged therefrom upon a partial rotation of the disk.
The invention further consists of a shipper, a shipper-rod, and shipper-operating mechan ism, said shipper-rod having a lateral movement, and being provided with a collar, combined with a pivoted quadrant adapted to be moved on its pivot by the collar on the shipper-rod, and having connected therewith a friction-brake applied to the drum-shaft.
The invention further consists of a friction- 'mechanism applied. Figs. 2 and 3 are details of the latch-Operating disk; Fig. 4, a detail of the latch which is operated to release the shipper-operatng lever; Fig. 5, a detail show ing the latch and shipper-operating lever in plan view. Fig. 6 showsin side elevation the spooler with applied stop mechanism. Fig. 7 is a sectional detail of part of the spooler,with the hooks shown in plan view and their arrangement with the rack and sheath; Fig. 8, a detail to more clearly illustrate the arrangement of the hooks, the normal position of the said hooks in the operation of the machine being shown in dotted lines, the position thereof upon the breaking of athread being shown in full lines; and Fig. 9, a detail of the brake which is applied to a pulley on the drum shaft, together with accompanying mechansm.
The spooler or winder-frame A, the drum B on shaft b, the spool B fast and loose pulleys b' b shipper b shipper-rod bf, and rollers c and n' are and may be of any usual construction. The drum-shaft b, by its pulley d,
belt d', pulley e, crank-pin e', connecting-arm e and angle-lever 6 operates the rack D, causing the latter to have a reciprocating movement on the anti-friction rollers f, se-

cured in the braeketsf',attached to the top of the frame A. The sheath F is attached to the rod g, mounted in the brackets f', 'and is adapted to move on one set of the anti-friction passes over the rack D and through slits in' the sheath F, the said hooks being held above the rack in the position shown in dotted lines by the threads which engage the outer .ends thereof, so that upon the breaking of a thread or the running out of a thread end, the hook previously uphcld thereby falls into the position shown in full lines and engages the teeth of the rack, whereby the sheath is reciprocated or moved in unison with the rack. A slotted bracket, g& connected with the frame, receives a disk, G, provided at its ,front side with two pins, 2 3, which, at their under side, rest on the top of the said bracket, the disk near its periphery having at its opposite ends a third pin, f The pins 2 3 have attached to them latch-lifting cords or wires 4 4, attached to a latch, g When the rack and sheath are reciprocated, as before stated, the bifurcated arm f .connected with the sheath, by its engagementwith the pin f of the disk G causes the said disk to be turned or moved in one or the other direction, and by the hook-lifting connections to lift the latch g out of engagement with the shipper-lever H. Upon the shipper-lever being released by the withdrawal of the latch therefron, the coiled. spring 5, fastened to the longer arm of said lever and to the pivot 6 of the quadrant J, immediately pulls the shipper-lever toward the quadrant into the position shown in Fig. 5, so that the latter, slotted at 9 to engage the pin 7 'of a collar, 8, on the shipper-rod b moves the said rod laterally, and with it the shipper b thus transferring the belt from the fast pulley b' to the loose pulley b. The shipper-rod b* is provided with a second collar, K, having a rounded edge, k, which in the normal position of said rod, when the belt is on the fast pulley b', is arranged about over the center of the concave face of the quadrant J, so that when the shipper-rod is moved laterally in its hearing by the operation of the lever H, the rounded edge of the said collar is moved along in contact with the concave surface of the quadrant from the center toward one end thereof, thereby partially turning said quadrant on its aXis 6. A friction-strap, m, or brake attached at one end by a pin, m', to a part of the frame A, (see Fig. 9,)is passed thence over a pulley, m on the drum-shaft b, and is then attached to the quadrant near one end by means of the screw-rod m entering the projection m the rod having its slack taken up by nuts, as shown in Fig. 9.' A second thin friction-strap, n, (see Fig. 9,) passed over the roller n' at a little distance from its end, is attached to the shorter arm of a lever, n which is pivoted to the frame at n, and has its free end kept in engagement, by means of a suitable spring, s, with the end of the quadrant J, opposite that having the projection m The movement of the shipper-rod b* in the direction of the arrow, Fig. 1, carries with it the collar K, which, by its action on the right-hand end of the quadrant, turns the same, as described, causing the depression of that end of said quadrant, whereby the friction-strap m is drawn closely about the pulley m so as to prevent the further rotation of the drum B, and at the same time the uplifting ofthe opposite end of the quadrant raises the end of the lever n against the action of the spring s, and insures the application of the brake n to the roller n' to stop the rotation of the said roller. Hence it will be seen that upon the breaking of a thread, or the running off of an end from a spool or cop, and the consequent dropping of a hook, h', and its engagement with the rack D, the belt is transferred from the fast to the loose pulley on the drum-shaft b, and brakes are applied to said dr'um-shaft, and also to the roller-shaft, to instantly stop the drum and roller, and enable the operator to adjust the thread or threads before the end can wind once around the spool. The shipperrod b* has a collar, 19, provided with a backwardly-extended pin, 20, which enters a suitable slot in an upright lever, 21, pivoted at 22 on the framework, the lower end of the said lever being joined to a lever, 23, suitably held on the floor, so that the 'operator by the foot may drive the lever 21 and slidethe shipper-rod.
