STOF-MOTION.

To all @07mm t may concern.'

Be it known that I, KARL SLoAT, a citizen of the United States, and a resident of Scranton, in the county of Laclrawanna and State of Pennsylvania, have invented a new and Improved Stop-Motion, ot which the following is a full, clear, and eXact description.

The object of the invention is to provide a new and improved stop motion designed for use on reeling machines and similar machines, and arranged to quickly and positively stop the reel in case ot' the breaking of a thread or yarn, or the running out ot the yarn from its spool, which requires no line adjustment or sensitive balancing by skilled workmen, and to prevent the parts from beingl actuated by mere vibration incident to the running et the machine.

In order to accomplish the desired result, use is made of a pivoted lifting arm adapted. to liftthe reel out of engagement with the driving gear, pivoted drop arms having eyes 'for the threads or yarns to pass through to normally hold the drop arms in raised inactive position, and actuating' means controlled by the said drop arms and controlling' the said lifting arm to move the latter into active position on the release of adrop arm by this thread or yarn.

A practical embodiment ot the invention is represented in the accompanying drawings forming a part or" this speciication, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a side elevation of the stop motion as applied to a silk reelingmachine; Fig. 2 is a cross section ot' the same on the line 2 2 of Fig. l; Fig. 3 is a similar view of the same with the parts in position after a drop arm is released by its thread or yarn and the reel is stopped from rotating; Fig. 1l; is a sectional plan view ot' the saine on the line 4 4 of Fig. 2; Fig. 5 is a cross section of part of the stop mot-ion and showing more particularly one of the drop arms in dropped position; Fig. 6 is a cross section` of part ot the reeling machine, the section being on the line 6-6 of Fig. l; and Fig. 7 is a front elevation of part of the mechanism for imparting a reciprocating motion to the actua-ting slide.

The reeling machine on which the stop motion is applied is mounted on a suitably constructed frame A in which is journaled a Specification of Letters Patent.

main shait B provided at one end with a pulley B connected by a belt with other machinery for imparting a continuous rotary motion to the said main shaft B. On the main shaft B is secured a driving pulley B2 normally in frictional contact with the peripheral face of a pulley C secured on the shaft D of the reel l) on which the threads or yarns E are Wound, the threads or yarns unwlnding from suitable bobbins or spools E, as plainly indicated in Figs. l and 2.

The reel shaft D is journaled at its ends in open bearings A and A2 held on the ends of the main trame A, thus permitting removal of the hlled reel from the machine and lifting of the pulley C out of driving engagement with the pulley B2 to stop the rotation of the reel D and consequently the Winding up of the yarns or threads E on the said reel in case a thread or yarn is broken or the thread runs out on a spool E', as hereinafter more fully explained.

Each ot' the threads or yarns E passes through an eye F of a drop arm F normally disposed in a vertical position and resting against a rod Gr attached te the traine A and in front of which passes the corresponding thread E (see Fig. 2). The drop arm F is provided with a heel F2 pivoted on a bearing` ll attached to a shaft or rod lil mounted to slide in the direction of its length in bearings A3, AJ* forming parts ot' the main traine A. The shaft H isnor mally held in position, as shown in Fig. l, by the action ot a spring H2 resting at one end against the bearing A3 and abutting at its other end on a pin HP' held on the shaft H. The letthand end of the shaft H normallysupports a starting lever l extending transversely and ulcrumed at I on the main frame A, and the pivotal end ot the starting lever l provided with itorlr inembers I2, I3, ot which the member T3 is provided with an adjusting screw T4, and the fork members straddle the lower end oit a lifting arm J ulcruined at its lower end at J on the main frame A. The upper end J2 of the lifting arm J is in close proximity to the peripheral it'ace of the reel Vpulley C, as plainly indicated in Fig. 2, but when the shaft H is moved to the right and from under the lever I then the latter in swinging downward causes the screw lL to impart a swinging motion to the lifting arm J in the direction of the arrow c so that the top J2 llt) of the said lifting arm J engages the peripheral face of the reel pulley C and lifts the latter and with it the reel so that the pulley C moves out of driving engagement with the pulley B2 (see Fig. 3). VJhen this takes place the reel D comes to a standstill.

In order to move the shaft H to the right against the tension of the spring H2 and with a view to move the left-hand end of its shaft out from under the lever I, the following arrangement is made: rlhe heel F2 of the drop arm F is provided with a rearward extension F3 (see Figs. 2, 3, a and 5) nor mally out of the path of blocks l secured on a slide K arranged parallel to the shaft H and mounted to slide in the direction of its length in the bearings A3, A4 previously mentioned (see Figs. 1 and il).

The slide K `receives a continuous reciprocating motion from the reel shaft D as long as the latter is driven and for this purpose the following arrangement is made: On the slide 1 is secured a collar L (see Figs. l and 6) by the use of a set screw L, and on the collar L is arranged a rearwardly-eXtending pin L2 engaging a forli N forming part of the lower end of a lever N fulcruined at N2 on the main frame A.. The upper end of the lever N is provided with a fork N3 engaging a crank arm O held on the hub O of a gear wheel O2 journaled in suitable bearings arranged on the main frame A. The gear Wheel O2 is in mesh with a pinion P having a hub P journaled in suitable bearings on the main frame A, and on the hub P is secured a crank arm P2 engaging a cross head Q formed on or attached to a traverse bar Q, mounted to slide in suitable hearings arranged on the main frame A. The traverse bar Q, is provided with eyes Q2 through which pass the threads or yarns E after passing through the eyes F so that the threads E are properly fed onto the reel D in the usual manner. The pinion P is provided with a bevel gear wheel R (see Figs. 1 and 6) in mesh with a bevel gear wheel R secured on a shaft R2 journaled in suitable bearings arranged on the main frame A, and on the said shaft R2 is secured a gear wheel R3 in mesh with a pinion R4 secured on the reel shaft D. Now when the reel shaft D is rotated as previously explained, then a rotary motion is transmitted by the pinion R4 and gear Wheel to the shaft R2 which by the gear wheels R, R, P and O2 rotates the crank arm O so that a swinging motion is given to the lever N which by its fork N and the pin L2 imparts a sliding motion to the slide K.

From the foregoing it will be seen that as long as the reel shaft D is rotated a sliding motion is given to the slide K and in case one of the drop arms F is released by its thread or yarn E and swings downward into the position shown in Fig. 5 then the extension F3 of this drop arm F passes into the path of the adjacent block K of the reciprocating slide K whereby the block K imparts a sliding movement to the extension F3 and consequently to the bearing H and the shaft or rod H to lift the latter from the left to the right in the direction of the arrow b thus moving the left-hand end of the rod or shaft H out from under the starting lever I. Then this takes place the latter swings downward and thereby imparts a swinging motion to the lifting arm .l so that the latter raises the pulley C o-ut of engagement with the pulley B2 and consequently further rotation of the reel D ceases. It will be not-iced that when rotation of the reel D ceases the reciprocating motion of the slide K ceases owing to the fact that the slide is actuated from the shaft D by the mechanism above described.

1n order to prevent the rod or shaft H from turning in its bearings, it is provided with a depending arm H4 having a fork H5 straddling a tension rod S, and in order to prevent the slide K from turning an arm K2 depends from the slide and is provided with a fork K2 straddling a tension rod S. The tension rods S and S are attached to the main frame A and the threads or yarns E pass around the said tension rods prior to passing to the eyes F of the drop arms F, as will be readily understood by reference to Fig. 2.

1t is understood that in case any one of the threads or yarns E breaks or the thread runs out from the corresponding spool E then the corresponding drop arm F swings downward and in doing so its extension F3 moves into the path of the adjacent block l( of theslide K. As the slide K reciprocates continually it imparts motion to the extension F2 of the drop arm F whereby the shaft H is moved to the right and out from under the starting lever I. The latter now swings downward and imparts a swinging motion to the lifting arm J in the direction of the arrow a to lift the pulley C out of engagement with the pulley B2 and consequently further rotation of the reel D ceases. When the broken thread has been mended and replaced in the eye F of the returned drop arm F then the operator swings the starting lever I upward so that the member 12 of the said lever imparts a rearward swinging motion to the lifting arm J to cause the latter to lower the pulley C until this pulley is again in frictional contact with the peripheral face of the continually rotating pulley B2. A rotary motion is now again given to the reel D and the slide K is reciprocated.

It is understood that when the drop arm F is swung back into vertical position and the lever I is raised the left-hand end of the shaft H again moves under the lever 1 by the action of the spring H2 so as to support the starting lever I in its normal position.

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