WonoEsTER, Massa- STOP-IVIOTION FOR LOOIVIS- SPECIFICATION formingpart of Letters Patent No. 777,089, dated December 13, 1904:. Application filed January 15, 1904. Serial No. 189,037- (No model.)

To all whom it may concern:

Be it known that I, GEORGE GoonLINE, a citizen of the United States, residing atPhiladelphia, county of Philadelphia, State ofPennsylvania, have invented an Improvement in Stop-Motions for Looms, of which the follow- 1 ing description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts. Thisinvention has for its object toimprove and simplify the construction of stop-motion means employed in looms, especially stop-motion means made operative on the failure of the shuttle to be properly boxed, as it will be understood that if the loom is not instantly stopped the portion of the shuttle projecting outwardly from the box will as the lay is moved forward smash out the warps. I have also shown provision for releasing the shipper-lever whenever for any reason the weft fails to be laid in a shed; but such feature is not herein claimed.

As I have herein chosen to illustrate my invention the crank-shaft has applied to it a friction-clutch, one member of which is represented as a loose pulley and the other as a disk; but I may employ any usual frictionsurfaces. Ihave provided means between the shipper-handle and the lever controlling the position of the loose friction-pulley with relation to the fast friction-disk whereby the degree of pressure of said friction-faces when in use may be determined accurately and made more or less. I have also improved the construction of the brake that coacts with the brake-pulley on the crank or other shaft when the loom is to be stopped and have provided means whereby the brake may be readily thrown off by hand whenever the operator desires to turn the loom over by hand.

Figure 1 in perspective shows a suiiicient portion of one end of a loom with my improvements added to enable my invention to be understood. Fig. 2 is an end view of the parts of the loom shown in Fig. 1. Fig. 3 is a detail showing some of the parts of Fig. 2, but in a different position. Fig. iis asection taken inside the loom-frame to show the dagger, the binder, and binderfinger; andFig. 41*

shows the part of the loom-frame with the square hole therein containing the square part of the bolt (5. Fig. 5 is a view showingthe parts of the loom below the breast-beam and the race of the lay.

A represents the end frame of the loom, A the crank-shaft; A Fig. 4, partof the usual eonnecting-rod intermediate said crank-shaft and the lay A, which latter is pivoted in usual manner. (Not herein shown.) The crank-shaft has fastened to it a toothed gear A, that engages a larger gear A on and rotates the cam-shaft A The crank-shaft has fast upon it at one side of the gear A a brake-pulley A and at its opposite side the fast member 13 of a fric tion or clutch pulley, the other member, B, being loose on the crank-shaft, said members having smooth faces ,which are forced in contact, as will be described, when the crankshaft A is to be rotated.

A hub E ofthe loose member B of the friction-clutch abuts a collar B slidably mounted on the crank-shaft A. so that when said collar is moved to the left, Fig. 1, the loosemember-B will be made to engage the fast member B and rotate the crank-shaft, thus driving theloom. The loose memberhas an opening leading into an oil-chamber forming part of said member, such construction being common and not herein claimed.

The collar 13 has extended from it one or more studs B", that are embraced by a straplike portion of a lever B, mounted to turn about a stud B, sustained by an upright B erected from the floor ata short distance from the loom end.

- The lever B has a stud a, that receives an eye at one end of a two-part adjustable connection, shown as a rod a, threaded, and. thereby made adjustable in a screw-threaded rod-head (i that is connected by a stud o with one arm a" of a rock-shaft (6, having suitable bearings a to sustain journals at the ends of said rock-shaft, said rock-shaft having connected with it at one end the shipperlever a which is made of spring steel and so bent that the front side of the rod acts with a considerable friction against the edge 2 of the slot 3 in the shipper-guide plate A, in

which said shipper is movable. This shipper, owing to its springy quality, acts always in all positions of the shipper against a lever b, pivoted at Z) and provided with a right-angled portion 6 b the portion 5 standing always in and partially filling the shipper-holding notch 5, while the longer part b of the right-angled portion is extended downwardly below the shipper-guide plate and has a shoulder 6. (See Fig. 1.)

A short arm 6*, extended from the rockshaft to which is secured the shipper-lever, has connected with it a strong spiral spring 6 attached at its upper end to a screwrod 5, extended through a guideway 6 and provided with a nut 72 the adjustment of which on the screw-rod changes the effective tension of the spring If, so that said spring will act with greater or less celerity in moving the shipper-lever from the shipper-holding notch 5 into its outward position, Fig. 1,

which is of advantage in many ways in a quickoperating loom.

That the friction between the loose and stationary clutch members of the clutch may be controlled exactly according to the requirements of the work and to provide for wear an eye at one end of the rod to may he slipped off the stud a after Withdrawing the cotterpin 10, and the rod may be turned in one or the other direction and be then reapplied to the stud and the cotter-pin inserted.

Fig. 1 shows a weft-fork-carrying slide 0, supposed to be mounted in usual guides on the breast-beam and constructed when the filling is absent to be moved outwardly in any usual manner to thereby turn the lever 0, pivoted at 0 andcause said lever to act against the portion 6 of the right-angled extension of the lever b and throw the shipper-lever out of its notch, thus releasing the friction immediately.

To stop the loom when the shuttle fails to be boxed, the lay is provided at its under side with a dagger-shaft f, having a dagger f, and said shaft has a projection upon which is mounted the usual binder-finger that bears on the shuttle-box binder f The finger is kept normally in contact with the binder by a spring of usual construction surrounding the shaft f, (not shown,) so that whenever the shuttle fully enters the box the shuttle moves the binder outwardly and acting through the binder-finger puts the dagger in its inoperative or dotted-line position, Fig. 4. Should, however, the shuttle fail to fully en ter its box, then the binder will not be moved outwardly, and the dagger will stand in its full-line position, Fig. 4. The dagger when in its full-line position, Fig. 4, will strike and move a slide f longitudinally on usual sustaining means and will cause a projection f of said slide to act upon one end of a short lever f mounted on astudf, and will turn the short arm of said lever then in contact with the usual lever f pivoted at f on the under side of the breast-beam, and will move the latter lever in the direction of the arrow, Fig. 55, causing its outer end in contact with the right-angled portion of the arm 6 to move said arm in a direction to disengage the shipper from its usual holding-notch, which will not only release the friction-clutch members to stop the loom, but will also release the lever d, that the brake may be put upon the brake-pulley. This movement of the lever I) disengages the notch 6 of the right-angled portion 5 from the projection (Z, extended from the auxiliary lever cl, mounted to turn on a stud D permitting through rod (5* the expanded spring (Z surrounding the bolt (Z to move from the position Fig. 2 into the position Fig. 3, causing thebrake to meet the brake-pulley A and immediately stop the loom.

To enable the effective strength of the spring (Z to be increased, the bolt 6Z6 has a head cZ ,and said bolt just below its head is of other shape than round, preferably square. as shown in Fig. 4, and fits a square hole (Z13 in a portion of the loom-frame. The threaded lower end of the bolt below the spring has attached to it a spring-rest e and an adjustingnut e, and to increase the tension of the spring it is only necessary to turn the nut on the non-rotative bolt. If the bolt was capable of being rotated in a round hole in the loom-frame instead of a hole other than round, as herein illustrated, it would be necessary to also hold the bolt when the nut was to be rotated. As the lever (Z is moved from the position Fig. 2 into the position Fig. 3 it raises, through the plate 4, a manually-controlled rod D, and the loom having been stopped and the operator desiring to turn the crankshaft by hand must first remove the brake from the brake-wheel, and to do this it is necessary only to depress the manually controlled rod D and move the auxiliary lever cl from the position Fig. 3 into the position Figs. 1 and 2. As the lever d is moved by the rod D the projection (Z is moved downwardly in contact with the right-angled portion of the arm I) until the stud comes opposite the notch therein, when said arm then under the influence of the springing shipperlever will engage said projection and hold the brakelever in its inoperative position, as raising the rod (V turns the lever (Z so that the shoe (Z 7 will be removed from contact with the brake-pulley. In this condition the crankshaft may be turned by hand in usual manner. one has only to move the shipper-lever to en gage its holding notch.

Having described my invention, what I claim, and desire to secure by Letters Patent,

1. In a loom, a shaft having a brake-pulley, a pivoted brake-lever, a non-rOtative bolt threaded at its lower end and extended loosely To start the loom running properly,

'rraoee through the end of said lever behind said brake-pulley, a nut on said threaded bolt, and a spring interposed between said nut and the under side of said brake-lever whereby by turning said nut on said non-rotative bolt the pressure of the spring for actuating the brakelever and forcing it against the brake-pulley may be regulated as desired, combined with a manually controlled rod, a lever actuated thereby, and a link uniting one end of said lever with the front end of said brake-lever.

2. In a loom, a shaft having a brake-pulley, a pivoted brake-lever, a non-rotative bolt threaded at its lower end and extended loosely through the end of said lever behind said brake-pulley, a nut on said threaded bolt, and a spring interposed between said nut and the under side of said brake-lever whereby by turning said nut on said non-rotative bolt the pressure of the spring for actuating the brakelever and forcing it against the brake-pulley may be regulated as desired, combined with a manually controlled rod, a lever actuated thereby, and a link uniting one end of said lever with the front end of said brake-lever, and means for locking automatically the lever actuated by said manually-controlled rod to hold the brake-lever out of contact with the brake-pulley.

3. In a loom, a binder, a shaft having a brake-pulley, a dagger controlled as to its position by the binder, a pivoted brake-lever, a brake-spring to force the brake-lever against the brake-pulley, an auxiliary lever located at the loom side, an adjustable connection between said auxiliary lever and said brake-le ver, means to lock the auxiliary lever in position to retain the brake-spring compressed, and devices intermediate said dagger and the locking means for said auxiliary lever to move said locking means and release said auxiliary lever when the brake is to be applied.

4:. In a loom, a shaft having a brake-pulley, a dagger controlled by the position of the binder, friction members coacting with said shaft, a shipper-lever, a notched plate for holding said shipper-lever in operative position, means moved by said dagger when the shuttle fails to be properly boxed to release the shipper-lever from its notch, a spring to move said lever outwardly when released, means controlled by said shi1L per-lever when moved outwardly to quickly disengage said friction members preparatory to stopping the loom, a pivoted brake-lever, a spring normally held compressed by said brake-lever when the loom is running, means to lock the brake-lever in its inoperative position, the releasing of the shipper-lever disengaging the means for locking the brake-lever in its operative position, and permitting its actuatingspring to expand and force the brake-lever against the brake-pulley.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
