STOP-MOTION FOR LOOMS.
SPECIFICATION forming part of Letters Patent No. 402,767, dated May 7, 1889.
Application filed February 6,1888. Serial No. 263,185. (No model.)
To aZZ whom it may concern.-
Be it known that 1, ANDREW J. PIROTTE, a citizen of the United States, residing at Manton, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Stop-Motions for Looms, of which the following is a specification.
The object of my invention is to prevent smashes caused by the meeting of two shuttles; and it consists in the improved construction and arrangement of the protector and its accessories and in improved devices for operating upon the shipper-disengaging le ver, to cause the disengagement of the shipper and consequent stopping of the loom whenever two shuttles occur at the same time in opposite shuttle-boxes at the ends of the lay, as hereinafter fully set forth.
Figure 1 is a detail front elevation of the lay-beam, showing the protector rods and fingers, which serve to operate the protector. Fig. 2 is a detail transverse section taken on the line 00 0c of Fig. 1 through the lay-beam and breast-beam, showing the attached parts of my improved stop-motion mechanism. Fig. 3 is a similar section taken on the line 00 9c of Fig. 1, showing the protector in engagement to stop the loom upon the failure of the shuttle to reach the shuttle-box. Fig. 4 represents a detail plan view of the stop-motion mechanism, the lay-beam and the breast-beam being shown in broken lines. Fig. 5 is a detail view illustrating parts of the mechanism. Fig. 6 is a detail top view showing a portion of the breastbeam with the shipper-lever disengaged from its notch.
In the accompanying drawings A represents a portion of the lay-beam, and B a corresponding portion of the breast-beam, of a loom. The duplicate protector-rods G O are each attached to the front of the lay-beam by means of bearing-pieces D D, the outer ends of each of the said rods 0 0 being provided with a pressure-finger, E, which is thrown back; by the entrance of the shuttle into the shuttlebox, and upon each of the rods 0 O is placed the torsion spring S, which serves to hold the pressure-fingers E against the shuttle-binders.
To the bracket F, attached to the middle portion of the lay-beam A, is pivoted the dagger G, which, upon the forward movement of the lay, serves to engage with the end a of the shipper-disengaging lever H whenever the said finger is not properly depressed by the entrance of the shuttle into the shuttle-box. The dagger G is held in its horizontally-elevated position by means of the flat spring I, and is operatively-connect-ed to each of the protector-rods O C by means of the deflected fingers J J, which are made to rest upon the upper surface of the spring-operated dagger G, so that each of the said fingers J J may serve to cause the downward movement of the dagger G independently of the other. Thus when the shuttle strikes into its box at one end of the lay one of the fingers J or J, which is in operative connection with the shuttle-binder 'r of the said box, will cause the downward movement of the dagger, and when the shuttle arrives at the opposite box the other finger J or J will serve to produce the required movement of the dagger, to prevent engagement with the end aof the disengaging-lever H, which serves to stop the further movement of the loom when the shuttle does not properly arrive at its box.
To the bottom of the breastbeam B is secured the bracket K, to the end of which is pivoted the weighted tripping-1ever L, which at its upper end, I), may be caused to engage with the edge of the shipper-disengaging lever H, to cause the proper disengagement of the belt-shipper H of the loom from its holding-notch b.
To the rear of the lay-beam Ais secured the bracket M, to which is pivoted the hook-lever N, which engages with the tripping-lever L to cause the required movement of the shipper-disengaging lever H when two shuttles are held at the same time in the opposite boxes of the loom.
At the point 0 on the hook-lever N, and transversely of the said lever, is pivoted the bar 0, which is adapted at each endto engage with the fingers P P, which extend backward from the protector-rods O O, the said fingers P P passing under the ends of the said pivoted bar 0, so that whenever one of the said fingers is raised it will simply cause the tilting of the said bar upon its pivot; but when both of the said fingers P P are raised together the outer end of the hook-lever N will be raised into engagement with the lower end of the tripping-lever L, so that the continued backward movement of the lay will cause the forward movement of the upper end of the saidlever L and the consequent movement of the shipper-disengaging lever 11 to stop the loom, and this result will always be produced whenever there occurs a shuttle in the opposite boxes of the loom to act simultaneously upon each of the pressure-fingers E E, thus effectually preventing smashes caused by the presence of two shuttles in the shed.
The loom with my improvement will thus be caused to stop both for the presence of a shuttle in the box at the wrong time and for the improper absence ofthe shuttle.
I claim as my invention- 1. In combination, the breast-beam, the shipper-disengaging lever, and the trippinglever, the lay-beam, the spring-operated dagger, the hook-lever provided with the trans versely arranged pivoted bar, the shuttlebinders, and the duplicate protectorrods, each provided with a pressure-finger resting upon a shuttle-binder, a finger resting upon the spring-operated dagger, a finger which opcrates upon the pivoted bar of the hook-lever, and a spring which holds the pressurafinger against the shuttle-binder, whereby the loom will be stopped either for the presence of a shuttle in the box at the wrong time or for the improper absence of the shuttle, substantially as described.
2. In combination, the breast-beam, the shipper-disengaging lever, and the trippinglever, the lay-beam, the hook-lever provided with the transversely-arranged pivoted bar and pivoted to the lay-beam, the shuttlebinders, the duplicate protector-rods, each provided with a pressure-finger resting upon the shuttle-binder, a finger which operates upon the pivoted bar of the hook-lever, and aspring which holds the pressure-finger against the shuttle-binder, whereby either of the pressure-fingers can be separately moved outward without imparting an engaging movement to the hook-lever, but the conjoint outward movement of both of the pressure-fingers will cause the engagement of the hook-lever with the tripping-lever and the consequent stopping of the loom, substantially as described.
AND BE \/V J. PIROTTE.
