VVEFT=REPLENHSHENG MECHANISM FOR LOOMS.

SFEJIFEGATIQN forming part of Letters Patent No. 666,385, dated January 22, 1901. Application filedPebruary 16, 1899. Serial No. 705.698. (N0 model) T 0 (tZZ whom it may concern.-

Beit known thatI, JEREMIAH KEITH, a citizen of the United States, residing at Providence, in the State of Rhode Island, have invented a new and useful Improvement in Weft-Replenishing Mechanism for Looms, of which the following is a specification.

The object of my invention is to provide efficient means for discharging the shuttle from the shuttle-race upon the breaking or failure of the filling-thread and the insertion of a fresh shuttle in its stead; and my invention consists in employing the momentum of the discharged shuttle for forcing the fresh shuttle into the shuttle-box.

It also consists in means for removing the picker out of the path of the shuttle upon the breaking or failure of the filling-thread and in special details of construction, as hereinafter set forth.

In the accompanying drawings, Figure 1 represents a front elevation of a loom provided with my improvement. Fig. 2 represents an end view of the same. Fig. 3 represents an enlarged detail section taken in the line 3 3 of Fig. 1. Fig. 4 represents an enlarged detail top view showing the connec tion of the weft-fork with the breast-beam. Fig. 5 represents a top View of the swinging arm which serves to cause the depression of the picker-staff and picker. Fig. (3 represents a top view of the bed of the hopper. Fig. 7 represents a detail view showing the mechanism for opening the shuttle-binder. Fig. 8 represents a top view of the horizontal lever by means of which the shuttle-binder is opened, and Fig. 9 represents an axial section of the bed of the hopper.

In the drawings, A represents the frame of the loom; B, the breast-beam; O, the lay; D, the cam-shaft; E, the crank-shaft, and F the pitman, which connects the crank with the lay. The weft-fork a is pivoted at the point a to the slide b, which is provided with a slot 1), adapted to receive the upright arm 0 of the bell-crank lever c, the said lever being pivoted at the stud c and having its arm (Z in engagement with the cam cZ upon the shaft D. The slide 1) is held in the block e, secured to the upper side of the breast-beam B, and

. at its outer end 8 en a es with the arm secured to the end of rock-shaft f, which is supported at the front side of the breast-beam B in the bearings g g, and upon the rockshaftf is placed the torsion-spring g, secured at one end to the bearing g and at the other to the adjustable collar 71,, the torsion of the said spring serving to carry the armf inwardly, and to the opposite end of the rockshaft f is secured the arm h, which engages with the arm i of the lever 1;, the said lever being secured to the upper end of the upright rock-shaft j; which is held in the bearingbrackets j j, attached to the loom-frame, and upon the rock-shaftj is placed the torsionspring 10, which is secured at one end to the bearing-bracket j and at the other end to the adjustable collar the 'said spring serving to carry the arm Z of the lever t" inward, the said arm being carried outward against the resilience of the spring by means of the outward movement of the slide 1). The arm Z is provided at its end with the turned portion Z, which upon the outward movement of the arm Zwill be brought in the proper line for engagement with the upper side of the downwardly-turned curved arm m of the bell-crank lever m, which is pivoted at the point 92 to the bracket '11, attached to the lay-beam, and connected at its upperend 0 with the shuttle-binder 0, located at the forward side of the shuttle-box, so that upon the engagement of the arm m of the bellorank lever m with the arm Z, as indicated by dotted lines in Fig. 8, the shuttle-binder will be drawn outward against the resilience of the shuttle-binder springp to allow the ready entrance of a fresh shuttle into the shuttle-box upon the discharge of the shuttle therefrom, the arm Z of the lever 2" passing over the arm m of the bell-crank lever m and opening the shuttle-binder at the forward beat of the lay. To the lower end of the upright rockshaftj is secured the curved arm p, (shown in Fig. 5,) which passes between the antifriction-rollers p of the joint-piece q of the toggle levers q q, one of which levers is jointed to the bracket r, attached to the loom frame, and the other to the arm r, which is pivoted to the frame at the point 5. The picker-staff s is held to slide in the socket-piece if, provided at one side with the slot t, the said picker-staff being provided with the stud M, which projects through the slot 25 and engages with the underside of the arm r, and by means of the downward movement of the arm 9* the pickeru, which serves to throw the shuttle, may be drawn downward out of the shuttle-box to allow the escape of the shuttle by the unobstructed continuation of its flight through the end of the shuttle-box, the upward movement of the picker-staff being effected by means of the bent spring a upon which the lower end of the picker-staff rests.

The inclined hopper a in which the shuttles a a (t are held preparatory to being fed to the shuttle-box, is supported by the standard O, which may be either secured to the floor at the end of the loom, as shown in Fig. 1, or attached to the frame A. To the projecting arm I) of the standard C is pivoted the bell-crank lever which is actuated in one direction by means of the spring 0 and in the opposite direction bymeans of the engagement of the dying shuttle with the butter 0 at the lower end of the arm (1 and the outer end of the arm (Z is provided with the slot 6 which incloses the stud c projecting from the face of the slide f The sl1uttleforcerf is attached to the slidef by means of the rods g g which are held in proper adjustment by means of the set-screws 9 The opposite endsof the hopper a are provided with the side guides h 7L2, which serve to retain the deposited shuttles in position endwise. At the lower end of the hopper a are arranged the rock-shafts 01 a, provided with the inwardly-directed wings a a which serve to support the lower shuttle 0, of the series until the said shuttle is forced into the shuttle-box 2' by the downward action of the forcer f. The wings a a are caused to support the shuttle by means of the torsionsprings 71, 71 arranged upon the outward projection of the shafts C64 a, and the shuttle is forced downward between the wings a a upon the downward movement of the shuttleforcerf caused by the impact of the flying shuttle a upon the butter 0 of the lever h I claim as my invention 1. In a loom, the combination of the lay, the weft-fork, and means for actuating the shuttle through the shed, with means connected with the weft-fork for withdrawing the shuttle-actuating means, and allowing the shuttle.

to pass directly through the shuttle-box without deflection.

2. In a loom, the combination of the lay and the picker-staff with the weft-fork and means arranged between the picker-statf and weftfork for moving the picker-sta'lf out of the path of the flying shuttle, substantially as described.

3. In aloom, the combination of the lay,and the hopper for holding the shuttles, of means for causing the impact of the discharged flying shuttle, to force a shuttle from the hop per into the shuttle-box, substantially as described.

4. In a loom, the combination of the lay, the shuttle-bog. the shuttle-binder, and means for actuating the shuttle through the shed, with means connected with the weft-fork, for withdrawing the shuttle-actuating means to allow the discharge of the shuttle from the shuttle box and for opening the shuttlebinder at the forward movement of the lay, substantially as described.

5. In a loom, the combination of the lay, a shuttle-box thereon, and the shuttlebinder, a hopper, and devices operated by the flying shuttle for transferring a shuttle from the hopper into the said shuttle-box, at the for ward movement of the lay, with devices to open the shuttle-binder prior to the passage of the flying shuttle through the sh little-box, and to close the binder upon the subsequentlyinserted shuttle, substantially as described.

6. In aloom, the combination of the lay, the picker staff, and means for operating the same,with ahopper held independently of the lay, a forcer and the shuttle actuated by the picker-staff to cause the transfer of another shuttle from the hopper to the shuttle-box, substantially as described.

7. A shuttle-feeding apparatus, consisting of a hopper, a forcer, and an actuating-lever provided with a hunter adapted to receive the impact of the flying shuttle, substantially as described.
