AUTOMATIC FILLING-REPLENISHING LOOM- SPECIFICATION forming part of Letters Patent No. 790,430, dated May 23, 1905.

Application filed March 25, 1904. $erial No.'200,022.

To all whom it may concern:

Be it known that I, GEORGE HENRY HA- WORTH, a subject of the King of Great Britain, and a resident of Burnley, in the county of 5 Lancaster, England, have invented certain new and useful Improvements in Automatic Filling-Replenishing Looms, of which the following is a specification.

This invention relates to self-acting filling 1 replenishing looms; and it consists in improved arrangements of mechanism suitable for underpick-looms and adapted to insure the certain action of the change motion at high speeds of the loom.

I On the drawings appended hereunto the improved apparatus or motion is represented, only such parts of the loom being shown as relate to this'motion.

Figure 1 shows a vertical cross-section of 2 the shuttle-box and the magazine through the center and looking toward the outer end of the slay with the movable parts in the positions they normally occupy while the weaving proceeds the slay and magazine being 5 shown in the positions they occupy relatively to one another when the slay is approaching the end of its forward movement; Fig. 2, a similar section of the magazine with the parts in the positions they occupy when the change 3 of the filling-shell is to be effected. Fig. 3 is a section of the magazine through the center looking toward the inner end; Fig. 4, afront View of the magazine and parts of a loom actuating the same; Fig. 5, a side view of the fill- 3 5 ing-fork lever, and Fig. 6 a plan ofthe shuttle-box and magazine.

The filling-cops are inclosed in cylindrical cases or shells 1, and the shuttle 2, Fig. 1, has a through-slot from the top to the bottom 4 and is arranged as described in the specification for Patent No. 738,897. The slay-bot- ,tom 5 and shuttle-box bottom 4 have a vertical slot 3 cut through them. To the shuttlebox back 18 a casting 6 is fixed, inclosing with the shuttle-box front 15 a curved channel 7, adapted to hold a definite nu mber-say three cop-shells. The lowest shell 1 rests upon Supports adapted to be pressed back by it when it is pushed from above, for instance, on sliding carriers 12, pushed inward by 5 springs, Figs. 1 and 5. In front of the slot 7 two carriers 9 are formed on a bar 8, extending in front of the shuttle-box front 15 and having backward extensions 10, which can turn on studs 11, fixed in the ends of the casting 6. A spring 13 is placed round a bolt 14, which is suspended by its head on a lug 15, formed on the shuttle-box front 15, and passes freely through the bar 8. A nut 16 serves to tighten the spring and hold up the bar 8 with the carriers 9. These are formed with inclines at the front and concave recesses in their upper sides to retain a cop-shell 1 in the cavities and press it against two horns 17, cast with the top of the channel 7.

Opposite to the channel 7 a hopper or magazine 21 is fixed, which is adapted to contain a number of cop-shells and is fixed to a bracket 19, bolted to the'loom side 20. The hopper is open at the top and bottom and has also nar- 7o row opening 22'at the outer end for the ends of the filling-yarn, which is threaded through one end of each cop-shells 1, to pass through. The reserve shells contained in the hopper are supported on two concave carriers 23, 7 5 which are cast on a cross-bar 24. This bar is fixed at each end to a vertical bar25, adapted to slide up and down in guides 26. The cross-bar 24 is supported by a rod 27, which on the breakage of the weft is actuated in such a manner as to lower the cross-bar 24 and the shell 1, resting on the carriers, from the position shown on Fig. 1 into that shown on Fig. 2, when it is at a slightly lower level than the shell 1*,held on the carriers 9. The 8 5 shells resting on the bottom shell 1 are prevented from following it by two fingers 28, which pass under the second shell when the carriers 23 are lowered. This may be eifected in the manner shown on the drawings.

fingers 28 form the prongs of a fork, the stem 29 of which slides in guides 30, fixed to the foot 31 of the hopper, and is pulled toward the shells by a spring 32. Between the fingers 28 an inclined finger 33 is fixed to the fork, against which an incline Qnthe cross- The 9 A bar 24 presses when this bar is in its top position, as shown on Fig. 1, and thereby holds the fingers 28 back. When the cross-bar 24 is lowered, the spring 32 pulls the fingers 28 forward under the second shell in the hopper and holds it up, the fingers being pushed back again when the bar is raised again.

The down-and-up movement of the bar 24 may be effected in any suitable wayfor instance, by the mechanism shown on the drawings. The vertical rod 27 is connected at its lower end to a lever 36, which is fulerumed on a bracket 37, fixed to the loom side 20. On the opposite side of the fulcrum the lever is connected to a vertical rod 39 by a universal joint 40. The upper end of this rod 39 is attached to a lever 41, fixed upon the shaft 42, which carries the lever 43, to which the weftfork holder 44 is attached at the opposite side of the loom. When the filling breaks or gives out, this lever is turned toward the front by the filling-fork 45 in the well-known manner, the rod 39 is moved upward, and the rod 27, with cross-bar 24 and shell-carriers 23, downward into the position shown on Fig. 2. When the slay now beats up, the inclines on the carriers 9 first lift the shell 1 against the horns 17 and are then depressed by it, the spring 13 yielding. The shell 1 presses the shell 1 back till it takes its place, whereby the shell 1 in the curved channel 7 is forced down into the shuttle 2, the supports 11 giving way. The spent shell is thereby ejected from the shuttle and falls through the slot 3 upon an inclined chute 46, fixed to the slay-bottom 5, which guides it to the outside of the loom. The supports 12 move forward again as soon as the center of the shell 1 has passed them and support the other shells in the channel 7. When the change of shells has been effected in this and the filling-fork is released, a weight 38 on the lever 36 returns the several parts to their position of rest.

I claim as my invention- 1. In a loom, a slay having a shuttle-box formed with a curved slot extending upward and forward from the top, of a slotted shuttle in said box adapted to contain several cylindrical filling-shells, carriers pivoted in front. of the shuttle-box and adapted to support another filling-shell in front of said slot, springs adapted to secure said shells in their positions and means whereby the shell carried by the carriers will pass into said curved slot.
