LOOM.

SPECIFICATION forming part of Letters Patent N o. 637,695, dated November 21, 1899.

Application filed August 10,1892. Serial No. 726,756. tllo model.) V

To @ZZ whom t may concern).-v

residing at Central Falls, Providence county, Rhode Island, and FREDERIC E. KIP, residing at Montclair, Essex county, New Jersey, citizens of the United States, have invented certain new and useful Improvements in Looms, of which the following is a specification.

This invention relates to the class of looms provided with means for supplying weft thereto as required automatically and without stopping the loom.

In the construction herein illustrated the operation of supplying a full shuttle to the loom is in some respects similar to that illustrated in our pending application, Serial No. 724,385, filed July 19, 1899, in the respect that there is a shuttle-placer. operatedy by a cam on the loom and a displaceable shuttleboX on the lay; but in the present case the controlling electric circuit is closed by the entry of the shuttle into the displaceable shuttle-box and not by its entry into'the box at the oppositeside of the loom.F

In its general construction and mode of operation the invention as herein illustrated comprises a shuttle-magazine on a stationary part, usually theloom-frame, with a deliveryoutlet, a vibrating placer adapted to receive a shuttle from the magazine and carry it to the lay, where it is held until the shuttle is picked to the opposite sideb of the loom, a laterally-displaoeable open-bottomed shuttlebox onthe lay at the side `next to the magazine, which box` when displaced throws out the exhausted shuttle, a cam which operates these parts, and an electric circuit and electromagnet controlling the operation of the parts, this circuit having a break within the shuttle which is held open by the weft and closes when the bobbin or other weft-holder in the shuttle is nearly or quite denuded of weft.

In the accompanying drawings, which illustrate an embodiment of the invention,Figure 1 is a side elevation of a loom provided with our improvements and showing the positions of the parts under normal conditions, and Fig. 2 is a similar view showing the positions of the parts when the shuttles are being picker sticks.

changed. Fig. 3 is a front elevation of one side of the loom. Fig. 4 is a front elevation of the lay and the displaceable shuttle-box thereon. Fig. 5 is a side elevation, on a larger scale, of the displaceable shuttle-box, showing the electrical connections. Figf is a sectional view of the shuttle, showing the electrical connections therein; and Fig. 7 is an enlarged sectional View of one end thereof.

1 is the loom-frame, and 2 the breast-beam thereof. 3 is the lay, and 4 is one of the layswords. 5 is the swing-rail. 6 is one of the 7 is the crank-shaft, from which the lay is vibrated, and 8 is the connecting-rod between said crank and the lay. All of the above parts are or may be constructed substantially as in ordinary looms.

The shuttle-magazine 9 is mounted on the breast-beam or some other lixed part and has a delivery to the placer 10 when the latter is in its normal position of rest at or under the magazine. The placer is or may be in the nature of a trough with a bottom and two sides and is carried by supporting-arm l1, pivotally mounted at a; on the loom-frame. The displaceable shuttle-box 12 is suspended from above on ashaft 13, mounted to rock in brackets 14: on the lay.

15 is a lever which operates the placer 10 and shuttle-box'12 substantially simultaneously. To operate the placer, a connectingrod `16 couples the lever l5 with a branch arm 1191011 the supporting-arm 11 of the placer, and to operate the shuttle-box a connectingrod 17 couples the lever 15 with an arm 1S on the rock-shaft 13. The lever 15 is operated by mechanism similar to that shown in our above-named application-that is to say, a toothed wheel 19 on the shaft 7 gears with another wheel 2O of twice its diameter, this wheel 2O being iixed on a cam-shaft 2l, on

'mally plays close to a hook 26 on one arm of an elbow-shaped armature-lever 26, pivotally mounted on the lever 15 and bearing the IOO - lay .ordinarily occupied by the shuttle-boxlZ 'tl'e Sinthe shuttle-box and another` in .thee
