SPECIFICATION forming part of Letters Patent No. 636,706, dated November 7, 1899.- Application filed July 27, 1899- $erial No. 725,219. (No model.)

To all whom it may concern.-

Be it known that we, WILLIAM H. BAKER, residing at Central Falls, Providence county, Rhode Island, and FREDERIO E. KIP, residing 5 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 mechanism con- IO nected with a loom for supplying weft thereto automatically when needed; and the characteristic features of the invention are a stationary shuttle-magazine on the loom-frame, a rotatively-mounted shuttle-box on the lay I 5 having in it a plurality of concentric shuttle cells, a shuttle-placer which vibrates between the delivery-outlet of the magazine and the said box and supplies a filled shuttle to the latter as needed, means for imparting interzo mittent rotary impulses to the shuttle-box to bring the filled cell down to the raceway and to discharge simultaneously the exhausted shuttle, and electromagnetic means for controlling the movements of the shuttle-placer.

In the accompanying drawings, Figure 1 is a front elevation of a part of a loom, showing our invention. Fig. 2 is a sectional side elevation taken substantially at line in Fig. 1.

Fig. 3 is a detached view, on the same scale 0 as Figs. 1 and 2, showing the latch-hook lifter. Fig. 4 is an end view, on a larger scale, of the rotary shuttle-box, showing the devices for rotating it. Fig. 5 is a fragmentary side view of the same, and Fig. 5 is a cross-section of the same. Fig.6 is a front view of the shuttle-box, enlarged, showing the electrical connections. Fig. 7 is a plan view of the shuttle, showing the bobbin in section and the electrical features within it; and Fig. 8 is a vertical section of one end of the shuttle. Fig. 9 representsa rotary form of magazine, which is preferred.

A represents the loom-frame, and a the breast-beam thereof. B is the lay, and b one of the lay-swords. b is the swing-rail, and G is one of the'picker-sticks. All of these parts may be of substantially the usual construction.

On the loom-frame is mounted a shuttle- 5o magazine D to contain the shuttles F. This magazine has its delivery-outlet at its bottom, and on the lay is mounted a rotative shuttle-box E. This box has a plurality of concentrically-arranged cells e for the shuttles-four, as herein shown-and turns on a shaft or rod mounted in brackets e on the lay. The cell 6 that is for the time below and adjacent to the raceway of the lay receives the shuttle in play, and the others are closed at their outer ends bya stationary ring-plate e mounted on the lay.

G is a vibrating shuttle-placer, which is mounted on the upper arm of a lever g, fulcrumed c on the loom-frame. Below the delivery 6f the shuttle-magazine is situated a receiving-shelf g for the shuttle which is to be delivered to the shuttle-box. This shelf is secured to the breast-beam a conveniently and is in the form of a bracket. It is situated below the outlet of the magazine D a distance sufficient to allow the lower shuttle to drop out clear of the magazine. By a vibrating moyement of the lever g the placer G is caused to push the delivered shuttle (F in Fig. 2) into the empty cell of the shuttle-box E, which stands opposite to it, a plate g on the placer moving under the magazine-outlet and preventing the shuttles therein from falling down until the placer returns to its normal position under the magazine.

When the shuttle in play becomes exhausted of weft, or nearly so, an electric circuit is closed by the entry of the exhausted shuttle into the lower cell of the shuttle-boxE at the picking-point and a magnet H on the loomframe is excited. This magnet, which is situated adjacent to the lower arm of the lever g, Fig. 2, attracts its armature h, which is carried by an armature-lever h,pivotally mounted on the lower arm of the lever g, thus drawing said armature-lever down to a substantially horizontal position. The lay B in beating up causes a tappet cl on the lay-sword to impinge upon the end of the armature-lever and throughit to drive back the lower arm of the placer-lever g, thus causing the placer G to move up to and place the shuttle F in the cell opposite to it in the shuttle-box E. The electrical devices connected with the shuttle and shuttle-box will be hereinafter OF CENTRAL FALLS, RHODE ISLAND, AND FREDERIO E. KIP, OF MONTCLAIR, NEW JERSEY.

described. Now when the lay recedes after beating up a partial rotation of the shuttle box E is eifected for the purpose of bringing the cell thereof, which will then contain the full shuttle F down to the raceway on the lay, and also to expel or throw out the exhausted shuttle,and the mechanism for effecting this shifting of the shuttle-box will be next described.

In one end of the shuttle-box E are set four short studs t', one for each cell c therein, and on the loom-frame, and preferably on the breast-beam a, is hinged a hook I, the hooked end of which is adapted under certain conditions to take over and engage one of said studs t'. However, normally or when the loom is running with a full shuttle this hook I is held up out of engagement with the studs i by a device best illustrated in Fig. 3. This lifting device consists of an inclined campiecej on the placer G, which when the placer is drawn back to its normal position by the strong retracting-spring J, Fig. 2, wipes under a stud or part on the hook I and slightly elevates it, holding it thus elevated until the placer moves inward toward the shuttle-box, when the hook is depressed by a light spring i into engagement with a stud i. As the lay moves back the hookl turns the shuttle-box nearly to the proper extent, when a spring device K (seen in Fig. 1) continues the movement. This device comprises, as herein shown, a member 7:, fixed to the magazine and having four radially-arranged V-shaped teeth and a like matching-member 7c, splined on the fixed shaft Z, about which the shuttlebox rotates, and backed by a spring Z This spring device is not in itself new, and any equivalent device for the purpose may be employed. \Vhen the movement of the lay shall have rotated the shuttle-box E to the proper extent, or nearly so, the hook I will be cammed off from the stud t' laterally, it being made sufficiently thin and spring-like for this purpose. The cams a which effect this, are on the end of the shuttle-box and so placed as to bear on the face of the hook, which is next the shuttle-box. As soon as the lay recedes the placer will return to its normal position. As the shuttle-box is rotated to the left, as seen in Fig. 2, the cell therein containing the full shuttle passes down behind a suitable curved guard at on the lay, which serves to prevent said shuttle from falling out of the cell, and the cell containing the exhausted shuttle is turned up and the said shuttle thrown out therefrom. It may be caught in a tray or other receptacle suitably placed to receive it. lVe have not deemed it necessary to illustrate this receptacle, as it is not essential to the invention.

In Fig. 2 we have shown what is known on looms as the protecting-finger, a common device for effecting the stoppage of the loom where the shuttle fails to enter the shuttlebox when it should do so. This finger a may be used in connection with our rotary shuttle-box and will be merely pressed back out of the way when the box rotates in shifting.

The electrical appliances are best illustrated in Figs. 2, 5, 7, and 8. On the side of each cell of the shuttle-box E are secured two spring-contact terminals 0 and 0 and on the lay B are secured two contact-pieces p and 9 which contact with the terminals on the box side, as seen in Figs. 2 and 5. The contact-pieces p and 19 are terminals of an outer operating-circuit formed by conductors 0' and 0 and including the electromagnet II and any generator L. The shuttle F has on its outer side, Fig. 7, two contactrplates qand q which when it is in play and enters the cell of the shuttle-box at the raceway come into contact, respectively, with the springterminals 0 and 0 on the side of the box. The plate q is connected electrically by a conductors with a springton the spindle M and behind a loose metal ring it on the spindle. The bobbin N slips on the spindle and carries in a slot therein a-curved spring-contact r, which when the bobbin is in place is put into electrical contact with the loose ring orwasher u. \Vhen the bobbin is in place, the weft O thereon presses in the spring-contact o and holds its free end out of contact with ametal ring or piece w on the bobbin and bridging the slot therein; but when the weft is nearly quite exhausted the contact 1; springs outward by its own resiliency and comes in contact with the ringw. This ring is connected by a conductor :13 with a grooved metal ring or piece 1 on the bobbin, and this ring is electrically connected through a conductors with the plate q on the shuttle. Thus when the break is closed in the shuttle by the exhaustion of the weft the circuit will be completed through the operating-circuit when the shuttle in play enters the box E.

The devices described and illustrated in Figs. 7 and 8 are the same in substance as those illustrated in our pending application, Serial No. 724,385, filed July 19, 1899, and are not specifically claimed herein. Indeed any one of the various devices shown in our several applications-name] y, SerialNo. 707,772, filed March 4, 1899; Serial No. 711,026, filed March 29, 1899;-Serial No. 723,128, filed July 8, 1890, and Serial No. 721,802, filed June 26, 1S99for closing a normally-open break in an electric circuit within a shuttle may be used in lieu of that herein described.

The preferred form of magazine (illustrated in Fig. 9) is rotaryin form and will need only a brief description. This magazine D is rotatively mounted within a stationary casing D. The box is in the form of a drum and has a series of conccntrically-arranged shuttle-cells d about its periphery. The lower cell discharges its shuttle down through a chute d, from which it falls to the platform or shelf g, and the placer G takes it as in the construction already described. At each movement of the placer back to its normal position a spring-latch d thereon rotates the magazine to the extent of one cell, said latch engaging one of a series of pins 01 on the end of the drum. A spring-detent d steadies the drum and holds it when set, the detent wiping over and engaging one of said pins d Preferably the placer G will be hinged on the lever g, so as to allow a little rocking of the placer thereon. This is desirable, as the placer moves in a slightly-curved path.

The spring 2' which depresses the hook I, is only a precautionary device. Gravity may be relied on to depress the hook. The length of the hook I will be such that it may wipe over and engage the proper studion the magazine when the lay is in the beating-up position.

In the drawings the fixed t-appet dis on the lay and the lever h is on the placer-lever g, the magnet H being on the loom-frame; but it will be obvious that the particular positions of these parts are not important so long as they perform the functions required of them.
