- connected by a ring Z, thus leaving the inner To all? whom it may concern:

Be it known that We, WILLIAM H. BAKER, 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 thefollowing is a specification.

This invention relates to double-shuttle looms, and has for its object to provide means for supplying weft to the shuttles or weftcarriers of the loom as required through mech-' anism automatically controlled by exhaus tion-indicating devices made inoperative and,

operative, respectively, by. the presence or absence of weft or filling in the active shutties.

In the accompanying drawings, which illustrate an embodiment of the invention, Figure 1 is a side'elevation, on a relatively-small scale, of a loom provided with our improvements; and Fig. 2 is a front elevation of the lay, showing the shuttle-boxes and picking mechanism.. Fig. 3 is a sectional side view on a larger scale, showing the construction more in detail; and Fig. 4 is a sectional front view on the same scale as Fig. 3,'showing the magazine in vertical axialsection. Fig. 5 is 0 a view of the detent device detached. Fig.

6 is a detail View of the shuttle-box and shuttle therein as seen from the front. This view shows the electrical connections. Fig. 7 is a sectional View of the shuttle and of the bobbin orweft-holder therein. Fig. 8 is'anenlarged View of the detachable spindle for the weft-holder. I

a is the loom-frame, and b the breast-beam,

tively mounteda drum-like magazine M to carry the weft tobe supplied to the shuttles h in the boxes on the lay. This magazine consists of a head or end i, a sleeve-like boss j, and bars in, extending from said head parallel with the axis or boss, where theyare end of the magazine open. The bobbins m are held iu'place by suitable spring-clips 'n, so that the bobbins may be easily displaced laterally by drivers 0 and 0', which drive them into the shuttles in the respective boxes c and c, displacing therefrom the empty bobbins. The magazine is rotated through a belt 12, which is driven from a sheave g on a shaft 1' of the loom and takes over a sheave s, ro- 6o tati vely mountedon the bossj of the magazine. This sheave contains a spring i, one end of which is secured to the pulley and the other to the boss The magazine is held against rotation by a detent device, to. be

hereinafter described, and when the springt is wound up the belt 19 slips on the sheave 5. Therefore when the magazine is released it will be instantly rotated by the spring 6..

' The. detentdevice' is best seen in Figs. 3 and 5. Itcomprises two like rocking detents u and 10, carried on an arm '2), which projects from thebracket 9. Each detent rocks on a stud w, projecting out laterally from the arm '0 and they arecoupled together by a link x, the link takingfhold of the upper detent a back of the pivot and of the lower detent u in frontof the pivot,'so that when one detent rocks it rocks the other'detent in the opposite direetion. To prevent thedetents from rocking too far in,either direction, a stud y, extending'from the bracket-arm, engages a limiting-slot in the link as. The detents u and u take over the respective upper and lower bobbins m, presented at the deliverypoint in front of the drivers 0 0 and prevent the rotation of the magazine (in the direction of the arrow 2 in Fig. 3) so long as both bobbins are in place. If the upper bobbin be driven into the shuttle, the magazine will turn until '90 the lower bobbin takes theplace left vacant, the next bobbin below rising to take thelower position; but if the lower bobbin be displaced the magazine will rotate until the bobbin next below it takes the upper position-that 5 is, when the lower bobbin is displaced the magazine rotates to the extent of two bobbins.

The drivers 0 0 are fulcrumed at 1 on the loom-frame and have laterally-projecting 1oo heads which extend into the open inner end of the magazine, and each driver carries pivoted to it below said fulcrum an arm 2, which may by lowering it be put into the path of a tappet 3, carried by the lay. As herein shown, this tappet is fixed to one of the layswords and is broad enough to actuate either of the arms 2, which may be putinto its path. The respective arms 2are supported on armature-levers 4 and 4, carrying the armatures 5 and 5 of two electromagnets 6 and 6, and when either magnet attracts its armature the corresponding arm 2 is lowered into the path of the tappet 3, whereby when the lay beats up the driver to which said arm is attached drives the bobbin m in front of it at the delivery-point out laterally from the magazine into the shuttle, expelling at the same time the exhausted bobbin from the shuttle in thebox. The magnets 6 and 6 are in electric circuits 7, one of which is seen in Fig. 6, and the operation of the respective drivers is controlled by the presence or absence of weft in the respective shuttles in play. Referring to Figs. 6 and 7, the electrical construction will be described, premising that as each shuttle and shuttle-box is fitted up electrically in the same way a description of one box and shuttle will serve for both.

The shuttle'h has clips or spring-jaws 8 to keep the weft holder-or supporter m in place.

This is a known device; but in this instance the clips are arranged above and below and not at the sides of the device which holds the weft. This device comprises a laterally-compressible metal spindle 9, detachable from the shuttle, and best seen in Fig. 8. This spindle is provided with a headpiece 10,Which may be of wood, and about the latter are two metal bands or rings 11, which are embraced by the jaws 8. These latter hold the spindle firmly but detachably in the shuttle. The butt or end of the metal spindle is in electrical contact with a metal plate 12 on the shuttle, and the plate 12 is electrically connected bya suitable conductor 18 with a metal contact-plate 13 on the face of the shuttle at that end, while the jaws 8 are connected electrically by a suitable conductor 19 with a metal contact-plate 13 at the other end of the shuttle. Thus the head of the spindle 9 is in electrical connection with the plate 13 and the rings 11- are in similar connection with the plate 13. Fixed in electrical contact with the end of the spindle is a contact-spring 14, which forms the indicator and plays in a slot in the block 10 and tends normally to spring outward into electrical contact with one or both of the rings 11, thus closing the circuit between the plates 13 and 13. The actual holder of theweft is a butt-cop 15, which mav' be slipped on the spindle 9. This butt-cop (or it may be a full bobbin) has a groove into which the free end of the spring 14 enters when the cop is slipped onto the spindle. Now if the cop or bobbin carries weft 16, as

erator to supply the circuit 20'. by employing suitably-arranged conductors seen in Fig. 6, the spring-indicator 14 passes under the weft and is pressed inward, so as to break the contact between said indicator and the ring or rings 11; but when the weft becomes substantially exhausted the springindicator will again close the circuit by forming contact with the rings. Now when the shuttle enters its box the plates 13 and 13 will be put into contact, respectively, with spring-terminals 17 and 17 of the circuit, as seen in Fig. 6, thus completing the circuit through the electromagnet 6 or 6 belonging to this particular shuttle-box.

In Fig. 6, 2O designates any suitable gen- Of course one generator may serve for energizing both magnets. This will be understood by any electrician.

The construction of the drivers 0 and 0, the magnets, and the operating-tappet is substantially the same as those shown in our pending application, Serial No. 9,493, filed March 21, 1900, and is not specifically claimed herein.

The particular construction of the contact devices in the shuttle and bobbin is not material to our invention so long as it is controlled by the presence or absence of weft therein. The contact-spring'17, held out of contact manually at the break by the overwrapped weft, may be as illustrated in our United States Patent No. 637,195, dated November 14., 1899.

The pickers 21 and the picker-stick 22 (seen in Figs. 1 and 2) possess no special or novel features, and indeed any kind of picker devices suited to the purpose may be employed. The lay may be vibrated by means of cranks in the shaft 4" and connecting-rods r in a known manner.

In Fig. 4 the weft-end holder 23 is indicated, but is represented for lack of room as partly broken away. There is nothing novel in this feature.

, The novel feature-of automatically supplying from a rotatable creel, feeder, drum, or magazine when required at the same time or on the same pick of the loom both the upper and lower shuttle or either the upper or the lower shuttle of a double-shuttle loom, with a bobbin or weft-holder containing weft or filling to replace that substantially exhausted, the said mechanism being so constructed that when the upper shuttle has been supplied the magazine will automatically rotate, so that it moves up to the extent of only one bobbin or weft-holder and then stops, but when the lower shuttle has been supplied or when both the upper and lower shuttles happen to be supplied on the same pick of the loom the magazine will automatically rotate, so that it moves up to the extent of two bobbins or weft-holders and then stops, is of course equally-well adapted to a mechanically-controlled weft-supply as an electrically-controlled weft-supply-as, for example, the mechanically-controlled weft-supply illustrated invour pending application, Serial No. 15,786, filed May 7, 1900.

- By weft-holder, as herein expressed, is

- meant any receptacle holding weft or filling such as a weft or bobbin case containing weft or filling, or bobbin, butt-cop, cop, and the like containing weft or filling. 'lhe magazine herein illustrated is also adaptable to carry any known form of weft-holder.

By absence or substantial absence and exhaustion or substantial exhaustion of weft or filling from the shuttles in play, as herein expressed, is not necessarily meant the entire absence of the weft or fill-,

ing, but such degree of exhaustion as will allow the exhaustion-indicating device to perform its function. 1

The spindle 9 is split and laterally compressible, as in the common form of spindle used in shuttles.
