To all whom it may concern.- 7

Be it known that W6,'WILLIAM H. BAKER, residing at Central Falls, Providence county, Rhode Island, and FREDERIO E. KIP, residing '5 at Montclair, Essexcounty, New J ersey, citi zens of the United States, have invented certain new and useful Improvements iii-Looms,

of which the following is a specification. T

This invention relates. to that class of de- IO vicesemployed for automatically supplying filling or weft to the shuttle of a loom; and it has for its object partly toemploy electricity for controlling and determining the supply of filling and partly to provide-simple and effil cient mechanical means for carrying out the invention, all as will be more particularly hereinafter described.

In the accompanying drawings, which serve to illustrate an embodiment of the invention,

Figure 1 is a front view of an ordinary loom provided with the'improved weft-supplying mechanism, the latter being represented in this view on a small scale. Figs. 2,3, 3, 4, and 5 are views of the Weft-supplying mech- 2 5 anism on-alarger scale, Fig. 2 being a fronts view as seenfrom the right in Fig. 3; Fig. 3, a vertical section substantially at line 00 in Fig. 2; Fig. 3, a fragmentary sectional view at line m in Fig. Zsimilar to'Fig. 3, but shows 0 ingthe bobbin-carrier in a different position;

Fig. 4, a horizontal section taken through theinclosing casing and carrier above rack 11, seen in Fig. 3; and Fig. 5, a fragmentary face view ofthe carrier, showing one of the fingers thereon. Fig. 6 is a side view of the shuttlebox, and Figs. 7 and 8 are respectively a plan and a side view. of the shuttle detached. These views are on a larger scale thanthe preceding figures. Fig. 9 is a sectional plan view, on a large scale, of parts of the shuttlebox, shuttle, bobbin-box, and bobbin, illus 'is fixedthe carrier 6.

shuttle, and FY in Fig. 1 the Weft-supplying mechanism asa whole. Respecting this latter mechanism, which is best seen in the detail views, l is astrong bracket mounted on the loom-frame, and 2 is an upright magazine which holds the bobbins, each inclosed in a bobbin-box 3. The bobbin-boxes rest one on they are taken from the bottom of the magazine one by one bya rocking carrier-and transferredto theshuttle S,the incoming bobbinboxdisplacing that already in the shuttle.

:Monnted to rock in bearings 4 at in Figs. 2 and 4 in the bracket 1 is ashaft5,ou which This carrier is in the form of a frame of quadrant shape, as'seen in Fig. 3, and carrying one section 7 of the semicylindrical inclosing casingythe other section '7 thereof being fixed in position and connected with the magazine 2. This magazine maybe composed, as here shown, of two like upright end pieces or keepers, in which the respective ends of the bobbin-boxes 3 are guided in their descent, as by gravity, to the point where the rocking carrier-frame 6 takes them.

It may be well to explain here that the bobbin-box 3 is of elongated form, of stilt thin material, preferably sheet-steel, and of such size and proportions as to fit into the hollow of the shuttle S. Each box 3 has formed in it a mortise or socket 3, Fig.8, near each end thereof, to receive flat carrying pinsor fingers 6 on the frame 6. As the lower bobbin-box descends from the magazine (see, Fig. 3) it engages the fingers 6, and is ready to be transferred to the shuttle.

The electrical devices will now be described.

On the lay L is mounted a stout, bracket 8, Figs. '3 and 3, which supports an electromagnet M, and an elbow-shaped armature-lever 9, carrying the armature m. The upper arm of the lever 9 has a toe 9, which when the magnet M is excited and-attracts its armature-is projected upward through an aperture in the horizontal arm of the bracket 8. The bracket 8 and magnet M move to and fro, the lay of. course being mounted thereon. 'Mounted to slide ina guideway in the bracket 1 is a rack 10, which plays directly over the bracket 8, and gearing with this rack is a circular another or superposed in the magazine, and

rack 1l,-fixed to the rocking carrier 6 and concentric with the shaft 5. Now if the electromagnet M be not excited when the lay advances in beating up the toe 9 will move in under the rack 10, and the carrier (5 will not be operatedybut if'the magnet be excited the toe 9 will be protruded upward and will impinge upon and take over the end of the rack 10, thus driving said rack back and through its engagement Wllll the gear or curved rack 11 rocking the carrier 6. The carrier moves forward the bobbin-box 3,wliich is engaged by the fingers thereon, (see Fig.3,) eventually driving it down into the shuttle and knockingout ordisplacing the bobbin-box 3 therein, which latter falls down through the open shuttle and a slotor'aperture in the lay. The shifting or changing of the bobbinboxes in the shuttle breaks the circuit, as will be hereinafter explained, and the armaturespring 9" withdraws the toe 9. On the return or back'movementof the lay the fingers (i are Withdrawn from the bobbin-box in the shuttle, and the carrier 6, now free, is returned to its normal position by a suitable spring 12. It may be well to state that when the carrier rocks forward to deposit a'bobbin-box in the shuttle the curved movable section '7 of the casing moves under the bottom of the magazine 2 and prevents the descent of the bobbin-boxes therein; but as the carrier moves back to the position seen in Fig. 3 the magazine is again uncovered and the lower bobbin-box therein descends and engages the upright fingers 6. One corner or angle 3 of the bobbin-box is rounded or cut away, so as to permit it to enter the shuttle readily, and the shuttle is open at its bottom to allow the bobbinbox to drop down through ,When displaced.

Referring to Fig. 6, which shows the shuttle-box on the lay in side elevation, 20 represents an electric circuit, and G a generator supplying same. This circuit may be arranged in any way known to electricians. On the shuttle-box are two spring-terminals '6 i of said electric circuit 10, and these terminals are adapted to bear, respectively, on contact-plates l3 and 13*, set in the side of the shuttle S, as best seen in Figs. 6 and 9. In the shuttle at its respective ends are mounted elastically-yielding holders for the bobbin-box 2. These hold the box in place by an elastic end pressure thereon, but yield and permit it to be knocked out by an incoming box, as already explained. At the right in Fig. 8 the wooden shuttle is broken away to show the wedge-shaped yielding metal holder 14 which is electrically connected bya suitable wire or the like with the contact-plate 13 and in Fig. 9 particularly the plate 18 is shown to be electrically connected in a similar manner with the yielding cone-shaped metal holder 14: at this end of the shuttle.

Figs. 9 and show the bobbin 15 in detail.

It may be of wood, as usual, and has at its larger end a flanged metal ring or collar 16, which is in contact with the metal bobbinbox 3. The box 3 is open at this end and the bobbin is inserted at said opening, The ring 16 is connected electrically by a conductor 17 with a metal collar 18 on the smaller'part of the bobbin. Thus it will be seen the collar 18 is connected electrically with the springterminal A when the shuttle is in its proper place in the box B, the connection being through the conductor 17, the ring 16, the metal of the box 3, and the metal holder 1%. Within the end of the bobbin, Figs. 9 and 10, is set and insulated a metal piece, block, or ring 19, coned to receive the holder 14, and to this ring or piece is electrically connected a metallic spring contact-piece 20, which oc oupies a slot formed in the bobbin, and its free end takes under or within the collar 18.

This contact-spring tends normally to spring outward at its free end into contact with the inner face of the collar, and as this would connect the collar 18 electrically with thecircnit-terminal 13 through the said spring 20, the ring 19, the holder 14, and the plate 13 obviously the circuit would be closed; but when the filling or weft is wound on the bobbin it bears on an exposed portion of the spring :20 and presses the free end of the latter inward out of contact with the collar 18, thus holding the circuit open so long as there is suffioient filling on the bobbin to overcome the elasticity of the spring 20. When, however, the filling is nearly exhausted from the bobbin, the spring 20 will overcome the slight pressure on it and move into contact with the collar 18, thus closing the circuit at that point.

This may happen when the shuttle is not in the shuttle-box B; but the instant the shuttle thereafter enters this box the spring contact-terminalsfand on the box will be put into contact with respective plates 13 and 13 on the shuttle, and this will complete the circuit through the electromagnet M. The-effect of the excitation of this magnet in effecting the operation of the carrier 6 has been described. As the circuit in the full bobbin is broken it will be obvious that when a fresh bobbin-box from the magazine enters the shuttle the operating-circuit will be broken. Thus the attendant will only be required to keep the magazine 2 supplied within-the bobbins in their boxes,.and the shuttle will be supplied with full bobbins automatically as needed. Moreover, as the circuit will be completed before the bobbin is absolutely denuded of weft there will he no weft-shot missing in the fabric and no fault.

Fig. 7shows how the thread from the bobbin is led out through the side of the bobbinbox. As here indicated, the weft thread or yarn 12 passes about a guide-pin 22 in the box and then out laterally through an aperture 23 in the side of the box, which aperture reg isters with a notch 24 in the side of the shuttle.

.15 invention is not limited strictly in that re- I spect.

' bobbin is denuded of filling.

In Fig. 9, y represents thread on the bobbin, wound over the contact-spring and hold: ing it out of contact with the collar 18. While in the magazine the weft-thread from each bobbin-box is led to a point z and attached the'reat.

Fig. 11 is a view showing another arrange ment of the contact-spring in the bobbin. 4 In this case the contact-spring 20 makes contact directly with the bobbin-box 3 when the Obviously many ways of efiecting this object-namely, the closing of the circuit at the bobbin when'the latter is nearly or wholly denuded-would occur to any one skilled in the art, and this For example, 1 ig. 12 shows a springv contact 2O on the box 3 and adapted to make contact with the collar 18 when the bobbin is denuded of weft at this point. The free end of the spring 2O bears on the weft on the bobbin. 7 p

By the word bobbin as herein used is meant an y device for carrying the weft-thread or filling for a shuttle, such as cops, buttcops, and the like. p I

Our invention, it will be noted, relates to an electr icallycontrolled mechanism for supplying weft to a loom while the latter is running, the object being to avoid the necessity of stopping the loom' to supply .it with weft as the latter is used up in the Weaving. We are fully aware that an electrically-controlled weft-stop mechanism has been heretofore devised; but we are the first, so far as we are aware, in this fieldwhere the supply of weft "is kept up automatically while the loomis running at full speed, the supply beingcontrolled electrically.

In the drawings the carrier 6 is represented as moving through about a quadrant; but the invention is not limited to this'extent of movement of the carrier. Obviously it might move through moreor less than a quadrant. This extent of angular movementwas chosen merely because it conveniently permits of the magazine being set in a vertical plane.
