SPECIFICATION forming part of Letters Patent No. 659,950, dated October 16, 1900. Application filed November 8, 1899. Serial No. 735,647. (No model.)

To all 1072/0712 it IIMLZ/ concern.-

Be it known that we, WILLIAM H. BAKER, residing at Central Falls, Providence county, Rhode Island, and FREDERIO E. KIP, residing at Montclair, Essex county, New Jersey, citizens of the United States, have invented certain new and useful Impro vements in Looms, of which the following is a specification.

This invention relates to looms having means for automatically supplying weft or filling as needed to replace that exhausted, and particularly to the class of looms wherein a compressed aeriforin fluid is employed for picking or driving the shuttle through the I5 warp-shed.

The object of the present invention is to provide a means whereby when the Weft or filling in the shuttle shall be nearly or quite exhausted a supply of weft or filling shall be furnished to replace that exhausted. Means are also provided whereby if the shuttle in play does not get home in its boX or cell from some accident the loom will be stopped.

In a general way the principal feature of theinventionconsistsina rotatively-mounted magazine shuttle-box which will be filled, normally, with shuttles full of weft. One of the cells of this magazine will be at the picking or driving point or alined with the raceway, if there be one, and when the shuttlein play shall be exhausted of weft, ornearly so, and it enters this working cell it will set in action mechanism to shift said shuttle-box, so as to bring the next succeeding cell containing a fresh shuttle to the driving or picking point. The magazine shuttle-box may of course be rotated by any going part of the loom; but it is convenient to operate it by the reed or by the lay or batten, if there be one.

In the accompanying drawings,which illustrate an embodiment of the invention, Figure 1 is a front view of the loom, and Fig. 2 is a side view of the right-hand side thereof. These views are on a small scale and show only so in ueh of a loom as is required to illustrate the invention. Fig. 3 is an enlarged side elevation of the magazine shuttle-box, partly in section at its lower part, the aircompressing devices being also in section. Fig. l is a view of the same parts seen from trating a modification wherein is employed a zinc at each side thereof.

similar to Fig. 5, but with the magazine omitled, so as to better show the parts below it.

Figs. 12, 13, 13, 14:, 15, 16, and 17 are views illustratinga modification wherein the rotary magazine shuttle-box is carried by the lay, and Figs. 18, 19, 20, and 21 are views illus- 7o gravity-magazine on the lay. Fig. 22 shows a construction wherein the loom has a maga- Fig. 8 is an illustrative View of the means for rotating the magazine.

In the principal views, Figs. 1 and 2, Ct is the loom'frame. Z) is the breast-beam forming a part thereof. 0 is the reed carried by lay-swords cl. 6 is the rock-shaft or swingrail. f is the crank-shaft, which imparts a to-and-fro motion to the reed through the medium of connecting-rods g. All of these parts are or may be similar to those in the known forms of looms. In the construction shown in the principal views the shuttleboXes are stationary at the picking-point or non-vibrating. A cam-shaft it below the crank-shaftf is driven from the latter through the medium of gear-wheels t andj on the respective shafts. The wheel 2', as here shown, is one-half the diameter of the wheelj, and consequently the shaft h rotates at one-half the speed of the shaftf.

It may be stated here briefiy that the loom as shown has, Fig. 1, a rotative magazine shuttle-box 76 at one side and like means otherwise than this at both sides of the loom for picking or driving the shuttle. For simplicity of description the mechanism at the side of the loom where the magazine shuttlebox is situated will be described, premising that the mechanism at the opposite side, except as will be pointed out, is the same and is designated by the same reference characters.

The magazine shuttle-box k is rotatively mounted on a horizontal spindle mi, fixed in abracket n. It has a drum-like form and is provided with a plurality of concentricallyarranged shuttle-cells 0 parallel with its axis of rotation. The arrangement shown is such that the lower cell 0', called the working cell, is at the picking-point and will be alined with the raceway, if one be used, when the shuttle is picked or driven. Alined with the inner end of the working cell is a fixed shuttle receiver-and director 0, which will be by preference flared at its receiving end.

The shuttle is adapted to be driven or picked by compressed air, and the means herein shown for compressing acharge of air and applying it for picking the shuttle will now be described. On the cam-shaft h is a cam 19, which acts on an arm g on a rockshaft o and on this shaft.- is another arm 8, which is forked and takes under a collar on an upright piston-rod t, which extends upward into the cylinderu of an air-compressor.

Figs. 1 and 2 show the features above described; but the enlarged view, Fig. 3, shows the interior construction of the compressor. The rod if is fixed to a piston 21, .which is driven upward by the camp to compress the air and is retracted by a spring w. (Seen in Fig. 1.) In the piston are suitable valves, which allow the air to pass above the piston when it descends. A passage ccconnects the outer end of the working cell 0 with the upper part of the compressing-cylinder, and this passage is controlled by a valve y, which opens inwardly and is held up to its seat by a suitable spring 2. The valve y is coupled to the longer arm of a lever l in the upper part of the compressor cylinder, and the shorter arm of said lever has a depending nose 2, which when the piston nears the end of its upstroke is impinged upon by the latter in a manner to rock said lever and suddenly throw open the valve y, thus admitting the compressed air to the rear end of the working cell 0 to drive the shuttle 3 therein through the warp-shed to the opposite side of the loom.

the picking operations may alternate, as will be understood by those skilled in the art.

The shuttle-box 4. at this side, (the left in.

Fig. 1,) which corresponds to the working cell of themagazine It, will be fixed and may be integral with the part called the shuttle 5 receiver and director.

The means whereby the exhaustion of the weft in the shuttle in play controls the supply of a fresh shuttle and the operating mechanism controlled will now be described with especial reference to Figs. 3, 4:, and 5.

As before stated, there is a series of concentrically and longitudinally arranged cells 0 in the magazine and shuttle-box 7a, and these cells will be primarily filled with full shuttles. These latter may be inserted at one end of the drum of the magazine, and to facilitate this two semicircular end plates 5 5 are provided, which close over the respective ends of the cells in the upper half of the magazine. The plates do not or need not touch the ends of the magazine, and they are connected bya strip 6 with a suitable lifting handle or lever 7, fulcrumed on an arm 8 of the bracket n, which supports the magazine. This latter bracket is herein shown as fixed to or integral with the air-compressor cylinder, and the latter is represented as supported on a bracket 9 on the loom-frame.

By means of the handle 7 the end plates 5 may be lifted out of the way and the shuttles inserted in the cells of the magazine in, the latter being rotated to aiford access to the lower cells thereof. These lower cells may be closed at their ends by suitable fixed plates 10, one of which maybe secured to thedirector 0, and these two parts be secured to a bracket on the cylinder of the air-compressor or to any non-moving part.

To steady the rotating magazine is with its lower cell 0 alined with the passage 00 at its outer end and with the flared director at its inner end, the device seen in Fig. 3 may be employed. This device comprises a spring pin or latch 11, with a rounded end, which engages one of a concentric series of recesses in the end of the magazine 70. This pin fixes the alinementand steadies the magazine; but it does not prevent the latter from being rotated when a little force is applied. On the drum-like magazine are formed a series of ratchet-teeth 12, (see Figs. 4 and 5,) one for each cell 0, and with these teeth engages a a spring-pawl 13 on a slidable pawl-bar 14:, which has a retracting-spring 15. A sliderod 16 plays at its free end through an aperture in the bar 14, and when protruded the end of this rod 16 finds itself in the path of a tappet 17, carried. by a vibrating or going part of the loom, as the reed c, the raceway, or the lay-sword. When the reed heats up, the tappet 17 encounters the protruding end of the rod 16 and through it drives back the bar 14, thus causing the pawl 13 to impart. a rotary impulse to the magazine 7t, bringing the next succeeding cell 0 into operative alinement with the raceway. When the tappet 17 recedes, the pawl is retracted, its spring allowing it to yield and pass over the ratchettooth on the magazine.

To understand how the exhaustion of the weft in the shuttle acts to control the protrusion of the rod 16, it will be best to first de scribe the shuttle and bobbin, which are best illustrated in Figs. 9 to 11.

The shuttle is of an inclosed or tubular form, though not necessarily cylindrical. As herein shown, it is rectangular with conical ends, one end piece 18 being removable, so as to permit of the introduction of the bobbin or weft-holder 19. At its end it hasapertures 20 to admit air, a fastening 21 to secure the end piece 18, internal shoulders, as 22 and 23, to clamp on the head 24 of the bobbin and hold the latter firmly in place, and an aperture, as 25, in the shuttle-wall for the weftthread to pass through. In the present con struction the bobbin is hollow at its butt or head and has one or more apertures 26 in its wall, which open into a circumferential exterior groove 27, Fig. 9, so that when the weft or filling is wound on the bobbin this groove is filled with a mass of weft which pays off in weaving just before the bobbin is exhausted, thus uncovering the apertures 26 at one pick, so as to open a passage for air through the shuttle from the apertures 20 at one end to the like apertures at the other end. Normally when the shuttle enters the working cell 0 of the magazine shuttle-box it it encounters a cushion of air therein, which cannot pass back about its body, and this cushion of air so resists the entry of the shuttle as to stop it short at, say, the point indicated in full lines in Fig. 3; but if the weft be nearly exhausted the apertures 26 will be open, so that air may pass entirely through the shuttle. Consequently when the shuttle next enters the working cell 0 the air of the cushion will pass back through the shuttle in a measure, thus removing or much reducing .the resistance to the entry of the shuttle, and the latter under momentum will enter farther into the cell, as indicated in the detail view, Fig. 7. When this occurs, the shuttle-body wipes over a side spring 2b in the cell 0, which has a beak 29, that passes out through an aperture in the cell:wall and is adapted when the cell 0 is the working cell to impinge upon the horizontal arm of an elbow-lever 30, the pendent arm of which is coupled or jointed to the slide-rod 16. Thus when the weft uncovers the apertures 26 in. the bobbin the shuttle will enter the working cello far enough (see Fig. 7) to press down the side spring 28 and through it drive out the slide-rod 16 into the path of the t-appet 17.

As we are the first, as far as we are aware, in this field of invention, we claim this inven tion in its broadest sense, and we do not limit ourselves to any specific device for accomplishing the results. We would consider our invention practiced in a loom having a weft or filling changing or supplying mechanism wherein the shuttle or weft carrier is picked or driven through the shed by the agency of an aeriform fiuid.

\Ve do not confine ourselves to any particu-. lar form of shuttle or weft-carrieror any particular form of shuttle-box, shuttle-tube, or ejector-tube. By the word tubular we do not mean to imply that the box is cylindrical. It may have any convenient form in crosssection, as rectangular, circular, elliptical, polygonal, or irregular. It will be understood that the form of the shuttle or weftcarrier used will conform to, that of the interior of the shuttle-box. If the latter be cylindrical, the shuttle or weft-carrier will be of cylindrical form also; but if the box be square, polygonal, orelliptical in cross-section thecross-section of the shuttle will conform thereto.

The shuttle-box may of course be 0011- structed in any convenient way, out of any suitable material, and the lining therein may be omitted if the shuttle is made to fit closely enough to prevent too much leakage of air around it. There will be or may he a little leakage in order to avoid the formation of too strong a cushion of air in front of the incoming shuttle.

We may explain here that the shuttle 3 has in it a partition 31, in which is an aperture or apertures 32, controlled by valves 33,which may be of leather. The purpose of this device is to permit the air of the cushion in cell 7 o to pass through the shuttle in one direction only when the apertures 26 in the bobbin are opened. The reason for this is that the shuttle is designed to be so placed that it will enter the working cell 0 always with the end having the cap 18 foremost, and the air of the cushion may then pass back through the shuttle; but if the apertures 26 should, as they may, first become uncovered by the weft while the shuttle is in the box 4 at the opposite side of the loom the charge of air for driving the shuttle cannot pass through the latter by reason of the valves 33 and partition 31. Of course the shuttle might be reversed, in which case the valves 33 would be placed on the opposite side or face of the partition. In any case these valves operate as check-valves. The cells 0 will of course all be provided with side springs 28, and they will be or may be lined with chamois, velvet, or other soft packing material, as described in our pending application, Serial No. 735,648, filed November 3, 1899. The weft-threads from the several shuttles in the magazine-cells will .be led out and attached to a weft-end holder, comprising, as herein shown, pins 34, in a disk or ring 35, carried with the drum of the magazine At any time when the loom is at rest the weaver ma T place filled shuttles in any of the upper cells, removing at the same time the empty shuttles therefrom.

Should a shuttle from any cause not get home in the cell or box when it is picked, at protecting device is provided to stop the loom at the next beat-up of the reed. This device will now be described with especial reference 'to Figs. 3, l, 5, and 8.

In the side walls of the several cells 0 of the magazine 70 are apertures 36, (seen in Fig. 3,) and a convex-faced protecting-finger 37, in the nature of a swell, is so situated as to occupy the aperture 36 of the lower working cell 0. In the specific construction herein shown the finger 37 is fixed to a rock-shaft 38, having hearings in a fixed bracket, and to this shaft is fixed an arm 39. 'lhis arm is backed by an adjustable spring device 40, which tends to press the finger 37 inward and into the path of the shuttle entering the working cell 0. The arm 39 is coupled by a link 41 to an arm 42, hinged or pivotally.attached to a piston 43 in a cylinder 44, fixed on the loom-frame. WVhen there is no shuttle in the working cell 0, the spring device 40 will press the finger 37 in ward, thus serving to raise. the arm 42 until it is alined in the path of a tappet or dagger 45, carried by a lay-sword d or other vibrating part of the loom; but when the shuttle enters the working cell the finger 37 is pressed outward and the arm 42 so depressed therethrough as to be below the path of the tappet 45. As seen in the plan, Fig. 8, the piston 43 carries a brake-rod 46, to which is fixed a tappet or dagger 47, which when the piston is driven back into. the cylinder strikes a knock-oft lever 48, which sets free a shipper-lever 49 and stops the loom. The knock-oft and shipper lever and the mechanism whereby the shipper-lever stops the loom are very common and well known and will require no further description. Our invention resides mainly in the air-cushion device, comprising the cylinder 44, closed at its outer or rear end, and the piston 43 therein. In the ordinary devices employed for this purpose a metal spring is used; but the impact thereon is so great in a rapidrunning loom that a metal spring will not answer promptly and is often broken by the blow. The air-cushion serves to overcome this objection and responds quickly and without injury even in looms where the lay or going part moves with great rapidity. Fig. 2 shows a strap-brake 50 on a pulley 51 on the shaft f. The brakerod 46 is coupled to this strap 50, so that the brake is set simultaneously with the shifting of the shipper-lever. This braking device is not in itself new.

As has been said, the shuttle need not be cylindrical; but when it has this form it should be ballasted, so as to prevent it from turning axially in its passage through the warp-shed. This is shown and claimed in our pending application, Serial No. 735,648, filed November 3, 1899. Fig. 8 shows the tappet 17 in operation on the rod 16, and Figs. 4 and 5 show a raceway or batten 52 moving with the reed. This raceway or batten maybe employed or not, as desired. Our present invention is not restricted to its use.

In the construction described we have shown a non-vibrating shuttle-magazine or one not carried by or moving with the lay or reed; but our invention is capable of embodiment as well in a construction where the magazine moves to and fro with the reed or with the parts forming the raceway, if there be such parts.

'In Figs. 12 to 17, inclusive, a construction is shown wherein the rotary magazine shuttle-box is carried on and vibrates with the-lay or batten 52, which is extended to receive it. Fig. 12 is a front view, and Fig. 13 a side View, on a small scale, illustrating this form of the invention. Fig. 14 is an end view of the magazine and adjacent parts. Fig. 1.5 is a side view, partly in section, of the same parts. Fig. 16 is a plan and Fig. 17 a detail view. These are drawn to a larger scale than Figs. 12 and 13. In these views we have embodied in the modified construction several features which differ from those in the principal views. For example, the shuttles and sh uttle-cells in the magazine are represented as cylindrical, as shown and described in our pending application, Serial No. 735,648. The devices for supplying compressed air to pick or drive the shuttle are also substantially the same as those shown in our said pending application. The pneumatic mechanical controlling devices at the magazine shuttle box are also similar to those in our said pending application, except that they are adapted to rotate the magazine instead of to stop the loom. In this construction, Figs. 13 to 17, the bracket 11., which supports the magazine, ismounted on the lay 52, which is extended in a manner similar to that in ordinary looms for receiving the ordinary sh uttle-box, and said magazine is or may be constructed precisely as shown in the principal views. By Way of variation, however, the cells 0 are represented as of cylindrical form, and the shuttles 3 will be of course of the same form. The air used to pick the shuttle is contained in areservoir or holder 53, from which it flows to a vessel 54 by a pipe 55, controlled by a self closing cock or valve 56, and it flows to the shuttle box or cell by way of a rocking pipe 57, controlled by a cock 58. The cocks are opened alternately by a cam 59 on the cam-shaft 7t, driven from the shaftf by gear-wheels 2' andj. This construction is the same in substance as that illustrated in our said pending application. When an exhausted shuttle enters the working cell 0 of the magazine shuttle -box, it enters far enough to strike and press out- Ward a push-rod 60, Figs. 15 and 16, and this rod is coupled to one arm of alever 61, fulcrumed on the lay. To the other arm of this lever is coupled a rod 62, which has a hearing in a pawl-slide 63, mounted in a bracket 64 on the lay and provided with a retractingspring 65. The slide 63 carries a spring-pawl 66, which engages teeth 67 on the magazine 70. When the rod 62 is protruded thus by the shuttle through the pawl slide and the lay heats up, the protruding extremity of rod 62 encounters a fixed tappet 68 on the loom-frame and the pawl 66 (which is here shown as a push-pawl) acts to rotate the magazine It to the desired extent. The protection-finger S7 and its mechanism operate the same as in the construction of the principal views, except that in this modified form the finger 37 and shaft 38 move to and fro with the lay and the arm 39 has a slotted connection with the link :hl, so that the proper play of the parts is permitted. This is seen in Fig. 14. The reed and other vibratory parts of the loom may be arrested at the picking-point and allowed to dwell momentarily as the shuttle or weft-carrier is traversing the warp-shed. as explained in our before-mentioned pending application; but in Fig. 13 we show a somewhat different means for effect ing this dwell. Said means comprises a cushion or buffer 81 on the loom-frame, Fig. 13, which arrests the lay or reed at the picking-point before the crank 82, Fig. 13, has reached the outer limit of its throw, the remainder of the move ment of the crank being permitted by a strong spring 8 3, behind a block 8% on the crank-pin in the yoke of the connectingrod 85. This construction allows the lay or reed to dwell while the shuttle is traversing the warp. There is or may be two rods 85 and cranks S2 to operate the lay.

The magazine sh uttle-box need not necessarily be rotative nor need it be moved or shifted by a going part of the loom in order to bring a fresh shuttle into play. In Figs. l8 to 21, inclusive, a construction is illustrated wherein the magazine-box, containing a plurality of cells superposed in position, is mounted in guides on the lay and adapted to shift by gravity as permitted. Fig. 18 is a front view, Fig. 19 a sectional plan, Fig. 20 a fragmentary vertical section, and Fig. 21 an ei'ilarged detail view, of the detent device. In this construction the magazine 69 is mounted to play vertically in guides 70 on the lay 52, the cells 0 therein being super posed or arranged one above another. The

flared guide 71 is fixed on the lay, and the magazine is allowed to descend step by step to bring the several cellsinto alinement with said guide and with the raceway. A spring detent device for supporting the magazine (seen best in Figs. 18 andv 21) comprises a series of teeth or shoulders 72 on the magazineone for each oella detent '73 on the guide 70, and a spring 7% to hold said detent in proper engagement. The compressed air or aeriforni fluid for picking or driving the shuttle comes to the lay by way of a flexible or rocking pipe, tube, or hose 75, and a valve 76 controls its admission to the outer end of the working cell 0. This valve is held to its seat by the compressed air, and it has a stem 77,which extends out at the back in position to impinge upon a suitable tappet 78 on the loom-frame when the lay recedes to the pick ingpoint. The stem of the valve then encounters the tappet and opens the valve, thus admitting air to the cell. When a shuttle 3 enters the working cell under ordinary conditions, it will occupy the position seen in dotted lines in Fig. 12; but if the weft or filling therein be nearly or quite exhausted and the passage or vent therethrongh opened, as before explained, by such exhaustion the shuttle will enter farther into the cell and its end will strike and drive back a slide-rod 79. This rod has a U shape, and its other branch is coupled to the detent 73, so that the blow of the shuttle will momentarily drive back said detent and allow the magazine to drop; but the detent-spring will move the detent forward again in time for it to catch under the next shoulder 72 above. A protection-finger 37, similar to that before described, may be employed with this form of magazine. In order to facilitate the insertion of shuttles or weft-carriers into the magazine 6!), a hinged door or flap 80 is mounted on one of the upright guides 70 The other ends of the magazine-cells may be closed by a plate on the other guide '70.

It will be noted that we have shown a form of the invention where the magazine shuttlebox is stationary or non-vibrating and also forms where the same part vibrates with the lay or going part of the loom. We do not wish to give undue prominence to either construction. In looms for weaving certain fabrics it may be desirable to use one form, and in those for weaving other kinds of fabrics the other form may be preferred. We have also shown means for picking or driving the shuttle or weft-holder by a compressed aeriform fluid in lieu of a picker and pickerstick; but it will be obvious that the pneumatic controlling devices whereby the substantial exhaustion of the weft or filling in the weft-carrier acts to set in motion the Weft or filling changing or supplying mechanism is really independent in its operation of the particular means employed for driving the shuttle or weft-carrier through the shed.

It will be apparent that by placinga magazine shuttle-box 7c and all the mechanism for controlling and operating it at both sides of the loom the store of weft may be doubled, and this construction may be employed if desired. In Fig. 22 we have shown a construction of this character where a weft or filling changing or supplying mechanism is situated at both sides of the loom. This view in other respects is the same as Fig. 1. When two magazine shuttleboxes are employed, the valves 33 in the shuttle may be dispensed with.

Our pneumatic device for controlling the times of operation of the weft or filling changing or supplying mechauism-that is to say, the vent or passage for air in the weft-carrier or shuttle, which is opened by the exhaustion or substantial exhaustion of the weft or filling therein-requires a special form of shuttle box or cell, and this form of box or cell is also adapted for use where compressed air is employed for picking the shuttle, and hence we have shown in the drawings these two features combined; but the pneumatic controlling device is adapted for operation in any loom having a suitable shuttle box or cell wherein the air will be incarcerated by the entry of the shuttle therein. In order that the pneumatic control shall be effective, the shuttle must enter the box somewhat. in the manner of a piston in a cylinder.

Where an aeriform fluid under tension is employed to pick or drive the shuttle, the charge of fluid will be to some extent deflect.- ed laterally through apertures in the walls of the shuttle-director near its receivingend, so that the entire force of the expansion of the charge shall not be expended in the direction in which the shuttle travels; but we do not limit ourselves to this particular deflecting means. In our pending application, Serial No. 9,842, filed March 23, 1900, another means for deflecting the fluid is illustrated.

We have shown and described in this application pneumatic control; but we do not limit ourselves in this respect. Other controlling means are known and may be employed. Also other means for rotating the magazine or shuttlefeeder than that shown are known, and we do not limit ourselves in this respect. For example, another device for this purpose is illustrated in our application, Serial No. 6,143, filed February 23, 1900.

Being the first, as we believe, in this field of invention, we claim, broadly, and would consider as coming within the scope of our invention a mechanism for supplying weft or filling to a loom combined with pneumatic means controlling the times of operation of said mechanism and also such a,supplying mechanism combined with means for applying an aeriform fluid to pick or drive the shuttle and pneumatic means at the shuttlebox for controlling the times of operation of said mechanism.

By exhaustion or substantial exhaustion and presence or absence or substantial absence of the weft or filling in the weft-carrier in play we mean either the entire denudation of the weft-holder or such degree of denudation thereof as will allow the shuttle or weft-carrier to perform its functions as described. By a shuttle or weft-carrier we mean that instrument which carries the weft or filling or yarn through the warp-shed in the process of weaving, and by bobbin or weft-holder we mean that device in the shuttle on which is wound the weft or filling. This device or part is variously called a bobbin, a spindle, a cop, &c. Where there is a spindle, the cop or all cop will usually be slipped thereon.

We have shown herein means for picking or driving the shuttle with compressed air; but some of the features of the invention are applicable as well to other means for picking the shuttle-as, for example, with a pickerstick and picker, as shown in our pending application, Serial No. 6,143, filed February 23, 1900.

In our pending application, Serial No.
