To all whom t may concern, i

B e it known that I, WILLIAM L. BARRELL,

-a citizen of the United States, and resident of Lawrence, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Looms, of which the following is a specification. v

This invention relates te looms, and its object is to automatically replenish the weft as often as occasion requires.

Of the accompanying drawings, which 'illustrate one form in which the invention end of a loom of which the lower end ofthe picker stick is b roken away to avoid concealing essential parts of the present imprdvemenf This figure shows the lay in its extreme rear position, where it would sometimes be when the exchange of shuttles is made. Fig. 2 represents a view, partly in elevation and partly in section, including a part ofthe bobbin magazine, the

may be embodie: Figure 1 represents an ft l lay, mechanism for transferring a full bobbin to=a/shuttle, and mechanism for carrying the loaded shuttle from loading position to the shuttle box on the lay. Fig. 3 represents, in elevation, the forward part of the loom frame, and in section the shuttle carrier. with a shuttle thereon in loading position, and a support for bracing the shuttle carrier so as to sustain the stress upon the carrier when a full bobbin is inserted into the shuttle. Fig. 4 represents a perspective view of mechanism for pushing the empty shuttle to loading lposition relatively to the carrier. Fig. 5 represents a vertical section Y through the lay and through the parts vwhich form the shuttle box, including a removable front and a shuttle ejector. sents a section similar to Fig. 5, showing the same parts in different positions. the shuttle. front being lifted to permit ejection of the shuttle, the latter being shown ejected and supported by a receiver which lifts it to the position indicated by dotted lines. Fig. 7 represents a perspective view of the shuttle receiver which is' included in Fig. 6. Fig. 8 represents a top plan view of the carrier which transfers the full shuttle from loading position to the shuttle box, and the empty shuttle from the receiver to loading Fig. 6 reprcthe empty-shutt e receiver in its elevatedposition about to deposit the empty shuttle upon the carrier. Fig. 10 represents a front elevation of a portion of the shuttle carrier in loading position, includng the support which is aiiiXed to the loom frame to sustain the stress of theloading mechanism. Fig. 11 represents an elevation of mechanism lfor actuating the loader.

The Same reference characters indicate the same parts wherever they occur.

The drawings show the present invention as applied to a loom of well known con-y struction, made by the Stafford Company, of Readville, Massachusetts, and it may be assumed that such construction and its operation are in 'accordance with standard practice of the aforesaid loom unless otherwise specified.

Referring first to Fig. 1, the frame of the loom is indicated at 12, and the lay is indicated at 13. The crank shaft which operates the lay is indicated at 14, and the connecting rod at 15. A rockshaft which supports the lay is indicated at 16, and one of the picker sticks at 17. The swords and the mechanism for operating the picker stick are v omitted for the sake of simplifying the drawings.

The weaving mechanism of the loom is driven by a suitable clutch which does not require illustration or description and which is controlled by a shuttle-changing stop-motion mechanism which causes disconnection of the clutch whenever the weft thread is nearly exhausted. A well known element of a loom of this type is a cam shaft 18 which remains stationary in the position shown by Fig. 1 so long as the loom is weaving. l This cam shaft is driven by well known clutch mechanism (not shown) whereby one complete rotation is imparted to it for the purpose of operating mechanism which removes one shuttle from the lay and inserts a shuttle containing a full bobbin. This shuttlereplacing mechanism is substantially the same as that now in the aforesaid loom except in certain details which will be hereinafter explained. `It will be sulicient for .that when the stopped, the cam shaft 18 is rotated `once and then stops simultaneously with the startfing of the weaving mechanism. During this single rotation voi the cam shaft the necessary exchange of shuttles is made and then the loom is once more set in operation for weaving.

Referring now to Figs. 5 and 6, which show the several members at the left end ot' the lay which form a shuttle box, the shuttle front is indicated at 19. This member remains in the position shown by lFig. 5 so long as the loom is weaving, but is lifted to the position shown by lll'ig. 6 when ever a changeot shuttles is necessary. Tt is affixed to a pair ot arms 26 which arms are aixed with relation to each other and mounted to swing about a pivot member 2l.v This pivot member is mounted in brackets aiixed to the lay, one,l of which brackets is indicated at 22. An arm 23 extending to the rear and ixed with relation t'o the arm 20 is connected by a rod 2t with a lever 25 (see l? ig. '1), near the bottom of the loom. This lever is mounted* upon a ulcrum 26 and is provided with a roll 27 which is adapted to be engaged by e. cam 28 on the shaft 18. The shuttle front and the connections just described are normally locked in the position shown by Figs. 1 and 5. A spring 29, the upper end oita which is connected to one ot', the arms 20 and t-he lower end of which is connected to one of the brackets 22 aixed to the lay, exerts a down- `ward pull on the arm 20 and consequently exerts an upward pull on the operating lever 25. lWhen the cam 28 depresses the lever 25, the shuttle front is lifted to the position shown by Fig. 6, and while it is in this position the shuttle 29 is ejected from the lay. This mechanism for lifting' the shuttle front, and the ejecting mechanism about to be described are both well known parts of the Staii'ord loom.

The ejecting mechanism is operated by the mechanism just described. An ejector is indicated at 30. lt is mounted upon an oscillatory carrier 31 which is mounted upon a pivot member 32. The pivot member is supported by a :fixture 33'mounted upon the lay. The carrier 31 has a forward extension in which is mounted a setscrew 34:. This setscrew is so located as to be engaged and lifted by a portion ci? one of the arms 20. and -when so lifted the ejector is moved from the jposition shown by Fig. 5 to that shown by Fig. 6. The ejector moves the shuttle from the lay, toward the front of the loom. A spring 35 connected in suitable manner to the ejector, returns the latter to worden the position shown by Fig. 5, when the shuttle front 19f4is lowered.

ln my invention the ejecting of theshut- I tle 29 transfers the shuttle to a receiver 36, shown best lby F ig. 7. This receiver normally occupies the position shown by Figs. 1, 5 and 6. l that it swings back and forth with the lay when the loom is Weaving, and is always in position to receive an ejected shuttle eX- cepting when an exchange ofshuttles is being made, at which time the' receiver is lifted to the position indicated by lFigs. 6

lt is connected to the lay so and 9, prior to the transferring of another shuttle into the shuttle boX. The function of this receiver is to receive and place the ejected shuttle upon the carrier which inserts the new shuttle. The receiver comprises two shuttle-supporting clips 37 which have lips 38 for the purpose of preserving the lateral position of the shuttle so that it will be deposited in the desired position upon the carrier hereinafter explained. The supporting clips 37 are spaced a con-r siderable distance from each b her and they nengage the shuttle near the ends of the latter. A clear unobstructed spacey is left between these supporting clips, for the shuttle carrier when the receiver deposits the ejected shuttle upon the carrier, as will be better understood after further description. The receiver also has clips 39 Whose function is to preserve the endwise relation yof the shuttle. rThese clips have converging extremities 40 whose function is to guide the shuttle into the receiver when the shuttle is being ejected. lf the shuttle is not in the desired endwise position when it is' to the position shown by llig. 9 and shown by dotted lines in Fig. 6, the new shuttle passes through the :trame of the receiver and doesnot engage the same.

The receiver is mounted upon the upper end of a swinging arm 4&2 Whose lower end is pivotally connected at 4 -3 to a lever et. The ulcrum 26 of the lever 25 serves also as the fulcrum for the leverde. A roll 45 mounted on the lever 44: cooperates with a cam 4:6 on the cam shaft 18. This cam lifts the 'arml e2 and the shuttle receiver, and the arm is guided by a stud t7 carried `by a bracket e8 a slot 49 in the arm, and the faces of the arm vwhich define this slot are so disposed as to cause the shuttle to move forwardly when moving upwardly, and move rearwardly l' s the empty shuttle to rise without striking the stud 43 which connects the .arm 42 and the lever 44 is'disposed close to and in vertical shuttle`v front 19. The weight of the parts just describedl is suflicient to cause them to descend when the cam permits. The pivot alinement with the axis of the shaft 16 about which the lay swings, so that the `relative movement of the receiver and the lay when the loom is weaving will be negligible. The receiver just described, and its operating mechanism, is anew element' in the present, invention.

element beingV indicated as a whole at 51,

and the stationary frame of the magazine at 50. The rotatable element is mounted upon a shaft 52, and the direction of rotation is indicated by an arrow in Fig. 1. Full bobbins'are indicated in Fig. 2 at 53. The rotatable element is rotated step byl step so as.

to carry the bobbins successively against a l stop and guide 54. Each bobbin as it moves spring a gainstthe stop member comes undera lever which for convemence may be termed a.

loader, since its function is to push thebobbin downwardly out of the magazine and into av shuttle supported beneath it.

The shuttles and bobbins vand the loader shown are well known and require no description other than a statement that the bobbin is held in the shuttle by well known v means and that theI operation of forcing a full bobbininto the shuttle at the top forces the empty bobbin out at the bottom. The

loader 55 receives its loading motion from mechanism hereinafter explained, and it is returned to the position shown by Fig. 2 by a which engages teeth 58 on the rotatable element of the lmagazine in such manner that the rotatable element is moved lone step by the upward movement ,of the loader. This operation is in no way different from the operation of well known magazines now in use.

Figs. 1, 2^and 3 illustrate a shuttle 59 in loading position. Theshuttle is supported in this position by'a carrier 60. (.lhls carrier is affixed to a swinging lever 61 whose fulcrum 62 is located. directly above and close tothe rockshaft 16 which carries the lay. Referring to Fig. 1, the fulcrum 62 is behind and concealed by the lower end of the -struction .which are new.

56. `The loader carriesa pawl 57' v a pair of supporting fingers 71 which pro-- shuttle to these fingers is effected by arm 42 and pivot 43. The function of the 65 l carrier 16 is'to carry a loaded shuttle tothe lay to replace the ejected shuttle, then to carry the ejected shuttle to the magazine, and support the empty shuttle during the loading operation. The proximity of the fulcrum 62 tothe axis about which the lay' swings causes' the shuttle on the carrier to describe an arc nearly concentric to the-arc described by thelay. The movement of the carrier when transferring a loaded shuttle from the magazine to the lay is effected by av spring 63, and this movement is controlled by thesurface 64 of a cam 65 on the shaft 18, the arm 61 having a rol-l 97 which engages the cam. The return Vmovement of the car-v rier is effected by the surface 66 of this cam. The use of this'carrier for taking an ejected shuttle to the bobbin magazine is new and there are certain details concerning its con- Its function in transferring a loaded shuttle to the shuttle box is old. Its construction is new inthat 'it is formed with an opening 67 through which the empty bobbin may drop when a full bobbin is placed in the shuttle. The structural details of the carrier are shown best by Figs. 8, 9 and 10. vIts' upper surface, indicated at 68 in Figs. Sand 9, supports the shuttle during the loading operation of the latter. The position ofthe shuttleI when being loaded is indicated byvdotted lines in Fig. 8, and the shuttle as shown in section in Fig. 2 is in loading position. The shuttle which is ejected from the shuttle box andraised by the receiver is deposited upon the loading sur- 100 face 68 of the carrier, the path of the empty shuttle when bein thus deposited being indicated in Fig. 9 y dotted lines a, a. The carrier has a flange 69 and spring clips 70 which preserve the lateral position of the shuttle when it is on the loading surface. The movement of the receiver36 is such as to deposit the shuttle between this fiange and the clips. When the carrier is in loading position, one of its ends (see Fig. 10) rests 110 upon a stationary support which is a affixed tothe frame 12 of the loom. The

. function of this support 120 is to sustain the lmade. the loaded shuttle 59 is first transferred from the surface 68 of the carrier to ject toward the lay.I The transfer ,of the mov' ingthe carrier away from the lay and by bin magazine, and its ends 74, as ,shown by Figs. 1 and 3, embrace the ends of the shuttle so as to prevent end-wise creeping of vthe latter. rlhe springA slips 70 may be easily flexed, and theyvl are depressed by their engagement with the sh'uttle when the carrier l @30 is moved to transfer rthe shuttle to the fingers 71. When the shuttle rests `upon the fingersits front side is engaged by shoulders 75 on the carrier and is moved positively into the shuttle box on the lay by theseshoulders.v

While being supported bythe fingers.

Figs. 1 2 and 4 show mechanism for moving the shuttle 59 against the ixed bar 73,

for the purpose ofinsurin ,the desired position of the shuttle for loa ing. This mechanism comprises a usher 76 which is shown in the form of a ro It is carried by a bell- 30 crank lever 77 which i's mounted upon the exterior of the magazine frame 50. f' The fulcru'm of this lever is indicated at 78. 'A rod 79 extends from the lever 77 to a pin 80 which is carried by alever 81. The fulcrum of the lever 81 is indicated at 821 in Fig.` 1. The upper surface of the lever l81 is for the most part curved, but `it has an inclined shoulder 83 which is in ei'ect a cam surface.

' This surface is disposed to be engaged by a 4u roll 84 mounted upon the carrier ever 61, When the `carrier moves from the lay toward the magazine with a shuttle which has' just been ejected from the shuttle box, the roll 84 strikes the cam surface 83 when thecarrier has nearly reached loading position. The free endof the lever 81 is depressed against thevtension of a springA 85 (Fig. 1), which spring is connected at its upper end. to a fix- 'ture on the frame 12 and at its lower end to the l 5@ pin 80r carried'by the lever. The' downward movement of the lever 81 causes the pusher` 76 to movetoward the fixed bar 7 8 and thus push the'shuttle against the bar if it is not already. in that position. The subsequent forward movement of the carrier whereby the loaded shuttle is transferred to the fingers 71 does not cause any further movement of fthe pusher 76, because the surface 86 which at this., time isengaged by the roll 84 is concentric with relation to the axis of the stud 62 upon4 which the carrier is mounted. The pusher therefore remains in the position shown by Figs. 1 and 2, and prevents tipping movement of the shuttle recense the ngers 71. When the shuttle has dropped to the fingers 71,l its top surface 1s below the pusher, so that it will;

pusher in moving toward the ay. When the roll 84 rides over the surface 83 of the lever 81 in moving toward the rear of the loom, the spring 85 lifts vthe lever 8l and syvlngs thepusher toward the rear and upwardlgJ so that the pusher will not obstruct the pat o'f the shuttle which will be carried from the lay to the magazine.

Upon the completion of the 'shuttle-exchanging operation, the power for operat- -ing the loom for weaving is automaticallyy connected and the power for driving the cam' shaft A18 is disconnected As previously stated, the clutches for connecting and disconnecting the` power in these two respects ass under the are well known' and are not shown by the accompanying drawings. Fig. 1, however, includes cam-operatedimechanism for moving a controller which sets the aforesaid clutches.l

For this purpose the camshaft is'provided with a startingcam 87 which actuates a le- -ver 88whose fulcrum is indicated -a't 26. This lever has an arm89 whose up er end engages a collar 90l aiiixedto a startmg rod 91. The forward end of this rod is pivotally .connected to a lever 92. The lever 1s affixed to 'a rockshaft 96v which extendsy across the front of the loom to the opposite end, wherel it is connected with the above-mentioned 'clutch mechanisms. When the parts` are in the position shown by Fig. 1, 'thepower for operating the loom has just been 'disconnected, and the power for operating the vcam shaft has just been connected, but the cams are shown in the position which they occupy when at rest.- When the exchange of shuttles has been made, the cam 87 moves the lever 88 in such manner as to move the rod 91 toward .the rear of the loom. This movement is utilized for the new purpose of o erating the loader 55rso that a full bobbln will lbe placed in the shuttle 59, and-the shuttle lso loaded will be ready to' be placed in the loom when the next exchange of shuttles is necessary.- For the purpose of operating the loader, the lever 92 is'provided with an nism is automatically stopped in accordance with the' usual practice when the lay is toward the rear, as shown by Fig. 1. This operation releases the clutch-controlling f mechanism and permits the loader 55 to rise. If there 1s no special spring for'moving the clutch-controlling mechanism it will.

65 during 'the transfer from the surface 68 to be moved by the spring 56 which lifts'the 13@ shuttle from the upper surface of the carrier to the fingers 71, and during this movement the cam 28 lifts the front 19 of the shuttle box on the lay and ejects the shuttle 29. The carrier w1th the loaded shuttle then starts toward the lay, and at the same time the receiver which Supports the ejected shuttle begins to rise, so that the carrier with the loaded shuttle may pass through the open frame of the receiver and deposit l the loaded shuttle in the shuttle box. In-

asmuch as' the carrier 60 is moved toward the lay by a spring, the coperative relation of the carrier and the lay will not be disturbed by any variation in the position at which the lay stops, because the carrier will always movetoward the lay until the surface 95 of the carrier is against the lay, as 'shown by Fig. 9. Consequently' the cooperative relation of the carrier and receiver 36 will not be disturbed, because the osition of the receiver is likewise varied y the position of the lay. When the carrier has moved to the .position shown by Fig. 9, the shuttle front 19 is dropped to the position shownby Fig. 5, thus conning the new shuttle. The receiver 36 now descends and' deposits the ejected shuttle upon the surface 68 of the carrier, and the receiver continues to descend sufiiciently to enable the shuttle to pass over it when the carrier moves forward toward the magazine. The carrier now moves forward to place the old shuttle in loading position, and as the shuttle is about to come to rest in loading position the pusher 76 is oper-l ated to push the shuttle against the fixed abutment 73. The cam 87 then actuates the starting mechanism, and this in turn actuates the loader which places a full bobbin in the'shuttle, the full bobbin ejecting the partially or completely exhausted bobbin already in the shuttle. About this time the power is connected for setting the loom in operation and is disconnected from the cam shaft 18.
