sively to the shuttle-changing mechanism, a brief description of the loom will be suiticient for present purposes.

The loom uses two shuttles alternately. While oneshuttle is traveling back and forth through the shed, the other shuttle is held 1n reserve; and when the filling in the worlr ing shuttle is about to run out, the weaving mechanism is automatically stopped through theaction of well known feeler mechanism.

The stopping of the weaving mechanism is followed by the operation of the shuttle changing mechanism, shuttle istaken away from the shuttle box and the reserve shuttle, containwhereby the spent ing a filled bobbin, is substituted for the spent shuttle. v The interchange of shuttles is followed by the transfer of the spent shuttle to loading mechanism which includes a bobbin magazine and means for transfer-- ring a filled bobbin from said magazine into the spent shuttle.

The weaving mechanism is automatically set in operation after the shuttles have been interchanged, and may continue in operation until another weft replenishing'operation is necessary.

The working shuttle and the reserve shuttle are indicated respectively at a; and w in Fig. 1. The reserve shuttle rests upon a sup port 10. The shuttlebox at the change end of the lay 11 includes the usual binder 12,

. the usual overhanging shuttleguard 12 and the movable shuttle-box front 13. Suitable clutch mechanism (not shown) which is commonly used in weft replenishing looms known as the Stafford loom, is controlled by feeler mechanism to stop the Weaving mechanism and to operate the replenishing mechanism whenever new filling is required. Inorderto permit the interchange of shut tles, the. movable shuttle-box front 13 is raised abgve the top of the shuttle, as shown by Figs. by arms 14 which are pivotally mounted upon a rod 15. This-rod is mounted in a bracket 16 carried by the lay Al n arm 17 rigidly connected to the arms 14 is connected by a link 18 withacam lever 19. The fulcrum memberof this lever is indicated at 20,. A roll 21 carried by the lever is arranged to be engaged by a cam 22.. This and 5. The member 13 is carried cam is affixed to a shaft 23, which shaft is sometimes termed the change shaft in, the Stafford loom liereinbefore mentioned. The cam raises the shuttle-box front and holds the latter elevated for a sufficient length of time to permit the removal of the spent shuttle and the deposit of the reserve shuttle, and the return movement of the shuttle-box 5 front is caused by atension spring 24.

Theautomatic stop mechanism is timed to cause the lay to stop at or near the position shown by Fi s. 1, 3 and 5. As soon as the shuttle-box ront 13 has been raised sufliciently to release the spent shuttle, the latter is ejected by ejecting mechanism which is shown-by Fig. 2. The ejector or shuttle-engaging member is indicated at 25. It is affixed to an arm 26which is mounted upon a pivot pin 27 arranged below and movable with the lay. The ejector is arranged to extend between theshuttle-binder 12 and the guard 12 thatoverhahgs the latter, and is curved so as to be substantially concentric in relation to the axis about which it swings when ejecting a shuttle. A stud or projection 28 carried by the arm is bored for the reception of a rod 29. The lower end of this rod is pivotally connected to a lever 30. This lever is arranged upon the fulcrum member 20 hereinbefore mentioned, and is provided with a projection 31 which is arranged to coact with acam 32'on the shaft 23. The effect of the cam is to raise the rod 29, and such movement of the rod is transmitted to the arm 26 by a helical compression spring 33. This. spring is arranged upon the rod and compressed between the stud 28 and a collar 34, the latter 35 being fastened to the rod. The spring 33 enables the ejector to stop in case the shuttle should. become caught, and permits the rod 29 to have its full upward movement without causing breakage or injury of the connections. Furthermore, the spring has a cushioning effect which lessens the force of .the im act of the ejector against the shuttle. It wil be observed that the point of initial contact between the ejectorand the shuttle is a substantial distance above the center of the shuttle. In the Stafford loom herein- A before mentioned,'the ejector is arranged to on age the shuttle initially near the bottom or e ow the center of the latter, such rela- 250 tion being due to the fact that in the stafl'ord loom the pivot about which the ejector swings is above the shuttle. One objection .to the ejector in the Stafford loom is that it .fsometimes causes theshuttle to tip over and 5 5 lie upon its side. This is due primarily to act that the shuttle-supporting surface ,klay is inclined considerably with relaon toa horizontal plane when the shuttle- ;i changing operation takes place. At such time the topof the shuttle 1s tipped toward e vrear of the loom, and the shuttle conseg uently tends to tip over'upon'its rear side.

his tendency *ejector, because the latter st 's the shuttle below the center. The tipping afthe shuttle is increased the Stafford,

in the Stafford loom is not especially objectionable, because the shuttle is not reloaded automatically but is merely discharged from the loom upon the floor or into a receptacle lying upon the floor. But in a loom which has mechanism for automatically reloading the spent shuttle, it is necessary to keep the shuttle always in coiiperative relation to the devices which act upon it. Itis for this reason that I have arranged the ejector, in the present instance, to engage the shuttle initially above the center, in which relation the initial tendency of the shuttle to tip back, due to the inclination of the shuttle-sup- )ortim surface of the la Y is neutralized.

It is not necessary that the point of contact between the ejector and the shuttle remain above the center of the shuttle throughout the ejecting movement; for when the inertia of the shuttle has been overcome, the tendency to tip over will not be sufficient to cause actual tipping. Fig. 2 includes dotted lines indicating the extent to which the ejector moves. From this it may be seen that the point of engagement between the ejector and the shuttle will progress downwardlywith relation to the shuttle; and that said point will be approximately midway between the top and bottom of the shuttle when the ejector has reached the limit of its ejecting movement. I

As the shuttle is ejected it passes from the lay to a receiver 35. A plan view of the receiver is included in Fig. 7. It has flange portions 36, 36' which are arranged to be engaged by the front side of the shuttle to prevent over-travel of the shuttle. The end portions 37 of these flanges are curved to cooperate with the end portions ofthe shut tle so as to register the shuttle endwise with 1 5 relation to the device by which the shuttle is subset; ently taken. The receiver has guiding flanges 38, 38 which are arranged toslide in guides 39, 39 carried by. the lay. The receiver is aflixed to the upper end of a rod or post 40, the lower endof which is guided by a member 41 which oscillates with the sword shaft 42. A member 43, is aflixed, to the rod 40 and is arranged to coact with a cam lever 44. The fulcrum of this lever is the member 20. hereinbefore mentioned. A boss 45 formed upon the lever rests upon a cam 46, said cam being carried by the shaft23. The effect of the cam is to lift the receiver 35, to'elevate the spent shuttle w as shown by Fig. 5 and as indicated by dotted lines in Fig.3. The spent shuttle is held in its elevated position for a sufficient length, of time to permit the shuttle carrier, hereinafter described, to carry the: reserve shuttle into the shuttle box. The shuttle carrier is indicated as a whole at 50, and it includes an arm or lever 51 and other details which will be described in due course. The arm 51 is arranged upon a sta-.

- from the support to the shuttle box of .ary in the position shown by Fig.

ne'raees carries a cam roll 53 which coacts with a q cam 54 on the shaft 23.

While the weaving mechanlsni IS in op eration theishuttle carrier remains station l and by full. lines in Fig.- 3; but in the course of changing the shuttles the carrier moves from the saidposition to the position shown by Fig. 5, thereby carrying the reserve shuttle the lay. This movement of the carrier is efi'ecte'cl by a helical tension spring 55, and the return movement of the carrier is effect ed by the cam 54.

The main body of the shuttle carrier has a shuttlesupporting surface 56 upon which the spent shuttle rests while being carried to thesupport 10. The reserve shuttle, in traveling from the support 10 to the shuttle box of the lay, does not rest upon the surface 56 but rests upon a pairof fingers 57.

Clhe rear ends 58 of these fingers are bent upwardly so as to engage the rear-side of the shuttle, as shown by Fig, 4 and by dot ted lines in, Fig. 3. The carrier is provided with a clamping device 60' by which the spent shuttle is held in place upon the sun face 56. The clamping deviceis pivotally mounted uponthe rod 61 which is afiixed to the carrier. A helical torsion spring'GQ is coiled about the rod, and one end thereof is hooked to the device 60 shown best by Fig. 9. The other end 63 of the spring: is arranged in a hole formed in a collar 64.

This collar is mounted upon the rod and is fastened thereto by a setscrew' 65. The collar is set in. aposition that will keep the device 60 constantly under s uingstress and normally-in contact with t e body of the carrier as indicated at 56. Th carrier is provided with a pair of upstanding cars 67 at its front side, in position to be engaged by the front side of thespent shuttle. The clamping device 60 has a pairv of ears 68 whose surfaoesfi?) are arranged to engage the rear side of the spent shuttle- Whenthe deviceGO is in its normal position as shown by Fig. 9, the distance between the surface 69 and the confronting surfaces of the ears 67 is slightly less than the width of the shuttle, and, in order to insert the shuttle between them it is necessary to de press the device 60 slightly against the stress of the spring 62., Consequentiy when the spent shuttle'is seated, upon'the surface 56 it is clamped against the ears 67 by the ears 68 and-is thus held with, sufficient force to prevent displacement. y

The clampingdevice 60 carries a pair of clampingdevices 7.0, 70 which coact respectively with ,the upturned cnds 58 of. the shuttle-supporting fingers 57 to clamp the filled shuttle. Thenxembcrs 70are connected to'the cars 68 by pivot pins 71. Headed studs 72 are aflixed to the clamping device 60 and extend loosely through holes 73 in the members 70. Helical compression springs 7d are arranged upon the studs 72 and are compressed betweenthe device 60,

and the devices 70, and force the latter toward the ends 58 of the fingersf57. The heads 7 5 of the studs are arranged to keep the members 70 from being forcedtoo far in the direction of the ends 58. When the -.Inembers 70 are in their normal positions as shown by Fig. 9, the distance between them and the confronting faces of the ends 58 is slightly less than the widthof the shuttle,

and it is necessary to force the members 70 away from the ends '58 in order to permit the-shuttle to rest upon the fingers 57 as shown by Fig. l. But when the shuttle is seated upon the fingers as shown by Fig. 4',

its rear side is clamped againstthe ends 58 by the stress of the two springs 74:, and the shuttle is thus held firmly upon the carrier during its passage from the support 10 to the shuttle box of the lay. Assuming that the weaviiw' mechanism has been stopped for replenishment of the weft and that the shuttle-changing mechanism has been set in operation as hereinbefore partly explained,-tlie carrier 50 moves.

from the position shown by Figs. 1 and 3 toward the layl The shuttle-supporting fingers 57 pass under the shuttle w" resting on the support 10, and the clamping members 70 engage the front side of the shuttle,

thereby'lnoving theshuttle toward the lay.

The inertia ofthe shuttle is sufficient to.

move the members 70 against the stress of the springs 74, and although the springs react almost immediately, the intervalfis sufficient to enable the shuttle to take its place.

in the angle of the fingers 57, 58.

In order to disengage the filledshuttle from the upturned ends 58 of the fingers 57 so that the fingers will'not pull the filled shuttle out of the shuttle box after having deposited it there, the fingers are arranged so that their tips traverse'an are lower than that traversed by the shuttle-supporting surface of the lay; (See Fig. 5). In this connection it is necessary to raise the filled shuttle relatively to the fingers 57 in order to enable the filled shuttle to go into the shuttle box. vided with a pair of fingers 76 which project toward the front of the loom, as shown by Fi s. 4 and 7. The upper surfaces of these fingers are inclined relatively to the shuttle-supporting surface of the lay, and

are arranged to intersect the arc traversed by the rear bottom edge of the shuttle. It.

follows, therefore, that the shuttle will rideupon the fingers 76 and will thus" be lifted out of engagement with the tips 58 of the fingers 57, and during the remainder of the movement of the carrier toward thelaythe For this reason the lay is 'profilled shuttle will be supported by the lay althou h still receiving lateral movement from t e carrier The carrier has aninterval of dwell in the position shown by Fig. 5, during which the receiver 35 descends to deposit the spent shuttle .7: upon the surface 56. Ashereinbefore stated, it is necessary to depress the clamping device 60 in order toseat the spent shuttle upon the surface 56. Such seating of the shuttle is insured by one or more shuttle-engaging portions 77 on the. shuttlebox front 13. (See Fig. 5). When the receiver 35 descends, the lower front, edge of the shuttle settles into the angle formed by the surface 56 and ears 67, but the lower rear edge of the shuttle is caught by the cars 68 of the clamping device. The cam 22 is timed to cause the shuttle-box front to de-- scend during the carriers interval of dwell in the position shown by Fig. 5, and during the descent of the shuttle-box front the portlon or portions 77 engage the upper rear edge of the spent shuttle and bear downwardly thereon with suflicient force to depress the member 60 and seat the-shuttle on the surface 56. As the member 13 continues to descend, it-engages the ears 68 and further depresses the member 60 against the stress of the spring 62 but as soon as the ears 68 have been disengaged from the member 13 in consequence of return movement of the carrier, the member 60 rises in response to its spring 62 until its movement is arrested by clamping action on the shuttle.

Before the shuttle carrier reaches its extreme forward position the front side of the v spent shuttle thereon engages the front wall v '80 and 81 is to operate the loader 82,--Which kn 10' of the shuttle support 10, and the shuttle is thereby arrested. The clamping device 60, however, continues to move with the carrier and isdeflected downwardly by the shuttle so that the ears 68 pass under the shuttle before the device is returned to its normal position as shown by Fig. 9.

After the spent shuttle has been deposited upon the support 10, but before the change shaft 23 hascompleted one revolution a dagger (Fig. 1) is raised so that its rear end will register with a striker 81 carried by the lay. The function of the members transfers a 'full bobbin from the magazine 83 tothe shuttle w. The forward end of the dagger 80 is connected by a pivot member 84 to an arm 85. This arm is arranged to swing upon a pivot rod 86, and it has suitable connection with the loader 82 which is likewise pivoted upon said rod. As shown by Fig. 1, the member 80 rests upon the upper end of a rod 87. This rod is carried by a member '88 whose lower end is connected by pivot member .89 with a cam lever 90. This lever has a toe 91 which rests upon a is mounted upon the fulcrum member 20 hereinbefore mentioned. As the lever is raised by the action of the cam 92 the member 88 rises and such motion is transmitted to the rod 87 by a cushioning spring 93, the latter being adapted to observe the movement of the member 88 in case the striker 81 should overhang the free end of the dagger 80 so as to prematurely arrest upward movement of the latter.v

The dagger 80 is provided with a pin or other projection 94 against which a latching device 95 bears. This latching device is mounted upon a pivot stud 96 and has a weight portion 97 by which the member 95 is automatically moved under the projection 94 when the latter has risen to its highest position. The dagger 80 isthus latched in re ister with the striker 81, althou h the rod 8 is permitted to descend imme iately by its lifting cam 92. The dagger 80 remains-in register with the striker 81 until the lay has gone forward and part way to the rear after theinterchange of shuttles. As the dagger 80 is carried forward by the striker 81 it transmits the necessary motion to the arm 85 to cause the loader 82 to descend, and, at the same time, the projection 94 on the dagger is carried beyond the latching device 95 so that the dagger is no longer supported by the latching device but is supported exclusively by its pivot member 84 and by the striker 81. As the striker moves to .the rear after having caused the operation of the loader 82, it releases the rear end of the dagger 80, and the latter then drops, the projection 94 at such time being in front of the latching device 95.

The stopping of the change shaft 23 and the restarting of the weaving mechanism is has completed one revolution. The mechanism for those purposes includes a starting shaft 100, an arm 101 aflixed thereto, a rod 102 pivotally connected at .103 to the arm 101, a collar 104 aflixed to said rod, an operating lever 105 mounted upon fulcrum member 20, and a starting cam (not shown) on the shaft 231 The elements just recited are all well known and operate in the well own manner, and no further description of them will be necessary.
