The' invention herein to be described relates to looms, Yand more particularly to looms of the filling replenisliing type, wherein a fresh supply of filling is ai'itomatieally provided when that in use fails from any cause to be laid in the shed.`

As well known by those skilled in the art the filling may fail to be laid in the shed for various reasons, as, for instance, when the filling carrier or shuttle becomes exhausted, or when the filling breaks. Under such conditions -it is desirable that a fresh charge of4 filling be automatically supplied to t-h'e weaving instrumentalities.

The aims and purposes of the present invention are to provide means which will he simplein construction 'and efficient in operation, whereby, upon failure of filling'froni 'any cause, a fresh supply of filling may be delivered to the weaving elements. all as willbest be made clear from the following description and accompanying drawings of oneforin. or character of such means, it heing understood. that the invention is not restricted to the particular construction shown anddeserihed. but in its true scope is definitcly set forth hy the clai'ms.

In the drawings z-FigureLl is a front ele- 40 Vation of one side portion of a loon'i sufficient to show the features of the present in Yvention and their relation with adjacent parts; Fig. 2 is a section on the liiie`Q--2, Fig. Llooking in the direction of the arrow fr; Fig. 3 is i. section on the line 2M?, Fig. l,

looking in the direction of the arrow l); Fig. is a detail sectional view on the line 4--L, Fig. 3; Fig. 5 is a detail sectional view on the. line Vin-fi, Fig. 3, showing one fornil of. the swinging gate and its supporting and controlling elements.; Fig. (3 is a section on the line (l-Ji, Fig. 2; and Fig.7 is ase-ction on the line 7 7, Fig. 2.

The loom frame 1,Which may loe of 'any usual or desired character, is provided with a Isuitable support for features of the repleiiishing mechanism, said support, in the present form of the invention, comprising a bracket 2 secured hy bolts 3, 3 to the loom frame, and haring rising therefrom a ffange or plate i, constituting a sustaining means for the hopper The hopper 5, which contains the filling carriers to be transferred to the shuttle, nmay-he, in part at least, of thegeneral character of that set forth in application Ser. No. 501,452, lfiled June l1, 1909; that is to say, it is or may be formed with its front and back walls made flaring so as to accommodate filling carriers in staggered relation, as indicated iii Fig. 2, and for vthe purpose fullyannounced in said prior application, a suitable slot 6 being provided for the passage of the filling ends from the carriers within the hopper toa suitable holding means for the filling ends outside the saine. As the filling carriers progressively more downward in the hopper they arrange themselves inisingle fileforination, substantially as described in said prior application and as shown iii Figs. 2 and 3 of the present drawings, and are successively and singly ,Q 'iren a vposition at the discharge throat of the hopper for transfer to the shuttle as occasion demands. f

The discharge throat for the li-.rge or head end of the filling carriers, which for identitication may be designated the head throat, is provided with a tiXed guiding hack Wall T leading downward and in such position as to guide thehead end'of the carrier properly into the shuttle when the shuttle is posi tioned beneath the throat. trontwall of the head throat is formed so that when .the loom is ruiming under non mal condition a filling carrier cannot pass through the throat. but when a filling carrier is to he transferred to the shuttle to replace a carrier therein, the filling o n which has failed from any cause, the filling carrier then in transferring position in the hopper may pass through the throat, as will now be more fully explained.

Mounted on a ledge 8 secured to the bracket 2 and preferably'formed as a pro- 'jeetion on the plate 4, is a. slide S) having a I flange l() constituting the front wall of the throat 1l, said slide being normally under the influence of a spring 12, one end of which Patented oet. is, 191e.

The opposite or is seated against a lug 13 of the slide, and .bunter 28, as indicated in Fig.- 2, thus acthe other end of Which bears'against a cor-y tuatingthe transferrer. The filling detectrespcnding lug 14 projecting from the plate ing mechanism may be of -anyusual or Well 4, thev construction being such that the known type, and', being familiar to` those 5 'spring 12 tends trrinove the slide to the skilled in the art, is-notherein shown, it 719 right, Fig. 2.

due to the operation of thc transferring mechanism, the slide 9 becomes released or unlocked so that the downward movement of the fillingl carrier- 19 under the action of the transferrer is enabled to move the slide 9 and consequently the frontwall of the throat a distance sutlicient to permit the tilling carrier to pass through the throat, as will be readily understood. Thus it will be seen that the head throat for the passage of the filling carrier-has a fixed back wall and a front wall which is fixed and immovable during the normal operation of the loom. but which is unlocked and free to be moved when a filling carrier is to be transferred 'from the hopper to the shuttle.

For supporting and guiding the tip porltions of the filling carriers, the hopper 5y is provided With the ledge 48, Fig. 3, which extends in la downward direction and at its yterminal portion forms the rear fixed Wall 49 of the throat through whichthe tip end portion of the carrier passes as it is transerred tothe shuttle,- and which, for identi?. Iication, may be denominated the tip throat, in contra'distinction to the head throat prex viously herein described.

The front wall oi the tip throat is formed as a tip stop and guide surface, which is so constructed that, when the loom in normal workii'ig condition, .it forms a stop to ylimit forward or downward movement of the iilling carrier at the time being'in position for transfer, and so far closes the tip throat'that the tip of the carrier cannot pass therethrough; but which, when a. car,-

rier isto be transferred, ismoved to constitute a front guide to direct/the tip of the carrier' to properA position into the shuttle chamber and to open the throat for the passage of the carrier tip, one form of which feature of the invention will now be described.' t

Loosely mounted to turn on the rod 22 near the end portion thereof is an arm 50 l'iaving at its'free extremity a head 5l provided with a tipengaging and guiding sur- At its lower portion the surface 52 is curved to lt'orm a. shoulder or support 53 extending toward the iiXed Wall 49 of the .tip throat, the construction being such that when the head 51 is sustained in the` position indicated by full lines, Fig. 3the tip oi the filling carrier cannot pass between thefixcd back wall 49 and the shoulder 53, but when the arm o() isperinittcd -to move dmvnward, as will presently appear, the tip of the carrier is freed to its passage through the throat.

Projecting laterally from the head 51 is a lug 54, Figs. 4 and 6. adapted to rest on a projection 55 secured tothe member 40 of thc transferrer, the construction being such that when the transferrer is in up or normal position, the projection 55 will supi port the Vhead 51 in the full line/ position, Fifr. doiinwardto transfer a filling carrier to the shuttle, the arm 50 and head 5l will be permitted to fall until the foot 56 of the head rests upon thetop of the shuttle boX, which is then beneath the throat with the shuttle in position to permit a change of filling car# ricrs, as indicated in Fig. 3. Thus it will be apparent that while the surface 52 of the head forms a stop for the tip end of the filling carrier when in position for transfer, it likewise acts as a guide to direct the tip ont' the filling carrier properly into the shuttle chamber, as the carrier is being transfcrred. said surface at suchl time preferably extending to the top of the shuttle box, and the-foot 56 resting thereon. Obviously the details of the tip stop and guiding head may be variously changed within the true scope of the present invention, which, so Jfar as ap-y plicant icnowsis the first instance in the art where the front guide wall of the tip throat has been made to act as astop or support for the tip of a carrier when in transferring position and a front tip guide extending to the '3, but when the. transferrer moves.

shuttle chamber or'top' of the shuttlebox to.

guide the carrier during transfer.

As a means for limiting the extent of upward movement of the head 51, a Stop 57 may be provided on the plate or supporting bracket 4X of the hopper; and the member 40'of the transferrer may be provided with an overhang 58, Fig. 4, to confine the head 51 to proper working relation with said member.

In order to provide a rear guide for the tip oi"y the carrier, the bracket or plate 4X has pivotally connected therewith the yielding finger 59, Figs. 3, 4, 5 and G, the shank G0 of which passes to the outside of the bracket and is provided with a spring (Si norinally acting7 as in Figs. 5 and 6, to hold the iinger 59 -in position extending acrossl the tip throat. said spring being` yieldahle so that when the filling carrier is moved downward by the transferrer, the finger 50 will turn downward to the top of the shuttle, though preferably ,not into the shuttle chamber, as indicated'in Fig. 3, and provide a rear guide for the carrier tip.

.From the construction shown and described as one form ot' means for carrying the invention into practicalfefiect. itfwill be seen that the tral'is'terrer is provided with portionsfor engaging the carrier at or adjacent the head and at or near the smaller end or tip of the carrier; and that. these cngaging' portions haveupwardly extending .surfaces or faces which `act as stops to the i'lownward movement of the other carriers in the hopper when the end carricris being transterref, said surfaces or faces lifting after the transfer to permit the next filling carrier to move to transferring position. yIt

65 pivotalliyl is desirable that this movement of the next filling carrier '.to transferring .position be positive and well defined, and that not only the base or heavy' portion be-moved t'o posi- 'tion but the ti be also definitely locateda"s indicated in-tliedrawings To theseends the following is one form of the means embraced by this feature of the invention. r Mounted on a suitable supporting stud 62, Figs. l, 2; 6 and 7, preferably projecting from a bracket or lug 63 sustained by the front wall of the hopper or carried 'by the hopper-supporting bracket, is a filling earrierpositioner and separator. In the present form of the invention this comprises .a lever, one arm 64 of which carries a yielding nger mounted on said arm 64: at 66,

and norma y under the influenceof a spring 67 tending to straighten said finger' or move it into prolongation with the arm 64,' as clearly indicated in Fig. 2. Suitable stops 68 andl 69 on the arm and fingerrespectively limit the. movement of the linger in the direction stated, but permit it'to'move in op'- position` to the-spring tension. The other arm 70 of said lever extends under a pin or lug 71 carried bythe tiansferrer arm 37, and

' as ring- 72 surrounding the stud 62 has one Y en 73 Veld` by a Xed/ part or lug 75 and its 3-0 spring. normal y acting to turn the lever c o ckwise, viewing. Fig. 2,

The filling-carrier ositioner or lever is preferabl so disclose ,with relation to itsv associate parts thatthe finger 65 ma* engage afilling carrier between the hea and tip portions thereof.l

' .From the constmiction described it will be a parent thatupon downward movement of Y pleiiishment, the pin o'r lug 7l will engage i i the arm 70 of the carrier positioner and turn it .contra clockwise, Fig.' 2, the finger A65 at sch ltime riding over thelling on thecar .rier-v above that being transferred *until on complete depression 'of the transferrer and` consequentcompletion of transfer the Said Enfer attains the 'position indicated by doti te lines, Fig. 2. As the-transferrer rises after the transfer, the s'plring1 72 acts upon the psitioner, causin t e gage the lowermost fil in carrie-r in t-he hop- '.per and move it into ansferring position, the transferrer at such time having Ioved to upper or substantially normal .position'.

. It will' be 'noted that the 'filling'lcarrier 'positionei not .only moves the next carrier to be transferred intdtransferri position, b ut by engaging between the engi portions 'of the carrier and between the head and vtip throats it insures that both ends ofthe car- -rierwill be brought into proper relation with the front walls ofthe throats, each of which will act, as a fixed fulcrum about which the carrier will move under the force other endl enga ed beneatlrthe arm 70,i said 'transferring movement.
