FILLING-CARRIER FOR wnr'r-nnrnnnismne Looms.

Patented Sept.- 14, 1909.

Application filed October 10, 1 908. SeriaI No. 457,118.

To all whom it mdy concern; Be 1t known that we, JoHN R. FITTON and Cris-units H. BERGLUND, a citizen of the in Filling-Carriers. for \Vett-Replenishing Looms, of which the following is a specification.

' Our invention relates to a filling carrier or shuttle for weft. replenishing looms, in which a new filling carrier or bobbin is automatic ally inserted when the filling carrier-or bobbin in the running shuttle is substantially or practically exhausted, and our invention more particularly relates to a. self-tl reading shuttle, having an automatic'filling thread cutting mechanism combined therewith, of the type shown and described in the Letters l atent of the United States, No. 914,703.

The object of our ,invention is to improve upon and simplify the construction of the self-threading cutting mechanism shown and described in said Letters Patent, and also to. provide an improved selftl1rea-ding mechan ism for the shuttlef In the self-threading shuttle shown and described in said'Letters Patent, a filling carrier or bobbin, having first wound thereon a few winds of filling in one direction, and the re maining winds of filling in the reverse dimotion, is used. li -hen new filling is inserted in the shuttle from the weft replenishi ing mechanism, the filling is automatically threaded into the eye of'the shuttle by the threading mechanism, and as't'he filling is drawn off from the bobbin, it is carried by 1 its circular nwrement into. a guide, and remains in said guide until the fillin .on the bcibbin, of the ordinary wind, has" een en- 5 tirely draw-n off from the bobbin, and the? filling of the reverse wind is reached; the-n by reason-of thereverse wind of the filling, the filling is caused. to have a circular movement in an opposite direction, and passes out 1 of the guide referred to. and into another guide or eye in a position to be engaged by the cutting mechanism to be out at the next operation of said cuttingmechanism, al lfias fully described in said Letters Patent.

In our improvements, we do away w-itlr the funnel-shaped guide, shown and de scribed in said patent, for the filling, and" ordinary wind. an upward direction, and is provided with substitute therefor a' double, or looped wire, over which the filling thread freely passes, as long as the filling on the bobbin has the An arm or lever extends in an eye at its upper end, from which a slightly curved slot extends downward y, which slot open at its lower end, and adapted to have the filling pass into it, when the filling, wound in the ordinary way, has been entirely drawn oil from the bobbin, and the filling having the reverse wind, is reached.

Our self-threading mechanism, which we hate combined with. our present improve ments in filling cutting mechanism, is of very sii'nple construction, and consists of a suitably shaped metal plate, having a horn or hook on one end, and a downwardly extending portion, adapted to guide'thefilling,

and to hold it in the thread. eye.

'We have only shown in thedrawing a detached portion of a shuttle with our iml proveinen-ts combined therewith, sufiicient to enable those skilled in the art to understand the construction and operation thereof.

Referring to the drawing':Figure l is a plan View of one end of a shuttle, and our improvements in thread cutting mechai'iisin, and a self-threading mechanism, attached thereto; the fillin is shown as it is drawn otl' from the bobbin in the usual or normal direction. Fig. 2 corresponds to Fig. 1, but

shows the self-threading mechanism removed, and the filling thread drawn oft from the bobbin in the reverse direction, to be cut by the cutting mechanism.

Fig. '6 is a front side View of the stilt-threading mechanism,

Fig. 7 an end view of the selfthread in-gmechanism shown in Fig. 6, look-- ing in the direction of arrow 0, same figure. in the accon'ipanyin-g drawing, 1 is a portion of the shuttle body, 2 is a bobbin, and 3 filling thereon. A block AL is suitably secured in a recessed portion of the'back wall of tire shuttle, and is. in this instance similar to the block shown and described in said with a, filling thread eye 6'.

.up and "4 has on .its upper end a cam-shaped plate Letters Patent, No. 91et,703. The block l has in thisinstan ce two :inwardly vertically extendlng progections'i, one of which is provid d on its upper edge witha cutting sur- 'lac 1".". Extending through the lower part ot. the pro ections l 1s a pin 5, on which lower end, and adapted to receive the filling 3 on llS circular movement upwardly and.

toward the cutting lever, as shown in Fig. 2, when the filling is unwound from the bobbin in a reverse direction from the ordinary wind. The lever 6 has a rearwardly extending arm 6 which extends through ,an openii'ig 7 in a bolt 7,wl1ich,extends loosely in an. opening in the block l, tohave a vertical down movement therein. The bolt or head 7", which isadapted to be engaged and'operated by a trip, not 'shown, suitabl'y located on the hand-rail of the loom, or, the

head 7" shuttle box, not shown. A helically coiled expansion spring. 8, extends between the onthe bolt 7, and, the upper part of the bearing in the plate t for the bolt 7, and

acts to-yieldin-gly move up the bolt 7 and the arm 6" on' the lever 6, to hold said lever lll'ltS inoperative position, as shown in. Fig.

4:. The engagement of theend of the arm- 6" of the lever 6, with the upper part of the.

transverse opening through the block 4,

limits the upward movement of the bolt 7, see Fig. l.

, Extending out from the two projections 4 on the block 4:, and in this instance attached thereto, is a double wired}, preferably of loop shape, which forms aguide for the filling 3,

which loosely passes over said wire as long asthe filling is unwound from the bobbin 111 the ordlnary (llI'BCt-IOH, as shown in Fig. 1.

\Ve will now describe our improvements.

in the self-threading mechanism shown in the drawing.- The self-threading mechanism consists in this instance of a' top plate 10, preferably made of sheet metal, which jection 10.

extends upon the upper side of the shuttle, as shown in Fig. 1, and has extending downwardly therefrom in a vertical plane and at right angles thereto, and preferably riveted thereto, a second plate or projection .10, see Fig. 5, which extends in a recess 1" in the shuttle 1, and is secured therein, in this instance by a screw 11 extending through an opening 10 in the pro- The inner edge of the plate 10 is preferably made of curved shape, as shown in Fig. 1. and at the outer end of said place of'the practical plate is a horn or hook 16, around which,

the thread passes, and is guided along the inclined e'dge-' 10 on the projection 10",

see Fig. 6, and through the curved thread slot 1 ii: the side of the shuttle l, 'and into 'theopen ye 10 in the projection 10",.and

into the thread eye 1- in the shuttle. The vertically extending plate or projection 10' on the plate 10 has secured thereto, or made integral therewith, a side plate 10 which extends inwardly into the opening in the body plate or projection 10 is preferably of the shape shown in Fig.7, and has on its edge,

near its upper end a notch or undercut p0r-' U011 10", which acts to hold the filling in the proper position as it is being threaded into the shuttle.

7 From' the above description in connection with'the drawing, the operation of our im provementswill be' readily understood by those skilled in the art. 7 f The filling carrier or bobbin to be used in our improved self threading shuttle, as stated above, has the filling wound thereon of the shuttle,- preferably. .at right angles to the plate 10, see Fig. 4, The side.

tion, as a'right hand wind, until the bobbin is fully wound. As the fillingla'stwound on the bobbin is drawn off from the bobbin,

asthe shuttle is thrown through the shed,

it will have a circular movement, and when a full bobbin is' transferred from the magazine into the running y or substantially exhaustedbobbin i the shuttle, the. end of the filling on the bob in being attached to a sta azine, the filling. is. drawn into the threading mechanism, and.

tionary part of the ma automatically threaded into the jshuttle',as the shuttle is thrown across the lay from the magazine end thereof. The unwinding-of -the filling-from the bobbin,- as-the shuttle is operated, communicates to'the fillinga circular "movement. away? from the cutting -n1echanism,asshown in Fig. 1,,and the loop wire v9 acts as support for the filling.

at a predetermined time, the cutter lever 6 will be moved toward the rear side of the shuttle, to carry the filling against the cutting edge at on one of the projecv block 4, 'and clit the filling,
