- reams-Famine MECHANESM FOR LOQMS.

Patented May 1, 1906.

which the following description, in connec- "tion with the accompanying drawings, 1s a specification, like characters on the drawings representing like parts.

k This invention relates more particularly to so-ealled feeler-looms provided with auto matic mechanism for replenishing the runnin fillingp'rior to complete exhaustion thereo In such looms the end of the old fillingextends "from the cioth :70 the sliuttle contain ing the filling-supply to be abandoned at the time filling change is to be effected.

'and t --Means have been devised to art or sever such thread adjacent shutt e and there afterto art it adjacent the edge of the-cloth, andiin nited States Patent to Draper, No. 683,423, dated September 24, 1901 mechanism is shown for not only so parting the thread, but also to catch or hold the severed piece and prevent it from being woven into the cloth.

The parting adjacent the cloth is effected by a thread-cutting temple, and the thread is clamped and arted adjacent the shuttle by separate mechanism, after which the latter is moved toward the cloth to slightly slacken the clamped end of thread as it is brought into ran e of the thread-cutting templc to avoid breifiiing the thread.

My present invention isI-in some of its general features ver similar to the structure shown and described inthe patent referred to; but I have devised improved means for more securely and eiiectuall y clamping the thread, so that there can be no tendency for it to 1pull out from the clamp prematurely,

ereby I insure the parting by the temple thread-cutter and prevent any liability of the filling end being woven ito the selvage of the cloth.

' The novel features of my invention will be fully described in thesubjoined specification and particularly pointed out in the following claims( I have shown my invention as applied to a loom wherein the running-shuttle 18 provided automatically with a fresh supply of fillin at the proper time; but it will be manifest t at it is equally applicable to a loom provided with shuttle-changing mechanism.

Figure 1 is a transverse sectional view of a portion 'of a loom provided with automatic filling-replenishing mechanism, showing a portion of such mechanism, one embodiment of my invention being illustrated in connection therewith and in normal inoperative position. Fi 2 is a top plan View of a portion of the mec anism shown in Fig. 1 confined principally to the parting and clamping devices. Flg. 3 is an inner side view, enlarged, of the thread-parter and thread-clamp after the thread has been clamped and arted. Fig. 4 is a top plan view thereof; an Fig. 5 is a transverse section on the line 5-5, Fig. 3,

looking toward the right and showing clearly the manner in which the thread is'clamped.

As in the patent referred to, the parter and clamp are herein shown so constructed and arranged that the will be in position to act being mounted separate y and being stationary as a whole.

Referring to Fig. 1, the lay A the feeder F to hold the filling supplies or carriers b, the transferrer f, fulcrumed at f, the controlling rock-shaft d, turned in the direction of arrow when the replenishing mechanism is to be operated, the notched dogm operatively connected with the depending end of the transferrer, and the bunter C on the lay to at times cooperate with the dog may be and are all as in said patent. So, too, the shuttle-feelerrY, having its hub y, Fig. 2, mounted on the stud a to rock thereon and also tornove laterally thereon, (the means to effect such lateral movement forming no part of my invention,) the stud 1 on the shuttle upon the filling w en the shuttle is properly,

feeler Y, having an attached finger n to control'the rotative movement of the dog m on its support, the arm (2", fast on rock-shaft d V mal inoperative position, as illustrated in j 15, interposed between the head of the screwt v .M.

Fig. 1, may be and are as in the patent hereinbefore referred to.

The upper extremity of the feeler Y notched at 1, Figs. 1 and 3, to receive the tilling-thread when the feeler is moved into operative position adjacent the mouth of the replenishing shuttle-box B Fig. l, and a fixed cutting-blade 2 is secured to the feelcr at the lower edge of the notch 1.

On the headed screw-stud 3as a fulcrum is mounted the member 4, which is at once a cutting-blade and a clamping-jaw, its lower edge 5 cooperating with the blade 2 to part the filling-thread at the proper time, (see Fig. 5,) said member 4'resting against the flat face of the 'feeler and having at its front end a depending heel 6, Fig. 3.

A fixed or stationary member 7 of the thread-clamp is arranged to cooperate with the adjacent face of the combined blade and clamp member or jaw t, the member 7 having a notched end 8 adjacent the feeler-notch 1, but with its lower edge 9 above the upper edge of the fixed blade 2. This tixed member 7 is held in place by the screw-stud 3 and by a pin it), fixed in the fecler and passed through the member 7, the pin extending loosely through a slot 1 l in the movable member 4. (See dotted ines Fig. 3.)

By reference to Fig. 4 it will be seen that the member4 iscut away or reduced in thickness at 12 to accommodate the lixed member or jaw 7 of the tlnead-clamp. Adjacentthe outer face of the member 7 .l have provided a second clamping member .15 fulcrumed on the screw-stud 3 and lixedly.attached, as by rivets H, to the thick ftnward end of the member 4 to move in unison therewith and so placed. that it moves up and down against the contiguous face of the lixed clamping-jaw 7. The member 13 is also slotted to correspond with the slot 11 for the pin i(),and in Figs. 4 and 5 the relativepositions of the. members 4, 7, and 13 are clearlyshown. A spring-washer stud 3 and the adjacent face of the member 13 of the thread-clamp, holds the said member yieldingly pressed against the fixed jaw 7 and presses the latter against the blade-jaw 4., in turn holding the latter against the inner face of the feeler. A tlllttl(l-[')ztli.0l eomprising the fixed blade 2 and the movable blade 4, is thus provided with a double-acting threadclamp comprising the movable jaws 4 and I3 and the interposed fixed jaw 7, both parter and clamp being mounted on the shuttlcfeeler, the member 4 being common to both parter and clamp and constituting a bladcaw. When. the partcr and clamp are in po- 'sition to act upon the lilling-t bread, as will be the case when thc lay has completed its forl ward movement, then the filling-thread will l enter the fceler-notch l and the notch 8 of l the stationary clamp-jaw 7, the bladc-ja'w l and jaw 13 then being open. 'lhercaftcr l when the members 4 and 13 are closed they lirst act upon the thread i, Fig. 5, pressing it down over the lower edge 0 of the notch 2s and at each side of the jaw T, clamping it tightly between the faces thereof and the adjacent faces of members 4 and 13%, and as the said members continue to descend aftcr the thread has been so clamped its edge 5 will cooperate with the lixed cutting-bhule 2, part ing the thread.

In Fig. 5 the thread t is shown as clamped and also severed or parted. By the doubleacting clamp thus described the thread is held tightly with absolute certainty, with no opportunity for it to slip or draw through the clamping members, insuring its movement into the field of action of the thread-cutting temple T, Fig. 2,when the feeler Y returns to normal position.

The setting or opening of the parting and clamping devices is ell'ected by cot'iperation of the pin 16 Witha part of the-threatl-cntcher substantially as in the patent to which I have previously referred, and as such operation is fully described therein it needs no explanation herein.

When the clamp and parter are bodily moved into operative position, the blade-jaw 4 and jaw 13 are open and the heel 6 is in the path of a portion of the lay to be struck as the lay completes its forward beat to thereby rock the blade-jaw and jaw 13 on their t'ulcrum 3 from the relative position shown in Fig. 1 to that shown in Fig. 4, successively clam wing and parting the thread 1 adjacent the shuttle.

The lay is shown in Fig. l as cut away (see dotted lines) to leave a shoulder 17 in the path of and to act upon the heel 6 to close the movable members of the parter and clamp at the proper time.

As the return movement of the shuttlefeeler Y takes place the parted and still clamped thread is brought into engagement with the thread-catcher C before the clamp is opened, so that when the temple thrcanl-cutter operates to part the thread adjacent the cloth the severed piece of thread will be held by the thread-catcher in a wclll nown manner.

Rocking of the shaft d in the direction of arrow 50, Fig. 1, positions the dog m in the path of the hunter and also permits the operative positioning of the shuttle-fcclcr, so

that. if the shuttle is properly boxed the ihrcad-partcr and thread-clamp will be positioned to act upon the thread, as has been de scribed.

It the shuttle is improperly boxed, the lcclcr will not move far enough to bring the parter and clamp into operative position, and as the tilling-rcplcnishing mechanism will not operate at such time the described operation of the thread clamp and parter will not be efl'ccted.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is I a In an automatic filling-replenishing loom, a thread-parter and a thread-clamp, each comprising a movable and a relatively fixed member, to act upon the thread of the filling-supply to be abandoned, the fixed member of the clamp cooperating with both .10 movable members to securely clamp the thread, and means to actuate the movable members to successively clamp and part the thread upon replenishment of filling.

2. In an automatic filling-replenishing loom, a thread-parter and a thread-clamp, each comprising a movable and a relatively fixed member, to act upon the thread of the filling-supply to be abandoned, the fixed member of the clamp cooperating with both movable members to securely clamp the thread, a connection between the movable members, and means acting through such connection to operate the movable members in unison to successively clamp and part the 2 5 thread upon filling-replenishment.

3. In an automatic filling -'repi':nishing loom, a threadparter and a thread-clamp, each comprising a movable and a relatively fixed member, bodily movable upon replen- -3o ishment of filling into position to act upon the thread of the filling-supply to be abandoned, the fixed member of the clamp being interj posed between the said two movable'mem-' bers and cooperating therewith to clamp the 5 thread, and means to actuate the movable members in unison to clamp and partthe thread upon replenishment of filling.

4. In an automatic filling-replenishing loom, a thread-parter and a thread-clamp,

40 arranged in juxtaposition and adapted to act .upon the thread of the filling-supply to be abandoned, a movable combined partingblade and clamp member, forming one element of'tlle parter and clamp, a second clamp member movable with said first-named member, means to operativcly move said. men'ibers upon replenishment of filling, and a relatively fixed member of the clamp, with which both movable members cooperate to doubly clamp the thread.

5. In an automatic filling-replenishi'ng l loom, a thread-parter and a thread-clamp, arranged in juxtaposition and adapted to act upon the thread of the filling-supply to be abandoned, the parter including a fixed blade and the clamp a fixed member, a movable combined parting-blade and clamp member movable between and adapted to co ,operate with both of said fixed members, a

second movable clamping member cooperat- 6c ing with the fixed member of the clamp and connected with the combined parting-blade and clamp member, andmeans to move the latter and the second clamping member in unison, to clamp the thread at each side of the fixed member of the clamp and then part the thread.

6. In an automatic filling-replenishing loom, a thread-parter and a thread-clamp, bodily movable upon replenishment of filling into position to act upon the thread'of the filling-supply to be abandoned, the parter in cluding a fixed blade and the clamp including a parallel fixed jaw, a combined blade and jaw movable between said fixed members; 5 and cooperating with each, a jaw fixedly connected with the combined blade and jaw and cooperating with the outer face of the fixed of the clamp, and means to yieldingly press the fixed and movable members laterally against each other when actuated upon replenishment of filling, and means to effect actuation of the movable members in unison.

' 7. In an automatic filling-repleniShing loom, a shuttle to contain a supply of filling, a shuttle-feeler, movable into operative position prior to filling change, means mounted on the feeler to act upon the thread of the filling-supply to be abandoned, said means including a fixed blade and a fixed jaw, two connected, movable members one of which cooperates only with the said jaw and the other with both the j aw and the fixed blade, whereby the thread is doubly clamped before itis parted, and means to operate the movable 9 5' members to clamp and then part the thread when the shuttle-feeler is operatively positioned.

In testimony whereof I have signed my name to this specification in the presence of 10 two subscribing witnesses.
