FlLLlNG -FREPLENISPHNG LOOllllln SPECIFICATION forming part of Letters Patent No. 789,287, dated May 9, 1905.

Application filed January 9, 1905. $erial No. 240,159.

Be it known that I, ALI'DA M. MARooUx, a citizen of the United States, and a residentof Hopedale, county of \Vorcester, State of M assachusetts, have invented an Improvement in Automatic Filling-Replenishing Looms, of which the following descri )tion, in connec tion with the accompal'lying drawings, is a specification, like characters on the drawings representing like parts.

in automatic looms of the Northrop type such, for instance, as in United States Patent No 5Q9,9 t0--the filling-thread extends from the filling-feeder to the nearer edge of the cloth on the lirst shot of the shuttle after [illing replenishment, and its severance has heretofore been eflected by a temple tl'n'ead-cutter near the selvage, several picks usually intervening before the filling end (as it is termed) is severed. W'ith the addition to such looms of double-fork mechanism, whereby filling failure is detected on the pick in which such failure occurs, a practical difliculty was met, due to the delay in severing the filling end, as the latter would act upon the adjacent filling-fork and tilt it at each forward beat of the lay whether or not the running lilling be intact. Thus the duty of detecting failure of the filling devolved wholly upon the other filling detector or fork, and if failure occurred on the shot of the shuttle toward the replenishing side of the loom delay in replenishing occurred, with the formation of a thin place in the cloth.

.ln United States Patent No. 711,736 means were provided to insure the proper cooperationof the auxiliary fork with the running lilling entirely irrespective of the presence or absence of the filling end. For this purpose the auxiliary fork Was moved into position behind the lilling end presented by the operation of the replenisl'ling mechanism to cooperate only with the running lilling. The time of severance of the filling end was there by rendered immaterial so far as the auxiliary fork was concerned.

In my present invention, which relates to a loom provided with automatic filling-replenl l l ishing mechanism and with double-fork mechanism, I have provided means controlled directly by one of thefilling-forks to effect severance of the lilling end promptly and positively after the lirst pick upon which fresh filling has been laid and before the presence of the filling end can interfere with the proper operation of the auxiliary fork. The mechanism has been simplified. The auxiliary fork is relieved of any abnormal action or move ment, and the filling end is severed quickly and surely.

The various novel features of my invention will be fully descril. ed in the subjoined specification and particularly pointed out in the following claims.

Figure 1 is a top or plan view, centrally broken out, of a double-fork loom provided with automatic lilling-replenishing mechanism and having one embodiment of my present invention applied thereto, the parts being in normal running condition. Fig. 2 is an enlarged transverse sectional detail on the line 2 2, Fig. 1, looking toward the left, showing the auxiliary detector or fork and the lillingend severing means controlled thereby in normal position. Fig. 3 is a similar detail. but with the severing means in position ready to act upon the lilling end as the auxiliary-fork slide returns to normal position after having detected lilling failure. Fig. 4C is an opposite side view of the auxiliary fork and a portion of its slide and showing more clearly the connection between it and the tilling-end-severing means, and Fig. 5 is a detail in side elevation of the movablemember of the severing means to be referred to.

I have herein shown the double-fork mechanism as substantially of the structure illustrated in United States Patent No. 7210M, and, referring to Fig. 1, the main filling detector or fork f, its slidef the fixed stand f, in which said slide is mounted, and the arm (Z, fixedly secured to the controlling rockshaft (55, being all as in said patent and located at the left-hand side of the loom. So, too,

the auxiliary detector or fork (/q its slide and stand 1, located at the right-hand or replenishingside of theloom, are arranged as in Patent No. 727,014, the arm (Z cooperating with the outer end of the slide g having a slight lost-motion connection with the rockshaft cl. Outward movement of the slide acts to arrest take-up, as in the patent referred to, but does not turn the rock-shaft (Z far enough to effect the operation of the replenishing mechanism, the latter comprising a transferrer f and a feeder F to contain a supply of filling-carriers b, of wellknown construction.

The main detector or fork f is herein shown as adapted to directly efiect the operation of the filling-replenishing mechanism, and by or through the dog 6 slide-bar e, pivotally connected with the arm (Z, and the shoulder 8 of the hook w, carried by the main actuator or weft-hammer, (not shown,) the operation of said replenishing mechanism is effected indirectly by or through the action of the auxiliary detector g upon detection of filling failure, all as in said Patent No. 727,014.

The lay A having the usual shuttle-boxes thereon, one of which is indicated at B, Fig. 1, the automatically self-threading shuttle 5*, the breast-beam A the holding-plate N for the shipper S, and the knock-off arm a may be and are all of well-known construction.

Adjacent the standsf and and at their inner sides I have shown temples T and T, respectively, (see Fig. 1,) mounted on the breast-beam in usual manner, the temple T being of usual construction, while the temple T at the replenishing side of the loom is tech nically known as a thread-cutting temple, it being provided with means to sever the filling end which extends from the adjacent selvage to the feeder F after the first shot of fresh filling across the loom.

Referring now particularly to Fig. 2, the normal relative position of the temple T and the auxiliary filling-detecting mechanism is shown, the temple thread-cutter comprising, essentially, a fixed cutting or severing blade a, inserted in a slot or opening in the body of the temple, and a cooperating relatively movable cutting or severing blade 0, bifurcated at its rear end to straddle the blade a and presenting two downturned portions 0 0 each terminating in a hook 0 substantially as in United States Patent No. 585,465. The blade 0 has a depending foot 0", to which is connected the free end of a spring 8, the opposite end of the spring being coiled at 5 around a stud 0 on the temple-body, the spring when free to act moving the blade 0 rearward and upward into operative position. (Shown in Fig. 3.) At such time the hooked portions 0 0 project beyond the temple-body, as in Fig. 3, in readiness to engage and hook over the filling end 2f, Fig. 3. Upon the stand g I have provided a depending ear 1, Figs. 2 and 3, having a lateral stud 2, upon which is pivotally mounted the hub 3 of a rocking connection or arm 4: 5, the part 4: depending below and behind the lateral projection 6 on the foot 0", with which the free end of spring a is connected. The upturned part 5 of the rocking arm is located in the path of movement of a lateral stud 7 on the auxiliary slide g", the relative arrangement of the parts 7 and 5 being such that when the slide is in normal position the lower end 4: of the rocking arm will press forward against the projection 6, flexing the spring 5 and maintaining the blade 0 retracted, the severing means for the filling end thus beinginoperative under normal conditions, as in Figs. 1 and 2.

Upon detection of filling failure by the auxiliary detector g, which will be after the shot of the shuttle toward the replenishing side of the loom, the slide g will be moved forward through its actuator or weft-hammerWV, and as the stud 7 is thus moved forward the spring 5 is permitted to move the blade 0 into the position shown in Fig. 3, rendering the severing means operative or setting it. If the main detector f first detects filling failure, which would be after the shot of the shuttle into the box B, Fig. 1, the auxiliary detector 1 will detect such failure after the return shot to the replenishing side of the loom, and

the blade c'will be operatively positioned in the manner just described. After filling replenishment the shot of the shuttle to box B, Fig. 1, will cause the fresh filling to be laid, and the filling end will extend from the feeder to the nearer edge of the cloth, and the lay will on its forward stroke beat in such fresh filling, while the filling end 2, will pass under the hooked end of the blade 0, as in Fig. 3, the blade being in operative position. As the lay swings back the slide g will move back to its normal position, and on such return movement as soon as the stud 7 strikes the end 5 of the rocking arm 4 5 the arm will be rocked into normal position, positively engaging the projection 6 and retracting the blade 0 into normal position and severing the filling end 6 before the next detecting pick of the fork g.

It is immaterial, manifestly, which fork first detects filling failure, for the severing means will always be set or placed in operative condition in time to cooperate with the filling end as soon as the fresh filling is beaten in, and the severing means will then be operated positively and promptly to sever the filling end before the next detecting pick (after replenishment) of the auxiliary fork.

The arm 4 5 is a controlling connection between the severing means and the adjacent fork, the latter positively and effectively governing the operation of such severing means.

By the invention herein described the filling end is removed from the path of the adjacent fork, so that the latter is perfectly free to operate in the proper and usual manner,

IIO

no mechanism being required to vary the fork action on account of the presence of the filling end, and, furthermore, the latter is promptly and positively severed from the cloth.

The temple herein shown and described can be set nearer the reed than can the ordinary thread cutting temple, because there is absolutely no danger of the cutting device severing the running filling, owing to the fact that normally the movable blade is retracted and completely housed and only operates upon detection of filling failure.

IVith the ordinary temple thread -cutter there is a possibility of the cutter severing the running filling.

Inasmuch as the cutting device in accordance with my invention operates only when the filling breaks or is exhausted instead of on every pick, the wear upon the parts is greatly reduced and the cutting-blades retain their sharpness for a long time.

My invention is not restricted to the precise construction and arrangement herein shown and described, as the same may be varied or rearranged in different particulars by those skilled in the art without departing from the spirit and scope of my invention.
