AUTOMATIC FILLINGREPLENISHING LOOM.

SPECIFICATION forming part of Letters Patent No. 725,194, dated April 14, 1903. Application filed October 31,1902. Serial No.`129,550. (No model.)

To 1f/ZZ whom t '1n/ty concern:

Be it known that I, Louis A. AUMANN, a citizen of the United States, and a resident of Chicopee, county of Hampden, State of Massachusetts, have invented an Improvement in` Automatic Filling-Replenishing Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings Io representing like parts.

This invention relates to looms of the type wherein upon a substantial or predetermined exhaustion of the filling in the shuttle means for controlling thef'operation of the loom will t5 be actuated to cause or bring about automatically replenishment of the running or Working nlling or a stoppage of the loom, as the case may be, looms of such type being technically knownV as feeleil'oomsf7 inasmuch zo as the operation of the loom is controlled by or through the agency of a feeler, which intermittingly feels the Iilling in the shuttle and indicates the substantialexhaustion thereof'.` 5

Filling-replenishing may be effected either by the substitution of a full shuttle for the running and nearly-empty shuttle or by t-he introduction of a fresh supply of filling into the running shuttle Whenits previous supply 3o is exhausted to the desired extent. My present invention, however, is not restricted to either form of replenishing mechanism; but for convenience I have herein shown it in` connection with the latter form.

The feeler in a feeler-loom intermittingly engages and is moved or vibrated by the lilling` in the shuttle, and the extent of such movement is at its maximum when the full supply of filling is present, the diminution of 4o the latter as it is woven off causing a gradual decrease in the filling-induced movement of the feeler until the minimum is reached, whereupon through suitable instrumentalities filling replenishment or stoppage of the loom is effected in a manner well known to those skilled in the art. This minimum may be only a very slight movement, or it may be no movement at all, according to circumstances, the parts being so adjusted that the 5o minimum is reached when there is substantial .exhaustion of the filling in the shuttle, only enough remaining to traverse 'the lay a few times.

In order to reduce the Waste filling tothe smallest practicable or possible amount, it will be manifest that the adjustment must be accurate and quite ne, and when once adjusted it should answer for varying speeds of the loom without further attention. To those skilled in the practical use of'looms, how- 6o ever, it is well known that there is an appreciable difference in the actual stroke of the lay when the loom is running, because of slight lost motion of the different parts, so that if the lay reaches a certain point on its front center when the loom is running at a given speed at another speed the lay may overrun that point or fail to quite reach it, as the case may be, owing principally to va-` riations in the momentum of the lay and the 7o looseness of connections. It will be manifest, therefore, that if the feeler is so adjusted as to effect a change in the operation of the loom when desired filling exhaustion has been reached a difference in the forward beat of the lay will tend to edect such change too soon, producing undue waste of filling, or it will delay the change in operation beyond the proper tlme,'so that one or more picks may be made with no filling laid, thus defeat- 8o ing the object of the device.

Various means have been devised to overcome improper action of the feeler hereinbefore referred to and with more or less success in practice; but so far as I am aware they have all depended for their operation upon 'coperation with the shuttle itself or something carried by or movable with it. 'This is somewhat objectionable for various practical reasons, although the underlying principle is 9c good, because the filling-carrier in the shuttle always bears a substantially fixed relation to the side wall of the shuttle or to some part upon or moving with it, and by my invention I have provided for properly positioning the feeler for feeling action independently of the shuttle or any part thereof.

My present invention has for its main object the production of means acting independently of the shuttle to neutralize or pre'- too Vent in a feeler-loom accelerated or retarded action of the feeler, due to irregular or varying movement of the lay from whatever cause it may be due. This and various other novel features of my invention will be hereinafter fully described, and particularly pointed out in the following claims.

Figure l Ais a top or plan View of one end of the lay and breast-beam of a loom of the feeler type with one embodiment of my invention illustrated in connection therewith, a shuttle being shown in the non-replenishing shuttle-box. Fig. 2 is a left-hand side elevation of the parts shown in Fig. l and with a portion of the replenishing mechanism indicated, such mechanism herein being located at the right-hand side of the loom. Fig. 3 is an enlarged detail View, in rear elevation, of the feeler, its movable support, and some Of the parts controlled by the feeler. Fig. 4 is a transverse section on the irregular line 4 4, Fig. l, looking toward the right and with the lay on its front center, it being supposed that tilling replenishment is just about to be effected. Fig. 5 is an. enlarged sectional detail on the line 5 5, Fig. l; and Fig. 6 is a similar view, alsor enlarged, on the line 6 6, Fig. 3, looking toward the left.

- The breast-beam A40, lay A3, provided with a shuttle-box BX, having an aperture 3 in its front wall 12X, the feeder F, Figs. 2 and 4, to hold the reserve supply of filling in the form of filling-carriers, the transferrer f', and the operating or controlling rockshaft d', the notched holding-plate N for the shipper NX,

' (the only member of the stopping mechanism shown,) and the automatically self-threading shuttle S, adapted to contain a supply of filling, such as a filling-carrier b, and having a hole 4 in its side wall, may be and are all of well-known or usual construction and substantially as in United States Patent No. 648,986, dated May 8, 1900.

A member oi the means for controlling the operation of the loom, herein designed more particularly to actuate a lling-replenishing mechanism, is shown as a latch cx, pivotally mounted on a latch-carrier c5, fulcrumed on a slide c, located adjacent the guide for the usual slide fm, on which is fulcrumed the tilling-fork mx, the weft-hammer W, Fig. l, acting in usual manner upon failure of filling to move the slide m outwardly to operate the knock-o lever n n2 and release the shipper to stop the loom. A spring s2 acts to lift the latch from its normal operative position into inoperative position whenever a dog, to be described, is withdrawn by or through llinginduced movement of the feeler from beneath a depending foot c6 of the latch-carrier, the latch when operative being in the path of a shoulder wx on the weft-hammer, the latter constituting an actuator for the slide. When the said shoulder engages the latch, the slide c is moved outward and rocks an upturned Varm d3, fast on the rock-shaft d', turning the latter and, as herein shown, effecting filling replenishment, all substantially as in the patent referred to. On its rear edge and just beyond the slide c the breast-beam has aprojection ctx, in which is xed an upright headed fulcrum-stud a, passing through a counterbored hole in a boss hX, near one end of a swinging feeler-support, shown as an elongated arm h h', the part 71. at the outer end of said arm being downturned below the holding-plate. N, the boss hX resting upon the top of the projection ax, (see Fig. 3,)the head a' of the stud entering the counterbore and preventing lifting of the adjacent end of the feelersupport. The foot of an L-shaped bracket nl? on the holding-plate and turned toward the back of the loom projects beneath and supports the said part h', a depending bolt 5 on'the latter, Fig. 6, extending through an elongated slot m13 in the bracket and having a washer G and nut 7 on its lower end permitting the outer end of the feeler-support to swing and slide upon the bracket-foot toward and away from the breast-beam. Alug h2 on said support carries a pin 8 to guide the outer end of a spring S5, interposed between the lug and the bracket w12, the spring tending'to swing the free end of the feeler-support rearward, a notch n, Fig. 6, receiving the frontend of the spring. A second lug h3 on the feeler-support has. loosely extended through it a headed stud 9, screwed into a hole in the rear edge ofthe holding-plate and held in adjusted position by a check-nut 10,

.the head 11 of the stud acting against the rear face of the lug h3 to limit the spring-induced movement of the feeler-support, and by adjusting the stud it will be manifest that the extended position of the feeler-support may be changed, the purpose of such adjustment being more clearly apparent hereinafter. Two upturned stands h4 h5 on and at the opposite ends ot' the feeler-support provide bearings for a dog-carrier, shown as a substantially horizontal rock-shaft h6, having secured upon it near the stand h4 a collar h?, preferably held in an adjustable manner by a set-screw 12. As best shown in Fig. l, the stand h4 is quite near the slide c, and it is convexed at its top to permit an overhanging arm 718 on the collar to swing over it when the rock-shaft or carrier h6 rocks, said arm having rigidly secured to it a preferably-hardened steel plate or dog 71.9, the shape thereof being shown in Figs. l, 2, and 3. This dog extends beneath the foot cG of the latch-carrier and tilts the latter against the spring s2 to thereby hold the latch 0X in the pathof its actuator-viz., the shoulder wx of the weft-hammer. At such time the dog abuts against an upright fixed stop b10 on the guide for the slide c and is yieldingly retained against it by a spring s6, faxed at one end to a pin 13 on the loomframe and at its other end attached to a .flexible band or stra-p 71.10, led up to and partly around a sheave h, fast on the rock-shaft h6, the end of the strap being secured to the sheave. Manifestly the tendency of the IOS IIC

spring is to turn the shaft in the direction of i the arrow 14:, Fig. 3, and if the shaft be oppositely turned it will be obvious that the dog hf will be withdrawn from beneath the foot of the latch-carrier and the spring s2 will immediately act to lift the latch cX into inoperative position.

The feeler is herein shown as a thin dat plate f, located opposite the aperture 3 in the shuttlebox wall b and mounted to slide longitudinally in a horizontal grooved holderf2, having a depending ear f3, provided with an elongated slot f to receive a clamping-stud f5, screwed into the outer face of the stand h5 on the feeler-support, adjustment of the feeler vertically being thereby provided in order that the feeler may move in a horizontal path at the proper height with relation to the shuttle.

Referring to Fig. 1, it will be seen that the longitudinal axis of the feeler is inclined to the feeler-support, but at right angles to the rock-shaft h6, the ou ter end of which projects over the feeler and is connected therewith by means to be described. As the feeler itself is thus at a slight angle to the longitudinal axis of the shuttle and the filling-carrier b therein, the feeling edge fx of the feeler is slightly beveled to be in substantial parallelism to the filling-carrier in order to squarely engage the filling, it being understood that on the forward beat of the lay the feeler passes through the aperture 3 in the front box-wall bx, and on every alternate pick it also enters the shuttle through the hole or slot 3 in its side wall. Owing to the relative position of the feeler and the foot cof the latch-carrier, the rock-shaft is diagonal to the front of the lay as the rock-shaft is operated by fillinginduced movement of the feeler, and because of this latter fact the sliding movement of the feeler is at right angles to said rockshaft. The feeler has two upturned transverse ears 16 17, which receive a screw f1, held in adjustment by a check-nut fu, the screw having an annular groove fm between the ears, Fig. 5, to receive the forked or bifurcated end of a depending rocker-arm hw, made fast on the rock-shaft h6 by a set-screw 19. Adjustment of the rockerarm and screw fw determines the position of the edge fX of the feeler relatively to the rear edge of the part 7L of the feeler-support when the feeler is fully eX- tended and the dog hf against the stop Z110" that is, when the latch is in its operative position.

It will be noticed by reference to Fig. 1 that the part h of the feeler-support is wider than the part h thereof, so that the rear edge 72,13 is nearer the lay and parallel thereto, and I have herein provided that some part of the lay on its forward beat shall engage such edge and slightly swing the feeler-support on its fulcrum c when the lay reaches front center.

In Fig. 4 the front downturned edge of the race-plate 19X of the lay is shown as the part of the lay which engages and moves the feeler# support against its spring S5; but any other suitable partof the lay may be used,if desired.

The feeler-support is adjusted by means of the stud 9, so that the edge 7113 will always be engaged by the lay on its forward beat and slightly'moved thereby, the adjustment being determined by the minimum distance which the lay traverses on its forward beat. Such adjustmentand movement of the feelersupport acts to properly position the feeler for feeling action on each beat of the lay, though feeling action occurs on alternate beats only, as is well understood, for whether the lay moves beyond or not quite so far as its theoretical stopping-point when at front center the feeler will always occupy the same position relative to the longitudinal axis of the shuttle when in the shuttle-box BX.

The adjustment effected by the screwflo determines how much filling shall be left in the shuttle when filling replenishment is effected, the screw being turned in or out until the thickness of the yarn on the barrel of the filling-carrier when filling replenishment is effected shall be such that the feeler will not be moved by engagement therewith sufficiently to withdraw the dog 71,9 from beneath the foot c6, such a condition of affairs being illustrated in Fig. 4. It will be seen that by turning the screw out there will be more lling left in the shuttle when replenishing or stopping of the loom is effected,while by turning it in the quantity of filling remaining will be smaller, and such adjustment can be effected with great nicety. Now supposing such adjustment to be made it will be obvious that unless some means are provided for counteracting it an irregular or variable mo vement of the lay will cause the feeler to effect lilling replenishment or loom-stoppage too soon if the lay-stroke is short or too late if the laystroke be longer than it should be.

By mounting the feeler as herein described,

so that it will be properly and uniformly positioned relative to the longitudinal axis of the shuttle by the movement of the lay, the objectionable results due to irregular movement thereof will be completely obviated or counteracted.

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