SPECIFICATION forming part of Letters Patent No. 568,455, dated September 29, 1896.

l Application filed June 17,1896. Serial No. 595,857. (No model.) i

To cir/ZZ whom, t may concern:

Be it known that I, JAMES H. N oRTHRor, of Hopedale,'in the county of Vorcester and State of Massachusetts, haveinvented an Im- 5 provement in Looms, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object the proio duction of a loom wherein means are provided to detect the shuttle when it has been improperly positioned in the shuttle-box and to automaticallyfprevent the transfer of a fresh supply of filling to the shuttle when in I5 improper position.

My invention isl particularly adapted to that class of looms wherein a plurality of lilling-carriers are supported in a filling-feeder, from which the lling-carriers are autolnatzo ically transferred one by one to the shuttle upon failure of the filling, such a loom being shown in United States Patents Nos. 529,940 and 529,942, granted to me November 27, 1894. The transfer of the fresh iilling-car- 2 5 rier to the shuttle is leffected while the shuttle is in the shuttle-box, and, obviously, if the shuttle is improperly positioned therein it will be impossible to properly effect the transfer of the filling-carrier, and the mechanism 3o is liable to break or smash.

In another United VStates patent, No. 529,943, I have shown one form of mechanism for detecting the improper position of the shuttle in the shuttle-box; but in my present 3 5 invention I have simplified the construction of the mechanism, and I have also mounted the shuttle-detector on the transferrer-support so that it preserves the same relative position tothe shuttle as do the other Work- 4o ing parts of the feeder.

Other features of my invention will be hereinafter fully described, and particularly pointed out in the claims.

Figure l is a transverse section of a suffi- 4 5 cient portion of a loom to be understood, with my invention applied thereto, looking toward the inner end of the filling-feeding mechanism looated at the right-hand side of the loom. Fig. 2 is a partial'end elevation of the mech- 5o anism shown in Fig. l and viewed from the right-hand side of the loom. Fig. 3 is a similarview with the parts in position to effect the transfer of a fresh filling-carrier to the shuttle if the latter is properly positioned in the'shuttle-box, and Figs. 4, 5,6, and 7 are de- 55 tached deta l views to be referred to.

The loom-frameA, the breast-beam A40, the lay A3, having the bottom of its shuttle-box cut away below the self-threading shuttle S, the filling-feeder'comprising connected rota- 6o table plates suitably shaped to receive the ends of the lilling-carriers h, one of which is shown in dotted lines, Fig. l, the weft-threadsupporting platel b', the weft-end holder h2, the stud j', the pusher f, mounted thereon 65 and having'the forked depending end f3 and a projection 2l, the arm f6, havingv thereon the tip-supporting device f s, (see dotted lines, Fig. 1,) and the shaft d', adapted to be rotated by the movement of theweft-fork in the ab- 7o sence of the lilling, are and may be all as represented in said Patent No. 529,942, wherein like letters are used to designate like parts, the parts hereinbefore referred to being operated in practice substantially as therein 75 provided for.

The chute h, secured to a spring-controlled arm h', pivoted on a stud h2, and the arm h5, connected to the rock-shaft d and having a pin hw to enter a cam-slot h3 in an arm hw on 8o the stud h2, cooperating with the arm h to control the movement of the chute and position it `ready to receive the filling-carrier ejected from the shuttle, are also substantially as shown and described in said Patent 8 5 No. 529,942 referred to.

The rock-shaft d has secured thereto an arm d2, connected to one end of a spring d3, the other end of the spring being connected to the loom-frame, and a link d4 is jointed at 9o .its lower end to the arm cl2, the upper end of said link having a longitudinal slot d5, entered by a pin or stud c on one of the arms c of asleeve or hub c. (Shown separately in Fig. 5.) Thus hub cis rotatably mounted 95 on 'the stud f, and a second upturned arm c2 is pivotally connected to one end of an adjustable link e, the other end of the said link being jointed at e to an arm It of a hub k, providedwith a downwardly and laterally :toc bent arm k2, which forms the shuttle feeler or detector. The link e comprises a rod threaded at each end in the same direction and screwed into the threaded end pieces, which latter are pivoted to the arms c2 and k', respectively, the link being adjusted to the proper length when the loom is first set up.

It sometimes happens that loom attendants will tamper with the mechanism in such a way as to throw it out of adjustment, and by the construction herein shown the length of the link cannot be changed without removing it from the loom.

An arm kx, .rigidly secured to the stud f, as herein shown, is provided with a laterallyextended pin or stud 7a3, (see dotted lines in the drawings,) upon which the hub 7c is pivotally mounted, the detector-arm 7.52 being bent, as shown in Figs. l and 5, to clear the adjacent parts of the mechanism as it operates, the lower end of the arm being turned toward the lay to engage the shuttle if the latter is improperly positioned in the shuttlebox.

The forked depending end f3 of the pusher f has mounted therein a rockerstud m, (clearly shown in Fig. 4,) provided with a disk-like head m', and one end of a spring s, surrounding the stud between the head and the end f3, is secured to said head, the other end of the spring being secured to the end f3, the spring normally tending to turn the stud in the direction of the arrow l0, Figs. 2, 3, and Il. An arm m2 is secured to the stud m and has on one side an ear m3, on the opposite side, near its extremity, a lug or projection m, while a notched dog mx is ad justably secured to the arm 'm2 by set-screws 5 and G. The dog 'fax is moved into position, as will be described, to be engaged by a bunter C2 on the lay when a filling-carrier is to be trans ferred from the filling-feeder to the shuttle by the pusher j", provided the shuttle is properly positioned in the shuttle-box.

The hub c (see Fig. 5) has a third arm c, extended oppositely to the arm c, downturned and bent laterally at o4, and then down and inwardly, as at c, and to the part ci lis rigidly attached a downturned finger n, the base of said finger being preferably slotted at n to receive the bolt nx, connecting it to the part e5 of the arm c3, in 4order that the linger may be adjusted thereon. The finger n extends down over the lug m" on the arm m2 and at times controls the latter, as will now be described.

ln Figs. l and 2 the parts are shown in the position they occupy when the loom is running properly, and it will be not-iced that the dog mx is depressed, so that its notched end is not in the path of the bunter C2. It will be noticed that the link d* is held in its lowered position by its connection with the rock-shaft d', and the said link, act-ing on the arm c of the hub r, depresses said arm, thereby holding the bent arm c3 of said hub elevated and with the finger n toward the front of the loom. This finger, acting' upon the projection mx on the arm m2, swings the latter forward, turning the stud m against the force of the spring s, such position of the arm m2 maintaining the dog mx in inoperative position and forming a detent therefor. If, however, the filling should fail for any reason, the rock-shaft d will be turned, as in United States Patent No. 529, 940, elevating the lilik d'1, and thereby allowing the hub c, with its arms, to turn on the stud f. The spring s immediately acts to turn the stud m in the direction of the arrow lO, Figs. 2, 3, and et, to throw the dog mx up into operative position, Fig. 3, into the path of and to be engaged by the bunter C2 when the lay next comes forward. spring swings the arm m2, its lug m4 acts upon the finger n, moving it inward and thereby depressing the arm c3, so that the arm c2 is swung outwardly into the position shown in Fig. 3. The link c in consequence pulls the upper end of the arm tover and throws the shuttle feeleror detector 752 into the position shown in Fig. 3, and if the shuttle is properly positioned in the shuttle-box the said feeler will not be engaged thereby, and the bunter, acting upon the dog mx, will swing the end f3 of the pusher j" to depress the latter and transfer the filling-carrier to the shuttle. The direction of the pressure exerted by the bunter upon the dog is in a direction upwardly inclined toward the forked end f, so that the said end will. be moved with the dog instead vof having the effect of swinging the dog relatively to said forked end, as would be the case if the pressure was in a downward direction.

If the shuttle is improperly positioned in the shuttle-box it willmeet the fceler 7a2 in the forward movement of the lay and will swing it on its pivot 7a3, thereby moving the arm k in the opposite direction and, through the link e and arm c2, turning the hub c to swing the arm e3 outwardly. This movement of the arm c3 causes the finger `it to engage the lug m and thereby swing the arm m2 to rock the stud m in the direction opposite to the arrow l0 to depress the notched face of the dog/nr1 and move it out of the path of the movement of the bunter C2, the said dog being' moved into substantially the position shown in Figs. l and 2. This movement of the dog relative to the forked end f3 of the pusher is effected because the pressure applied to said dog is exerted altogether below the pivotal. point of the arm m2, and inasmuch as the pusher is only operated when the dog is engaged by the bunter the pusher will not be operated to transfer a filling-carrier to the shuttle when the latter is improperly positioned.

lVhen a filling-carrier has been properly inserted into the shuttle, the rock-shaft d returns to its normal position, as in the patent referred to, and through the link d restores the parts to normal position occupied when the loom is running properly.

My invention is not limited to the precise construction or arrangement of' parts herein described, as the same may be modified or As the IOO IIO

rearranged without departing from the spirit and scope of my invention.
