T0 at whom it may concern.-

7 Be it known that I, JoNAs NORTHROP, a citizen of the United States, and a resident of Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Hopper-Actuziting Mechanism for Automatic Looms, of which the following description, in connection with the-accompanying drawings, is a specification, like numerals on matic type, wherein the running filling is re-,

plenished from time to time by insertion of a fresh supply of filling into the shuttle.

United States atent to Northrop,. No. 529,940, shows a com of this general type, and laterpatents show various devices for advancing the hopper step by step to bring. into position to be transferred one after another of a plurality of filling-carriers or bobbins held as a reserve supply in the hopper.

In In present invention I have provided means or effecting the advance of the hopper after each operation of the transferrer, the latter acting to transfer the filling-carriers from the hopper to the shuttle in such a manner that the motion imparted to the hop-' per will be without sudden shock or jar, and I have also provided novel means for limiting-the advance of the hopper to a predetermined distance.

In order that the hopper may not turn backward when the advancing mechanism is being set preparatory to the next advance, a detent is provided. I i

When the attendant wishes to fill the hopper, it is sometimes necessary or convenient to move the hopper freely in either direction, and herein I have provided means whereby by manual movement of a single member of the controlling mechanism the hopper is entirely freed from such mechanisms and can be moved in either direction by the attendant and the filling-carriers placed therein as required. i I have illustrated my invention in connection with a rotatable hopper of the Northrop type, such as shown in the patent hereinbefore referred to, and in order to control the said hopper Ihave provided feed, detent,

rotatable with the hopper, the stop-pawl be-' ing automatically retractedby or through the setting movement of the feed-pawl, and

y manual retraction of one of said pawls,-

isengaged from the ratchet to free the hop er.

b preferably the feed-pawl, all of the pawls are These and other novel features of my mand stop pawls to cooperate with a ratchet vention will be fully described in the sub:

joined specification and particularly pointed out in the following claims.

Figure 1 is a transverse sectional view of the hopper of an automatic filling replenishing loom of the Northrop type, taken across the axis of rotation of the connected disks comprising the hopper and with one embodi thereto, the parts being shown in normal position inreadiness for the next filling-carrier to be, transferred when called for. Fig.2 is a similar view, a portion of the hopper-disk being omitted asunnecessary, but showing the parts in the position desired at the instant that the transferrer has completed its operative movement to insert a fi rier in the shuttle, the feed-pawl having been set in readiness for the next advance of the hopper and the stop-pawl being shown as retracted to permit the initiation of such ad vance movement. Fig. 3 is a view similar to Fig. 2, but showing the hopper as freed from ling-can the control of its operating mechanism. Fig.

4 isa' side elevation of the transferrerdetached. Fig. 5 shows side and rear edge views of the feed-pawl. Fig. 6 shows side and top plan views of the stop-pawl; and Fig. 7 is a detached view, in side elevation, of the detent-pawl.

Inasmuch as the filling replenishing mechanism, broadly speaking, and the means for I actuating the transferrer are not of my invention, the same being well known to those skilled in the art, it will be suflicient to state that the hopper in practice comprises two connected disks or plates, the inner one, as 1, being herein shown rotatably mounted on a disk or stud 2, fixed to the hopper-stand 3, mounted on the breast-beam 4 of the loom.

The filling carriers or bobbins 5 aresuitably held by their butts and tips by and between the two disks of the'hopper in a cirou larly arranged series, as shown inv Fig. 1, and

7 O ment of my novel hopper mechanism applied by intermittent advance or step-by-step movement of the hopper said filling-carriers are brought one by one into transferring position adjacent a stop 6 to be engaged by the rocking transferrer 7, and thereby transferred from the hopper to the running shuttle all in well-known manner.

The transferrer 7 has its hub 8 mounted to rock on a horizontal stud 9, and it isretracted or lifted to normal position by a spring (not shown) and positively depressed or rocked on its operative stroke or movement by wellknown mechanism on the beat up of the lay.

I have herein shown a circular ratchet 10, secured to and to rotate with the hopper, and in actual practice the ratchet is secured to or formed on the outer face of the disk 1, its

v teeth corresponding to the number of holding devices for the filling-carriers.

The transferrer in my present invention is slightly different in certain details of construction, and, as best shown in Fig. 4, the said transferrer is provided with an upturned and enlarged extension 11 cut away at its lower portion and offset laterally, as at 12, the parts 11 and 12 being in different vertical planes, the offset portion 12 having a lateral pin or stud 13 thereon, and adjacent the ont end of the extension a shelf 14 is provided having an upturned projection 15, the shelf forming a spring-seat and the projection serving to position the s ring upon the seat.

The feed-pawl by whic 1 the advance movement of the filling-carrier is eflected is shown separately in Fig. 5, and consists of a casting having a main body portion 16, provided at its rearward corner with a slightly-hooked finger 17, and at the outer corner the body is upturned, as at 18, and provided with a broad lateral tooth 19 to cooperate with the ratchet 10. Oppositely projecting from the extension 18 is a finger-piece 20 for a purpose to be described, and viewing Fig. 5 it will be seen that the finger 17 is slightly offset from the body portion of the pawl.

A depending foot 21 is provided with an elongated slot 22, and in front of the slot is located an overhanging shoulder 23, having a depending tip 24, which enters the upper end of and retains in position a coiled actuating-spring 25, (see Figs. 1, 2, and 3,) this spring being interposed between the shoulder 23 and the seat 14 on the transferrer hereinbefore referred to.

The pin or stud 13 on the transferrerloosely enters the slot 22 at the lower portion of the feed-pawl, and, observing Figs. 1, 2, and 3, it will be seen that while the cooperation of the slot'and pin constitutes a positive connection at times between the transferrer and the feedpawl it is a lost-motion connection, permitting not only a rocking movement of the feedawl with relation to the transferrer, buta so a bodily longitudinal movement of the pawl for a purpose to be explained.

The slot extension 21 bears against the face of the offset 12 of the transferrer, and the main or body portion of the pawl bears against the opposed face of the enlargement 11, the two parts 11 and 13 being offset from each other sufficiently to permit the easy insertion and movement of the feed-pawl between them.

The transferrer is firmly mounted on its fulcrum-stud (as is well known to those familiar with this type of loom) and has practically no lateral movement and the width of the pawl-tooth 19 is such that its inner end is close to the outer face of the hopper-disk 1. Thus the feed-pawl cannot become displaced laterally 011 the transferrer, and its 11])-ft1](l.- down movement is limited by the slot-andpin connection. The actuating-spring 25 is of sufficient strength to advance the hopper a predetermined distance after the feed-pawl has been set, as will be described, such setting compressing the spring, as shown in Fig. 2.

Supposing a transfer is about to be effected, the downward movement of the transferrer from the position shown in F 1 to that shown in Fig. 2 operates to bring the stud 13 against the lower end of the slot 22, and the toothed feedpawl clicks over one tooth of the ratchet as the pawl is positively set or moved into operative position. This setting movement of the pawl, effected positively by or through the operative movement or stroke of the transferrer, serves to compress the actuating-spring, as shown in Fig. 2, wherein. the pawl is shown in position ready to effect the advance of the hopper. The rise of the transferrer as it returns to normal position permits the spring to act upon the feed-pawl to lift the latter, and thereby tlu'ough its cooperation with the ratchet to advance the hopper, and just before the transferrer has completed its upward stroke the hopper will have been advanced the full predetermined distance, so that the stud 13 is moved upward a short distance away from the bottom of the slot 22 as shown in Fig. 1, the spring effecting the advance of the hopper in a yielding manner, as will be maniest, and preventing shock or jar.

In order to prevent retrograde movement of the hopper under normal conditions, and also to prevent any reverse movement during the setting( of the feed-pawl, a detaining device or detent-pawl is provided to cooperate with the ratchet, said pawl 26 (separately shown in Fig. 7) having a ratchet-engaging tooth 27 and an adjacent rearwardly-extended arm 28, provided with a hook 29 at its extremity, and the lower portion of the pawl eccentric to its hook 30 is enlarged, or widened, a s at 31, the hook being mounted. to rock on a fixed fulcrum-pin 32 on the hopper stand 3. The detent-pawl is thus located between the transferrer and the innermost I dish 1 of the hopper, tooth 27 engaging the ratchet below the feed-pawl tooth 19'. When the hopper is advanced, the detent-pawl clicks over the ratchet, and its weight causes it to drop rearwardly into the next tooth and to prevent rotation of the hopper in a direction opposite to the arrow 100,- Fig. 1. A lateral lug or projection 33 is formed on the outer face of the detent-pawl for a purpose to be described Referring to Fig. 2, it will be seen that the detent-pawl remains in operative engage ment with the ratchet during the setting movement of the feed-pawl, so that at such time the hopper cannot be jarred or accidentally moved in a retrograde direction A second laterally-extended lug or projection 34 is formed on or secured to the dete'nt-pawl at its upper end substantially opposite to the tooth 27 and in such position relatively to the finger 17 that when the feed-pawl is manually retracted the finger will engage the lug 34 and will retract the detent-pawl from engagement with the ratchet, such manual retraction being effected by the operative grasping the finger-piece and swinging the feed-pawl forward into the position shown in Fig. 3, thus clearing or freeing the hopper from the control of its feed mechanism and the detent device. This will be referred to hereinafter. I have provided a novel and efiicient stop to prevent overrunning of the hopper when it is advanced andto limit the advance movement to a predetermined amount. I To this end I have provided a stop-pawl 35, (see Fig. 6,) having a tooth 36 at its rear or free end provided with an upright face 37, adapted to cooperate with the leading face of one of the ratchet-teeth, and at its outer end the stop-pawl is provided with a semihub 38, which loosely embraces the transferrer-hub 8. The stop-pawl is thus mounted to rock concentrically with the axis of the transferrer, and it extends rearwardly to the-ratchet, passing between the detentpawl 26 and the feed-pawl. The hook 39 on the free end of the stop-pawl has attached to it one end of a spring 40 the other end of the spring being attached to the hook 29 on the extension 28 of thedetent-pawl, the spring by its contraction tending to swing upward the stop-pawl toward the detent-pawl and retaining the tooth 36 of the stop-pawl in operative engagement with a ratchet-tooth under normal conditions. The stop-pawl is provided with cams 41and 42, and a lug'43, extended laterally from the inner face of the body 16 of the feed-pawl, is "arranged to co,- operate with one or the other of the cams.

When the feed-pawl is set, the downward movement thereof causes the lug'43 to engage the cam 42 and depress or'swing downward the stop-pawl 35 disengaging the tooth-face 37 thereof from the ratchet, as shown in Fig. 2, so that the ratchet can advance on the feed movement of the feed-pawl far enough to carry the last-engaged tooth beyond the face 37 of the tooth of the stop-pawl. The advance of the hopper is initiated before the spring 40 is free to lift the stop-pawl into the path of the next tooth of the ratchet, the lug 43 cooperating with the cam 42 long enough to permit such initial movement of the hopper. As the advance of the latter is continued, however, the stop-pawl rises until it engages the fresh tooth of the ratchet, and when the stop-pawl and ratchet are in the relative position shown in Fig. 1 it will be seen that further advance of the ratchet cannot be effected, for the push of the hopper is transmitted through the stop-pawl in a line which substantially passes through its axis. Hence the hopper is stopped after a predetermined The rise of the stop-pawl is of advance. course limited by the engagement of the point of the ratchet-tooth with the corner formed by intersection of the faces 37 and 44 of the stop-pawl. There is no direct connection or engagement at any time between the transferrer and the ratchet, the-hopper advance being efiected by or through the actuatingspring 25, and its stoppage when advanced by or through the cooperation of the stoppawl and ratchet, as explained, so that there is no hard bump on the endmost filling-carrier of the series when the latter is moved into transferring position against the fixed stop 6. 'e v If theoperative desires to free the hopper from its controlling means, hereinbefore described, so that it can be turned freely in either direction, for the purpose of inserting filling-carriers or for any other purpose needful, he grasps the finger-piece 20, pulls the feed-pawl forward, the latter swinging at such time on the pin 13 as a fulcrum, and the finger 17 by cooperation with the lug 34 of the detentpawl withdraws tooth 27 of the latter from the ratchet as the manual retraction of the feed-pawl withdraws its tooth 19 from engagement with the ratchet. As the feed-pawl is thus retracted the lug 43 thereon is brought into engagement with the cam 41 on the stop-pawl 35, and the latter is depressed or swung downwardly about its fulcrum into the position shown in Fig. 3, withdrawing its tooth from engagement with the ratchet, so that the hopper is freed entirely from engagement with all three pawls and the operative can turn the hopper on its axis, as desired. By rasping the hook 29 on the free end of the fetent-pawl and pulling the latter forward the tooth 27 is withdrawn from the ratchet, and the lug 34 on the detent-pawl en ages the adjacent edge of the part 18 of t e/feed-p'awl and swings the latter forward, withdrawing its tooth 19 fromthe ratchet, the feed-pawl then acting,

either one of the feed or detent members can be disengaged from the ratchet by or through manual disengagement of the other member from said ratchet.

The lug 33 on the lower portion of the detent-pawl projects beneath the stop-pawl and limits its downward movement and at the same time acts in an indirect way to limit the manual retractive movement of the feed and detent pawl. When the finger-piece is released, the feed-pawl returns to operative position by expansion of the spring 25, and the detent and stop pawl are restored to position in which they can cooperate with the ratchet, and if the hopper has not been left by the operative in such position that the teeth of the several pawls can immediately and properly engage the ratchet a slight movement of the hopper will carry the points of the ratchet-teeth forward far enough to permit the immediate positioning of the several pawlteeth, restoring the parts to the condition shown in Fig. 1. The detent-pawl cooperates with the ratchet at a point intermediate the feed and stop pawls in the construction herein shown and described.

Changes ormodifications in the details of construction may be made by those skilled in the art without departing from the spirit and scope of my invention, one practical em bodiment of which is herein shown and described.
