FILLING CLAMIPIN'G AND PAaTING MEANS FORYLOOMS.

Application filed July 16,

To all 207mm it may concern:

Be it known that I, ALoNzo E. RHOADES, a citizen of the United States, residentof Hopedale, county of Worcester, State of Massachusetts, have invented an Improve ment in Filling Clamping and Parting Means for Looms, of which the following description, in connection with the acc mpanying drawing, is a specification, l ke characters on the drawing representing llke parts. p This invention relates to automat1c filling replenishing looms wherein the running filling is replenished prior to complete exhaustion and wherein the old or spent filling 1's parted between the cloth and the shuttle by a clamping and parting means mounted upon a carrier, such as the usual swinging shuttle feeler, so as to be moved bodily rearwardly and forwardly or toward and from the lay. Q r The object of the invention is'to provide a construction in which the operation of the filling clamping and parting device is secured by a striker arm movable withthe filling carrier support commonly provided in this type of loom and which acts to close the filling clamping and parting device when in operative position and which is yieldingly movable with respect to -the filling carrler support upon the occurrence of any abnormal resistance. v p

The object of the intention is further to provide a construction of this character in which the striker arm is mounted in a housing on the side of the filling carrier support and which thus presents a simple and effective construction which may readily be added to existing looms. I

These and other objects and features of theinvention will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claims.

The drawings illustrate the invention'as embodied in a preferred form in theswell known Northrop type of automatic filling replenishing loom. .The invention in some respects is an improvementupon the-com strfuctionillustrated described in my prior application No. 469,599, filed May 14, 1921. r

In the drawings:

Fig. 1 is a transverse section of a portion of an automatic filling replenishing loom Specification of Letters Patent. P t ted M 514, 1 22;

1921. Serial No. 485,155.

with a preferred form of the present'ii'iven tion embodied therein, only those parts be-" ing illustrated which are necessary to the disclosure of the invention.

Fig. 2 is a view similar to Fig. 1 with many of the parts therein shown omitted and showingthe filling clamping and part ing device inposition ready to be closed upon the filling.

Fig. 3 is a front end elevation partially in vertical cross section of the construction shown in Fig. 2. v The construction and operation of the automatic filling replenishing loom herein illustrated being well known and familiar to those skilled in the-art, it will he neces sary to describe in detail only-'those'features" and their operation immediately concerned Wlth the pr invention.

The loom frame 1 supports the magazine or hopper 2 containing the supply offr'esh filling carriers herein-shown as bobbins '8;

hen the running filling in the shuttle 4011 the lay 5 has become substantially exhausted,

indication of that fact I is transmitted through a well known. mechanism to the rod or rock shaft 6 which is thereupon rocked to' raisethe arms? and swing the shuttle feeler 8 rearwardly and at the samejtime to I raise the dog 9 connected to the tran'sferrer 10 into the path of a hunter 11 on thelay;

If the shuttle is pro p'erly: boxed-allowing the shuttle feeler to pass the end: of the.

shuttle, then the bunter 11 strikingthe dog 9' swings. the transferrer 10 downwardly forcing a fresh filling carrier 3 from its tion in the magazine down onto the-lay, and in this case into the shuttle '4; therebeneath simultaneously ejecting the substantially exhausted filling carrier from the lay. 1

When the fresh'filling carrier isinthe magazine 2. ready for transfer, it rests against an abutment 12 13 pivotedat 14:- in the k that, in order topassout from the magazine, this support l3'must be swung downwardly about its pivot. This filling carrier'support 3, which is a fa'miliardevice'in this "type of loom, is rigidly connected to the pivot 14 which extends to the front or opposite-side of the magazine and-is there provided with posiand over a support magazlneframe'so anfupwardly extending'arm 15.1 This arm slotted lug 19 projecting from the magazine 2 and a helical spring 20 surrounds the pin between this lugand its opposite head 21. Thus the pivoted or swinging support 13 is normally held in the position illustrated but may move or swing downwardly against the tension of the spring 20 whenthe transfer or the fresh fillingcerrier takes place. It thls device which 18 utilized to secure the operation of the filling clamping and parting device when, and' only when, afresh filling carrier is transferred fromthe magazine to thelay.

The shuttle feeler 8 acts as -a carrier for the fillingclamping and parting device. In the form. illustrated the movable blade or member 22 of this device is pivoted at 23 to the shuttle ieeler and swings upwardly at its rearward or effective .end to close upon the co-operating elements of. the device and clamp part the filling. The rearward end of the shuttle feeler is also-at its lower edge beveledor inclined upgwardlyas shown at24=1to insurethefilling, extending from.

the {shuttle to the fell, being guided into the field of; action of .the filling clamping and parting device.

The general operation is a familiar one. Upon the call for :fillingaeplenishment, .the shuttle vfeeler 8 is swung @rearwardly,' the I movable blade122 is swung to open position,

the filling clamping and parting device passes over the fillingextending from the substantially exhausted fillingcarrier to the fell. The movable blade is then swung to closing position-parting and clamping the filling, and then when the shuttle feeler swings forwardly the-clamped end of the filling is carried forwardly'so as to bring the fillinginto the Zpath of the usual temple thread cutter. I

The present invention is concerned particularly with the means for cl osing' th e fil 1- ing clamping and parting device.

' A housing 25 isirigidly secured to the side of thearm 15 which forms a part of the filling-carrier support 13. v This housing is held-in place by a screw'26 passing through its lowerfiangedportionintothe arm 15 and a fulcrum stud 27 passing through the housing and serewedintothearm=1a Lshaped striker arm 28 ispivotally .fulcrumed on the stud'27 with its 'rearward end located in the housing and its foiwvard and laterally ere tended end 29' projecting over the movable blade :22 of the fillingclamping and parting device when that device is in its rearward operative "position. An adjustable stop in the :form of 'a setsc-rew 30 held in place alock nut '31 extends throu'gh th e top of the housing and-abutszthereariend of the striker arm .28. A' "longitudinally acting helical spring 32 is enclosed in the housing and seated at its lower "end on the housing and at itsaupper zend'in asocket formed in a latrearend of the striker arm 28.. This helical spring 32-t-hus acts yieldin-gly'to hold the rearward end of the striker arm against the stop30. The striker armis thus enabled to yield against the tension of the spring with respectito the support upon the ocurrence of any abnormal resistance. It is not an easy matter to assemble and adjust the filling clamping and parting'device, the shuttle feeler, transferrer, etc. relatively .to each other, and this yielding :feature of the striker arm enables any'inaccuracy in adjustment to be compensated forby the relative yielding oi the striker arm and filling carrier. support in the closing operation of the filling clamping and partingmeans. The closing movement otithe blade'22 is usually limited by a pin 34 projecting laterally trom'the shuttle feeler through an opening '35 -l'1'13li-il0 movable blade. After the movable blade has been closed tocausethe pin are) engage thewall of the opening '35, any further movement might act to'break or shear ofi the pin, but such further movement is pre vented in this case by theyielding ofethe striker-arm.

In order to .securethe opening of the :filling clamping and parting device when it moves .rearwardly to operative position. a

switch. cam mechanism is provided. For

this purpose abracket'armBB secured to the loom frame extends upwardly and forwardly and at its upper. end-is provided with a stud 37 and a stop lug 38;. Theswitch cam is in the form of an inclined flange 89 formed on the rearward endof an arm 40 pivotedon the studBT normallyerestingiby gravity on the lug 38. filling clamping and parting device is pro-.

vided with a laterally projecting pin 4d and the parts are so arranged that when the The movable blade 22-ofthe shuttle feeler swings to'iorward position,

carrying the clampedand-parted filling end. this pin rides beneath the switch cam 39 raising-the arm 40; which drops backxonto the lug-38 after the pinhas passed forward of it, to the position shown in Fig. 1.

When upon the call for filling-replenishment the shuttle :feeler swings rearw'ardly, the pin 41 rides upon the forward -:Eaceot the switch cam and :swings the movahle blade 22 to open position. p

The invention thus provides a simple and efieotive means for securing :the .-desired resultsin which thestriker arm and its connected parts form a sel-f contained structure which may readily be connected toexisting looms. p

Havingthus described my invention, what I claim as new and desire to securebyLetters Patent, is:

1. An automatic filling-replenishing loom comprising a lay, a replenishing magazine for the fresh filling carriers means for transferring a fresh filling carrier from the magazine to the lay, a filling clamping and part ing device movable into position to receive the running filling when the lay is in position for transfer, moved by a fresh filling carrier upon its transfer from the magazine to the lay, a housing secured to the side of the support, a striker arm piv'otally fulcrumed in the housing and thus bodily movable with the support and having its forward end normally projecting over the filling clamping and parting device When the said device is in its rearward operative position, a stop on the housing limiting the downward movement of the striker arm with respect to the support, a longitudinally acting helical spring mounted in the housing and interposed between the housing and the striker a filling carrier support arm and acting yieldingly to hold the striker arm against the stop, the said striker arm thus moving with the support and acting to close the filling clamping and parting device when in operative position but yielding against the action of the spring with respect to the support upon the occurrence of any abnormal resistance. p

2. An automatic filling replenishing loom having the construction defined in claim 1 in which the portion of the striker arm extending into thesupport is provided with ALONZO E. RHoADEs.
