TIP SUPPORT POR FILLING REPLRNISHING LOOMS.

Application led June 4,

To all whom it may con-cern:

Be it known that I, DUNCAN M. BAILEY, a citizen of the United States, residing at Fall River, in the county of Bristol and State of Massachusetts, have invented an Improvementvin Tip Supports for Filling Replenishing Looms, of which the following description, in connection withthe accom panying drawings, is a specification, like characters on the drawings representing like parts. f

This invention relates to tip supports for filling replenishing loomswhereby the tip end portions of the filling carriers are supported andV guided into the shuttle chamber during the transferring operation.

In filling replenishing looms of the type wherein a fresh supply of filling is trans- .ferred from the hopper to the shuttle, the base of the filling carrier is engagedby the transferrer while a part of the filling can riertowards' the tip is4 engaged by an arm laterally extended from the transferrer. Looms of this type are usually provided with means to support and guide the tip of the filling carrier as it is transferred to the shuttle, and such tip support is yieldingly held in normal position and gives or yields under the downward pressure of the filling carrier as it is transferred.

It is well known that filling carriers vary in size; that is, the diameter ofthefilling carrier near the tip portion thereof will vary in different sets, so that while the tip support may properly cooperate with one size of -filling carrier to support and guide the tip end portion into its final position in the shuttle chamber, itwill not so support and guide a filling carrier of different size or diameter.

One of the objects of the present invention, therefore, is to yprovide a tipV support inra filling replenishing loom, such that filling carriers or bobbins of dierent sizes or diameters may have their tip portions supportedand guided into proper position in the shuttle chamber before-passing out of the control of the tip support. In'accord'- ance with this general feature of the present invention the tip support is mounted on a fixed' element in' the machine for pivotal movement thereon, and the amplitude ofV such pivotal movement as well as the position about which such movement takes place are changeable in accordance with the 'ing the transferrer and tip described.

' Fig.` 3 is aside elevationshowing'the tip port and guidance of filling carriers of a different` size than those indicated in Figs. 1 and2: and n Fig. 4' is a slightly modified form of means tip support. u V l v Referring to Fig. 1 of the *drawings` the filling carriers are shown 'as mountedl in a rotating feeder or hopper to' successively sition after ay replenishing operation, but the present invention lis not necessarily'restricted to this particular typeofhopper i As shown, the loom frame 1 has mounted mounted for rotative movement the hopper 3., -Thel hopper 3 is mounted for rotative 'movement about the axis 4' and is given ar rotative or step movement to present a filling the present invention associated: therewith;

support adjusted and regulated for the su`p *7' for regulating the initial position offthe move the filling carriers totransferring pothereon the hopper v`Stand 2 in which is carrier to position for transfer after each re- 'Y plenishing operation. The means foreffect- 'ing this movemento'f the hopper 3`forms no essential part!l of the present invention: and may' be of any usual character which, being well understood by those familiar with machines of thistype, need' 'not be here The filling'ca'rriers' 5 are mountedin the' per to thefshuttle by a transferrer 6 which is pivotally mounted on a stud 7 mounted upon the machine frame. Extending downwardly from the hubportion of the transferrer 6 vis the arm 8 to which is pivotally connectedat 9 the dog 10 whichis adapted yto be engaged by the bunter 11 on the lay ingy,the outer or tip end portion of the filling carrier or bobbin 5 during the trans- `ferringxoperation. As thev transferrer 6 is causedto descend to efect the transfer, the head' ,end portion 15l thereof lengages the head portion `of the filling carrier or-vbobbin and l'the down-turned'end 14. ofthe arm 13 engages the tip portion of the-bobbinI whereby theb obbin'.0r/'fillingl carrier is removed v from the hopper and-'placed-,in the chamber Iries a sleeve orl housing 22.- `housing 22fand preferably surrounding the lshaft* 21 `is a spring 23,-onevend of" which is of'thershuttle 16 when the latter isy in position, as indicated in Fig. 1, that is, when Vthef'shuttle i's'in the filling replenisli'ing box andthe lay is about its1 front center'when filling replenishment is to be effected.

Secured inv fixed positionto the stud or deadshaft 7is'a'member vor armi-7 on which isf pivotally n iounted4 thev tip support` 18. The tip support v^18-is preferably formed'as shown and has an end portion 19 which,

lwhen the tip support is4 tilted downwardlyV into dotted' line position, Figs. 1- Aand 3, eX- tends well into the shuttle chamber without engaging the side of the shuttle-itself.

The fixed member 'or arm-.17 has av hub portion 20 through which extends the small sha-ftfor pivotali support 21 having4 the tip support 18- secured' thereto; supportv or shaft 21 extends throughV the hub 20=andI on the inner side thereof car- Within the secured tov the housing at 2liy and the other end-'of which is secu-red to the hub 20, the tension of the spring being such as to normally tend tol turn the tip support 18V ina contraclockwise direction, viewing the presH ent drawing. `By providing the housing v with a'Y series of openings 25 for the reception of they Cotter pin 26,- which alsofpasses throughthe shaft 21, the tensionof the spring: 23 mayv be varied.

Extendingfrom the fixed arm 17 is a lug 27 throughwhich extends-the regulating or adjusting-screw 28 whichmaybe locked in its 'adjusting position by a set nut 29, and

yextending above the end of the adjusting screw 2 S`is the'toe 30 ofthe tip support, the construction being such that under the action ofthe spring 23 the tipsupport will be held normally in position with the toe 0r The pivotal Y stop y30v in engagement with the end .of the regulating or adjusting screw 28.

AThe fixed member or arm 17 as above stated is mounted on the stud'or dead-Shaft 7 and is connected to saidv stud or4 dead shaft in adjusted position by a set screw 31 so' that lwhen the parts are arranged or regulated for filling carriers of a size such as that indicated in Figs. 1 and 2, the tip support will be turned downwardly from its full to its'dotted line position.F ig. 1, during the transfer, and will' vsupport and guide the tip of the fillingrcarrier froml the'hopper to its final position in the shuttle chamber,

at which time; that is, when thev filling can' rier has reached' its finalposition in the i til itis finally positioned in the shuttle.`

lVhen, however, bobbins lor fillingcarriers of adifferent size or'diai-nete-r than those indicated in Figs.v 1 andy 2 are employed, the arc or amplitude of movement of the tip support and guide will not `be suitable.` That is to say, if the bobbins or fillingcarriers are of a smaller diameter, as indicated in Fig. 3, the arc or amplitude of movement of theftip support will fbe such as to release the smaller filling carrier or bobbin during transfer before suchV filling carrier or bobbin` reaches its proper orfinall position in the shuttle chamber. Therefore, theV pres ent invention contemplatesmeans for regulating the arc or amplitude of the pivotal movement of' the tip support and a changeV in the positionV of the .center about which the tip support turns, ino-rder toaccommodate bobbins: or fillingv carriers of different sizes lor diameters.. f

lf it be assumed, for instance, that the tip support has been employed in connection with bobbins or filling carriers such. asre-'presented at in. Figs..1` and 2:and is to be employed iny connection with filling; carriers or bobbins such as 32, Fig. 3, of a different or smaller size or diameteigthe machine attendant will adjust the arc: or amplitude of movement of thetip .support 1 8 byl changing Y the initial positionl of the tip support, sothat it will be: .Close to or in engagement with the A tip end of vthe filling carrier or bobbin, as indicated in-Fig. 3, and willsimultaneously therewith manipulate the adjusting screw 31 to alter,` the positionV ofthe axial center about which the tip support turns, from its normal position, as indicatedV on the .line

. a-b to the secondary position indicated by the line a-o, so that in adapting the tip support for the functional discharge of its purpose in supporting 'and direct-ing filling carriers of different sizes into their final and proper position in the shuttle chamber, the amplitude of movement of the tip support will be changed, and likewise it may be desirable to change the position of the center about which the tip support tur-ns, so that regardless of the size of the filling carriers or bobbins employed, the tip support may be regulated to properly support and guide filling carriers to their final position in the shuttle chamber.

The amplitude of movement of the tip support will be adjusted by thev regulating device or set screw 28, whereas, the position of the center of the tip support will be regulated by the arm 17 and the set screw 31.

InV Fig. 4 a slightly modified form of an adjusting device for the amplitude or arc of movement of the tip support is shown, wherein, instead of employing the set screw 28, the arm 17 has mounted thereon a shaft 33, Fig. 4, on which is secured or formed an eccentric 34 which underlies the toe end 30 of the tip support 18. The end'of the shaft 33 may be screw threaded and have mounted thereon the set nut 35, whereby upon loosening the nut 35, the shaft 33 may be located more or less to position the eccentric 34 as desired under the toe 30 of the tip support, thereby varying its arc or amplitude of movement.

What is claimed is:

l. In a filling replenishing loom, the combination of a hopper for filling carriers, a transferrer to transfer a filling carrier from the hopper to the shuttle, a yieldingly contolled tip support to guide the tip portion of a lling carrier from the hopper to the shuttle, a fixed member on which the tip support is pivotally mounted, an adjustable means for varying the amplitude ofpivotal 'movement of the tip support in accordance with the size of the fillingl carriery to be transferred, and means for varying the position of the pivotal center of the tip supportv that the tip portions of filling carriers ofdifferent sizes may be engaged and guided .by the tip support from the hopper to their final position in the shuttle and then pass out of engagement with the tip support.

3. In a filling replenishing loom, the comt bination of a hopper for filling carriers, a transferrer to transfer a filling carrier to the shuttle, a tip support having 'the free lend thereof downturned to enter and guide the tip of a filling carrier into the shuttle cham* ber, a fixed member on which the tip support is pivotally mounted, means for varying the amplitude of movement of the tip support on said fixed member to accord with the size of the filling carrier to be transferred, and means for varying'the position of the pivotal center of the tip support that it may be engaged with the tip portion of filling carriers of different sizes from the time they leave the hopper until they reach their final position in the shuttle.

In testimony whereof, I have signed my name .to this specification. DUNCAN MONROE BAILEY.
