LOQM-SHUTTLE AND FILLING-CARRIER omens-on.

[retested Dec. 15, 1908.

Applicationfiled July 1a, 1908. Serial No. 443,862.

To all whom it may concern:

Be it known that I, WILLrAi/r PARK-EB STRAW, a citizen of the United States, and

resident of Manchester, county of Hillsboro,

State of New Hampshire, have invented an Improvement in Loom-Shuttles and Filing Carriers Therefor, of which the following (16' scription, in connection with the accompanying drawing, is a specification, like letters on the drawing representing like parts. I

This invention relates more particularly to looms rovided with means to effect automatica y ,a chanqe in the operation of the loombeione the ill in the active shuttleis completely exhausted, such looms being usually I {termed feeler :loorns because, of the operation of a device which intermittingly enters the shuttle and feels the filling therein.

The Chang-in the operation of the :loom may he stoppage, or it may he Jan-automatic replenishment of the filling in the active shuttle, bothioperations bein well known all the or conceal it until a predetermined amount u of the'filling is woven .ofi. Thereupon the that if the fi art. Various forms of provided with a longitudinal recess or slot over ,whaoh the filling 151 so wound as .to cover feeling device is permitted to .enter the recess or slot, and the desired ohange in the operation of the loom isefieoted automatically. It Will be ap arentto those skilled in the art llin -carrieris not angularly positioned Within the shuttle so .as to bring the recess or slot" directly opposite the feeler. the

latter will-hot operate properly when the determined filling exhaustion is reached.

in automatic filling-replenishing looms of the type illustrated in United States Patent No. 529,940, granted November 27, 1894, to Northrop, the filling-carriers are transferred automatically from a feeder or hopper to the running shuttle, and there is at times a tendency of the filling-carrier to turn during transfer. As a result, after it has been inserted in the shuttle the recessor slot in the barrel will not be directly opposite the feeleropenin Y in the side wall of the shuttle,, .;and hence t e feeler when it passes through such opening cannot operateproperly at the required time.

The present invention has for its "hbj'ect the production of means whereby a fillingcarrier of the ty e referred tois always properly positioned in the shuttle, and the inven} g-carriers have been used n such teeler looms, among others one in which the harrel of the filling-carrier as,

tion is shown arranged for use in connection with an automatic filling-replenishing loom of the before mentioned Northrop? type; I v The novel features of the invention miillho, fully described in the following specification and particularly pointedout the claims annexed thereto. I

shuttle and a fillingecarnier embodying sine; form of theresent inyention, ;the filling-ear; rier being s own asin position to be trans- -view of the portion of the shuttle illustrated- Fig. 1,, with the base andadj scent portion of thefilling-carrier in position therein indicated by dotted lines; Fig. 3 s s-a longitudinal sectional detail-on the line 3-3, Fig. 2

.Fig. 4 is :a transverse sectionon "the lines- 1, Fig. -1, looking toward the lefit, showingiailso a portion of the-filling feeder or hopper.

The filling-carrier ,or bobbin co rises la base 1 provided with asenies ofiann ar projections or rings 2, loi wel'l-known structure, and. abarrel 3 which is shown in Fig. 1 es; vided with a longitudinal recess, preferah ya slot 4 extended directly through thehmrnel at a part thereof to properly cooperate with the feeler, not shown and which is wellllr-nown in the art. Herein the'basel is shown as Gil- Figure 1 is a sideelev'ation.oiafpor tionlciia ferred while a part of the nearer wallof the shuttle is broken out; Fig. 2 is a top plan slabbed oil to present two 0- posite and parallel flat faces 5, located on t e same sides of the filling-carrier as rare the o enings of the slot 4, the faces being :loeate between the; series of rings and the outerendof the base.

It wlllhe understood (that in practioezthe filling is so Wound as to cover the slot 4 until woven oli to a redetermined extent, to permit the feeler evice to enter the slot, hence the importance-oi properlypositioning thefilling carrier in the shuttle.

The shuttle in its main characteristics is of well known construction, .the body 6 having" an opening 7 for the rec'e tion of the filling: carrier, and at one end 0 such opening are" located usual springwjaws 8 havin their inner faces grooved at 9 to receive t eringsZ and hold the same'when the filling-carrier is transferred to the shuttle from the feeder.

An incllned guide 10 is located between the:: basesof the jaws, to direct the filling-cards? longitudinally; at the time it is inserted in th shuttle so that the-grooved jaws 8 may properly cooperate with the rings 2.

Referringyto Fig. 4 a ortion of the feeder is-shown, viz: t e inner plate whic ion int

' of the filling-carrier in the shuttle is effecte( sustains thebases of the filling-carriers, and

said plate 11' is shown provided with periphslightly during transfer the shuttle has'been provided with means to correct such angular movement and to insure the POSltlOIllIlg of the slot 4 directly op osite the -feeler-open-- ing 14 in the side wal of the shuttle, Figs. 1 and 4. To this end the shuttle is provided with two upright metallic guides 15, divergmg from a common stem or base 16, Fig. 3, secured between the jaw bases in any suits able manner, as by a stud 17, the guides being located within the jaws and in parallelism with each other at their free ends and at sucha distance apart that the faces 5 of the base of the filling-carrier will snugly enter between them, see Fig. 2. When the base 1 is so positioned between the guides'the latter positively retain it from any angular displacement and insure the proper ositioning of the slot 4 with relation to the ff; ing 1 of the shuttle. The upper edges of the guides are inclined and form cam surfaces 18, to cooperate with the faces 5 and turn the filling-carrier on its axis into proper angular position should it be turned in its passage from the filling-feeder to the shuttle during transfer. That is, if the faces 5 are not prolperly presented they will be engaged by t e inclined edges 18 of the guides and the fillingcarrier will be turned on its axis,'by such engagemenhas the rings 2 are brought into cooperative relation with the jaws 8.

It will be seen that the angular positionin and maintained by means separate from the holding jaws; the latter'holdingthe filling- I carrier in the shuttle and positioning it longitudinally but having no control over its angular position. i

Having fully described my invention, what eler-open- I claim as new and desire to secure by Letters Patent is z 1. The combination, with a filling-carrier having a longitudinally'slot'ted barrel and a base provided with opposite, parallel, flat faces on the same sides as the openings of the slot of a shuttle having an o ening inits side wall, jaws to engage and he dthe filling-carrier, and means to ooop 'fsfie with the opposite flat faces of the base ofsaidfilling-carrier and insure its position in" the shuttle with the openings of the slot in the barrel opposite the opening in the shuttle wallf v 2. The combination,witlr a shuttle having holding jaws, and OPPOSil'IGlY lOOZtlJGd p081- tioning members having parallel engaging portions, of a filling-carrier 'having-itsbase provided with opposite arallel faces and with means to be engage and held by said jaws, the parallel engaging portions of the positioning members engaging the opposite facesvon the base and cooperating therewith angularly position the same in theshuttle,.

the inclined edges of the guides assisting in turning the filling-carrier, when necessary, to bring the flat faces into position between the guides;

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
