LOOM-SHUTTIJE.

Specification of Letters Patent.

Patented Feb. as, rain.

Application filed October 3, 1914. Serial No. 864,717.

To all whom it may concern Be it known that l, ll-lnnson W. HAKEs, a citizen of the United States, residing at Millbury, in the county of Worcester and State of Massachusetts, have invented a new and useful Loom-Shuttle, of which the following is a specification.

This invention relates to a loom shuttle and particularly to -improved devices for holding a weft carrier therein.

l have shown my improvements embodied in a shuttle of the type used in weft-replenishing automatic looms, in which the fresh weft-carrier is inserted from above and the empty carrier is forced downwardly through and out of the shuttle. In this type or shuttle, the weft-carrier is common gripped between the resilient ]EtWS of a .holder secured in the body of the shuttle,

the jaws extending forwardly on each side of the o ening in the shuttle.

it is t e principal object of my invention to provide improved means for securing the holder in the shuttle. 4 Another object is to provide improved and stronger devices for gu ing the butt of ly with respect to the holding jaws.

My invention further consists in certain devices, arrangements, and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

A preferred form of my invention is shown in the drawings in which- Figure 1 is a top plan view of a portion of a shuttle with my improvements embodied therein; Fig. 2 is a partial sectional view taken-substantially along the line 2-2 in Fig. 1; Fig. 3 is a perspective view of the weft-carrier holder; Fig. 4 is a vertical sectional view taken along the line lsl in .Fig. 1; Fig. 5 is a sectional view of the holder and the securing devices therefor taken along the line 5-5 in Fig. 2; Fig. 6 is a perspective view of a modified form of securing device, andFig. 7 is a sectional view taken along the line 7-7 in Fig. 6.

Referring to the drawings, the shuttle body is indicated at 10 and is provided with an opening 11' extending vertically therethrough. The weft-carrier 12 may be of any usual type and is provided with rings 13 adapted to engage the forwardly-extending jaws of the resilient holder 14. This holder,- as clearlyshown in Fig. '3, may be formed a single piece of sheet material dotted lines in Fig. 1,

bent into the form shown and tempered or otherwise treated to secure the necessary resilience. At its rear end the sides of the holder are contracted and an opening 15 on tends transversely therethrough.

The holder 14: is secured in the shuttle body by a pair of securing members 16 and 17. These members are formed as rights and lofts, but are otherwise identical. Each member consists essentially of a vertical web 18, the two webs being positioned between the two parts-of the holder 14-. when the device is assembled (Figs. 1 and 5). At their upper and lower edges the webs 18 are provided with laterally extending integral flanges 19 and 20, these flanges being received in horizontal slots or recesses in the shuttle body as clearly shown in Fig. 4:. At their forward ends the members 16 and 17 are also provided-with inclined integral flanges 21. The flanges 21 serve to stiffen and reinforce the members 16 and 17 and also guide the butt of the weft caring jaws whenever such movement becomes necessary. The members 16 and 17 are c0mmonly formed by dies from single pieces of sheet metal, and are provided with holes 22 extending horizontally through their webs 18 and corresponding in position to'the holes 15 in the holder have been assembled in the shuttle body, they are prevented from longitudinal displacement therein by the stud 23 shown in and extending horizontally through the openings 15 and 22.

Having thus described the construction of my new weft-carrier holding device, it will be seen that I have provided an exceedingly strong and rigid device for bold ing a weft-carrier, the holder 14 and the members 16 and 17 being each formed of a single piece'of sheet material and the members 16 and '17 being reinforced by integral flanges upon'the upper, lower and front portions thereof.

In the modified form shown in Figs. 6 and 7 I have provided additional means for preventing displacement of the members 16 and 17 relative to each other, said means comprising an integral hooloshaped lug 2% upon the member 17 adapted to extend through an opening 25 in the web 18 of the member 16. The lug 2 1 is rearwardlv bent to closely embrace the web 18, thereby se-- curing the member 16 and 17 firmly t0- gether.

14:. After the parts Edit displacement in any direction. It should i also be noted that angular movement of the holder M with reference to the members 16 and i7 is entirely prevented by the integral upper and lower flanges, while .the inclined flanges 21 provide an exceedingly rigid structure to withstand the blows occasioned by ,the insertion of a displaced weft-carrier.

improved construction thus embodies simplicity and rigidity. to an unusual degree and is, n1oreo,ver, very easily and cheaply manufactured. v

Having thus described my invention .it will be evident that changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope thereof as set forth in the claims, and 1 do not wish to be otherwise limited to the details herein disclosed.

What I claim .is:- 1. A loom shuttle comprising a shuttle body, a weft-carrier holder provided with .a

pair odf holding jaws, and means to rigidly secure said holder in said body, said means comprising a pair of members adapted to be inserted between the sides of said holder and having upper and lower flanges integrally formed ,thereon and closely embracsaid holder.

2. A lo'om shuttle comprising a shuttle body, a weft-carrier holder provided with a pair of holding jaws, and means ,to rigidly secure said holder in said body, said means comprising a .pair of members adapted to -be inserted between the sides of said holder and having upper and lower :flanges integrally formed thereon and closely embracing said holder, and a stud extending. later- .ally through said body, said members, and said holder and preyenting relative dis-. placement thereof.

3. A loom shuttle comprising a shuttle body, a wefit carrier ,holder provided with a pair of holding jaws, and means to rigidly securesaid holder "in said body, said means comprislng' a .pair of members adapted .to be inserted between the sides of said holder, and having upper, lowerand guiding flanges integrally formed thereon.

4. A loom shuttle comprising a shuttle body, a weft-carrier holder provided with .a pair .of holding jaws, and means to rigidly secure said holder in said body, said holder having a U'-shaped rear portion positioned.

parallel and adjacent to a vertical web portion of said securing means and closely en- W shington; D. '0."

gaging said portion on either side thereof, and said securing means having upper and lower flanges formed integral with said web portion between which flanges said holder is vertically confined.

5. A loom shuttle comprisinga shuttle body, a yrett-carrier holder provided with a pair of holding jaws, and means to rigidly secure said holder in said body, said means comprising a pair of members adapted to be inserted between the sides of said holder and having upper and lower flanges integrally formed thereon and closely; emb.rac-.

:6. A, loom Shuttle comprising a shuttle body, a weft-carrier holder provided with a pair of holding jaws, and means to rigidly secure said holder in said body, said means comprising right and left-hand members,

"each having an upri ht web surrounded except at the rear en with an integral outturned .flange, portions of said flange being efl'eetive to retain said holder in the shuttle body, and the remaining portion being .efiective to guide the weft-carrier longitudinally I with l tference to the holding jaws.-

7. A loom shuttle comprising a shuttle body, a weft-carrier holder provided with a pair of holding jaws, and means to rigidly secure said holder in said body, said means comprising a pair of members adapted to be inserted between the sides of said {holder and having upper and lower flanges grally formed thereon, and a stud extending laterally throu h said body, said members, and said hole-r and preventing relative displacement thereof, said-members also having additional means to secure them against relative displacement.
