GUSTAV J. E IEDEICII, or NEW YO K, N. Y., ASSIGNOR F TWO-THIRDS To HIMSELF AND ONE-THIRD To ALFRED BAKER, TnUsTEEs, on NEW YORK, Y.

L'ooM-sHUTTLE.

a citizen of the United States, residing at ing shuttles. I At the present time there is in extensive the borough of Manhattan, in the city, county, and State of New York, haveinvented certain new and useful Improvements in Loom-Shuttles, of which the following is a specification, reference being had therein to the accompanying drawings, which form a part thereof.

My invention relatesto loom shuttles. and

more particularlyto a type of quick threaduse loom shuttles having an eye in the side wall thereof adjacent one of the bearings out the several'views.

for the cop, it being a common practice in using this type of'shuttle forthe operator to hold the end thereof on one side of the eye and to'suck the thread through the eye.

By means of ashuttle made in accordance with my invention, the operator is enabled to thread the shuttle more quickly than itis possible to thread the type of shuttle above referred to, by merely applying .pressure through a short section of the yarn held taut upon a threading device carried by the side wall of the shuttle adjacent the eye.

By the use of a shuttle made in accordance with my invention'there is not only a sav ing of time in threading, but the. un-

hygienic practic'esnow commonly followed are avoided and injury to the health of the operator by reason of the inhalingof small fibers from the yarn is prevented.

The shuttle is so constructed that the threading mechanism is substantially flush with the outside of the shuttle. and the parts thereof are so arranged as to avoid any I is tendency of sucha disarrangement of parts as would interfere with the continued use-of the shuttle.

' The invention consists primarily in a shuttle having a recess in one side thereof,.said recess having a portion of a shuttle eye in one vertical Wall thereof, a member movably mounted infsaid recess'adapted to-guide the yarn from the top of said recess into said eye-opening and a spring acting upon said member whereby said member may be moved to permit the yarn to enter said eye opening and will be restored to normal after each threading operation; and in such other novel features of construction and combination of parts as are hereinafter set forth and Specification of Letters Patent.

described and more particularly pointed out in the claims hereto appended.

Referring-t0 the drawings Figure l is a plan view of a'portion of a shuttle embodying my invention; 7

Fig. 2 is a perspective view of the mechanism mounted in the side wall of the shuttle 'for forming the eye and permitting the quick In the embodiment of'my invention shown Patented Mar. .11, 1919.

Application filed May 1, i916. Seria1 No.-94,581.

in the drawings, a indicates one end of an ordinary flying, shuttle. -This shuttle has mounted in one side wall thereof adjacent one end 72 of the cop c, a block d forming a part of said sidewall and having therein-a recess e. Extending, transversely through the block all, is a semiscircular opening fforming a portion of the eye of the shuttle. Movably mounted in the recess e is a block 9 adapted to have limited reciprocatory move ment toward andxfrom the wall ofthe recess having the eye opening 7 thereirn suit- 7 the wall of the recess 6 parallel with that wall of said recess having the eye opening 7 therein, this spring being so tensioned as to normally force said member into the proper relation to the wall of the recess having the eye opening f therein, to form a continuous circular eye opening in the mannerabove referredto. g V

The adjoining top edges of theblock cl and member 9 are rounded off as shown at jj so that stresses from the thread section will move the member g against the tension of its spring 'in" a manner to cause said member and the adjoining face of the block (Z to guide the yarn to the eye-opening, said member automatically returning to normal as the yarnenters the eye.

In the form of the invention shown in Figs. 4 and 5, instead of employing a reciprocatory member such as g mounted in an angular opening in the block d, I provide a block cl having a circular opening extending therethrough, said opening having at the periphery thereof a portion 7a of the eyeopening. 'In'closingthe opposite sides of said circular openings are two disks m-m secured in the desired relation to each other by means of a hub 'n. Mounted-upon the hub n is ahelical spring 0 acting upon the sidewall of theblock 05' in a manner to normally turn the said disks to the right, (Fig.

5 The circular opening through the block d is open slightly at the top so as to expose the tops of the disks m m/, the exposed portions of said disks having a notch therein 7 adapted to receive the thread. Hence, a

' downward pressure will cause the said disks to rotate against the tension of the spring 0 and deposit said thread in the eye-opening 70. As the notch 30 comes to position opposite said eye-opening, the thread will leave the notch, thus permitting the spring to re store the disks to their normalposition. The said disks are each provided with a semicircular opening as q adapted to register 7 the opening is to form a circular eyeopen ng n the same manner as heretofore described in connectien' with the form of the invention shown in Figs. 1 to 3. I

In both forms of theinvention shown, the threading attachment may be'made of any desired material and since with the ordinary shuttle, the only alteration necessary to perr nit the adaptation of this threading fitting thereto,isthe cutting of a small section from the wallther'eof, the fitting may be attached to shuttles now in use without material expense. r

In threading shuttles made in accordance with myin'vention, the operator merely takes a short section of the yarn adjacent the end thereof and stretches it sufficiently taut so that exerting a downward pressure against the beveled edges j-jt of the form of the invention shown in Figs. 1 to 3 this pressure will cause the member g torecede sufiiciently from the wall of the block d having the eye opening therein to permit the yarn to slide between the side wall of the block and the face of themovable member. As the yarn enters the eyeopening, the member 9 will return to its for mer position the end of the thread being presented outwardly of the shuttle.

While I have shown the eye opening in the block cl as fleeing a half circle it is apparent that if it be found desirable to make this opening larger or smaller, this change may be made without departing from the spirit and scope of the invention, since it is merely necessary that the portion of the eye extending through the recess to be opened sufficiently to permit the yarn to enter same.

taut section of yarn to the notchin the disks m'-m' with sufiicient pressure to' cause the turning of these disks so that the yarn will be carried and guided between the disks and the adjacent wall of the block d, until the eye opening is is reached. Whereupon, the yarn will passinto said eye opening and the spring a will restore the disks to normal in a manner to bring the portion of the eyeopening 9 therein to register with theeyeopening inthe block d to formacircular eye opening as in the other form of the in vention. In both forms of the invention, the threading of the shuttle may be accomplished substantially instantaneously and the operator is not required to place his or her month about the: eye opening while threading. v c

It is not my intention to limit the invention to the precise details of construction shown in the accompanying drawings, it be-' ing apparent that such may be varied withoutdeparting from the spirit and scope of the invention.
