E. J. MERZ SHUTTLE WINDER Filed March 18, 1925 INVENTOR I ATTORNEY Patented 12 1926.

UNITED STATES ERNEST J. MERZ, 0F CRAN STON, RHODE ISLAND.

SHUTTLE WINDER.

Application filed March 18, 1925. Serial No. 16,550.

To all whom it may concern:

Be it known that I, ERNEST J. Mnnz, a citizen of the United States, residing at Oranston, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Shuttle Winders, of which the following is a specification.

This invention relates to certain new and useful improvements in shuttle winders and the primary object thereof is to provide improved means for holding the shuttle, which means dispenses with the necessity of the provision of holes in the shuttle in the securement thereof to the rotating means, and which also eliminates moving parts.

A further object of the invention is to provide holding means which enables the shuttle to be easily and quickly applied to and removed from the rotating means without the necessity of the manipulation of moving parts, and which means is also of simple and economical construction and capable of holding bobbins of varying sizes.

The invention has still further and other objects and advantages which will be here inafter referred to in connection with the following description.

In the drawings:

Figure 1 is a fragmentary front elevation of my winder engaging a shuttle,

Figure 2, a side elevation of the winder,

showing diagrammatically in broken lines the path of the shuttle,

Figure 3, an enlarged fragmentary section on line 33 of Figure 1, and

Figure 4 is a detail perspective View of the spreader.

In proceeding in accordance with the present invention a handle 1 is employed,

the upper end of which is provided with a rotatable pintle 2 having a crank handle 3 atlixed thereto by means of which the pintle is rotated. The holder for the shuttle is constructed of a strip or body l of spring metal, the ends 5 of which are bent over to form resilient gripping jaws. The jaws 5 confront each other and have their free ends 6 inclined with respect to the body of the strip to facilitate engagement with the shuttle. The holder is rigidly secured centrally of its length to the pintle.

The combined spreader and thread guide consists of an arm formed of a strip of spring metal 7, the upper end of which is curved over to form a circular loop or eye 8 for the thread, the resilient free extremity 9 thereof engaging the arm permitting the thread to be easily moved t-herepast to enter the eye. The lower end of the arm is bent upon itself to form a shank 10 of double thickness, the extremity 11 of the arm being extended outwardly at an angle to form an abutment whiclr engages the inner end 13 of the handle. The part 11 is slotted or notched at 12 to receive the thread, while the shank 10 is received in a cut-out 14 provided therefor in the handle.-

The shuttle S is of the tatting type and is composed of two similar members connected at their centers, the shuttle being usually formed of celluloid and having the ends thereof free of connection so as to be readily susceptible of being spread apart.

In operation the shuttle is secured to the holder by sliding a side thereof into engagement with and between the jaws 5. The thread T is passed through notch 12 being held therein and frictioned by the thumb of the operator, thence through eye 9 and onto the shuttle hub. The shuttle is now rotated and as the ends of same engage the end 8 of the spreader arm, the sides of the shuttle will be spread apart thereby to admit the thread to allow the latter to be wound on the shuttle. By making the jaws 5 of relatively considerable length, shuttles of varying width can be accommodated.

The shuttle may be easily and quickly positioned and removed without the manipulation of nuts or other moving parts.

The resilient character of the strip 4 accommodates this element to any unusual curvature or shape of the engaged shuttle side.-

It will be observed that the arm 7 by virtue of its flexibility offers a minimum resistance to the rotation of the shuttle.

It will be further noted that the member 4. is capable of rotation in either direction.

I claim:

In a shuttle winder, a handle, shuttle rotating means carried thereby, the handle having an abutment and a slot extending thereinto, a flexible arm having one end bent to form a flexible thread-receiving eye, the opposite end of the arm being doubledupon itself and received in the slot and having its extremity turned at an angle to engage the abutment and notched to receive the thread.

In testimony whereof I have aflixed my signature.

- ERNEST J. MERZ.
