UNITED STATES CHARLES A. RIoHARDson, or MANSFIELD, MASSACHUSETTS.

' Loon-SHUTTLE COVER.

Application filed March 8, 1924. Serial No. 697,857.

To all whom it may concern:

Be it known that I, CHARLEs A. RICHARD- SON, a citizen of the United States, residing at Mansfield, in the county of Bristol and State of Massachusetts, have invented new and useful Improvements in Loom-Shuttle Covers, of which the following is a specification.

This invention relates chiefly to shuttles used in carpet and rug looms, the yarn-containing chamber of the shuttle being closed at one side of the shuttle to confine a loose cop or coiled body of yarn or thread, by a cover composed of an elongated metal strip having a hinge socket at one end engaged With a pintle in the shuttle body to form a hinge connection, permitting the cover to swing to and from its operative position. The socket is an integral part of the cover and is formed by bending or rolling one end portion of the cover.

The shocks or jars attending the stoppage of the shuttle at the opposite ends of its throw in many cases cause crystallization of the metal forming the socket wall, and cause breakage of said wall, resulting in separation of the socket from the pintle, and displacement of the cover from the shuttle, often with disastrous results.

The object of my invention is to provide a socket which is free from this objection.

I attain this object by the improved socket construction hereinafter described and claimed.

Of the accompanying drawings forming a part of this specification;-

Figure 1 is a sectional view of a carpetloom shuttle having a cover, the socket of which embodies the invention.

Figure 2 is a section on line 22 of Figure 1.

Figure 3 is a side view of the cover look ing toward the inner side thereof, a portion being broken away.

Figure 4 is a fragmentary side view showing one end portion of the cover before the socket is formed.

Figure 5 is a section on line 55 of Figure 4.

Figure 6 is a fragmentary side view showing one end portion of the cover after a part of the socket-forming operation has been performed.

Figure 7 is a section on line 7'7 of Fig- 55 ure 6.

Figure 8 is a section on line 8-8 of Figure 3. p v

Figure 9 is a section on line 99 of Figure 3.

Figures 10 and 11 are side views, showing aportion of the cover andillustrating a modification.

The same reference characters indicate the cover 14 is a strip cut from a sheet of steel of suitable thickness.

In carrying out my invention I provide one end of the shuttle with an integral socket, adapted to embrace and turn on the pintle 15, and composed of a body portion 17 and introverted end portions 18, increasing the thickness of portions of the socket Wall. The introverted portions are connected with the body portion by necks 19 (Figure 9).

One end portion of the metal strip forming the cover, as first cut from a sheet, may be formed as shown by Figure 4, this por tion including longitudinal ears 20 at opposite edges of the cover. Before forming the socket the ears are bent inward against one side of the cover as shown by Figures 6 and I 7, the metal, being suitably heated to permit the bending operation, without cracking the necks 19, which connect the ears with the body portion of the cover. The portion which includes the ears is then bent or rolled to form the body portion 17 and the introverted end portions 18 of the socket, said introverted portions being rolled extensions of the cars 20.

It will be seen that in the socket, portions of the cut edges formed by the operation of cutting the cover from a sheet are at the inner ends of the introverted portions 18, and not at the ends of the socket. Fracture due to crystallization is liable to start at a cut edge and to progress therefrom, and is not liable to start at either of the necks 19,

the surfaces of said necks being portions of the condensed and hardened surface of the original plate. Owing to this fact and to the increased thickness provided by the introverted portions 18, the socket is free from liability to be fractured.

Instead of providing the cover with ears 20, formed as shown by Figure 4:, I may form one end of the cover as indicated by dotted lines in Figure 10, and bend its edge portions over as shown by full lines, thus forming tapering ears 20 the wider ends of which are rolled with the body of the cover to form the socket as indicated by Figure 10.

I claim:

1. A shuttle cover composed of an elongated metal strip, having atone end an integral hinge socket formed by rolling an end portion of the strip, and adapted to turn on a pintle in the shuttle body said socket having integral introverted portions increasing the thickness of the ends of the socket wall.

2. A shuttle cover composed of an elongated metal strip having portions of its opposite longitudinal edges bent over upon the body of the strip to form ears at one end thereof, the said end and .ears being rolled to form a hinge socket having introverted portions increasingthe thickness of the ends of the socket, and necks forming the socket ends.

In testimony whereof I have afiixed my signature.

CHARLES A. RICHARDSON.
