SPECIFICATION forming part of Letters Patent No. 759,440, dated May 10, 1904.

Application filed June 22, 1903. Serial No. 162,681. (No model.)

To ail whom, it may concern:

Be it known that I, ALFRED R. HERITAGE, a citizen of the United States, residing at Graham, in the county of Alamance and State of North Carolina, have invented a new and useful Loom-Shuttle, of which the following is a specification.

This invention relates to loom-shuttles, and has for its object to provide in a loom-shuttle an improved mechanism for holding the spindle in proper alinement with the side walls of the shuttle and to provide in connection therewith automatic bobbin-holding devices which the upward movement of the spindle will open and release a bobbin supported on the spindle.

In attaining the object above stated I make use of the improved shuttle hereinafter fully described and claimed, and illustrated in the accompanying drawings, forming a part of this specification, in which corresponding parts are designated by the same characters of reference in the several views in which they appear, it being understood that changes may be made in the form and proportions of the elements exhibited without departing from the spirit of the invention or sacrificing any of its advantages.

In the drawings, Figure 1 is a View, chiefly in longitudinal section, showing the spindle in solid lines parallel with the sides of the shuttle and in dotted lines tilted out of parallel position to release the bobbin therefrom. Fig. 2 is a plan view of a portion of the shuttle, showing the spindle partially tilted and showing the action of the cams at the end of the spring plate upon the bobbin -holding catches. Fig. 3 is a plan view of a portion of the shuttle, showing the action of the catches to hold a bobbin on the spindle. Fig. 4 is a detail view in perspective of the spindle and the bobbin-holding catches detached from the shuttle. Fig. 5 is a detail view of the springplate, by which the spindle is held in operative and inoperative position.

Referring to the drawings by reference characters, S designates generally a shuttle constructed in accordance with this invention, comprising the usual wooden body 1, having a central longitudinal opening 2, in which is pivotally mounted a spindle 3, having at the pivoted end thereof a head 4:, on the upper surface of which is formed a cam 5 for engagement with a plate 6, of springsteel, which is mounted on the upper surface of the spindle, near one end thereof andin suitable position to engage with the cam 5. On each side of the head i is provided a spring-catch 7, each of said catches comprising a stem 8, which is securely riveted to the side of the spindle-head, as seen in Fig. 4, and a curved head 9, provided with an inwardly-disposed flange 10, which is adapted to engage with the usual annular notch on the head of a bobbin B. The catches? are so formed that they tend normally to spring inward toward the spindle to engage with the head of a bobbin, and the catches are forced apart when the spindle is swung on its pivot in an upward direction by the engagement of the catches with cam-surfaces 11, formed on the forward margins of a pair of downwardly-disposed lugs 12 at the end of the spring-plate 6, which overlies the head of the spindle.

The spring-plate 6 is mounted in a recess in the upper surface of the shuttle, as shown, and is secured therein by means of a screw 13, which passes through an opening in the plate and engages an opening in block 14, let into the under side of the shuttle. The end of the spring-plate 6 which projects into the main opening 2 of the shuttle is broadened by the formation thereon of the lugs 12, already mentioned, which project laterally on either side of the relatively narrow stem 15, which extends forward from the body of the plate 6. The lugs 12 serve not only to spread the bobbin-catches 7 ,p but also cover and protect the surface of the wood at the end of the opening 2 adjacent to the head of the spindle, and so prevent any splintering of the wood in that vicinity which might injure the warp of the cloth in the weaving process.

The cam 5 on the head of the spindle is so formed that when the spindle is lowered into alinement with the side walls of the shuttle the spring-plate 6 holds it' in that position, and when the spindle is tilted upon its pivot until it reaches the dotted-line position shown in Fig. 1 the spring-plate 6 tends to retain it in that position.

It will be seen from the foregoing description and from an inspection of the drawings that the spring-plate 6 forms means for retaining the spindle in alinement with the side walls of the shuttle when the shuttle is in use, serves to hold the spindle in raised position when it has been tilted upward for the removal of an empty bobbin and the placing of a wound bobbin on the spindle, and also forms means for automatically spreading the bobbin-catches as the spindle is raised and holding them apart as long as the spindle is in inoperative position, thereby greatly facilitating the replacement of empty bobbins with wound ones. It will also be observed that the bobbin-engaging catches in the improved form of shuttle are so constructed that they hold a bobbin firmly, so as to prevent the breakage of the head thereof, and also that they are adapted to engage with and hold securely a bobbin having a broken head if the head has not been entirely broken off.

Having thus described the construction and use of my invention, whatI claim as new, and desire to secure by Letters Patent, is

1. In a loom-shuttle havinga pivoted spin- 3 dle and spring-fingers normally in position to engage a bobbin, a spring-plate adapted to hold said spindle normally in operative position and to spread said bobbin-engaging fingers when said spindle is thrown out of operative position. 1

2. In a loom-shuttle having a pivoted spindle, a cam-lug formed on the head of said spinv bobbin-engaging catches also mounted on the head of said spindle, and a spring-plate engaging said cam-lug to hold said spindle in operative or in inoperative position and having downwardly bent, laterally projecting lugs provided with cam-surfaces to engage and spread said bobbin-engaging catches.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses,

ALFRED R. HERITAGE.
