JAMES C. SEHGESON, OF PHILADELPHIA, PENNSYLVANIA.

LOOM-SHUTTLE.

SPECIFICATION forming pari: of Letters Patent N0. 539,238, dated May* 14, 1895.

Application filed May l, 1893. Serial No. 472,512- (No model.)

To all whom it may concern! Be it known that I, JAMES C. SERGEsoN, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Loom-Shuttles, which improvement is fully set forth in the following speciiication and accompanying drawings.

My invention consists of a shuttle having a catch plate for engagement with the bobbin, formed with an angular `and tapering opening, and a screw which is provided with an angular and tapering head, said plate having on its inner face aboss which is continuous' of the wall thereof, and'having its opening coinciding with that of the plate, whereby the screw is prevented from rotating itself loose, it having a broad bearing on said plate, and its hold ou the body is firm and.secure without the employment of a nut for such purpose.

Figure l represents a perspective View of the inner face of the bobbin catch-plate of a shuttle embodyingmy invention. Fig. 2 represents a longitudinal section of a portion of the shuttle embodying my invention.

Similar letters of reference indicate corresponding parts in the two figures.

Referring to the drawings:` Aldesignates the body of a shuttle which exceptingtheY features of my invention, is of ordinary construction.

B designates the catch or catch plate which is connected with the part B of the body of the shuttle, and has at one end a nose C for engagement with an annular groove on the head of the bobbin D, whereby the latter is held in operative position, the other end of said catch plate being pressed outwardly by the spring E, which bears against said catch, and the opposite spindle-holding. plate F on the heel ends' thereof, said plate VE exerting pressure on the pivoted head G of the spindle.

The plate F is adapted to bear upon one face of the spindle head to hold the spindle in proper alignment in the shuttle, and upon another face of the head when the spindle is raised to hold it in position to change the bobbin. l

H designates the bolt or screw which con nects the catch plate with the body of the Shuttle, the same having an angular head J,

the latter freely occupying a counter-sunk opening K in said plate, whereby the latter is permitted to rock or oscillate lightly on said head as the bobbin engageswith and disengages from the nose C. The walls of the opening K are extended inwardly, forming the boss L, whose opening is continuous of said opening J, and whose wall is both angular4 and tapering, like a truncated pyramid. The head of the screw coincides in its angle and taper with the walls of said opening and boss, and occupies the openings of both the plate and boss, whereby it has an increased holding surface on the catch plate, and the material of said catch around said opening K is vastly p 'strengthened at a place where the plate is subjected to considerable strain, the screw being also prevented from rotating in reverse direction, as its head is controlled by the wall of the opening K and the boss L.

When the plate B is forced inwardly against the spring E, the head J of the screw H is uncovered, when the same may be engaged by a suitable key and rotated to remove the screw H, and consequently said plate, the same provision existing when saidplate is to be restored to position, the head being caused to register with the opening K, the plate then being let go, whereby the wall of said opening and the boss L again embrace the head of the screw. Theplate E has a boss similar to that of the plate'B, and the screw E is formed with an angular-head similar to the screw H.

'Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

Ashuttle body provided with the bobbincatch and spindle-holding plates, each formed with a boss having an opening of angular and tapering Shape, secu ring screws having angular and tapering heads which occupy .the bosses of said plates and on which'said plates are adapted to oscillate, and a single spring bearing against the heel ends of said plates, the parts being combined substantially as described.

JAMES C. SERGESON.
