LOOM-SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 276,019, dated' April 17, 1883.

I Application filed October 11,1882. (No model.)

Manchester, in the county of Hillsborough,

State of New Hampshire, have invented a certain new and useful Improvement in Loom- Shuttles, of which the following is a description sufflciently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming a part of this specification, in Which- Figure 1 is an isometrical perspective view of the shuttle-spindle with its parts detached; and Fig. 2, a vertical longitudinal section of the shuttle, showing the spindle and bobbin in position for use.

Like letters of reference indicate corresponding parts in the different figures of the drawings.

The invention consists of an improved shuttle comprising a shuttle-body, a compound spindle pivoted thereto, a spring for holding said compound spindle in open or closed position, and suitable mean s-such as stops on said shuttle-body and the heel of said compound spindle, respectivelyfor retaining said compound spindle in proper position, said compound spindle being composed of two parts, the main part being flattened on one side facing the auxiliary part, and provided with a hook at its outer end, a curved flange near its heel,and a stop at the outer end of the flattened portion, against which the outer end of the auxiliary part rests when parallel with the main part, and said auxiliary part being flattened on its inner side facing the main part and beveled at its outer end, and provided with a flange at its inner end, against which said spring presses. By this construction the bobbin is prevented from becoming accidentally detached from the shuttle, and may be applied thereto and removed therefrom with facility.

The nature and operation of my improvement will be readily understood by all conversant with such matters from the follo-win g explanation, its extreme simplicity rendering an elaborate description unnecessary.

In the drawings, A represents the shuttlebody, and B the bobbin. The. spindle is a compound spindle, and is composed of a main part, 0, and an auxiliary part, D. The main part 0 is provided with an upwardly-projecting retaining-hook or shoulder, a, near its point, a laterally-projecting arm, (I, at its heel, and a curved lip or flange, in, at its shank, near its heel, the flange extending over the shank of the auxiliary part D, and resting in a corresponding groove, 4), formed therein, when the two parts of the spindle are joined. The auxiliary part D is somewhat shorter than the main part 0, and the top part of its shank is provided with a laterally-projecting flange,

x, which extends over the level or straight top a of the shank of the main part0 when in the shuttle-body A. The inner side of the main part 0 is flattened, as seen at f, and provided with an inclined shoulder or stop, 1', the inner side of the auxiliary part D being correspondingly flattened, and its end 9 inclined to correspond with the ineline of the stop 1'. Each part of the spindle is provided in its shank with a pivot-hole, i, and, when united in the shuttle, the main and auxiliary parts are conjointly pivoted or journaled on the pin z,whieh extends laterally through the shuttle-body in the usual manner. The shuttle is also provided with a stop or pin, 2, and with the usual spindle-spring, E, the inner end of which rests on the upper side of the flange :0, forward of the pin 2, The lower side of the flange z is upwardly inclined from its rear end to its front end, 0, as shown in dotted lines, Fig. 1, so as to allow the forward end of the auxiliary part D to be depressed below the axial line of the main part (J. When the compound spindle is in the shuttle the spring E presses the forward end of the flange mqdown upon the straight part a of the shank of the main part 0, as shown in Fig. 2, and the end 9 of the auxiliary part D will be forced against the side of the spindle-hole in the bobbin B, thereby causing the top of the bobbin to engage the hook at and securely hold the bobbin on the spindle. When the spindle is turned up or out of the shuttle-body, as shown by the dotted lines in Fig. 2, the end a of the flange xcrosses its center of motion, orpasses a vertical line drawn through the center of the pin 2, the forward end of the spring E entering the curve in the flange m, and pressing on the front edge, e,

of the flange w of the auxiliary part D, outside of said vertical line, thereby operating to bring said auxiliary part into parallelism with the main part 0, whereit is arrested by its incliued end g coming in contact with the stop 0", thus enabling the bobbin B to be removed from or placed on the spindle, as the case may be, in a manner which will be readily understood without a more explicit description. The arm d strikes the stop or pin it and prevents the spindle from falling below its proper level or position in the shuttle-body when the same is in use, while the flange m serves as a support on which the base of the bobbin rests when in position on the spindle.

Having thus explained my improvement, what I claim is-- A shuttle consisting of a shuttle-body, a

compound spindle pivoted thereto, a spring for holding said compound spindle in open or 20 closed position, and means for retaining said compound spindle in proper position when closed, said compound spindle being composed of a main part, 0, and anauxiliary part, D, said main part having a flattened side, f, a 25 stop, 1', a book, a, at its outer end, and a curved flange, m, near its heel, and said auxiliary part being flattened on its inner side, and provided with an inclined end, g, and a flange, :0, upon which said spring presses, substantially 0 as described.
