IMPRVMENT lh! SHUTTLE-CHECKS FOR LOti.

Specification forming part of Letters Patent No. SSASQR, dated December il, 1879..

from rebounding too far when it has reached.

the terminus ot' its line ot' travel, and so as to produce no friction or hindrance to prevent the shuttle from moving off freely and promptly on its return the instant the propelling` force is applied to it. My invention consists in the application ot' springs with catches upon them to drop int-o slots or notches in the top ofthe shuttle, as and for the purposes hereinafter specified.

In the drawing, Figure lis a front view with a portion of the outer parts ou the left removed, exhibiting the shuttle and other parts; and Fig. 2, top view, in which the shuttle is represented as at the other or right-hand end of the hatten.

Let-ter A, the hatten, consisting of the ordinary parts and such as I have added; B, the shuttle with notches b b, one at each end C, picker-block Vwhich propels the shuttle D, a spring lying above the shuttle, attached to the end block ot' the hatten, and provided with catch m and bend o, operating as hereinafter described; E, a small rod attached to block C, extendin g forward and turning across at right angles and passing under the spring D, (see Fig. 2 F, abar extending across the hatten from right to left, as may be seen in Figs. l and 2; g, small staples reaching down in front of the passing shuttle, and operating to prevent it from flying out in front; h, a piece at one end of the hatten which swings out, as in Fig. 2, to allow the introduction and removal of the shuttle; t', a pin to retain the piece h in position, (see Fig. l 5) J,`the vibrating frame which moves the block G back and forth, and thus propels the shuttle.

Supposing the shuttle situated as shown in Fig. 1, the frame J is now moved, and when it rea-ches the position shown in dott-ed lines the rodE on block C will raise the spring D, and the block will strike the shuttle and send it on its way, guided in front by the staples g, while the cross-bar F prevents its rising upward and it enters the opposite box just as the pin E ot' the opposite block rea-ches the bend o in the spring D on that side, ailowing this spring to tall and bring the catch m into one ot' the slots b on the shuttle, to prevent its rebounding too far. These springs at each end will thus rise and fall, engage the shuttle when in its box, and release it when the propelling force is applied. The wires g are used in the form of staples in order to have sut'- ticient stability. The wires are very small so as to otter no resistance to the warp passing between them.

By observing Fig. 2 it will appear that the notch b at one end is on one side of theshuttle and at the other end on the opposite side. This is so that the springs may not catch against the shoulder ot' the notch when enter ing the box and passing under said spring.

A recessed shuttle, B b b, in combination with the springs D, actuating-rods E, and propellingblocks C, constructed and arranged substantially as and tor the. purpose speciiied.

In testimony whereof I have signed my name to this specification in the presence ct' two subscribing witnesses.
