IMPROVEMENT IN SHUTTLES FOR LOOMS.

Specification forming part ofsLetters Patent No. 174,376, dated March 7, 1876; application filed December 1, 1875.

Looms; and do hereby declare the same to be fully described in the following specification,

and represented in the accompanying drawings, of which Figure 1 denotes a longitudinal section of a shuttle provided with my invention, it also showing a bobbin as applied to the spindle of the shuttle. Fig. 2 is a side view of the' spindle. Fig. 3 is a side view of the latch-1ever of said spindle.

My invention is to hold the bobbin firmly on the spindle, while the latter is down with in the body of the shuttle,.the bobbin being easily removed from or applied to such spindie when the latter is in a raised position.

The spindle is shown at A as having its blade 00 semicircular in transverse section, ta-. pering longitudinally, and provided at its outer end with ahead, b. There is pivoted t0 the blade, at its heel c, a locking-lever, B, whose longer arm 0 is tapering, and shaped like the blade a, and also provided with a head, f, like the head b. The shorter arm of the lockinglever has its top beveled, or making an acute angle with the heel of the spindle, while its rear end also makesan acute angle to its top, all being as shown.

When the. spindle is moved down into the bobbin-chamber of the shuttle-body U, the rear arm of the locking-lever will be forced against the stop or part d of the shuttle-body,

whereby such locking-lever will have its longer arm moved away from that of the spindle and within the bobbin D, so as to cause it to be securely held to thespindle, or from flying 0d the spindle, while the .shuttle may be in movement in a loom.

When the Spindle with the bobbin OI] it is spring over them, so as to be operated there by. Although I have pivoted to the spindle a locking-lever, the two do not cross one another, they being arranged side by side, and hinged together at their heads, one head only being pressed on by the spring, and the other being beneath its fellow, and borne against the back-stop d, whereby the longer arm of the locking-lever is forced away from that of the spindle, and the two caused to hold the bobbin thereon. v

What, therefore, I claim as my invention or improvement inthe loom-shuttle is- The lockingdever B, arranged beneath and hinged at its head tothe lever D, in manner and to operate therewith, and with the back, stop d, all substantially as set forth.
