MPROVEMENT IN SHUTTLE FOR LOOMS.

TO ALL TO WHOM THESE PRESENTS SHALL COME:

Be it known that I, SILAS E. CHASE, of Boston, in the county of Sull'olk, and State of Massachusetts, have invented a new and useful Improvement in Weavers Shuttles; and do hereby declare the following, to be a-full, clear, and exact description thereof, due referencev being had to the accompanying drawings, making part'of this specification, and in which-- Figure 1 is a longitudinal section of a shuttle provided with myinvention.

Figure 2 is an under side view, and

Figure 3 a side elevation ofthe bobbin-holder as separatedV from the shuttle.

The principal object sought in making this invention has been to simplify the construction, and, as a consequence, reduce the cost of manufacture of a shuttle, at the same time producing one capable of performing its required Work as effectively as if not better than others in use, besides being more durable or lasting.

The invcntion consists in pivoting or applying the bobbin-carrier or spindle to a movable base or plug inserted witbina hole bored longitudinally within the body of the shuttle, and leading out of its bobbin-chamber, substantially as hereinafter explained.

In the drawings accompanying this specification, A denotes the hody'of theshuttle, made in the ordinary form of weavers shuttles, lits bobbin-receiving chamber being shown at I1. i

In carrying out iny present invention, I bore a cylindrical hole, c, within one end ofthe shuttle, and longitudinally and centrally of its axis, this hole c communicating with the bobbin-chamber The bobbin-carrier or spindle is shown at cl as having its head'e pivoted to Athe inner end of a plug,f, and turning within a recess formed therein, the diameter o' the plugf being such as to tightly fill the hole e.

A plate-spring, t, bent into the form of a yoke, is extended about the plug f, and upon opposite sides of and so as to bear upon the spindle-head e, and serves to retain such spindle and the bobbin in alignment with the axis of the shuttle, as Well as tol/permit of the necessary elevation of the point of the spindle, for thc purpose 'of either removing from or supplying thereto a bobbin.

The catch for holding the bobbin in its proper relation to the spindle is shown at g.

From the above description, it will be seen that the only labor required to apply the bobbin-spindle and its appurtenances to the shuttle is to bore the hole c within the body of the shuttle, and insert the plugf therein t0 the proper distance, the plug being securely fixed in position Within the hole by a pin passing through it and thegshuttle.

In addition to the advantages resulting from the ease and expedition with which the bobbin-carrier may be applied to Athe shuttle is the further advantage of saving the bulkof the ends ofthe shuttle nearly entire, as it does not become necessary to cut into it, as in the ordinary mode of applying the spindle,vthus making the shuttle much more durable, and being productiveo't` other advantages which will manifest themselves to practical shuttle-makers. l

claim the combination, with the body of the shuttle, ot' `the plug or base' f, and the bobbin-spindle, with its appurtenances, hinged to said base, substantially in the manner and for the purposes herein shown and set forth.

SILAS E. CHASE.
