IMPROVEMENT IN LOOM-SHUTTLES.

Specification forming part of Letters Patent No. 150,240, dated April 28, 1874 application ii-led February 14, 1874.

To all whom it may concern:

' State of Maine, have invented a new and useful Improvement in Loom-Shuttle; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

This invention consist-s in providing the shuttle, upon each side of the space designed for the shank of the spindle, with a vertical groove, adapted to receive and hold the end of the transverse pin which secures the spindle in place, the object being to permit the spindles to be readily removed from and replaced in the shuttle without injury to the shuttle or spindle, by means of which the difriculties incidental to the removal of the spindle in the -old shuttle are entirely obviated, the removal ofthe transverse pin in the old shuttle causing its hold upon the wood to be lesscned, so that it was liable to project and cut the reed. A

In the drawin gs, Figure l represents a perspective view of a shuttle having my improvement applied thereto; Fig. 2, partial views enlarged; Fig. 8, a central sectional elevation 5 Fig. 4, a plan vie-w, and Fig. 5 a perspective view of the spindle detached.

To enable others skilled in the art to make and use my invention, I will now proceed to describe fully the construction of the same and the manner of using it.

A represents a shuttle, which may be constructed generally in the usual wellknown manner, being provided with the usual space a for the shank of the spindle, and the recess al for the securing-spring, which covers the spindle-shank. It is further provided, however, upon each side or" the space designed for the spindle-shank, with a vertical groove cut down from above, or up from below, a suitable distance into the body of the shuttle, as shown. a2 a2 represent metal pieces, preferably placed in these grooves, which, for convenience in insertion, may be circular in their exterior outlines, and tapering in form from top to bottom, as shown. B represents the spindle, constructed in the usual manner, with the head b, having the transverse orifice for the securing-pin b. The vertical groove in the shuttle and the transverse securing pin are adapted to each other, so that when the spindle is placed in the shuttle the metal pieces ofthe grooves will furnish proper bearings for the pin. C represents the spring, which covers the shank ofthe spindle, and secures the same from displacement, it being removably attached to the shuttle by means of the screw c, in the usual well-known manner.

If the spindle is let into the shuttle from the lower side, the vertical groove must, of course, be extended from that side.

By means of the described construction, the shuttles are adapted to have their spindles removed for any purpose without injury; and any known kind of spindle may be inserted without changing, in any respect, the construction ofthe shuttle.

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

'Ihe shuttle provided with grooves, as described, when combined with the spindle having a shortened transverse pin and a spindlesecuring device, substantially as described.

This specification signed and witnessed this 10th day of February, 1874.
