SPECIFICATION forming part of Letters Patent No. 793,581, dated June 27, 1905.

Application filed February 10, 1905. Serial No. 245,037.

1'0 I'I/H/ whom it may concern' Be it known that I, JAMES F. HA TMAN, a citizen of the United States, residing at Salisbury, in the county of Rowan and State of North Carolina, haveinvented certain new and useful Improvements in Loom-Shuttles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to loom-shuttles, and has for its object the reduction in wear of the spindle upon which the bobbin or quill is supported, and etfective and simple means for securing the bobbin detachably to the spindle; and the invention consists in certain improvements in construction, which will be fully disclosed in the following specification and claim.

In the accompanying drawings, which form part of this specification, Figure 1 represents a longitudinal section, partly in side elevation, of a portion of a loom-shuttle embodying my invention; Fig. 2, a like view of the spindle and the bobbin detached, showing a modification of the spindle; Fig. 3, a like view of the same parts, showing a modification of the means for securing the bobbin on the spindle; Fig. 4, a top plan View of the spindle shown in Fig. 1, and Fig. 5 a like view of the spindle shown in Fig. 2.

Reference being had to the drawings and the designating characters thereon, 1 indicatcsa loom-shuttle, which may be of any preferred form and of any suitable material.

2 indicates the spindle, which may be made in the form shown in Figs. 1 and 4, in which the spindle is provided with a part 3 and a part 4, the latter being of less diameter than the former and having a shoulder 5, and the ,bore 6 of the bobbin 7 is made to conform thereto, or it may be curved on its surface 8 from the rear end to the point thereof, as shown in Figs. 2 and 5, and the bore of the bobbin made to conform thereto.

The spindle is provided with a shank 9, which may be provided with an enlarged part 10, and the shuttle is provided with a socket 11 in one end thereof, into which the shank extends and is secured therein against longitudinal displacement by a transverse pin 12, which extends through the shank and the shuttle, while the spindle is held rigidly and firmly in the shuttle against lateral movement by the shank engaging the wall of the socket. In the shank 9 is an opening 13, (shown in Figs. 1, 2, 4, and 5 in the form of a longitudinal Vertical slot,) in which alatch 14 is pivotally supported on the pin 12 and is provided at one end with a member 15, which engages a groove 16 in the exterior of the rear end of the bobbin, and at the opposite end of the latch is a head 17, under which is a spring 18, resting in a seat 19 in the shank and bearing against the under side of the head to hold the member 15 in engagement with the groove 16in the bobbin, and is thereby secured in position on the spindle.

The bobbin is released by depressing the head 17 which throws the member 15 out of engagement with the groove 16, when the bobbin can be removed for rewinding.

It will be observed that the spindle is short and stout as'compared with spindles in general use in loom-shuttles and is fixed or rig idly supportedin the butt of the shuttle, thereby avoiding the usual wear and tear and loos- -ening effect incident to hinged spindles, which must be turned up out of the shuttle for the insertion of the bobbin.

In Fig. 3 the latch rests in an opening 20, is secured by a transverse pin 21, which, like the pin 12, extends through the shuttle, and the member 22 engages a groove 23 in the interior of the bobbin and is held in engagement therewith by a spring 24, resting in a seat 25, until released by pressure brought to bear upon the head 26.

Having thus fully described my invention, what I claim is- A loom-shuttle provided with a socket at one end, a fixed spindle having a shank integral therewith, extending into said socket and provided with an opening through the shank, In testimony whereof I aflix' my signature in a latch in said opening provided with mempresence of two witnesses. bers projecting forward beyond the spindle JAMES E H M AN on 1ts upper and lower sides, a spring under 5 the upper member, a transverse pin engaging Witnesses:

the spindle, the latch, and the shuttle, and a J. M. MGCOOKLE, bobbin engaged by said latch. J. M. DAVIS.
