JOSEPH V. MORTON, OF WINCHESTER, KENTUCKY.
IMPROVEMENT IN NEEDLE-CLAMPS FORSEWING-MACHINES.
Specification forming part of Letters Patent No. 191,362, dated May 29, 1877; application tiled March 19, 1877.
To all whom it may concern:
Be it known that I, JOSEPH V. MORTON, of Winchester, in the county of Clarke and State of Kentucky, have invented a new and Improved Needle-Olamp for Sewin g- Machines, of which the following is a specification Figure 1 is a side elevation of a needle-bar containing my improvements. Fig. 2 is a longitudinal section of the same, looking toward the side of Fig. 1. Fig. 3 is an enlarged transverse section on line at a: in Fig. 2.
Similar letters of reference indicate corresponding parts.
My invention consists in the arrangement of a clamping-bolt, having a head for clamping the needle, and a shank that extends into a transverse hole bored in the lower end of the needle-bar, and is notched to engage a wedge-shaped projection on a rod that extends upward in a hole bored longitudinally through the needle-bar, and is capable of being drawn upward by a milled screw at the top of the needle-bar, so as to draw the clamping-bolt into the bar and clamp the needle.
In the drawing, A-is a needle-bar of a sewing-machine that is bored longitudinally to receive the rods B O.
A transverse hole is bored partly throughthe lower end of the needle-bar to receive the bolt D, having the head E and the slot b, which is widest at its lower side, and is fitted to a wedge-shaped projection, 0, on the lower end of the rod 0.
The rod 0 screws into the rod B, which is of larger diameter, and is provided with a screw, 61, that projects through a slot, 0, in the side of the needle-bar, to prevent it from turning.
F is a screw that engages a threadcut in the upper end of the rod B, and is designed to draw the rods B O upward in the bar. It is provided with a milled head, by which it may be turned.
The operation of clamping the needle consists in placing it under the head E of the bolt D, and turning the screw F until the head of the said bolt is drawn by the action of the wedge 0 against the needle with sufficient force to retain it.
The advantages claimed for my improvement are, that it fastens the needle without the aid of wrenches or screw-driver, and as the hands are separated by the length of the needle-bar, more space is afforded for handling and adjusting the needle.
Having thus described my invention, I
claim as new and desire to secure by Letters Patent The combination of the bolt D, having the slot. 1) and head E, the rod 0, havingv the wedge-shaped projection 0, rod B, and screw F, with the needle-bar A, substantially as herein shown and described.
JOSEPH V. MORTON.
