JOB A. DAVIS, WATERTOWN, NEW YORK Letters Patent No. 65,062, dated [May 28, 1867. I
IMPROVEMENT IN SHUTTLES FOR SEWING MACHINES,
TO ALL WHOM IT MAY CONCERN:
Be it known that 1, JOB A. DAVIS, of iVatertown, in the county of Jefferson, and State of New York, have invented certain new and uscf'ul improvements in Shuttles for Sewing Machines; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference heing had to the accompanying drawings, making a part of this specification, in whlch Figure 1 is a side View of the shuttle.
Figure 2, a. top view or plan.
Figure 3, a longitudinal section.
Figure 4, afront end view; and
Figure 5, a bottom view.
Similar letters of reference indicate corresponding parts in the several views.
This invention relates to the manner of regulating the tension of the thread.
To enable others skilled in. the art to which my invention appertains to construct and operate the same, I will proceed to describe my improvement.
Instead of the usual method of passing the thread through several holes in the side of the shuttle, Isubstitute the longitudinal lever-pad s, as shown in figs. 2 and 3, held in place by the pivotp upon the side of the shuttle, and operated by the lateral screw 20 and coil spring 0 inserted in the front end of the shuttle.
The lever-pad is so formed that each end rests against the side of the shuttle, the front end acting as the short end of the lever, so that when the screw is forced against the spring itpresses the long end of the lever against the side of the shuttle, consequently giving the desired tension to the thread. The thread passes from the bobbin up through the slot 6 and is carried over to the slot iin the rear end of the lever-pads, and thence (in the direction of the dotted line in fig. 3) through the hole It in the side of the shuttle. The holes h and i are so placed that the thread passes between the lever-pad and the side of the shuttle, and is subjected to the pressure made by the action of the screw and coil spring upon the lever-pad, and thereby the tension regulated. The pressure upon the-thread is increased or diminished by turning the screw 20. The hole It in the side of the shuttle opposite the slot 2' in the lever-pad is for the purpose of facilitating the threading of the shuttle.
Having thus-described the construction and operation of my improvement, what I claim as my invention, and desire to secure by Letters Patent, isv The lever-pad s, screw w, and coil springs, when constructed and arranged substantially as and for the purposes set forth.
JOB A. DAVIS.
