CARLOS STEBBINS, OF PIKE, NEW YORK.
IMPROVEMENT IN SEWING-MACHINES.
Specification forming part of Letters Patent No. 126,755, dated May 14, 1872.
Specification describing a new and useful Improvement in Sewing-Machines, invented by CARLOS SrEBBrNs, of Pike, in the county of Wyoming and State of New York.
Figure 1 represents a side view of sewingmachine provided with my improvement. Fig. 2 is a detail side view of the upper-thread regulator, showing it in a position different from that shown in Fig. 1. Fig. 3 is a detail top view; Fig. 4, a side view, and Fig. 5 a longitudinal "section on the line c c, Fig. 4, of my improved shuttle.
Similar letters of reference indicate corresponding parts.
The invention will iirst be described in connection with all that is necessary to a full understanding thereof and then clearly pointed out in the claims.
y A in the drawing represents the sewing-table of the machine. B is the arm which holds the needle` slide, cloth-presser, &c. C is the the driving mechanism. F is a vibrating upperthread controller. It is at d connected with a lever, G, which connects with the driving mechanism, and has at the rear end a projecting pin, e, which plays in an irregular.- shaped slot of a double cam,rH. This cani is made of two pieces, fg, of which the lower, f, is firmly secured to the arm B, while the upper, g, projects from the cloth presser, as shown.
While the lever G is vibrated the threadguide F is also vibrated on its pivot d, the degree'of such oscillation being regulated by the position of the pin e in the slot of the cam H. Now, the more the cloth-presser is raised, the more will the motion of the lever be spent in the elongated middle part of the slot in H, which is upright, and the less will it enter the oblique upper part ot' said slot, wherein it would be moved to slacken the tension. This iarrangement also arrests the pull upon the upper thread while the needle-eye is passing upward through the work, which is accomplished by the falling of the pin g between the f projecting inner points of the plates f g.
rlhe shuttle C has two incisions, h h, through itstop. The same are partly closed from beneath by a plate, t', against the under side of which a spring, j, is bearing. The spring and plate z' are fastened to the shuttle by means of a screw, l, by which the tension of the spring -can be regulated.
The shuttle is threaded by swinging the plate 'i and spring j clear of one slot, h, and
inserting the thread in the other slot, and then swinging it clear of the other slot and threading same, finally bringing all parts into the position shown in Fig. 5, when the plate lwill hold the thread confined with the degree of strength imparted to it by the spring j.
