IMPROVEMENT IN. SEWING-MACHINE SHUTTLES.
Specification forming part of Letters Patent No. 190,925, dated May 15,1877; application filed January 31, 1877.
To all whom it may concern.-
Be it known that I, ROSWELL H. ST. JOHN, of Springfield, in the county of Clarke and State of Ohio, have invented certain new and useful Improvements in SewingMachineShuttles. of which the following is a specification:
My improvement consists in providing the latch of a sewing-machine shuttle with a hinge plate located in an excavation in the shuttletoe, and adjustable by means of a set-screw, so as to permit said hinge to be raised or lowered to regulate the pressure of the latch upon the thread.
In the accompanying drawings, Figure 1 is a top view of a shuttle, to which my improvement is applied. Fig. 2 is a rear view thereof, showing the latch secured against the side of the shuttle-case by its heelpiece and setscrew. Fig. 3 is a front view. showing the latch turned up on its hinge-plate. Fig. 4: is a vertical longitudinal section on the line 4 4, Fig. 1, showing" the hinge-plate raised in its excavation. Fig. 5 is a transverse section of the forward end of the shuttle on the line 5 5, Fig. 1. Fig. 6 is a perspective view, the latch with its hinge plate and heel piece being shown detached from the shuttle-case. Fig. 7 is a perspective view, showing a position that the latch can assume on its hinge-plate.
A may represent ahollow shuttle case or body, having a suitable bobbin, B. The case is slotted at I for the passage of the thread to an orifice, J, having its sides beveled to prevent the cutting of the thread.
K is a pin or stud, around which the thread is passed. The pin K enters an orifice, L. The converging forward end M of the case is depressed or elliptical in cross-section, and provided with lateral projection N to prevent turning. This is the construction of shuttle to which I prefer to apply my improvement to show the best mode of embodying my invention.
D is a latch hinged to an adjustable hingeplate, E, adapted to be raised or lowered by means of a set-screw, G, located in an excavation, F, in the forward end of the shuttle-case. The rear end of the latch may be hinged to a heel-piece, H, forming a cap to the bobbin-receptacle.
The position of the hinge-plate E admits of the adjustment of the tension while the shuttle is in the machine.
Having thus described my invention, the following is what I claim as new and desire to secure by Letters Patent- The combination, with a shuttle-ease having an excavation, F, of the latch D, having a hinge-plate, E, adjustable by a set-screw, G, within said excavation.
ROSWELL H. ST. JOHN.
