JEROME B. SEGOB, OF CHICAGO, ILLINOIS.
IMPROVEMENT IN CHECK-LEVERS FOR SEWING-MACHINES.
Specication forming part of Letters Patent No. 121,966, dated December 19, 1871.
To all whom it may concern:
Be it known that I, JEROME B. SECOR, of Chicago, in the count-y of Cook and State of Illinois, have invented certain new and useful Improvements in GheckLevers for Sewing-Machines, of which the following is a specification, reference being had to the accompanying drawing.
Myinvention consists in the combination of the slotted pin O, the screw S2, the coil spring S3, and the lever B, as hereafter described; the object being to make a simple attachment not liable to be disturbed in its operation, and one in which the tension of spring can be easily and readily regulated.
Figure 1 represents a side elevation of the checklever attached to the sewing-machine, and Fig. 2 a central sectional view through the line x x.
A is that part of a sewing machine, usually called the goose-neck, to which the check-lever is ordinarily attached. B is the check-lever. C is a pin having a slot, S, a shoulder, D, and a head, E, and also a female screw, S1, cut in one end, as shown. S2 is a male screw, which screws into the female screw, as shown, and, in connection with the shoulder, it holds all the parts together. S3 is a coil-spring coiled around the pin C, with one end passing through the slot S, and the other end through the check-lever, as shown in the drawing. The spring acts directly on the check-lever, and when it is desired to change the tension of the spring it is only necessary to turn the pin C, which has a screw-head, and this pin is tightened so as to be kept in any desired position by simply turning the screw S2. The pin and spring are placed in a recess in the gooseneck to protect them from dust.
This is a simple attachment, any part of which can be readily removed and replaced by the operator, and by it the tension is easily regulated.
Having described the construction andoperation of my improvements, what I claim, and desire to secure by Letters Patent, is-
The slotted, headed, and shouldered pin C, screw S2, and spring S3, when arranged within a recess or chamber in a goose-neck of a sewingmachine, and combined with the check-lever B, all constructed as described, and operating as and for the purposes specified.
