IMPRQVEMENT IN TUCK-CREASERS.
Specification forming part of Letters Patent No. 13%,966, dated January 2i, 1873.
To all whom it may concern:
Be it known that I, SYLV'ESTER P. BAB- COOK, of Adrian, in the county of Lenawee and State of Michigan, have invented a new and useful Improvement in Tuck-Oreasers; and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon and being a part of this specification, in which- Figure 1 shows my tuck-creaser in perspective, with the arm raised. Fig. 2 is a side elevation, showing the arm depressed; and Fig. 3 is a detached view of the cam-latch which determines the lateral movement of the nipper.
Similar letters of reference indicate corresponding parts in the several figures.
This invention relates to an improvement in that class of tuck-marking attachments to sewing-machines in which a crease is formed in the fabric on the line on which it is to be subsequently folded, the object of this device being to draw the cloth toward the needle in making the crease and it consists in a latch of .peculiar construction adapted to regulate the throw of the nipper, as will be more fully hereinafter set forth.
In the drawing, A is the base-plate, which is secured to the cloth-plate of the sewingmachine by a thumb-screw passing through the hole a. B is a gage-plate sliding in grooves formed by turning up the edges of the baseplate over the sides of said gage-plate. bis the guide or gage of the fabric to be stitched, and is formed by turning up the front edge of the plate B, which has also a longitudinal slot, 0, through which the thumb-screw passes. O is a pressureplate, projecting laterally from the front end of a long plate, 0, which slides through the gage and a pair of guides on the gage-plate.
The foregoing parts being already known their office requires no explanation.
D is the presscr-arm, being a wire'rod flattened and bent near one end to form a spring, with its extremity bent laterally to p ass through the rear end of the plate 0, which is bent around and secured thereto. To the under side of the presser-arm there is secured a bar, E, which is riveted to it at or about the bend for the spring, and extends toward the front end of the presser-arm and parallel therewith. At the front end of the rod there is secured a vertical plate or standard, I, through a slot, (1, in which the presser-arm projects. From the outer face of the lower end of the standard there projects a guide-pin, b, on which plays the lower extremity of a spring-nipper, G, whose upper end is secured to the outer end of the presser-arm, said nipper being curved, as shown, and perforated near the lower end to receive the pin d. His the tie-piece, through which the needle passes and carries down the presser-arm and its attachment each time the needle-bar descends. The rod E serves as a spring to draw down the standard until the top of its slot 61 meets the presser-arm. In this position the lower point of the nipper will be separated a little from the lower end of the standard, but when the presser-arm is forced down, as soon as the standard strikes the fabric lying on the presser-plate, the continued downward movement of the presser-arm, bending the spring-nipper, forces its free end toward the standard, and the points of both being on the same horizontal plane, the fabric is seized by the point of the nipper which carries it against the standard and squeezes the fold made in it, so that a succession of these movementsgives the necessary fold in the fabric to be tucked. When released the arm rises and the nipper recedes from the standard until both are again in contact with the pressure-plate. To regulate-the distance between the points and quantity of fabric to be embraced between them, on the face of the standard I pivot a latch, I, with a socket, c, at each side of the pivot, the one being deeper than the other, so that to increase the throw of the nipper the deepest socket is turned to receive the presser-arm, and vice versa. J is a cloth-smoother, being a spring wire 'rod coiled around the projecting rear end of the presser-arm, and with its front turned over to form a handle, by which it may be lifted up to introduce the fabric. The smoother lies on the cloth-plate of the sewing-machine at the,
