IMPROVEMENT IN CORDERS FOR SEWING- 'MACHINES.

Specification forming part of Letters Patent No. 49.968, dated September 19, 1865.

To all whom it may concern:

Be it known that I, JAMES W. BRADY, of the city and county of Baltimoreaud State of Maryland, have'madc new and useful Improvements in (Jorders for SewingMachines; and I do hereby declare the following to be a full, clear, and exact description of the nature, construction, and operation of the same,

v reference being had to the accompanying drawings, which are made part of this specification,

I To enable one skilled in the art to which my invention appertains to construct and use the same, 1 will proceed to describe it.

A is a bar, to be suitably attached beneath the table of the sewing machine, and supporting the frameB G (J, to which the shank D of the corder is attached. These portions are adjustable on each other in such a manner as to bringthe bent portion of the corder E]? G H I to the required position on the cloth-plate of the machine as The position of the point of discharge a of the cord is adjusted transversely to the motion of the cloth by means of the slotted arm B, which is pnshedin the required direction and secured in position by the set-screw b. The same adjustment within a certain range is secured by the withdrawal or protrusion of the shank D of the corderin the slot cof the frame 0, the required adjustment being made permanent by means of the setscrew d.

The vertical adjustment of the corder on the cloth-plate is attained by means of slipping the slot-ted'frame 0 up or down on the portion B and securing it by the set-screw c. The ad justment horizontally'in'the line' of motion of to height and horizontal the cloth, so as to bring the point a nearer to or more distant from theneedle, is secured by moving the block J in the slot of the bar A and securing it by the set-screw b.

The bar A. is attached to the.under side of the table by means of screws through the screw-holes g g. The corder being placed in position and the cord passed through the eyes attached to the corder, as shown in Figs. 1 and 2, the shirt-bosom is placed, as shown in Fig. 2, in such a. relation to it that while the portion E lies above and smoothes the main fold the portion G lies underneath it and the secondary fold, when the corder, again taking a turn toward the needle, brings the opening a on the portion I over the secondary fold and thrusts the cord into. the angle between the two folds. The cloth being now fed along in the direction of the arrow, the needle stitches the three thicknesses of cloth together, securing the cord in the required position.

The corder is prevented from rotating by the fin h, which traverses in the pper portion of the slot 0. q

In Fig. 4 is illustrated the shape in which I make the corder when attached on'the other side of the cloth-p ate, and which I consider substantially the same, though possessing fewer angles or bends, owing to the locality of its attachment. 7

Having thus described my invention, what I claim therein as new, and desire to secure by Letters Patent, is-

1; The corder E F G H I, substantially as described and represented, and adapted to feed the cord underneath the main fold and intothe angle formed between it and theseconda'ry fold. a

2. The combination of the devices, substantially as described, by which the cordershank is moyed vertically, laterally, or backward and forward, according to the requirements of this work.
