Specification forming part of Letters Patent No. 172,966, dated February 1, 1876; application filed V December 28, 1875.

To all whom it may concern:

Be it known that we, ALFRED G. CANER, of Tottenville, county of Richmond and State of New York, and ELIZABETH SLoAN,"of the city, county, and State of New York, have iny vented a new and Improved Plaiting Attachy rial is fed to the plaiting-edge and to the sewing mechanism, in combination with stops which are attached to-and work in conjunction with the presser-foot of a sewing-machine. The plaiting-knife receives reciprocating motion from 011e of the shafts of the sewing-machine, and its motion is so timed that each plait, when formed, is stitched by the action of the sewing mechanism. The guide of the..

plaiting-knife can be adjusted for knives of different width, and the throw of said knife can be changed for plaits of more or less depth.

In the drawing, the letter A designates the guide-plate of theplaiting-knifeB. Said guideplate is intended to be fastened to the clothplate C ot' a sewing-machine, and it is provided with lip a, which rests against the edge of said cloth-plate so that it can be conveniently and tirmly secured by a single set-screw. On the plate A are secured the grooved guides b b', between which moves the plaiting-knife B, and one of said guides is tted on V-shaped ways c, so that it can be adjusted for knives ot' more or less width. The plaiting-knife B is provided with a slot, d, through which the material is passed to the plaiting-edge e. A reciprocating motion is imparted to thev plaiting-knife, by means of a T-shaped bar, D, which is secured to said knife, and which is provided with a slot, f, through which passes a screw or pin,

g, that is secured in a wheel, E. This wheel is furnished with several sockets at different distances from its center', so that, by changing the screw or pin g from one socket to another,

the throw of the plaitingknife can be adjusted according to the desired depth of the plaits to be produced. The wheel E ismounted on a vertical shaft, h, which has its bearings in a standard, F, secured to the tableor any other part of the sewing-machine in such a position that the wheel E will mesh into a pinion,-G, mounted on one of the shaftsof the sewingmachine. In the example shown inthe drawing said pinion is secured to an extension of the main shaft of the sewing mechanism, but

it is obvious that motion mayr be imparted to the wheel E by any other suitable means. The standard F is adjustable toward and from the plaiting-knife, so that if the throw of said knife is increased its position can be so regulated that it will n'ot'come in contact with the needleof thel sewing-machine. The plaiting-knife 'works in conjunction with stops i t', which are adjustable on a bar, j, that is intendedto be secured to the presser-foot of the sewing-machine, asshown. The position of these stops dependsfupon the width of the material to be plaited, and they are situated on opposite sid es of the presser-foot. The motion of the plaitin g-knife is so timed thatthe same moves back while the material is fed toward the needle by the feed mechanism of the sewing mechanism,"

and, as soon as the feed motion has been completed thejmaterial is firmly retained by the stops i t, and then the plaiting-knife moves for- A ward and produces the plait, and then the needle descends and stitches the plate.

Our plaiting attachment can be so adjusted that the plaits formed are stitched in the middle of their length, or near one edge. For this .purposethe plaiting-knifeis provided with several Jsets of holes, o ne set in the middle and two near its edges, and both the stops i i1 are made adjustable on their supporting-ba-rj.

By this arrangement materials of different v width'can be formed into plaits of various depth with great rapidity.

By giving the plaiting-knife an oblique edge I .SLOAN OF NEW 2.
