PATENT EEicEC HENRY DUNPHY, OF NEW YORK, N. Y.

IMPROVEMENT CLOTH-PLAITING MACHINES.

Specication forming part of Letters Patent No. 35,367, dated May 27, 1862.

To all whom it may concern:

Be it known that I, HENRY DUNPHY, of the city, county, and State of New York, have invented .a new and useful Improvement in Machines for Folding Cloth for Bosoms, Plaits,

.Tucks, Snc.; and I do hereby declare the fol- `lowing to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, figures, and letters of refrence thereon, making part of this specificaion.

0f the said drawings, Figure l shows a vertical transverse section of the machine taken through the screw E. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a top view. Fig. 4 isa perspective view of the machine.

the surface ofthe cloth, (out to the desired size,) or by strips or slots of tin, steel, or similar material of the desired width, around which the cloth was folded. The operation as above described is very slow and requires much care to produce perfect work.

The object of my invention is to produce a machine which shall be vastly labor-saving, perfect and rapid in operation, and adapted for folding cloth lengthwise of any length.

To enable others skilled in the art to make and use my invention, I will proceed to describe the construction and operation thereof.

A reprepresents a bed provided with dovetail or other suitable grooves, H H, in which the holders B freely slide. These holders are made with a mortise, F, lengthwise for receiving andllockingthe blades a a a and separators b b b, as shown. To one side of the bed A there is fastened an inclined bar, C. To

this bar there is pivoted at c a bar, D, which is fastened by a pin, G, Fig. 1, .inserted in j the holesd d, Fig. 3. The purpose of this baris for flattening and smoothing the folds after they are drawn through the folders. The folders a a. a.` are a series of metal blades (having rounded edges, so as not to injure the cloth) for the desired number of plaits or folds to be made, and are separated a sufficient distance from each other by means of the pieces b b t. These blades a and pieces b are made to slide freely through the mortise F in the holders B, and, being adjusted to the desired width of folds, are clamped sev curely by the screws E E. (Shown in Figs. l and 2.)

Operation: The operation of the machine is as follows: The blades a a a and pieces b b b being adj usted to the desired width and number of folds, the operator takes the end of a strip of cloth and with a thin piece of metal tucks the cloth into the interstices made by the blades a and pieces b in one of the holders B. The other holder is then brought forward to the first and the two holders fastened to the bed A. Thev cloth will thus be held loosely in folds by the blades c a a matching each other. The operator now takes hold of the end of the cloth thus entered and draws it through the blades lengthwise a short distance, when it is clamped to a rotating cylinder, and a strip of cloth of any number of yards is rapidly drawn through and perfectly folded, ready for the sewing-machine.

The iiattening and smoothing bar D may be heated, for the purpose of better smoothing the material, by a hot ironvplaced upon thev top of the bar D, which may have agtrough or cavity cast therein for its reception, or in any other suitable way.

The great advantages of my folding-machine will'be obvious to all persons familiarwith folding and stitching work on sewingmachines. A whole web (usually forty yards) can be perfectly folded by the use of my machine in less time than a person under ordinary circumstances and with ordinary implements can fold six yards after the cloth has been cut to the proper length for shirtbosoms.

Another important advantage is the stitching the material in long strips, thereby obviating the necessity of stopping or slacking the speed of the sewing-machine'in passing from one piece of material to'another.

I claim as my invention- 1.
