IMPROVM ENT IN PLAlTlNG-MACHINES.

Specification forming part of Letters Patent l\'o 411,441, dated February 2, 1864.

ing drawings, making part oi' this specification, in whichy Figure l is a side elevation of my improved machine. Fig. 2 is a plan or top view thereof.

Similar letters of reference indicate corresponding parts in the several views.

'The subject of this invention is a machine whereby continuous plaits or tucks of any desir-ed number and width may be produced in linen 'or other material 'for shirtbosoms, skirts, or any other purpose for which they are required; and the invention consists in the combination ot' a pair of feed-rollers with a series ot' folding and guiding plates of peculiar construction, said rollers being either hollow or solid, and designed to be used either hot or cold, with surfaces either plain, grooved, or embossed, all as will behereinafter described.

In order that others skilled in the art to which my invention appertains may be en-v abled to fully understand and use the same, I will proceed to describe its construction and operation.

In the accompanying drawings, A is a frame supporting a bed or table, B, and two parallel rollers, C C', which rollers are adapted to revolve one above the other. The roller C is journaled in suitable bearings in the lower part of the frame A, and the roller O is pressed down thereupon by box-straps D D which are held in positonby set-screws D' D', and allowed to yield in an upward direction to permit the passage of goods between them by spiral springs d d, which encircle said screws, and are secured at their respective ends to the box-straps D and heads ot' the screws D'.

d' cl. represent lubricatingapertures. rlhe rollers are so arranged that their surfaces are brought in close contact with each G' a bent- )late secured thereon in ansuitable manner. The plate Gr may be secured to the table B by screws g g, and the inner edge thereof occupies a position between the plates H H', which are attached to a scroll-guide, L, the latter being secured upon a plate, J. which may be fastened to the table B by screws g g2. The edge ot' the plate H is situated beneath' the plate G, and all the plates are designed to occupy horizontal positions at different levels, as shown in Fig. 3. The scroll-guide is employed to turn the edge of the material, and is adapted for use, in connection with an internal guide, I', for the laying ofcords within the plait. roller G to accommodate the cord and retain the same in proper position as it passes between tlie rollers.

K represents the linen or other material to be plaited.

Operation: Thematerial may be dampedV with either steam or water, it needful, and is introduced between the several plates and within the guide I in the manner shown in Fig. 2. The temporary removal of one of the plates Gr or J will greatly facilitate the introduction of the linen or other material between the plates, and the screws D Dl may be partially withdrawn to more readily permit the insertion ofthe end ot' the piece-to be plaited between the rollers G C. The rotation of the .rollers by the crank F or other suitable means will then serre to draw the material through between the plates and press into permanent shape the folds, plaits, or tucks formed thereby. Continuous plates maybe thus produced from end to end ot' pieces of material of any length, and the plaited goods may be separated into any required length for shirt-bosoms or other purposes.

By varying the number and positions of the plates the width and number of the plaits or folds may be varied as required.

Pivoted disks may, it1 preferred, be employed instead ot' the plates to produce the folds.

The machine maybe made ofsufcient width c c represent grooves formed inthe to produce au entire shirt-bosom at one opera G G H H, scrolLguide I, and feeding and presstion,and,if desired,theroilersean beembossed ing rollers C C, adapted to operate substan to represent; stitching.

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

A machine constructed with folding-plates i tially as herein described.
