IMPROVEMENT IN PLAITINGQMACHINES.

Specification forming part of Letters Patent N0. 97.7221, dated December 7, 1869.

To all whom t may concern:

Be it known that I, SIMON STERNs, of New York, in the county of New York and State of New York,` have invented certain new and useful Improvements in Blaiting-Machines; and I do hereby declarethat the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The nature of my invention consists in the construction and general arrangement of a machine for making ruffles, as will be hereinafter fully set forth. 1

In order to enable `others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction-and operation, referring to the `annexed drawings, in which- Figure 1 is a longitudinal vertical section, and Fig.Y 2 is a plan View, of my machina A represents the bed of the machine, on which, at a suitable distance apart, are placed vtwo standards, B B. `These lstandards are slotted vertically from the top downward for a suitable distance, and contain in the bottom of said slots journal-boxes C C, in which a shaft, D, has its bearings. On the center of this shaft is placed aroller, E, of any desired width, having a series of teeth along its outer circumference extending acrossits entire width, Th@ teethon the/roller E are cut so as to-form very acute angles, as seen in Fig. l.

On top of the journal-boxes G G,- in the slots on the standards B B, are placed blocks F F, on Jrop of which are other journal-boxes, G G, providing bearings for the shaft I-I, which thus is placed above and parallel with the shaftD above mentioned. The shaft I-I is also in its center provided with a roller, I, of the same size as the lower roller, E, and having the same number of teeth; but these latter teeth do not form such acute angles as those on the lower roller. y Thetwo rollers E and I gear with cach other, and the .upper roller is pressed down upon the lower by means of set screws a a, which pass through bars b b, covering the upper ends of the slotted standards B B. The

set-screws 4a ct bear upon spring-plates d d,

placed on the top of the boxes Gr G, andby er thick or thin, to pass between them, at the same time as the spring-plates d d give the upper roller, I, the necessary elasticity.

Upon one end of the shaft D, outside of the standard B, is keyed a large cog-wheel, J, which receives its motion from a pinion, K, upon the end of the drivingshaft L. The shaft L has its bearings in suitable journalboxes on two inclined arms, M M', extending l from the standards B B, and the shaft is turned by a crank. Upon the other end ofthe shaft D is a cog-wheel, which gears with a similar wheel upon the end of the shaft I-I, and thus the necessary rotary motion is communicated to the rollers E and L. 'p

Between guides on the inner sides of the armsM Mis placed a plate, N, having such inclination as to come,when forced downward, directly on the under side of the teeth on the lower roller, E, pressing the fabric in under said teeth. This movement of the plate N is accomplished by means of two double cams, O O, mounted upon the drivingshaft L. The cams O O and the gearing above mentioned for revolving the rollers E and I are so gaged or arranged that the plate N will be forced downward under each and every tooth of the roller E in succession, two springs, e e, attached t0 said plate, throwing it up away `from the roller the instant the cams have ceased to opcrate. Y

Upon a cross-bar connecting the two standards B B at the top is pivoted a lever, P, the frontend of which is curved downward and forward, as shown in Fig. l, andis acted upon by a double cam, R, mounted upon the center ofthe drivinglshaft L.

At the rear end of the lever B is a vertical rod, S, to the lower end of which is secured the foot T, whose under side is beveled to correspond with the incline of the tableV,which is secured to the standards B B, and across which the rufiie has to pass after coming out from between the rollers vE and I.

The cam R, during each revolution of the main shaft L, raises the foot or hamm er T twice. and allows it to fall downsuddenly upon the ruffle, to press it into theproper shape for sewing in the usual manner.

The working of the machine is very simple.
