IMPROVEMENT IN PLAlTlNG-MACHINES.

Specification forming part of Letters Patent No.

179,763, dated July 11, 1876 application led April 21,1876.

Y To all whom it may concern:

Beit known that I, J cHN HAMILTON BROWN, of the city, county, and State of New York, have invented Ycertain new and useful Improvements in Crimping-Machines, of which the following is a specification:

The object ot' my invention is to produce a machine which shallbe simple in action and accuratein operation, for making trimming for ladies wearingapparel; and consists ot' the mechanism hereinafter described.

Figure lis an end view. Fig. 2 is a top view. Fig. 3 is a sectional view. Fig. 4 is a front view. Y

A is the bed plate. B B are the sides ofthe frame. O is the driving-shaft. D is an adjustable eccentric for regulating the feed. E is the crank for operating the crimping-blade b. F is the connecting-rod for conveying motion to the crimping-blade. G is a lever for governing the action oi' the crimp-former on the material. H is a rock-shaft, to which the crimping-blade is attached. I I l are tension bars, through which the material is passed before crimping. J is a shaft, to which two arms, a a., are secured, said arms a a, forming bearings for rock shaft H. K is the top or the feeding-roller. L is the gas-pipe for heating the lower roller X. M is a connecting-rod for conveying motion from the ad,- justable eccentric D to the feed-lever N. O is a pawl for operating the ratchet-wheel P. q is a spring for holding the pawl to the ratchetwheel.- It is an eccentric shaft for detaching the top or feeding roller K from the heated lower roller X. S is the lcvcr for operatii'ig the eccentric shaft R. T T are bars for holding the sides of the frame together. U U are springs, which convey a pressure through the levers V V to the feed-roller K. Yis a spring for producing a friction on the shaft J, for the purpose of allowing the crimping blade to press on the material before any forward action of the crimping-blade takes place. d cl d d are holes in the crank E and. connecting-rod F, for regulating the width of the crimp. eis a shield for protecting the lower roller from gas, soot, or dirt.` fis a set-screw for securing the adjustable eccentric D in position. s is an extension of lever a, against which the lever G strikes, causing the return movement ofthe crimping-blade b. The material to be crimped is passed through'the tension-bars I I l, and between the crimping-blade b-and heated roller X. When motion is given to the driving-shaft O, the crimping-blade b receives ai'orward and back motion from the crank E and connecting-rod F.. In the forward motion the blade I) presscs the material firmly on the roller X, a forward movement of the crimper takes place, making a crimp of thedesired width, which is forced between the rollers X and K, which are held in contact by pressure from the springs U U. The crimp being now formed, the feed-rollers receive inotion from the eccentric D and ratchet-wheel P, carrying the crimp through the rollers. The crimping-blade returns to its starting-point to form another crimp. l

I have now fully described my invention, and the manner of carrying it into effect.

What I claim, and desire to secure by Letters Patent, is-

`1. In a plaiting-machine, the adjustable eccentric D, for operating the `leed mechanism, substantially as described.

2. The combination of the detaching-levers V V, springs U U, and shaft li, substantially as described.

3. The rock-shaft J, passing throughl the roller X, in combination with thc arms a a, and blade-shaft H.
