PATENT QF IQE,

IMPROVEMENT IN FLUTING-MACHINES.

Specification forming part of Letters Patent No. 169,327, dated November 2, 1875; application filed August 6, I875.

To all whom it may concern:

Be it known that I, HERMANN ALBRECHT, of Philadelphia, Pennsylvania, have invented an Improved Fluting-Machine, of which the following is a specification:

'The objects of my invention are, first, to so construct a fluting-machine that the depression of the upper fluting-roller shall require but a slight effort; and, second, to so construct the frame that there may be below the lower roller and its support a free, open space for the admissionand passage of the fabric. These objects I attain in the manner which I will now proceed to describe, reference being had to the accompanying drawings, in which- Figure 1 is a front View, partly in section,

of my improved crimping or fluting machine; Fig. 2, a vertical section; and Figs. 3, 4, and 5, perspective views of detached portions of the machine.

To the base A of the machine is secured the frame B, composed of the vertical portion a,

and the upper and lower arms I) and b, the latter overhanging the base, so as to permit the free introduction between the said arm and base of the fabric to be crimped. The journal at of the lower crimping-roller D has its inner bearing in the vertical portion a of the frame B, and is provided with a suitable handle, E, the outer bearing of the said roller being on a circular stud or projection, e, on the turned-up end f of the arm b. A frame, H, carries the upper fluting-roller D, the inner journal h of which has its bearing in a projection, z, of the said frame, the outer bearing being on a circular projection, j, forming part of a plate, is, whichis so attached by a set-screw, m, to the outer end of the frame H that it can be readily detached therefrom. From the frame H projects an arm, n, which is hung to a pin, 1), on the upper stationary arm b of the frame B, and to the same pin is hung a lever, I, through the short arm w of which passes a screw, q, for bearing on a spring, J, and forcing the ends ofthe same onto the frame H. When the machine is in use the lever l is locked by a projection on the vertical arm of the bellcrank lever N, which is hung to a pin on the projection 31 of the arm b of the frame. When the upper fluting-roller has to be raised, however, the lever I is unlocked by operating the bell-crank lever, and the arm a: of the said lever I is depressed, and as this arm bears on the outer end of the arm n of the frame H the latter, with the upper fluting-roller and spring J, must be elevated.

It should be understood that when the machine is adjusted for operation the fluted rollers are always in contact with each other; but when the fabric is passed between them the upper roller will yield, as the only obstacle to the rising of the frame is the spring J; hence the pressure on the fabric passed between the rollers will depend solely on the adjustment of this spring by the screw q. When the lever I is unlocked, and its armw depressed, the latter arm, bearing on the upturned end of the arm n ofthe frame H, must elevate the latter, and with it the upper flirting-roller; in other words, while the frame H is under the control of the lever I, the said. frame and its upper fluting-roller are capable of yielding independently of the said lever to an extent dependent upon the thickness of fabric introduced between the rollers, the fabric itself being subjected to a pressure depending upon the adjustment of the spring by the screw. Owing to these peculiarities the depression of the upper roller requires no such effort as in a machine in which the easy manipulation. of the lever for depressing the upper roller is interfered with by the spring.

It will be understood that the fluting-rollers' are, as usual, made hollow for the reception of leasing the said lever, all substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

HEBMANN ALBRECHT.
