LORENZ EGK, OF DUSSELDORF, GERMANY.

CALENDERING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 748,593, dated January 5, 1904.

Application filed July 9, 1903. $erial No. 164,850. (No model.)

movable upper and lower rollers that may be pressed against said middle one, and in particular to means for effecting said pressing action.

My improvements in the means hitherto employed for pressing the rollers against each other consist in certain arrangements and combinations of parts, as are fully described hereinafter; and in order to make myinvention more clear I refer to the accompanying drawings, in which similar letters denote sim i-' lar parts throughout the several views, and in which- Figure 1 is a representation of a calendering-machine with three rollers, of which the upper and the lower are connected with the device constituting my invention. Fig. 2 is a detached view of said device, showing a slightly-modified form of construction. Fig. 3 shows another modification, and Fig. 4 shows a portion of a fourth form.

In each figure the cylinder (1 is shown in vertical section. The stationary bearings m of the middle roller 'm are fixed to the frame 9 of the calendering-machine. The bearings 0 and u of the other two rollers, 0 and u, may glide along suitable guide pieces of said frame. The bearings o are connected by a lever a, fulcrumed at a, with a piston-rod 0,

having a piston 0 located in a cylinder d.

The latter contains another piston,e, the piston-rod e of which is connected by a lever b, fulcrumed at b with the bearings 11.. A pipe Z, terminating into the cylinder d, serves for leading water, compressed air, or steam into said cylinder, so as therebyto press the rollers 0 and 11. against the roller m, and thus upon the fabric or paper passed through between said rollers. The respective material may pass round the roller m-t'. 6., below the roller 0-as well as above the roller u, or two separate breadths may be treated at a time, the one passing through between 0 and m, the other between 11. and m.

The pistons c and e are of equal area, and the pressure exerted upon them is thus of equal intensity. There are also in the example shown no means to vary that pressure. Where the pressure exerted upon the two pistons shall be of diiferent intensity, as is necessary for some kinds of goods, the ar rangement shown in Fig. 2 may be employed. The cylinder (1 consists in this case of two pistons of difierent diameter, the smaller portion containing the piston c, the larger the piston e The pressure exerted upon the roller u, will thus be greater than that exerted upon the roller 0, according to the excess of area of the piston c with respect to the piston c. When the intensity of the pressure exerted'upon the one or the other piston or upon both pistons shall be variable, the arrangements shown in Fig. 3 may be made use of. In this instance the cylinder d is divided by a partition wal1 w into two chambers, oneof which contains the piston c, the other the piston e. The pipe Z is divided into two branches Z Z one of the latter terminating into the one chamber, the. other into the other chamber, of the cylinder.

A three-way cook it allows of conducting the water, steam, or the like either into any one of said chambers or in both at a time, just as the position of the plug of said cock may be. (Compare h and h.) In the form of construction shown the water, 850., may be led away from the upper chamber by means of a pipe 25, so as to relieve the piston c from the pressure when desired or necessary. To prevent a damage by the recoil of the roller 0 on the pressure being relieved, a spring f is inserted between the piston o and the wall w.

A reduction-valve r or the like serves for preventing the water, 850., from exceeding a certain maximum power.

The two branch pipes Z l may be dispensed with if the three-way cock is situated within the wall w, as shown in Fig. 4..

It is self-evident that the pipe connections and the like must in every case suit the requirements of the respective plant. The devices described and their various possible modifications may be used also in connection with calendering-machines having more than three rollers, and two or more of any kind of such machines may be operated from one source of power.

Having now described my invention, what I desire to secure by Letters Patent of the United States is 1. In a calendering-machine having a stationary roller, and above and below the same at least one vertically-movable roller, the combination with said movable rollers, of a cylinder, two pistons located in said cylinder; connections between said pistons and said movable rollers; and means for actuating said pistons, for the purpose as described.

2. In a calendering-machine having a stationary roller, and above and below the same at least one vertically-movable roller, the combination with said movable rollers, of a cylinder, two pistons of different diameters located in said cylinder; connections between said pistons and said movable rollers; and means for actuating said pistons, for the purpose as described.

3. In a calendering-machine, having a sta tionary roller, and above and below the same at least one vertically-movable roller, the combination with said movable rollers, of a cylinder, two pistons located in said cylinder; a wall located between said pistons and dividing said cylinder into two chambers; connections between said pistons and said movable rollers; and means for actuating said pistons, for the purpose as described.

4.. In a calendering-machine having a stationary roller, and above and below the same at least one vertically-movable roller, the combination with said movable rollers, of a cylinder, two pistons located in said cylinder; connections between said pistons and said movable rollers; and means for variably actuating said pistons, for the purpose as described.

5. In a calendering-machine having a stationary roller, and above and below the same at least one verticallymovable roller, the combination with said movable rollers, of a cylinder, two pistons located in said cylinder; connections between said pistons and said movable rollers; and means for variably actuating either of said pistons, for the purpose as described.

6. In a calendering-machine having a stationary roller, and above and below the same at least one verticallymovable roller, the combination with said movablerollers, of a cylinder, two pistons located in said cylinder; connections between said pistons and said movable rollers; and means for leading a fluid under pressure into, and out of, said cylinder, for the purpose as described.

7. In a oalendering-machine having a stationary roller, and above and below the same at least one vertically-movable roller, the combination with said movable rollers, of a cylinder, two pistons located in said cylinder; a wall located between said pistons and dividing said cylinderinto two chambers; connections between said pistons and said movable rollers; pipes for leading a fluid under pressure into said chambers, and means for regulating the flow of said fluid, for the purpose as described.

8. In a calendering-machine a stationary roller, and above and below the same at least one vertically-movable roller, the combination with said movable rollers, of a cylinder, two pistons located in said cylinder; a wall located between said pistons and dividing said cylinder into two chambers; connections between said pistons and said movable rollers, a pipe for leading a fluid under pressure into said chamber, and a three-way cook located in said wall, and adapted to regulate the flow of said fluid from said pipe into the said chambers, for the purpose as described. In witness whereof Ihave hereunto set my hand in presence of two witnesses.
