HYDRAULIC LEATHER, FABRIC, 0R PAPER ROLLING MACBINE Filed June 10 1929 I Patented June 1931 p UNITED STATES I 'JommEs KLEINEwErERs, or" KREFEELD, 6mm, ASSIGNOB; I Friar: Join .nmnwnrmzs serum, or irnnrnnn; enem A rumor GERMAM 'HYDRAULIG LEATHER, Fannie, 0a rar 'm ROLLING Application filed Iune'lO, 1929, Serial No. 369,900, and in Germany December 22; 1 921; 3 I
I have filed an application at this patent in Germany, December 22, 1927 This invention relates to h vdraulicroll ng machines, as for instance calendars,mangling machines and the like, and it has for its object" to make it possible to regulate independently from each other the pressures on the two sides of themachine. This pressure regula-' tion becomes necessary when irregularities occur in a sheet of fabric or paper, so that the travelling, speed has to be regulated. This regulation, can be efiected in levercalenders by adding or removing a heavy mass on the corresponding side of the calender. In purel hydraulically operated rolling machines or stron pressures, in which i 1 cylinder journals are sdbmitted to a common accumulator pressure, such regulation is not. possible, as by such accumulator pressure all cylinder journals are uniformly influenced.
In rolling machines with combined hydraulicand'lever pressure, in which several consecutive levers are connected by couplings, the pressure must with this object in view be -first shut oil, whereupon by shifting the coupling the lever transmission has to be altered, andithen the pressure to be thrown in again.
cumulator communicating with the corresponding pressure cylinder is provided on each side of the machine, so that by changing the pressure of theone or other accumulator quite the same simple manner as in a purely lever calender. Bya control known per se,
According to the invention a separate acthe-desired equalization can be obtained in" j Fig. 2 is a front elevation-of a pressure cylinder.
-()n 'therupri hts a, '6 of the machine two pressure cylinders. c, d are guided shiftable in the direction of pressure. The pressure'cylinders a, d areconnected each by a pipe. 6, f respectively with an accumulator g,- h respectively, the load on which accumulators can "be regulated in a well known manner; Care has evidently tobetak'en, that the connection of the pressure pipe can follow the movement of the pressure cy1inders. Each pressure cylinder has a nut imounted on a screw spindle k, said two screw spindles adapted to be rotated by a common shaft m; through the intermediary of worms 'n, and worm wheels 0. The adjusting of the cylinders c, d can be effected by means of a sprocket wheel 1) and a reached.
A hydraulic rolling machine, comprising in combination a machine frame, pressure cylinders movably guided on said machine frame in the direction of pressure, a nuton chain hanging down so that it can'be easily P corresponding worm, and means for rotating said horizontal shaft. p In testimony whereof I aflix my signature.

the pressure water for both cylinders can j be simultaneously controlled. In order that this arrangement may also be used in connecguided on the machine frame shiftable in the direction of pressure so that they may be adjusted for instance by means -of screw spindles.
Anembodiment of the invention is illus- 'trated by way of example in the accompanying drawingsin which: 7 50 Fig. 1 shows a rolling machine in side elevation,
