Specification of Letters Patent.

Application filed December 27, 1905. Serial No 293,511.
To a/ZZ whom it may concern.-
Be it known that I, CARL HUBER, engineer, a subject of the-German Emperor, and a resid ent of No. i6 Friedrichstrasse, Berlin, in the Empire of Germany, have invented certain new and useful Improvements in Hydraulic-Pres's Multiplicators, of which the following is a clear, full, and exact description.
This invention relates to a hydraulicpress multiplicator which has for its object to attain in the press-cylinder of a Huber hollow press constructed for high pressure a multiplication of the pressure of, for instance, ive thousand atmospheres to ten thousand to twenty thousand or still more atmospheres in the ordinary pressure-chamber, said pressure being sufficient for ordinary high pressures.
According to this invention the press-l multiplicator 1s so mounted in the high-pressure receiver of the press, whose casing is constructed for the 1highest attainable pressure, that its outer casing is surrounded by the water under pressure of the pressurechamber of thepress. The pressure contained in the main receiver and acting on the large piston surface or area of the pressmultiplicator thus produces a multiple maximum pressure in the inner cylinder of the press-multiplicator and at the same time relieves the outer casing of the inner cylinder.
Referring to the accompanyingr drawings, Figure l shows the arrangement of the multiplicator in a press for making Copper tubes or copper rods, 'and Fig. 2 shows the arrangement of the multiplicator in anembossing-press.
The casing a of the pressure-chamber a of the press shown in Eig. l is constructed in the usual manner of such a thickness that 1t can withstand and the highest attainable pressure-namely, up to seven thousand atmospheres. The water in this pressure-chamber is as is usual in such hydraulic hollow presses, placed under pressure by a piston l), and thus adapted for pressing hollow bodies.
For the purpose of multiplying the pressure of, say, five thousand atmospheres produced in the pressure-chamber a there is providedin the latter the press-multiplicator c, which is provided with a wide bore d and a narrow bore e. The piston f is slidably arranged in the wide bore d, and the piston g, which is connected to the piston f, is sl-idablyT arranged in the narrow bore e. rIhe ratio of the diameters of the pistons f and g is such that the pressure of about five thousand atmospheres bearing on the piston f is multiplied by the piston g in the chamber e to twenty thousand or more atmospheres.
The press-multiplicator c is so arranged in the chamber a that besides the full surface or area of the piston f the total outer surface or area thereof is surrounded by the water under pressure in the chamber a. As this water under pressure forms per se a non-compressible body the casing of the press-multiplicator c cannot be deformed, notwithstanding the comparatively thin casing of the pressmultiplicator c and the high pressure (twenty thousand atmospheres) in the cylinder e, as the surrounding water under pressure of live thousand atmospheres in the chamber a relieves such casing. The upper end of the pressure-chamber e of the pressmultiplicator communicates with a passage 7L, which is located in the end screw c', as well as inthe connecting-pieces and Z. If, for instance, copper, brass, or 'any other medium harld metal is brought into the pressurechamber e and the necessary pressure is produced by means of the piston g, the metal located in the chamber e leaves the same through the matrix L. The cross-section of the passage may be of any desired form.
.According to the constructio'nal forni shown in Fig. 2 the press-multiplicator arrange-d in the pressure-chamber has two pairs of pistons f gf g, which operate axially with respect to each other and einboss the intermediate blank (medal) in the desired form. It is possible by this press-multiplicator to emboss medals of the largest size on both sides in one to two operations.
Having now particularly described and ascertained the nature of this said invention, I declare that what I claim, and wish to secure by Letters Patent, is-
1. In a hydraulic press, the combination of a casing, cylinders within said casing having piston areas of varying diameters, coperative pistonsi'n said cylinders, and means for producing pressure in the casing.
2. In a hydraulic press, the combination of a casing inclosing main and rauxiliary cylinders, tile said cylinders having piston areas of varying diameters, coperative pistons in said cylinders, and means for producing pressure in the casing.
3. In a hydraulic press, the combination of a casing inclosing main and auxiliaryk cylinders, the said cylinders having piston areas l of Varying diameters, coperative pistons in said cylinders, and means for producing pressure in tlie casing and relieving tile pressure in the main and auxiliary cylinders.
4. In a hydraulic press, the combination of a casing inolosing main and auxiliary cylinders, the said cylinders having piston areas of varying diameters, means for producing pressure in tlie casing, and cooperative pistons in said cylinders, the said auxiliary cylinder being totally surrounded by liquid under pressure.
