CARL THEODOR SOH'UTZINGER, OF HAMBURG, GERMANY.

HYDRAULIC AIR-COMPRESSING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 508.150, dated November '7, 1893.

Application filed May 13, 1893. Serial No. 474,166- (No model.)

T0 or whom it may concern:

Be it known that I, CARL THEODOR SoHiiTZ- INGER, of Hamburg, in the Empire of Germany, have invented a new and useful Improvement in Hydraulic Air-Compressing Apparatus, of which the following is a specifica- The object of this invention is to provide for the compression of air by an apparatus which shall be automatic in action and require but slight supervision.

An apparatus embodying my invention operates by pressure of water or liquid of any suitable nature and will operate to maintain a pressure of air in a receiver therefor equivalent to the pressure of water to fill said recelver in the first instance or replace air drawn therefrom for any purpose and so maintain constant pressure or tend to restore the pressure diminished by withdrawal of the air to the normal pressure in the said receiver. I Such apparatus will be found suitable among various uses, for the raising of liquids such as beer and being simple in operation and construotion can be attended to so far as needed by any unskilled person.

Figure 1 of the annexed drawings represents a side elevation of the apparatus, and Fig. 2 a front elevation, said views being partly in section on the lines w to Fig. 2 and or m Fig. 1 respectively. Fig. 3 represents a section on line y y Fig. 1, and Fig. 4 is a plan view partly in section of a part of the apparatus.

On a suitable framework r is fixed a horizontal spigot or central stationary shaft 0 which is prevented from revolving and serves as a bearing for a sleeve b surrounding it and adapted to revolve or oscillate thereon; This sleeve carries two radially arranged receivers hereinafter shown.

or other of their extreme positions. Y The comparatively large channel or bore e communicates with the lateral ports 2 and 5 respectively for egress of the water from either of the receivers a a namely that which for the time lies lower than the other. The bore or channel g communicates with the ports 3 and 8 (Fig. 2) and permits the egress of air from that receiver a a, which is highest through the pipe or passageforf' leading to the uppermost part of the respective receiver. Other ports 4 and 6 (Fig. 4) in the spigot lead to the open air for admission of air into that receiver a or a, which at the time lies lowermost as a, in Fig. 2. Corresponding passage- Ways are made in the sleeve b for communication with the receivers 61. a. so that the action is as follows:

Referring to Fig. 2, the receivers are in such position that a rests on one of the rubber or equivalent cushioning stops p-provided one for each of the receivers. Water enters the higher receiver a and rises therein displacing the air compressed by the force of the incoming water and causing it to issue from pipef and port 3 to outlet passage g leading to the air receiver or reservoir. As the receiver a fills with water its gravity is increased and (the gravity of a diminishing as hereinafter shown) the receiver a, will at length overbalance the system and cause itto rock so as to bring down the receiver a onto its cushion p; the water therein empties into port 5 (Fig. 3) to outlet e and air enters at port 6 into pipef to replace the out-flowing water. Meanwhile the receiver a will have become filled with Water through port 7 and the air therein will have become compressed and driven out at port 8 until the system is again overbalanced and reverts to the position shown in Fig. 2, when the Water in a will flow out through port 2 (Fig. 3) to outlet e and air to replace the water will enter through port 4. Ball valves or equivalent devices are used as at h (Fig. 2) to be floated upward when the respective receiver is filled with water and close the pipe f f so as to prevent water from entering such pipe. The height of the cushions p may be regulated so that the tipping of the system may coincide as nearly as possible with the complete charge of the upper vessel with water.

A pressure gage'm is provided in thecompressed air pipe for indication of the pressure.

Failure of action at any time is illustrated simply by the stopping of the apparatus below the normal pressure on dialm due to the water pressure. It may be remedied :by lubricatingthe shaft or spigot c and moving the system back and forth once or twice by hand until it works easily.

\Vhat I claim as my invention is- An apparatus for compressing air, consisting of a stationary horizontal spigot and a loose rocking. sleeve with two attached air and Water receivers mounted in unstable equi librium on said spigot, the said spigot having a pair of water inlet ports for the admission
