To all whom 'it may concern:

Be'it known that I, THOMAS Louis JONES, a citizen and resident of Hamburg, in the German Empire, have invented a certain new and useful Compressed-Air Motor, of which the following is a specification.

This invention relates to a compressed air motor and its object is to construct a motor of this kind which runs perfectly quietly and without jerks.

Motors driven by compreshed' air known heretofore which work similar to'a steam-engine are only operated by tlirusts and varymg expansions and thereforjecan only run evenly, if provided with a'fiily-.wheel which consumes part of the power. The new motor, which is shown in the drawing does away with these drawbacks. r*

` Fi e 1 is a side view partly in section and ig.- 2 a Verticalv section drawn to the line 2 2 of Fig. 1.

The motor consists of a casing containing a high' ressure chamber A and a low pressure chamy erv B, arranged side by side and separated by lan imperforate partition E which contains an air tight bearmg D for a motorshaft C. Within the high pressure chamber A the shaft C is provided with\a`=numberof radially dis'posed tubes a and curved tubes b in equal number are also attached to the shat within thelow pressure chamber B. Each tube b is in communication with one of the tubes a by a longitudinal passage c in the shaft C. The tubes b, which are all bent in the same direction as may be clearly gathered from Fig'. 1' are considerably longer than the tubes'uJ so that each pair of tubes a,

b together With their connecting passage c form communicating tubes having arms of unequal lengths. The chamber A which is made air tight where the shafts projects through the outer wall by a stufiing box vD1 is provided with an inlet Z on the top for the compressed air and a water inlet s1 at the bottom. The chamber B has an air-Outlet e at the top and a water Outlet s at the bottom.

On supplying compressed air by the tube Z to the chamber A, which is previously filled with water or some other liquid nearly to the height of the shaft O, the air will also rush into the chamber B` by way of the tubes a, passages c and tubes b, which on account of their curvaturc will` begin to move in the direction of the arrow W, thus turning i the shaft C in the same direction.

Owing to the fact that the tubes a are by such rotation temporarily immersed in the and by the Way of the passages c into the tubes b, through Whicy theh flow out into the chamber B. The quantities ofliquid owing to their greater Weight,` act with greater force on the 'walls of the tubes b than the compressed air, thus increasing the power of the shaft O.

In order to obtain as unifor'm a rotation as possible it is advisable to maintain the level of the water or other liquid in the vessel A invariably at the same height and this is attained by means of a fioat f which at a given height of the liquid causes a valve f to close the inlet 81. The supply may be furnished either by a piston pump or by a centrifugal pump, not shown, mounted on the sha'ft or otherwise in operative connection with the same. This pump may be so arranged that it forces the liquid running out of the chamber B from the pipe s into the pipe 8,1 and from here back into the chamber A. In order to avoid the tubes a and b striking the water with great force, the spaces' between thel tubes may be filled up, so that .disks are formed having radial passages. The pressure of highly compressed air or gas can be utilized to a better advantage by combining two or more motors one behind the other.

Instead of using the apparatus as a motor it may also be used as an air compressor. In this case the shaft O is driven by any suitable motor preferablyin the direction of the arrow WI. The quantities of water rushing through the tubes or passages b by the centrifugal force create a sucking action in the passages c and in the tubes or passages a; thus the air out of the Chamber A is forced into the chamber B and compressed air may be taken from the tube e. The chamber A may be open to the air on top an'd the tube Z removed. Also the pump between the tubes 8 and 81 may be dispensed with and instead of in the chamber A the float valve may be 'arranged in the chamber B.

To obtain a greater pressure than is possible by using one of these'compressors of a certain diameter and with a limited number .of revolutions, several of these eompressors can be combined one behind the other.
