Specification of Letters Patent.

Patented Nov. 26, 1912.

Application filed larch 5, 1910. Serial No. 547,422.

To all whom it may concern:

Be it known that I, LEWIS HALLooK NASH, engineer, a citizen of the United States of America, and a resident of South Norwalk, county of Fairfield, and State of Connecticut, have invented certain new and useful Improvements in Turbo-Displacement Enines, of which the following is a specication, illustrated by the accompanying drawings.

My invention is directed to improvements in motive power and consists in certain novel features of construction and operation, by which an elastic fluid, as steam or compressed air, is caused to give motive power to a device.

I- have shown in forms of structures embodying my tion and in order that persons skilled in the art may be able to practise my invention, the features which. constitute my improvement will be described in the following specification and particularly pointed out inthe claims.

In its principle of operation my invention partakes of the nature of an impact or; turbine engine and also of a displacement'structure and I have therefore called my device a turbo-displacement engine.

I will now describe the drawings which show several forms of structures having my im rovement, in which: Y

igure 1 represents a longitudinal section Fig. 2 is a section on thg line 2, 2 ofFig. 1, looking in the direction of the arrow. Fig. 3 is a Fig. 1, looking in the opposite direction. Fig. 4 is a view similar to Fig. 2, with the rotating propeller in place, showing the operation 0 the device. Fig. 5 is a view of the rotor. .Fig. 6 is a modified form of case chamber. Figs. 7, 8 9, 10 and 11 are views of another modification.

which form division inven- 1 to 4.-A. is a case .chiimbers Ia,

\ tion shown at i,

posite end of the cylinder is provided with a head C which has an inlet passage g, and is provided with two parts h, h leading into the interior of the chamber.

Referring to Figs. 4 and 5: It will be seen that the wheel D is of cylindrical form,

divided into interior chambers by blades d walls separating it into interior chambers. Each chamber is supplied with guide blades d and orts d in each end of the chamber communicate at the proper time with the head ports previously referred to. In operation, thecase chamber is-filledwith a liquid E tive fluid. The rotor D is mounted on a shaft F and the sides of the rotor make joint forming contact with the heads of the closure. I a

Referring to Fig. 4: Assuming that the device is in rotation and that air or steam under pressure is admitted into the structure through the pipe g and the ports 72., h, the pressure of 'the steam or compressed air will force the water out of the chambers i, i into the exterior passage 0'. This water will be driven under pressure to the orifices a? in the case walls, and the water will shoot in as a jet, strike in upon the blades d in the chambers k, is, driving the wheel in the direction of the arrow. It will thus be seen that the chambers i, i are discharging and that the chambers k, k are receiving the liquid, while the chambers m, m are empty and the chambers Z, Z are filled;

The cycle of operations is-as follows Supposing a chamber as 1, shown inFig. 4, the inlet ports h, h are about in the position to open communid of the rotor the chambers Z just cation through the ports which communicate with and the pressure of the steam or 'n to drive the liquid out of the chamber Z into the surrounding passage 41 and also by its continued pressure the liquid will be driven throu h the 'et orifices d into the and t is effect will increase as the wheel advances farther into the posii, when, the port being full flow will be passing out of open, the entire are in the position i, z.

It will also be noticed that the wheel. is double-acting and that the liquid is escaping from opposite sides of thewheel, which tends to form abalance and prevents strain upon the shaft device is therefore transferred from a chamber under presexhaust.

sure through orifices or passages formed by the case and caused to reenter another chamber, during which operation it exerts force as upon a turbine structure to produce power, while the gases are exp closure, one wall of which consists of a liquid piston and which liquid piston isdriven out by the pressure of said gas. The driving effect however, is due to the impact of the liquid upon the turbine structure and the operation of the engine is therefore what I have termed a turbo-displacement engine. The centrifugal force of the revolving liquid causes it to take a position substantially concentric to the rotation of the wheel and thereby separates the heavier from the lighter fluid.

Referring now to Fig. 6, itwill be seen that a similar structure is shown, in'which t e passages are subdivided so that there are two passages on each side of the engine. The operation of this form of device difl'ers slightly from that already described in that the first passage, asfor instance, a, a receives theescaping liquid from the wheel under the highest pressure as it escapes from the chambers d, d, and this liquid passing through the passage a", enters the wheel again in the chamber d which is open to the hen the chamber reaches the position d 01 the liquid is expelled through the passages a, a and enters into the chambers d, ti, and the effect of this division of the chambers is that the gases can be expanded undera lower pressure in the chambers d, and a greater amount of power can be recovered than in the form previous-lydescribed. It will readily be seen that the pluralit the egree of expansion is whatever is de: sired. The operation of the device will be readily understood from the description of Figs. 1 to '5, with the differences stated.

It will thus be seen that in my improved engine I make use of a liquid as a means of transmitting the power from a motive fluid of passages could be increased until m are passing across .the to a moving liquid and then take the Iorce of the moving liquid upon a turbine structure to develop'power. In the figures previously described the case passages have been formed exterior to the wheel chamber, but I may form a passage bet-ween the peri hery of the wheel and the case chamber 0 such size and dimensions as to cause a jet action in a similar way, and Figs. 7, 8, 9, 10' and show views of such modified structure. Referring now to Figs. 7,8, 9, 10 and 11, it will be seen that the case chamber shown in Fig. 7 is a section taken upon the

line

7, 7 of Fig. -8.

Fig. 10 shows an end view of the rotor; and Fig. 11 shows a section through the center and illustrates the shape of the reaction blade and the entrance and discharge ports.

In Fig. 9 the case chamber is shown with the wheel removed so that the inlet and outlet ports are readily understood.

The case 6 is provided with the supply passage 7 and the discharge passage 8. The

case 6 is closed upon the end with the cyl-' ich are provided with.

the case camber filled with liquid to the desired point. To

prevent the liquid from escaping with the exhaust, the receiving chamber 16 is constructed in the outlet passage into which the exhaust from the ports may whirl about and discharge the liquid before the gaseous portions pass exhaust pipe. I

The wheel 12 is mounted on the shaft 13 and operated. in bearings so as to make a Joint with one side of thecase, while upon the other side a space is left between the wheel and the case Which forms a jet passage for. the water. The wheel is provided with arms 14 which are curved at their outer ends so as to form .reaction surfaces to receive the impact of of the wheel, coact with the ports haust of the working fluid.

Fig. 8 shows the wheel and the case in one position of its operation in order to show the action of the parts. It will be seen that the port 10 '(shown in dotted lines) is in communication with the passages leading to the wheel spaces 3 a, and 0, while the exhaust port 11 is in communication with the wheel spaces 8, t, u, o and w. p v
