To all whom it nmy concern:
Be it known that I, OTTO NOLL, 01' Berlin, in the Kingdom of Prussia and German Empire, have invented a new and useful Steam- Motor, of which the following is a specifica tion, reference being had therein to the accompanying drawings, no patents being obtained by me anywhere for this invention save in Germany, No. 41,817, July 3, 1886; in Belgium, No. 73,628, June 26, 1886; in Denmark, No. 857, November 16, 1886; in France, No. 177,630, June 26, 1886; in Great Britain, No. 9,117, July 13, 1886; in Spain, No. 9,285, July let, 1886; in Italy, No. 20,157, June 30, 1886, and N0. 22,482/276, October 20, 1887, and in Norway, No. 190, July 21, 1886.
My invention relates to steam-motors.
In the accompanying design, Figure 1 illustrates a front view of the motor. Fig. 2 is a section through Fig. 1 on the line X Y. Fig. 3 shows the left side view of the motor. Fig. l is a section through Fig. 1, on the line U Z, and illustrates the arrangement of the spiralshaped bent coiled pipe F and the position of the nozzle E. Fig. 5' shows the right side view of the motor. Fig. 6 represents the cocentric and the valve-rod. Figs. 7 to 9 show the nozzle E. Fig. 10 is a longitudinal section through the cylinder of the motor. Fig. 11 is a horizontal section through the cylinder on the section-line o w. Fig. 12 shows a section on the line m a of Fig. 10. Figs. 13 and 11 represent the air-chamber L, with the back-stroke valve (1'. r
A designates a force-pump for supplying water to the engine. It is provided with the back-stroke valve (1', contained in the airchamber L. This force-pump is worked by means of an eccentric from the fly-wheel shaft of the motor. It sucks up a quantity of water by means of the suction-piece S, and forces it, according to the position of the regulatorcoek G, into the pipe B. From the latter the water passes through an adjustable nozzle, E, into the serpentine pipe F. The passageopening of the regulator-cock corresponds with the dimensions of the pump, so that when the regulatoncock C is shut the superfluous water runs off through the back-stroke valve (1 and pipe b.
The back-stroke valve (1 in the air-chainber L is illustrated in Figs. 13 and 14 on a larger scale. In these figures a indicates the suction-valve; b, the delivery-valve; c, the seat of back-stroke valve, and cl the valve 5 5 itself. The latter is connected with the valve rod 70 and the piston e, and moves with the piston e in the box 71, in which the piston e closes air-tight. The spiral spring 9' is inclosed in the space between thepiston e and the upper screws, i, of the box and always presses the back-stroke valve (1 down 011 its seat.
The air-space f of the air-chamber is connected by r, n, and q with the pump-space m, or, rather, with the pipe B. 1 6
The nozzle E is illustrated in detail in Figs.
7 to 9. It consists in the pipe E, the conical point or end of which is cut crosswise and overlapped by a casing, h. Pipe E and casing 72. are provided with corresponding threads. By screwing the casing it onto the pipe E the hole cut in the conical end. 1 of the latter is narrowed by means of the cone 5. By this means the injection can be made as fine as may be desirable. The purpose of 75 this fine injection is to insure the immediate conversion of the water thus injected into steam within said coiled pipe F. This steam is superheated more and more as it approaches the inlet to the cylinder and enters the latter as dry steam. The thread made in the back end of the nozzle E allows of its being screwed onto the support D. The support I) is connected by means of a flange with the serpentine pipe F, which is exposed to the fire direct. The pipe G is screwed onto the coiled pipe F, and the steam is conducted through it into the slide-valve box II and into the steam-cylinder.
The steam cylinder is placed above the furo nace, as is shown in Figs. 10 to 12. In order to heat the cylinder it is enveloped in a mantle or jacket, which, by means of suitable plates arrailged each above the other, is made to form a spiral ascending channel, P P P The fire-gases pass through this channel, play round the cylinder, and communicate to it the heat they contain, and finally escape through pipe T into the chimney. The slide X is regulated by means of valve-rod O',having a yoke formed on one end, and an eccentric, O, turning within said yoke. The latter is represented in Fig. 6. The escape of steam is regulated by the valve 4;, which is operated on by the regulator.
What I claim, and desire to secure by Letters Patent of the United States, is
1. In a steam-motor, the spiral pipe F and the pump for supplying water thereto, in combination with a furnace below said coil, and a cylinder above said coil, into which the steam from the latter is discharged to work the engine or motor, substantially as set forth.
2. In a steam-motor, the spiral pipe F and the pump for supplying water thereto, in combination with a furnace below said spiral pipe, a cylinder supplied with steam by said coil, and a jacket surrounding said cylinder and communicating with said furnace, the said jacket being provided with a-spiral passage through which the products of combustion pass in contact with said cylinder, for the purpose set forth.
In witness whereof I have hereunto set my hand in presence of two witnesses.
OTTO NOLL.
