IMPERIAL

PATENT OFFICE.

To explain how this machine works, let the movement of the piston and the crank in four parts 1, 2, 3, 4, Fig. 21, divided.

During the first part of 1 to 2, the piston consisting of the propulsion piston D ¹ and the larger suction piston Z> ² connected to it is driven outwards by the ignition and explosion of the compressed mixture of air and gas in the combustion chamber C, described later, whereby in An air-diluted space is created for cylinder B ^{1 until the piston has reached point 2.} The lower openings in the cylinder A are now free and the products of combustion escape through them and through the channel J ¹ , through the slit / ² and the channels / 'of the slide J into the lateral channels F ¹ and through them into the chamber F.

. With the further movement of the piston from point 3 to 4 or with the beginning of the retrograde movement, slide J moves into position Fig. 11, cylinder A communicates with cylinder B through J ^{1, 2} , / 'and _ / ^2, so that the rest of the combustion products escape from A and the same final voltage is established in front of and behind the piston Z>'. Through the valve W and the channel W ¹ , by means of the returning piston D ^2, the overpressure prevailing in the cylinder B is eliminated by forcing the combustion gases out of B ¹ .

During this part of the piston movement, fresh explosive mixture flows into the emptied working cylinder A , the air passing through the tube b into the hollow space a of the slide, while the gas flows into the same through the cock c; the explosion mixture formed in this way passes through channel d into cylinder A.

This inflow lasts until the piston has arrived at point 4, at which point the connection between A and B ceases, in that channel Jf ^{1 is closed off} by the backward movement of piston D ^x .

The compression of the mixture that has flowed in begins during part 4 to 1 of the rear Piston movement.

If the piston has reached point 1 or at the extreme end of the return line, the mixture in cylinder A is ignited by an explosion of an explosion mixture trapped in ignition chamber h which precedes the main explosion, which increases the power of the pilot flame.

This ignition chamber h is attached to the valve body cover M and is, depending on the movement of the slide L, through an upper one

Slot A ^{1 of} this slide with the space A in connection, whereby the filling of the chamber with explosive mixture takes place.

The ignition takes place in that the ignition channels ee ¹ , which are fed with gas through the pipes e ³ e ³ , come into contact with the ignition flames / ² and the resulting flame in e or e ' passes through the bore e ² , Fig. S and 9, which is communicated to the chamber h charged with the mixture. This ignition takes place immediately before the ignition channels ee 'come into communication with the channel d and the explosion of the mixture in the ignition chamber h is communicated to the compressed mixture in the cylinder C. From the moment when the openings of the channels e and e ^{1 of} the slide leave the openings // 'in the slide valve case lid M until the point in time when they communicate with the ignition chamber h and then with the channel d , the slide is in motion L is an accelerated one, caused by the shape of the section η formed from curves in the loop JV, FIG. 8.

The ignition chamber h is emptied of the combustion products formed immediately after the explosion through the lower slot of the chamber, which is connected through the opening h ² and a suction pipe to the cylinder B ¹ , the piston D ^{2 of} which causes the evacuation.

The two slides J and L move only at half the speed of the piston, brought about by the transmission of the bevel gears JJ ¹ , which drive the shaft H , the rotation of which by the bevel gears kk ¹ on a vertical, the lower slide J reciprocating Wave is transmitted, as shown in FIGS. 2 and 3.

The regulation of the movement is effected by a swing ball regulator, the balls Q of which, at accelerated speed, cause the lowering of a sleeve, FIG. 13, which can be displaced on the spindle Q ^1. As a result, the curved arm R is rotated and the sleeve set ^{2 is} displaced on the pin of the lever S, Fig.'8. The disk R ^{s of} this sleeve grinds gradually with increasing speed from the lowest straight track T, Fig. 18, over the middle notched track, Fig. 17, on the upper track T ² , Fig. 16, whereby the smaller arm of the lever .S lifted and the angle lever P, Fig. 8, 14 and 15, which is connected to the gas tap c , is rotated so that the openings c ^{1 are closed} for the entry of the gas.

Conversely, when the machine is running too slowly, the disc R ³ slides from the high track T ² down onto the track T, as the lowering of the balls pushes the sleeve R ² in the opposite direction and, due to the incline of the longer lever arm 5, the angle lever JP and the cock c are turned so that the gas outflow openings c ^{1 of the} same coincide with the corresponding openings in the valve body cover M.

In normal gear, the disc R ^{1 is} in contact with the central track T ¹ .

The lubricator is shown by FIGS. 1 ^ and 20. It consists of the oil container U ₁ from which the oil is pumped with the aid of a small piston / through the eccentric q to the parts to be lubricated. One free end of this piston is beveled. During the retraction of the piston caused by the spring r , the space t fills through the channel ν with OeI, which is now only driven through the angled bore u and the channel v ¹ to the points to be lubricated when the piston moves forward.

20 shows a device in outline, by means of which by means of a connecting pipe U ¹ and a second pump the oil is pressed from a single oil container at two or more points on the machine for lubrication.
