PATENT OFFICE.

In the gas engine shown in FIGS. 1 and 2 with a special cylinder D, in which the compression of the explosive mixture to be introduced into the working cylinder A takes place, the working piston B is provided with a longitudinal channel g which is closed by a valve h in order to evacuate the combustion gases is held and. creates a connection between the working space and the outlet channel w to the vessel Α ^Λ. When the piston B is lifted in, the. Attached to the connecting rod b stop α on the bracket j connected to 'the valve rod / ι ¹ and thus, against the action of the spring k, brings about an opening of the valve h so that the combustion gases pass through the channel g to the outlet w can. This opening of the valve h can also take place by another suitable mechanism.

The gas engine shown is provided with devices for starting and stopping. In some cases it is not practical to use an auxiliary power source to operate the machine to set in motion. This can then be done by using the machine in this way continues that a compressed charge in the working cylinder or some other container remains, which, when lit, puts the machine into operation. Or one, such a charge can stored in an auxiliary cylinder and inserted into the working cylinder by means of easily movable control organs without turning the engine flywheel shaft needs. ,

The following facilities are used for this purpose:

The eccentric rod E ² is not fixed to the piston rod E of the compression piston, but is connected by means of a coulisse E ⁱ of a peculiar, triangular shape. The leg χ of this coulisse is arcuately curved according to a circle described around the center of the shaft C. The rear leg λ; ¹ is straight and inclined at an acute angle towards the arched leg. If the end pin ν of the eccentric rod E ^{2 is} in its upper position, it will cause the piston to move back and forth as usual; However, the parts occupy the solid lines in Fig. 3 line position, so in the Compressionscylinder a charge on the oblique leg. * ¹ is present, which is conveyed into the Arbeitscylinder when the Excenterstange is lifted and v, with its pins, contact type, the coulisse E ¹ and thus the piston rod E and the piston of the compression cylinder pushes to the left. The charge thus entering the working cylinder explodes and starts the engine. The eccentric rod E ² can here by means of a rope Q from a distant point, e.g. B. from an elevator car to be handled.

In order to stop the motor in a suitable position of its driving parts, you can various devices can be used.

A brake that acts on the flywheel and locks it in place at the right moment.

brakes, is suitable e.g. B. very good for this purpose. In Fig. Ι the shoe brake Z is firmly tightened against the circumference of the flywheel Y by the eccentric rod W provided with a lug y , so that the flywheel stops at the desired point.

The eccentric rod W is attached to the eccentric rod E ^{2 by} means of the pull rod u with a slotted hole, while a second pull rod with its slotted hole holds the pin p ^{1 of} the rod W , but on the other hand is connected by a lever F to the rod H going to the regulator.

If the eccentric rod E ^{1 is} lowered to stop the machine, the pin ν of the rod E ^{2 will play} back and forth in the lower, wider part of the coulisse E ^i, hit the leg x ^{x, and} pull the piston of the compression cylinder all the way to the right and leave it in this position while the machine continues to run for the time being as a result of the living force still contained in the flywheel, until the speed decreases, the regulator decreases, the rod p lowers and the rod W with its hook y grips the brake ζ and the Braking of the flywheel y occurs in the course of the following revolution of the same. As a result of the arrangement of the individual parts described, braking will only take place when the machine has almost come to a standstill, so that the flywheel stops at such a point that the pin ν assumes the position in Fig. 3 without stopping a substance occurs.

The charge can be carried out at any time through a special valve with a constant flame ignited, whichever valve is handled from a distant point can be, or you can use an electric spark for the same purpose, which is generated by closing a circuit will.

For alternators you can let the braking mechanism work without the regulator is active here.

Claims (3)

Patent Claims: 1. The process of stopping the operating shaft and piston in gas engines at such a point that an explosive charge remains in the cylinder or can be introduced into the cylinder when it is started, as well as the arrangement of a brake, which starts automatically from the flywheel shaft, for carrying out this process is put into action and the same stops at a certain point, in particular the combination of the shoe brake Z with the pull rod W with hook y, which is held respectively by the pull rod, a rod p and the rod 11 connected to the eccentric rod E ^2. is moved. ' 2. In combination with the compression cylinder of a gas engine, the arrangement of the coulisse Ε ⁴ · and the movable eccentric rod, which coulisse can be attached to the piston or eccentric rod. 3. The channel g fitted in the piston B, FIG. 1, with valve / z, which is opened at the appropriate moment in order to allow the combustion gases to escape to the channel w. 1 sheet of drawings.
