Innovations in gas engines for locomotives.

Patented in the German Empire on August 19, 1881.

The present innovations in gas engines consist in the application of means to to start such machines easily and, in the case of them, used as locomotives to paralyze their action in order to be able to stop the chariot without the Bring the machine to a standstill; finally in the construction of the one on the locomotive Gas tank.

In order to easily start a gas engine, a strong container is used in which Air or gas is forced under pressure, and a connection between the same and the cylinder of the machine, which is closed by a valve that is operated by suitable control mechanism during several successive strokes of the piston can be opened until the flywheel has received sufficient living force to Make the machine work in the usual way. If this facility is at the so-called Otto's motor or similar machines are used, they can be corriprimed Gases enter during those piston strokes of the cylinder that are not sucking in the filling or the expulsion of the combustion products.

In machines in which the filling is compressed by the movement of the piston, the outlet valve is connected to the mechanism for admitting the compressed gases from the container in such a way that the function of the piston for compressing the filling is canceled by opening the outlet valve until the machine is running.

In order to fill the container with compressed gases, the Machine a part of the combustion products flow into the container, until there is a sufficient one Pressure has been obtained for the above purpose, or the container may mediate one special pump driven by the machine.

Fig. Ι of the drawing shows a side view of the cylinder of an Otto gas engine, with the described container and valve indicated in section.

Fig. 2 is a cross-section through the valve and Fig. 3 is a plan view.

A is the working cylinder and B is a shut-off valve in the channel leading from the cylinder to the container C , which is closed by a helical spring.

The rod of the valve B is moved by one arm of a lever D , the other arm of which carries a roller which rests on a cam plate E which is seated on the control shaft F of the machine.

The disk E rotates with shaft F, but can be moved on the same, for which purpose the lever C serves. In the position indicated, the disc acts on the lever D; this position takes place when the compressed gases contained in the container C are to enter the cylinder A in order to start the engine.

In the normal course of the machine, the disc E is pushed into contact with D , so that the valve remains closed. The effect is as follows:

Claims (3)

When the machine is working, some of the combustion products flow from the cylinder to container C, opening the valve until the pressure in the container becomes almost equal to the maximum pressure in the cylinder, whereupon valve B closes and prevents the gases from flowing over. If, when the machine is at a standstill, it is desired to start the same, the cam E is displaced on the shaft F by means of the lever G until it comes into the position indicated by FIG. 3; the lever D is now moved back and forth once every two revolutions of the machine and opens the valve B for a short time, so that the compressed gases flow from the container C to the cylinder A and thus set the machine in motion. A second curved disk H is connected to the disk E, which takes the place of the usual disk for opening the outlet valve of the cylinder, so that while disk E causes the compressed gases from the container C to be let into the cylinder A, the disk H does that Holds exhaust valve open on each compression stroke of the piston. When E is subsequently brought into contact with D, another part K of the disk H comes into contact with the roller / in order to open the exhaust valve, as usual, only for the purpose of exhausting the combustion gases. The container C could be filled by a compression pump driven by the machine or otherwise, and when this system is employed it is advantageous to arrange the moving parts of the pump so that the moving parts of the machine are thereby balanced, by z. B. connects the pump with a crank opposite the machine crank or an eccentric. When a pump is not in use, the moving parts of the machine can be balanced by means of a sliding weight as indicated in Figures 4, 5, 6 and 7 of the drawings. FIG. 4 shows a side view, FIG. 5 shows a longitudinal section, FIG. 6 shows a cross section and FIG. 7 shows a basic outline. A is the machine cylinder and B the reciprocating weight, in that it is moved by a crank of shaft C arranged opposite the crank of the machine. The shaft C carries pulleys D, which by means of belts drive the pulleys E on the wheel axles. At both ends of the carriage frame shafts F are attached, the cranks of which are connected by arms G to the bearing bushes of the axles. The shafts F carry arms H which are connected to one another by an adjustable rod J, and this rod is extended to the level of the operator, where it can be moved back and forth by means of a rack and gear or some other mechanism. The cranks of F are mounted in opposite directions, and thus when the rod J is moved in one direction or the other, the bearing bushes are either brought closer to one another or removed from one another. In the first case, the drive belts are slack and the wheels are pressed against fixed chocks K at the same time, as a result of which the movement of the carriage is delayed or stopped. In order to put the car back into operation, the wheels are removed from the brake shoes and the drive belts are tightened at the same time , airtight box, open at the top, and B is a slightly smaller lid that can move freely up and down in the box. The edges of lid B are connected to the upper edges of box A by means of a flexible, airtight material C, the is wide enough to allow B to move to the bottom of A. Round bars D are arranged in the bend of material C, and balls E are placed in the rounded corners moves up and down, depending on whether the gas flows into or out of the container, the weight of the rods and balls will keep the material C taut by turning in the bend of the same during this movement. 1. Fill the attached between the container C and the machine A valve B in conjunction with the slidable on shaft F eccentric E and lever £>, Figs. 1 to 3, behufs for the purpose, the cylinder A startup with comprimirten gases from the container C from to . 2. The establishment of laterally displaceable wheel axles in combination with shafts F _1, arms H and rods G, in such a way that when the wheel axles approach, the drive belts become slack and the wheels are pressed against the drag shoes K, FIGS. 4 to 7. 3. The connection of the gas container A with its cover B by means of flexible material C, in the fold of which round rods D and balls E are inserted, for the purpose of keeping the flexible material taut, FIGS. 8 and 9.
