Device on double-cylinder, rotating steam engines for control, respectively Reversal of the same.

Patented in the German Empire on July 6, 1877.

This machine consists of the double cylinder e, the bores of which touch, the cast iron piston f in the form of straight-turned rollers with the steel shafts g and the steel blades h; these are eccentric to the bore of the cylinder and run tightly against each other and through the latter form a secure seal (without end) between the steam inflow and outflow.

Furthermore, the reversing slide valve i with the adjusting mechanism, the slide valve housing k with the shut-off valve υ and the stuffing boxes for the exhaust pipes /, the cylinder lids m with screwed-on eccentrics η, stuffing box and bearing brackets, the steam pipe 0 with screws /, the bearings q with the wedge device u and the pair of spur gears r.

As indicated by the position of the slide on the drawing, the steam enters the lower slide housing k through the steam pipe ο and the open valve ν , goes around the slide i through the open three central inflow channels into the two cylinders and presses against the Wing h and thereby rotates the pistons in the direction of the arrow. Arrived at the upper, outer channels (only used for steam outflow), the steam escapes through them, as well as through the three middle channels, then through the slide i and the steam outlet pipe /. If one wishes to work with a smaller filling, then the slide valves are set so that only the central channel remains open and the two lateral inflow channels are closed. The steam outflow channels are kept so wide in the sliders that this slider position does not prevent the free escape of steam.

If the slide is set in motion for the purpose of reversing, the attachment χ on the slide rests against the pin of the valve cone υ and opens the valve. Since the slide movement is now opposite to one another, the valve on the other side is closed. The steam now works in the same way as before, turning the pistons in the opposite direction. The valves ν also have the primary purpose of relieving that slide which is set for the outflow when the machine is in motion and to prevent water from collecting in the valve body. The eccentrics screwed onto the cylinder cover sit centrically with the cylinder bore and serve to hold the blades h against the cylinder wall when the machine is started. When the machine is in motion, the eccentrics are less effective because the centrifugal force then flings the wings outward.

The pair of spur gears r is used to keep the pistons always moving in the same direction and to combine the power of both.

The machine shown in the drawing is for approx. 10 P ^s . Their efficiency is significant in relation to their low steam consumption.

Because of the small space that the machine takes up, because of the high speed and the With the possibility of reversing the movement, the machine would be particularly suitable for ship or conveyor machines.
