Mechanical toys; stationary engines. - A toy fluid-pressure engine of the oscillating cylinder type is controlled by varying the position of the axis of oscillation of the cylinder. The cylinder i' of a stationary steam engine is pivoted on a pin a that is adjustable within a slot in a plate h by means of a lever d. The facing i of the cylinder is pressed against the surface of the plate by a compression spring k on the pin a. The plate is provided with a steam port c, on either side of which is disposed an exhaust port f. In extreme positions of the lever d, the cylinder port c1 co-operates with the steam port c and one or other of the exhaust ports f to cause the engine to run forwardly or in reverse. In intermediate positions of the lever, the engine is stopped. The invention may be applied to toy locomotives, the lever d being arranged to cooperate with stops on the track for control purposes. Spring means may be provided on the track to assist reversal of a locomotive on dead centre.
