Abstract: An actuator shaft is journaled for rotation within a housing of the apparatus and is coupled to a rotary shaft projecting through the top of a valve or valve actuator. The actuator shaft is coupled to a drum having graphics information on an outer surface thereof, such as the words "open" and "closed". As the actuator shaft rotates the graphics information is also rotated past a window in a window member such that the words observed indicate the position of the valve. The window member couples to an alignment ring which is keyed to receive the window member. By rotating the alignment ring, the window member can be selectively oriented such that the graphics are viewable from a preferred perspective. Each of the components is keyed to be oriented with one another and constrained as a cartridge assembly which can be quickly removed as a single unit to access internal switches and circuitry, whereby the cartridge can be quickly reattached such that the components cannot be inadvertently incorrectly reassembled.

Abstract: A plow for a miniature toy vehicle having a front wheel axle wherein a plow blade extending transversely across the front of the vehicle is fixed to a bracket which extends rearwardly under the vehicle. The bracket has a pair of side plates each of which has a slot receiving the front wheel axle and the slots have vertically spaced notches for adjustment of the plates and the plow blade between upper and lower positions with spring means connecting the axle to the bracket to yieldably retain the bracket in either selected adjusted position.
