Abstract: Apparatus for the selective engagement and disengagement of a ring gear of a gear set in which an actuator can be displaced between a first position engaging the ring gear and a second position disengaged from the ring gear selectively by a manually operable mechanical arrangement or a fluid pressure arrangement without altering or adding to the housing or control device of the gear set. The mechanical arrangement and the fluid pressure arrangements are integrated so that the operation of the actuator can be selectively achieved either by the mechanical or fluid arrangement.

Abstract: A rationing container to carry liquid while running or walking is shown as including a narrow bottle with an offset neck and a handle. The bottle is carried tethered in a holder on a person's belt. Drinks in two approximate amounts are dispensed from the bottle through a moveable spring-biased mounthpiece which has a rod extending to a stopper near the bottom of the bottle. The stopper covers an opening between the bottom of a tube extending through the bottle as an extension of the bottle neck and a separate liquid holding chamber which has a small opening to the larger interior of the bottle. The bottom of the mouthpiece includes a plug member which plugs an opening in a fixed gate at the top of the tube. The plug is pulled out of the opening by action of the mouthpiece and is rested on the top of the fixed gate for one rationed drink. For a longer drink the plug member is rested in a recess on the top of the fixed gate allowing liquid from the holding chamber into the tube.
