Abstract: A lockout device is provided for inhibiting the selection of certain gear combinations in range shift type transmission. The lockout device comprises an air cylinder mounted to the transmission housing. The air cylinder includes a rod selectively translatable between a retracted position and an extended position. The rod is normally urged to its retracted position, and extends through an aperture in the housing in its extended position to engage a notch in a selected shift rail. The air cylinder and the high range air line are operably interconnected, whereby a shift to high range simultaneously activates the air cylinder, extending the rod into the recess in the shift rail to thereby selectively limit axial translation of the shift rail. The lockout device is easily removable.

Abstract: A peg is securable to each shoe and is releasably attachable to a bracket secured to each bicycle pedal. The bracket is securable to a conventional bicycle pedal for example by using screws and screw holes normally provided on conventional pedals for mounting reflectors, or the like, thereon.

Abstract: An improved punch retainer is disclosed in which a backing plate extends over a relatively large surface area to dissipate force from a punch. A punch retainer body and the tacking plate are permanently connected to each other and include passages which are finally ground after the two have been permanently connected. With this arrangement, it is ensured that passages within the backing plate and retainer body are all properly aligned during formation of the punch retainer. Since the backing plate dissipates force over a relatively large surface area, the punch retainer may be used in heavier applications than prior art punch retainers. A spring passage may be closed off by a seal received in the backing plate, allowing the use of standard springs. In a method according to the present invention, a dowel passage in the backing plate is finally ground such that it is centered on the center line of the punch within the retainer.

Abstract: The cleat removal/install tool has a handle with a first end and a second end. A ratchet is positioned within said handle member proximate said first end. A cleat receiving tool is positioned within said ratchet member or is directly built as part of the ratchet member The cleat tool has a concave surface which functions to mate with the upper surface of the cleat.

Abstract: An ammunition bunker rests against a military tank turret. The bunker's outward-facing walls are scored. The bunker wall facing the crew compartment is unscored. The ammunition stowed in the interior of the bunker points away from the crew compartment. The bunker is a separate and totally enclosed housing.
