  • Patent number: 5060912
    Abstract: A holder for a vehicle spare tire which diminishes the possibility of tire theft from the vehicle. The holder includes a hoist attached to the vehicle frame. This hoist is driven by a key wrench which engages a key aperture associated with the hoist drive means. A flexible guide directs the key wrench from the exterior portion of the vehicle into its key aperture. The guide comprises a flexible spring which is associated in a slidable relationship with the hoist. The flexion and/or slidable connection of the guide precludes operation of the hoist by manipulation of the guide. The key wrench is user-driven by a drive tube/lug wrench combination. The flexion and/or slippage connection cooperates with the key wrench assembly so as to diminish the possibility of operation of the hoist and lowering of the spare tire to the ground by non-authorized users.

  • Patent number: 4628777
    Abstract: A tool for use in the lubrication of a slip joint formed by a spline connection between a shaft and a sliding yoke in a two piece vehicle driveline. The tool includes a pair of spring brackets having legs which grip the yoke. An L-shaped spring arm has one end connected to a rigid plate secured to the brackets. The other end of the spring arm carries a plug having a conical tip which plugs a vent hole in the yoke when lubricant is applied to the slip joint. The spring arm holds the plug in the vent hole to assure a complete fill of the slip joint with lubricant and yields if necessary to relieve excessive pressure which could damage the slip joint seal.

  • Patent number: 4498614
    Abstract: A storage device which fits within the rim of a spare tire and can be locked to secure its contents against unauthorized access and to lock the spare tire itself. A pan shaped container has a closed bottom which is secured to the hub of the wheel by the same fasteners that mount the spare wheel to its mounting bracket on the exterior of the vehicle. The interior of the container provides a storage compartment for tools and other articles. A removable cover panel encloses the storage compartment and can be locked in place on the container by a key operated cylinder lock. The storage device can be used with a flexible tire cover which covers the spare tire and is secured to the cover panel of the container by the cylinder lock in cooperation with a large washer.

  • Patent number: 4441345
    Abstract: A lock device for locking the hood of a vehicle equipped with a pivotal latch. A mounting bracket is bolted to the vehicle at a location adjacent to the hood latch behind the vehicle grill. A key operated cylinder lock carries a cam which controls a spring loaded locking arm. A flange on the locking arm engages the latch release lever to prevent it from releasing the hood when the cylinder lock plug is turned to the locked position. The cam releases the locking arm when the cylinder lock is unlocked, and a spring pulls the locking arm away from the release lever to permit unlatching of the hood. In a modified form of the lock device, the cam acts directly against the latch release lever to provide the sole means for operating the latch.
