Latest Patents
One of his latest patents is for single and double latch operating devices with improved rack-pinion. This invention features a novel rack-pinion that serves as an outside operator for either a single latchbolt or a double latchbolt. The design allows for the pinion to rotate a latch operator, moving the bolt between extended and retracted positions. The rack can shift between pinion engaging and non-engaging positions, controlled by an inside operator control button. In the single latchbolt form, a lock can be added to the outside operator for additional functionality. In the more complex double latchbolt form, a second bolt, preferably a deadbolt, can be operated by either an outside lock or an inside turnpiece. Additionally, a panic assembly can be connected for simultaneous operation of both latchbolts.
Another notable patent is the doorlatch knob assembly having front end loading. This design allows for exterior free knob rotation, which can engage or disengage the latch bolt through cam means. The doorlatch can also feature an exterior key-operated lock that shifts the cam means for driving the latch. The assembly includes a cylinder with a plug that can be rotated out of phase for easy installation. A flange on the plug ensures proper rotation during assembly and removal.
