Patent number: 12128529Abstract: The device is a multi-purpose drive socket capable of engaging both a penta-bolt and a hex-bolt. The device is specially adapted for use in the utility industry where multiple tools are typically needed for securing electrical equipment. The device contains a retractable plunger that slides in and out of the head opening. To remove a penta-bolt, the user simply presses the plunger head up against the head of the penta-bolt, causing the plunger to retract back into the socket body. Once fully inserted, the user can loosen or tighten the penta-bolt. To remove a hex-bolt, the user inserts the hex-head into a recessed opening in the plunger head and tightens down the hex-bolt until the hex-head breaks off at the shank. In the event the hex-head remains lodged in the plunger, the device also contains an ejector pin capable of dislodging and removing the hex-head.Type: GrantFiled: April 11, 2024Date of Patent: October 29, 2024Inventor: David Butler Lark
