Patent number: 10814461Abstract: A power driven direct drive ratchet/wrench tool allows a user to tighten and loosen fasteners in tight spaces efficiently and effectively. The tool includes a tool housing, a engagement body, a spur gear, a drive shaft, and a plurality of drive pins. The tool housing acts as the structural element and includes a ratchet head, a tubular handle, and a gear-receiving cavity. The ratchet head is terminally connected to the tubular handle. The gear-receiving cavity laterally traverses into the ratchet head and houses the spur gear and the engagement body. The drive shaft is rotatably mounted within the tubular handle. The plurality of drive pins is connected to a proximal base of the drive shaft, about a rotation axis of the drive shaft. In order to transmit torque, an at least one arbitrary pin from the plurality of drive pins is mechanically engaged to the spur gear.Type: GrantFiled: August 21, 2018Date of Patent: October 27, 2020Inventor: Robert S.

Publication number: 20180147698Abstract: A screw bit body which allows for efficient torque force application onto a socket fastener from a variety of angles. The screw bit body includes a plurality of laterally-bracing sidewalls, a first base, and a second base. The laterally-bracing sidewalls are radially distributed about a rotation axis of the screw bit body with each further including a first lateral edge, a second lateral edge, a concave surface, a convex surface, and an engagement cavity. The convex surface is adjacent to the first base and the concave surface is adjacent to the second base to create a ball-like shape. The engagement cavity creates a gripping point to prevent slippage in between the screw bit body and the socket fastener. The engagement cavity traverses normal and into the concave surface and the convex surface. Additionally, the engagement cavity traverses into the screw bit body from the first base to the second base.Type: ApplicationFiled: January 29, 2018Publication date: May 31, 2018Inventors: Robert S.
