Patent number: 10220495Abstract: Coupling mechanisms for engaging and releasing a tool attachment such as a socket from a drive element include an engaging element and an actuating element. The actuating element can include a collar or other manually-accessible part, and various features allow for a relatively small outside diameter for the collar or other part. These features include configuring the actuating element to contact the engaging element within the drive element, placing the biasing elements within the drive element, and forming guides for parts of the actuating element within the drive element. Also, the engaging element can move along a direction that is oriented at an oblique angle to the longitudinal axis of the drive element, in whole or in part. The engaging element can have a first part that moves obliquely in the drive element and a second part that moves radially in the drive element to engage the tool attachment.Type: GrantFiled: April 28, 2014Date of Patent: March 5, 2019Assignee: JODA ENTERPRISES, INC.Inventors: John B.

Patent number: 7472629Abstract: A ratchet wrench has a drive-stud element with a drive stud at a first end and a drive recess at a second end. The drive-stud element is coupled with a one-way drive transmitting wheel to rotate in unison therewith about an axis. The wrench can have a centering element that resists movement of the one-way drive transmitting wheel in at least one direction away from the axis. The drive-stud element and the one-way drive transmitting wheel can be separately formed. A method is also disclosed for operating a ratchet wrench with a drive-stud element with a drive stud at a first end and a drive recess at a second end.Type: GrantFiled: February 17, 2004Date of Patent: January 6, 2009Assignee: JODA Enterprises, Inc.Inventor: John B.

Patent number: 7398713Abstract: A tool of the type having a drive stud for receiving and releasing a tool attachment includes an opening in the drive stud and a locking pin movably mounted in the opening. The opening defines first and second ends, and the first end of the opening is located at a portion of the drive stud constructed for insertion into the tool attachment. An actuating member is movably positioned on the drive stud, and the actuating member defines a sliding surface that engages the pin. A first spring biases the sliding surface toward the pin, and a second, weaker spring biases the pin toward the sliding surface. The first spring reacts against a ring that is disposed between the spring and a shoulder formed on the tool. The shoulder extends away from the longitudinal axis of the drive stud by a lesser distance than the spring or the ring.Type: GrantFiled: October 10, 2002Date of Patent: July 15, 2008Assignee: JODA Enterprises, Inc.Inventor: John B.

Patent number: 7328495Abstract: A torque transmitting tool is machined by registering the torque transmitting tool using a shoulder between the shank and the out-of-round drive portion of the tool as a reference. First and second seating surfaces are milled on first and second opposed surfaces of the tool, and then first and second bores are drilled into the drive stud, starting from the first and second seating surfaces, respectively. The first and second bores intersect within the drive stud to form a stepped diagonal bore in the tool. Alternately, all machining operations are performed from one side of the tool.Type: GrantFiled: May 11, 2006Date of Patent: February 12, 2008Assignee: JODA Enterprises, Inc.Inventor: George F. Charvat

Patent number: 6205890Abstract: A ratchet wrench including a handle, a drive stud, and a ratchet mechanism further includes a tool release mechanism. The tool release mechanism includes a tool release actuator which forms a recess. A reversing lever is coupled to the ratchet mechanism and is movable to forward, non-ratcheting and reverse positions to select a forward ratchet direction, a non-ratcheting action, and a reverse ratchet direction, respectively, for the ratchet mechanism. The direction control element carries a protruding element that is shaped to fit into a recess in the tool release actuator when the direction control element is in the forward position, to remain outside the recess when the direction control element is in the non-ratcheting position, and to fit into the recess when the direction control element is in the reverse position. The protruding element impedes inadvertent operation of the tool release mechanism when the direction control mechanism is in either the forward or the reverse positions.Type: GrantFiled: January 13, 2000Date of Patent: March 27, 2001Assignee: Joda Enterprises, IncInventors: Peter M.

Patent number: 6109140Abstract: A ratchet wrench including a handle, a drive stud and a ratchet mechanism further includes a tool release mechanism. The tool release mechanism includes a control rod that slides along the centerline of the drive stud and a ramp that is slidable in a plane transverse to the drive stud axis. The illustrated actuator is confined to the region of the ratchet wheel, and does not move between the pawl of the ratchet mechanism and the head of the wrench. Centering elements extend from the head of the wrench into an annular recess on a face of the ratchet wheel opposed to the drive stud. The actuator moves in a gap formed between opposed portions of the centering element.Type: GrantFiled: January 13, 1999Date of Patent: August 29, 2000Assignee: Joda Enterprises, Inc.Inventors: Peter M. Roberts, John B. Davidson
