Method And Apparatus For Registering A Torque-Transmitting Tool In A Fixture And For Forming A Diagonal Bore In The Tool
US Patent:
7328495, Feb 12, 2008
Filed:
May 11, 2006
Appl. No.:
11/433136
Inventors:
George F. Charvat - Lombard IL, US
Assignee:
JODA Enterprises, Inc. - Chicago IL
International Classification:
B23B 35/00
US Classification:
29558, 29563, 408 1 R, 408115 R, 76114, 76119
Abstract:
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.
Coupling Mechanisms For Detachably Engaging Tool Attachments
US Patent:
8024997, Sep 27, 2011
Filed:
Oct 30, 2008
Appl. No.:
12/290638
Inventors:
John B. Davidson - Chicago IL, US
C. Robert Moon - Joliet IL, US
George F. Charvat - East Troy WI, US
C. Robert Moon - Joliet IL, US
George F. Charvat - East Troy WI, US
Assignee:
Joda Enterprises, Inc. - Chicago IL
International Classification:
B25B 23/16
US Classification:
8117785
Abstract:
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.
Ratcheting Tools
US Patent:
2006006, Mar 30, 2006
Filed:
Sep 28, 2004
Appl. No.:
10/953470
Inventors:
John Davidson - Chicago IL, US
George Charvat - Lombard IL, US
George Charvat - Lombard IL, US
International Classification:
B25B 13/46
US Classification:
081063000
Abstract:
Ratcheting tools are described that include: (a) a tool body; (b) a driven element; (c) a ratchet mechanism coupling the driven element to the tool body, wherein the ratchet mechanism is configured for adjustment between a plurality of a forward configuration, a reverse configuration, and a neutral configuration; (d) an adjustable first biasing element coupled to the ratchet mechanism and configured to bias the ratchet mechanism to at least one of the forward, reverse, and neutral configurations; and (e) an adjustable second biasing element coupled to the ratchet mechanism and configured to bias the ratchet mechanism to at least one of the forward, reverse, and neutral configurations.
