Fluid-Operated Torque Wrench
View pageUS Patent:
6802235, Oct 12, 2004
Filed:
Jan 4, 2002
Appl. No.:
10/037991

Peter Koppenhoefer - Portland PA
Assignee:
Unex Corporation - Mahwah NJ
International Classification:
B25B 1346
US Classification:
81 5739, 81 5744
Abstract:
A fluid operated torque wrench has a housing having a cylinder portion with a cylinder having an axis and a driving portion; two pistons movable in the cylinder along the axis independently from one another and having piston rods; two ratchet-lever mechanisms located in the driving portion; a drive element to which both the ratchet-lever mechanisms are connected; a fluid supply into the cylinder, the pistons being formed so that when the fluid is supplied at opposite sides of the pistons, either one ratchet-lever mechanism turns and the other ratchets, or vice versa.
Fluid-Operated Power Tool

6925911, Aug 9, 2005
Filed:
Feb 2, 2004
Appl. No.:
10/770209
Inventors:
Peter Koppenhoefer - Portland PA, US
Assignee:
Unex Corporation - Mahwah NJ

B25B017/00
B25B017/00
US Classification:
81 5739, 81 5736, 81 5724
Abstract:
A fluid-operated power tool has a drive including a fluid-operator cylinder-piston unit, a first housing accommodating the drive, a lever-drive mechanism connected with the drive and powered by the latter and also engageable with a fastener for bolting applications, a second housing accommodating the lever-drive mechanism, the housings being interconnected so as to turn a fastener when the lever-drive mechanism is connected to the fastener and powered by the drive, and a connection for releasably connecting the housings with one another so that the housings are connectable with one another and disconnectable from one another, the connection including a female portion provided in one of the housings and a male portion provided in the other of the housings and engageable with the female portion for operatably connecting the first housing and the second housing with one another without subsequently requiring additional pins, screws and other means to provide a connection between the housings.
Holding Socket For A Threaded Fastener
View pageUS Patent:
7188552, Mar 13, 2007
Filed:
Oct 14, 2005
Appl. No.:
11/251265
Inventors:
Peter Koppenhoefer - Portland PA, US
Assignee:
JETYD Corp. - Mahwah NJ
International Classification:
B25B 13/06
B25B 13/48
B25B 13/48
US Classification:
81125, 81 55
Abstract:
A holding socket for a fastener having a nut arrangeable on a threaded element, and a washer located between the nut and an object, the holding socket has a body having two opposite ends with a first end connectable to a part of a power tool and a second end which is axially spaced from the first end and connectable with the washer so as to hold the washer against rotation, and a locking element located in an area of the second end of the body and displaceable transversely to the body between a position in which it is located axially between the second end of the body and the nut and therefore prevents a removal of the socket from a fastener and another position in which it is no longer located axially between the second end of the body and the nut, and therefore allows withdrawal of the socket from the fastener.
Torque Tool For Tightening Or Loosening Connections, And Method Of Tightening Or Loosening The Same
View pageUS Patent:
7497147, Mar 3, 2009
Filed:
Aug 28, 2007
Appl. No.:
11/846005
Inventors:
Peter Koppenhoefer - Portland PA, US
Assignee:
Unex Corporation - Mahwah NJ
International Classification:
B25B 13/46
US Classification:
81 5739, 81 5744
Abstract:
A torque tool for tightening or loosening connections has a driving element engageable with a turnable part of the connection for turning the turnable part of the connection for tightening or loosening the connection and turnable about an axis, and a power drive configured for acting on the driving element such that the drive acts on the driving element to turn the driving element and thereby to turn the turnable part of the connection over a partial stroke and a space is formed between the drive and the driving element, and the drive is then displaced over the space toward the driving element to act again on the driving element to turn the driving element and thereby to further turn the turnable part of the connection over a further partial stroke.

B25B 17/02
B25B 13/48
B25B 17/02
US Classification:
81 55, 81 5742
Abstract:
A torque intensifying tool for tightening and loosening threaded connectors has at least one torque intensifier unit with a torque intensifier housing portion, an input and a first output and a second output, a drive connected with the input unit for transmitting a torque from the drive through the intensifying unit to a threaded connector, so that in one mode of operation the housing portion together with the first and the second outputs turn in the same direction, and in another mode of operation the housing portion together with one of the first and second outputs receives a turning force in one direction while the other one of the first and second outputs receives an equal turning force in the opposite direction, and so that one of the first and second output means turns in the one mode and in the another mode while the other of the first and second output means turns in the one mode and reacts in the another mode.
Fluid Operated Tool For Tightening And Loosening Threaded Connectors
View pageUS Patent:
20020121161, Sep 5, 2002
Filed:
Mar 5, 2001
Appl. No.:
09/799455
Inventors:
Peter Koppenhoefer - Portland PA, US
International Classification:
B25B013/46
US Classification:
081/057390
Abstract:
A fluid-operated tool has a ratchet link assembly provided with ratcheting mechanism for engaging and turning a threaded connector, a fluid-operated drive assembly releasably connectable with the ratchet link assembly, and a unit for releasably connecting the fluid operated drive assembly with the ratchet link assembly, the connecting unit including an opening provided in one of the assembly, a projection provided in the other of the assemblies and insertable into the opening, and a blocking member which block the projection in the opening in an assembled condition of the assemblies, the blocking member being operable by a user to unblock the projection and to allow withdrawal of the projection from the opening so as to release the assemblies from one another. The opening and the projection are formed so that in operation during an advance stroke of the fluid operated drive the projection is urged further into the opening.
