A preferred embodiment includes an electric motor of the drive input and output assembly powered by a battery pack. Advantageously, the yoke-style shifting assembly: improves and simplifies design and operation of shifting; reduces tool size and cost; and increases tool portability, efficiency, reliability and repeatability, all without sacrificing Applicant's many innovations in hand-held, multispeed torque intensifying tools.
An apparatus for use with a hydraulically driven torque tool for tightening or loosening threaded fasteners including an internal energy storage assembly for automatic piston return is disclosed. In one embodiment, the internal energy storage assembly operates by a pneumatic fluid which compresses during an advance stroke of a piston assembly of the tool and expands during a retract stroke of the piston assembly of the tool. In such embodiment, the internal energy storage assembly includes a hydraulic assembly and a pneumatic assembly. Advantageously it: has a higher energy density than a mechanical spring; does not have geometric limitations as the pneumatic fluid may be contained in internal volume available of the tool; and increases bolting speeds as the return stroke no longer requires hydraulic fluid to force back the piston; has reduced tool size by elimination of one hydraulic connection and location of the remaining connection that improves accessibility of the tool into the work space; requires a simplified hydraulic pump and controls; and increases bolting system reliability.
Torque tools of the present invention include: a hydraulic cylinder assembly (40); a drive assembly (600, 60); a flexible linkage connection, or force transfer, assembly formed between the hydraulic cylinder assembly (40) and the drive assembly (600, 60); all of which is formed within or adjacent to a housing assembly (70). They provide large, accurate torque for limited clearance applications. The flexible linkage connection assembly (50) includes a rocker arm assembly (51) and a chain link-pin assembly. The flexible linkage connection assembly (50) maintains the relationship between the line of action of the linear force generated on the rocker arm assembly (51) by the hydraulic piston assembly (44, 50)(ies) and rotary force generated on the ratchet drive socket (9) by the rocker arm assembly (51) via the chain link-pin assembly at close to the optimized position throughout the entire travel of a drive plate assembly (61) of the drive assembly (600, 60). The resulting efficiency increase of converting linear force and displacement into rotary torque and angular displacement allows for generation of large and accurate torque in minimal cross-sections necessary to access hidden, limited clearance and/or inaccessible threaded fasteners.
This application discloses an apparatus 100 for use with an electrically, hydraulically and/or pneumatically driven torque tool for tightening or loosening inaccessible threaded fasteners including a drive extension assembly 110, a reaction assembly 120 and a socket assembly 130.

It more efficiently distributes/reduces the side loads and system strains from the reaction forces on the bolts by bringing the reaction point much closer to the fastener being turned. It allows for a plurality of fastener approach angles and is adaptable to a plurality of fastener obstructions. It's relatively lightweight, easy to maneuver from fastener to fastener and overall user friendly.
A rotation angle indicating retainer assembly for use with and/or integrated with a hydraulically driven device for tightening and loosening a threaded fastener is disclosed and includes: a retainer cap assembly having a hollow cylindrical shape with an upper hollow portion, a lower hollow portion, a hollow disc, a ring having polygonal connection formations and a ball bearing assembly; a plunger assembly having a cylindrical shape with a connection portion, a depression portion, a compression spring and a lower retaining ring; a rotation angle scale assembly having a hollow cylindrical shape with an upper hollow disc with an arrow indicator and a lower portion having polygonal formations; a rotation angle indicator assembly having a substantially hollow cylindrical shape with an upper rotation angle dial, a lower portion having a rotation angle scale, an upper retaining ring, a wave spring and friction ring; and wherein the rotation angle scale assembly is nonrotatably attachable to a driving portion of a housing of the device, and wherein the retainer cap assembly is nonrotatably attachable to a square drive shaft torque output assembly of the device. Advantageously the rotation angle indicating retainer assembly: is not connected with a device power source; is not used in a feedback loop between the device, the device power source and/or the fastener; is able to be zeroed once an operator wishes to observe an angle of rotation of the fastener; is of unitary construction; requires no loose parts or external implements to engage and secure a drive shaft to the drive head of the tool; reduces likelihood of tool failure during operation due to improper engagement of the drive shaft; and increases user safety during tool operation.

According to a first aspect of the invention we provide a low clearance face tooth ratchet assembly for link drive means of hydraulic torque tools. The face tooth ratchet assembly includes: a drive plate having piston engagement means at a first end and a machined face gear with radial serrations at a second end; and a ratchet drive having a machined face gear with corresponding radial serrations at a first end and a threaded fastener engagement means at a second end. Advantageously the low clearance face tooth ratchet assembly minimizes volume and mass of the tool. Only one drive plate is necessary which is tapered from a first end to a second end. Further, side plates of the link drive means are tapered from a first end to a second end. Such geometry minimizes the width of portions of the link drive means making the second end, adjacent the threaded fastener engagement means, substantially thinner than the first end, adjacent the piston engagement means. Higher torque values are transferred in a smaller enclosure via only two parts. Notably no drive and/or reaction pawl is necessary as the teeth of the drive plate and the ratchet drive achieve full facial engagement. The design of the connection coupling is backlash-free, maximizes tool safety, minimizes risk of failures/fatigue from wear, bending, scuffing and cracking, and is suitable for changing forces.

A hand-held torque power wrench for tightening and loosening fasteners, the torque power tool has a motor, a housing, at least one handle configured to hold the torque power wrench in a position and to pull a trigger with one hand of an operator, and a safety device operatable by the other hand of the operator, so that when it is operated by the other hand of the operator the torque power wrench is functioning to tighten or loosen the fastener, but when the only one hand of the operator is used for holding the torque power wrench in position and pulling the trigger, the torque power wrench is not functioning to tighten or loosen the fastener.
An apparatus for calibration of a fluid-operated power torque tool having a housing and a drive has a non-turnable torque measuring unit for measuring a torque generated by the tool, a non-turnable abutment unit, a first connecting element configured for connecting the drive of the tool with the torque measuring unit, for measuring a torque generated by the tool when a fluid pressure is applied to the tool, an adjustable braking unit configured for providing an adjustable braking force, a second connecting element configured for connecting the housing of the tool with the adjustable braking unit to apply the adjustable braking force to the housing so as to increase a turning resistance to turning of the housing of the tool, so that when the tool is operated the housing of the tool starts turning at a force determined by the braking unit while the drive of the tool apply an opposite and equal force to the measuring unit, so that when the braking force is increased a fluid pressure required for the tool increases and the tool can be calibrated, by determining the generated torque that corresponds to the applied fluid pressure, without inertia.
A fluid operated torque tool tightens a nut through a spring washer on a plate on a railroad crossing, and has a housing, two coaxial drives applying equal turning forces in opposite directions around an axis, with one of the two coaxial drives located around the other of the two coaxial drives, a first socket attached to the one coaxial drive and configured to fit on the rectangular plate, and a second socket attached to the other coaxial drive inside the first socket and configured to fit on the nut, with the washer being not engaged by the sockets, so as to tighten the nut and to tighten up the spring washer onto the plate while the first socket and the housing stand still.
A safety torque intensifying tool has a housing, a torque intensifying unit providing at least two modes of operation including a first mode in which the tool operates with a high speed and a low torque and a second mode in which the tool operates with a low speed and a high torque, a grip to be held by a tool operator, an additional element acting as a handle for better gripping in the first mode in which the tool operates with the high speed and low torque and also as a reaction arm to abut against a stationary object to stop the housing from turning in the second mode when the tool operates with the low speed and the high torque, and a switching unit for switching the tool between the first and second modes and configured so that when the operator does not act on the switching unit the tool is in the second mode of operation with the low speed and the high torque, and when the switching unit is switched by the operator while the additional element acts as a handle, the tool is switched to the first mode of operation with the high speed and the low torque, until the operator stops acting on the switching unit and the tool is switched itself back to the second mode of operation.
A reaction arm for a power-driven torque intensifier having a housing with an axis, a torque intensifier unit and a switching device for switching the torque intensifier unit between high speed/low torque and low speed/high torque, is configured for operating the switching device so that when the reaction arm is placed in a first position, the torque intensifier unit is switched to high speed/low torque and the reaction arm is usable as a handle by an operator, and when the reaction arm is placed in a second position the torque intensifier unit is switched to low speed/high torque and the reaction arm can abut against a stationary object since the high torque can not be absorbed by the operator.
An eccentric gear mechanism, comprising an input drive having a centric portion rotated about an axis and an eccentric portion; a movable inner ring gear having outer circumferential gear teeth, so that said centric portion and said eccentric portion of said input drive turn in one direction against said movable inner ring gear, said inner ring gear being configured in such a way that it allows an eccentric movement by said inner ring gear and transfers a given turning force derived by said inner ring gear in an opposite direction to said one direction; an outer ring gear having inner circumferential gear teeth partially engaged with said outer circumferential gear teeth of said inner ring gear, so that when said given turning force is derived by said inner gear ring in said opposite direction said outer ring gear rotates around said axis, and said outer ring gear transfers said given turning force in said one direction outwardly along said axis.
