081570300 | Parallel axis drive | 10 |
20080196554 | Rocket socket - This invention compliments an improved way to use threaded rod in the construction industry. It is a unit that is drill driven and it is designed to be compatible with go-through socket inserts of various sizes and die-threading inserts of various sizes. The unit comprises a focal point for go-through socket insertion that is offset away from its drive source, which allows where said length of all-thread to bypass the base of the go-through socket and the drill. | 08-21-2008 |
20080210060 | RIVET SETTING DEVICE FOR SETTING SELF-TAPPING RIVETS - A rivet setting device for setting a self-tapping rivet in a work piece includes a rotatable head for rotating a self-tapping rivet to form a hole in the work piece and a shank retracting assembly for compressing and spreading the hollow body of the self-tapping rivet, allowing the head of the self-tapping rivet to detach from the shank upon application of a predetermined tensile force. The rotatable head comprises a clutch having a body enclosing a plurality of bearings circumferentially located around the shank, for gripping the shank. The clutch is formed with a plurality of tapered channels for urging the bearings into engagement with the shank upon rotation of the clutch. | 09-04-2008 |
20110017023 | OFFSET PASS THROUGH DEVICE - A device having a pass through formed therein that is offset from point where energy is received in order to perform a function (e.g., drive, tighten, thread, cut) on a material (e.g., pipe, rod) passing therethrough. The device may include a coupler to connect to an energy source (e.g., drill, impact gun, hand crank), an insert within the pass through to perform the functions, and gears (number and type may vary) to transfer the energy from the coupler to the pass through. The insert may perform the functions or may receive tools to perform the functions. The device may include two substantially similar pass throughs capable of receiving the insert or the coupler so as to provide a configurable device (e.g., torque vs. speed, push vs. pull) The coupler may be rotatable around the perimeter of the device to allow one to work in hard to reach places. | 01-27-2011 |
20130233131 | POWER WRENCH ATTACHMENT - An attachment including open end box wrench adapted to be attached to and to be driven by a power tool though an input gear of the attachment, the input gear driving an output gear and the wrench | 09-12-2013 |
20150122086 | WRENCH - The present invention provides a wrench, which comprises a working part and a handle, the working part includes a main axle perpendicular to the handle and mutually cooperated bidirectional pawl and ratchet wheel, in which the ratchet wheel is arranged so as to be caused by the handle, the bidirectional pawl is arranged to rotate the main axle and has a first pawl and a second pawl which are opposite to the clutch direction between the ratchet wheel, the working part also includes a direction switching mechanism for setting clutch direction of the bidirectional pawl and the ratchet wheel; the direction switching mechanism is arranged such that a first pawl and a second pawl are engaged with the ratchet wheel selectively, such that when handle is rotated in the direction set by the direction switching mechanism, the ratchet wheel is engaged with the bidirectional pawl, then rotates the main axle; when the handle is rotated in the direction opposite to the direction set by the direction switching mechanism, the ratchet wheel and the bidirectional pawl slide over each other, and the main axle remains stationary; the working part also includes a planetary gear speed increasing mechanism acting on the main axle, the planetary gear speed increasing mechanism includes a sun gear, a planetary gear and a ring gear, in which the sun gear is arranged to rotate the main axle together, the rotation ring is arranged so as to cause the planetary gear to rotate, the gear ring is fixedly connected with the handle, so that when the handle is gripped and the rotation ring is rotated, the planetary gear speed increasing mechanism increases the speed of the rotation inputted by the rotation ring and then outputs via the main axle. | 05-07-2015 |
20150314427 | POWER TOOL ATTACHMENT PART - An attachment part for tightening joints includes: an elongate housing including an upper housing part and a lower housing part, an input gear wheel for connection to an output shaft of a power wrench, arranged at a first end of the housing, an output gear wheel for connection to a joint to be tightened, arranged at a second end of the housing, and at least one intermediate gear wheel arranged inside the housing to transmit rotation of the input gear wheel to the output gear wheel, wherein each gear wheel has outer slanted teeth that connect the gear wheels and transmit said rotation there between. | 11-05-2015 |
20160023332 | OFFSET WRENCH AND POWER TRANSMISSION MEANS - The present invention is tool for transmitting torque from one end of the tool to the other comprising a housing having an input sprocket and an output sprocket connected by a race containing ball bearings whereby torque applied to one sprocket is transmitted to the other sprocket via movement of the ball bearings. The tool can be configured as a wrench for removal of nuts, bolts and screws or as a drive transmission means for applying torque from a source of rotary motion to a device requiring rotary motion to drive it. | 01-28-2016 |
20160067849 | APPARATUS FOR TIGHTENING THREADED FASTENERS - An offset drive link assembly for transmission and multiplication of torque from a power tool for tightening or loosening a threaded fastener includes: a drive force input assembly having a drive force input engagement to receive a first turning force from the device acting in a first direction; a drive force output assembly operatively engageable with the drive force input engagement, having a drive force output engagement to transfer the first turning force to the fastener; and a reaction force assembly having a reaction force input engagement to receive a second turning force from the device in a second direction and a reaction force output engagement to transfer the second turning force to a stationary object. | 03-10-2016 |
20160167207 | POWER WRENCH ATTACHMENT | 06-16-2016 |
20160375564 | DUAL-SETTING DIRECTIONAL TOOL - A dual-setting rotating system selectively provides unidirectional rotation to a drive shaft. Along with the drive shaft, the system includes a primary ratchet gear fixedly disposed on the drive shaft and configured to motivate the drive shaft in principal rotation. A secondary ratchet gear is coaxial with the primary ratchet gear and rotatably attached about at least a portion of the drive shaft. A pinion gear is axially-aligned with the drive shaft and operably engaged with the secondary ratchet gear and a shaft gear to motivate the drive shaft during retrograde rotation. The shaft gear is rigidly attached to and coaxial with the drive shaft. A clutch plate spans the primary and secondary ratchet gear while a main body encloses at least a portion of the clutch plate. | 12-29-2016 |
