Patent number: 12076839Abstract: A power ratchet includes a ratchet body and a handle portion connected to the ratchet body. A ratchet assembly is disposed within a cavity of the ratchet body. The ratchet assembly includes a drive member, a pawl, and a ring gear. The ring gear is rotatable within the cavity and includes inner teeth that interface with the pawl. The ring gear has a flange with an interfacing surface and a cam follower. A drive assembly of the power ratchet has a motor and a drive shaft. The drive shaft includes a cam. The cam interfaces with the cam follower when the motor unit rotates the drive shaft to rotate the drive member via the pawl and the inner teeth. The interfacing surface of the flange interfaces with a stop surface formed in the cavity to transfer a torque applied to the handle portion to the drive member.Type: GrantFiled: December 24, 2019Date of Patent: September 3, 2024Assignee: JS Products, Inc.Inventor: Chungeng Chen

Patent number: 11994248Abstract: A seal clamp, such as for gas lines, includes a handle assembly having a handle, a transfer or drive assembly cooperable with the handle, and a clamping assembly including first and second claws or clamps and a seal member. The first and second claws or clamps are cooperable with the transfer assembly. The seal member is structured to seal a puncture in a gas line. Responsive to movement of the handle, the first and second claws or clamps move from an OPEN position to a CLOSED position, such as to engage a pipe and create a clamping force which forces the seal member into engagement with the pipe, such as a puncture, to seal the pipe.Type: GrantFiled: September 28, 2021Date of Patent: May 28, 2024Assignees: JS Products, Inc., GTI EnergyInventors: Chungeng Chen, Travis Cottle, Jeff Mainzer

Patent number: 11491630Abstract: A combination clamp and wrench tool includes a main body, a fixed jaw attached the main body, and a floating clamp mechanism. The floating clamp mechanism may include an adjustable jaw. The floating clamp mechanism may be attached to the main body such that the floating clamp mechanism is slidable relative to the main body towards and away from the fixed jaw. The worm gear and the rack are attached to the floating clamp mechanism. Actuation of the worm gear moves the rack linearly relative to the floating clamp mechanism. When the rack is moved to contact the fixed jaw, the combination clamp and wrench tool operates in a wrench mode, and when the rack is moved away from the fixed jaw, the combination clamp and wrench tool operates in a clamp mode.Type: GrantFiled: August 20, 2019Date of Patent: November 8, 2022Assignee: JS Products, Inc.Inventor: Chungeng Chen

Patent number: 11465219Abstract: A folding handle for a tool has a main handle having a tool head, a handle extension rotatably connected to the main handle, the handle extension rotatable between a first extended position and a second folded position relative to the main handle, and a latching mechanism having a locking pin and an actuator connected to the locking pin and movable between a first position in which the locking pin engages the handle extension, preventing movement of the handle extension relative to the main handle, and a second position in which the locking pin is disengaged from the handle extension, allowing movement of the handle extension relative to the main handle. A tool may have first and second folding handles which are movably connected to one another.Type: GrantFiled: January 28, 2021Date of Patent: October 11, 2022Assignee: JS Products, Inc.Inventor: Chungeng Chen

Patent number: 11458601Abstract: A truly one-handed operable pipe wrench is provided which includes a handle having a first end and a second end, a fixed jaw disposed at the second end of the handle, and a rotatable jaw pivotally attached to the second end of the handle. The rotatable jaw includes a first engaging end and a second driven end. A lever arm is pivotally attached to the handle. The lever arm includes a handle portion and an actuating portion. When the lever arm rotates relative to the handle, the actuating portion is in contact with the second driven end of the rotatable jaw causing the rotatable jaw to rotate relative to the second end of the handle.Type: GrantFiled: February 19, 2020Date of Patent: October 4, 2022Assignee: JS Products, Inc.Inventor: Chungeng Chen

Patent number: 11446795Abstract: A double-sided, detachable tool includes a first tool half and a second tool half. The first tool half has a first tool head on a first end, a first stepped profile on a bottom surface, and a latch protruding from the bottom surface. The second tool half has a second tool head on its first end, a second stepped profile on its bottom surface, and a latching aperture extending through the second tool half from its top side to the bottom side. The latch is inserted into the latching aperture to connect the first tool half to the second tool half and is removed from the latching aperture to detach the first tool half from the second tool half. The transitions from the stepped profiles to the seconds ends of the tool halves create a substantially flush surface therebetween.Type: GrantFiled: March 17, 2020Date of Patent: September 20, 2022Assignee: JS Products, Inc.Inventor: Chungeng Chen

Patent number: 11351659Abstract: A ratcheting wrench includes a first jaw with a first jaw insert configured to move relative to the first jaw and a first spring configured to bias the first jaw insert in a first direction. The wrench also includes a second jaw with a second jaw insert configured to move relative to the second jaw and a second spring configured to bias the second jaw insert in a second direction opposite the first direction. When the first jaw insert moves relative to the first jaw and the second jaw insert moves relative to the second jaw, a space between the first jaw and the second jaw increases. This allows the jaws of the wrench to slip over corners of a fastener to achieve a ratcheting effect.Type: GrantFiled: April 3, 2019Date of Patent: June 7, 2022Assignee: JS Products, Inc.Inventor: Chungeng Chen

Publication number: 20210347015Abstract: A removal tool is provided. The removal tool includes a wrench apparatus having a body having a handle, wherein a portion of the body is structured to engage a securing member. The removal tool also includes a locking tool assembly and a transfer assembly. The locking tool assembly has a first jaw, a second jaw coupled to the first jaw, and a handle extending from the first jaw, the first and second jaws being structured to engage a conduit. The conduit is coupled to the securing member. The transfer assembly is coupled to the handles of the wrench apparatus and the locking tool assembly in order to transfer a force therebetween, thereby allowing the securing member to be removed from the conduit.Type: ApplicationFiled: April 30, 2021Publication date: November 11, 2021Inventor: Chungeng Chen

Publication number: 20210339368Abstract: A tool, such as pliers, is configured to permit two modes or configurations of operation, such as for use in manipulating internal and external retaining rings. In one mode of operation, tool tips are moved towards one another when handles of the pliers are compressed towards one another, and in a second mode of operation, the tool tips are moved away from one another when the handles of the pliers are compressed towards one another. The modes of operation may be selected, such as by rotating a rotatable selector which controls connection of first and second handles of the pliers with first and second tool bodies.Type: ApplicationFiled: April 26, 2021Publication date: November 4, 2021Inventor: Chungeng Chen
