Patent number: 11911888Abstract: Portable, hand held, battery operated, hydraulic tools are provided with a tool frame and one or more interchangeable working heads. When the working head is connected with the tool frame, a piston actuated by a hydraulic system within the tool frame applies force to the working head to perform a task. The tool includes a sensor for detecting the type of head connected with the tool and a mechanism for adjusting the amount of force applied to the head by the hydraulic system based on the detected head type.Type: GrantFiled: November 27, 2018Date of Patent: February 27, 2024Assignee: HUBBELL INCORPORATEDInventors: John David Lefavour, Daniel Paul Owens

Patent number: 11745322Abstract: Portable, hand held, battery operated, hydraulic tools are provided with a tool frame and one or more interchangeable working heads. When the working head is connected with the tool frame, a piston actuated by a hydraulic system within the tool frame applies force to the working head to perform a task. A coupling mechanism holds the working head to the tool frame. The coupling mechanism allows the working head to be removed from the tool frame and another working head to be joined to the tool frame. The coupling mechanism can hold the working head at a fixed rotational angle with respect to the tool frame. The coupling mechanism can also allow the working head to rotate with respect to the tool frame.Type: GrantFiled: July 19, 2022Date of Patent: September 5, 2023Assignee: Hubbell IncorporatedInventors: John David Lefavour, Thomas Romeo Faucher, Lawrence Brown, Peter Matthew Wason, Bernard P. Vachon, Sarah LaPerriere, Mark A. Chiasson

Publication number: 20230216261Abstract: Portable, hand-held, battery operated, hydraulic tools are provided with a tool frame, a force sensor, and a location detector. A piston actuated by a hydraulic system within the tool frame applies force to the working head to perform a task, such as to apply a crimp to an electrical connector. The tool determines the maximum force applied to the crimp and records that maximum force along with the geographic location of the tool when the crimp was formed. The maximum force provides an indication of the quality of the crimp and the recorded location allows a potentially defective crimp to be located.Type: ApplicationFiled: March 13, 2023Publication date: July 6, 2023Inventors: Brian McCulloh White, David Compton Heck, Michael Anthony Guarrera, John David Lefavour, Michael James Hennings

Publication number: 20230120099Abstract: Portable, hand-held hydraulic tools having a modular power unit within a handle assembly and a working head assembly mated to the handle assembly. The working head assembly can have a pair of movable jaws or a movable jaw and a fixed jaw. The jaws can be configured to perform different operating operations, such as crimping operations and cutting operations.Type: ApplicationFiled: October 17, 2022Publication date: April 20, 2023Inventors: John David LeFavour, JR., Robert D. Auger, Lawrence N. Brown, Thomas Romeo Faucher, Peter Matthew Wason

Patent number: 11590668Abstract: A portable, hand held hydraulic cutting tool having an in-line handle assembly and a working head assembly. The handle assembly has a tool frame portion and a neck portion. The working head assembly has a pair of jaw members joined so that they are movable relative to each other and held in place by a locking pin. Each jaw member has a cutting blade attached thereto. Each jaw member can be tapered and can include weight reducing pockets defined in respective sidewalls. Each jaw member includes a raised tab on an outside edge that mates with a respective tab notch in a yoke of the neck portion of the handle assembly. When the locking pin is in an extended position, the jaw members of the tool can separate and rotate away from one another until their respective locking tabs engage their respective locking tab opening, connecting the jaw members to the yoke of the neck portion of the handle assembly.Type: GrantFiled: January 21, 2021Date of Patent: February 28, 2023Assignee: HUBBELL INCORPORATEDInventors: Peter Matthew Wason, John David Lefavour

Patent number: 10965043Abstract: A set screw for connecting conductors with electrical terminals, such as a terminal block of a load panel includes a screw body and a screw face. The screw face fits inside the screw body and is movable along the axis of the screw body. An elastically deformable member, such as a coil spring or set of spring washers is disposed between the screw body and the screw face. The elastically deformable member compresses in response to force exerted between the screw body and screw face. An indicator bar is connected with the screw face and moves along the axis of the screw body along with the screw face in response to the compressive force. The proximal end of the indicator bar extends proximal of the screw body and includes one or more indicia that show the deformation of the elastically deformable member.Type: GrantFiled: September 25, 2018Date of Patent: March 30, 2021Assignee: HUBBELL INCORPORATEDInventors: John David Lefavour, Thomas Romeo Faucher
