Patent number: 10415598Abstract: A pump features a bearing sleeve couples to a pump shaft, and includes a bearing sleeve surface having bores for receiving fasteners; and an adjusting nut having a central bore with central bore threads to rotationally couple to pump shaft threads, is configured to rotate in relation to the bearing sleeve and move the pump shaft axially to adjust an impeller clearance between a working side of an impeller arranged on the pump shaft and a casing of the pump, and is configured with an adjusting nut surface having openings different in number than the bores, sets of corresponding bores and openings aligning at angular adjustment intervals, e.g. every 9 or 15°, when the adjusting nut is rotated in relation to the bearing sleeve in either direction in order to receive fasteners to couple the adjusting nut to the bearing sleeve when the adjustment of the impeller clearance is completed.Type: GrantFiled: April 3, 2017Date of Patent: September 17, 2019Assignee: ITT MANUFACTURING ENTERPRISES LLCInventors: Jason D. Peckham, Mark A. Playford

Publication number: 20150329127Abstract: A coupler for a railway vehicle includes a coupler anchor and a coupler centering device having a pair of arm sub-assemblies. Each arm subassembly has an upper centering arm connected to a lower centering arm via a torsion bar extending through the coupler anchor. The lower centering arms are connected by a cross link such that movement of one of the upper centering arms causes a corresponding movement of both of the lower centering arms. Each upper centering arm engages a roller that rolls along a curved surface of the centering arm when the coupler is rotated horizontally toward the upper centering arm. A centering stop element prevents the movement of the opposing upper centering arm to generate a restoring force in the torsion bars that facilitates horizontal movement of the coupler. The coupler centering device may be disengaged from an active centering position to facilitate servicing of the coupler.Type: ApplicationFiled: October 28, 2013Publication date: November 19, 2015Applicant: WABTEC HOLDING CORP.Inventors: Jason D.

Patent number: 8960464Abstract: A coupler for transit cars includes a coupler anchor, a coupler mechanism supported to the coupler anchor by a deformation tube and draft gear element, and a coupler support mechanism. The coupler support mechanism includes two support arms pivotally mounted to a lower part of a coupling connector. A tension rod is provided for each support arm to control the pivotal displacement of each support arm. Each support arm further includes a torsion spring which is loaded as the support arm is pivotally displaced in an upward direction and unloaded as the support arm is pivotally displaced in a downward direction. The position of each support arm may be adjusted independently, thereby allowing adjustment of the coupler along longitudinal and lateral planes of the transit car.Type: GrantFiled: April 3, 2012Date of Patent: February 24, 2015Assignee: Wabtec Holding Corp.Inventor: Jason D. Peckham

Patent number: 8714377Abstract: An energy absorbing coupler for railway vehicles includes a coupler anchor, a coupler mechanism supported to the coupler anchor by a deformation tube and draft gear element, and a plurality of energy absorbing devices associated with the coupler anchor. The energy absorbing devices each include two mating components in frictional engagement with one another. Sliding movement between contacting surfaces of the two components occurs when energy is applied to the coupler mechanism, thereby creating friction and dissipating the applied energy at least in part in the form of heat. The two mating components may include a male part, such as a mounting bolt, in mating engagement within a female part, such as a collar. An inside diameter of the collar may be slightly smaller than an outside diameter of the mounting bolt to create a press-fit engagement.Type: GrantFiled: January 31, 2012Date of Patent: May 6, 2014Assignee: Wabtec Holding Corp.Inventor: Jason D. Peckham

Patent number: 8616389Abstract: A mating cam coupler device includes a coupler head having a first lateral portion and a second lateral portion. A male cam is associated with the first lateral portion. A male cam locking mechanism is disposed within the first lateral portion and is operably connected with the male cam. A female cam is associated with the second lateral portion. A female cam locking mechanism is disposed within the second lateral portion and is operably connected with the female cam. The male cam is positioned to engage the female cam of an opposing coupler and the female cam is positioned to engage the male cam of the opposing coupler and operation of the male cam locking mechanism is triggered by engagement of the male cam with the opposing female cam and operation of the female cam locking mechanism is triggered by engagement of the female cam with the opposing male cam.Type: GrantFiled: May 10, 2012Date of Patent: December 31, 2013Assignee: Wabtec Holding Corp.Inventor: Jason D.
