Patent number: 10118630Abstract: A truck mounted braking system is provided with a mechanical pivot adjustment on a lever connected to the brake actuator to permit the braking force applied to the wheels to vary depending on the lading condition of the car, without involving additional pneumatic elements such as a pneumatic empty load device. The system adjusts the braking force applied when the hand brake is activated, even when the railway car is disconnected from the pneumatic brake line.Type: GrantFiled: July 26, 2017Date of Patent: November 6, 2018Assignee: STRATO, INC.Inventor: Jonathan Sunde

Patent number: 9956968Abstract: The invention relates to a railway car truck incorporating an interconnection between a side frame and a bearing adapter. The bearing adapter may receive a reduced coefficient of friction surface member in a recess on a top surface of the bearing adapter, facilitating a reduced lateral spring rate of the wheelset. Alternatively, or in combination, an adapter plate is received in the pedestal jaw on the bearing adapter to retain the reduced coefficient of friction surface member above or below the adapter plate. The adapter plate may be provided with surfaces about perpendicular to the longitudinal and lateral axes of the side frame to support elastomeric members, which may provide different longitudinal and lateral spring rates in response to a load applied to the truck.Type: GrantFiled: December 19, 2014Date of Patent: May 1, 2018Assignee: STRATO, INC.Inventors: David Yuh-Shyang Lin, Thomas J. Heyden, Thomas R. Berg, Christopher J. Clark, Kevin P. McGarvey

Patent number: 9951887Abstract: A pipe clamp wedge is disclosed that can be used with an existing pipe clamp anchor to secure a brake line pipe to a rail car. The wedge has a cradle portion having a concave side receiving the pipe, and a convex wedge side opposite the concave side. The cradle portion has a height increasing in a longitudinal direction, and a pair of opposed channels on lateral sides of the wedge are adapted to receive tabs on the pipe anchor. A pair of tabs on the wedge extends in the opposite direction from the tabs on the pipe anchor on either side of the cradle portion. Thus, the wedge can be slid onto the anchor, tightening around the pipe as the wedge moves in the longitudinal direction onto the anchor, and the wedge is dimensioned so that when the wedge cannot move further, the tabs on the wedge extend beyond the pipe anchor and may be bent up (toward the railcar) to secure the wedge. The parts of the combination are adapted so that sliding the pipe onto the anchor and bending the tabs may be done with a hammer.Type: GrantFiled: April 21, 2016Date of Patent: April 24, 2018Assignee: STRATO, INC.Inventors: Michael J. Foxx, Zhen Liu, Jennifer Mak, Larry Hixon

Patent number: 9694832Abstract: A coupler head and mounting bracket combination for supporting a brake hose fitting uses a lug formed integrally with the coupler head and a support bracket mating with the lug. In embodiments, the bracket may be installed in a plurality of vertical positions on the coupler head. The bracket is maintained in a position inboard of the lateral side of the coupler head, to reduce or eliminate the likelihood that the bracket will interfere with the other equipment or the car body. Embodiments of the invention are particularly adapted for “E” type and “F” type coupler heads.Type: GrantFiled: September 22, 2015Date of Patent: July 4, 2017Assignee: Strato, Inc.Inventors: Michael J. Foxx, Jason Reiling, Kevin P. McGarvey, George Vermesi

Patent number: 9637142Abstract: A system for preventing manway cover gasket over-compression utilizes machined surfaces on the top of eye bolt lugs on the side of a manway nozzle, machined compression stops on the periphery of the cover, and a specified distance between the top of the eye bolt lug and the manway nozzle edge to engage the stops at a predetermined amount of gasket compression. Force is distributed over an increased contact surface area between the manway cover and the bolt lugs to ensure that deformation occurs preferentially in the eye bolts before any other component in the manway cover system.Type: GrantFiled: June 4, 2015Date of Patent: May 2, 2017Assignee: STRATO, INC.Inventors: Jason Reiling, Jennifer Mak, Michael Serra

Patent number: 8893626Abstract: A railway car truck incorporating an interconnection between the side frame and bearing adapter is characterized by a low lateral spring constant relative to the longitudinal spring constant. The interconnection provides a proportional restoring force with minimal internal friction and hysteresis. In embodiments, the interconnection comprises compressed elastomeric members positioned between the thrust lug of the side frame and the bearing adapter in the longitudinal direction and a low friction interface between the roof of the pedestal jaw and the top of the bearing adapter.Type: GrantFiled: August 31, 2012Date of Patent: November 25, 2014Assignee: STRATO, Inc.Inventors: Thomas R. Berg, George Currier, Larry Hixon, Kevin McGarvey, Jason Reiling
