Patent number: 9663092Abstract: A device for monitoring the status of a railcar handbrake having a hand operated handle, which device has a load bearing member configured to be inserted in the linkage of a railcar handbrake system so that the force applied to the brake system passes through the load bearing member. A strain gauge mounted on the load bearing member measures the strain. The information from the strain gauge is indicative of the force applied by the handbrake to the brake and is used to determine the status of the handbrake. Means for determining motion of the railcar is also provided. In one form, if it is determined that the brake is on and the railcar is in motion, information, such as an alarm, is transmitted. A system and method of monitoring a railcar handbrake are also provided.Type: GrantFiled: April 13, 2015Date of Patent: May 30, 2017Assignee: Amsted Rail Company, Inc.Inventors: Andrew Martin, Jeevan Robinson, Wayne Murphy

Patent number: 9446774Abstract: A three piece railway freight truck is comprised of two laterally spaced side frames between which a bolster extends. Suspension load springs support the bolster, and control springs support friction shoes. Both variations of friction shoes have gaps that will allow lateral movement of the friction shoes across the bolster or the friction shoes across the side frame. The lateral movement is accomplished by having a low friction material pad between the bolster and the friction shoe or a low friction material pad between the friction shoe and a wear plate that bears on the side frame. The low friction material with low siding resistance allows lateral displacement energy to be dissipated over the lateral decoupling clearance.Type: GrantFiled: September 2, 2014Date of Patent: September 20, 2016Assignee: Amsted Rail Company, Inc.Inventor: Paul Steven Wike

Patent number: 9212489Abstract: A guard assembly for a skylight. The assembly includes rails positioned on opposing sides of a skylight frame, connected by tension members that act to pull the rails laterally toward each other, causing the rails to clamp onto the skylight frame. The assembly can be coupled to the skylight without need for penetration fasteners that can cause the skylight to leak. The rails and tension members can be custom sized to proper dimension at a work site. In one embodiment, the guard assembly includes modular reinforcement components that spread out local clamping forces over a large area to mitigate the generation of yield and creep stresses that would otherwise cause the guard assembly to loosen over time. The guard assembly includes a guard structure that extends over the skylight and, in various embodiments, can be readily removed from the guard assembly for servicing of the skylight.Type: GrantFiled: April 9, 2015Date of Patent: December 15, 2015Assignee: Safety Rail Company, LLCInventor: Craig Erickson

Patent number: 9150226Abstract: Mounting rings and methods for mounting structures to shafts are provided. The rings and methods may be used to mount other rings or housings to a shaft. The rings are characterized by having flexible inner diameters that can deflect under a radial load. The radial deflection of the inner diameter permits the rings to deflect and engage an outer diameter of a shaft. The engagement of the rings with a shaft provides at least some resistance to movement, for example, rotation and/or axial displacement, of the shaft relative to the ring and structure. In one aspect, the ring has a closed, hollow, construction, for example, a circular, oval, or polygonal closed, hollow construction. The ring may include a plurality of indentations, such as slots, on the inside diameter of the ring that may relieve at least some of the circumferential stress in the ring. Methods for using the rings to mount a structure to a shaft are also disclosed.Type: GrantFiled: June 26, 2009Date of Patent: October 6, 2015Assignee: Amsted Rail Company, Inc.Inventors: John E. Rode, Sean E. Strait

Patent number: 8991318Abstract: A stabilized railway car truck consists of two side frames and a holster. The bolster has laterally opposite ends, each end extending into and supported within a side frame opening on a spring group. The stabilized railway car truck also includes a transom extending into, and supported within, a side frame opening. The spring group is supported at each transom end. Each side frame has a pedestal opening at each end that receive a rotating lug to accept a elastomeric steering pad and bearing adapter. The attachment of the side frames and transom is a rigid pivotal connection. Friction shoes between the side frames and bolster provide damping of an initial low to a high rate friction once engaged. The pivotal decoupling of the side frame and transom, and the lateral movement of the friction shoes to the bolster, eliminates track displacement irregularities from reacting at the bolster and into the vehicle.Type: GrantFiled: March 15, 2013Date of Patent: March 31, 2015Assignee: AMSTED Rail Company, Inc.Inventors: Paul Steven Wike, Aleynikov Igor Arkadyevich
