Filed:

Mar 16, 2022

Appl. No.:

17/696439

Inventors:

- Chicago IL, US
Richard Kyle Warren - Columbia IL, US

Assignee:

Amsted Rail Company, Inc. - Chicago IL

International Classification:

B61F 5/26

Abstract:

An adapter assembly of a vehicle includes a bearing adapter configured to physically contact a bearing on an axle of the vehicle, and an adapter pad nested within an opening of a side frame of the vehicle and secured to at least one thrust lug of the side frame. The adapter pad includes a base section and legs depending from the base section. The legs are compressed between the at least one thrust lug of the side frame and shoulders of the bearing adapter to exert frictional forces on the shoulders of the bearing adapter. A combination of the frictional forces exerted by the adapter pad on the bearing adapter is less than a weight of the bearing adapter, such that as the side frame rises away from the bearing during movement of the vehicle, the adapter pad rises relative to the bearing adapter.

Inventors:

Richard Warren - Rowlett TX, US

International Classification:

B25B 27/02

Abstract:

Current EvoPEX connector fittings offer numerous advantages over brass fitting counterparts. However, EvoPEX connector fitting's non-removable design can lead to increased labor and costs. The proposed removal tool is designed to remove push-to-connect fittings from various fluid conduits and includes an external malleable clamping flange and an internal metallic release sheet, adaptable for sealing engagement with a fluid conduit outer wall. Once the metallic release sheet circumscribes the appropriate, fluid conduit, the user pivotally slides the conduit removal tool laterally toward the EvoPEX connector fitting. Insertion of the metallic release sheet between the fluid conduit and the EvoPEX connector fitting depresses the internal locking collar. This depression mechanism prevents structural damage to PEX fluid conduit, thereby permitting reuse of the associated fluid conduit as not previously possible. Once inserted, the user may mechanically decouple the EvoPEX connector fitting from the fluid conduit through manual separation.

Inventors:

- Chicago IL, US
Richard Warren - Columbia IL, US

International Classification:

B61D 17/16

Abstract:

The present railway car hatch cover latch assembly includes a latch plate. One end of the latch assembly rod is affixed to a bracket, with the adjustable end usually comprising an eye at the end of a threaded shaft. The threaded shaft is received in a keeper. The keeper in turn supports and holds a coil spring between the eye and the keeper cap. A bent hooking rod has two upturned ends that hold the end of the coil spring nearest the eye. The center of the bent hooking rod extends from the keeper to form a receiver. A latch plate includes a pivot rod that extends through the receiver of the bent hooking rod. The latch paddle itself contacts and holds the hatch cover is a compressively closed position against the railway car hatch ring.

Richard Warren - Columbia IL, US

International Classification:

E06B 7/02
E06B 7/16
B61D 49/00

Abstract:

A railway car hatch cover assembly is provided comprising an outer hatch cover, and a gasket retainer. A venting gasket is provided comprised of mesh venting material, and a hydrophobic coating is applied to the mesh venting material. The venting gasket forms a seal with the outer hatch cover and the hatch ring coaming. The hydrophobic coating is usually applied to an outer surface of the mesh venting material. The mesh venting material allows the passage of air therethrough, while providing a barrier to the passage of dirt or similar debris.
