Appl. No.:

09/947239

Inventors:

George S. Creighton - Flower Mound TX

Assignee:

TRN Business Trust - Dallas TX

International Classification:

E02F 928

US Classification:

37456

Abstract:

The present invention includes a primary retainer pin having an internal secondary retainer pin operable to couple the primary retainer pin with an adapter for use with excavation equipment components. A removable tooth having first and second tooth sides is coupled with the adapter and at least partially covers the first adapter end. A central portion of the adapter defines an elongate slot which extends from a first adapter side to a second adapter side. First and second tooth sides include first and second openings, respectively, configured such that the first and second openings are aligned with an imaginary longitudinal axis of the elongate slot while the removable tooth is coupled with the adapter. The primary retainer pin extends at least partially through the first and second openings, and the elongate slot, to couple the removable tooth and the adapter. The secondary retainer pin engages the adapter, adjacent a recessed cavity which extends from the elongate slot, to limit movement of the primary retainer pin along the imaginary longitudinal axis.

US Classification:

105247

Abstract:

A railcar with longitudinal discharge openings is disclosed. In one embodiment, the railcar includes an underframe, a pair of sidewall assemblies and a hopper formed between the sidewall assemblies. The underframe has a center sill and a pair of side sills. The center sill disposed between the pair of side sills along a generally longitudinally axis of the railcar. The hopper includes a discharge opening adjacent to the center sill. A respective discharge door assembly disposed adjacent to each discharge opening to control flow of lading from each hopper. Each discharge door may hinge from the center sill for movement between a first position and a second position relative to the discharge openings.

US Classification:

105404, 105409, 105355, 105423

Abstract:

A universal boxcar is provided with load carrying capabilities of a conventional uninsulated boxcar and temperature ratings of an insulated boxcar. The insulated boxcar may be formed with interior dimensions corresponding generally with interior dimensions of an uninsulated boxcar without requiring the use of high cost, high performance insulation. The insulated boxcar may be formed at a reasonable cost and selling price with increased load carrying capacity, increased service life, and reduced maintenance costs as compared to conventional insulated boxcars.

Abstract:

A universal boxcar is provided with exterior metal surfaces and load carrying capabilities of a conventional uninsulated boxcar and thermal transfer ratings of an insulated boxcar. The boxcar may be formed with interior dimensions corresponding generally with interior dimensions of an uninsulated boxcar without high cost, high performance insulation. The boxcar may include a double side doors slidably mounted on the exterior of each sidewall assemble. A load restraint system may be provided with improved load carrying capabilities and performance characteristics. The load restraint system may have increased load carrying capacity, increased service life, and reduced maintenance costs. All or portions of the load restraint system may be used in uninsulated boxcars or temperature controlled railway cars.

US Classification:

105286

Abstract:

Hopper cars both open and covered and discharge control systems are disclosed. Each hopper car may include at least one hopper and a center sill which defines in part a longitudinal axis of the hopper car. At least one discharge opening may be formed proximate a lower portion of each hopper. A respective door assembly may be pivotally mounted adjacent to each discharge opening to control the flow of lading from the respective discharge opening. Each discharge control system may include a common linkage and associated secondary linkages operable to move associated door assemblies between a first position and a second position. A power source including a motor, an air cylinder or a hydraulic cylinder may be disposed on the railway car to move the common linkage. For other hopper cars a wayside drive system may be releasably engaged with a capstan operable coupled to the common linkage.
