  • Patent number: 4936539
    Abstract: A support assembly is provided to support a body part, as of an automobile or other assembled article. The support assembly includes a support element on which the body part rests. The support element has a mounting plate secured on the assembly and a resilient pad portion secured to the plate. The resilient pad portion has an engagement surface which engages and supports the body part. The resilient pad portion has openings therein which soften the resilient pad portion so that relatively harder and more durable material may be used for the resilient pad portion, while still providing adequate deformation to the shape of the body part to prevent denting of the body part.

  • Patent number: 4765517
    Abstract: A railway hopper car has a pneumatic discharge structure having a throat leading to a control tube from which lading is pneumatically withdrawn. The throat is opened and closed by valve plates supported on the ends of rods extending through bearings supported in the wall of the control tube. The rods have rack structures mounted thereon operatively engaged with pinion portions of operating shafts extending parallel to the control tube. Rotation of the operating shafts causes movement of the rods and valve plates. Retainer brackets are mounted on the rack structures and include retaining portions spaced and parallel to the rack structures. The pinion portions are supported between the rack structures and the retaining portions to maintain intermeshed engagement of the pinion portions with the rack structures. Stop portions are provided on the bracket which prevent movement of the valve plates beyond the fully open and fully closed positions.

  • Patent number: 4752994
    Abstract: A scarfing apparatus for removing a weld bead from a tube being produced by a continuous method wherein the tube enters one end of a rotatable hollow spindle which supports a tool bit. The tool bit has an arcuate shape having a segment which extends 180.degree. or less about the periphery of the tube. The spindle oscillates rotationally causing the tool bit to rock back and forth across the surface of the moving tube to remove the weld bead. The tool bit is formed of carbide steel containing tantalum, titanium and cobalt. The tool bit has a forward face portion and a bottom face portion which define a tooling edge at their intersection. The bottom face portion slopes upwardly at an angle of approximately 3.degree. to reduce friction on the tube. For use with carbon steel tubing, a bit is used having a forward face portion angled approximately 15.degree. from the vertical. For use with stainless steel or aluminized material, a bit is used having a forward face portion angled back approximately 21.degree.

  • Patent number: 4745947
    Abstract: A railway tank car having a wafer-type valve arrangement is provided with a nozzle member. The nozzle member has a mounting portion mounted on the valve arrangement. The mounting portion has an inlet opening therein which is large enough to receive a portion of the wafer valve when the valve is opened. A taper portion is formed integral with the mounting portion, and an outlet portion is formed integral with the taper portion. The outlet portion is smaller than the inlet opening and has securing means thereon for attachment to standard-sized connectors for unloading liquid or semi-liquid cargo. A breakage groove is provided in the nozzle member to protect the valve arrangement from impacts. A steam heating member with steam inlet and outlet means may be placed over the smaller outlet portion and secured to the nozzle member for heating cargo passing therethrough. The taper portion has an indentation therein to facilitate heating of cargo in the nozzle member.

  • Patent number: 4741274
    Abstract: A railway hopper car has longitudinally spaced hoppers on both sides of a center sill. The hoppers have door assemblies which may be opened and closed by a door operating mechanism. The door operating mechanism includes a pneumatic cylinder which rotates a lever to move an operating rod longitudinally within the center sill. Door operating levers are rotatably supported on the railway car and pivotally connected to the operating rod to be rotated when it moves. The door operating levers are pivotally connected with struts connected with the door on the hoppers. The mechanism is configured so that all forces are substantially coplanar in a vertical plane passing through the centerline of the center sill to reduce lateral twisting forces in the mechanism. Adjustment of the length of the strut is provided for positioning of the door operating levers during assembly.

  • Patent number: 4738203
    Abstract: Air flow guide members at each end of the cargo carrying structure of an open top gondola type railway car, together with rounded transition or corner surfaces on the exterior of the car and aerodynamically shaped and oriented cross braces within the car serve to reduce aerodynamic drag on the car as it is moved. Additionally, to further enhance the energy efficiency of the car, the cargo carrying structure is formed predominantly of a light weight weldable metal, such as an aluminum alloy, and the side support members are placed on the interior wall of each side to provide a smooth, minimized air flow resistant side surface.
