Abstract

Abstract A car intended to be used on a railroad for the carrying of materials and including a frame on which a pair of outwardly swinging box-like hoppers are pivotally mounted longitudinally thereof for outward movement relative to each other to dump the contents of the hoppers on opposite sides of the track, the hoppers being controlled and operated either independently or simultaneously at the selection of the individual operating the same by a control of the hydraulic mechanism effecting the dumping action.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 358 words
A railroad dumping car of the type having a mounting platform supported on railroad trucks for guided movement along conventional railroad tracks, the dumping car comprising: a pair of longitudinally extending rectangularly shaped open topped box-like hoppers each having a content receiving compartment formed therein adapted to carry the same or different contents entirely separate from each other, the hoppers disposed in side-by-side adjacent relationship with each hopper having opposed end wall surfaces; a pair of side-by-side aligned brackets disposed on each side of said platform adjacent each associated end of said associated hopper and extending upwardly from said platform; each mounting bracket having a bearing assembly mounted at the top portion thereof; each hopper having a pair of axially aligned trunnions affixed to opposite end wall surfaces of the hopper and projecting outwardly therefrom and adapted to be rotatably received in an associated bearing for rotative support of said hopper thereabout; an upright vertically extending guiding post disposed intermediate adjacent ends of said hoppers and having one end affixed to said platform with said posts projecting upwardly therefrom, a pair of horizontally spaced apart vertically extending slots formed in a side member of said post; a pair of hydraulic cylinders and piston arrangements, each of said arrangements associated with one of said guiding post slots and disposed inwardly of said guiding posts, each of said piston rods having its free end disposed in alignment with the associated slot and reciprocally movable therealong between the top and bottom ends of said slot; hydraulic means connected to said cylinders to effect the operation thereof; control means associated with said hydraulic means and selectable for the independent or simultaneous operation of said hydraulic means; and linkage means interconnecting each of said free ends of said piston rods to one of said hopper trunnions to effect the tilting rotation of said associated hopper about its axis when said piston rod moves upwardly along said slot to the top end of the slot and wherein said hopper is returned to its initial position upon said piston rod moving downwardly of said slot to its initial position adjacent the bottom of said slot.
Claim 2
Dependent Claim 358 words
A railroad dumping car of the type having a mounting platform supported on railroad trucks for guided movement along conventional railroad tracks, the dumping car comprising: a pair of longitudinally extending rectangularly shaped open topped box-like hoppers each having a content receiving compartment formed therein adapted to carry the same or different contents entirely separate from each other, the hoppers disposed in side-by-side adjacent relationship with each hopper having opposed end wall surfaces; a pair of side-by-side aligned brackets disposed on each side of said platform adjacent each associated end of said associated hopper and extending upwardly from said platform; each mounting bracket having a bearing assembly mounted at the top portion thereof; each hopper having a pair of axially aligned trunnions affixed to opposite end wall surfaces of the hopper and projecting outwardly therefrom and adapted to be rotatably received in an associated bearing for rotative support of said hopper thereabout; an upright vertically extending guiding post disposed intermediate adjacent ends of said hoppers and having one end affixed to said platform with said posts projecting upwardly therefrom, a pair of horizontally spaced apart vertically extending slots formed in a side member of said post; a pair of hydraulic cylinders and piston arrangements, each of said arrangements associated with one of said guiding post slots and disposed inwardly of said guiding posts, each of said piston rods having its free end disposed in alignment with the associated slot and reciprocally movable therealong between the top and bottom ends of said slot; hydraulic means connected to said cylinders to effect the operation thereof; control means associated with said hydraulic means and selectable for the independent or simultaneous operation of said hydraulic means; and linkage means interconnecting each of said free ends of said piston rods to one of said hopper trunnions to effect the tilting rotation of said associated hopper about its axis when said piston rod moves upwardly along said slot to the top end of the slot and wherein said hopper is returned to its initial position upon said piston rod moving downwardly of said slot to its initial position adjacent the bottom of said slot.
Claim 3
Dependent Claim 160 words
The dumping car as set forth in claim 1 wherein said linkage means comprises a pair of horizontal arm members, each arm member having one end associated with one of the slots with the opposite end projecting normal to the plane of the slot, the horizontal arms projecting in opposite directions from said slots, each opposite end of each of said horizontal arms having an elongated longitudinally extending slot formed therein and extending therethrough, a pair of angle arm, each angle arm associated with one of said hopper cars, each angle arm having one end affixed to an adjacent trunnion of the associated hopper car with the opposite end extending outwardly therefrom in a direction toward said guide post to be pivotally joined by a pivot pin to said slot of an associated horizontal arm member for horizontal movement therethrough upon vertical reciprocal movement of said arm member along said associated slot to effect the dumping action of said hopper.
Claim 4
Dependent Claim 26 words
The dumping car as set forth in claim 2 wherein said trunnions are disposed approximately along the axis of the center of gravity of each hopper.
Claim 5
Dependent Claim 42 words
The dumping car as set forth in claim 3 wherein said mounting brackets are of an A-shaped configuration having the base portion thereof mounted to the top surface of said platform and having said bearing assembly mounted at the apex portion thereof.
