Abstract

Abstract A car conveyer wherein two-axle cars are arranged adjacent to each other on the horizontal sections of the track, for which purpose one axle of each car is pivotably connected through a rod to the right-hand driving chain, and the other axle - to the left-hand driving chain. Each roller mounted on the axle between the car and the rod moves on the guide located along the track. On the curved section of the track corresponding to the outer side of the sprocket engaged with the chain, the guide is constructed in such a way that it enables the cars to pass freely on that section.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 334 words
A car conveyer having straight and turn-around sections of track, comprising: a frame; two sprockets mounted parallel to each other on said frame for each of said turn-around sections of the conveyer track; two driving chains mounted on said sprockets, one driving chain being a right-hand chain and the other driving chain being a left-hand chain according to the direction of travel; load-carrying cars located between said driving chains and having two axles spaced lengthwise of said car, said axles connecting said cars with said chains, so that one axle is connected with said right-hand driving chain and the other axle is connected with said left-hand chain; rods for linking said car axles with said driving chains, one end of each rod being pivotably connected with the respective axle of the car, the end of each rod being connected to the respective driving chain, said sprockets of said driving chains being installed on each turnaround section of the track so that their axes are displaced with respect to one another by an amount equal to the distance between said axles of said cars; rollers, each of which is mounted on a respective axle of the car; linear guides having straight and curved sections fastened to said frame along the track, for moving said rollers and establishing the trajectory of the axle of the car, the guides on each said turn-around section of the track corresponding to the outer side of the sprocket engaged with the respective driving chain and being located outside the area confined by the sides of an imaginary rhombus, one diagonal of said rhombus extends from the geometrical center of the car axle at the point where the straight section of the guide passes into the curved section through the geometrical center of the sprocket, said one diagonal being equal to the double height of said car when loaded, the other diagonal of said rhombus being equal to the double length of said car; and driving means for driving said chains.
Claim 2
Dependent Claim 334 words
A car conveyer having straight and turn-around sections of track, comprising: a frame; two sprockets mounted parallel to each other on said frame for each of said turn-around sections of the conveyer track; two driving chains mounted on said sprockets, one driving chain being a right-hand chain and the other driving chain being a left-hand chain according to the direction of travel; load-carrying cars located between said driving chains and having two axles spaced lengthwise of said car, said axles connecting said cars with said chains, so that one axle is connected with said right-hand driving chain and the other axle is connected with said left-hand chain; rods for linking said car axles with said driving chains, one end of each rod being pivotably connected with the respective axle of the car, the end of each rod being connected to the respective driving chain, said sprockets of said driving chains being installed on each turnaround section of the track so that their axes are displaced with respect to one another by an amount equal to the distance between said axles of said cars; rollers, each of which is mounted on a respective axle of the car; linear guides having straight and curved sections fastened to said frame along the track, for moving said rollers and establishing the trajectory of the axle of the car, the guides on each said turn-around section of the track corresponding to the outer side of the sprocket engaged with the respective driving chain and being located outside the area confined by the sides of an imaginary rhombus, one diagonal of said rhombus extends from the geometrical center of the car axle at the point where the straight section of the guide passes into the curved section through the geometrical center of the sprocket, said one diagonal being equal to the double height of said car when loaded, the other diagonal of said rhombus being equal to the double length of said car; and driving means for driving said chains.
Claim 3
Dependent Claim 91 words
A car conveyer as set forth in claim 1, wherein, the trajectory of the car axle established by the guide on the curved section of the track corresponding to the outer side of the sprocket engaged with the driving chain, forms part of the circle having its center coinciding with the geometrical center of the sprocket, the radius of said circle being at least equal to the length of the car, when the height of the car with the load and the length of the car are of the same size.
Claim 4
Dependent Claim 157 words
A car conveyer as set forth in claim 1 wherein the curved section of the guide passes into the straight section on the turn-around section of the track and crosses the plane passing through the driving chains in a crossing line, the configuration and the size of the trajectory of the car axle established by the section of the guide lying between said crossing line and the point where the curved guide passes into the straight one, being identical with the configuration and size of the trajectory of the car axle established by the section of the guide located between the extension of the rhombus diagonal extending through the geometrical centers of the roller, sprocket and said crossing line, the curved section of the guide being located at the outer side of the sprocket engaged with the chain, the centers of curvature of the curved sections lying on opposite sides of the trajectory of the car axle.
Claim 5
Dependent Claim 151 words
A car conveyer as set forth in claim 2, wherein the curved section of the guide on the turn-around section of the track passes into the straight section and crosses the plane passing through the driving chains in a crossing line, the configuration and the size of the trajectory of the car axle established by the guide section lying between said crossing line and the point where the curved section of the guide passes into the straight section, being identical to the configuration and size of the trajectory of the car axle established by the guide section lying between the rhombus diagonal extending through the geometrical centers of the roller and the sprocket and said crossing line, the guides being located at the outer side of the sprocket engaged with the chain, the centers of curvature of the curved sections lying on opposite sides of the trajectory of the car axle.
