Abstract

Abstract A transfer conveyer for a monorail-supported slurry transportation system has a bottom frame which is formed through a 180° arc. An input ramp and an output ramp and rollers are radially journaled along the bottom frame. The side frames are constructed around the bottom frame, and a plurality of rollers is journaled in the side frame. A transport system is attached to the frames, and an apparatus is attached between the transport system and the frame to change the angle of the bottom frame with respect to the horizon. The input and output ramps are also pivotally attached to the frame in order that they may be swung horizontally with respect to the frame to properly align the input and output ramps with the overhead monorail transportation system.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 121 words
In a conveyer for transporting a slurry hose means supported from an overhead monorail through a 180° turn wherein said conveyer has a bottom frame means formed through a 180° arc and an input ramp and an output ramp, and first roller means radially journaled along said bottom frame, said conveyer comprising: a. first and second side frame means pivotally attached to each side of said bottom frame means to permit said side frame means to swing angularly with respect to the axis of said overhead monorail; b. a plurality of second roller means journaled in said first and second side frame means; and c. means for changing the distance between said bottom frame first roller means and said overhead monorail.
Claim 2
Dependent Claim 121 words
In a conveyer for transporting a slurry hose means supported from an overhead monorail through a 180° turn wherein said conveyer has a bottom frame means formed through a 180° arc and an input ramp and an output ramp, and first roller means radially journaled along said bottom frame, said conveyer comprising: a. first and second side frame means pivotally attached to each side of said bottom frame means to permit said side frame means to swing angularly with respect to the axis of said overhead monorail; b. a plurality of second roller means journaled in said first and second side frame means; and c. means for changing the distance between said bottom frame first roller means and said overhead monorail.
Claim 3
Dependent Claim 69 words
An apparatus as disclosed in claim 1 additionally including a transportation means attached to said conveyer whereby said conveyer can be moved along the length of and under said overhead monorail and wherein said means for changing the distance between said bottom frame first roller means and said overhead monorail comprises a hydraulic piston and means for attaching said hydraulic piston between said transportation system and said bottom frame.
