Abstract
Abstract A system for conveying molded bricks known as briquettes from a press to a bed plate wherein the briquettes are each conveyed by a plurality of spaced parallel belts to above a conveyor which carries the bed plates under the briquettes supported by the conveyor belts. An inclined substantially coplanar conveyance track which includes elongated rollers has its after portion periodically raised whereby the rollers located in the after portion penetrate upwardly between the belts carrying the briquettes thus lifting the briquettes from the belt. A removal mechanism pushes the briquettes down the rollers of the conveyance track onto a removal plate which pivots with the conveyance track and extends therefrom at a slight incline, the briquettes being received by the main conveyor carrying the bed plates whereby the briquettes are pushed over the conveyance track and onto the bed plate. The removal mechanism is reciprocating and the main conveyor moves intermittently and simultaneously with the removal mechanism except, preferably, the removal mechanism stops slightly before the main conveyor stops which provides an interval between rows of briquettes received on the bed plates.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
180 words
An apparatus for conveying briquettes which have been formed in a press to bed plates, the apparatus comprising: a first conveyor for carrying said briquettes; a second main conveyor under said first conveyor disposed at right angles thereto, said first conveyor comprising a plurality of parallel longitudinal spaced conveying means with at least one interval therebetween; a substantially coplanar conveyance track provided with pivot means proximate its forward end and adapted to be inclined relative to said second conveyor, said conveyance track comprising a frame which supports a plurality of substantially coplanar roller means, a removal plate and vertical moving means provided therefor, said frame including said pivot means, said removal plate being provided with hinge means in its after part which connects it to said frame, said roller means being capable of being vertically raised in said interval to lift said briquettes from said first conveyor, the inclination of said conveyance track relative to said second conveyor being such whereby briquettes may be moved down the incline of said conveyance track from said first conveyor to said second conveyor.
Claim 2
Independent Claim
180 words
An apparatus for conveying briquettes which have been formed in a press to bed plates, the apparatus comprising: a first conveyor for carrying said briquettes; a second main conveyor under said first conveyor disposed at right angles thereto, said first conveyor comprising a plurality of parallel longitudinal spaced conveying means with at least one interval therebetween; a substantially coplanar conveyance track provided with pivot means proximate its forward end and adapted to be inclined relative to said second conveyor, said conveyance track comprising a frame which supports a plurality of substantially coplanar roller means, a removal plate and vertical moving means provided therefor, said frame including said pivot means, said removal plate being provided with hinge means in its after part which connects it to said frame, said roller means being capable of being vertically raised in said interval to lift said briquettes from said first conveyor, the inclination of said conveyance track relative to said second conveyor being such whereby briquettes may be moved down the incline of said conveyance track from said first conveyor to said second conveyor.
Claim 3
Dependent Claim
25 words
An apparatus in accordance with claim 1 wherein the axis of rotation of said pivot means is substantially at the level of said second conveyor.
Claim 4
Dependent Claim
23 words
An apparatus in accordance with claim 2 wherein said second conveyor carries bed plates adapted to receive said briquettes from said conveyor track.
Claim 5
Dependent Claim
49 words
An apparatus in accordance with claim 1 wherein a removal mechanism is adapted to move said briquettes along said conveyance track when said roller means are in a raised position supporting said briquettes, said mechanism moving said briquettes from their location on said roller means above said first conveyor.
Claim 6
Independent Claim
207 words
A method of conveying briquettes which have been formed in a press to bed plates which comprises the steps of performing the function of: conveying said briquettes on a first conveyor to a location above a second conveyor carrying said bed plates; placing a substantially coplanar conveyance track on an incline between said first conveyor and said second conveyor; causing said coplanar conveyance track to raise under said briquettes and lift them vertically from said first conveyor, and while said briquettes are so raised, transporting them on said conveyance track towards said second conveyor away from their location above said first conveyor; carrying said bed plates by said second conveyor under and proximate the lower end of said conveyance track, said bed plates being moved in the direction of said briquettes on said conveyance track, moving said briquettes down the incline of said conveyance track onto said bed plates, the moving of said bed plates and said briquettes being intermittent and simultaneous at substantially the same speed, said briquettes being moved together in rows down said conveyance track incline for shorter periods of time whereby as each said row is received by said bed plate, an interval is formed before said bed plate received the succeeding row.
Claim 7
Independent Claim
207 words
A method of conveying briquettes which have been formed in a press to bed plates which comprises the steps of performing the function of: conveying said briquettes on a first conveyor to a location above a second conveyor carrying said bed plates; placing a substantially coplanar conveyance track on an incline between said first conveyor and said second conveyor; causing said coplanar conveyance track to raise under said briquettes and lift them vertically from said first conveyor, and while said briquettes are so raised, transporting them on said conveyance track towards said second conveyor away from their location above said first conveyor; carrying said bed plates by said second conveyor under and proximate the lower end of said conveyance track, said bed plates being moved in the direction of said briquettes on said conveyance track, moving said briquettes down the incline of said conveyance track onto said bed plates, the moving of said bed plates and said briquettes being intermittent and simultaneous at substantially the same speed, said briquettes being moved together in rows down said conveyance track incline for shorter periods of time whereby as each said row is received by said bed plate, an interval is formed before said bed plate received the succeeding row.
Claim 8
Dependent Claim
19 words
A method in accordance with claim 5 wherein said conveyance track is reciprocated vertically relative to said first conveyor.
Claim 9
Dependent Claim
33 words
A method in accordance with claim 6 wherein said first conveyor is provided with slots, parts of said conveyance track being raised through said slots to lift said briquettes from said first conveyor.
