Abstract
Abstract An apparatus for transferring or conveying refuse or other materials is disclosed herein as used in conjunction with a refuse disposal system. Normal refuse is dumped into a pit or storage area at the bottom of which is located the conveying apparatus. Large or extremely bulky refuse can be first transferred to a shearing device and then dropped into the pit onto the conveyor. The conveyor includes a plurality of superimposed upwardly inclined pusher rams which are individually operable as by hydraulic cylinders. The rams include a pusher plate mounted on a movable enclosed carriage. A cover deck guards each ram in its retracted position. Means are provided to readily remove each ram assembly without disturbing the overall continuity of the system in the event repair or replacement is needed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
146 words
In a system for handling refuse material and the like, a pit for storing the material, said pit having an open top, downwardly converging side walls, and a trough meeting said side walls at their closest point of convergence; said trough including two generally vertical side plates; columns supporting said side plates; a plurality of adjacent upwardly angled support members each supported by said columns and defining the bottom of said trough; a cylinder mounted on each said support member; a piston and piston rod in each said cylinder; a carriage having wheels riding on each said support member; and pusher means mounted on said carriage and connected to said piston rod for moving material from one said support member to an adjacent said support member in an upwardly angled direction to avoid bridging of the material between the generally vertical side plates of said trough.
Claim 2
Dependent Claim
146 words
In a system for handling refuse material and the like, a pit for storing the material, said pit having an open top, downwardly converging side walls, and a trough meeting said side walls at their closest point of convergence; said trough including two generally vertical side plates; columns supporting said side plates; a plurality of adjacent upwardly angled support members each supported by said columns and defining the bottom of said trough; a cylinder mounted on each said support member; a piston and piston rod in each said cylinder; a carriage having wheels riding on each said support member; and pusher means mounted on said carriage and connected to said piston rod for moving material from one said support member to an adjacent said support member in an upwardly angled direction to avoid bridging of the material between the generally vertical side plates of said trough.
Claim 3
Dependent Claim
36 words
In a system according to claim 1, said pusher means including pusher head means to contact the material upon movement of said carriage, and means to removably mount said pusher head means to said piston rod.
Claim 4
Dependent Claim
23 words
In a system according to claim 2, a gallery area below said support members to receive said carriage and said cylinder for maintenance.
Claim 5
Dependent Claim
24 words
In a system according to claim 3, said gallery area being kept free of material by said support members and said pusher head means.
Claim 6
Dependent Claim
22 words
A conveyor according to claim 1 further comprising means to laterally guide each said carriage as it moves along said support member.
Claim 7
Dependent Claim
220 words
A conveyor for moving material comprising a plurality of upwardly angled adjacent stationary support members, means to independently mount each said support member, each said support member including a first portion capable of receiving the material thereon and a second portion located beneath and spaced from the first portion of an adjacent support member, a carriage supported by said second portion of each said support member in the space between adjacent support members and capable of moving the material, and means to reciprocate each said carriage longitudinally from said second portion of said support member to the first portion of said support member independently to provide selective operation for each said carriage to move material from the first portion of one support member to the first portion of the adjacent support member, said means to reciprocate including a hydraulic cylinder having a piston and a piston rod, said piston moving in said cylinder from a beginning of a stroke to an end of the stroke, means to attach said piston rod to said carriage, a supply tank, a fluid in said supply tank, and means to transfer the fluid from said supply tank selectively to each side of said piston to reciprocate said piston rod, said cylinder including relief ports uncovered by said piston near the end of each stroke.
Claim 8
Dependent Claim
220 words
A conveyor for moving material comprising a plurality of upwardly angled adjacent stationary support members, means to independently mount each said support member, each said support member including a first portion capable of receiving the material thereon and a second portion located beneath and spaced from the first portion of an adjacent support member, a carriage supported by said second portion of each said support member in the space between adjacent support members and capable of moving the material, and means to reciprocate each said carriage longitudinally from said second portion of said support member to the first portion of said support member independently to provide selective operation for each said carriage to move material from the first portion of one support member to the first portion of the adjacent support member, said means to reciprocate including a hydraulic cylinder having a piston and a piston rod, said piston moving in said cylinder from a beginning of a stroke to an end of the stroke, means to attach said piston rod to said carriage, a supply tank, a fluid in said supply tank, and means to transfer the fluid from said supply tank selectively to each side of said piston to reciprocate said piston rod, said cylinder including relief ports uncovered by said piston near the end of each stroke.
Claim 9
Dependent Claim
21 words
A conveyor according to claim 6, each said carriage including a head assembly to push material along each said support member.
Claim 10
Dependent Claim
40 words
A conveyor according to claim 7 wherein said means to reciprocate includes a cylinder mounted on each said support member, each said cylinder having a piston rod, and means to removably mount said piston rod to each said head assembly.
Claim 11
Dependent Claim
22 words
A conveyor according to claim 8 including means to remove each said carriage and each said cylinder from each said support member.
