Abstract
Abstract A batch ram feeding apparatus for feeding of material to an incinerator or other mechanism and characterized by being constructed to feed batches of comparatively equal weight regardless of variations in sizes or compositions of the material. The apparatus comprises a housing having a material receiving opening in the top and a material dispensing opening in the front and horizontally-extending upper and lower internal compartments with a communicating passageway therebetween. The apparatus further includes reciprocating rams positioned in each of the compartments and drive means for individually driving the rams to receive a batch of material in the upper compartment, compact the batch and allow it to drop into the lower compartment where it is pushed out of the dispensing opening.

A batch ram feeding apparatus for feeding of material to an incinerator or other mechanism characterized by being constructed to feed batches of comparatively equal weight regardless of variations in sizes or compositions of the material, said apparatus comprising: a generally horizontally-extending substantially enclosed hollow housing defining an opening in the top thereof for the reception of material therein to be fed from a bulk supply and an opening in the front thereof for dispensing of the material batches, and having an internal horizontally-extending parTition forming an upper horizontally-extending compartment communicating with said material receiving opening, a lower horizontally-extending compartment communicating with said material dispensing opening, and an internal passageway for the passage of material from said upper compartment to said lower compartment; a first horizontally reciprocating ram positioned in said upper compartment and a second horizontally reciprocating ram positioned in said lower compartment, said rams each having cross-sectional dimensions substantially equal to said compartments and an axial length less than the lengths of said compartments; and drive means operatively connected to said rams for individually driving said rams to move said first ram to a rearward position for the reception of material in said upper compartment from the bulk supply while maintaining said second ram in a forward position to prevent the flow of the material into said lower compartment, then moving said first ram forwardly in said upper compartment to separate a batch of material and carry the material therein to a position forwardly of said material receiving opening for closing said opening and to compact the material, then moving said second ram rearwardly allowing the compacted separated batch of material in said upper compartment to fall into said lower compartment through said internal passageway and then moving said second ram forwardly to push the compacted material in said lower compartment out of said material dispensing opening.

309 words
A batch ram feeding apparatus for feeding of material to an incinerator or other mechanism characterized by being constructed to feed batches of comparatively equal weight regardless of variations in sizes or compositions of the material, said apparatus comprising: a generally horizontally-extending substantially enclosed hollow housing defining an opening in the top thereof for the reception of material therein to be fed from a bulk supply and an opening in the front thereof for dispensing of the material batches, and having an internal horizontally-extending parTition forming an upper horizontally-extending compartment communicating with said material receiving opening, a lower horizontally-extending compartment communicating with said material dispensing opening, and an internal passageway for the passage of material from said upper compartment to said lower compartment; a first horizontally reciprocating ram positioned in said upper compartment and a second horizontally reciprocating ram positioned in said lower compartment, said rams each having cross-sectional dimensions substantially equal to said compartments and an axial length less than the lengths of said compartments; and drive means operatively connected to said rams for individually driving said rams to move said first ram to a rearward position for the reception of material in said upper compartment from the bulk supply while maintaining said second ram in a forward position to prevent the flow of the material into said lower compartment, then moving said first ram forwardly in said upper compartment to separate a batch of material and carry the material therein to a position forwardly of said material receiving opening for closing said opening and to compact the material, then moving said second ram rearwardly allowing the compacted separated batch of material in said upper compartment to fall into said lower compartment through said internal passageway and then moving said second ram forwardly to push the compacted material in said lower compartment out of said material dispensing opening.
Claim 3
Dependent Claim
41 words
A batch ram feeding apparatus, as set forth in claim 1, further including a hopper means connected to the top of said housing and communicating with said material receiving opening for containing a bulk of material for feeding through said apparatus.
Claim 4
Dependent Claim
30 words
A ram feeding apparatus, as set forth in claim 1, in which said drive means includes a double-acting, fluid-operated piston and cylinder means connected to each of said ram means.
Claim 5
Dependent Claim
30 words
A ram feeding apparatus, as set forth in claim 3, in which said drive means further comprises sequentially operating electrical circuit means operatively connected with said piston and cylinder means.
Claim 6
Dependent Claim
97 words
A ram feeding apparatus, as set forth in claim 4, in which said drive means includes pressure sensing means operatively connected between said piston and cylinder means for said upper ram and said electrical circuit means for sensing abnormal pressure on said upper ram during its forward movement caused by an obstruction of material between said hopper and said upper compartment or by abnormally uncompressible material in said upper compartment and for actuating said electrical circuit means for causing rearward movement of said second ram to allow the batch of material to fall into the lower compartment.
Claim 7
Dependent Claim
22 words
A ram feeding apparatus, as set forth in claim 1, in which said compartments and said rams have generally rectangular cross-sectional configurations.
Claim 8
Dependent Claim
43 words
A ram feeding apparatus, as set forth in claim 6, in which said upper compartment includes an outwardly inclined front wall and outwardly inclined side walls to ensure falling of the separated batch of material from said upper compartment into said lower compartment.
