Abstract
Abstract A briquetting construction of the type employing opposed rolls or other means for forming a length of compacted material. Means are provided for breaking the length of material into separate pieces comprising a shoe having a surface portion located in the path of movement of the length of material. Engagement of the length of material with the surface portion operates to deflect the length of material out of the path of movement with longitudinal stress being developed whereby cracks are formed in the length of material. The material is driven into engagement with a separate surface, preferably the moving surface of one of the briquetting rolls, to achieve fracture.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
144 words
In briquetting and compacting constructions wherein material is fed between opposed forming means and is thereby formed into a continuous, moving, length of compacted material issuing from said forming means, the improvement comprising means for breaking the compacted material into separate pieces, said breaking means comprising a shoe positioned beyond the briquet forming means, a surface portion of said shoe located in the path of movement of said length of material, engagement of said length with said surface portion operating to deflect said length out of said path of movement, and whereby longitudinal stress is developed in said length between said forming means and said surface portion, and including moving engaging means located in the path of movement of said length after deflection by said surface portion, said moving engaging means imparting a further deflection to said length thereby breaking said length into pieces.
Claim 2
Dependent Claim
144 words
In briquetting and compacting constructions wherein material is fed between opposed forming means and is thereby formed into a continuous, moving, length of compacted material issuing from said forming means, the improvement comprising means for breaking the compacted material into separate pieces, said breaking means comprising a shoe positioned beyond the briquet forming means, a surface portion of said shoe located in the path of movement of said length of material, engagement of said length with said surface portion operating to deflect said length out of said path of movement, and whereby longitudinal stress is developed in said length between said forming means and said surface portion, and including moving engaging means located in the path of movement of said length after deflection by said surface portion, said moving engaging means imparting a further deflection to said length thereby breaking said length into pieces.
Claim 3
Dependent Claim
144 words
In briquetting and compacting constructions wherein material is fed between opposed forming means and is thereby formed into a continuous, moving, length of compacted material issuing from said forming means, the improvement comprising means for breaking the compacted material into separate pieces, said breaking means comprising a shoe positioned beyond the briquet forming means, a surface portion of said shoe located in the path of movement of said length of material, engagement of said length with said surface portion operating to deflect said length out of said path of movement, and whereby longitudinal stress is developed in said length between said forming means and said surface portion, and including moving engaging means located in the path of movement of said length after deflection by said surface portion, said moving engaging means imparting a further deflection to said length thereby breaking said length into pieces.
Claim 4
Dependent Claim
144 words
In briquetting and compacting constructions wherein material is fed between opposed forming means and is thereby formed into a continuous, moving, length of compacted material issuing from said forming means, the improvement comprising means for breaking the compacted material into separate pieces, said breaking means comprising a shoe positioned beyond the briquet forming means, a surface portion of said shoe located in the path of movement of said length of material, engagement of said length with said surface portion operating to deflect said length out of said path of movement, and whereby longitudinal stress is developed in said length between said forming means and said surface portion, and including moving engaging means located in the path of movement of said length after deflection by said surface portion, said moving engaging means imparting a further deflection to said length thereby breaking said length into pieces.
Claim 5
Dependent Claim
56 words
A construction in accordance with claim 1 wherein said forming means comprise opposed briquetting rolls, the axes of said rolls being movable horizontally relative to each other, said shoe being secured to one of said rolls whereby the relative position of said shoe and the other roll will change upon relative horizontal movement of the rolls.
Claim 6
Dependent Claim
48 words
A construction in accordance with claim 2 wherein a second shoe is associated with the other roll, said second shoe having a surface portion opposite said surface portion of said first mentioned shoe with a guide channel for said length of material being defined between said surface portions.
Claim 7
Dependent Claim
44 words
A construction in accordance With claim 2 wherein said shoe includes an upwardly extending portion defining an upper edge positioned immediately adjacent said one roll, said edge serving as a stripper means to insure separation of said length of material from said one roll.
Claim 8
Dependent Claim
25 words
A construction in accordance with claim 4 wherein said second shoe defines a corresponding upper edge to provide a stripper means for said other roll.
Claim 9
Dependent Claim
57 words
A construction in accordance with claim 1 wherein said forming means comprise a pair of briquet forming means comprising a pair of briquetting rolls, and wherein said moving engaging means for said length of material comprise one of said rolls, said surface portion of said shoe deflecting said length of material into engagement with said one roll.
Claim 10
Dependent Claim
94 words
A construction in accordance with claim 6 including a second shoe positioned opposite said first shoe with a surface portion of said second shoe combining with said surface portion of said first shoe to provide a guide channel for said length of material, said guide channel deflecting said length of material from a path of movement in a plane extending vertically downwardly through the nip of said rolls to a path of movement between 50* and 90* relative to said plane whereby said length of material is driven into contact with said other roll.
Claim 11
Dependent Claim
32 words
A construction in accordance with claim 7, wherein said rolls are movable horizontally relative to each other, said first and second shoes being mounted on said rolls for movement with said rolls.
Claim 12
Dependent Claim
59 words
A construction in accordance with claim 8 including transversely extending brace means for supporting said first and second shoes, said brace means operating to resist the downward longitudinal forces which are transmitted through said length of material by said rolls, said brace means thereby maintaining said shoes in position for the deflection and breaking of said length of material.
Claim 13
Dependent Claim
19 words
A construction in accordance with claim 3 wherein conduits are defined by said shoes for the passage of coolant.
Claim 14
Dependent Claim
42 words
A construction in accordance with claim 3 wherein conduits are defined by said shoes for the passage of lubricant, and including said passages extending from said conduits to the opposed surface portions of said shoes for feeding lubricant to said surface portions.
Claim 15
Dependent Claim
93 words
A construction in accordance with claim 3 including transversely extending brace means for supporting said first and second shoes, said brace means operating to resist the downward longitudinal forces which are transmitted through said length of material by said rolls, said brace means thereby maintaining said shoes in position for the deflection and braking of said length of material, means connecting said brace means to said rolls for thereby securing the shoes to the rolls, said connecting means permitting relative movement between said brace means and said rolls during operation of the construction.
