Abstract
Abstract A shear and breaker structure for use with a briquet forming construction comprising opposed briquetting means adapted to produce a sheet consisting of at least two rows of briquets. The shear means operate to divide the sheet into strips with each strip consisting of at least one row of briquets. The shear means consist of opposed, stationary members, positioned in side-byside relationship with each having a bearing surface for engaging the sheet. The stationary members define an open mouth with the bearing surfaces tapering towards each other to form a throat or juncture. The tapering surfaces thereby divert the briquet strips in different directions upon separation of the sheet at the juncture of the stationary members. Knife edges are formed in the stationary members to facilitate the separation. The bearing surfaces define a pronounced outwardly extending portion beyond the juncture which serves to produce longitudinal stress in the briquet strips thereby creating fracture between the individual briquets to divide the strips into individual briquet portions.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
174 words
In a briquetting construction wherein material is fed between opposed briquet forming means and is thereby formed into a sheet comprising a plurality of rows of briquets and interconnecting web portions, the improvement comprising means for dividing the sheet of briquets into individual strips comprising at least one row of briquets, said dividing means comprising a plurality of bearing members having bearing surfaces extending on opposite sides of a plane defined by the path of movement of the sheet, said bearing surfaces being laterally spaced whereby each is aligned with a row of briquets, and said bearing surfaces tapering inwardly towards each other and passing through said plane whereby junctures are formed between the bearing members, the movement of said sheet into engagement with said bearing members at said junctures operating to shear the sheet into individual strips, and wherein said bearing surfaces bend outwardly beyond said junctures whereby each strip is forced against the outwardly extending portions to create a bending action in the strips whereby the strips are separated into individual briquets.
Claim 2
Dependent Claim
174 words
In a briquetting construction wherein material is fed between opposed briquet forming means and is thereby formed into a sheet comprising a plurality of rows of briquets and interconnecting web portions, the improvement comprising means for dividing the sheet of briquets into individual strips comprising at least one row of briquets, said dividing means comprising a plurality of bearing members having bearing surfaces extending on opposite sides of a plane defined by the path of movement of the sheet, said bearing surfaces being laterally spaced whereby each is aligned with a row of briquets, and said bearing surfaces tapering inwardly towards each other and passing through said plane whereby junctures are formed between the bearing members, the movement of said sheet into engagement with said bearing members at said junctures operating to shear the sheet into individual strips, and wherein said bearing surfaces bend outwardly beyond said junctures whereby each strip is forced against the outwardly extending portions to create a bending action in the strips whereby the strips are separated into individual briquets.
Claim 3
Dependent Claim
35 words
A construction in accordance with claim 1 wherein said bearing members define an open mouth portion substantially greater than the width of said sheet to thereby insure entry of the sheet between the bearing members.
Claim 4
Dependent Claim
23 words
A construction in accordance with claim 2 including knife edges formed in said bearing members at least in the area of said junctures.
Claim 5
Dependent Claim
59 words
A construction in accordance with claim 2 wherein said briquet forming means comprise briquetting rolls having means for feeding material to the niP of the rolls, and wherein the upper edges of said bearing members are located immediately adjacent the periphery of said briquetting rolls to thereby minimize the distance between the nip of the rolls and said junctures.
Claim 6
Dependent Claim
45 words
A construction in accordance with claim 4 including a transversely extending support for said bearing members, said support operating to hold said bearing members in position in opposition to the longitudinal forces developed in said sheet between the nip of said rolls and said junctures.
Claim 7
Dependent Claim
45 words
A construction in accordance with claim 5 including means for circulating a cooling medium in said support to thereby maintain the support and the bearing members associated therewith at a lower temperature relative to the temperature of the sheet being delivered to the bearing members.
Claim 8
Dependent Claim
94 words
A construction in accordance with claim 4 wherein said briquetting rolls each define pockets and flat areas, the flat areas of one roll being located in opposing relationship relative to the pockets of the other roll when the flat areas and pockets are at the nip of the rolls, and wherein said bearing members are positioned to engage the flat side of the sheet formed by the briquetting rolls, with the sheet portions formed by the pockets of the rolls moving in the spaces defined between bearing members opposite the members engaging the sheet.
Claim 9
Dependent Claim
36 words
A construction in accordance with Claim 7 wherein said sheet includes web portions extending longitudinally of the sheet between rows of briquets and wherein the longitudinal web portions of the sheet are aligned with said junctures.
Claim 10
Dependent Claim
34 words
A construction in accordance with Claim 8 including transversely extending web portions defined between individual briquets, and wherein said strips bend about said transverse web portions so that the strips separate in these areas.
