Abstract
Abstract A briquetting press roll comprising a roll frame which retains a plurality of replaceable mold segments. The mold segments have a top working surface of a hard, highly wear-resistant material and a bottom surface opposite the top surface. Two opposite end walls connect the top working surface and the bottom surface, which end walls diverge with respect to each other from the bottom surface. Two opposite side walls also connect the top working surface and the bottom surface. The side walls include means for detachably connecting the mold segments to the briquetting roll frame and for restraining the segments from movement relative to the frame during briquetting operations.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
121 words
A mold segment for a briquetting roll, having A. a top working surface of a hard, highly wear-resistant material; B. an uninterrupted bottom surface opposite said top surface; C. two opposite end walls connecting said top working surface and said bottom surface, said end walls diverging with respect to each other from said bottom surface; and D. two opposite side walls connecting said top workinG surface and said bottom surface, said side walls having means for detachably connecting said segments to a briquetting roll frame and for restraining said segments from moving relative to said frame during briquetting operations including projections extending outwardly from said side walls and at least one concave portion in said side wall to receive retaining means.
Claim 2
Dependent Claim
121 words
A mold segment for a briquetting roll, having A. a top working surface of a hard, highly wear-resistant material; B. an uninterrupted bottom surface opposite said top surface; C. two opposite end walls connecting said top working surface and said bottom surface, said end walls diverging with respect to each other from said bottom surface; and D. two opposite side walls connecting said top workinG surface and said bottom surface, said side walls having means for detachably connecting said segments to a briquetting roll frame and for restraining said segments from moving relative to said frame during briquetting operations including projections extending outwardly from said side walls and at least one concave portion in said side wall to receive retaining means.
Claim 3
Dependent Claim
13 words
The mold segment of claim 1 in which said bottom surface is flat.
Claim 4
Dependent Claim
42 words
The mold segment of claim 1 in which said top working surface is the general shape of a segment of the annular surface of a cylinder and in which said bottom surface is concave, but not coaxial with said top working surface.
Claim 5
Dependent Claim
40 words
The mold segment of claim 1 in which said top working surface has the general shape of a segment of the annular surface of a cylinder and said end walls are transverse to the curved surface of the top surface.
Claim 6
Dependent Claim
20 words
The mold segment of claim 4 in which said end walls are normal to the curve of said top surface.
Claim 7
Dependent Claim
22 words
The mold segment of claim 1 in which said side walls are perpendicular to the top and bottom surfaces of said segment.
Claim 8
Dependent Claim
21 words
The mold segment of claim 1 in which said side walls diverge with respect to each other from said bottom surface.
Claim 9
Dependent Claim
57 words
The mold segment of claim 1 in which said means for detachably connecting said segments to the briquetting roll frame and for restraining said segments from moving relative to said frame during briquetting operations comprises portions of said side walls which are not in a common plane which plane is perpendicular to said top and bottom surfaces.
Claim 10
Dependent Claim
22 words
The mold segment of claim 1 in which said top working surface contains at least a portion of one mold cavity therein.
Claim 11
Dependent Claim
22 words
The mold segment of claim 9 in which said top working surface has one complete mold cavity and two half-mold cavities therein.
Claim 12
Dependent Claim
17 words
The mold segment of claim 1 in which said projections are in the shape of cylinder segments.
