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 side walls connect the top working surface and the bottom surface, which side walls diverge with respect to each other from the bottom surface. Two opposite end walls also connect the top working surface and the bottom surface. The end walls include means for detachably connecting the mold segments to the briquetting roll frame and for restraining the segments for movement relative to the frame during briquetting operations.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
148 words
A briquetting press roll comprising the combination of: A. a roll frame comprising a cylindrical core having a pair of integral flanges extending around the periphery of said cylindrical core; and B. a plurality of mold inserts around the circumference of said core between said integral flanges, each of said mold inserts comprising: 1. a top working surface of a hard, highly wear-resistant material; 2. a bottom surface opposite said top surface; 3. 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 4. two opposite side walls connecting said top working surface and said bottom surface, said side walls having means cooperating with said integral flanges of said cylindrical core for detachably connecting said segments and for restraining said segments from moving relative to said roll frame during briquetting operations.
Claim 2
Dependent Claim
148 words
A briquetting press roll comprising the combination of: A. a roll frame comprising a cylindrical core having a pair of integral flanges extending around the periphery of said cylindrical core; and B. a plurality of mold inserts around the circumference of said core between said integral flanges, each of said mold inserts comprising: 1. a top working surface of a hard, highly wear-resistant material; 2. a bottom surface opposite said top surface; 3. 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 4. two opposite side walls connecting said top working surface and said bottom surface, said side walls having means cooperating with said integral flanges of said cylindrical core for detachably connecting said segments and for restraining said segments from moving relative to said roll frame during briquetting operations.
Claim 3
Dependent Claim
7 words
a bottom surface opposite said top surface;
Claim 4
Dependent Claim
7 words
a bottom surface opposite said top surface;
Claim 5
Dependent Claim
58 words
The briquetting press roll of claim 1 in which said roll frame comprises a plurality of surfaces around the circumference of said cylindrical core between said integral flanges, each of which surfaces is not of a uniform radial distance from the axis of said core, said surfaces being in contact with the bottom surfaces of said mold inserts.
Claim 6
Dependent Claim
30 words
The briquetting press roll of claim 2 in which said surfaces around the circumference of the cylindrical core are flat and form a polygon about the circumference of said core.
Claim 7
Dependent Claim
27 words
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
Claim 8
Dependent Claim
27 words
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
Claim 9
Dependent Claim
47 words
two opposite side walls connecting said top working surface and said bottom surface, said side walls having means cooperating with said integral flanges of said cylindrical core for detachably connecting said segments and for restraining said segments from moving relative to said roll frame during briquetting operations.
Claim 10
Dependent Claim
47 words
two opposite side walls connecting said top working surface and said bottom surface, said side walls having means cooperating with said integral flanges of said cylindrical core for detachably connecting said segments and for restraining said segments from moving relative to said roll frame during briquetting operations.
Claim 11
Dependent Claim
20 words
The briquetting press roll of claim 2 in which said surfaces around the circumference of the cylindrical core are convex.
Claim 12
Dependent Claim
64 words
The briquetting press roll of claim 1 in which said integral flanges have a plurality of indentations in their interior surfaces and said means for detachably connecting said segments and for restraining said segments from moving relative to said roll frame during briquetting operations comprise projections extending outwardly from said side walls of said segments, which projections mate with said indentations in said flanges.
Claim 13
Dependent Claim
18 words
The briquetting press roll of claim 5 in which said projections are in the shape of cylinder segments.
Claim 14
Dependent Claim
28 words
The briquetting press roll of claim 5 in which said projections extending outwardly from said side walls are perpendicular to the top and bottom surfaces of said segment.
Claim 15
Dependent Claim
66 words
The briquetting press roll of claim 1 in which said integral flanges have a plurality of projections extending outwardly from their interior surfaces and said means for detachably connecting said segments and for restraining said segments from moving relative to said roll frame during briquetting operations comprises concave portions on said side walls of said segment, which concave portions mate with said projections on said flanges.
Claim 16
Dependent Claim
26 words
The briquetting press roll of claim 1 in which said top working surface of each segment has one complete mold cavity and two half-mold cavities therein.
Claim 17
Dependent Claim
19 words
The briquetting press roll of claim 1 in which said end walls of adjacent segments abut against each other.
Claim 18
Dependent Claim
47 words
The briquetting press roll of claim 10 in which said top working surface of each of said segments has the general shape of a segment of the annular surface of a cylinder and in which said end walls are normal to the curve of said top surface.
Claim 19
Dependent Claim
20 words
