pistons. The use of a bushed cover for the large piston
end, and a flat cover for the small piston end makes it
possible to apply the main valve without danger of
breaking the rings since all rings can be observed.
The diagrammatic views, Plates 1 and 2, represent
the new standard compressors but the slide valve revers­
ing valve is shown by small supplementary views, and
the section of this pamphlet under "Operation" applies
equally to both the old and the new standard com­
pressors.
lOY2" CROSS COMPOUND AIR COMPRESSOR
The use of compressed air in the industrial field
has been so widely extended that the 10%" cross com­
pound compressor was developed for this particular
service, where ordinarily, steam is not available at the
high pressure used in railway braking service, and the
air pressures used are not so high.
The' 10%" compressor operates on the relatively Imy
steam pressure of 100 pounds, with a normal displace­
ment of 150 cubic feet of air at 80 pounds pressure. The
air cylinders are not water jacketed and no intercooler is
required. In all essential details this compressor follows
the same general design as that of the 8%" compressor
previously described.
General data covering the principal dimen::;ions,
weight, etc., of the 10%" compressor is given on page 32.
General Instruetions for the installation and care of
10%" compressors in industrial service are eovered by
