posing the arches being spliced together 80 as
irtually to form one continuous piece oil the
requisite hghtness and strength. These arches
support the track or roadway by means OF verti-
cal rods, twelve feet apart, and fastened by nuts
to cross pieces underneath, these being the only
rods or bolts used In the construction. The
bridges are in this way rendered sufficiently light
and strong for The purpose required, with a sur
plus OF strength which prevents the possibility OF
their giving way under any strain TO which they
may be subjected In the ordinary running OF cars.
1t Is adapted to single or double track, and may
be used Tor wide or narrow streets, In the mtdd o
or along the sides. IL has small weight OF ma
teria will interfere but little with ordinary street
street Will cause the least oton of light to
the lower parts OF buildings. rhe plan Is also
adapted TO railway bridges generally. Its cost Is
comparatively moderate, the estimate per mile
for double track being $3.50 900.
The owners OF the patent are prepared to take
contract for construction aud will beam imme-
dlately and push the work through with great
rapidly,
This plan Is an elevated railroad which runs
over the sidewalk on arches, and which is arched
over so that the adjoining buildings can be ex-
tended out over the railroad II desired, and
thereby the inventor claims much room is gained
and the value OF the property adjoining the rail-
road Is materially increased.
The sidewalk is to be exeavatad where such is
not the case, and the room thus gained Will be an
addition TO she adjoining property. In these ex-
cavatons are erected stone pillars which support
the columns, and which are connected by arches
through which light Will be admitted at the proper
intervals ana which form the support for the SIDE.
Inc Columns Will De from nlteon 10 eighteen
feet apart, one series OF columns being at the
outer edge OF the sidewalk and the other series
either in the walls OF the adjoining buildings or
close TO the same. These columns are constructed
each OF ave tubes, which may be maue OF cast iron
or any other suitable material, tne middle tube
being about one foot in diameter, while the
diameter OF the outer tubes VIII be about Blk
inches. With these tubular columns is combined
suitable iron bed plate provided with sockets
for the reception OF the several tubes, and each
OF said tubes may be cast in two more section
wnlch are united by suitable joints which are sc
made tnat they form ornaments for the columns
The capitals OF the columns are also made OF cast
iron and provided with suitable sockets TO it the
upper ends OF the several tubes. The pillars. which
are erected IN the walls OF the ajoinlng buildings,
are preferably made square ana butt up OF granite
and other stones.
The columns and pillars are united by arched
beams or orders, which Will be cast or otherwise
produced by Bessemer steel or spring steel, ana
ON the endS ofthese arched Orders rest the lOngi
tudinal beams, which extend parallel TO the faces
or the adjoining buildings aud form the connect
lions between the successive columns on the out
side and the successive pillars on the inside.
1hese longitudinal beams are intended TO be from
thirty TO thirty-sx feet in length, ana, wnen they
are put mp, they form continuous lines from one
terminus Of the road TO the Other. Between these
Longitudinal! beams are placed Eve additional
