The southern sentinel. (Winnfield, La.) 1883-1910, 1903-05-22

being that there are slight ridges along
the outside edges of the wearing sur
face, which tend to keep the wagon
wheels in. the track. The rails came
in 40-foot lengths and were riveted to-
gether by means of three splice plates,
one on the under side of the main web
OF the channel, having three rivets for
each rail. countersunk on the top sur
face. The other two plates connect
the flanges. each with two rivets to
hange. The rails are spaced So feet
apart, center to center, and every 1874
feet longitudinally they are tied to-
gether with A-inch rods, bolted
through the outside fianges. The
foundation for the rails is 12 inches
Of broken stone resting on the old paw
| ing blocks replaced by the rails. The
under surfaces of the rails were coated
with tar and the rails then bedded on
thin layer of fine gravel.
In addition to this roadway in MUIR
ray street, which will be subjected to
the heaviest kind of traffic, it is pro-
posed to lay another stretch of the
steel road on Seventh avenue, in the
neighborhood of One-hundred-and-
twentieth street. There the pavementis
m old macadam, and there will neces-
earily be notifications of the founda-
tion and the methods of construction
to suit the locality. A trial will also
be made on some dirt road, for the
advantages of the steel rail are con-
sidered to be as great for a country
road as for city streets.
At the present price of steel it is
stated that the rails can be furnished
for $4,000 per mile. The cost of con-
struction would, of course. vary with
local conditions, and as the work so
far done is experimental and work
men had to be taught how best to per-
form the various operations Of laying
the track, no reliable estimate has
been made as to the total cost of lay
ing this roadway.
A thorough series of traction tests
are to be carried on in connection with
the roadway in Murray street, and the
other places where the rails are laid.
A dynamometer will be used and the
tractive force necessary to draw
truck over the granite paving will be
compared with that necessary to draw
It along the steel roadway. In addition
to this test, records have been made
showing the amount and weight of
traffic on the street previous to the
improvement, and further observa-
lions will be taken from time to time
to see whether there is any increase
in the traffic passing up this street
Gen. Stone has made a very exhaus-
tive study of steel highways, and has
had several patents issued to him in
regard to constructive details. These
ne states are to be entirely free to the
city of New York to make use of.
should the experiments prove as sue
cessful as is hoped. In rolling rails for
further experiments it is proposed to
make use OF special roll having slight
projections on its surface, perhaps an |
inch square. The last time the rail |
goes through the rolls this win be put |
on and viii leave corresponding de-
pressions in the finished rail. The OBJ
Ject OF this it to reduce to q minimum
the danger from horses slipping, and |
y an important consideration. How
ever, It is claimed that the use of steel |
faals viii 80 reduce the amount of |
traetfve force required that under
Ordinary conditions there will not be
much danger rom that source. An
osaer proposed modification is to have
she bead along the outer edges Of the
sfead huted so as to prevent wheels
lrom skidding as they leave the track.
N some cases it might also be advan-
sseeous to have the flanges of the rail
aaFng outward from the web on both
