into traction engines 1t Is possible to
employ them for all the various tasks
of operating a stone crusher, hauling
the stone to the road and finally rolling
the new made road.
One of these road building autOmO-
biles will. when in use as traction en-
CINE, haul load Of at least fifteen
tons Of stone over an ordinary road.
On the other hand, when transformed
into stationary engine for perating
a stone crusher, 1t furnishes sufficient
power to crush any ordinary rock for
use as the foundation Of the highway.
In conjunction with this apparatus the
up to date road builders are using
lately devised and very ingenious
dump cart, with an attachment for
automatically spreading on the road
any required thickness Of stone
In this time saving method of road
building the stone is dumped from the
eruShcr into the car. hauled to any de-
sired point on the road by means Of
the roller traction engine and then
spread over the surface undergoing
Improvement much more evenly and
rapidly and also much more cheaply
than it could possibly be done by the
use Of men and teams. The distribut-
ing apparatus on the dump car can be
80 adjusted that the sheet of crushed
stone. sand or gravel spread upon tho
road will be of any desired thickness
from one to eight inches. Attached to
this odd mechanical worker is an e.
CINE tender with q device for use in
sprinkling during the rolling process.
Other new paraphernalia Of great
value in twentieth century road build
ing operations are the complete porta-
BILE rock crushing outfits. including not |
only movable rock crushers proper, but |
have folding elevators. which raise the |
crushed stone fifteen feet from the |
ground. although the apparatus Is less |
than ten feet in height when folded, |
and so carefully has the weight been
kept down in planning these portable
outfits that it Is now possible to OBJ
tain Il movable plant of this kind that
S capable of handling fully twenty
0ns of stone per hour. Finally in the
same category is the portable storage
lin Oh wheels, which, though large
enough to hold twelve tons of stone,
Weighs when empty but $500 pounds.
IN occasion one of these entire outfits,
consisting of stone crusher, elevator,
Green and bin. has been set up ready
or road building inside Of fifteen min
ties.
There have been introduced during
he past few years some very wonder
nj road machines which will plOw
nd grade at surprising angles and will

Put as the ordinary apparatus would
,i,h toe wheels on level Most re-
of all. however. is the mar
elOus dirt elevator which plOws up
ne earth and lifts the loosened ma
rial into wagons or conveys it to the
enter of the roadway. The dirt ele
ator consists principally of an ad-
istable frame, with two rollers around
hich are placed WIDE endless can
as belt. The upper end Of the frame
lay be adjusted to suit the wagons
hich are to be filled or to deliver the
rt to the best advantage in grading.
