forms or rails between which the roadway is to be formed
as these rails constitute guides for the machinery which
for-ms the surface of the roadway. As indicated in the
objects of this invention the machine of the invention
can be pushed along the surface of side forms or over the
?nished surface of a roadway to test the proper vertical
elevation of the form or the roadway and to mark any
roadway or a roadway form which deviate from the de
sired level or grade.

What is claimed as new is:
l. A machine for detecting surface irregularities in
roadways and forms therefor comprising an elongated
relatively rigid body in the form of an I-beam, ground

handle on the rear of said body, a rotatable grip on said
shaft 37 rotatably mounted in a suitable bearing bracket
38 on the top of the I beam. The further end of the 10 handle connected to said front wheel to steer the front
wheel, an arm vertically swingably mounted on the un
indicator shaft 37 has an upwardly projecting pointer 39
derside of said body and having a ground engaging de

tector wheel mounted on a swinging portion thereof near
40 secured to the top of the I beam. The dial 40 is
the midpoint of said body, a dial on said body facing said
