My invention is especially concerned with a device for
furnishing highway markers such as lane bottons or de 10 marily a brush 16, conveniently a rotatable brush having
lineators on the surface of a highway to show margins
or boundaries or other speci?c localities.
At present it is customary to afford a large number
of indicating marks on highway surfaces usually by pro
viding a paint stripe or the like.
In some instances,
particularly in towns, it is customary to mark the bound
aries of pedestrain lanes or vehicular tra?ic lanes by
means of prefabricated discs or plates which are put
on or in the material of the pavement and are held in
place either by fastenings such as lag bolts or by ad
an axle 17 from which a number of radial bristles pro
ject. The axle 17 is mounted in swing arms 18 connected
by a pivot means 19 to the frame 7. A chain 21 inter
connects the axle 17 of the bristle brush with a driving
motor 22 mounted on the ‘frame.
When the arms are swung downwardly, as shown in
FIGURE 1, the bristles of the brush 16 contact the sur
face of the pavement and when the motor 22 is energized,
the bristles revolve, thereby cleaning the surface and
It is therefore an object of the invention to provide a
even abrading some super?cial portions thereof, if neces
sary, to afford a clean, receptive area for a marker. When
the arms 18 are swung upwardly from the position shown
in the ?gure, the brush 16 is lifted from the surface and
is no longer effective thereon. Preferably, the arms
25 18 are raised and lowered periodically during the ad

There are some advantages but a
