ulated to another position to permit the wedge
I6 to descend to close the opening I5 as shown
in Figure 5 so that the material will not waste
while the machine is being transported from
place to place. The material will be delivered
from the tank 8 through the pipes 1 and 9 into
the chamber I4 under pressure su?icient to cause
the material to feed out onto the roadway
through the opening I5 but the excess material
10 will be returned into the tank through the re
turn line I2.
There is a suitable air compressor 2I mounted
on the vehicle 2Ia which also supports the tank
8. This compressor may be driven in any ap
15 proved manner and leading from it there is a
pressure line 22 which is formed into a coil in
the tank 8 and which emerges from said tank
adjacent the lines 1 and I2 and is coiled around
said lines as well as around the line 9 as more
20 accurately shown in Figures 1 and 2. This pres
sure line divides formingthe branches 23, 24, the
former of which enters the front nozzle cham
ber 25 in the nozzle and the latter of which en
ters the rear nozzle chamber 26 of the nozzle.
25 The forward chamber 25 terminates in a for
wardly directed nozzle opening 21 extending the
full width of the nozzle and the chamber 25 has
an outlet port 28. In mounting, the nozzle II
is arranged in angular relation to the paving 29
30 so that the nozzle opening 21 will be directed
forwardly and arranged in front of the opening
I5 to the end that a blast of air will be ejected
across the area to be marked so as to clean said
area of all loose material thereon before the
marking material is applied.
It is to be noted that the tank 8 is equipped
with the lower tubes 30 which lead from the rear
end thereof forwardly into the chamber 3| which
is separated from the main tank by the vertical
partition 32. Suitable burners as 33 are pro
vided in the rear ends of the tubes 30 which pro
ject a ?ame through said tubes to heat the same
and to heat the asphalt or other marking ma
terial with which‘ the tubes are surrounded in
the tank 8. The heated air returns through an
upper series of tubes 34 leading from the cham
ber 3I and terminating in the chamber 35 at the
rear of the tank from which the outlet or smoke
stack‘ 36 leads.
The asphalt will therefore be
50 delivered into the chamber I 4 in a heated state
and the air passing through the coil 22 will also
be heated and since this pipe 22 coils around the
pipes ‘I, 9 and I2 the material passing through
these pipes will be maintained in a heated state.
The hot air in the chambers 25, 26 will also main
tain the nozzle I I hot to the end that the asphalt
in the chamber I4 will not become too cold and
clog the nozzle outlet opening I5.
In operation the vehicle 2Ia will be moved
60 along the paving to be marked and may be guided
in the usual way. The nozzle carriage is suit
ably anchored to the vehicle and the nozzle II
will be positioned so as to move along the line to
be marked. The asphalt will be delivered through
65 the opening I5 directly on to the paving, leaving
a coating of the required thickness along said
line, the area to be marked having been pre
viously cleaned by a brush of conventional con
struction which may be mounted on the carriage
70 and by the air blast ejected through the nozzle
opening 21.
Special attention is called to the means for
varying the width and thickness of the ?lm of
marking material delivered onto the paving. It
75 will be noted that the nozzle I I is made up of
two sections I la and I Ib as clearly shown in Fig
These sections are secured to
gether in any preferred manner, preferably by
means of bolts 31 with a shim 38 clamped be
tween the margins of the sections as shown in
Figures 5 and 6. The outlet opening I5 is pro
vided by merely omitting the shim from the out
let end of the nozzle. Accordingly the trans
verse diameter of the nozzle opening I5 may be
varied as desired by varying the thickness of the 10
shim and the thickness of the ?lm of marking
material delivered will be correspondingly varied.
The length of the nozzle opening I5 may also be
ures 4, 5 and 6.
varied by varying the projecting ends of the shim
across the outlet end of the nozzle, that is, the 15
ends of the shim may be extended any desired
distance toward each other, as shown in Figure
4, to vary the length of said outlet opening I5.
As shown in Figure 4 the ends 3811 of the shim
are extended only a short distance inwardly to
ward each other but said ends may be extended
inwardly toward each other any desired distance
thereby varying the length of the opening I5 and
the width of the ?lm delivered onto the paving
will be correspondingly varied.
to Cl
Although asphalt will ordinarily be used, the
nozzle is capable of handling other suitable
marking materials in liquid state.
The drawings and description disclose what is
now considered to be a preferred form of the 30
invention by way of illustration only, while the
broad principle of the invention will be defined
by the appended claims.
What I claim is:
1. In a device of the character described a -
nozzle having a chamber for containing liquid,
said chamber terminating in a slot forming a dis
charge opening, said nozzle also having an air
chamber terminating in a nozzle opening diverg
ing from the discharge opening, and means for 40
supplying liquid and pressure ?uid respectively
to said respective chambers.
2. A device of the character described com
prising a container for liquid marking material,
a nozzle having an internal chamber terminating
in a transverse discharge slot, means for deliver
ing the liquid material from the container into
the chamber under pressure, a Wedge Within the
chamber movable into one position to completely
close said slot and into another position to open
the slot and a return line leading from the '
chamber above the discharge slot, and terminat
ing in the container.
3. A device of the character described com
