MACHINE FOR PRODUCING TRAFFIC LINES
IN CONCRETE

Application October 26, 1935, Serial No. 46,901
5 Claims. (Cl. 94-45)
This invention relates to improvements in ma
chine for and method of producing tra?ic lines
in concrete and particularly to the means and
method wherein said tra?ic lines are inlaid in
5i. the plastic concrete roadbed under construction.
The principal object of the present invention
is the production of a traffic marking strip in the
body of a highway construction while the con
crete is green and plastic, thus insuring proper
10- bonding between the road construction material
and the marking strip.
Another object of this invention is the method
of inlaying a strip of plastic material in the
green material of a roadway so that upon hard
15? ening, the strip becomes an‘integral part of the
roadway.
'
'
A further object of the invention is the pro—
vision of a machine that is adjustable to roads
of different surface contours and widths.
Many other objects will appear during the
course of the speci?cation, wherein reference will
be had to the drawings, in which:

Fig. 11 shows a cross sectional view of the sled,
with the runners engaging the opposite side walls
of the groove.
‘
Fig. 12 is a section through the rear portion
5 O of the sled in the operative position, with the
groove ?lled with a plastic cement ?ller.
Fig. 13 is a vView similar to that shown in
Fig. 12, with the sled moved out of engagement
55 therewith.
Fig. 14 shows the cross sectional view of the
marking strip in its complete form, and,
Fig. 15 is a fragmentary, sectional view of the
hollow axle.
Throughout the several views like reference 5
characters designate similar parts and the nu
meral 2|] indicates a carriage or bridge member,
mounted on wheels 22 and 24, which in turn
are adapted to rest on the rails or side forms
25 that serve to maintain the road material 28 10
within the limits of the roadbed.
Wheels 22 are provided with double ?anges 20
that serve to maintain them in operative position
on the rail; also wheels 24 are provided with
flanges 32. The body of carriage 20 consists of 15
a fabricated framework, having end members
34 and 33 secured together by means of cross
members 38.
Each set of wheels 22 and 24 are in axial align
ment and are mounted respectively on hollow 20
axle 4i] and squared axle 42. These axles are
rotatably mounted in bearings M carried by mem
bers, 36 and 34 and squared axle 42 is slidably
mounted in the squared socket 46 positioned in
25
hollow axle 46.
The following driving mechanism is provided
for moving the entire carriage lengthwise of the
roadway and consists of a sprocket wheel 48, rig
idly mounted on axle 132, a transverse shaft 59
mounted in bearings 52, which in turn are carried 30
by platform 51%. Rigidly mounted on shaft 50 is a
small ‘sprocket wheel 56 which is interconnected
with sprocket wheel 48 by sprocket chain 58.
The opposite end of shaft 50 carries a sprocket
wheel 56 through the intermediacy of chain 62. 35
Through the intermediacy of chain 62 sprocket
60 is in operative relation with sprocket 64.
Sprocket 64 is mounted on a shaft 66, rotatably
carried by bracket 68, which is adapted to be
rotated manually by means of crank arm “Hi, 40
having a hand hold 12. This driving mechanism
is so geared that great leverage is obtained for
driving the carriage in either direction.
The mechanism for laying the marking strip
of concrete consists of a sled member '54, hav- 45
ing a body portion 16 and downwardly extend
ing runners 78. The lower portion of the body
of the sled is of planar form and is adapted to
rest on the surface of the roadbed with the down
wardly extending runners l8 engaging the side 50
walls 8%} of the groove 82. A vertically extend
ing wall 84, spaced-apart from the opposite run
ners, together with an U-shaped cross member
86, serves to form a hopper 88 which opens
into groove 82 when the sled is in the opera- 55

tive position. The rear end of the sled is of a
continuous planar form in cross section, as shown
in Fig. 8, and serves to form and pack the ma
terial into groove 82 as the sled is moved for
wardly. Sled ‘I4 is interconnected with carriage
20 for universal adjustment, thereby permitting
it to be adjusted to the contour of the road
surface, regardless of vthe cross sectional form of
the surface of the road.

Mounted on cross bars 38 are transversely dis
posedjparaiiel tubes 99, on which are adjustably
mounted brackets 92. These brackets are pro-_
vided with openings 94 and serve as bearings for
vertically disposed adjusting rods 95 to prevent

Collars 98 are secured to rod 95 at
opposite sides of 92, thereby allowing rotary
is now deposited between runners ‘I8 into groove
82. It is then leveled and packed by surface I24
of sled ‘I4. As the sled moves forwardly away
from the deposited material, it appears as shown
in Fig. 13 with slight grooves at its opposite edges.
It has been found best to slightly trowel the
inserted strip and the adjacent road material
after the machine has completed its work. For
convenience of the, workmen in operating the de
vice, a platform H26, supported at its opposite 10
ends on members 35 and 34, is provided. This
platform may be moved transversely of the ma
chine to position it relative to the sled ‘I4. > Other
similar platforms might be added if needed.
The carriage might be drawn by road surfac 15
ing machine thus eliminating the necessity of an
operator, or it might be provided with a motor

driving device that could drive it at any desired

with the body of the sled. For propelling the
sled during the operation of the machine, stand
ards H2 extend upwardly from the body of the
35 sled in the path of travel
the end member 36,
which serves to propel the sled forwardly with
out exerting too much strain on the adjusting
parts. Furthermore, these standards H2 are
positioned just to the rear of the tube 90, thus
making it possible to move the sled backwardly
forcing 92 against standards H2.
It will be observed that the U-shaped cross
member 86 is slightly rounded as at H4 so as
to ride over the material and cause a proper
45 packing of they same.
When this marking device is used on a crowned
road which consists primarily of two planar road
surfaces angled relative to each other, it is ap
parent that by the operation of hand wheels H6
mounted on shafts 96 the sled 14 may be tilted
to either side to conform to the surface of the
strip into which the marking strip is being em
bedded.
The method of forming or constructing this
55 marking strip is best shown in Figs. 4, 9, DD, 11,
12, 13, 14 and 15. Referring to Fig. 4, it will be
noted that an insert strip or ?ller H8 is em
