TRAFFIC STRIPE MACHINE Filed April 10, 1935 3 Sheets-Sheet 5 INVENTOR ATTORNEY Patented Jan. 7, 1936 UNITED STATES ATENT OFFEE 2 Claims.

This invention relates to a machine especially adapted for placing markings or stripes on road or street surfaces to indicate traffic lanes or other trailic regulations and has for the primary object the provision of a. device of this character which will during its movement over a road or street clean a selected area of the surface of said road and apply thereto bituminous material and an aggregate, sand stone, gravel or slag, and roll or compress said materials to form the desired marking which may be seen for a considerable distance both day and night and is durable and not easily defaced, marred or worn off by traflic.

With these and other objects in view, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and. claimed.

For a complete understanding of my invention, reference is to be had to the following description'and accompanying drawings, in which Figure l is a side elevation illustrating a ma chine constructed in accordance with my invention.

Figure 2 is a top plan view illustrating the same.

Figure 3 is a front elevation illustrating the device.

Figure 4 is a rear elevation illustrating the device.

This machine is to be propelled or moved over a road surface in any well known manner and consists of a main frame I mounted on front and rear wheels 2 and 3. The axle of the front wheels 2 is indicated by the character 4 and is of the steering type actuated through the manipulation of a hand lever 5. The rear axle assembly for the rear wheels 3 is indicated by the character 6 and includes the usual differential which in this case is connected to a shaft 1 extending forwardly from the differential and geared to a power shaft 8. The power shaft is suitably journaled to the main frame I and arranged transversely thereof. The power shaft 8 is employed for driving various devices mounted upon the main frame by the forward motion of the machine over the road.

Mounted upon the forward portion of the main frame I is a tank or kettle 9 to receive bituminous or other similar materials-and the latter is kept at a desired temperature by heat derived from a suitable burner I0 supplied with liquid fuel from a supply source II mounted on the frame I. A pump I2 of any desired construction is mounted in the tank or kettle 9 and its intake has a pipe I3 which extends into the bituminous or like material in the tank or kettle while the outlet of the pump is equipped with a pipe I4 extending downwardly and rearwardly with respect to the tank or kettle and carries at its lower end a nozzle 5,

- 55 located in close proximity to the road surface.

The pump is driven by drive shaft 8 by a sprocket chain I6 and sprocket gears I'I.

Rotatably supported by the frame I forwardly of the nozzle I is a brush or broom I8 normally l0 contacting the road surface and which may be raised from the road surface by a hand lever 30. The brush or broom is rotated by the drive shaft 8, the latter being connected to the brush or broom by a sprocket chain I9 and sprocket gears 20.

A comparatively large container 2| is mounted upon the rear portion of the frame I in which sand, stone, gravel, slag or like material may be placed. The container 2| is in communication with the worm type conveyor 22 having the discharge end 23 located rearwardly of and in alignment with the nozzle I5. The conveyor is connected to the drive shaft 8 by a sprocket chain 24 and sprocket gears 25. 7

An operators seat 26 is carried by the container 2| and is located adjacent the steering lever 5. Secured to the frame I rearwardly of the conveyor 23 is a spreader 2'! spaced a desired distance from the surface of the road.

In operation, the machine is moved forwardly over a road in any desired manner and an area of the surface of the road or street has loose materials removed therefrom by the brush or broom I8. The bituminous material is discharged 85 by the nozzle I 5 rearwardly of the brush or broom to form a stripe or marking of a desired width. The aggregate or mineral material in the container 2| is discharged onto the bituminous material on the road by the worm conveyor 23. The aggregate or mineral material is evened by the spreader 21. One of the rear wheels 3 is disposed in alignment with the spreader 2'! and is in the form of a roller for the purpose of rolling the aggregate or mineral material into the bituminous material. Thus it will be seen that a very efficient marking is provided on the surface of the roadway easily and quickly with a minimum employment of manual labor and is capable of withstanding severe wear from traffic and may be seen or observed from a considerable distance both day and night.

A water supply tank 28 is carried by the con- 'tainer 2i and has a discharge nozzle 29 disposed over the roller type rear wheel of the machine A;

for the purpose of keeping said wheel moistened to prevent the materials deposited on the surface of the road or street from adhering thereto. The water may be controlled through the nozzle in any desired manner.

Having described the invention, I claim:

1. A machine comprising a portable frame, a tank or kettle mounted on the frame for containing and heating bituminous material, a rotatable brush or broom carried by the main frame to engage the surface of the road to clean an area of the surface of said road, a pump connected in the tank or kettle to obtain bituminous material therefrom, a discharge nozzle connected to the pump and arranged rearwardly of the brushand in close proximity to the surface of the road to apply the bituminous material in strip formation to the surface of the road, means carried by the frame to apply to the surface of the road within the bituminous material an aggregate or mineral material, and a spreader carried by the main frame to even the aggregate or mineral material deposited on the surface of the road, a roller carried by the main frame and acting as a wheel therefor and to compress the materials deposited on the surface of the road.

2. A machine comprising a portable frame, a tank or kettle mounted on the frame for containing and heating bituminous material, a rotatable brush or broom carried by the main frame to engage the surface of the road to clean an 5 area of the surface of said road, a pump connected in the tank or kettle to obtain bituminous material therefrom, a discharge nozzle connected to the pump and arranged rearwardly of the brush or broom and in close proximity to the surface of the road to apply the bituminous material in strip formation to the surface of the road, means carried by the frame to apply to the surface of the road within the bituminous material an aggregate or mineral material, a spreader carried by the main frame to even the aggregate or mineral material deposited on the surface of the road, a roller carried by the main frame and acting as a wheel therefor and to compress the materials deposited on the surface of the road, and means for applying water to the periphery of the roller to prevent the materials on the surface of the road from adhering to the roller.
