Abstract

A line marking machine comprises a wheeled chassis (21) supporting a reservoir (22) for paint and a downwardly directed nozzle (23), a line (24) connecting said reservoir with said nozzle, and powered drive means (25) for supply of paint to said nozzle. The drive means suitably drives a compressor (26) with the compressed air flowing first through a chamber (29) before reaching the nozzle (23) in order to buffer the pressure of air entering the nozzle. <IMAGE>

Description

LINE MARKING MACHINE This invention concerns a line marking machine, particularly but by no means exclusively, for marking lines on grass or other sport surfaces, for example tennis courts and soccer pitches.
One known line marking machine comprises a transfer wheel mechanism. In this type of line marking machine paint is transfered from a reservoir, which is mounted on a chassis, to the grass or other surface by a series of wheels. The back wheels of the chassis are linked by a belt drive to a wheel which is immersed in the paint reservoir and connected to the front wheel of the chassis by an intermediate transfer wheel. The main problem with this type of machine is that the paint is not tranfered evenly onto the grass surface and the wheels may jam if they become clogged with dried paint.
To overcome these problems, a more recent type of line marking machine has been devised whereby the paint is pressurised and sprayed onto the grass surface though a downwardly directed nozzle. The paint is pressurised by hand pumping a supply vessel, however, a major problem with this type of machine is that the pressure in the vessel does not remain constant and continually requires pumping. As a consequence, the line of paint sprayed onto the surface varies in width and density according to the pressure in the vessel.
The present invention overcomes, at least to some extent, the problems aforesaid.
According to the present invention there is provided a line marking machine comprising a wheeled chassis supporting a reservoir for paint and a downwardly directed nozzle, a line connecting said reservoir with said nozzle, powered drive means for supply of paint to said nozzle.
The nozzle may be an atomising nozzle, said drive means driving a compressor for the supply of compressed air to the nozzle.
The drive means may be an internal combustion engine.
The flow of paint from the reservoir to the nozzle may be controlled by a valve in the connecting line.
There may be a chamber between the compressor and nozzle to act as a buffer for the compressed air before it is directed through the line into the nozzle.
There may be a trigger controlling a valve in the line connecting the compressor and nozzle to switch the flow of compressed air on or off.
The drive means may drive a pump for pumping paint to the nozzle.
The drive means may be a battery powered electric motor.
The reservoir of paint may be interchangeable with other reservoirs containing paint of different kinds or colours.
The height at which the nozzle is set may be adjustable to affect the desired line thickness.
The nozzle may be downwardly and forwardly directed to enable paint to be sprayed therefrom right up to an obstruction such as a wall or golf post for example.
The nozzle may be self cleaning.
The invention will be further apparent from the following description with reference to the several figures of the accompanying drawing, which show, by way of example only, two forms of the line marking machine, embodying same.
Of the drawing: Figure 1 shows a side elevation of the first form of machine; Figure 2 shows a diagrammatic representation of the machine of figure 1; and Figure 3 shows a side elevation-of the second form of machine.
Referring firstly to Figures 1 and 2 of the drawing, it will be seen that the line marking machine 20 comprises a wheeled chassis 21 supporting a reservoir for paint 22 and a downwardly directed atomising nozzle 23, a line 24 connecting the reservoir 22 with the nozzle 23, an engine 25 driving a compressor 26 and a line 27 for supply of compressed air to the nozzle 23.
The engine 25 is a petrol fuelled-engine and is operated in a known manner to power the compressor 26.
The flow of compressed air is controlled by a trigger 30 operating a valve 31 to switch the supply of air on or off.
The flow of paint from the reservoir 22 to the nozzle 23 is controlled by a valve 28 in the connecting line 24. The flow may be shut off to enable the removal of the reservoir 22 which is interchangable with other reservoirs containing paint of different kinds or colours.
Paint flows to the nozzle 23 when the valve 28 in line 24 is open. At the same time, compressed air is directed into line 27 when the trigger 30 is swiched to 'On'. Compressed air first flows through a chamber 29 before reaching the nozzle 23 to buffer the pressure of air entering the nozzle. Once compressed air is flowing through the nozzle 23 paint is drawn into the air stream and out through the nozzle 23 in a constant spray due to the "Bunsen" effect.
The nozzle 23 is directed forwardly as well as downwardly to enable a line to be sprayed right up to an obstruction such as a wall or goal post for example.
The nozzle 23 is self cleaning and so prevents the nozzle clogging and affecting the quality of the line marked.
Turning now to Figure 3, it will be seen that the second form of machine is generally similar to the first, like parts being indicated with like reference numerals. However the nozzle 23 is an ordinary fish-tail spray nozzle to which paint may be supplied by a pump 40 driven by an electric motor 41 powered by a rechargeable battery 42.
A valve 43 is provided in line 24 to control the rate of supply of paint to the nozzle 23, excess paint being returned to the reservoir 22 through line 44.
In both forms of machine the width of the line may be adjusted by varying the height or angle of inclination of the nozzle 23.
The density of the line is controlled by the rate of supply of paint.
It will be appreciated that it is not intended to limit the invention to the above example only, many variations, such as might readily occur to one skilled in the art, being possible, without departing from the scope thereof as defined by the appended claims.
