MACHINE FOR MARKING OR PAINTING LINES.

Original application filed March 14, 1924, Serial No. 699,379. Divided and this application filed March 29,

- 1926. Serial No. 98,295.

This invention relates to a machine for marking or palnting lines on streets, play- I grounds, athletic grounds, and other surfaces requiring marking. I

The present application is a continuation in part of an application for marking a paratus or machine, Serial No. 683,226, filed December 28, 1923, and a division of an application for machine for marking lines or b zzmds, filed March 14, 1924, Serial No. 699,- 3 9. The marking or painting of safety lines on streets and the division lines on. playgrounds,athletic fields and lil surfaces, has ordinarily been a hand operation which is slow and expensive on account of the time and labor involved.

The invention contemplates the provision of a wheeled machine which is adapted to be propelled and guided by a single operator and which has a compressed air tank, a storage tank for the fluid which is to be used to mark the lines, a novel arrangement of brushes which are spaced apart, means for directing the marking fluid to the space between the brushes so that the latter may utilize the fluid to lay down on the pavement or surface a line of the desired width, a supplemental brush; for smoothing down the marking material, an improved mounting for the brushes whereby they may be adj listed in relation to each other and elevated or lowered, an improved means for controlling the supply of the marking fluid by the position of the brushes, and other features such .as a bumper located in advance of the marking brushes and adapted to prevent them\from being struck by any object, and a runner so arranged that it will elevate certain parts and permit the marking brushes to be advanced so that they can mark a line close to the curb, and other features incident to the invention are set forth more fullyhereinafter. j The principal features of my present improvemcnts are the brushes'which define the margins of the line or band which is marked onthe surface traversed by the machine, and the means for supplying to the space between said brushes the marking or painting material under air pressure, with or without the smoothing brush which smooths down the marking material formed into a line or band by the markin brushes. By preference, the smoothing iHllSh is employed because superior results are obtained when it is used, but in its broadest aspect the invention is'not limited to the inclusion of the smoothing brush.

In the accompanying drawings,

Figure 1 is a perspective view;

Figure 2 is a plan view;

Figure 3 is a detail side elevation, showing the arrangement of the brushes, bumper, spiral brush and runner;

Figure 4 is a detail view of the mounting for the marking brushes;

Figure 5 is a similar view of one of the brushes; and

Figure 6 is a fragmentary perspective of a part of the storage tank for the marking material.

The frame of the machine is shown at 1, said frame being provided with wheels 2 which are preferably rubber tired. The rear wheels are preferably swiveled so that the machine may be easily guided and turned.

The marking apparatus is located at the front of the frame 1 and is carried by a shaft 3 mounted in brackets 4 secured to the front cross piece of frame 1 and having holes 5 to receive shaft 3 so that the shaft may be located at any desired height, said shaft be-- ing mounted to turn in said holes 5 so that the brushes may be swung upwardly, out of contact with the pavement or other surface being marked, when desired.

The brackets 6 which carry the brushes are secured to shaft 3 by set screws 7 and are adjustable toward and away from each other on said shaft so that the brushes may be disposed in any desired spaced relationship. The brackets 6 have slots 8 to receive the fastenings by which the brushes 9 are secured. T

The brushes may be of the construction shown in Figure 5 and provided with slots 10 to receive the shanks of the bolts 11 which pass through the slots 8 and are secured by the wing nuts 12. The bolts 11 and wing nuts 12 enable the brushes to be adjusted forwardly or rearwardly and up wardly or downwardly as may be desired and this adaptability for "adjustment, in connection with the adjnstability of the brackets 6 toward and away from each other, en-

' secured at the desired point by set screw 14.

This brush is located slightly to the rear of the brushes 9 and to the rear of the marking material distributor or nozzle which wil be described hereinafter, so that said brush 13 will properly perform its smoothing function.

To counterbalance the brushes and other parts carried ,shaft 3 there is rovided an adjustable arm 16 on s aft 3 w ich carries an adjustable weight 17.

The nozzle or distributor 15 may be perforated, or, interchangeable perforated disks having holes of different sizes maybe provided according to the liquid marking material used and the consistency thereof. The distributor 15 is so located that it will discharge or flow the marking material between the brushes 9 and in front of the brush 13.

The distributor 15 is carried by a pipe 18 which has a valve 19 for controlling the flow therethrough., The valve 19- is connected by a chain, cord, or other suitable connection 20 to one of the brackets 6. A pull-rod 21 which is connected to the valve 19 and is mounted in a bearing 22 on the cross piece of the handle 23, may be utilized for the purpose of simultaneously opening valve 19 and lowering the brushes, or, closing valve 19 when raising said brushes. Thus, by one operation, the marking means and the flow of the marking material to the distributor 15 are jointly controlled. 1

Liquid marking material such as needed for marking a street, playground, etc., is liable to settle in the storage tank and its uniform consistency is not easily maintained. For that reason, the storage tank 24 for the liquid marking material is mounted so that it may be oscillated. A convenient mounting comprises trunnions 25 carried. by the tank 24 and supported on the standards 26 which are carried by frame 1.

The pipe 18 is connected to the tank 24 by a hose 27 which, in turn, is attached to the pipe fitting 28leading to the tank, a

strainer 29 being provided to strain all of the material flowing from the tank to the distributor 15. A valve 30 is provided for cutting off or opening communication between tank 24 and the distributor 15. The tank 24 has a closure 31 for the opening through which the marking material may be introduced.

The compressed air tank 32 which is carried by the frame 1 has a valve 33 for the connection of a pipe through which air pressure from any suitable source may be delivered to said tank. A pipe 34 and flexible hose 35, afford means for introducing compressed air into tank 24 from tank 32, A controlling and reducing valve 36, interposed in pipe 34 enables the proper, reduced, pressure to be had in tank 24. i valve 37 in pipe 28 provides means for opening or shutting'ofi communication between the two tanks.

A pressure gage 38 on tank 32 enables the operator to keep track of the pressure in that tank and a gage 39 in pipe 34 in dicates the pressure in the tank 24.

To guard the brushes 9 so that they will not be injured by striking any object, there is provided an arched bumper 40 of spring steel secured to frame 1.

I may provide a spiral, rotary brush 41 driven by a sprocket chain 42 from sprocket wheel 43 on one of the wheels 2. This brush is carried by a frame comprising arms 43 rockably mounted on the axle 44 of the front wheels 2, and a cross bar 45 con-- meeting said arms. The arms are supported at their forward ends by swiveled wheels 46. The shaft 47 of the brush 41 is adjustably mounted in the arms 43 by means of tension screws 48 engaged with the bearings 49 which slide in slots.

The frame for the brush is provided with a curved runner 50 which projects out in front of the brush 41 in position to engage the curb for the purpose of swinging the arms 43 and brush 41 upwardly so that the brushes 9 may mark the line close up the curb when such marking is desired.

In the claims, when the word brush or brushes appears as having relation to the marking means, it is to be understood that, unless otherwise specified, there is intended to be covered thereby any device or devices having a wiping, contacting, or brushing action in relation to the surface being marked, and possessing the function of defining the margins of the line or band being marked or ainted.
