Feb. 6, 1934. E. F. WOODS STRIPE PAINTING MACHINE Filed Feb. 9, 1951 W V ENTOR.

Patented F ch. 6, 1934 UNlT'ED STATES PATENT OFFICE Application February 9,

1 Claim.

This invention is for a stripe painting machine, and has special reference to a machine for painting delineating stripes on streets and courts, such as safety zones, trafiic indicators,

dead lines and center lines.

The main object of the invention is to provide a painting machine which is mounted on wheels and can be pushed along a definite course and which will paint a stripe of any desired width as it is moved along.

Another object of the invention is to provide a machine of the character described which will maintain a straight course, so as to produce straight lines.

Other objects and advantages of the invention will become apparent as the following description is read on the drawing forming a part of this specification.

The invention consists primarily of a four wheeled vehicle provided with a push handle, an adjustable brush holder for holding a paint brush in cooperative relation to a surface and means for moving the brush away from the surface, a covered paint tank mounted at the forward end of the vehicle, and means for governing the flow of paint from the tank, the brush following the fiow of paint and spreading it.

The invention is adequately illustrated in the accompanying drawing in which: Fig. 1 is a top plan view of the invention;

Fig. 2 is a side elevation thereof;

Fig. 3 is an enlarged detail of the brush holder;

Fig. 4 is an enlarged detail view partly in section of the paint feeding valve and nipple.

35 Similar reference characters are used to indicate identical parts throughout the several views.

The carriage consists of an angle iron frame 10 of rectangular construction and supported by four wheels 11 which are mounted in true alignment so as to follow a straight'course, none of the wheels being adapted to steering the carriage. They are preferably made exactly equal in size and fixedly mounted on through shafts 12 which are rotatably mounted in bearings 13 which are secured to the side members of the frame 10.

The handle 14 provided with a cross hand bar 15, is fixedly mounted on the carriage by means of a yoke 16 spanning the side members of frame 10 and a brace 17 cooperating between the handle 14 and the rear member of frame 10, the yoke being secured to the lower end of handle 14 by means of bolts or rivets as indicated at 18.

- The paint brush is indicated at 19 and is adjustably secured by clamps 20 which are affixed to or integral with a bracket member 21 which is fixedly mounted on a rod 22 which in turn is pivoted in the side members of frame 10 as indicated at 23. An adjusting rod 24 is pivot- 1931. Serial No. 514,487

ally secured to an arm 25 integral with bracket 21 and extending from one side thereof. Rod 24 has a handle 26 for convenience of adjustment of the brush holder and is adapted to swing the brush 19 to or away from the surface of the street or court.

The paint distributor consists of a storage tank 27 having a close fitting cover 28 and a conical bottom 29 and mounted on standards 30 which are secured to the side members of frame 10 as indicated at 31, ears 32 being integral with or affixed to the tank, for cooperation with the standards 30. The bottom of cone 29 terminates in a nipple end 33 which is threadedly secured in a valve 34. A nipple 35 is secured in the opposite end of valve 34 and has a cup 36 threadedly secured thereon, the cup having a central aperture 37 through which the fiow of paint is limited to the maximum amount coverable by the brush 19. The nipple is easily removed for cleaning.

A rod 38 provided with a handle 39 is adapted to adjustment of the valve 34 and is indicated as attached to the handwheel 40 by means of a link 41. A cross member 42 centrally supports the tank 27.

The operation of the device is as follows. The

tank 27 is partly filled with paint and the carriage moved central with the position of the desired stripe, with nozzle 36 over the point where the stripe is to begin. Valve 34 is then opened by turning the handle 39 and the carriage pushed forward. As the brush 19 reaches the beginning point of the stripe, handle 26 is drawn back, forcing the brush into contact with the surface, which then spreads and smooths the stream of paint fed through nozzle 36. As the nozzle reaches the point Where the stripe is to end, the flow of paint is shut off by means of the handle 39 and as the brush 19 reaches that point, handle 26 is pushed forward lifting the brush from the surface, and terminating the stripe.

It will be understood that variations in construction and arrangement of parts which are consistent with the appended claim may be resorted to without detracting from the spirit or scope of the invention or sacrificing any of the advantages thereof.

I claim:--

In a stripe painting machine, a carriage including a pair of special frame-bars, a horizontal rod pivotally mounted at its opposite ends in said bars, a vertically disposed bracket fixedly connected to said rod, clamps on said bracket to secure a paint-brush in adjusted relation to the surface to be painted, and an adjusting rod secured to the upper end of said bracket whereby the paint-brush may be rockedto assume various angular positions relative to said surface.

EDWARD F. WOODS.
