BRUSH .Foa Roan-MARKING MACHINES. v f

Application filed March 16, v1928. ySerial No. 262,144.

Broadly my invention has reference yto a machine for painting lines of demarcation on road'beds to indicate to traffic passing in oppositev directions. that they arek to keep within the side of the road bed and the warning line, and consequently prevent collision between such vehicleswhich otherwise is very liable to occur.

Specifically the improvement is ldirected to a brush head or paint applicator to be used in connection with a truck provided with a tank for containing a marking fluid or paint and anothertank for forcing such marking fluid under pressure intothe brush or applicator, as for vinstance such road markingmachine as forms the subject matter of my copending application Serial No. 164,036, filed by me January 27, 1927.

A further object is the provision ofv 4a 2O line in the center of a roadbed that is provided with a pointer guide for accurately directing the same, guard brushes at the sides thereof, a painting or spreading brush at the rear or between the guard brushes, an

intermediate brush arranged atan inclination and directed toward the rear brush, a

paint cup or receptacle that delivers the marking fluid onto the directing brush, .together with means forl pivotallyi supporting the brush head on a support at one side lof the wheeled tank carrying truck and means for adjusting the brush angularly with respect to the road bed. The invention will be fully and comprehensively understood from a consideration of the followingy detailed description when vread in connection with the accompanying drawings which form part of the application, with the understanding, however, that the improvement is capable of'extended-ap-.

plication and is not confined to the exact Y Vshowing of the drawings nor to the precise construction described, and, therefore, such;

-changes and modifications may be made therefrom as do not affect the spirit of the*` invention nor exceed the' scope thereof as expressed in the appended claims.

In the drawings: Figure 1 is a top provement.

Preferably thefbody of my' improvement is constructed of metal but obviously other suitable material can be employed. l .The brush head is indicated in the drawings by the numeral 1, thesame being of a substantially rectangular formation, having at its upper face and its outer edge a central longitudinally arranged notch or depression 2 and a rectangular opening 3 in a line with 'lower edges of the shields being cut atan inclination, and the top edges thereof being flanged and bolted,.riveted or otherwise securedto the under face of .the brush head 1.

The rear brush is indicated by the numeral -6 and the bristles thereof are secured to the brush head, the said brush head, on the inner face thereof,fhaving secured thereto innerv and Aouterangle plates whose depending flanges 7,v contact withl the inner and outer faces vat the top portion of the spreading brush 6.

. Secured on the top of the plate constituting the brush head through the medium of rremovable Vmeans 8 thereare the solid ends v9 of a paint or marking Huid recelving cup 10. The cupis ofy a width greater than the Vthe side walls formed by the depression 2. f

opening 3 #in the brush head and the outer face ofthe said cup,in a line with the said openingis notched yor cut-away, as at 11, and the notched or cut-away portion of the receptacleprovides theoutlet mouth thereof. Y Integrally formed on the ktop and Vat the centerof the receptacle 10 there lis a tubular extension 12 having a threaded end portion 13 to which is connected the hose leading from the fluid tank of thefmacliine to one side of which the vimprovement is attached.

Extending rearwardly from the flat and closed bot-tom of the receptacle 10, and bolted theretmas at 14, there is a plate 15. This plate is arranged below and in the path of contact with a laterally extending plate 16, and connecting the plates 15 and 16 there is adjustable means 17. The means may comprise a bolt passing through the plates and engaged by a nut, as disclosed b the drawings or a wing nut that passes reely through the plate 16 and is threaded through the plate 15. Y

The plate 16 has an angleend which is bolted to one of the arms 18 of the support for the brush head or applicator. Both arms of the support are provided with openings adjacent to their ends, and the walls of these openings afford bearings for short shafts or trunnions 19 that extend from the closed ends 9 of the receptacle 10. The arms 18 have their rearportions connected by a shaft (not shown)` upon which the wheels for the truck (also not shown) are journaled.

One or both of the arms 18 of the support have attached thereto an eye member 2O engaged by a rod which leads to the handle of the truck, and whereby the brush may be raised orlowered and likewise whereby the 4brush may be forced against the road bed with desired friction.

Seated in the depressed portion 2 of the plate or brush head 1 there is the notched and straight end 21 of an angularly disposed plate 22 which is received through the opening 3. Secured to the end of this plate 22'there is a directing brush 23. This brush is normally disposed in contacting engagement with the paint spreading brush 6. The

plate 22 is secured on the brush head by removable means, suchA as a bolt 24 which is engaged by a wing nut 25 and the bolt 24: passes through an opening, in the downwardly directed or i angularly disposed pointer guide 26. The pointerguide 26 is contacted by the wing nut 25- and thereby arranged forwardly and centrally with respect to the brush head. It' desired, the plate 22 may be notched for the reception of theinner end of the pointer guide therein.

As disclosed by Figure 2 of the drawings, a determined downwardl pressure upon the rear portion ot the brush headl will cause the brush 6 of the applicator to spread away from the brush 23, consequently leaving a space between these brush elements for the passage of paint or other 4marking fluid which will thus be directed onto the road surface for imprinting the line of demarcation thereon. Thus by adjusting the pressure applied to the brush head the quantity of paint delivered onto the road" surface will be regulated'. The outer and lower ends ot the side and guard' brushes 4c are inclined and only when a determined pressure is brought upon the. brush heads are these j edges of the guard brushes brought against the road surfaces. The guard brushes prevent 4the outward spreading of the mark made by the brushes 23 and 6. lVhen the air is shut off from the air tank on the truck the device may be tilted so that all of the paint remaining inthe pockets between the brushes 23 and 6 and likewise the paint remaining inthe cup 10 may be redelivered into the paint tank and the brushes are normally returned to initial position to close the paint outlet space therebetween. The device may be read-ily cleaned as the directing brush is removably attached to the brush head. Obviously the pr-esser rod need not be attached tov the link or eye but may have an angle end passing through one of the arms 18 or may be attached to another part of the construction. A

v The simplicity of the construction and the advantages thereof will, it is thought, be apparent without further detailed description.

Having describedy the invention, I claim:
