This invention, as indicated, relates to painting machines. More particularly it cornprises an apparatus adapted vespecially for placing Zone marks upon paving to serve as guides for traffic. I

'In view of the long distances over l'which 'it is frequently necessary to mark traic lanes the use ofhandI marking devices is found to be too slow-a process and it is also one 'involving considerable danger for the persons making the same. The principal object of the present invention is to provide an improved type of wheeled casing having atank carrying alarge supply of paint and being adapted to distributev said paintfto the road surface ata relatively high rateof speedand'with even margins andfalong a perfectly'true line.r

'Another object of the inventionvis to provide'a power drive for a painting 'mechanism which will Vcause the applicatorY -belt making` contact with the'road surface to travel at the speed vof movement of 'themachine so that there is no frictionalcontact ofthe belt with the road surface. .A further' object of lthe invention is to provide various adjusting meansso that the applicator belt may be applied'toor removed from'the road surface with the minimum of eort.` l Other and further objects of the invention will appear in the course of the following description. To the accomplishment of .the foregoing and related ends, said' invention, then, consists of fthe means hereinafter fully described and particularly pointed out in the claims.

4The',annexed drawings and 'the following description set forth in detailfcertain mecha-l nism embodying the invention, such disclosed means constituting'however, but one of various mechanical forms in which the principle of the invention may beused.v

In saidannexed drawings: j Fig. 1, is a longitudinalf vertical section showing the construction of the painting machine with the applicator belt in contact with they road' surface; Fig. 2 is a front elevation of the painting machine; and FigQB is a detail view showing` an adjustable equalizing bracket for controlling the distribution vof the j curves forwardly Vwith its forward ledge paint transversely of theapplicator belt.

comprises a casing 1 of substantially rectangular fo rm,having at its forward end a pair of road wheels 2 connected to a transverse axle 3 which carries a drive sprocket 4. The trans verse axle is supported in lan auxiliary frame 5 secured to the frontend of the casing, said frame having' a pair of depending arms k6 having journals at its lower end within which the ends of'said axle Vare adapted to be rotatably received. At therearward end of said machine `a si.ngle 'trailer wheel 7 is provided,

said Wheel -be'ing swivelly supported in a journal 8 securedfto the rearward face of said body. Ateach side of the rearward portion of said casing a guiding handle 9 is provided by means ofj'which the operator may controlv the position of said machine and move it along the desired path at the rate of travel found most -advan'tageous. A similar handle 11 is provided'atthe forwardportion of the casing. At a'point approximately central; of

the casing 'a transverse pivot 12 is provided uponl which a jointed leverfsupport 10 for the paintjreservoirl is` pivoted.. Thev forward end ofJsaid jointed lever is provided with a handle 13 and adjacent thereto a spring catch 14 is provided to hold said jointed lever supportin several positions of adjustment. The paint reservoir comprises a rectangulaitankfor vessel 15 having a drain plug 16 provided centrallyof its under side." When it is desired to lill the reservoir 15, the latchv 1,4 is tripped to release'the jointed lever support 10 which may then be'nioved to the dotted line position shownin Fig. 1. The reservoir will v then rest upon theroad surface or adj a cent theretoljina position readily accessible..

Vlrdjscent tlieforwardfendi of the reservoirl acornpartmentY 17 is providedadjacent its upper portion with a perforated bottom or vided upon said casing in a position to receive rthe sid'efed'gesofthe paint reservoirwhen the ward portionvw ofthecasing, which drain pan i downwardly turned so as to enter'ove'r the oo i soreen 18 throughY which the paint isfreturned to the reservoir and is"strainediso as to remove all foreign material. A stop.4 19 is pro;

rearward edge of the paint reservoir. Transversely of the casing at a point adjacent to the l operative position of the paint reservoir a transverse pivot 21 is provided'upon which the pulley supporting frame 22 1s adaptedto swing. Said pulley supporting frame carries i adjacent its ends a'pair of rollers 23, 24, the

roller at the upper edge being provided with a flange and the roller carried at the-lower end having a plain surface. The vpivot Yfor the frame ispositioned closely adjacent and slightly above the pivot for the lower roller which permits said frame to have a greater swing at its upper end than at its lower end.

I ce

- Thus the flanged roller which serves asV a belt pulley may be turned to a position vertically ward road wheels 2 are carried. The depend-V v Vingarms are pivoted adjacent their upper ends to a pair of transversely extending cross bars of the auxiliary frame which thus permits considerable latitude of transversegmo-A tion of the supported parts so that they may accommodate themselves Vto inequalities in the surface of the pavement. Extending for-` wardlyV from said axle a pairof, supporting' arms 25 are provided which are ycentrally Vapertured to provide journals for the forward applicator belt pulley 26. VOn one end of the ,axle 27 of 'said pulley a clutchmember 28 is providedhavingv a pair of ratchet teeth Y 29 adapted tobe engaged by a'pivoteddog 30 ypinned to the outer surface of the pulley and pulley, spaced a short distance from said dog,

Vheld in engagement with saidratchet Yteeth lby means of a vspring and bracket 31, 32, A stop 33 is provided on the outer face of said to limit the motionthereof in an outward direction. Y Y axle. 3 ya pair kof supporting arms 34 are; provided carrying a pair of downwardly depend-r ing: extension arms 35,36, one of said extension arms lserving as a support fora frame Y member 37 :which is suitable apertured adjacent its ends lto receive the journalsof apair 'of small rollersl 38, 39. Y y Y Y A Vradius rod 40 is jour-naled at its forward end upon the transverse axle 3 and at its rear ward end extends through: an angle member., 41 bolted to the under side of the casing.. A

shock absorbing :spring 42 is mounted upon therearward end of saidradius rodand an Y Y adjusting nut 43 serves to .regulate Vthe tension of saidspring. Upon Vthe upper side ofV Extending rearwardly from they position and the pressure adjust-ing handle said angle bar a drip pan 44 is provided and adjacentV thereto a pair of applicator belt guides 45 extendin an upward direction.

Adjacent the forward upper edge of the casing a bracket 46 is provided upon which an applicator controlling handle V47 is pivoted. A link 48 is connected with said handle adjacent said pivot point and its lower end is looped about a pair of-yokes 49, 60, the ends Y ofk which are secured respectively to the supporting arms extending forwardly" and rear-l wardly of the transverse axle 3. At a point adjacent at which the link engages said yokes, a spring 50 is engagedy thereover and the upper yend of said spring is connected by means of a chain with the forwardhandle 11 of the apparatus; At tliepoint ofjunction of saidspring with the lower rend Vof said chain a screw-threaded plate 51 is provided i of said paint reservoir; and at a point above i and slightly'v rearwardly ofthe transverse pivot for said scraper plate a transversepivot 56 is provided for each of thesup'portl arms 57 of a vpaint equalizer bar 58;"Y Said bar as :illustrated in Fig. 3 comprisesla Vstirrupws haped member having a centralV portion cut away on itsy under side Vso as to throw a greater amount ofl paint toward the central portion of said applicator beltvas itpasses under said member. j 'f Y l l As is clearly shown in Fig. 1, the applicator belt 59 extends longitudinally ofthe apparatus with its rearward end at a higher elevation than its f orwardend. The pnllev supports for the applicator beltat theforward portion of said casingfare vadaptedto. hold the same inoperative ,contact with the surface of the paving to be coated when-the applicator handle 47 `is turned to a downward has been adjusted to ythe proper extent# When Vsaid applicator handle is swung to-,an

pulley and thelrearward end of whichis .con-V nected with the' downwardly projecting arm/ Y V36 upon the rearwardly extending supporting Y bracket arm34, heretofore described;` Tfhe figa-sass ulle wheel at the rearwardnortion of said casing is in operative position against the stop 64, shown in Fig. l, that tension will be placed upon the applicator belt and it will be rotated rearwardly over the pulley immersed within the paint of the paint reservoir and thence will pass around the flanged pulley beneath the paint equalizing strirrup and through the belt guides and over the pulleys adjacent the lower front end of said casing l and into contact with the pavement. rlhe belt will then pass upwardly over the scraper plate and again will start its travel over the paint applying pulley. Thus there will be continuously applied to the outer side of the belt a film of plaint from the paint reservoir which will be distributed over the belt as it progresses downwardly beneath the paint equalizer and will be brought to the required degree of adhesiveiiess as it reaches the surface of the pavement. The rate of travel over the pavement of the applicator belt is equal to the rate of .forward progression of the apparatus so that there is no friction between said belt and the surface of the pave- Y ment.
