Application filed October 9, 1922. seri 'inb. 593,465.

This invention relates to. a device for marking pavements. I I It is a primary ob ect of this invention to produce a practical mechanism for apply out upon said surface. It is also my object to provide means for permitting the machine tobe used readily on curves and to be turned around when desired- I It is a further object of this invention to provide a machine having acentralized control; to provide means for cleaning the pavement in advance of the marking roller may be used upon either side of the deviceto apply to the sub frame 17 a portion of the weight carried'by the main frame and thereto provide a marking roller of peculiar construction particularlyadapted for this service; and to provide means for. supplyingmarking fluid in a manner adapted to cooperatewith a marking wheel to distributethe fluid effectively and in a line upon the pavement. I .In the drawings; I

Fig. 1 is 'a plan view ofa, pavement mark-q ing device embodying this invention.

Like parts arei'dentified by the samereference characters throughout the several views. I I

In appearance,.tlie present embodiment of this invention resembles a-wheelbarrowpto some extent. Converging frame members 5 and. 6 are provided with handles 7. at their outer and upper ends and are provided at, their lower and inner ends with 3ournals '8 adapted to receive the axleshaft9 of the marking wheel 10 and adapted to support,

said frame members. I This Wheel can conveniently be'built up of several laminations of vvood, as shown more particularly in- Fig. 3.

he device differs from :a wheelbarrow; I however, 'in that small supporting wheels 12 arepreferably provided. 'These may" conveniently be disposed at thellower extremi ties of vertical frame members13. A platform 14: is supported as illustrated by means at some distance to the rear ofthe forward ends of said members by pivot bolts 20'. A

lead wheel2l which is preferably leather "r enterv faced at 22 is journaled for rotation at the r forward end of subj-frame 17. The lead wheel 1s positively, although resiliently, urged in the direction of the pavement by a spring 24: confined between a bracket 25 carried by the main frame member 5 and a nut 26 upon the fitting. 27 carried by the sub frame member 18. A- similar arrangement by to maintain the lead wheel 21 in positive a contact with the pavement. I

I and immediately ahead of marking wheel 10, there is preferably provided a pavement cleaning-brush-30, the handle 31- of which be utilized to draw the brush forwardly about its pivot upon'transverse member 32 and thereby bring-it the more effectively into contact with the road surface.

Adjacent the transverse member .32 or otherwise connected to sub frame '17, I preferablyprovide a cord 34: which runs over a pulley 35 supported from the main frame or from the platform thereon ,to a hand lever 86. When this lever. is pulled rearwardly about itspivotpoint- 37 until the cord passes across the center represented by point 87, lever 36 will come to rest and will be Upon. the platform 14:, I provide. a recep I tacle or tank 40. which may besecured, theremaintained in position by a stop 88 which will'resist the pull upon cord 34, tending to rotate lever 36 further in the same direction. The operation of lever 36 to the position cover 42 the markingfinid .to be appliec '5 l l to by bolts 41 or by any othercapproved wardly; Fluid delivery through said pipe is controlled by a valve therein. The'handle 4-4 of said valve is represented clearly in Fig. I and-is shown to be normally retained" infthe positionin which it is iillustrated in said figure bya spring 45. The V-alve may conveniently be opened, however, by means and linkAS. "means oi? the pull'rod e6, 'fluid" will flowthrough pipe 6L3 and will be d elivered in the" form of aian shaped jet throngh the ot-aq-m ll rod L6 extending t'oa positioirivithin. the grasp of the operator and connected with handle l-l .tl'irou'gh the bell-i crank l'l hen the valve is opened by flar- The flaring' en'd' of the pipe illustrated at 48:- is-dow wardly curved as clearly shownin Fig. '2 and extendsinto close prox imity to the peculiar marking pad "upon the ma'rkingwheel 10; This marking pad may be-lposit'ioned upomhe wheel in any desired nianner.' In the "present ei'nbodiment of my invention, I have illustrated'a fiang'e'dahn- .iniirki'ng l pad recf'eivable Within said rim preferably comprises a porous outer' surjt'ace' O o'fsomematerial of; considerable strength adapted, to stand the Weanoc'ca'sioned by its I operation Q over (road surfaces.

v -Ihus, during the forward operation of the device the liquid flowing upon the top of the marking wheel is brought by the rotation of the-wheel to the pavement and is applied thereto to PI'lIlt upon the pavement a line or lm'arklng conforming" in width to the pad i upon the marking wheeland of any desired" lVhena curve in the highway is encoun- 'tered orvvhen 1t 1s desired t'o turn the machine -around,lthe handle 36 fwill be drawn" 'reaiwardly and across-center whereupon-it will be=brought to rest by stop 38. The sub 'frame l7-will thus be elevated and will lift from the pav'einent the lead or guide wheel 21 and the brush 30, WVhen'the curve has been rounded and substantially straight higliwayf is again encountered, a reverse movement-of handle 36wvill5permitthe lead wheel 21 and i so i brush 30 to drop aga in upon the pavement.

l/Vhen the marking operation is Complete, the pull rod 46 will be lifted slightly to release notches 54 from engagement with pin 53 whereupon the tension of spring 45 will close the valve by rotating. handle 4a to the position in which it appearsin Fig. 1;

It will be seen from the-foregoing that the objects specified for this invention are fully satisfied by the device herein disclosed.

Various changes may be made, however, without departing from the spirit of my invention. For example, I do not wish to be limited to any particular kind of marking fluid, and obviously paint may be used, if

desired, instead of :a'coal tar derivative. It

has been my experience, however, that paint will not satisfactorily adhere to the pavement and, for this reason, the coal tar derivative is preferred. 2r 1 The marking wheel may also be changed in structure without departing from. the

.spirit or purpose of my invention. The wheel has been described as beingprovlded with'a peripheral absorbent pad. for apply ing the marking fluid to the pavement, but it will be understood that the principle of applying the marking fluid by the rotation of a wheel rolling upon the paved surface 1s more important than the particular construction of wheel which is used to accomplish the desired result.

lVhile theforegoing description has related solely to a manually propelled embodiment of this invention, I wish'to make it clear that in a broad sense, it is immaterial to my invention whether the marking wheel be manually propelled or whether it be driven by or attached to or drawn from some other vehicle, such as a horse drawn vehicle, or a self-propelled vehicle, such as a motor truck.
