H. A. EMMONS HIGHWAY MARKER Filed Sept. 15, 1935 2 Sheets-Sheet 2 Patented Dec. 29, v1936 'UNITED STATES PATENT OFFICE HIGHWAY MARKER Herbert A. Emmons, Bloomfield, N. J. Application september 13, 193s, serial No. 689,220

'J Claims.

This invention relatesl to means for painting surface markers on roads, intersections and elsewhere, and particularly to wheel supported devices carrying means for this purpose, irrespective of whether propelled by hand or form a part of or be drawn by animate or inanimate force.

The general object of this invention is to place marks, lines, stripes, patterns, geometrical patterns and other colored designs and indicia on a` traveled surface discontinuously or intermittently as desired, by mechanical arrangements described and illustrated in this specification, said patterns', designs, stripes, etc. forming the subject matter of my co-pending application Serial No. 688,627, led September 8, 1933. By means of my invention herein specified and claimed, it is possible to paint but a portion of the line, stripe, etc., so that a considerable economy in paint and labor is effected, and at the same time produce a traffic guide of desirable legibility both in the daytime and night-time.

Other objects of my invention are concerned Y with constructional features of the mechanism lfor readily, accurately and properly placing the discontinuous line, stripe'orpattern on a road bed or elsewhere as desired, I have illustrated my invention as applied to a hand or pushed marker, but it is to be understood that I do not limit my invention thereto, as my mechanism may be 30 mounted on an automobile or horse driven vehicle, the manner of propulsion not being claimed as new by me.

Referring to the accompanying drawings:-

Fig. 1-is a top view of a highway marker constructed in accordance with my invention, the source or nature of the operatingI power being immaterial, but indicated in this illustrative figure as being operated by hand.

Fig. 2 is a vertical plane elevation of the marker 40. shown in. Fig. 1.

Fig. 3 is a vertical elevation of the paint applicator, viewed from the right of Fig. 1, Fig. 3 may be mounted on, or in connection with a motor driven, horse driven or otherwise non-manual driven mechanism.

Fig. 4 is a partial top view showing one alternative means of controlling the operation of the applicator in order to properly layfa discontinuous or geometrical pattern or stripe.

50 Fig. 5 is a fragmentary elevation of the device shown in Fig. 4, while Fig. 6 is a front elevation of the paint applicator showing (in this instance three) a plurality of paint' spray guns, which are controlled by the cams.

Referring to these drawings, in Fig. 1, is designated a' frame I of immaterial construction or dimensions, on which is mounted the paint applicator and the controlling mechanism, the frame being supported as by wheels 2 and propelled and guided by handles 43. It is to be understood that mechanism embodying my invention, instead of being mounted on a chassis" of its own, may be mounted on, attached to or laid upon a motordriven or horse-driven truck or the like, as mayV be desired. I

Mounted on the frame I is engine 3, carrying sprocket 4, connected by chain 5 to sprocket 6 which causes operation of air compressor 1, theI latter being suitably connected by means of pipe 3 to air receiver 9, provided with a pressure relief valve as I0. From air receiver 9, suitable piping 28 conveys air to paint tank 29 of any desired capacity, and by means of pipe 39 and flexible connection 3| air is conveyed to paint gun 34. The paint gun is mounted on slide 39, which is supported on rollers 40 riding in frame 4. The frame 4I is mounted on bracket 42 fixed to frame I.

From paint tank 29 the paint is conveyed by .pipe 32 and flexible connection 33 to the paint inlet of paint gun'34. Air for 4actuating the ram 23 and slide shifter cylinder 31 is taken from pipe 8 through shut off valve I I and piping I2 to slidevalve mechanism I3. Valve II is used to shut off the air from the slide valve mechanism I3 when the machine is being moved from one painted point to another where it is desired to continue painting.

Sprocket I4 attached to any one of the four wheels 2 is connected'by chain I5 to sprocket I6. This I6 drives slide valve 20 of the slide valve mechanism I3 by means of eccentric I1, push rod I8 and lever rod I9. Air is obtained from valve mechanism I3through pipe2l and flexible connection 22 for operating ram 23 mounted on shifter slide 39. The ram plunger 24 is located preferably over the trigger 25 of paint gun 34. As valve mechanism I3 allows the air to flow into the cylinder of ram 23, plunger 24 is moved (in this instance) downward operating trigger 25 of paint gun 34 which sprays the paint downward on the road or other surface to be marked or striped.

As frame I is moved forward on wheels' 2, valve mechanism I3 releases air from ram 23, thus permitting trigger 25 to shut off paint and air from gun 84. As the forward motion of the vehicle is continued, valve mechanism I3 also supplies and releases air through pipes 26 and 21 alternately, to the right and left hand inlets 36 and 35 of the slide shifter cylinder 31. This operates plunger 38 which is attached to gun mounting slide 39, As air is admitted to inlet 35, the slide moves to the right; when air is admitted to inlet 36, the slide moves to the left. By proper design of I3 the operation of 23 and 31 may be so arranged that any desired length of painted stripe to unpainted portion may be laid where one or more substantially parallel lines are used in any discontinuous manner as shown in my aforesaid co-pending application.

Referring to Figs. 4, 5 and 6, wherein is indicated means for mechanically controlling the paint applicators, I is the frame, 2 the wheels, on one of which wheels is mounted a sprocket I4 propelling chain I5 and sprocket I6. The latter is mounted on a suitable shaft 44 carried by bearings 45 mounted on frame I. As shaft 44 is rotated sprocket 46 turns, and by means of chain 41 and sprocket 48, cam-shaft 49 is rotated, thereby rotating thecams 50, 50a, 50h. A clutch 53 is provided on shaft 44 so that by moving lever 54 the operation of sprocket y46 which controls the cam operation, may be started or stopped -at will. Shaft 49 is mountedin suitable bearings 5I mounted on bracket 52 which is rigidly attached to frame I, and 52 performs a similar function to 42 in Fig. l. The paint guns 34, 34a and 34h are mounted on bracket 52 in such manner that revolution of cams 50, 50a, and 50h operate triggers 25, a, and 25D in a predetermined manner.

Paint may be conveyed to the paint guns through pipes 33, 33a, 332) and air may be conveyed thereto through pipes 3|, 3Ia, and 3Ib in the same or similar manner as in the compressed air controlled machine.

It is to be understood that other devices and arrangements may bemade in, or substituted for certain elements as indicated in the foregoing description of my invention, still conserving the breadth of the same. For instance, it must be obvious to one skilled in the art to which this invention appertains that if a properly designed commutator were substituted for valve mechanisms I3 and magnets were substituted for ram 23 and shifter cylinder 31, and these were properly connected to a source of electrical energy, the operation of the machine would be substantially as described in the foregoing.

One method of carrying my invention into effect in the operation of the machine is as followsr- After starting the engine of the marker (which I can lay but one pattern at a timewithout substituting another timing mechanism) and seeing that 29 has a suilicient supply of paint therein,

the machine is placed in position and valve II is turned to the on position. The vehicle is then propelled in the direction and at the position the stripe is to be made. When the end of the section desired to be paintedV is reached, the operator turns valve I I to the off position, thus shutting off the flow of paint by stopping ofi" the air from 23 and 31.

What I claim and desire to secure by Letters Patent is:-

1. A road marker comprising a metering wheel for contact with the surface to be marked by paint, a paint applicator, an automatic timer operated by said metering wheel to control the operation of` said applicator, a source of power, an air compressor, a paint tank, suitable connections from air compressor to paint tank, and
