1 fllai sw re This invention relates to a center stripe spray machine for spraying while lines along the center of a road.

This application is a continuation in part of my copending application filed July 11, 194?, with the Serial Number 5760225, and now aban doned.

It is an object of the present invention to provide a machine for spraying white lines along the center of a road which is provided with mocha. anism for timing the spraying of intermittent lines along opposite sides of a full center line wherein the stripe portions of the intermittent lines will be staggered respectively with the stripe portions of opposite intermittent" lines. Other objects of the present invention are to provide a center stripe spraymachine which is of simple construction, easyto operate and efficient in operation.

For other objects and for a better understanding of the invention, reference maybe had to the following detailed description taken in connection with the accompanying drawing, in which Figure 1 is an elevational view of- -a truck-body with'the center stripe mechanism of the present invention mounted thereon.

Figure 2 is an enlarged cross-sectional view taken on line 2-1 of Figure 1.

Figure 3 is a fragmentary longitudinal cross-e sectional view taken on line 3-3 of Figure 2.

Figure 4 is a fragmentary longitudinal cross-.- seetional view taken on line 4-4 of Figure 2.

Figure 8 is an illustrative viewof a highway having a full center line and intermittentlyspaced lines at opposite sides of the cer-iter line.-

V Figure 9 is a diagrammatic showing; of the electric control circuit used in the mechanism.

Referring now to the figures, t5 gepresents a truck chassis having a cab 16 from which the truck is driven. The operator in the cab I16 will locate a guide wheel l1 carried on a forwardly extending structure t8 on a center line which is to be painted. On the end of; the truclg chassis there is mounted a tank lswhich is filledwith the paint to be used. The paint is delivered to a'spreading device 2| by a pump 22'. The spreading device has outlets which are controlled by magnetic valve arrangements 23. The spreading device 25 is mounted on a slide, Figure 2, as in-.: dicated at 24 and controlled by a wheel 25 located at an operator s station 26. l

The slide 2-4 is mounted on a transverse guide member 21 which is connected to the opposite sides ofi the truck frame as indicated at 28. Depending trom the slide 24 are pipe members 29 in which are telescopically adjusted rods 3! which are connected to a transverse frame 32. Accord! ingly the spreader which includes the frame 32 can be mounted for vertical adjustment on the slide 24. The spreader further includes a transversely extending pipe 33 connected by a pipe 34 leading from a strainer 35. The paint carrying pipe 33 is mounted in hubs Ill and l I on the lower ends of downwardlyextended ends ofthe frame 32. The pump 22* delivers the paint to the strainer 35*. Raint accordingly is passed through the pipe 33 under pressure. This pressure will be indie cated bya gauge 36 Such paint which is not dispensedthroug h holes 31 of the pipe 33 will be returned to. the tank [9 past valve 31 and through pipe 38 to the top of the tank l9. By regulating valve 31' the pressure within the pipe 33 can be controlled.

On, the pipe .33. are a pluralityof perforated siee'vesAl', 4'2 and 4:3. These sleeves are extended over the slots 31: .in the pipe 33 and are rotated on the. pipe to..cause.- an outward flow of paint through openingslld. Each of the. sleeves have an. arm d5; extending upwardly therefrom and connected to a threaded shaft 4.6. extending from a olenoid 4.1. An adjustable stop. 48. will align the hole. 3"! with the. perforations 34 of the sleeve. On the; top.- of the. solenoid 41 is a relay switch 4:9. adapted when operated to. close. the circuit, for the solenoid 4.1:. This relay 49 operates a switch arm it, Figure 9. The. outer sleeves 42 and 43 are. operated by the. solenoid arrangements. These sleeves are resiliently held in assembled relation, springs. I12 and. 13 positioned between theouterends of the sleeves. and thehubs in and JH of the frame 32.

e'hentral sleeve .41 may be. operated man:-

1 y by aBowderr wire 52..

The line formed by-the central sleeve 4 I, is con-.- tinuous and serves as the center full line which divides the road. The sleeves 4:2 and 43. will make intermittent lines on lines with. gaps therein. These; intermittent lines are preferably twenty teat inv length. andare separated by a space of forty feet. The sleeves 42 and 43 are v turned to an open position alternately so. that one mark oncne 'sideofthe central line. will be staggered with respect to the mark on the opposite side of the center line. As between marks on opposite sides of the center line, they will be spaced relative to one another at distances of ten feet apart. While these spacings are suggested, it will be apparent that spacings of different distances can be worked out with the arrangement.

Extending upwardly from relays 49 are cables 54 which lead to a device or time switch for controlling the operation of the sleeves 42 and 43. This time device is indicated generally at 55 and the device is mounted on top of the truck frame 15. The device 55 is driven by a shaft 56 which machine, perforated sleeves rotatably mounted may extend from a speedometer or other measuring device. This shaft 56 drives a shaft 51 mounted in ball bearing units 58 within a sleeve 59 adapted to be raised by a hand control device 6| against the action of a spring 62 where-- by to disengage a worm gear 63 from a gear 64 which drives a disc 65 of insulating material. The worm gear 63 is on the shaft 51. When the gear 63 is coupled with the gear 64, disc 65 is driven to cause a contact plate 66 on the face of the disc 65 to pass bridging contacts 61 and 68. The bridging contacts 61 and 68 are mounted on a bracket 59 at diametrically opposite locations. The contact plate 66 extends for one hundred and twenty degrees. As the plate 66 passes under the bridging contacts, the sleeve connected with one or the other of the solenoids 41, will be operated to stop the flow of paint. The disc 65 is timed to make one revolution for sixty feet of travel along the road. If it is desired to operate one broken line at one side of the center line, one or the other of switches H and 72 are pulled to open positions. The source of power for operating the solenoids and the relays 49 is a' battery 13.

The operator sits in seat 26 and will operate various devices to cause the difierent paint stripes to be made. At the same time, he will operate the wheel 25 to shift the slide 24 and bearings I6 and H with the sleeves 4|, 42 and 43 on the pipe 33 to keep the sleeves and their paint openings properly aligned with the center of the road.

With the parts arranged in this manner the operator may drive down the center of a highway depositing the paint to form a continuous white line in the center, and when desired, intermittent lines may be placed at the sides 0! the center line by the sleeves 42 and 43 and these intermittent lines may be evenly spaced.

When an island is provided in the center of a highway as illustrated in Figure 8 one of the sleeves 42 or 43 is adjusted to the closed position and the other sleeve with the sleeve 41 are adjusted laterally on the pipe 33 whereby the lines pass to the sides of the island and after passing the island the sleeves are moved back to the center.

While my center stripe machine has been described for use with white paint it will be understood that any other kind of paint may be spread therewith. An asphalt stripe may be made and colored stone dispensed thereupon whereby to provide a more permanent stripe upon the road.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.
