Patented .lilly 11, 1933 EVER-ETT H. HOLLINGSHEAD, OF DAYTON, TEXAS LINE MARKER Application filed June 7, 1929. Serial No. 369,026.

The invention relates to an apparatus for V marking lines and is particularly useful on highways, streets and the like, although it is adapted for other purposes as will be obvious from the specification which follows.

It is an object of the invention to provide an apparatus for making a center line upon roadways, particularly the line used to separate the traffic upon the road. It is also useful in marking off parking areas along` streets or for other similar purposes.

It is a further object of the invention to provide a device capable of handling either paints or heated liquids such as asphalt which are to be used for marking purposes.

Another object of the invention is to arrange the device so that it will feed a continuous supply of liquid to the distributor or marking shoe at a uniform rate.

Still another object of the invention is to arranged the marking shoe'in an adjustable position such that it will not vary from the center line upon slight variations of the traction apparatus.

Another object of the invention is to provide an overflow device which will prevent the waste of the liquid.

Another object of the invention is to arrange the distributor or marking shoe in such a manner that the liquid may be shut ofi closely adjacent the discharge opening.

A still further object is to provide the` device with an arrangement of jacket Awhich j retains the heat about the distributor shoe as well as the storage tank.

@ther and further objects of the invention will be readily apparent to those skilled in the art when the following description is considered in connection with the accomvoanying drawing.

The present invention is an improvement over the apparatus disclosed in my prior co-pending application Serial No. 246,413,

F ig. lshows a vehicle comprising a single front wheel 1, and bearing 2 therefor. The wheel is adapted for rotation in the bearing 2 and is guided by means of a pair of spaced 6G rods 3 connected to a cross member 4, which in turn is fastened to the post 5. Y

A steering lever 6 is shownas extending rearwardly from the post 5 and resting upon a rack 7. l It'seeins-obvious that by manipu- 65' lation of the steering lever 6 that the machine may be guided down the road or wherever desired. The bearing 2 supports a pair of side members `1() ywhich extend rearwardly and rest upon the rear wheels 11. These frame members 10' support the tank 12 adapted to contain a supply of fuel. A pull bar 13 is shown as extending forwardly of the bearmg 2 so that the devicemay be attached to any motor vehicle or the like by which it may be propelled. Supported on the frame members 10 is a jacketed tank 15 for the marking liquid, which may be paint, asphalt or any suitable material. v 8O 'lhe discharge of the liquid from the tank 15 is accomplished by means of the control valve 20. This valve .is arranged for sliding movement within a pipe 21 and is controlled by means of the lever arm 22, which extends rearwardly for manipulation by the operator. In this manner by pushing downwardly upon the lever 22 the valve pin 20'is raised and, permits the escape of the liquid into the dis-V charge shoe. This shoe is shown in'rear elevation in Fig. 2 and comprises a jacket member 25 which surrounds the container 26. It will be seen in Fig. 1 that the jacket member 25 is adapted to slide within a somewhat similar member 27, which is supported from the tank 15. v

A burner 28, which is arranged vfor either gasolene, kerosene or fuel oil of any type, is shown as mounted adjacent the jacket 25 and arranged so that heat may be applied to the container 26. This heat as it passes about the container QG will arise thru the jacket and into the similar member A7 where it will pass into the jacket about the tank l5 and will not be dissipated. A. second burner 29 is shown as used for applying heat inside the jacket about the tank l5. These burners are used when it is desired to distribute asphalt or other material in heated condition. When paint is being distributed these burners are not necessary. Both the jacket member .25

and the container 26 are shown as supported upon a pair of bars 30, which are pivoted at 31. A suitable brace member 32 is shown as connecting the support for the bars and the frame members 10 so that a sturdy construction is obtained. The rear end of the bar members 30 carry akpin to which is connected a support rod 3ft, which in turn is connected to the adjustment lever 35. This lever 35 is shown as pivoted to the rack 7 and may be arranged in any desired position by means of a `quadrant and latch 36.

l Itwill be apparentfrom this structure that l by adjustment of the handle 85 theelevation of the shoe with respect to the surface being marked, which is indicated 37, may be had. IVhen the handle 35 'is moved downwardly the distributor shoe will be raised Vupwardly but will pivot about the pin 31,. The rod 34 is shown as ofA a special construction to allow limited movement of the distributor shoe in passing over irregularities in the surface being marked. This connection is shown in Fig. 3 where the rod 34 extends into a sleeve 38 and is adapted to slide down upon a bolt 39, which is placed in the slot l2 lwithin the rod 34.

The rod 34 also carries a stop pin 40, which is arranged to restrain one end of a coil spring 41, the other end of which abuts against the sleeve 3S. In this manner, regardless of the adjusted position of the handle 35, the sleeve 3S, which is connected to the pin 33, will be free for limited vertical movement when irregularities are encountered by the shoe. Y

The distributor shown is of a particular' construction'and consists of a valve housing l5, which is connected to the bottom end of` the container 26. This valve housing contains a cylindrical valve 1&6, having a longi-L tudinal Aslot 47 therein. This valve is reduced at 48 to receive anV armA t9, which arm is fastened upon the reduced portion 4S in any desired manner so' that ri'itation of the arm 49 will also rot.. l nected to this arm El is a' rod 50, which shown in Fig. l extending upwa diy to a handle 5l convenient for the operator. It will be seen that by pulling upon the handle 5l the eut-off valve i6 will be rotated and the position of the slot Li7 controlled. Be-

low the valve structure 4:5 is the contact-V shoe or nozzle 55.v This is shown as a block te the valve 46. CoinY of any suitable material having a passage 56 therein. The slot 47 of the valve 46 is adapted for alignment with this passage 5G and when in this position, such as shown in Fig. l, will permit a flow of liquid to the surface 37. As previously described, the flow of liquid may be instantly cut oil' by manipulation of the handle 5l to rotate the slot i7 out of alignment with the passage 56.

The block or noz/le is shown as formed with slanting faces and the passage 56 parallel to these faces. AThis is of advantage as these blocks soon wear away in constant use so that the leading and trailing surfaces in the present block will remain of the same width as the block wears away and no adjust-ment except of the handle is necessary to take care of the Wear.

By adjustn'ient of the valve Q0, by'mo-vement of the' handle 2Q. the iiow of fluid into the container 26 may bel controlled. A considerable supplyof iuid is usually maintained in the container 26, and, as shown in l, I have provided means visible to the of' erator to determine when thecontainer 26 about to overflow. This means consists of a rearward extension 58 upon the container 26. Upon this extension is mounted an overflow pipe 59, adapted tocarry a bucket GO. Tluis when the level of the [luid in the container Q6 reaches that of the top of the overflow pipe, the operator will notice the flow of' liquid into the bucket 60 and then may adjust the valve 20 to reduce the flow of liquid from the. tank. The bucket 60 prevents the overfiow from falling onto the roadway and disfiguring the line being marked.

In marking various highways the type of the material from which the highway is constructed varies greatly, some surfaces being pitted and rough, whe-reas other surfaces may be quite smooth. Upon the nature of the surface being marked" depends the amount of liquid to be discharged, and I have provided an adjustment of the distributorshoc to permit the escape of any desired amount of liquid. This adjustment is shown at and comprises a rod 71.I which isconnected at 7 2 to the forward side of the distributor shoe. By adjustment of the nuts 78 the base of the shoe may be moved forwardly or rearwardly as desired. It is obvious that when the base 74 of the shoe is in contact with the surface 37 that but a small amount of liquid may escape, but if the shoe is moved forwardly or rearwardly the shoe will rest at an angle on the surface 37 and a greater amount of liquid may escape.

From the foregoing description it will be apparent th at I have provided means to adjust the distributor lshoe both vertically and horizontally, so that irregularities in the road may be overcome by vertical adjustment and the amount of liquid be controlled by horizontal adjustment.

The particular placing of the. distributor shoe adjacent the rear traction wheels 1l is of material advantage as it will be seen that any variation of the wheel l from the line being marked will be materially reduced, due to the fact that the marking shoe is spaced a considerable distance therefrom and is adjacent the support wheels ll so that any side movement will be reduced in proportion to its distance from the wheels ll as compared with the distance between the wheels l and ll. In this manner a substantially straight line is marked regardless ol slight variations in the steering of the apparatus.

Another point of advantage is the pivoting ot' the support bars 30, which carry the discharge shoe at a point in front of the wheels ll and considerably in the rear of the wheels l. In this way, if the wheel l strikes an irregularity the shoe is not raised from the sur- :tace for the reason that the bars 3() are pivoted substantially in the middle of the apparatus andthe vertical movement of the pin 3l is reduced to a minimum. Thus when either the forward or the rear wheels pass over an obstruction the shoe 55 is affected but slightly. In this way no blotches or disfigurement of the line being marked occurs.

lVhen it is desired to stop the machine, manipulation of the handle 5l closes the valve 16 and only the liquid remaining in the passage 56 may pass out onto the pavement, it being the object of this construction to place the valve 46 asnear the point ofV marking as possible, so that when a halt in the operations is necessary no liquid will be wasted and no disigurement of the line will occur. As the valve 46 is closed, movement of the machine but a short distance will discharge the liquidl in the passage 56 and not blot the roadway.

The 'foregoing description sets forth what I believe to be a practical embodiment of my invention but it is obvious that slight variations may be made without departing from the spirit of my invention.

Having described my invention, what I claim as new is:

.In a marking apparatus, a supply tank, a discharge container, a valve operable to control the How of liquid from said tank, an over- Iiow linefor said container, a cutoff valve below said container to prevent escape of liquid therefrom, and a. discharge nozzle below said. valve and adapted to Contact the surface being marked, said nozzle including a block of rigid material with substantially thick walls inclined rearwardly and having a passage therethrough for marking material.

In testimony whereof I hereuntoaliix In signature this 2 3 day of May, A. D. 1929.
