13 Claims.
This invention relates to a machine for applying a paint stripe to a highway, and particularly to one for applying paint in the form of an interrupted rather than a continuous stripe, and which results in a considerable saving of paint.
The principal object ofv my invention is to provide a mechanism for the purpose by means or penser functioning automatically with the ad-- vance of the machine.
A further object of this invention is to arrange and control the operation of the bead dispenser so that such operation will be automatically halted while passing over the unpainted spaces or interruptions between the stripe sections, but
' will be resumed as soon as thestripe painting is resumed. Here again a considerable saving in beads and a resultant saving in expense effected.
It is necessary at intervals to apply paint over an old striping, and another object of the invention is to provide control means for the paintgun actuating mechanism so arranged that the new stripe may be accurately superimposed over the old one without any overlap at either end.
The machine is mounted on pneumatic-tired wheels, the rotation of which controls the functioning of the paint control mechanism, which is designed to give a predetermined paint-stripe length and spacing with wheels of a predetermined operating diameter; If the effective wheel radius or diameter varies, due to variation in tire inflation or weight of the operator on the machine, the operation of the paint control mechanism will thus likewise vary. It is therefore another object of the invention to arrange the paint control mechanism so as to enable the functioning of the same to be compensated for any such variation in wheel diameter, so as to enable the paint stripe sections to be maintained at such predetermined length and spacing.
Other objects of the invention will be apparent from a perusal of the following specification.
In the drawings similar characters of reference indicate corresponding parts in the several views:
Figure 1 is a side elevation of a stripe painting The machine machine as in operation, the conduits leading to the paint spray gun and bead dispenser cylinder being shown somewhat diagrammatic, and only those conduits which are essential to an understanding of the invention being shown.
Figure 2 is a fragmentary enlarged sideelevation showing the driving and control mechanism for the air supply control valve.
Figure 3 is a fragmentary top plan view of the machine showing the mechanism depicted in Fig. 2.
Figure 4 is a fragmentary top plan showing the mounting of the bead dispenser and its associated air lift cylinder and bralge.
Figure 5 is a fragmentary side elevation showing the bead dispenser, air lift cylinder, and brake unit.
Figure 6 is a front view of the control valve unit, with the cover plate removed and with the valve rotor in the position occupied when at the I outset of a painting operation.
Figure 7 is a sectional plan of the valve substantially on the line 1-4 of Figure 6.
Figure 8 is a view similar to Fig- 6, but showing the valve rotor as positioned at the start of an air-exhausting movement from the paint guns, or when the painting operation is halted;
Figure 9 is a sectional planof the valve substantially on theline 99 of Figure 8.
Figure 10 is a fragmentary front view of the cover plate of the valve partly in section. Referring-now more particularly to the characters of reference on the drawings, the machine comprises a horizontal frame structure I supported at its rear end by a pair of pneumatic-tired wheels 2 and at the front end bya pair of steam able wheels 3. Steering of the latter is controlled from a steering wheel mounted on the frame convenient to the operators seat .5, also mounted on the frame adjacent its rear end. is not self-propelled, but; is adapted to be pushed ahead bya vehicle 317-: tached to .a rear end clevisB on the machine,

and air compressing unit thereon. I
A number of paint spray guns I are supported in, fixed connection with the rear end of an arm unit 8 which extends forwardly to pivotal connection with the frame I, as at 9; so that the guns may giv e vertically and also be lifted clear of the road; such lifting being effected by any suitable means, such as a lever and link mechanism, indicated at l0;
' ing from the adjacent portion of frame l.
the stripe painting is begun. The bypass passage 52 in the disc (10, and which controls the release of air from the cylinder ii, are therefore set back the proper distance iromthe slots $8 in the outer disc 39 and which control the flow of air to the paint gun. This distance may be accurately controlled or adjusted by turning the valve disc 48 relative to the disc 39 upon suit-- able manipulation of the driving set screw 56 which connects the discs. (See Fig. 6.)
In order that the valve as a wholemay be prop erly, set at the outset of a painting operation, a gauge finger 51 i mounted on the arm 22 and is adapted to read against one at a time of a pair of opposed pins 58 on the adjacent sprocket wheel tin of the chain drive 52 (see Fig. '3). At the outset of an operation, the wheel 2i is turned by hand, if necessary, to dispose-the pointer in register with either pin, and when in this posi-= tion the valve is about in position to initially admit air to the paint gun cylinder to start the flow of paint.
This arrangement makes possible the accurate synchronization of the valve with the point of beginning of the painted portion of a stripe, when a restriping job is being done.
When the bead dispenser is raised, it is desirable that the timing of the bead dispensing,
which is controlled by rotation of the wheels it, shall not be disturbed. I thereioreprovide a flat brake strip 66 above one wheel id in position to be engaged thereby when the dispenser is lifted (see Fig. 5). termediate its ends on a horizontal axis, on a vertical stem iii turnable in brackets 62 proiect- This stem is normally prevented from rotation by a releasable holding pin 53 between the stem and e. quadrant formed on the upper bracket 52 (see Fig. 4). A tension spring 6% between the free enchof the strip til and the stein resists upward movement of said strip. Rotation of the stem,
which causes the brake strip to swing also, is

While this machine has been particularly de= signed to control highway stripe painting op erations, said mechanism may be used for other purposes for which it may b found suitable.
From the-foregoing description it will-be read ily seen that l have produced such a device as substantially fulfills the objects of the invention as set forth herein.
