This invention relates to painting instruments and more particularly to a striping instrument.

An object of the invention is to provide an instrument for painting stripes on plain or curved surfaces.

Another object of the invention is to provide an instrument for painting stripes of uniform width throughout their length. Y

Another object of the invention is to provide a striping instrument adaptable for use in vario-us positions; that is, for painting vertical, horizontal or inclined stripes.

Yet another object of the invention is to provide a striping instrument having an automatic feeding means operated by the movement of the instrument over the surface to be striped.

A further object of the invention is to provide a striping instrument having a guide arranged for coaetion with a molding and a feeding means operated thereby for feeding paint with a uniform iiow.

A further object of the invention is to provide a striping instrument having a container for liquid paint and means connected therewith for feeding the paint through a nozzle in a predetermined and constant flow.

A further object of the invention is to provide a .striping instrument having a hollow handle for the reception of liquid paint and means connected therewith for automatically feeding the paint through a nozzle as the instrument is moved over a surface to be striped.

Yet a further object of the invention is to provide a striping instrument having an oscillatory nozzle provided with means for regulating the flow therethrough and for closing the nozzle when the flow ceases.

Still a further object of the invention is to provide an instrument for painting stripes of uniform width, an instrument which is positive in action, highly efficient in operation and yet of marked simplicity as a whole and in respect to each of its component parts, so that its manufacture may be economically facilitated both as regards to parts and their assembly.

Other objects of the invention will appear from the following description taken in connection with the accompanying drawing which forms a part of the specification and in which:

Figure l is a plan view of a portion of a panel illustrating the instrument in use,

Figure 2 is a front elevation of the instrument, partly in section, Y

Figure 3 is a longitudinal sectional view taken on line 3-3, Fig. 1,

Figure 4 is a cross sectional View taken on line 4 4, Fig. 3, and

Figure 5 is asectional view taken on line 5 5, Fig. 2.

Referring to the drawing for more specific details of the invention, 10 represents a body portion comprising a solid mass having formed integral therewith a hollow cylindrical handle 11. As shown,v the body portion is substantially V- shaped with the handle extending therefrom parallel to one leg and the other leg' is curved upwardly to meet the handle and to provide a heel portion 12.

The body portion has parallel overlapping transverse bores 13 and 14 in which are mounted 70 corresponding intermeshing gears 15 and 16. The gear 15 is keyed upon a spindle 17 journaled in suitable bearings 18 fitted in therespective ends of the bore 13, and the gear 16 is keyed upon a spindle 19 journaled in sleeve bearings 20 tted in the bore 14. rhe spindle 19 ex- "i tends through the bore 14 and projects from the resective sides of the bodyv portion. This spindle is provided upon one end with a wheel 21 and upon the other end with a guide roller 22. These guide members not only serve to mainl tain the instrument in position but in addition thereto provide an efficient driving means for the gears 15 and 16 which are positioned in and are a part of a feeding means to be hereinafter described.

The feeding means comprises a passage or passages connecting the bores 13 and 14 with the hollow handle 11. As shown, the body portion is provided with a bore 23 intersecting the overlapping portions of the bores 13 and 14 and normal to the axis thereof; hence, the bore 23 is in the path of the intermeshing gears 15 and 16. The lower end of the bore 23 connects with a bore 24 which-is normal to the bore 23 and extends rearwardly therefrom and the bore 24 is connected by a bore 25 to the interior of the handle, each of these bores being provided with cleanout plugs. The upper end of the bore 23 connects with a rearwardly extending bore 26 100 which, in turn, connects with a bore 27 extending transversely through the body portion.

The transverse bore 27 has mounted therein for oscillation a shaft 28 having upon one end an enlarged portion 29 bearing upon the side of 105 the body portion and threaded into the other end of the shaft is a screw 30 for retaining the shaft in position. The shaft 28 is centrally bored as indicated at 31 and is provided with a circumferential groove 32 positioned to register with 1(10 sii the bore 26 and this groove communicates with the bore 31 by means of a plurality of radial bores 33. The enlarged portion 29 has a lug 34 to which is attached one end of a spring 35, the other end of which is secured in the side of the body portion, the purpose of which is to limit the oscillatory movement of the shaft and to retain in position the nozzle to be hereinafter described. Extending through the enlarged portion 29 is a transverse bore 36 fitted into which is a plug 37 having upon one end a head 38 and threaded upon its other end as indicated at 39. This plug has an axial bore 40 and a circumferential groove 41. The groove 41 communicates with the bore 40 by way of radial bores 42 and the groove 41 communicates with the bore 31 in the shaft 28. Mounted upon the threaded Vend portion 39 of the plug is a nozzle 43 having therein a recess 44 in which is positioned a ball 45 urged by'a spring 46 to normally close the bore 40, the advantage of which will hereinafter appear.

The body 10 has oppositely disposed transverse bores 47, each communicating with the interior of the hollow handle 11. 'I'hese bores are normally fitted with suitable plugs 48, each removable and replaceable by a container or barrel 49 shown attached in Fig. 1. Both the barrel 49 and the handle 11 have a cap 50 provided with a suitable spring loaded valve 51 for the purpose of venting the barrel. The pressure on the spring loaded valve is such that the valve will readily open to vent the barrel when paint is being drawn therefrom. The barrel 49 and the handle 11 are each provided with a follower 52, shown in section in the handle 11. This follower is by no means essential but is useful when the specific gravity of the paint is such that an additional weight will increase the fiow thereof and retain the paint at the delivery end of the containers. The barrel 49 is changeable from one side of the instrument to the other so that the instrument may be made adaptable for either right or left hand use. This barrel is more particularly adapted for use in laying horizontal stripes or stripes in other positions in which paint would not feed properly from the handle owing to the position in which the instrument is held.

In operation, liquid paint is placed in the hollow handle 11 or the barrel 49 according to the use of the instrument and the position in which it is to be held for the particular work to be performed. The follower 52 is then placed in the handle or the barrel as the case may be, though such devices are by no means essential; they have been found desirable in the use of paints of Vvarious consistencies and specic gravity. The cap 50 is then threaded into the end of the handle or barrel and. thereupon the instrument is ready for use.

When the instrument is adjusted to the work, the guide wheel 21 and guide spool 22 engage the surface of the object to be striped. When in this position the nozzle 43 is yieldingly held against the surface to be striped by means of the spring 35. In this position the instrument is drawn over the surface to be striped and as it moves the guide Wheel 21, or as shown, the guide wheel 21 and the guide roller 22, rotate and thereby operate the feeding mechanism to draw the paint from the barrel or interior of the handle, as the case may be, through the passages in the body portion to the overlapping portions of the transverse bores in which the gears are positioned; here the paint is taken up by the gears and forced through passages leading to and through the oscillatory shaft 28 and the nozzle 43 past the spring pressed ball 45. When movement of the instrument ceases the gears driven by the guide members 21 and 22 stop, the pressure on the paint caused by these gears ceases and thereupon the ball 45 immediately closes the nozzle, hence, elfectually stopping further ilovv of paint from the instrument. In this manner a meastired or metered flow of paint is secured, the volume of which is constant for a given area of work.

By reason of the fact that the end of the nozzle is positioned substantially in a transverse line with the point of contact of the guide roller 22 with its guide, a stripe may be formed to a point immediately adjacent the end of the molding or other guide on which the roller operates.

Although this invention has been described in combination with certain specific embodiments the principles involved are susceptible of numerous other applications as will readily occur to persons skilled in the art. The invention is, therefore, to be limited only as indicated by the scope of the appended claims.
