, In my copending application, Serial No.

374,257, filed Jan. 13, 1941, I illustrate and describe a paint striping apparatus of improved and simplified design enabling the application of a stripe of paint orother pigment to a surface by a continuous uniform stroke regardless of corners on the surface. The present invention relates to a tool of generallysimilar type, however in this instance the tool is so devised that it is capable of being employed in the striping of both horizontal and vertical surfaces, i. e., regardless of the angular disposition of the tool. Moreover, the present tool has improved work engaging guide or gauge means associated therewith and selectively usable in the striping of different types of work,- enabling a uniform straight stripe to be applied in predetermined relation to an edge of the work surface regardless of the plane in which the latter is disposed. This gauge structure in a preferred embodiment enables thestriping roller to be viewed at all times regardless of the disposition of the same to ascertain if a proper engagement of the parts is had.

Referring to the drawing, the reference numeral I in general indicates the tool of the invention which, like the tool illustrated and described in the aforesaid copending application, has a hollow cylindrical or tubular body 2 adapted to be gripped in the use of the device and separated interiorly by partition '3'to provide a paint or pigment receiving reservoir 4 which is spaced from the gripping portion of the body. This enables the latter to be gripped adjacent its end without transferring heat to the paint in the reservoir, which is commonly rendered suitablyfiuid by the use of a highly volatile liquid and readily subject to variation in its physical characteristics under the influence of temperature changes. l l

At its forward end, the body 2 at the bottom or lower side thereof is offset downwardly at right angles a substantial extent as indicated by the reference numeral5 and the upper forward edge or face portion 6 thereof is inclined at an angle of about 45. Offset 5 provides a bottom wall for a sump I into which paint or pigment from the reservoir 4 flows by gravity from the reservoir (being in fact a part of the reservoir) regardless of whether the toolis held horizontally as in Fig. 1 or vertically as, in Fig. 5. The sump is completed by a bottom side closure plate 8 secured by screws 9 to the body, the plate being laterally spaced at the forward edge ofthe body from the inclined forward body portion G-to receive th striping roller III which." is

tor or feed gauge member H, see Fig. 4, which slides longitudinally in undercut recesses or ways I 2 in the body adjacent the closure plate 8. This doctor has doctor or paint regulating surfaces [3 coacting with roller H] to regulate the thickness of the film of paint carried thereby. A spring [4 disposed between the doctor I I and one of the ways [2 takes up lost motion. The doctor is adjusted longitudinally in the ways by means of an adjusting screw [5 rotatably journaled in the rear sump defining offset wall portion 5 of 1 the body, this screw being threadedly engaged with a follower lug l6 secured to the doctor and being likewise restrained from longitudinal movement relative to the offset wall 5. The screw is provided with a knurled end for manual manipulation in adjusting the doctor.

Adjustably mounted on the forward inclined face portion 6 of the tool is a plate-like gauge member l8 having an elongated guide slot l9 therein and coacting with this slot to enable the gauge I3 to be longitudinally adjusted is a screw threaded into face portion 6 and receivable in the forward end 2| of slot [9, which is relatively narrow or restricted in width, the head of the screw overhanging the sides of this slot portion. Screw 20 has a fine bore therethrough serving as an air vent for the paint reservoir. At its upper and rear end, the slot I9 is enlarged somewhat in width at 22 to accommodate an externally threaded hollow filler fitting 23 which is fixedly engaged with the face portion 6 by means of the threads thereon. Threaded on the said filler portion is a clamp nut 24 which laterally overhangs the sides of slot portion 22 and engages the guide or gauge 18 to clamp the latter in adjusted position on the face portion. Member 24 is knurled to facilitate actuation and release thereof. A suitable filler member 25 is associated with the hollow filler fitting to enable the contents of the reservoir to be replenished when necessary.

At its lower forward end the gauge or guide member {8 is offset outwardly at an angle to provide a generally triangular or flaring plate-like guide 26 of substantial area adapted to engage the work in the manner illustrated in Fig. 1 to facilitate the application of a longitudinal stripe to the work, which is indicated by the reference numeral 21 and is, in the form shown, a portion of the frame of a refrigerator or like shelf or rack. In order to enable the coacting relation of the guide roller l9 and the work to be ascertained at any point in the striping movement, the guide 26 is provided with an aperture 23 of substantial size immediately over the roller l0, enabling a clear view of the latter to be had, as illustrated in Fig. 2.

' Referring to Figs. 1 and 5, it will be seen that the side of the sump portion of the tool body is provided with an adjustable set or clamp screw 29 receivable in a slot 33 in a further auxiliary guide or gauge member'3 l' on the opposite side of roller [0 which has an apertured guide surface or portion '32 similar tothe surface 26 offset at a right angle and projecting downwardly'beyond the roller If If necessary, the wall of the sump may be thickened by provision of a boss to receive the screw 29. Member 3| may be adjustably positioned longitudinally or angularly at any desired distance from the roller or at any desired inclination relative thereto to enable the top surface of horizontally disposed work or a variety of types of work to be striped with ease and rapidity. In the instance shown in Fig. 5, the work designated 33 may be any horizontally or otherwise disposed surface. I find that using a guide of t is ype the striping of automobile louvers and other irregular surfaces having but a single edge along which the tool may be guided is greatly facilitated.

In Fig. 1, I illustrate the relation of the auxiliary guide member 3| to the tool and the other guide or gauge l8. It will be appreciated that both guide or gauge members I8, 3| may be employed if the character of the work being striped indicates this to be desired, for example, in the case of a piece of work of additional width as indicated in dotted lines in Fig. 1, or either thereof may be removed, as would be necessary in manipulating the device in the manner shown in Fig. 5 on a surface 33 of considerable width.

The foregoing tool is simple, compact and inexpensive yet capable of being employed in the striping of many different types of surfaces. A steady uniform gravitational flow of striping liquid to the roller Ill is assured whether the same is employed vertically, horizontally, or at an intermediate angle, and the parts are visible to the user at all times. Adaptation of the tool for any desired operation by adjusting or removing the gauge or guide members l8, 3: is simply and quickly performed.

I have illustrated and described my improvements in an embodiment which is very practical. I have not attempted to illustrate or describe other embodiments or adaptations as it is believed this disclosure will enable those skilled in the art to embody or adapt my improvements as may be desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
