Claims. (Cl. 9162.6)

This invention relates to and has for an object the provision of an improved type of fountain striper for the application to ornamented surfaces of stripes formed of pigment or water color paints arranged insa compact form', simple inform, economical in ist and operation, and capable of adjustment for forming a single stripe of desired width or a plurality of parallel stripes, in a single operation. I

To this end my invention contemplates the provision of a tubular body closed at its opposite ends and provided with a manually adjustable plunger with an operating stem projecting from one end thereof and a removable closure at its other end whereby a quantity of paint may be inserted in the body and fed outwardly therefrom when pressure is created in the body by movement of said plunger.

A particular feature of the invention consists in the provision of a sensitive adjustment whereby an applicator wheel carried on the removable closure at the end of the body may be adjusted relative to an outlet for the paint, for regulating the iiow of the paint from the body.

Another object is to provide on said closure an applicator wheel having diagonally disposed or herringbone serrations, or millings, for receiving the paint from the body, kfrom which the paint is transferred to a surface to be striped, as the wheel is rotated over the surface.

A further object is to provide a plunger formed of compressible material such as cork, felt, rubber or the like, confined on the plunger stem between a pair of plates or washers, and adjustable, so that when the plunger head is longitudinally compressed it will be expanded radially and thereby compensate for any wear on its periphery which may be occasioned by constant and continued use. Other objects may appear as the description progresses.

I have shown a preferred form of device, embodying my invention, in the accompanying drawing, subject, however, to modification, addition and abridgment, within the scope of the appended claims, without departing from the spirit of my invention.

In said drawing:

Fig. 1 is a perspective view `of the assembled device operatively positioned upon a surface to be striped;

Fig. 2 is a longitudinal section, in elevation, of the same:

Fig. 3 is a transverse section of the same on line 3-3 of Fig. 2;

Fig. 4 is a fragmentary longitudinal section, at right angles to the plane of Fig. 2, on line 4--4 of Fig. 2:

Figs. 5, 6 and 'I are views of dierent forms of applicator wheels capable of use in connection with the striper shown.

The device includes a tubular body I of circular cross section, a rear end closure 2 detachably held on the body, a plunger 3 slidably held in said body, an applicator head 4 detachably held on the front end .of the body, a universally adjustlable guide 5 and an adjustable guide support 6 carried on the body I.

Plunger 3 includes a stem I having a finger button 8 on its outer end and a head 8 on its inner end formed of cork, felt, rubber or other compressible material. Closure 2 is preferably threaded internally of its flange III so as to screw onto the externally threaded end portion of body I, and said closure is bored centrally so as to slidably receive the extended stem l. y

Plunger head 8 is adjustably held on the inner end of stem 1 between a pair of spaced washers II and I2, and `nuts I8 and I4, respectively, are threaded on said stem adjacent said washers so that the head may be longitudinally compressed and correspondingly expanded radially for causing the periphery of the head to frictionally engage the inner periphery of the body I.

'I'he front end of the body I is also externally threaded to detachably receive a collar I5, as shown in Fig'. 2, and the applicator head 4 is externally threaded at its rear end so as to detachably engage a portion o1' said collar. Applicator head 4 is of tubular cross section corresponding to body I externally and internally and has an' end wall I8 with a centrally formed inwardly extended boss I1 which is bored and threaded to receive a screw I8 having a head I8.

The applicator wheel is rotatably held at 2| between and on a pair of spaced

arms

22 and 23 formed on the lower portion of a bracket or holder 24 which is adjustably carried on the front end of head 4. Said bracket is of rectangular cross section and is slidable in a diametrical groove 25 and hasan elongated aperture 26 through which the screw I8 extends while the head I8 .overlies the outer surface of the bracket, as shown in Figs. 2 and 4. The upper end of bracket 24 has a forwardly projecting lug 21 thereon in which 'an adjusting screw 28 is threaded and the inner end of said screw abuts or is otherwise associated with the head I9 of screw I8 in such a. manner that the turning of screw 28 in one or opposite directions will adjust the wheel 20 outwardly from the head 4, or inwardly and outwardly, as may be desired.

By reference to Fig. 2 it will be noted that the forward end of head 4 has a slit 29 therein into which the wheel 20 projects so as to come in contact with the painty which is-contained in the body I and head V4. Thelwheel 2l) is adjustable inwardly or outwardly of said slit by means of a knurled button or knob l38 on screw 28 to ,an

extent depending upon the thickness or density of the paint used. Obviously aV water color paint will require that the wheel!! be adjusted ver! close to the margins of the silt Il in order to prevent 1eakage,'while a thicker paint will require a looser adjustment of the wheel.

`'Ihe guide holder l is preferably formed oi' a split ring with laterally extended abutting ends 3i and 32 connected by means of a bolt It, and diametrlcally opposite said ends a post I4 is rigidly secured to and extends radially from the ring, as shown in Fig. 1. for holding the guide I at desired angles relative to thev body I and to a supporting surface as at Ill. 'I'he guide l may be of any suitable form whichv will render it adaptable to universal use, regardless` of the position of a stripe on a surface. Asl shown, said guide may be bent into such form as to provide

end portions

36 and 31 and an intermediate portion 3l"whereby the'guide may be adjustably held in the'post 34 at one of the end portions and the other end portion may be disposed adjacent an edge of the surface to be striped. The

post 3l is longitudinally bored and threaded to.

receive set screw 3l andis diametrically bored at right angles, as at 'Il and 4I for .selectivelyl receiving the end portion I1 of the guide I, so as to render the `guide universally adjustable relative to an edgeor portion of an adjacent plane surface which itmay be desired to stripe.

4As shownv in Figs. 5,6 and k'7., the applicator wheels 20 may be of different form so as to apply narrow, wide or multiple stripes to a surface, and

, lto this end the Vapplicator head 4 is provided in Aseveraldifferent forms which are'rselectively attachable to the body i, The wheel 2l mayhave a pairor more of striping surfaces as at 8l and lll in Fig. 5, oi' corresponding width, orof different width as shown in Fig. 6"at ll and l2,

or a single surface llasfshownin Fig. 7, of sub stantial width, or otherwise. For multiple stripy ingY the paint applying surfaces are separated by annular grooves as at '44, and in all cases said surfaces are milled' diagonally as shown'in Figs.

y 5 and 6 orherringboneQ-like as in Fig. 7.

A In operation, a selected applicator head l with a suitable applicator wheel 20 is attached to the e forward endof body I'aftersaid body forwardly ofthe plunger head `l lbeen filled with a suitable paint, and afsuitable-guide l is attached to the holder Il and adjusted so that an outer' end portion thereof will engage a margin. side or portion of the ysurface w bestriped or a sur- Y Y face adjacent thereto.' The plunger l is then forced inwardly soas to compress the paint in 1 the forward end of the-body, and :the wheel 2l is adjusted inwardlyk orlou'twardly relative to the bodyi so yasin'` freely feed the paint from the interior of the body to the periphery of the wheel.

-When the device is positioned as shown in Pig. ,L

or otherwiseA according to obtaining conditions,4

and moved `*forwardly or -lbackwardly over a surface,as at 35, the paint will be received and carried by the milled peripheryof the wheelV and applied toI the surface `may be intermittently kmoved forwardly in the body for-maintaining sufilcient-pressure to expel the paint in a striping operation. The device is readily cleaned -by removing the end closure 2, theapplicator head l and the plunger I, and said plunger may beadjusted to compensate for wear on the periphery of its head l by tihtening the ing an outlet, a bracket diametrically slidable on said head in a plane at right angles to the axis of said body, a rotatable applicator carried by said bracket and having its periphery disposed adjacent said outlet, and cooperating means nxed to. said head and adjustable on said bracket, for adjusting said applicator relative to said outlet, in a striping operation.
