1 Claim. (Cl. 15-132.')

This invention relates to a rotary striping wheel paint striper of the general character which are illustrated in the Coombs Patents Nos. 2,122,858 and 2,582,861.

The rotary striping wheel paint stripers which are illustrated in Coombs Patents Nos. 2,122,858 and 2,582,861 generally include a striping head to which is detachably mounted a paint storage container in the form of a collapsible tube container, bottle, for holding paints or similar surface striping materials. While the paint stripers shown in the aforesaid patents are satisfactory for their intended purposes, it has been found from experience in the use thereof that under one particular operating condition, namely, when attempting to stripe upon a vertical wall or like surface, it did not operate satisfactorily and it is a principal object of the present invention to provide a paint striper which in use overcomes that ditliculty, namely, the diliiculty experienced in the use of prior striping devices when striping upon a vertical surface.

Thus in the use of the rotary striping wheel paint stripers, such as are disclosed in the aforesaid Coombs Patents Nos. 2,122,858 and 2,582,861, it is sometimes desirable to apply a paint or similar stripe upon a vertical wall surface, or upon the vertical surface of a piece of wood furniture, or the like, and for this purpose it becomes necessary to hold the striping head and striping wheel unit in a generally horizontal position against the vertical surface, but when so arranged, the paint storage container attached to the striping wheel will also be arranged in a horizontal position, with the result that the paint does not tlow freely therefrom through the striping head and onto the peripheral surface of the striping wheel unit.

Accordingly, an object of the present invention is to' provide a new and improved rotary striping wheel paint striper which is adapted to overcome the aforesaid difiiculty experienced in the use of the paint stripers disclosed in the aforesaid Coombs patents, and to provide a rotary striping wheel paint striper which may be effectively employed in striping paint or like striping material on a vertical wall surface such, for example, as upon a vertical wall surface or upon the surface of a piece of furniture or the like.

Another object of the invention is to provide a new and improved rotary striping wheel paint striper, which is so designed and constructed that in the use thereof, when stripin y upon a vertical surface, the striping wheel and striping wheel holder jaw head or assembly embodied therein may be swivelly moved relative to and upon the storage container and the coupling member by means of which the striping wheel and striping wheel holder jaw assembly are coupled to the storage container so that the striping wheel and striping wheel holder jaw assembly may be arranged at an acute angle relative to the storage container and coupling member so that the paint or similar surface striping material will readily flow from the storage container by gravity through the striping wheely and striping wheel holder jaw assembly onto the peripheral surface of the rotary striping wheel unit, even though the striping wheel is arranged in a generally horizontal plane for striping upon a vertical wall or like vertical surface.

A further object of the invention is to provide a new and improved rotary striping wheel paint striper which,` while being adapted to overcome the aforesaid ditliculty experienced in the use of prior rotary striping Wheel paint stripers is likewise adapted for general paint striping use.

Other objects will appear hereinafter.

Fig. 9 is an exploded view, partly in section, showing the various parts embodied in the new rotary striping wheel paint striper tool. l

A preferred embodiment of the new rotary striping wheel paint striper tool is illustrated in the drawings' where it is generally indicated at l0, and comprises a paint storage container 0r receptacle in the form of ha bottle 11, which may bemade of glass, resinous plastic, or other material, and which has a reduced externally threaded neck portion 23` which is adapted to be threaded into the internally threaded portion' of a frusto-conically shaped coupling member 13. rlhe new rotary striping wheel paint striping tool 10 also includes a striping wheel and striping wheel holder jaw assembly 14 which includes a pair of rotary striping wheel holder jaws 15, each'of which includes a generally hemispherical swivel head portion 16, and a depending lower portion 17, from which a` paint-supporting depending flange 18 extends.

The rotary striping wheel holder jaws 15 are held to` gether in assembled relationship by a pintle 19 which extends through and is mounted on the depending anges or extensions 18 and a pair of rotary striping wheels 20 are mounted on the pintle 19 in assembled side by sid'e relationship, each of the rotary stripingwheels 20 having a knurled peripheral surface, as shown.

Each of the generally hemispherical shaped swivel head portions 16 has a centrally arranged recessed groove 21 formed therein on its inner `surface and the lower portion. i7 of each wheel-holding jaw 13 has a recessed groove 22 formed therein on its inner surface, and these grooves 2l and 22 cooperate to form a central longitudinal passage through the striping wheel and holder jaw assembly when the parts are arranged in assembled position of use'l so as to conduct paint or like striping material from .the

Patented Apr. 16,

3 storage container 11 onto the Vperipheral surface of the rotary striping wheels 20.

A gasket 24 is arranged in the coupling member 13 between Athe-lower'or 'inner edge of the neck `23 of the storage container v1.1 and the swivel head portions 16 of the ,striping wheel holder jaws 15, and this gasket 24 has a centrally arranged opening 25 formed therein.

Aguide arm member 26 may be adjustably mounted in a.boss.27 which is attached to one side of the coupling member '13, and the guide arm 27 may be clamped in position of ,use by `a set screw 2S which .is mounted in the boss 27.

In the use of the new .rotary wheel striping tool, the jaw holder members may be arranged in assembled side by side ,complementary relationship, and on rthe pintle 1`9,jas shown in Fig. 2, and the parts, so arranged, may 4be extended Vthrough the frusto-conical shaped couplingjr'nember 13 vfrom the larger upper end portion thereof into the lower end portion thereof so that the Swivlheadpor'tions 16 thereof will bear against the inner wallsu'rface of the said frusto-conical shaped coupling 13. When the parts are so arranged the grooves 21 and 22 cooperate to form a central bore or passage through the striping wheel and striping wheel holder jaw assembly with'the outlet o'f'this passage opening above the serrated orknurled surfaces of the striping wheels 20 (Figs. 7 and 9).

The gasket 24 may then be arranged in position of use above the swivel lhead portion 16 of the holder jaw members 1'5, whereupon the storage container- 11 may be filled with suitable paint or other like surface-striping material. The coupling member 13, with assembled striping head assembly 14, is thenscrewed onto the externally threaded portion 23 of the storage container bottle 11,-whereupon the parts will be arranged in assembled position, as shown in Fig. 7 of the drawings.

In the use of the new rotary wheel striping tool, the same'may be employed in the manner illustrated in the Coombs Patents Nos. 2,122,858 and 2,582,861 to stripe paint-or 'other surface-striping material, in the form of lines, or otherwise, such, for example, as a piece of furniture-or-'othermaterials, and such a use of the new striping to'olfis 'illustrated Iin Fig. l of the drawings. When so arranged, the paint or like surface-striping material from the-'storagecontainer or receptacle 11 will flow, by gravity, downwardly through the externally threaded neck portion-23 of the storage container il, through the central opening 125 in the gasket 2d and into the central bore ori passage '2l-22 formed in the striping wheel and striping :wheel holder jaw assembly 2A by the cooperation of thergrooves 21 and 22, and thence onto the external surfaces ,of the serrated striping wheel Ztl, by which the paint or other `surface-striping material is conveyed onto the surface or work 3% over which the new striping wheel tool Amay be moved, as shown inFig. l.

As hereinbefore pointed out, it happens that in the use of rotary paint striping tools of the character shown in the aforesaid patents, it is desirable to stripe upon a vertical wall or like surface, such as upon a vertical surface of. a -piece of furniture, or the like, and the present inventionhas the advantage over lthe striping wheel tools shown in .theaforesaid patents which enables this to v be done in the manner illustrated inFig. 8 of the drawings. rihus, as will 'be seen by reference to Fig. 8, in order .to provide a paint stripe or the like, on the vertical surface 29, such as upona vertical wall or the vertical surfacerof apiece of furniture or the like, this may be accomplished .by slightly loosening or partially unscrewtheexternally threaded neck portion 23 of the storage containeror receptacle 11 inthe coupling member 'i3 and then moving the swivel head portion 1.6 of the striping wheel holder jaws 15 in the coupling member 13 so that the striping wheel holder jaws and striping wheel assembly 1-4 are 'arranged at an acute anglerelative to the .axes of the s'tora-gecontaineril and coupling member 13, as

'shown yin Fig. '3. The new striping tool, 'with the parts thus arranged, may then be arranged in the position in which they are shown in Fig. 8, with the striping wheel jaw holder and striping wheel assembly M- arranged in a generally horizontal position relative to the vertical surface 29 to be striped and with the coupling member 13 and the storage container l1 arranged at an acute angle relative to the generally `horizontal axes of the striping wheel holder jaw and striping wheel assembly 14, as shown in Fig. 8.

yWhen the parts are thus arranged in the manner shown in Fig. 8, the paint or like surface-striping material will tiow by gravity from the storage container 11, through the externally threaded neck portion 23 thereof, through the central aperture 25 in the gasket 24, through the central passage Zit-ZZ in the striping wheel holder jaws 15 and thence, by gravity, `onto the serrated peripheral surfaces of the striping wheels Ztl, which may be moved over the vertical surface 29 to complete the striping operation.

It will be noted that when the parts -of `the new striping wheel tool are arranged as in Eig. 8, the force of gravity allows the paint or like striping material to ow from the storage container, and through the passage 23-25* 2122 onto the knurled lor peripheral surface of the striping wheels 20, whereas if the storage container 11 was arranged on the same general axes as the striping wheel holder jaw and striping wheel assembly 14 the paint or like striping material in the storage container would not flow readily `or adequately from the storage container ...l through the passage 23-25-21-22 onto the peripheral surfaces of the striping wheels 2@ in -a manner sucient to perform satisfactory paint striping.

lt will also be noted that the parts of the new striping tool may be readily disassembled for cleaning of the parts aftereach usev thereof or for repair, as and when desired.

It will thus be lseen from the foregoing description, considered in conjunction with the accompanying drawings,-that the present invention provides a new and irnproved rotary striping wheel paint striping tool having the desirable advantages and characteristics, and accomplishing its intended object, including those hereinbefore pointed out, and others which are inherent in the invention.
