LEON WILLIAM SIMMONS, 0F LOS ANGELES, CALIFORNIA.

FOUNTAIN MARKING-BRUSH.

To all whom t may concern l Be it known that I, LEON W. SIMMONS, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Fountain Marking-Brushes, of which the following is a specification.

My invention relates to fountain marking brushes for use in sign painting, card writing, marking by stenciling and the like.

An important object of my invention is the provision of a fountain marking brush which can be readily filled and operated without the detachment of any of the parts.

A further object of my invention is the provision-of a brush embodying means for carrying a marking fluid in the structure of the brush itself, thus doing away with inconveniences incident to the carrying of a separate container for the marking fluid.

A further object is the provision of a fountain brush embodying means forv regulating a uniform and steady flow of kthe marking fiuid' to the brush element.

A further object is to provide a device as above described which will be inexpensive to manufacture; durable; efficient in operation; and exacting a minimum of wear upon any of its parts.

Other objects and advantages of the invention will be apparent during the course of the following description.

F ig. 6 is a perspective view of the plunger element.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the letter A desig nates a tubular casing, adapted to act a primary container for a marking fluid and having a brush receiving element or hollow cap B mounted upon an extremity thereof and acting as a secondary fluid container. A piston rod C, and piston or plunger element D are reciprocably mounted in the tubular casing A for the purpose of effecting the entrance of the liquid into the container and controlling the iiow ceiving element B.

The brush receiving element B is preferably formed in the shape of a hollow cap, being detachably connected by an upwardly into the brush re-v extending annular flange 11 to an'entremity v of the tubular casing A as by screw threads 11, and is preferably constructed in two sections, 12 and 13. Section 12 is the Section detachably connected to the tubular casing and is provided with a passageway 14, forming means of communication between the tubular casing A and the opening 15 in the hollow cap B. Section 18 is hollow and preferably tapered, and is detachably connected to section 12 as by screw threads 16, the point of juncture of sections 12 and 13 being the point of greatest area of opening in the hollow taperingl portion 13. `The opposite or converging end of section 18 being provided internally with screw threads 18, adapted to receive an externally screw threaded plug 19. f

The plug 19 is tapered to conform with the tapering of the hollow portion 13, a slot 20 Vbeing provided therein to receive a screw driver or other tool for readily seating the plug within the section 13. Bristles 21 depending froin an end of the plug 19, and suitably mounted therein, have `communication with the opening 15` of cap B, and the interior of the tubular casing A by means of slots 22 in the plug 19.

-The piston rod C is reciprocably mounted within the tubular casing A, the upper eX i projections 34 of the hooked pins tremity projecting from the tubular casing and being provided with a head Screw threads 24 are provided upon the piston rod C immediately adjacent the head 23 and adapted for engagement with a screw threaded aperture 25 in a cap 26, the cap 26 being detachably connected to an extremity of the tubular casing A as by screw threads 27. The lower extremity of the piston rod C or that portion depending within the tubular casing A is provided with a conical enlarged head 29, adapted to seat within the passageway lll of the hollow cap B to regu-V late communication between the tubular casing A and the hollow cap B, upon rotation of the piston rod threads 24, within the screw threaded aperture 25. The conical head 29 is provided with a pin 30, laterally projecting therethrough and terminating short of the internal walls of the casing A.

The pistonD is preferably constructed of resilient or flexible material, and is provided with hooked pins 32'detachablyconnected thereto as by nuts 83, the projecting portions 34 of the hooks 32 being so arranged and depended from the piston D as to be readily engaged and disengaged by the pin 30. Because of the flexibility of the piston jl), washers 35 and projecting portions 36 upon the pins 32 are provided to form a more effective construction. In operation it is obvious that asvthe screw threaded portion 24 of the piston rod is disengagedfrom the screw threaded aperture 25 the piston rod will be free to reciprocate within the tubular casing A', and independent of the reciprocation of the piston D. However as the piston rod is drawn upward till the conical head 29 fits within a depression 37 in the piston, and the piston rod is rotated, the laterally projecting pin 30 will strike the hooked pins 32, and upon downwardor a reciproeatory movement the piston will be reciprocated in unison with the piston rod, by means of the lateral pin 30 engaging the In Y filling the tubular casing A with a marking fluid the hollow cap B is .inserted into the fluid, the piston D is then drawn from the bottom to the top extremity of the casing and the suction thus created within the cas ing will draw the fluid throughthe slots 22 into the casing A. Should the fluid be of such consistency as to require, regulation `of flow upon the brush, or it be desired to use only a limited amount, that amount can be regulated -by means` of rotating the screw threaded portion 24 of the pistony rod C in the aperture 25, this opera-tion havingrithe effect of regulating communicaton between thetubular casing lO and the hollow cap 11.`

It is to be understood that the form of myinvention herewith 'shown and described is to be taken asapreferred example ofthe same, for it may be desired to do away with the regulation secured by the conical head 29 seating within the passage way 14, and have the marking fluid feed directly upon the bristles 21. Various other changes in the shape, size and arrangement of parts may be desired and resorted to without departing from the spirit of my invention or the lscope of the subjoined claims.

I claimt l. In a fountain marking brush the combinationr of a tubular casing, a brush, a piston reciprocatingly mounted within said casing, a. piston ro reciprocatingly carried by said casing, and means detachably connecting said piston and piston rod whereby the latter may be reciprocated independently of the former.
