1 Claim. (Ci. -13

The present invention relates generally to fountain stencil brushes, and more particularly to the body member of a fountain stencil brush which is formed to comfortably receive the fingers of a user and to reduce to a minimum the possibilities of fingers slipping from place during use of the brush.

In brief, the present novel fountain stencil brush body includes a flange and neck which are formed with parallel opposed merging grooves, each pair of which receives a finger of the hand of the user.

Therefore, an object of the present invention is to provide a novel fountain stencil brush body or housing which incorporates finger grooves which reduce finger slippage and which render gripping more comfortable.

Another object is to provide a novel fountain stencil brush body which incorporates a flange and a valve neck which are contoured at opposite sides to form parallel finger grooves.

Another object is to provide a novel fountain stencil brush body which is formed to render stenciling use of the brush of which it forms a part easier on the fingers and readily grasped against slippage.

The foregoing and other objects and advantages are apparent from the following description taken with the accompanying drawing, in which:

Fig. 1 is a side elevational view of a fountain brush incorporating a novel body formed in accordance with the teachings of the present invention, the fingers of a hand being shown grasping the brush;

Fig. 2 is a side elevational view of the brush shown in Fig. 1 rotated 90 to the right; and

Fig. 3 is a horizontal cross-sectional view on substantially the line 33 of Fig. 1.

Referring to the drawing more particularly by reference numerals, 10 indicates generally a fountain stencil brush which incorporates a body 12 including the principles of the present invention. The brush 10 also includes the usual barrel or ink reservoir 14 and a bristle assemblage 16, both of which threadedly engage the body 12 in the well known manner, such as is illustrated in the Marsh et al., Patent No. 2,236,625.

The body 12 includes a hexagonal flange 18 and a valve neck 20, the latter being of elongated form, as is clearly shown in Fig. 3. The valve neck 20 encloses a valve, such as that illustrated in the above-mentioned patent, which is controlled by a push button 22.

The flange 18 includes two parallel grooves or channels 24 which merge with parallel grooves 26 formed in the sides of the neck 20. A radius of three-eighths of an inch for the

grooves

24 and 26 has been determined as an average acceptable radius, where the

grooves

24 and 26 are formed as true arcs in cross section. Manifestly, other radii could be employed, and it is not necessary that Cit Patented Jan. 3, 1956 true arcs be used. The

grooves

24 and 26 parallel the axis of reciprocation of the push button 22 in order to dispose the fingers and the thumb in proper grasping relation and the latter for ready push button manipulation.

In Figs. 1 and 2, a hand 28 is shown with the fingers grasping the brush 10. The middle finger 30 and the ringfinger 32 are disposed in the merging

grooves

24, 26. The thumb 34 is disposed for ready manipulation of the push button 22, it being understood that fountain stencil brushes 10 do not require the valve actuated by the push button 22 to be open continuously during use of the brush 1.0.

The grooves 24 reduce to a substantial degree the slippage of fingers from the flange 18. The merging grooves 26 combine with the grooves 24 to provide room for the fingers and to render grasping the brush 10 more comfortable, whether the grip shown in the drawing is employed or any one of many other grips is used.

It is manifest that there has been provided a fountain stencil brush body construction which fulfills the objects and advantages sought therefor.

It is to be understood that the foregoing description and the accompanying drawing have been given by way of illustration and example. It is also to be understood that changes in form of elements, rearrangement of parts, and substitution of equivalent elements, which will be obvious to those skilled in the art, are contemplated as within the scope of the present invention which is limited only by the claim which follows.

What is claimed is:

A fountain brush comprising a neck bounded at its top by the lower end of a brush barrel reservoir for marking fluid having a bottom extending laterally beyond said neck, said neck being bounded at its bottom by a flange of a brush body extending laterally beyond the neck, said neck having two straight parallel side walls with grooves therein parallel to the junction of the side Walls with said flange, said neck having conduit means between the reservoir and the brush body, said flange being provided with grooves parallel to said side walls, and each of said neck grooves merging with one of the grooves in said flange to form a coextensive smooth rounded surface for receiving comfortably the tip of an operators finger, said coextensive smooth rounded surface being arcuate in cross section and of substantially the same radius of curvature, and a valve operating member in said neck between the grooves at one end between the side walls thereof for controlling flow through said conduit means, whereby the barrel of said brush may be grasped by an operators hand between the thumb and the index finger with the operators fingers being conveniently received in said grooves on opposite sides of the neck in a position such that the operators thumb may easily operate said valve without changing the position of said fingers.
