FOUNTAIN .BRUSH Filed April l2, 1945 3f 1 nllglllll um WAH-0N C. MA1/as@ Patented Sept. 5, 1950 FOUNTAIN BRUSH Walton C. Marsh, Belleville, Ill., assigner to Marsh Stencil Machine Company, Belleville, Ill., a corporation of Illinois Application April 12, 1945, Serial No. 587,873

1 Claim. l The present invention relates to a fountain brush.

It is an object ofthe invention to provide a brush having a particularly comfortable and convenient grip, thus eliminating strain on the hand and wrist. A further object is to provide a brush designed for convenient use and handling in a number of different positions as when steneiling sides as well as tops of cartons.

It is a further object to provide a fountain brush upon which the operator can apply pressure with his hand, rather than rwith his fingers, and one which will enable the operator to keep the bristle tips applied squarely against the stencil.

A further object is to provide a fountain brush in which the inking button is conveniently available to the finger, thumb, or heel of the hand, and to provide a. combination of hiandle arrangement and button arrangement wherein only a minimum amount of button movement is required.

More particularly, it is an object of the invention to provide a fountain brush having a reservoir handle in the form of an elongated, hollow member disposed transversely with respect to the axis of the brush portion, with an easy acting valve in a neck between the reservoir and the brush.

In the drawings:

Fig. 1 is a side elevation of the device;

Fig. 2 is an end elevation, taken from the right of Fig. 1;

Fig. 3 is a vertical section on the line 3-3 of Fig. 1;

Fig. 4 is a horizontal section through the axis of the valve, taken on the line `4---4 of Fig. 2 and showing the valve in closed position; and

Fig. 5 is a view of the valve similar to that in Fig. 3, but with the valve open.

The brush includes a, handle-reservoir part I0, la neck II, and a brush I2. The handle Ill is here shown as a hollow cylinder having an end closure I3 which may be removed for pouring ink into the handle. Of course, the cap I3 can be put at a location other than the end of the handle, but the latter is a very convenient disposition of this element.

Midway between the ends of the handle I0 and projecting triansversely therefrom is the neck Il which contains a valve mechanism -generally indicated at I4. The neck communicates with the interior of the handle I0 through a port I5 and a funnel-shaped opening I6 terminating in a transverse bore Il. Below the bore I'I is a Vertical 2 opening I8 in alignment with the bottom of the opening I6. The opening I8 opens into the middle of a brush I2.

The transverse opening I I opens through to one edge wall of the neck portion II. Within'it is disposed a sleeve 20 of brass or the like, this sleeve having two transverse ports forming continuations of the openings I6 and I8.

The valve unit, generally indicated at I4, is threaded into the opening I'I. This valve unit includes an outer sleeve 22 having an outer shoulder followed by a threaded portion, and the latter followed by a reduced part 25 that slides into the sleeve 20 with a liquid-sealing fit, and that has a squared-ofi end. When the sleeve 22 isV threaded into the neck portion, the squared-oit end of the projection 25 is disposed beyond the edge of the opening I6, substantially as shown in Figs. 4 and 5.

The sleeve 22 is hollow Iand receives a valve stem 26 having a slide valve head 21 secured thereto. The head is cylindrical and has a squared-off end adapted to engage the correspondngly shaped end of the projection 25, in sealing relationship. The stem 26 extends through the projection 25 and into a hollowedout portion 28 of the member 22, where it is surrounded by a. coil spring 29 and packing washer means 30. An operating button 3l is threaded onto the outer end of the stem 2B and acts as one abutment for the spring 29. The spring normally holds the valve plug outward.

Operation It will be seen that this brush can be grasped by the hand rwith the brush bristles projecting in a radial direction from the fist around the handle. The brush may project at an angle comfortable for the work being done and for the particular operator. The button 3| is convenient to the thumb or to the heel of the hand, or, when the brush is turned around, to a nger. Thus the brush may be used to stencil horizontal surfaces or vertical surfaces without any twisting of the arm muscles.

Also a minimum amount of button operation is required. The fact that the end of the projection 25 extends beyond the left end of the opening in Fig. 4 causes the movement of the valve away from the projection to provide a maximum opening with minimum movement. It is apparent that were the valve to move from the most leftward point in the edge of the opening in Fig. 4, half-way to the center of the opening, the stroke would provide a much smaller port When the valve is opened, ink from the handle i I0 flows downward through the openings i5 and IG, past the valve, and through the opening i8 to the brush l2. The valve, when closed, seals off the ink supply and will not'leak.

When not in use, the brush can beplaoed `in the upright position with the bristles resting on the table, or it can be laid flat.

What is claimed is:

A fountain brush including an elongated handle grip portion having a liquid-containing well ytherein, a neck portion extending substantially radially from said -g-rip portion, a liquid applicator on the neck outward from the grip portion, ja passage `througi'ifti'ie meek from the well to the -app'lieaton a control valve inthe passage, said passage being simular, and said control valve ino'luding -a xed member having its axis located transversely of the axis of .the passage and having a transverse surface intersecting the passage at approximately half-way outward from the center of the passage, the control valve also having va reciprocating slide element disposed to -sI-ide axially toward and from the xed member S'rntersecting the passage beyond the xed member at a point substantially halfway between the center of the passage and the inner tangential edge thereof as an inner extreme position of movement and having a surface adapted to engage the transverse surface of the fixed member in a liquid-sealing relationship in the outer extreme position of movement thereof, means yieldingly holding the slidable member with its surface thus against the fixed member, whereby a minimum of movement of said reciprocating slide element eiects a maximum amount of liquid ow, anda push button operatively associated with said slide element for manual movement thereof inward-ly of said neck and towards said passage to `open the same, said push button being readily accessble to the heel of the palm of the hand or to the 'lingers of a user, a minimum of movement of said slide element through actuation by said ypush button effecting a maximum amount of liquid flow.
