A CORPORATION OF WASHINGTON.

VALVE FOR FGUNTAIN BRUSHES.

Application filed February 19, 1925. Serial No. 10,175.

My invention relates to fountain brushes. The object of my invention is to provide a superior type of construction for fountain brushes such that its cheapness of manufacture is added to, while at the same time securing advantages in the operation thereof.

The brush which isthe subject of my-in: vention contains a hollow handle which serves as a reservoir for the fluid to be applied, a brush or head which is connected with the reservoir tl rough a tubular stem, and a valve which controls the application of the fluid through the brush.

In the accompanying drawings 1 have shown a preferred type of construction for my invention.

Figure 1 is pleted brush.

Figure 2 is a longitudinal section through that end of the handle to which the stem of the brush is connected, showing the valve and its controlling means.

The handle section 1 is in the form or" a tube, provided with means as a cap 10 at one end, by which the liquid to be used may be supplied thereto. The brush head 2 consists of a base 22 holding suitable bristles 21. ase 22 is axially bored to provide a fluid discharge communicating with the tubular stem The other end of this tube enters one end of the tubular handle 1. @ne end of the tubular handle 1 is provided with reduced diameter section 11. This is sufficiently larger than the stem 3 of the head as to provide a chamber of ample size to contain a spring a, by the action of which the fluid feeding and controlling valve is normally held in closed position.

This valve may consist of a short screw having a conical head 5, the stem of which screws into the inner end of the brush stem 8. The differing diameters of the sections 1 and 11 of the handle are joined by a tapering section 12 At the same point the handle has therein a sleeve 6 which is preferably made as a piece of spun or stamped metal which has a conical surface 60 complemental to and cooperating with the coned under surface of the valve 5 to form a seat therefor. One end of this sleeve is also flanged back, forming a section 61 which is forced into close contact with the base of the coned section 12 of the handle. To then hold the sleeve in place the tube forming an exterior view of the comthe handle maybe slightly rolled or crimped inward, as shown at 13.

Guides for the brush stem 8 are formed by twowashers 7 and 70, one located at the outer end of the reduced section 11 of the handle and secured in place by a tight fit 1n the reduced section 11. The other is similarly secured in place at the point where the section lljoins the taperingsection 12. The sleeve 15 has its major portion surrounding the extreme inner end of the tube 3 which forms the stem of the brush. It is sufiiciently larger than this to form an annular channel or chamber located adjacent to the valve head 5. The tubular brush stem 3 ispro vided with ports as 30, located between the stem portion of the screw which forms the valve 5 and the guide washer 70. For the purpose of making a reasonably tight joint surrounding the stem 3, a washer as 71 of compressible material such as felt, is inserted between the metal washer 70 and the adjacent end of the sleeve 6.

It is evident that if the stem 3 of the brush head he forced backward or farther into the tubular handle, the liquid will be permitted to flow into the annular chamber 31 between the stem 3 and the sleeve 6, and Will then be permitted to flow through the ports 80 into the tubular stem 3, and thence to the head 2.

The reduced end 11 of the tubular handle is provided with slots 14: through which passes a bolt 32. This bolt forms a stop or abutment for one end of the spring 4, the other abutment being the metal washer 70. This spring normally holds the valve head 5 upon its seat 60 and prevents outflow of the fluid contained in the hollow handle. The valve may be moved away from its seat to permit flow of the fluid either by backward pressure caused by pressing the head upon some fixed object, or by engaging the head of the bolt 32 with the thumb and forcing the stem backwards.

A fountain brush constructed as described may be manufactured cheaply. It is also efficient and convenient in its operation. It is necessary to move the stem 3 inwardly only a short distance to open the valve to permit flow of the fluidto the head, yet the type of valve employed forms a sure and certain closure. It is also one which may be cheap- 1y manufactured and conveniently obtained.

A brush of this type is adaptable to a great variety of uses. It may be used as a brush for lettering or as a stencil brush. It may also be used to supply blacking or shoe polish as used. In fact there are a great variety of uses to which it may be conveniently put.

What I claim as my invention is 1. A valve comprising a tubular member, a hollow stem, mounted to have a limited reciprocation with relation to the tubular memher, a sleeve secured within the tubular member and surrounding the inner end of the stem, said sleeve and stem having diameters adapted to form an annular space between them, a closure for the outer end of said annular space, the inner end of the sleeve having an inwardly facing valve seating surface and outward extensions therefrom joining with the tubular member, and a valve head carried by the stem and seating on said valve seat, the stem having exit ports in its walls located outward of the valve head and within the extent of the sleeve.

2. A valve comprising a tubular member, a hollow stem mounted to have a limited axial movement with relation to said tubular member, a sleeve surrounding said stem and within the tubular member, said sleeve having an inner diameter greater than the outer diameter of the stem to form an annular channel between them, a closure for the outer end of said channel, the inner end of the sleeve having an inwardly facing valve seat and an extension forming a sealing connection with the tubular member, a valve carried by the stem and cooperating with said seat, the stem having exit ports located outwardly of the valve and within the annular channel, and a spring hold the valve closed.
