April s, 1952 E. S. GARVEY VALVE FOR FOUNTAIN STENCII.. BRUSHES Filed July 22, 1949 Patented Apr. 8, 1952 AUNITED STATES PATENT GFFICE VALVE FOR FOUNTAIN STENCIL BRUSHES Edward S. Garvey, Clayton, Mo.

Application July 22, 1949", Serial No. 106,149

My invention relates to fountain applicators for dispensing stenciling iiuid from a reservoir handle to a stenciling medium, and, more particularly to a nger pressure actuated valve for controlling the admission of predetermined amounts of uid from the reservoir to the interior of the stenciling medium, and for positively stopping the flow of fluid when the pressure is removed.

The primary object of the invention consists in providing a fluid control valve including a packing element therefor that may be replaced by the user of the applicator, thus obviating the necessity of sending the applicator back to the factory for replacement of the packing, which is the present practice, thus avoiding inconvenience to the user of the applicator due to the time lost in having the packing factory replaced.

A further object of the invention consists in providing a fluid control valve that will positively prevent bleeding of fluid from the reservoir to the stenciling medium, thus preventing the control means from becoming fluid hooded and thereby avoiding uid being transferred from around. the control means to the lingers of the applicator user.

Another object of the invention consists in providing a fountain applicator that possesses the foregoing features, which is simple in construction and in use, inexpensive in cost of manufacture, and which embodies a minimum number of parts.

The above objects of the invention are achieved, and highly eincient results attained, as is evident from a consideration of the following descriptionl and claims and from the illustration of the invention in the drawings. l

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

In the accompanying drawings, forming a part of this application, and in which like numerals are employed to designate like parts throughout the same, y

Fig. 1 is a longitudinal sectional view of a fountain applicator embodying the features of a Dreferred embodiment of the invention.

Fig. 2 is a top plan View of the fountain applicater.

Fig. 3 is a transverse sectional view taken through the valve containing head portion .of the reservoir and handle.

Fig. 4 is a fragmentary view showing the fluid 2 fluid from the reservoir handle to the interior of the stenciling brush.

Fig. 5 is a view of the fluid control means with the parts thereof shown in extended positions.

The fountain applicator herein disclosed is used more particularly as a stenciling brush, or marker.

, outer end of the body portion I 0 is closed by means f of a suitabler closure member, or cap II which is detachably secured thereto so that the reservoir may be easily filled with the stenciling iiuid designated I2. A suitable gasket II' is carried with` in the cap to engage the end face of the body portion I 0 to provide a leak proof joint therei between. The cap Il is provided with a suitable bail-like member I3 which is shown as hingedly connected to the cap sc that the applicator may be hung, or suspended from a nail, hook or other suitable support when the applicator is not in use.

The tubular body portion I0 opposite the cap supporting end includes a head-like portion I4 having an end socket I5 for detachable connection with the head I6 of a suitable stenciling, or marking brush made from suitable bristles I1. The head I6 of the brush is provided with a central port I8 to feed fluid to the inside of the brush, and there is a washer-like gasket I9 disposed between the bottom of the socket I5 and the head I8 of the brush to provide a leak proof joint between the wall of the socket I5 and the wall of the brush head I6. The brush head I6 is shown as having screw-threaded connection with the wall of the socket I5.

The head-like portion I4 is provided with a transverse bore to provide a socket 20 open to one side of the head portion only, and the head portion I4 is also provided in the wall of the transversesocket 20 with opposed ports 2l and 22 centrally of the longitudinal axis of the reservoir and handle portion I0, as clearly shown in Figs. 1 and 3. The port 2| is designed to carry fluid from the reservoir to a fluid control valve. later described. and after passing through the valve, the port 22v delivers the fluid to the brush' head port t8 to be delivered to the interior of the stencilingbrush, or marker, as is clearly apparent from. Figs. 1 and 4'.

control means depressed to allow admission of 68% The fluid control valve above referred to and its parts illustrated in extended positions in Fig. 5, consists of a cylindrical valve body 23 open at both ends and provided at its one end with a flange 24. The valve body 23 has a press fit with the transverse bore, or socket 2|] so as to lie between the aligned fluid ports 2| and 22, as clearly shown in Fig. 1. The flange 24 lies in a recess 25 in the head portion I4 surrounding the open end of the transverse bore, or socket 20. The valve body 23 is sealed within the bore, or socket 26, thus preventing fluid leakage between the head |4 and the valve body 23.

'I'he end of the valve body 23 opposite the flange 24 is provided with an interior truncated cone shaped valve seat '216 and a wall recess 21 adapted to receive a pin 28 carried by a cone shaped valve member 29 adapted to normally engage the valve seat 26 so as to prevent rotation of the valve member 29 relative to the valve body 23 yet allow limited longitudinal sliding movement of the valve member 29 when it is desired to open the valve, as shown in Fig. 4 from its closed position, as shown in Fig. l.

The interior wall of the valve body 23 is also provided with a truncated cone shaped packing seat 30 adjacent and opposed to the valve seat 26 to accommodate the seating of a suitable packing member 3| having a central opening 32 to receive the passage of a valve stem 33 which is screw-threaded, or otherwise detachably connected at its inner end with the inner end of the valve member 29 so that the valve members may be disconnected to replace a worn packing member 3|. Both

seats

26 and 30 are arranged intermediate the ends of the valve body 23. The valve stem 33 is provided at its outer end with a head 34 having a sliding fit with the inner wall of the valve body 23 and a portion of which head normally projects beyond the flanged end of the valve body so as to be actuated by a finger of the operator of the fountain applicator.

There is a suitable coiled spring 35 disposed between a Washer 36 which engages the packing member 3| and the head 34 of the valve stem and the spring encircles the valve so as to exert pressure against the packing member 3| and against the head 34 ofthe valve stem to move the valve member to closed position when finger pressure is3 removed from the head 34 of the valve stem 3 'I'he valve body 23 is provided in the valve seat wall thereof with

opposed fluid ports

31 and 38 which register with the fluid ports 2| and 22, respectively, so that fluid may be delivered from port 2| to the port 22 and then to port |8 to feed the brush bristles Il, when the valve stem has been forced inwardly by finger pressure on the projection head portion 34 of the valve stem. When the cone shaped valve member 29 has been moved away from its cone shaped valve seat 26 within the valve body, there will be provided an annular fluid passage 39 around the smaller end of the valve member 29 which communicates with the

valve body ports

31 and 38, thus allowing controlled amounts of fluid to be delivered from the fluid reservoir to the interior of the stenciling brush, or marker, as will be clearly apparent from Fig. 4 of the drawing. When finger pressure is removed from the'valve stem head 34, the spring 35 will close thevalve and stop the ow of fluid from the reservoir to the interior of the brush, as will be apparent from Fig. 1. l

The outer face of the valve stem head 34` is provided with a screw driver slot 40 soA that with the aid of a screw driver, the operator may disconnect the valve stem 33 from the cone shaped valve member 29 and remove the valve stem I3 and spring 35 from within the valve body 23. After such removal of parts, the washer 36 and a. worn packing member 3| may be fished out of the valve body 23 and a new packing member 3| placed within the valve body 23, thus obviating the necessity of having to send the applicator back to the factory Ifor the mere replacement of a work packing member 3|. After a new packing 3| has been positioned within the valve body 23, the washer 36 and spring 35 are placed back in position and the valve stem is then screwthreadedly connected with the cone shaped valve member by means of a screw driver. It is clearly apparent that the cone shaped valve member 29 'cannot rotate or turn in the valve body when disconnecting the valve stem therefrom, or connecting it therewith, due to the pin and recess connection between the cone shaped valve member 29 and the valve body 23.

The many advantages of the herein described invention will readily suggest themselves to those skilled in the art to which it appertains.

It is to be understood that the form of my invention, herewith shown and described, is to be taken as a preferred example of the same. and that various changes in the shape, size, materials and arrangement of the parts may be resorted to without departing from the spirit of my invention, or the scope of the subjoined claims.
