AUTOMATIC DISPENSER Original No. 1,516,850, dated November 25, 1924, Serial No. 664,736, filed September 25, 1923. Application for reissue filed September 24, 1926.

This invention relates to improvements in dis ensers and the like.

ne of the principal objects of the invention is to provide a dispenser which is adapt ed to operate automatically in that the valve may be opened by positioning a receptacle under the mouth of the dispenser and thus engage the valve operating means to open the valve and discharge the fluid and in that upon the removal of the receptacle, the valve is automatically closed.

Another object is the provision of a simple and eflicient valve actuation mechanism including a spring operated and free from any complicated system of levers or the like.

A further object is the provision of a dispenser which operates upon the placement of a receptacle upon a fiat platformwith a slight downward pressure applied thereon.

With the foregoing and other objects in view the invention consists in the combination of parts and in the details of construction hereinafter described, a preferred embodiment thereof being illustrated in the accompanying drawings, in'which Fig. 1 is a view in vertical section through the dispenser showing the sleeve valve in closed position and the dispenser in inopera tive position;

Fi 2 is a view in vertical section through the ispenser showing the sleeve valve in open position and the dispenser in operative position;

Fig. 3 is a side elevation with parts in sec tion of a modification of the dispenser.

Fig. 4 is a side elevation of another modification of the dispenser showing the pipe provided with a swivel joint;

Fig. 5 is a plan view of the top platesecured to the valve body;

Fi 6 is a view in vertical section through the ispensing pipe showing a valve of the type illustrated in Fig. 3 located in the lower portion of the pipe.

Referring more in detail to the drawings, the body 1 is made hollow to receive the cylindrical sleeve valve 2 so mounted therein as to be slidable vertically. The sleeve valve 2 is partly hollow and is provided with but two ports, 4 an inlet, and 5 an outlet, both being circular and adapted to register with those of the inlet nipple 6 and outlet nipple 7, respectively.

The valve 2 is provided with a valve stem Serial No. 137,618.

3 which protrudes through a suitable opening in the upper part of the body 1. Secured to and resting on this stem 3 is a substantially flat platform 10 adapted to receive any suitable receptacle 11 to be filled. In the lower portion of the hollow body 1 is arranged a compression coil spring 12 adapted to exert upward pressure on the valve 2, and normally retain the latter in closedposition. A suitably curved pipe 17 is attached to the outlet nipple 7 and is provided with a discharge opening 9.

Fig. 1 shows the spring 12 in extended position thus forcing the valve in closed position. As shown in Fig. 2, when downward pressure is applied on the platform 10 the valve 2 is forced downwardly against the action of the spring 12, and the inlet port 4 registers with that of the inlet nipple 6, while the outlet port 5 registers with that of the outlet nipple 7, thus presenting a continuous passageway for the fluid introduced through the nipple 6 to be discharged into the receptacle 11.

Upon the withdrawal of the downward pressure upon the platform 10, the compression spring forces the valve 2 upwardly and the ports A and 5 out of registration with those of the nipples 6 and 7, respectively, thus closing the valve and stopping the flow of the fluid as shown in Fig. 1.

As shown in Fig. 3 a modified form of my invention comprises a valve casing 22 extending through the upper horizontal portion of the pipe 17, the casing "having ports 25 in register with the pipe 17 and adapted to register with the recess 24 in the reciprocatory valve 23. The arm 18 is provided with an upright extension 18 extending through the lower portion of casing 22 and connected to the valve.

lVhen the platform 10 is pressed downwardly the downward motion is transmitted through the arm- 18 and its extension 18 to the valve 23 against the action of a compression coil spring 26 between the valve 23 and the bottom of the casing 22. This action brings the recess 24 and ports 25 into registration, opening the valve and permitting the discharge of the fluid. Upon the release of the downward pressure on the platform 10, the spring 26 automatically forces the valve upwardly into closed posi= tlfillb shown in Fig. i the upper portion of the pipe 17' may be provided with a swivel oint at 230 in order that the discharge end of the pipe may be swung into differentpositions such as indicated in dotted lines for the purpose of filling larger receptacles not adaptable to be placed on the platform 10. Having so manipulated the device it is only necessary to apply pressure with the hand on the platform 10 to cause the liquic to be dispensed.

In all of the modifications presented the stem for supporting the platform, shown in Figs. 1, 2 and 4, is of a square crosssection so as to fit the square aperture 29 in the top plate 2. fastened on the body 1 by the screws 28, as shown in detail in Fig. 5.

As shown in Fig. 6 the valve and its actuation mechanism of the type disclosed in Fig. 3 may be arranged in the lower portion of the dispensing pipe.

Having thus described my invention, I claim 1. A fluid dispenser comprising a body portion adapted to receive a reciprocatory valve, spring means for normally retaining said valve in upward and closed position, said valve having attached therewith and wholly supporting a receptacle platform, said valve being adapted to open upon a dmvnward pressure .on said platform and to close automatically upon the release of said pressure, the entire valve actuation mechanism operating in a vertical plane.

A fluid dispenser comprising a body portion adapted to receive a hollow sleeve valve, spring means for normally retaining said valve in upward and closed position, said body and valve having inlet and outlet ports, said valve having a stem carrying a receptacle platform, a pipe leading from said body out-let port to a point adjacent said platform said valve being adapted to open upon a downward pressure on said platform and to close automatically upon the release of said pressure.

3. A fluid dispenser comprising a body portion adapted to receive a hollow sleeve valve, spring means for normally retaining said valve in upward and .closed position, said body and valve having inlet and outlet ports, said valve having a stem carrying a receptacle platform, a pipe lead ing from said body outlet port to a point adjacent said platform said valve being adapted to open upon a downward pressure on said platform and to close automatically upon the release of said pressure, said pipe being provided with a swivel joint near its upper portion.

4. A fluid dispenser comprising a body portion adapted to receive a hollow sleeve valve, spring means for normally retaining said valve in upward and closed position, said body and valve having inlet and out let ports, said valve having a stem carrying a receptacle plat-form, a pipe leading from said body outlet port to a pointedjacent said platform said valve being adapted to open upon a downward pressure on said platform and to close automatically upon the release of said pressure, said pipe being provided with a swivel joint near its upper portion, said valve body having a top plate with a square aperture, said valve stem being of square cross section in accordance nith said aperture to prevent rotation of the valve and non-alignment of the several valve ports with those of the valve body.

In testimony whereof I affix my signature.

HENRY o. FITL.
