ATTORNEY- mi. A bifurcated journal luglM extends from each shank S03, and a disc I extends from each plug E52. A washer Hi6 encircles each plug Hi2 between the head if and the disc I05. Each washer l-GS has imbedded therein the circular spring I93, to prevent the washers becoming distorted. u

A link 5 G8 in each of the pistons I09 has its ends pivoted to the long arm 85 of its adjacent lever 83 and to the accompanying bifurcated lug I94.

From theupper portion of each of the hoods 35 extends a bifurcated journal lug H2, and in each of the lugs l i2 is pivoted a supplemental operating lever having the long arm H3 and the Each of the short arms H4 is up against its accompanying short arm HQ. adapted .to bear pivot pin 9|.

To operate the multiple dispensing and measuring device, the inlet nozzle 23 is connected to a source of supply of a fluid to be dispensed, and the second inlet nozzle 29 is connected to a source of supply of a secondfluid to be dispensed and mixed with the other or first fluid. For the purpose of exemplification the flrst'fluid maybe coffee-and the second fluid may be milk;

The operator adjusts both the needle valves 14 to a predetermined position to locate the tapered ends 16 in proper position in the vent openings iii, to control the effective area of each of said vent openings 18.

The operator next swings down the operating bar 56 of the handle 53 in the direction of the arrow A, Fig. 4 and thereby the operating lugs 60 bear up against the pins '62. By this means the operating plate 93 is raised and thereby both the operating levers 83 rise. -The stop lug 6| prevents the operating handle 53 being swung too great an extent, by being adapted to contact with the connecting portion 50. ,When the operating levers 83 .rise the valves 92 are raised from their valve seats 32, and both the thimble shaped pistons I00 are also simultaneously raised. .By this means the fluidsthat enter both the valve chambers 29 and 2|, flow therefrom through the openings 33 into the mixing chamber 61.

The mixed fluids escape from the chamber 6'! through the discharge nozzle 65. It will be noted that the operator releases the bar 56 when the lug 61 contacts against the connecting portion 50 when the operator releases the operating bar 56, the tension of. the springs 99 will seat the valves 92 independently of each' other ontheir valve seats 32 and the flow of the fluids is gradually cut oil.. During the descentof the valves 92, the pistons [90 also descend. During the descent of the pistons W9 the air in each, between the washers Hi6 and the partitions H is compressed and escapes through the vent opening '52 and enters the chamber 13. The air escapes from the chambers l3 through the vent openings E8; The discharge of the compressed air through the openings is controlled by the position of the tapered ends it in the openings F8. The annular. opening between the wall of the opening 18 and the tapered end 16 is varied by locating the needle valve 14 in different positions. By adjusting the needle valves 14 in different positions the downward strokes of the valves 92 are retarded and the speed of travel of the down stroke of each of the valves 92 differs or is the same. Thereby the interval of time for each of the fluids flowing through the device may differ or be the same. By this means the ratio of the fluids in the mixture discharged from the discharge nozzle is easily controlled. For example the amount of milk dispensed for a certain quantity of coffee is easily controlled by means of the needle valves 74.

In case a large amount of either fluid is to be dispensed the operator swings down the arm I [3 of either supplemental operating lever, and maintains it in its lowered position until the required amount of fluid flows through either one of the valve chambers 20 or 2| and is discharged from the nozzle 66.

Various modifications may be made in the invention and the present exemplification is to be taken as illustrative and not limitative thereof.
