'Y Specification form-ing part of Letters Patent No. 39,331, 'dated J u ly 2l, 185.3.

Toall yghom it may concern.-

Be it known that I, SAMUEL It. SYLVESTER,

yof the'city and -county of .Washingtom Dising drawingamaliinga part of this specification, in which- 5v Figure'lis a side elevation, andFilg. 2 isa forms apart of my invention:

verticalv transverse section, of my pump, which sponding Aparts in the drawings.

. This'nvelltion relates to that-classof sodawater fountains in which the effervescence is produced` inthe drinking-glass lay-bringing a solution of supercarbonate of soda or other proper material in violent contapt with acidulated sirups, .producing sodafwater 6i superior quality at greatly-reduced cost..V

To enable those skilled in the`art to fully understand and coustructiny invention, I will proceed to describe it. u i

A represents a section of' a counter or other suitable framing upon which is placed the urri or discharging device B, which is properly se- 'cured upon the top thereof A',

GL's a pipe of lead or other suitable material, leading from the urn B toa pump, D, which-is secured to the upright portion ofthe counter A at a a. Another pipe, c,connect's the lower portion of the pump with a* suitable reservoir, E, placed in any convenient position below -the urn or dischargingpipe B,

. -lo thepump D, constructed in 'the ordinary manner, and forming a. part.. -of the same, l. construct an air-chamber, F, ,the 4 bottom of which isa movable valve or circular plate, G, working air-tight, or'nearlyscfand resting on stops g g, and iitted with ahoie in its center, through which the piston d of the pump is aL lowed to work.

H isa oap forming the top of 'the pump,

`with a puckered hole in the center, through which the piston d' works air-tight, and which pump or fastened by any other proper means. l is 'a 'coiled or spirak spring surrounding to the, valve G and theupper end resting against the cap H. rlhe object of this airchamben with its valve and spring, is to produce a uniform velocity of discharge of the solution and` continue the same after the piston ceases its upward movement, and which is accomplished. by the reaetionotl the coiled Similar letters of reference indicate' corre-Y spring pressing downward on the valve.`

pipe ot tl'e'urn B at any suitable point, by which the discharge is governed.

To 'operate my inyentiou the reservoir is filled and the upward stroke of the pump iills the pipes, and the discharge is made/with a velocity equal to the pressuge given tothe piston of the pump.

It is a wellknowu fact that the beverage ordinarily furnished as soda-water is simply a 4mineral water and destitute ofsoda, while by this process, which is cheap and portable, a plre article of soda water is in the reach of Having thus described my intention, what I claim as new, and desire to have secured by Letters latent, is-. '1. The directydischargebf the solution from a single reservoir by means of aspring-pump into the drinkingglass 3,.

2. The pump arranged with a springer afrchamber, or spring and air-chamber and valve,

as and for the purpose set forth.

3. Tho'combinatiou of the single reservoir pipes. spring,pump, and dischargingpipe', sub'- stantially as set forth. f
