FRANCIS NICHOLS, OF NEW LONDON, CONNECTICUT.

SODA-WATER APPARATUS.

Specification of Letters Patent No. 32,709, dated July 2, 1861.

7b all whom it may concern:

Be it- known that I, Francis Nichols, of New London, in the county of New London and State of Connecticut, have invented a 5 new and useful Improvement in Soda-Water K Apparatus; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming part '10 of this specification, said drawing representing a vertical section of a soda-water counter, with such parts of the apparatus as are necessary to illustrate my invention.

My invention consists in so combining the '15 casing of the draft-tube with the cooler by means of suitable pipes, that said casing is made to constitute a portion of a siphon through which the waste ice-water from the cooler is caused to circulate, for the purpose f 1° of keeping the draft-tube cool. It also consists in so constructing a casing surrounding the syrup vessels and so combining the same with the cooler by means of pipes as to make the said casing form a portion of a 15 siphon by which the ice-water is caused to be drawn from the cooler, the latter siphon being the same. by which the ice-water is drawn through the casing of the draft-tube r or a separate one.

To enable others to make and use my invention, I will proceed to describe its construction and operation.

The drawing represents the casing- of the draft-pipe and the casing of the syrup ves^:’>5 seis as parts of the same siphon.

to A, is the counter; B, the casing of the draft-tube, erected upon the counter in the usual manner.

The cooler, C, arranged under the coun^ί() ter; the pipe, D, from the fountain, taking the form of a coil within the cooler; and the pipe, E, leading from the coil up to the draft-tube, F, are all represented in red W outline to distinguish them from the parts ( 15 to which my invention more particularly

I relates.

G, is an india-rubber or other pipe con| nected by a nozzle, «, passing through the top of the counter, with the bottom of the casing B, and entering the cooler C; such * pipe combining with the casing B, to form the shorter leg of the siphon.

⁵ H, is a metal pipe secured in the bottom of the casing B, extending upward therein ⁵³ nearly to the top of the said casing and projecting through the bottom thereof to form a nozzle, b, to pass through the counter for the attachment of an india-rubber pipe, I, below the counter, the latter pipe being connected with a nozzle on the casing, J, of the 60 syrup vessel's, which is arranged on a suitable shelf or support below the counter. This casing J, consists of an air-tight box of tin plate or other metal, containing any number of syrup vessels, c, c, according to 65 the number of different kinds of syrup desired; such vessels being soldered or otherwise secured in an air-tight manner in openings in the top of the said box, and consequently being entirely immersed in or sur- 70 rounded by water when the said box is full.

L, is a waste-pipe, connecting with the bottom of the casing J.

The pipes I and H, the casing- J, and the pipe L, constitute the longer leg of the 75 siphon, care being taken that the mouth of the tube L is lower than the mouth of G. The pipe I, may be provided with a cock to regulate the flow of water in the siphon. The siphon may be filled to start its opera- 80 tion, by closing the ends of the pipes G and L, or raising them above the top of the draft-tube casing B, taking off the cap, d, of the said casing, and pouring in water at· the top of the said casing; removing also 85 a plug, p, in the top of the casing of the syrup vessels until the said casing is full.

When the cooler C is supplied with ice. and the siphon is in operation, the waste water resulting- from the melting of the ice 90 collects at-the bottom of the cooler and is caused to flow up the pipe G, through the casing B, around the draft tube down the pipes H and I, through the casing J, and around the syrup vessels escaping by the 95 pipe L, cooling in its passage both the drafttube and the syrup vessels. The escape by the pipe L, should however be so regulated that it does not carry off the water faster than it collects in the cooler C, or the action ¹⁹ j of the siphon will be stopped by the entrance of air. By this mode of carrying off the waste water, which leaves the cooler at a temperature of about 32° Fall., much ice is saved, as the water is usually thrown away ¹⁰⁵directly from the cooler; and besides this saving of ice, the necessity for the use of any ice above the counter, for filling casing B, or cooling- syrups, is obviated.

I employ tor drawing the syrups from the ¹¹⁰vessels c, c, any of the well known elastic syringes, as these can be. very conveniently

32,709 operated under the counter and if of proper size will measure the proper quantity of syrup for each glass of soda-water. One of these syringes, lettered M, is represented in the drawing.
