Original application filed January 12, 1924, Serial No. 685,890. Divided and this application filed September 8, 1924.
This application is a division of my copending application on carbonating apparatus, Serial 685,890, filed Jan. 12, 1924.
The object of my invention is to provide 5 a novel carbonating apparatus adapted for using carbon dioxide snow or ice for simultaneously carbonating and refrigerating a I liquid, especially where the carbon dioxide snow or ice is deposited in a sealed container in communication with a second container in which is the liquid to be carbonated; and to provide the novel combination and arrangement of parts described in the accompanying drawings in whic The figure is a vertical longitudinal section of my invention wherebyv the water tank and pressure regulating apparatus of the present carbonating systems are utilized in connection with the use of carbon dioxide snow or ice to supply the required carbonic acid gas under pressure to simultaneously carbonate and refrigerate the liquid in the Water tank.
Referring to the drawings, I provide a suitable tank or container 1 opening into which is a suitable inlet and outlet pipe 12 for admitting and withdrawin the liquid to be carbonated and refrigerate this liquid ordinarily being water. Pipe 12 is provided with a T-pipe' fitting 13, connected with the inlet or supply pipe 14 and to the outlet pipe 16 extending to the fountain or wherever the carbonated liquid is to be used. I further provide a sealed chamber 17 for holding the carbon dioxide snow or ice, said chamber 17 being in communication withtank 1 by means of a connecting pipe 18, having a reducing valve 19 and terminating in pipe 20, which opens into the 4 lower portion of container 1. While the drawings do not show any agitating device, it is within the contemplation of my invention to utilize any suitable and eflicientagitating means of conventional construction, such as is at present used in other carbonatin devices.
ere it is desired to use carbon dioxide snow with the conventional tank and systems now in use, I provide a second con- I0 tainer 17 of suitable size to receive inder of carbon dioxide snow 11. This second container is in communication with the main container 1 through a pipe 18, reducthe cy1-. b

ing valve 19, and inlet pipe 20 positioned near the bottom of the first container. It is provided with a sealing device, as illustrated in the drawing, adapted to effect an air-tight seal by pressure exerted on the device from within the container or tank 1. The melting carbon dioxide in container 17 flowing through, conduits 16 and 20 will carbonate and refrigerate the liquid 2 in container 1 and build up a pressure in container 17 that will cause the carbon dioxide gas to discharge into container 1 as described. It obviates the use of the heavy steel container in use at present. The container 17 being of small size may be made cheaply and may be tinned on the inside to prevent rust, making it much more sanitary than the large steel containers at present in use, While the body of carbon dioxide snow, unlike water-ice, contains no impurities.
Owing to the high ressure necessary to store and handle. liquid carbon dioxide, it has been necessary heretofore to have very hea steel tanks inwhich to store'it, the weig t of these tanks ordinarily being about four times the weight of the liquid carbon dioxide which they contained. It has therefore been necessary to handle a total of five times the weight of liquid carbon dioxide to be delivered in order to deliver this material from the factory to the consumer. And in order to keep the ratio of weights at even four to one, it has been necessary to make these tanks of a weight approximating 200 pounds to hold 50 pounds of carbon dioxide, thus making a total of 250 pounds to be handleda very heavy article to be handled by one man in the process of delivery. The opening in the tank is necessarily small and the conventional tank tends to rust on the inside and become dirty and unsanitary. Besides, it is very diflicult to clean this small opening. By converting the carbon dioxide to snow and compressing it into compact, preferably cylindrical bricks 11, it may be delivered very conveniently, with very little if any additional livered with it.
My invention includes not only the caronating apparatus disclosed but the method of simultaneously refrigerating and carbonating a liquid by placing a body of carbon dioxide snow in or in communication weight necessary to be de-.
with a closed container nearly filled with the liquid to be carbonated and refrigerated and tightly sealing this container while the snow melts or reverts to its normal gaseous state, thereby producing the desired carbonating and refrigerating effect, reducing the temperature of the li uid to the extent of the difierence in the cai bonating pressure and the pressure of 1i uid carbon dioxide.
The carbon dioxide snow when compressed has the appearance of and a greater density than ice. Throughout the specification and claim the term carbon dioxide snow or snow is to be construed as referring to the product, whether in its porous or compressed form.
What I claim is The method of operating a closed container for liquid, in combination with a closed container for carbon dioxide having a conduit for discharge into said liquid container, which method consists in substantially filling the carbon dioxide container with carbon dioxide snow or ice, causin said carbon dioxide container to absor heat, thereby generating high pressure therein and then causing discharge of the resultant carbon dioxlde gas or liquid into the liquid to be carbonated and refrigerated thereby.
