,LTO alllwhont it may concern; Be it known that I, MADISON 7 Minneapolis, in the couutyof Hennepin and v Stateof Minnesota, haveinv'en'ted certain new and useful'lmprovements inBefrigerating Apparatus; and I-do hereby declare the following to be a full, clear and exact description of the invention, such as will enlo able others skilled in the art to which it appertains to make and use the same. I My invention relates to refrigerating apparatus, and has for its object'to provide an improved system which shall be simple and '15 cheap in point of construction and economical and 'eflicient in point. of operation. To these ends myinvention consists of the novel combination of devices hereinafter described; and defined in the claims.

Fig. 1.

5 room 2, which is intended to be cooled.

The invention is] illustrated in the accompanying drawings,'wherein like notations refor to like parts throughout the several views.

Figure 1 is a sectionalelevation through the preferred form of my apparatus with some portionsbroken away. Fig. 2 is a de-' 5 that shown in Fig. 1, but having a modified 1 form of circulating connection.

Directing attention first to the preferred form of my apparatus as illustrated in Figs; 1 to 4, inclusive,, the numeral 1 represents a 40 suitable tank or receptacle for the application of the primary refrigerant to the secondary or circulating refrigerant. The said tank 1 is located at a higher level than the medium, such as the air in a storage or other The primary refrigerant 3 may be'a mixture of salt and ice, as shown in Fig. 3, or may be of any other suitable freezing mixture adapted to produce the cold desired. 'lhesecondary or circulating refrigerant 4 may be ordinary brine or any other suitable non-freezable' liq-- Ooornn, Jr, a citizcn of the United States, residing at" cooled in any suitable .way.

they are shown set edgewise within the storage-room 2 for cooling the air.

uid. This secondary refrigerant circulates through an endless circuit, the upper part of which circulating-circuit is subject .tothe primaryrefrigerant 3 within the tank land is exposed within the medium intended to be cooled thereby-as the air, for example-in the storage or'other room 2 at a lower level than the tan-k1. This circulating-circuit may take any suitable form adapted to the purpose, but should preferably have ex 'the lower portion of which circulating-circuit tended surfaces in its upper portion subject I to the refrigerant in the tankl and extended surfaces in its lower portion applied to cool the air or other surrounding" medium, such. as water, to which the cold isintended to be applied. in the preferred form of my apparatus I provide a circulating-circuit having upper sections 5 and lower or cooling sections 6 made up of sheet metal into the form of thin shells or hollow slabs. The side w. 115 ofthese cells 5 and 6 are shown as connected by stay rivets7 for giving to the same the requisite strength. The uppershells or sections dare provided with marginalfianges 8, which work between the lips of suitable guide-lugs 9, fixed to the interior walls of the tank 1. These guides 9 are so disposed as to permit the said upper shells 5 to be inserted in and removed from working position endwise and to hold the same properly spaced apart from each other within the tank 1 for the proper application of the refrigerant or freezing mixture 3, as best shown in Fig. 3. The lower shells or cooling-surfaces 6 are on posed within the air or other medium to be For example,

A pipe-section 10 connects the lower end of each upper section 5 to the lower end of a cooperating cooling-section or shell. 6 at the lower level, and a pipe-section 11 connects the opposite and highest end of said cooling section. or shell 6 to the highest point of the upper section or shell 5 most remote from the outlet-pipe 10. The pipe-section 11 is also shown as provided with. an extension 12, extending upward beyond the level at which the pipe 11 taps the shell 5. on theoutside of the tank 1 to provide space for the expansion and contraction of.
