REFBIGERATING UNIT.

Application fried October 27, 1927. Serial No. 229,009.

This invention relates to improvements in dbmestic refrigerating plants and more particularly to the refrigerating unit placed in" the fcfrige'rating'or icc chamber of a 1. msrici@em; Q p

it an object of this invention to proa ir-ie a refi igcrating -unit employed inarlo- Inestic refrigerating machine o t the compression type employing the flooded system with a float valve chamber for regulating the supply of the refrigerant which will be connected directly to the unit without substantially increasing the width thereof. In systems of this kind employed in this type of domestic refrigerating machine, it has been customary to construct the refrigerating units in sections and it is an object of this invention to insert the float chamber between the'upper connection of such sections and a spacer of equal width between the lower connection of such sections, whereby the float valve chamber may be said to become an integralspart of the refrigerating unit contained within the-refrigerating or ice chamber of the ice box.

While the preferred form of this invention is illustrated upon the accompanying sheets of drawings, it is to be understood that minor detail changes may be made without departing from the scope thereof.

In the drawings: Figure 1 is a view in perspective illustrating the preferred form of this invention. Figure 2 is a view in vertical transverse section taken on the line 2-2of Figure 3, looking in the direction of the arrow.

Figure 3 is a view in longitudinal vertical section taken on the line 3-3 of Figure 2, looking in the direction of the .-.rrow.

As above stated it is customary in this art to construct units of this character in sections. Two of such sections, 1 and 2, are illustrated in Figure 1 connected to each other at the top and bottom by bolts 3. Each section is hollow, as shown in Figure 2, the interior of which communicates with enlarged central bosses 4 at the top and bottom thereof, the adjacent or meeting edges of which are provided'with a tongue and groov e connection, as shown in Figure 2, and. the sides of each section are provided with vertical and horizontal outstanding ribs, as shown in F igures l and 2. In aceordance with this invention a float chamber 5 is provided with a depending boss 6, haverection therewith and held in gas and liquid tigl'it Contact by the bolts 3. The interior of the float chamber communicates with the interior of the boss, as shown in Figure 3, and the float chamber boss communicates with the interior of the section boss 4, as shown in Figure 2. A tubular spacer 9' having similar means for forming a gas and liquid tight connection with the lower section bosses at is inserted therebetween, as shown in Figure 2, forming a means of communication between the bottom of these sections.

The float chamber 5 is provided with a float operated valve 10 operated by a float 11 arranged in said chamber, which valve is provided with a connection 12 to the high pressure side of the ice machine compressor- .and is so constructed that the valve remains open until the liquid refrigerant fills the sides and bottom of the section and its level rises in the float chamber, as indicated by the dotted line on Figure 2, suflicientlyto raise the float and close the valve. The float chamber 5 is also provided with a conneetion 13 to the low pressure side of the compressor, which,,during its operation of the ice machine, relieves the pressure above the liquid in the float chamber, whereby the refrigerating liquid is evaporated and passes ofi' therethrougll. During evaporation the refrigerant absorbs heat from the surrounding atmosphere which reduces the temperature of the refrigerating or ice compartment of the-ice box. The operation of the float 11 is the normal operation of the customary float valve in this type and system of ice machine. i

This particular construction provides a very simple'means for connecting the float .valve chamber 5 to. the unit at the proper level without increasing the width of the unit to any great extent. Float valve cham 105 bers vare usually employed for the same purpose as this one in units of this character and are either connected to the side of a section or attached to the'side of the refrigerating orice compartment of the ice 110 boil- The refrigerating units are customarily constructed so as to be received within refrigerating or ice compartments of a standard size ice box with but little'space 'isions at -=the side of such a unit.

to spare on either side so that it is diflicult to install a float chamber of proper dimen- It is to be 1 '1oted in the present invention that the Afloat chamber boss 6 is only of such width "as'to provide proper communication between i the section bosses and chamber and depends below the float chamber so that the float chamber may be of any desired diameter and the width of the entire unit is only increased by the width of the boss. This .particular type of float chamber and means for attaching the same between the sections provides an efiicient device readily adapted to standard sections for refrigerating units.

" illustrated upon the drawings, the ice cube" tra s 14 are supportedupon the hori beclosed, if desired, by a door hingedto the upper edge of said plate in the customary manner. 7

- What I claim is:.

' -1.' A refrigerating unit comprising hollow spaced apart side sections for containing the refrigerating fluid,- a tubular spacer interposed between said sections at the bottom and communicating with theinterior thereof, a float valvechamber, a tubular boss de.. pending therefrom corresponding in width to said spacer and interposed between said sections at the top and communicating'with the interior thereof and with said chamber, a float and float-operated valve within said chamber for controlling the admission of the refrigerating fluid.

2. A refrigerating unit comprising hollow spaced apart side sections for containing the refrigerating fluid having corresponding tubular bosses at the top and bottom of theadjacent sides projecting in line each with the other and-commumcatmg with the 1ntcrlor of the respective sectlons, a float valve chamber, a tubular boss depending therefrom of lesser width than said chamber and interposed between and in communication with the upper aligned side bosses, a tubular spacer similar in width to the valve chamher boss interposed between and in communication with the interior of the lower aligned side bosses, and a float and float-. operated valve within said valve chamber for controlling the admission of the refrigerating fluid.
