Be it known that l', ROY J. Scotrr, a citizen of the United State, residing at Canton, in Stark county and State of Ohio, have invented a new and useful Refrigerating Appliance of which the following is a specification.

This invention relates to the automatic regulation of refrigerant to cooler in a refrigerating plant.

The objects of my invention are first; to automatically regulate the supply of refrigerant to cooler, second; to always maintain the coils in cooler in a flooded condition. third; to always furnish .dry to refrigerating machine, fourth; to return" gases gene ated by refrigerant in cooling itself direct to refrigerating machine without first passing through cooler.

I attain these objects by the mechanism. illustrated in the accompanying drawings.

To further describe 'my invention, numeral 1 indicates the lower body portion. To the lower body portion 1 is a flange 2 which will be hereafter described. The upper body portion indicated by 3 has a flange 4 similar to flange 2 of the lower body portion 1. To the top of the upper body portion 3 is a similar flange 5 for the purpose of fastening the top 8 by means of bolts 9. A wall 6 which separates body 1 and 3 is held in position between flanges 2 and 4: by means of bolts 7. The purpose of this wall will be hereafter described. To the lower extremity of the body 1, enters a liquefied gas-supply pipe 10, on th outside of body 1, as best illustrated in Fig. 2.

To the pipe 10 is attached a regulator 12 and from which said regulator is attached pipe 18 which said pipe runs to the outside of body portion 1. An elbow 1% is provided to run pipe 13 upwardly to elbow 15 and into body portion 3 from which said gas enters pipe 16 which will be hereafter described. The wall 6 has a U shaped cylindrical body portion from which pipe 17 runs through the center and attached to the lower end of 17 is a collar 18 which has web-ivork 19. which web work is for the purpose of allowing the liquid to flow through into chamber 20 and down into outlet '21 and out to the evaporating system which is not necessary to show. A check valve is used to check it from coming back into clmmber 220.

To the top ofcollar 13 is attached a bell 23 which will. be hereafter described. To the'lower end of collar 18 is attached by means of screw threads, rod 24 which said rod slides through guides 32 and 33, which guide 32is attached to bodyQQby means of bolts 3% and 35.

Guide 33 attached to body 29 by means of bolts 35 and 345*.

A slotted regulator arm attached to regulater 19 operates in a fork l6 which said fork 46 has a roller 4-3 held by pin 49 operating in the slot of the arm 25, which said fork 16 is attached by neans of screw threads to the rod 24. A. collar 45 is arranged on arm Ql to limit the upward movement of pipe 17 and bell 23. The body 29 has a flange 30 which flange 30 is attached to flange 28 of body 1 by means of bolts 31. It 'will be noticed that there is a space 36 between body 1 and body 29 which in said space 36 is placed the cylindrical bell 23. Mercury will be poured into valve 44 which will enter space 36 for the purpose of making a seal betweenspace 20 and 37.

The purpose of making the center of body 6 in a U shape is to provide a space 38 into which said space enters a bell 39 screwed onto pipe 17. Space 38 is filled with mercury for the purpose of creating a seal be tween separator 3 and space 37.

As liquid refrigerant evaporates, gases generated thereby pass through pipe 26, through enlarged end 27, where any entrained liquid will be dropped to base of separator 3, and. the dry gas will pass out through 16 to refrigerating machine.

A filling valve 43 which is similar to that of 44: is for the purpose of pouring the mercury into space 38 which of course you will understand-that it is dropped onto body 6 first and then flows into space 38. For the purpose of equalizing the pressure between the space 37 and interior of separator 3 a pipe 40 is screw threaded into body 1 and to which said pipe 40 is attached a regulating valve 41 and pipe 42 which, at the top, enters separator 3. The operation is'as follows Liquid re frigerant is introduced under a high pressure to pipe 13 from a receiver, flows through stop valve 11, continues through expansion valve 12, where it is reduced to suction pipe pressure, continues through 13, 1% and 15 to interior of separator 3, where the refrigerant cools itself and the gas generated thereby passes through suction line of refrigerating machine, through pipe 16, remaining cool liquid flows through pipe 17, through coupling 18, through web work 19, to space 20, through pipe 21, through check valve 22 to cooler. As cooler fills with liquid refrigerant, a hydrostatic pressure is created beneath bell 23, causing it to rise, carrying with it guide rod 24, which operates lever 2 5,thus closing expansion valve 12, as refrigerant in cooler evaporates sufficiently the hydrostatic pressure beneath 23 decreases,-causing it to assume a lower position, again opening expansion va1ve12. To the lower extremity smaller bell attached to top of said pipe, said smaller bell projects downwardly into a cylindrical pocket filled with mercury forming a seal between upper and center compartments, an inlet pipe for liquid refrigerant and containing an expansion valve, connected with said upper compartment, a liquid refrigerant outlet pipe connected with said lower compartment leading to a refrigerating coil, a refrigerant vapor pipe discharging into said upper chamber, a vapor outlet from said upper chamber and a rod connected at one end to said web collar and at the other end to said expansion valve.
