This invention relates to refrigerating apparatus and more particularly to a portable apparatus adapted for cooling drinking water.
It is one of the objects of the invention to provide an apparatus of the'type-referred to, that will. have its units so arranged that they will operate efliciently and will be adapted for convenient assembly and disassembly. A
further object of the invention is to provide an apparatus adapted to support a large container for the drinking water directly from the base of the apparatus, by means of columns which extend to the top and are pro- 1 vided with means for supporting the units in a substantial manner.
A further object of the invention is to provide an apparatus of the type referred to in which the cooling coil for the refrigerant is located adjacent the top of the apparatus and so exposed that there will be a free circulation of air aroundthe coil, with the other units of the apparatus so located that they will not be aifected b the heat which is dissipated from this coo ing coil.
Other objects of the invention and the features of novelty will be apparent from the following description, taken in connection with the accompanying drawings, of which Figure 1 is a side elevation of an apparatus embodying my invention, a portion of the casing being broken away to expose some of the'units;
Figure 2 is an enlarged vertical section through the upper part of the apparatus, the section being on the line 2-2 of Figure 3;
Figure 3 1s a transverse section on the line 3-3 of Figure 2;
Figure 4 is a plan view of the supporting ririg for the water container;
Referring to the drawings, and particularly to Figure 1, it will be noted that the apparatus comprises a base 10 that is mounted on casters 11 and carries three tubular pillars 1 2 which are secured to the base by bolts 13.
A bracket 14 is mounted on the base 10 and preferably insulated therefrom by the blocks 15, the bracket being secured to the base by the bolts 16. An electric motor 17 is mounted on the base of the bracket 14 and a compres- S01 18 is secured to the bracket by the bolts 19, slots 20' being provided in the bracket to permit vertical adjustment of the compressor for the purpose of tightening or loosening the belt 21 by means of which the compressor is drivenby the motor 17. The motor 17 is provided with a pulley 22 and the compressor18 with a pulley 23 and the belt 21 operates on these pulleys.
The pillars 12 have brackets 24 secured thereon by means of the U-bolts 25 and these brackets carry'a plate 26 which serves as a partition to separate the space within the jacket 27 into two chambers, the space below the partition being the compressor chamber and the space above the partition being the 7 refrigerating chamber. The jacket 27 is supported on the base 10 and carries an ornamental flange 28 on its upper end.
The upper ends of the pillars 12 are tied I together by a conical ring 29 which has radially projecting arms 30 that are secured to the tops of the pillars by means of bolts 31. A cover 32 has a central funnel-shaped depression 33 which rests on the ring 29 and is adapted to receive an inverted bottle 34, this bottle containing a supply of drinking water.
A container 35 is supported on the partition 26 and serves as the refrigeratingchamber for the drinking water. This container has a cover 36 secured thereon so as to be tightly sealed thereto and a supply pipe 37 extends upwardly from the cover 36 and has its upper end telescoped over the flange 38 on the lower end of the funnelshaped portion 33 of the cover 32. The water is suplied to the container 35, from the pipe 37, y means of a central opening 39 in the cover 36. A cooling coil 40 is arranged within the container'35 and suspended from the cover by means of a plurality of pairs of supporting bars 41 between which the convolutions of the coil 40 are clamped.
A cooling coil for the refrigerant is shown at 42, this coil being of helical form and arranged between the flange 28 and the cover 109 32. The coil is supported'by meansof hangers, each of which consists of a pair of bars 43 between which the convolutions of the coil nected are clamped, one of the bars of each pair having a laterally projecting arm 44 which The refrigerating system comprises, in
addition to the compressor and coils 40 and 42, an expansion valve 45, which may be any of, the well known forms and which is connected with the lower end of the coil 40 by means of a pipe 46, and with the lower end of the coil 42 by a pipe 47. The compressor 18 has a discharge pipe 48 in which there is an oil separator 49, this oil separator having contherewith a pipe 50 which extends upwardly and'is connected with the upper end of the coil 42. The upper end of the coil 40 bedded in suitable insulating material such,
extends through the cover plate 36, as shown at 51, and is connected by means of the pipe 52 with the intake of the compressor 18. 1 By this arrangement the compressed refrigerant is conducted from the compressor 18 to the,
upper end of the cooling coil 42 whence it flows downwardly through this coil to the expansion valve 45 and from the latter to the lower end of the refrigerating coil 40., The
refrigerant is conducted from the upper end of the coil 40 back to the intake of the compressor.
A discharge pipe 53, for the drinln'ng'water,
is carried by the cover plate 36'and extends to a point near, the bottom of the container 35.
A, laterally extending pipe 54 has connection with the pipe 53 above the cover 36, and ex tends through the jacket 27 and carries a faucet 55 at its outer end. A vWaste'tank 56 is secured to the jacket 27, below the faucet 55, and may be drained by means of the cock 57. The usual hermostat for controlling the operation of the compressor in' accordance with the temperature of the water in the chamber 35 is shown at 57 I. I
In practice the container 35 should be emas cotton, cork, or any of the other commonly used insulations.
From the foregoing, it will be seen that the bottle 34, which constitutes a water supply container, is supported vfrom the base 10 by means of the pillars 12, these pillars being substantially secured together at their middle by the plate 26 and at the upper end by the ring 29 so that a very rigid structure is pro- "vided. The parts are readily assembled and disassembled and, when the cover 32 is removed, the expansion valve 45 as well as the connections to the coils 40 and 42 are easily accessible through the top of the coil 42.
The coil 40 may be removed from the container 35, without detaching it from the cover plate 36. The space within the coil 42 is left open so as to permit a free circulation of air through the coil and since the heat, which I water remamlng 1n p r ly,
get to the refrigerating chamber 35.
"The advantage of having the pipe 53 extend to a point adjacent the bottom of the chamber 35 and'having the faucet 55 located above this chamber is that the coolest water will always be drawn from the chamber and when the supply in the bottle 34 is exhausted, there will still be arelatively large supply of cool 37 which will beavailable for use when the empty bottle has been replaced by a filled one. In other words, water cannot be drawn from the faucet 55 unless the level in the pipev 37 is above the faucet.v
Having described'my invention, I claim:
1. In refri erating-apparatus, the combination'of a. ase, a p'lurality' of pillars secured to said base, a motor-driven pump mounted on'said base, a partitioncarried by said pillars, a refrigerating chamber carried by said partition, a member attached to said pillars at the upper end thereofand adapted to support a water-container, a'cooling coil surrounding said byabovesaid-chamber, a refrigerating coil 'insaid chamber, and connections between said vcoil and said pump whereby the refrigerant V is circulated. f 2. vrefrigel?'ating said base, a refr gerating chamber .adapted pillars and supported thercto conta n arefrigerating coilcarried bysaid P l ar n h v n alwa r s pp y P tending-upwardly, aqmember secured to the upper ends of said pillars,
