JOHAN GUSTAF-VRICHERT, OF STOCKHOLM, SWEDEN.
nnriucsnnrmo APPARATUS.
Specification ofLstters Patent. P3 tented NOV, 24, lglzL zipncafion mea December is. 1913. senai No. 507,479.
To all whom* it may cof/mem:
Beit known that I, JonAN GUs'rAr RICH- fiEn'r, n; subject o fthe King of Sweden, resid-` ing ati-No. 16 Norrmalmstorg, Stockholm,
in 'thel Kingdom ofiSWcden, haveinvented certain new iand useful ,Improvements in Refrigerating Appar'a'tugvof Which the foi- 'lowing'is a. spe'ciication.
In refrigerating apparatus eomprising in combination an ice reccptacle, ,a sait reeeptacle, "a refrlgerating member for lnstance a. refrigerating pipe and a liquid circulating 'through the'said parts during the action of a pump, it is necessary to arrange lstreiners of'some kindpfor preventing the dirt, sawdust or such like, which may be on. the ice when placed in the ice receptacle v v from 'passing intoj the pipe system. The
said strainers have hithertoin most cases heen-*arrangecl in the bottom of the ice retieptacle, Which lhas made` it very. incon- .strainer receptaclc, so that same can be in-` venient to clean 'the strainers, as they'xire always put under. the pressure of' the cir- V*ouhrting liquid'in the pipes andreceptacles.
T1113. .lnconvenience' is avoidedby the present.
invention', .'Which 'consists therein, 'that the strameris arranged .in especial' receptacle,
located above the refrigerating member,
'coii'taining the refrigerating liquid. By this a Vfree water surface.. is establisl'ied in the spected even during the run of the whole installation and the strainer can' becleaned Without the installation being stopped and 'fa ithout .the refrigerating liquid being drawn From the reccptacle the liquid ows mto the pipe system by gravity.
The invention further consists in a device for 'prevent-img the refrifzcrating liquid, 'When the temperature'has reached the dcsired low point, from circulating through the'refrigerating members, This is established by means of a thcrmostat operating the outlet opening from the strainer re- .ccptacle to the refrigerating members. i/Vhen 'the temperature. is normal, the thermostat leaves the said opening free; When the temperature reaches the lowest point desired the thermostat the opening, so that no part of the refrigerating medium can flow into the refrigcrating pipes.V The liquid as forced by the pump to the strainer receptacle will then flow through special pipe back to the pump.
- the water.
One embodiment of the invention is shown on the annexcd drawing, n-'hcre-- Figures'l and 2 are diagrammatic views of a refrigernting car rcspectively in cross and longitudinal section. Figs'B and 4 show respectirely in longitudinal section anil in plan on a greater-'scale the strainer regrate or lattice g and is admitted to the. generator by .means of the opening k in the roof of the car, said vopening being'clpsed by` the insulated cover The compartmenis d and dl .are connected with .each other by means of the :pipe
from which .the inlet pipes lead to the pumps l and lx, 'the cleaning pipe m,with the Valve` m1 and the overflou" pipe n from the strainer receptacle o.
p isan overfiow `pipe for 'the surplus of r vare openings', closed by Watertight covers, by means of Which openingsjthe lattice or grate g as Well as the bottom of the generator can be cleaned.
The strainer. receptnle o is arranged above the refrigerating pipes s, which are arranged in two groups on each side of the car and end above 'the ice receptacle. Into said reccptacle lead the pressure pipe 12, common to the pumps Z andll and th'e`overflow pipe cn.. The. pump l is a centrifugal pump driven from 'the wheel axle and `provided with straight vanes in. order that it may rotate in either direction.
VThe pumpi'l1 ismotordriven and is used when the car is Posting in a station'or such like. which by means of suitable coiiplings can he coupled to the'whecl axle or to L motor, as desired.
The strainer receptacle o is shown in detail in Figs. 3 4.
As .described above the'two pipas 12 and abnt mto the said receptacle.
Between f course onlv 'one pump may be used,
said pipes the strainer t is arranged, for
instance in' the manner shown, so that the Arefrigerating liquid, when arriving from the pumps through the pressure pipe l2 Will 5 have to pass the strainer t. Under normal conditions, however, the liquid` after having passed the stiainer, will How through the pipe .sl tothe refrigerating pipes said pipe sl ending in the bottom of the receplo tacle 0 in a chamber, separated from the. other part of the receptacle by means of the partition v e The mouth ot' the pipe .sl is provided with a Valve o, which is normally held open by a suitable'thermostat w, so that the liquid will have free access to the refrigerating pipes. If. however, the temperature should fall below the predetcrmined minimum, the thermostat Will act upon the xalre o so that `it closes` the pipe s', ivhereby the liquid will fill the receptacle up to the mouth of the over-How pipe n, the surplus of liquid'flowiing back to the pump. By arranging this Way the valve ir can be easily inspected and cleaned.
w is a pipe with a Valve 11/, which pipe is used when the receptacle o is to be cleaned, whereby a Water-jet is forced into the receptacle o inside the strainer. the xvater escaping through -the pipe w.
z is a cover on the receptacle o.
Having now described and ascertained the nature of my said invention, what I claim and desire to secure by Letters Patent is 1. In a refrigerating apparatus comprising in combination a refrigerating member, an ice receptacle ivith Which the said member is connected, and a pump for causing a refrigerating liquid to circulate through the said member and receptacle` a strainer for the said liquid arrunged at the upper end of the pump pressure pipe and located above the said retrigt :itiug member.
2. In a refrigerating' apparatus comprising in combination `a retrigerating member, an ice receptacle with Which the said member is connected, and a pump for causl ing a refrigerating liquid to circulate. through the said member and receptacle, a strainer receptacle containing a strainer, the said rcceptacle iming arranged between the ice receptacle and the refrigerating member and located above the said refrigerating member` the said strainer dividinr the 55 straincr receptacl'e in two conusiartments.
into one of which leads `the pressure pipe from the pump, While the other communicates with the refrigerating member.
3. In a refrigerating apparatus comprising in combination a refrigerating member, an ice receptacle With which the said member is connected, and a pump for causing a refrigerating liquid to circulate through the said member and receptacle, a strainer receptacle containing a strainer, the said re.- ceptacle being arranged between the ice receptacle and the refrigerating member and located above the said refrigerating meplbeithe said strainer dividing the strainer receptacle in two compartments into one of which leads the pressure pipe from the pump while the other communieates with the refrigerating member and by means of un overflow pipe with the pump.
4. In a refrigerating apparatus comprisiug in combination a refrigerating member, an ice receptacle with Which the said member is connected, and a pump for causing a refrigerating liquid to circulate through the said member and receptacle, a strainer receptacle containing a strainer, the said receptacle being arranged between the ice receptacle and the refrigerating member and located above the said refrigerating member, the said strainer dividing the strainei` receptacle in two compartments into one of which leads the pressure pipe.V from the pump While the other communicateasI with the refrigerating member lby means of a pipe, provided with a Valve' operated by a thermostat.
In a refrigerating apparatus eomprising in combination a refrigerating member, an ice receptacleiwith which the said member is connected, and a pump for ca'using a refrigerating liquid to circulate through the said member and receptacle, a strainer re ceptacle containing a strair the said receptacle being arranged beto een the ice'receptacle and the refrigerating member and located above the said refrigerating member, the said strainer dividing the strainer receptacle in two compartments into one. of which leads the pressure pipe from the pump While the other communicates with the refrigerating member by means of a pipe provided with a `calve operated by a thermostat and further communicating With the pump by means of an overfiow pipe.
