generally improve and simplify the construction of refrigerating, systems of the typeset forth, to such an extent that they.
can be manufactured at a very reasonable cost and will possess so few working parts that there is practically no liability of failure to function pro er y.
In carrying out t e above end, a further object is tosupply the system with a osltive, inexpensive, automatic control wich is based entirelyon time and does-not rely for its operation upon delicate and complicated thermostats, pressure-operated controls and similar devices, which are liable to cause trouble. 7
A still further object is to discharge any excess pressure of refrigerant into a llquld waste pipe which usual so thatno obnoxious odors will exist m the vicinity of the system, should the latter blow ofi. I
With the foregoing in view, the invent on resides in the novel subject matter hereinafter described and claimed, the descr1pt 1on being supplemented by the accompanying drawings.

Fi ure 2 is a view slmilar to "Fig. 1 but showing the twin type of system in which two combined generators andabsorbers are employed.

tion through one of the magnetically opened valves Whlch are used to admit cooling liquid into cooling coils or the like associated with the generating and absorbing tank or tanks and a combined gas condensing and liquid collecting tank which is also employed.
In the form of construction shown 1n Flg. 1, the numeral 1 designates a combined generating and absorbing tank which may be of cooling "liquid.

form and with a coil or the like 3 which is adapted to circulate water or some other Liquid su- 'l i in 4--4 leads to the coil 3 from s m ain ligui supply pipe 5, andsaid pipin 4+4 is provided with a normally close magnetically opened valve 6. The coil 3 discharges into a liquid waste pipe 7.-
Disposed at an suitable location with respect to the ta 1, is a gas condensing and liquid containin tank 8,.and gasv conducting means 9, lea%s from the up er end of said tank 1 to the upper end of t e tank 8, said gas conducting means' includin'g a check valve 10 whic'h opens away from the tank 1, and also embodying anjai'r-cooled rectifying coil llvwhich serves to condense any water vapor which may rise with the generated gases from'the tank 1 Within the combined gas condensing and liquid 'retaming tank 8, wehave shown a coolmg coil 12 which is connectedby iping 13-13', with the main. -liquid supp y pipe 5, said piping 1313 having a normally closed- -magnetica'lly opened valve 14. The coil 12 discharges into the waste pi e 7, and we have also shown a pressure-discharge pipe 15 leading to said Waste pipe from a pressure blow-off valve 16 for the refrigerant circulating means. In the resent showing, the
valve 16 is connected with a ipe 17 which may well extend from a portion of the gas conducting means 9, or may otherwise communlcate with the interior ofthe system.
Upon the pipe 17, a suitable purge valve 18' has been illustrated.
At 19, an expansion coil has been shown which is adafted to be located in any chamber to be re rigerated, such as a brine tank 20. Leadin from the lower end of the tank 8, to the 001 19, is a pipe 21 having an appropriate expansion valve or the like 22', while leadinfg fro-m said coil 19 into the lower end 0 the combined generating and absorbing tank 1, is a pipe 23 which is provided with a check valve 24 which opens toward said tank 1.
Current supply wiring is provided for the heater 2 and the magnets of the valves 6 and 14, said wiring having independent circuits of the frigerant evaporates changing for said heater and valves, controlled b normally 0 en switches 25, 26 and 27 an constantly riven means are provided for closing these switches in proper sequence, holdthem closed for, apredetermined interva tion may be varied if desired.
Assuming that the system has been purged of air to the proper extent, and that an adequate quantity of the refrigerating solution has been placed in the tank 1, the operation system is as follows: The am"29 closes the switch 25 and thus brings the heater 2 into operation for a predetermined len h of time so as to generate gas in the tan 1. This enerated gas passes to the tank 8 and by t e time as; as reaches this tank, the cam 30 has clos t e switch 26, so that the valve 14 is opened and cooling liquid flows through the coil 12 and out thewaste pipe 7.' Thus, the gas entering the tank 8 1s promptly condensed to a liquid and the liquid collects in the lower end of said tank. At a suitable time after opening of the valve 14, the cam' 29 permits the switch 25- to open and throws the heater 2 out of play. Then, after the cam 30 permits the, switch 26 to open and effects closing of the valve 14, the
cam 31 closes the switch 27 and thus 0 ens the valve 6 for the-coil 3. Now, the coo ing liquid passing throu h the coil 3 chills'the hquid remaining in t e tank 1 and produces a partial vacuum in this tank, as well as in 23, coil 19 and pipe 21. This vactank 8, through the expanslon valve 22, into the expansion coil 19, where the liquid reits state to a gas or vapor, there y producing refrigeration. gas or vapor then passes through the check valve 24 and pipe 23, into the tank 1,- sothat it a ain mixes with the liquid which has remained in said last named tank.
as into the liquid waste pipe 7 to be carried y the latter to a sewer or to some other point remote from the apparatus, so that the system of extreme simplicity there will be no obnoxious fumes around the latter.
In the twin type of construction shown in Fig. 2, thenumerals 1 designate a pair of tanks corresponding to the tank 1, eachof said tanks 1'5 having its own electric heater 2" andcooling coil 3, vthese coils bein connected' by piping 4 with a cooling quid supply line 5, said piping 4"- having normally-closed magnetically-opened valves 6". At 7 is shown a waste pipe into which the coils-3" discharge.
- 8 indicates a combined gas condenser and liquid collectin tank which is shown horizontally instea of vertically, but ma be in elther ofthese positions or in any ot er position desired. Gas conductin means 9 leads to the tank 8 from the tan 1 and is provided with a check valve 10" and a rectifying coil 11 for each of said tanks .1. Within the tank 8*} is a cooling coil 12 connected by piping 13 with thecooling liquid suplply pipe 5, said piping'13 having a norma y-c osed magnetically-openedvalve 14".
The coil 12='discharges into the waste ipe 7, and at 15, 16, 17 and 18" arts have een shown which correspond to t e parts 15, 16, 17 and 18 of Fig. 1.
'19" designates an expansion coil connected by piping 21 with the lower portion of the tank 8. and provided with an expansion valve'22. -Return piping 23 is rovided from'the coil 19 to t e ower en s of the tanks 1, and this return piping is provided with check valves24. Separate circuits are provided for each of the heaters 2" and for each of the magnetic valves' 6 and 14, each circuit having its own individual switch. At 35 and 36, are shown the switches for the two heaters 2"; 37 designates the switch for the valve 14; and 38 and 39 refer to the switches for the two. valves .6. These switches are controlled b cams 29 on a rotary drum 2 8 which is riven in the same manner as the drum 28, and the relation of cams is such that when one of the tanks 1 is being heated, the other tank 1 is bein cooled by circulation of cooling liqui through its coil 3. Thus, pressure is exerted 'on one. side of the system and suction on the other side, which roduces unusually advantageous results in awing the refrigerant through the s stem. The arrangement of cams is also suc' that the valve 14 will be opened as soon as either of the tanks 1 starts to generate gas, said valve 14 being closed however between the intervals of-generation so as to conserve water or other cooling liquid which may be used.
It will be seen from the foregoing that a has been provided, yet one which be highly efiicient and reliable and is free from a great number of intricate and expensive movable parts which are commonly used. The invention is therefore particularly adapted for home refrigerating Elants, but is by no means restricted to t is particular field of use,
Obviousl any desired wirin maybe employed, and the current controlIing switches, as wellas the magnetically-opened valves for the cooling liquid, may be of an preferred design. Probably the most a vantageous constructions for switches and .valves, is shown in Figs. '3, 4, and 5, and as such constructions will be well understood by anyone skilled in the art, without a descrip-L tion, such description is not herein 'furmshed." c r As excellent results are obtainable from the 'general construction and association shown, such construction and'association are preferably followed. However, within the scope of the invention as claimed, numerous modifications maybe made. If desired, instead of using an expansion valve, expansion:
can be accom lished by using what is known as the floo ed system, the principles of which are known tothose skilled in the art.
We claim: i v1. An intermittent absorption refrigerating system comprising circulating means. for
the refrigeranaincluding electrical heating means and valveeco'ntrolled cooling means,-
