Refgrnng now to the drawings’ Flg- 1 is a Side View and elevatfon Showing One form 0f device _embodying the Invention; Fig. 2 is a view showing the upper part of Fig. u 1 with the parts in a diñ‘erent position; _ «' ' ' 5o In the construction shown the walls of the com partment preferably consist of two members 2 and 3 separated by an air space 4. When -the walls are made of flexible material there is pro - vided at the upper portion of the ehd walls the u ~ 2,134,003 2 rigid members ‘5 and 5a which extend crosswise thereof. These rigid members may be fastened in position in any desired manner, and a simple manner, if the walls are made of flexible mate rial, is to insert them in the loop of the mate rial, as shown for example in Fig. 4. There may be vsimilar rigid members 5c located at the sides of the compartment. ' Some suitable means is provided for supporting the walls of the compartment> when it is made of flexible material, and also for supporting the cool ing device. As showing one means for doing this, there are at the opposite ends the supports 6 and 1. Associated with these supports and preferably 15 on the interior thereof, are the flexible members 8 and 9 which pass over suitable directionchang ing devices I0 and II and which are connected to the upper part of the receptacle in any suit able manner, as by being connected to the rigid> 20 members 5 and 5a. The other ends of the flexible members are, connected with a resisting device, such as a weight or spring. I have illustrated them as being connected to the springs I2 and I3. These springs are fastened at their lower ends I4' 25 and I5 to a ñxed part. The cooling element I6 may be supported in any desired manner, as by being connected to a support I6a. manner, as by means of 'the handle 29,. These gears and the housing are supported lupon'su'p ports 30 on opposite sides of the casing I8, there being guiding members 3I on the casing which slide along the supports 30. When it is desired to raise the cooling element the handle 29 is turned so as to move the casing and the support 6 upwardly, as shown for example in Fig. 8. The Worm and Worm wheel act as a lock to hold the parts in any position when. the handle is released. 10 When it is desired to lower the cooling element the handle is moved'in the opposite direction, which causes the casing I8 and the support 6 to be lowered, as for example to the position shown in Fig. ‘7. , » ‘ " It will be seen that by means of this construc tion the cooling element may be moved with rela tion to the top of the compartment so asyto pro vide any desirable relationv between them. In stead of moving the cooling element I may move 20 the top of the compartment so as to secure the relative adjustment between the cooling element and the compartment. Any suitable means for accomplishing this result may be used. In the particular construction shown the compartment 25 is of flexible material and is supported by the Yflexible supports 8 passing over the direction This cooling element is herein shown as provided with means for circulating a changing devices IIi‘ and II. When it is desired ‘ to hold the top of the compartment in' any de siredV position, there is removably attached to the 30 flexible member 8 a holding member 32, which in this instance consists of a removable split ring extending through one of the links of the flexible I8. The supports Ilia are preferably connected ` supports. This holding member engages a stop or part 33 fixed with relation to the direction 35 with the refrigerating apparatus and are hollow changing devices I0 and II. It may be the hood so'that the refrigerant passing to the cooling ele -ment I6 may pass up through’the hollow support for such direction'changing devices or any other suitable part. l ISa. when the holding member' is attached to the _ The cooling element is preferably provided with flexible member 8 and is thenv released, the re 40 40 some means for catching the condensed moisture.

Any of the usual refrigerating apparatus may be used, and this apparatus may be located in the casing l partment. When the compartment, for example, .- `is made of rigid material it may be preferable to 65` move the cooling element so that it may project moreor less'intov the compartment. Any suitable meansff'or thispurpose may be used, and I have ¿illustrated _one'meansvwhich consists in raising or » lowering ,thesupport'ß so asto raise or lower the device, and may then pass down over a direction changing device 32b and then to any point prop 65 erly accessible to a party in the compartment. If the compartment has a bed in it for example, it may run to the head of the bed, and when the top is properly adjusted the occupant may con- , nect the cord with the holding device 32 c. When it is desired to adjust the other end of the com partment, this may be done by a cord 32d which providing a rack 23 attached to the casing I8 andv may also be fastened to the holding device 32e. whichengages a gear 24 Aon a shaft 25, which It will thus be seen that the cooling element and shaft has the worm gear 26 which engages a the top of the compartment may be adjusted rel cooling element. One construction, which I have shown for purposes of illustration, consists in 75 worm 21 on theshaft 28, operated in any suitable \ 76 3" 2,134,003 ` atively by moving either the cooling element or the top of the compartment. - . - Some .means is provided for moving the upper section 55 up andndown so as to lower or raise the upper edge of the compartment. In the par struction of the cooling element. In this con ticular construction shown this member 55 is struction there are a plurality of cooling elements -raised and lowered by means of a handle 56 on the 34 and 35. The cooling element 34 .has acasing inside of the compartment. This handle is con 36 with an air admission opening 31 into which nected by suitable gears 51 with the toothed por the air passes, and a discharge opening 38 out of V tion 58 which is connected to a shaft 59. Con which the cooled air passes to the- compartment. 10 'I'he cooling element l35- has an air admission nected with this shaft is an arm 60 which has a pin 6l which works in a slot 62 in the member 63 '. opening 39 .lower down than thel air admission preferably attached ._to the bottom of the member opening 31 through which air passes to the cool 55. It will be seen that by’ rotating the handle In Fig. 5 there is illustrated a modiñed con ing element, the air being discharged through the discharge opening 40 into the compartment. 15 There is preferably a water receptacle 4| and the inclined water engaging members 42 and 43 which direct the water into the bottom of the water re ceptacle. With th'e construction shown in Fig. 5 a portion of the air being cooled may be taken 20 from outside of the compartment and another portion taken from inside the compartment, both portions being discharged into the compartment. It will be seen that by' changing the relative po sition of the cooling elements and the upper part 25 of the compartment the proportion of air taken from outside of the compartment and from inside the compartment may be varied. When thek de vice, for example, is in the position shown in Fig. 56 the arm 60 will be moved up and down so as to move the member 55 up and down, the side frame pieces 49 and 56 acting as guides therefor. 15 'I'his upper member 55 may be moved down into the space 54 between thev side members 52 and 53. 'I'he sections 48 are fastened together in any de sired manner. As shown for example in Fig. 16, their edges are brought 'into proximity and are 20 preferably provided with a packing member 64 between them, and are then fastened together by fastening devices S5, which may be bolts as in dicated in Figs. 16 and 17. - At the corners I may provide an angle member 25 66 which is- fastened to the two corner sections by suitable fastening devices 51, and there may be a piece 63 fitting intoV the angle member and 5 all the air contacting with the cooling element ’ .fastened thereto by the fastening devices 59, see 34 comes from outside' the compartment, where as a portion of the air contacting with cooling element 35. comes from outside the compartment and another portion from inside the compart ment. By changing the relative position of the 35 upper part of the compartment and the cooling elements it will be seen that more or less air may be taken from outside the compartment and Fig. 16. The several sections may be fastened to gether so as to form' the compartment, as illus trated in Figs. 10, 11 and 12, and this compart ment may be of~anyl size desired and any use desired. , . I have illustrated one use of such compartment 35 wherein there is a- desk 10 and chairs 1I, as for example when it would be used in an oiiice. It , from inside the --compartment for contacting with is of \course understood that it can be’used _for cooling element 34, thereby regulating thevtem- g any purpose desired. One or more of the sections 40 perature in the compartment. may be hinged so as to form a door 12 to permit Some means is provided for taking the water people to readily pass into and out of the com- 40 out ofthe receptacles I9 and 4l, and this may be partment. These sections` when fastened together accomplished by providing them with an outlet may simply rest upon the floor or other support. 44 having a controlling valve 45. This device If desired, there may be provided a suitable fas 45 would be placed in all of the water receptacles. tening means for holding them in place, and there ‘ In Figures 10 and 17 I have shown a modiñed is shown a simple fastening means in Fig. 15, construction wherein the wall of the compart which consists of the member 13 which is at ment, instead of lbeing made of _ñexible material, is made in sections, the upper portions of the 50 sections being slidable up and down and beingM Apreferably made of transparent material such as glass. In this construction there is illustrated a cooling element 46 which may be of any suitable construction and which is supported by a suit 55 able support 41. The refrigerating apparatus for the refrigerant usedV in the cooling device may be located in the casing 41a. This cooling element may be movable up and down, as shown for ex ample in Fig. 1, or in any »other manner and it> oo is arranged sothat it will cool air and drop it by gravity into the compartment. In this case tachedto the section and which may be-attached Y to the support by suitable fastening devices 14. These compartments, of course, can be used out 50 ofI doors if desired, in which event it would be desirable to have some kind of a roof over them tofkeep out the rain and sun. This roofemight simply be a 'piece of canvas or any other ar rangement might be used. It will be seen that by varying the height of ' as the top of the compartment, and when necessary the height -of the cooling element, I can vary the cubical contents of the compartment to regulate the temperature, the temperature being lower asJ 00 ' the cubical contents of the compartment de the compartment is made up of a series of sec tions 48, which are preferably removably con- ' creases, and being higher as the,cubical contents nected together .so that the compartment may increases. lIt will further be noted that the upper 65 be easily and quickly assembled. or removed. edge of the compartment shown in Figures 1 to 8 These sections, as herein shown, are providedl can be moveddown 'and can be held in this down with side framemembers 49 and 50 and a bottom position by the _holding devices 32 and 32e so. member 5|. At the bottom there are the two that when a bed is in the compartment. the bed separated wall members 52 and 53, preferably of can be easily made up. ‘ y heat insulating material, with .a space 54 between I have described in detail particular construc them. The upper part of the sections consists tions embodying the invention, but it is of course I preferably of a transparent member 55, as for evident the constructions may be varied _in many example of glass, although _of course 'it may not- particulars, `and some parts omitted and others -be transparent if it is desired to have it of any added, 'without departing from the spirit of the other material. ' ‘ ' ' ._ inventi'on as embodied in the claims hereto ap y4 2,134,003 pended, and- I therefore do not limit myself to the particular construction shown. The_use and operation of my invention are as follows: When the device is in use, whether it is used in connection with a bed or an apartment or a room in which people are received, the refrigerant is passed through the cooling element and air is cooled and drops by gravity down into the bot 10 ltorn portion of the compartment. When it is desired to regulate the temperature in the com partment, the top of the compartment and the cooling element are moved relatively, either by moving the cooling element or the top of the 15 compartment. ` If the cooling element, shown for example in Fig. 7, is moved down into the compartment, it will be seen that air fromf'the compartment passes into contact with the cooling element and is then 20 discharged back into the compartment. It .will be seen that by this means the cooler air in the compartment is recooled, and thus air in the ccm partment may be brought to a lower temperature. If it is desired to raise the temperaturesof the air 25 in the compartment, thetop of the compartment and the cooling element may be adjusted rela tively, as shown in either Figs. 1 or 8, in which position the admission opening for the air pass ing to the cooling `element is above` the top of 30 the compartment, thus taking all the air from outside the compartment and cooling it and drop ping it into the compartment. When the device is in operation, the outside air will be warmer than the air inside the compart 35 ment, and it will be seen lthat by taking thisv warmer outside air and cooling it, the tempera ture in the compartment will be raised, that is, it will not be as low as when the airis taken from the compartment and recooled, as shown in Fig. '7. If it is desired to have a temperature higher than that shown by the adjustment of the parts in Fig. '7, and lower than that shown by the ad justment of the parts in Fig, 8, the top of the compartment and the cooling element may be adjusted so that a part of the air being cooled by the cooling element comes from outside the com partment and a part of the air comes from inside the compartment, thus producing a temperature in the compartment which- will be somewhere 50 intermediate they temperature when the parts are in the position shown in Figs, 'l or 8. It will be seen that by this means the temperature in the compartment may be varied and adjusted by adjusting the relative position of the cooling ele 55 ment and the top of the compartment, for when this adjustment is such that all of the air passing through the cooling element is taken from the compartment, which air is cooler than the air on the outside, the result will be a lowering of the 60 temperature in the compartment, and when all of the air being cooled is the warmer air taken from outside the compartment, the temperature in the compartment will be higher, and that any intermediate temperature' may be secured by a ' 65 proper adjustment of the parts. In Figure 5 there is illustrated a construction _where a greater range of temperature may be se cured, as in addition to providing means for tak ing all of the air outside of the compartment, 70 it gives" a longer range Where air may be taken ' both from outside the compartment and from in side the compartment.’ When this construction is moved completely down into the compartment, all the air will be taken from inside the compart 75 ment. It will further be seen that when the cool . ing element is up above the top of the compart ment a suiiicient height, all the air that is cooled is taken from outside the compartment and dropped into the compartment and displaces warmer air, the warmer air spilling out over the top. It will further be seen that by moving the parts relatively so that the cooling element is lowered with relation to the top of the compart ment, and some of the air cooled is taken from inside the compartment, there will be less spill age of air over the top of the-compartment, and this spillage over the top of the compartment will decrease as the cooling element is moved down into the compartment. ' It will be seen that when the device is used for other purposes than for a bed, the top of the compartment may be arranged or may be moved down and 'held in this position by the holding de vices 32, so- that any person within the compart ment can lookout over the top- and converse with people on the outside and still be in a cooled atmosphere. Such person may thus look out when sitting down or the device may be arranged so that he can look out only when standing up. In the construction shown in Figs. 10 to 17 the compartment is made of material which is not flexible, and it is made in sections which are removably connected together, and these sections may be independently moved up and down by means of the handles 56. It will be seen that this 30 gives a very easy and simple and efficient means of moving the upper edge of the compartment for the purpose of varying the temperature therein. Furthermore, with this device the upper elements of the sections may be moved clear down so as ~ Ll to make it unnecessary to dismantle the device when it is used in the winter time, for when these members are moved down, people in the compart ment can converse and do business with people on the outside just the same as if the compart 40 ment were not there. It will further be seen that with devices of this kind the windows in the room may be opened in the summer time and the cool ing effect still be secured as eiliciently as if they 45 were closed. By means of the arrangement herein shown the temperature of the air in the compartment may be easily and quickly regulated and varied without in any manner controlling or regulating the cooling element or the refrigerating appa 50 ratus'and without the use of any regulating in struments. ' - It will be seen that there is here provided a compartment having a spillage edge for the air, with a cooling element in proximity to this spillage edge which cools the air and causes it to drop by gravity into the lower part of the com partment and displace warmer air and cause this warmer air to rise and spill out over the spillage edge, with means for changing the relative posi 60 tion of the cooling element and spillage edge to regulate the temperature in the compartment.
