Referring now to the drawings, wherein I have shown one form of construction embodying 4 the invention, there is a compartment I open at the top. This compartment may be used as a room or for a bed or for any other suitable constfuction or for any other suitable purpose where one or more people may be received; It may be 45 made out of any suitable material, preferably heat insulating material. I have illustrated it as made of cloth so that it may be easily manipulated, but it may be made of any other suitable material. * In the construction shown the walls of the compartment preferably consist of two members 2 and 3 separated by an air space 4. When the walls are made of flexible material there is provided at the upper portion of the end walls the rigid members 5 and Sa 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 material, is to insert them in the loop of the material, as shown for example in Fig. 4. There may be similar 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 cooling device. As showing one means for doing this, there are at the opposite ends the supports 6 and 7. Associated with these supports and preferably on the interior thereof, are the flexible members 8 and 9 which pass over suitable direction changing devices 10 and II and which are connected to the upper part of the receptacle in any suitable manner, as by being connected to the rigid 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 12 and 13.

These springs are fastened at their lower ends 14 and 15 to a fixed part.

The cooling element 16 may be supported in any desired manner, as by being connected to a support 16a. This cooling element is herein shown as provided with means for circulating a cooling material or refrigerant therethrough so as to cool the air coming in contact therewith. Any of the usual refrigerating apparatus may be used, and this apparatus may be located in the casing 18. The supports 16a are preferably connected with the refrigerating apparatus and are hollow so'that the refrigerant passing to the cooling element 16 may pass up through the hollow support 16a.

The cooling element is preferably provided with some means for catching the condensed moisture.

As herein shown, the cooling element is provided with a liquid receiving receptacle 19 for receiving the moisture condensed by the cooling element.

This receptacle preferably encloses the coil, but is open at the top 20 for the admission of the air, and has a- discharge opening 21 through which the cooled air passes into the compartment.

There is preferably a moisture receiving member 22 upon which the water is received from the cooling element, the water passing therealong and then into the bottom of the compartment, see Fig. 4. The member 22 prevents noise due to the dropping of water into a body of water, and also directs the cooled air out through the opening 21 and prevents it from coming into contact with the water in the compartment, and also tends to keep the water from freezing..

Some means is provided for adjusting the cooling element and the top of the compartment relatively so that the cooling element may be made to project varying distances into the compartment to regulate the temperature of such compartment. When the compartment, for example, is made of rigid material it may be preferable to move the cooling element so that it may project more or less into the compartment. Any suitable means for this. purpose may be used, and I have illustrated one means which consists in raising or lowering the support 6 so as.to raise or lower the T6 cooling element, One construction, which I have shown for purposes of illustration, consists in providing a rack 23 attached to the casing 18 and which engages a gear 24 on a shaft 25, which shaft has the worm gear 26 which engages a worm 27 on the shaft 28, operated in any suitable manner, as by means of the handle 29. These gears and the housing are supported upon supports 30 on opposite sides of the casing 18, there being guiding members 31 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. When it is desired to lower the cooling element the handle is moved in the opposite direction, which causes the casing 18 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 construction the cooling element may be moved with relation to the top of the compartment so as to provide any desirable relation between them. Instead of moving the cooling element I may move 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 is of flexible material and is supported by the flexible supports 8 passing over the direction changing devices 10 and 11. When it is desired to hold the top of the compartment in any desired position, there is removably attached to the 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 supports. This holding member engages a stop or part 33 fixed with relation to the direction 3 changing devices 10 and 11. It may be the hood for such direction changing devices or any other suitable part.

When the holding member is attached to the flexible member 8 and is then released, the resisting device 12 pulls on the flexible member and moves the holding member up Into engagement with the stop 33 which prevents further movement and holds the top of the compartment in position. When it is desired to adjust the top of the compartment, the top of the compartment is moved downwardly, for exampl from the omtposition shown in Fig. 7, and the holding device connected with the flexible member 8 at the desired distance above the top of the compartment. This will then hold the top of the compartment in any of its adjusted positions, one of which adjusted positions is illustrated in Fig. 1.

I have shown the holding member 32 simply for purposes of illustration, and I may provide means whereby any person in the compartment or in the bed can, by simply pulling a cord, lower the top of the compartment and then fasten the cord to hold it in its lowered position. The cord may be let out to adjust the top of the compart- co ment in any of its intermediate positions. This cord 32a may for example, be attached to the holding device 32 or any other suitable limiting device, and may then pass down over a direction changing device 32b and then to any point properly 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 connect the cord with the holding device 32-c. When it is desired to adjust the other end of the compartment, this may be done by a cord 32d which may also be fastened to the holding device 32c.

It will thus be seen that the cooling element and the top of the compartment may be adjusted relatively by moving either the cooling element o0 the top of the compartment.

In Fig. 5 there is illustrated a modified con. struction of the cooling element. In this con. struction there are a plurality of cooling element 34 and 35. The cooling element 34 has a casing 36 with an air admission opening 37 into which the air passes, and a discharge opening 38 out of which the cooled air passes to the compartment The cooling element 35 has an air admission opening 39 lower down than the air admission opening 37 through which air passes to the cooling element, the air being discharged through the discharge opening 40 into the compartment. There is preferably a water receptacle 41 and the inclined water engaging members 42 and 43 which direct the water into the bottom of the water receptacle. With the construction shown in Fig. 5 a portion of the air being cooled may be taken 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 position of the cooling elements and the upper part of the compartment the proportion of air taken from outside of the compartment and from inside the compartment may be varied. When the, device, for example, is in the position shown in Fig. 5 all the air contacting with the cooling element 34 comes from outside the compartment, whereas a portion of the air contacting with cooling element 35 comes from outside the compartment and another portion from inside the compartment. By changing the relative position of the 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 from inside the compartment for contacting with cooling element 34, thereby regulating the temperature in the compartment.

Some means Is provided for taking the water out of the receptacles 19 and 41, and this may be accomplished by providing them with an outlet 44 having a controlling valve 45. This device would be placed in all of the water receptacles.

In Figures 10 and 17 I have shown a modified construction wherein the wall of the compartment, instead of being made of flexible material, is made in sections, the upper portions of the sections being slidable up and down and beingpreferably 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 suitable support 47. The refrigerating apparatus for the refrigerant used in the cooling device may be located in the casing 47a. This cooling element may be movable up and down, as shown for example in ig. 1, or in any other manner and it is arranged so that it will cool air and drop it by gravity into the compartment. In this case the compartment is made up of a series of sections 48, which are preferably removably connected together so that the compartment may be easily and quickly assembled or removed.

These sections, as herein shown, are provided with side frame members 49 and 50 and a bottom member 51. At the bottom there are the two separated wall members 52 and 53, preferably of heat insulating material, with a space 54 between them. The upper part of the sections consists preferably of a transparent member 55, as for example of glass, although of course it may not be transparent if it is desired to have it of any other material.

r Some means is provided for moving the upper section 55 up and down so as to lower or raise Sthe upper edge of the compartment. In the particular construction shown this member 55 is s raised and lowered by means of a handle 56 on the Sinside of the compartment. This handle is connected by suitable gears 57 with the toothed portion 58 which is connected to a shaft 59. ConSnected with this shaft is an arm 60 which has a pin 61 which works in a slot 62 in the member 63 Spreferably attached to the bottom of the member 55. It will be seen that by rotating the handle 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 50 acting as guides therefor. This upper member 55 may be moved down into the space 54 between the side members 52 and 53.

The sections 46 are fastened together in any desired manner. As shown for example in Pig. 16, their edges are brought into proximity and are preferably provided with a packing member 64 between them, and are then fastened together by fastening devices 65, which may be bolts as indicated in Pigs. 16 and 17.

At the corners I may provide an angle member 66 which is fastened to the two corner sections by suitable fastening devices 67, and there may be a piece 68 fitting into the angle member and fastened thereto by the fastening devices 69, see Fig. 16. The several sections may be fastened together so as to form the compartment, as illustrated in Pigs. 10, 11 and 12, and this compartment may be of any size desired and any use desired.

I have illustrated one use of such compartment wherein there is a desk 70 and chairs 71, as for example when it would be used in an office. It is of course understood that it can be used for any purpose desired. One or more of the sections may be hinged so as to form a door 72 to permit people to readily pass into and out of the compartment. These sections when fastened together may simply rest upon the floor or other support.

If desired, there may be provided a suitable fastening means for holding them in place, and there is shown a simple fastening means in Fig. 15, which consists of the member 73 which is attached to the section and which may be attached to the support by suitable fastening devices 74.

These compartments, of course, can be used out 60 of doors if desired, in which event it would be desirable to have some kind of a roof over them to keep out the rain and sun. This roof-might simply be a piece of canvas or any other arrangement might be used. It will be seen that by varying the height of 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 as' 80 the cubical contents of the compartment decreases, and being higher as the cubical contents increases. It will further be noted that the upper edge of the compartment shown in Figures 1 to 8 can be moved down and can be held in this down position by the holding devices 32 and 32c so that when a bed is in the compartment the bed can be easily made up.

I have described in detail particular construe- 70 tions embodying, the invention, but it is of course evident the constructions may be varied in many particulars, and some parts omitted and others added, without departing from the spirit of the invention as embodied in the claims hereto appended, 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 bottom portion of the compartment. When it is desired to regulate the temperature in the compartment, the top of the compartment and the cooling element are moved relatively, either by moving the cooling element or the top of the compartment.

If the cooling element, shown for example in Fig. 7, is moved down into the compartment, it will be seen that air from-the compartment passes into contact with the cooling element and is then 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 compartment may be brought to a lower temperature.

If it is desired to raise the temperature of the air in the compartment, the top of the compartment and the cooling element may be adjusted relatively, as shown in either Figs. 1 or 8, in which position the admission opening for the air e i passing to the cooling element is above the top of the compartment, thus taking all the air from outsidethe compartment and cooling it and dropping it in t to the compartment.

When the device is in operation, the outside air will be warmer than the air inside the compartment, and it will be seen that by taking this warmer outside air and cooling it, the temperature in the compartment will be raised, that is, it will not be as low as when the air is 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 tha thatn that shown by the adjustment 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 compartment and a part of the air comes from inside the compartment, thus producing a temperature in the compartment which will be somewhere 60 intermediate the temperature when the parts are in the position shown in Figs. 7 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 element 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 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 proper adjustment of the parts.

In Figure 5 there is illustrated a construction *here a greater range of temperature may be secured, as in addition to providing means for taking all of the air outside of the compartment it gives a longer range where air may be taker both from outside the compartment and from inside the compartment. When this construction i! moved completely down into the compartment all the air will be taken from inside the compart ment. It will further be seen that when the cool ing element is up above the top of the compartment a sufficient height, all the air that is cooled is taken from outside the compartment and dropped into the compartment and displaceswarmer 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 compartment, and some of the air cooled is taken from inside the compartment, there will be less spillage 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 devices 32, so that any person within the compartment can look out 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 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 th stionse sections may be moved clear down so as 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 compartment can converse and do business with people on the outside just the same as if the compartment 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 cooling effect still be secured as efficiently as if they 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 apparatus and without the use of any regulating instruments.

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 compartment and displace warmer air and cause this warmer air to rise and spill out over the spillage edge, with means for changing the relative position of the cooling element and spillage edge to regulate the temperature in the compartment.
