wall of the box: of ;Fig.,- l;-and Fig. 3 is. a top-*planview of divided by a generally-vertical partition denoted end walls of the-box ia'tndislocated somewhat nearer to the end walla-than to the end wall-5,.

and which extends fromthe.topi downwardly approximately one-half the height oi. the .-,bcx. v

The partition -Ill is bent at approximately'its' mid-paint to provide a centerportion 12 which v is inclined downwardlyand toward the end wall 5fto a point spaced slightly above theflbottorn l, i from which point the partitionis turned 'downwardly to the bottom of the box to provide the lower vertical partllof the partition. A horizontal partition H connects-the partition land the end wal13', it" being connected to partition III I at approximately the upper end of "the inclined part I2 thereof. The partitions l0 and and the end wall 3 thus definean upper chamber l5 within which a radio transmitter maybe placed andalower chamber l6 within which a pressure responsive apparatus II may-be placed. .The

when they could be seen, itiwas very diflicult to partition Ill and the end wallii also include between them approximately'one-half of the box,-

- which is wide atthe upper part thereof, between the end'wall 5 andthe uppervertieal part- II of the partition and which isnarrow' at its lower part between the end wall'5 and'the ,l'o'wer'ver tical part 13 of partition Ill; The part of the box between partition") and end wall 5 is pari 'tially divided by a partition 20 which is'paralleltothe end walls ofthe box and-approximately midway between the end wall 5 and" the upper vertical part of partition to, extending downwardly from the top 2 a distance or approxipart of the partitions l3 and 20 are in the same plane and are separated by a considerable space 26, inasmuch as the lower end of partition 2|! is substantially above the upper end of partition it. Thus, the upper part of the space between the partition II and end wall I is divided into two vertical'passages 26 and 21, the former being located between end wall 6 and partition 26 and the latter being located between partition 26 and the upper vertical part II of partition II. The lower part of the space between end wall 6 and partition ll forms a passage 26 which is equal in area to the space betweenend wall 6 and partition 26 because of the positioning of partition II in the plane of partition 20.

The partition 26 provides a support for a tem-' perature-responsive device 36 which is disposed in passage 26 between the partition 20 and end wall 5. The partition 26 and partition part It form supports for the upper and lower ends, respectively, of a humidity-responsive device 3| which is disposed within the

passages

26 and 28. Thus. the temperature and humidity devices 36, II are so disposed that they extend over or in front of the space 25 between the partition 26 and the co-planar partition part l3. The 'parti-' tion 20 also provides a support for a resistancevarying device 32 which is operated by the humidiiy responsive element 3|, and which is disposed in the passage 21, being mounted on the side of partition 20 opposite to that onwhich the humidity and temperature-responsive devices are mounted.

Means are provided by the invention for causing an increased flow of air through the part of the box between the end wall and the partition 10. Such means comprise three openings in the box, for each of which closures are provided, whereby the openings may be uncovered when the box is in use or may be covered otherwise. Opening 40 is located in the top 2 of the box and is defined by end wall 5,.partition 26 and the side walls of the box, a cover 41 being provided for this opening and being hinged along one side thereof to the top of end wall 5. This opening communicates the passage 26 to the outside of the box. Passage 21. between partition and upper vertical part I l of partition I0 is communicated to the outside of the box by an opening 42 in the top of the box, a cover 43 being provided for this opening, the same being hinged along one side thereof to the top 2. The passage 26 is communicated to the outside of the box by an opening 45 in the bottom of the box, this opening being adapted to be closed by a flap 46 which is hinged along one side thereof to the bottom of the end wall 5. Each of the flaps or closures 4|, 43. 46 is provided with a string whereby it may be tied in open or closed position, anchors 56 being provided in suitable places on the outside of the box towhich the strings may be tied.

When the radiometeorograph is not in use the box will be completely closed by tying all of the flaps over the corresponding openings. when the device is to be used, allof the openings are partition ll laterally through or across the temperature and humidity elements to passage 26 and opening 46. The temperature and humidity elements will therefore be subjected to two streams of air flowing in different directions.

' parts of the temperature and humidity-responsive elements. The strips forming the grid are preferably made of as great depth as is permitted by the spacing of .the upper ends of the temperature and humidity elements from the top of the box and the grid is preferably made c0- extensive with the passage 26. It will be seen that this grid will prevent the rays of the sun from reaching the temperature and humidity elements except in the rare case when the sun is in the exact prolongation of the center-lines of the

passages

26 and 28.

There is also provided by the present invention improved means for examining the inside vof the box and, while doing so, making adjustments of the meteorograph elements therein. Such means are disclosed in Fig. 2 of the drawing and comprise openings 60, 6| and 62 which are provided in that part of the end wall 3 of the box which encloses the lower chamber 16 within which the pressure element l! is located. Opening 60 is preferably oval in shape with its major dimension transverse to the end of the box and is located in the center of the lower part of end wall 3. Opening 6| is preferably circular in shape and may be located a short distance above the opening 60. Opening 62 is preferably U-shaped and may be located a short distance to the side of opening 60. Means are provided for covering all of these openings. A transparent covering of glass or other material 64 is permanently placed over opening 60 and is held in place by rivets 10. One part, preferably a half, of this covering is magnifying in nature although the entire covering may be so, if desired. Means are provided for closing the opening 6| which is preferably located above the magnifying part of the viewing opening 60, such means comprising a button 66 which is formed on one end of a strip 61, the other end of which is attached to the box, as by a rivet about which the button 66 and strip 61 may be swung in order to uncover the opening 6!. The opening 62 is defined by a score line in the material of the box and is normally closed, being opened by punching in the material defined by the bottom of the' U-shaped i score, which is then hinged to the box wall by uncovered by tying the flaps in open position.

being deflected therefrom by inclined part l2 of the straight upper edge thereof.

When the box is in its normal use all of the openings are closed. If it is desired to view the pressure element which is inside the box it is only necessary to look through the glass 64. As onehalf of the glass is magnifying in nature the smallest parts of the pressure element may be clearly viewed. If desired, a light may be caused to shine through the other side of the glass in order to illuminate the interior of the chamber. If it is desired to adjust the pressure element, it

The amount of air will thus be increased and the is only necessary to remove the coverings from the openings 60 and GI in order to insert the necessary instruments.

While I have described and illustrated only one embodiment of my invention, it will be ap parent to those skilled in the art that other embodiments may be made without departing in any way from the spirit or scope of the invention, for the limits of which reference must be had to the appended claims.
