I “ _‘ . 1 A further objection to this prior art wall'icon this invention ‘will be apparent from the follow- ‘ struction is foundinthe fact that the wall ing description when taken in connection with 50 readily conducts heat from one side to the other‘ the accompanying drawing in’which:v so as to be a relativelydne?icient thermal in“ sulator. Thermal conduction through the wall Figxl is a plan perspective view of one form occurs by virtue of‘an air‘ circulation being set of wall construction of this invention compris up within the ‘space 16 by convection. Thus as ing an inner wall and an outer wall; Fig. 2‘is a perspective view of an elongated ?ex 55 suming the outer wall I 2 to be coldgand the inner 2,411,477 3 wall IIJ warm, air in the space I6 will flow down wardly across the wall I2 and upwardly across the inner wall II]. By virtue of this circulation of air the wall I9 is constantly cooled and con somewhat smaller in diameter than the tubes I8 so that the tubes I8a are relatively spaced verti cally within the space I6. Each tube I8a is positioned opposite the top of a row of bricks III tinuously draws heat by conduction from the in the outer wall I2, with every other tube I8a side I1, and, therefore, is always continuously being opposite the top of a row of blocks II in cooled to in turn cool the space adjacent thereto. the inner wall I0. The function of the tubes These objections in the above described wall I8a is similar in all respects to the tubes'IB de construction are overcome in the present inven tion by the insertion within the space I6 of ?ex 10 scribed in connection with Figs. 1 and 3 so that a further description of the tubes I8a is believed ible elongated tubular members or inserts I 8 to be unnecessary. ’ (Figs. 1 and 2). Each insert or tube I8 has The modi?ed form of wall construction in Fig. water repellant characteristics and may be com 5 is comprised‘ of horizontal rows of blocks 2|, posed of tar paper, of heavy paper or thin metal with each block being of the usual type having a with an asphalt coating, or of thin rust-proof metal. The tubes I8 are horizontally positioned 15 longitudinally extended groove 22 in the top and a longitudinally extended groove 23 in the bot in a vertically stacked relation within the space tom thereof. In building this wall construction I6 so as to extend longitudinally of the walls the lower groove 23 in one tier is positioned op Ill and I2, with this assembly of the tubes I8 posite an upper groove 22 in a next vertically ad being made during the building up of the wall 20 jacent block 2| so that the grooves 22 and 23 de construction. ?ne a space 24 which extends longitudinally The diameter of the tubes I8 relative to the with-in the wall. In the normal construction of width of the space I6 is such that the tubes are the wall in Fig. 5 the space 24 is entirely ?lled slightly ?attened as indicated at I9, and wedged in the space I6 between the walls II] and I2. By 25 with mortar I5 so that moisture is able to pass by capillary action from one side to the other virtue of this assembly of the tubes I 8 in the of the wall. To prevent this passage of mois wall construction the space I6 is divided into a ture through the wall a tube I8 is located'in the plurality of separated passages or pockets ex: space 2% in a wedged position so as to be in con tended longitudinally of the walls I0 and I2. tacting engagement with the sides of the grooves The air within the space I6 is thus incapable of 30 22 and 23. During the assembly of the wall the being circulated by convection since it is con ?ned in pockets formed by the tubes. tube I8 is initially positioned in the upper grooves 22 of lower blocks 2i and mortar I5 placed on The Walls In and I2, therefore, are thermally insulated from each other to in turn provide for a wall such lower blocks adjacent the tube I8. A next adjacent upper row of blocks 21 is then placed construction having e?icient thermal insulat~ 35 on the lower blocks with their bottom grooves 23 ing properties. opposite the upper grooves 2| of the lower row As illustrated in Figs. 1 and 2 two adjacent rows of bricks I 4 provide a vertical height of the outer wall I2 which is the equivalent of a single row of blocks I I in the inner wall ID. The 40 size of each tube I8 is such that when it is in serted in a wedged position within the space I6, its vertical height is substantially equal to the vertical height of a row of bricks I4, with the ?attened tube portions I9, resulting from the . - tube being wedged within the space I 6, extending substantially to the top of a row of bricks I4. As is clearly illustrated in Fig. 1 this construction and arrangement of the tubes I8 provides for alternate tubesin the space I6 having their ?attened portions I 9 extended substantially to the top of a row of blocks II. Thus when mortar is placed on the top of a row of bricls I4 or blocks II the mortar is prevented from entering the space It by the tubes I8 so that no mortar overruns the walls III and I2‘ into the space I6. Since the'mortar which ?ows or overruns into the space I6 performs no useful function in of blocks. The tube i8 thus prevents any mortar I5 from passing into the space 213 and provides a gap between the portions of mortar I5 to each side of the space 24 so as to prevent any ?ow of moisture through the mortar I5 from one side of the wall to the other. ‘ Although the invention has beendescribed with respect to several preferred embodiments there of it is not to be so limited since changes therein can be made which are within the full intended scope of this invention as de?ned by the appended claims.
