BUILDING-BLQCK AND WALL CONSTRUCTED THEREUF.

Specification of Letters Patent.

Application filed April 27, 1906. Serial No. 813,912.

To all whom it may concern:

' Be it known that I, JULns REIL UT, a citi- Zen of the United States, residing at Dobbs Ferry, in the county of \Vestehester and State of New York, have invented certain new and usefulImprovements in Building- Blocks and Walls Constructed 'lhereof, of which the following is a specification.

This invention relates to new anrhuscful improvements in building blocks and walls constructed thereof and particularly contemplates a hollow block of novel'construction and possessing numerous advantages over the blocks ordinarily employed.

A primary object-of the present invention is to provide a block which in wall construction will not conduct cold or heat and which shall be free from dampness.

A further object is to provide a block which in assembled relation in wall construction shall present a plane finished surface practically unbroken, the adjacent edges of the blocks abutting one another in cmitziicting relation. 5

The detailed construction will appear in the course of the following description in which reference is had to the accompanying drawings forming a part of this specification, like numerals designating like parts throughout the severalwiews, wlicrein- Figure 1 is a perspective view of a block constructed in atcordance with the present invention, partly in section, Fig. 2 isan en'd elevation thereof, Fig. 3 is a transverse section thereof, Fig-J 1 is a fragmentary trans verse section showing the manner in which two adjacent blocks are joined, and Fig. 5 is a longitudinal section.

In the practical embodiment of my invention I employ a block 1 of substantially U- shape which is closed on three sides and formed with an opentop 2. The body'portion of said block is hollow and according to i the circumstances of its use, may be divided into a plurality of air chambers, a central partition 3 extending vertically fronr the ot- -tom t and dividing the block into air chambers 5, as shown in Fig. 5.

The side walls (5 are formed adjacent to the bottom 4 with depending flanges 7, coextensive with said side walls and formed with beveled inner surfaces 8. Said side walls are formed along their upper edges with similarly constructed flanges 9 adjacent to the inner surface of the block. The flanges 9 are )l(.)

vided with bevel d outer edges 10 extcm ing with flanges 12 similar in construction andarrangement to the flanges 7 and 9.

Upon reference to Fig. 4,'it Will be noted that in assembling the blocks to form a wall, the flange 9 and the shoulder 11 u on the one block are seated in interlocking re ation u on the flanges 7 of thelowermost blockf' t is to be noted that the flanges 7 are of greater depth than the flanges 9, so that a space 12 occurs between the wall 4 of the one block and the flange 9 of the adjacent overlying block. The shoulder 11 engages the upper edge of the flange 7 and the beveled edges 10 and S of said flangestl and 7 abut one another throughout their lineal extent. 111' a wall constructed of m wimproved block, the joints between the bloeks are on the inside. thereof, that is in the lower portion of the air chambers 5. As shown in Fig. 4' mortar 125 or any other suitable binding agent spread upon the surface of the wall t, .[ills the space 12 before. mentioned and ellccts a sealed in nor joint between the adjacent blocks.

\Vhcn the air chambers 5 are sealed, dead airspaccs are formed throughout the entire length of the wall. which are practically nonconductors of cold or heat and which .csisl the pom-.tration of moisture. Inasmuch as the joint between the blocks is on the inside thereof, the faces of thecxposcd walls may be highl linishcd in accordance with the methods practiced in the art to present an ornamental interior or exterior surface here it is desired to paper the wall, it is not necessary to employ a plastering or smoothing agcnt, as the paper may be placed directly upon the smooth and practically unbroken surfacc of the blocks in their assembled relation. The pressure of the air in the chambers 5 serves to prevent the mortar from rising in said chambers and to spread said mortar to till the interstices 12.

Having fully described my ii ivention, I

claim:

' 1.. In a building. block of the character dcscribcd, the combination of a hollow rectangular body portion of substantially U-shape in harms-section, and comprising horizontal portion and sides depending therefrom, and provided with upward extensions forming flanges cxtending longitudinallyaalong thfi.

the inner faces of said flanges being beveled and converging downwardly, the said sides having their lower edges formed with longitudinal shouldered flanges of less depththan the said first named flanges, the on ter surface of the said last named flanges being beveled and converging downwardly to conforinably engage the beveled surfaces of the said first named flanges of the adjacent block, the edges of the said shouldered flanges being thus spaced away from the surface of the horizontal portion of the adjacent block whereby a recessis formed for the reception of a bind- .agent,-substantially as described.

2. In a building block-of the character described, the combination of a hollow rectangular body portion-of substantially U-shape in cross-section and comprising a horizontal portion and sides depending therefrom having a central transverse partition bridging the same and forming sp'acedlopen chambers, and provided with upward extensions form- Y the flanges extending longitudinally along upper side edges of said'horizontal ortion the inner faces of said flanges being eving eled and converging dowiiwardly,' the said sides having their loweredges formed with longitudinal shouldered flanges of less depth. than the said first named flanges, the outer surface of said last named flanges being beveled and converging downwardly to conformably engage the beveled surfaces of the said first named flanges of the adj acent'block, the edges of the said shoulderedflanges being thus spaced away form the surface of the horizontal portion of the adjacent block whereby a recess is formed for the reception of a binding agent,

In testimony whereof I aflix my signature in presence of two witnesses.
