To all whom it may concern:

- Be it known that l, Gannon WASHINGTON LEnKnnn, a citizen of the United States, and a resident of Indiana, in the county of lindiana and State of Pennsylvania, have invented a new and Improved Wall Construction, of which the following is a. full, clear, and exact description.

This invention relates to building construction and has particular reference to the formation of walls out of precast or otherwise formed building units.

Among the objects of the invention is to provide a means or method for building a wall, using for such purpose mainly hollow bricks of a uniform standard type or form having straight parallel walls and with one v or more openings entirely through the cen ter from end to end, and at the same time provide a means for forming the corners, trimmings, arches or the like, of solid bricks of a composition and size corresponding to the outside appearance of the hollow bricks.

Without limiting the scope of this patent unnecessarily as to the particular type or design of hollow bricks to be used, I may state, for an illustration of a suitable hollow brick, that the one which I have used extensively in the practice of this invention is the one described and claimed in mycopending application filed August 21, 1915, Serial No. 46,744. The essential characteristic, however, of the hollow brick is that it shall present or have an outside appearance as to composition, color, or lines of pointing, to correspond with standard sizes or compositions of common solid bricks.

With the foregoing and other objects in View, the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed herein, still for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings, inwhich like reference characters designate the same parts in the several views, and in which-- Figure 1 is a perspective view of a fragment of a wall made in accordance with this invention, the main portion of the wall being composed of hollow bricks, while the corners and trimmings are of solid bricks, both types of bricks having the some designat the surface; and. Fig. 2 is a vertical sec-' Specification of Letters Patent.

tional View of a portion of the same wall on a plane parallel to the front'surface thereof.

Referring now more particularly to the of a length corresponding to that of one of the solid bricks 11 and of a height corre; sponding to that of two solid bricks with an intermediate layer of mortar 12. Also the hollow'bricks are grooved or scored longitudinally along their sides midway of their height, as indicated at 13, to receive a line or pointing of mortar resembling the mortar 12 in outside appearance.

In the rapid and economical construction of a building wall, it is essential that the hollow bricks shall all be of the same type, and for the formationpof a hollow wall it is also essential that the hollow spaces in the hollow bricks must extend fully from one end to the other, whereby the air passages are continuous throughout? series of all of the hollow bricks arraTnged end to end. It will be appreciated, therefore, that with the foregoing conditions it is impossible to form a corner of the wall or any other irregularity in the wall with any of the ends of the hollow bricks exposed.

By reference now more particularly to Fig. 2 it will be appreciated that there is a decided advantage in the method of wall construction that I employ and describe herein, the same involving the use of solid bricks 11, of the same standard dimensions as represented by the grooving or scoring on the sides of the hollow bricks, for the for1nation of the corners 14 bounding the ends of the wall or the side edges of a niche. The arch 15 also is preferably built of solid bricks 11'.

A wall built in accordance with this method has all the advantages of ordinary hollow walls, practically the full strength of walls built of solid bricks, since the corners or other exposed parts that are most susceptible of damage or crushing are of solid bricks, and may be built at a much lower cost than other walls because of the uniformity of the material and the rapidity with which the building elements may be laid. The mason or bricklayer can lay a wall of this character more expeditiously than of solid bricks for the reason that the principal elements of the wall being hollow and of a larger volume than the individual solid bricks, he, in handling one of the hollow bricks exerts practically no more eflort or time than in the laying of a single solid brick, and obviously accomplishes a larger result. Furthermore, in the formation of a wall in which only hollow bricks are used, special forms must be relied upon for the irregularities or corners of the wall. Special hollow bricks are always vastly more expensive than standard hollow bricks having straight passageways from end to end, not only because of the increased difiiculty in the formation of each of such special forms, but more so because of the fact 7 that so many different special forms are required, whereas, where the solid bricks may be relied upon for the formation of the cor: ners and other irregularities, there is practically no Waste of time and the operation is Copies of this patent may be obtained for five cents each, by addressing the carried out at a minimum expense for material and labor.

In a composite building wall, the co1nbiv nation of a plurality of hollow bricks for the main portion of the wall, a plurality of solid bricks for the vertical edges ofthe Wall, and courses of mortar of uniform' thickness arranged between adjacent bricks of both species, the hollow bricks being of a height exactly equal to a plurality of solid GEORGE WASHINGTON Witnesses: v
