STRUCTURAL BRICK.

Application filed. March 5, 1919. Serial No. 280,708.

T 0 all to 7mm itmay concern:

Be it known that I, Isaac V. Van Dozen, of Cazenovia, in the county of Madison in the State of New York, have invented new and useful Improvements in Structural Bricks, of which the following, takenin con nection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvements in structural bricks for walls and other uses to which the specific form of the brick may be applicable.

The main object is to render the work of brick-laying more expeditious, economical and efficient and at the same time to produce a lighter wall having greater strength and less moisture transmitting factors than has heretofore been practised.

In other words i have sought to produce what may be termed a one-piece double brick composed of two parts of substantially the same dimensions integrally united edge to edge but offset longitudinally a distance substantially equal to the width or half the length of either part so toafford a wide range of variation in the relative arrangement of the several units during progressive building, and thereby permit the formation of corners, window and door reveals, piers and other needful or ornamental configurations with a minimum breakage or reformation of the units.

One of the Specific objects is to channel the parts of the several units and to assemble said units in such manner as break the continuity of solidity through the completed wall at practically all points in its thickness and to thereby prevent the transmission of moisture therethrough.

Another specific object is to permit the construction of walls of diiferent thicknesses in multiples of the width of one of the parts of a unit, and at the same time to maintain a bond of maximum strength between the bricks of each course and also between the several courses.

Other objects and uses will be brought out in the following description.

In the drawings- Figures -1 2- and 3 are perspective views of my improved brick showing both parts channeled, one part channeled and the other part solid, and both parts solid respectively.

Figure -4- is a perspective view of a part of a wall built from the blocks shown in Figure -1--.

Figures 5- 6 7 and -8-- a re plans of walls showing different ways of assembling the bricks shown in Figures l with lengthwise channels '3 ektending from end to end thereof, and preferably rectangular in cross section, each channel being of greater width or depth than half the width or depth respectively of the part in which it is formed for the purpose of reducing the weight of the brick unit, and at the same time forming alr spacesto prevent transmission of moisture through the wall, the remaining faces of said unit being substantially fiat. I

In the structure shown in Figure 2 one of the halves or parts as 1 is channeled and the other half or part as -2-- is solid, while in Figure 3 both parts as -2- are solid. p

The structure in Figure -1 may be used in the construction of the main body of the wall, that shown in Figure 2, at one or more of the corners, window reveals, piers, or offsets in the walls, as shown in Figures 5 6 7-- and --8- respectively,

while that shown in Figure 3 may also I be used at one or more corners or window reveals, as shown in Figures -6- and -7.

It is sometimes necessary to use one half of one of the units for filling in certain places in the surface of the wall, as for example, two of the diagonally opposite corners of the structure shown in Figure 5--, and in order that the double brick may be more accurately broken along a medial line at the junction of one part with the other the opposite faces of said junction are pro vided with lengthwise scores or relatively shallow grooves -l along which the parts may be readily broken by a suitable tool usually provided for this purpose, the half brick being indicated at ---4:'-- Figures 5 and .--6-.

The double bricks or units are laid up with mortar at the joints except that the mortar is preferably omitted between the overlapping longitudinal edges to form air spaces 5, by which the transverse continuity of solidity of the wall is further broken to reduce the liability of transmission of moisture through the wall, as shown more clearly in Figure 4.

The brick units are laid course upon course in such manner that the channels of those in each course will register with those of the next adjacent course to form continuous air chambers throughout practically the en tire length. of the wall, as more clearly illustrated in Figure l, the chambers in adjoining parts of the assembled units be ing staggered vertically so that the chambers in the adjacent courses at one side eX tend vertically beyond the adjacent walls of the chambers of the same courses for the purpose of breaking the continuity of solidity transversely of the wall at all points, and thereby reducing the liability of transmission of moisture from the exterior through 'the wall.

What I claim is 1. A one piece double brick composed of similar rectangular parts of substantially equal width and surface area integrally united edge to edge in the same plane, each part being ofi'set longitudinally relatively to the other part a. distance substantially equal to its width.

2. A one-piece double brick composed of similar rectangular-parts of substantially equal width and surface area integrally united edge to edge in the same plane, each part beingoffset longitudinally relatively to the other part a distance substantially equal to its width and provided with a lengthwise channel extending from endto endthereof.

3. A one-piece double brick composed of similar rectangular parts of substantially equal width and surface area integrally united'edge to edge in the same plane each par-t being offset longitudinally relatively to the other part a distance substantially equal to its width and provided with a lengthwise channel extending from end to end thereof, one of said channelsbeing formed in one side and the other channel in the opposite side of their respective parts.

In witness whereof I have hereunto set my hand this th day of l ebruary, 1919.v
