Application December 23, 1939, Serial No. 310,666

(Cl. Y2- 103) 1 Claim.

This invention relates to wall constructions and particularly to improved means for bonding or tieing adjacent bricks in brickwork or the like.

It has heretofore been proposed, especially in brick construction of the type wherein the bricks extend in the main longitudinally with respect to the wall and where several thicknesses of brick are provided, to provide extraneous means for bonding or tieing the Ainner and outer rows of brick against relative displacement. According to the teaching of the present invention a tie or bonding means is provided which possesses numerous advantages as compared with devices of this nature heretofore proposed.

Some of the factors which are important in the production of a satisfactory wall tie for use in a construction of the nature set forth herein are ease and economy of manufacture, facility of placement, the ability to see the bond. or tie after erection of a wall for the purpose ci inspecting as to the number and proper placement of wall ties, and the elimination of possible injury to plasterers or other Workmen who may come in contact with the projecting portions of wall ties after their assembly in a wall. From all of these standpoints the construction proposed in my present invention marks a decided improvement over practices and constructions heretofore used and contemplated,

In the drawing:

Fig. l is an elevational View of a brick wall constructed in accordance with the teaching of my invention;

Fig. 2 is a vertical transverse cross sectional View of the wall of Fig. 1; and

Fig. 3 is a detail perspective view of a single wall tie.

In the drawing like characters of reference denote like parts throughout the several figures and the numeral IIJ designates individual building elements which may be in the form of ordinary bricks. In the illustrated instance the bricks are shown as laid in a very common arrangement which is usually referred to as stretcher bond. As will be seen from Fig. 2, the brick wall, which is shown as an example, comprises inner and outer adjacent tiers of bricks. It will be clear that the principles of the present invention may be applied to walls comprising more than two thicknesses of brick.

In constructing walls of the kind illustrated and in applying the teaching of the present invention thereto the surface of the wall appearing in Fig. l will be the interior surface.

Likewise in Fig. 2 the numeral II at the left designates the wall which will normally be presented to the interior of the building, while the numeral I2 at the right of the figure indicates the exterior of the wall. 'I'he several bricks comprising the wall are laid in general in the usual manner with the interposition of mortar for their securement as at I3.

To insure against relative displacement of the inner and outer tiers of brick, wall ties of novel form are provided. Such a tie is illustrated in perspective in Fig. 3 and comprises a flat expanse I4 of expanded metal and such expanded metal may be of the general type conventionally employed in the formation of metal lath. Adjacent one edge the at expanse I 4 has a return bent portion l5 which shows best in Fig. 2.

The return bent portion I5 terminates in an edge I6 which is spaced from the plane of the flat portion I4 a sufficient distance to insure its abutment with the exposed vertical surface of a brick or bricks lying below the wall tie proper when such tie is assembled in the mortar I3 and between vertically adjacent courses of brick. It will be apparent that the wall ties I4, I5 are assembled by placement in the mortar after such mortar has been spread on top of a course of brick and before the next higher course of brick is placed in position.

The abutment of the edge I6 with the faces of the course of brick immediately below the wall tie insures accurate transverse alignment of the wall tie and assists t0 retain such wall tie in properly placed position during the process of assembling the next succeeding course of brick. The formation of the return bent portion I5 provides convenient handling means for the wall tie and serves the further very useful purpose of eliminating the raw, jagged edge of expanded metal which would otherwise be presented.

As will be seen from a consideration of Fig. 1, the wall ties need only be employed between bricks at an interval of several vertical courses and at the present instance the ties are shown as occurring between every ve courses of brick. Considered horizontally, the wall ties occur, in the present example, in connection with every other brick in a horizontal course.

A single specific embodiment of the principles of my invention is set forth herein by way of example. It is obvious that certain modifications may be made without departing from the spirit of the invention which is not to be considered limited otherwise than as defined in the appended claim.

tending inwardly past the inner row and terminating inwardly in a marginal portion bent downwardly and then horizontally toward said wall to abut the inner brick surface of the wall, said marginal portion forming a return bent ange extending parallel to the Wall and serving as a handling portion and a locating means.

LEONARD E. BALDWIN.
