Specification of Letters Patent.

Application fiel d March 12,1917. Serial No.154,105.
To all whom it may concern:
Be it known that I, AVILA O. THOMAS, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Wall-Bond, of which the following is a specification.
This invention relates to tie members for building blocks and its object is to provide a tie member particularly adapted to establish and maintain the proper degree of rigidity in a wall comprised of two-part blocks such as is disclosed in my co-pending application, Serial Number 154106.
More specifically related, it is the object of the invention to provide a tie member, comprised of two relatively adjustable members, which, after being engaged with two blocks or tiles, may be adjusted to and locked in an angular relation so as to create a sufficient tensile stress in the tie member to hold the blocks firmly .in a desired relation.
An exemplificaton of the novel means provided for accomplishing the aforesaid object is illustrated in the accompanying drawings, wherein,
F igurel is a perspective view of the tie member, showing the parts thereof adjusted in their tension-producing position and showing also the fasteners with which the extremities of the tie member are engageable.
Fig. 2 is a top view of the tie member, showing the relative position of the parts thereof when first extended between two tiles. 1 V
F ig.3 is an elevation view of the same, the tension-producingposition of the parts being shown in dashed lines. l
Fig. & is a horizontal sectlonal view showing a tile wall construction wherein the herein-described invention is employed.
Referring now more particularly to the drawings, wherein like reference characters designate similar parts in all the views, 1 denotes two duplicate metal bars having overlapping end portions through which there is centrally passed a loose rivet 2, or equivalent pivotal connection. This connection not only allows a relative angular motion of the bars 1, but also permits the overlapping portions to assume a slightly spaced relation, as may be clearly seen m Fig. 2. Between its pivotal p'omt and its adjacent extremity, each bar 1 is formed with a flange 3 extending at an acute angle to the longitudinal edges. When the two bars, are in alinement, -or nearly so, the flanges 3 bear respectively upon the opposed over-lapping portions and maintain between sald portions an interval of space somewhat greater than the connection2 readily permrts. Consequently when the bars 1 are shifted to permit the flanges 3 to clear the side faces of the bars said flanges will each snap into engagement with an edge face of the opposing bar, thus forming an interlock prohibiting return of the two bars to an; alined relation. If, therefore, the tie member has its parts substantially in alinement when their outer ends are engaged with two bodies or structures to be connected bysaid member, and subsequently the bars 1 are adjusted to their relative positions disclosed in Fig. 1, it is evident that the distance between the tie extremities will be decreased,
and there will result a tensional stress in j the tie member that will give rigidity to the connection.
, While a tie member such as has been described has numerous applications, it is intended primarily to be employed in a wall construction, and more especially in a wall constructed of two part tiles which is the subject matter of my copending application, Serial Number 154,106.
Referring now to Fig. 4, illustrating this application of my invention, 4 is a tile formed of any suitable cementitious ma terial and 5 are ribs extending parallel to the endsof the tile and set back respectively therefrom. One or more ribs 6 extend longitudinally of the tile, the height thereof being I uniformly increased from the ribs 5 to an intermediate point 6' whereat the height of of said tiles in juxtaposition with the ribs 5 and 6 abutting, a composite hollow block is formed, and when a number of said blocks are arranged in a row, the ribs 5 adjacent each transverse point together with the abutting end portions of the tiles form a rectangular opening 7. At the corners of this opening there are partially embedded in the respective tiles U-shaped brackets 8, the loops thereof projecting and the legs having bent ends 8 to increase the anchorage. These brackets form diagonally opposed pairs, each of which pairs is engaged with hooks 9 formed upon the extremities of one of the previously described tie members. The length of the tie members is so propor tioned with respect to the distance between the brackets to be engaged thereby that the tie members may be readily engaged with said brackets while the bars 1 are in alinement, but subsequent to adjustment of said bars to their angular interlocking relationa considerable tensile stress will be created that will hold the four tiles meeting at the joint infirm abutment, V
The openings 7 may be filled with concrete as indicated at 10 in Fig. 4. Vertically extending reinforcing rods 11 are also shown embedded in the concrete 10, and engaged with tongues 12, respectively struck but from the outer end portions of the bars 1. By this arrangement said bars are held in their proper positions while'the concrete is being poured, and a bond is established between the rods 11 and tie members so that stresses may be transmitted from one to the other.
The adjustment of the tie members may be readily effected by exerting upward pressure upon said members below the pivotal point thereof, ahooked implement (not shown) being well adapted for applying such pressure. It will of course be understood that the concrete filling will not be introduced into the openings 7 until all of the tie members have been adjusted to tensilely stress thesame.
The invention is presented as including all such changes and modifications as properly come within the scope of the following claims.
What I claim is:
1. A tie member comprising two bars and a pivot member connecting end portions of said bars, said pivot member being axially dimensioned topermit the bars to assume a spaced relation and projections from the IQSPQCtlV-B-COIIHGCtGd611d portions of the bars engageable between said portions when the bars are in substantial alinement and coac'ting' to maintain amaximum space intervalibetween the bars, each of said bars having an edge engageable by the projection from the other bar upon establishment of an angular relation between the bars such as to shift said projections from between the same, and thereby permit a decrease of the intervening space interval.
2. A tie member comprising two bars and a pivot member connecting end portions of said bars, said pivot member being axially dimensioned to permit the bars to assume a spaced relation, and flanges formed integral with the respective connected end portions of the bars, engageable between said portions when the bars are in substantial alinement and co-actingto maintain a maximum space interval between the bars, each of said bars having an edge engageable by the flange from the other bar upon establishment of an angular relation between the bars such as to shift said projections from between the same, and thereby permit a decrease of the intervening space interval.
3. A tie member comprising two bars and a pivot member connecting end )ortions of said bars, said pivot member being axially dimensioned to permit the bars to assume a spaced relation, and flanges formed integral with the respective connected end portions of the bars, extending symmetrically to the pivot member and at an acute angle to the longitudinal edges of the bars, said flanges being engageablebetween the connected end portions when the bars are in substantial alinement and co acting under such conditions to maintain a maximum space interval between the bars, each of said bars having an edge eng'ageable. the flange of the other bar upon establishment of an angular relation between the bars such as to shift said projections from between the same, and thereby permit a decrease of the intervening space interval.
In testimony whereof I sign this specification.
