TIE FOR REENFORCED CONCRETE CONSTRUCTION.

Application filed April 12, 1921. Serial N0.460,687.

To all whom it may concern:

Be it known that we, HARRY E. CLOUSER and EDGAR R. THORNTON, citizens of the United States, residing at Stockton and Los a Angeles, respectively, counties of San Joaquin and Los Angeles, respectively, State of California, have invented certain new and useful Improvements in Ties for Beenforced Concrete Construction; and we do I declare the following to be a full, clear, and

exact description of the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in building construction, and especially with regard to the use of interlocking concrete block built up to form a doublewall.

The present invention is particularly intended to show certain features of improvement over what is shown in our co-pending application for patent filed February 9th, 1920, Serial No. 357,458, and allowed September th, 1920, and especially as to the form of tie employed, the principal object of this invention being to provide a tie which will not only firmly hold the two thicknesses of the wall in place, but interlocks with the individual blocks as well.

Our improved ties also permit greater ease in laying up the blocks, since they aid in getting true alinement of the block with out any great attention being necessary on the part of the mason.

Another object is to provide a tie, intended to be used with our particular design of block, which can be quickly and easily applied to the blocks, and which, when once so applied, cannot easily be disturbed in such a manner a to make them fall out when other blocks are being superimposed on the row below.

We have also improved the block itself, so that without destroying the interlocking features thereof, more space is left for the necessary binding mortar or thin grout preferably used, so that a very firm bond may be had.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purposes which it is designed.

These objects we accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views.

Fig. l is a fragmentary perspective view of a double wall, showing our improved blorlxlks and the ties used in connection therewit Fig. 2 is a detached view of a block.

Fig. 3 is a detached view of a tie.

Fig. 4 is a fragmentary cross section through a pair of adjacent blocks, showing the tie positioned therebetween.

Referring now more particularly to the characters of reference on the drawings, the numeral 1 represents in eneral the blocks employed, these being preferably of the type shown in our co-pending application for design patent filed August 16th, 1920, Serial No. 403,953, the outstanding feature of these blocks, making them interlocking, being longitudinal grooves 2 on their upper surfaces, and corresponding ridges 3 on the under surfaces, the ridges being about the same width as the grooves, but the latter being considerably deeper, as shown in F igj 4, both ridges and groove being preferably of curved outline.

The blocks are laid in horizontally spaced rows, so as to form a double wall, having an air chamber or space therebetween, the advantages of which construction, especially with the use of concrete as the building ma terial, are well known.

To connect and bind the two thicknesses of the double Wall together, we provide metal tie members 1, which are preferably made of thin sheet metal strips of suitable width.

These ties are intended to extend from the outer edge of the outer wall to the inner edge of the inner wall, and are provided with depressions 5 conforming in shape to and adapted to snugly seat in the grooves 2 of both horizontally disposed blocks.

It will therefore be seen that by the use of these ties, not only are the two thicknesses held together against movement to or away from each other, but in laying or building up the walls. they regulate and determine the distance therebetween, so that provided one wall is laid true, the other wall must of necessity be exactly parallel thereto throughout its extent.

Further, the ties, which of course are laid across the blocks before others are superimposed thereon, aid in insuring of a true alinement and seating of the latter blocks, since while these ties may readily be stamped so that all are perfect duplicates of each other, the concrete blocks, when made in the ordinary commercial manner, are of necessity somewhat rough, and cannot be absolutely depended on for exact uniformity, and besides, as previously stated, the grooves and ridges are not the same size, which leaves room for deviation from true alinement with adjacent blocks. The ridges and grooves however are purposely proportioned as shown, since we do not depend on these members for true alinement of the blocks, and valuable space is thus had which is just sufficient to receive the thin grout or cement used to bind the blocks and which of course is essential.

At the same time, the seat of the ridges in the grooves is not destroyed, since the blocks are not raised or separated from each other to any extent as would be the case when the cement-was poured if said ridges and grooves exactly coincided.

For ordinary walls, "cry thin ties may be used, so that they may merely be laid across the blocks at intervals to suit, since their thickness is a negligible quantity.

In the case of a heavy structure or one to be subjected to severe strains and shocks,

thicker ties must be used. which would separate the blocks to an undesirable extent.

The upper surface of each block (which is that surface having the ridges 52 therein) is recessed at suitable intervals as shown at 6, to a width and depth equal to the thickness of the ties to be used.

These recesses must of course be positioned so that the blocks may be interchanged and without interfering with any transverse interlocking features of the blocks themselves (such as the lugs 7 shown in Figs. 1 and 2).

The blocks in the two rows are also preferably laid so that the abutting ends of the blocks in one row are half way between those of the other row.

We have therefore provided a full width tie recess centrally of each block, and a halfwidth recess at each end, which latter of course combines with the similar recess on the adjacent block to give the necessary width, as shown in Fig. 1.

Each block thus gets the benefit of three ties, or as many more as can be arranged intermediate the ends, while still allowing the blocks to be interchanged.

From the foregoing description it will readily seen that we have produced such a device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to and do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described our invention what we claim as new and useful and desire to secure by Letters Patent is:

1. In building construction, building blocks therefor, a ridge along one edge of each block, and a groove to 'co-operate with said ridge along the abutting edge of an adjacent block, said ridge being shallower than the groove whereby when the blocks are placed one on the other a tie may be seated between said ridge and groove without causing the blocks to separate, and space is bad for a binding material, the edges of the blocks on each side of the grooves being recessed at intervals to receive the ties and allow the same to lie flush with said edge.

2. In building construction, the combination with building blocks laid in horizontally spaced rows, the edge-faces of adjacent blocks being provided with cooperating ridges and grooves, of tie strips arranged to be positioned and extend between the blocks of each row, said ties comprising fiat portions and intermediate bent portions shaped to lie in the bottom of the grooves, the edge surfaces of the blocks on each side of the blocks being recessed to receive the flat portion of the tie therein, the blockridges being shallower than the grooves whereby when the blocks are in position space between the ridges and grooves remains for the bent portion of the ties without recessing the ridges or grooves to accommodate the same.

In testimony whereof we aflix our signatures.

HARRY E. CLOUSER. EDGAR R. THORNTON.
