WALER BRACKET Filed Dec. 3, 1941 INVENTOR v/AMES C. MOSHE? ATTORN 5 Patented Sept. 15, M3342 WALER. BRACKET James C. Mushet, Roselle Park, N. J assignor, by mesne assignments, to Ralph E. Ogden, New

Application December 3, 1941, Serial No. 421,419

4 Claims.

This invention relates to improvements in waler brackets, and its object is to provide a simple device for facilitating the erection of forms for receiving poured concrete. More specifically, its object is to provide brackets which may be applied readily to the vertical stringers of concrete forms of standard construction for supporting walers thereon.

In the following specification I will describe a bracket which embodies this invention, show how it is used and point out its novel features in appended claims.

Referring to the drawing,

Fig. 1 is a transverse elevation partly in section of a standard form for receiving concrete, showing waler brackets applied thereto;

Fig. 2 is a bottom plan sectional View of some of the parts shown in Fig. 1, the section being taken on the line 22 of the latter figure;

Fig. 3 is a perspective view of a waler bracket which is made according to and embodies the present invention;

Fig. 4 is an end View of the bracket shown in Fig. 3; and

Fig. 5 is a view similar to Fig. 4 showing a modified construction.

Forms for receiving poured concrete are commonly built up as shown in Fig. 1 with spaced side walls iii, ll, spaced vertical stringers I 2, I 3 and spaced longitudinal walers I 4, I5 and l6, H. The parts Ill, l2, l4 and [5 are fastened together and so are the parts ll, l3, l6 and I1. These groups of parts are held together in spaced relation by tie rods, such as that shown at 2|], and by wedges 2|. This is more fully described in my copending application for patent Serial N 0. 419,859, filed N ovember 21, 1941.

The walers are usually provided in pairs and in setting up such a form it has been necessary heretofore to provide some makeshift arrangement for holding the lower waler of each pair in desired position until it is fastened to the vertical stringers. Such arrangements entailed the expenditure of time and the use of material which usually was thrown away after it had performed its temporary function.

The time required for setting up such forms is lessened materially by the use of the brackets which I have invented. A preferred form of such a bracket is shown in Figs. 3 and 4. It comprises a, fiat face portion 30 adapted to abut the outer surface of a vertical stringer. From one end of this face portion 30 extends at right angles thereto an arm 3|. From the other end of the face portion 30 a side portion 32 extends at right angles in the opposite direction. 33 is a prong which projects from the other end of the side portion in a direction substantially parallel to the face portion 30. The base of the prong is preferably narrower than the other parts of the bracket. 34 is a hole in the side portion 32 intermediate the face portion 30 and the prong 33.

When the concrete form is being set up and the vertical stringers are in place, two or more of these brackets are applied to spaced vertical stringers in horizontal or other desired alinement. With the face portion 30 resting upon the outer surface of a stringer and the arm 3| held in a horizontal position, the prong 33 is driven into the stringer by hammer blows until the side portion 32 abuts the side of the stringer. The bracket is then ready for use, but greater rigidity may be secured by driving a nail 35 through the hole 34 into the stringer. The lower walers l5 and ll of each pair may be then placed on the arms SI of the brackets and toe-nailed to the vertical stringers. The upper waler of each pair may be supported upon the lower waler by interposing suitable spacers. Ihese brackets are easily applied and may be removed for reuse.

In Fig. 5 the base of the prong 33A is as wide as the other parts of the bracket and its edges are sharpened as at 36.

It is possible to make these brackets of other forms than those shown and described for illustrative purposes without departing from the spirit and scope of this invention and I intend no limitations other than those imposed by the appended claims.

What I claim is:

1. A waler bracket comprising a strap bent to form two portions at right angles to each other, adapted to abut a side and the outer surface of a vertical stringer of a concrete form, means for securing the portion of the strap which abuts the side of the stringer to the stringer and an arm projecting outwardly from the portion of the strap which abuts the outer surface of the stringer.

2. A waler bracket comprising a strap bent to form a face portion adapted to abut the outer surface of a vertical stringer of a concrete form, an arm projecting laterally from one end of said face portion, a side portion extending at right angles in the opposite direction from the other end of the face portion, and means securing said side portion to the stringer, said means being arranged to hold the face portion of the bracket against the outer surface of the stringer.

3. A waler bracket comprising a strap bent to form a face portion adapted to abut the: outer surface of a vertical stringer of a concrete form, an arm projecting laterally from one end of said face portion, a side portion extending at right angles in the opposite directon from the other end of the face portion, and a prong projecting from the outer end of the side portion in substantial parallelism with the face portion, said prong being arranged to be driven into the side of the stringer to hold the face portion against the outer surface of the stringer.

4. A waler bracket comprising a strap bent to form a face portion adapted to abut the outer surface of a vertical stringer of a concrete form, an arm projecting laterally from one end of said face portion, a side portion extending at right angles in the opposite direction from the other end of the face portion, and 2, prong projecting from the outer end of the side portion in substantial parallelism with the face portion, said prong being arranged to be driven into the side of the stringer, said side portion having a nail hole therein intermediate the arm and the prong.
