FORM TIE AND SPACER CONSTRUCTION.

Application led November 6, 1923. Serial No. 673,060.

To all whom t'may concern.'

Be it known that I, HARRY A. ORLoPP, a citizen of the United States, residing at Venice, in the county of Los Angeles and State of California, have invented new and useful Improvements in Form Tie and Spacer Construction (#3), of which the following is a detailed specification.

This invention has to dol with ties and spacers for concrete forms orthe like; having to do with a tie and spacer device somewhat similar to those set out in issued Patent #1,468,790, dated September 25th, 1923,

and in co-pending application Serial No. 651,813, filed July 16th, 1923, by the undersigned together with David Baker Smith. The devices which form the subject matter of this present application however, are

somewhat different inl structure from those shown in said patent and said prior application, in that in the prior structures the form board receiving notches are made, specifically, in V-shaped ridges,.wliile in the present form the board receiving notches are made iii iianges that extend up and down from the central flat plate. The speciiic formation of preferred forms embodying the present invention will be best understood from the followingdetailed description. The

- general object of the present invention is to provide a tie and spacer for concrete or like forms that will give strong and rigid support to the form boards or plates and at the same time is simple and inexpensive in its structure. It will be understood that where I refer to form boards I mean to include here form boards or plates or the like that are or may be used as the confining elements of a concrete or like form. It will likewiseA be understood that although I will describe my device as preferably being made of sheet metal, it is obviously not necessarily so made. These and other modifications and changes will be apparent to those skilled in the art from a consideration of the followingdetailed description of preferred and specific 4forms illustrative ofthe invention,

which forms are shown inthe accompanying drawings in which Fig. l is a perspective lof one form of my device;

Fig. 2 is an end view showing a modified formation of the form shown in Fig. 1;

Fig. 6 is a perspective illustrating another I form that my device may take;

Fig. 7 is a cross-section illustrating another method of forming the device of Fig. 6;

Fig. 8 is a fragmentary perspective showing a modification of the form of-Fig. 6; Fig. 9 is a perspective showing another modified form of the device;

Fig. 10. is a perspective showing another modified form of the device, and

Fig. 11 is an end view of the form of Fig. 10.

Referring first to Fig. 1 I show there a device that includes a central flat pla-te 10 with wide flanges 11 at each of its longitudinal edges. These anges project equally above and below plate 10 and have form board receiving notches 12 formed in them above and below plate 10. Likewise, these flanges 11 may have reinforcing rod receiving notches 13 formed at their edges to take horizontal reinforcing rods; and plate 10 appear in the drawings; it will beV understood that the devices may be put in various positions. In Fig. 1 for instance, the device is shown in a position to act as a tie and spacer between opposite form boards of aform for a vertical wall, and in which the.

section of Fig. 5. However, it will be readily seen that the device will act just as well to lforni boards are laid edge t o edge on top each other, as is illustrated in the vertical tie and space between boards that are placed with vertical edges in abutment. Fig. 5 might as well be a horizontal section as a vertical section. p-

In using the device of Fig. 1 the lower notches 12 are placed over the upper edges of opposite form boards A and then the next course of form boards B is placed at the upper notches 12 the plate 10 thus lying between the adjacent and substantially abut- -ting edges of boards A and B. I have found boards where plates are placed, though this may be done if desired.

The flanges 11 not only provide members in which the notches 12 and 13 are out but they 'also provide strengthening flanges for plate 10,l strengthening it both as regards longitudinal tension and longitudinal compression. I l

In the form shown in Fig. 1, plate 10 may y 4be secured to flanges 11 in any suitable manner, either mechanically, orby brazing or welding. In Fig. 2 I show how the whole device may be made up of -a single sheet of metal. Here the metal inthe fianges is doubled at-one side of plate 10, as is illustrated at 11a. This not only provides an easy mode of manufacture but also further .strengthens the device.

In F1g.,3 I show what amounts to two channels secured together at their webs 101. These webs, forming the central. plate, may

' be secured by riveting or by brazing or welding. And in Fig. 4 I show how, in such a form as illustrated in Fig. 3, the ends of the fianges may be' stifened.` and reinforced Aagainst outward thrust, this being done by* forming .the 'metal diagonally as 'illustrated at 14. `This formation of the metal at 14 materially strengthens the outer and end parts l1b of the flanges against bending or i crumpling under the outward strains imposed upon-those parts of the flanges by the interior concrete pressure.

In Fig. 6 I show a structure similar to that shown in Fig. 1, excepting that, at oneA side of plate 10 there is only a single flange 11. This flange 11c has the board receiving notches 12c and reinforcing rod 'receiving notches 130; while the two flanges 11 at the opposite side of plate 10 are formed as in Fig.' 1. In Fig. 7 I vshow a method of formation of the form shown in Fig. 6.

vI-Iere] the lower flange 11 is formed by bending the single sheet of vmetal back upon kitself to make the lower ange double; and the two thicknesses of metal may be left unconnected, except atv their lower edge or may `be riveted or brazed or welded together.

In Fig. 8 I show the diagonal formation 14 of parts of the metal adjacent the end portions 11b of the flanges 11. This method of formation may be applied where the form' is specifically that shown in Fig. 6 or is specifically that shown in Fig. 7 with the result in either case of strengthening the.

outer end portions of the flanges 11.

In Fig; 9 I show a metal plate l()d with a single flange 11d in the center of each side.

`notches hereinbefore described, I

notches.

Here the board receiving notches 12d'are cut downto the surfaces of plate 10. As a variation of the reinforcing rod receiving show not-ches 131 in bayonet slot form,v for the purpose of more securely holding then reinforcing rods without the necessity of tying the rods into place. Such form of notches may be utilized in any of the forms of device herein described.

In Fig. 10 two oppositely extending4 flanges l1e are shown at opposite edges of plate 10", the flanges .having the board receiving notches 12e and rod receiving notches 13e. And I also show the metal formed diagonally at 14 to support the end portions of flanges 11e as hereinbefore described.

Having described a preferred form of my invention, I claim:

1. A concrete tie and spacer embodying a .fiat metal plate adapted to lie between abut-ting edges of form boards or the like and extending between opposite boards of the'form, and flanges extending on opposite sides of the plate and at right angles thereto,.said fianges having form board receiving notches.
