FORM non coNcaErE srauo'ruans.

Application filed October 4, 1923. Serial No. 666,597.

This invention relates to forms for contional metallic form consisting of a suitable number of sections or units of a variety of forms, all of which may be inexpensively produced from plates and standard struc tural shapes, which sections easily and quickly assembled to constitute a form fora wall in accordance with substantially any plan, which form, when set up, is securely supported and braced and is other wise of suificient strength to perform its intended function, and which can be as readily disassembled after the wall has set, the sections being capable of repeated use in different assembled relationships for an indefinite period, and being practically indestructible.

The foregoing and other objects of the invention, together with means whereby the same may be carried intoefi'ect, willbest be understood from the-following description of one embodiment thereof illustrated in the accompanying drawings. It will be understood however that the particular construction andarrangements described and shown have been chosen for -illustratlve purposes merely, and that the invention, as defined by the clai-rns hereunto appended, may be other- -wise practised without departure from the spirit and scope thereof.

Fig. 14 is a perspective iew of an assembly of the units shown inthe preceding figures to constitute a form for a short angular,

Fig. 15 is a detail horizontal sectional view site sides of the form.

The form herein shown comprises a suitablenumber of sections of different shapes which may be assembled to build up a form of any desired size and configuration, v together with keys for connecting the assemw bled sections, and members for 'alining the sections and supporting and bracing the form as a whole.

As herein shown, the sections comprise flat, side and end panels which 'form the straight sides and ends of the wall, outside corner members for connecting the panels at the exterior corners'or angles ofi'the wall, and inside corner un ts for forming "the interior angles.

In Figs. 1 to 5is illustrated a flat panel section indicated as a whole by the numeral QO -Said panel comprises a {rectangular metal plate 21 of a length corresponding to the desired height of the form and whose 7 width may, as hereinafter explained, vary in accordance with the desired width of the panel of which it forms apart. Secured, as.

by spot-welding, to the upperand' lower edges of the plate'21, are channel bars '22,

while similarly secured to the lateral or ver- I tical edges of said plate are angle ba'rs23,

said channel and angle bars constituting a strengthening or stiii'ening frame for the 7 panel. The angle bars 23 are disposed with their flanges which are secured to theplate 21 turned inwardly or toward one another,

while the other flanges are turned outwardly parallel to one another and constitute outwardly projecting flanges at the extreme edges of the panel. Said outwardly pro'jectv 1 Clesections can be made, all of such sections being of the same length or height 11'- respective of their width. Said panel sections are assembled to constitute straight portions of the form, the

panels

200, 201, etc. being side panels, andthe panels 20 constituting end panels and being also used as side panels where short lengths are rcqui-red, as shown, for example, in Fig. 10, where one panel 20 is assembled with two panels 200.

Cooperating with the panel sections. for

' the purpose of alining and bracing the same and to constitute a top and a base for the assembled form, are angle bars which are provided in a plurality of lengths, two being shown at 27 and 270 in Figs. 8 and 9, and others being shown at 271 and 272 in Fig. 14. When a plurality of

panels

20, 200, etc. have been assembled in alined relationship, as shownin Fig. 10, an

angle bar

27, 270, etc. is placed horizontally and longitudinally ofthe series at both the top and bottom thereof, one flange'of said bar being inserted in the. alined end slots 25 of the .abutted flanges 23 of the contiguous sections, the other flange of said angle bar overlying and engaging the ends of said flanges 23, as shown in Fig. 11. 1

The outside corner sections comprise angle bars 28 (Figs. 12 and 14) of a length corresponding to the height of the panel sections, the flanges of said angle bars being formed intermediate their ends with slots 240, corresponding in number and arrangement to the slots 24 in the flanges 23,- and in their ends with open slots 250 corresponding to the slots 25 of said flanges 23.

Each inside corner section,rdesignated as a whole in Figs. 13 and 14 by thenumeral 29, comprises a permanently assembled unit consisting of two plates 30 disposed at an angle to one another and the inner or proximate edges of which are secured toa vertical angle bar 31.

To the outer edges of said plates are secured, vertical angle bars 32 which are similar in form and arrangement to the angle bars 23 of the panel sections, said bars being formed intermediate their ends with slots 241 corresponding to the slots 24 and in their ends with open slots 251 corresponding to the slots 25. The

interior angle of the unit thus constructed 1s braced at the top and bottom of said unit by an angular channel bar 220, corresponding .to the channel bars 22 of the panels.

Theseveral sections above described are secured tog-ether in assembled relationship by bifurcated'gravity keys 35, whose form is most clearly shown in Fig. 10. Each of said keys comprises a flat metal stamping 0t U-shape including a head 350 having rounded corners and depending legs 351 the opposite inner edges 352 of which converge toward the head 350. lVhen the

contiguous flanges

23, 28, 32, etc, of adjoining sections are placed in abutted engagement, with the

slots

24, 240, 241, etc. in register with 7 one another the keys 35 are inserted laterally through the registering slots, as shown at the upper left-hand corner of Fig. 10, the rounded heads 350 facilitating such insertion, and the depending legs 351 caused to embrace the abuttingflai s. Thereupon said keydrops by gravity into a position wherein the converging edges 352 tend to wedge the flanges tightly together, and subsequent use of the structure tends to lock them more tightly. In Fig. 14 is shown an assembled form comprising six panel sections 200, constituting the side panels, two panel sections 20 constituting end panels, live outside corner sections 28, and one inside corner section 29, all secured together by keys 35, and a suitable number of top and bottom

horizontal angle bars

27, 270, 271, and 272. Said angle bars'arc engaged with the end slots of the vertical flanges of the several sections, the lower" angle bars constituting, a base for the form, and the upper angle bars constituting a reinforced top which may also serve as a support for another set of sections superimposed upon the/section shown. V

In Fig. 15 is illustrated means for tying together opposite side panels of the form in order to prevent spreading thereof when the wall is poured. As shown insaid figure,

the plates 21 are formed with oppositely dis posed openings 40 which receive looped portions 41 of a transversely extending wire 42. Into the loops 41 at the exterior of the plates 21 are inserted nails 43. After the wall is poured, the nails 43 are removed, the panels 21 withdrawn laterally, and the loops 41 cut off, leaving the body of the' wire 42 in the wall.
