BUILDING FORM.

Application filed January 19, 1923. Serial No. 613,661.

To all whom it may concern:

Be it known that I, DANIEL B. DANIEL- soN, a citizen of the United States, and resident of lvlilwaulree, in the county of Milwauli-QG and State of lVisconsin, have invented new and usefulImprovements in Building Forms, of which the following IS a description, reference being had to the accompanying drawings, which are a part of this specily when considered in connection with the.

accompanying drawings, wherein:

Fig. 1 is a perspective view of the invention when used as a scaffold support.

Fig. 2 is a perspective View of the invention when used as a concrete form wall suport.

p Fig. 3 is a detailed perspective View of one of the supporting plates, and

Fig. 1 is a fragmentary elevation of the structure illustrated in Fig. 2.

Referring now more particularly to the drawings, wherein like reference characters indicate like parts, it will be noted that this improved construction consists of a plurality of uprights or supporting posts 10, which, obviously, may be of any desired length and to which there is secured a plu: rality of plate members 11, these members being secured to the uprights so as to project beyond one face thereof, these mem* bers being further arranged in spaced relation. Each plate member 11 is formed with a slot 12 for a purpose to be more fully hereinafter described.

Cooperating with the uprights 10 and the plate members 11 are angle bars 13 which are adapted to engage with one of their sides the slots 12 of the plate members 11.

In the manner of using the invention as illustrated in Fig. 1, a plurality of the posts or uprights 10 are preferably positioned and are braced by bracing members 14. The angle bars 18 are placed in position so as to provide horizontal supports for transverse timbers 15 which support the platform boards 16 forinlng a scaftold platform. In

this use of the invention the posts or uprights 10 are so disposed that the plate members 11 project inwardly or toward one another whereby the angle bars 13 provide the proper support for the cross timbers 15 of the scaffold platform. In this arrangement it should be noted that the angle bars 13 and plate members 11 cooperate to brace and strengthen the uprights and form together a rigid support.

Referring now more particularly to Fig.

2, it will be noted that the invention herein illustrated is provided with supporting means for concrete form walls 17 between which concrete is poured and permitted to harden. In this arrangement, the posts or uprights 10 are reversed so that the plate members 11 project in opposite direction and in this instance, a plurality of the angle bars 13 are preferablv employed. The con crete form walls 17 are further held in propor relation by means of wires 18 which extend therebetween and braces 19.

In practice, the uprights 10 are positioned upon a concrete block 20 which has previous ly been formed and the wall boards 17 are nailed thereon. The plate members 11 are positioned outwardly so that the angle bars 13 may be easily inserted in the slots 12, and the whole structure braced and strengthened.

As is usual in concrete construction work,

the form walls are disassembled after the concrete has hardened and this is facilitated by the arrangement herein described.

From the foregong, it will be immediately apparent that building forms constructed in accordance with this invention provide means for either supporting scaffold platforms or for supporting the concrete mold walls. When the forms are used as a scaffold sup port, the angle bars 13 may be positioned bars 13 which cooperate to tie together the spaced uprights 10.

Obvious modifications may suggest themiii) selves and to this end reservation is made to make such changes as may come Within the purview of the accompanying claims.

Havin thus described my invention, What is claimed is:

1. Convertible building form elements comprising a plurality of uprights, supporting plates secured to each upright and projecting from one face thereof and cooperating horizontal angle bars adapted to extend between spaced uprights and engaging said supporting plates whereby said uprights and angle bars may be disposed to support a scaffold platform or concrete form Walls.

2. Building form elements adapted for use alternately as scaffold support or concrete form Wall support comprising a plurality of uprights, slotted plate members rigidly secured to each upright and projecting from one face thereof and angle bars adapted to extend between spaced uprights and to engage said slotted plate members,

the position of said uprights and angle bars being reversible to adapt the form to its above-mentioned uses.

3. A building form element arrangement adapted for use as a scailold support or a concrete form Wall support comprising a plurality of posts, a plurality of plate mem bers secured in. spaced relation on each post, said plate members projecting from one face of said posts, and horizontal angle bars adapted to extend between said posts, said posts being spaced, and to engage Sillil plate members, the positions of said plate members being reversed in the above noted uses of said building form.

Building form elements adapted for use as a support for a scaffold platform and a concrete form Wall comprising a plurality oi"- uprights, a plurality of slotted metal plate members rigidly secured in spaced relation on each upright, said plate members projecting from one face of said uprights and horizontal angle bars adapted to extend between said uprights When they are spaced and to engage the slots of said plate members to reinforce said uprights, said uprights being reversible to vary the position of said plate members.

In testimony whereof, I aflix my signature.

DANIEL B. DANI'ELSON.
