Specification of Letters Patent.

Patented July 13, 1920.

Application filed June 8, 1918. Serial No. 238,811.

To all whom 711; may concern:

Be it known that I, EDWARD C. MARQUA, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Concrete- Form Supports and Brackets; and I do declare the following to be a full, clear, and

' exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to a concrete form and a supporting bracket for removably supporting certain releasable parts thereof as for example the form carrying stringers.

Heretofore an unnecessarily large amount of timber has been required to form con crete floors, arches and the like because the uprights and beams must remain in place for some time after the floor begins to set and because although stringers and form boards are not required they have been so tied in with the uprights and beams that they could not be removed.

It is one of the objects of my invention to provide means whereby the stringers and form boards can be removably supported by the beams and uprights so these may be removed shortly after the concrete is set, so that the sheeting may be used over again with another set of beams. It is also the purpose of my invention to provide an adjustable bracket support to accommodate cross beams of varying heights.

Other objects and advantages of the invention will be apparent by reference to the accompanying drawings, it being understood that changes in form and proportion may be made without departing from the spirit of my invention.

In the drawings: 7 Figure I is a'sectional perspective view of a form support and brackets constructed in accordance with my invention.

Fig. 11 is a vertical sectional view through the same.

Fig. III is an enlarged detail view of one of the brackets, and

Fig. IV is a detail perspective View of a slightly modified form of bracket.

teferring now to the drawings:

1 and 2 designate opposite sets of uprights supporting beams 3 and 4c. To the sides of the beams 3 and 1 are brackets 5 removably supporting the stringers 6 carrying the form boards 7 upon which the concrete 7 is placed. The form is here shown as flat although other forms may be employed if desired.

The preferred form of bracket is best shown in Fig. III as comprising a sheet of metal bent back upon itself to provide attaching beads S and 8 with openings 9 through which fastening devices such as nails 9 may be driven to fasten the bracket to the cross beams. The edges of the sheet terminate in outstanding wings 10 and 11 to provide a beam receiving space bridged by a removable beam rest 12 adjustable in the vertical rows of openings 13 and 1a in the wings 10 and 11 respectively. The rests 12 are designed to be vertically adjustable in the wings 10 and 11 to accommodate stringers of different heights and they will be held against accidental displacement by the keys 15.

When it is desired to set up the form the uprights and cross beams are erected in the usual manner and the brackets in place as shown. The rests 12 may be placed in the proper openings required for the particular stringers and the form boards 7 may be laid to receive the concrete 7 When it is desired to remove the stringers, and form boards the rests 12 will be removed in an obvious manner so that the stringers 6 may be dropped from between the wings 10 and 11 and at the same time the form boards 7 may be also removed leaving the uprights and beams to support the concrete structure until the same has suificiently set to safely effect the removal of the uprights and cross beams. In this manner the stringers and form boards may be used with other cross beams without waiting for the concrete structure to thoroughly dry.

The form of bracket shown in Fig. IV consists of a casting with the beads having inclined faces 17 provided with key-hole openings 18 to engage the heads of the fastening devices 9', thus the brackets may beads having perforations, to receive fastenbe easily removed after the stringers 6 are ing devices, the outer edges of the sheet beam 10 released. bent at right angles to the beads to form Having thus described my invention, What parallel wings, said Wings having alining 5 I claim as new therein and desire to seperforations and a stringer rest receivable cure by Letters Patent, is in pairs of alining perforations.
