To all whom it may concern:

Be it known that I, WALTER P. Aonnss, a citizen of the United'States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Metal Connections for Beam and Girder Molds; and I do hereby 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 the drawing.

it appertains to make and use the same.

This invention'relates to new and useful improvements in metal connections for beam and girder molds and the principal object of the invention is to provide a device particularly adapted for" use in connection with poured concrete construction to prevent the liquid concrete from flowing out of the forms at the joints.

Another object of the invention is to-provide a device which will enable the forms to be readily wrecked after the concrete has set.

Still another object of the invention is to provide a device which is adjustable in the beam form so that slight variations in the distances between girders may be taken up by the sliding into or out of the beam form this improved connection.

A further object of this invention is to enable the device to be used without providing various lengths of beam forms in connection with columns which reduce toward their upper ends as the connection may be adjusted to compensate for the variations of length of space.

With these and other objects in view this invention consists in the novel combination and arrangemnt of parts which will be fully set forth in the following specification and acompanying drawings, in which Figure 1 is a fragmentary perspective view of this improved connection attached'thereto. Fig. 2 is a longitudinal sectional view through the device illustrated in Fig.1.

Fig. 3 is a detail-perspective view of the connection, and Fig. 4 illustrates the device in use, in molding beams showing the same compensating for the varying thicknesses of columns.

Referring to the drawings, the'numeral 1 designates the bottom of the connection which rests in the bottom 2 of. the beam mold. The sides 3 are formed integral with the bottom 1 and extend upwardly therefromlying against the inner faces of'the a beam and girder mold showing Specification of LettersPatentu Pafentd J 1y 18, 1916 Application filed November 17,1915. Serial no. 62,044.

flanges 5 are formed at the upper edges of the side walls 3 and engage on the upper edge of each side wall4 of the beam mold or form to prevent the liquid concrete from flowing down between the walls 3 and 4. Formed at the inner ends of the walls 3 are the outturned wings or flanges 6, the upper edges of which are formed with the flanges 7, which conform to the flanges 5asclearly shown in adapted to engage the side wall Sjof the girder form designated generally by the numeral 9 and formed on the bottom1 of the connection is a down-turned flange or wing 10 which engages the wall of the girder form 9betweentheupper edge of the' recess in which the connections seat and thebottom V 11thereof.-'

The beam form is designated generally by the numeral 12 and it will be seen that the necessity of making a tight fit between the ends of the beam form and the sides of the girder form is eliminated, as the con-, nection will prevent the material from flow ing out of any crack which may be left therein. It is to'be understood that if so suitable nails may be' driven wings 6 and 10 of the connecfirmly hold the same against desired, through the tion so as to accidental movement process of the construction.

As shown in Fig. 4, it will be seen that the column mold is designated. by the numeral 13 and the inner-wall 14 thereof is provided with the openings for the reception of the connection andv saidconnection is placed in the opening in the same manner as it is placed in the recess in the girder mold. It

-will be. seen that thebeam mold 12 is supported on suitable cleats 15 secured to the outer faces of the girder and'column mold and when the concrete is set and it is desired to remove the vmold, the cleats 15 are removed, thus permitting'the' beam forms to during the pouring.

The wings or flanges 6" are drop away from the finished work, thus facilitating the wrecking of the form. It

will be noted upon reference to Fig. 4 that I the. cleat 15 for supporting'the beam mold 12 at the upper end of the column is. preferably supported ont a suitable bracket 16 so as to insure the proper" positioning of the beam mold regardless of the amount of reduction of the thickness of the column.

From the foregoing, it will, be apparent that a particularly simple and eflicient c0nnection is formed which will prevent any loss of the concrete, due to its flowing through any openings left between the joints of the mold and also the possibility of the material flowing into the device between the mold and the connection is eliminated as the flanges 5 and 7 will serve to prevent this.

While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that such changes may be made in the com bination and arrangement of parts as will fall within the spirit and scope of the appended claims.

What is claimed is:-

1. In a concrete mold, a beam form and a girder form, a metallic connection comprising a bottom, side walls formed integral therewith, said bottom and side walls being adapted to fit within the beam form and outturned flanges at the ends of the bottom and side walls adapted to fit the side wall of the girder form to form a tight con nection between the girderand beam form.

2. In a form for concrete construction, a girder form and a beam form, a connection Copies of this patent may be obtained for five cents each, by addressing the comprising a bottom, upturned side walls on the bottom, flanges at the upper edges of the side wall, said flanges being turned outwardly, the connections being adapted to seat within the girder form so that the flanges at the upper ends of the side walls engage the upper faces of the side walls of the beam forms, wings at the inner ends of the side walls and of the bottom, said Wings being adapted to engage the inner face of one of the side walls of the girder form and outturned flanges'at the upper edges of the Wings on the side walls, said flanges being adapted to overlie the upper faces of the side walls of the girder form to cooperate with the first mentioned outturned flanges in preventing the concrete poured into the molds from passing between the form and the connection.

In testimony whereof I aflix my signature in presence of two witnesses.
