T 0 all whom it may concern i Be it known that l, JAMES ll. Jones, a citizen of the United States, residing at Washington, in the District of Columbia,

have invented certain new and useful lmprovements in Concrete-Molds, of which the following is a full, clear, and exact description.

This invention relates to structures tor molding concrete, cement, and the like, and has for its object to provide such a structure with means for suspending the side plates and thereby avoid the use of a base member.

A further object of the invention is to provide such a molding structure that the upper surface oil the concrete will be spaced from the molding apparatus in order that such surfacemay be troweled finished while the apparatus remain its original position.

Another object of the invention to pro vide a mold. which may be used for laying either curved or straightcurbing.

Uther objects and advantages of i: vention will be apparent 'from the folio-win description when taken connection witl the accompanying drawing, in which igure 1 is a transverse section through the apparatus- Fig. 2 is a longitudinal section therethrough. a

3 is a detail section shawing a portion of the mold removed.

Fig. 4.- is a plan view.

Fig. 5 is a section through a slightly modilied form;

Fig. '6 is a section through another modification; and,

Fig. 7 is a detail plan view of an improved brace member.

Referring to the drawing more in detail,

and particularly to Fl s. 1 to t, inclusive,

the supports comprise t e stakes 1 and horizontal brace members '2. Connected to the brace members 2 and depending therefrom are a plurality of hangers 3. llhe hangers 3' are arrange in pairs and may be clamped against outward movement by means or the bolts 4 located adjacent the top and bottom of the brace member 2. Side plates 5 are secured to the hangers 3 and have attached to their outer faces the horizontally disosed reintorcin members or plates 6. rackets may e interposed between the side plates 5 and the reinforcing members 6.

' In operation, the apparatus is arranged as shown in Figs. 1 and 2, and the concrete is poured in the usual manner. By having the side plates suspended as shown, it is unnecessary to provide a base for these plates, such however, is almost always necessary when using the old method, especially when working in soft or muddy ground.

As shown in big. 3 oi the drawing, a side plate may be removed by merely loosening the bolts l and removing the nails pass ing into the brace member 2; the face of the curb or other part being formed is then to be finishe any manner desired. order to retain the remaining plate in position l provide the stake 8.

In ig. 5 is shown an apparatus for mold ing wall copings. ln this form of the invention the supports including the stakes l and braces 52 dispensed with, and the hangers are clamped wall by means oat bolts ig. 6 shows a structure "for molding combined. curb and gutter, and is substan tially the same as the construction shown in i to 4t inclusive with the exception that the side plate 5 is somewhat shorter than plate 5 so as to provide space for the Furthermore, a secondary plate 5 is supported in position by means of the stakes l, to form the edge ot the gutter.

In Fig. 7 l have shown a form oi: reinforcing member 6, which may be used either tor curves or "for straight work as may be desired. 'lo this'end the plate is provided with a curved edge and a straight edge. This plate may be en ported from the hangers 3 with its curve edge facing inwardly or may be reversed it straight curbing is to be laid.

In accordance with the patent statutes 1 have described What ll now believe .to be the best embodiment of the invention, but ll do not wish'to be understood thereby as limiting myself or the scope of the invention, as many changes and modifications may be made Without departing from the s irit of the invention, all such ll aim to inc ude in the scope of the ap ended claims.

What ll claim as new and esire to secure by Letters Patent is:

l. A concrete mold including a plurality of stakes, transverse brace members connecting pairs of stakes, hangers rigidly con- Bil) llltl I nected with and depending from said brace 3. A concrete mold includin a support,

members, and slde plates connected to said side plates connected therewit and reinhangers. v forcing mem bers connected to said plates, 10

2. A concrete mold including a sup ort, said remforcing members having a straight 6 hangers depending therefrom, side p ates edge and a curved edge.

secured to said han ers, and one ormore bolts connecting sai hangers. JAMES I. JONES. J
