UNITED, STATES PATENT o Fics PANEL roa MOLD WALLS Application filed January 26, 1329. 'Serialiio. ,212.

The present invention pertains to a novel panel used in assembling the wall of a mold into which concrete is to be poured.

The principal object of the invention is to provide a panel of this character which, when used in conjunction with aseries of like panels, provides leak-proof joints at the abutting edges of contiguous panels. \Vith this object in view the panel; is provided. with fiat strips secured at certain edges thereof and projecting beyond the same,while at the remaining edges are secured so-called receiving strips set back from these edges and spaced from the general plane of the panel except for the points of connection thereto. The panels are assembled in such a manner that the projecting strips of one unit are received beneath the receiving strips of the adjacent units. i

Another object of the invention is to prevent the device from becoming useless when concrete collects and sets beneath the receiving strips. The points of connection between the panel proper and the receiving strips are spaced from one another, so that the entire receiving strip is spaced from the panel except at such points of connection. Thus,

when a projecting strip is inserted with some force beneath a receiving strip, any concrete which may have accumulated under the latter will be thrown out at the inner edge of the receiving strip.

The invention is fully disclosed by way of example in the following description and in the accompanying drawing, in which- Figure 1 is a plan View of a panel accord ing to the invention;

F'g. 2 is a sectional View of an assembled mold t Fig. 3 is an edge view of the panel;

Fi 4 is a detail section of a joint between panels; a

Fig. 5 is a detail sectional view of an irregular wall; and i Fig. 6 is a detail section of a modifiedjoint.

Reference to these views will now be made by use of like characters which are employed to designate corresponding parts throughout.

The body of the panel consists of a metal sheet l,.or even a board, of rectangular or other desiredshape. At two of theadjacent edges are secured flat strips 2 which project beyond such edges as clearly shown in Figures 1, 2 and 4. The attachment maybe made by welding for example as indicated by the weldspots 3. i j j At the remaining edges of the panel are secured so-called receiving strips 4 in such a. manner as to be generally spaced from the" surface ofthe panel. Attachment inthis manner is made possible bystriking depressions 5 at intervals along the strip and scour ing these depressions to the panel by welding as indicated by the weld spots 7 The receiving strips are set had: slightly from the edges at which they are secured,and the outermost edges otthe strips arepreferably bent slightly away from the panel as indicated by the numeral 8, for a purpose which will presently appear. 7 j

When aniold wall is assembled from such panels, they are arranged so that the pro cated by the numeral S), andwhe'n these edges are brought together, the projecting fiat strips 2 pass beneaththe outer edges of the receiving strips'4 as shown more clearly in strips facilitate entry of the projecting strips.

The abutting edges of the panels 1 may, however, be cut square as at 9 in Figure 6 to form a simple butt ]O1Ilt.

Figure 4} The bent edges 8 of the receiving" Due to the almost complete spacing of the a strips 4 from the panel, any concrete which may have accumulated beneath these strips in previous use may be. broken loose by a forcible insertion of the strip 2, whereupon the loose chunksot material are enabled to fall away'by passing beneath the inner edges of thestrips. It will be evident that such release and expulsion of accumulated material would not be possible if the strips 4 were not spaced almost entirely from the respective panels.

In Figure 5 is illustrated a construction wherein the mold wall has dihedral angles.

Via

Such angles are formed by providing angular projecting strips 10 at one of the sides 11 thereof in such a manner as to be inserted beneath receiving strips 12 secured to the panel 13 constituting the other side of the angle, in the manner already set forth.

Although specific embodiments of the invention have been illustrated and described, it will be understood that various alterations in the details of construction may be made without departing from the scope of the invention as indicated by the appended claims.

IVhat I claim is 1. In a panel for a mold Wall, a strip secured at an edge of said panel, and a receiving strip secured to another edge by means of spacers, whereby said receving strip is spaced from said panel, said spacers being spaced from each other.

2-. In a panel for a mold wall, a strip secured at one edge of said panel and projecting from said edge, and a receiving strip secured by means of spacers at another edge of said panel, whereby said receiving strip is spaced from said panel, said spacers being spaced from each other, and said receiving strip being set back from the edge at which it is secured.

3. In apanel for a mold wall. strips secured to said panel at two adjacent edges thereof, and receiving strips secured by means of spacers at the remaining edges of said panel, said spacers being spaced from each other.

4. In a panel for a mold wall, strips secured to said panel at two adjacent edges thereof, receiving strips secured by means of spacers at the remaining edges of said panel, said spacers being spaced from each other, said first named strips projecting beyond the edges at which they are secured, and said receiving strips being set back from the ed es at which they are secured.

5. In a panel for a mold wall, a strip secured at an edge o1 said panel, and a receiving strip having spaced projections extending toward said panel and secured at another edge of said panel, whereby the major portion of said receiving strip is spaced from said panel.

6. In a panel for a mold wall, a strip secured at an edge of said panel, a receiving strip having spaced projections extending toward said panel and secured at another edge of said panel, whereby the major portion of said receiving strip is spaced from said panel, said first named strip projecting beyond the edge at which it is secured, and said receiving strip being set back from the edge at which it is secured.

In testimony whereof I afiix my signature.

FRANK J. GREMEL.
