JAY DARLING, OF WILLIAMSPORT, INDIANA.

MOLD FOR CONCRETE POSTS.

To all whom it may concern:

Be it known that I, JAY DARLING, a citizen of the United States, residing at Williamsport, in the county of Warren and State of Indiana, have invented a new and useful Mold for Concrete Posts, of which the following is a specification.

The object of my invention is to provide an improved post mold, in which a wire fas tener may be positioned before the concrete is poured, and embedded in the concrete and readily removed with the post as it is removed from the mold, whereby a considerable saving of time in making the posts may be effected; and to provide means for making a plurality of posts, having the heads of the posts facing in opposite directions in the mold; and to provide the novel combination and arrangement of parts hereinafter set forth and claimed. I attain the objects of my invention by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a top planof the invention;

Fig. 2 is a longitudinal vertical section on the line 22 of Fig. 1;

Fig. 3 is a transverse section on the line 33 of Fig. 1;

Fig. 4: is a perspective view of a completed P Fig. 5 is a perspective view of one of the mohl members detached from the frame; anc

Fig. 6 is a perspective view of one of my wire fasteners. v

Like characters of reference designate like parts in each of the several views.

Referring to the accompanying drawings,

I provide a frame for the mold members consisting of side frame members 1 and end frame members 2, the members 1 also being connected by intermediate frame member 3. Attached to end frame members 2, I provide mold supporting members 7 having U- shaped cut-out portions at to receive the large end of the molds, and 4 to receive-the small end of the molds. I provide tapered molds 5, of U-shape in cross section and having out turned flanges 6. Molds 5 are provided with slots 8 and adjacent apertures 9, spaced at regular distances apart, as illustrated in Fig. 5, and adapted to receive the free end 11 and loop of the wire fasteners 12, as illustrated in Fig. 2. Intermediate frame member 3 is provided with cut-out portions 4 of substantially uniform size to support the middle portions of the molds 5. The holes for the fastener are punched in when the mold is made.

In operation the wire fasteners are first inserted through. the slots 8 and apertures 9 of the molds 5, and then the concrete which may be suitably reinforced, is poured in the molds. When the concrete has hardened the set of postsfor siX are molded at a timeare removed from the molds, with the fasteners protruding as shown in Fig. 4. The side rails of the molds are preferably hinged in the center, for convenience in shipping.

lVhat I claim is: I

1. In a molding apparatus for the molding of posts from plastic material, the combination of a supporting frame, said frame including an intermediate frame member having cut out portions of substantially uniform size and the frame having a mold supporting member having U-shaped cut out portions to receive the ends of molds, these cut-out portions being alternately of large size to receive the large end of the mold and of-small size to receive the small end of the next adjacent mold, a plurality of reversely disposed tapered molds independently supported in and independently removable from the aforesaid supporting frame whereby any aarticular mold may be readily removed for disconnecting the fastening device or distributing other molds.

2. In a molding apparatus for the molding of concrete posts of plastic material, the

combination of a supporting frame, said frame including an intermediate frame member having cut out portions of substantially uniform size and the frame having a mold supporting member having U-shaped cut out portions to receive the ends of molds, these out out portions being alternately of large and small size to receive the end of the next adjacent mold, a plurality of reversely disposed tapered molds independently supported in and independently removable from the aforesaid supporting frame, the supporting frame being made of hingedly connected sections, to permit of compact collapsing of the frame for transportation when the molds are removed.
