This invention relates to concrete forms and structures, especially adapted for making walls and the like, which can be very readily constructed and which can be enlargedat will,

without destroying the parts already erected. I By this invention greenhouse beds, walls, fences, etc., of different sizes can he made of concrete, without requiring an inordinate amount of equipment. This application is a w division of my application Ser. No. 111,724,

filed May 26, 1926.

The forms that are used in making the different devices can be removed and reused for making others, or for enlarging those already made.

My invention will be understood from the description in connection with the accompanying drawing in which Fig. 1 is a perspective view of a greenhouse bed made in accordance with this invention; Fig. 2 is a horizontal section showing the forms in place;

Fig. 3 is a side elevation of the forms, partly broken away; and Fig. 4 is a perspective view of the form. V

In the drawing reference character 1ndicates posts that may be made at any convenient location and set in place in the ground or in concrete at suitable distances apart, or these posts 10 may be made in situ by pouring concrete into forms adapted forthat purpose.

The posts 10 are made with the inside and. outside faces thereof flat and parallel to each other, and the other faces are provided with longitudinal grooves 11 that have converging sides and extend from the top of the posts and terminate at the level of the ground when the posts are in place.

A plurality of rods 12 (Fig. 2) extend between the posts in vertical planes, and their ends project into holes in the grooves 11 that are provided therefor. Flat plates 13, most clearly shown in Fig. 4 are placed beween the posts 10 and are spaced apart distances corresponding to the desired thickness of the clearly shown in Fig. 4 are placed between the posts. The plates 13 are provided along their upper edges with outwardly extending flanges 14. The lower inwardly extending flange 16 of one of the plates 13 is made wide enough to extend a short distance beyond the outside of the other plate which is provided at its lower endwith a narrower outwardly extending flange 15, whose outer edge is flush with the edge of the flange 16 when the plates 13 are spaced theproper distance apart. In order to keep the plates 13properly spaced, the flanges 15 and 16 are provided with holes into which pins 24 may be inserted, thus preventing the plates from spreading at the bottom whenthe concrete is poured in. Y

*U-shaped clamps '21 may be providedyfor pressing the plates 13 toward each otherand holding same in position. The clamps 21 are provided with thumb screws 22 to enable the same to be tightened against the plates. If .5

desired, pressure plates 23 (Fig. 2) may be inserted between the lower ends of the'clamps -21'and the sides of the plates 13.

.Auxiliar-y plates 25 are provided to be placeda-gainst the inner and outer faces of the posts 10 to aid in keeping the plates 13 in place.- The plates 25 are provided with inwardly extending flanges 26 at their upper ends, with inwardly extending flanges 27 along their sides and with flanges 28 at right angles to the flanges 27, thus enabling the plates 25 to'be' placed upon the sides of the .post 10, with't-he flanges 26 resting on tops of the posts, and with the flanges 28 extending longitudinally ofthe space between the posts, and with the flanges 14 of the plates 13 resting'upon theupper ends of theflanges 28,

While the plates 13 themselves are in contact with the sides of the flanges 28. Clamps 21 similar to the clamps 21, are provided for retaining the'plates 25 in place against the sides of the posts 10. The depth of the flanges 27 is preferably mad'e such that the plates 13 will be flush'with the edges of the grooves 11, thus makingthe' thickness of the concrete slabs" between the posts 10 considerably less than the thickness of the posts themselves.

Instead of holding the plates 13 with clamps 21-to prevent them from spreading,

as above describechthese plates may be provided with holes through which wire, for ex ample, may be passed as shown at 29, the ends of the Wire being twisted together to exert tension thereon. The wires may be clipped m after the concrete has set, in order to remove the plates. The use of the wires to hold the plates in position is especially desirable with wide plates that would require the employ- 5 ment of clamps with long shanks to hold them.

I claim:

1. In a concrete form, a plate having flanges along its opposite edges, and a second plate having flanges, one of which extends under one of said first named flanges and in contact therewith, the flanges of said first named plate extending in the same direction and the flanges of said second named plate extendingin opposite directions;

2. In. a concrete form, a plate having flanges along its opposite edges, and a second plate having flanges, one of which extends under one of said first named flanges and in contact therewith, said second plate having an outwardly extending flange at the upper portion thereof.

3. In a concrete form, a plate having flanges along its opposite edges, 3. second 2 plate having a flange extending under one of said first named flanges and in contact there with, the flanges of said first named plate extending in the same direction and the flanges of said second named plate extending 3 in opposite directions, and holding members passing through said plates to prevent them from spreading apart.

4. In a concrete form, a plate having flanges along its opposite edges, a second plate having a flange extending under one of said first named flanges and in contact therewith, and means to prevent said flanges from moving in a plane parallel to said flanges.

, 5. In a concrete form, a plate having 40 flanges along its opposite edges, a second plate having a flange extending under one of said first named flanges and in proximity thereto, and pins passing through said last named flange and one of said first named flanges to prevent them from moving sideways.

6. In a device of the character described, posts spaced apart, spaced plates between said posts, and plates extending along the sides of said posts and having edges overlapping the ends of said first named plates.

7. In a device of the character described, posts spaced apart, spaced plates between said posts, and plates extending along the sides of said posts and having edges overlapping the. ends of said first named plates, said second named plates having flanges extending along the edges of said posts.
