This invention relates to improvements both to molds and floor structures, and it' consists oi the constructions; combinations and arrangements herein descrlbed and claimed.
An object of the invention is to provide a collapsible, reusable sectional mold to be Another object of the invention is to produce an improved reinforced concrete door of which the dome plates or slabs are important elements. I I
Other objects and advantages appear in the" following specification, reference being had to the accompanying drawings, ;in which Figure 1 is a perspective view of'a portion of a sectional mold'by mean'sof which joistsriinning at-r'ig'ht angles to each other may be constructed. I I

Figure 7 is a detail sectional "view showing a modified form of dome plate;
This invention is-an improvement on my patent on concrete molds #1,494l;538 granted May 20, 1924'. Some of the principles of the patented structure are repeated herein but the improved mold includes new features by which themolds' can not only beset up in a more practical manner but which will result" in the production of a better fioor.
Theforin o;t"tl1'e invention in Figures 1 and 2'- illustrates atypeof mold by means of whichjoistsrnnning at rlght angles to each other may be cast. Much of the struc- I concurs Mom).
Serial No. 70,383.
ture' in'Figures 1 and 2 appears inthe form of the invention in Figure" 3. Similar reference numerals are therefore employed to designate corresponding parts in order to avoid useless'repetition.
Boards 01 ' plates 1, 2, 3 and 4 outline a rectangular space when set in position edge on upon bottom plates 5,6, 7 and 8. Figure 2 partially illustrates the result of setting up anumb'e'r of the rectangles. Corresponding side plates have corresponding numerals; the resulting spaces 9 and 10 showing where the joists are c'astat right angles to each other.
The ends of the bottom plates 5, 6 T and 8 rest upon corner plates 11, 12', 13 and 1+1 in the manner substantially as shown in Figure 1. The corner plates provide-supports forcourses oflbottoln plates running in bo'th directions (F ig'. 2). Each of the corner plates" has projections 15 at the fourlcorners. These may consist simply of wooden b1ock's,- and'when set in' position as shown provide" guides'or channels for the bottom plates! V I Downward projections 16' on the under sides of the corner'plates provide grooves 17 for the supporting joists 18'. The various corner plates, upper projections 15 and lower projections 16'have registering holes 19 bored through for theflpurpose ofrece'iv ing nails 19 which are sumcie'ntly long to pin the upper projections" 15 upon the corner plates; The cornerprojections are intended to beloose; The nails 20 are easily reinovableto in turn permit removal of the corner projections. Thisfeaturetacilitates the disassembly of the form, I I
The upper edges of the side plates 1, 2, 3 and-t are beveled" at 24itoward the joist face. Previouslyprepared dome plates or slabs25 are set in' place upon the side plates, the rectangularspace defined bythe side plates is thus co'verediFigs. 5 and 6). The edges of the dome-plates are also beveled at 26. The purpose of the beveling of both the sideplates and dome plates toward the oist space is to prevent the dome-plates, pans or covers from slipping off the side forms, or the tops of the side forms from slipping from beneath the dome plates. Thus the weight of tee dome-plates serves as a clamp to hold the parts together. 7
Figure 7 illustrates the sides 39 of the dome-plate or pan as being beveled instead of rounded as in Figs. 5 and 6. The side forms are also shown as projecting beyond the edges of the dome-plate as at 40, this for the purpose of permitting easy removal of the. dome-plates. from beneath the cast structure after the side forms have been removed. This projecting feature of the side forms is also shown in Figure 5. Each dome plate has a number of wires 27 imbedded therein at 28 (Fig. 5) at a place substantially in the center. Short but large headed nails 29 are driven into the side plates 1, 2-, etc. and the ends of the wires 27 are wrapped around (Fig. 5) in order to hold the dome plates down in place. The Wires are later removed from the nails and are clipped close to the surface of the dome plates when finishing the job.
The modification in Figure 3 provides for casting joists running parallel to each other in one direction only. The reader will observe that the construction is practically identical with that already described, and as already stated, similar reference numerals are used to designate corresponding parts to avoid a repetition of description.
The side form boards 36 may be as long as necessary. These are spaced by plates 37. The spacer plates and form boards are braced and held by metallic angles 21 precisely as before. Referring to Figure 3, the reader will understand that a form board similar to 36 will be stood edge-on upon the pads 34. and upon the bottom plates 7 so as to define a longitudinal beam or joist space.
Upon reference to Figure 6 1t is to be noted that nailing strips 38 are incorporated in the form structure. These strips are laid crosswise upon the dome plates 25, and are intended for the purpose of permitting laying down a floor after the desired concrete work has been finished. Figure 6 also illustrates the use of transverse reinforcing elements 31 and This is laid in the grooves formed by adjacent dome plates.
The improvements may be briefly summarized. The corner projections or blocks are readilyremovable from the corner plates 11, 12, etc. by simply reaching up inside of the rectangle defined by the various side plates 1, 2, etc. and pulling out the nails 20 which are inserted perfectly loose. he removal of the corner projections 15 will in turn permit the ready removal of the bottom plates 5, 6, etc. The clips are molded in the concrete and are not removable.
A second feature of the invention appears in the dome plates 25. These are previously manufactured, whether of wood, metal, plastic or cement, being either rounded or beveled at the sides, and are incorporated in the form. In this capacity they act as covers of the rectangular spaces defined by the side plates, but when the form is disassembled these dome-plates are removed because one of the purposes of the invention is to permit re-use of all parts. p
While the construction and arrangement of the improved concrete mold is that of a generally preferred form, obviously, modifications and changes may be made without departing from the spirit of the invention or i the scope of the claims.
I claim 1. A mold comprising a bottom plate, corner plates upon which the ends of the bottom plate are supported, means on the corner plates to form passages to receive said ends, and means holding said passage-forming means in temporary position permitting ready removal thereof upon disassembling the mold.
2.

V
3. A mold comprising a pair of plates including corner plates, means underneath of said plates providing passages and constituting guides for supporting structure, a bottom plate, the ends of which are laid upon said first plates, means placed upon said first plates forming passages to receive said ends there being registering openings in said passage-forming means, first plates and guide means, and means including nails dropped into said registering openings to temporarily secure said passage forming means in position.
4. A mold comprising a bottom plate, side plates, set edge-on upon said bottom plate to define a joist space, dome plates applied to tie upper edges of the side plates leaving said joist space clear, and bevels along the adjoining edges of the dome and side plates being contactible to prevent the dome plates from slipping off of the side plates or the slide plates from under the dome plates.
5. A mold comprising a bottom plate, side plates set edge-on upon said bottom plate defining a joist space, dome-plates, and bevels along the confronting edges of the side and dome plates tending to maintain the parts in place by virtue of the Weight of the dome plates.
