Wissinger, Juniata Gap, Aitoona, Pa. Application July 2, 1954,.Serial No. 441,060 2 Claims. (Cl. 25-421) This invention relates to molds for forming concrete blocks and other units of any other suitable materials, such as wood fiber with plastic binders, insulation, and gypsum, for use primarily as structural units in building construction, and in particular, a frame having multiple areas therein in which the frame-is adapted to be removed after concrete blocks or units are cast in the areas.
The purpose of this invention is to provide means for casting blocks and other units adapted for use in building construction and the like in which the units are adapted to be cast in tiers with frames for separating the units progressively moved upwardly as the blocks or units are formed.
Concrete blocks and units of other patterns such as used in floor and roof slabs, beams, walls, paving units and the like are cast in molds and for quantity production a plurality of molds are used. It is sometimes difiicult, however, to remove pre-cast concrete blocks or other forms from molds without chipping corners or edges of the blocks or without damaging surfaces thereof. With this thought in mind, this invention contemplates progressive forms or molds whereby blocks or other units are adapted to' be cast in tiers with the blocks remaining in the tiers in which they are cast until they are required for use.
Theobject of this invention is, therefore, to provide a collapsible form particularly adapted for casting blocks, beams; arcuate and triangular-shaped shapes whereby'one unit is cast upon another of the same pattern and size and wherein the forms are adapted to be removedand reused to cast superimposed units.
Another object of the invention is to provide a collapsible form for casting building and-facing blocks and other concrete units in which the form is readily assembled and also in which the form is'readily taken apart.
A further object of the invention is to provide acollapsible form for casting individual concrete blocks-and units in which the form is of a comparatively simpleand economical construction.
With these and other objects and advantages in view, the invention embodies spaced tubular longitudinally and transversely positioned members clamped in assembled relation with rods having nuts on"th'rea ded ends thereof wherein with the frame'horizontally disposedon a flat surface areas between the memberslare' positioned to receive concrete and units formed in said areas are provided with concave edges to facilitate framing the units in floor and roof slabs, Walls, beams and the like. The frames being clamped together with nuts on threaded ends of rods, are readily taken apart by removing the nuts and withdrawing the rods.
Other features and advantages of the invention will appear from the following description taken in connection with the drawings, wherein:

Figure 9 is a perspective view illustrating one of the arcuate slabs formed by the molds shown in Figure '7.
Figure 10 is a plan View also similar to that shown in Figures'l and 7-and also with parts broken away, illustrating a method of positioning members of the molds to form triangular-shaped blocks or units.
Figure 11 is a detail illustrating theuse of sand as building material in openings between units formed by the molds.
Figure 12 is a perspective viewillustrating a block or unit formed in the center of the frame or mold shown in Figure 10.
Referring now to the drawings wherein like reference characters denote corresponding parts, theimproved multiple form for casting concrete blocks and units in cludes side beams 10 and 11 intermediate beams 12', transversely disposed end-beams l3- and 14, transversely disposed intermediate beams 15 and 16, rods 1-7 extended through the transverse and longitudinally disposed beams and having threaded ends18-on which'nuts 15 are positioned andconnecting plates 20having slots 21 and 22 extended inwardly from the ends and adapted to be positioned with the rods 17 extended through the notches, as shown in Figure 4.
To form two-inch blocks or units, two-inch pipes or tubes are used to-form the frames and the ends the longitudinally disposed tubes are threaded, as i heat"? by the numeral 23, whereby tubes or pipes for steam into the material of the blocks may readily be connected to the members'of'the' frames.
Longitudinally disposed members are provided with notches 24 which are spaced to correspond with the size of blocks or units to be formed in the mold and, as illustrated in Figure 3, the rods 17 extend through the notches. Longitudinally disposed members may be provided with notches spaced at different distances and these may readily be assembled with the plates 20 extended across two of the molds or frames.
The transversely disposed members are provided in sections and the ends of the sections may be straight, however, it is preferred to provide arcuate surfaces on the ends to correspond with the surfaces ofthe longitudinally disposed members, as illustrated by the arcuate surfaces 25, in Figure 1.
The inner surfaces of the longitudinally disposed members may also be perforated so that steam may be injected into the material of'the blocks or units and it will also be understood that air or other fluid may be injected in the units to facilitate drying or hardening.
With the forms, as illustrated in the Figures 1, 2 and 3, blocks or units 26 having arcuate edges, as indicated by the numeral 27, are formed and with the units formed in tiers the blocks or units are separated with layers of a suitable non-binding material, such as building paper, sand and the like, as indicated by the numeral 28.
In the design illustrated in Figures 7, 8 and 9, arcuate longitudinally disposed members 39 held by transverse members formed with sections 31 which are positioned between the members 30, and end sections 32 are retained in position with the rods 33 having nuts 34 threaded on the ends and these units are also provided with tie plates 35, similar to the plates 20. The longitudinally disposed members 30 are also provided with threaded ends 36 to facilitate connecting steam hose or pipe thereto. By this means arcuate blocks or units, as indicated by the numeral 37, are formed and the edges of the units 37 are also provided with concave or arcuate edges 38.
In the design illustrated in Figures 10, 11 and 12, a form for triangular-shaped members is provided in which angularly disposed longitudinal members 39 and 40 are positioned between side members 41 and 42 and the members are retained in position with spaced elements 43 similar to the transversely disposed members 13, 14, and 16 of the mold shown in Figure l. The members 43 are provided in different lengths to correspond with the distances between the members 39 and 4t) and between these members and the side members 41 and 42.
This frame is also retained in assembled relation with transversely disposed rods 44 with nuts 45 and tie plates 46 on the ends. The unit illustrated in Figure 6 and as indicated by the numeral 47 shows a typical block and in comparing this unit with the mold shown in Figure 10 it will be understood that blocks of different shapes and designs may be formed between the side and end members.
In use, a form, such as illustrated in Figures 1, 7 and 10, is assembled on a flat surface and the areas between the members filled with concrete with the concrete extending from the flat surface to a plane corresponding with upper surfaces of the side and end members. By this means, units, as illustrated in Figures 6, 9 and 12, may be formed and as one layer of units is formed the frame of the mold is taken apart, the upper surfaces of the units covered with a sheet of material, or with a non-binding substance, and the frame set up to form the next layer.
It is preferred to supply these frames in pairs whereby a frame for a lower layer of units supports a superimposed frame, as illustrated in Figures 2 and 3, and, as shown in Figure 4, upon removing the lower frame, the frame removed is positioned on the upper frame as indicated by the broken lines and the tie plates turned over as shown by the dotted lines. By this means, a frame taken from below is positioned upon a superimposed frame, and by this means, the units are formed in tiers with each layer of units separated by a non-binding material.
As stated before, the units are adapted to be used in forming walls, floor and roof slabs, beams, paving columns and the like.
It will be understood that modifications, within the scope of the appended claims, may be made in the design and arrangement of the parts without departing from the spirit of the invention.
