REINFORCED HOLLOW BOARD.
Application filed May 3, 1918. Serial No. 232.397.
.intended Afor any structures in which it can be utilized, in 'no matter what position. This board or plank may be constructed either of plaster or of strong hydraulic cement, or else partly of plaster and partly of The accompanying drawing, given by way of example, shows two forms of the subjectmatter of the invention.
Figure 1 is a general View, in perspective, of the first form.`
Fig. 2 shows on a larger scale, also in perspective and in section, a portion of the board or plank illustrated in Fig. 1.
Fig. 3 shows sewn tubes or reeds in the position they occupy in theA portion of the plank shown in Fig. 2, before the manufacture of the plank.
Fig. 4 is a plan of ing for the manufacture of a as the one shown in Fig. 1.
Fig. 5 is a section through A -B in Fig. 4. Fig. 6 shows separately the part Z of. the mold shown in Figs. 4 and 5. Fig. 7 shows the second constructional form, and Fig. 8 is a section'through a mold serving vfor the manufacture of the plank.
Figs.I 9 to 12 show modifications in or connected with the reinforced hollow board, plank or the like, shown in the other figures. The plank shown in Fig. 1 is formed of tworeinforced parts a and b, connected together by a longitudinal rib c, the whole comprising a reinforcement of tubes or reeds plank such Z sewn into a sheet folded back upon itself like the cover of a book, as is seen 1n Fig. 3. The metal'wires e forming the stitching of the tubes or reeds, form a supplementary re'- inforcement which connects together the parts a and b. The metal wires e thus employed to secure the tubes or reeds together are of sufficient strength and' rigidity to maintain the tubes or reeds in the position shown in Fig. 3 or in other positions in which they may be placed in the mold so as to maina mold capable of serv-v tain these reinforcing members in the desired position while the body of the lblock is poured around the same.
The latter are maintained at the desired distance apart with respect to one another by the longitudinal rib c and by transverse ribs 7 integral with the parts a and b. These ribs f are pierced in the direction of their length with holes f which are intended to receive iron bars connecting together a series of similar planks, as. the string ofa rosary connects together the beads of the latter. The three full faces of the edge of the plank are provided with a groove g serving to form the joint with the adjacent plank, either by the insertion of a round iron-bar lodged partly in one plank and partly in the adjacent plank,- or by .pouring plaster or cement .into the hole and the specification of Letters Yatent. i Patented J 3.11. 27, 1920.
trated in Figs. 1 to 3, a mold of which one form is partly shown in Figs. 4 to 6, may
advantageously be employed.
This mold comprises a plank. h, assumed to be horizontal in the example illustrated. On this plank h forming the bottom of the mold is arranged a frame formed of the full sides `and Z6 and of a perforated side Z. A second side z' is not visible in Fig. 4, which is broken. The side Z of the frame is provided with openings Z for the passage of the cores m and holes Z2 for the passage of the rods r that serve to form the holes f in the ribs f.
The ribs f are formed by the space that separates two cores m from one another, and
in order that these cores may be able to be withdrawn from the plank easily after the latter has been cast, they are in the formof wedges. provided with a. nut n traversed by a screw o which bears upon an iron key p passing through an elongated aperture in the core and bearing on the bar Z. This device may be replaced by levers engaging in l(Sperings in the cores and bearing on the The plank illustrated in Fig. 7 differs from that of Fig. 1 by the fact that it comprises no longitudinal rib c.
Fig. 8 shows a mold serving for the manufactureof this constructional form. In this mold the `cores m pass through the two sides For the same purpose each core is Z and k of the mold,so that they can be easily extracted by striking lightly on the ends projecting from the side c 0f the mold.
The Iplank described in reference to Fig. 1, as Well as the one described in reference to Figi 7 may be constructed entirely of plaster, or entirely ofl cement, which envelopsl the tubes', reeds or the like, or by making one of the parts a or bof plaster/ and the other of cement. In the latter case hooks or cramp irons will be lodged in the mass, so as to connect together the plaster and the cement.
Thel improvements shown in Figs. 9 to 11, consist in providing such boards or planks with miter tongues h1 intended to enter and engage corresponding recesses in the ad- I claim.
A section of molded rectangular plank comprising spaced parts connected at one side. by a longitudinal rib and also connected by transverse ribs running at an angle to the longitudinal rib whereby there is formed an opening in the block bounded by the said ribs and extending from the said longitudinal rib to the opposite side of the plank, and afplurality lof spaced reinforcing tubes extending longitudinally of the plank and connected to one another by wires -running transversely through the members of the plankso that when in position, the reinforcing member is folded back upon itself like a cover on a book.
In testimony whereof I have affixed my signature in presence of two witnesses.
