COMPOSITE BUILDING MATERIAL.
SPECIFICATION forming part of Letters Patent No. 750,456, dated January 26, 1904. Application filed January 24, 1903. Serial No. 140,386. (No model.)
To all whom, it may concern.-
Be it known that I, RUDOLPH HARTMAN, a citizen of the United States, and a resident of Madison, in the county of Dane and State of Wisconsin, have invented certain new and use ful Improvements in Composite Building Material; and I do hereby declare that the following is a full, clear, and exact description thereof.
My invention relates to composite building material particularly designed to resist compression; and to that end it consists in certain peculiarities of construction, as will be fully set forth hereinafter in connection with the accompanying drawings, and subsequently In the said drawings, Figure is a plan view, partly in section, of a column embodying my said invention; and Fig. 2 is a view, partly in elevation and partly in section, of the same.
My building material consists of concrete of any known and preferred composition, in which are embedded longitudinal metal cylinders, the latter being formed with openings of any desired number through the walls thereof, and preferably these openings are formed by punching the metal outwardly, so as to leave same in tongues or roughened projections, and in the practical manufacture of said building material the said metal cylinders are supported vertically within molds of proper form, and the concrete is forceddown to place both inside and outside of the said cylinders, (of which one or more may be employed in any given instance,) so that when each section of the material is completed it will present an exterior surface of concrete of any desired form. In the illustration given a column is represented, and hence the finished section would be cylindrical; but this is immaterial, as same might be a square or other form of building-block, if desired,with one or more of the said metal cylinders embedded therein, or there may be a wall of concrete with the said cylinders embedded at intervals therein, just as preferred in any given instance.
Referring by numerals to the drawings, 1 represents the central body of the concrete, and, as in the present illustration two metal cylinders are shown, 2 designates the next vertical portion of concrete, and 3 the outer portion of concrete, the inner cylinder between the portions 1 and 2 of the concrete being marked 4 and the cylinder here shown between the portions 2 and 3 of the concrete being marked 5, all of the concrete being forced in at the same time from the top of the mold in the manufacture of the said composite building material. In the preferred form herein illustrated there are shown a number of openings 6 6 in each cylinder, which are punched out to form the tongues or rough-.
ened projections 7 7 7, which serve to hold the said cylinder in close union with the adjacent mass of concrete into which they extend, the said concrete also filling the said opening 6 6, so that when completed the sections of building material form solid masses, with the concrete and metal cylinders inseparably united. If desired in any instance, the described projections or certain of them may be punched so as to extend inwardly, this being a matter of choice or convenience in the manufacture of the said cylinders, which latter are preferably of steel.
It will be understood that whether there be one or more steel or other metal cylinders embedded in my building material it is always essential that the exterior surface of the same should be concrete and not metal and that the said concrete should form a solid mass which should not be completely interrupted at alLpoints between the inner and outer portions thereof by any metal cylinders embedded therein.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. A composite building material, comprising a solid mass of concrete, having a metal cylinder embedded therein, the walls of said cylinder having tongues or projections punched therefrom, and with the concrete filling the openings thereby made, and at every point inseparably united to the said cylinder.
2. A composite building block or column, designed to resist compression, comprising a solid mass of concrete having a metal cylinder embedded therein, said cylinder being formed with tongues or projections punched therefrom, leaving perforations in the cylinderwall, and With the concrete filling the said perforations, whereby the said concrete on each side of the said cylinder will be continuously united at the points of said perforations, and both surfaces of the said cylinder be everywhere in contact with and completely covered by the said concrete.
3. A composite building block or column, designed to resist compression, comprising a' solid mass of concrete, having a metal cylinder embedded therein,the wall of said cylinder being perforated at intervals but the metal of said cylinder being otherwise continuous, and
cylinder, on both sides thereof, at every point.
In testimony that I claim the foregoing I have hereunto set my hand,at Milwaukee, in the county of Milwaukee and State of Wisconsin, in the presence of two witnesses.
RUDOLPH HARTMAN.
