ADJUSTABLE MOLD FOR REINFORCED CONCRETE CONSTRUCTION.
SPECIFICATION forming part of Letters Patent No. 779,319, dated January 3, 1905.
Application filed November 14, 1904. Serial No. 232,624.
30 ctZZ whom it may concern:
Be itknown that LJoHN O.RUssELL,a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Adjustable Molds for Reinforced Concrete Construction; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
My invention relates to the class of molds employed in what is known as reinforced or armored concrete-construction work for the formation of columns, beams, and the like; and it has for its object to provide a mold of this class that is simple and durable in its construction, easily adjustable for the formation of columns and beams of different sizes and shapes, and readily knocked down after a formed mass has sufficiently hardened Without destroying the parts thereof, thereby rendering the same mold capable of repeated use for the same character of work.
The invention is fully described in the following specification andshown in the accompanying drawings, in which Figure 1 is a transverse sectional view of a column-mold embodying my invention. Fig. 2 is a central vertical section of a portion of a column-mold, taken on the dotted line 0 m in Fig. 1. Fig. 3 is a side elevation of a portion of a column-mold, and Fig. 4 is a crosssection of a mold adjusted to form a rectangular column.
Referring to the drawings, A represents the four plates or vertical pieces forming the sides of my mold, and B the binding or girdle irons for retaining the side plates A in rigid adjustment. The binding or girdle irons B are each preferably formed of angle iron and are longitudinally bent into L shape to form the integral arms a and I), which are strengthened by a brace or web 0, that is riveted or otherwise securely fastenedto the horizontal flanges of said arms. Provided longitudinally of the short arm 6 and the outer ends of the long arm a in the vertical flanges of each of the girdle-irons B are bolt-receiving slots (Z and cl, respectively, which are adapted to permit of the lateral adjustment of the sides to form a mold of the desired size, as hereinafter described.
The side plates or boards A are of uniform width and height, and each is provided at its upper and lower ends with one or more slots 6, adapted to seat over pins f, projecting from the inner faces of the vertical flange of the portion a of each girdle-iron, as shown. The plates A are also provided with a series of bolt-receiving apertures g, that are positioned to aline with the slots (Z and (Z of the connected girdle-irons B when the parts are assembled as shown in the drawings.
A column-mold when set up comprises a series of superimposed sections, as shown in Fig. 3, the number of which depends upon the height to which the column is to extend. Each of said sections is composed of four side plates A, positioned at right angles to each other in the form of a quadrangle and each having a side edge abutting against the inner face of one plate with its opposite edge passing beyond the side edge of the next contiguous plate, as shown in Figs. 1 and 4:. Secured in flush position at the upper and lower ends of each plate A is a girdle-iron B, which has the pins f thereon projecting within the slots 0 in the plates to prevent lateral movement thereof and its short arm 6 bearing against the projecting side of the adjacent side plate in parallelism with the end of the portion a of the girdle-iron secured to said latter plate. The several plates and attached girdle-irons of each section are adjustably secured together by means of the bolts h, which pass through the alining slots (Z and (Z of the contiguous portions of the connected girdleirons and one of the apertures g in the interposed side plate. The girdle-irons B at the upper and lower ends of the plate A are so arranged that the vertical flanges thereof converge or extend in relatively opposite directions from their horizontal flanges, thereby enabling the horizontal flanges of the girdleirons disposed at the contiguous ends of the abutting sections to bear upon each other and be securely fastened together by retainingbolts 2'. In this manner each superimposed section of a column is made an integral part of the next abutting section, as shown in the drawings. In the lateral adjustment of the side plates to form a column of the desired size and shape it is only necessary to loosen the adjusting-bolts lb and position the plates as the specification of the column to be formed may require, the bolts being then tightened to lock the parts against movement. If it is desired to adjust the mold to 'a size larger than shown in Figs. 1, 2, and 3 of the drawing, the same may be accomplished by positioning the adjusting-bolts in one of the other bolt-receiving apertures g in the plates A, thereby permitting a further outward movement of a girdle-iron with respect to the plate to which its short arm 6 is connected.
It is apparent from the above description that my invention comprises a mold that may be built up in sections, thus enabling the concrete to be deposited in each section before the next superimposed section is added there- -to, a feature that is most important in the proper formation of a structure of this class, inasmuch as it is quite necessary for the workmen to see that the concreteis being properly packed around the reinforcing-rods and also that may be easily knocked down after the concrete has sufiiciently hardened and repeatedly used for the same class of work.
It is obvious that such changes in the form, proportion, and minor details of construction of the parts as fairly fall within the scope of my invention may be made without departing from the spirit or sacrificing any of the advantages thereof.
Having thus described my invention, what I claim. as new, and desire to secure by Letters Patent, is*
1. A mold of the class described, comprising a plurality of superimposed sections, each consisting of a series of side pieces each having one edge abutting against the inner face of one side piece and its other edge terminating beyond the abutting edge of the other contiguous side piece, an L-shaped binding member secured to the end of each side piece with one arm abutting against the extended portion of the contiguous side piece and having slots provided longitudinally of the arms, means for adjustably securing the contiguous portions of the binding members and interposed side piece together, and means for se curing the abutting ends of the sections against movement.
2. In a mold of the class described, a series of side plates arranged to form a quadrangular body and each having one edge protracted beyond the plate next in order, L-shaped girdle-irons secured at the opposite ends of each plate and having slots provided in each arm and one arm abutting squarely against the protracted end of a contiguous plate, bolts for passing through the slots in the opposing arms of the contiguous girdle-irons and the interposed portion of a plate, whereby the relative position of the plates may be adjusted.
3. A column-mold of the class described, comprising a plurality of superimposed sections, each section consisting of four side plates arranged to form a quadrangular body and each plate having one edge projecting beyond the abutting edge of the succeeding plate, a member mounted at the opposite ends of each plate in the angles formed about the perimeter ofasection and having arms extending in a plane with the contiguous plates in flush position therewith, means for connecting the contiguous portions of said members whereby the interposed plate is retained in proper adjustment, and means for rigidly connecting the contiguous members of the abutting sections.
4. A mold of the class described, comprising a plurality of superimposed sections, each section consisting of four side plates arranged in the form of a quadrangle and each plate having a side edge passing beyond the abutting edge of the succeeding plate, girdle members formed from angle-iron bent longitudinally into I... shape mounted. in inverse positions at the opposite ends of each plate, each of said members being positioned to have one arm bearing against the extended portion of one plate and the other arm bearing against the contiguous plate, means for retaining the contiguous portions of the girdle members and interposed plate in adjusted position, and means for securing the horizontal flanges of the girdle members on the abutting ends of the superimposed sections together.
In testimony whereof I have hereunto signed my name to this specification in the presence of two subscribing witnesses.
- JOHN C. RUSSELL.
