CONCRETE-MOLD.
Specification of Letters Patent.
Patented Dec. 28, 1929.
Application filed May 20, 1920. Serial No. 382,865.
To all whom it may concern:
Be it known that I, HARRY K. CARPENTER, a citizen of the United States residing at Clarksburg, in the county of flarrison and State of West Virginia, have invented certain new and useful Improvements in Concrete-Molds, of which the following is a specification.
My invention relates to forms or molds or concrete construction and more specifically to devices of this character which are adapted for the construction of concrete floors and the supporting beams associated therewith.
Tts objects are to provide a device of this character which will be cheap to manufacture, light in weight, simple in operation, and free from troublesome bolts, clamps, and complicated interlocking means.
A further object is to provide a device of this character which will reduce the cost of concrete construction by diminishing the time and labor required. This is accomplished by the ease and rapidity with which the invention may be erected, adjusted, and removed.
Another object is to provide a device of the character described which may be conveniently adjusted to permit the construction of beams of a variety of depths. Uther objects of the invention will become apparent upon a more complete disclosure thereof.
For a better understanding of my invention reference is bad to the accompanying drawings in which similar letters indicate corresponding parts throughout the several views in which-- Figure l is a transverse sectional view of one unit; Fig. 2 is a transverse sectional View of a portion of concrete floor illustrating the use of a series of units and the method of temporarily supporting the same for the placing of the concrete; and Fig. 3 is a similar view illustrating the employment of the adjustable feature.
Referring now to the figures of the drawings, A represents an elongated metallic form adapted to support a floor-slab and to provide a mold for one side of each of two beams. This member is also denoted bythe subsequent references to floor-slab support. The letter B indicates an elongated metallic form which corresponds in length to A and is adapted to complete a beam mold by connecting one of the depending sides of a floor-slab support A to the adjacent depending side of another floor-slab support. This member is also denoted by the subsequent references to beam support. The letter C indicates a collapsible brace adapted to support the plate a of the floor-slab support A and to support and control the movement of the depending flexible sides I) and b of the said support A The letter D indicates a movable brace adapted to support the upturned flexible sides 03 and d of the beam supporting form B. This brace, which is retained within the finished concrete beam, is of a shape which permits it to support the reinforcing rods F, illustrated in Figs. 2 and 3, which are employed in the construction of the beams. The sides I) and Z) of the form A are provided with the longitudinally extending corrugations or grooves z and 2" respectively. The lower edges of the sides I; and b are formed into the longitudinally extending channels j and 7" respectively. The sides (Z and d of the form B are provided with the longitudinally extending corrugations or grooves in and la respectively and terminate, at their upper edge, in the longitudinally extending rolled edges Z and Z respectively. The grooves z' and i are equally spaced with respect to one another and the spacing of the rolled edges Z and Z and the grooves 70 and la respectively correspond to the spacing of the grooves 2' and i. The rolled edge Z and the grooves 70 are adapted to engage the grooves z" and the rolled edge Z" and the grooves 76' are adapted to engage the grooves 2'. The brace C consists of the hinged arm 9 and the pivoted arms 6 and e. The arm 9 is attached at one end to the arm e and at the other end to the arm 6' while the arms e and e are pivoted at their upper ends to the plate f which bears upon the under side of a and prevents sagging of same under the weight of the concrete. The letters m and m indicate the rounded lower ends of the arms 6 and e which are confined within the channels 7' and j respectively when the form is in use. When the forms are not in use, the braces are removed to facilitate transportation and storage. The hinged arm 9 is movable upwardly but is limited in its downward movement by the flange h arm 9 will impart an upward movement to the arms a and 0 resulting in an outward movement of the sides cl. and d respectively causing the rolled edge Z and the corrugations l0 and the rolled edge Z and the corrugations in to enter the corrugations z" and 71 respectively. The operation of the brace C is clearly shown in F ig. 1. Obviously, the corrugations in the sides I) and b are concave when the corrugations in the sides at and (Z are convex and vice versa.
The operation of my invention is as follows:
.Suitable temporary supports are erected of timber as shown at E in Figs. 2 and 3 upon which are placed the required number of forms 13 in their relative positions. The desired number of braces D are placed within the beam supporting forms B either before or after the same have been placed upon the support E and the required number of A forms, equipped with a suitable number of collapsible braces C, are then placed in position-one A form between each two 13 forms. The arms {7 of the braces C are then lowered eitecting the engagement of the corrugations in the sides of the A forms with the corrugations in the adjacent sides of the B forms and resulting in a rigid whole well adapted for the purposes intended. Figs. 1 and 2 illustrate the relative positions of the forms A and B when the depth of the beams are to correspond to the depth of the sides of the form A. However, the beam depth can be readily increased by lowering the B forms with respect to the A forms and can also be decreased by raising the 13 forms.
with respect to the A forms. Fig. 3 illustrates the latter condition and shows the manner of supporting the beam molds by the addition of the blocks G tothe temporary support E. sides of the A forms and the rolled edges of and corrugations in the sides of the B forms are so spaced that a variety of beam depths may be secured by the use of one set of forms. The forms may be either of a length to meet the requirements of a particular type of building or may be extensible to accommodate beams of a variety of spans. In the latter case, the meeting edges of the forms may be secured together in any suit able manner.
Having thus described my invention, the
