Application filed April 16, 1925. Serial No. 538,731.
To all whom it may concern:
Be it known that 1, WILLIAM lvnrrrinnn BnNsoN, a citizen of the United States, residing at Chipley, in the county of Harris and State of Georgia, have invented certain new and useful Improvements in a Form for Concrete Construction, of which the following is a specification.
The present invention relates to forms for concrete constructions, and more particularly tothe interior portions of said forms and has for its principal object to provide a structure which will compensate for the contraction of the concrete as the aine sets.
Another specific object of the invention is to provide a joint between parts of a form for concrete constructions which may expand and contract so as to prevent the concrete from cracking as it sets.
A still further object of the invention is to provide a joint of this nature which is exceedingly simple in its construction, efficient and reliable in use, strong, durable, and well adapted to the purpose for which it is designed.
With the above and numerous other ob jects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.
In the drawing Figure 1 is a top plan view of a form embodying the features of my invention.
Figure 2 is a fragmentary inside elevation thereof, and
Figure 8 is a longitudinal section taken on the line 3 3 of Figure 2.
Referring to the drawing in detail, it will be seen that the form with which the present invention is illustrated in the accompanying drawing is substantially square in formation, but the shape thereof may be changed to conform to the desired shape of the concrete being molded, and poured. This form represents the interior portion of a mold, and consists of a plurality of segments 5, one end of each segment is provided with a plate 6 for overlapping the adjacent end of the next segment. Blocks 7 and 8 are fixed on the interior of the segment 5 adj acent their ends. The blocks 7, and the adjacent ends of the segments are provided with registering slots 9. Bolts 10 extend through the plates 6 and through the slots 9 and have oblong buttons 11 rotatable thereon. It is to be noted that the plate is fixed to the end of each section adjacent the block. A bowed leaf spring 12 is fixed at one end to each block 8 and thelintermediate portion thereof is adapted to engage the adjacent block 7 for holding the adjacent ends of two segments normally separated. The bolts 10 will limit the separation possible between the adjacent ends of the section. It is quite obvious that by registering oblong buttons 11 with the slots 9 that the segments 5 may be disassembled, or assembled, as desired.
When the concrete is poured about this form on the outer side thereof and starts to set, said concrete will contract, and there is considerable danger that the concrete will crack. In order to prevent this cracking the springs will flex so that the form may contract with the concrete.
It is thought that the construction, operation, and advantages of the invention will be clearly understood by those skilled in this art without a more detailed description thereof. It is apparent that the present embodiment of the invention has been disclosed in detail merely by way of example, and that numerous changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.
Having thus described my invention, what Iclaim as new is 1. A form of the class described including a plurality of segments, the adjacent ends of said segments having spring means therebetween for normally holding them separated and allowing them to contract toward each other, and means for loosely holding the sections together.
2. A form of the class described including a plurality of sections having their ends disposed adjacent each other, blocks on the adjacent ends of each pair of sections, a plate on one end of each pair of sections for overlapping the end of the other section of the pair, a bolt and slot connection between the last mentioned end and the plate, and a spring disposed between the adjacent ends.
3. A joint for sections of a form for concrete structures including a pair of adjacent ends, blocks on the ends of the form, one of said blocks and the corresponding end being provided With registering slots, a plate extending from the other end and overlapping said slotted end a bolt extending from the plate through the slots a button on the end of the bolt, and a leaf spring of bowed formation having one end fixed to one block, 10 and its intermediate portion bearing against the other block for holding the ends normally spaced.
In testimony whereof I afiix my signature.
WILLIAM WHITFIELD BENSON.
