MOLD FOR FOUNDATION PIERS Filed July 31, 1946 2 Sheets-Sheet 2 I INVENTORQ GEORGE W. MC DEARMON,
A'I'I'D RNEYS Patented July 11, 1950 This invention appertains to a mold for making concrete articles, tructural elements, or the like,, such as foundation piers for buildings erected without basements or cellars, and it has for an object to provide one that is comparatively inexpensive to manufacture, simple in design and construction, and quick and easy to as- :semble, fil1,;and remove; the filling with a, suit- Zableconcrete mixture being accomplishedwith .the moldin an upright osition and its removal .fromthe,r nolded elementby. inverting it from u,such position. w
Another; object of the invention has todo with ;the provision of a mold as above characterized, ;,w ith:c ore inserts toform panels, in the nature erdepressions of a, desired .design, in thesides yof a finished foundation pier,-to, lend attractive- :ines theret to e fect a t on in tsi s and likewise in the amount of the concrete mixture necessary forits production; the body of the mold automatically separating from the core f ainserts duningits removal from the finishedpier.
With the foregoing and other objects and advantages of an equal importance in view, the invention resides in the certain new and useful combination, construction, and arrangement of parts, as will be hereinafter more fully described. set forth in the appended claim, and illustrated in the accompanying drawings, wherein:
Figure 1 is a side elevation of the mold, in accordance with the invention and as it appears in upright position for filling with the concrete mixture;
Figure 2 is a vertical section, showing certain of the core inserts positioned within the mold body and detachably connected thereto;
Figure 3 is a top plan view of the mold when inverted, from its position as in Figures 1 and 2, for its removal from a finished pier;
Figure 4 is a horizontal section, taken through the line 4-4 on Figure 2, looking in the direction of the arrows;
Figure 5 is a perspective view of a finished foundation pier Figure 6 is a sectional view similar to that of Figure 2, but showing the mold inverted for its removal from a finished pier and the means and manner for effecting its removal;
Figure '7 is a fragmentary vertical section through the bottom end portion of the mold body and showing the manner in which an anchor bolt may be affixed in the top end of a pier during the molding operation; and,
Figure 8 is a fragment of a side wall of the mold body, showing the manner of securing one I of the cleats on its inner side for cooperation ,with a companioncleat secured on the outer sideof a core insert.
Referring to the drawings in detail, the foundation pier to be produced in the use of the mold :is illustrated in Figure 5 and is comprised in a flared base portion A and a body portion 13 rising centrally from the base portion and having the form of a frus-tum of a pyramid; the four sides of the body portion B each having .a centered depressed area, constituting an inset panel C.
The mold, as it is exemplified in the drawings, of hollow construction, being made from steel plate to form a flared open top portion In, preferably rectangular in plane, and a tapered'body portion l2, also in the form of a frustum of a pyramid, having its bottom end closed by a square plate |4, welded thereto, with its side edges projecting beyond the end edges of the body portion and an opening I6 in its center, the
purpose of which opening will presently be explained.
In order to form the depressions or panels C in the foundation pier, a core insert l 8, of pressed metal plate, is attached to the inner side of each of the side walls of the body portion [2 of the mold, by being provided with a cleat 20, of spring metal, secured, as by welding, on the outer side of its depressed wall, to engage with a, like cleat 22, secured in a like manner on the opposed side wall of the body portion, the interengagement of the cleats acting to retain a core insert firmly against the body wall, during the filling of the mold with the concrete mixture and the setting thereof.
In putting the mold to use, it is placed in an upright position, with the flared portion l0 uppermost, for the introduction of the concrete mixture, before doing so, however, a brickbat or hardened block of concrete (not shown) is placed within the mold to cover the opening IS, in the end plate M, to prevent leakage of the concrete mixture therethrough. When filled, the concrete mixture is leveled across the open top of the fiared portion I0, and the mold allowed to remain in place until the concrete is set.
After the concrete has set, to remove the mold from the formed foundation pier, it is up-ended, i. e., inverted, and a screw-press is employed to enforce separation between the same; the screwpress being in the form of a rectangular yoke 24, having hooked ends 26 to engage beneath opposite edges of the end plate l4, and a vertical shaft 28 screw-threaded through an enlarged central portion 30, of the yoke, for turning movements to cause its lower end to enter the opening 16, in the end plate I4, and forcibly contact the top end of the pier; a handle 32 being provided at the upper end of the shaft for its manipulation. With the upper movement of the mold relatively to the pier, the cleats 22 disengage from the cleats 20 and the core inserts 18 remain in place in the side walls of the body portion B of the pier and are to be readily dislodged following complete separation of the mold therefrom, as by being pried loose, or struck a sharp blow, with a suitable instrumentality.
As shown in Figure '7, an anchor bolt 31 may have an end embedded in the top end of the foundation pier while it is being molded and, to such end, the free end of the bolt will-be projected downwardly through the centralopening IS, in the end plate I4 of the mold,'a'nd, for instance, into the ground for the support ofthe bolt in the required vertical -position, while the headed end, within themo1d, 'ispro'vided-with an anchor plate 34, welded to'the head 36. Thus, when the concrete is'se't and 'the'finished pier is separated from the mold and lip-ended, the
in its'broader aspects.
-What Iclaim is: A mold for making articles 'of concrete and the like, comprising anelongated hollow metal'body having one of its ends open-and of a flared formation, and a closure plate-welded-across the 'opposite end of said body, said body being substantially square in cross-section-and"tapering from its open flared end to its closed end and adapted "inserts and cleats carried "by the inner side of each wall to coact with the cleats on the inserts whereby said core insert may be automatically detached-from said side walls during the movement of. the separation of said body from said article, and'an opening in said closure plate to permit the passage of an anchor bolt therethrough to be secured in said article when the concrete has fully set.
