CONCRETE-MOLD HOLDER.

Application filed September 25, 1926. Serial No. 137,712.

This invention relates to a mold for form- 1ng concrete walls, and including opposed mold members constituting the opposite sides of a mold cavity into which concrete 6 may be poured to form a wall, the mold members being capable of adjustment so that they may be located first in position to form the base portion of the wall, and then raised from time to time to form additions to the base portion until a wall of the desired height is formed. v The object of the invention is to provide improved means for confining the mold members in each of the successive positions re uired.

f the accompanying drawings forming a part of this specification,-

Figure -1 is a perspective view of the frame and its adjuncts constituting one of the units of a concrete mold-holder.

Figure 2 is a side View, showing two of the frames assembled with mold members.

Figure 3 is a section on line 33 of Figure 2. I

Figure 4: is a view similar to Figure 8, showing a different adjustment.

Figure '5 is a fragmentary view, showing one of the frame members and one of the mold members inclined, to form a wall decreasing in thickness from its base upward.

Figure 6 is a fragmentary sectional view, showing the base and one of the uprights, adjusted for storage and shipment.

The same reference characters indicate the same parts in all of the figures.

'My improved holder is embodied in a frame and adjuncts thereof, constituting a unit of holding means, adaptedto hold mold members of indeterminate length.

The frame comprises a base which, in this instance, includes a thin body portion 12, preferably a metal plate, and a thicker end portion 13, which may be a block of wood, or other material, secured, as by a bolt or bolts 14 (Figure 6),-to the body portion. The frame comprises also two spaced apart uprights 15 and 16, engaged with the base, a tie member 17, connecting the upper ends of the uprights, a pair of mold confiners, and a pair of mold supports. The confiners are preferably composed of substantially U- shaped slides 18, movableon the uprights, and hooks 19, pivoted to the slides. The mold supports are preferably composed of substantially U-shapedslides 20, bolts 20 inserted in the end portions of. the slides,

and wedge-shaped chocks 21, interposed between the uprights and the bolts.

The hooks 19 are adaptedto engage the upper edges of two'opposed mold members 22, and confine-said members against the uprights at various heights. 21 are adapted to bear on the lower edges of The chocks the mold members 22, and'support the same at various heights. The upright 15 is fixedly secured to the base, preferably by means permitting the relative arrangement of said parts shown by Figure 6, to enable said upright and the base to be stored and transported in compact form, the securing means preferably including a hinge 23, connecting the upright with the base, portion 13, and

a brace .24 attached at one end to the portion 13, and at its opposite end to the upright by a removable bolt or screw 25, so that the brace may be detached from the upright. The upright 16 is detachably secured to the base portion'.12,'preferably by a headed stud 26 and a keyhole slot 27 which may be one of a plurality of alined slots, as shown by Figures 1 and 6. The head of the stud 26 is passed through the larger end of a the slot, and the stud is then moved into the smaller end, so that the stud head is prevented from vertical withdraWalfro-m the slot. The upright 16, therefore, may be detached and stored compactly beside theengage the upper end of theupright 16,

when the latter is inclined, aswell as when it is vertical, the tie member being preferably pivoted at 28 to the upright 15, and provided. with a plurality of notches 29,

either of which is engageable. with a detent 30 on theupper end of the member 16. Said notches and detent, the plurality. of slots 27 in the base, andithe stud 26 adapted to engageeither of said slots enable the up rights to be'variably spaced apart, when the upright 16 is vertical and when it is Y inclined.

The hooks 19 and chocks 21 may be stored at random onthe uprights, as indicated by Figure 1, when the frame is not in use. In preparing the frame for use, the slides 20 base portions 12, and the slides 18 are moved downward, to engage the books with the upper edges ofthe mold members, as shown by Figure 3 A vwall portion V is then formed, by pouring concrete intothe' mold provided by'the foundation and the mold members. W'hen theconcrete is sufiiciently solidified, the mold members are raised and the slide 20 and chocks 21 are applied to the uprights,in positionto support thera-ised 'mo'ld' members, asshow'n by Figure 4, the Wedge-shaped chocks being forced tightly between V the bolts 20 and the uprights, so that the chocksand theslides 20 are firmly clamped on the uprights. A wall portion VV' is then-formed, by pouring concreteinto the mold provided by the portion W and v the moldmemb'ers;

The last described operation may be" rep'eated-uii'tila wa ll of thede'sired height is formed, the length of the uprights being sufiieie'ntto'p'ermit-a suitable number of said operations. After the" wall 'is completed, the upright 16 is detached from'the base and the tieime'mber; and'the' upright 15 and the base are then removed, the thin portion 12 of theba'sebeing readily withdrawable from the shallow recessformed thereby in the base ofthe wall.
