This e inventionv relates; to and? useful Yiniprovemen in. a forno` 'for l`'concrete `con"- struction.

one Otje@ ofi-the mantiene reprend-e. a form yfor mold speci-ally designedl for Suse inl erecting the walls' o buildings-formed of' plastio'material suoli -as-oon'orete I y Another object of-` the invention is to i proa vide aftype Ofbuildingffbrm by the use of" beerec'ted by a practically'continuous'proc#y ess, ory operation, by elevating tlie"y forms when one section `Vof 'the walls Iliave beeny pouredf and have set", and pouring another seotion,` and so ony untily tlie walls` aregcoin'-,

p'l'et'ed. Theseotions thus superiinposedone upon the other 'are united together and form ay continuous wall' of uniform appearance.

A furtherr feature of the invention jiiesidesf in the provision of a 'type-ol" building-form whereby a ldouble wall maybe erected and tiedto'getlier in suoli a manner tliatlthewalls.

notches

13, 13,'in the upper edge of` each course, as formed.v

The anchoi` plates 3, 4, have upwardly diverging slots v14, 14 and the '

wedges

8, 9 also havev upwardly diverging

slots

15, 15.

l These upper ends of the slots 15 overlap the lower-.f en ds of the corresponding slots 14, when theV Wedges are in Vlower position..

Vhen it is desired to elevate l.the forms, keys as l'are driven through said slots, as illustratedin Figure 2, to force them into regisf tering position. This will elevate the Wedges and release the anchor plates and the entire form maythen be elevated. `The forms are elevatedv until the mold-boards do not quite clear the upper edge ofthe completed section of the wall, and tie rods as 17 are laid Vvtransversely. with their respective ends resting in opp'ositenotches of the completed

wall sections

18, 13, and the molds are then lslightly lowered until thek

inner mold boards

2, 2, rest on said rods, the lower edges of said mold boardshaving

notches

19, 19, to re# -ceive the rods, as indicatedin Figure 1. The molds are 'thus supported while another course of the wall is being poured.

The plastic Vmaterial ofthis additional course is then poured and will run into and harden in the

bottom notches

13, 13, to asf sistin uniting the superimposed sections to-V gether, andthe

rods

17, 17 also tie the outer and inner wallstogether. Itis to be also Vunderstood that vertical reinforcing rods (not shown) will be embedded in each course and the upper ends of these rods will project above said course and be embedded in lthe `course jabovewhen it is poured v,toV tiethe superimposed sections together in the' usual Way.

, When heavy forms are used a derrick may be erected for a block and tackle (not shown) to be used in the usual way for .lifting said forms. The derrick shown consists of the

uprights

20, 20, having the crown block 21 for an obvious purpose'. rights may be provided with the

lugs

22,22, if desired for engagement over the tie rods 17 to support the ,derriclL If light ,formsl are used, a lifting bar may be Vinserted through the bearing slot 23.
