This invention relates to apparatus for forming, concrete floor molds, and particularly to temporary supportssor shores on which the moldsare supported. I g It is frequently desirable to construot one portion of a floor of a thicker slab of concrete than another portion where the thickportion i is" required. to carry a heavier load than the other part. The forms for the mold forthe thick slab are assembled in a lower plane than those for, the thin-slab, with a substantially vertical wall between thein the idifierencexin thickness between the two slabs being varied according tothe difierenoe in the; loads to be carried thereon. r l 1 The principal object of this invention is the provision of;a shore which isisiinple in construction, efficient in use, and adapted to support thefloor forms on oneside ata higher. level than those on the other side. f i Another object ofthe, invention is the pro: vision'of a shore ofthis kind adaptedto su port the floor forms on onefside in a higher plane than thoseon-the other side, said shore being adjustable to vary the-verticahdistance' between saidplanes. f I

This construction sometimes interferes with the removal of the floor forms since the forms are: connected to each other. In the present embodiment, these vertical walls can be mounted directly on the shores, and to this end, the flanges 32 and 34 are provided with openings for the reception of bolts, whereby the vertical walls 45may be secured thereto. The shores. 3 are provided with similar flanges 46 to which the walls 45 may also be secured. v The flanges 32, 34 and {i6 arecut away at their upper ends to provide a clearancefor the downwardly projecting marginal flanges on the floor forms, and thewalls i5 overlap said flanges at the top and have outwardly projecting flanges at their ends adapted to illustrated which is convertible so that it may be usedfor supporting floor and beam forms or interchanged with the shores 3 described above for supporting floor forms at'the points where athick slab joins a-thinner one. .The interchangeable shore comprises an upright support 50, mountedon a bracket 51, and hav- V .-ing a bracket 52 secured thereto intermediate its lateral edges andflush with its upper end. A form supporting arm 53 is pivoted to the bracket, and atop 54: is mounted on the upper endsof the'support and bracket and flush with the inner face ofthe support50. The

support 50 is provided'with a'plurality of slots or openings 55 arranged in two vertical lines extending throughout the length of the support on opposite sides of the bracket '52. A'carrier 56 in all respects like the carrier 15 is provided with openings 18 adapted to register with the openings '55 for the reception of bolts, whereby the-carrier may beiadjustably secured to the inner'faceoppositethe bracket i 52 of the support. 3 I r Angular brack ts 57 aresecuredftothe outer 'face of the support 50'flush withj itsvertical side edges and provide the outwardly eXtending flanges" 58, each of which is provided with vertically alined slot's59.
