Asbest shown in Fig. 3, a joist supporting member 25,.which is provided with a shaft 26, and a prong 27, may beselectiv ely interchanged with the member 22.

As shown in Fig. 1, the head-plates 22 are adaptedto support the beam box 28 of the forms while the joists are supportedby means of the member 25. I

'A slip-ring 29, as best shown in. Fig. 5," is adapted to be adjustably secured to and. encircle the lower tubular section 18.

. locationof the slip-ring upon the section 18 may be governed by means ofa set screw whichwhen rotated by means of a wrench,

will lock the slip-ring 29 in a selected position upon the tubular section 18. The slip ring 29 is provided with a pair of prongs 31,

these being disposed in planes approximately 90 degrees from each other. They project in directions opposed to each other, one prongbeing'turned upwardly and its mate downwardly for purposes later described. It will be understood thatany required number of shores may be used for supporting. a form, the exact numberbeing governed by the'wei'ght of the concrete. slab while it is in porous condition.

r In operation the planks. 10 heretofore men tioned are placed upon the foundation and 1 for the receptionjof the nails 34 shown'in Fig. ,1.

spaced apart at regular intervals: and pre determineddistances. The adjustable shores are now placed upon the planks 10 with the thinner edge offthe wedge blocks 11 under the foot-plates 12 of each shore. The shores are now spaced apart and placed Vertically 1 by means .of a lateral brace-strip consisting preferablyof apiece of'common- 1 x6 indic ated'at 32. It will be'noted that the 1x6 is placed in'under-the downturned prong 31 of the slip-ring and is secured to said slipring by: means of nails. The 'downturned prong 31 is provided with two nail holes-33 It will be understood that before nailing the 1x6 tothed0wnturned prong 2 31, that the'slip-rings are secured to the tubular sectionsby' means of theset screw s30 so so. v noted that the shoresmay be spaced apart that said set screws will be equidistant from the bottom'of each shore.

By the abovedescribed meansit' will be and readily-locked together at a minimum of .expense, since the nails 31 arebut temporarily. driven into the 1x 6 brace-strips.

* Several rows of the shores are erected in the above.described'manner'after which they I are locked together transversely by means of 1 x 6 brace-strips 35 which member with v Jtheupturned prongs 31of each slip-ring are so i secured by. nails 36.-

I It will be noted that preferablyeacliii'fth shore is provided with-a head-plate 22 at its upper end. -The shores containing the headplates are; now moved upwardly to their approximate altitude andthebolts21 heretothe underneath sideof the ship lap flOOring The intermediate shores are provided with oist retaining heads such as shown in Fig. 3. Said heads are moved upwardly and retained by means of bolts 21 in the same manner asheretofore.- described;' The heads 25 are adapted to butt againstthe underncath side of the ship-lapifio-oring 38. At;

thistime' the joist 41 may be placed. under the ship-lap and se ured to the head-s25 by through the nailphole's. 42' of the heads 25.

If preferred, the oistl may be secured to the heads25 before. the heads 25 are raised. After assembling the form and. its supports asv above described, the operators now secure-a leveling adjustment by means of the wedge blocksll whichare driven one toward the other.. Y

- It will'beunderstood that the wedge blocks 11 operate in pairs. Each wedge block 11 is driven "towards its mate a; suflicient distance to cause the upper endofithe shore and the ship lapping 38 to gain anabsolutelylevel surface which is usually. ascertained by means of tlienails 41 which are passed means of'aspiritlevel and: straight. edge in the handsof a-mechanic. Aftersecuring such adjustment, nails 43 are drivenmthrough the nail: holes 15 of the foot-plate thereby sei curing the foot-plate to the wedge blocks and also looking the wedge blocks together in a removable position If? desired, the

nails 13 may be ClllVGIl'IlOlZIOIllY through the wedge blocks 11 but alsoiinto the foundae tion planksld. 3 j

It is obvious that Ihave provided afsimple economical arrangement of shoreswhioh in use provide a ready means for erecting and. supporting concrete formsin an economicalmanner. 1 f

When not in use and' if it is desirable to store the shores or transport them, the tu- V I 'bul'ar sections 18' and 19 are allowed to remain one completely telescoping with the other. The foot-plates of eachshore may be readily removed from the tubular sections by withdrawing the bolt 17. .Also, the. headplates-22an'd joist members 25 maybe readily takena'part and. placed in. barrels; or other containersfortransportation.

. I claim as my invention J An. adjustable shore, comprising av post section, adjustable strip supporting means mounted on said. post section, afoot plate for supporting the post section and comprising a relatively flat sheet metal body portion of substantially rectangular configuration and having a pair of its oppositely disposed corners upturned for engagement against the opposite sides of the post, a bolt detachably engaging through said upturned corners of the foot plate and through the post for anchoring the latter to the foot plate, the intermediate corners of the foot plate having apertures therethrough adapted to receive nails and the like, and a base section for engagement beneath said foot plate and comprising a pair of oppositely inclined contactl ing members adapted for overlapping engagement to support the foot plate and the post section, said base section adapted to be moved into superposed relation to raise the foot plate and the post section, and said nails in the opening of the foot plate adapted to engage said base section for holding the same when adjusted.

In testimony whereof, I have aflixed my signature.
