ln '"aiiying ont my invention as applied e oenstzueio'n of :i fiat slab looi', I proeisnppoiiing inlse work members, the

shores being suiiioly spaced apart for lie pioper siippoi'l of lie load, and dividing the mold sinotine ino bays A, C, ete. lie eonsnciion shown in Figures l to 6 inelusive eeeh shore? provided on opposite sides, adjacent 'elle upper end thereof with e .supporting breolet?, elie construction of which will heeinaftei be pointed out. Rows of leilgeis a, c, ete., are detaohably carried on elle bisckets 8, the leclges b for example being eziiiecl by lie brackets on one side of lie news of shores forming the bay B, the ledgers o having` one end carried on @he breclie of the righi', hand shore on the opposice eide and the other end by the ei respondingbracket, on the proper sliore of lie next row of shores, and similarly with tlieledgers a. This will be Clearly sven from inspection of' Figures l and 2. tfted in other woede the foins of ledgers or the respeeziye bays are carried on the brackets on one side of the slioes forming lie bays iespeeliyely. The rows of ledgers are therefone independent of one another.

Extending longitudinally of the bays and eeiiie, by their iespective rows of ledgers,

accordance with the facilities sveiiable for handling the same. shown the units as comprisingr eight'panels with stringere of the necessary length. it will be understood that more than one unit may he utilized in n. bey, this being made possible, for example, by overlnppinvr the ends of adjacent sets of stringere es siown in Figure. l, but `ot sew-ing the end panel which will be supporter?. by the stringers of either unit While the other unit is being taken down.

The gaps between the sides of adjacent units are closed by stretchers or filler pieces il. preferably in the forni of sheet metal plates, the ends of which overlap the ends of the panels of adjacent units. The stretcheis are supported et inter vvals intermediate tlf units by the supporting or Stringer mem- 12 carried on the tops of the shores 7. lcierring now to Figures i and 5 to 7 inel e it will be seen that the pair of brackets carried by each shore Y are npertured to receive common holding bolts i3 passing' through bolt holes in the shores. Washers is: are provided under the heads of the bolts i3 and their respective nuts to permit the brackets to be readily turned about the bolts as en axis of rotation. The. jew portions of the brackets serve to tightly clamp and the ledger members against the shoringg when the brackets ere rotated to Vertical position. by reason of the engagement of the lower end of the brackets with the Wedge members l5. which are preferably secured` to 'the shores by such ineens es the screws i8. The lower ends of the brackets nre provided with inclined surfaces coopersting with the Wedge members to drive the lower ends of the brackets outwardly from the shores which in turn'iinpnrts en inward movement to the upper ends of the shores, as will be clearvfroni inspection of Figure 7. The brackets 8 are heid in ledger clamping position by temporary Ineens such es the nails 17. It i'iili be seen from the construction just described thi/it Whenever it is de sired to remove one or eil oi the ledgers for s. unit. this muy be resdiiy accomplished by taking out the nails 'i7 and swinging the brackets to the position shown5 for example in Figure 3.

Vith the parts assembled in the position shown in Figures l and 2, (preferably with units set up for :in entire door :it once), vthe concrete is poured. After it has set. s comparatively short period of time, the incid units may be teiten down, the concrete being suiiicientl)r supported by the stretchers il and stringere 12- which are left in position. The manner ot' taking down the units will now be described Assuming that the unit or units of hay .s have been taken down, and the unit or Aunits of hay B are to be teken down, pairC or" ifa-ee,

ll'n Figure l, I here.

'porziry ledger members ure elevated take-down members such as the extension ladders 19 are set up, the upper ends of which are rested against the stringcrs i2 :it one side of the hay and against the stringers 9 et the other side of the bay. Each ladder is provided with a cable il() passing oiler e. pulley 2l und the pairs of ladders are arranged in opposition so that the ends oi' the cables may be secured to n pair of 'ten'iporary ledger inenihers These teinund brought into position bene-nth the stringere'l 9b. occupying n position such :is indicated in dotted lines in Figure i, The brackets holding the ledgers are loosened and turned to the posi-tion indicates in Figure fi which permits the removal oiC the ledgers 7). and the mold unit nonv rests solely upon the pair ot temporary ledgers The unit muy non' be lowered by easing' oii on the cables und the loweriiifbr .may be continued until the temporary ledgers rest upon the tground. eficiwhich the unit muy be picked up und. transferred to n new point tor sel ting up. or the unit um): he lowered onto :i truck such as is dingrnnin'miculij.' indicated in dotted lines in Figure i ut D und shiitcd to it new point ot' use. it will also he seen thato the units muy be assembled on the ground und elevated initially in a wry ne simple manner und that unit when teiten down muy be Jinvited und supported :it n new poni?r of if. the ledgers placed/in position und cinn'iped. The Work may be therefore carried out expeditiously, economically 3Go und progressively.' with e n'iinin'iuin amount of equipment.

Referring now to Figures S, 9 and i0, i have therein shown n modification of the brackets for 'supporting the ledgers. The brackets in this cese are provided with slots 9.3, adapted to receive the Wedges :2li which when driven home tightly serve to spread the lower ends of the brackets sway from the shoring, forcing the upper endsthereof toward the shoring to clamp the Aedgcrs.

in Figure 1.1 have shown n modified erriingeinent oit fiiler or siretcher member ii which is adapted to lie flush With the top surfaces of the. panels l0. The stretcher mehr bers in this case :ire supported as before.

.instead of einpioying separate brackets for supporting the respective ledgers I may use n head -for the shoring., such head coinpris'lng s pair ot srnis or cross pieces 25, each pivoted its inner end to the shorel by ineens ot' s. boit 26. The arins or cross pieces are supported by foldahle braces 2T, each con'lprisino s pair of members pivoted together es at. 2S, the end ot' one member being pivoted to the end of a cross piece by s bolt 29 and the ends ot the oth r members being; pivoted to the shore by :1 common pivot bolt 30. The braces src provided with iock pins 3l which permit the braces to' be colinpsed the shore. 't0 top thereof, on opposite faces, e pair of en- 30 ,gether by :t single iu?- 59 bracket may be hung fr incensi Il pieces. ln dropping the respective units the cross piece is lowered by collapsing the brace arm is indicated, the operation in other respects being the same as that described.

' ln .Figures 13 and ltinsteed of providing .e two part folding head, the head oi the shore consists oi two brackets 82 and 33, adapted to be inserted between the flanges 36 ot two straps or yolre members 3? adapt l ed to embrace the shore es shown in Fig-l lure 11i. The brackets and the flanges are "'.spertured and Wedges are driven into the npertures securely fastening the brackets to Esch bracket hss secured to the gives' 39 to torni a seat for the stringere, which in this instance ere Wooden. ln taking` down e. unit, the proper bre-.cirets are removed by knocking out the wedges 38 after which the operation is es before described.

Referring now to .Figures 15 to i? it will be seen that ll have illustrated e modified form of bracket consisting' of e pair or side plates l5 heving hooks lo and secured toslieped strap s?, the base of which -f nds above the top edges of the plates. "l ie brackets are hooked over e bolt 48 with which each .shore is provided and they ere held in ledger supporting position by ineens of keys or wedges 49 in the manner h ereinbefore ser. forth.

Esch bracket is provided et the top with a transverse plate or bei' 50 which not only strengthens the bracket but serves es u sent l :lo for the ledger.

This i 'fr plete is so located with reference to e center of 'the hooks that when e brsclret swung 90S to the position shown in Figure 1'?, the ber will engage the side of the shore and siipe5 port the bracket with the strep 4J? estend- .ing et right angles to the shore. The projecting portion 0:5 the strep 'will then serve tosupport a ledger.

lt will be observed shore which maires it when the door units reed enough to cover more then one bey with ledgers of suitable length, or in any other errengeinent in which it unnecessary to provide sill the lshores with more than one bracket. l. ein thus enabled to cut down the number of brackets required :tor permanent slant.

By mali-.ing the brackets slightly Wider than the posts, and by using bolts et. suiib cient length, l ein enabled 'to support s. pair of brackets from each, bolt.

@ne of the importent sdventeges ci? my im Jrovements `is that standard lengths 'ott S5 stringere end ledgers mcy be need end cub -also eliminated.
