Y It is to be The mold 10 developed by use of the various expected that there will be some variation in 105 boards 11, 12, 13, 14, and 15, is built up in any different buildings in the distances at which the of the manners or methods common in this art. beams are disposed, wherefore the soii'its 23 and The boards 11 and 15 are generally called battens the means associated therewith are adapted to and extend transversely of mold boards 12 and be adjusted to the indicated variations. For 14, at intervals along said boards 12 and 14. It accomplishing this purpose the soits comprise 11u soits.

a table member 230 carrying a depending vertical brace 24 that may be secured to the sofiit by suitable nails or bolts. Brackets 25 may be used to support the table 230 on the brace 24. At the ends of a soiiit table and a brace it is desirable to provide a slot or recess indicated at 26 in Fig. 3. This slot or recess may be effected in any suitable manner, for example, as shown herein by spacing the table member from the upper edge of the brace 24 by inserting suitable shims 231 between the table 230 and leg or brace 24. An inverted U-shaped sheet metal extension 27 is adapted to have the base 28 thereof projected into the recess 26. The extension may be provided with elongated slots 29 in the depending legs 30 thereof, said slots adapted to vreceive a bolt and wing nut structure 31 carried by the brace 24 for clamping the extension at Various degrees of projection in or out of the recess 26. A pin 131 may be carried by the brace 24 and serves to preclude sagging of the extension and soiiit. The outer end of the extension, or in other words that portion of the extension projecting from and beyond the recess 26 is provided with a pair of lateral flanges 32 and 33 that are formed by bending the legs ,30 at approximately right angles. The base portion of the extension comprises a lap, finger or arm 34 having its lateral edges 35 severed from connection with the iianges 32 and 33. An angle plate 36 that may be of sheet metal, has its longer leg 37 in abutment upon the flanges 32 and 33. The shorter arm 38 of the angle plate 36 lies below and in abutment upon the arm 34 formed upon the base 28 of the extension. The angle plate may be permanently attached to the extension by means of rivets or other suitable means. The shorter arm or leg 38 of the angle plate rests upon a support or ribbon board 18. If desired the L-shaped plate 35 may be dispensed with. A like extension structure may be provided at the other end of the soit. The thickness of the various members used for mounting the soft upon the support or ribbon board 13 is such that the soft when mounted has its upper face flush or in substantially the same plane with the face 22 of the edging strip 21. In order to close the space between the end of the soiiit and the mold 1G, see Fig. 1, there are provided angle brackets 39 comprising a pair of parallel plate like members 40 and 41 integral with and connected by an in termediate webbing or plate like member 42 extending substantially perpendicular between said members 40 and 41. The members may be provided with suitable apertures 43 through which Y fastening means such as nails may be driven for securing the angle plates upon the soits at the ends thereof for bridging the space between the soffits and the mold l0. Between the angle brackets 39 supported on adjacent somts, see Fig. 2, there are inserted filler strips 44 of a thickness substantially identical with the thickness of the table portion 230 whereby a framework results to preclude the escape of wet or mush concrete adjacent the mold 10 and between adjacent The soiiits are adapted to receive suitable metal tiles, forms or members indicated in dotted lines at 45 in Fig. 2. The use of metal tiles in this type of construction is well known and is ancillary to the invention disclosed herein. From the foregoing it should be evident that the softs may all be mounted in position without the provision of any supporting structure in the nature of shores. In other words the soits are all supported from the mold 10. Thereafter suitable cross braces 46 may be attached to the brace 24 and suitable snoring 47 may be positioned beneath the cross braces 46 for taking up the weight and load of the concrete when poured over and upon the sonits. When using the temporary structure disclosed herein the shoring 47 supports practically no weight or load until the concrete is poured into the mold or form, wherefore it follows that the shoring may be expeditiously mounted beneath the softs. By reference to Fig. 5 it is evident that the cross braces or stringere 46 may be held in position below the brace 24 by means of collar 48 comprising angle irons 430 and 481 receiving the brace or Stringer 24 between the vertical arms 49 and 490 thereof and to the base of which are attached suitable angle irons 50 and 501 for providing between them a way into which the brace member or Stringer 46 may be received. A perspective view of this structure is shown in Fig. 8. Suitable fastening means such as nails may be used to attach the members43, 24, and 46, to one another. If desired a vsuitable block 51 may be nailed upon the shoring 47 and the cross support 46, although in practice it has been found unnecessary to provide a block 51. In building up the joist molds, the collar members 43 may be fastened to the brace 24 of the soiiit. Thereupon the stringers may be attached to the collar members, and then the snoring may be placed below and in conact with the stringers. of construction and assembly effects rapid construction of the joist mold.

On some occasions it may be desired to provide cross bridging intermediate the soffits as shown in Fig. 6. At such places, a filler strip such as 44, carrying angle brackets at its end would be inserted between and supported from adjacent somts, the tiles or pans being capped at such places, wherefore a cross joist of concrete would be molded at such place.

In some installations, the soits may be supported at an end by means other than a beam mold such as 10. For example, the concrete joists may terminate at one end upon a brick wall as disclosed in Fig. 7. Under such circumstances the ends of the soflits would be supported in substantially the manner shown herein, however, the ribbon board 18 would be supported by a structure other than a beam mold, for example shoring and stringere that would be built up along a wall at which the joists would terminate. In View of the disclosures herein, the suggested structure becomes readily obvious to those skilled in the art. In some instances the sharing or support means other than a beam mold, brick wall, or ribbon board may be provided for establishing the means upon which the extensible ends of the sofits may rest.

Although the soits shown herein comprise a table 230 and brace 24, it is readily evident that the table portion of the somt may be dispensed with, and that the body or brace portion may constitute the soilit proper and may carry suitable eXtensible means or parts that function as do the extensions 27. Accordingly the sortit member that may be employed may be properly soffits and contacting the supports at opposite' ends of said soints for aligning the upper faces ofthe soiits with the upper edges of the molds,
