Application October 16, 1947, Serial No. 780,274

(Cl. .Z-131) 2 Claims. l

This invention relates to molds by which cornices of cementitious material may be shaped, preferably integral with building walls of like material.

The present application is .a division of a parent application filed by me December 5, 1942, Serial N-o. 467,971, disclosing Molding apparatus for forming buildings, which has since matured in Patent No. 2,434,708 on Jan. 20, 1948.

The principal object of the invention is to provide molding apparatus for the cornices which may be economically manufactured, preferably of sheet metal, a selection made of available units, according to the design of the building, to assemble the form for the pouring of cementitious material, witho-ut the delay and expense of cutting and fitting many special form pieces.

`-Tl'le invention contemplates reuse of the apparatus units in the finishing of the upper portions of Walls of buildings of the same or different design, the units being practically indestructible and requiring little, if any cutting or boring of holes to meet `the `requirements of different building designs.

Another object is to provide molds which are particularly well adapted for use with wall molding apparatus of the character disclosed in the aforesaid parent application.

Other objects and advantages of the invention will appear in the following detailed description, taken in connection with the accompanying drawing, forming a part of this specification, and in which drawing:

Fig. 1, is a fragmentary View in elevation of wall and cornice forms for use in forming a, one story building.

Fig. 2, is an enlarged sectional view on substantially the line 2-2 of Fig. 1.

Figs. 3, 4 and 5, are detail view-s in side elevation of parts of the cornice form.

Fig. 6 is a fragmentary view in front elevation of assembled parts of the cornice form, portions being shown in vertical section to disclose details.

Fig. 7 is a fragmentary View in perspective of parts of a suitable wall form well adapted for use with the cornice form.

The invention preferably contemplates the use of a cornice mold 84 with a wall outer face form, comprising flanged mold `panels |35 and upright channel members |3| of the character disclosed in the aforesaid parent application. The panels |35 comprise a plate-like main body portion |36 provided with lateral flanges |31, and a top flange |38. For a purpose Ito be subsequently set forth, the flanges |31 are provided with longitudinally extending slots |45 andthe ange |38, with transverse holes |46. The channel member |3| comprises a web |33 and flanges |32 relatively deeper than the flanges |31 of the panels |3|. The flanges |31 are each provided with a first series of transverse holes |44 adjacent web |33 for alignment with the slots |45 of panels |35 and a second series of transverse holes |64 adjacent the free edge of the flange, the function of which will be subsequently set forth. Each channel member |3| also preferably has its flanges |32 beveled, as at |51, to facilitate dismembering the mold as hereinafter described.` Suitable bolts |40 are used, accommodated in the holes |44 of the channel member |3| and the slots |45 of the Ipanels |35 for securing these form parts togetherwith faces of the web |33 and panel -bodies |36 in alignment.

The cornice mold 84 is -used to -provide a cornice integral with the Wall. The finish to be given to the wall inwardly of the cornice depends on the type Iof roof construction that will be used to complete the building. In Fig. 2 there is shown a finish suitable for a gable roof, there being shown a gutter 13 formed in the cornice.

The cornice mold comprises a plurality of elongate, horizontally disposed sections 243, each comprising a cornice mold panel 244, shaped to the desired contour of the cornice; a wall forming drop 245 at the lower longitudinal margin of the panel, coextensive therewith; an outstanding horizontal flange 246 at the lower margin of the drop and coextensive therewith, this flange being of a depth substantially equal to the upper ilange |38 of the wall panel |35 and :to rest thereupon when the c-ornce Vmold is in assembled relation on the cuter wall face form; at least one bracket 241 detachably secured as by means 248 to the channel members |3| ofthe wall forms and bearing against the outer face of the panel 244 inter# mediate its ends; and van outstanding vertical ilange 249 at each end of and rigidly secured to the panel 244 for abutting relation with the adiacent flange of the next section 243. Means 250 `is provided for detachably securing the outstanding flanges 249 of adjacent mold panels together, and means 25| is provided for deta-chably securing the outstanding horizontal anges 2416 to the upper -outwardly extending flanges |38 of adjacent wall panels |35.

To facilitate manufacture of the mold panel 244, it may comprise a major portion 252 made of sheet met-al rolled or otherwise shaped to the desired contour and having an outstanding upper strengthening flange 253. The wall forming drop 245 may be the web yof a channel section lof which the lower flange is that designated 24E and the upper flange 254 welded to the under side of the mold panel 244, serving to strengthen the latter. The flange 246 is Iprovided with transverse holes 255 for the reception 'of bolts 25B forming a part of means 25|.

The bracket 24T shown in side elevation in Fig. 4 may be a flat piece of material having an inner and upper margin 2.51 Lto conform to the outer contour of the mold panel '2434, an upright rear margin '258 to abut against the flanges 246 and 254, an inner lower beveled face 259 to conform with the bevel |57 at the upper end of the channel member |3I, shown in Fig. '7, and the remaining marginal portions Zitti 4and 26| may take any suitable shapasucha's atfright angle to each other. Suitable transverse holes 262 may be provided near the lower portion of the bracket for the reception of bolts 263 form -ing 'a part `of means 248. This means 248 may comprise, fin addition to bolts 2,63, a plate 25d provided `with upper transverse holes 1265 for the fbolts, .and rear transverse holes 266 for the resuepti'on :of bolts ,2E-1 :to 4secure Vthe ,plate 2555 to the .channel member.. The bolts '.261 may 'also xbe A'received iin selected holes |64 of the second series .in the ,flange of 5the fchannel section |3| 'previously describ ed.

kThe foutstanding vertical :a-loges 1,249 may Aeach be cut or stamped from sheet meta-l of the pattern shown in .'Fig. 3 vw'llere the inner margin 12,58 conforms tothe inner contour of the mold panel, :the rear lower margin .2.67 `to the web 245 andfthe llower margin :2-0 to 'the flange 24S. The .front margin y2F|f| :may :take any suitable shape. Transverse ,holes 212 are provided for the reception of bolts 213 forming a part of means 253.

F.[lhe .construction and assembly of the cornice mold makes possible the stocking .of sufficient quantities `of sections y244 -of different lengths, .and a selection therefrom to meet particular buildin-g specifications, and the brackets 2M not fbeing secured .to kthe ,mold panel may be placed wherever channel Vmembers 13| may occur in a particular assembly, yto properly support the .cornice mold I.pa-r-iels.

Before :the concrete |52 has set, .anchor bolts .1346, vmay be 'inserted in `.the wall for `ceiling joists 3H and plates y3|-8 for l,any suitable roof conl struction not Yshown in the dra-wings.

When ythe cementitious material 62 has set and it is desired to dismember the form, the :pa-nels 4.35 fbeneath ,the cornice mold may first lbe removed. rIhis may be followed by the re maval `ci' the bolts ,257 hold-ing the plates 25.@ .to the fchannel members =|3| and 4because of the rlower beveled :faces `.259 of 'these plates, engaging the beveled upper portions :|251 ,of the .channel members, :the .cornice form may be eased away :from vcontact with the molded cornice, by the ,plates .2.41 sliding ,downwardly and outwardly on lthe beveled `portions .|.51of the .channel members.

111e cornice mold, .along .one wall ,of the .building may be removed as a unit, or the ,panels 244 may 'be removed, one at a time, by rst removing prising a plurality of spaced, elongated, vertically disposed form members each comprising a web, one face of which forms a -part of the cementitious wall material engaging surface, 'and an outstanding vertical flange, the upper end of which has a beveled surface extending outwardly and downwardly from the plane of the web, and wall form panels detachably connected to and extending between said vertically disposed members, -fone face 4of each of which cooperates with said Webs to form a part of the cementitious wall material engaging surface; and a cornice mold comprising an elongated, horizontally disposed section, shaped to the desired contour of the cornice, disposed above and 'contiguous with the upper margins of said form, a vertical plate Iat each of said flanges, bearing against the outer face of its adjacent cornice mold panel, for the support thereof, disposed to lie in the plane of its respective flange and provided 'with a 'beveled margin 'engaging upon `he said beveled surface 'of 'its `:respective iflange, :and
