I propose to provide an improved molding apparatus including a base mold, wall forms used for exterior walls and inside partitions,
insulating material for obtainin a dead air space in the exterior walls, an forms for ceiling cornices and ceiling slabs.
The'forms incl de a series of panels of relatively small weight in comparison to area, whlch are reenforced by a pluralit of v detachable stifi'ening members, which,mem- 1 bers may be spaced to the different requirements so as to impart suflicient rigidity to the form s to withstandthe pressure exerted against them when the concrete is being poured into the mold. The panels are locked together by simpleand eflective means operatmg to retain them in a flush and aligned relation, and providing for expeditious assem bling of the forms when settingthem up or The panels made in accordance with the features of my invention are of such a construction that they may be easilyand cheap- 'ly assembled. Then,- too, the panels are 'z5-.,properly shaped and are reenforced to keep their molding surfaces flat and unwarped;
I In accordance with other features of my invention, there is provided a novel base 1 mold construction adapted to be associated with the wall panels. Means is provided for locking the base mold to the wall panels in 1 such a manner as to maintain the lower ends of the wall panels in proper alignment. The
basemold is so constructed that after the concrete has been poured and set, it may be with facilityremoved from the molding structure, allowing the bottom of the wall panels to be swun away from the finished 7 concrete walls. Tliat is to say, to is first removed in order to permit access the base mold Application filed April 9, 1926. Serial mi. 106,817.
with facility to the ,wall panels. After the removal of the base mold the wall panels may be lowered from a normal-position and thereafter removed from the walls.
. The invention also rovidesfor locking means between the ceiling panels and the wall panels, whereby removal of the wall anels aftgr the hardening of the concrete s greatly facilitated. without, at the same panels.
.time, necessitating the removal of the ceiling The wall forms of my invention are preferably held together at top and bottomby steel bands passing under the base at the bottom and between the panels and cornice molds at the top.

Referring now to the drawings in detail, in which like reference numerals designate similar parts throughout the several views, I have illustrated somewhat fragmentarily in Figure 1 a molding construction embodying the features of my invention positioned upon a preyiously molded story. As was previously mentioned, my'invention relates to the art of molding one story upon another in building structures. Now, first, I shall describe in detail the base molds of my construction designated generally by the reference character 10, and best illustrated in Figs. 3, 4, 5 and 7. The base molds E10 are preferably positioned upon a concrete-slab or the'ceiling slabs of the under story. This will be obvious from the illustration in Figure l.
The base mold comprises essentially a pluralityof interchangeable units, which units are interconnected by mechanism embodyin features of my invention. Each base mol unit comprises a vertical wall 11 and an angular steel member 12. The wall 11 isprovided with a molding surface 13 against which the concrete is set. The wall member 11 and the angular member 12 may, if it is so desired, be formed integral. I preferably make the wall member of wood and the angus lar member 12 of steel and thereafter connect them by suitable fastening means. The member 12 comfprises a shoe portion l'having a laterally 0 set portion 15 extending substantially vertically therefrom. The angular member 12 also has a leg 16 which abuts the rear face of the molding wall 11. The leg 16 is-fastened to the wall 11. The upper part of the wall 11 is provided with an inclined surface 17 which co-operates withan edge 18 of the leg 16 to form a,sea.t for a wall panel adapted to be superimposed thereon. The inclined surface 1 extends upwardly until it meets the I edge 18 ofthe leg 16 associated with the rear face of themember 11.
w-other end of theunit is provided with a pair of guide pins 23, preferably secured to the leg 16 of the member12 (Fig. 5). These pins 23 extend'from the rear surface of the unitilO and are adapted to fit in apertures 24 in the extension plate 20 (Fig. 4). I desire it understood that although I have illustrated the units 10 in Fig. 3 as being at rightangles with respect to each otherit is, of course, ob-
viousthat the units may be positioned in alignment with the pins 23 of the end of one unit positioned within theaperture's 24- of the plate associated with the end of the abutting unit. Thus it'will be seen that the units may be interconnected in an aligned position.
In Fig. 3 I have illustrated the units 10 as being connected to a corner base member, designated generally by the reference character 25. This member 25 comprises an angular cast iron member 26 adapted to be aligned with the walls 11 of the adjacent units 10. That is to say, the outer faces of the member 25 are adapted tobe aligned with the molding faces of the units 10to present a perfectly flush outer molding surface to the concretebeing poured. a
Secured to the-angular member 26 by a bolt 27 is a plate 28 (Fig. 5) having a pair of apertures 29 for receiving the. pins 23 ofthe associated end of the mold member 10.. The plate 28 is equipped with an aperture 30 through which the shank of a screw 31 is threaded into the member 26. The screw 31 may be removed to permit of the mbving of the plate 28 to the position illustrated'in dotted lines in Figure '5. The plate 28 is equipped with a slot oropening 34 having a reduced portion 35.. This slot 34 communi cates with a pocket 36 in the member 11 of the corresponding adjacent end of the associated molding unit-10 through an opening (Fig. 4) 37 in the associated leg'16 of the shoe 12. The opening 37 in the rear of the unit 10 is preferably of the same shape asthe slot 34.
It should be also noted that the member 26 is provided with a pocket or. opening 40 which communicates with a slot 41 in the extension plate 20. The slot 41 has a reduced portion 42. Also, the slot 41 is adaptedto co-operate with a similar slot 43 formedin the member 26 which communicates with the poeket or opening 40. Now, as will be readily obvious from the illustrations in Figures.3, 4 and 5, the. free ends of the plates 20 and 28 aresecured to the adjacent and co-opera'ting apertured parts by means of wedges 45.
The wedges are all of the same construction my novel eneral utility wedge.
and I preferably associate two of the wed es with each plate. I have illustrated the we ge in perspective inFig'ure 18 of my drawing.
1 shall now describe this wedge in detaiL The wedge 45 comprises a body portion46 and a pair of lateral ears 47 and 48 which extend in opposite directions and which constitute the head of the wedge. The wedge is tapered in construction and has a pair of. openings 49 and 50 adapted to receive other similar wedges. Each wedge is'also provided with a lateral projection 51, the purpose of which will be more fully described herein.- after in connection with the various uses (if Now re erring again to Figure-3, it will. be obvious that the head ofthe wedge 45 is adapted to be inserted through the cooperating slot in the plate 20 and the member 26 and into the pocket '40 of the member. By. sliding the wedge over to a position in rear of the reduced portion 42 of' the slot,
the lateralears 47 and 48 of the wedge 45 will engage the wall of-the pocket 36 and" thusbe maintained in a given position. Then, another wedge 45 may be pushed in .the slot 50 of the other wedge .45, which second Wedge will serve to cause the extension of the plate 20 to tightly engage the 'outer wall of the member 26, thus binding the units '10 to the wall 26.
The plate 28 may be secured to the associated unit 10 by a pair of wedges 45 in much the same manner as the extension of the plate 20' is secured to the member 26. The
pair of co-operating wedges will serve to cause the plate 28 to tightly engage the outer wall of the associated unit 10. It will be apparent, therefore, thatiby using the above described construction the ,units 10- may be tightlv connected tothe corner member 26.
Also, by'removing the screw 31, as previously described, the'plate 28 may be swung to the dotted. position illustrated in Figure 5 when the associated wedges 45 are removed therefrom. This permits of the ready disconnection ofthe units from the. corner piece 26 after the cement has set.
Referring now toFigure 7 it will be observed that apanel for molding the walls of .a house is adapted to rest upon the inclined edge 17 of the base mold 10. I have designated the panel by the. reference numeral 1 60 and shall now proceed -to describe the panel in detail. "The panel 60- (Figure 20) comprises essentially a sheet metal front base 61 having mounted thereon a plurality of wooden .cleatsor slats 62. The lower edge to maintain the panel 60 in alignment withis to say, the bent portion 64 of the sheet 61 is bent so that it will seat on,'the inclined edge 17 of the bottom mold.- I have indicated the inclined portion of the portion 64 by the be reenforced by a plate 68. As illustrated in Figure 20, the portion 67 of the flange 64 is equipped with a plurality of slots 68' similar to the slots 34 and 41 previouslydescribed. These slots are adapted to receive the heads of wedges in :much the 'samemanner as the slots 34 and 41 receive the wedges. Each of the wedges 45 when mounted in the aperture". 68"extend outwardly from the panel 60 (Fig. 7) and are adapted'to have inserted through the openingthereof another wedge 45 which serves the bottom mold 10. Also,.these wedges 45 serve to prevent the panel from becoming dislocated with respect to the bottom mold 10.
Now referring again tofiFigure 20, it will be noted that the top edge of .the sheet 61 is bent back upon itself, as indicated at 70, forming a strip 71 which is suitably fastened to the cleats 62. Now the upper part of the turn back portion 7 O is equipped with a lonitudinal groove 73, as best illustrated in igures 20, 21 and 8. The purpose of this groove will be more fully explained in conjunction with my novel ceiling cornices which will be described hereinafter.
Each of the sides of the panel 60 illustrated in Figure 20 are formed identically the same. Therefore, itis believed the description of one side will suflice for both. Eachside of the panel is formed so that a portion of the sheet 61 overlaps the cleats 62,- as indicated at 75. Formed integral with this overlapping portion 75 is a lateral extension 76 which includes a hook portion 77 and a reenforcing rib 78' (Figure 12) Also, as best shown in Figure 12, the molding panel '60 is connected to the overlapping port1on75 by means of a lateral extension 7 4-formed integral with the sheet'61. The reenforcing rib 78 is secured to the cleats62 by means of nails 79. Now, when the panels are'positioned edge to edge, as illustrated in Figure 12, thehooks 77 of'the adjacent panels are adapted to co-operate with my novel clamping means to insure of a rigid connection between the adjacent panels. Also, these clamping hooks 77 enable the proper alignment of the panels, as will be more fully explained hereinafter.
. It will be noted from the illustration in Figure 20 that the cleats 62 are disposed in the slanting position. This slanting of the cleats enables the cleats to be used as wed es for urging the edges of the panel outwar y. "That is to.say the cleats, are pushed down,
one upon .anot er, under the turnback por- Qtion 75, with their ends in en agement with the side edges of the panel.' eseslanting cleats serve to prevent buckling or bending ofthe panel in a lon itudinal direction. They also insure a e ectl true molding surface on the front ace oft e panel.
I have illustrated the clamping means in detail in Fi re 12. This device is designatedgenera ly by the reference character 80. It comprises essentially apair of clamping 'aws. 81 and 82 adaptedto engage with the 00k portions 77. on the associated edges of the panel 60. The clamping jaws 81 and 82 are identical in construction, -A detail view of one of the j aws'is illustrated inFigure 15. The jaw comprises a hook portion 83 for engagement with the hook portion 77. Also,
each jaw is provided with three openings 84, i
p and 86. The opening 84 is preferably vcircular in form'and the opening 85 is preferably irregular in shape. The aperture 86 is rectangular in formationand is adapted to accommodate one of the wedges 45. Now the clamping jaws 81 and 82 are adapted to be associated with each other in such a manner that their various openin 's' register. A wedge 45 is then inserted in he openings 86 of the two jaws and serves to tie the jaws to-' gether. Associated with the jaws is a guide element 88 (Figure 14) having a slot 89 and a pair of apertures 90 and 91 adapted to be associated with the apertures 85 and 86 of the clamping jaws. The aperture 91 is circular in shape and the i aperture 90 is somewhat larger than the aperture 91. The slot 89 is adapted to accommodate a wed e 45, the purpose of which will be more ully explained hereinafter. Then, too, the two jaws and the element 88 are ada ted to be secured together by means of a pa1r.of bolts 93 and 94. ,The bolts 93 and 94 are each provided wlth a nut 95 (Figure 13). The openings 85 are somewhat larger than the shank of the associated bolt 94 and the o ning 90 in the guide element 88 ii'tlarger till the bolt 93. Thus will be seen that I have provided a lost motion connection between the jaws 81 and 82and the guide element 88. Associated with the guide element 88 is what I preferably term a stiffener 100. Referring to Fig. 10 it will be noted that the stiffener comprises a longitudinal T iron l 01 provided with a trussed construction consistmg of an L iron 102 and side plates 103 which connect the two irons 101 and 102. The L iron 102 has its ends bent inwardly towards the T iron 101 to which the ends are fastened, as indicated at 104. The ends of the stiffener are each provided with a lateral projection comprising a T iron 105 (Figure 11). The purpose of this T iron 105 will be explained hereinafter. l
Now, as illustrated in Figure 12, the base of the T iron 101 is adapted to be placed perfectly flush with thein'ner edges of the joinn the shank ofing' panels 60. The projecting leg of the T iron 101 enters the slot 89 in theguide element 88. The wedge in the slot 89 serves to urge the T iron 101 towards the adjoining panel 60 and also serves to urge the guide element and clamping jaws 81 and 82 outwardly. This results in the hooks 83 drawing the hook portions 77 away frolnthe associated panel 60; Also, the clamping jaws are urged towards each other by means of the wedge 45 which serves to pivot these aws inwardly. Once the wedges45 are in position in my novel clamping device 80, a screw 106 is threaded into anaperture 107 in the guide element 88 until its end abuts the associated portion of the T iron 101. This screw in reality constitutes a set screw for preventing the clamping device 80 from sliding along the T iron. Now it will be obvious that the clamping device 80 is guided in its action by the T iron 101 oftlre stiffener 100. Also, it will be apparent that the device serves to at all times maintain the stiffener in tight engagement with the rear edges of my novel molding panels 60.
The T iron 101 of the stiffener 100 (Figure 7), referring more particularly to the lower end of the stiffener, is adapted to set in the shoe member associated with the base mold.
The flange of the T iron 105 is adapted to abut the lateral extension 15' of the shoe 14. Then, too,.the base of the T iron 101'abuts the other leg 16 of the angular element 12. Thus it will be seen that the-lowerpart of the stifl'ener 100 completely occupies the space separating the vertical leg of the angular element 12 and the extension .15. Obviously, any stresses imposed upon the stifli'ener 100 will be transmitted through the iron 105 to the shoe 14, and more particularly to the 1 lateral extension 15. As previously described,
the panels 60 are adapted to rest upon the slanting edges 17 of the base mold 10. Also the panels at thescorners of the structure being molded are adapted to rest upon the slanting edges 17 of the associated corner base molds 25. The panels at the corners also abut 'at theii; rear edge an upwardly extending projection 18' on the base'mold 251(Figure 6). I
In Figure 1, I have illustrated a substantially complete molding device embodying the features of my invention. The base molds 10 arepositioned upon the previously,
molded structure designated generally by the reference character That is to say, after;
one story of a given structure has been molded, such as the story 110, the molding panels and devices are removed from themold after it is set and are a-gain'set up in position upon the finished story ready to receive another pouring of cement. In Figure 1, I have-also designated generally by the reference character 111 a part of a scafiold;
scribed. Now in order to maintain the stiff- Vided with a hook-like portionada te to end 114 is in this shoe it will of course, be
structure to be poured. Positioned intermeto tie the cement on opposite sides of the 'core device which may be of any usual or conventional configuration.
In practicethe base molds are first placed upon the structure 110 and the molding panels are then positioned on the slanting edges of .the base molds. Thereafter, the stifi'eners are associated with the molding panels. Also the lower end of the stifi'eners are disposed 1n the corresponding shoes, as previously deeners in position until the cornice molds are in place, I preferably provide each stiffener with a resilient device such as that illlIS'. trated indetail in Figures 29 and 30. The device consists simply of. a spike 112 driven into a cleat 62 of the panel and a spring 113 surrounding the shank of the spike having one edge 'dlsposed over an edge of thecleat 62. v The other end 114 of the spring is reco-operate .with the T 101 of the sti ener to hold the same in position until the upper end of the T is set in a suitable shoe associated with the ceiling'cornice. When the in'the position indicated by otted lines in Figure 30. Q I In Figure 1 I' have illustrated a pair of spaced panels-60 which define wall ofthe diate the spaced panels 60 is a hollow wooden' core member 115 WhiGh'iS ada ted to define a dead air pocket in the wall eing poured.- As is well knownto those familiar with the molding art, this pocket serves as a heat insulator in addition to serving to prevent the accumulation of dampness. Extending through this core member 115 are a lurality of iron reenforcing elements 116 which serve member 115 together.
As best shown in Figure 2, the panels 60 may be'connected at the corners by means of course, it is to be understood that the corner j pieces 120 and 121 are associated with the base corner molds 25. a
Referring again to the base mold 10, it
be observed thatthe-shoe's-associated with the opposite panels, are tied together by means of steel bands 125. Each of these bands is disposed immediately under the base mold and the core member 115 (Fi re 1) and has one end formed into a latera exten- 126 pped with a hook portion adapted to fit 9W1 h lateral] extension 15 we of the associated shoe 14. The other end of eachband is equipped with a device such as that illustrated in Figure 41. I have designated this device generally by the reference character 128. This device is adapted to abut the extension of the shoe 14. That is to say, one end of the band 125 has a portion for hooking over a portion of one shoe, and the other end of the band has a device 128 adapted to co-operate with the extension 15 of the opposite shoe. Thus the two molding walls or panels are tied together against lateral expansion.
The device 128 comprises a member 129 having a recess in its lower portion 130for accommodating the band 125 and being equipped with a plurality of projections 131 for fitting in corresponding apertures in the band 125. In practice,'the projections 131 of the member 129 are first inserted into the corresponding apertures in the end of the i band 125 and then the member 129 is placed in a position adjacent the associated edge of the shoe (Figure 5). The member 129 is provided'witha-clamping plate 135 having a slanting edge136 for engaging a correspond ing edge on the strip of material 125. The
plate 135 is preferably secured to the member 129 by means of bolts and nuts 137. Also, the plate 135 isadapted to be tightened in place y means of a screw 140 threaded into the member 129. It will thus be apparent that I have provided an excellent device adapted to abut the corresponding shoe and to tightly maintain in place the corresponding end'of the band of material associated therewith.
' be described hereinafter. As shown in Figure 1, a plurality of tie bands extend across the upper ends of the associated panels 60.
I have designated this band generally by the reference character 141. The band 141 has a tongue portion 142 adapted to fit in the longitudinal groove 7 3 in the corresponding panel. 'Each band 141 has two of these tongues. I have indicated one of these tongues by the,
referencecharacter 142 and the'other by the reference character 142-. It should be understood that each .of thebands 141 will lie in a ;-recess 74 in the associated panel 60.
Referring to Figure 8, it will be noted that each end of-the band 141 is equipped with an aperture 144for receiving any suitable wedge .145. Associated with this wedge 145 is a-cornice member 150, which will be described hereinafter.
Mounted upon the top of the outer panel is a top mold member 146 (Figure 19) which comprises a sheet metal molding wall 147 having a lateral extension 148 extending outwardly from the panel. This extension 148 has a lateral projection 149 adapted to cooperate with the T iron 105 of the associated stiffener 100. The extension 148 is provided with a plurality of apertures 149 through which wedges 151 are inserted (Figure 1). The wedges 151 are adapted to extend througlY corresponding openings in the associated tie bands-141 to tiethe bands to the top mold member 146. The top mold memberp146 has its extension 148 formed with a longitudinal tongue 153 adapted to be inserted in the corresponding groove 73 of wall panel 60. Thus it will be seen that the top mold member 146 is utilized to maintain the tongue 142 of the band 141 in place in the longitudinal groove of the associated panel. y Y
The cofnice member 150 is illustrated in perspective in Figure 16. This member is preferably made of sheet metal and comprises an arcuate shaped portion 160 having'formed integral therewith a substantially flat portion .161 adapted to normally be disposed in a horizontal plane. The portion 161 has a portion 162 turned back upon itself forming a lateral extension 163. This lateral extension 163 is adapted to extend over the edge of the T iron 105 (Figure 8'). As best shown in Figure .8,
the extension 161 and the lateral projection 16 3in reality constitute a shoe for receiving the end of the stifi'ener 100. The stresses imposed upon the stiffener are adapted to be transmitted through the T to the lateral extension 163 of the cornice member 150.
The horizontal extension 161 of the cornice member 150 is equipped 'yvith a plurality of .square' openings 170 for receiving the previouslydescribed wedges 145. The lower ends of these wedges (Figure 8) are adaptedto abut the upper end ofthe rear face of the associated panel 60.- These wedges prevent the bands 141 from slipping out of place. The extension 161 is :also equipped with a plurality ofapertures 172 through each of which one jaw 173 ofa clamping device 174 is adapted to be inserted (Figure 8). The clamping device 174 serves to tie the cornice piece 150 to the associated panel 60. The lower end of the j aw 17 3 is pivotally attached to another jaw member 17 6 having a portion adapted to engage the under edge of one of the slats 62 in the, panel 60. I have designated this jaw portion by the reference numeral 175. The
member 176 (Figure 9) has a portion 176' turned back upon itself to form a pocket for receiving one of my' novel wedges 45. The
member 176 and the portion 17 6' are attached to the end of thejaw member 17 3 by means of a pivot bolt and nut construction 177. The
' side of the jaw 173 is equipped with a plurality of corrugations 178 against which the upper edge of the wedge is adapted to abut. Now once the wedge 45 is in place in the pocket formed by the member 176, the upper edge of the wedge will tightly abut the corrugations 178 which will serve to prevent up-' ward displacement of the wedge. By forcing the wedge in position, both of the jaws, due
to the pivotal mounting, will be drawn together thus causing the cornice mold 150 to be drawn into a tight engagement with the upper end of the molding panel 60. This clamping device may beused in many other analogous capacities in the molding art construction.
For example, I have provided the mold member 146 (Figure 19j with a plurality of apertures 153' through each oi. which a aw 17 3. may be inserted to clamp the mem- I her 146 to the associated panel 60 in the same manner as described in connection withtho construction illustrated in Figure 8.
The cornice mold 150 is also provided with a lateral edge 180 (Figures 8 and 16) hav- '25 ing a right angle portion 181 bent back over itself. This portion 181 forms a pocket for a purpose to be hereinafter described. The portion, 181 includes a hook portion 182 which is adapted .to'be used in conjunction with aclamping device. Eaclfof the pockets 181 are'adapted to receive an edge of a longitudinal Wooden beam 185, such as the beam illustrated in Figure 1. These beams willeach be secured to the cornice member 150 by means of a'clamping band 186 having its ends'formed into hook portions 187 for tying the hooks 182 of the adjacent cornice "members together. A.wedge 188 may be-inserted intermediate the band 186 and the. beam 185. Now the beams 185 are adapted to support ceiling panels 200, which will now be described.
Referring to Figures '24 to 28, inclusive, it will be noted that each panel comprises a sheet metal molding surface 201- reenforced by a plurality of wooden cleats 202. In construction the panels 200 may be much the same as the panels 60. The corner of each panel 200 is equipped with a small cornerpiece of metal 203 (Fig. 28) having an aper ture 204 for receiving a nail,'s crew, or the like. I The edge of each panel is provided at its ,rear face with ahook portion 206, such as. the portion 77 described in connection with my molding panels 60. The portions 206 of adjoining panels areadapted-to form a'pocket-for-receiving one of the wooden beams 185. 9 i
4 The hook portions206of the ceiling panels 200 maybe secured together by means of a clamping band 186. A wedge188'may be inserted' betweenthe band 186 and. the beams 185. The corners of the panels 200, are sen, cured to the beams by means of nails 210 extending through the apertures 204.
I 105 abuts. It is. this shoulder that takes Now from the foregoing description it will be obvious that I have provided a readily demountable molding construction for molding an entire story of a building at one time. My invention, however, is not to be limited b the detailed disclosure which I have ma e, but only insofar as defined by- Since both the panels and the sti fieners are the same as that already described in detail, it is bel eved that it will not be necessary to redescribe these parts. Associated'with the lower end of each of thestifi'eners'lOO is a I wooden shoe member 215 having an upward projection 216 which defines a ocket for re- I ceiving the T of the end 0 the stiffener 100. The lower end of the panel 60, is adapted to rest upon the wooden shoe 215. The
shoes of the adjacent; pancls are tied to gether by'means of tie bands 217. One. end I of the tie band 217 is provided with a lateral extension 218 and a nail 219. This lateral projection 218 abuts the side of the wooden shoe 215.
The other end of the tie band 217 may be secured to a device such as that illustrated indetail in Figure 41. I have designated this device in Figure 32 generally by the reference character 128'. This device is adapted to abut the outer edge of the shoe 215 and to 7 tie the two shoes together. I
The upper ends of the panels 60 are provided with a pair of shoes, 215' substantially the same as the wooden shoes 215. These shoes 215' aie tied together by means of tie bands 217... Each of these bandshasa lateral extension 221 dapted to be fastened to the edge of one shoi other shoe. The extension 222 is also vided .with an inwardly extendin hookike portion 223' ada ted to fit over t 0 base of no 5 and a lateral extension 222 adapted to be fastened to an edge of an- II the T iron'105 o the associated stiffener 100.
()bviously'dthe, stresses imposed upon the' stiflener 100 will be transmitted through the T iron 105 to'the shoe associated therewith.
The shoe in turn will transmit the stresses projection 216 of the shoe in reality consti tutes a shoulder against whichthe Ti iron stresses imposed upon the stiffener.
In Figures 34 and 35 I have illustrated to the tie band. It will be notedthat the i the still another modification of niy invention.
In this formof the invention the same panels 60 or'200 are employed as were used in my first modification of the invention. The
of a suitable clamping band 231 in much the panels 60, however, in this construction are positioned one upon another. In other words, this construction is adapted to be used where itis desired-to build a relatively hi h wall. The panels, however, in this form 0 the invention are reenforced by wooden beams 230. I
The beams 230 are-tied to the panels by means same manner as the band 186 was tied to the hook portions 206 of the ceiling panel 200.
Extending between the panels 60 is a phi-- ralit of tie bands 232 Theends of the tie ban s 232 are adapted to be secured to a transverse beam 233'associatedwith the longitudinalstifiener beam 230. The tie bands.
232 will serve to tie the panels together intermediate the ends of the wall, so as to reenforce the panels at this point. Each ofthe bands 232 is equipped with a lateral extension sary to em loy two or more panels, one upon another. he panels should be reenforced intermediate their ends by tie bands, such as the bands 232. I have found the arrangement illustrated in Fi res 34 and 35 an ideal one, as far as a relatlvely high wall-is concerned. r
In Figures 36 to 40,"1nclusive, I- have illustrated a'modified form of molding panel.
This form of the panel is inherently stiff and hence does not require any stiifeners 100.3
This form of anel is ideal for molding foundations and the like in a given building construction.
Each panel comprises a sheet metal molding surface 250 having its edges formed into a lateral extension 251 which defines the edges of the panel. .Formed integral with the extension 251 is a right angle portion com prising a pair of legs 252 and 253. The legs 252 and 253 are,,disposed at right angles. to each other. The leg 252 co-operates with the edge or lateral extension 251 to form a pocket for receiving a plurality of'woeden cleats 254. The cleats 254 may be disposed in a slanting position and wedged in place in muchthe same manner as was the case with the cleats 62 in my panel p It should be noted, as best shown in Figure 36, that only the sides of the panel are formed with the angular portions previously I described. Theends of the panel are eacli provided with a lateral extension 256 adapted to accommodate transverse wooden bars 257'. Each of the angular portions comprising the legs 252 and 253 are adapted to receive longitudinalstifiening wooden bars 257. The bars 257, together with the bars 257; define the periphery of the panel as far as itsrear 7 adjacent basemold.
The angular portions are preferably secured to the cleats 254 by means of nails 1ammered into the cleats at a diagonal angle. I have indicated the nails generally by the ref-- erence character 258 (Figure 39). The legs 253 of the angular portion are fastened to the corresponding wooden stifli'ening bars 277 by means of nails 259. Also, the reenforcing bars 257 are fastened to the cleats 254 by means of angular nail elements 260. Each of the nail elements 260 includes (Figure 40) a pair of nail portions 261 and 262 disposed at right angles to each other and connected to The wooden bars 257-and 257' are in turn interconnected by a plurality of wooden bars 265 fastened to the rear of the cleats 254. These wooden bars 265 serve to reenforce the wooden bars 257 and 257 and to stiffen the panels. p
