8 Claims. (CL 189-46) This invention relates to improvements in demountable metal partitions and more particularly to an improved door frame assembly which is interchangeable with the panel units thereof. This application is a division of our copeuding application Serial No. 228,025 filed May 24, 1951.

This improved demountable metal partition comprises flush panel units, glazed panel units, and door frame units having similar shaped framing uprights which greatly simplifies fabrication and interchangeable erection of the separate units. The flush panel units are each assembled from a pair of wall facing sheets interiorly faced with a sound deadening layer, and are provided with rebent edge portions designed to engage the outturned flanges forming a part of the framing uprights. The same framing uprights used in forming the panel units are also used in forming the door frame units.

The door frame units are stiffened and strengthened by uprights similar to those used in the panel sections and are interchangeable therewith. The door frame unit incorporates a sheet metal door frame embracing the framing uprights, the door being hingedly mounted to the adjacent framing upright. The sheet metal door frame carries a resilient striker against which the horizontal and vertical edges of the door snugly and silently seat when closed.

As a feature of this invention, a floating door frame assembly is provided stifiened and strengthened by the framing uprights to which a fixed guide frame is secured. The floating frame which receives and supports the hinged door is constructed to telescope within the fixed guide frame to permit field adjustment of the lower edge of the door as mounted therein to clear any floor covering placed underneath the door. Means are provided for adjustably securing the floating frame and its associated hinge plates to the adjacent sturdy framing uprights so that the weight of the door is transmitted directly thereto. Devices are also provided for vertically adjusting the floating frame, conveniently accessible after the floating door frame section has been installed as a part of the partition run.

This improved demountable partition may be economically manufactured from a minimum number of parts and erected with minimum fitting in the field to accommoda'te substantially all field conditions.

Various other novel features and advantages will be apparent from the following description considered in connection with the accompanying drawings, in which;

Fig. 1- is intended to illustrate a typical installation of this demountable metal partition wherein the partition is shown erected on the building floor W over which a .ceilingZ extends, the partition runs being joined to a vertical building wall Y. The installation shown in Fig. 1 illustrates the manner in which this partition may be erected to satisfy straight run, angular run, and T- run conditions as normallyencountered in the field.

The partition as illustrated comprises a series of erected partition units including flush panel units .A, glazed panel units A and door frame units J which may be interchangeably arranged as desired. The partition units are shown capped by acornice-assembly E with a ceiling filler assembly H mounted onthe-cornice assembly and extending to the ceiling Z. A wall, filler assembly G is shown in abutmentyagainst the permanent wall Y of the building, filling the space between the wall Y and adjacent glazed panel section A 7 Partition unit supporting and leveling devices B, as "shown in Figs. 21, 22, 28 and 3.1, each comprising a floor-block having Vflat leveling shims 65 capped by an aligning shim 65', are secured .to the flooralong the partition run and positioned between the adjacent vertical edges of adjacent partition section to level the partition sections and maintain them in accurate alignment.

The adjacent vertical edges of the partition units arranged in straight run alignment are'detachably connected by normally concealed run connecting clips C normally covered by removably pilaster caps D'resiliently secured to the connecting clips. The inner corners of adjacent angularly-extending partition units are detachably secured together by inner corner connecting clips, and the outer corners thereof are' detachab'ly secured together in rigid assembly by outer corner connecting clips normally concealed from view by a corner pilaster c'ap D which is resiliently but removably secured to the attached outer corner connecting clips.

frame assembly I. The lower ends of the door frame uprights are covered by plinth blocks 255 against which the adjacent ends of the baseboards 124 abut.

The cornice assembly E comprises a continuous cornice frame of I-beam formation which caps the erected partition sections and greatly strengthens the erected partition. The cornice frame, providing a twocompartment wiring raceway, is capped on each side thereof by removable cornice covers 106. v a

By removing the cornice covers from the cornice frame, the baseboards 124 from the floating base frames and the pilaster caps D and D from the partition section connecting clips C, complete access may be had for the installation or repair of conduits and cablesleading to outlets installed at any desired location on the erected partition.

Panel units The interchangeable flush panel units A, presenting substantially flush facing surfaces throughout their height and constructed more particularlyas illustrated in Figs; 2 to 5 inclusive, comprise vertical and horizontal framing members constructed and assembled to provide a strong framework which support the panel facing sheets. The panel framework comprises a pair of framing uprights 1 each formed from a single strip of'relatively heavy sheet metal rolled into double S formation as 'illustrated in Figs. 2,3 and 4 to provide a main'web' 2, a pair. of parallel extending'inner legs 3,;and a pair of intermediate webs 4 flaring outwardly from the inner legs 3 extending substantially parallel to the main web 2 the intermedi'ate ,webs 4 each terminating in an outturned outer leg 5 spaced from and extending substantially parallel to the inner legs 3. 1 I

The framing uprights I extend the full height of the panel unit and are connected together by a series of horizontal extending spacing channels 16 which are spaced at distance of one to two feet apart. Each spacing channel 16 comprises a web portion 17 and side" flange portions 18 as shown more particularly in Fig. 2. A pair-of struck out tongue elements 19 extend from each end of the spacing channel and are designed to be inserted into 1 corresponding tongue receiving slits 7 cut through the 1 of the stretcher stud 23.

After assembly of the panel unit has been completed, the inserted tongue elements I9"may be bent or twisted to secure the spacing' channel 16 to the fram ing uprights 1. V V l v V Each spacing channel 16 may be reinforced by forming a longitudinal extending reinforcing rib'20 in the web p'ortion17 thereof. O ne end of each spacing channel is formed to present a pair of alternate spanners' 2liiwhi'ch" are bent downwardly 'iuto arcu'ate shape and a pair ofintermediate spanners 2l which are bent upwardly into arcuate shape. The companion spanner-s21 and 2 1' are internally threaded and are shaped to 'provide a threaded hole of uniform diameter designed to receive the threaded shank portion of a stretcher stud 23 as shownv in Fig.2. A clearance slot separates the adjacent end of the reinforcing rib 20 from the threaded spanners to provide room for the inserted end ofthe threaded shank portion:

The stretcher stud 23 presents a flared base portion 25 of substantial area designed to snugly seat against the inside face of the main wch2 of the adjacent framing upright 1 as shown in Fig. 2 ,win1 theround neck portion 26 thereof extending through a corresponding hole 6 in Y the adjacent framing upright 1 so that the hole-6pm- The floating base assembly F extends along the building floor with its base frames contained between theframinguprights ofthe panel units,ithe base frames being normally concealed: by removable baseboards 124 extending along each side of the partition runs, providing an attractive finishing which conceals floor irreguvides a bearing therefor. The rounded neck portion terminates ina rectangular headportion26 to, which a wrench may be 'applied to manipulate the spreader 23.-

' A Wall forming panel sheet 10 is mounted oneach side 7 of the framingformed by the vertical uprights land the horizontal spacing channels 16. As slrown in Fig. the facing sheet10 presents a squared edge portion 11 along each vertical edge thereof which terminates in a rebent =lip portion 12. The upper horizontal edge of the facing sheet 10 is also provided with a squarededge portion 13 which terminates in a downturned lip portion 14. The inside face of each panel sheet 10 has a fibrous backing sheet 15 cemented thereto and covering substantially the entire inner surface area thereof as shown in Fig. 2. The fibrous backing sheet 15 is preferably made of a fibrous felt which has sound-deadening qualities.

In assembling the flush panel unit A in the form shown in Fig. 2, the uprights 1 are applied to one of the panel sheets, and the spacing channels 16 placed therebetween. Insulating filler 29 is then placed in position between the framing uprights 1 and the spacing channels 16. The second facing sheet 10 may then be telescoped endwise over the outer legs of the framing in the manner of a sliding cover, with the squared edge portions 13 of the panel sheets hooked over the outturned flange portions 18 of the uppermost spacing channel 16 in the manner shown in Fig. 2. By means of a suitable wrench, the head portions 26' of the spreader studs 23 projecting through the holes 6 is the adjacent framing upright are manipulated to spread or separate the framing uprights 1 until the facing areas of the facing sheets are stretched or drawn taut to place the desired drum head tension on the facing sheets 14}, thereby removing all waves or irregularities, providing a wall surface of precise smoothness. This stretching action also serves to press the insulating sheets attached to the interior of the facing sheets 10 against the flange portions 18 of the spacing channels 16, thereby preventing subsequent buckling of the facing surfaces or the production of metallic ring when the facing sheets are drummed upon.

As shown in Fig. 2, the lower endportion of each framing upright 1 extends somewhat below the lower edges of the facing sheets 10 to provide room for wiring and conduits therebelow which maybe strung through aligned openings 9 provided in the main web 2 of the framing uprights. Lug plates 27 are also secured as by welding to the upper ends of the intermediate webs 4 of each framing upright as shown in Figs. 2 and 7. Each lug plate 27 presents a pair of upwardly projecting spaced lug portions 27 each provided with a hole 28 therein for" receiving a cornice securing key to thereby detachably secure the cornice assembly to the partition units.

Each glazed panel unit A as illustrated in Figs. 6 to 9 inclusive, is constructed from a pair of framing uprights 1 upon which panel forming sheets 10' are mounted to extend to the desired height. The lower half section of each glazed panel unit A is constructed similar to the flush panel units A illustrated in Figs. 2 to 5 inclusive and heretofore described, and wherein spacing channels 16 are employed as shown in Fig. 2 having tongue elements 19 inserted into corresponding slits 7 formed in the framing uprights 1, spreader studs 23 being associated with each spacing channel 16 whereby the desired tension may be applied to the panel facing sheets 10'. The upper horizontal edge of each panel facing sheet 10 is provided with a squared edge portion 13 designed to seat over the free edge of the adjacent flange portion 18 of the uppermost spacing channel 16 as shown in Figs. 6, 7 and 8 and terminates in an upturned lip portion 14 to fit the superimposed sash frame 30.

The space between upper sections of the framing uprights 1 is designed to receive the glazed sash frame 30 which comprises a pair of vertical framing members 31 and a pair of horizontal framing members 36. Each vertical and horizontal framing members 31 and 36 as shown in Figsy7 and 9 comprises a web portion 32 terminating in outturned flange portions 33. Each outtu-rned flange portion 33 presents an outwardly offset facing portion 33 and has a squared vertical edge portion 34 terminating in rebent lip portion 35 to thereby provide guideways for the sash frame when telescoped between the framing uprights 1. a.

Mouldings are provided to removably retain a glass pane 41 within the sash frame 30 as shown in Figs. 7 and 9. The glass moulding may comprise fixed moulding strips 42 assembled to provide a fixed moulding frame. Each fixed moulding strip 42 presents a base portion 43 which may be secured as by welding 43' to the adjacent base portion 32 or 37 of the respective vertical or horizontal framing members 31 and 36. Each fixed moulding strip 42 presents a groove forming wall portion 44 rising from the base portion 43 thereof which merges into the attractively contoured moulding portion 45 which terminates in an inturned foot portion 46 seating against the base portion of the adjacent framing member. An offset flange portion 47 terminating in a flared lip 48 extends from the base portion 43, the offset flange portion 47 being formed to resiliently retain a removable moulding strip 50 associated therewith. The adjacent ends of the fixed moulding strips 42 are beveled and interfltted to provide a finished moulding frame.

Each removable moulding strip 50 is constructed to be applied to the opposite face of the installed window pane 41 and to removably interlock with the offset flange portion 47 of the fixed moulding strip 42. Each removable moulding strip 50 represents a groove forming wall port-ion 51. The wall portion 51 merges into a moulding portion 53 corresponding in contour to the moulding portion 45 of the fixed moulding strip 42. The moulding portion 53 is provided with an inturned flange 54 ter-v minating in a flared lip portion 54. The removable moulding strip 50 is applied by inserting the flange portion 54 thereof under the resilient offset flange portion 47 of the fixed moulding strip 42, with the foot portion 52 of the removable moulding strip seating against the base portion 43 of the fixed moulding strip 42. The adjacent ends of the removable moulding strip 50 are beveled so as to interfit together to provide a substantially continuous removable moulding frame. Putty or mastic 55 is inserted in the groove formed by the wall portions 44 and 51 of the moulding strips to secure to glass pane 41 in position.

The fully assembled sash frame 30, with the window pane 41 installed and retained therein by the moulding frames 42 and 50, is telescoped into the space provided therefor between the upper portions of the framing uprights 1, with the secondary flange portions 5 thereof serving as trackways for the vertical framing members 31 of the sash frame. The sash frame is pushed into position until the squared edge portions thereof are brought into seating engagement with the squared edge portions 13' of the adjacent panel sheets 10'. As thus assembled the offset flange portions of the lower framing member 36 are flush with the outside face of the adjacent panelsheets 10'.

Panel supporting and leveling devices The panel sections A and A are erected and maintained in alignment on the building floor in the manner shown in Fig. l by panel supporting and leveling devices B constructed as illustrated in Figs. 21, 22, 28, 31 and 32. Each panel supporting and leveling device B comprises a panel aligning block secured to the building floor and having one or more panel leveling shims telescoped thereover. Each floor aligning block 63, as shown in Figs. 31 and 32, has a base portion to rest on the building floor, a pair of opposite side wall portions extending upwardly therefrom, and flanges extending inwardly from the side wall portions to provide a substantial rectangular shaped floor aligning block. A suitable lag bolt 64, as shown in Figs; 31 and 32, is inserted through a hole in the base portion of the block to secure the same to the building floor.

Securing screws or bolts 178 extending through the web portion 163 of vertical framing member and through the slots 177 of the floor bracket 175 provides means for adjustably securing the vertical framing members 160 and 160 to thebuilding floor. Each floor bracket 175 has a foot portion 179 through which floor securing screws 179 are inserted.

The door 171 is hingedly mounted directly to the upright 1 embraced by the vertical framing member 160, thereby providing a strong and sturdy hinge mounting for the door. As shown in Figs. 10, 12 and 13, the door 171 is hingedly mounted on three hinge mounting plates 180 stamped from relatively heavy metal plate, each presenting a raised body portion 181 to which the hinge leaf 182 is secured as by screws 183. The raised body portion 181 of each hinge mounting plate 180 terminates in depressed flange portions 184 at each end thereof which are secured as by screws or spot welds 184' to the secondary base portions 4 of the upright 1. Each hinge mounting plate 180 is so shaped that the raised body portion 181 thereof will abut the inside face of the web portion 163 of the vertical framing member 160 which embraces the upright, thereby maintaining the squared edge portions 174 of the vertical framing member 160 securely locked to the secondary flange portions 5 of the upright. A rectangular hole 185 conforming to the shape of the hinge leaf 182 is cut in the web portion 163 of the vertical framing member 160 to permit the hinge leaf ot snugly project therethrough.

The vertical upright 1 embraced by the companion vertical framing member 160' also has a mounting plate 186 associated therewith to which the door lock plate 187 is secured, as shown in Figs. 10, ll and 19. The mounting plate 186 has a raised body portion 181 terminating in depressed flange portions 184 which are secured as by spot welds 184 to the secondary base portions 4 of the upright 1 embraced by the companion vertical framing member 160'. The lock plate 187 is secured to the body portion .181 of the mounting plate 186 as by screws 187, and the web portion 163 of the vertical framing member 160' has a conforming hole 188 cut therein through which lock plate 187 may extend.

The facing flanges 164'and 166 of the horizontal framing member 161 likewise terminate in squared edge portions 174 and inturned lip portions 174' which are similar to the squared edge portions 39 and rebent lip portions 40 associated with the top horizontal framing member 36 of the sash frame 30 previously described. The facing flanges 164 and 166 of the horizontal framing member 161 are thus designed to seat between the rolled edge portions 98 of the cornice frame.

V The door frame assembly I is fully assembled in the shop for erection in the field with the upright 1 positioned within the vertical framing members 160 and 160 and with the hinge leafs 182 and the lock plate 187 thereto attached. The door frame assembly is erected by placing the lower ends of the uprights 1 on the adjacent panel supporting and leveling devices B, and the connecting clips applied to connect the uprights 1 of the door frame assembly to the adjacent uprights of the adjacent erected panel unit A or-A'i The top edge of the horizontal framing member 161 is leveled into alignment with the corresponding top horizontal edges of the adjacent panel sections, the floor brackets 175 then secured to the building floor asby screws 179 "and the securing bolts 178 tightened. 'As thus constructed the cornice assembly E may continue over the horizontal framing member 161 of the doorframe. This door frame assembly may be interchangeably installed with panel sections A and A of corresponding width as the building tenant may require.

There is shown in Fig. 20 a door frame I wherein the vertical framing members 189 and the horizontal framing member 190 are similarly shaped and are each formed from a single strip of sheet metal. The vertical and horizontal framing members 189 and 190 of the door frame J as shown in Fig. 20 are also similar to the vertical and horizontal framing members 160, and 161 of the door frame I shown in Fig. 14, except that the securing flange 164' shown in Fig. 14 is eliminated, and the inturned flange portion 169 is formed integrally with the web portion 163 so that the vertical and horizontal frame members 189 and 190 may each be shaped from a single strip of sheet metal. As shown in Fig. 20, the meeting ends of the facing flanges 164 and 166 of the vertical and horizontal framing members 189 and 190 are bevel cut to form flush mitered joints 191 which are secured together by a seam of welding metal 192 which also secures the adjacent abutting ends of the web portions 163 together as shown in Fig. 20. The verticalframing members 189 of the door frame as shown in Fig. 2.0 also embrace uprights 1 and are provided with hinge mounting plates and alockmounting plate 186 constructed and assembled similar to the door frame assembly I heretofore described. V

There is shown in Figs. 25 to 35 inclusive a door frame assembly I comprising a fixed frame 200 embracing a floating door receiving frame 210. The floating frame 210 supports the door 171 and can be vertically adjusted with respect to the fixed frame 200 so that the bottom of the door 171 as mounted in the floating frame 210 may be elevated or lowered with respect to the building floor. This floating door frame assembly permits vertical adjustment of the mounted door so that the lower edge thereof will swing over floor coverings of various thickness which may be placed under the door from time to time.

The fixed frame 200 comprises a pair of vertical facing strips 201 and 201' which are attached to the secondary flange portions 5 of each vertical upright 1 forming a part of the door frame assembly I". The upper ends of each pair of vertical facing strips 201 and 201' are secured to a horizontal extending framing channel 205 forming a part of the fixed frame 200.

Each of the vertical facing strips 201 and 201 present a facing portion 202 which is secured to the outside face of the adjacent secondary flange portion 5 of the upright 1 as by spot welds 202. Each facing portion 203 presents a hooked edge portion which abuts against the free edge of the adjacent secondary flange portion 5 of the upright and a rebent lip portion 204 forming a finished rounded edge 204' as shown in Fig. 26. The rebent lip portions 204 of the paired facing strips 201 and 201' as thus secured to the secondary flange portions 5 of each of the two door frame uprights 1 define an inwardly extending guide which receives the vertical frame members 211 and 211' of the floating frame 210.

The horizontal extending framing channel 205 has a web portion 206 and downwardly extending flange portions 207 designed to snugly telescope between the lower flange portions 98 of the cornice frame as shown in Fig. 26. The downturned flange portions 207 each terminate in a rebent flange portion 208 defining a finished and rounded edge 208'. The terminal ends of the flange portions 207 of the horizontal framing channel 205 abut against the rounded edges 204 of the adjacent vertical facing strips 201 and 201' at the upper end thereof and may be seam welded thereto to provide a flush butt joint 209 as shown in Fig. 26. The downturned flange portions 207 of thehorizontal framing channel 205 are detion 215 of the vertical frame member 211..

Signed to zon l member'21 2bf the floating frame 210 in a manner to permit vertical adjustment of the horizontal frame member 212 therein.

The vertical frame members 211 and 211' and the horizontal frame member 212 of the floating frame 210 are similar in construction and cross-Sectional contour, each comprising a frame section 213 and a door strike section 214 each formed from a single strip of sheet metal. The frame section 213 as shown in Fig. 26 presents a web portion '215 having afacing flange 216 extending from one vertial' edge thereof and a securing flange 217 extending from the other vertical edge'thereof. Each door strike section 214 presents a facingflange 218, a trim portion 219, a' rebent lip portion 220 and an intnrned flange portion 221,as shown in Fig. '26. The rebent 'lip portion 220 and intnrned flange portion 221 forms with the web portion 215 of the framing section 213 a receiving groove within which a resilient bufier strip 170 is inserted and adhesively secured to provide a resilient strike for the hinged door. It will be appreciated that the vertical frame members .211 and 211' and the horizontal frame member 212 'may each" be formed from a single strip ofis'he'et metal by eliminating the securing flange 217 and forniin'g the inturned flange 221 integrally with the web portion 215.

The free edge ofeach' of the facing flanges 216 and 218 is provided with a square edge portion 222 terminat ing in an inturned'lip portion 223 as shown Fig. 26. The meeting ends of the facing flanges 216 and 218 may be cut on a bevel and interiorly weldedtogether to form a smooth butt joint 224, as 'show'n' in Fig. 26. The meeting ends of the trim portion 219, rebent lip portion 220 and intnrned flange portion 221'may also be cut on a bevel and welded together to provide a smooth butt joint 224 as shown in Fig. 26. The floating frame 218 as thus constructed'rnay be vertically adjusted with the horizontal frame. member 212 telescoping within the fixed horizontal extending framing channel 205 and the vertical frame memberslZll and 211' telescoped between the paired" facing strips 201 and 201 secured to each of the door frame'uprights' 1.

The door 171 ishingedlymounted upon three mounting plates as shown in 25,.comprising a lower mounting. plate 225, an intermediate mounting plate 225 and a top mounting plate"225". Each of the three mounting plates is; constructed as shown in Fig. 33 comprising adepressed body portion 226 presenting oifset end portions 227. Each hingemounting plate 225, 225 and 225'f is positioned adjacent the ,inside face of the web portion 215 of the verticalframe member 211 forming a part of 'the flo'ati'ng frame 210, and the oifset end portions 227 thereof are secured as by spot welds 227 to the inside fac'ej of the web portion 215 of the vertical frame member'211 as shown in Fig. 31. A rectangular hole 229 is cut in the web portion 215 of the vertical frame member 211 adjacentthe depressed body portion 226 of'the mounting'plate to snugly receive the hinge leaf 228 therein, the hinge leaf 228,

being secured 'to" thedep'ressed body portion226 of the mounting plate as" by securing. screws 229'; -As fthus attached the outsidefaces' of. "the hingeleaves; 228'are substantially flush with the outside face of the web' por- A door strike mounting plate'230 is attached to, the inside face of the web portion 215 of the jcompanion vertical frame member211 as shown in Fig; 25. 'The door strike mounting plate 230 as shown in Fig. 34'is similar to the hinge mounting plates 225, 225' and 225". as shown in Fig. 33 and presents a depressed body portion 226 and offset end portions 227 which are secured as byspot welds 227 to the inside face ofthe web portion 215 of the vertical frame member 211'. A rectangular hole 229 is cut in the web portion 215 of the vertical frame member211' torreceivejthe, lockplate. 230 which isfsec'ured as' by screws'to the depressed 12 v a body portion 226 .of thedoor strike mounting plate 230,.

The floating shelf bracket 245 is positioned directly above the web portion 242 of the fixed platform member 241 and presents a horizontal extending bottom portion 246 having a threaded nut member 247 welded to the lower face thereof. The floating shelf bracket 245 has an upwardly extending flange portion 248 connected to the bottom portion 246 thereof by spaced stiffening webs 249. The flange portion 248 of the vertical adjusting device 240 associated with the vertical frame member 211 may be secured as by spot welds 248' to the adjacent offset end portion 227 of the lowermost hinge mounting plate 225. The flange portions 243 of the vertical adjusting device 240 associated with a companion vertical frame member 211 may be secured as by spot welds 248' directly to the inside face of the web portion 215 of the frame member 211'.

It will be noted by referring to Figs. 31 and 32 that the fixed platform members 241 contained within the vertical frame members 211 and 211 are substantially at the same elevation with the web portions thereof positioned directly above the cableway cutout 9 of the adjacent vertical uprights 1 as shown in Fig. 28. Each of the fixed platform members 241 supports an adjusting stud 250 which may be similar to the stretcher studs 23 associated with the panel section A heretofore described. Each of the adjusting studs 250 presents a threaded shank portion 251 terminating in a flared base portion 252 designed to seat against the web portion 242 of the platform member 241. Each adjusting stud 250 is provided with a rounded neck portion 253 designed to extend through a conforming hole 253' in the web portion 242 of the platform member. The round neck portion 253 of each adjusting stud 254) terminates in a rectangular head portion 254 extending downwardly between the flange portions 243 of the platform member and accessible for application of a wrench thereto inserted through the adjacent cableway cutout 9 of the frame upright 1. The threaded shank portion 251 of each adjusting stud 259 is threaded through the threaded nut member 247 secured to the bottom portion 246 of the adjacent floating shelf bracket 245. By an appropriate manipulation of the head portions 254 of the adjusting studs 250 contained within each of the vertical frame members 211 and 211' adjacent the lower ends thereof, the floating frame 21% with the door 171 hinged thereto may be raised and lowered as desired to elevate the bottom edge of the door the desired distance above the floor covering.

The lower ends of the vertical frame member 211 and 211' are adjustably secured to the building floor as by floor brackets 175 as shown in Figs. 27, 31 and 32 constructed as heretofore described. The upstanding lug portion 176 of each floor bracket is provided with vertical slots 177 designed to receive the securing bolts 178 extending through the Web portion 215 of the adjacent vertical frame member 211 and 211'.

The vertical frame members 1 associated with the floating door frame assembly J" above described are similar in shape and construction to the framing uprights 1 associated with the panel sections A and A. The floating door frame assembly J" is installed by inserting the fixed framing channel 295 thereof between the downwardly extending flange portions 98 of the cornice frame 94, and then placing the lower ends of its associated door frame uprights 1 in supporting position on the topmost shim 65 of the adjacent panel supporting and leveling devices B. The connecting clips C are then attached to the adjacent uprights of the door frame assembly and panel sections and the space therebetween covered by the removable pilaster caps D. The foot portions 179 of the floor brackets 175 can then be secured to the floor by the 14 floor screws 179 and the securing bolts 178 tightened to fixedly secure the Web portions 215 of the vertical frame members 211 and 211' to the floor brackets in vertically adjusted position. The panel supporting and leveling devices B, the lower ends of the pilaster caps D, and the door frame verticals may be covered and concealed from view by suitable plinth blocks 255 as shown in Fig. l'. The floating frame 210 may be vertically adjusted after the floating door frame assembly J has been installedj by removing the plinth blocks 255 and pilaster caps to permit application of a Wrench to the tightening nuts associated with the lock bolts 231 and to the headpor tions 239 of the clamp bolts 237. The securing bolts 178 are also loosened to permit vertical adjustment of the vertical frame members 211 and 211 with respect to the floor brackets 175. A wrench may then be inserted through the cableway cutouts 9 in the frame uprights 1 to manipulate the adjusting studs 250 contained in the vertical frame members 211 and 211 to permit vertical adjustment of the floating frame 210 as desired. When the desired adjustment has been completed, the securing bolts 178 are tightened, the lock bolts 231 and 237 are also tightened, and the pilaster caps D and plinth blocks 255 are replaced. This improved metal partition may be fabricated and assembled from a minimum number of parts to satisfy substantially all field conditions which may be encountered, and is so designed as to permit low cost production line fabricating and assembly thereof to provide a parti-Q tion of economical cost without sacrifice of strength and sound insulation qualities. The plant fabricated parts and sections are additionally so constructed as to permit convenient interchangeability of the'parts and low cost field erection of the partition. By changing the shaped contours of the pilaster caps D and D' the base trim members or cornice covers 106, varying architectural and artistic effects may be given to the erected partition without otherwise changing its construction.

While certain novel features of the invention have been disclosed and are pointed out in the annexed claims, it will be understood that various omissions, substitutions and changes may be made by those skilled in the art without departing from the spirit of this invention. I
