DEMOUNTABLE METAL PARTITION Filed May 24. 1951 1a Sheets-Sheet 1e United States Patent DEMOUNTABLE METAL PARTITION Robert C. Johnson and Ralph S. Millard, Jamestown, and Reuben T. Carlson, Scarsdale, N. Y., assignors to Steel Partitions, Inc., Jamestown, N. Y., a corporation of New York Application May 24, 1951, Serial No. 228,025! Claims. (Cl. 18934)' This invention relates to a demountable metal partition presenting improved structural features over the metal partition shown in iohnson Patent No. 2,360,500.

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 sections. 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. Spaced horizontally extending spacing channels present the side flanges thereof in abutting contact against the sound deadening layer of the panel facing sheets, the space between the spacing channels being filled with sound deadening packing. The spacing channels within the panel unit are provided with spaced tongues extending from each end thereof inserted into conformed slits cut in the framing uprights. A stretcher stud is threaded into one end of each spacing channel with the head portion thereof extending through the adjacent framing upright permitting the studs to be conveniently manipulated to tension the facing sheets and remove waves and irregularities from the surfaces thereof.

The glazed panel units are also constructed from identical framing uprights having sound insulated metal facing sheets extending to any convenient height desired. A sash frame is separately fabricated to receive either one or two panes of glass and then telescoped between the upper portions of the framing uprights to snugly seat against the upper edges of the applied facing sheets to form a smooth and flush joint therewith. The glass retaining molding comprises a fixed molding strip secured to and forming a part of the sash frame, the glass being retained in position by removable molding strips.

Supporting and levelling devices are provided which are secured to the building floor along the partition run to insure accurate alignment and levelling of the partition sections as erected thereon. Only three types of connecting clips are required to rigidly connect the panel and door frame units together under substantially all partition run conditions. The straight run connecting clips have hook portions removably insertable into the slots formed in the framing uprights to connect the adjacent panel and door frame units in straight run alignment. The inner corner connecting clips have hook portions insertable into the adjacent clip receiving slots when adjacent units are arranged in angular relationship. The outer corner connecting clips also have hook portions for insertion into the adjacent paired clip receiving slots at the outer corner of the angularly arranged panel units. Removable post caps span the space between adjacent uprights and are designed to resiliently engage rolled edge portions formed on the connecting clips.

The cornice assembly comprises a cornice frame which extends continuously over the erected panel sections, formed from paired channel shaped members arranged 2,766,855 Patented Oct. 16, 1956 back to back providing a rigid I-beam construction presenti'ng two-compartment Wiring raceways. The wiring raceways are enclosed on each side of the partition by continuous cornice covers which snap into removable engagement with the outwardly extending flanges of the cornice frame permitting convenient access at all times to the wiring and conduits contained therein; The cornice frame is detachably secured to the unit uprights by fixed lugs and removable keys.

As a further feature, this improved partition incorpo rates a floating base assembly comprising a floating base frame positioned between the lower projecting ends of the framing uprights of each panel unit. Each floating base frame may be economically constructed from a pair of generally channel shaped sheet metal members arranged back to back to provide a two compartment raceway there in which align with cableway holes cut in the lower end extensions of the framing uprights, thereby permitting wires and cables to be strung the full length of the partition run. The outwardly extending flanges of each base frame terminate in upwardly extending legs to which baseboard members may be removably secured. The baseboard members may be economically fabricated from sheet metal strip cut in any desired length and are installed on each side of the partition to extend the full length of the partition run, the terminal ends of the baseboards adjacent the door frame being covered by removable plinth blocks. The baseboard members may be re moved and replaced after installation, providing convenient access to the wiring and conduits contained in the base frame sections. This improved base assembly conceals floor irregularities, provides an attractive trim for the lower ends of the partition sections, and permits insertion of floor carpeting under the lower edge thereof.

The Wall filler assembly comprises a framing upright secured to the adjacent framing upright of the adjacent panel or door frame unit by straight run connecting clips, and a wall trim channel removably secured to the adjacent Wall of the building, the space therebetween being covered by separate facing sheets having insulating felt secured to the inside surfaces thereof. The ceiling filler assembly comprises parts which are fabricated in the shop for field erection to extend from the cornice assembly to the ceiling. The cornice filler framing comprises paired channel shaped verticals extending through preformed holes in the top and bottom flanges of the cornice frame and into the space between the adjacent framing uprights of adjacent pat-ti tion sections. A ceiling trim channel containing a spacing channel is removably secured to the ceiling, and a corresponding spacing channel is secured to the upper flanges of the cornice frame. Metal facing sheets are applied to the thus erected framing and the space between the ceiling filler facing sheets may be filled with sound deadening packing as the facing sheets are erected in the field. i

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

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 ceiling Z 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 normally encountered 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 I which may be interchangeably arranged as desired. The partition units are shown capped by a cornice assembly E with a ceiling filler assembly H mounted on the cornice assembly and extending to the ceiling Z. A wall filter assembly G is shown in abutment against the permanent wall Y of the building, filling the space between the wall Y and adjacent glazed panel section A.

Partition unit supporting and leveling devices B, each comprising a floor block having flat leveling shims 65 capped by an aligning shim 65', are secured to the floor along the partition run and positioned between the adjacent vertical edges of adjacent partition sections 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 straight run connecting clips C normally covered by removable 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 C, and the outer corners thereof are detachably secured together in rigid assembly by outer corner connecting clips C normally concealed from view by a corner pilaster cap F which is resiliently but removably secured to the attached outer corner connecting clips C".

The floating base assembly F extends along the build ing floor with its base frames 110 contained between the framing uprights of the panel units, the base frames 119 being normally concealed by removable baseboards 124 extending along each side of the partition runs, providing an attractive finishing trim which conceals floor irregularities. A door 171 is shown mounted within the door 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 cor-- nice frame 94 of I-beam formation which caps the erected. partition sections and greatly strengthens the erected partition. The cornice frame 94, providing a two compart-- ment wiring raceway, is capped on each side thereof by removable cornice covers 106.

By removing the cornice covers from the cornice frame: 94, the baseboards 124 from the floating base frames 11%, and the pilaster caps D and D' from the partition section connecting clips C and C", complete access may be had for the installation or repair of conduits and ca bles leading to outlets installed at any desired location on the erected partition.

Panel units The interchangeable flush panel units A, presenting 6 substantially flush facing surfaces throughout their height and constructed more particularly as illustrated in Figs. 2 to 12 inclusive and Figs. 22, 23 and 24, comprise ver tical 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 8 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 and extending substantially parallel to the main web 2, the intermediate webs 4 each terminating in an outturned outer leg 5 spaced from and extending substantially parallel to the inner legs 3.

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 a 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 Figs. 2, 5 and 8 to 11 inclusive. A pair of struck out tongue elements 19 extend from each end of the spacing channel and are designed to be inserted into corresponding tongue receiving slits 7 cut through the intermediate webs 4 of the framing uprights 1 to be thereby supported. After assembly of the panel unit has been completed, the inserted tongue elements 19 may be bent or twisted to secure the spacing channel 16 to the framing uprights 1.

Each spacing channel 16 may be reinforced by forming a longitudinal extending reinforcing rib 20 in the web portion 17 thereof. One end of each spacing channel is formed to present a pair of alternate spanners 21 which are bent downwardly into arcuate shape and a pair of intermediate spanners 21' which are bent upwardly into arcuate shape. The companion spanners 21 and 21' are internally threaded and are shaped to provide a threaded hole of uniform diameter designed to receive the threaded shank portion 24 of a stretcher stud 23 as shown in Fig. 12. A clearance slot 22 separates the adjacent end of the reinforcing rib 2! from the threaded spanners to provide room for the inserted end of the threaded shank portion 24 of the stretcher stud 23.

The stretcher stud 23 presents a flared base portion 25 of substantial area designed to snugly seat against the inside face of the main web 2 of the adjacent framing upright 1 as shown in Fig. 2, with the round neck portion 26 thereof extending through a corresponding hole 6 in the adjacent framing upright 1 so that the hole 6 provides a bearing therefor. The rounded neck portion 26 terminates in a rectangular head portion 26' to which a wrench may be applied to manipulate the spreader stud 23.

A wall forming panel sheet 10 is mounted on each side of the framing formed by are vertical uprights 1 and the horizontal spacing channels 16. As shown in Fig. 6, the facing sheet 10 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 squared edge 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. 6. 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 isthen 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 5 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 headportions 26' of the spreader studs 23. projecting through the holes din 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 10, 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 end portion of each framing .uprightl extends somewhat below the lower edges of the facing sheets 10 to provide room for wiring and conduits therebelow which may be 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 28' to thereby detachably secure the cornice assembly to the partition units.

Each glazed panel unit A as illustrated in Figs. 13 to 21 inclusive, is constructed from a pair of framing uprights 1 upon which panel forming sheets ltl'are mounted to extend to the desired height. The lower half section of g each glazed panel unit A is constructed similar to the flush panel units A illustrated in Figs. 2 to 12 inclusive and heretofore described, and wherein spacing channels 16 areemployed as shown in Fig. 10 having tongue elements 19 inserted into corresponding slits 7 formed in the framing uprights'l, spreader'studs 23 being associ-' ated with eac h spacing channel 16 whereby the desired tensionmay 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. 13, 14 and 15 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 39 which comprises a pair of vertical framing members 31 and a pair of horizontal framing members 36. Each vertical framing member 31 as shown in Figs. 14, 16, 17 and 19 comprises a web portion 32 terminating in outturned flange portions 33. Each outturned 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 of the sash fuame.

tion until the squared edge portions 39 thereof are brought into seating engagement with the squared edge portions.

Mouldings are provided to removably retain a glass pane 41 within the sash frame, 30 as shown in Figs. 16,

17 and 19. 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 memher. 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 -51} associated therewith. The adjacent ends of the fixed moulding strips 42 are beveled and interfitted to provide a finished moulding frame.

Each removable moulding strip is constructed to be applied to the opposite face of the installed window pane 41 and to 'removab'ly interlock with the offset flange 1 portion 47 of the fixed moulding strip 42. Each removfixed moulding strip 42, with the foot portion 52 of the removable moulding strip seating against the base portion 43 of the fixed moul-ding 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 in inserted in the grove formed by the wall portions 44 and 51 of the moulding strips to secure the glass pane 41 lll'POS'll'lOTl.

The fully assembled sash fname 30, with the window pane 41 installed and retained therein by the moulding frames 42 and 5B, 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 The sash frame is pushed into posi- 13 of the adjacent panel sheets 10'. As thus assembled the offset flange portions 38 of the lower framing memmembers 31. Each horizontal framing member 36 presents a web portions37 and flange portions 38 having outwardly offset facing portions 33. Each offset facing portion 38' has an and extension 38 projecting from each end thereof whichoverlap and are welded to the adjacent ends of the flange portions 33 of the vertical framing members 31 as indicated in Fig. 17. Each outwardly offset flange portion 33 terminates in a squared edge portion 39 and an inwardly rebent lip portion 40. When the assembled sash frame has been telescoped into final position between the spaced fnaming uprights 1, the squared edge portions 39 of the lower horizontal framing member 36,will snugly seat against the squared edge portions 13 of the adjacent panel sheets llltherebelow as shown in Fig. 17, with the flared lip portions. 40 of the horizontal framing member 36 hes-ting within the up turned lip' portions 14 'ofthe anjacenepanersheets.
