30 Claims.

This invention relates to framing structures, especially those suitable to production in metal by rolling and similar operations, and particularly of that type illustrated in my copending application, Ser. No. 374,568, filed January 15,

It is an important aim of the invention to perfect such framing to use in providing a mounting for shelving and other structural and utilitarian features of buildings.

It is a particularly important aim of the present application and invention to, at the same time, coordinate the structural frame elements with shelf devices to the end that at the same time that the frame is erected, it provides means by which shelving may be put in place thereon, without addition of parts to the frame or attachment of supports to receive the shelving.

A further important aim of the invention is to present a construction in the essential frame parts,,enabling them to be produced at low cost from stock rolled. materials that are available commercially, as well as to enable their production as integral stock forms, if desired.

It is contemplated that the invention may be utilized for supporting other elements other than shelves by extension or adaptation 'of the invention herein disclosed.

It is an important aim of the invention to evolve structural frame elements which will enable the placing of shelving or the like and other articles in releasable and adjustable relation to the structural elements. It is also an important aim of the invention to coordinate the structural post'or stud member in its form to shelf or other elements mounted on the post or stud member to the end that a highly rigid structure will be provided in which load stresses will be most effectively opposed with the use of a minimum of material.

Another aim of the invention is to evolve such post and stud structural members in metal with parts so arranged as to facilitate welding with speed and economy. A further aim is to provide a construction of post and stud elements and shelf or other mounting device in which there will be a secure coengagement of the parts under loads to prevent accidental disengagement, while yet leaving them rapidly detachable .when desired. It is also an aim to attain the foregoing objects while at the same time enabling sectional shelves to be mounted so that the individual sections may be independently adjusted as to height.

Additional objects, advantages and features of invention reside in the construction, arrangement and combination of parts involved n tne embodiment of the invention, as hereinafter dis-= a with at opposite sides, independently adjustable and removable.

Figure 46 is'a further development of a similar locking device, showing a continuous web in the stud element, requiring no apertures for insertion of the shelf arms.

Figure 47 shows the development in which a also formed of fiat metal stock of suitable weight for the purpose, their body portions attached to the shelf being arranged in vertical planes nor mal to the plane of the shelf in each instance, and in the present instance, shown as separate pieces welded or otherwise attached to the under sides of the shelves. The arms 6 extend rearwardly of the shelves, there being one arm located at each end of the shelf, in the present instance, and as many more intermediately of the length of the shelf as may be required for proper support of the shelf, and to aline with a number of stud or frame elements I in the structure upon which the shelving is to be mounted. In the present instance, the shelves are indicated as mounted on both sides of the member I, their arms 6 being projected a distance from the shelves sufficient to enter through the openings 4 while the arms lie in vertical plane close beside or parallel to the flanges 2. At their extremities,

the arms 6 are provided with knobs or nibs 8,-extended upwardly, and arranged to engage against the side of the web element 3 thereabove when the arm is inserted through an opening 4, so as to prevent withdrawal of the arms 6 when in horizontal position or other normal supporting position for the shelf 1, or other article which may be carried upon the arms 6. Also, the ends of the arms from a distance below the top of the nibs 8 are bevelled or inclined longitudinally in-' ward toward the lower part, as indicated at 9. This will facilitate introduction of the projecting rear ends In of the arms 6, so as'to properly engage beyond the web portions, as shown in Figure 1, without requiring any great inclination oi the shelf 1 in order for the nibs 8 to pass undez the upper web parts. In addition, the projecting portions Ill may have formed orsecured On their lower edges shoulder pieces ll, arranged to engage against the lower web piece 3 adjacent the openin through which the arm H1 is inserted,

andtto press againstthe: facerof .this'z-zweb piece, so as to properly sustain the whole arms 6 and i .in.-p1ioper supporting position in relation to .the

shelf 1. The shoulder element H maybe omitted or otherwise formed, if desired, especially if the portion of the armsfit snugly between the upper and lower web pieces 3 thereadjacent, or in case-other rest or seat elements are provided to engage the arms In 'or 6 .a distance outwardly from thexmember-l assisted by the flanged rear edge portionv l2 of .shelf I which checks rearward motion of the shelf.

As illustrated in Figure l, it is shown. how my stud or upright may be utilized as a support for shelving, and at the same time it may comprise a. column supporting other structural features resting upon its upper end, while itslower end may be set upona floor or cthef suitable support.

The support shown may, at. the. same time, be utilized as a part of "a panelling or combined stud and screen or reinforcement support, as. shown in Figure 25, where thereis conventionally shown a wire mesh fabric 1 3, secured to the studat each side and extended. in a common plane therefrom,

at right angles to the arms 6, or parallel to the plied to the first flange, or any usual means for holding a plurality of the web elements in 'position' over the flange and .interposed'screen may be employed, as preferred. After securing of the screen material at one side of the stud unit, the material at the opposite side ma belikewise se cured, completing the stud element proper with the screen material applied. If desired, the stud and screen material may be assembled in a panel form; with the screen material attached only at one side, while at. the opposite side the flange 2 may be attached directly to the web element without interposition of the screen material, and after setting of the-stud in place, in the building structure, the screen material to be attached" maybe laid against the-outer face of the web elements, in the same plane with the material attached previously, but at the opposite side of the stud, and the screen material then welded to the face of the web elements. Or, the flange 2 at the side opposite that to whichthe screen is first attached may be 1eft unattached, until thestud is set in place, at which time the screen material at that side of the stud maybe set in place to come between the web element and the new flange to be attached, after which the flange is set against the screen material in proper position with respect to the web element, and by simple electrical or other welding operation, at the junction ,of the new flange, screen material and web elements, the three parts are secured together in one operation. .In theassemblyof the stud element and screen material in the factory, three parts are likewise secured. together by one welding operation, it'being suflicie-nt to appl-y' welding material .so as to join'the web element and edge of the flange thereadjacent, the fluxed material at the same time fasteningthe wiremesh. By applying the weld at the inner side of the flange, a distance from the-.body-of. the screen material, the extreme'e'dge'portion-only of the: screen material is. fluxed in the "welding-10peratlon, and the; heat of welding is transmitted so rapidly to the flange and web material that the I3. is secured only between one of the attached flangesla'nd respective edges. of web portions 3 1 of. the stud of Figure-l. In this manner, an end support for a partition or screen may be constructed.

-A stud member.:Figure 1 may be produced in corresponding form with different structural elements, .as for instance in Figure 2, where the stud consistsof a stock angle 14, one flange of which is crenelated so as to form slots l5 extending to. the-root of the-crenelated flange and spaced web elements'3', and against the extremities of these crenelles thus formed, the second'flange strip. 2 is Welded, as before indicated, supplemented by the integral flange 2' of the stock angle [4 atoppositeside of stud. In the event that this form of stud is used in a partition, the screen material l3 has one edge portion welded against the outer face. of the crenelated flange portion at the root of the flange, while the oppositely extended mesh material, if ,any, is secured between the second flange 2 and the outer parts of the crenelles, in accordance with the construction of the structure shown in Figure 32. In Figure 27,

the. manner. of using the stud of Figure 2 as an end support fora-partition .reinforcement or screen, is shown, the screen material l3. being se-' cured by weldingonly between the attached flange 2 and the extremities of the web elements 3'.

In Figure 3 there is illustrated a stud of the general form ofthat shown in. Figure 1, but obviating theassembling operations, required for the first device, byutilizing a Z-shaped rolled stock member I6, having flanges 2" extended from opposite sides with an integral webportion 3", and the web portion punched out-to form slots II, the intervals between which provide web members 3' of the same dimensions as those numbered 3 in Figure 1, and as previously described.

The device of Figure 3 may be utilized in the same manneras-describedin connection with the stud-element ofv Figure 1, except that there being no attached flanges on this unit; the mesh material must be welded to the outer faces of the Web members 3" and adjacent the edges of the flange elements 2", at the angles of the stud as shown in Figures 31 and 34 with the mesh materialsecured to opposite sides or one side of stu respectively. i

In Figures 4 and 6, the stud member of the general construction involvedthroughout the application, is,provided with seat plates or brackets I8, consisting of flat metal stool-r trimmed to provide apiece with two edges at right angles to each other,3which. are, set in the angle at the junction of the flange and web elements 3 of the stud in Figure 1, the device being elongated so as to project beyond the flange to which it is attached, and extending in the .same general direction. In the present instance, the plate, is tapered toward its extremity, and if desired,-may be inclined from that extremity downwardly toward its'junction with the web element 3. The arm=6 of, the shelfeiement may rest on the bracket plate l8, as seen .in Figure 6, and be sustained more positively at its normal loaded position. By. the welding of these bracket plates I8, the stud flanges. are stifienedaand: the stud member great- 1y strengthened, as will be appreciated. These bracket plates are preferably alined with the lower edges of the openings 4 in the stud device,

and serve as gusset plates, as before indicated, in

addition to supporting the load on the shelf more effectively.

In Figure 5, there is shown a further development of the bracket device at 19, consisting in this case of a much longer plate than the one l8,

bent on a transverse line midway of the plate to afford a top rest plate 20 on which the arms 6 may lie when engaged with the stud member, as before described, and a downwardly and inwardly extended arm 2|, which serves as a buttress or stay for the outer end of the plate 20. The extremity of the plate 20 at its inner end is welded to the vertical face of the web elements 3, or may rest against or on the top edge of the element 3 and be welded thereto. In addition, it may be secured to the adjacent flange 2, if desired, although this is not necessary. The diagonal stay piece 2 I, however, is welded to the flange 2 under the plate 20. The device I9 is thus substantially V-shaped in longitudinal section, and a duplicate one I9 may be attached to the opposite side of the stud member, in the same manner as first described, and shown in Figure 5.

In Figures 8 and 9, it is shown how'two bracket members corresponding to those I9 of Figure may be formed in one piece, indicated by the character 22. In this case, a strip of flat strip stock, about twice the length of that required for one of the brackets 19, is utilized, and its two end portions bent downwardly and inwardly thereunder, to form in the 'middle'part of the strip a rest plate 23 having diagonal stay ends 24 thereon. This device is introduced through the opening 4" and welded to the flanges 2 of the stud. If desired, the plate 23 may be bent upwardly from its middle in each direction, as shown in Figure 9. As further shown in these figures, the web pieces 3'rnay be of small vertical dimensions and the opening 4' correspondingly larger, the top' edges of these web portions not being required for sustaining the load. In such arrangement, the bracket elements 22 will be supported entirely by the flanges 2 of the stud. In Figure 7, there is illustrated a manner of producing the Z-shaped stud or upright from two simple rolled stock angles, both of which are notched in the same manner as the angle 14 of Figure 2. The angles 25 are both thus formed with interrupted web portions 3' and alternated openings l5. These crenelated flanges are brought together with their uninterrupted flanges 2 extending in opposite directions from opposite sides of the assembly, the base of one flange 2' being located at adjacent the extremities of the projecting web parts 3' of the opposite angle. The two pieces are then secured together by welds between the extremities of the web elements 3 and the bases of the flanges 2 at the outer sides of the latter, the welds being indicated generally by the character 5.

In Figure 10, there is illustrated in cross section a slight modification of the structure of the stud of Figure 1, utilizing similar'parts. In this instance, the transverse web part 26 is formed of pieces similar to those used at 3 in Figure 1, and extend at an oblique angle between the two flanges 21, which correspond to the flanges 2 first described, and are in parallel planes. The device of Figure may have brackets 22 mounted therein, in the manner shown inFigures 8 and 9. In this figure, a plurality of shelves 1 with their arms 6 are shown in place at opposite sides having the portions I0 under the web element 26 as shown. The oblique web 26 presents a graded line to the sides of the oppositely engaged portions III which are thus under the exertion of separating from each other, as .will be readily understood.

Figures 28, 29 and 30 illustrate the utilization of the devices of Figures 4 and 5, in a partition or screen, with the screen material or reinforcement I3 extending from opposite sides of the stud I, and except for the top web pieces 3 shown in Figures 29 and 30, the web pieces 30 therebelow are of greater vertical dimensions than in Figure l, and the stay portion 2| of eaph bracket member I9 is rested against the lower part of the web 30. The manner of engagement of the shelving with these devices, and the manner in which the screen material is attached and secured, are in accordance with the prior description.

Figure 33 illustrates the stud or post element formed as in Figure 2, but with mesh material incorporated at opposite sides. v

Figure 35 illustrates the stud member or upright constructed as in Figure 1, and webbing such as screen material or reinforcing mesh applied after complete assembly of the upright body, the screen material l3 being applied against the major transverse faces of the web members 3.

In Figure 11 there is shown a modification of the device in which flange strips 40 are arranged in parallel planes, but with their proximal edges arranged in parallel planes normal to a medial part of the opposite flanges, and secured together by means of transverse web elements 4|, arranged in pairs in transverse alinement, each one being welded across the edge on one flange, at one end of the web element, while the opposite end of the web element is butted against the intermediate inner surface of the opposite flange 40 and welded thereto. Brackets 22, the same as previously described, may be adjusted between the flanges 40, the brackets being made of flat stiff material of a width to fit snugly between the flanges, to which the edges of the.

brackets are welded, as previously indicated. The web elements .015 each pair are spaced above the flat piece of each of the brackets 22 asuitable distance for coengagement with inserted arm portions ID of shelving, as previously described, so that the nibS 8 may engage outwardly of the far or near web element 4!, as may be preferred.

In Figure 12, the upright unit is formed of two angles 42, arranged with two flanges 43 in parallel planes, spaced apartl to receive one of the brackets I922 therebetween snugly, as shown, and spaced slightly longitudinally of the bracket so that the transverse web piece 44 may be laid in lapped relation against the flanges 45 which extend at right angles to the flanges 43. The web pieces 44 being welded to the angles in that relation so as to hold the angles securely in position, the web piece being spaced above the top plate 20 or 23 of the bracket l9-22 in a proper relation to receive the arm portion of a shelf element thereunder, as will be understood.

In Figure 13, the two angles 45, the same as the angles 42 shown in Figure 12, are arranged at the opposite sides of the bracket 22 snugly thereagainst and welded thereto, so that the inner flanges 41 which are against the bracket 22, have the same relation as the flanges 40 of Figure 11, pairs of transverse Web elements 48 being coengaged between and against the flanges 41 in the isamesmanner'as the-web members-4| are en- 'gagedagainst the flanges 40.

uThei latter. construction is illustrated in plan,'in :Figure l5, wherethe .end members of two setsof nshelvesrare shown engaged upon the uprights, the bills ,8 of the respective arm portions being =1ocated between the web elements of. each pair. .;,Figure 14 illustrates the usesof two channel :members ilin the-same relation as the-flanges rw transverse web pieces 4| arranged inpairs therebetweenand secured as in Figure 11, .the abrackets 1119 or being mounted between the channel membersiunder each pair of webpieces,

,as will'be understood. The use of angle or chaninelmembers, as seen in Figures l2-,15,. adds more istrength toithe units, as will: be. also'understood.

.iIn'Figure 16,.the structure of Figure 111 may Ebe lrepresented, except that thetransverse 'web e1ementsw4la, corresponding to thoseall first described, have their upper edge portions -bent tozwardeach other, and the web elements .in other corresponding constructions may be'likewisebent, iif desired, adding to the rigidity of the relation of i thetwo flange pieces. manner'in which the shelf arms-coact with the =-elements of the uprights.

Figure 17'il1ustrates a iurther method of formingthe transverse connection between two angle 'pieces 50 or other "flange elements, the angle rpieces being arranged in the same relation asdescribed in 'Figure13,-.whi-1e the transverse connection consists of a short'length' of angle piece "cent flanges 52, sothattheanglebetween the =fianges of the piecerEl is'at the upper side extending transversely'between the=fianges 52, and the-lower edgesof the'fianges-cf piece-5| are arranged at a common level extending transversely betweenthe flanges 52. A vbracketzz is shown engaged between the angles-50 spaced-below the transverseipiece fil, so -that shelf arms may have their nibs B engaged under these-edges respectively, while the arms rest upon the brackets.

In Figure 18, there are illustrated two simple flat strip stock flanges 53, arrangedin the same relation as the flanges lll of Figure 11, andbetWeen the lapped portions of 1 the :two, diagonal web-elementsll lb are secured, as connecting mem- -bers between the flanges, their'lower-edges being spaced-sothat armportio-nsJO of the shelves 1 inserted I from respective sides may engage with respective lower -edge-portions of themembers Jib, as illustrated, brackets [9- 22 being incorporated under the membersdlb, in accordance with previous descriptions.

In Figure 19, there is shown anupright sub- :stantially Z-shaped in cross section, formedin one piece, as at It, in'Figure 3, and over each opening 11 atopposite sides ofthe web, spaced apart transverse anchor bars 52 'are'secured against-the flanges 2" andthe web portion 3", the lower edges of the anchor bars stopping short oftheelevelofthe lower edge of the opening 1'1 la=proper distance to receive=the nibsf8 of-arm :portions ill) upon theshelf ,the arm-portions vHlresting upon bracketplates lll, corresponding to those. shown at I8 in Figure '4.

et.- members I 8 locatedvand; secured as heretofore Figure 40 is a cross section showing amanner of building up an equivalent of the general form of stud shown in Figure 38, using plain flat stock bar material throughout. In this case, two angle inner edge portions of the flanges 54, and longitudinally of the angularly arranged flanges, suitable web elements 66 are set between the two L-shaped members in a plane with the screen material, .and suitably secured in position. Figure 40a bracket element l9-22 is indicated formally, the arrangement of which may correspond to that previously described in other forms of corresponding shapes. 7 In Figure 41 two angle elements comprising flanges 64 and 55 as before described, with a sim- .-ilar arrangement of the web mesh material l3 are involved, but in place of the single Web element of Figure 40, two web elements 61 are provided, which are secured edgewis against the flanges 64, and positioned against the flanges 65 at a distance from the mesh material I3, so that a substantial space is formed between the two web units at each pair. These webs Glare thus arranged in pairs, and bracket elements Ill-22 may be mounted between the flanges 65 in such relation as to permit the arms of shelving previously described to be inserted under the web pieces and the arms lowered to rest upon the brackets, as before described, the ends of the arms engaging only under the near web elements 61, as shown, so that twosets of arms may be engaged with each web, Without interfering with those at the opposite side.

In both the devices of Figures 40 and 41, in case the stud unit is to be used at the end of a partition or screen, the pieces 64 and 65 may be omitted at one side, and a common single piece angle stock substituted, of corresponding length, and

similarly secured to the remainder of the unit illustrated.

Y In Figure 42 there is illustrated how the device of Figure 1'? may be utilized centrally of a screen or partition reinforcement and the like, the

screen material l3 being secured against the in- "ner faces of the lateral flanges 68, these flanges being offset from one another slightly, so that the screen material at opposite sides lies in a common plane with the material at the other side.

Figure 43 illustrates the utilization of the stud element of Figure 1, centrally in a partition, or

otherwise, where upper and lower edges of the screen material are secured ina horizontal member, which may be united with the stud elements.

In this case, each stud element is shaped at the ends to receive th angularly disposed flat stock bars 69, as shown at the top, and as shown at the bottom. In the first instance, the prox- 'imal edges of the bars 69' are the elevated edges,

the bars being disposed at approximately an angle of 90 degrees, although this may be varied,

.and sloping down from the junctions on each side of the screen'material l3, which is interposed between the proximal edges and welded at the outer side of the angle, the screen extending downward within the angle at the concave side.

At the bottom of the structure of Figure 43, the reinforcement 10 comprises two similar bars which, however, instead of being sloped from their junctions with the screen material inwardly so that the body of the screen material engages within the angle, are arranged in a reversed relation, the bars sloping downwardly and away from the screen edge, which is engaged between the bars at the apex of the angle and extending from the convex side of the angle, or other side of the angle. The bars 10 may stop at the flanges 2, so as to butt thereagainst, or the flanges 2 may be cut at a' suitable inclination to fit upon the respective bars, and the central web portion either cut away or omitted, to a suitable height, to permit the elevated parts of the bars 10 to be set in place extending continuously across the bottom of the stud. If desired, in order to strengthen the base of the stud, the lowermost web elements ll may be of increased vertical dimension, extending from the raised junction of the bars 10 upward a distance greater than the vertical dimension of the web sections 3, first described.

In Figure 44 there is illustrated a modification of the extremities of the arms of the shelving, and the lower edge portion of the web elements which engage therewith, the parts of the arm portions l0 shown in this figure and corresponding to the nibs 8, first described, being simply V-shaped notches 12, out in the upper edge of simple flat. strip stock, so that the nothing requires to be elevated above the major portion of the arm, and it may be produced from simple base bar stock with less waste of material than would be involved in the production .of the arms Bl0, with nibs 8 thereon. A web portion 13 is illustrated, which may be a member connecting front flanges .14, corresponding to the flanges 2, first described, and others in similar functional positions, and the flanges I4 and webs 13 may be part of an integral Z-shaped stock, or may be produced by the various assembly methods before described. At each opening through the web portion, however, the upper edge'bounding such opening is bevelled on opposite sides, so as to produce a V-shaped edge adapted t fit into the notch 12 of the arm element I0. The stud element may otherwise conform to any of the various constructions before described, the utilizing of bracket supports or other corresponding devices being within the discretion of the user. The ends of the arms ID are preferably bevelled at their lower parts, as at 15, so as to facilitate engagement of the nose portions 16 at the ends of the arms l0" through the openings and under the web elements 13.

In Figure 45, a stud element is illustrated in which openings 'l'l are formed through the web portion 18 of the stud, which otherwise conforms to the general Z-shape, previously disclosed, and may be produced by any of the various assembly operations described, the openings 11 being of somewhat greater height than illustrated in Figure 44, but the arms I0 being approximately the same construction as in Figure 44. On each side of the web 18 in this view, at the upper side of the opening 11, anchor bars 19 are welded against the faces of the web, their lower edge portions extending below the lower edge of the web portion 18 at the opening, and each anchor bar having-a -V-shaped lower edge spaced from the lower side of the opening, or from any bracket device included in the upright, a distance such that when the arm portion I0 is engaged under the bar 19, the lower end of the bar engaged in the notch 12 of the arm the extremity of the arm will stop short of any similar arm which may be engaged with the bar 19 at the opposite side of the stud in a similar manner, and the lower edge of the arm I0 may rest upon the bracket device 88, which may correspond to any of these previously described.

In Figure 46 there is shown a. further improvement utilizing the notched arm ID (in which it is made unnecessary to form openings in the web portion of the stud, and instead, anchor bars 8| are provided, spaced some distance away from the central web portion 82 and welded to the flange at the respective side of the stud element, against which the bar 8| abuts. When the arms III are engaged under the anchor bars 8| having lower V-shaped terminals, and rested upon the bracket elements 83, which may correspond to any of those bracket devices previously described, the extremity of the arms I8 stop short of the web 82 and their notches interlock with the V-shaped terminals to prevent general withdrawal or loose movement of the shelf element carried by the arm.

Figure 47 illustrates the formation of V-shaped anchor edges on the lower parts of such web elements as those illustrated in Figures 1 and 8, the bar 83' serving to coengage with shelf arms projected thereunder from opposite sides of the stud in relative positions of stud and shelf illustrated in Figure 5. r

Figure 48 illustrates a further modification of the anchor bar for use with the type of shelf arm last described, and constituting a simple piece of hard stock, square in cross section, with one of its angles projected downwardly, the bar being located in the upper portion of an opening 84, and welded in place in a suitable way, befitting the type of stud and structure otherwise provided. This device being adapted to use bracket elements, as previously described, where arm portions from opposite sides are shown engaged thereupon.

It is an advantage of the type of arm shown at III in the last described figures'that by the proper location of the diagonal anchor bars such as shown in Figure 21, and the cross piece 5! shown in Figure 17 in proper relation to the brackets l9 or other support means for the shelf arms, no specifically formed stock will be required, and the common angle stock or other bar stock simply cut in proper length for welding in place, may be utilized to coact with the arm elements II) in a proper manner.

In all of the figures, the oppositely extended flanges, as, for instance, indicated by the reference character 2 in Figure 1, are of a width greater than the separating web or Web elements,

in accordance with the aim to oppose load stresses most efiectively with the use of aminmium of material.
