METAL STUDDING SYSTEM Filed July 26, 1958 3 Sheets-Sheet 2 Patented Oct. 15, 1940 v i, UNITED STATES PATENT OFFICE 10 Claims.
This invention relates to structural building elements,'and more particularly to novel means for facilitating the erection of a fireproof studding system. Steel studding usually consists of fabricated beams made up of comparatively light metalparts which must be anchored to the belling and floor, frequently using track sections at one or both points.
According to the present invention, it is proposed to provide means associated with each stud which will permit of its being placed between the ceiling and fioor tracks in an intially oblique po sition. and thentwisted or turned at right angles to the tracks to become. automatically locked in place. That isto say, aspecial object of the inventionis to provide novel means associated with the opposite ends of the stud for accomplishing an automatic interlock with the tracks, thereby expediting erection and efiectingsaving in time andlaborh' A furtherobject of the invention is to provide a novel form of adjustable shoe and aslotted clip which may be used respectively at the top and bottom ofthe stud, or vice versa, and which in either case may become interlocked with the track sections by twisting or rotating the stud engaged therewith from an initial oblique position to an ultimate transverse position, namely, the position that the stud is to occupy in the completed structure. In that connection it willjbe also understood that the adjustable shoemay be usedat opposite ends of the stud, or, on the other hand, the slotted anchoring clips may be used at opposite ends of the stud since in both cases they maybe interlocked with the tracks by twisting or turning. In some cases the slotted anchoring clips maybe incorporated as a fixed part of the stud atthe time the latter is fabricated, and when this form of clip interlocking means is used, the.
4,0 studding may be made in sections and connected by splicing sleeves which telescopically fit over the chord members of the stud to permit relative adjustment of the stud sections to suit difierent partition heights. As further illustrating the wide application ofthe novel feature of twisting or turning the stud into final position, the inven tion' also contemplates providing the clip directly with arms in the nature of the splicing sleeves so that the clipxmay be adjustable on the stud in same manner as the shoe. In that connection, however; it may be pointed out that when the clip is provided with arms of this type, it is not necessary towirethe arms to the chords or H flanges of 'fthistud because the sleeve like arms telescopically fit over the said chords or flanges.
With the aboveand other objects in view which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and ar rangementsof parts hereinafter more fully described, illustrated and claimed.

According to the embodiment of the invention shown in thedrawings, the ceiling track is designated generally as A, the fioor track 3, the studdingC' and the adjustable'top'shoe for the stud is identified generally as D. At the bottom of the stud there is provided a slotted anchor clip E, which, although useful in connecting the bottom of the stud with the floor track B in the particular combination shown in Figure 1, may also be used at the upper end of the stud for connecting the top thereof with a ceiling track A, as will later appear.
In connection with the shoe D and clip E, a distinctive characteristic in common is that both of these elementspermit of first applying the same, including the stud, at anoblique angle to the ceiling and floor tracks and within the channel provided therein, and then from this initial position, the entire stud may be turned or twisted into right angular relation with both tracks whereupon they automatically become locked in anchored or set position. I
Referring first to the ceiling and floor tracks A and B it may be pointed out that these elements are of channel cross-section and in the embodiment shown preferably consist of opposite flanges or chord members, for example, the angle irons I-I, connected by transverse web straps 2. The stud C may be of the same general construction as the ceiling and fioor tracks, that is, the stud may .be of'channel formation just described, or it may be of substantially I-beam formation in cross section as shown in the drawings. Ineither event the stud C comprises the opposite flangeportions or chords 33 connected by a transverse web member or members 4, the ends of the latter being welded or otherwise secured to the chord members whether they comprise a single 'L-shaped channel or two L-shaped channels arranged back to back.
In practice, the ceiling track A may besecured to' the joist in any suitable manner with the channel portion thereof facing downwardly toward the floor track B. The said floor track in turn may be secured to the floor with its channel facing upwardly. 'When th'e'two tracks are secured in their relative and vertically aligned positions, the novel adjustable shoe D may be made to interlock withthe' ceiling track A in a manner now to be described. I
The said shoe D is preferably of substantially U-shaped formation, although in use at the top of the stud it assumes the position of an inverted U. Therefore, the said shoe D comprises the arms 55 which may be of channel formation and slidably or adjustably embrace the chords 3-3 of the stud, the said arms being connected by a stepped or shouldered transverse web portion 6. That is tosay, the web portion 6-includes a substantially straight or flat intermediate portion I while the ends thereof are bent downwardly as indicated at 8 and thence outwardly as indicated at 9 where they connect with the arms 5. This formation (I8) permits the shoe to fit within the channel provided by the ceiling track A and enables the shoe to be inserted into the track from beneath or below the same. The portion I of the shoe is provided with suitable keeper means in the form ofthe struck up projections or oppositely directed lugs III which form keeper openings or slots I I to receive the horizontal legs of the channel members I of the ceiling track. In'other Words, the projections IilI are so made that the portions thereof which connect with the part 'I are spaced apart a less distance'than the'space between the adjacent edges of the horizontal flanges of the angle members II which constitute inwardly facing abutments on the track. On the other hand, the
outer portions of the struck out projections or lugs I0I0 are long enough to overlie the upper edges of the horizontal legs of the angles I-I when the shoe is in final position. In order to apply the shoe to the selected track it will thus be apparent that the shoe must be initially or originally held at an oblique angle to the longitudinal axis of the track and the lugs II] must be inserted within the space between the edges of the horizontal legs of the channels I. Then by twisting or turning the entire shoe until the latter is disposed at right angles to the ceiling track, the lugs Ii] become interlocked with the track A. The arms -5 may be sprung apart when forced over the stud and to insure permanent engagement therewith, after adjustment, they may be secured to said chords by twisting wire about them or by nails or other fastenings driven through the slots in the arms and into the space between the chord angles.
It will, of course, be understood that the shoe D may be applied to the track A in the manner above described before the stud C is inserted in the legs 55 thereof, or on the other hand, according to the usual custom, the shoe D may be first applied to the' end of the stud and the entire assembly applied and then rotated to flnal'position,
The anchor clip E at the bottom of the stud is preferably of substantially L-shaped cross-section and thus includes the flanges I2 "and I3. The flange I2, according to one form of the invention has its end portions welded or otherwise secured to the stud, and the opposite edges of the flange I2 near the flange I3 are slotted or cut away as indicated at I4 to provide keeper means in the form of recesses or slots to receive the horizontal legs of the channelmembers I of the floor track B. In practice, the clip E may be interlocked or connected with the floor track B in the same way as the shoe D. That is to say. the stud carrying a clip E may be first obliquely disposed within the floor track B with the slots I4 opposite the horizontal legs of the channels'l and then the stud may be turned or twisted until it moves into a position at right angles to the track. In this way the stud becomes automatically locked with the floor track B.
From the foregoing it will be apparentthat when studs with plain ends are used the adjustable shoe D may be applied to both the upper and lower ends of the stud, or, on the other hand, the opposite ends of the stud may be both equipped at the time of making with the slotted anchor .clips E. In other words, both ends of the studs may be equipped with similar types of interlocking means or with different forms of interlocking means as shown in the drawings. In'either case the function and result are the same, namely, that by twisting or turning the stud relative to the track in applying the same the stud becomes interlocked with the track. The advantage of using shoes D at both ends of the stud, or a shoe at one end and an anchoring clip at the other, is to render the stud of adjustable length, as, for example, by sliding the arms along the chords of the stud to the selected point before securing the arms to the chords.
Short sections of studs C and C may be made up with the slotted anchor clips E at one end and in this case, the stud sections maybe connected and adjusted as to length by shifting them in the splicing sleeves F. That is to say, where the slotted anchor clips E are built into the end of a stud section, at the time of manufacture, it is .members of the stud.
preferred to connect; them bylthe splicing, shoes F which telescopically fit overtheoppositelchord The splicing sleeves F; ,areipreferablymade of suitable gauge metal including, i a body portion l having its side portions I] folded inwardlytoward each other and terminating inthe offsetsubstantially parallel flangeportionsa'l'8. The splicing sleeves F are, of course, .opeinatthe ,ends and, are intended to conform in cross-section to the shape of the chords ofthe .stud.- The cross-sectional formation of the, splicing sleeves above referred to is primarily intended tocooperateiwith Jchords made to give the studa substantially I -rbeam cross section. However; it willpofq course,- be. understood thatii the chords of thestudareof angle or L-shaped formation, it is within the scopeo'ttha invention toichangethe cross-sectional shape of the splicing sleeve Faccordinglylg l Where maximum extensibility of the; studding is requiredthe arrangement shown inFigure 6 may be resorted to; Accordingtothis modificae tion the stud sections C and C? are not only: conneoted by the. splicing sleeves I; but an end:ofone of the stud sections may be fitted with-an adjustableshoe D offlthe type previously described, including the track interlocking means, for securing the stud to. the track. The splicing sleeves F may be secured to the chords of thestudin any suit-. able manner toprevent shifting. thereof. That is to say, they may be wired to the chords or a nail or other fastening may be used to wedge. the sleeve to the chord by; placing the fastening between a portion, of the sleeve and'its embraced chord, or where the chord consists of angles back to back, the" fastening maybe 'wedgedin the space be tween the angles of the chord by. placing the fastening at the lower end of the sleeve or even driving. it through. the body 16 of theesleeve and into the space betweenthe angles of the chord.
Where the slotted anchor clips E'are used, it is desirable to bend the flanges of the chords slightly inwardly by a hammer blow or the like as indicated at 3a so that the twisting of the chord in the channel of thetrack may be facilitated. 'It will, of course, be understood that since the angle members I of the track sections are made of metal they are inherently resilient, and, during the twisting of the stud in final position the angles will yield sufiiciently to permit the stud to move from its initial oblique position to the final transverse position.
Figures 8 and 9 of the drawings illustrate the embodiment of the anchor clip to perform the same function as the adjustable stud. That is to say, the anchor clip E including the flanges [2a and lea and having the side slots Ma has the flange portion In spot welded or otherwise rigidly secured to arm members F" which are in the nature of sleeves for engaging over the chords or flanges of the stud C The arms F include a body portion 20 having the side portions 2| thereof folded inwardly and then bent at right angles as indicated at 22 to provide attaching flanges. These flanges embrace the opposite sides of the flange E211 and maybe spot welded or otherwise secured thereto. If desired, the body 2%] may be slotted as indicatedat 23 to bring the edge of the flange lta flush with the outer surface of the body. It will, of course, be understood that the anchor clip E is provided with two arms F so that in effect the completed unit is of inverted U-shape formation. The arms F have a sliding telescopic engagement with the chords or flanges of the stud justedrelative to the stud. Because of thetele' scopic fit between the arms F and the chords or flanges of the stud, and since the arms F are connected to the clip, it is unnecessary to wire or otherwise] fasten the arms to the stud inasmuch as the telescopic engagement between the parts prevents spreading or shifting of the arms F.
Figures 11 and ,12 of the drawings illustrate a further modified form; of anchor clip E which may be used inconjunction with a stud C of channel formation, that is, a rolled channel as distinguished from, a fabricated channel. The
anchor clip lil consists of ,a body portion 24 having side flanges 25 for slidably embracing the flanges 26 of the stud C The upper end of the body 2G is bent at right angles as indicated at 21 and has its, opposite edge portions formed into lugs 23 which overlie the inwardly extending notches or recesses 29 intended to receive opposite abutment portions of the track A In this construction it will be apparent that the anchor clip E is made of one-piece and is so formed that it may slidably engage the stud C to be adjustable thereon. The manner of applying the form of anchor clip E to the track is the same as that employed in connection with other forms of the clip or the adjustable shoe, that is, the desired interlock is obtained by turning or twisting the anchor clip from an oblique to a right angular position relative to y the track.
Figure illustrates a further modification of g the combined anchor clip and sleeve construction wherein the unit is made of inverted V-shape and in one piece. That is to say, the anchor clip portion E is formed integrally with the side sleeves F The anchor clip E has the web portion 33 formed with rounded corners 3| to easily fit within the track and the body of the web is cut away I at the opposite edges and displaced or struckup transversely to provide the slotted portions 32 and the track interlocking extensions 33. The sleeves or arms F are of such cross sectional shape as to slidably and telescopically embrace the chords of the stud.
From the foregoing, it will be apparent that the present invention provides a fabricated metallic studding system which admits of a wide variation of application in actual use because of its adjustability, and also because of the facility with which the studs may be interlocked with the tracks at the time of installation. Moreover, the present system enables the manufacturer of the stud to make the studding sections in more or less standardized lengths and carry them in stock, while at the same time enabling them to be quickly adapted to any given specification with the range 3f adjustability provided by the novel construcion.
