' BEDSTEAD LQCK AND STIFFENER.

Application filed Enne 7, 1920, Serial BT01386568.

To allV iodo/m` t indy/concern.' l

Be it known that we, HENRY J; Honwroia and Eenrum) STEINMAN, both residing at Chicago, `Cook County, illinois, and both citizens ottheUnit-ed States, have i ented f in new and iisei'iil Inii'irovements in a Bedstead Lock aiidiititieiier; and` we do hereby declare tion, such as will enableothers skilled in the art to which it apperta-ins to make and usethe same.

l *Our inventionreia'tes to metal bedsteads and in its general obi'ects includes the sti'iieii-- ing' ot bedstead ends and the providing,v oi simple means constructed vchieiy of sheet metal for affording the operative connections between various parts ot the bedstead at the corner posts.

in one aspect, oiirinventioii aims to provide a socket constructed chietlyo't sheet metal and adapted to be secured to a tubular bed' postwithout employing screws or bolts, to provide sockets of this class which wiii notrock on the posts to which they are cured and touse the sockets attlie same end of the bedstead as means tor connecting.;` a or this last named purpose, our invention aims to construct these sockets so that a stiiiener may directly t0 the same and preferably so that both webs of an anglesection stitener may be secured directly to dii'terent parts ofsuch a socket.

i/Vliiieour invention `in lits above named aspects may be employed with various bed .spring` or bed-bottom arrangements it is particularly suited tor use with bed coii'-A structions in which the bedstead eiidscoopcrate with the side rails iii forming` a rigid trame and in which stretched in a. separate traine supported b'v the side rails. vFor siichbeds, our invention aims to provide simple,` strong and effective side rail tipsV adapted' to interlock with sockets of the type above mentioned,so as to afford a simple and inexpensive bedstead lock. Still further and also more detailed objects will appear v.from `the following specification and from the accompanyingl drawings, in whichhf i i Figui isan' 'enlarged and fragmentary vertical section through a bed post and through adjacent parts embodying our invention, taken centrally ot the post and `longitudinally ot' the side rail ot the bedstead.

the following to be a iiili,` clear, and exact description ot the inventhe bed-bottom is Renewed December 26, 1922.

Fig. 2 is a plan view of the same bedstead corner, taken from the top o1- Fig. l. Fig. 3 is a perspective view of the hook member or terminal on one end of a side rail of the bedstead.

Fig. S is ii plan view showing' the `stiitener interposed between the sockets carried by the posts on a bedstead end.

Fig. 9 is a plan View of a simplified form ot socket adapted for use on a round post and without the stiii'ener.. Y

ln accomplishing` the purposes of our invention after the manner illustrated in the drawings, we first secure to each post of the bedstead a socket member inciuding' a transverse pin, then `mount a hook member upon` the adjacent end oi the side rail ot the bedstead and interlock the hooks ot' this meinber with the transverse pin on thesocket member. Both of these members are preferably constructed of steel and preferably designed so that they can be manufactured chieiy by punch press operations, thereby reduciine` their costaud insuring iiiiit'oririity oi"l the parts.

To use our invention in coi'inection with bedsteads having square sectioned tubular corner posts, we first punch an aperture .1. in each ci the pests l* along` the tace directeij'l towards the side rail oi" the bedstead. riheii we provide af corresponding aiiierture 3 iii the back and rests squarely against the post 2 and which back has a pair-,oiE vertical webs 6 er;-

tending from its opposite edges towards the `opposite end of the bedstead.` These webs et ot the socket. which back is fiat y vvthe saine end ofthe shank of the key further into `the post,

thereby drawing the enlarged heads 9 of the key against the outerz face of the back e ot the socket so as to secure this socket firnily -to the post with vthe cross-i-baiin a iixed position predetermined by the location of the perforation l in the post.

To secure `the d -lsired rigidity in the corre! spending' end of the bedstead, `which inay be ithcr the head ciid or the 'foot end, We d-esiiablyalso connect the two socketson bedstead by a stiffeiier 9:5., so as to avoid the need of castings or other auxiliary fast-.enings for this purpose. lith thisqin niind, We desirably forni the blankfor Ithesocket after the nianner `of Fig. G, so as to include projecting lug` 1() at the top of the web (i which inay be` directed toward the conipanion socket when the partsare formed up. Then We bend this Wing 10 at right ane'les to the adjacent web as shown in Fig. el., so as to extend horizoiitally when the socket is in position. Vle also "desirably punch another Wing 11 from the saine web 6 of the blank forthe `socket and bend this toward the companion socket so that it will extend vertically and at right angles to this web. an angle steel stiifener 11 after the inanner shown in Fig.

25to the lugs 10 and 5, thereby affording` a rigid `connection lbetween the companion sockets at the saine end of the bed, so that these sockets forni` the nie-ans of connecting` the stiffener 25 to that end of i thelbedstead.

In.. punching the blank of Fig. 6 for the 1 forked sheet inetal part of the socket, we

Vdesirably niake thc `pei'foration 3 of the 4saine size and rectangular shap I vtionl in the post to which the socket iste be as the perforasecured,.thus pern'iitting the wedge #t to expand the key until its sides engage the side walls of the perforations in both parts. Thus arranged, the key itself will tend to keep the socket from rotating about the latter an axis, but in practice the strains lmay be too great for the user to depend on the key to preventan unsightly tilting4 or rocking of the socket on the post. ille therefore desirably equip each socket `with auxiliary means for preventing` such tilting.,

as by'providing each end of the blank of Fig. 6 with Wings 12 and 13 adapted to be `bent lin the opp'ositedirection from the Webs G and so spaced as to engage opposite sides of the adjacent post. Thus constructed, it will be evident from Fig. l that thev sheet metal part of our socket is substantially `Then We rivet or bolt ii-sliaped in its plan View (except for the wings to which the stifl'ener is fastened), with the upper part of the fi fornied by tivo pairs of `lugs spaced vertically along the adjacent post when the socket is in position. These pairs of lugs therefore straddle Widely spaced part-s of the'npost and securely hold the socket against rocking, although reeniiring` no further fastening eleinents of any kind for this purpose.` l

To interlock the side railsof the bedstead with such sockets', We equip eachv end of each rail with a hook ineniber or end piece designed to hook over the horizontal cross-bar 5 on an adjacent socket. lWe also prefer ably inake the extreme `hook portions of such a length that the tip of with which it is used, thereby securing the iirinly wedged interlocking which is incre fully `described "in our copending applica tion for a U.` S. patent on a 'bedstead lock,

sulting tube, thereby insuring arigid unit` ing of these parts7` While the securing ofthe `ends 26 to each other prevents any strain from opening' sides apart. i.

However, While We have heretofore .described our invention in a desirable e1nbodinient adapted for use With bedsteads having square sectioned hollow postsiand angle sectioned side rails, We do not Wish to be liinited to the details of the constructionand arrangement thus disclosed. i 'Obviously'.va iiious addi tions7 oinissi ons `an d other ciian'ges might be inade Without departing Ifrein the spi rit ofou r'in ventioii or from 'the appended claims. For example, the saine arrangement of' connecting ineiiibers carried byV the side rails oi' the bedstead may be used in connecn tion withl round posts, and the :latler'need not necessarily have the sockets on the `same connected by stilfeners. Thus, JFig. 9 shows a socket having a `back curved to lit a round post andv designed. for use Withoutany such stiffener as that shoyvninFigs. and 8.

c `We claim as our` invention:

1. In a bedsteadfside` rails havin@` end nienibers formed of nietal pieces of tubular yout the tube or spreading its rectangular cross-section the sides of `which` are formed With hooks and 4thebottoins of Which yare forined ofthe ends of the pieces,

said ends being overlapped and secured tov ,the hook lin i each case engages the back et of the socket 2. In a bedstead, a pair-of posts, a socket for each post having a back and having side wings between its top and bottom extending outwardly from the back, the ends of the sides of the back being bent outwardly in a direction opposite to that in which the wings extend to form an upper and a lower pair of llanges which engage the post, a cross-pin borne by the wings, the inner wing of each socket having' an extension at its top extending outwardly in a horizontal plane and having a struck-out member eX- tending vertically and underlying the eX- tension, and an angle-bar secured to the ex tensions and struck-out members respectively of the sockets.

3. In a bedstead, a corner post, a socket member having a back secured to the post and having side wings, a eross-pin secured to the wings, and a side rail having a tubular end member of rectangular cross-section the sides of which member are formed with hooks and the bottom of which is 'l'ormed of the ends of the member overlapped and secured to each other, the edges ot said overlapped ends and the edges oit the sides and top of the end member being in the same plane whereby when the hooks are engaged with the cross-pin said edges will engage and be braced by the back of the socket member and the sides ont the tubular member will engage the side wings oi' the socket member.

l. In a bedstead, a corner post, a socket member having' a back and side wings between the top and bottom of the back, the back having an upper and a lower pair ot flanges located respectively above and below the side wings and engaged with the post to brace the socket member, a cross-pin connected to the wings, and a side rail having a tubular end member of rectangular cross-section the sides of which member are formed with hooks and 'the bottom of which is formed of the ends ot the member overlapped and secured to each other, the edges ot said overlapped ends and the edges ot the sides and top of the end member being in the saine plane whereby when the hooks are engaged with the cross-pin said edges will engage and be braced by the back o'i` the socket member and the sides o'll the tnbular member will engage the side wings ot the socket member.
