. Tolall tvkom it may concern: g V Be it known that I, HARVEY Fox, a citizen f the United States, residing at Chicago, in the county of Cook and State of Illinois, have-invented certain new and useful Im- .provements in :Beds, of which the following is a specification, reference being had there- I .in to the accompanying drawing.
' ,for metallic beds, and consists of the mat My' invention relates to beds and particularly to corner fastenings or couplings ters hereinafter described and 'then pointed out in the claims.
complete coupling embodying various fea- .tures .of'my invention with clamping plate for securing it to one of the corner posts;
Fig. 2 is a similar view of the post-section of the coupling of Fig. 1;' Fig. 3 is a bottom plan-view of parts of Fig. 3; Fig. 4 is .a
i top perspective .view of the rail-section of the coupling of Fig.1; Fig. 5 is a perspective view -of the parts of Fig. 4 taken from the under side; Fig. 6 is aview of the blank from which the body of the post-section is formed; Fig. .7 is a perspective view of the under side of a blank for a modified form of rail-section head; Fig. 8 is a perspective view of a modified form of post-section;
. Fig. 9 isa top plan view of parts of Fig. 8;
Fig. 10 is a detail side view of the seat shown in Fig. 8; Fig. 11 is a top perspective plate 15 upon the outer face thereof and that they are clamped together and to the post by bolts 17.
The numeral 18- indicates in its entirety a blank out of which the body'of the postsection of the coupling is forn'ied, this blank In the drawings :-'-Figure '1 is a. perspec t'ive view, .parts being in section, showing a.
being cut from a suitable piece of sheet metal, preferably sheet steel, and'then bent to form as shown in the various figures to form a connection bet-Ween the post and side and end rails. Referring particularly to Figs. 1, 2, 3, .and .6, as illustrating thepreferred" form, the top 19- of the blank iscurved at one end as at 20 to fit the curvature of the clamping plate 15, and at its opposite end the top is provided with a curved margmal recessor opening 21. The
side s 22 of the blank are bent on the lines 23 at'right angles to the to and their forward;
ends project beyond t e curved end 20 thereof to form wings 24 which are laterally curved outwardly in the are of'the circle of curvature of the end 20 in order to snugly fitagainst the plate 15 to which they are riveted as at 25through the holes 26. v The inner side of eachpost-section is provided wlth anangular slot- 27' to receive one end of the end-ra l 28 and the top of each section is provided with an opening 29 tore ceive a rivet or lug 30 by which the section and end-rail are connected." The opposite ends of thesides 22 arerecessed or notched as at- 30 to for-m'opposite lugs 31 andshoulders 32. The open end ofthe body of the post-section is provided with a filler piece constituting the seat portion of the joint between the section and its associated rail,
and this filler piece in the form shown in these Figs. 1, 2, and 3 consists of a suitable length of sheet metal of a widthto extend from the lower face of the top 19 to substantially flush with the edges of the sides and is bent into curved form at its middle portion corresponding to thecurvature of the recess 21 to form the concaved curved seat 33, the diameter of the curvature being gradually decreased from top to bottoin of the seat in order to form inwardly beveled or inclined walls. The ends or prolongations of the metal of the filler piece are bent angular-1y outwardly from the-seat toform the sides or faces 34 which extend topointswhere they will register with he outer faces of the sides .22-and are then iebentangularly so that their ends will he against either face of the sides to which they are riveted as at 36. The sides 3411f the strips forming the faces 40, and one end 41 1s riveted at the filler piecesare notchedat 36 atthe angles of the ends-35. to .receivetherear- '\vardl'y projecting"horizontal lugs 31 on the lower corners of the free edges of the sides 5 :22, the sides beingheld in the recesses 30 to ;support the .fillerpieces against vertical displacement. v
-'Ihe s1de 'ra1ls-are of the usual channel "barformatlon, and their top horizontal flanges 37 are provided at each end with a projection havingfan car 38 which corresponds to and tits wlt-lun the curved recess or opening 21 of the head of an" associated post-section. Each end. of each rail is also provided with a'dowhwardl-y beveled or in fclined anchor which corresponds to and .fits.

- In the form shown in Fig.- 7 the'vertical 'webof the rail iS'BXtendd as at 46 in suf-.
ficient, length to be bentaround'to the saime contour as the edge of the projection and ear 38,. following also the line of the end of the web 37 and having its end46 shaped like the end 43 and correspondingly riveted to the web 37.
In the blank shown in Fig. 13 the curved end 200i the top- 19 is provided with 'a lug 47, and the opposite ends of the sides 22 are provided with recessesS, the opening 21 also having a square marginal slot 4:9. The
plate 15 is provided with an opening to receive the lug-.47 which is then headed over,
