Application filed my 8, 1929. Serial No 376,554.
Thisinvention relates to portablefolding cots, and particularly to certain details of construction. The cot comprises hollow steel side "rails, each made in two sections connected by a joint which breaks upwardly meach sleeve having side walls projecting be-- yond the end of the rail section to which it is attached, andthese projecting walls having depending perforated ears which 'are connected together by a hinge pin. The
a projecting side walls of one sleeve are adapted to enter the end of the opposing rail sec tionand rest on the bottom thereof andthe projecting side walls and top wall of the other sleeve are adapted to lit around the ff sleeve of the opposing section when the cot" is set up. Thus, parts of each section overlap parts on the other and prevent any tend-' ency of the joint to sag or break downward-i V ly when the cot is set up and in use. In the I p type of cot to which my improvements are applied, the side rails have folding end pieces which incline upwardly when the cot is set up and a wire fabric is stretched between these end pieces. The tension of the fabric and the weight of the human body upon it tend to force the rail sections toward one an other, and in order to resist the end thrusts of the rail sections and prevent them from" being forced endwise through the sleeves, I
the ends of the sections and form stops to prevent this relative movement. The
tongues also serve to correctly position the sleeves in securing the latter to the rail sec-.
The cot has legs composed of channel bar the legs and are formed with long slots through which pins extend into the rail sections. The arrangement of the links is such that when the legs are folded against the Fig. 3;
provide tongues on the latter which engage rail sections the links automatically fold T within the legs.
In the accompanying drawings,

'Fig'. 7 is a section onthe line 77 of Fig. 3; and, a
Fig. 8 is a side elevation of one end of the cot frame with" the parts connected thereto partly folded.,
Referring to F igs, 1 and '2 of the drawings, a and a indicate the side rails of the cot frame, each composed of two sections l and 2, connected by a hinge joint I). The side rails have folding extension pieces 4 at their ends to which a Wire fabric 5 is detachably connected whenjthe cot is set up. The c'ot is supported by folding legs 6, and each leg is braced by a link 7 and alatch 8, as hereinafter more particularly described;
' The sections '1 and'2 of'the side'rails are of equal length and composed of metal tubing which is-rectangular in cross section, and
these sections are connected by the joint I),
which is adapted to break upwardly, in folding the. cot, as illustrated in Fig.6. Thejoint is composed of the parts b and b which are secured to the adjacent ends of'the rail sec tions' and are connected together by a hinge pin 9. The part 6 comprises a split sleeve 10, rectangular'i'n cross section, fitting closely aroundthe'rail section 1, the side walls 10 of the sleeve projecting beyond the end of the rail section and adapted to enter the section 2 whenithe cot is setup. As shown, these extended side walls of the sleeve lO'lare bent inwardly, toward one another, along a diagonal line 10 and they are beveled from downwardly from this wall into position to bear against the upper wall 1 of the rail section. This tongue takes the endwise thrust which is applied to the part6 when the rail is straightened and the fabric is applied to the cot. The part Z2 may be secured against movement on the rail section 1 by spotwelding.
The part b ofthe hingecomprises a split sleeve 11 which fitsclosely around the rail section 2, and the sides 11 and top 11 of this part project beyond the rail section 2 so as to overlap the part or fitting b on the section 1. The projecting sides and top of the part b are expanded so that they will fit easily around the top and sides of the part b when the parts of the rail are in alinement as in Fig. 3. Thetop 11 is cut away as shown at 11 to permit the extended top of the part b ,to fold without interfering with the top 11 The sides 11 of the part b have depending ears 11 parallel with the ears 10 of the part-b and the hinge pin 9 extends through the ears on both parts. Artongue of the part b? and engages the end of the rail section 2, to take the end thrust which is a plied to the part b when the cot is set up.
he part b may also be spot welded to the rail section 2, if desired. 7
When the sections of the side rails are brought into alinement, as in Fig. 3, it will part b, on the rail section 1, lie within and.
be noted that the extended ends of the hinge rest upon, the bottom wall of the rail section 2 and that the extended top portion 11 of the part Z2 on the rail section 2 rests upon the top Wall 1 of the rail section 1. This double overlapping of the parts strengthens the joint against any tendency to sag downwardly and the sleeves strengthen the rail sections at their adjacent ends.
The extensions 40f the side rails are of channeled steel, pivoted to the ends of the rails and adapted to fold over and around the upper sides of the rails. The latches 8, pivoted to these extensions, are adapted to engage pins/18 on the legs, and the links 7,
pivoted to the legs, engagepins let on the side rails. The links prevent spreading of the legs and the latcheshold the end extensions of the side. rails down against the tension of the wire fabric 5 which tends to pull the end extensions upwardly. The legs 6 are of channeled steel and each link 7 has one end pivoted at 15 within a leg and it 'ture.
also has a longitudinal slot 7 a through which the pin 14: on the side rail extends. The side rails at the opposite sides of the cot are connected together by folding toggle braces 16. V
The legs fold around the undersides of the rail sections, and, as will be evident from an inspection of Fig. 8, in folding the legs the links automatically fold within them. It is unnecessary to touch the links either in folding or unfolding the cot frame.
' What I claim is:
A side rail for a folding cot frame, composed of two sections of angular metal tubing and an upwardly breaking joint connecting said sections, said jointcomprising sheet metal sleeves fitting around the adja cent ends of the sections, one sleeve having side and top walls extending beyond the section to which it is attached and adapted to fit around the sides and top of the sleeve on the opposing section, and the latter sleeve having projecting side walls adapted to enter the opposing section and rest on the bottom ,wall thereof, when the cot is set up, the extendedside" walls 'of both sections having depending ears and a hinge pinextending through said ears.
In test mony whereof affix my signs;
