Application filed June 18, 1883. Serial No. 277,410. 4N0 model.)

T0 (1 whom it may con/c111:

Be it. lcnown that I, EDWKN .l'. 'l t'is'run, a citi- 5 legs are thus l'urnislni-d with a double brace zen of the United States, and a resident; of Cleveland, county of Onyahoga, and State of Ohio, have invented certain new and useful Improvements in ot-Beds, of which the 501- I lowing is a specification, the principle of the invention being herein explained, and the best mode in which I have contemplated applyin that principle so asto distinguish it from other inventions.

My invention consists of certain details of construction hereinafter described and claimed.

Referring to the drawings, Figure l is aplan view of a cot-bod t'rame. Fig. iis a side clevation oi the same. Fig. 3, A, B, and are details showing mode of engagtmient, respect;- ively, between,outer frame and tenon, tenon and leg, and tenon and diagonal brace. Fig. l: is a perspective view of the complete not ready for use.

A is the outer metallic frame of the cot, formed in one piece, the two extremities of which are secured together in any suitable manner, as by riveting. In the longitudinal sides oi said outer frame, A, 1 term a series of mortises, u, in which the reel angular tenons l of the transverselnirs B lit, the extremities oi said bars being then upset against said frame, and thus the braces are rigidly swurcd to the latter. As the metallic bars forming the trams and brace are set on edge. the bed has great rigidity. liars ll, to which the legs are attached, are pniividcd with an elongated tenon, the outer portion of which tits into frame A and is upset like extremities of bars B. legs t, consisting of depending portion r and oblique portion r, are provided at their opposite extremities with openings slightly greater in diameter than the greatest; transverse thickness oi the tenon on bars ll, which thus easily slips into said opening, the legs having pivotal movtmuuitthereon. 'lwo said legs are secured to each said bar 13, the depending portion of one leg and the oblique portion of the complementary leg being thus pivoted on one extremity, while on the opposite extremity is pivoted the oblique portion of the former leg and the depending portion of the latter. The oblique portions are given a halt-turn attheir point 0t contact, so that their flat fares are brought into contact with each other and are then riveted. Each set ot and are rendered very firm and stead against any lateral movement of the cot.

On each side of the cot, pivotally secured to the several legs, is the bar D, extending longitudinally of the cot and connecting together the different legs, so that any motion imparted to one set oi? legs causes the others to move correspondingly. It also serves to brace the several sets against longitudinal strains. livoted to the outer extremity of one of said tenons on either side of the cot the diagonal brace E, provided at its lower extremity with slot that tits over and locks with projecting pin c. lhe woven-wire mattress F is constructed in accordance with application of D. ll. Gail for lfnited. States Letters Pat-- ent, Serial No. Qfitlfltld, tiled March 10, 1888, in which l'have an intercst-mamely, having its strands running transversely of the bed,

and having its outer strai'ids secured to the encircling rod or wire l Spiral. springs G have their lower extremities secured to the transverse braces l5 B by passing through openings b termed in said bars, their upper extremities being woven into the mattress, the springs supporting the center oi? the cot being heavier and stronger than the sprii'igs on the outer portions of the sa1ne,thereb v preventing sagging. l'lead-rest H, formed of woven wire similar to the mattress, is pivotally secured at its lower portion to said mattress. Near its opposite end on either side I pivotally seen re supporting bai-s .l, provid ed with a series of adjustlug-slots that [it on rod F.

\Vhen it is desired to use the cot-bed, the legs are set up atrright angles to the mattress and the slots e in the lock-bars E are slipped over pin 1 thus locking the legs against movement. The height of the head-rest is adjusted and the same seen red by illziillS tJf its supporting-lnirs. and the cot is ready for use.

To told it, the supporting-bars oi theheadrest are .t'recd from engagement with rod 1* and the head'rest laid flat on the mattress. The brace-liars E are then freed from engagement with pins 0 and the legs are laid flat against frame A, the whole folding into a very compact form.

It is evident that as the cot is composed entirely of metal it is light, neat, and possesses greater strength than if composed partly of wood and partly of metal.

It will be noticed that the outer frame, A, and the transverse bars B B are placed on edge, for by so doing a much firmer and stronger cot and one with greater weight-sustaining power obtained than if the bars were turned with the flat faces up.

The foregoing description and accompanying drawings set forth in detail mechanism in embodiment of my invention. Change may therefore be made therein, provided the principles of construction respectively recited in the following claims are employed.

I therefore particularly point out and distinctly claim as my invention 1. In a cot-bed, the combination of a frame with pairs of legs for supporting the same, each leg consisting of a single piece bent at its point of contact with the floor, so as to form a vertical depending part, which is pivoted to said frame, and an oblique brace portion which extends upward across the frame and is pivoted to the opposite side thereof, the oblique brace portions of each pair of legs being also pivotally secured together at their points of crossing'and free to move at their up per ends, substantially as set forth.

2. In a oot bed, the combination of a frame with a pair of legs pivoted thereto on opposite sides and locking mechanism engaging one of said legs to prevent folding, each leg consisting of a single piece bent at the pointof contact with the floor, so as to form an oblique brace portion, which is attached to the opposite side of said frame, but free to move thereon to allow folding, the brace portions of said legs being pivoted together at their points of crossing, substantially as shown.

3. In combination with the frame of a cotbed having transverse bars which are provided with protruding ends, supporting legs arranged in a series of pairs and pivoted on said ends, each leg consisting of a single piece bent at the point of contact with the floor to form an oblique brace portion, which is slotted at its upper end and fits movably on the end of the transverse bar to which said leg is pivoted, the legs of each pair being pivoted on opposite sides of the frame, substantially as set forth.

4. In combination with a cot-bed frame, a series of connected pairs of folding legs, each leg being pivoted thereto at one end, bent at the point of contact with the floor to form an oblique brace portion, pivoted to the companion leg of the pair at the point of crossing and having a slotted pivotal attachment to the opposite side of the frame, allowing'inotion thereon for folding and unfolding, substantially as set forth.

5. In combination with a cot-bed frame, a series of connected pairs of folding legs and a locking device engaging one of said legs to .hold the series against folding, each leg being pivoted to one side of the frame at one end and pivoted at the other end to the other side of said frame free to move, as described, and consisting of a single piece bent at the point of contact with the floor to form an oblique brace portion which is pivoted to the corresponding portion of the companion leg of the pair at theirpoint of crossing, substantially as set forth.

6. In combination with a frame having transverse bars which are provided with journals extending beyond the frame on each side, a series of pairs of legs, connected by bars D and provided with locking mechanism to prevent accidental folding, the legs of each pair being pivoted to opposite pivots or journals of the same transverse bar, and each leg bein g bent to form an oblique brace portion having a slotted attachment to the journal of said transverse bar remote from that journal to which it is pivoted, substantially as shown.

In testimony that I claim the foregoing to be myinvention I have hereunto set my hand this 16th day of June, A. D. 1888.
