Patented May 19, 1931 UNITED STATES PATENT OFFICE FRED G. MANLY OF CHICAGO, ILLINOIS, ASSIGNOR, BY MESNE ASSIGNMENTS, TO

GEORGE I. GOLDWYN AND HERMAN GOLDWYN, BOTH OF CHICAGO, ILLINOIS, C0- TARTNERS, DOING BUSINESS AS G OLDWYN BROTHERS FOLDING COT Application filed April 20, 1925. Serial No. 24,398.

provide a folding cot which is strong and rigid and light in weight and which may be quickly and easily setup or taken down and folded into a relatively small compact bundle. H

Another object of the invention is to provide a cot of the kind described in which the use of wood as well as folding brace bars between the legs andframe are entirely eliminated.

Still another object" of the invention is to provide a cot of the kind mentioned, wherein the entire frame thereof including the side bars or rails, legs and end bars are made'of lightmetallic tubing, the several parts'being operatively connected together for compact folding relation by means later described.

These objects of the invention, together with others,.as well as the several advantages thereof will more fullyappear as I proceed with my specification.

Fig. 7111s a perspective view of one of the bracket platesconnecting jonefiof the end legs to one end ofone of the side bars ofthe cot.

In general, my improved comprises air are are? atriathafsinea esls ing foldin side rails or bars, removable end bars, and olding X shaped legs, all made of light weight tubular stock, and said parts are so arranged that when in the extended or set up position a strong rigid cot is provided, and when folded the same comprises a relatively small compact bundle or package,

most convenient for shipment or carrying sections or parts 5-5 which when the frame is in its open extended position meet or abut at their inner ends in the plane of the intermediate legs 4t and engage the top ends of said legs which provide stops for the meeting ends of said side bar parts orsections, as best shown in Fig. 3. In the outer end of each side bar section is a notch 6 which opens through the end portion of said sections, that part 6 of said end portion below the notch being shorter than the top part 6 above the notch as is best shown in Fig. 5. Spaced inward from each notch is a short longitudiii ally extending slot 7 as is best shown in said 1g. Each pair of end legs 33'is made up of crossed leg members 8 and 9 respectively, the

. leg member 9 comprising two offset sections 9 9 suitably connected at their adjacent ends by spaced plates1010, which also embrace opposite sides of the leg member 8 at a point between its ends and are pivoted thereto as at 11 in Fig. 1. To the top end of the leg member 8 and to the top end of the legseotion 9 are rigidly attached brackets 12 by means of which the end legs are operatively connected to the ends of the side bars or rails of the frame. Each bracket comprises two bracket members 1212, one of which is shown in perspective in Fig. 7. Each member comprises a body portion l3 and a I of said legs 8 and leg section 9" and being secured thereto by rivets 15 The head portions of said bracket members each. includes a relatively short lateral extension 16and a V relatively long lateral extension 17, the shortextensions of two coasting plates beingconnected togethei b y a rivet 16 an d thelong r the slot? in the ends of the side i'ailsections i approximates extensions of said plates beingconnected to.-

At the sides thereof are longitudinally extending pockets .28 formed by stitching the canvas in the manner well known and in which the side rails are enclosed and at the endsare formed similar pockets 29 to receive the end bars 2-2. The corners of said fabric top and portions ofit-s sides are cutaway at a point midway between the ends thereof, as at '3Oand31' to permit movement of the various bracket members.

Assume that the parts are in the folded position as shown in Fig. 2 and that it isdesired toopen the cot into its extended position ready for use. The sectional parts 5+5 of eachside' rail are swung'about their pivotal connection 24 with the T-shaped brackets 2020 after which the end'jlegs 33"are swung aboutfthe pivots 1 8 'so'as' to'extend into 'afpositio'n at a right angleto the planeof the side rails and parallel with? the inter- .inediate legs 4; With the parts .in this, posi- "rtisinrthe Slide s swung aterally may from each other 'about 'the pivots" l1 of-the legs 3 and {as an axis, which of course opens the legs into their crossed positions.

While in describing my invention I have referred to certain details of construction, form and arrangement of parts, this is to be taken for the purpose of illustration only so that therefore I do not wish to be limited thereto except as may be pointed out in the appended claim.

I claim as my invention:

A folding cot comprising horizontally disposed sectional side frame members, each provided at its ends with a longitudinally extending slot and a longitudinally extending notch, crossed leg members supporting said side frame members, a bracket fixed to each leg member and carrying parallel pins, one of said pins extending through one of the slots in the side frame member and the other pin being adapted to engage one of the notches of the side frame member when one of the le members is in a certain position and moved lengthwise of the side frame member, a sheet connecting the side frame members, and end bars connected to the sheet and bearing against said brackets for holding certain of the pins in said notches.

In testimony whereof, I have hereunto set my hand, this 27th day of March, 1925.

FRED G. MANLY.
