COT.

. Specification of Letters Patent. -Patented Dec. 10, 1918 Application filed January 18, 1917. Serial No. 142,978.

To all whom it may concern Be it known that I, JosnPH GANnoN, a citizen of the United States, residing at \Valton, in the county of Delaware and State of New York, have invented certain new and useful Improvements in Cots, of which the following is a specification.

My invention relates tofolding cots, and has for its object to provide a simple, strong and durable structure in which provision is made for keeping the top stretched at all times.

Other objects and aims of the invention, more or less broad than those stated above, together with the advantages inherent, will be in part obvious and in part specifically referred to in the course of the following description of the elements, combinations, arrangements of parts, and applications of principles constituting the invention; and the scope of protection contemplated will appear from the claims.

In the accompanying drawings, which are to be taken as a part of this specification, and in which I have shown a merely preferred form of embodiment of the invention, Figure l is a partial side elevation of a cot embodying my invention; Fig. 2 is an end view thereof; Fig. 3 is an end view of the cot frame folded; Fig. 4 is a partial side view of the cot frame in its folded position; Fig. 5 is a view showing the detail, the legs and the brace connected therewith in side view and end view; Fig. 6 illustrates in detail in edge and face view a form of connection between the braces; Figs. 7 and 8 illustrate views similar to Fig. 6, as modifications.

Referring to the numerals on the drawings, the cot frame comprises legs 9 and 10 pivotally connected at 11 so that they can be folded together as in Fig. 3, or opened into X shape, as in Fig. 2. Each of these legs has connected thereto adjacent its upper end a hook or other means 12 for the attachment of the folding top, which is usually made of canvas or the like, indicated in the drawings at 14:.

The general construction of the cot is familiar in the art and is exemplified in United States Letters Patent No. 793,723 to R. L. Herman of July 4th, 1915. Between the several pairs of legs on each side of the cot are braces indicated in Fig. 1 by the numerals 15 and 16. These braces have heretofore been pivoted together at their point of crossing, and their ends have been connected to the legs by means of pin and slot connections, as shown in the said Herman patent. It has been found in practice that this construction is objectionable, because the slotting of the braces at their ends weakens them at the point where strength is most required, and because of the likelihood of rusting and binding. According to the present invention the braces are not connected to the legs by pin and slot connections but are merely pivoted at their ends to swinging brackets carried by the legs, these swinging brackets being indicated by the numeral 17 in Fig. 5, and the pivotal connection between this swinging bracket and the braces being indicated at 18 in said figure. And in order to accomplish the result of permitting adjacent pairs of legs to move relatively to each other without changing the pivotal relation of the legs'of any pair, whereby slack due to the stretching of the canvas top may be taken up, I prefer to provide such a construction as is shown in Figs. 6, 7 or 8 of the drawings. In Fig. 6 one of a pair of braces is indicated by the reference character 19 and the other by the reference character 20. In Fig. 6 the brace 19 is in one piece while the brace 20 is in two pieces, the ends of the brace 20 being pivoted on a disk 21. As shown in Fig. 6 the brace 19 is at one side of the disk, pivotally connected thereto as indicated at 22, while pivots 24 for the ends of the two parts of the brace 20 extend to the other side of the disk 21. In the modification of Fig. 7 both the brace 20 and the brace 19 are in two parts, having their ends pivoted to the disk 21 as by means of the pivots '25. And in Fig. 8 I provide two of the disks 21, and both of the braces are in two pieces, the ends of one of the braces being pivoted to one of the disks and the ends of the other brace being pivoted to the other disk, the disks being mounted on a concentric axle or pivot 26. It will be evident that by this construction the pairs of legs may move relatively to each other without causing any change in the pivotal relation of the legs of a pair, and at the same time the braces are not weakened but are on the contrary strengthened. It will be understood that the amount of this movement between pairs of legs need only be very slight, suiticient to take up any slack in the canvas top due to stretching.

Inasmuch as many changes could be made in the above construction, and many apparently widely different embodiments of my invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

It is also to be" understood that the language used in the following claims is intended to cover all the generic and specific features of the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.

I claim:

1. In a device of the kind described, a support, a disk rotatively mounted thereon and a two-piece brace having its ends pivoted to the disk.

9.. In a device of the kind described, a pair of disks, an axis on which they are mounted for rotation, and a pair of two-piece braces, the ends of one of said two-piece braces being pivotally connected to one of the disks and the ends of the other two-piece brace be ing pivotally connected to the other disk,

3. A folding cot comprising pivotally con nected pairs of legs, sectional braces pivotally secured to said legs and a compensating disk having pivotal connection with said sections.

4. A folding cot comprising pivotally con nected pairs of legs, sectional braces piv0tally secured to and arranged between said legs and a compensating disk connecting said braces.

5. A folding cot comprising pivotally connected pairs of legs, a compensating disk, braces pivotally connected to the disk at one end and at the opposite end pivotally connected to said legs.

6. A folding cot comprising pivotally connected pairs of legs, a compensating disk and a pair of braces, said braces being pivotally connected tothe disk at one end and to the legs at the opposite end.

7 A folding cot comprising pivotally connected pairs of legs, braces pivotally secured to and arranged between said legs and a compensating disk pivotally secured to and arranged between the braces.

In testimony whereof I aflix my signature in presence of two witnesses.

JOSEPH GANNOK.
