FOLDING COT.

SPECIFICATION forming part of Letters Patent No. 554,098, dated February 4, 1896.

Application filed September 4, 1895. Serial No. 561,466. (No model.)

To aZZ whom it may concern:

Be it known that I, EDWIN F. TILLEY, of New York city, in the county and State of New York, have invented a new and Im pro ved Folding Cot, of which the following is a full, clear, and exact description.

The object of this invention -is to produce a cot having superior features of construction, whereby it may fold to a more compact position and with greater ease than heretofore; and to. this end the invention comprises a mattress-frame to which end posts are connected by means of links, and the mattress-frame has angle-irons extended therefrom which are formed with notches in each portion so as to receive two parts of the respective posts and by this dual connection to effect a more secure and rigid structure. 7

The invention will be fully described hereinafter and finally embodied in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective View of a cot con structed after the manner of myinvention. Fig. 2 is a vertical longitudinal section thereof. Fig. 3 is a similar view showing the cot folded. Fig. 4 is a detail and enlarged perspective view illustrating one corner of the cot. Fig. 5 is a view similar to Fig. 4, parts being dispensed with in the interest of clearness; and Figs. 6 and 7 are fragmentary elevations showing still further the manner of connecting the parts.

The mattress -frame of my improved cot comprises two angle-iron side rails a, which are arranged with the angle at the inside and which have riveted or otherwise secured thereto the end angle-rails b, said angle end rails being two in number and being held perpendicular to the side rails by suitable braces c. The wire mattress d is clamped to the end rails 19 by means of cleats d, and is of the usual construction.

The posts e are essentially rigidly connected to each other at the head and foot of the cot, and in the drawings this is shown to be effected by forming each pair of posts of an integral piece of material, and further bracing them by means of cross-braces c. This is not essential, however, since any construction serving to rigidly connect the posts may be resorted to. The posts are connected to the mattress-frame by means of links f, said links being one for each post and being arranged to extend at approximately an angle of forty-five degrees from the posts when said posts are in a vertical position. The posts are provided with the usual casters 9.

Each end of the two side rails a is extended beyond the end rails b and is formed with a semicircular notch h in its horizontal portion, said notch being of a radius equal to approximately the width of the horizontal portion of the side rail, and the vertical portion of each side rail is formed with a slightly verticallyelongated slot '5. The vertical portion of each end of the side rails a is extended beyond the horizontal portion. to form a lip t" which carries one-half of the slot t'.

The posts 6 are arranged so as to be received in the semicircular notches h when the parts are vertically disposed, and each pair of posts is provided with a brace-rod k, the same being intermediate of the braces e, and these braces are adapted to be received by the slot 1' of the vertical portions of the side rails a when the cot is in operative adjustment, as shown best by Figs. 4 and 5.

From the above description it will be seen that a cot so constructed may be arranged as in Figs. 1 and 2 and that its parts will be held with all possible rigidity, for by means of the double arrangement of the notches h and slots 1' the posts are held to the mattress-frame so as to be incapable of any loose movement,

which holding is assisted by means of thelinks f, the same serving in the capacity of braces when the cot is in operative adjustment.

To fold the cot all that will be necessary is to raise the ends of the mattressframe so that the slots 7; will be disengaged from the bracerods 70, whereupon the connected head and foot posts may respectively swing on the links f and under the mattress-frame and parallel therewith, as shown in Fig. 3, and owing to the universal connection which is effected by means of the links f the outer extremities of the posts when folded will be approximately aligned with the outer ends of the mattressframe, thus taking up no more room than is taken up by the frame itself and consequently reducing the folded structure to the smallest possible bulk.

The notches 7L serve to hold the posts against lateral displacement, While the slots i are effective in preventing the posts from moving on the links f, as will be seen.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A cot, the same comprising a mattressframe having two side rails, each being an angle-iron and each having a horizontal and a vertical member, the vertical members being at the respective inner edges of the horizontal members, each angle-iron having its ends extended beyond the ends of the n1attress-frame and having a notch in each member, the notches in each end being disposed at right angles to each other, two pairs of legs, the legs of each pair being rigidly connected with each other and each pair being respectively pivotally mounted at the head and foot of the bed, and atransverse brace for each pair of legs, the parts being arranged to permit the respective braces to move into the slots of the vertical members of the angleirons at the respective ends of the mattressframe and to permit the respective legs to move into the slots of the horizontal members of the ang1e-irons, substantially as described.

2. In a cot, the combination of a mattressframe having at each corner a longitudinallyextended angle-iron, said irons having an opening in each of their members, the openings of each angle-iron extending at approximately right angles to each other, the pairs of legs for the frame, links pivotally connecting the legs to the mattress-frame, and two cross-braces for the legs said braces being rigidly connected one to each pair of legs, the ends of the braces being respectively received in one notch of each angle-iron. and the legs being respectively received in the remaining notches, substantially as described.
