To all whom it may concern.-

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

My invention relates to folding cots, and has for its object to provide a simple inexpensive cot of this character which may be very readily and compactly folded and will be very substantial when unfolded and setup for use.

The invention consists in certain novel features of construction and combination of parts of the folding cot, all as hereinafter described and claimed.

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

Figure 1 is a side elevation of a folding cot embodying my improvement and partly broken away. Fig. 2 is a perspective view of one end of the cot with the wire mattress removed, and Fig. 3 is a longitudinal sectional side elevation of one end of the cot as it appears when the cot is folded. Y The cot is made with a main frame, to which the mattress is attached or held, and folding end legs which support this frame and are formed toprovide head and foot boards when unfolded into positions for use. The main frame comprises two opposite and parallel side rails, A A, which are rigidly connected by crossbars B B, to which the mattress, which may be a wire mattress, G, is attached. Below the level of the cross-bars B B a round, D, is fitted in the opposite side rails, A A, at each end of the cot-frame.

The leg supports and braces at both ends of the cot=frame are made alike; hence a detailed description of the leg and brace at one end of the frame will suffice, and is as follows: The legs proper comprise two bars, E E, which are pivoted at their upper ends by pins 0 e to the opposite side rails, A A, of the main frame, and near their lower ends the pair of leg-bars E E are preferably connected by a round, F. The leg-braces comprise two bars, G G. which are pivoted at one end'by pins 9 g to the legbars E E near their lower ends, and these braces G G are connected by lower and upper rounds H H and a top cross bar or slat, l. The upper parts of the braces G G and their slat I and upper round H form the head or foot board of the cot. Each of the braces G is provided at its outer edge with a notch or shoulder, J, which is adapted to look below and onto the round D of the main frame. It will be noticed that the leg-braces G G pass upward between the cross-bar B and round D of the main frame. Metal latch-bars KK, having inbent ends 70 entering holes in the legbraces G, are bent at 70, near their other ends are adapted to be swung upward to look their bent portions it over the round D when the cot is unfolded for use; but these latchbars are not essential and may be dispensed with,

'if desired.

When the cotis folded,the leg supports have positions shown in Fig. 3that is to say, the lowerends of-the leg bars E E are swung to ward the center of the cot, which carries the braces G G downward to disengage their notches J from the round D of the mattressframe, and as the leg-bars E are swung on their pivots 9 into positions parallel with the framerails A the braces G will also be swung about parallel with the rails, and the opposite end parts, M, of the end frame will stop against shouldersa a,provided for the purpose at the extremities of the side rails, A A, of the cotframe.

To unfold the cot into position for use it is only necessary to swing the leg-bars E outward, which will carry the braces G upward between the round D and cross-bar B, between which they will bind quite tightly as the brace-shoulders J strike the round D. In these positions of the leg supports and braces at the opposite ends of the cot the bars E slant outward at their lower ends from their pivots e, and the greater the pressure on the mattress the greater will be the thrust of the leg-brace shoulders J on the rounds D, and pressure against the head or foot boards of the cot-frame cannot throw the legs and their braces out of position; hence the entire cot will be very strong and substantial when set up for use. The latch-bars K, when used, may be swung upward to engage the round D, as will be understood from the aforesaid description.

By passing the leg-braces G between the two cross-bars B D at each end of the cot-frame and shaping orgradually widening the brace, so that they bind between the cross-bars, an effective support is thereby obtained for the end legs of the cot-frame irrespective of the abrupt shoulders J bearing on the cross-bar or IO round D. This gradual widcningofthe braces G toward their central parts to cause them to be bound or clamped between the two end cross bars of the cot-frame is most clearly shown in Fig. 3 of the drawings, which also [5 shows by a dotted line atj how the back inclined edges of the upper parts of the braces maybe continued downward to cut off or dispense with the notches or shoulders J,should this construction be at any time preferred.

2o It will be noticed that the braccshonlders J are arranged to engage the lower sides of the cross-bars or rounds D, while the tapering upper parts of the braces bind between the two crossbars B D, and this construction is clearly 23 distinguishable from that in which leg-braces pass between two end cross-bars, but do not bind between them, and wherein the outer cross-bar is engaged at its inner upper part by notches in the leg-braces, as this last'nained construction will not allow the leg-braces to bind or be clamped between the crossbars, as room must be given between said bars for the brace-notches to leave the cross-bar or round, which they engage when the cot is set up,while in my construction the tapering braces having notches or shoulders which engage the lower faces of the crossbar or round may also bind or be clamped between the two eross-bars,and this will provide an autolnatieand secure lock of the cot-frame to its Iegbraces, which makes a far more substantial structure when the cot is erected for use, as will readily be understood.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A folding cot made with a main frame comprising opposite side rails and two crossbars at or near the end of the side rails, in combination with legs pivoted to the rails, and brace-bars pivoted to the legs and passed 130- tween the cross-bars, which bind or clamp the leg-braces at the end of the main frame, substantially as herein set forth.

2. A folding cot made with a main frame comprising opposite side rails and two crossbars at or near the end of the side rails, in combination with legs pivoted to the rails, and brace-bars pivoted to the legs and passed between the cross-bars, which bind or clamp the leg-braces at the end of the main frame, and said leg-braces provided with notches orshoulders bearing against the lower faces or parts of the cross-bars,substantially as herein set forth.

3. A folding cot made with a main frame comprising opposite side rails and two crossbars at or near the end of the side rails, in combination with legs pivoted to the rails, and brace-bars pivoted to the legs and passed. be tween the cross-bars, which bind or clamp the leg-braces at the end of the main frame, and said braces connected at their tops by a slat, forming a head or foot board, and alsoa stop against the side rails when the leg-supports are folded, substantially as herein set forth.

4. A folding cot made with a main frame 7 comprising opposite side rails, A A, and two cross-bars, B D, at or near each end of the side rails, in combination with folding end supports comprising legs E, pivoted ate to the rails A, braces G,pivoted at 1 to the legs and adapted to bind or be clamped between the Crossbars B D and connected by rounds H, and a slat, I, and said braces provided with shoulders J, adapted to engage the lower faces of the cross-bars or rounds D, substantially as described, for the purposes set forth.
