CAMP-CHAIR AND COT.

SPE CIPICATION forming part of LettersPatenc No. 295,971, dated April 1, 1884.

Application filed August 27, 1883. (No model.)

of Allegheny City, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Camp-Chair and Cot; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a perspective View of the device arranged as a camp-chair. Fig. 2is a view of the device extended and arranged as a cot. Fig. 3 is a detached view of the fasteninghook. Fig. 4 is a detached view of the fastening-eye, and Fig. 5 is a detached view of the pin which engages with the hooks and eyes.

Like letters of reference indicate like parts wherever they occur.

My invention relates to the construction of a combined camp-chair and cot; and it has for itsobject the production of a light, compact,

and simple folding camp-chair which can at the will of the user be converted into a cot,

5 whereby the advantages of the two articles of furniture are obtained with space and cost,

I will now proceed to describe my invention,

which is an improvement on a combined campchair and cot invented by me, and forming the great saving of subject-matter of Letters Patent No. 280,004,

dated June 26, 1883, so that others skilled in the art to which it appertains may apply the same.

In the drawings, it indicates the rear frame, andb the front frame, composing'the chair or cot. This rear frame, a, which, as it forms the back of the chair, exceeds the length of the front frame by one-half, more or less, is composed of two longitudinal bars, a a which are slightly curved or 'bent, and are united or joined by cross-bars a. At the upper end of the frame a is a sacking-roller, c, to which one end of the sacking c is secured, the opposite end of the sacking being secured to the cross-bar b 'of the frame b. On the ends of i the sacking-roller c are ratchet-wheels c and secured to the frame a are suitable dogs for locking the roller. Pivoted to the journals of the roller 0 are supplemental legs (I, which are only used as such when the devlces are extended to form a cot. These legs are connected by a cross-bar, d. They also serve as a clutchcrank, to wind the sacking on the roller 0 by means of the pawls (P, which are pivoted thereto, so as to engage with the teeth of the ratchet-wheels 0 The roller may, however, be provided with a separate crank for accomplishing the same purpose. Each legd is provided with a pivoted hookfd which engages with eyes (2" on the frame a, so as to brace the legs (2 when they are set to support the head of the cot. On the upper part of each bar a a of the frame a is a slide, 6, which may be moved up and down, turned on the bar, and secured by a set-screw, pin, or other suitable device at any desired point, and to these slides e are pivoted braces or stretcher-bars]; having open slots f in their lower ends, which engage with pins f situated at the lower ends of the bars a a so as to form the side pieces or arms of the chair, and when the device is extended to form a cot the bars f are stretched across from the frame a to the frame I), the notches f engaging with pins 0' on the side of the bars 2/ b so as to serve as braces. On the lower end of the'bar a, on the inner side thereof, is an eye, 9, and on the lower end of the bar a is a hook, it, which eye and hook engage with pins i i on the lower end of the bars b b, when the device is arranged as a cot.

The frame I), when the device is arranged as a chair, is attached to the frame a by a similar hook and eye, /h, engaging with pins t" t" on the bars 1) b so that the frame a and the frame I) together form a cross or X frame, as shown in Fig. 1. Secured to the under side of the sacking c is a crossbar, m, of a greater.

length than the distance between the bars a i bar m, when the device is inthe form of a chair, is placed back of the frame a, so that its ends rest and bear against the rear faces of the bars a a and thereby the sacking which forms the seat and back of the chair is kept taut.

XVhen the device is to be formed into cot, the sacking is loosened by releasing the roller 0, and the bar m is turned end first and passed between the bars a a so as to allow the sacking to be stretched between the upper endsof the frames at and b.'

Hinged to each of the stretcher-bars f is a IOO horizontal arm, n, which extends from the bar, and is hinged or pivoted at its outer end to a; supporting rod, 0, which rod extends downward and is hinged at its lower end to a ring, which slides on the barf. This ring is held in place on the bar f by aspring-catch, 0 Instead of placing the ring 0 on the bar f, it may be arranged to slide on a bar attached to the stretcher-bar or attached to the bar a of theframe a. When the device is to be used in the form of a cot, or is to be folded for transportation, the ring 0 is released from the spring-catch 0 and is pushed down, thereby bringing the arm 7% and rod 0 flat against the stretcher-bar.

In order to change the device when in the form of a chair to the form of a cot, the front frame, I), is disconnected from the rear frame, a, by disengaging the pins i from the hook g and eye h. The sacking 0 is then unwound from the roller 0, and the cross-barm is passed between the bars a a to the front of the frame a, the pins 2' 2', at the ends of the bars 5 b", are fitted into or engaged with the eye gand hook h at the end of the bars (6 a", the set-screws 00 are loosened, the slotsf are disengaged from the pins the rings 6 are brought down on the bars a a and the open slots f are caused to engage with the pins 6. The arms a n are then brought down on the stretcher-bars f, as already described, and the supplemental legs dare placed in position and secured by the hooks (P. This produces a cot, as shown in Fig. 2.

The advantages of my invention are its simplicity, durability, cheapness, lightness, and also the ease and rapidity with which the device may be transformed from a chair to a cot or folded for transportation.

Although I have described the arm n as adapted to my improved chair, it may be fitted in a like manner to the frame of other camp and folding chairs.

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

1. The combination, in a combined convertible chair and cot, of the rear frame composed of the side bars a a and cross-bars a, the side bars being provided with eyes 9 g and hooks h h at the ends and crossing points of the frame, the front frame composed of the side bars b b and cross-bars b the side bars being provided with the pins 2' i and z" z" to en gage with the hooks and eyes of the rear frame, and an extensible sacking which connects the front and rear frames, substantially as and for the purposes specified.

2. In a combined convertible chair and cot, the combination of two cross-frames adj ustable on each other, an extensible sacking which connects the two cross-frames, and a cross-bar whose length exceeds the distance between the sidebars of the rear cross-frame, said crossbar secured to the sacking at or near thefront third thereof, whereby the cross-bar may be made to engage with the rear C1OSS-fl.2Lm0, or may be disengaged therefrom, substantially as and for the purposes specified.

8. In combination with a folding chair, an arm pivoted or hinged at one end to the frame of the chair, a support pivoted or hinged to the arm, a sliding ring to which the arm-support is pivoted or hinged, and a locking device for holding the sliding ring, substantially as and for the purposes specified.

In testimony whereof I have hereunto set my hand this 20th day of August, A. D. 1883.
