ADJUSTABLE CAMP CHAIR OR HAMMOCK.

SPECIFICATION forming part of Letters Patent No. 327,441, dated. September 29, 1885.

Application filed August ll, 1884.

T 0 all whom it may concern.-

Be it known that I, ARTHUR OGDEN HUB- BARD, a citizen of the United States, and a resident of St. Cloud, in the county of Stearns, in the State of Minnesota, have invented certain new and useful Improvements in Adjustable Camp Chairs or Hammocks, of which the following specification is a full, clear, and exact description, reference being also had to the accompanying drawings, in which- Figure 1 is a side view, Fig. 2 is a plan view, and Fig. 3 is a rear view, of the chair complete. Fig. 4is an enlarged sectional view of a section of one of the sides, illustrating the manner of forming the combined hinge and suspension-cord. Fig. 5 is a perspective view of a pair of the side arms or bars detached. Figs. 6 and 7 are detached details illustrating slight variations in the manner of constructing the adjusting side braces.

The body of the chair or hammock consists of a seat-section, a foot or lower section, and a back or upper section. The foot-section consists of two side bars, A A and a cross-bar, A the ends of the cross-bar fitting into mortises in the ends of the side bars. The seatsection consists of two pieces, A A and the back section consists of side pieces A A and cross-piece A the ends of the latter fitting into mortises in the ends of theside pieces, A A similar to the cross-piece A in the sides A A.

Into each end of the side pieces A A and also into the upper ends of the sides A A" and the lower ends of the sides A A holes are bored for a short distance, and into the inner ends of these h oles other holes are boredat right angles to them.

Small ropes B B5B B" are passed through the holes in each of these pieces and knotted at the ends, while the main ropes are passed upward at a through holes in the pieces A A and A A as shown, and attached in any convenient manner to a support above, the latter not being shown. By this simple arrangement each rope forms a hinge between the parts, and also a means of suspending the chair.

A single web of cloth, 0, is sewed over the pieces A A A A A A A A the tension of the cloth being sufficient to hold the pieces A A in place without further fastening, while (No model.)

the rope hinges hold the sections together, but at the same time leave them flexible enough to be bent to any desired position, as shown in Fig. 1.

D D are two bars attached to the tops of the pieces A A lengthwise outside the cloth, and having notched slots bzon their under sides.

d d are two small ropes which fit beneath these slots b and inwrap and hold the ends of a foot-rest, E.

By moving the ropes upward or downward and allowing them to catch upon the notches in the slots 0 the foot-rest may be adjusted and held at any desired point of elevation to adapt the chair to persons of different heights.

The upper ends of the bars D D are curved upward away from the pieces AA as shown,

and are provided with small pins e, projecting y from the sides of their upper ends.

F F are two brackets or blocks attached to the sides A A and provided with pins 6 similar to the pins 0.

G G- and G G* are two sets of parallel bars, each set being connected by blocks h h near their centers and adapted to fit by their ends over the pins 6' c, as shown.

The blocks h h project down below the bars G Gr G" G* to form stops to prevent the chair being tilted forward or backward too far, as hereinafter shown.

H H are two bars or braces jointed at i, and one end of each pointed and fitting into suitable cavities in the inner lower corners of the sides A A Each of these braces is provided with notches 1?, over which links or straps 2"", pivoted in the free ends of each of the braces, fit, so that by moving the links inward or outward 011 the notches the braces may be moved away from or nearer to each other to increase or decrease the distance apart of the ends which fit into the cavities in the sides A A and thus spread them and hold them apart and keep the canvas or web stretched tight. Similar braces, H H*, are arranged on the sides A A and a pair may also be arranged beneath the seat-section, if required. The adjustable feature of these braces also enables me to take up the slack of the canvas or web in event of its stretching too far.

Only one of the links 1' may be used, if preferred, as one link is sufficient for all practical purposes.

In Figs. 6 and 7 two different systems of levers are shown to take the place of the side bars, G G G G, and their connections; but the action is the same.

Having described my invention and set forth its merits, what I claim is 1. A hammock-chair consisting of foot-section side bars, A A having nlortises in their lower ends, crossbar A fitting by its ends in said mortises, back-section side bars A A having mortises in their upper ends, and with crossbar A fitting into said niortises, seatsection side bars A A interposed between said foot and back section side bars, flexibly jointed thereto by combined suspension and jointing cords B B B B", and a web or canvas covering, 0, substantially as and for the 20 ARTHUR OGDEN HUBBARD.
