HAMMOCK-CHAIR.

SPECIFICATION forming part of Letters Patent No. 580,076, dated April 6, 1897. Application filed October 28, 1895. Serial No. 567,121. (No model.)

T 0 all whom it may concern.-

Be it known that 1, JOHN WOHLER, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Hammock-Chair, of which the following is a specification.

My invention relates to improvements in a hammock-chair in which the seat will adjust itself to the position of that portion of the body of the occupant with which it comes in contact.

The objects of my improvements are, first, to afford an easy and comfortable hammockchair; second, to furnish a seat that will give the proper tension to the netting at any angle that the hammock-chair may be placed in.

I attain theobjects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a front view; Fig. 2, a vertical section on the line A B; Fig. 3, a vertical section of the seat on the line A B.

Similar letters refer to similar parts in the several views.

The cross-bar g is attached at the ends to the side bars I) b with bolts, and the seat f is held in position on the cross-bar g by the piece 6, which is fastened to the under part of the seat f, and forms a bearing for the cross-bar g to turn in when the back is lowered, as shown by the dotted lines in Fig. 2.

The netting C is flexible and has loops on both sides, top and bottom. The side bars I) b and top bar h are put through the loops before being fastened together with bolts at the corners. The loops on the bottom of the netting are fastened through holes to a cord passed through the loops on the under side of the back edge of the seat f. The loops on the sides of the flexible netting O are loose on the side bars b b, so the loops can move automatically to where the strain on the netting may require them to relieve the strain on the netting from the piece h to seatf by the cross-strain from bar I) to bar I) and brings the strain from the weight of the occupant on the netting on both side bars b 1), top bar h, and seat f alike.

The rotation of the seat f on the cross-bar g gives the netting the proper tension at whatever angle the hammock-chair may be placed or the position of the occupant may require. From the cross-bar g the proportion between the'front and back part of the seat f is carefully calculated, so that the seat will adjust itself to a comfortable and easy position to the occupant.

The hammock-chair is held in position by the ropes t t and 0 0, which are fastened to the four corners of the frame and pass through holesin the slidingpiecesmm and an, thence through a casting S and into the ends of the sliding pieces m m and n n, as shown in Fig. 2. The sliding pieces m m and n n are within easy reach of the person occupying the hammock-chair. The seat is raised or lowered by pulling down the ends of the sliding pieces m m, in which the ropes are fastened first, then moving the ends through which the ropes pass up or down, as may be desired. The sliding pieces 'm m and n n work automatically, so that the least Weight on the hammock-chair will pull the ends in which the ropes are fastened up, which fastens the ends through which the ropes pass to the ropes and prevents the chair from slipping down. The back can be moved to any angle that may be required by moving the sliding pieces 72 n up or down.

The casting S is cast with one small eye or opening on each side and a larger eye or opening in the center, through which the ropes o 0 and t pass, and the bottom of the eyes or openings have a convex surface, so that the ropes can pass over freely. The large eye or opening in the center is also used in attaching the hammock-chair to a porch, tree, arbor, or any suitable place where the hammock-chair can be used by means of a rope or hook.

What I claim as my invention, and desire to secure by Letters Patent, is

In a hammock-chair a back frame comprising the bars I), b, h, a cross-bar g, connecting the bars I), b, a seat journaled on the crossbar g, a piece E, secured to the seat and embracing the cross-bar g, to hold the seat on the said bar and a back fabric connected to the back frame-bars and seat, the connection of the said fabric to the said frame-bars, consisting of loops formed in the fabric encircling and slidable on the said bars substantially as herein described.
