IMPRovED Roemer-CHAIR The Schedule referred to in these Letters Patent and making part of vthe same.

To all whom 'it may concern Be it known that I, GEORGE H. SPAULDING, `of Rockford, in the county of Winnebago, and State of Illinois, have inventeda new and valuable Improvement in Rocking-Chairs; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of thev same, reference being had tothe annexed drawings, making a part of this specification, and to the letters and gures of ref-V erenoe marked thereon.

`Figure 1 `of the drawings is a longitudinal sectional view of the device. I

Figure 2 is .a plan view of the rockers and foot-board of the same. v l

My invention relates to rocking-chairs and .y

It consists mainly in devices so constructed as to preserve the centre of gravity to the person occupying the chair, when thrown too far backward or. forward, thus preventingr accidents by upsetting.

Letter A'represents the bodyof the chair;

Letter B, the legs; and

C, the rockers.

Letter D represents the footoard.V

LetterE is an elastiosteel spring,tbe lower end screwed to the upper surfacerof the rockers,`nea1" their. centre, by'means of set-screws. f i

The upper end of the' spring is screwed to the bottoms of the front legs of the'V chair, by means of a slot in the end of the spring, which slips under AaV screwhead in the bottom of the front legs.

Letter a represents the screw-head. Letter b is a hinged joint, uniting the back legs of the chair to the upper surface of the rocker, in man ner as set forth in the drawings. v

My invention is operated as follows: When-a person sits in this rocking-chair, by pressing the feet against the foot-board D, and the back against the back of the chair B, the spring E allows the weight of the occupant to `bala-nce over the centre 'of the rocker, and by re.ieving the weight from the foot-board, the chair inclines forward, thus restoring' the centre of gravity, when it is found necessary so to do. What I claim as my invention, anddesire to secure by LettersPatent, is l A rocking-chair, constructed as herein specified, and having hinged joint b, elasticY steel spring E,and footboard D, arranged'and operating substantiallyas de- In testimony that I claim the above,I vhave hereuntov subscribed my name, in the 'presence of two witnesses.
