CHAIR.

SPECIFICATION forming part of Letters Patent No. 572,503, dated December 1, 1896.

To all whom it may concern.-

Be it known that I, WILLIAM H. DAVY, a citizen of the United States, residing at Pewaukee, in the county of Waukesha and State of Wisconsin, have invented new and useful Improvements in Chairs, of which the following is a specification.

My invention relates to improvements in combined rocker and high or stationary chairs designed principally for use by infants.

The object of my invention is to provide a chair which may be easily and quickly converted from a rocking-chair to a high or stationary chair, or from a stationary chair to a rocking-chair, to suit the convenience of the user.

In the following description reference is had to the accompanying drawings, in which Figure 1 is a side elevation of my invention as it appears when used as a high chair. Fig. 2 is a'front elevation of the same. Fig. 3 is a side elevation of the invention when used as a rocker. Fig. 4 is a detail view in section, drawn on the line X X of Fig. 2.

Like parts are identified by the same reference-letters throughout the several views.

The seat A is supported from the curved front and rear legs B B by the supportingbars 0 O, the latter being hinged to the seat at a a and to the'legs at b b. When used as a high chair, the front and rear legs are kept from spreading by the hook D and catch E, as shown in Fig. 1. The foot-rest F is attached to the bar 0.

The upper ends of the legsB B are connected together by flat strips of iron G G,

hinged together at g and having curved edges conforming to the curves of the legs. When used as a rocking-chair, the hook D is released from the catch and the legs permitted Application filed February 21, 1896. Serial No. 5 80,167. (No model.)

to spread until the upper ends meet, as shown in Fig. 3, the front and rear legs forming the respective halves of the rocker. In this position the upper ends of the seat-supporting bars 0 and O are supported by the one-way toggle-jointed levers H and H, the respective ends of which are connected with cross-rungs I I and J J, respectively, as shown. These levers are also of service in holding the respective halves of the rockers in position, but when used as a high chair the levers are folded, as best shown in Fig. 4:.

It is obvious, that by altering the length of the legs the height of the stationary chair is varied accordingly, and I do not therefore limit myself to any particular length of rocker or corresponding height of the stationary chair.

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

A chair, consisting in the combination of the seat, the curved front and rear legs provided with metallic plates at their upper ends hinged together to form a one-way joint, seatsupporting bars hinged to the seat and legs, cross-rungs connecting the upper ends of the legs and the upper ends of said bars, and toggle-jointed levers connecting the cross-rungs of the legs with those of the bars, whereby the seat may be supported by the bars and levers when the legs are used as rockers, substantially as described.

In testimony whereof I affix my signature in the presence of two witnesses.
