CHAIR.V

SPECIFICATION forming part of Letters Patent No. 416,324, dated December 3, 1889.

Application filed June 1l, 1889. Serial No. 313,832. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM G. CROSS, a citizen of the United States, residing at Little Falls, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Chairs; and I do declare the following to be a full, clear, 4and eX- act description of the invention, such as will enable others skilled in the art to'which it appertains to make and use the same, reference bein g had to the accompanying drawings7 and to the letters of reference marked thereon, which forma part of this specication.

My invention relates to improvements in chairs, and has especial reference to what may be termed an adjustable chair;7 adapted to be used by infants, or for a piano-stool, or, in fact, in any case where such a chair could be employed.

The leading object of the invention is the production of a chair which can be quickly adjusted to suit the purpose of the user.

A further object is the provision of an adjustable chair which will be attractive and ornamental in appearance, and, further, to provide a chair of the character and for the purposes mentioned which will be of simple and durable construction and inexpensive to produce.

Finally, the invention consists in the novel construction and combination of parts, substantially as illustrated, described, and speciically claimed.

Figure l represents a perspective view of an adjustable chair constructed in accordance with and embodying my invention. Fig. 2 represents a rear elevation thereof. Fig. 3 represents an inverted plan view of the chair, partly in section; and Fig. 4 represents a detail view of va part of the chair.

' Referring by letter to the drawings, in which similar letters of reference denote corresponding parts in said iigures, A designates the inclined standards, supports, or uprights, which are connected at top and bottom by the rounds B, and the inclined standards are supported by the auxiliary inclined supporting-legs C, which are connected by a round D, and the lower round B of the inclined standards and the round D are connected by bars E, the whole forming a durable and reliable supporting structure. The inner sides or faces of the inclined -standards A are provided with grooves, channels, or ways F, which are provided with openings or notches Gr.

I-I designates the chair proper, the backJ of which is similarly inclined with the inclined standards, and said back J is provided with lateral cleats or tongues K, fitting in and adapted to travel in the ways F. From this construction it will be seen. that the chair is adapted to move in the inclined ways, and in order to retain the chair at any desired place I employ a novel mechanism.

To the seat of the chair I pivotalever L, to the inner end of which is connected a spring M, said spring being also connected to the chair-seat. To each side of the lever, on opposite sides of the fulcrum or pivot thereof,I loosely connect the inner ends N of rods N', having their outer ends N2 passing through openings in the chair-back and engaging the notches or openings in the inclined ways of the standards. The rods are bent, as shown, near their inner ends.

When the parts of the chair are in normal position, as shown in Figs. 1, 2, and 3 of the drawings, and it is desired to adj ust the chair, the lever is moved, as indicated by dotted lines in Fig. 3, and by reason of the connection of the rods therewith they are withdrawn from engagement with the notches in the standards, allowing the chair to be moved to the desired position, and the release of the lever allows the rods to engage the notches and retain the chair.

The manner of using my improved chair is as follows: The chair is adjusted aso desired by releasing the rods and moving the chair to the desired point, which, when reached, the rods are allowed to engage the desired notches or openings, and the chair is held in the proper place, as will be readily understood.

The top rail'of the back of the chair, it will be noticed, extends at its ends beyond the standards, and thereby forms a stop, or, in other words, prevents the chair from backward movement or tipping, and also provides an easy rest for the occupant of the chair.

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

The herein-described chair, consisting of the standards having the passages or channels on IOO 1o their outer ends passing through openings in the chair and entering the openings of the standards for retaining the chair in the desired position, substantially as described.

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

VILLIAM G. CROSS.
