NURSERY-CHAIR.

SPECIFICATION forming part of Letters Patent N 0. 596,204, dated December 28, 1897. Application filed August 12, 1896. Serial No. 602,504. (No model.)

To all whom it may concern:

Be it known that I, S SPENCER EOOLESTON, a citizen of the United States, residing at Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Nursery-Chairs, of which the following, taken in connection With the accompanying drawings, is a full, clear, and exact description.

My invention relates to nursery-chairs, and the object is to provide a simple and durable chair that may be quickly and easily adjusted to any suitable elevation and that may re volve on its base.

My invention consists in certain details of construction which will be hereinafter described, and specifically set forth in the claim.

In the drawings hereto annexed and forming a part of this specification, Figure 1 is a side elevation of a chair embodying my invention. Fig. 2 is a front view of the upper part of the chair. Fig. 3 is a rear view of the tray. Fig. 4 is a side elevation of the base with the spindle raised to its highest notch. Fig. 5 is a detail view of the spring-catch, and Fig. 6 is an enlarged view of the treadle for operating the spring-catch with the foot.

Referring specifically to the drawings, A is the base, comprising the legs, rounds, and a board a, in which the upper ends of the legs are inserted, and B is the seat, with a back, side arms, and a foot-rest, as usual. Secured rigidly to the center of the seat,upon its lower side, is a vertical spindle 0, having angular saw or ratch teeth encircling it. This spindle extends through the center of the board a of the base A and also through a narrow board or cross-piece 6 below the board a, secured at its ends to the legs. Upon the upper side of the board I) is a sliding springbolt 0, which has one end passing through one of the legs and the other or flat end engaging the teeth on the spindle O. The bolt is held upon the board I) by means of ascrew c, passing through a slot 0 in the bolt. .A curved recess f in the flat end of the bolt allows it to embrace the spindle and provide a better bearing. The coil-spring (1 lies between a projection on the bolt and one of the legs and serves to force the bolt toward the spindle C. If the spring is not too stifi, the seat maybe raised without pressing back the bolt by hand. Otherwise and when the seat is to be lowered the bolt is pressed back by hand or by means of a simple treadle D,which is bifurcated and recessed in the bifurcation, so that it may be sprung onto one of the rounds at of the chair, and connected bya cord or cable e with the catch. The cord or cable 6 extends through an aperture in the board 19 between the upright part of the bolt 0 and the leg, so that by pressing upon the upper side of the treadle the cord will draw the bolt against the spring (1 out of the notch in the ratch bar or spindle C.

If the seat is raised to its highest point, it cannot be withdrawn from the base unless the catch is pulled back, owing to the shape of the lowest groove or recess g in the spindle, which is not beveled and forms a stop for the catch 0. This prevents the spindle G from being entirely removed from the base when the chair is lifted and carried by means of the seat.

I also preferably provide the chair with a tray-board E, which not only serves to hold food and toys, but when connected in front of the child to the arms of the chair prevents the child from falling out.

The trayE is a board having curved edges and with a ledge it around the outer edge. One side of the tray is pivoted,by means of a screw or bolt i, to one of the arms F of the chair, so that it may swing outward away from the child. When swung around,it may be dropped to the position indicated by the broken lines in Fig. 2 of the drawingsviz., to a vertical position by the side of the seat. The arm of the chair is pivoted at its ends and turns with the tray. The opposite side of the tray is held to the other arm,when de- ,sired, by means of a springclasp on the lower side of the tray, which clasp enters a recess in the arm is. In order to release the free end of the tray from the arm, it should be raised slightly before it is turned outward. Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a nursery-chair, the combination of the base, a seat-supporting spindle having angu- IOO 1:11 annular teeth, each havinga right-angled passing through an aperture in said crossunder side and a do 11Wmdly-inelined upper piece, substantially as described and shown. 10 side, and an annular groove, g, at the lower In testimony whereof I have hereunto end of the spindle, a cross-piece 011 the base, signed my name.
