NURSERY-CHAIR.

SPECIFICATION forming part of Letters Patent No. 730,306, dated June 9, 1903.

Application filed March 18, 1903. Serial No. 148,413- (No model.) 7 7 T0 ml whom it may conoerm Be it known that LGEORGE H. SMITH, a citizen of the United States, residing at Baldwinsville, in the county of VVorcesterand State of,

lilassachusettshave invented certain new and useful Improvements in Chair Attachments; and Ido declare the following to be afull,clear, and exact description of the invention, such as will enable others skilled in the art-to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form apart of this specifica= tion.

This invention relates to new and useful improvements in folding-chairs adapted to be adjusted for use either as a rocking-chair or as a high chair by the simple manipulation of the mechanism, which will allow the chair to be lowered for use as a rocker or to be automatically locked in an adjusted position to afford a high chair.

The invention consists, further, in various details of construction and combinations of parts, which will be hereinafter fully described and then specifically, defined in the appended claim.

My invention is illustrated in the accompanying drawings, in which Figure l is a perspective view of my chair shown as adjusted for use as a high chair. Fig. 2 is a view showing the same lowered to a positionfor use as a rocker; and Fig. 3 is a sectional View through a portion of the chair, showing the locking means, saidview showing in dotted lines the notched lever in a raised position to allow the seat-supporting legs to be turned down into positions to form rockers. Fig. 4 is a detail perspective view of the locking mechanism.

Reference now being bad to the details of the drawings by letter, A designates a chairbottom having a suitable back and arms, and B B designate strips which are fastened to the lower ends of the posts that support the back and the postssupporting the forward part. Said strips B have ears 0, fastened to the faces thereof, and to the lower ends of said ears are pivoted the combination legs and rockers E E, which are utilized as legs when the device is adjusted as a high chair and rockers when the seat is lowered to aposition shown in Fig. 2 of the drawings. Pivotally connected to the combined legs and rockers E is a second pair of legs F, the upper ends of which when the same are thrown at their highest limit are adapted to contact with the under surfaces of the strips B adjacent to their rear ends. Pivotally connecting said combined rockersand legs F with the strips B are the links G,there beingone on each side, and adjacent to the'upper end of each of said links is a notched catch H, which is secured to a round I. Each end of said round is similarly connected to a notched catch, which is pivoted to a link G, and K designates a rod, one end of which 'is fastened to said round I and its other end bent to form a loop or handle K, the shank portion of said rod passing through a screw-eye L, fastened to the rear edge of the seat. A coil-spring N is mounted upon the shank portion of said rod and interposed between the round and said eye and is provided for the purpose of holdirig said round, with the notched catch members thereon, in such position as to automatically engage lugs M upon the plates M, which latter are fastened to the upper ends of the combined legs and rockers F, whereby as the seat is raised for use as a high chair it will be automatically locked in such adjusted posiiion. The linksG are so positioned that they will form stops to the upper movement of the combined legs and rockers F by coming in contact with a round Q,-which is mounted between the upper ends of said legs F.

In adjusting the device for use as a rocker the operator merely raises the rod K sufficiently to release the catches from said lugs, and the Weight of the superstructure of the chair will cause the legs to fold, forming rockers, as disclosed in Fig. 2 of the drawings.

Whilel have shown a particular construchaving a lug thereon positioned in the path of said hook and adapted to be engaged thereby to hold the chair in a raised position, as set forth.

.In testimony whereof I hereunto affix my signature in presence of two Witnesses.

GEORGE H. SMITH.
