'i a To (all "am-a may concerns- I Be it known thatI, vDan'mnl l'. QEAI Q'Of New L isbon lll thet-ount-y of Qtsego and in the Staterof bewlork, have invented certain new and useful Intat angle to a line passing seat, as is liereinaftensct forth. i a

It also consists in aring or hoop, formed of suitahis one or metal rod, placed around and connected Letters TIetent li e. 105,515, dated July 1.9,15l0. V

L The Schedule referred to in these Lettem f'atent and making par: of the same provements in Chairs; and do hereby declare that the following is a full, clear, and exact description thereof, reference licnighad to' the accompanying drawing inaking a part ot'this specification, in whieh F1gi11*e 1 is a side elevation ot'a chair, provided with niyimprored legs, andp, o

Figure 2 isa likeview of a stool fora swirel-clniir, showing a modification in the form of the legs attheir pomts of attachment to the seat.

Letters of like name and lii'nd'refer to like parts in each of the figures. 4 l H The object of my inrentic-nis to provide chair-legs that shall be sntiiciently elastic to insure a hearing for each upon the floor, regardless of-a-nyordinary nuevenness of thesan'ie and a p I 7 It consists principally in a chair-leg constructed of metal rods or wire, and. provided with two or more a spiral cods,hav1ngtheir axis placed at, or, near a'right radially from the center of the with the legs between their lower ends and the. seat,

1 asis hereinafter shown. i

In the annexed drawing-- p :A represents the seat of anonlinarychair, which rests upon and is supported hy the legs 13, constructed of; WW6 m the following manner ,Thewire is bent nearly together-at its center, in

the form shown at b, after which each half is bent spirally one and one hali' times, so as to form two cells, 0, the axes of which areeoincident, while their innerfiicesare parallel with and at a short distance, from-each other. From the coils O the wires extend upward midway to tlieehair-seat, where, by a single turn of each, two other coils, D, are formed upon the oppositeor onterside of the leg from the first coil 0.

the spiral fcoils, any degreeof'rigidity" A thirdset of coils, E, is formed upon the inner side of the leg near the seat A, alter which the ends of the wire pass directly upward into the same, as in he. 2, or'are crossed and enter said seat diagonallgas shown in fig. 1'.

Passing horizontally around the legs B, and through the central coils I), is a metal ring or hoop, 1!, which confines said legs at their center, and prevents, *attliat 7 point, any radial movement of the same.

7 As thus constructed and applied, downward pressure uponth'e seat will cause the lower ends of the legs to spring outward, and their upper ends-to spring slightly inward, until each has a firm bearinguponthe floor,

after which anyincreasc of saidpressnre n 1 illciuse;

snidlegs to further change their original sl apc,g,u til such pressure is'e'qualized by their increasedgteusioif; iiinheroi; lastieity By varying theisize of the wire and'th may he ohtaiued-for the legs, so as to adapt them to: the weight to he sustained.

The advantages possessed by this construction of the legs are, that being elastic, each leg is sure to iiud a bearing upon the floor, while the same property rend-e crs the chair more easy and comfortable to the occnpant. 1 i r 1 Having thus fully set forth the nature and merits of my invention, Q What I claim as new, is-- X chair-leg constructed of parallel metal rods or;- wire, each provided with two or more spiral coils, sub-f stantiall y as shown and for the purpose specified.

I Also, in combination with chair-legs constrneted ofwire, as described, a circular metal ring or hoop for confining the same in position radially, substantially as and for the purpose set forth.

In testimony that I claim theforegoing, I "have hereunto'set my hand thisfZSth day ot'Jline, 1870. I i bANll llrEj'll lAL;
