To all whom it may concern:

Be it known that I,'JOHN H. PETROsKEY, a citizen of the United States of America, residing at Detroit; in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Metallic Chairs, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to. metal furniture and especially to chairs whose principal sup porting members are tubular, and are secured to each other and the chair body by certain forms of fastenmgs which insure ease and cheapness of construction and as? semblement. I

The invention consists in the matters hereand Tmore particularly pointed out in the ap endedclaims.

Referring to the rawings, Figure 1 is a view in pers ective of a chair embodying the features of the invention. Fig. 2 is a. view of the under side of a seat-ring. Fig. 3 is a view in section of the seat ring taken on or about line A'A of Fig. 2.

The chair, as shown in the drawings, has a seat-ring 1 of cast metal, substantially circular or oval in contour, although obviously it may be of any preferred and suitable form. The ring has an interior annular flange 2 to receive. a seat body 3 whose smoothly rounded margin 4 projects beyond the ring A pairof outwardly inclined half-sockets 5 inset from the front of the ring body are integrally secured thereon by divergent ribs 6, v

and receive a pair of tubular front legs 7 which are secured by U-shaped clips 8 com-.

p'leting the sockets and screws 9 passing, The peculiar divergent posi therethrough.

tions of these sockets permit the front legs -tobe curved outwardly below the seat to give rigidity and to add to the appearance of the chair wlthout interfering with the person using the chair. I

A pair of half sockets 10 are integrally formed on the back of the seat ring in proper osition to clear the margin of the seat body, orthe rear legs 11 and back 12 which are formed of a single piece of tubing bent into proper shape to add to the appearance and symmetry of the chair.

The legs are secured in the sockets by U- clips 13 whose marginsare notched or gained to interlock with tenons 14 on the socket edges, and are clamped thereinby screws 15 paralleto the adja- 17 beingsubstantially andbeing seated in cent rods of the bac back, to which it is centrallysecured by a screw 16, the dependent arms solidcsockets 18 integrally formed on the seat 7 ring below and outside of the seat-body margin. Corner braces 19 whose upper ends abut against the back and whose lower ends are secured to the ring below the seat margin and a suitable cross-brace 20 of appropriate design between the legs complete the chair. One of the features of the construction is the shielding of the joints between the back,

supports and seat ring by the seat body, so I that lodgment of-food or the like is not pos. sible, and so that the chair is especially adapted for use in restaurants and cafes, the flush seat and overhanging margin being readily wiped off and the back presenting smooth surface, to which dirt and the like does not cling. 7

Another feature is the ri of the back, the legs and bee and the back rods acting as a brace between the top'of the back and the extreme margin of the ring. y

Another and very important factor in holding the chair rigidly, 1s the interlocking of the rear leg or back clips with the sockets, so that the transverse strain on the outer ends of the screws is transmitted to the seat- -ring, and the screw cannot spring and does not tend to shear off.

' VVhatI claim. as my invention is 1. A chair having tubular metal supports and back, a seat ring, inset oblique half-sock ets integral with the ring, adapted to engage the front jecting half-sockets integral adapted to receive the rear supports and backs, clips securing the rear supports and back whose margins are interlocked with the margins of the said rear sockets against longitudinal displacement, a seat body in the ring whose margin projects beyond the ring, and corner and cross-braces secured to the chair supports and ring;

2-; A chair having tubular metal supports and back, an inwardly flanged seat ring, inset voblique half-sockets integral With the ring, clips therefor adapted to engage the clips therefor with the ring '80 id COIISt-I'llClJlQIl. being integral,-

supports, proring a erture, tubular front legswhose upper ends ie in said sockets, Uclips mating the sockets securing the front legs therein, screws passing through the clips and tubing engaging the ring sockets, dependent outwardly extending half-sockets formed integrally on lugs projecting from .the ringopp osite the inset sockets whose vertical mar ins are tenoned, tubular rear legs and back ying in said sockets, U-clips mating with the sockets whose margins are ained to interlock with the tenons of the soc et margin, screws passing through the clips and rearlegs enterin the seat ring, projecting full sockets forme inte ally on the ring between the back-sockets, ack tubing whose ends are secured in said sockets, a seat on the ring whose margin extends beyond the ring, and corner and cross-braces engaging the tubular members.

and seat ring; I 4,- Achair comprisin'gan inwardly flanged seat ring of metah oblique" halfsockets formed integrally with the ring inset'into the ring aperture, tubular front legs whose upper ends lie in said sockets, U-clips mating the sockets securing the front legs therein, screws passing through the clips and tubing engaging the ring sockets, dependent out: ward y extending half-sockets formed integrally on lugs projecting from the ring opposite the inset sockets whose Vertical mar ins are tenoned, a back and rear legs forme of a single piece of tubing bent to appropriate shape lying insaid sockets, U-clips mating with the sockets whose margins are ained to interlock with the tenons of the soc et margin, screws passing through the clips and rear legs entering the seat ring, projecting full sockets formed integrally on the ring between the back .sockets, back tubing bent between its ends to liebetween and corre-- spond to the upper ortio'n of the backto which it is tangentia ly secured at its center point by a screw whose ends are secured in said sockets, a' seat on the ring whose margin extends beyond the ring, and corner and 1 cross-braces engaging the tubular member and seat-ring, and screws securing the ends of the back tubin in the full sockets.

In testimony w ereof I affix my signature in presenceof two witnesses."
