Oct. 25, 1938. w. R. MCGIOWEN CHAIR Filed May 29, 1937 Patented Oct. 25, 1938 UNITED. STATES PATENT OFFICE CHAIR William R. McGowen, Pittsburgh, Pa., assignor to The McKay Company, Pittsburgh, Pa., a corporation oi Pennsylvania;

Application May 29, 1937, Serial No. 145,583

3 Claims. (01. 155-194) thereof; Fig. 3 is a bottom plan view, and Fig. 4 is a sectional view taken on the line IVIV of Fig. 3.

The leg structure is here shown as formed of two tubes each bentso as to form a front leg 5, a rear leg 6 and a seat bar portion 7. Each leg unit may be formed ofa single piece or of a plurality of pieces connected in unitary relation, and

may be formed of material other than metal tubes.

An important feature of my invention involves the bending inwardly of the seat bar portions 1,

as shown more clearly in Figs. 2 and 3. These inwardly bent seat bar portions are secured by screws or bolts 8 and 9 to a board or plate III that is covered with a pad or upholstering H. Open framework or other types of seats could, of course,

be substituted for the board ill. By reason of the angularity or lateral spread of the seat bars 1 and theirconnection to the seat board, it will be seen that the legs are thereby strongly braced and held in rigid relationship to the seat and to eachother, especially if the seat 3 bars are deflected inwardly to nearly the center of the seat board, as shown. This construction is or further utility in that the angular seat bar portions 1 constitutebase extensions or flanges for each of the legs 5 and 6, which prevent tilting of the legs and serve to support the tubular or other narrow bar stock material against transverse rocking movements whereby the securing devices 8 and 9 are not subjected to severe bending strains.

Back bars I 2 may also be formed of tubular stock, and are welded at l3 to the seat bar portions 1. The upper ends of the back bars l2 are 5 flattened somewhat and connected to a back member l4 by screws. The ends of the bars l2 that are welded to the bar portions 1 have extended contact therewith, thereby serving to brace the bar portions 1 against transverse rocking 10 movements.

I claim as my invention: ,1. A chair comprising a seat member and a pair of leg members disposed adjacent to opposite edges of the seat, each having two legs connected 15 at their upper ends by integral transverse seat bar portions which are deflected laterally at points intermediate the legs and extend from the edges of the seat member to points more closely adjacent to the seat center than to the edges of the seat, to form base-like extensions to support the legs against tilting relative to said seat; and se-' cured to the seat member.

2. A chair comprising a seat member, a pair of leg members respectively disposed adjacent to opposite edges of the seat and each member having two legs formed with a transverse seat bar portion',.the two seat bar portions being bent in opposite directions and having flat contact throughout their lengths with the bottom of the seat, and means for securing the said seat bar portions to the seat.

3. A chair comprising a seat member, a pair of leg members respectively disposed adjacent to opposite edges of the seat and each member hav- 5 ing two legs formed with a transverse seat bar portiorrthe two. seat bar portions being bent in opposite directions, in a plane parallel to the underside of the seat, and means for securing the seat bar portions to the underside of the seat, adjacent to the inner and outer portions of the seat bar portions. 5
