(01. 311-109)- h permit'the upper edges of the uprights I and 2 This invention relates to improvements in metal table or bench 1egs, and a principal object of the inventionis to provide a tubular leg construction of generally improved characteristics.

vMore specifically, an object of the invention is to provide a leg construction of the stated'type of relatively great strength and durability and of low cost of production.

The invention further resides in certain structural details hereinafterset-forth and illustrated in the attached drawing in which: I

With reference to the drawing,- a fabricated metal table or bench leg structure made .in accordance'with my invention may comprise ,two rectangular tubular uprights I and 2 united at their tops by a cross bar 3 and adjacent their lower ends by a stringer 4. Each of the uprights .I and 2; is provided at the bottom ,with a foot support 5 adapted to provide a suitable extended bearing surface for contact with the supporting surface. In the present instance, the topcross bar. 3 takes the form of 'a metallicv T-section which is mounted in the upright position to afford an extended flatsurface at thetop of the .leg structure. The depending flange B of this ;cross bar occupies longitudinal slotsin the upper ends of theuprights I and Z, as shown inFig. 2, these slots preferably being of sufficient depth to toj-contact with the under surface of the transversevflange of the T-bar. The cross bar3 may be united with the tubular uprights I and 2 by welding at the joints.

The stringer. 4 preferably is rectangular tubular form of dimensions corresponding with the cross sectional dimensions of the uprights I and2. In the present instance, as

shown inFigs.-3 ;and 4, this stringer is of :the desired rectangular form but divided longitudi+ nally inthe lower wall as indicated at I in Fig. 3. The ends of the stringer I in the present instance abut the opposed faces of the uprights I and 2 and are secured to the uprights by welding. The weld, as indicated at 8 in; Figs. 3 and 4, is

of substantially made on the inside of the stringer 4, and in order p to provide for thisinterior welding, I form the under sides of the stringer 4 at each end with .anopening 9 giving access to the inner joints for the weldingv operation. The surfaces at the external joints are thus left unmarred by theweldring and an extremely. neat and desirable appearance afforded.

The preferred form of the foot 5 is. illustrated in Fig. 5 and the manner of its connection with theuprights I and 2 illustrated in Figs. 6 and 7. As shown in the drawing, the elevated mid sec- .tion I2 is divided intermediate its ends by parallelslots I3 ,which are so relatively positioned as toreceive the opposite side walls of the upright to whichthefoot is to be attached. The width of the midsection' 12 is such that theother pair of opposite walls of the upright may rest upon theupper surfaceof the flange-I I, so that that portion of the mid section II-between the slots I3 is entirely embraced within the lower end of the upright. With the upright so inserted in the slots I3, the foot 5 may be united to the upright by welding at the joints at the under side of the foot, asindi'catedat I4 inFigs. 6 and 7. The opposite end portions of the mid section I 2 which lie at opposite sides of the upright are provided with openings I5 for reception of bolts whereby the foot may be attached to the floor surface if desired. v i v .It willflloe apparent that the aforedescribed device is characterized by an extreme simplicity of form and assembly; and at the same time af fordsa structure of considerable strength and durability. That portion of the mid section I2 of the foot 5 whicl'l'lies within the upright constitutes in effect a strut preventing deformation of the sides of thetubular form. andthe parts reinforce each other to produce a substantially rigid structure. At the same time, the construction has a' highly ornamental appearance which is materially aided bythe fact that the welded joints both 'for the stringer 4 and the feet 5 are all located at the inner unexposed surfaces. I

. It will be apparent thatthere may beiconsidcatedat '24.

erable modification without departure from the invention. In the embodiment, for example, shown in Fig. 8, that portion of the elevated mid sectioni lz of the foot which in the embodiment illustrated in Fig. 5 occupies in assembly a position within the tubular upright, has been entirely eliminated. In this instance, as shown in Fig. 9, the upright fits neatly within the space designated by the reference numeral l6 in Fig. 8, and the foot and the leg are joined together by welding, as indicated at I! in Figs. 9 and 10. The lower edge of the uprightin this instance rests upon the top of the flange l I as in the preceding embodiment, but it will be apparent that the inner portions of this flange may be cut away so that 'the'lo'w'er edge of the upright may lie flush with'the lower surface of the flange H. In order toreinforce these walls of the upright which are engaged by the elevated portions of the foot, I may provide in the interior of the leg and secure thereto by welding a strut l8 extending between these walls.

1 In Fig. 11, I have illustrated a still further embodiment in which the elevated mid section "of the foot is made of sufiicient width to perfilit of an opening IQ of sufficient size to admit the upright l. -Following insertion of the lower end of the upright in this opening I9, the parts may be joined together by welding at the points indicated at 2| in Fig. 13.

In the modification disclosed in Figs. 14 and 15, the elevated mid section I2 of the foot is solid throughout, and two opposite walls of the upright are cut away to conform to the shape of this elevated mid section. The foot in this case ineffect fits within a recess in the lower end of the upright formed by these cut-out portions, and the upright andthe foot may then be united by welding 22 extending around the outer edges of the joints. In'order to avoid this welding on the outer surfaces of the assembly, I'may, as illus'trated in Figs. 16' and 17, form openings '23 in the lower portions of the elevated mid section 12 which abut the opposite side walls of the up- :right. Theseopenings give access for welding to the inner sides of the 'joints between thelower edges of the upright and the'fl'ange H, as indi- The external welded joints are thus avoided.

There may be'still further'modific'atiohs withbutdeparture from the invention.
