LEG AND SOCKET CONSTRUCTION.

Specification of Letters Patent.

Patented July 25, 1916.

To all whom it may concern:

Be it known that we, ERNST E. Prnrrnn and FRANK Prnrrrnncitizens of the United States, and residents of, respectively, Milwaukee, in the county of Milwaukee and State of lVisconsin, and Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Leg and Socket Construction, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention relates to improvements in leg and socket construction more particularly adapted for wash tubs, wash stands and other like purposes, for supporting said objects a convenient distance above the floor.

It is one of the objects of the present invention to provide a leg and socket construction which may be easily formed of rolled or drawn commercial metal in a very simple manner.

A further object of the invention is to provide a leg and socket construction in.

which the socket member may be permanently attached to the object to be supported and the leg may then be removably inserted in the socket.

A further object of the invention is to provide a leg and socket construction in which the socket member serves to reinforce the side and bottom portion of the receptacle to which it is attached.

A further object of the invention is to provide a leg and socket construction which is of simple construction, is strong and d11- rable and may be manufactured for a mini mum cost.

With the above and other objects in view the invention consists of the improved leg and socket construction and its parts and combinations as set forth in the claims and all equivalents thereof.

In the accompanying drawings in which the same reference characters indicate the same parts in all of the views: Figure 1 is a side view ofa portion of a tub provided with the improved leg and socket construction; Fig. 2 is a vertical sectional view thereof; Fig. 3 is a transverse sectional view taken on line 3-3 of Fig. 1; Fig. 4: is a side view of a tub provided with a modified form of leg and socket; Fig. 5 is a vertical sectional view thereof; Fig. 6 is a transverse sectional view taken on line 0-6 of Fig. l;

Fig. 7 is a side view of a portion of a tub provided with another modified form of leg and socket; Fig. 8 is a sectional view thereof; and Fig. 9 is a sectional detail view taken on line 99 of Fig. 7.

Referring to the drawing the numeral 10 indicates a metal washtub or other suitable receptacle to which is secured a number of the improved leg and sockets, usually three or four. The tub or like receptacle is of ordinary construction and is provided with circumferential side and

bottom corrugations

11 and 12 and with an annular bead 10 which projects below and outwardly from the lower edge of the tub. lVhile the improved legs and sockets may be of various cross sectional shapes, such as angles, channels, T-shapes, it is only thought necessary to show and describetwo or three of the preferred forms.

The invention contemplates forming the legs of commercial rolled or drawn metal cut to proper lengths and forming socket members to fit the different cross sectional shapes of the legs. In the first form shown the socket member 13 is constructed of a strip of sheet metal bent to form attaching side flanges 1d and a socket or opening 15 extending vertically therethrough of T-shape in cross section. In forming the socket and the side flanges let the side portions of the strip are folded over to form the said flanges of double thickness and are then bent and spaced from the back portion 16 to form the T-shape socket with the side edge portions 17 of the strip jointed together medially, longitudinally of the socket member by rivets 18. The back portion 16 of the socket member is corrugated as indicated by the numeral 19 for a portion of its length to offset the said portion from the tub a slight distance and the other parts are shaped to fit the tub or other receptacle. The back portion of said socket member is extended above and below the socketed part to provide additional attaching portions. The lower extension 20 is bent approximately at right angles to extend beneath the bottom portion of the tub and is slightly corrugated transversely to fit the corrugated bottom portion of the tub and the annular bead 10' thereof. The upper extension 21 is also transversely corrugated to fit the side corrugations of the tub and both the extensions and the main portion of the back are socurely fastened to the back by rivets 22 or other means.

A leg member 23 formedof a piece of commercial T-iron cut to length and slightly angled at a point 23 to incline the leg outwardly is provided with a stop projection in the form of an angled bar 2st which is riveted to the inner side of the leg member with the angled portion 24 projecting inwardly beneath the tub and bearing against the corrugated portion of the angular lower extension 20 of the socket member. In order to lock the leg within the socket a portion 25 of the stem of the T-shaped leg is bent over at right angles and provided with a threaded opening to receive a thumb screw 26. The thumb screw. 26 is threaded through said opening and impinges against the bent over portion of the socket member and securely locks the parts'together. The portion of the socket member which receives the bent over portion of the leg member is slotted and the' side portions 17 are omitted as indicated by the numeral 27 to accommodate said bent over portion.

In the form shown in Figs. 4, 5 and 6 the socket member is preferably formed of a strip of" metal in which the side; flanges 28 are of single thickness ofmetal and opposite interposed side portions 29 are folded over toward each other toform a socket to receive the side flanges 30 of the T-shaped leg 23 and to form a slot 31 to accommodate the stem portion 32 of said leg. In this form the leg is locked in position in the same manner before described and is furthermore provided with an additional looking screw bolt 26 which is threaded through a bent over portion 25 similar to the portion 25 but bent in the opposite direction.

The modified form shown in Figs. 7 8 and 9 provides for using a leg member formed of a flat bar 33 and the socket member 84 isbent similar-to the first mentioned form with the exceptionthat the space for accommodating the stem of the first mentioned leg member is omitted and the space or socket 35 formed is approximately rectangular in cross section. In this last mentioned form the locking thumb screw 36 is threaded through the leg member and its shoulder 86 clamps against the bent over metal on each side of the slot 27. In other respects the leg and socket member parts are the same as before described.

From the foregoing description it will be seen that the leg and socket construction is of simple form and is welladapted for the purpose desired and it will also be seen that the leg members may be easily removed if desired and the tubs used'in the ordinary manner.

What we claim as ourinvention is:

1. A leg and socket construction formed of commercial strip. metal, comprising a socket member formed of a strip of metal bent to form attaching side flanges and a socket extending therethrough of T-shape in cross section, and a leg member of T- shape in cross section fitting into said socket,
