SHEET-METAL STOVE LlEG.

Application filed. February 1'7, 1927. Serial No. 169,091.

This invention relates to im rovements in sheet metal stove legs being a apted for use with either gas or oil cook stoves.

The primary object of the invention is the provision of a leg composed of a single piece of sheet metal.

A further obi'ect of the invention is the' provision of a eg composed from a single piece of sheet metal constructed in a manner whereby a light weight metal can be utilized and at the same time provide a leg which is strong and durable in use.

Another object of the invention is the provision of a leg with novel means for removably or conveniently and easily interlocking or connecting it to the stove body and removing it therefrom.

A further object of the invention is the provision of a. sheet metal stove leg made from a single piece of material and constructed in a manner whereby the upper end of the leg is of double thickness and strength. Other novel features of construction and improved results of the invention will be 2 pointed out in the following description and accompan ing drawings.

A sheet metal leg for stoves is desirable in that its manufacturing expense is considerably less than a cast leg but its construction must be such that'an equal amount of strength and durability is built into the sheet metal leg as is found in the cast le It is also highly desirable that the leg e composed of a single piece of material so as to eliminate additional parts which must be secured to the legebefore it is completed. The manufacture and attachment of these additional parts increases the cost of production which is not at all desirable- Having the above facts in mind, the present invention has been conceived.

'while the wing portion Referring to the drawings, the improved leg is designated A, the stove body B, and the stove baseO.

The leg is formed from a single piece of sheet metal of the shape and form appearing in Figure 2 of the drawings, and designated as D. A specific description of the leg blank will be given hereinafter.

The completed leg is angular in form, having a front wall or face 1 and a side wall or face 2. At their lower ends these front and side walls taper slightly outwardly asat 3 and terminate in a short vertical wall or foot portion 4. This vertical wall 4 is bent to form the horizontal foot or base 5 at the extreme lower end of the leg.

Adjacent their upper ends the front and side walls of the leg flare outwardly as at 6 to form elongated upper edges 7.

The top of the leg is formed by bending the wing portions X and Y (see Figure 2), downwardly and inwardly at right angles to their respective walls. It will be seen that the wing portion Y underlies the wing p'ortion X which necessitates an off or down set 8 adjacent the upper front edge 7 of the leg top.

It will be seen that the Wing portion X is composed of two winlg portions 9 and 10 is composed of two wing portions 9 and 10 which are separated by a groove or channel 11.

By reference to Figure 5 of the drawings it will be seen that the two portions X and Y constitute the top of the leg which is designated generally in this figure of the drawing by the numeral 12. To form the top of the leg,' the wing portions X and Y are bent on the dotted line 13 of Figure 2. The supplemental wings 9, 10, 10 and 9 are in turn bent'upon the dotted lines 14, 15, 16 andl? to form the upstanding ears 18 and 19 appearing at the inner edge of the top 12 in Figure 5 of the drawings. The two slots or grooves 11 register with one another when the main wings X and Y are bent to proper position, the groove or slot 11 appearing under that numeral in the several figuresof thedrawings.

To add strength and rigidity as well as appearance to the leg, the blank is bent longitudinally of the leg on the dotted lines 20 and'21 to form the beads or edges 22 appearing in Figures-3 and'5 of the drawings.

The base or foot 5 of the leg is formed by bending the lower edge of the leg transversely on the line 23.

The slot or space 24; between the wings X and Y is slightly apparent in Figure 5 of the drawing. This clearance between the wings is necessary to accomplish the proper shaping of the le s.

It will be seen diet the supplemental wing portions 9 and 10 are slightly wider or greater in area than the supplemental wing portions 9 and 10. This is made necessary for the reason that the wing portion Y underlies the wing portion X and to permit the several members to properly register, this additional size must be allowed to compensate for the offset 8 and the fact that the wing portion Y completely surrounds the wing portion X.

The stove base C is of a construction in more or less common use and comprises an L angle iron, the vertical leg 25 of the L extending in a parallel line with the side and front faces of the leg while the horizontal le 26 thereof is of a width similar to the width or depth of the stove leg top 12. This horizontal leg rests upon the leg top 12 and its inner edge 27 engages the turned lips 18 and 19 of the leg top. At its inner corner the stove base 1s provided with a squared cut-out portion 28 adapted to register with the groove or slot 11. A headed bolt 29 passes through this squared opening and the groove. Below the bolt head 30, the bolt is provided with a squared or nutlike portion 31 which is of a size to properly engage the squared opening 28 and thus prevent the rotation of the bolt. A winged nut 32 is provided for the bolt 29 and clamps against the under face of the stove top, and in conjunction with the lips 18 and 19 firmly locking the stove base in position upon the upper end or top of the leg.

Attention is directed to the fact that an elongated rectangular shaped dished out or depressed portion 33 is provided at each side of the groove 11. By reason of this construction a reinforcement and stiffening for the leg is had at the point. where the stove base is bolted to the leg. The actual weight of the stove and the support of the stove base is at the edges which prevents the leg from rocking. It has been found that if this depressed ortion is eliminated and the upper end of t e leg left fiat, that the stove base has a tendency to rock when the clamping bolt is tightened. i

It will be readily understood that the stove B is suitably fastened to thebas'e O in the conventional manner.

In the completed Ie the wing portions X and Y are spot wel ed together to assure and guard against any movement between them.

From the foregoing it will be seenthat there is provided a sheet metal leg which in appearance is similar to a cast leg and that by reason of its particular construction, it is equally as strong and durable.

The advantages of a sheet metal leg made in one piece with an upper end of double strength and thickness will be readily apparent to those skilled in the art.

Particular attention is directed to the dished or depressed portion 33 as this construction assures the stove base against rocking on the upper end of the stove leg. It will be seen by reference to Figure 3 of the drawings that the outer edge of thestove' base C engages the upper edge of end 7 of the leg while the inner edge of the base engages the rear edge of the leg top 12.

By reason of the leg flanges 22, a le composed of a sheet material of light welght is made stronger than one of much heavier material should the heavier material be formed into a leg without such a flange.

This flange materially reinforces and strengthens the leg.
