(Cl. S- 134) 8 Claims.

This invention relates generally to certain new and useful improvements in pedestals and, more particularly, to pedestals or bases for stools, chairs, and similar seating devices commonly employed at soda fountains, bars, counters, and the like.

Up to the present time, pedestals and stool bases of the type stated have conventionally been Such pedesand consequently the shipping cost is relatively high. In addition, castings of this type are rough and frequently surface-pitted, necessitating various expensive surface finishing operations before the casting can be plated, enameled, sprayed, or otherwise decoratively coated. Cast-iron stool bases of this character, furthermore, are frequently defective and a relatively large number of them must be rejected from each lot of castings. Finally, the completed castings are somewhat brittle and frequently crack, chip, or break when roughly handled by workmen during installation at the location of ultimate use, impeding the progress of they installation and interfering with its completion.

My invention hence has for its primary objects the provision of a unique and improved form of pedestal or stool base which is simple and economical in construction, which is extremely light in weight, which is tough, durable, and non-brittle, which may readily be adapted to a wide variety of external decorative designs at extremely low cost, which may be quickly and conventionally installed, and which is otherwise highly satisfactory in the performance of its stated functions.

And with the above and other objects in view, my invention resides in the novel features of form, construction, arrangement, and combination of parts presently described and pointed out in the claims.

In the accompanying drawings (2 sheets)- Figure 1 is a perspective view of a counter stool constructed-in accordance with and embodying my present invention;

Figure 2 is a vertical elevational view, partly broken away and in section, of the stool base of my invention;

Figure 5 is a fragmentary View, partly broken away and in section, of a modified form of stool base of my invention; and

Figure 6 is a fragmentary vertical sectional view of the modified form of stool base, taken approximately along the line 6 6, Figure 5.`

Referring now in more detail and by reference characters to the drawings, which illustrate practical embodiments of my present invention, A designates a stool base including an outer shell I pressed, drawn, or spun from relatively thin metal preferably capable of taking a high surface polish or such other suitable ornamental coating as may be desired and provided at its lower end with a diametrally enlarged outwardly flaring base flange or bell 2, which may have any suitable shape depending upon the decorativeshell I.

Pressed upon the upper projecting end of the tubular shell shaft 3, is an annular spacing collar 5 endwise supporting aconventional seatoperating cam 6, the steel shaft 3 being peened over around its upper projecting margin in the formation of a retaining lip 'I for holding the cam 6 securely in place, all as best seen in Figure 2 and for purposes presently fully appearing;

At its lower end, the tubular steel shaft 3 isnternally provided with a centrally bored collar 8 preferably secured in place by a fillet weld 9 or other suitable means and welded or otherwise suitably mounted uponV the outer surface of the tubular shaft 3 adjacent its lower end, is a plurality or radially extending channelshaped foot members I0 projecting obliquely downwardly and being cut off in the provision of floor-engaging surfaces II, all of which 0bviously lie in a common plane at right angles to the longitudinal axis of the tubular steel shaft `3. In' this connection, it will also be noted that the length, angle of inclination, and size generf 1, holding the several parts securely together in a unitary structure. The stool base A may be installed substantially in the same manner as disclosed in my previously granted patent, No. 1,829,960, granted November 3, 1931, that is to say, a suitable stud I2 is embedded head down in the iioor F with a sufficient length of its threaded end or shank projecting upwardly to extend through the apertured collar 8. A suitably elongated socket wrench is inserted through the tubular shaft 3 and a retaining nut I3 is installed for clampingly securing the entire structure tightly upon the floor F.

Finally, as diagrammatically indicated in dotted lines in Figure 2, a suitably sized conventional stool swivel s is disposed within thev upper end of the s'teeel shaft 3 in endwise abutment upon the annular shoulder or bead b for rotatably supporting a conventional seat-tripod or spider S and upholstered seat B, all as best seen in Figures 1 and 2. K

It will, of course, be evident in this connection' that the tubular shaft 3, being fabricated of steel tubing, is extremely strong and yet comparatively light in weight. Similarly, the outer shell I may be fabricated of very light materials and, therefore, will lend itself to a wide variety of different decorative designs and finishes and will also be relatively light in weight. From this, it will be evident that stool bases constructed in accordance with my present invention will be,

inexpensive, durable, and light in overall weight. Thus, material savings, due to lower shipping costs, may be effected, and greater durability, low nishing and surfacing costs, and wide range of decorative design will be achieved.

I may also provide a modified' form of stool base A including an outer shell I' having a flaring bell portion 2 and a tubular steel shaft 3', all substantially identical with the corresponding parts of the previously described stool base A. Welded or otherwise secured upon the lower end of the shaft 3', is a spun or stamped steel basedisk I4 integrally including 'an upstanding peripheral flange I5 and a centrally disposed upstanding shaft-embracing collar IB. Spot-welded around lits peripheral margin to the upper face of the base-disk I4, is a conical or dished bracing member I'I centrally apertured for snug-fitting embracing engagement around the disk-collar I6 L and welded with the base-disk I4 to the shaft 3'. In this connection, it may be pointed out that the base-disk I4 and bracing member I'I are preferably sized and shaped for close-fitting concealed disposition Within the flaring bell portion or base flange 2' of the outer shell I', all as best seen in Figures 5 and 6.

It should be understood that changes and modifications in the form, construction, arrangement, and combination of the several parts of the pedestal may be made and substituted for those herein shown and described without departing from the nature and principle of my invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:
