SUPPORTING BASE Filed Feb. 17, y1928 Patented Jan.. 6, 1931 '..crs eine eHARLn-s J. Tnnvnns, oF Ponfrwnsninefron, wisconsin, Assienon To artsen MANU'- -FACTURING co., or :roary wnsnine'ron, wisconsin surron'rlnennsn l i Application led February 17,1928'. ISerial 310.254,997.

' This invention relates to supporting bases. which lies in a horizontal 'plane andy rests Objects of this invention are to provide al novel form of supporting base which, although adapted for numerous other uses, is

particularly adapted for supporting chairs, and which is so constructed that spreading of the legs cannot occur, but' instead of whichthe legs are securely braced against spreading at both their upper and lower portions, la; and which is provided with a load receiving member which may be a spindle receiving member, and which is Vsuitably carried by members secured tothe legs in a rigid and y permanent manner. i; f Embodiments ofthe invention are shown in the accompanying drawings in which:

Figure l isa view partly in section of the base.

Figure 2 is a sectional view on the line 2-2 of Figur'e'l.

Referring tothe drawings it will be seen that the base is composed of a plurality of legs having straight portion 1 extending downwardly and slightly divergent and curved and extending outwardly to provide curved supporting bottom portions 2. A braced spider in the form of a metal plate 3 is positioned between the legs. adjacent the bottom and is provided with a plurality of 2r; downwardly extending ears 4. rlhese ears are cuiWed to ft the curved bottom portions of the legs as shown in Figure 1 and are apertured and countersunk or depressed for the reception of screws or other fastening means :n: 5, which extend therethrough and into the le s.

second plate 6 is positioned between the legs as shownin Figure 1 and is provided with a plurality of downwardly extending 4D apertured ears 7, these lears contacting with the inner surfaces of the legs and receiving bolts 8 whose heads are preferably inset on the outer side of the legs. These bolts or screws preferably are provided with washers 9 as shown in Figure 1. The plate 6 has its upper face disposed in a horizontal plane and is apertured for the reception of the `lower end of the internally threaded spindle receiving sleeve l0. This sleeve is provided 5C- with an annular ange 11, the lower face of upon the plate 6. The liange 1l is preferably disposedA at a point adjacent the lower end of the sleeve 10. The plate 5, it willvbe seen, isa load carrying as well as a braced plate. The upper portion of the spindle is provided with a substantially rectangular flange 12, which contactswith the underside of an aperturedplate 13. This plate 13 rests upon the top of the legs 1, and is provided with a plurality-of depressed or countersunk apertured portions through which attaching screws 14 extend.. Suchscrews project into the ends of the legs. The plate 13, it will be seen, securely holds the upper endvof the spindle receiving or load receiving sleeve 10. Any suitable means may be employed for preventing rotationof the spindle. It has been found convenient to make the iiange 12 rectangular in contour, so that it'bears flatly against the inner sides of the upper portions of the legs.

If desired, foot rest supporting portions l5 may be secured to the legs and may extend outwardly therefrom. n l

It is to be distinctly understood that while this invention has been described as particularly directed to a chair base, it nevertheless is not to be limited to such use as obviously it can be used as any type of support for furniture or other articles.

It will be seen that a very simple and attractive type of base has been provided, which is so constructed that the legs are rigidly held against spreadingboth at their upper and lower portions.

It will be seen further that the device is simple to make and is of sturdy construction.

Although the invention has been described in considerable detail, such description is intended as illustrative rather than limiting as the invention may be variously embodied and as the scope of such invention is to be determined as claimed.

I claim:

A supporting base comprising a plurality of legs having downwardly extending portions and outwardly curving lower supporting portions, a bracing plate having down- 2;` t 'i Y 1,788,133

turned and curved apertured ears contacting with the curved portions of said legs, securing means passing through the apertures in said ears and into said legs,a second plate spaced upwardly from said first plate, having a horizontally disposed upperV face and laterally projecting ears arranged i-n a substantially vertical plane, bolts passing trans versely through said ears and said second plate having an aperture therethrough',` a third plate provided With an aperture' and secured to the upper end of said legs.k anda spindle receiving sleeve projecting through 'the apertures in said second and third plates" and having a flange formed with a horizontally disposed lower face resting upon said second plate, said flange having itsouter edge spacedl from the innerV faces of the' legs, said sleeve havingr an upper rectangular flange bearing against the under side offsaid Ithird plate,' and its side faces bearing against .the inner faces of the upper endsof the '0p'- posed leg' members.
