Application filed June 25, 1925.. serial n. 39,427;

This invention relates to pedestals for furniture, such as school chairs in which the chair seat is carried at the upper end of a spindle telescopically related to the pedestal and arrangedto be clamped thereto to pre-v which application the present application is a division. It should be evident, however, that the. subject matter of the present application might be used in connection with pedestals otherwise formed. d

When the pedestal is cast .in the usual manher it is liable to be broken at its upper end it the screw connnonly employed to hold the chair spindle in its proper vertical position in the pedestal set up too tightly. In order to receive the spindle also it has been the usual practice to cast integral with the pedestal a pair of lugs having tapered inner faces against which the spindle is urged by the tightening bolt. This has been done by the use of a core but if the core is not properly in the mold these lugs are not properly related in the finished casting. As the taper is very slight, being approximately two degrees, the core must. be set very accurately to produce the desired result.

According to the present invention a hole is made laterally through one side at the upper end of thepedestal, which is preferably formed as a hollow pillar of sheet metal, and within this pedestal portion or section is fixed as by spot welding a socket member provided with an internally threaded boss portion extending out through this hole, this boss portion receiving the bolt, the inner end of which engages the spindle. Also within this top section opposite to the bolt may be fixed a U shaped frame member having a V slot cut therein to form a air of spaced angle edges above and below t e axis of the securing bolt which form two spaced bearings for the chair spindle, the bolt itself forming a third bearing on the opposite side of the spindle between the two.

For a more complete understanding of this invention reference may be had to the accompanying drawings in which Figure 1 is an elevation of the pedestal.

Figure 2, is a central vertical section through the pedestal showing separated the various horizontal sheet metal sections from which the pedestal isbuilt up.

Figure 3 is a top plan of the upper pedestal section.

Figure. 4 is a perspective of an abutment against which the spindle is clamped.

Referring more particularly to Figure 2 of the drawings, the pedestal may be formed up from three sheet metal pedestal sections 1, 2 and 3, the base section 1 being pressed to shape and the sections 2 and 3 bein swaged from pieces of tubing to tapered form, or otherwise formed, preferably from sheet material. These parts may be electrically welded together along horizontal planes as disclosed in my prior application for patent hereinbefore referred to. i i i The upper end of the section 3 may be swaged or formed inwardly to form a substantially flat top as at 12 which may be perforated as shown at 13 so that the spindle] 11 of the chair or other piece offurniture to be supported may slide vertically within the pedestal.

In order to support this spindle and to fix it at any height desired, spindle guidingand retaining means are shown as carried on the inner face of the section 3. One of these members comprises a block 15 having a boss 16 which projects through an openin 17 through the side of the upper section 3. %his boss 16 is perforated and internally threaded as at 18 for the reception of the usual securing bolt 180 (Figure 1) which passesthrough thisthreaded opening so that its inner end may bear against the side face of the spindle. This block 14 may be fixed in position with in the section 3 by any suitable means preferably being spot welded at two or more points thereto, one of such points being indicated at 19. i i

At the opposite side of this section is posi tioned a member to take the thrust of the spindle thereagainst due to the pressure exerted thereon by the securing bolt. As shown best in Figure 4, this member comprises a substantially U shaped plate 20 having its flanges 21 spaced vertically and provided with projections 22 whici may be passed through holes 23 through the wall of the upper section 3 substantially opposite to the block 15, these portions 22 then being riveted over the outer face of the section 3 to retain the member 20 in position. Extending vertically across this member 20 is a V shaped groove or slot 25 which is formed slightly inclined through the web thereof, for example, two degrees from the vertical when the pedestal is positioned on a horizontal surface. The slot 25' provides a pair of spared edge portions 26 running vertically, and spaced horizontally disposed angular edges 27 in the flanges 21 against which the spindle engages, these portions 27 forming spaced bearing portions on one side of the spindle while the bolt passing through the block 15 engages the opposite side of the spindle between these portions.

Having thus described an embodiment of this invention, it will be evident to those skilled in the art that various changes and modifications might be made therein without departing from its spirit or scope as defined by the appended claims.

I claim:

1. In a furniture pedestal, a hollow pillar having a perforation at its upper end to receive a spindle, a U shaped member having its flanges spaced vertically within said pillar and fixed at their ends to said pillar, said member being vertically slotted through its web and the base portions of said flanges V to present a pair of spaced horizontal edges joining the ends of said vertical edges and against which the spindle may bear, and means for pressing the spindle thereagainst. 2. In a furniture pedestal, a hollow pillar having a perforation at its upper end to receive a spindle, a U shaped member having its flanges spaced vertically within said pillar and fixed at their ends to said pillar, said member being vertically slotted through its web and the base portions of said flanges to present a pair of spaced horizontal edges joining the ends of said vertical edges and against which the spindle may bear, and means extending through the pedestal on the opposite side from said member for pressing the spindle thereagainst.

3. In' a furniture pedestal, a hollow pillar having a perforation at its upper end to receive a spindle, a U shaped member having its flanges spaced vertically within said pillar and fixed at their ends to said pillar, said member bein vertically slotted through its web and the ase portions of said flanges to present a pair of spaced horizontal edges joining the ends of said vertical edges and against which the spindle may bear, and means for pressing the spindle thereagainst, the walls of said slot being slightly inclined outwardly and upwardly.

4. In a furniture pedestal, a hollow pillar having a perforation at its upper end to receive a spindle, a U shaped member having its flan es spaced vertically within said pillar an fixed at their ends 'to said pillar, said member being vertically slotted through its web and the base portions of said flanges to present a pair of spaced horizontal edges joining the ends of said vertical edges and against which the spindle may bear, and means extendin the opposite pressing the spindle thereagainst, the walls of said slot being slightly inclined outwardly and upwardl 5. A spindle receiving portion of a furniture pedestal which comprises a tubular portion with a lateral hole therein, a block within said tubular portion having a perforated boss projecting through said lateral hole, said boss being adapted to receive there through a spindle retaining member, and a U shaped member within said portion and opposite to said block and having a slot therein presenting in the flanges of said U through the pedestal on e from said member for shaped member a pair of spaced supports a for the spindle against which the spindle may be held b said retaining member.

6. In a furniture pedestal a hollow pillar of relatively thin sheet metal having a lateral opening therethrough, and a block fixed within said pillar and havin a base engaging a ainst the inner surface of the pedestal an a threaded and perforated boss projecting through said opening to receive a spindle securing bolt therethrough.

7. In a furniture pedestal a hollow pillar of relatively thin sheet metal having a lateral opening therethrough and a block fixed within said pillar having a base portion engaging against the inner surface of the pillar and a boss within said opening perforated and threaded to receive a spindle securing bolt therethrough, and a pair of elements fixed within said pillar spaced apart vertically one above and one below said boss and against which the spindle bears by the thrust of said bolt thereon.

In testimony whereof I have aflixed my signature.

CHARLES A. BROWN.
