' ADJUSTABLE ASE.-

A pplication filed-March 14, 1927. Serial No. 175,151

My invention relates to adjustable bases for floor lamps, smoking stands, coffee tables and the like, andparticularly to bases having an adjustable framework adapted to have superimposed thereon and to'have rigidly held therein a slab of onyx, marble or similar Ornamental member.

In floor lamps, smoking stands, andthe like, making use of such ornamental members as part of the bases thereof, it is necessary and desirable to have a. framework to hold such ornamental member in pl.ace, sup port same above the floor and also to support the upright standard or standards of the lamp, smoking stand or similar article in which suchbase is made use of. An ob ject of the invention is, therefore, to provide a neat, simple, ornamental and ineXpen siv e framework for this purpose. I

Another objectof the invention is to provide means on said base framework for readily adjustingsame to fit the particularj'size and shape of the ornamental member superimposed on said framework. In practice, it very diflicult to produce onyx. marble or similar ornamental substances in slabs of precisely uniform size and it is not unusual to find the slabsvarying slightly in size and shape, sothat where a non-adjustable base framework is used, the ornamental member isv not held rigidly in place, the fit is not a curate and the job asv a whole is unsatis factory. \Vith applicants device, however, a. perfect lit is produced in' every instance, since the frai'nework'is accurately adjusted to the particular size and shape of the slab held therein, and it is possible to form integral with the legs of the framework laterally extending ornamental fingers, which lie adjacent the edges of the ornamental slab and serve as clamping members to hold the slab rigidly in place, as well as serving for additional ornamentation. This feature has hitherto been impracticable due to the variance in size and shape of the slabs used, the expense of machining, etc.

Other objects and features of the inven- Lion will appear from the following description and drawing illustrating an embodiment of the invention, merely for the purpose of affording an understanding of the invention and not forlimitation thereof.

In said drawing, Fig. 1 is a perspective VlOW of an adjustable base of my invention, adapted for a smoking stand, floorlamp and the like. Fig. 2 is a cross-sectional view of p irt of the base, showingthe mode of attachment of the leg members to the base on the line 33, Fig. 2.

,The device comprises a spider frame or plate 10, havingradial extensions or arms 12. 12 and leg members 14, 14 adjustably attached to said arms 12, the device being supported a short distance above thetloor by downward extensionsl6, 16 on leg members 14, 14. A slab of onyx, marble or similar ornamental member 18, indicated, in dotted lines in Fig. 1, is adapted to be superimposed on the device and be rigidly held in place thereon between the upward extensions or fingers 20, 20 on leg members 14, 14.

To accommodate the device to ornamental members of varying sizes and shapes, means are provided for making the leg members 14 adjustable with'respect to the arms 12. Said arms 12 are provided in their upper surfaces frame, and Fig. 3 is a cross-sectional view with grooves or channels 22, preferably ta per-sided, extending longitudinally thereof, and in said channels 22 and extending in the same direction therewith are elongated slots 24. The leg members 14 are provided on their under sides with longitudinal ribs or tongues 26, also preferably taper-sided, adapted to register with. and slide in the channels 22 of arms12. In this way there isobviatedthe possibility of side-play between theleg members 14 and the arms 12, and there is a tight fit of the one in the other in any adjusted position. Any fastening means, such as screws 28, may be passed through the 'apei'turesfiO' provided in the leg members 14, and through the elongated slots.

24 in the arms 12, to hold the two together in any adjusted position. To provide greater adjustability betweenv the leg members 14 and the arms 12, additional apertures may be provided in the leg members 14, such as 31. 31.

Plate 10 is provided with a tapped aperture 32 in its center, to receive the upright standard of the floor lamp, smoking stand or other article of which the base forms a part, which upright standard passes through an aperture in the center of the ornamental member 18, and is screwed into said aperture 32.

The arms 12 on plate 10 may be of any size or shape, and although four such arms are shown in. Fig. 1, it is to be understood ornamental design and may be of an that a greater or lesser number may be used, if desired, depending on the size and sha of the ornamental member adapted to e superimposed on the device, and depending also onthe ornamental efl'ects desired to be obtained.

The upwardly extending fingers 20 on the leg members 14, which lie closelyadjacent the edges of the ornamental member 18 and serve to hold same I'i idly in place on the device, may be of any esirable size or shape required to harmonize wit' the ornamental member 18 and with other parts of the article of which the'base forms a part. 7

To assemble the base, the leg members 14 are loosely screwed to the arms 12 of the plate 10. The slab 18 is placed on the framework 10 and the leg members 1e drawn up closely against the edges of slab 18 sothat the upwardly extending fingers 20 of the leg members 14 tightly clamp the slab 18, and then the screws 28 are tightened. The base when so assembled makes a perfect fit and presents a pleasant appearance, and there is no play of any kind.

between the parts.

In one-piece base frames now in common use, it is necessary to gild or plate the entire device, although but a few small parts are visible to the eye when the base is actually assembled on an article, such as a floor lamp, smoking stand or the like. With a plicants device, however, there is a su stantial saving in this direction, since the only parts of the base framework visible to the eye being a few small parts of the leg members, it is only necessary to plate or gild the leg members 14. V 1

Vith applicants construction, the parts can be made in a simple casting operation much quicker and at substantially lower 1 prices as compared to base framework constructions now in common use. The device is easy to assemble and take down, it has the desired adjustability to enable each article turned out to be accurately assembled and fitted, and allthe ornamental slabs can be made use of without any waste, re-

gar'dless of slight variations in size or shape, and thedevioe enables a higher degree of ornamentation tobelseoured.

Changes and modifications may be resorted to within the scope of my claims, without departing from my invention.

I claim:

1. A base frame of the class described, comprising a central plate provided with radially extending arms hav ng longitudinally extending rooves at their upper sides longitudinally: extending grooveswith inclined walls opening along the upper sides of the arms and with elongated slots formed in the bottom wall of said grooves, legs provided with lon itudinally extending tongues with inclined walls adapted to be slidably received in said grooves, fastening members extending throu b said slots and engaging said legs to hol and clamp same rigidly in adjusted"position with respect to said arms, and upward and downward extensionson the leg members the latter serving as feet to sup ort the frame and members carried there y and the former serving to engage a block or other member supported upon the leg members and to clamp same 1n place when the leg members are forced inwardly toward the central plate and fastened in such relation.

In testimony whereof I have signed my name hereto.
