3 Claims.

"This invention relates to'improvement in rements where space is limited, etc.

One of the main objects of the present invention is to provide a superior revolving chair so lconstructed and arranged that the required parts thereof may be adjusted to enable the user to observe her person While sitting in it by merely lifiting a portion of thelback of the chair and thus bring a concealedmake-up mirror to a usable position.

Another object of the present invention is to provide a superior revolving chair, so constructed `and arranged that the required parts thereof may be adjusted to enable the user to observe herself in a favored lighting condition by merely revolving the chair, thus bringing the make-up mirror part of my improved revolving chair to the direction of the light source of the room.

A further object of the present invention is to provide a superior revolving chair which includes a rotating seat together with a concealed vanity compartmentl as part of the back construction of the `chair and adapted to be within 4the reach ofthe sitter when used as a make-up device by bringing the concealed mirror to the useful position. t l

Still another object of my invention 1s to pro- :vide a superior revolving chair mechanism or device to which a set of chair legs can be bolted without the use of glue or nails thus making it .possible for a sturdy and smoothly running revolving chair.

Still another object of my invention 1s to provide a better method of concealing the usual gap,

between the revolving seat and the stationary legs,

which is part ofthe old type of revolving chair construction, so that a better looking 4and more practical revolving chair can be made.

Other objects and advantages will become ap- ;parent from the specification, taken in con- `nection with the accompanying drawing,` wherein .one embodiment ofthe invention is illustrated.

In the drawing Fig. l is a perspective view of one form of my revolving chair combined with a vanity for boudoir or living-room use; -I Fig. 2 isa transverse sectional view taken on Fig. 3 is an exploded perspective view of the revolving mechanism; Y I

Fig. 4 is a partial verticalvsectional view taken on the une 4-4 on Fig. 3; and

Fig. 5 is a modified method of attaching achair leg to the base member. o

Referring now to the said drawing,l it will be seen thatthe embodiment of the invention illustrated consists of a main support member I0 having a central hub portion Il from Which radially extend substantially in one plane aplurality of arms I2, there being four such arms shown. H p y -As shown, each armi2 is formed by two paral- V lel flanges `I2a and I2b and spaced inwardly from its outer extremityV is a depending web I2C. `In

this manner I have providedeach arm I2 with a recess I3,to receive the ends'oi` the'legs I 4. To obtain a more .compactmethod of shipping and also ease of assembly, I provide the Webs I2C with open slots |2d to receive the Shanks of flat- `head screws I5 inserted through holes Ita adjacent the upper ends of the legs I4 and thus retain the legs in these recesses by fastening means, such as the nuts I5a. The fact that the upper ends of the legs I4 `are so supported in a recess bearing on three sides thereof and having a top abutment wall I2dspanning the two parallel flanges I 2a and I2b provides` a large factor of rigidity.

In Fig. 5 I have illustrated a modication of the means for securing the leg in its recess or socket. .Due to atmospheric conditions in certain sections, the bolt and nutl clamping arrangement ofthe form previously described may become loosened and-thus allow the leg to drop free of the recess .if the chairis lifted from the oor lbefore retightening the bolt. To prevent this I provide an additional screw I5!! which passes through a hole in the top Wall I2d and is threadedly engaged in the leg asis clearly shown in Fig. 5. I

Centrally located in the hub portion II of the support member I0 I provide a bore I6 to receive the shaft I1 fixedly mounted in a central hub portion. 18a of a spider I8 having three radial arms `integral therewith. The lower face of the spider arm hub I8a is provided with a circular groove |81)l and in conjunction with a similar circular groove Hain the upper face of the .hub informs a raceway for the antifriction bearing members I9. I

1 'The seat member 20 comprising the plate-like part 20a; which may be of wood padded with "material 20h and covered with fabric 20c, is

fastened to the spider I8 by means such as the screws 2| passing through holes I8c adjacent to the outer ends of the spider arms. Fixedly attached to the seat is aback rest member 22 and the complete assembly of the seat and back is thus mounted for swivel action by means of the shaft l1- and anti-friction bearing I9 on the main support lmember IIJ, and is retained from displacement one from the other by means of the washer 23 bearing on the under side of the hub portion Il and the screw 23 threadedly engaged in the lower end of the shaft l1.

I have provided the revolving seat member with a downwardly projecting annular ange 25 for the dual purpose of preventing any entanglement of garments or the like with the swivel mechanism, and also to enhance the beauty of the complete chair.

This flange 2'5 is fastened to the seat member 20a by means of the angle clips 26 and in order to maintain the outside diameter of this flange 25 relatively the same as the diametric distance between the outer faces of the legs M, I have cut back the upper ends of the legs as shown at Mb an amount approximating the thickness of the flange 25. Upholstery fabric 25a 'mayA be applied as shown. l

The back rest 22 I have made further functionally useful by providing therein a compartment 26 in the following manner: the rigid back member 21 is fastened to the vseat member 20a, by angle clips (not shown), or any manner well known in the art, and supports approximately midway its heighth a shelf or platform 28 which forms the base of the compartment 26; ett-they top edge of the back panel 21 I hingedly attach at 29 an angular member 30 which forms the top 3| and the front 32 of the compartment 26. Padding material 33 with upholstery fabric 34 finishes the lower portion of the back rest, while padding material 35 and upholstery material 36 applied to the angular member 3l) completes the finishes appearance and results in symmetry of the completed article.

The compartment cover indicated as a unit by the numeral 31 rests in its closed position, as shown by full lines in Fig. 2, by gravity and when swung to its open position, indicated by dotted lines also in Fig. 2, is retained in upright position by the abutting surfaces indicated at 39.

Mounted on the inner surface of the members 32 I provide a mirror 40 which, when in the open or dotted line position of Fig. 2, becomes accessible for reflective use.

Thus when the compartment 2S is closed. by the cover 31,l the whole chair will appear as a regular comfortable side chair to be used in any living-room or boudoir. However, when the user wishes to make herself up, or should he wish to shave, the cover may be swung o pen exposing the compartment and its contents and bringing the concealed mirror 40 into eye level and, in the meantime, swiveling the chair so that the direction of the light on his or her face would come from vthe proper angle, thus making it possible to have a device which will at all times, regardless of from which window the greatest light source is coming, or regardless of whereA the light bulbs of the room are located, afford the best illumination on the users face while he or she is sitting on the chair and going through the process of makeup or shaving.

The construction of the revolving mechanical unit and chair as shown in 'my application is also unique in that it vnot only provides'a foolproof mechanism, but it also introduces a sturdy base which is important when the upper portion of the chair is permitted to revolve. The bolting of the legs plays an' important part in keeping the chair continually sturdy for no gluing or nailing is a part of this construction. Furthermore, this type of construction not only makes a better looking revolving chair, but it also eliminates the rubbing and wear of the users clothes against the stationary railing of the old type of chair for in my invention the flange, which replaces the old stationary railing, rotates with the seat.

My improved revolving mechanism or device, as explained in this specification, is not only adapted for revolving chairs, but also can be used for revolving table bases and other rotating articles where substantial, smooth-running construction is essential.

As many changes could be made in the above construction and many apparently widely dilerent embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

What is claimed is:
