JOSEPH S. WALTON, 015 LOS ANGELES, CALIFORNIA.

REVOLVING STOOL.

Application filed November 9, 1923. Serial No. 673,851.

To all whom it may concern Be it known that I, JOSEPH S. WALTON, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Revolving Stool, of which the following is a specification.

This invention relates to improvements in chair and more particularly to counter stools. Y

The primary object of the invention is to provide a stool having a revolving seat, and an improved swivel connection bet-ween the seat and base.

Another object of the invention is to provide a revolving stool base, the upper end of which forms a portion of the swivel for the seat.

A still further object is to provide a seat having its lower portion constructed to form a part of the seat swivel.

Another object of the invention is to furnish a swivel connection for revolving counter stools which may be readily assembled and dismantled and which permits the ready attachment or detachment of the seat roper.

A. still further object is to provide a counter stool of the revolving type, which is simpler in construction than the counter stools now in use and which may be manufactured and maintained in workable condition at less cost than the ordinary stools.

With the foregoing objects outlined and with other objects in'view which will appear as the description proceeds, the invention consists in the novel features hereinafter described in detail, illustrated in the accompanying drawing, and more particularly pointed out in the appended claims.

Referring to the drawing:

Fig. 1 is a vertical sectional view of the improved stool.

Fig. 2 is a top plan view of the upper portion of the same, with the seat proper removed.

Fig. 3 is a vertical sectional view taken on line 3-3 of Fig. 2.

In the drawing, 1 designates a pedestal or standard, which is preferably formed of metal and is of substantially conical shape. The lower end of the pedestal has a base flange 2 through which screws may be passed to secure the pedestal to the floor. The upper portion of the pedestal terminates in a cylindrical head 3 having a lower inwardly extending flange 4: and an upper outwardly extending flange 5. Said flange 5 is provided in its upper face with an annular groove, in which the lower race-ring 5 of a thrust ball bearing 5 is seated. A stationary stop 6 extends upwardly from the flange i and occupies a position within the tubular pedestal.

Resting on the head 3 of the pedestal is a two-part ring consisting of the sections 7 and 8. This ring is provided at its lower end with a hook flange 9 that loosely engages the flange 5, so that the ring may readily rotate on said flange. The two-part ring has a groove in its bottom to receive the upper race-ring 5 of the ball bearing[ The two halves of the ring are detachably connected together by suitable fastening means such as bolts 10 and when these bolts are secured in position they hold the ring in engagement with the flange 5. Obviously the removal of these bolts permits the ring to be detached so that the head 3 may be inspected and the like.

The section 7 of the ring is provided with a depending stop 11 which is adapted to engage the stop 6 for limiting the rotation of the seat on the pedestal. Arranged within the head 3 and the ring, is a coil spring 12 having one of its ends 13 anchored in the flange 4 and its other end 14 secured to the section 8 of the ring. This spring functions to turn the seat proper to a predetermined position and normally maintains the stops 11 and 6 in abutting relation.

The ring is provided with a conical cavity or aperture 15 which receives the depending stud 18 of the seat web or spider 19. This spider has radial arms 20 which support and are secured to the seat proper 21. The spider is also provided with depending apertured lugs 22, and the bolts 10 pass through these lugs and detachably secure the spider to the ring 78.

From the foregoing it is believed that the construction, operation and advantages of the present invention may be readily understood, and it is apparent that changes may be made in the details disclosed without departing from the spirit of the invention as expressed in the claims.

What is claimed and desired to be secured by Letters-Patent is:

1. In a revolving stool, a pedestal provided at its upper end with an inwardly extending flange and with an outwardly extending flange, an upright stop in the pedestal and connected to the inwardly extending flange, a segmental ring hooked over said outwardly extending flange and forming swivel connection therewith, a stop on said ring cooperating with the stop on the inwardly extending flange for limiting the rotation of the ring relatively'to the pedestal, a coil spring arranged in the pedestal and ring and having one end anchored in the inwardly extending flange and the other end anchored to said ring, bolts detachably connecting the segments of the ring together, and a seat. spider detachably connected to said ring.

2. In a revolving stool, a pedestal provided at its upper end with an internal inwardly extending flange and also with an outwardly extending flange, an upright stop in the pedestal connected to the inwardly extending flange, a segmental ring hooked over said outwardly extending flange and forming a swivel connection therewith, a stop fixed to and arranged within the ring and cooperating with the first mentioned stop for limiting the rotation of the ring relatively to the pedestal, a coiled spring arranged in the pedestal and ring and having one end anchored in the inwardly extending flange and the other end anchored to said ring, a seat spider having a stud engaging said ring, ears provided on said spider, and means detachably connecting the ears and the ring segments together.

In testimony whereof I hereunto aflix my signature.

JOSEPH S. WALTON.
