l 1 This invention relates to new and useful improvementsland structural refinementsin stools for barbers, dentists, beauticians, or other per: sons engaged in the performance of services upon a customer or patient seated in a chair, the principal object of the invention being to permit the operator or attendant to assume a sittingposition while working, so that the comfort and .efliciency of the attendant is not impaired by fatigue incident to working in a standing position,

One of the features of the invention resides in the provision of a unique base plate on which the attendants stool is mounted, this base plate being adapted for positioning under the usual base of the customers chair, whereby the attendants stool is firmly and rigidly supported.

Another feature of the invention involves the provision of an adjustable leg member on the base plate for supporting the seat of the stool, by

virtue of which leg member the position of the a seat relative to the customers chair may be adjusted in a horizontal as Well as in a vertical plane.

Some of the advantages of the invention lie in its simplicity of construction, in its convenient operation, in its pleasing appearance, and in its adaptability to economical manufacture.

With the above more important objects and features in view and such other objects and features as may become apparent as this specification proceeds, the invention consists essentially of the arrangement and construction of parts as illustrated in the accompanying drawings, in which:

Figure l is a perspective view of the invention;

Figure 2 is a fragmentary cross sectional detail, taken substantially in the plane of the line 2-2 in Figure 1;

Figure 3 is a top plan view of the subject shown in Figure 1;

Figure 4 is a cross sectional view, taken substantially in the plane of the line 4-4 in Figure 3; and

Figure 5 is across sectional detail, taken substantially in the plane of the line 55 in Figure 1.

Like characters of reference are employed to designate like parts in the specification and throughout the several views.

Referring now to the accompanying drawings in detail, the invention consists of an attendants stool designated generally by the reference character I0, such as may be conveniently and effectively employed in association with a customer's 5 Claims. (Cl. 155-81) chair, the usual circular base of the latter being illustrated by the phantom lines l2 in Figure l.

The stool assembly [0 embodies in its construction a base plate [4' consisting of a crescentshaped body portion 16 and an arcuate rim [8 which is secured at the ends thereof to the ends of the body portion [6 and coacts therewith todefine a substantially circular opening 20, as illustrated in Figure 1.

The base plate [4 is intended to be positioned under the base l2 of the customers chair in such manner that the base [2 .covers the openingZD while a portion of the'base plate body is projects outwardly to one side of the base 12, this projecting portion having secured thereto an upright,

substantially tubular socket 22. This socket may be welded or otherwise secured to the base plate portion [6 and if desired, suitable gusset plates 24 may-be employed for additional reinforcement, as will be clearly apparent.

-A substantially L-shaped leg member 26 has one arm thereof removably and rotatably positioned'inthe socket 22, and the remaining arm of the member 26 is provided with a second, upright tubular socket 28. r

A second leg member 30 includes a lower portion 32 which is removably and rotatably positioned in the socket 28, while the upper end por tion of the leg member 30,'indicated at 34, is laterally offset with respect to the lower portion 32 and is formed with a helical groove 38.

A seat 38 is mounted, as will be hereinafter more fully described, on the upper end portion 3 3 of the leg member 30, and it will be apparent from the foregoing that the arrangement of the leg members 26, 30 is such that the position of the seat 38 relative to the customers chair may be adjusted as desired in a horizontal plane, such as for example is indicated by the phantom lines 40, 42 in Figure 3.

In addition to the adjustability of the seat in a horizontal plane, means are also provided for adjusting the seat vertically, that is, for varying the distance of the seat from the floor, this means residing in the structure used for attaching the seat to the leg member 36. This is accomplished by providing a tubular adapter 44 on the underside of the seat 33, the adapter 44 being secured to the seat by means of suitable bolts 46 extending through a flange 48 with which the adapter is equipped, the adapter 44 being rotatably positioned on the upper end portion 34 of the leg member 30, as is clearly shown in Figures 4 and 5.

scope 'of the invention as claimed.

a sleeve 54 which is positioned on the adapter h 44 and is equipped with a set screw 56, the shank thereof to the ends of said body portion and coacting therewith to define a substantially circular opening, said socket being mounted on said body portion and said base covering said opening.

2. In combination with a customer's chair including a base, an attendants stool comprising a flat base plate positioned under said base and projecting outwardly to one side thereof, an upright tubular-socket mountedon the projecting portion of said base plate, an L-s'hapedleg mem- .ber having one arm thereof removably and ro- 'tatably positioned in said socket, a second upof the latter extending into the' aperture 50 in engaging the ball 52; so that the ,set screw. 56

actually performs a double function, namely,

that of retaining the ball 52 in engazgen' entwithj 1 the groove 36, and secondly, for retainingthe sleeve 54 in position on the adapter 44.
