l BARBER/S OR DENTISTS STOOL.

Application filed April 21, 1925. Serial No. 24,813.

To all whom t may concern.'

Be it known that I, ULYssis R. MOORE,

a citizen of the United States, residingat Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Improvement in Barbers orDentists Stools, of which the following is a specification. o

This invention relates to stools for bai-bers or dentists.

The object is to provide a means for permitting a dentist or barber to sit, when desired, while at his work, in order to relieve himself of the extremely tiring effects of long continued standing upon his feet, the said means consisting of a strong, durable and simply constructed stool having a slidable connection with the dental or barbers chair, so that the same is coni-med to an area about the chair wherein said stool may always be easily reached, and yet may be moved or shifted into an out-of-the-way position to enable the operator to freely move while on his fee-t.

Another object is to provide a stool of this type having a stool seat which may be easily and quickly elevated tol the desired height to suit the operator, and which may. be moved in a horizontal plane to any desired position without moving or sliding the stool proper, so that the operator may partially sit upon the same, with one foot upon the floor, if desired, thus affording a means of relief between his necessary movements about the shop or oliice, it being necessary to only move the seat independently of the stool, into active or out-ofethe-way position by a simple movement of the hand and without effort.

A full and complete understanding of the invention may be obtained from a consideration of the following detailed description, taken in connection with the accompanying drawing forming a part of this specification, it being understood that while the drawing shows a practical form of the invention, the latter is not to be confined to strict con formity with the showing thereof, but may be changed or modiied,so long as such changes or modifications mark no material departure from the salient features of the invention, as specically pointed out in the appended claims.

In theV drawing, in which similar reference characters designate corresponding` parts throughout the several igures:-

Figure 1 is a siderelevation of the improved stool secured in proper position with relation to a barbers or dentists chair.

Figure 2 is a plan view of the same.

Figure 3 is an enlarged vertical sectional view of the upper portion of the stool and showing the means for elevating the seat and swinging the same in a horizontal dil rection, the saine. being taken on the line 3 3 of Figure 2.

Figure 4 is a detail sectional view on a larger scale of the means for guiding the stool about the chair, said view being taken on the line 4-4 of Figure 2.

Figure 5 is a similar view showing they manner of pivotally mounting the arm for supporting the instrument tray carried by the improved stool. l

Referring to the drawing there is shown a stool comprising a disc-like head 1, formed preferably of some hard, durable wood, ory

the same may be formed of a light casting, or of stamped sheet metal of suitable strength. The head 1 is provided on its lower surface with outwardly directed, radially disposed sockets 2, formed of suitable castings held in position by screws or other fasteners. The sockets receive the upper ends of inclined legs 3, formed preferably of strong wood, but the legs may be connected to the head in any other manner, such as by forming the sockets directly in said head, as will be understood.

In the drawing there is shown three of such legs, though a greater number may be employed, and vtwo of the legs are shown somewhat longer than the third and are equipped, at their lower ends, with ordinary casters 4 to rest and to roll upon the floor of the shop or oflice. The third leg as has been stated, is shorter than the others, and is provided with a metallic socket 5 at its lower end, which is suitably secured to the same, and which is provided with an outstanding, horizontally disposed arm 6, eX- tendiiig radially tothe center of the stool head 1. The outer end of the arm 6 is provided with a reduced portion 7 to constitute a spindle for the reception of a roller 8, which is held on said spindle by a. screw 9, as clearly shown in Figure 4 of the drawing.

Adapted for coaction with the roller 8 is (iti a circular track l0, torined having a plurality of legs 11 secured to the underside thereof, said legs being designed to be fastened to the floor and'to rigidly secure the track in elevated position above the saine, in surrounding relation to the base and pedestal 12 of a barbers or dentists chair 13.

The track is provided in its outer periphery with a continuous entrance slot 14 through which the aforesaid arni 6 is adapted to pass, theroller 8 being of dian'ietcr to :Freely rotate within the tubular, circular t ack 10, thus preventing the urin (i, together with the entire stool. troni being inoved radially troni the tr. and holding said stool in such relation to the atoresaid chair ln order to tacilitate assembling the parts at this point, the track is provided in its inner wall with aperture lo of a size to perinit the screw 9 to pass therethrough which.5 atter the roller 8 has been placed edgewise through the slot` lll and turned to an upright position, and after the spindle 7 ot the arin t has been passed through the bearing or bore or the roller, inay be readily threaded into the counterbore of said spindle, in an obvious inanner.

At the center ot the stool head 1 there is attached a threaded sleeve 16 extending through the saule, and having an attaching llange 1"!" to be screwed to the upper lace oit said head, said sleeve being adapted to receive a. threaded shatt 18, the upper end ot which is reduced, as at 19, and which has a suitable hand wheel 2O secured thereto at the lower end ot the reduced end 19.

An arm 2l preferably of flanged torin to provide su 'i lent strength and lightness, is provided with an eye 22 at one end which is adapted to receive the reduced end 19 et the adjusting screw or shaft, which is rotatably held thereon by a nut 23, the opposite, free end ot said arin being provided with a similar ye or bearing lier the reception of aI pivotal bolt 24.

in upper arin 25 having a bearing 26 at one end for the reception ot the upper portion of the pivotal bolt 2d, is mounted above the lower arin and is adapted to freely swing with or independently of the saine, the two arins being' held together upon the bolt by a nut 27. The opposite, l'ree end ot the upper arin 25 is provided with an aperture 28 into which lits the reduced end 2.() o't a stud 3i having an attachingflange 31 at its upper end, to which is held, as by screws, a revolving seat 32, preferably of circular forni and dished, as shown, the said seat being preferably lfornied ot wood and soinewhat smaller in diameter than the head l ot the stool.

At an intermediate point between the Hoor and the stool head 1, the legs 8 carry a circular toot rest 33 extending entirely around ot tubing, and

the legs and secured thereto as by screws 34, the said rest being termed of wood or of light tubing, as desired.

@ne ot the legs 3 having the casters l attached thereto, is provided, at a point above the foot rest 33, with a vertical socket 35, into which there is reinovably fitted the lower end Sii ot an instrument tray supporting rod 3'?, the saine being bent into the torni or a compound curve, and provided with a circular flange 3S to rest ugon the upper end of the socket The support inay be swung into various positions about the axis of the socket, and the saine is provided at its upper end with a rotatableltable or instrument tray or support 39, having a socket secured to the under tace thereof and the center to receive the upper end ot the rod 37 and perinit independent rotary inoyeinent of the said table.

lllhen the operator is at work he inay inove the stool around the chair 13 to any point to be out ot his way it he is standing upon his li'eet, the connection between the roller and track preventing' the stool from being inoved out oit' reach. Vllhen he desires to sit upon the seat 32, he inay or -ray not have to nieve the stool bodily around the track to the desired position to receive his full weight. Atother times Whei'i he desii-es to just partially sit upon the seat With one toot upon the floor, he need only move the seat to the desired location, such Inoveinent being freely aerinitted by the action or" the arins 21 and 25 together with their pivotal connections. The toot rest is always in position to receive the foot or feet when the operator is squarely seated on the seat, and the tool or instrument tray support, likewise, is always ready at hand to receive or deliver articles placed thereon.
