Application filed August 10, 1927. Serial No. 212,071.
Another object of this invention is to pro-' duce a device wherein the operator may employ his feet for the purpose of pro elllng the stool about the operating chair t ereby leaving the hands of the operator free at all times. 7
A further object is to provide means whereby adjustments may be ready made so as to accommodate operators of various size.
A still further object is to-produce a do vice which is economical to manufacture.
Other objects and advantages W1ll be apparent during the course of the followlng description.
In the accompanying drawings forming a part of this specification and in which l ke numerals are employed to designate like parts throughout the same,
Figure 1 is a side elevat1on of an operatin chair having my device applied thereto, Figure 2 is a rear elevation of my stool, and
Figure 3 is across section view taken on the line 3-3 of Figure 1.
At the present time a barber or hair-dresser or one operating on a person sitting in a chair usually stands during the entire operation. It a stool is employed it is of the ordinary type with the result that the operator must get ofi the stool, move the stool,-
reseat himself again before working on the person.
With my device I have provided a stool having floor engaging rollers which stool is attached to the operating chair in such a manner that it may be moved entirely around so the operating chair if desired, and I further provide means rigidly securing to the operating chair whereby the operator may employ his feet in conjunction with these means to cause movement of the stool about the operating chair.
In the accompanying drawing wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates the base of an operating chair having an upstanding portion 6 which carries the usual hydraulic plunger 7"upon which a seat 8 having a customary back 9 is secured, The structure thus far described is common to many types of operating chairs and forms no. part of my invention.
I propose to attach to the upstanding portion 6 an outwardly extending flange 11 the periphery of which is provided with indentations 12 the purpose of which it will be later seen. This flange 11 has mounted therebelow a ring like member 13 upon which flanges 14 and 16 are formed. These flanges form a race-way within which a separable band 17 is adapted to rest. This band may be of any form of construction and has pivoted thereto as at 18a tubular member 19 carrying a set screw 21. This tubular member 19 is adapted to telescope one end of a horizontal brace 22 and to be held therein by the set screw 21. This brace 22 is connected to a truck 23 and if desired may pass through-the truck and bend upwardly as shown at 24 so as to engage a bearing block 26. This bearing block is braced against side movements by braces 27 and 28 which have their lower extremities secured to the truck 23.
Wheels 29 and 31 serve to support the truck from the floor. These wheels are preferably rubber covered so as to minimize any noise instant to their travel over the floor. The bearing block 26 supports an adjusting nut 32 through which a screw 33 passes. This screw is secured in a plate 34 which is in turn secured to a stool seat 36. A foot rest consisting of a cross piece is shown at 37, which foot rest is slidable upon the brace 22 and is held in adjustable position by a set screw 38.
The result of this construction is that when the device is assembled and secured to the operating chair, an operator may operate upon the person sitting in the chair and at the-same time sit upon the seat 36 which may be raised or lowered to accommodate the operators height. When operating in one position the feet may be rested upon the cross piece 37 and when it is desired to move around the person in the operating chair one or other of the feet may be brought into engagement with the depressions 12 of the flanges 11 and by pressing thereon due to the fact that the same is immovable the truck and its associated parts may be caused to move around the operating chair. This is permitted through the sliding engagement between the band 17 and the race-Way Within which it rests. It is also apparent that by loosening the set screw 21, the stool as a whole may be moved closer,
or further away from the chair as conditions demand.
10 It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size, shape and arrangement of parts 15 may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.
Having thus described my invention, I claim In combinationwith an operating, chair 20 having a base and an upstanding portion, a flange secured to said upstanding portion and having depressions formed therein, a race-way formed in close proximity to said flange, a stool spaced from said chair, a sup- 25 port extending between said stool and said chair, a band positioned in said race-way and secured to said support.
In testimony whereof I affix my signature.
