POWELL ROTARY SEAT ATTACHMENT FOR BARBER CHAIRS Filed Dec. 18, 1.944 28heets-Sheet 2 v Wang Patented Apr. 27, 1948 A UNITED STATES PATENT OFFICE OTARY SEAT ATTACHMENT FOR BARBER CHAIRS David MQPowell, La Junta, 0010. Application December is, 1944, Serial No. 568.678
This invention relates to chairs and has relation more particularly to a chair of a type used by barbers, beauticians or the like and it is primarily an object of the invention to provide an attachment for the chair whereby the operator may be seated while working.
The invention also has for-an object to provide a seat structure for use with a barber chair or the like which includes a support directly engaged with the supporting base of the chair together with a seat mounted upon the support in a manner to be readily and conveniently moved toward or from the chair and wherein the mounting for the support is such as to allow the same to be readily shifted or adjusted to any desired selected position around the chair.
The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved chair whereby certain important advantages are attained and the article rendered simpler; less expensive and otherwise more'convenient and advantageous for use, as will be hereinafter more fully set forth. 1 i
The novel features of my invention will hereinafter be definitely claimed.
. In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:
Figure 1 is a view partly in section and partly in elevation illustrating a chair structure in accordance with an embodiment of the invention, the main chair being diagrammatically illustrated;
Figure 2 is a transverse sectional view taken through the lower portion of Figure 1;
Figure 3 is a detail sectional view taken substantially on the line 3-3 of Figure 1;
Figure 4 is a detail sectional view illustrating the post holding means, certain of the parts being in plan;
Figure 5 is a fragmentary sectional view illustrating another embodiment of the invention.
As illustrated in Figures 1 to 4 B denotes a base for a chair of a type generally used by barbers, beauticians and the like and which includes the usual upstanding central column I and the bottom floor engaging surrounding flange 2. Closely surrounding the column I is a sleeve 3 of desired dimensions and which has its lower end contacting from above an annular cushion 4 of rubber or other desired material and which cushion is interposed between the sleeve 3 and the flange 2. Threading through the opposite end portions 5 Claims. (0]. 155-81) sleeve 3 by a collar ll of the sleeve 3 are the screws 5 which coact with the column I to properly center and hold the sleeve 3 in position with respect to the column. The inner ends of the screws 5 carry the yielding pads 6 which have direct contact with the surface of the column l and serve to protect such surface against marring;
The lower end portion of the sleeve 3 has integrally formed therewith an outstanding surrounding flange 1 having an upwardly facing substantially flat face a at right angles to the axial center of the sleeve 3. This face a has provided therein a continuous raceway 8 concentric to the sleeve 3. An annular member M closely surrounds the sleeve 3 and is supported by the flange 1. The under face of this member M is provided therearound with a raceWay'Q concentric to the axis of the member M and which overlies the raceway 8 when the member M is in applied position. Interposecl between the applied member M and the flange l are the ball bearings 10 which ride within the raceways 8 and 9.
The member M is held in position upon the threading upon the sleeve 3 above the applied member M. The opposed faces of the member M and the collar ll are provided with the continuous raceways l2 for the ball bearings i3 interposed between the member Mand the collar H. A
After the proper application of the member M around the sleeve 3, a dust guard or ring I is secured around the column I above the applied sleeve 3, said guard or shield being of such dimensions and design to overlie the upper portion of the sleeve 3 and extending in relatively close proximity to the applied collar II.
The member M is provided with an outwardly and radially disposed arm or block l5 having an opening theTethro-ugh in its central part. In communication with this opening i 6 is a, second opening l1 substantially at right angles thereto and which opens at the edge face of the arm or block 15. This opening it is of a. stepped type to provide the internal and outwardly facing shoulder i B.
'Insertable from above through the opening t6 and snugly fitting therein is a post l9 preferably tubular. This post 19 is of desired length and has itsu'pward end continued by a laterally inclined extension post 20. The upper or outer end portion of the extension post 20 is continued by the outwardly directed parallel spaced tracks 2| substantially in right angular relation with respect to the post l9 or more particularly the top and bottom edge faces b and 0 thereof. The tracks 2| are in relatively close proximity to 1 which extends from above each other and freely positioned therebetween is an elongated carriage block 22 of such dimensions as to extend above and below the tracks 2|. The carriage block 22 fore and aft thereof and above the tracks 21 is provided at opposite sides with the grooved wheels 23 which ride upon the top edge faces I) of the tracks 21 The carriage block 22 below the tracks 2| at opposite sides thereof and substantially midway of the fore and aft wheels 23 is provided with the grooved wheels 24 which contact with the bottom edge faces of the tracks 2|.
The carriage block 22 substantially its ends is provided with an opening a seat post 26. In swivel connection, as at 21, with the upper end portion of the post 26, is a seat 28.
Insertable within the opening I! of the arm or block l from without, is a lock pin 29 which normally engages one of the holes or notches 30 in thepost I'Sand spaced lengthwise thereof. The coaction of this pin 29 with the post l9 locks the post [9 in selected vertical adjustment within the limitations afforded by the holes or notches 30.
The lock pin 29 outwardly of the shoulder Id of the opening I! is provided with an outwardly disposed surrounding flange 3| against which presses a coil spring 32 surrounding the pin 29. This spring 32 also bears against a bushing 33 threading into the outer portion of the opening Hi This bushing 33 also provides means for regulating the tension of the spring 32 and to facilitate the desired rotation of the bushing 33 the outer end portion thereof carries an operating head 's l which at all times is positioned outwardly of the opening ii. The outer portion of the pin 29 freely passes through the bushing 23 and coupied, as by threading, to the outer end portion of this pin 29 and outwardly of the bushing 33, is a pull button 35 whereby the pin 29 may be conveniently moved outwardly into release position with respect to the post IS.
The seat post 25 is also provided therealong with the spaced holes or notches 36 with which selectively engages a locking pin 31 slidably disposedwithin the properly positioned opening 38 communicating with the opening 25. This pin 31 is mounted and operated in substantially the same manner as the pin 29 hereinbefore referred to.
It is believed to be obvious from the foregoing that a chair embodying the present invention provides means whereby a barber, beautician or kindred operator may be seated when working and it is also believed to be apparent that the operator while seated can efiectively work due to the ready rotation of the member M around the column i or more particularly to the applied sleeve 3 and also on account of the ready travel of the seat 23 along the tracks 2 toward or from the chair.
In the embodiment of'the invention as illustrated in Figure 5, the column 39 of the chair base C is provided therearound at its lower part with an outstanding integral flange 40 upon which rests from above a surrounding annular member A which is held in working position by a collar til threading upon the column 39 and coacting from above with the member A.
This annular member A has operatively engaged therewith the post 42 comprised in the operator seat structurawhich will be similar to that hereinbefore-described in connection with thefirst embodiment of the invention.
midway of I through chair or the like.
From the foregoing description it is believed to be obvious that my invention issusceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.
