IMPROVEMENT INBlARBERS CHAIRS.
- Specification forming part of Letters Patent No. 192,898, dated July 10, 1877; application filed I February 24, 1877 To all whom it may concern:
Be it known that I, JOSEPH GLOUGH, of the city and county of Providence, in the State of Rhode Island, have invented certain new and useful Improvements in Barbers Chairs; and I do hereby declare that the following specification, taken in connection with the drawings furnished and forming a part of the same, is a clear, true, and complete description thereof.
My said improvements in chairs contribute largely to their practical value, in that they are capable of a more comfortable adjustment for occupants thereof during the operation of shaving than any other chair of which I am cognizant, and also in that the movable parts of the chair are so connected with the main portions thereof as to enable me to secure strength and durability while employing a minimum of bulk in material.
'The main feature of my invention consists in the combination, with a pivoted chair-back, of a sliding head-rest, which is attached thereto, and has a movement in a lineobliquely to the vertical line of the back. In pivoted-back chairs, as well as in those in which the back has no movement, the sliding head-rests, as heretofore constructed, have a movement parallel with the verticalline of the back. The peculiar value of having the head-rest mounted in accordance with this feature of my invention will hereinafter be fully set forth.
Another feature of my invention consists in the combination, with a pivoted chair-back, of a head-rest guide-bar which is rigidly connected to the top and bottom rails of the chairback, and serves as a strengthening-brace. This bracing feature is of practical importance in view of the fact that the back is mounted on pivots attached to the sides thereof.
Another feature of my invention consists in the combination, with the back of achair, of flan ged headed pivots attached to the sides ofthe back, and open sockets or-mortises in the sides of the chair,which receive the flangedhead pivots, and by a lateral engagement therewith enable the back and its pivots to serve as a lateral tie for bracing the two sides of the chair. I
To more particularly describe my invention,
same in end view, showing the entrance to the mortise or socket.
The back of the chair, as at A, is mounted on two pivots, one on each side thereof, as at a. These pivots are located at a point nearly midway between the top and bottom of the back, so that the backward movement of the top thereof will substantially correspond in its extent with the forward movement of the bottom, and thus secure the desired degree of inclination with a minimum of movement. On
the inner surface of each arm of the chair are two lugs, as at b, which limit the swinging movement of the back. A latch-bolt, as at b, is employed for engaging with the back, and holding it in position for hair-cutting, as in Fig. 1. Each arm of the chair is provided with an open mortise or socket, as at a, for the reception of the pivots a. These open mortises are chambered, so that the flanged heads (1 of the pivots a may freely enter from the rear. The inner surfaces of the heads 01 engage with the coincident inner surfaces of the mortises.
By means of the flanged-head pivots and the open mortises, as described, the back can i be readily removed, as occasion may require, and the back, when mounted in the mortises, serves as a tie-brace for strengthening the two arms of the chair. The head-rest at B has a stem, as at e, which, in itself, is substantially as heretofore. Its guiding-sockets, however, as at f, are mounted on a head-rest bar, g, which is connected to the top and bottom rails of the back, and the guiding-sockets are set on the bar g. As heretofore constructed, the stem of the head-rest has been fitted to guides attached only to the upper portion of the back, or to a bar projecting downward therefrom for a short distance only.
The head-rest stentis provided'with notches an'd a spring-catch, as heretofore, for maintaiii'in'g' it at any desired elevation.
It will be seen thatthe chair is well braced and strengthened laterally by the back, its
tages of having the head-rest movable in a) line which is oblique to the line of the back, instead of in a line parallel with the back, I
have introduced into Fig% 2 is dotted lines,- a"
head-rest, as heretofore constructed:-
It is well known that head-res'tsare made i I a pivotedfback, of" a sliding head-rest, which is movable in a' I-ine obliquely to thew-meat line o'fithe bac'k,- subst'antially" as described adjustable in order that the chair may be" adapted to the I physical peculiarities of differ-'- ent persons' as; for instance-, a short=bodied person with a short neck-would require" the he'ad rest'in the position shown iii Fig: 1; closely adjacentto the top of the baek-of'the' ch a'ir; andthe'refor'e' for such a person-the Wduldne'ed tobe inelin'edonly. For eersons with longer bodies and necks" thejh'ead-rest must be adjusted so as to not-mereiysnpport the -head, but alsdso-a's to comfortably i'n'aintaiil itin at position most favorable for the shaving operation;
For the comfort of v the occupant the head" rest should be in contact with the rear of the head adjacent to its junction with the spine; and when thus in" contact thehead is'well supported, and the chin properly elevated without straining the neck. Withmy headrest the head of a person may be thus supported, even if it be requisite to elevate the rest to its maximum height; but, as will be seen by the dotted lines in Fig 2, the parallel headrest; when fully ektended;only afi'ords a support after the head has been thrown backward ,to a much greater extent than with my rest, and that if the rest be in contact with the central rear portion of the head, the chin will not be properly elevated, and on the other hand; if'tlfe rest be iii Gdfit'a'iiitWitH-tlid-lower rear portion of the head,' the neck will be un- H comfortably strained.
Having thus described my invention, I claim as new and desire to secure-- by weste ns-hers Patent it in abarberscnair; the combinefien, with 2 TlideOhiliihattibii, with is pivoted bacli; of a Headrest-bar, g",- which is rigidly connected with tnetcp' and" bottomrails of the back; substantially as described.
