HENRY S. HALE, OF PHILADELPIIIA, PENNSYLVANIA.
SPECIFICATION forming part of Letters Patent No. 277,272, dated May 8, 1883.
Application filed November 24, 1882. (No model.)
To all whom it may concern Be it known thatl, HENRY S. HALE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvementsin Chairs, of which the following is a specification, reference being bad therein to the accompanying drawings.
Figure 1 is a perspective view of a chair having my invention applied thereto. Fig. 2 is a perspective View, showing a modification and Fig. 3 is a perspective view of my improved back-frame.
The object of this invention is to facilitate the removal from a chair of that portion of the back which is ordinarily arranged between the two upright posts, whenever it is found desirable, to permit the backs to be conveniently repaired or beaten or otherwise cleaned.
Referring to the drawings, A A are the front legs. B B the rear legs, and (J the seat, of the chair, which latter maybe upholstered in any approved or desired manner.
D1) are the posts, which in practice I usually prefer to make each in one and the same piece with the corresponding rear leg.
E E is a girt having its ends framed into the posts D D, its upper part, E, constituting a rib or web, for a purpose which will soon be explained.
F is a rod, tie-bar, or girt connecting the upper ends of the posts, and may be either a round rod, as shown, or it may consist of a square or fiat bar of either wood or metal; but in preference I prefer the construction shown.
As I prefer in practice to use my invention in the form shown in Figs. 1 and 3, I will first describe that figure.
K L M represent, respectively, the top, bottom, and one of the side rails of a back-frame, there being, of course. another side rail, M, at the opposite ends of the top and bottom rails, thus constituting a rectangular frame adapted to receive. and support a suitable upholsterin g,
- which may be of any usual or approved construction. The top rail, K, is provided upon its rear side with a longitudinal upwardly-inclined groove or recess, k, adapted to receive the bar or girt F. The bottom rail is also re- ]cessed, as at 1, to receive the upwardly-pro jecting rib E.
In Fig. 2, which shows a modification of my invention, G H I I are respectively the top,
bottom, and side rails of a rectangular frame,
and J the upholstering, the whole constituting a removable back of a chair having many features in common with the back which I have just. described when referring to Fig. 3; and it will be seen that when either of these backs is applied to the other parts of the chair there exist in the back of said chair two substantially rectangular frames, the removable one being supported by means of recessed bars or rails upon the cross-girts which constitute a portion-of the outer permanentframe of the chair.
By an examination of the drawings it will be readily understood that when either of the seat-backs is supported upon the girt E E and the girt or tie-bar F, over which the recesses are adapted to fit, the backs will be held firmly in position, and will not beliable to accidental displacement, but can be readily removed from between the posts; and it will also be seen that when the construction of frame shown in Figs. 1 and 3 is employed the rib E and tiebar F are entirely concealed, and that, as there are no joints or open crevices in sight, the finished appearance of the chair is not marred by any of the devices by means of which the removal and replacement of the back is made possible. A
It will of course be understood that so far as relates to supporting the lower end of the back the part E of the girt might be dispensed with, the ends of the rib E being attached to the posts by tcnons and mortises or otherwise.
Although in the drawings the ends of the girt E E and of the tie-rod F project through the posts D D, and are therefore visible, I prefer to so construct the parts that these ends do not extend through tothe outer faces of the posts, or else cover them with some ornamental devices.
Although I have shown my invention as applied to an ordinary four-legged and straightbacked chair of very plain design, I do not wish to be limited thereby, it being apparent ICO that it is equally well adapted for use upon other styles of chairs and the backs of various seats, such as are used in railroad-cars, streetcars, sofas, and similar articles of furniture.
One advantage of my invention is that it utilizes the transverse girts or tie-bars substantially such as are ordinarily employed for connecting the upper and lower ends of the back-posts.
Another advantage is that it utilizes the upper and lower rails with which very many chairbacks are provided by simply grooving them, as indicated in Fig.3. Thus no increased numher of parts is required beyond such as are frequently found in seat-backs.
It is evident that it would be difficult to form the groove 1 except with its walls paral-.
lel to the sides of the rail L, and yet have-it fit closely the rib E and be conveniently applied thereto, and it is also apparent that it is desirable to form the girt E E in such mancar that it shall serve as a part of the framework of the chair, whereas the groove k may be formed with its walls at an inclination to the sides of the rail K, and yet be conveniently applied to the girt I hence a construction which could be advantageously used in the top rail mightbe practicable for the lower rail.
I do not claim herein any invention which is patented to me in my patent dated April 17, 1883, application for which was filed February 24, 1883, serial No. 86,112, of which this is a division.
What I claim is- 1. In a chair, the combination, with the posts D D and the tie-bar or girt F, extending from post to post, of the removable back having a rectangular frame adapted to receive and support the upholstering, and being upwardly recessed to engage with the girt I substantially as set forth.
2. In a chair, the combination, with the posts D D, the tie-bar or girt F, and the girt E, pro vided with the upwardly-projecting rib E, of the removable back having a'rectangular frame adapted to receive and support the upholstering, and being upwardly recessed to engage with the upper and lower girts, substantially as set forth.
In testimony whereof I aflix my signature in presence of two witnesses.
