J. H. KELLOGG CHAIR Filed July 21, 1924 INVENTOR 007m H. Kelloy A TTOR/VE KY Patented Mar. 16, 1926.
UNITED STATES JOHN H. KELLOGG, OF BATTLE CREEK, MICHIGAN, ASSIGNOR TO SANITARIUM AND PATENT OFFICE.
HOSPITAL EQUIPMENT COMPANY, OF BATTLE CREEK, MICHIGAN.
CHAIR.
Application filed July 2 1,
To all whom it may concern:
Be it known that 1, JOHN H. KELLOGG, a citizen of the United States, residing at' Battle Creek, county of Calhoun, State of Michigan, have invented certain new and useful Improvements in Chairs, of which the following is a specification.
This invention relates to improvements in chairs. 7
The main object of this invention is to provide an improved chair adapted to support the body of the occupant in a natural and helpful position and also one. which tends to cause the occupant to assume that position When occupying the chair.
A further object is to provide a chair having these advantages which is attractive in appearance.
Objects relating to details and economies of construction and operation will definitely appear from the detailed description to follow.
I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.
A structure which is a preferred embodi ment of myinvention is clearlyillustrated in the accompanying drawing, forming a part of this application, in which: Fig. I is a perspective view of a chair embodying the features of my invention.
Fig. II'is a fragmentary vertical central section on a line corresponding to line 2-2 of Fig. III. Fig. III is a horizontal section on a line corresponding to line 3-3 of Figs. I and II.
In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in thedirection of the little arrows at the ends of the section lines.
Referring to the drawing, the seat 1 of the structure illustrated is an upholstered seat which is suitably mounted upon the frame 2, the front legs 3 being secured in the usual or any desired manner, the joints of the frame and legs not being illustrated. The rear legs 4: are'extended upwardly into back side posts 5. These posts are connected at their upper ends by the top cross bar 6,' this bar being straight. The bottom cross-bar 7 extends between the posts, the bar 7 having a rearwardly bowed central 1924. Serial No. 727,282.
portion 8, this bowing or curving being quite substantial in degree. j
I provide vertical slats 9, 10 and 11 the slat 9 being the center slat, the slats 1] the outer slats, and the slats 10 intermediate slats. These slats are bowed forwardly with an irregular curvature so that the crown of the bows on the most forward portion thereof is below the longitudinal center of the slats. The degree of curvature or bowing of the slats increases from the center slat 9 to the outer slats, that is, the degree of the bowing of the slats 10 exceeds that of the center slats and the bowing of the outer slats 11 exceeds that of the slats 10. This results in aback having a horizontally concaved lower portion which merges upwardly into a horizontally concaved vertically convex intermediate portion which in turnmerges upwardly into a substantially fiat rearwardly inclined upper portion.
In a chair thus formed, the body of the occupant is supported from the hips to the shoulders, the rearwardly curved or convex portion at the back accommodating the hi s of the erson when seated well back in t e chair, he intermediate portion supporting the small of the back and the upper flat portions supporting the shoulders. The back has a general rearwardly inclination so that the shoulders may be thrown well back, bringing the so that the body is perfectly balanced and the occupant seats easily and comfortably in the chair. I
My improved chair supports the body in j a helpful position and also has the advantage of tending to cause the occupant to assume that; position.
I have illustrated my improvements as I have embodied the same in a dining chair. I have not attempted to illustrate or describe the adaptation thereof to rocking or other chairs as I believe the disclosure made willenable those skilled in the art to embody or adapt the same as may be desired. Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is: I 1. In a chair, the combination with a rearWardly' inclined seat, of a back comprising rearwardly inclined posts, a straight top cross bar connecting the upper ends of said ead to a proper poise posts, a bottom cross bar disposed in spaced relation to said seat and having a rearwardly bowed central portion of substantial curvature, and a plurality of vertically disposed slats extending between said cross bars, said slats being forwardly bowed with an irregular curvature, the bowing of the slats increasing from the central slat toward each side of the back, whereby a back is provided having a horizontally conc'aved lower portion merging upwardly into a horizontally concaved and vertically convex intermediate portion which merges upwardly into a substantially flat rearwardly ,inclined upper portion.
2. In a chair, the combination with a seat, of aback comp-rising posts, a top cross bar connecting the upper ends of said posts,
a bottom cross bar disposed in spaced relation to said seat and having a rearwardly bowed central portion of substantial curvature, and a plurality of vertically disposed slats extending between said cross bars, said slats being forwardly bowed with an irregu- ,bar, a rearwardly lar curvature, the bowing of the slats increasing from the central slat toward each side of the back, whereby aback is provided having a horizontally concaved lower portion merging upwardly into a horizontally concaved and vertically convex intermediate portion which merges upwardly into a substantially flat upper portion.
3. In a chair, the combination with a seat, of atback comprising posts, a top cross bowed bottom cross bar, and a plurality of vertically disposed forwardly bowed slats extending between said cross bars, the bowing of the slats increasing from the central slat toward each side of the back, whereby a back is provided having a horizontally concaved lower portion merging upwardly into a horizontally conoaved and vertically convex intermediate portion which in turn merges upwardly into a substantially flat upper portion.
In witness whereof'I have hereunto set my hand.
JOHN H. KELLOGG.
