page_text: I, GEORGE FRANKLIN HALL, residing at Long Branch, in the County of Monmouth,
and State of New Jersey one of the United States of America, gentleman, do hereby
declare the nature of this invention and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement :-
This invention has relation to rocking chairs, and more particularly to that class
thereof which are suspended upon hangers; and the invention consists in certain
features of construction hereinafter described, and particularly pointed out in the
claims.
Referring to the drawings:-
Figure, 1, is a vertical section of the frame work of a chair and base embodying my
invention.
Figure, 2, is a front elevation and,
Figure, 3, is a detail illustrating a modification.
Like letters of reference indicate like parts in all the figures of the drawing.
A, represents a base, which may be of any desired design, and which is perforated
as at, A, in the form of bearings for hangers, B. The only requisite in the design of
the base is that it shall have open spaces for the passage and swinging movement of
the hangers employed to support the chair thercon. C, represents the chair, the frame
work of which in this instance is extended below the seat rail, C³, thereof in the form
of brackets or legs, C2, which are perforated as at, C³, in the form of bearings for the
hangers, B. When however, it is desired to embody my invention in chairs which are
not provided with legs or brackets, C2, I provide standards, C2, (see fig. 3.) of metal,
perforated in the form of bearings as at, C, and having at their upper ends attaching
plates, C, whereby the same may be secured to the seat portion of the frame work of
such chairs in order that they may be mounted upon a suitable base provided with my
hangers.
In this instance the base, A, is provided with three tie-bars, A3, which serve the
purpose of maintaining the sides parallel with each other. Each of the hangers, B,
consist of a horizontal shaft, B', reduced at one end to form a bearing, B2, and a

page_text: shoulder, B, and being at the opposite end, either plain or screwthreaded as at, B'.
Near the shouldered end of the shaft there is provided a downwardly projecting
suspension arm, B5, which is bent outwardly, and provided with a journal B, and
shoulder, B³, similar to the bearing and journal, 132, and shoulder, B3, but the
suspension arm is extended laterally after being bent so as to bring the two journals
into different vertical planes, in order that when the journal of the shaft is mounted in
the base, A, the journal portion of the suspension arm will pass through the base, A,
and extend into the bearing C³, formed in the brackets of the chair frame or their
described equivalent.
A coupling, D, is employed with each pair of suspension shafts in such a manner
that said shafts are inserted into each end of the coupling, and secured therein by set
screws, D. When, however, screwthreads, B', are formed on the ends of the shafts,
the coupling is interiorally threaded to work in the ends of the shaft, the coupling
being the wellknown running thread coupling. This being the construction, it will be
seen that each of the lungers or suspension shafts can be separately inserted into the
bearings provided for them in the base, and the coupling subsequently moved from one
shaft onto the other, and secured into position so that the chair may be suspended upon
the base without taking the frame work of either apart.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed I declare that what I claim is -
1. In a chair of the class described, suspension hangers having a connecting and
supporting shaft, made in separable parts, and provided with a coupling device,
substantially as specified.
2. In a chair of the class described, the combination with the chair frame provided
with bearings for a hanger, a base provided with similar bearings, separable hanger
connecting and supporting shafts and couplers for the same, substantially as specified.
3. The hanger, B, provided with the journals, 132, shoulder, B³, suspension arm, B³,
bent as described and provided with the journal, B6, and shoulder, B³, substantially as
shown and described.
4. The combination with a base having bearings for a hanger, and openings for the
suspension arm thereof, of a chair frame having bearings for said suspension arms
and of a coupling mounted on the separated connecting and supporting shaft of the
said suspension arms, substantially as specified.
