COMPLETE SPECIFICATION.
Improvements in Swinging Chairs.
I, JULIUS M. ELLER, of Cleburne, in the County of Johnson and State of
Texas, 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 an improvement in swinging chairs more.
especially adapted for children; and it has for its object to provide such a chair
with means which will render the chair automatic in operation or require but little
exertion from the child occupying it, there being little or no danger of the child
falling out while the chair is swinging.
The invention will be fully understood from the following description and claims.
when taken in connection with the annexed drawing, in which my invention is.
illustrated in a perspective view.
Referring by letter to said drawing, A indicates a chair having the usual seat-.
back and arm-rests and may be a chair of any ordinary or approved construction..
The chair I have illustrated is provided with a foot-rest a, suspended from
hangers b, secured to the seat of a chair.
B indicates the suspending-ropes. These ropes are of the character usually
employed on swings, and are designed to be secured at their upper ends by screw-
eyes c, or the like to a ceiling or other suitable support.
D indicates a cross-bar, which is secured transversely to the forward under side
of the chair-seat and projects from the opposite sides of the chair, as shown, where
it is preferably provided with knobs d, or other suitable stops for the attaching
ropes. It will be observed that this bar is fixed out of the center of the chair-seat
and in advance thereof, so that a child occupying the chair will find the rear portion
yieldingly sustained, as will be presently described.
E indicates a rope, which is secured at its lower end to the rear side of the seat,
as shown at e, and after being secured to the back of the chair, as shown at f, has
its opposite end attached to a spiral or coiled spring F, which spring may be in turn
secured to the ceiling or other suitable support in a manner similar to the chair-
suspending ropes.
In order to render my improvements capable of being employed on any ordinary
chair-seat, I may provide the cross-bar D with such fastening devices as to make
it readily detachable, in which cases the rope carrying the propulsioned spring
might be provided with a screw-eye for attachment to the back of the seat, when
the ropes, cross-bar, and spring may be placed upon the market as adapted for
attachment to any chair.
From the construction described it will be readily understood that when a child
sits in the chair the spring given to his weight will have a tendency to impart a
swinging motion to the chair, and by the child inclining his body backward
and forward the spring will propel the chair by its alternate expansion and
contraction.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1. The combination, with a chair, of the cross-bar secured to the forward under
side of the seat, the suspending-ropes secured at one end to the opposite ends of
said cross-bars, the rope secured to the rear side of the seat, and the propulsioned
spring secured to the opposite end of said rope, substantially as specified.
2. The combination, with a chair-seat, of suspending-ropes attached at their
lower ends to the opposite forward sides of the seat, a rope secured to the rear side
of the seat, and a spiral or coiled spring secured to the opposite end of said rope,
substantially as specified.
