Improvements in a Child's Adjustable Chair.
We, ROBERT JOSEPH MOORHEAD, and MARVIN ANTHONY CALDWELL, of North East,
in the county of Erie, and State of Pennsylvania, United States of America, Gentlemen,
do hereby declare the nature of our invention for "IMPROVEMENTS IN A CHILD'S
ADJUSTABLE CHAIR" and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:
Our invention consists in the improvements in a childs adjustable chair, hereinafter
set forth and explained, and illustrated in the accompanying drawings, in which:
Figure 1 is a perspective view of the chair adjusted to operate as a rocking
chair.
Figure 2 is a like view of the chair adjusted to operate as a high chair.
Like letters refer to like parts in all the figures.
In the construction of our improved chair the body of the chair A is of the usua!
and ordinary construction; this chair body A is mounted on a double set of rockers BB
and CC; the set of rockers B B fitting between the rockers C C and being centrally
pivoted thereto by a round b so that when closed together as shown in Figure 1 the
two sets of rockers are parallel. To the cars c c on the front ends of the rockers CC
the lower ends of the front legs of the chair body A are pivoted and in the rear the
ends of the rockers B B is mounted a rotary round E through which links or rods of
wire operate. One of these links F is pivoted to the inside of each of the rear legs G G
of the chair body and passes through small holes in the rotary round E so that they
will slide freely therein and are provided in their lower ends with small heads to
prevent them from being withdrawn therefrom. The rear ends of the rockers B
are cut off somewhat shorter than the rockers CC so as to admit of the round e being
secured between the rear ends of the rockers CC. The rear ends hh of the rockers,B B
are also hollowed out so as to fit the under side of the chair rounds d d which rost
thereon when the chair is adjusted to operate as a high chair as illustrated in Figure 2.
The front ends of the rockers B are also provided with a transverse round y secured
therein. On the front of the chair legs D D a step or foot rest H is secured in the
usual manner.
In operation the chair when adjusted as illustrated in Figure 1,
operates as a childs rocking chair. In order to adjust it as a high chair as illustrated
in Figure 2, the round a is grasped by the hand of the operator while the foot is
placed upon the round e at the rear end of the rockers CC, the chair body A is
then lifted up, the links F raising the rear ends of the rockers B B until the rockers BB
and CC are opened up so that the rounds D of the chair body rest upon tho rear
ends of the rockers B B when it operates as a high chair; to adjust it back again this
operation is reversed.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
1. In a convertable chair, the combination, with the outer rockers pivoted to the
front legs of the chair, of the inner rockers pivoted centrally to the outer rockers and
forming a double rocking surfaco at the base of the chair, a round journaled in the
rear ends of the said inner rockors, and sliding links pivoted to the rear legs of the
chair and engaging with the said round, substantially as and for the purpose set
forth.
2. In a convertable chair, the combination, with the outer rockers provided with
ears c c pivoted to the front legs of the chair, of the inner rockers pivoted centrally
to the outer rockers and provided with grooves in their rear ends for engaging
with the rounds d of the chair, the revoluble round E journaled in the inner rockers,

forth in holes formed through the said round E, substantially as and for the purpose
set forth.
