Berlin Germany " IMPROVEMENTS IN CHILDREN'S CHAIRS." (A communication
from Louis Schmetzer of Rothenburg on the Tauber, German Empire)
This chair is so constructed that it may also be used as a child's go-cart with
castors. For this purpose the seat is fastened to the under framing so as to be
removable therefrom, and the legs which are made to swivel on the under framing
in the usual manner are provided with castors which only come into action when
the chair is to be made into a go cart. There is on the under framing an open or
three sided frame with a ring cushion attached thereto and serving to hold the
child when running. By uniting the seat cushion with the lid for the closet the
hole through the latter is closed and the seat cushion kept securely in place. The
chair is also provided with a foot step which can be shifted in position according
to the length of the child's legs. The closet pan is attached to the seat so that it
can be conveniently removed therefrom and for this purpose a half round or bow
shaped metal bar with spring and catch hook are provided at one side of the closet
opening, the hook corresponding with an opening in a bracket on the pan and into
which it is pressed by the spring.
The legs which may be provided with wheels or not are as usual by pivots
connected to the cast iron frames and are kept in their normal extended or down
position by means of a cast iron holder for each two legs, each holder being jointed

page_text: at one end to the upper prolongation of one leg and resting against the upper
prolongation of the other leg. On raising these holders the legs spread out and
the height of the chair is thereby reduced In this position the castors which are
connected to the side of the legs will touch the ground. The holders one on each
side of the chair are at their upper ends united at top by a bent up part on each
side of the aforesaid three sided frame for the ring cushion; The seat is removably
fixed to this frame: for this purpose the seat board is pushed back into and under
the bent up parts and is kept in position in front by a hook passing through an
opening in the frame and behind a spring catch. The ring cushion is fixed to this
frame as stated and the child is tied into this cushion after the removal of the
seat and the raising of the chair legs; the chair will then be used as a go-cart.
The scat board has the closet pan hole through; and the pan lid is directly
connected to the seat cushion. In this way the pan lid also serves as a means for
securing the seat cushion. The pan is made of tinned iron (instead of stoneware
as heretofore) and has the top edge bent over. The stoneware pans easily break
at the edge and they can then not be fixed to the seat by the lugs and bars
thereon; the wooden lugs and bars are also done away with, as they swell when
wet and thus prevent the pan from being pushed in. Instead of the wood lugs
and bars there is provided on one side a half round or curved metal bar which by
means of pegs is connected to the underside of the seat board a slight distance
therefrom; this distance corresponds with the height of the bent over top edge
of the pan; between the bar and the seat board there is a spring which rests
against the upper edge of the pan. Another means of fastening is afforded by a
hook which passes through a hole in a bracket on the other side of the pan.
The foot step is arranged as follows: From each side frame projects a slanting
bar fixed thereto or cast thereon and on its inner or under side formed with teeth
for a peg to take into which latter is on a lever pivotted to the foot step, which
with brackets or feet on the underside rests on the slanting bars and is kept in
the required position by the levers which are worked by an outside handle and
are pressed upwards by a spring so that the pegs are pressed into the teeth.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Gerard Wenzeslaus von Nawrocki in the Great Seal Patent
Office on the 17th November 1882.
GERARD WENZESLAUS VON NAWROCKI, Proprietor of the firm of J. Brandt &
G. W. v. Nawrocki, Patent Solicitor and Civil Engineer of 124, Leipzigerstrasse,
Berlin, Germany "IMPROVEMENTS IN CHILDREN'S CHAIRS." (A communication
from Louis Schmetzer of Rothenburg on the Tauber, German Empire)
This chair is so constructed that it may also be used as a childs go-cart with
casters. For this purpose the seat is fastened to the underframing so as to be
removable therefrom, and the legs, which are made to swivel on the upper part of

page_text: the under framing in the usual manner, are provided with casters which only
come into action when the chair is to be made into a go-cart. There is on the
under framing an open or three sided frame with a ring cushion attached thereto
and serving to hold the child when running. By uniting the seat cushion with the
lid for the closet the hole through the latter is closed and the seat cushion kept
securely in place. The chair is also provided with a foot step which can be shifted
in position according to the length of the child's legs. The closet pan is attached
to the seat so that it can be conveniently removed therefrom and for this purpose
a half round or bow shaped metal bar with spring and catch hook are provided at
one side of the closet opening, the hook corresponding with an opening in a
bracket on the pan and into which it is pressed by the spring.
Figure 1 of the accompanying drawings is a vertical section through a childs
chair constructed according to this invention, and Figures 2, 3, 4 and 5 are detail
views.
The legs a which may be provided with wheels b or not are as usual, by pivots c,
connected to the cast iron frames d and are kept in their normal extended or down
position by means of a cast iron holder f for each two legs, each holder being
jointed at one end to the upper prolongation a' of one leg and resting against the
upper prolongation a' of the other leg, as shown in full lines on Figure 1. On
raising these holders the legs spread out and the height of the chair is thereby
reduced as shown in dotted lines. In this position the casters g which are
connected to the side of the legs will touch the ground. The holders f one on
each side of the chair are at their upper ends united at top by a bent up part h¹ on
each side of the aforesaid threesided frame h for the ring cushion m Figures 1, 2
and 3; the seat is removably fixed to this frame h; for this purpose the seat
board is pushed back into and under the bent up parts h' as shown at figure 3,
and is kept in position in front by a hook 2 passing through an opening in the
frame and behind a spring catch h². The ring cushion m is fixed to this frame h
as stated and the child is tied into this cushion after the removal of the seat and
the raising of the chair legs to the dotted position; the chair will then be used as a
go-cart.
The seat board has the closet pan hole through as shown in Figure 1, and the
pan lid n¹ is directly connected to the seat cushion n. In this way the pan lid n¹
also serves as a means for securing the seat cushion n.
In order to regulate the height of the chair according to the size of the child a
special small table may be used as shown in Figure 5, a is the table which by
means of four iron brackets ẞ provided with holes and pegs, and by means of
corresponding holes in the frame & can be raised or lowered; the frame 8 is
connected to the U shaped bent bar h in the same manner as the seat board l¹
Figure 3. The form of the small table a is shown in dotted lines at Figure 4.
The ring m is in this case, not connected to the frame h but to the edge of the hole
in the table, and above it. According to another modification the frame h may be
open in front instead of behind in which case the footboard A may be used as a
seat when the child is tired of running. When the chair is not to be used as a
go-cart the table is removed and the seat refixed.
The pan p is made of tinned iron (instead of stoneware as heretofore) and has a
top edge bent over as shown in Figures 1 and 4. Stoneware pans easily break at
the edge and they can then not be fixed to the seat by the lugs and bars thereon;
the wooden lugs and bars are also done away with, as they swell when wet and
thus prevent the pan from being pushed in. In Figure 4 is shown from below the
mode in which the pan is fixed to the seat board . Instead of the wood lugs and
bars there is provided on one side a half round or curved inetal bar o which by
means of pegs is connected to the underside of the seat board a slight distance
therefrom; this distance corresponds with the height of the bent over top edge p¹
of the pan p; between the bar o and the seat board there is a spring o¹ which
rests against the upper edge p' of the pan p. Another means of fastening is
afforded by a hook 7 which passes through a hole in a bracket p² on the other side

page_text: of the pan p. Besides the book r there may be two hooks which bend over the
edge of the pan or the hook r may be omitted, and the hooks 7' be applied. The
pan p' with its curved edge is pushed under the bar o, the bracket p² is raised, so
that the bar enters the opening in the bracket, whereupon the pan is pushed back
by the spring o', so that the hook holds the bracket as shown in Figure 1. This
arrangement is very strong and admits of the pan being conveniently fixed.
The footstep is arranged as follows. From each side frame d projects a slanting
bar s fixed thereto or cast thereon and on its inner or under side formed with
teeth for a peg u to take into, which latter is on a lever v pivoted to the footstep t
which with brackets or feet on the underside rests on the slanting bars s' and is
kept in the required position by the levers which are worked by an outside
handle and are pressed upwards by a spring w so that the peg u is pressed
automatically into the teeth. The peg u may also be fastened directly to the
spring w. By the slanting position of the bars 8¹ the footboard is made adjustable
horizontally and vertically, while the peg u is not exposed to much strain.
When the chair is to be used for sitting on the seat is fixed to the under framing,
as described, but if it is to be used as a go-cart, the seat is removed, the legs a are
put in the dotted position as shown, so that they rest on the castors g, and the
child is tied into the stuffed ring m. The castors g permit of moving the go-cart
in all directions.
I claim as the Invention communicated to me,-
First. The arrangement of the removable seat and the mode of fastening it, as
set forth.
Second. The arrangement of the stuffed ring m on the under framing of the chair
for the purpose of using it as a go-cart.
