IMPROVEMENTS IN STANDS FOR CHILDREN'S CHAIRS
Year: 1878

page_text: LETTERS PATENT to William Keen, of 69, Scrutton Street, Curtain Road,
London, Chair Manufacturer, for the Invention of "IMPROVEMENTS IN STANDS
FOR CHILDREN'S CHAIRS."
Sealed the 13th August 1878, and dated the 15th February 1878.
PROVISIONAL SPECIFICATION left by the said William Keen at the
Office of the Commissioners of Patents on the 15th February 1878.
WILLIAM KEEN, of 69, Scrutton Street, Curtain Road, London, Chair Manu-
facturer. "IMPROVEMENTS IN STANDS FOR CHILDREN'S CHAIRS."
This Invention of improvements in stands for children's chairs relates to children's
chairs that are constructed in two parts, the chair proper and the stand or table upon
which the chair proper is fastened, usually by a thumbscrew, the stand being made
with four legs, and consists in making the ordinary stand or low table upon which a
child's chair is usually placed to form a high chair, to fold up so that the chair may be
used as a high chair or a low chair, and yet occupy the same area of space.
I
accomplish this by making one side of the stand top or table to pivot to two of the
legs by a pin in each leg, or by hinges, or other suitable means; the opposite side is
kept up level in its normal position by catches or spring bolts or other similar
or suitable devices fixed to the two other or opposite legs.
The action of the chair stand in doubling up is in this manner (supposing
the chair to be fixed upon the stand with the thumbscrew and in use as
a high chair)-When it is desired to make it a low chair the catches or bolts,
preferably fitted on the two back legs, are withdrawn out of action, and the table
top, with the chair attached, pivotting on the pins or hinges falls down at the same
time, the stand folding or falling over forwards, the four legs then project
horizontally, and the four bottoms of the legs project to the back of the chair, the
table top of the stand still retaining its horizontal plane, but at a lower level, and
nearly approaching the floor. The chair will then rest upon the floor, supported by.
the two front legs of the stand, and not standing vertically, but lying parallel upon

page_text: the floor. To these two legs I attach four wheels or rollers, and the chair is then
in its low condition a carriage for the child to push about or to be wheeled
about in.
When the chair is restored to its normal or high position, these wheels or
rollers, when the chair stand legs are vertical, are entirely off the floor, and the chair
stand rests upon the end of the four legs.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Keen in the Great Seal Patent Office on the 13th August
1878.
WILLIAM KEEN, of 69, Scrutton Street, Curtain Road, London, Chair Manu-

This Invention of improvements in stands for children's chairs relates to children's
chairs that are constructed in two parts, the chair proper and the stand or table
upon which the chair proper is fastened, usually by a thumbscrew, the stand being
made with four legs, and consists in making the ordinary stand or low table upon
which a childs chair is usually placed to form a high chair, to fold up so that the
chair may be used as a high chair or a low chair, and yet occupy the same area of
space. I accomplish this by making one side of the stand top or table to pivot to
two of the legs by a pin in each leg, or by hinges, or other suitable means; the
opposite side is kept up level in its normal position by catches or spring bolts or
other similar or suitable devices fixed to the two other or opposite legs.
The action of the chair stand in doubling up is in this manner (supposing the
chair to be fixed upon the stand with the thumbscrew and in use as a high chair) :-
When it is desired to make it a low chair the catches or bolts, preferably fitted on
the two back legs, are withdrawn out of action, and the table top, with the chair
attached, pivotting on the pins or hinges falls down at the same time, the stand
folding or falling over forwards, the four legs then project horizontally, and the four
bottoms of the legs project to the back of the chair, the table top of the stand
still retaining its horizontal plane, but at a lower level and nearly approaching the
floor. The chair will then rest upon the floor, supported by the two front legs of the
stand, and the stand not standing vertically, but lying parallel upon the floor. To
these two legs I attach four wheels or rollers, and the chair is then in its low con-.
dition, a carriage for the child to push about or to be wheeled about in.
When the chair is restored to its normal or high position, these wheels or rollers,
when the chair stand legs are vertical, are entirely off the floor, and the chair stand
rests upon the ends of the four legs.
In the Drawings accompanying and forming part of this Specification the like
letters indicating like parts.
Figure 1 shows the stand folded down with the chair on it at its lowest
elevation.
Figure 2, the stand at its highest elevation with a chair on it.

Figure 4, under side of the platform of the stand on which the chair rests to
show the action of the spring locking the levers into the legs of the stand when the
table is at its highest larger scale.

drawing the spring back, larger scale.
a, the platform of the stand; b, the front legs of the stand; c, the-back legs of
the stand; d, the levers or catches entering the legs c in small recesses; the levers
are fulcrumed at d¹, protected or held in place by plates d, the notches d³ working
on the pin d, acted upon by the spring d³, and drawn out of the notches in c by
the finger piece do.
The chair stand platform is pivotted or hinged on the line a, x, a, see Figure 2,
and shown in action at Figure 3. When the chair is pulled it brings the platform
with it, and the levers d acted on by the spring d³ enter into the legs c, and hold up
the stand and chair. When the finger draws back the spring the stand and chair
fold up to the position shown in Figure 1.
Having now described and particularly set forth the nature of the said Invention
and the manner of carrying the same into effect, I would have it understood that
what I claim is,―
First. In a stand for a childs chair the method of folding up the platform within
the legs, substantially as described.
Second. The spring, substantially as described, for holding up the platform of the
stand for a chair to be used as a high chair.
Third. The method described of hinging or attaching and folding up a chair stand,
so that when folded up with a chair in it, or standing up for use with a high chair,
it shall occupy nearly the same area on the floor.
In witness whereof, I, the said William Keen, have hereunto set my hand
and seal, this Twelfth day of August, in the year of our Lord One
thousand eight hundred and seventy-eight.
