Improvements in Alterable Children's Chairs.
We,
WILLIAM SEATON MCLENNAN, of 222 Whitehill Street, in the County
of the City of Glasgow, North Britain, Chair Manufacturer, and THOMAS MORTON,
of 145, Finlay Drive, in the same County, Foreman Chair Maker, do hereby
declare the nature of this invention to be as follows, that 15 to say :—
Our said invention relates to alterable children's chairs such as are known as
American adjustable or four-position chairs, and has for its object to improve the
construction of such chairs in a manner to provide for certain additional alterations
or changes of position of an advantageous kind.
In carrying out our invention we adopt any suitable known construction for the
lower legs or supporting parts of the chair, with known devices for altering the
positions of those parts and for locking them in any of their several positions.
We further construct and connect the back of the chair and other parts so that the
back can be more or less inclined when wished. For this purpose the back. is
jointed to the seat or to parts adjustable on the seat, and has the side arms
jointed to it. In one modification the front ends of the side arms are jointed to the
upper ends of side bars which are, ordinarily, nearly vertical, and are jointed to the
sides of the chair. The side bars are also connected to a foot rest in such manner
as to raise the foot rest when the back is inclined backwards. Any simple device
may be provided for locking the parts in any desired position.
In another modification the side arms are each in one piece with or fixed to a bar
provided with a pin which works in a groove or slot in the side of the chair seat,
one edge of the groove or slot being notched. A spring is applied to press the
pin into a notch; and to change the position of the parts the arms are depressed or
moved to free their pins from the notches and are then moved backwards or
forwards as required. Instead of arranging a foot rest to be movable in the manner
herein before described, a slide may be fitted to the seat to be drawn out when the
back is inclined backwards, or at other times if desired. Or instead of a sliding
piece, a board may be hinged to the front of the seat so that it can be turned
up when required, such board being either separate from or having the foot
rest.fixed to its lower edge.

Improvements in Alterable Children's Chairs..
We, WILLIAM SEATON MCLENNAN, of 222, Whitehill Street, in the County of
the City of Glasgow, North Britain, Chair Manufacturer, and THOMAS MORTON,
of 145, Finlay Drive, in the same County, Foreman Chair Maker, 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, that is to say:
Our said invention relates to alterable children's chairs such as are known as
.*.

page_text: American adjustable or four-position chairs, and has for its object to improve
the construction of such chairs in a manner to provide for certain additional
alterations or changes of position of au advantageous kind.
In carrying out our invention we adopt any suitable known construction for the
lower legs or supporting parts of the chair. We further construct and connect
the back of the chair and other parts so that the back can be more or less
inclined when wished, the back being jointed to the seat or to parts adjustable
on the seat and having the side arms jointed to it. The front ends of the side
arms are jointed to the upper ends of side bars which are jointed to the sides
of the chair. The side bars are also connected to a foot rest in such manner as
to raise the foot_rest_when_the_back-is-inclined backwards. Any simple device
may be provided for locking the parts-in-any desired position.
In another modification the side arms are each in one piece with or fixed to a side
bar provided with a pin which works in a notched groove or slot and a foot rest
may be provided either in the form of a sliding piece fitted to the seat, or a board
may be hinged to the front of the seat, such board being either separate from or
having the foot rest fixed to its lower edge.
And in order that our said invention and the manner of performing the same may
be properly understood we hereunto append a sheet of explanatory drawings to
be hereinafter referred to and showing our improvements.
Figure, 1, on the accompanying sheet of drawings is a side elevation; and
Figure, 2, a back elevation, showing one modification of our improved chair.
Figure, 3, is also a side elevation of the same modification but with the parts in a
different position.
Figures, 4, and, 5, are side elevations showing other medifications of our
improvements.
In these drawings the same reference letters are used to mark the same or like
parts wherever they are repeated.
As shown in the drawings we adopt a well known construction for the lower
legs or supporting parts, A, of the chair, with known devices, B, for altering the
positions of those parts and for locking them in any of their several positions.
We further construct and connect the back, C, of the chair and other parts so that
the back can be more or less inclined when wished. For this purpose the back, C,
is jointed at, D, to the seat, E, and has the side arms, F, jointed at, G, to it. In
the modification shown in Figures, 1, 2, and 3, the front ends of the side
arms, F, are jointed to the upper ends of side bars, H, which are, ordinarily,
nearly vertical, and are jointed at, J, to the sides of the chair. Below
the joint, J, the side bars, H, are connected together by a board, K, the
bottom of which forms a foot rest, so that the board and foot rest, K, are raised
when the back, C, is inclined backwards, in which position the parts are shown in
Figure, 3. On each side of the seat, E, guards, L, are fixed to give lateral
support and guards, M, are also fixed to the back, C, at the upper parts of its
sides. For locking the upper parts in any desired position a bar, N, is hinged to
the back,, of the chair and has notches, P, formed at its other end which can
engage with a pin, Q, in the side of the seat, É.
With the parts in the positions in which they are shown in Figure, 3, the chair
becomes a kind of cradle capable of rocking longitudinally and of carrying a
child in a nearly horizontal position. With the upper parts as shown in Figure, 3,
but with the legs, A, turned down more or less so that the chair may rest on their
ends, it becomes a stationary crib or child's bed, which can be adjusted at different
heights.
A blade
In the modifications shown in Figures, 4, and 5, the side arms, F, are each fixed
to a bar, H, provided with a pin, R, which works in a groove or slot, S, in the side
of the chair seat, E, one edge of the groove or slot being notched.
spring, T, is applied to press the pin, R, into a notch; and to change the position
of the parts the arms, F, are depressed to free their pins, R, from the notches
and are then moved backwards or forwards as required. Instead of arranging a

page_text: foot rest (K) to be movable in the manner herein before described, a slide, U, may,.
as shown in Figure, 4, be fitted to the seat, E, to be drawn out when the back, (
is inclined backwards, or at other times if desired. Or as shown in Figure, 5,
instead of a sliding piece (U) a board, W, may be hinged to the front of the
seat, E, so that it can be turned up when required, in which position it can be
secured by causing the end of a small sliding bolt, X, to enter a notch, Y, in the
top edge of the board, W. A foot rest, K, is shown as being fixed to the lower
edge of the board, but such foot rest may be separate from the board if desired.
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 an American or alterable child's chair combining the adjustable legs and
mechanism thereof with upper parts jointed to the body of the chair and to each
other to enable the back to be more or less inclined and other parts altered in
position substantially in the manner and for the purposes herein before described.
2. In an American or alterable child's chair, hinging the back to the seat or to.
parts adjustable on the seat, and hinging the side arms to the back and to the upper
ends of side bars jointed to the sides of the chair at the front and provided with a
foot rest with means for locking the parts in any desired position substantially as
and for the purposes hereinbefore described and as shown in Figures, 1, 2, and 3, of
the accompanying drawings.
3. In an American or alterable child's chair, a movable back having jointed to.
it side arms made in a piece with or fixed to side bars adjustable at their bottoms
on the sides of the chair seat, substantially as and for the purposes hereinbefore.
described and as shown in Figures, 4, and 5, of the accompanying drawings.
