Improvements in Chairs.
I, GEORGE ARBUTINOTT SMITH, of Alberni, in the County of Vancouver,
Province of British Columbia, Canada, 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 relates to chairs, and has for its object to provide a chair which
can be readily converted into a child's chair. A further object is to provide a
chair which is simple in construction, of few parts and which can be manufactured
at a moderate cost.
To these ends the invention consists in a chair, constructed substantially as
hereinafter illustrated and described and defined in the appended claims.
Referring to the drawings, in which similar letters of reference indicate
similar parts.
Figure is a view in perspective of a chair constructed in accordance with
this invention, showing the seat in its elevated position, adapting it for the use
of a child.
Figure 2 is a top view thereof, partly in section.
In the drawings, A represents a chair of any usual or preferred construction,
having an adjustable seat portion A. The sides of the seat portion A¹ are cut
away or recessed, forming side flanges a, which match with the corresponding
flanges a¹ formed on the sides A2 of the chair A, the construction and arrangement
being such that when the seat portion A is in its lowered or normal position,
the chair has the appearance of an ordinary chair.
Upon the under side of the edges of the sides A2 and the seat portion A are
secured clips in which are pivoted the rods B, which are preferably arranged
as shown in Figure 1, two being on each side of the seat A. By means of this
construction, the seat A is always maintained in a horizontal position.
Upon each side of the seat A', and adjacent to the rear edge is fixed a spring
catch C, having a hooked end, which is adapted to enter a notch C¹ formed
in the lower cross-bar C2 of the chair back, and engage the back of said cross-bar,
by which means the seat A' is firmly held in its raised position.
The operation of the improved chair is believed to be easily understood from
the above description, and further detailed description thereof is unnecessary.
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. A chair, comprising a chair frame, a vertically adjustable seat portion
connected therewith, and means for retaining the said seat portion in its raised
position, substantially as described.
2. A chair, comprising a chair frame, a vertically adjustable seat portion, a
series of rods pivotally connected with said frame and said seat portion, and means
carried by said seat portion and adapted to engage with the chair back, for
retaining the said seat portion in its raised position, substantially as described.

page_text: 3. A chair, comprising a chair frame, a vertically adjustable seat portion, the
sides of said seat portion being recessed, forming flanges; corresponding flanges
on said frame, matching with the flanges of said seat portion; a series of parallel
rods pivotally connecting the seat portion with the said frame, and a spring
catch carried by said seat portion, and adapted to engage with the chair back,
whereby the said seat portion is retained in its raised position, substantially as
described.
Dated this 8th day of August 1899.
