I, RICHARD CHOINANUS of Berlin, German Empire, Merchant do hereby declare
the nature of my Invention for "IMPROVEMENTS IN STANDS OR SUPPORTS FOR
PICTURES MIRRORS AND OTHER SIMILAR ARTICLES" and in what manuer the same
is to be performed, to be particularly described and ascertained in and by the
following statement :—
My Invention relates to easels or portable stands for pictures, maps, mirrors and
other articles.
In the accompanying Drawings which illustrato the Invention, Fig. 1 is a back
view and Fig. 2 a vertical section of a stand, while the other Figures represent
details and modifications.
.
The Invention consists in a special appliance or mechanism for connecting the
two parts A A' of the frame which holds the picture, mirror or other article.
Instead of a pair of clamps mounted on a rod and held together by a spring, and
a folding stay or leg, as frequently used for the purpose of holding together the
two halves or parts of the frame and supporting them, I employ a spring B pivoted
to the halves À, A' of the frame and capable of being fixed in its upright position
(perpendicular to the plane of the frame A A¹) by any suitable means.
The plates or clamps A A¹ are connected with the extremities of the spring
stay B by means of hinge joints C, C¹, which allow the stay B to be placed
perpendicularly to the plates A A', as shown in Fig. 2, or turned down as shown
in Fig. 1. The elasticity of the stay B tends to draw the clamps A A¹ against each
other, so that a plate, mirror or sheet placed between the turned up edges or hooks
of the parts A A' will be firmly gripped by the same,
In order to fix the stay in its upright position, tho lower hinge C is constructed,
as shown in detail by Fig. 3 and 4, Fig. 3 representing the upright position, and
Fig. 4 the folded position.
The part of the stay B situated in the hinge piece C is surrounded by a helical
spring babutting with its upper end against a collar a of the stay B, while tho
lower end is fixed to the hinge piece.
The extremity of the rod forming the spring stay B has a projection c, which
fits into a recess d of the hinge piece C', and is drawn into the same by the sınall
spring, after the stay has reached its upright position.

page_text: The helical spring enclosed in the hinge piece C, therefore only serves to fix the
stay in its upright position, while the plates A, A' are held together by the
clasticity of the stay B.
In the modified form represented by Fig. 5 and 6, the hinge piece is replaced by
the guides e, e³, and the wire or rod forming the stay is bent at fand f',
If the stay is turned into the upright position represented by Fig. 5, the
parts ff enter the dished parts g, g' of the plate A', and thereby fix the stay in
its upright position.
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
A spring pivoted to a pair of clamps holding the plate, picture, mirror or other
article, on opposite sides, said spring boing adapted to draw the two clamps
together, and to serve as a stand, when turned up, substantially as described.
