I ARMAND MANCHAIN of Geneva Switzerland manufacturer do hereby declare
the nature of said Invention for IMPROVEMENTS IN EXTENSIBLE FRAMES OR
STRETCHERS FOR PICTURES AND OTHER PURPOSES AND APPARATUS FOR OPERATING
BAME to-be as follows:-
"
The object of my invention is to offer to the painters, dealers of pictures and
others a system of an extensible frame the outside, of which does not differ from
the usual frames and which may notwithstanding be adapted to pictures of, different
sizes also applicable to stretchers.
Moreover my extensible frame is arranged so as to allow the artist to fix his
canvas or paper directly on the back of the frame after having adjusted the
latter to the desired.size by the aid of drawing pins and to stretch the same
strongly.
The artist may also vary at will, the size of the picture and of the frame while
he is painting or drawing thereon.
For those artists who do not like to do their work on framed canvas I have
combined an extensible frame on which the canvas is affixed in the usual-manner,
on the edges.
In the annexed-drawing Fig. 1 Sheet 1 shows the back and Fig. 2 the front of
my extensible frame arranged so as to allow the canvas to be affixed on the back
of the same, the same Fig. shows moreover a section through Y Z.
Fig. 3 shows the way in which the canvas is affixed on the frame and a section.

Fig. 4 is a section through UZ showing the movable arrangement of the corner A
as it is adopted for gilt borders or for borders which might be easily damaged by
the friction of the corner upon same.

Fig. 13 is a side view of the latter with a section through W-U. Fig. 14 is a
side view of one of the standards of the same after the frame has been taken
away. Lastly Fig. 15 shows a plan and a front view of the frame holder or stand
folded up.
My extensible frame is composed of the borders B and corners A which may be
more or less decorated and which are intended to cover the interruptions of the
borders B resulting from the opening of the frame. The pieces C which are affixed
on the back of the corners A are provided with slots F in which are screwed the
screws G which are fixed on the back of the borders B.
This arrangement allows the pieces C to be moved at will behind the borders B
and to maintain them in their respective position.
If the borders B are gilt or provided with delicate decoration, the corners A are
'made movable so as to be lifted up when the frame is being opened in order to
avoid any friction on the decorated parts.
The border D which is fixed on B is intended to work as a slide and to cover
the-interruptions of border B on the edge of the frame. If the frame is intended
to receive the canvas-on-its-back the section of the border B (Fig. 3) is provided
with a flange H over which the canvas E is stretched after having been affixed on
the back of the border B with the aid of drawing-pins K.
The groove J is intended to allow the brush to cover the canvas with colour up
to the edge without dirtying the frame, it allows moreover of the employment of
the same frame for a picture painted on cardboard, wood or other, material:
The canvas fixed on the frame as just described is stretched in the same manner
and with the aid of the same instrument as hereafter-described for the other
arrangement of the extensible frame.
The frame shown in Figs. 5 and 6 sheet 2 is arranged so as to bé covered
on its whole surface by the canvas.
The same is composed of the corners à on the back of which are affixed the
pieces c and of the borders b which are provided with slides in which the branches
of pieces 'c move.
The latter are provided with slots f in which the screws g are fixed on the
borders b and may be displaced at will and maintained with the help of their
screw nuts.

A metallic band a fixed on border b sliding over à covers the interruptions of
the edge of b.
This band & may at will be replaced by a wooden band d of the section shown
at Y Z Fig: 7 and which takes in a slide d arranged in the corner a
Fig. 7 shows the way in which the canvas t is fixed over the edge of the frame
By the aid of drawing pins 8.
The stretching apparatus shown in Fig. 8 is composed of right and left handed
screws screwed in two nuts i which are fixed on shoes h h formed so as to fit
into the groove of b in which slides the piece c
To obtain a very strong and regular stretching of the canvas the grooves in
which slide the pieces care provided with a scale numbered from the centre right
and left:
:
By means of this scale one can see if the distance m at top-coincides with the
distance n at bottom and this ensure the frame being set square:
The apparatus shown in Fig. 9 is intended to open the frames (especially those
of large size) without straining them. Under the two boards p.slide in Buitable-

provided in the extremeties of the pieces o.
When the apparatus is placed on the back of the frame in the position shown in
Fig. 9 the sides B of the frame can be moved from or to one another very easily
by turning the screw r.
The apparatus is then placed so as to remove the two other sides of the frame.
The apparatus shown in Fig. 8 may also be provided as shown in Fig. 11 Sheet 1
with screw nuts P' P₁ allowing the same being fixed upon the bearings M M as
shown at Fig. 12 and to give to the frame fastened between the shoes H H also
shown at Fig. 12 the desired inclination.
The bearings M may be fixed upon the table 'N by means of hinges O to be
folded down as shown in Fig. 15.

The arrangement shown in figure 11 to 15 may be used for holding water
painting blocks.
