WILLIAM WEEKes, Artist, 21, Oppidans Road, Primrose Hill, N.W.,
WILLIAM AUGUSTUS KEMM, Electrician, 21, Oppidans Road, Primrose Hill,
N.W., do hereby declare the nature of this invention to be as follows:-
-
The invention claims a frame able to be adjusted to fit any rectangular size
of canvas or panel up to nearly twice the size of frame before opening or extend-
ing for example, a frame 17 inches by 14 inches (being its smallest dimensions
will extend its sides independently to one another to fit any size of canvas or
panel whatsoever to 33 inches by 27 inches, or again, a frame 30 inches by
20 will fit any size to 60" by 40%.
Frames made in metal or wood and gilded or painted.
The frame made in sheet metal is worked by drawing or sliding the grooved
sides out which lap over one another (handles fixed at each corner) to the required
size, and fixing the said frame into position by means of thumb screws locking
the strengthening bars or border surrounding the back of the said frame, and
by springs holding each corner of canvas stretcher thus preventing the canvas
from falling out when fixed into position.
The extension frames made in wood claim the same capabilities for taking
any size of canvas or panel as the metal frames described; the method of extend-
ing being as follows:
The four sides being grooved to slide out from the centre on a block at the
back of frame, bringing the said block into view as the frame is pulled out
and fixed into the required position by thumb screws locking brass strips together
at back.

WILLIAM WERKES, Artist, 21, Oppidans Road, Primrose Hill, N.W., and
WILLIAM AUGUSTUS KEИM, Electrician, 21, Oppidans Road, Primrose Hill, N.W.,
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:

page_text: of canvas panel or mounted drawing, up to twice the size of frame betore open-
ing; for example, a frame 17 inches x 14 inches (being its smallest dimensions
will extend its sides independently to one another to fit any size of canvas panel
or mounted drawing whatsoever to 34* × 28" or one frame 30" x 20" will fit
any size to 60" x 40".
Frames can be made in any metal, or wood, and gilded or painted.
The frame made in sheetmetal is worked by drawing or sliding the grooved
sides out which lap over one another to the required size and fixing the said
frame into position by means of thumb screws locking the strengthening bars
or border surrounding the back of the said frame and by springs holding each
corner of canvas stretcher panel or mount thus preventing the picture from
falling out when put in position.
The drawings annexed, Sheet I, Fig. I, shows side elevation of frame.
Fig. II the front; the extensible sections in dotted lines.
Fig. III is a section through frame the sides lapping over marked D and an
additional groove arranged to prevent the front from rubbing on the section that
slides out from behind.
Fig. IV shows back of frame and brass rods B which lock frame in position
with thumb screws, A. Springs for holding picture in the frame marked C.
METHOD No. II (IN WOOD).
The extension frame made in wood claims the same capabilities for taking
any size of canvas, panel, and the like as the metal frame described in Method I.
The arrangement of sliding out being as follows:-
The four sides are grooved at the back to slide out from the centre on a block
at the back of frame bringing the said block into view us the frame is pulled
out and the whole fixed into position by thumb screws marked A, on drawing
Sheet 2 Fig. 5, which lock brass or iron strips (marked B) together at the
back of frame.
The four sliding corners of frame can also be made in metal.
The picture is held in frame by means of springs or catches, C, as in Method I.
Fig. 6 shows a section through frame.
The frame being composed of any smooth sheet metal can be made to any
bevel, the jointa at each corner being soldered together.
Fig. 2 shows the front view of frame when closed in, the given size of frame
as an example being 14 inches by 14 inches inside dimensions. The brass rods:
marked,B Fig. IV surround the back of frame and are fixed at each corner to
brass legs about one inch long soldered and rivetted to the frame. On pulling
the opposite sides independently to one another to their full extremities by the
brass rods B the frame is extended to twice its length and breadth namely to
28 inches by 28 inches thus bringing the sections which slide behind the front
sections into view, the back sections being marked by dotted lines Fig. 2. The
sides of the front sections fold or lap over for the back sections to run in, shown
at D Fig. III; there is also an extra strip soldered at D to form the side border
to the frame.
In Figs. 3, & 4, B shows the brass rods, one rod sliding into the other and 4
fixed at any point by thumb screws marked A, which lock the outside rods to
the rods sliding inside. The picture is held in frame by an angle piece of the
same metal soldered on the back sections shown on Fig. 3, and by the springs at
each corner of the frame marked C, Fig. IV. When the frame is extended the
sections are prevented from being drawn completely apart by a collar on the 5
ends of the brass rods.
METHOD 2 (IN WOOD).
Fig. 5. The drawing shows a plan of frame made in wood and metal fittings,
the example size given being 2 feet 6 inches by I foot R inches autoida
14

page_text: come into view as the sides are drawn out in the centres of the four sides of
the frame, the said block being grooved into the front sections of the frame as
shewn in section Fig. 6. Fig. 5. B represents the said brass or iron strips
which surround the back of frame and lock at any point by thumb screws
marked A, the four front sliding sections to the said grooved block. The inside
dimensions of frame given Fig. 5, being 20 inches x 20 inches will extend to
38 inches x 38".
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that
what we claim is:-
A frame able to be adjusted to extend both in length and breadth to fit any
mounted picture up to twice the smallest size of frame.
