GEORGE MONTEITH DODSHON, 71, Myddelton Square, E.C. in the County of
London, Artist. I do hereby declare the nature of this invention to be as follows:
My invention relates to a method of making a cheap and portable frame which
can be used as a substitute for a gilt frame for oil paintings, enabling the artist to
see the effect of his work without the cost and trouble of framing, and the frame
can be used in all cases where it is required to show pictures to advantage.at a
small cost. In carrying out my invention I proceed in the following manner.
Suppose it is intended to form a frame of the size known as a two inch frame,
I should take a long strip of straw board, card board, mill board, or thin metal,
six and a quarter inches wide, and cut four parallel V shaped grooves along its
entire length, the first groove half an inch from the edge, the next half an inch
from the first, and on the other side of the card, or straw board, this groove is the
only one on the other side of the board, the third groove is three quarters of an
inch from the second, the last groove is two and a quarter inches from the third
groove; the card or other board is next bent and formed into a moulding including
the mat this moulding can now be cut into the desired length, according to tho
size of the frame required, when the four pieces are cut off the ends are cut in
such a manner, and V grooves made, as will form a triangular and square flap on
cach end, and also allow of the angles and mitreing of the frame being formed,
the said flaps being for the purpose of holding the frame together by means of
ordinary paper fasteners. In the case of large fraines the moulding can be made
up of pieces. The frame is attached to the wedge-wood, canvas frame, or
pannel etc., by means of drawing pins or tacks driven through the three quarter,
and half inch divisions of the board mentioned above. The frame may be made
more serviceable by pasting a fine canvas over the inner side of the card or straw
board. When not required as a frame the four parts can be laid out flat and thus
become very portable. I do not confine myself to the particular moulding herein-
before described as many different forms can be made by damping the board and
pressing in moulds, or a variety of forms out of the flat.

COMPLETE SPECIFICATION.
Improvements in Picture Frames.
I, GEORGE MONTEITH DODSHON, of 71 Myddleton Square, Clerkenwell, in
tho County of London, Artist, 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 :——
My invention relates to picture frames, its object being the construction of a
cheap and portable frame which can be used as a substitute for a gilt frame and for
ordinary wooden and other frames and can if desired be so made as to collapse or
Pine Ad

page_text: flatten out for convenience of transport. Preferably employ millboard, straw-
board or the like for frames constructed according to my invention, and I may
employ other material, such for instance as sheet metal.
In the accompanying drawings, which illustrate by way of example one
construction or pattern of my improved picture-frame,
Fig. 1 is a perspective front elevation of the frame,
Fig. 2 is a perspective rear-elevation thereof, with a picture therein,
Fig. 3 is a plan of the top member of the frame, laid Hat, prior to being
incorporated with the frame;
Fig. 4 is a similar view of a side member of the frame,
Fig. 5 is a perspective front view of one of the angles of the frame partly
sectional,
Fig. 6 is a similar view of one of these angles as seen from the back of the
frame, and
Fig. 7 is a perspective view of a detail hereinafter referred to.
Figs. 1 and 2 are drawn to a smaller and Figs. 5, 6 and 7 to a larger scale than
that of Figs. 3 and 4.
Like letters indicate like parts throughout the drawings.
A and B are strips of sheet material. A' A' A' A are parallel grooves or
depressions made in the faces of the strip A by a knife or other tool. The
grooves A A A³ are on one face of the strip, and the groove A is on the other.
B1 B2 B3 B are similar grooves similarly situated in the strip B.
The strips thus grooved will readily fold into such a form of cross-section as is
indicated by the section-lined portion of Fig. 5 or Fig. 6. The grooves A¹ A²
A³ A' are made in order to facilitate the bending of the strip at the proper places;
they and other similar grooves hereinafter referred to may be dispensed with, if
the material employed be one which can be bent to the desired angle along the
desired lines without them. The strip is used in lengths proportionate to the
desired dimensions of the sides of the frame; each strip is shaped at each end in
some such manner as is indicated in Fig. 3 or Fig. 4. In these examples
triangular flaps A are provided at each end of the portion A of the strip A, a
groove A being made in the strip at an angle to the grooves A2 and A³ so that
each flap may turn about its line of junction with: the strip as on a hinge. On the
triangular flap A³ is a rectangular extension A³, a groove A³ constituting a
common boundary between them and enabling the extension to turn upon the flap.
Triangular flaps B and grooves B' are provided at each end of the portion B
of the strip B, but the flaps B have no rectangular extensions such as A.
A small rectangular extension B10 is provided at each end of the portion B" of the
strip B and a large one B at each end of the portion B³ thereof, grooves B14
and B being provided at the junction of the flaps B1 and B2 with the strip.
To make a rectangular frame, two strips such as A and two such as B are folded
along their grooves and put together at right angles in the manner iudicated in
Figs. 1, 2,5 and 6 so that the parts A and B lie flat against each other, the exten-
sions A lie flat against the part B₁s of B and the extensions B10 B1 lie against the
parts A and A respectively; the parts A A B B being attached respectively to
the parts B B A" A13 by paper fasteners C which may be of the ordinary kind or
may be specially ornamented. Other fastenings may be used if desired instead of
the fasteners C. The grooves A are so situated and the parts A B so shaped
that when the frame is built up sufficient clearance will exist between the parts A
and A13 for the passage of the part B. Similar clearance may be provided
wherever necessary. The parts A and B" fold down their centres respectively
into two parts A and A, B17 and B1, the portions A16 A18 B1 B form a
rebate in which the picture 1 fits, and the parts A B form beads against which
the face of the picture rests. The ends of the parts A B can be bevelled to
butt against each other as in Fig. 5 or interlocked one in the other as in Figs. 6
and 7. Fig. 7 shows one end of oue of these parts B1 thiuned to engage with the
other end of the companion part which also is shown correspondingly..but

page_text: reversely thinned and bevelled. The parts A" A8 and also the parts B BB can
be fastened together by paper fasteners or otherwise, or when the picture.is placed
in the rebate aforesaid, nails can be driven through these parts into its edge.
The position of the grooves on the strips and the dimensions and relative
disposition of the several portions thereof can be varied as may be desired, in
accordance with well-understood geometrical principles to enable different sizes
and patterns of frames to be produced, and the invention is applicable to other than
rectangular frames. For example by adding a strip along the side of the
portions A and B" flaps may be provided to serve for covering part or the
whole of the back as may be desired. By suitably disposing the grooves and
extensions of a strip, a single strip will suffice to form a complete frame.
Ornamental designs can be embossed or otherwise placed by way of ornament
upon the strips.
It is found that the natural tint of strawboard which as aforesaid can be used
for the manufacture of my improved frames is particularly well suited for pictures
done in colour. But if it be desired to decorate the frames by means of plush or
other fabric, such decoration can be very neatly effected by laying a suitably.
shaped piece of plush upon the strips, say on the parts A16 A of the strip A,
straining it tightly round the ends thereof and tacking or otherwise securing its
edges to the unexposed faces of the strip. To strengthen the strips at the folds
strips of flexible fabric such as E (Fig. 4) can be secured thereto at the grooves.
Or instead of using grooves the several parts of the strip may be cut completely
through as for instance where the grooves are indicated in the drawings, and
rejoined by such strips as E.
Under the term "picture frame" herein employed I of course include mirror
frames.
Having now particularly described and ascertained' the nature of the said invon-
tion, and in what manner the same is to be performed, I declare that what 1
claim is;-.
1. In a picture-frame a strip or piece or two or more strips or pieces of sheet
material with or without grooves or channels therein shaped and disposed sub-
stantially as and for the purpose hereinbefore described.
2. A collapsable picture-frame, substantially as hereinbefore described.
3. A strip such as is claimed in Claim I wherein the joints at the folds or bends
are made by or are strengthened by pieces of flexible material substantially as and
for the purpose described.
4. A picture-frame with the parts at and adjacent to its angles constructed
substantially as and for the purpose herein before described.
5. A strip of sheet material with or without grooves or channels therein shaped
substantially as and for the purpose described and illustrated in Figures 3 and 4
of the accompanying drawings.
6. A picture-frame constructed substantially as and for the purpose described
and illustrated in the accompanying drawings.
