Improvements in Picture Frames.
I, RUDOLPH LIEBMANN, a citizen of the United States of America, residing
at 1200 Madison Avenue in the City, County and State of New York, in the
United States of America, Manufacturer, 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 has reference to improvements in metallic picture frames, and
especially to miniature frames, it having for its object to provide frames permitting
the interchange of pictures and to facilitate the manufacture of such frames. To
this end my invention consists essentially in a metallic picture frame composed of
an open flanged front, a flanged back and an intermediate transparent covering for
the picture; said front having one of its flanges bent down upon the transparent
cover to form the opening for the insertion of the picture, and the remaining
flanges closed over the flanges of the back.
The nature of my invention will best be understood when described in connection
with the accompanying drawings; in which:
Fig. 1 represents a perspective view of a picture frame embodying my
invention.
Fig. 2 is a perspective of the front of the frame.
Fig. 3 is a perspective of the back.
Fig. 4 is a longitudinal section of the complete frame.
Fig. 5 is a transverse section of the same; said last four figures being drawn to
a smaller scale than Fig. 1.
Similar letters and numerals of reference designate corresponding parts
throughout the several views of the drawings.
Referring to the drawings, the letter a designates the front of the picture frame,
which is made open, as usual, and is provided with flanges 1. 1, at opposite sides,
and with flanges 2 and 3 at top and bottom. The several flanges are first bent at
substantially right angles to the body of the front a, and into said front is placed
a transparent covering for the picture, which covering is preferably composed
of a film of celluloid, or like flexible, transparent material, which is not likely to
be broken when the parts of the frame are closed in the dies. After the insertion
of the transparent covering b, one of the end flanges 2 is bent down upon the film
for the purpose of subsequently forming with the back c, the opening 4 for the
insertion of the picture. The back c is provided with two side flanges 5, 5 and a
bottom flange 6, all of which flanges are made substantially L shape.
The back e is placed into the front and the flanges 1 and 3 of the front are closed
over the flanges 5 and 6 of the back, as shown in Figures 4 and 5. The back may
be provided with a suitable supporting or suspension device d, as shown in
Figures 1 and 4, or it may be provided with a suitable attaching pin. In practice,
I form an opening 7 in the back, which will enable the picture e (shown in dotted
lines in Figures 4 and 5) to be removed by the use of a pin or like device, or by
hand..
While I have herein shown the flanges of the front a made continuous, it is
evident that the front could be formed with narrow ears in place of such continuous
flanges. It is also evident that the frame could be made from celluloid or other
pliable material, instead of. sheet metal.

page_text: Heretofore, picture frames have been invariably provided with glass fronts
inserted after the completion of the frame. The glass being loose was liable to
slip out, and also liable to break. Furthermore, the glass could not be inserted
prior to the closing of the frame in the dies. With the use of a celluloid or like
film, the frame is lighter, can be closed in dies, and there is no danger of breakage,
besides, the tone of the picture is improved. The film is firmly held between the
front and back, and cannot slip out.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A metallic picture frame composed of an open flanged front, a flanged back,
and an intermediate transparent covering for the picture; said front having one
of its flanges bent down on the covering to form an opening for the insertion of
the picture, and having the remaining flanges closed over the flanges of the back,
substantially as described.
2. A metallic picture frame composed of an open flanged front, a flanged back,
and an intermediate transparent film held between the front and back; said front
having one of its flanges bent down on the film to form an opening for the insertion
of the picture, and having the remaining flanges closed over the flanges of the
back substantially as described.
3. A metallic picture frame composed of an open flanged front, a flanged back
having an opening therein to permit of the removal of the picture, and an
intermediate transparent covering held between the front and back; said front
having one of its flanges bent down on the covering to form an opening for the
insertion of the picture, and having the remaining flanges closed over the flanges
of the back, substantially as described.
4. A metallic picture frame composed of an open flanged front, a flanged back
provided with a supporting or suspending device, and an intermediate transparent
covering held between the front and back; said front having one of its flanges
bent down on the covering to form an opening for the insertion of the picture, and
having the remaining flanges closed over the flanges of the back, substantially as
described.
