IMPROVEMENTS IN PICTURE FRAMES
Year: 1885

page_text: I FREDERIC JAMES EGERTON HINE of Corporation Street Birmingham in the
County of Warwick Picture Dealer do hereby declare the nature of my said
invention for IMPROVEMENTS IN PICTURE FRAMES to be as follows:-
:-
The object of this invention is to construct Picture frames so that they will
expand to nearly or quite double their original dimensions. This is effected by
means of a reverse action (or double) screw fitted into a groove or channel in the
back of each side of the frame and running lengthwise within it.
The frame is cut through in the centre of each of its sides and each side is held
together and supported in its expansion by a metal bed in which it slides being
held and guided by grooves and by the double screw.
The double screw is held in position by and revolves within a metal centre-piece
which is fixed into the centre of the metal bed before referred to.
On the face of the centre-piece (which projects slightly in front of the frame) is
fixed a thin "centre section" piece resembling the frame and of sufficient length to
cover the opening caused in the side of the frame in its expansion.
By expanding the frame as above described the extension is always equi-distant
from the centre and the "centre section" always retains its central position.
The action of expansion is brought about by simply pulling the opposite sides
of the frame in order to make it wider or higher as required.

Improvements in Picture Frames.
I FREDERIC JAMES EGERTON HINE of Corporation Street Birmingham in the
County of Warwick Picture Dealer, do hereby declare the nature of my said
invention for IMPROVEMENTS IN PICTURE FRAMES, and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement, reference being had to the accompanying drawings and to the
letters and figures marked thereon:-
The object of this invention is to construct picture frames so that they will
expand to nearly or quite double their original, interior dimensions in either width
or height or both combined. This is effected by means of a reverse action (or
double) screw fitted into a groove or channel in the back of each side of the frame
and running lengthwise within it. This channel or groove may be fitted with
metal tube at lining to act as a correcting guide for the head of the screw which
would be made to fit the tube.
The frame is cut through in the centre of each of its sides and each side is held
together and supported in its expansion by a metal bed in which it slides being
held and guided by grooves and by the double screw.
The double screw is held in position by and revolves within a metal centre piece
which is fixed into the centre of the metal bed before referred to.
On the face of the centre piece (which projects slightly in front of the frame) is
fixed a thin, but ridged piece of metal forming the centre section, which may
resemble the frame in its moulding or be of any other suitable description and
of sufficient length to cover the opening raised in the side of the frame in its
expansion.
In order to obtain double expansion of the full inner length or sight of each side.
By expanding the frame as above described the extension is always equi distant
from the centre and the centre-section always retains its central position.
The action of expansion is brought about by simply pulling the opposite sides of
the frame in order to make it wider or higher as required.
Referring to the accompanying drawing Fig. 1. is a front view of one of my
frames before it is expanded. Fig. 2 is the same frame expanded to its full extent
both in height and width. (a) (a) are the centre sections the illustration shewing
one of thein at (b) removed the better to expose the working parts to view.
Fig. 3. is a side or edge of expanded frame and Fig. 4 is a view of part of the
back of the frame when closed. (c) is the reverse action or double screw which
travels in the groove (d) which being under the surface of the frame is shewn in
dotted line (e) is the metal bed (f) Fig. 5 shewing one of the set of grooves to help
to keep the sliding portions in position (g) is the metal centre piece fixed into the

in which the double screw revolves.
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
- Improvements in expanding picture frames substantially as herein set forth and
specified whereby I am enabled to obtain precise and graduated expansion up to
double the original interior demensions.
