PROVISIONAL SPECIFICATION.
An Improved Lens-carrying Picture Frame or Attachment for
Picture Frames.
I, DAVID ABRAHAM LOWTHIME, of 17, Lambs Conduit Street, London do hereby
declare the nature of my said invention for "AN IMPROVED LENS-CARRYING PICTURE
FRAME OR ATTACHMENT FOR PICTURE FRAMES to be as follows :-
"
My Invention is intended, more especially, for use in connection with photographs,
and may bé constructed as either a picture frame of which the lens-carrying apparatus
forms a part, or as an attachment for a picture frame in which the lens-carrying
apparatus is fitted with lugs or other means by which it may be attached to a frame.
I attach to the frame, about midway in its length, or to lugs, or the like to be so
attached to a frame, two horizontal pins, one on each side of it, so attached that they
can be turned on their longitudinal axes, and which are pierced, transversely, so as to
form eyes throngh which are made to slide the ends of a wire next described.
The wire to which the lens is attached, and by means of which its movements are
effected, is bent twice at right angles (the corners being preferably rounded) the
central portion being rather longer than the width of the frame, so that it may lie
just over the top of the frame and the two end portions pass down one on each side
of the frame to and through the eyes previously described.
On the central portion of such wire I mount a sliding piece with a binding screw
to clamp it, and thereto I attach, preferably in an ornamental sitting, a lens suitable
for use in looking at the picture. When not in use the lens thus rests over the top
of the frame in the centre and has an ornamental effect.
When about to be used the lens is drawn forwards and downwards in front of
the picture, the apparatus turning on, or with the pins first described, the lens is
then turned round on the wire so as to face the picture and slid along the wire to
bring it before the part of the picture to be examined where it may be clamped by
means of the binding-screw. The distance of the lens from the picture may also be
adjusted by sliding the wire through the eyes and clamping it in the desired position
by means of binding-screws provided for that purpose.

page_text: As the apparatus is intended to be of a decorative character it will be readily
understood that the various parts may be made of any ornamental shape which is
not inconsistent with their functions, and that the ends, corners and other parts may
be finished off with appropriate ornamentation.

An Improved Lens-carrying Picture Frame or Attachment for
Picture Frames.
I, DAVID ABRAHAM LOWTHIME, of 17, Lambs Conduit Street, London, do hereby
declare the nature of my said invention for "AN IMPROVED LENS-CARRYING PICTURE
FRAME OR ATTACHMENT FOR 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 sheet of drawings and to the
letters and figures marked thereon :-
:-
My invention is intended more especially for use in connection with photographs,
and may be constructed as either a picture frame of which the lens-carrying
apparatus forms a part, or as an attachment for a picture frame, in which the lens-
carrying apparatus is fitted with lugs or other means by which it may be attached to
a frame.
In the accompanying sheet of drawings Fig. 1 represents my said lens-carrying
picture frame or graphoscope in front elevation, the lens-carrying apparatus forming
part of the frame.
Fig. 2 is a side elevation of the same showing also in broken
lines the manner in which the lens may be brought forward for inspection of the
picture.
Fig. 3 is a detail section showing the construction and arrangement of the parts
by which the wire is attached to the frame and Fig. 4 is a similar section of the
apparatus as constructed as an attachment to a wooden frame.
In figs. 1, 2 and 3, A is the frame, that shown in the drawing being made of
metal and intended for the reception of a photograph or the like; b, b,. are pins
riveted to the side of the frame but so that they may be turned on their horizontal
axes, and which are pierced transversely with eyes through which the wire passes.
The wire C on which the lens D is mounted and by which its movements are effected
is bent twice at right angles (the corners being preferably rounded) and the central
portion c¹ being rather longer than the width of the frame so that it may lie just over
the top of the frame as shown in Fig. 1 and the two end portions pass down. one
on each side of the frame to and through the eyes in the pins b.

page_text: On the central portion c¹ of the wire C1 mount a sliding piece d with a binding-
screw, having a milled head f, and to the sliding-piece d I attach, preferably in an
ornamental setting, a lens D suitable for use in looking at the picture. When not in
use the lens rests over the top of the frame in the centre as shown in Fig. 1 and has
an ornamental effect.
The slide-piece d enables the lens to be moved transversely along the wire as is
indicated in broken lines in Fig. 1, and the portions c² of the wire may be slid through
the eyes so as to adjust the distance of the lens from the picture and may be clamped
by the binding screws g, g, I provide two stops h, h, to prevent the wire passing over
the back of the frame when not in use.
In Fig. 4 I have shown the way in which the lens-carrying apparatus may be made
as an attachment for a wooden frame and fixed thereto by screws or nails through the
plate or lugs k.
When about to be used the lens is drawn forwards and downwards in front of the
picture as shown by the broken lines in Fig. 2, the lens is then turned on the wire ()
so as to place it vertically or so as to face the picture and if desired may be slid along
on the wire so as to bring it in front of any part of the picture which it may be
desired specially to examine, and there clamped by turning the milled head f.
The distance of the lens from the picture may also be adjusted by sliding the wire
through the eyes in the pins b and clamping it by means of the binding screws g.
As the apparatus is intended to be of a decorative character it will be readily
understood that the various parts may be made of any ornamental shape which is
not inconsistent with their functions, and that the ends, corners and other parts may
be finished with appropriate ornamentation.
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:
Constructing Lens-carrying picture frames, and Lens-carrying attachments. for
picture frames, substantially as described and shown in the drawings and for the
purposes set forth.
