Improvements in Apparatus for Exhibiting Photographs, Pictures,
Advertisements, and the like.
I, CHARLES FERDINAND VEIT of Bartlett's Buildings in the City of London,
Commission Agent, do hereby declare the nature of this invention to be as
follows:-
This invention relates to that class of apparatus for exhibiting photographs,
pictures, advertisements, pictorial or otherwise, and the like, in which a number of
frames are so mounted and operated (by means of clockwork, or in any other
convenient manner, automatically or otherwise) that they will be caused to open
out like a book, in order to display the pictures etc., and the invention consists in
certain improvements in construction, and otherwise, whereby this class of apparatus
is rendered more efficient for the purpose desired.
In carrying out these improvements, I take two discs, which I mount at opposite
ends of a tube, of the length required, and round the discs, near the edges, I form
a series of holes or slots, to receive rods for supporting the frames containing the
pictures, photographs, etc.
The top ends of these rods I prefer to flatten out and twist to a spiral form, and
these spiral ends fit into slots in the top plate. The lower ends of the rods, below
the bottom disc, are bent outwards. These bent ends strike against a fixed stop,
which causes the rods to rise in the sockets, and, on passing the obstruction, under
the influence of a pawl and ratchet movement, or any other convenient operating
contrivance, the spiral ends of the rods will, under the influence of the weight of
the frames they carry, cause the rods to turn in their sockets, and thus display the
contents of the frames.
These rods may also be provided with adjustable sockets, into which may take
hooks formed on the frames, so that the frames may be removed or replaced with
facility. The rods may, however, be integral portions of the frame.
The frame support thus arranged will be placed on a spindle connected with
clockwork, or simply mounted on a rod carried by a suitable pedestal.
When clockwork is used, the frame support may be keyed to the spindle in
any convenient manner, so that it may be rotated, notwithstanding fixed cam
obstructions, and a cap piece and knob will be fitted to the spindle, to give a
finish...
To work the frame support by hand, I prefer to employ a pawl and ratchet
movement, but I may also provide a toothed wheel mounted on an axle carried by
the pedestal, and which is turned by a knob or handle on one end. The wheel is
geared to a pinion on a disc which is mounted on a stud pin secured to the pedestal
below the frames. The disc may be formed with two or more notches, one side of
which may be made to project slightly to catch under the bottom rail of the frame,
as the disc rotates, and help the rail pass the stop or obstruction, the support being,
at the same time, driven, by suitable gearing, from the axle of the toothed wheel,
or in any other convenient manner.
This operating mechanism may also act on pins projecting from the frame rods,
and may be placed inside or outside the pillar or standard. Or, in place of the
disc, a star wheel may be employed, and suitably driven, so that the arms may act
on the frames, or on projections from the frames.
The full part of the disc, when used, will also project above the bottom rail of
the frames, and will serve to hold the frames open while inspection of their contents
is taking place.
The frames may be of metal, with clips to hold the pictures, or in any other

page_text: convenient manner, but for large apparatus I prefer to make the frames of cane,
with suitable stays, and covered with linen, muslin, or other suitable light material,
to which the pictures, photos, etc., may be pasted or otherwise attached.
In order to provide against the disorganising of the clockwork, when the frame
supports are turned backwards, a thing which is very likely to happen, I attach
the spindle on which the support is mounted to the driving spindle of the clockwork,
in such a manner, that the support spindle may turn independently of the driving
spindle.
The apparatus may be placed in a lantern or glass case, and may be illuminated
by external lamps, like shop lamps, or by electric light, the electricity being also
used to drive a small motor to work the apparatus.
Means may also be provided to ensure the verticality of the spindle, so that the
apparatus will work when standing on an uneven surface, and such means may consist
of a convex collar on the clockwork containing a box working in a concave band
capable of being tightened up when the proper position is attained. The box may
be provided with a counterweight which may also be used as a handle for a key to
wind up the clockwork.

Improvements in Apparatus for Exhibiting Photographs, Pictures,
Advertisements, and the like.
I, CHARLES FERDINAND VEIT of Bartletts Buildings in the City of London,
Commission Agent, 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 :-
The object of this invention is to secure a simple and durable device for the
inspection of various articles, such as photographs, pictures, advertisements,
patterns and samples of goods and the like and the invention consists of a stand or
holder so constructed that by pressing a knob, or by clockwork or other device, a
number of vertical leaves or frames are caused to revolve and thereby their surfaces
on which are the pictures or objects to be seen are successively presented to view,
like the pages of an open album, without it being necessary to retain the said leaves
or frames by hand. This is effected by means of a check-piece or stop which
detains the frames on one side temporarily, while as they one by one glide past the
inner face of the check piece or stop, screw threads in the frames raise them a
certain distance and when freed by having passed the check piece or stop the
weight of the frames causes the latter to descend or drop from their raised position.
I will now describe my invention with reference to the accompanying drawing in
which
Fig. 1. is an elevation of the device sectioned along x .
Fig. 2. is a section along y y Fig. 1.
Fig. 3. is a section along z. z. Fig. 1.
Fig. 4. is a section along ¹¹ Fig. 1.
.
The base a of the device is provided with a rod or support 6 which as it is not
required to turn can be fixed or firmly and durably secured to the base. A sleeve h
can rotate about the rod said sleeve being rested or supported on a suitable brace
or support v. To the sleeve his secured a ratchet wheel t engaged by a suitable
pawl or knob s connected by a pin and slot connection to the brace v and provided
with a retracting spring. As the knob or actuating levers is reciprocated a step
by step rotation is given to the ratchet wheel t and sleeve h. The spring pressed
detent to prevents retrograde rotation of the ratchet wheel. The upper end of
stem or rod b is screw threaded and a suitably tapped knob i is screwed thereto.

page_text: This knob presses a sleeve h¹ against sleeve h so as to hold the latter in place.
The sleeve h¹ may be in one piece with knob i or formed as a separate piece.
To the sleeve h are fixed or secured discs df so as to rotate with the sleeve.
The lower disc d has holes in which rotate the rods or pintles j. The upper disc f
has holes tapped or suitably formed for the engagement of screw threads k. The
screw threads
may be formed on the rods ; as in the case of the rod j at the right
looking at Fig. 1. or as seen at the left in said figure the rod j and screw thread k
may be separate pieces.
The frame for carrying the pictures or objects to be displayed can be secured
to the rod j and screw thread kas seen in the left in Fig. 1. or as seen in the right
in said figure the rod j may have arms or eyes A engaged by hooks or fastenings B
on the frame
q for holding the latter on the rod j.
Secured to base a is a check piece or stop l. Each rod or pintlej has a finger m
advantageously formed integral therewith by being bent from the wire or rod
forming the pintle j. As the sleeve and discs dfare rotated the fingers m are
successively brought against the check piece l so that as the outer end of finger or
finger piece m glides past the inner face of check piece 7. the corresponding rod j.
and frame q are somewhat held back or rotated backward toward the succeeding
frame. This backward rotation of rod j fully exposes the front face of the frame g.
and also causes the screw thread k to act so as to raise or screw up the rod j and
frame g a certain distance and when the finger m is freed by having passed check
piece the weight of the frame 9 causes the latter to descend or drop from its
raised position. This descent or drop of the frame q causes the screw thread k to
rotate the frame 9 forward toward the preceding frame thus causing the rear face
of the preceding frame to be covered and the rear face of the frame which has just
swung clear of the check piece to become exposed.
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. The combination with a fixed or non rotary stem or support of rotary frames
about said support, and a check piece or stop for holding each frame temporarily in
an exposing position as it passes the stop, substantially as herein described and set
forth.
2. The combination with a fixed or non-rotary stem or support of rotary frames
about said support, and a check-piece or stop, said frames having finger pieces
adapted to come into engagement with the stop for holding each frame temporarily
in an exposing position substantially as herein described and set forth.
3. The combination with a stem or support of rotary frames having axes and
screw threads arranged about the support, and a check piece or stop adapted to
swing or hold the-frame so as to raise the latter by the action of its screw thread,
said frame when it has cleared the stop being caused to sink by its weight so as to
rotate toward the preceding frame under the action of the screw thread substantially
as herein described and set forth.
4. The combination with a fixed or non-rotary stem or support of rotary frames
about said support, a ratchet wheel and pawl for rotating the frames, and a check
piece or stop for holding each frame temporarily in an exposing position sub-
stantially as herein described and set forth.
5. The combination with a stem or support of a rotary sleeve about said stem,
discs fixed to said sleeve, frames jointed to said discs, means for rotating the sleeve
and a check piece or stop for temporarily holding each frame in an exposing
position substantially as herein described and set forth.
