Mechanical Engineer, do hereby declare the nature of this invention to be as

of a spring plate or of a cam which retains the leaves on the one side while on
the other side they arrange themselves as they are released and automatically by
the action of an inclined plane or escapement.
In carrying out the invention the central vertical rod is secured to a base or
support by means of a nut or otherwise. On the rod are fitted an upper and a
lower disc having each as many lugs as there are to be leaves or frames for the
pictures. The rod has a flat side and the central hole of the discs is formed. to
correspond so that they will turn with the rod. The discs are kept at the proper
distance apart by separating tubes and the rod has a knob or similar device at
top by which it can be rotated. The lugs of the discs have holes to receive
pintles on the leaves or frames and the lugs of the lower disc are inclined so as
to form a sort of escapement in order that when a spring plate fixed to the base
of the stand allows a leaf to pass, this leaf will make a half turn thereby bringing
its second face into view and at the same time expose the first face of the next
leaf; this movement is ensured by means of a cam on each bottom pintle moving
on the inclined plane of the corresponding lug. Each leaf can have at its point
of contact with the spring plate a metal or other piece to protect it from wear.
The leaves are retained on the stand by a cap which is itself fixed by distance
pieces and the knob. In order to change the leaves it is only necessary to remove
the knob and the cap.
The stand can be made to hold any desired number of leaves or frames and
it may be arranged for two superposed sets or tiers which can be turned either
together or separately and by means of a clock movement or otherwise.
In a modification of the apparatus the two discs are flat and the escapement
before described is obtained by inclining the axes of the leaves relatively to that
of the apparatus. The spring plate above described for retaining the leaves can
be replaced by a cam fixed in the same manner and at the same place. When
the knob and rod are turned this cam allows the leaves to pass one by one and
by the simple inclination of their axes they each make a half turn so as to
exhibit their second face and expose the first face of the next leaf.
When a clock movement is employed to turn the apparatus, I preferably fit
to the barrel arbor a pin which engages with the teeth of a ratchet pinion on
the axis or vertical rod of the apparatus so that the knob can be turned
independently of the clock movement without putting this out of gear.
The frames or leaves can be made of wire and have small clips to retain the
pictures. When they are to be used on a stand having the inclined plane escape-
ment hereinbefore described the bottom wire should be soldered to one side of a
vertical rod forming the frame side so as to constitute a cam; and when it is
intended to provide for turning the leaves in either direction the wire should be
forked and soldered to both sides of the said vertical rod.

page_text: If the frames or leaves are made double that is to say, so as to hold two tiers
of pictures, the two parts may be of the same dimensions to hold pictures of the
same size, or of different dimensions to hold pictures of different sizes.

COMPLETE SPECIFICATION.
A Stand or Holder for Exhibiting Pictures and the like.
I, VICTORIEN LOUIS MARIE RENARD, of 1 Boulevard St. Denis, Paris, France,
Mechanical Engineer, 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:--
This invention consists of a stand or holder for exhibiting and displaying pictures,
photographs, announcements and other similar objects. This stand.is so constructed
that by turning a central vertical rod, by means of a knob or other device, or by
clockwork, 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 projecting
check-plate and cam which detain the leaves on one side temporarily, while as they
one by one surmount the obstruction, and pass over to the other side, they arrange
themselves automatically by the action of an inclined plane or escapement.
I will now describe my invention with reference to the accompanying drawings in
which
Fig. 1 shews an elevation of my improved holder, and
Fig. 2 a vertical section with the pictures frame and base omitted.
Fig. 3 shews an enlarged plan of the upper disc d of the Fig. 2.
Fig. 4 shews an elevation of one form of stand adapted for clock-work action and
with the leaves in position and the check-plate s, holding back the leaves on the
right hand.
Fig. 5 shows the frame g, of the leaf detached.
Z, is a view of the bottom bar 1, of the frame shewing the small cam k, at the
end, and also the peculiar position of the bar 1, to the cam k.
Fig. 6 shews another mode of forming the bar 1, when it is intended to turn it in
either direction.
Figs. 7 and 8 shew double frames one over the other.
It will be scen in Figs. 1 and 2 that the central vertical rod b, is secured to a
suitable base or support such as a, by means of a screw and nut e, or otherwise.
On this rod b, are fitted the upper and lower discs d, and, which are perforated
with holes to receive pins as shewn in Fig. 3, which pins are attached to the
leaves or frames g, in which the pictures are to be placed.
The leaves are designed to exhibit pictures or objects on both sides, and are fitted
with clips j to sustain them.
The discs d, and f, are so attached to the central rod b, as to turn with it, and at
The holes in the
the top of the rod b, is the knob i, by which it can be rotated.
lower disc are slightly inclined, as shewn in Fig. 1 so that when a leaf passes the
check-plate s, the leaf will make a half turn so as to bring its second face into view,
and at the same time expose the first face of the next leaf. The check-plates, is so
fixed that it does not rotate with the rod b.
Separating tubes around the rod b, keep the parts at their proper distance from
each other. When preferred and especially for large sizes of my holder, in place
of the cam k, a roller can be used upon the check plate, and also beneath the frame
or leaf to ensure the leaf revolving freely when turned. Each leaf can be furnished
with a bearing part p, to sustain the friction of the checkplates.

page_text: In place of the checkplate s, a vertical spring q, can be used as shewn in
Fig. 1.
The leaves are retained on the stand by a cap o, over the upper disc. This cap
is held in place by the knob i.
In order to change or remove the leaves, it is only necessary to remove the knob
and the cap.
In another arrangement represented in Fig. 4, the discs d, and f, which support
the frames g, are flat and the swinging action of the frames when passing the check-
plate, is caused by varying the vertical inclination of the frames from the perpen-
dicular line of the centre bar.
The stand can be made to hold any desired number of leaves or frames, and it
may be arranged for two or more superposed sets of leaves in tiers as shewn in
Figs. 7 and 8, which can be turned either together or separately, and by means of
a clock movement or otherwise.
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 method of automatically displaying simultaneously the sides of two leaves
of revolving vertical frames, as herein described and set forth.
2. In a revolving vertical stand or holder, the combination and construction of
parts, of any preferred dimension or shape, as herein described and set forth.
