(5) The various elements in which friction is called into play in order to produce
the semi-planetary motion about to be described.
(1) The framework is rectangular and composed of any suitable metal or
equivalent. In the middle of two parallel sides is pivoted (2) a revolving axis
centrally piercing and firmly attached to one or more (3) disks. In this description
I assume two disks both perpendicular to the axis. The disks are pierced near
their circumference by corresponding circular holes and in each pair of corresponding
holes is inserted (4) a semi-rotating frame made of wire or other. equivalent; the
ends of this wire project through the disks and one end or both ends of each wire
bears a milled head or equivalent. The form of the frame varies with the
necessities of the case. (5) Above or below in a plane perpendicular to that of
the framework is a piece of metal.in the form of an [firmly fixed and bearing on
each parallel side a cushion of gutta percha or equivalent, which cushion servés to
give to the milled heads a motion of semi-rotation due to the fact that they are
subject to a motion of translation arising from the. rotation of the axis. Of these
cushions the curvature of the one intersects the orbit of the milled heads interiorly,
the curvature of the other intersects it exteriorly. The cushions can be replaced
by revolving rollers moved by the axis. The rotation of the axis can also be
alternative. The axis is moved by clockwork or equivalent force. The wires
forming the frames can pass through the centre of and project beyond the milled
heads or equivalents.
I now proceed to describe the turn-cards with horizontal axis: Perpendicular
supports bear an axis and two or more disks pierced with corresponding pairs of
holes into which are introduced frames semi-rotated by milled heads rubbing against
cushions, all as before described except that one cushion may be omitted, the force
of gravity sufficing to semi-rotate the frame backwards.
For the milled heads in both forms of turn-cards can be substituted levers formed
by bending the ends of the wires composing the frames at right angles to the line
connecting two corresponding holes. These levers coming into contact with above-
mentioned cushions or pins or other equivalent, the frames are semi-rotated.
In practice I insert photographs in clips attached to the wire connecting two
corresponding holes; the motion of the axis is due to a powerful spring or to a
heavy weight and is regulated by a governor or fan as employed in musical boxes.
.

page_text: I cap also cause the disks, especially when large, to be revolved independently
yet synchronously on a non-revolving axis. The disks can also be rotated
synchronously by means of independent springs or weights along with a common
fan. By each of the above described arrangements I give to a series of frames a
circular motion of translation either continuous or alternative, simultaneously giving
them a motion of semi-rotation counter-clock-wise succeeded by a motion of semi-
rotation clock-wise, or vice versa. Each complete revolution of the disks gives rise
first to a semi-rotation in one sense and then to a semi-rotation in the other sense.
By semi-rotation". I mean a rotation through 180 degrees or thereabouts.

Improvements in Apparatus for Displaying Photographs, Pictures,
Advertisements, Samples, and the like.
I FRANCIS EDWARD SUDDARD, Ars an der Mosel, Lothringen, Germany,
Professor, 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 :-
I give I. an unfigured description II. a figured description of invention.
:
I. The object of my turncards is to present to view immediately the one after
the other each of the sides of a card or frame forming a series; thus photographs,
pictures, advertisements, samples and the like can be displayed somewhat after the
manner of the well known revolving machines. I employ two main forms of my
apparatus:
(1) The turncards with vertical axis,
(2) The turncards with horizontal axis.
The turncards with vertical axis embraces five important parts:
(1) The framework.
(2) The axis..
(3) The disks.
(4) The frames or card-holders.
.3
(5) The various elements in which friction is called into play in order to produce
the semiplanetary motion about to be described.
(1) The framework is rectangular and composed of any suitable metal. In the
middle of two parallel sides is pivotted (2) a revolving axis attached to one or
more disks firmly fastened to it. In this description I assume there are two disks
both perpendicular to the axis. The disks are pierced near their circumference by
corresponding circular holes and in each pair of corresponding holes is inserted
(4) a semi-rotating frame made of wire or other equivalent; the ends of this wire
project through the disks and one or each end bears a milled head or equivalent.
The form of the frame is varied according to the necessities of the case. Above
or below in a plane perpendicular to that of the framework is a piece of
metal in the form of an firmly fixed and bearing attached to each parallel side a
cushion of gutta percha or equivalent, which cushion serves to give to the milled
heads a motion of semi-rotation due to the fact that they (the milled heads) are
subject to a motion of translation due to the rotation of the axis (2).
Of these cushions the curvature of the one intersects the orbit of the milled heads
interiorly, the curvature of the other intersects it exteriorly. The cushions can be
replaced by revolving rollers moved by the axis. The rotation of the axis is due
to clockwork moved by a spring or weight. I proceed now to describe the
turncards with horizontal axis. The wires forming frames can pass through the
centre of and project beyond the milled heads.
Vertical supports bear an axis and two or more disks pierced with holes into

page_text: which frames are introduced rotated by rubbing against cushions, all as above-
described except that one cushion may be omitted, the force of gravity sufficing to
reverse the position of the frames. For the milled heads in both forms of my
turncards can be substituted levers formed by bending the ends of the wires
composing the frames at right angles to the line connecting two corresponding holes.
These levers coming into contact with the above-mentioned cushions. or; with
pins perpendicular to disks or equivalents to cushions or pins, the frames are
.semi-rotated.
...In practice I insert photographs in clips attached to the wire connecting two
corresponding holes; the motion of the main axis is due to a powerful spring
or weight and is regulated by a train of wheels actuating governor or fan, as.
employed in musical boxes and turnspits.
:
I can also cause the disks, especially when large, to be revolved independently
yet synchronously on a non-revolving axis. The disks can also be rotated.
synchronously by means of independent springs or weights.
By semi-rotation I mean a rotation through 180 degrees or thereabouts.
Thus far the unfigured description; now comes the figured description.
i
11. First read my unfigured description down to "exteriorly" and turn to the-
drawings annexed to the present Complete Specification.
Fig. 1, Sheet 1 represents in isometrical projection a turncards with vertical
axis.
Fig. 2, Sheet 2 represents in isometrical projection a turncards with horizontal
axis.
Fig. 3, Sheet 3 represents in orthographic projection on an enlarged scale the:
frictional parts of the vertical turncards.
Figures 4 & 5, Sheet 3 represent in orthographic projection on an enlarged scale
the frictional parts of the horizontal turncards.
The drawings show but 4 or frames, although in practice 1 put some 16 into a
disk of the size of Fig. 4, Sheet 3. In Fig. 2, Sheet 2 I show fand m to the left,
although I usually put them to the right.
:
To each wire attach clips C C as shown attached to one only.
Fig. 1 Sheet 1 shows a turncards with vertical axis A preferably hollow rotated
by a motor acting, say, at A¹. The motor may be a powerful turnspit with con--
tinuous motion. EEEE is the metallic framework preferably screwed down to.
the motor. The disks D are soldered, or otherwise attached perpendicularly to A.
HH are circular holes bored near the circumference of the disks. Into each pair
of corresponding holes is inserted a round wire W one number less than the calibre
of H, so that W can rotate freely. One end or each end (I show but one in
Fig. 1) of W pierces centrally and is soldered to a milled head or small toothed
wheel M which on each rotation of A rubs against F & F (Fig. 3, Sheet 3) which
are either toothed or made of india rubber or like yielding substance. F being.
fastened between M¹ & A, naturally M' rotates in direction of arrow, and the
arc F being of same length as half the circumference of M' or thereabouts, M' is.
rotated through 180 degrees. When M' reaches F', it is rotated back through the
same 180 degrees, thus exposing in turn each side of a card held by C C. The
same holds good of M³, M, etc. The clips should be small and light. The milled.
heads should preferably rest on the upper surface of D. Let A rotate glowly.
Articles held by C should preferably be of small weight.
"The wires forming
frames can pass through the centre of and project beyond the milled heads."
the wire is kept in its place by the milled head.

Read in my unfigured description from "I proceed now to describe the turncards.
with horizontal axis." Turn to Fig. 3, Sheet 3. Imagine FA T to be vertical and F'
to be removed, & A to be horizontal. Then M' on coming into contact with F rotates.
through 180 degrees and on passing through the positions of M², M³, M is gradually
rotated back again under the influence of gravity; just before reaching M', it is.
showing the face and on passing M', it shows the back. For the milled heads in
the horizontal turncards can be substituted a pin & levers m, see Fig. 2, Sheet 2.

page_text: and Figures 4 & 5, Sheet 3. Bend levers to form an angle of 90 degrees with the
wire and an angle of from ninety to 140 degrees with the tongue of the clip, the
opening of the clip being turned away from the lever. See dotted projection of
clip Fig. 4, Sheet 3. Insert fin hole .. Then the lever m trips against f & takes
the position of m*. Thus face is first visible, then obverse. In Fig. 2 note
that S is a standard for the axis A, and R is motor.
For milled heads in the vertical turncards levers m and pin f can be substituted,
if an alternating motion of rotation be given to A. Suppose that the turncards is
just beginning to act. If Fig. 4, Sheet 3 represent the lower disk, it is obvious
that will turn m while the disk rotates counter-clock-wise.. Fig. 5, Sheet 4
represents upper disk in a position & at a moment corresponding to Fig. 4, Sheet 3.
Then clearly w³, w³, etc. will trip against inserted in Q, when A rotates clock-
wise, for they will have assumed the position of the dotted levers. Fig. 6, Sheet 4
shows a possible, though not very useful mode of turning the milled heads. The
spur-wheel G keyed on to A engages with N supported by a bracket (not shown)
unconnected with either A or D. M is a milled head, which will be rapidly rotated
counter-clock-wise. For possible positions of motor or motors R refer to my
unfigured description and present drawings.
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. In respect of an apparatus destined to display automatically photographs and
the like the employment of milled heads or equivalent to turn the photographs &
that in combination with cushions made of yielding material or the equivalent of
such cushions against which the milled heads rub, when they revolve, in such a
manner that they (the milled heads) are turned first in one direction and then in
the other, all substantially as described and illustrated.
2. In respect of an apparatus destined to display automatically photographs and
the like the employment of little levers at the ends of the wires to which
the photographs are attached and that in combination with pins with which the
little levers come into contact whereby the alternate turning of the photographs
and the like is effected, all substantially as described and illustrated.
