"
of Kent, Mechanical Engineer, for the Invention of AN IMPROVED METHOD
OF AND APPARATUS FOR EXHIBITING ADVERTISEMENTS, SHOW CARDS, AND
THE LIKE."
Sealed the 11th November 1879, and dated the 19th May 1879.
PROVISIONAL SPECIFICATION left by the said Hermann Adolph Reinhold
at the Office of the Commissioners of Patents on the 19th May 1879.
HERMANN ADOLPH REINHOLD, of Woolwich, in the County of Kent, Mechanical
Engineer. "AN IMPROVED METHOD OF AND APPARATUS FOR EXHIBITING
ADVERTISEMENTS, SHOW CARDS, AND THE LIKE."
This Invention relates to an improved method of and apparatus for exhibiting
advertisements, show cards, and the like, whereby the advertisements are slowly
raised from a receptacle or case, and after having been fully exhibited are quickly.
caused to fall back into the said receptacle or case, another advertisement immediately
commencing to appear.
The improved apparatus is constructed of a series of gearing operated by a spring
similar to a clock movement, and placed in a suitable case or receptacle. On the
end or ends of the pivot or pivots of one or more of the wheels I fix a number of
cranked arms.
The top of the case of the apparatus is formed with a number
of slots, according to the number of advertisements, show cards, or the like. The
advertisements, show cards, or the like to be exhibited are printed, written, or
otherwise formed on tablets of suitable material, the lower parts of each of such tablets
being formed with an oblique slot or with a foot The tablets are dropped into the .
slots in the top of the case, and as the said cranked arms revolve the projecting
ends thereof will pass into the slot or press against the foot of the corresponding
tablet, and the tablet will be slowly raised outside the case. As soon as the said
tablet has been fully raised it will remain in this position for a short time and then
quickly and automatically drop back into the case, the next tablet immediately
rising, and so on for all the tablets.

the said Hermann Adolph Reinhold in the Great Seal Patent Office on the 18th
November 1879.
HERMANN ADOLPH REINHOLD, of Woolwich, in the County of Kent, Mechanical
Engineer. "AN IMPROVED METHOD OF AND APPARATUS FOR EXHIBITING
ADVERTISEMENTS, SHOW-CARDS, AND THE LIKE."
This Invention relates to an improved method of and apparatus for exhibiting
advertisements, show cards, and the like, whereby the advertisements are slowly
raised from a receptacle or case, and after having been fully exhibited are quickly
caused to fall back into the said receptacle or case, another advertisement immediately
commencing to appear.
The improved apparatus is constructed of a series of gearing operated by a spring
similar to a clock movement, and placed in a suitable case or receptacle. On the
end or ends of the pivot or pivots of one or more of the wheels I fix a number of.
cranked arms. The top of the case of the apparatus is formed with a number of
slots according to the number of advertisements, show-cards, or the like. The
advertisements, show-cards, or the like to be exhibited are printed, written, or
otherwise formed on tablets of suitable material, the lower parts of each of such
tablets being formed with an oblique slot or with a foot. The tablets are dropped
into the slots in the top of the case on to a pivot or fulcrum therein, and as the said
cranked arms revolve the projecting ends thereof will pass into the slot or press
against the foot of the corresponding tablet, and the tablet will be slowly raised
outside the case. As soon as the said tablet has been fully raised it will remain in
this position for a short time and then quickly and automatically drop back into
the case, the next tablet immediately rising, and so on for all the tablets.
But to make my Invention better understood I will proceed to describe the same
by reference to the accompanying Drawing, in which Figure 1 is a front elevation
of my improved apparatus (the front of the case being removed); Figure 2 is a plan
of the apparatus, and Figure 3 is a transverse vertical section of the same; Figure 4
is a detached view of one of the advertisement tablets.
A is the case or receptacle in which I fix the clock movement B. On the end of
the pivot of the third wheel C (or it may be on one of the other wheels) I fix a
number (by preference three) of radial cranked arins D. In the top of the case of
the apparatus is hinged a block E formed with slots F corresponding with the
number of advertisements to be exhibited. G is a pin forming a fulcrum on which
the advertisements pivot as hereinafter described.
The advertisements, show-cards, or the like, to be exhibited are printed, written,
or otherwise formed on tablets H of suitable material, the lower part of each of
such tablets H being formed with an oblique slot I forming an eccentric. The
tablets H are also cut away at J so that when they are placed in the slots F the
part will rest or bear on the fulcrum G. L is an adjustable sheet metal rest
screwed on the block on which the tablets rest when in their horizontal position.
By this construction and arrangement it will be understood that if the tablets H
be placed in the slots F and the clock movement be set in motion the radial arms D
will be rotated in the direction of the arrow, and as the crank d of each arm comes
against the end of the oblique slot I of its corresponding tablet the crank will press
against the slot I and thereby gradually raise the tablet which turns on the
fulcrum G into a vertical position, as shewn in Figures 1 and 3 of the Drawing,
and the tablet remains in that position until the crank in its rotary movement
passes out of the slot I when the tablet falls into its horizontal position, and the
next crank will commence to raise the next tablet, and so on for all the tablets in
rotation.
It will be understood that instead of the tablets being cut away at J they may
be simply perforated at j, in which case the pin or fulcrum G would have to be

page_text: passed through the said holes, but I prefer the form shewn in the Drawing, as this
allows of the tablets being simply dropped into the slots whereupon they take
their position automatically and may be taken out and changed at pleasure.
Instead of a clock movement any other suitable motive power may be
employed.
Having thus described my Invention and the manner of performing the same, I
wish it to be understood that I do not confine myself to the precise details herein
laid down and shewn in the Drawing, as the same may be varied without departing
from the peculiar character of the Invention; but what I do claim is,-
Firstly. The construction and employment of the improved apparatus for
exhibiting advertisements, show-cards, and the like, arranged and operating
substantially as herein before described, and represented in the accompanying
Drawings.
Secondly. In an apparatus for exhibiting advertisements, show-cards, and the
like, I claim the combination with a number of slotted tablets moving on a fulcrum
in a slotted guide of a corresponding number of cranked arms fixed on any suitable
shaft having a rotary motion, whereby the said tablets are automatically caused to
rise and fall in rotation, as and for the purpose hereinbefore described.
In witness whereof, I, the said Hermann Adolph Reinhold, have hereto set
my hand and seal, this Seventeenth day of November, in the year of our
Lord One thousand eight hundred and seventy nine.
