COMPLETE SPECIFICATION.
Improvements in or relating to Apparatus for Advertising, Exhibition
and similar Purposes.
We, THEODOR LÜTZENRATH, Merchant, of Bahnhofstrasse, No. 29, Erfurt, and
CARL ANDING, Merchant, of Villa Anding Grunstedterstrasse, No. 22, Weimar,
both in the Empire of Germany, 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 relates to apparatus for advertising exhibition and similar pur-
poses such as forms the subject of British Patent No. 7486 of 1898.
By means of these improvements it is possible to exhibit a number of placards
or devices of any desired size.
In the subjoined drawing, Fig. 1 is a side view and Fig. 2 a front view of the
improved apparatus.
As will be seen from these figures the placard P or devices to be exhibited,
which should preferably be attached to metal sheets or strips hang by means of
hooks, 100, which are soldered, c
, or otherwise fastened to the sheets, on bars 101 of
convenient length for the devices to be exhibited which bars form the pivots for
the links of the two chains. 102.
These chains 102 are worked over two pairs of wheels 103 and 104 which are
placed at a convenient distance apart and of which the upper pair 103 is consider-
ably smaller than the lower pair 104. The large wheels are driven by an inter-
mittently acting device pivotted on the shaft 105 in bearings of the standard 1.
This shaft 105 is provided preferably at each end with a lever 106 carrying
spring latches or pawls 107 which are made to engage with pins 108 on the chain
wheels 104.
To the lower end of the levers 106 are connected intermediate bars 109 coupled
to levers 111 which are fulcrummed at 110 on the standard 1.
These levers 111 are provided with pins or rollers 112 which are acted upon
by cams or curved discs 113 fixed to the shaft 3 by which they are alternately
raised and lowered at the right moment, thereby securing a proper working of the
levers and intermittent rotation of the wheel by which means the placards or
devices brought into position to be seized lifted up and again returned to their
places by the show figures.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
1. In an advertising, exhibition or similar device in which cards advertisements
or other devices are intermittently raised, exhibited and returned to their place the
arrangement of two pairs of chain-wheels at a convenient distance apart provided
with two chains operated by them the pivots of the links of which chains are
formed by the ends of cross bars on which the devices to be exhibited are hung

page_text: one pair of the wheels being intermittently rotated by a pawl on a pivotted lever
actuated 'from a cam on a shaft 3 substantially as described.
2. The combination and arrangement of parts constituting the complete device
for use in advertising or exhibiting cards advertisements or the like substantially
as described or illustrated in the accompanying drawings.
Dated this 9th day of January 1899.
