COMPLETE SPECIFICATION.
Improvements.in or connected with Apparatus for Advertising by
Means of Travelling Bands or Sheets.
We, ALBRECHT DREES, Engineer, and WILHELM GRASSES, Merchant, both of
Duisburg on the Rhine, near Cologne, 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 :-
Our improved apparatus differs from others chiefly by the fact, that it has several
openings or windows, through which the advertising band or sheet becomes visible
on both sides, so that if both sides of the said travelling sheet or band carry
advertisements applied in any convenient manner, all the advertisements become
visible without requiring the said sheet to be turned.
In the accompanying drawings Fig. 1 is an elevation, Fig. 2 a plan and Fig. 3 a
horizontal section of an apparatus embodying our invention.
The band or sheet is alternately wound on and off a pair of drunis 20¹, 20² set in
motion by mechanism, which may be of any convenient kind and does not form
part of the present invention. The peculiarity of our construction consists in a
special manner of guiding the travelling band or sheet.
--
We employ guide rollers ¹---, which guide the sheet rectilinearly along and
past the show windows or openings o¹. o, preferably covered with glass.
Between the drum w' and the drum 102 the travelling sheet is guided diagonally,
so that behind the show windows o³ and of it does not only move in a direction
opposite to its motion behind the windows o¹ and o², but it has the reverse side (of
the sheet) turned outward. The motion is so slow, that the advertisements may be
easily read or examined. We prefer to employ two pairs of show windows, as
illustrated by the drawings, in order that the same advertisement may appear
through two openings consecutively, but we may employ more or less than four
windows in the casing or frame work of the apparatus.
Instead of being rectangular in cross section, the apparatus or the casing
containing the same inay form any other convenient figure.
If an apparatus of this kind is mounted on a table at a restaurant, the frame or
casing of the same may also carry small articles in frequent request, such as match
boxes, date indicators, cigar cutters, or table bells.
The driving mechanism may impart to the travelling band either a continuous or
an.intermittent motion.
Instead of propelling and guiding the sheet on its whole width by means of
drums and guide rollers, it may be suspended at the top from a rope or chain which
is guided over suitable pulleys arranged like the guide rollers, so as to guide the
said sheet in the manner described.
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. Apparatus for the alternate exhibition of advertisements, comprising in its
construction a frame-work or casing provided with show windows or openings, a
moveable band or sheet carrying the advertisements or objects to be exhibited, and
a set of guide rollers 1 to 6, the said travelling sheet or band and the guide rollers
being arranged in such a manner, that one side of the said band becomes visible
through one or more of the said windows, and at the same time the other side
appears through the other window or windows, substantially as and for the purpose
described.
