Patents, of 67, Strand, in the City of Westminster, Civil Engineer. " IMPROVE
MENTS IN MACHINERY FOR DISPLAYING ADVERTISEMENTS." A communication from
abroad by Alfred Anderson, of Paris, in the Republic of France.
The Invention consists in certain machinery for the display of advertisements in
such manner that they may be changed from time to time, or remain fixed for a
certain length of time as desired. The machinery consists of upper and lower
rollers both worked by a clock-mechanism, or the mechanism may be applied to
either roller; the rollers have stretched between them a continuous sheet of linen
or other fabric, on which is printed or otherwise delineated the advertisement.
Sometimes the linen is rendered transparent, and artificial light placed behind, and
so advertisements are displayed at night. In lieu of linen I sometimes use wooden
or metallic strips, or cylinders, or prisms, arranged blind or screen fashion, and on
these I delineate the advertisement.
The clock mechanism can be arranged to give, say, 5 minutes or other interval of
display through any convenient frame to each advertisement.

abroad by Alfred Anderson, of Paris, in the Republic of France.
This Invention consists in making advertisements more conspicuous by the
application of a clock-work or other mechanical device, which allows to change
such advertisements at intervals of 1, 2, 3, &c., minutes, as required. This Invention
may be applied to clocks where the advertisements appear in socle of the clock, or
in a separate case attached to such clocks, &c.; or it may be exhibited on sign-
boards and show-windows of shops, &c.; or in or outside of vehicles, such as railway
carriages, omnibuses, tram-cars, &c.; or on public and private street lamps as day
and night advertisements; finally, in waiting rooms of railways and steam boats,
or any other public place where their application may be desirable and allowed.
The Invention is performed by making appear such advertisements at an opening
of any suitable shape and size in a place where they are sure to be exposed to the
eyes of the public. The advertisements may be written or printed, &c., on strips of
paper, cloth, sheet-metal, etc., which are fastened, or wound upon cylinders or prisms
with any number of sides, or the advertisements may be written or made visible
on such cylinders or prisms directly. The motive device (f, i, a clock work) makes
these advertisements appear at the opening at certain intervals.
The interest of the public may be attracted more forcibly by intermixing views,
pictures, comic subjects, &c., with the advertisements. The advertisements may be
made transparent, and lit at night by any suitable means.
CLAIMS.
1. Causing advertisements to appear before an opening of whatever shape and
size at certain intervals by means of a mechanical device.
2. The application of a clock work for making the advertisements appear at
certain intervals.
3. The advertisements written or printed, &c., on strips of paper, or directly on
cylinders or prisms with any number of faces.
4. Making such advertisements transparent for being seen also by night, the
whole substantially as described.
In witness whereof, I, the said Herbert John Haddan, have hereunto set
my hand and seal, this Twenty third day of November, A.D. 1881.
