Year: 1873

page_text: LETTERS PATENT to Casimir Sipriot, of Milan, in the Kingdom of
Italy, Merchant, for the Invention of "AN IMPROVED APPARATUS FOR
BEMIDIFING PLACARDO PARTING BILLS AND OTHER ADVERTISEMENTS.
"
PROVISIONAL SPECIFICATION left by the said Casimir Sipriot at the
Office of the Commissioners of Patents, with his Petition, on the
10th February 1873.
I, CASIMIR SIPRIOT, of Milan, in the Kingdom of Italy, Merchant,
do hereby declare the nature of the said Invention for "AN IMPROVED
APPARATUS FOR EXHIBITING PLACARDS, POSTING BILLS, AND OTHER ADVERTISE-
MENTS,
," to be as follows, that is to say :-
My Invention consists in a peculiar construction of apparatus for
effecting a continuous or intermittent passage or travel of the placard,
or other advertisement before the eyes of persons passing by. This

page_text: apparatus consists of a box containing an endless sheet of paper or textile
material printed, or having designs thereon passing over rollers, and
kept distended by the weight of one of such rollers placed freely in one
of its folds. Motion is given by clockwork (or by other known means)
with or without an escapement, so as to obtain an intermittent motion.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Casimir Sipriot in the Great Seal Patent Office
on the 8th August 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CASIMIR
SIPRIOT, of Milan, in the Kingdom of Italy, Merchant, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of February, in the year
of our Lord One thousand eight hundred and seventy-three, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Casimir Sipriot, Her special licence
that I, the said Casimir Sipriot, my executors, administrators, and
assigns, or such others as I, the said Casimir Sipriot, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for AN IMPROVED
APPARATUS FOR EXHIBITING PLACARDS, POSTING BILLS, AND OTHER ADVERTISE-
MENTS," upon the condition (amongst others) that I, the said Casimir
Sipriot, my executors or administrators by an instrument in writing
under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed in
the Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Casimir Sipriot, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by

page_text: the following statement, reference being had to the Drawing hereto
annexed, and to the figures and letters marked thereon, that is to
say:
My. Invention consists in the arrangement and construction of an
apparatus by which placards, posting bills, and other advertisements
either printed, painted, or otherwise applied on a flexible material, such as
paper, cotton, or linen, and in one or several pieces like an endless band
or other like surface shall be caused to move before the eyes of the
public with a slow and continuous or intermittent motion. This
apparatus is constructed of a frame open on one side so as to exhibit a
part of the endless band which is made to move slowly at the same time
that it rises and falls, and seen on the side opposite that opening at M, N.
To give motion to the endless band I employ any suitable prime mover,
such as an air, steam, or water engine, or weights; but I employ by
preference a clock spring movement.
The annexed Drawing shews an apparatus so worked, in which
Figure 1 is a front elevation, and Figure 2 a section of my improved
apparatus; Figures 3 and 4 sections on a larger scale shewing the motive
mechanism.
In Figures 3 and 4, E is the barrel giving motion to a pinion D,
carrying with it the spur wheel C, driving the pinion B which turns the
wheel F, and carries with it an ordinary regulator.
The force of the spring and the combination of speeds are variable
according to the dimensions of the apparatus, and the speed to be given
to the surface to be displayed to the public eye.
Upon the axis of the pinion B I place a roller A passing right through
the apparatus, and giving motion to the endless band. This band passes
from top to bottom, and from bottom to top over a certain number of
rollers, the largest H Figure 2 being placed immediately behind the
central roller A, the smaller ones I being placed beyond. The number
of rollers may vary according to the size of the apparatus and the band
to be moved. To stretch the band I employ a roller K suspended freely
in a fold formed by that band; this roller is free to be raised or lowered
in the apparatus in order to regulate the tension of the band. The
exterior form of the apparatus may be varied; it may be placed internally
or externally, and be lighted up internally or externally; its motion

page_text: may be continuous or intermittent by placing a suitable escapement
the movement..
In witness whereof, I, the said Casimir Sipriot, have hereto set
my hand and seal, this Second day of August, in the year of
our Lord One thousand eight hundred and seventy-three..
CASIMIR SIPRIOT. (L.S.)`
