PROVISIONAL SPECIFICATION.
An Improved Mechanical Advertising Apparatus.
JOHN HANDSLEY DALES of 45 Lofthouse Place, Leeds in the County of York,
Civil Engineer and HERBERT GEORGE UNSWORTH of Grove Villas Osmaston
Road, Derby in the County of Derby Mechanical Engineer do hereby declare the
nature of this invention to be as follows:-
Our invention consists of an apparatus, actuated by clockwork or other motive
power, for the purpose of exhibiting successively on suitable strips or cards, tablets
or bands, a series of prices, notices, names or other matter which it is desired to
place before the public, and which are to be exposed in shop windows or other
suitable situations.

In carrying out our invention we provide a set of tablets, strung together by their
edges or otherwise somewhat after the manner of pattern cards as used in a Jaquard
loom so as to form a band endless or otherwise. The advertisements are displayed
on the tablets. The band or bands of tablets, pass over a roller or rollers, placed
preferably in a horizontal position between suitable supports in such a manner that
the action of the motive power will successively exhibit at a suitable aperture' one
or any number of the said tablets, as they rise or fall either with a continuous or
intermittent motion, and the tablets are lifted or deposited, off or onto a pile of
them, which is formed by the action of the apparatus, also after the manner of the
Jaquard loom.
The main object of the invention is to exhibit a comparatively large number of
advertisements in any given space.
The motive power may be contained either in the rollers or in a kind of box
plinth, and imparts the necessary motion to the apparatus by spindles and wheel
gear, chains or bands.
The action of the tablets may be either continuously progressive or backwards &
forwards.

COMPLETE SPECIFICATION.
An Improved Mechanical Advertising Apparatus.
JOHN HANDSLEY DALES of Number 45 Lofthouse Place, Leeds in the County
of York, Civil Engineer and HERBERT GEORGE UNSWORTH of Grove Villas,
Osmaston Road Derby in the County of Derby, Mechanical Engineer, 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 invention consists of an improved method and apparatus for exhibiting at an
aperture in a suitable case a series of articles printed or other advertising matter or
samples of goods in which the exhibition cards, strips, cases or the like are auto-
matically moved and folded into a suitable receptacle and out of the same for the
purposes of the apparatus, by means of main springs, hydraulic power, movement of
doors or any suitable means. The folding motion is of a similar nature to that of
the pattern card motion of a Jaquard loom.
The motion of the advertisements may be made continuous, but is by preference

made intermittent as being more striking to. the public eye when seen in shop
windows in which it is chiefly intended to employ the invention.
In carrying out the invention we employ driving power by preference consisting
of a main spring and train of wheels, which in the accompanying sheet of drawings
is shewn to be divided into two sections; one for moving the exhibits and the other
for releasing the first from its stop action, one section of the train being driven from
the spring barrel and the other from the spring spindle.
In Figures 1 and 2. the spring barrel (a) is shewn geared to the roller (6) by the
train of wheels (a' a'a' a¹) and a one toothed snail (a) is fixed on the roller spindle.
The spring spindle: (c), which obviously revolves in an opposite direction to the
spring barrel, is geared by a train of wheels (c¹ c¹³ c¹) to a let off wheel (c) which
is made with an odd number of teeth. The spring spindle train is controlled by-a
fly motion at (d) or by an ordinary clock escapement geared to any convenient part
of the train (ccc c¹). The spring barrel. train is stopped on the single toothed
snail (a) in four or any desired number of places, by pawls (e. a. e. e). The pawl
teeth are made to engage the tooth of the snail (a) and also the let off wheel at the
same time, in such a manner that the let off wheel teeth which back against the
pawl teeth, can lift one pawl at a time out of gear with the snail tooth and so allow
the snail tooth to move to the next pawl and so on continuously, thus turning the
roller (6) and moving the exhibits which are carried round by its motion.
An enlarged view of the let off motion is shewn by Figures 4. and 5, Fig. 6
being a view of the snail at the letters referring to the same parts as in Figures 1.
and 2.
By preference the exhibits are placed on cards which are suitably laced together
edge to edge as shewn in Figure 3. and the cards or otherwise are moved down or
up between guides (f.) which may extend right across the cards at the back and
may consist of strips of metal or suitable material at the sides in the front of the
cards or of a sheet of glass in front. The guides are placed on the downward
motion of the cards and lead then into a rectangular curved passage. (9. g.) in which
they are folded to and fro by their falling motion and are moved through the said
passage to the point where they are drawn up by the roller (b), by their own
gravity and the excess of weight of cards in the entering end of the said
passage (g. ). The arrows shew the direction of the preferably endless string of
cards (h. h. h. h). The main spring in the drawing is compounded of several coils
in order to obtain conveniently a spring capable of winding many turns. for main-
taining the motion of the apparatus for a sufficient length of time.
The example shewn (Fig. 7) consists of five such sections (i. ¹³) which are
ordinary clock springs.
The coil () is fastened on the inside to the spindle (c) by means of a headed
stud (j) and on the outside to a headed stud (1) fixed in a tube (k). The coil (i)
is fixed on the outside by a headed stud (2) to the tube (k) and on the inside to a
headed stud (3) fixed in a tube (1) which is loose on the spindle (c). The coil (i³)
is fixed on the inside to a headed stud (*) on the tube (4) and on the outside to a
headed stud (3) on a third tube (¹). The coil () is fixed on the outside to a
headed stud (2) in the tube (¹) and on the inside by a headed stud (7) to a fourth
tube (1) also loose on the spindle. The coil (*) is fixed on the inside to a tube ("")
by a headed stud (3) and on the outside to a headed stud (2) in the spring barrel (a)
thus completing the series. The tubes (k) and (4) are free to rotate in the spring
barrel.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
:-
First-The arrangement and method of forming the string of cards or other
materials and the method of folding and storing the same in the aforesaid passage,
together with the guides for the card string separately or combinedly for the purpose
named substantially as shewn and described.

page_text: Second-The arrangement of the compound main-spring and the method of
coupling the sections of the same substantially as shewn and described.
Third-The stop and let off motions to the driving train or trains substantially
as shewn and described.
Fourth: The general combination and arrangement of the several and respective
parts together constituting our invention of an improved mechanical advertising.
apparatus, substantially as shewn and described.
