Improvements in Advertising Apparatus.
I, GEORGE ROBERT HERTSLET of 18 Royal Road, Teddington in the County of
Middlesex, Surveyor do hereby declare the nature of this invention to be as
follows:-
This invention relates to a new or improved form of advertising apparatus
applicable more especially to vehicles vessels and places subject to a certain amount
of vibration such vibratory motion supplying the motive power for operating the
mechanism and thus effecting the exposure of a series of advertisements in regular
rotation.
The apparatus consists preferably of a rectangular frame or box of a convenient
depth the front of such frame having a slot formed therein of the dimensions of
the advertisement to be exposed.
The series of advertisements are printed or affixed to a revolving disc mounted
upon a central axis which axis also carries a star wheel the points of which coincide
with the number of advertisements or advertising spaces on the disc.
The star wheel is adapted to engage with a series of pegs mounted upon a ratchet
wheel the latter being caused to revolve intermittently by means of a pawl pivotted
to a lever the fixed end of which is elastic and the free end of which is weighted.
When the vehicle say an omnibus is in motion such motion imparts a vertical up
and down motion to the weighted lever and the pawl pivotted thereto turns the
ratchet wheel the pegs of which as they come in contact with the points of the
star wheel cause the same to revolve and thus effect a change of advertisement.
To retain the advertisement in position after each change a drop pawl is arranged
which drops between the points of the star wheel at each change and is locked by
means of a pin projecting from a drop lever which is raised immediately by one of
the pins on the ratchet wheel before each change of advertisement, thus leaving the
pawl free to ride over the inclined surface of the succeeding point of the star.
Dated this 12th day of January 1891.

COMPLETE SPECIFICATION.
Improvements in Advertising Apparatus.
I, GEORGE ROBERT HERTSLET of 18, Royal Road, Teddington in the County
of Middlesex, Surveyor 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 a new or improved form of advertising apparatus
applicable mo e especially to vehicles vessels and places subject to a certain amount
of vibration, & ich vibratory motion supplying the motive power for operating the
mechanism an thus effecting the exposure from time to time of a series of
advertisements n regular rotation.
The apparati consists preferably of a rectangular frame or box of a convenient
depth the front of such frame having a slot or slots formed therein of the dimensions
of the advertisement to be exposed. The series of advertisements are printed or
affixed to a revolving disc mounted upon a central axis which axis also carries a
. 077

page_text: star wheel the points of which coincide with the number of advertisements or
advertising spaces on the disc.
The star wheel is adapted to engage with a series of pegs mounted upon
a ratchet wheel, the latter being caused to revolve intermittently by means
of a pawl pivotted to a lever the fixed end of which is elastic and the free
end of which is weighted. When the vehicle, say an omnibus, is in motion,
such motion imparts a vertical up and down motion to the weighted lever and
the pawl pivotted thereto turns the ratchet wheel the pegs of which as they
come in contact with the points of the star wheel cause the same to revolve and
thus effect a change of advertisement. To retain the advertisement in position after
each change a drop pawl is arranged which drops between the points of the star
wheel at each change and is locked by means of a pin projecting from a drop lever
which is raised immediately by one of the pins on the ratchet wheel before each
change of advertisement, thus leaving the pawl free to ride over the inclined surface
of the succeeding point of the star.
And in order that this my invention may be fully understood reference is had to
the accompanying illustrative sheets of drawings similar parts in each of the figures
being referred to by like letters of reference.
In the drawings annexed hereto,
Fig. 1 is a plan view of a construction according to this invention the back cover
of the case being shown hinged and open.
Fig. 2 is a view of the face of the casing showing one open advertisement space.
Fig. 3 is a vertical transverse section at line A. B. Figs. 1 and 2.
a is the frame or boxing, the back cover being hinged conveniently, at a¹; b is
the open advertisement space upon the front of such frame. c is the revolving disc,
upon the face whereof are arranged the advertisement devices or announcements
cis the central axis for said disc and of the star wheel d; said axis being carried and
free to turn in a bush e, carried upon a fixed dividing plate or screen f. This plate f
is exposed in Fig. 1. and carries the working parts which I will next describe.
The points of the star wheel correspond to number of the series of advertise-
ments to be displayed (six are shown in the drawings) g is the ratchet wheel carrying
the pegs which will from time to time strike the points of the star wheel to turn
same. The ratchet wheel g is caused to revolve intermittently by the pawl h, see
Fig. 1, weighted at ' and pivotted to the lever i having the spring tail portion k
secured in the holding pillars 7 so as to render said lever i elastic. The free end of
lever i carries the weight and a piercing of the ear 2 is threaded by the guide
wire or curved bar is forming an arc controlling the action of the free end of lever i
and with it the actuating pawl h. mis a check pawl to ensure the working of the
ratchet wheel g in the proper direction to effect the turning of the star wheel by the
pegs g¹.
n is the drop pawl arranged to fall between the points of the star wheel
at each movement of the advertisement so as to retain the display disc or wheel c in
stationary position until the next action of the vibrating lever i and its pawl h,
takes place. The drop pawl n works upon the same centre n' upon which is mounted
and works the drop lever o, the nose o' of which extends out so as to come into
contact with and be raised successively by the pins g of the ratchet wheel g.
immediately before each change of advertisement takes place.
As the lever o rises the pin o' thereof is lifted off the drop pawl n so leaving
same free to be raised as the points of the star wheel are turned.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is.
1st. The improvements in advertising apparatus characterised by the actuating-
lever and pawl, acting to turn the ratchet wheel and star wheel of the advertise-
ment disc, the operation being effected by the vibrating movement of a vehicle or
conveyance or such like moving body as and for the purpose herein specified and
shown by the drawings.

page_text: 2nd. In apparatus as herein described the frame a with the dividing plate fƒ with
its display openings the revolving disc c, star wheel d operated by the ratchet
wheel g g the pawl h and elastic operating lever i for communicating the vibratory
motion of said lever to the mechanism substantially as herein set forth.
3rd. In apparatus as herein set forth the check pawl n the drop lever o o' working
in combination with the star wheel d and ratchet wheel g g' as and for the purpose
herein specified.
