I, ROBERT JAMES WOOD, of 108, Argyle Street, in the County of the City
of Glasgow, North Britain, Clockmaker, do hereby declare the nature, of this
invention to be as follows:-
This invention relates to improvements in apparatus for displaying advertise-
ments, which is operated by water power.
In carrying out my invention I provide a framework across the back and front
of which there is a set of rollers. There are or may be two, three or more sets of
such rollers placed on the framework at a convenient distance above each other.
At one end of the framework opposite each set of rollers and resting on a suitable
bracket there is a cylinder having a piston working therein. Con-
nected to this cylinder there is a pipe leading from the main or
other source of supply. As the water enters the cylinder it raises the
piston and as it rises it operates a forked lever, which is connected
to a clutch working on same centre as the driving wheel. This opera-
tion causes the driving or spur wheel to make a fourth or other arranged part of a
revolution and thereby revolves the first set of rollers, which are geared with said
driving wheel by means of a pinion or otherwise, and so calculated as to make a
complete revolution for the fourth or other part of a revolution made by the
driving wheel. Each set of rollers are so geared to each other as to ensure their
working simultaneously. On the piston reaching the top, the valve is closed and
the water cut off by means of a tumbling-lever operating, through arms or levers,
arms attached to the valves or cocks and by means of a catch kept in position.
The piston is depressed and the water discharged by a weighted lever or arm
and on reaching the bottom, the tumbling arm falls in an opposite direction and
in doing so, by disengaging a catch attached to the valve or cock of the cylinder
connected with the second set of rollers, opens the valve and admits water into
this cylinder and the piston rises and operates the mechanism in a precisely
similar manner to the former set as already described. The outlet is so arranged
that longer or shorter time may elapse in the discharging or emptying of the
cylinders. When the piston of this second cylinder reaches the bottom, the
tumbling arm or lever, by means of a wire or cord or other suitable arrange-
ment, releases the catch which prevents the water from entering the first cylinder.
The same operation goes on continuously until the top set of rollers are reached
when the bottom cylinder, being connected with the top is again put into motion
by the releasing of the catch as already described.
Suitable overflows are provided in the cylinders.
The advertisements which are placed round the sets of rollers revolve so long
as the set is in motion. The advertisements on each set of rollers may be placed
on one sheet of canvas or other suitable material, or in separate sheets and they
may be connected to chains, cords, or otherwise for communicating the motion
from one roller to the other.

page_text: I also provide revolving electric lamps of different colours on the framework.
They are so arranged that the revolving of the rollers operate the lamps thereby
causing them to revolve at the same time.

Improvements in Apparatus for Displaying Advertisements.
I, ROBERT JAMES WOOD, of 108, Argyle Street, in the County of the City
of Glasgow, North Britain, Clockmaker, 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 improvements in apparatus for displaying advertise-
ments, which is operated by water power.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended one sheet of drawings, of which.
Figure 1 is an end view of the apparatus, and
Figure 2 is a front elevation of the apparatus.
Figure 3 is a side elevation and plan respectively of a detail of the mechanism
hereinafter more fully described.
Figure 4 is a side elevation of a further detail also hereinafter more fully
described.
In carrying out my invention I provide a framework A across the back and
front of which there is a set of rollers B. Each set of rollers B are mounted
with an advertising device B* or a series of advertising devices. There are or
may be two three or more sets of such rollers carried on the framework at a con-
venient distance above each other. At one end of the framework opposite each
set of rollers and resting on a suitable bracket there is a cylinder C having a
piston D working therein. Connected to this cylinder C is
a pipe E
leading from the main or other source of supply. As the water enters the
cylinder C it raises the piston 1) and as it rises it operates a forked lever N which
gives motion to an axle or spindle G upon which is mounted a rocking bar G¹,
which is connected to a pawl G which gears with a sprocket wheel G working on
same centre as the driving wheel H. This operation causes the driving or spur
wheel H to make a fourth or other arranged part. of a revolution and thereby
revolves the first set of rollers B, which are geared with said driving wheel H by
means of a pinion I or otherwise, and so calculated as to make a complete revolu-
tion for the fourth or other part of a revolution made by the driving wheel H.
Each set of rollers are so geared to each other as to ensure their working simul-
taneously. On the piston I reaching the top of its stroke the valve J is closed
and the water completely cut off. A tumbling lever R, which is loosely mounted
on the spindle G and rocks between the two studs 1 and 2 projecting from the
quadrant which is rigidly fixed to the aforesaid spindle G, assists in the operation
for when the piston is at the top of the cylinder and has commenced to descend the
quadrant g by means of the pin g¹,has thrown the tumbling lever R and with it its
weight on the stud 9 of the quadrant 9 which causes the spindle G to quickly
turn upon its axis and relatively with this movement an arm P which is co-axial
with it, descends as well as the lever L which is connected to the lever M and
which is again connected to the stem of the valves or cocks by which means the
downward stroke is greatly expedited. The said lever.M is provided at its outer
end with a curved projection by which it is momentarily locked as now to be

page_text: described. The closing of the inlet valve simultaneously opens the discharge
valve, this valve having a three-way cock.
Referring to the upper cylinder C as illustrated on Figure 1, the inlet port
leading to the cylinder C is open for the admission of water, which enters at the
bottom as shown. The rise of the piston rod D¹ by means of projecting studs d
causes the fork N to turn the spindle Gupon its axis, which operation raises the
lever P which is mounted upon and turns with the said spindle G, and with it
is raised the slotted extension L which is connected to the outer end of the valve
lever M aforesaid, the valve lever M, being raised to a predetermined height,
engages with the short vertical locking lever O which for the time being ensures
the water being positively cut off and kept so.
Further with the rise of the said piston the engaging end of the lever P,
seen more particularly in Figure 3, is caused to rise relatively with it. The
rise of the lever P would be retarded when it came in contact with the engaging
end P of the weighted lever Q, which is pivoted on the fulcrum P³ this however
is obviated by virtue of the deer foot form of joint operating only by a rising
motion with which the lever P is provided which is so constructed that its outer
end becomes depressed, as shown in dotted lines in Figure 3, when in contact
with P and so the lever is enabled to rise until the piston has completed its
stroke. The cylinder becoming exhausted of water discharging itself by gravity
by the outlet or exhaust pipe E at the bottom of the cylinder begins to suddenly
descend with the aid of the weighted lever R moving from a state of equilibrium
to the one side as already referred to. The lever P also descends when it comes
in contact with the engaging surface P₁ of the weighted lever Q aforesaid, which
does not permit of its passing clear, but is acted upon in such a manner as to
cause the outer end P of the weighted lever P¹ to rise. The rising of the outer
end P of the lever P¹ by means of a connecting wire, cord, or chain S has effected
the disengagement of the lower valve lever M by causing its bolt like end to be
released from the lower vertical locking lever O, which is moved outwardly in the
direction indicated by the arrow end, which opens the port for an admission of water
to the lower cylinder, which in turn is acted upon in a similar manner. By the
alternate charge and discharge of the upper and lower cylinders and bringing into
operation the mechanism before described the upper and lower rollers are
periodically revolved and the advertisements alternately changed.
Suitable overflows are provided in the cylinders.
The advertisements, which are placed round the sets of rollers revolve so long
as the set is in motion. The advertisements on each set of rollers may be placed
on one sheet of canvas or other suitable material, or in separate sheets and they may
be connected to chains, cords, or otherwise for communicating the motion from one
roller to the other. In the drawings I have shown the rollers B' mounted with
sprocket wheels 12 which engages with the eyelets B³ formed on the one. side of
the advertising screen.
I also provide revolving electric lamps, not shown in the drawings of different
colours and intended to be mounted on the framework T, which has a spindle U
which receives rotary motion from the roller by means of a pinion V, which gives
motion to a shaft W mounted with a worm X, which said worm gives motion to
a tooth wheel Y in order to operate the spindle U aforesaid. The lamps are so
arranged that the revolving of the rollers operate them thereby causing them to
revolve at the same time.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. An apparatus for displaying advertisements, consisting of a framework across
the back and front of which there is a set or a number of sets of rollers having
an advertising device, or a series of advertising devices, mounted thereon and
rotated by mechanism, which is operated by water power and so arranged that as

page_text: one set of rollers has completed its revolution the valve is closed and the water cut
off from the mechanism operating this set of rollers and the advertisement
remains stationary, the valve which operates the mechanism of the next set of
rollers is immediately opened and this mechanism is put into operation, and so
on till the whole of the set of rollers have been operated upon, when, by means
of a connecting rod from the top set of rollers to the bottom one, the lower set is
again operated upon as before, and so on so long as the water power is applied,
all substantially as described and shewn on the drawings.
2. In apparatus for displaying advertisements, the arrangement of revolving
electrical lamps operated substantially as described and illustrated on the
drawings.
3. In apparatus for displaying advertisements, the general arrangement and
operation of the parts all constructed substantially as described and illustrated on
the accompanying sheets of drawings.
