Improvements in and relating to Apparatus for Displaying
Advertisements, and for other like purposes.
I, WILLIAM ROBERT LAKE, of the Firm of Haseltine Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, do hereby declare
the nature of this invention to be as follows:-
This invention relates to apparatus for displaying advertisements and for other
like purposes.
The said invention has for its object to provide an apparatus for automatically
rolling up a strip or web of fabric such as cloth, canvas, paper or ribbon upon
one roller or cylinder whilst the same is unrolled from another roller or cylinder.
The chief feature of the invention relates to the means whereby the winding
operation is stopped and continued at equal or other predetermined intervals of
time and automatically reversed when the said cloth, canvas, paper or ribbon is
completely rolled up upon one roller and unrolled from the other.
The said apparatus therefore comprises two rollers or cylinders having rolled
thereon a strip, ribbon or web of cloth, canvas or other fabric which may be
provided with a series of advertisements, pictures or the like. The said rollers
may be arranged in a suitable casing having an opening or window which allows
the said advertisements or the like to be successively seen one at a time. According
to this invention improved means are provided for rotating the aforesaid rollers or
cylinders in the same direction and for causing the direction of rotation to be
automatically reversed as soon as the aforesaid strip or ribbon of web or fabric is
completely unrolled from one of the cylinders or rollers and rolled upon the other,
and also means for automatically stopping and starting the rotation of said rollers
or cylinders at equal or other predetermined intervals of time and for rolling and
unrolling equal or other predetermined lengths of the said cloth, canvas or other
fabric between the successive stoppages of the same.
In order that the nature of the invention may be more readily understood I
will now proceed to describe by way of example one form of the apparatus as
shewn in the accompanying drawings, in which,
Figure 1 is a front elevation and
Figure 2 a side elevation of the apparatus.
Figure 3 is a side view drawn to an enlarged scale of the stopping and starting
device.
Figure 4 shows the same device in vertical section.
Figure 5 is a front view also to an enlarged scale of the device for reversing the
rotation of the rollers.
Figure 6 is a side view of the same device.
Figure 7 is a front view of the device intended to lift the hammer T.
B and B are rollers or cylinders on which the strip or ribbon of cloth canvas
or other fabric A' which is secured by any suitable means whatever to a perforated
metallic ribbon A, is alternately rolled and unrolled.
The axis of the roller B' is provided with a conical pinion gearing into a
conical gear wheel C' which is free to turn on the driving axis D. The axis of
the roller or cylinder B2 carries a conical pinion which gears into a conical gear
wheel C2 which is also free to turn on the driving axis D. The said driving axis D
may be rotated by any suitable means whatever; in the drawing the motive power

page_text: is indicated by a weight E acting upon a chaine which is rolled up around the
axis F the wheel F of which acts, through the wheels ƒƒ`ƒ ƒ³ upon a bevel
wheel secured on the axis D.
From the above description it would appear that the axis D is always rotated in
the same direction if it is not stopped by the device hereinafter described.
The rotation of the said axis D is transmitted to the rollers or cylinders B
and B2 so as to cause the ribbon A and the cloth canvas or other fabric A' to be
rolled upon or unrolled from the said rollers or cylinders alternately. This
movement is obtained by means of the following device, which transmits the
rotation of the axle D to the gear wheel C' and to the gear wheel C² alternately.
The conical gear wheels C and C2 are provided with pawls e¹ and e² respectively,
acted upon by springs and c. The pawl is caused by its spring to engage with
a ratchet wheel & fixed to the axle D, and the pawl e to engage with the teeth of
the ratchet wheel which face in the opposite direction to those of the ratchet
wheel d', and a tubular axle D' with conical ends d³ and produces by its
longitudinal displacement on the axis D and by means of the said cones d³ and d
the disconnection of the pawl e and of the pawl c² alternately.
The rotation of the axis D therefore causes the rotation of the roller or
cylinder B and also the rotation of the roller or cylinder B in alternate directions
when the tube D' is automatically displaced. This displacement of the tube D' is
ensured by the following devices :
The perforated metallic ribbon A when being rolled up either on the roller or
cylinder B or on the roller or cylinder B2 causes the rotation of the toothed'
wheel G by means of the perforations a. A wheely keeps the perforated ribbon A
in gear with the teeth of wheel G. The wheel G acts, either directly or by means
of a wheel-work as shown in the drawing, upon a disc o the outer face y³ of which
is inclined with respect to the axis of said disc gl as shewn in Figure 5.
Said disc g bas moreover a pin or projection 9. In front of said disc g' is an
axis i one end of which is supported in a bearing in the bracket I. The axis i
carries a pendulum or hammer 1 and is so arranged as to be continually pressed
towards the inclined face of the disc g' by means of a spring it. The said
axis is therefore acted upon and displaced by the inclined plane g³ when the
disc is rotated.
When the axis bears upon the top of the wedge ³ the pendulum or hammer I
oscillates in a vertical plane in which it does not act upon the lever K, but when
the axis bears upon the lower part of the wedge o³ the hammer I oscillates in the
same vertical plane as the coupling lever K and it therefore strikes the same if it
is oscillated.
The hammer or pendulum I carries a lateral projection which is acted upon by
the pin or projection of the disc and owing to the action of the pin or
projection upon the lateral projection the hammer 1 is lifted.
The axis of the hammer of pendulum I, being situated somewhat higher than
the axis of the disc g¹ the paths of the lateral projection and the pin g² are two
arcs at the intersection of which the projection will escape from the pin g² thus
causing the falling down of the bammer I.
The lever K is in operative connection with the sleeve D' so that when the said
lever is operated the sleeve is moved up or down thus causing the pawl cor
pawl as the case may be to connect with its ratchet wheel. The spindle D is
therefore connected with the bevel wheel C¹ or bevel wheel C².
The reversal of rotation of the rollers B1 and B2 respectively necessarily involves
a reversal of rotation of the wheel G, of the disc y' and of its projection g², the
hammer I thereby being lifted into a position opposite to its former one and its
next fall will replace the rocking-lever K in its former position causing again a
reversal the direction of rotation of the rollers or cylinders B¹ and B².
The stopping or starting of the cloth, canvas or other ribbon after a pre-
determinated space of time is effected by means of the following devices:
Two discs M and M' provided with a notch shaped like a tooth or hook are

page_text: secured upon the axis of the wheel G or upon an intermediate axis m' connected
with the former by means of suitable gearing. Pawls N N are provided to engage
with the notches on the discs M, M' respectively. The notch of the disc M is
intended to stop the wheel G when it rotates in one direction, and the notch of the
disc M is intended to stop it when it rotates in the other direction. The discs M
and M are not directly keyed upon the axis m' which bears them; as shown in
Figure 3 the axis m' upon which the wheel m is keyed, carries two pins m², m³
which are caused to engage in a notch m' provided in the nave of each disc M, M¹.
When the
Those discs are connected with one another by means of a spring m³.
axis m' turns in the direction of the arrow in Figure 3 and when the disc M' is
stopped by the pawl N' said axis m' is not stopped suddenly but it keeps turning
while the pin m³ passes from one edge of the notch m to the other, which will
take place in bending the spring m³. The shock produced by the stoppage of the
ribbon is thus elastically weakened. The simultaneous stopping of the rollers or
cylinders B & B2 and of the above described device occurs as follows. A rod O
bearing by means of the pin o upon the pawls N and N¹ is connected at both ends
by means of screws of and o² or of any other suitable connection, to pawls and p'.
The rollers or cylinders B and B are provided with toothed wheels 63 and 64
which gear with the pinions and 6. The axles of the pinions and are
secured by means of a spring like the discs M and M' upon dises and 65 provided
with a suitable number of stop teeth. When the pawls p and p' are not lifted by
the rod their teeth coming in the path of one of the teeth of the discs and
causes the stopping of the rollers B₁ and B².
The perforated metallic ribbon A is intended to regulate, by means of its
openings a, the regular advancement of the cloth, and to prevent the same being
stretched by the tension necessary for the good working of the apparatus.
The starting of the apparatus is as follows:-
There is provided a clock-work train which has fixed to its driving axis an
eccentric R upon which (under the action of a suitable spring) bears the arms of
a lever S having two teeth s¹ and 2. These teeth successively engage the end T¹
of the rod T which carries a hammer T pivoted to an axis t.
The cud T of said rod T2 is formed like a bell crank and bears upon the
teeth of the lever S when the arms of the latter bears upon one of the lower
parts of the eccentric R. Now if the top of the said arns of the lever S is
Oscillated so that its tooth s¹ is retracted out of reach of the end of the rod T¹
the latter then engages with the tooth s² of the lever S. The rotation of the
eccentric R then causes the arms to again engage with one of its lower portions
and to cause the lever S to oscillate so as to retract its tooth s² out of reach of
the lever T the hammer T then resting upon the arm of a rocking-lever V
placed underneath.
The other extremity of the lever V is provided with an arm placed in a
position opposite to the arm e. When the arm is lowered by the fall of the
hammer T, the arm is lifted and carries away the rod L hanging in a suitable
way from the end of the lever . The lower end of the rod L being connected
in any suitable manner, as in the drawing for instance by a pin with the levers N
and N the fall of the hammer causes the throwing out of gear of the discs M
and M and therefore the starting of the whole apparatus until the levers N and N¹
will fall back in the notch of the discs M and M.
The lifting again of the hammer T is obtained by the device shown in Figure 7.
When the hammer T is just about to strike thus causing the starting of the
mechanism, the end T2 of the hammer T falls against the heel u' of the pawl u of
the ratchet wheel U keyed upon the axis of the wheel and presses the pawl u
into the ratchet teeth Ů. The pawl u being fixed upon a disc U' turning freely
on the axis of the wheel ", it follows that the latter is carried away in its
rotation by the ratchet U and that the heel u' of the pawl, pressing upon the
end T2 of the hammer T lifts the latter again high enough to replace it upon
the tooth s. Then the eccentric projection u² of the pawl u coming in contact

page_text: with the pulley u³ disengages the pawl from the teeth of the ratchet wheel U
and a spring u takes suddenly the disc U¹ into its former position determined by
means of the spur u³.
The hammer T being thus lifted the lever V takes again its normal position
and it follows that the pawls will be enabled to work again as soon as the discs M
and M will have accomplished their stroke and will present the catch for the
tooth of the levers N and N' to engage in.
Although I have herein above described a very suitable form of apparatus for
carrying out my invention, I may alter the same in detail without departing from
the nature of my said invention.

I, WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 apparatus for displaying advertisements and for other
like purposes.
The said invention has for its object to provide an apparatus for automatically
rolling up a strip or web of fabric such as cloth, canvas, paper or ribbon upon one
roller or cylinder whilst the same is unrolled from another roller or cylinder, the
said apparatus being arranged so that the said operation may be stopped and
continued at predetermined intervals of time and automatically reversed when the
said cloth, canvas, paper or ribbon is completely rolled up upon one roller and
unrolled from the other.
The said apparatus therefore comprises two rollers or cylinders having rolled
thereon a strip, ribbon or web of cloth, canvas or other fabric which may be
provided with a series of advertisements, pictures or the like. The said rollers
may be arranged in a suitable casing having an opening or window which allows
he said advertisements or the like to be successively seen one at a time.
According to this invention means are provided for rotating the aforesaid rollers
or cylinders in the same direction and for causing the direction of rotation to be
automatically reversed as soon as the aforesaid strip or ribbon of web or fabric is
completely unrolled from one of the cylinders or rollers and rolled upon the other,
and also means for automatically stopping and starting the rotation of said rollers
or cylinders at equal or other predetermined intervals of time and for rolling and
unrolling equal or other predetermined lengths of the said cloth, canvas or other
fabric between the successive stoppages of the same.
In order that the nature of the invention may be more readily understood I have
shown one form of the apparatus by way of example in the drawing left with my
Provisional Specification, in which
Figure 1 is a front elevation of the improved apparatus.
Figure 2 a side elevation of the same.
Figure 3 is a side view drawn to an enlarged scale of the stopping and starting
device.
Figure 4 shows the same device in vertical section.
Figure 5 is a front view also to an enlarged scale of the device for reversing the
rotation of the rollers.
Figure 6 is a side view of the same device.

page_text: Figure 7 is a front view of the device intended to lift the hammer T.
B and B are rollers or cylinders on which the strip or ribbon of cloth canvas
or other fabric A', which is secured by any suitable means to a perforated metallic
ribbon A, is alternately rolled and unrolled.
The axis of the roller B' is provided with a conical pinion gearing into a
conical gear wheel C' which is free to turn on the driving axis D. The axis of
the roller or cylinder B2 carries a conical pinion which gears into a conical gear
wheel which is also free to turn on the driving axis D. The said driving axis D
may be rotated by any suitable means whatever; in the drawing the motive power
is indicated by a weight E acting upon a chain e which is rolled up around the
axis F the wheel F of which acts, through the wheels ff¹ƒ ƒ³ upon a bevel
wheel secured on the axis D.
From the above description it would appear that the axis D is always rotated in
the same direction if it is not stopped by the device hereinafter described.
The rotation of the said axis D is transmitted to the rollers or cylinders B' and B
so as to cause the ribbon A and the cloth canvas or other fabric A¹ to be rolled
upon or unrolled from the said rollers or cylinders alternately. This movement is
obtained by means of the following device, which transmits the rotation of the
axle D to the gear wheel C and to the gear wheel C².
The conical gear wheels C¹ and Care provided with pawls cl and c² respectively,
acted upon by springs 3 and 4. The pawl e' is caused by its spring to engage
with a ratchet wheel d¹ fixed to the axle D, and the pawl e² to engage with the
teeth of the ratchet wheel which face in the opposite direction to those of the
ratchet wheel d, and a tubular axle D' with conical ends d³ and d produces by its
longitudinal displacement on the axis D and by means of the said cones d³ and d
the disconnection of the pawl e¹ and of the pawl e² alternately.
The rotation of the axis D therefore causes the rotation of the roller or
cylinder B' and also the rotation of the roller or cylinder B2 in alternate directions
when the tube D' is automatically displaced. This displacement of the tube D' is
ensured by the following devices :
The perforated metallic ribbon A when being rolled up either on the roller or
cylinder or on the roller or cylinder B2 causes the rotation of the toothed
wheel G by means of the perforations a. A wheel y keeps the perforated
ribbon A in gear with the teeth of wheel G. The wheel G acts, either directly
or by means of a wheel-work as shown in the drawing, upon a disc y' the outer
face 3 of which is inclined with respect to the axis of said disc as shewn in
Figure 5.
Said disc g has moreover a pin or projection . In front of said disc g¹ is an
axis one end of which supported in a bearing in the bracket I. The axis i
carries a pendulum or hammer I and is so arranged as to be continually pressed
towards the inclined face g³ of the disc g' by means of a spring it. The said axis i
is therefore acted upon and displaced by the inclined plane g³ when the disc g' is
rotated.
When the axis bears upon the top of the wedge g³ the pendulum or hammer I
oscillates in a vertical plane in which it does not act upon the lever K, but when
the axis bears upon the lower part of the wedge y³ the hammer I oscillates in the
same vertical plane as the coupling lever K and it therefore strikes the same if it
is oscillated.
The hammer or pendulum I carries a lateral projection which is acted upon
by the pin or projection of the disc g and owing to the action of the pin or
projection upon the lateral projection the hammer I is lifted.
The axis of the hammer of pendulum I, being situated somewhat higher than
the axis of the disc g the paths of the lateral projection and the pin g² are two
arcs at the intersection of which the projection will escape from the pin g² thus
causing the falling down of the hammer f.
The lever K is in operative connection with the sleeve D' so that when the said
lever is operated the sleeve is moved up or down thus causing the pawl e¹ or

page_text: pawl as the case may be to connect with its ratchet wheel. The spindle D is
therefore connected with the bevel wheel C¹ or bevel wheel C².
The reversal of rotation of the rollers B and B respectively necessarily
involves a reversal of rotation of the wheel G, of the disc g and of its pro-
jection 2, the hammer I thereby being lifted into a position opposite to its
former one and its next fall will replace the rocking-lever K in its former position
causing again a reversal of the direction of rotation of the rollers or cylinders B¹
and B2.
The stopping or starting of the cloth, canvas or other ribbon after predetermined
-spaces of time is effected by means of the following devices:
Two dises M and M' provided with a notch shaped like a tooth or hook are
secured upon the axis of the wheel G or upon an intermediate axis m' connected
with the former by means of suitable gearing. Pawls N N are provided to
engage with the notches on the discs M, M¹ respectively. The notch of the disc M
is intended to stop the wheel G when it rotates in one direction, and the notch of
the disc M' is intended to stop it when it rotates in the other direction. The
discs M and M' are not directly keyed upon the axis m' which bears them; as
shown in Figure 3 the axis m' upon which the wheel m is keyed carries two
pins m², m³ which are caused to engage in a notch m provided in the nave of each
disc M, M. Those discs are connected with one another by means of a spring m³.
When the axis m³ turns in the direction of the arrow in Figure 3 and when the
disc M¹ is stopped by the pawl N' said axis m' is not stopped suddenly but it keeps
turning whilst the piu m³ passes from one edge of the notch m' to the other, which
will take place in bending the spring me. The shock produced by the stoppage
of the ribbon is thus elastically weakened. The simultaneous stopping of the
rollers or cylinders B and B and of the above described device occurs
follows: A rod O bearing by means of the pin upon the pawls N and Nis
connected at both ends by means of screws o' and of or of any other suitable
connection, to pawls pand. The rollers or cylinders B and B are provided
with toothed wheels 3 and 4 which gear with the pinions and . The axles of
the pinions and 66 are secured by means of a spring like the discs M and M
upon dises and provided with a suitable number of stop teeth. When the
pan Is p and pare not lifted by the rod O their teeth coming in the path of one
of the teeth of the discs 7 and 8 causes the stopping of the rollers B1 and B.
as
The perforated metallic ribbon A is intended to regulate, by means of its
openings, the regular advancement of the cloth, and to prevent the same being
stretched by the tension necessary for the good working of the apparatus.
The starting of the apparatus is as follows:
There is provided a clock-work train which has fixed to its driving axis an
eccentric R upon which (under the action of a suitable spring) bears the arms of
a disc S having two teeth s' and s. These teeth successively engage the end T' of
the rod T2 (which carries a hammer T) pivoted to an axis t.
The end T of said rod T2 is formed like a bell crank and bears upon the
teeth of the disc S when the arms of the latter bears upon one of the lower
parts of the eccentric R. Now if the top of the said arms of the disc S is
oscillated so that its tooth & is retracted out of reach of the end of the rod T¹ the
latter then engages with the tooth 2 of the lever S. The rotation of the
eccentric R then causes the arms to again engage with one of its lower portions
and to cause the lever S to oscillate so as to retract its tooth out of reach of
the lever T¹ the hammer T then resting upon the arm of a rocking-lever V placed
.underneath.
The other extremity of the lever V is provided with an arm V³ placed in a
position opposite to the arm v. When the arme is lowered by the fall of the
hammer T, the arm 3 is lifted and carries away the rod L hanging in a suitable
way from the end of the lever 3. The lower end of the rod L being connected in
any suitable manner, as in the drawing for instance by a pin with the levers N
and N¹ the fall of the hammer causes the throwing out of gear of the discs M

page_text: and Mand therefore the starting of the whole apparatus until the levers N and N¹.
will fall back in the notch of the discs M and M.
The lifting again of the hammer T is obtained by the device shown in
Figure 7.
When the hammer T is just about to strike thus causing the starting of the
mechanism, the end T of the hammer T falls against the heel al of the pawl of
the ratchet wheel U keyed upon the axis of the wheel and presses the pawl
into the ratchet teeth U. The pawl u being fixed upon a disc U turning freely
on the axis of the wheel, it follows that the latter is carried away in its.
rotation by the ratchet U and that the heel of the pawl, pressing upon the.
end T of the hammer T lifts the latter again high enough to replace it upon the
tooths. Then the eccentric projection of the pawl u coming in contact with
the pulley disengages the pawl from the teeth of the ratchet wheel U and a.
spring takes suddenly the disc U₁ into its former position determined by means
of the spur
The hammer T being thus lifted the lever V takes again its normal position and
it follows that the pawls will be enabled to work again as soon as the discs M
and M will have accomplished their stroke and will present the catch for the tooth
of the levers N and N¹ to engage in.
Although I have hereinabove described a very suitable form of apparatus
for carrying out my invention I may alter the same in detail without departing
from the nature of my said invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim in an apparatus for
automatically winding a strip of canvas or other fabric and regularly unwinding
the same, is
1st. The combination of the driving axis D with gear wheel C and C³ pawls
and ratchets ' and the rollers or cylinders B and B with pawls and
the perforated metallic ribbon A, the cloth, canvas or other fabric A', the toothed
wheel, discs M and M' and levers N and N' substantially as described and for
the purpose specified.
2nd. The combination of the disc gl bearing a pin or projection 9² and a wedge
piece 3 with a hammer I the axis of which is situated somewhat higher than the
axis of the disc y' and which bears a lateral projection and with a disconnecting
lever acting upon the tube D' substantially as described and for the purpose
set forth.
3rd. The combination of a suitable clock work train arranged so as to precise
the length of each stoppage of the rollers or cylinders B and B and their
starting, substantially as described.
