COMPLETE SPECIFICATION.
A Machine for Exhibiting and Displaying Moveable Advertisements,
Notices, or Pictures.
I HENRY LAURENCE PETERS, of Essex Villa, Cadogan Road, Surbiton, in the
County of Surrey, Gentleman, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to a machine for exhibiting and displaying moveable
advertisements, notices, or pictures, and for the purpose of, and as a means of,
attracting attention thereto, and consists of the peculiar features and combination
of parts, more fully described hereinafter and pointed out in the claims.
I construct one or more panels, of wood, metal or other suitable material, in
which are cut, one or more openings, slots or apertures, and behind such openings,
are mounted upon bearings, and each turning upon its axis, one or more drums,
either cylindrical or polygonal in form. These drums are constructed in a manner
convenient for the representation or reception thereon of notices, advertisements,
pictures, inscriptions, devices or designs, by the employment in connection there with
of paper, cards, glasses or other substances, transparent or opaque, suitable for the
exhibition of such notices, advertisements etc. In construction, these drums may
be made solid or hollow, or may be built up, of metal, wood or other suitable
material. The drums may be made of cylindrical shape with uniform circumference
throughout, or they may be made of polygonal form, and paper, card, linen, or
other suitable material for the representation of notices, advertisements, pictures,
inscriptions, or designs may be pasted on or otherwise affixed to the surface of the
drums, or such notices, advertisements, pictures, inscriptions and designs may be
painted or otherwise represented on the drums themselves. When constructing
the drums of metal, or of metal and wood combined, strips of metal, of the required
size, have their two opposite edges turned inward, so as to form a secure grip or
holding for either card, glass, or other suitable material, transparent or opaque,
which may be placed between these turned-in edges. These pieces of metal are
then joined or fastened to each other back to back, and when they are so joined,
are affixed to one or more metal or wooden circular or polygonal shaped ends'
corresponding in shape to the drum formed by the pieces of metal referred to.
Or in place of the metal strips just described, pieces of wood or metal may be
employed having grooves cut or moulded on their two opposite sides, and used in
sufficient number to complete the drum. They are then fastened to the circular or
polygonal shaped ends of the drum. The grooves so cut or moulded form a
grip or holding into which can be placed cards, glasses, or other suitable material,
either transparent or opaque.
The metal or wooden ends of the drums are then mounted on spindles carried on
suitable bearings.
Attached to the spindles of these drums are toothed wheels or pulleys by means
of which the drums can be revolved round their axes in either a forward or
backward direction.
To effect such revolutions an endless chain or other form of flexible connection
is employed which partly passes round, and is in gear with the toothed wheels or
pulleys attached to the spindles of the drums, and which also partly passes round
and is in gear with two other toothed wheels or pulleys mounted on spindles and

page_text: bearings. To make the intention of this invention clear one of these two other
toothed wheels or pulleys is referred to herein as the "actuating wheel."
Or as a means of effecting such revolutions, in lieu of the endless chain or other
flexible connection, referred to in the foregoing paragraph, the toothed wheels
attached to the spindles of the drums may be geared together, directly with each
other; or they may be geared with intermediary toothed wheels placed between
them; or the toothed wheel attached to the spindle of the drum may be geared
directly with the toothed' wheel described as the "actuating wheel," or with an
intermediary toothed wheel between it and the said actuating wheel.
For conveying motion to the "actuating wheel there is connected thereto a
wheel of peculiar formation; and for the purpose of distinguishing this wheel, it is
herein referred to as the driving wheel.'
'
This 'driving wheel is constructed with two flanges on, the e outer edges of its
periphery, and in these flanges are cut spaces, at suitable intervals, similar in form
to the spaces between the teeth of a ratchet wheel. In the rim, of the wheel,
formed by the space between the two flanges, are cut slots. Placed in such a
position that one end of it engages, or fits into, these slots, is a stop lever, mounted
at-its other end on a fulcrum or bearing. The projecting end of this stop; lever-is
turned up and forms a detent which fits into any one of the slots, and prevents the
driving wheel turning on its axis more than is required. This stop-lever is
held in the required position by the pressure, thereon of a spring-fixed in a
convenient position for so exerting its pressure. Mounted on a-bearing contiguous-
to, and in line with, both the stop lever and the driving wheel is a toothed
wheel, called herein, for the purpose of distinguishing it from other wheels, the
'toothed motive wheel'; partly round which passes, and with which is geared; an
endless chain, which is also supported by, and which passes partly round; a pulley
carried on a bearing fixed in a suitable position. To one or more- links of this
endless chain, are affixed one or more bolts, projecting in an outward direction
from the links of the chain, and, there are also, affixed to one or more links of the
said endless chain; one or more pins projecting, beyond the links of the chain on
both sides.
In the passage of that part of this endless chain with the bolt or bolts attached,
round the toothed "motive wheel" the projecting bolt or bolts bear on, or engage
with, the stop lever previously referred to, and by moving or depressing it; causes
the projecting detent end of the stop lever to disengage itself; from the slot in the
rim of the "driving wheel" in which it is 'placed, and it thus ceases to prevent
the free movement of the "driving wheel.". Upon the passage a certain distanee,
of the projecting bolt in the endless chain round the toothed "motive wheel" it
ceases to bear oni or engage with, the stop, lever, upon which the stop lever by the
pressure-against it of the spring, referred to previously, assumes such a position
that its projecting detent end again comes, in contact with the rim of the driving
wheel:'
'
In the meantime, and 'during, the passage oft the endless chain geared round the
toothed motive wheel' the projecting pin affixed in one of its links will have come
in contact with the edge of one of the ratchet like spaces, cut in each of the two
flanges of the driving wheel' and, in continuing its course, williby this contact,
have rotated the "driving wheel" to the extent required; and the projecting detent
end of the stop lever will, during this movement, rest against the rim of the
driving wheel until it is reached by the next slot cut therein and" into which the
detent end of the stop lever then engages.
ק
Where a single drum only is required the driving wheel can be affixed to the
spindle of the drum and thus impart the movement or revolution direct to the drum,
in which case the toothed wheel described as the actuating wheel' will not then
be required or necessary.
f
.
The object of the endless chain with bolts and pins attached 'to its links is, while
ensuring by its action a quick movement of the drums, to allow an interval between
such movement longer than the time occupied by the toothed motive wheel or motive

page_text: cam wheel-hereinafter 'described, in making a complete revolution, and the length
of such endless chaiu determines the length of the interval between each movement
of the drum or drums.
Where a very short interval is required between the movements of the drum or
drums, the use of additional bolts and pins at short spaces between them in the
endless chain will accomplish this.
6
In lieu of that part of the mechanism described in the foregoing as, and consisting
of, the toothed" motive wheel and also the endless chain with bolts and pins
attached and also the pulley supporting the said endless chain there may be
substituted, for the motive wheel a cam wheel'described herein, for the purpose
of distinction, as the "motive cam wheel which, in its rotation, will bear upon the
stop lever by means of a projection or cam in its periphery, and which will pass
between the two flanges of the driving wheel without disturbing same, and will
release its pressure on the stop lever as soon as it has rotated a sufficient, distance.
In the meantime, a pintor pins, projecting from the sides of the 'motive cam wheel
will have come into contact with the edge or edges of the spaces cut in the 'flanges
of the driving wheel and will have imparted thereto the necessary motion, which
motion will be arrested at the proper moment, by the detent end of 'the' stop lever
engaging that slot in the rim of the driving wheel' which is then approaching it.
When used in connection with the motive cam wheel, the form of the driving
wheel may also be varied if desired, in so far that it may be constructed without
two flanges, and consequently without slots cut in the rim between them, as
previously described;-instead, there can be cut in the periphery of the driving
wheel, spaces into which the pin or pins affixed to the motive cam wheel already
referred to, will travel when the motive (cam' wheel comes into radius with the
driving wheel and will thereby communicate its 'movement to the driving wheel;
the said pin or pins leaving the spaces when the one wheel passes out of the other's
radius. The same spaces cut in the periphery of the driving wheel for the admission
of the pin or pins attached to the motive cam wheel, will serve as spaces into which
the detent end of the stop lever' will fit and thus arrest the movement of the driving
wheel when necessary.
The uses of the cam and the pin affixed to the motive cam wheel, may ibe
reversed from the foregoing, that is to say, that the cam on the edge of the motive
cam wheel can be used to transmit its motion to the driving. wheel, in which case
the cam will engage in the spaces cut in the periphery of the driving wheel, and
the pin affixed to the side of the motive cam wheel can be utilised to effect the
necessary movement of the stop lever in a similar manner to that movement
obtained from the motion of the cam described in the previous paragraph.
The toothed motive wheel' (or the motive cam wheel' when the latter is
substituted for the former) can, either of them, be rotated by transmitting thereto
the power exerted by any convenient form of mechanism applicable 'thereto; such
as clockwork, fan électric motor, a motoripropelled by gas, water, steam or air, or by
the power transferred or conveyed from the revolving wheel or shaft of any machine
or vehicle that can be used therefore;or either of them can be turned 'by hand.
In the interior of the drum'or drums, when hollow, there can be placed electric
lamps with wires attached for conveying thereto the necessary electric current.
These lamps can be affixed to a collar which will be 'mounted or rest upon the
spindle of the drum, and the latter can freely revolve within the collar, without
changing or affecting the position of the electric lamp. The electric lamp cau be
held in position at any desired angle from the axis of the drum, by affixing to the
collar, to which the lamp is attached, a weight to act as counterpoise.
In addition to the drums and their connections 'as described in the foregoing 'or
in substitution of any part of such connections that can be omitted without
impairing the effective working of this machine, there can be carried on and over
the drums, endless flat bands of leather, 'canvas or other suitable flexible material.
In these bands can be cut holes at the required distances from each other, in which
are fitted 'metal eyelets, through which ordinary metal paper fasteners or other

page_text: suitable fastenings can be placed, for the purpose of securing thereto, cards, glasses,
or other substances or materials, transparent or opaque, and suitable for printing
or exhibiting upon their surfaces, notices, advertisements, designs, pictures or
inscriptions. Or, in place of these eyelets there can be attached to the flexible
bands metal clamps, by means of rivets or other suitable fastenings. These clamps
can be so constructed as to hold between them cards, glasses, or other suitable
substances, transparent or opaque, upon which can be exhibited notices, advertise-
ments, pictures, designs or inscriptions. Upon the rotation of one or more of the
drums, by either of the means described herein, these endless bands, (with eyelets,
fasteners, or clamps attached thereto, and carrying the cards, glasses or other
suitable substances, with notices, advertisements, designs, pictures or inscriptions
exhibited thereon) are thereby conveyed round the drums; the endless bands may
be utilised to impart movement to some of the drums, where there are a number
of them; consequently during the passage of the endless bands as described, the
notices advertisements, pictures, designs or inscriptions carried on them, will pass
the slots or openings in the panel or panels, hereinbefore referred to, through
which they can be seen or exhibited, and by reason of their movement, will attract
attention to the subject matter so exhibited.
In order that this invention may be better understood and more readily carried
into effect, I will describe the drawings hereunto annexed.
The same numbers refer to the same parts or substitutes therefor in the several
figures.
Fig. 1. is the front elevation of the panel.
Fig. 2. is a sectional side elevation of the panel, also shewing the ends of two
drums with spindles and toothed wheel and pulley attached.
Fig. 3. is a front elevation of part of this machine shewing two drums, their
bearings and part of the endless chain.
Fig. 4 and Fig. 5 are perspective views of parts of the drums shewing method of
construction.
Figs. 6, and 8. shew the method of grouping and arranging the toothed wheels
or pulleys attached to the drums.
Fig. 9. is a detailed view of the drums, endless chain, driving wheel, toothed
motive wheel with endless chain attached thereto, and also the stop lever and spring
in connection therewith.
Fig. 10. is a detailed side elevation of the motive cam wheel and alternative form
of driving wheel with stop lever.
Fig. 11. is a sectional end view of drum shewing electric lamp attachment.
Fig. 12. is a perspective view of the endless band with different method of
attaching cards or tablets thereto.
Fig. 13. is a sectional end view of part of this machine shewing the endless bands
on connection with drums.
In Figures 1 and 2, A is the panel with slots or openings A' and A³ therein.
Behind these openings are the drums B and D mounted or carried on the spindles B¹
and D', B shewing a cylindrical drum and D a polygonal drum. To the
spindle B is firmly fastened the toothed wheel C and to the spindle D' is firmly
fastened the pulley E.
In Figure 3 the vertical standard M has slots cut therein, in which are carried
the shalts F G aud H, which each have one end tapped to receive the screw
nuts F1 F2 G¹ G² and HH2, by which they each are firmly held in their respective
positions on the standard M. The spindle B¹ is hollow and one end fits over and
rotates on the shaft F, the other end rides in a simple slot-bearing in the
standard M. The spindle D' is hollow and one end fits over and rotates on the
shaft H, the other end rides in a slot bearing on the standard M'.
Upon the spindle B' the toothed wheel C gears with the endless chain L (part
of which is shown) which passes over the pulley K. The pulley K is carried on
the shaft G, secured to the standard M.
Upon the spindle D' is shewn the pulley E with serrated edges between its

page_text: flanges, round this pulley an endless chain or endless band of leather or cat-gut
as partly shewn at E³ or other form of flexible connection, can be carried for the
purpose of rotating same when such method is preferred instead of that of the
endless chain L and toothed wheel C.
It will be seen that upon the movement of either the endless chain L or the
endless band E³ the toothed wheel C or the pulley E in gear therewith will
correspondingly move and rotate the spindles B' and D', and consequently the
drums B and D.
The drums may be made of solid wood or metal, or made of segmental parts, or
hollowed out and in Figure 4 a method of constructing the drums is shewn, and it
will be seen that two pieces of metal N and P have been bent as shown and are
fastened back to back at Q and Q¹ by means of rivets, or they may be soldered or
otherwise joined back to back in the same position-these strips of metal are
fastened to the ends of the drum as shewn at R, by a screw being driven through P
into the end of the drum S-this operation is repeated until sufficient strips of
metal have been so placed as to form a complete drum.
In Figure 5 another method of constructing the drums is shewn, and in this case
pieces of metal or wood are formed, as shewn at T, with two grooves, one on each
side, and in the end of the drum S are cut spaces similar to that shewn at S'-into
these spaces the grooved pieces of metal or wood are secured by means of a screw
at Tor the piece T may be either glued, soldered or dovetailed into the space S¹.
This operation is repeated until sufficient grooved pieces of wood or metal to
complete the drum are affixed to the ends thereof.
Between the spaces formed by the edges of the strips of metal as shewn in
Figure 4, or into the grooves shewn in T in Figure 5, there can be inserted cards,
glasses or pieces of celluloid or any other suitable and convenient substance
transparent or opaque as may be desired and upon these can be painted or
otherwise represented any notice, picture inscription or design it is desired to
exhibit. Or there may be pasted upon or otherwise simply affixed to the exterior
of the drums paper, linen, card or any other material suitable for the representation
thereon of any notice, inscription, picture or design, or the surface of the drums
themselves may have such representation painted, or otherwise shewn, thereon.
Upon the rotation of the drums by either of the means described, past the
openings or apertures in the panel fixed in front of them, the representations upon
them will be seen through the said openings and the movement of one or more of
the drums will by the fact of such movement, call or attract attention to the subject
matter represented upon the drums.
In Figure 6 the endless chain L is geared over the toothed wheel or pulley K,
and with the toothed wheels or pulleys CE and E2 (to the spindles of which
drums are fitted) and also geared with the toothed actuating wheel or pulley L², by
which the endless chain L will be actuated.
In Figure 7 the toothed wheels CEE and L2 are geared with intermediary
toothed wheels B³ D' and F³, and the toothed actuating wheel L² will, in this
arrangement, communicate its motion to the drums by means of the intermediary
toothed wheels shewu and the toothed wheels attached to the spindles of the drums ;
the endless chain L shewn in Figure 6 being in such case dispensed with.
In Figure 8 the gearing of the toothed wheel C is direct with the toothed
wheel E without the use of intermediary toothed wheels, and in the case of either
of the toothed wheel E or the toothed wheel C being geared direct with the
toothed actuating wheel, then the movement of the toothed actuating wheel will be
transmitted to the drums, by means of the toothed wheels attached to the spindles
thereof, without the assistance of the eudless chain L (shewn in Fig. 6) and which
is in this arrangement unnecessary and may be dispensed with.
Upon reference to Figure 9, the endless chain L will be seen in gear with the
toothed wheel or pulley K and also with the toothed wbeels CE¹ & E' also in gear
with the toothed wheel shewn by dotted lines at L' carried on the shaft L³. The
shaft L³ is borne on suitable bearings (not. shewn) and also affixed to this shaft

page_text: is the driving wheel X. This driving wheel has two flanges in which are cut
spaces as shewn at X3 and in the rim between the two flanges are cut slots as
shewniby the dotted lines. Into one of these slots it will be seen that the detent W
fits, this detent W is at the extremity of the lever W₁ (referred to herein as
the stop lever) carried on a bearing at W2, and supported by the spring W4 which
hasiits fixing at W. Immediately above this stop lever is a toothed wheel U
mounted on a shaft or spindle at U3, called herein the toothed motive wheel,
round this toothed motive wheel and over another toothed wheel or a pulley V
is carried in gear the endless chain XX, in this endless chain affixed to one of its
linkstis the bult Xand at Xapin is fitted to one of its links which projects on
both sides of the link.
It is apparent that upon moving the toothed motive wheel U in the direction
indicated by the arrow inarked thereon, it will carry with it the endless chain X-X,
with which it is in gear, and in the course of the movement of the endless
chain X X the bolt X2 will, in its passage round, the toothed motive wheel U, come
into contact with the upper edge of the stop lever Wand press it down so 'that
its detent end W will withdraw itself from the slot in the rim of the driving
wheelin which it is shewn, and the driving wheel will be free to rotate when the
pin.X(during the movement of the endless chain XX). comes in contact with the
edge of the space Xtent in the flanges of the driving wheel, and the pin X' will
cause the driving wheel to rotate so far as the course of the pin intersects the
radius of the driving wheel. Again referring to the stop lever it will be seen soon
after the pin X comes into position on the edge of the space X the bolt X will
have been carried so far round the toothed motive wheel that its radius of action
is.no. longer intersected by the upper edge of the stop lever and consequently the
stop lever W by the upward pressure of the spring Wwill have partly resumed
its former position, and as soon as the pin X' has sufficiently rotated the driving
wheel, the slot cut in the rim of the driving wheel next approaching the stop
lever.will come into such a position that the detent W will by the pressure of the
spring W on the stop lever be forced into it and further motion of the driving wheel
will be arrested.
.
In the meantime the actuating wheel 12 fixed on the shaft. L³will have been
rotated to the same extent as the driving wheel X and will thus have communicated
to the endless chain L. the required movement to rotate the toothed wheels C, E
and E, and they will correspondingly rotate any drums that may be affixed to the
spindles upon which the toothed wheels C, E and E² are fastened.
As long as it takes to effect the required number of revolutions of the toothed
motive wheel U to carry the endless chain X.X.once completely round its course,
so long will be the interval between the movements of the driving wheel X, and it
will be seen that by lengthening or shortening the endless chain X X the interval
will be increased or lessened.
Where the movement of the driving wheel is required at short intervals, the
toothed motive wheel U, the endless chain X X (with its pin X and its bolt.X)
and also the toothed wheel or pulley V.may be dispensed with, and in lieu thereof
as shewn in Figure 10, the scam wheel U2, called herein the motive cam wheel, with
cam at X.and pin affixed in its side at X is mounted on a shaft or spindle
at U. The driving, wheel will then be formed as shewn X-it has no flanges like
the driving wheel X in Fig. 9, but in its edges are cut spaces as shewn at .XA,
into one of these spaces the piu X will engage when the motive cam wheel U? is
rotated in the direction shewn by the arrow marked thereon, and as will be seen,
the cam X will in the course of the movement of the motive cam wheel U2 come
into contact with the stop lever W, and press it down so that its detent end W will
withdraw itself from the space in the edge of the driving wheel in which it is
shewn in Fig. 10. By the movement of the cam motive wheel a sufficient distance
the pin X will move the driving wheel X so far as its radius is intersected by
that of the pin affixed to the side of the motive cam wheel U2, and during this
movement the cam X will have been carried beyond the point at which its

page_text: radius is cut by the upper edges of the stop, lever W', and will thus have ceased
to press on the stop lever W, which will be forced upward by the pressure of the
spring Wand its detent. end W. will, engage in the space cut in the edge of the.
driving wheel X which is then, approaching it, as soon as the space reaches a
position immediately apposite to it, the further movement of the driving wheel X
will be arrested until the motive cam wheel, has been, sufficiently rotated, to bring
the cam Xagain into contact with the stop lever, W'.
The movement of the driving wheel X will be communicated by means of the
spindle L³ to the toothed, actuating, wheel, L and consequently by means of the
endless chain 'L to, the.. toothed wheels, C, E and E and the drums, attached to.
the spindles upon which the said toothed wheels CE and E are, fastened.
The pin Xin Figure 10 may be used to transmit the, necessary movement to the
stop lever cl, and the cam X may be utilised to convey the necessary movement to
the driving wheel X6, by its engaging the spaces cut in the edge of: the driving
wheel X. But it is.obvious that in this last arrangement the axes of X" and U2
will be situated in a differentiposition to that in which they are when the movement.
of X is obtained from the action of the pin X³.
In Fig. 11 the collar C³ is loosely mounted on the spindle B and to the collar.
there is affixed at the electric lamp E L; the collar C³ is extended on its lower-
side by an arm upon which is screwed, or otherwise mounted; the weight: C which.
serves to keep the collar, in the same position during the revolution of the.
spindle Bl

In Figure 12, A. X. is a flexible band of leather, or canvas in which a hole has-
been punched and an eyelet: fitted, therein at A. E also at AO through the eyelet
(at AO) a metal paper fastener, is placed which passes through and fastens the
card or tablet A Z to the flexible band.
BW shews. a. metal clamp fastened, to the flexible band at B S by means of a
rivet and the card or tablet, BX is secured by the clamp B W.
BQshews the clamp in another form, with side turned in, in which,the card or-
tablet B Z is placed.
As shewn in Fig. 13-the endless. flexible bands. A.✗ two (or more if necessary).
in number pass over &, partly round the. drum, B B &, also partly round the
drum DD to the.. flexible bands are affixed or attached cards or tablets by
clamps or paper fasteners as described & shewn in Fig. 12. Upon the rotation of
the drum DD by either of the means previously described, the endless flexible. bands
are conveyed round, the drums &, as they pass the openings or, apertures A' & A³
in the panel A the cards, or tablets. are visible, through the said openings & by
their movements attract attention.
Although the drums shewn in Fig. 13 have 4 sides, the drums may be cylindrical
in form if required, or have any other, number of sides that will conveniently meet
the requirements for which the apparatus is constructed.
