FREDERI[C]K PETERSEN and JOHN HENRY RICHARDSON DINSMORE both of
Liverpool, in the county of Lancaster. "IMPROVEMENTS IN AND RELATING TO
COUNTING On CHECKING APPARATUS PART OF WHICH INVENTION IS APPLICABLE
FOR BELLS OR GONGS USED FOR OTHER PURPOSES."
In ordinary counters of the circular description a large size of box in proportion
to the size of figure is required. This obstacle prevents counters of this kind being
used for vehicles when large figures are required. To obviate this and also to in
other respects give a better check and registration and to provent over crowding
beyond the statute limit in ferry steamers and the like the present invention is
designed To show the large figure an endless band arranged to zig-zag between
rollers and with loops one inside the other to economize space is used the flat side
exposed to the glass side of the box so that practically the entire surface of the
side can be utilized for figures. To enable this band to run straight it has cross
stays or bars say one inch apart and a little longer than the band working into
holes or between pegs in wheels or discs at the ends of the rollers or of one of the
rollers over which it runs. We sometimes also put eyelets in the band. On this
band nearly the size of the side of the box the figures are printed in succession.
The largest roller upon which the band runs and which drives the band by its
pegs or grooves locking into the cross pieces of the band is of such diameter that
one revolution of this pulley shall move the band one figure forward. The roller
works loosely on the shaft between the peg wheels which grasp the overhanging
cross pieces. On same spindle is a small loose pinion gearing into a large spur

page_text: wheel which is moved a given distance every time a handle is brought down by
hand or other mechanism which takes place whenever 1 has to be added to the
number as when a passenger goes through the paygate and turns the turnstile or
other mechanisın. The loose pinion has a pawl catching on the peg wheel and
thus as it moves it moves the figure band forward one figure
The handle being pulled down it releases a spring on the large pinion which
brings back the large spur-wheel and with it the pinion. This goes on for nine
revolutions when it will communicate motion at the same time to the second
tens" band by a mechanism of the following description
On the aforesaid spindle is a pinion with fifteen teeth On this is another disc
with one tooth and two hollows geared into an intermediate wheel with in
my experimental arrangement thirty three teeth but any nuber will do. A
thickness of one third is removed froin each side of this wheel for eighteen teeth
and the gearing arranged so that at each revolution of the fifteen tooth pinion the
thirty three tooth wheel will be brought forward two teeth. Half of every
alternate tooth is cut away to a curve to prevent the intermediate wheel from
turning either one way or another except when acted upon by the disc with one
tooth. When the first roller has made nine revolutions eighteen of these teeth
will have moved so that the outside thicknesses are brought out of gear with an
intermediate wheel acting for the pinion of fifteen teeth when an end wheel on the
spindle will be out of gear until another set of nine revolutions have been
performed The roller for the second band works on a tube spindle going straight
through. Over both ends of the first spindle is a cap in which it works, a check
pawl prevents any of these wheels or rollers from turning the wrong way. A
hooked pawl will allow the large spur wheel to rotate in one direction only until
the completion of the stroke of the handle when a projection will act in the lower
part of the paul lifting it up. In this position it will remain while the spring
forces the large spur wheel back to its former position when another projection
will force the pawl to resume its former action.
The arm of a conical toothed segment is also moved by a projection on the large
spur wheel This works into another similar segment fastened on the inside of the
back of the box the release of which strikes a bell. The bell is corrugated in
section. This enables us to place a bell in a small compass yet give probably a
louder and moro distinct ring than an ordinary bell double its weight or diameter:
the curves of bell should have a radius equal to one quarter the width of bell
This gives the loudest and most distinct sound. Attached to the counting
apparatus and in connection with same is an arrangement for registering,
stamping, printing or embossing and perforating tickets. A ribband of paper (in
our experimental apparatus) sixty five feet long by one inch or more in width is
wound on a bobbin and this is placed between brackets The end of the paper
passes in front of discs one on the units roller shaft the others geared to change
their numbers at every entire revolution or ten revolutions or one hundred revolutions
et cetera of this units disc; consecutive numbers are engraved on the periphery
of each namely 1-2---9-0. The strip of paper then passes on between two
small rollers and out through the side of box. The pulling lover being moved a
change of figures will take place on the discs in front of small rollers these again
are revolved half a turn being actuated by a large tooth wheel geared into one of
the roller shafts and this again is geared into the shaft of the other. Each half
revolution will bring a fresh surface of the paper band in front of figures on the
large discs when a projection acting on a second lever will press the top of the
small roller against the paper and the engraved figure behind it, thus embossing or
imprinting a number on the paper.
Another revolution will stamp another while the part stamped with the former
number is passing between the small rollers which will perforate it. From thence it
passes through the side of box as a numbered perforated ticket and can be detached
and given to the passenger as receipt for fare. If desired permanent dies with
printed matter can be fixed alongside the printing discs and thus print on the

page_text: ticket along with the discs The larger lever of this motion may either be acted
on by motion of the large spur-wheel already mentioned or by a separate handle.
This is continued up to, say, one thousand tickets when the paper band will have
run out. Then the top of box can be taken off by aid of tho key and a
new bobbin inserted between the brackets the end of old paper fastened
to new and passed through the side of box by turning the key. The key
is inserted over a pin close to the lower end of a locking lever, by turning it
round it will first release the locking lever thereby unlocking the top of the box
for admission of a new paper. By continuing to turn it round the wings of the
key will act in ratchet wheels each of these having eighteen shallow and one deep
long tooth the key thus acting in a fresh tooth at each half revolution until it
comes to the deep long tooth when all further moving of the wheel is prevented
thus bringing each disc back to zero the key is then removed, the top of box
replaced and kept firm by the top end of the locking lever. It will be seen that
it is impossible to turn the key the wrong way the lower end of lever preventing
it; at each half turn of the perforating rollers an arin with fulcrum is acted on
by these rollers lifting and releasing a hammer which strikes a bell with all its
curves based on the same principle as larger bell Its use is chiefly for ferry
traffic. The number discs are placed side by side with side projecting discs or
sleeves not interfering with cach other at the end of each is fastened a disc of
insulating material thus forming three or more as the case may be concentric
insulating discs on the face of each is drilled ten holes numbered to correspond
to the other numbers on discs. If any desired number is required to be indicated
by an extra ring of bell the little conducting studs are placed in the aforesaid
holes corresponding to the desired number and the discs will continue to go round
until the required number is obtained when the studs will be in line In front of
these studs is the following arrangement two binding screws, a series of springs
insulated from each other, the two outside each in contact with a binding screw
the wires leading from these to a battery and electro-magnet (the latter acting
either on the little bell or releasing a bolt) When the aforesaid studs pass all in
line between their respective springs a complete electric circuit is established
which will actuate the magnet and either ring the bell or stop the turnstile

The whole apparatus may be attached to the ordinary turnstile of ferries.
steamer registered to carry say, seven hundred and ninety five passengers is being
loaded. This number is set on counter according to aforesaid instructions. On
the passing of each passenger through the stile a new number is indicated until
the full complement has passed through, when the electric current is closed, the
electro-magnet acting on a belt or similar arrangement locks the stile and prevents
overcrowding; when the steamer has left the key is inserted and if the next
steamer is of a different capacity its number is set and the discs brought to zero
and thereby releasing the bolt that locks the stile. The key is then removed and
the stile will admit of passage as before. On the engraved discs before mentioned
are in our experimental model ten projections on the concavation of each.
numbers are engraved consecutively. The concavation corresponding with the
curvature of the sinall perforation rollers on each disc is a ratchet wheel with the
eighteen shallow teeth and one deep tooth and between the discs are placed egg
shaped pieces of thin metal the same size as the ratchet wheels at larger end and
hanging below these at the longer end.
The
In summing up as a whole the counter will exhibit a figure of large size will
deliver a ticket for the amount of fares received and will ultimately if so desired
not admit any more than a certain number passing. It may also be used as a
whole or in parts with printing textile, as a counter of games such as billiards,
croquet golf et cetera, for the revolutions of steam engines or similar machinery,
to railway and stations, bicycle or similar conveyances, its size of course
corresponding to the work it has to be used to.

by the said Frederi[c]k Petersen and John Henry Richardson Dinsmore in the
Great Seal Patent Office on the 19th December 1882.
FREDERI[C]K PETERSEN and JOHN HENRY RICHARDSON DINSMORE both of
Liverpool in the county of Lancaster IMPROVEMENTS IN AND RELATING TO
COUNTING OR CHECKING APPARATUS PART OF WHICH INVENTION IS APPLICABLE
FOR BELLS OR GONGS USED FOR OTHER PURPOSES.
In ordinary counters of the circular description a large size of box in proportion
to the size of figure is required. This prevents counters of this kind being used
for vehicles when large figures are required. To obviate this and also to in other
respects give a better check, and registration and to prevent overcrowding beyond
the statute limit in ferry steamers and the like the present invention is designed.

To show the large figures an endless band A is used which takes a zig-zag or
circuitous course over rollers a in a manner similar to that shewn in the diagram
Fig. 4.
The figures on the band are exposed to view at A¹ in the side or front of
the box opposite to which a sheet of glass B is inserted so that practically the
entire surface of the side of the box containing the apparatus can be utilized for
displaying the figures and their size only limited by the size of the apparatus.
To ensure that the band A shall run straight and always advance at each revolution

page_text: of the roller C or D a length corresponding to the size of the figures on it there
are cross stays or bars a' attached to it in length slightly exceeding the width of
the band and say one inch apart. These stays or bars work or fit into notches c―d
in discs or wheels C-D' at the ends of the rollers C and D from which the band A
receives its motion. Of course instead of notches cut in the discs C and D pegs
might be used between which the bars a would fit or a single peg might be used
and eyelet or other similar holes punched or cut in the band but we prefer the
arrangement shown as being the most suitable.
The bands A we prefer to make of double material and between the two
materials before being stuck or fastened together the bars a' are placed at the
proper distance apart. The band is then fastened together as an endless whole and
the figures in succession painted or printed upon it.
The rollers C and D, the circumference of each of which is equal to the exact
length of the figure on the band A or one tenth of the length of the band are loose
on and revolve freely on their axes. The motion of the band A which passes over
the roller C and carries the units figures is conveyed through the spindle E to the
notched discs C' keyed thereon and through them by means of the bars or stays a
to the band. The discs C' are of such a size that at each revolution the band A is
advanced one tenth of its length or the length of one figure. On one end of the
spindle E is keyed or Grmly fixed a small ratchet wheel G which is carried round
when the machine is in operation by a pawl g. The pawl g is carried on a small
pinion wheel G' which revolves loosely on the end of the spindle E or on a boss
on the ratchet wheel C. The wheel G¹ receives motion from a toothed segment or
wheel which is operated by a handle I attached to it by a chain has shewn.
At each pull of the handle to its full length the wheel G makes one complete
revolution carrying with it the pawl and wheel G which latter being keyed to the
spindle E carries round the discs C and advances the band carrying the units
When
figures one tenth of its length or carries it on from one figure to the next.
the handle 1 is released it is returned to its normal position by a spring placed on
its shank or on the spindle of the wheel G but as it is quite obvious how such a
spring might be arranged it is not shown on the drawings. Also the wheel Gu
may be prevented returning to its normal position in the middle of a stroke or
while the figures on the band are not exactly opposite the glass plate, by a pawl
working into it which when the stroke is completed is raised and held up by a
spring until the handle is again pulled when the pawl is again dropped into tho
teeth.
The band carrying the tens figures is carried round in a similar manner to that
carrying the units figures by means of stays a fitting into notches d in the
discs D. The roller D revolving loosely on the sleeve F to which the discs D' are
keyed or securely fixed. The motion to the sleeve F is conveyed by spar wheels I
and J keyed respectively to the spindle E and sleeve F through a carrier wheel K.
To the spindle E is keyed a pinion I preferably with 22 teeth and to the
sleeve F a similar pinion Jwith the exception that one tooth on the pinion J is
filed away leaving a space in its stead. One of the teeth i of the wheel I projects
at one side forming as it were or rather giving the motion of a star wheel with
only one tooth and keyed to the spindle E in close proximity to the tooth i is a
disc L with a notch cut in its circumference. The carrier wheel K which revolves
on a stud screwed or bolted to the frame-work of the apparatus is as shown in
Fig. 5 made up of several segmental pieces screwed or bolted together. The
section K of the carrier wheel which comes opposite to the wheel J is provided
with 20 teeth on a part of its circumference and the remaining part is without
teeth and corresponds with the pitch line of the said 20 teeth. The section K" of
the carrier wheel which comes opposite to the wheel I is provided with 21 teeth
which with the exception of the odd tooth are placed so as to exactly correspond
with the teeth on the section K and the remaining part of the circumference of
this section corresponds with a circle drawn round at the base of the teeth. The
teeth on these two sections of the wheel K are of the same pitch as those of the

page_text: pinions I and J and at intervals gear into them. Two segments and ¹ each
containing 10 teeth are screwed or bolted to the wheel K the teeth on ¹ being
placed so as to come equidistant between the teeth on . The teeth on one of
these segments are actuated by or come in contact with the tooth i on the side of
wheel I at each revolution of that wheel and the teeth on k¹ pass into the notch
at the same time. Thus at each revolution of the pinion I that is at each
revolution of the units roller C the carrier wheel K is moved on the distance of
one tooth of the segments & and k' and when in this way the nine teeth on these
segments have been moved the pinion I gears into the teeth on K" and the
section K being securely attached to K" the teeth thereon gearing into the pinion J
carry it round one revolution and with it the tens roller D.
When this revolution of the pinion J is passed the smooth part of the circum-
ference of the height of the pitch line passes into the space left by the filing away
of the tooth previously referred to and prevents any motion of the pinion J until
the teeth again come round into gear. The carrier wheel K is prevented moving
when not in gear with the pinion I or in contact with the tooth i by means of tho
disc L pressing between the teeth of the segment the wheel being only allowed
to move when the tooth on this segment enters the notch l. When the wheel K
is in gear with the pinions I and J of course the segments k and k' are turned
away and altogether out of gear.
The wheels and rollers herein shown and described are only arranged to display
a number under a hundred but it will be readily understood by any person
accustomed to machines of this description, that by adding another roller similarly
mounted and another set of wheels which will bear the same relation to the
wheels connected with the tens figures that those as to the ones connected with
the units figures the machine inay register and record up to hundreds and so on.
At each end of the spindle E is placed a cap M and M' which cover the wheels
and pinions and keep them in their place.
N is a conical toothed segment pivoted in any suitable position in the inside of
the box of the apparatus. A similar segment N' Fig. 6 is pivoted on the inside
of the back of the box into which N is geared. The pin n on the side of the
wheel G" comes in contact with the projecting arm of N as the wheel revolves in
one direction which on being released N is drawn back by a spring and strikes
and rings the bell O. The arm of N being hinged or pivoted at m the pin n returns
with the wheel without moving N merely pushing the pivoted portion of the arm
out of the way. This is then returned to its normal position by a slight steel
spring pressing against it.
In order to get a bell that while being capable of being placed in a small
compass or confined space will yet give a loud and distinct ring we have designed
a bell of corrugated section which we have found to give a ring probably louder
and more distinct than any ordinary bell of double its weight or diameter. The
curves which we have yet found most advantageous for the bell should have a
radius equal to one quarter of the width of the bell. At O in Figs. 6 and 11 are
shewn bells made according to our design.
In figs. 7 8 9 on sheet 2 are shewn a modified arrangement of part of our
invention. In Fig. 7, two bands are used each passing over separate driving rollers
which are geared together at one end the object being to display the same figure at
two sides of the apparatus at the same time. The bell may be placed in between
the endless bands. In this case the figures are not equal in size to the side of the
box but a glass is let into the side of sufficient size to shew the figures used.
We find that for long bands textile material is not sufficiently strong to bear
the strain to which it is subjected and we make metallic bands made of pieces of
sheet copper brass or other metal hinged or jointed together and when these are
used make the rollers of hexagonal or other angular form the number of sides to
the roller corresponding with the number of pieces in each figure on the band so
that at each revolution of the roller the band will as in the case already described
travel the length of one figure. The pin in the hinge forms the stays and the end

page_text: projecting at each side fits into notches made in the angles of the driving discs at
the end of the rollers. Or the pin may not project and the flat rectangular pieces
forming the stays, in the latter case it is necessary that the side discs should be
fast to the hexagonal or polygonal or other rollers employed so as to impart the
motion to the band.
In Figs 7 and 8 are shewn a modified arrangement of operating the rollers the
handle II is attached to the spindle which operates the units figures and at each
revolution the band is moved to the extent of one figure. The pawl h¹ in tho
ratchet wheel prevents any motion in the reverse direction. As the handle is
turned the pin at the end of the lever h² moves round in the groove v and as it
comes to the opening b¹ the handle is prevented being turned further until the pin
is pushed back into the groove by the the knob or pusher H³.
In Figs. 10, 11, and 12 on sheet 3 of the drawings are shown that part of our
invention which refers to the marking or embossing of paper for tickets with the
consecutive numbers of the passengers or persons who have been registered. It
may be used in conjunction with the previous part for displaying the numbers, or
in a separate machine worked by itself. It is in this latter way we have shown it
as being the most easy of explanation.
A ribband of paper of from one to two inches in width and of any convenient or
suitable length (say 60 feet) is wound upon a bobbin P placed between two
brackets P fixed to the sides or top of the box. The paper from the bobbin P
passes between two rollers which hold it while being impressed or marked with
the figures and deliver it with the number registered upon it. Q, Q1, Q", are the
discs which carry the numbers and they are each of the shape shewn in Fig. 17.
Attached to or forming part of each of the discs is a ratchet wheel with 19 teeth.
A space is found between the 19th and the 1st tooth equal to nearly double the
space between either of the other teeth and proportionately deep. The discs are
moved by a pawl r on a lever R. The pawl has three fingers of unequal length.
At each stroke of the lever R the long finger of the pawl moves on the units disc Q
the distance of two teeth on the ratchet and one figure on the periphery and at
cach revolution of the disc Q the long finger falls into the wide space between the
last and first tooth of the ratchet and thus allows the second finger of the ratchet
to come into play and move the tens disc Q' the distance of one figure. When the
tens disc Q has completed a revolution a similar space between the teeth in the
ratchet allows the third finger on the pawl to move the hundreds disc Q¹.
Another dise could be added if it were required to register thousands. A second
set of pawls gearing into the ratchet of each disc prevents any return motion in
the discs. The lever R receives a reciprocating motion from a pin or cam
attached to the wheel S which at every half revolution of the handle S¹ moves the
lever the required distance. The rollers pare carried in a bracket p¹ pivoted to
the side of the box and at each revolution of the wheel S the projection 8 on its
periphery comes in contact with the arm or lever pl and forces one of the rollers p
against the figures on the discs Q and the paper from the bobbin passing between
receives the impression from the figures. The rollers p rotate half a revolution at
each operation being actuated by a spur wheel q. which moves with the units
disc Q and they are geared together by two other wheels keyed to their own axis.
On one of the rollers p is a barbed or tooth rib p³ which fits into a corresponding
indentation on the other roller at each half revolution the effect of these being to
perforate the paper so that it is more easily torn asunder another projection on
the top roller p or on the side of the wheel which is geared to it depresses the
lever of the bainier O' and rings the bell O for each ticket delivered.
In addition to the dies on the discs Q a permanent die similar to that shewn in
Fig. 18 may be attached to the frame supporting the dies on which may be
engraved the amount of the fare required or any other information which it is
desired to put on each ticket.
The lid of the box is held in position by a locking lever T held in position by a

page_text: spring placed at one side of the box, and by two small catches T' placed at the
other side. When it is necessary to remove the lid to renew the roll of paper or
for other cause a key similar to that shewn in Fig. 16 is used. The key is
inserted over a pin t close to the lower end of the lever T and by turning it round
the lever T is released froin its catch in the lid of the box which may then be
removed. This key is also used for resetting the numbered discs and returning
them all to zero. When it is inserted the wings t¹ will take the part indicated by
the circle in dots coming in contact with the teeth of the ratchet wheels attached
to the discs and as each wheel is returned to zero the wing of the key comes into
the wide space in the ratchet wheels previously referred to and described and
ceases to act so that in whatever relative position the discs inay be the turning of
the key will place them all in zero and cease to act on cach when it assumes that
position. It will be impossible to turn the key in the wrong direction as the
wings coming in contact with the lower end of the lever T would be prevented
going further.
The machines shewn in the drawings is operated by a handle at the will of the
person in charge say when a passenger enters a tramcar, omnibus or other public
conveyance but may also be operated if suitably connected at each turn of a
turnstile shewing the number of persons who may have passed through, or
connected to indicator with the large figure and working in conjunction with it.
For use in ferry or other traffic where it is desirable that a specified number of
passengers only should be allowed to pass within a given time we arrange in
conjunction with an electro magnet a bolt or suitable apparatus of any known
construction to prevent the further turning of the turnstile when the current of
electricity is passing through the magnet and arrange our counting apparatus so
that when the specified number are registered electrical communication with the
magnet shall be established. We shew no means in the drawings for fastening or
bolting the turnstile as we make no claim for such but only shew the means we
adopt for establishing the electrical communication when the specified number is
reached.
To cach of the discs Q, Q, Q, carrying the figures is attached a projecting
sleeve and to each of these is fastened a disc or ring of insulating material U, U¹, U
Fig. 13.
In the face of each of these is drilled ten holes each numbered with
figures corresponding with those on the periphery of the discs Q, Q, Q. A
metallic pin fits into one hole in each disc. The pin is placed into the hole in each
disc corresponding with the units tens or hundreds figures respectively of the
specified number at which electrical communication is required to be established
with a locking or other device for stopping the passage or giving a signal or other
purpose. A contact maker similar to that shewn in Fig. 15 is placed in proximity
in front of the discs U carrying the metallic pins. A current of electricity passes
through the wires attached to the binding screws V, VI, as soon as the contact is
complete at the other side of the screws. The parts v. v. v. v. are each insulated
one from the other and it is not until the projecting points of each are brought
into electrical contact at one and the same time that the circuit is complete. As
the discs revolve the metallic pins pass between the points at the spaces w. w. w11.
and when the specified number is reached the three metallic pins stand in a row
between the points of the contact maker and the circuit is complete.
In summing up as a whole the counter will exhibit a figure of large size will
deliver a ticket for the amount of fares received and will ultimately if so desired
not admit any more than a certain number passing. It may also be used as a
whole or in parts with printing and textile machines as a counter of games such
as billiards, croquet, Golf etcetera for counting the revolutions of steam engines
or similar machinery bicycle or similar conveyances its size of course corresponding
to the work it has to be used to.
Having now described our invention and the best modes known to us of
carrying it into effect we wish it to be understood that what we believe to be

page_text: new and desire to protect under the hereinbefore in part recited Letters Patent
is:
1st In a counting or checking apparatus the use of an endless band for displaying
the numbers moved on at each revolution or part of revolution of the driving
roller from one figure to the next and prevented from slipping by a number of
cross stays fitting into notches or their mechanical equivalent substantially as and
for the purposes described.
2nd The means for transmitting motion from one roller or shaft to another
when the first has made a specified number of revolutions wherein the motion is
conveyed from a pinion on the first shaft through a seginental carrier wheel to
the pinion on the second shaft and the segmental carrier prevented from moving
more than one tooth during the intermediate revolutions of the first shaft by a
disc with notch therein working in connection with a second series of teeth on the
carrier substantially as described and shewn in Figs. 2 and 5.
3rd The construction of a bell corrugated or in curves of radius equal to about
one quarter of its width substantially as described and shewn.
4th In a counting or checking apparatus the construction of the discs for
carrying the figures with a ratchet wheel attached by means of which the discs
are moved forward by a pawl working therein and returned to zero by a key that
fits into the same substantially as described and shewn.
5th The combination with a counting or checking machine of apparatus for
establishing electrical communication or completing an electric circuit when a
specified number has been reached in which a series of metallic pins or other
conductors in connection with though insulated from the discs which carry the
figures complete the circuit when the total number of the pins are in contact at
one and the same time with the points of a series of wires or springs which are
insulated from each other, substantially as described and shewn.
6th The general arrangement and construction of counting or checking apparatus
herein described and shewn when taken as a whole and the special apparatus
for displaying large sized numbers shewn in figs. 1. 2. 3. 4 and that shewn in
figs. 10. 11. 12 taken separately.
In witness whercof I the said Frederi[e]k Petersen for and on behalf of
myself and the said John Henry Richardson Dinsmore, have hereunto set
