PROVISIONAL SPECIFICATION left by the said William Maberly Llewellin
at the Office of the Commissioners of Patents on the 30th September 1882.
WILLIAM MABERLY LLEWELLIN of Bristol in the County of Gloucester and of
Glasgow in the County of Lanark, North Britain, Engineer, "IMPROVEMENTS IN
APPARATUS FOR CHECKING OR INDICATING THE PERIODICAL ARRIVAL AND DEPARTURE
OF EMPLOYEES AND IN CLOCKWORK MECHANISM FOR ACTUATING PARTS OF SUCH
APPARATUS."
"
This Invention, which relates to apparatus for checking or indicating the
periodical arrival and departure of employees and to clockwork mechanism for
actuating the moving parts of certain arrangements of such apparatus, is a further
development of the Invention for which Letters Patent were granted to the
present applicant bearing date the 7th day of June A.D. 1881 Number 2472.
One improvement consists in providing the checking apparatus with a shoot or
sboots so projecting that employees leaving or entering the place of their employ-
ment by another apartment or on the other side of a wall or partition from that
at which the apparatus is situated may pass their checks into the machine.
In apparatus of that class for which Letters Patent were granted to John Adams
bearing date the 11th day July A.D. 1855 Number 1554 and wherein the shoot
rotates over a stationary box for holding the checks, in lieu of supporting the
spindle on the box itself, an improvement consists in introducing a bridge extending
across the top of the box on which bridge the lower end of the spindle is stepped
thereby enabling the box to be withdrawn at pleasure.
:

page_text: .
Another improvement consists in inclining the bottom of the check box in order
to cause the checks deposited in its several compartments to roll towards the
circumference and in cases where the check boxes rotate and where it is desired to
have checks taken at a number of times during the day. A further improvement
consists in hinging the bottom and securing it by a catch which coming in contact
with a fixed key releases the bottom and allows the checks to drop down into
another and lower compartment.
Another improvement consists in the employment of a tier of two or more
check boxes so arranged that the superposed boxes shall each have one open
bottomed compartment corresponding and communicating with the lowermost box
which alone rotates and thus receives into its several compartments the checks
passed into the superposed boxes. So soon as all the compartments in the lower-
most box shall, in rotation have been brought under the false divisions of the
superposed boxes the said under box is disconnected from the actuating mechanism
and remains stationary whilst the box immediately above is connected and
Fevolving receives the checks into its several compartments in the same manner
and so on until the uppermost box in the tier is reached. By this means provision
may be made for taking checks during two or more days without removing the
boxes from the apparatus. To facilitate the removal of the boxes they may be
made in halves or built up in segments or in the form of a segment of a circle.
Another improved arrangement of the mechanism consists of a drum or pulley
over which is passed an endless band or chain of steel, iron or equivalent flexible
material and in the band projecting points are formed or fixed or a slot or
elongated hole is cut..
.
The other part of the arrangement consists of a hopper for placing the checks in,
at the bottom of which is an elongated shoot or funnel down which the checks can
fall.
This funnel or shoot is divided into as many divisions as there are times to be
checked these divisions being made by movable trap doors or diaphragms which
move on pivots, hinges or an equivalent arrangement and are actuated by levers
projecting through the side of the funnel. The trap doors or diaphragms are
arranged to close obliquely in the funnel or shoot.
At the side of the shoots immediately above the trap door when it is closed,
across the shoot is an opening in the side of the funnel and fitted to this opening
is another funnel or shoot.
The action of this arrangement is as follows:-The endless band having motion
given to it from the clock, at certain times the projecting points in the band or the
slot liberate the lever projecting through the side of the funnel and the diaphragm
or trap door falls across the funnel in an oblique position causing any checks that
may fall down the funnel to be stopped and diverted into the side shoot and thence
into a drawer or box-As the band moves on to shut another diaphragm or trap-
door another following projection in the band opens the trap-door that had
previously been closed. The distances between the levers and the respective trap-
doors correspond to various intervals of time.
A combination of several of these arrangements may be made by which one clock
can give motion to two or more endless bands placed in suitable casings separate
and distinct from one another.
Under another arrangement the check boxes are stationary and represent certain
times and a hopper or shoot or a series of hoppers or shoots is fitted to the endless
travelling band so as to deliver the checks into the said boxes.
In all arrangements by means of endless bands two or more bands may be used
or any combination of bands.
In order as far as possible to detect any attempt of one person passing in the
checks of another at the same time as or immediately after his own the openings
through which the checks are passed into the machine are or may be covered at
the inside by a spring or springs which is or are pushed back in passing in a check
and thereafter again immediately closes or close the opening..

page_text: To classify the checks of employees pursuing different avocations a series of boxes
or of compartments in a box is used into which the checks of the different classes of
employees are passed through separate shoots these shoots being all rotated
simultaneously from the same clock.
Another improvement consists in so arranging the check boxes that the checks
passed thereinto at a time when a number of persons are entering or leaving the
work during the day shall pass into one series of compartments whilst those passed
into the machine when only few are so entering or leaving shall pass into another
series of compartments. This is effected by dividing the box circumferentially into
a series of rings these rings being again divided into a series of compartments.
Over these compartments stationary shoots are arranged into which the checks are
delivered from the rotating shoot and directed into the proper compartments of
the box.
In order to provide for the reception of a larger number of checks than one
compartment of the box can conveniently contain another box or a box divided
horizontally by a diaphragm is arranged underneath. The compartments of the
superposed box into which the large number of cheeks would fall is made without
a bottom so that the checks may drop through it into the box or space underneath
which is without compartments or has fewer and consequently larger compartments
in it.
:
With reference to the apparatus described in the specification filed in pursuance
of the aforesaid Letters Patent granted to me for checking the periodical arrival'
and departure of managers foremen and others in charge an improvement consists
in coiling the roll of paper on a drum attached to a spindle revolving in a vertical.
horizontal or inclined plane and which spindle has also another drum fixed on it as
and for the purpose hereinafter set forth. From the first drum the paper passes
over another drum secured on the actuating spindle of the apparatus and from
thence it is passed partially round a third drum in the circumference of which*
spikes or pins are fixed for the purpose of marking the paper and also of assisting:
in pulling it round. The last mentioned drum is placed near the aperture in the
casing through which the foremen and others sign their names and it is geared
with and receives motion from the actuating spindle by toothed or friction wheels
or their equivalents. The paper after passing round the spiked drum may either
fall into a space below or it may be coiled on the second drum on the first
mentioned spindle.
Guide or couch rollers covered with felt or equivalent material are also provided
in conjunction with the spiked drum in order to conduct the paper to and from the
said drum and to afford a resisting medium to the spikes in entering the paper.
Under another arrangement the paper may be presented in proper position for
signing by an escapement motion fitted to a spindle which rotates the shoot and
which consists of a disc with a series of pins in its periphery, these pins at certain
times act upon one end of a lever the other end of which has a pin in it which enters
holes or recesses in a drum which has spikes in its circumference to draw the paper
into position. On this drum and on another drum underneath opposite ends of a
cord are attached the cord passing over and under rollers to a weight which is
hung upon it. An endless band is also provided fitted with pins for perforating
the paper so as to indicate the time at which a signature is made.
Another alternative arrangement for this part of the apparatus consists in
winding the paper on a drum and thence passing it over a larger drum operated by
the actuating spindle. Upon leaving the second drum the paper is coiled on a third'
drum which by means of a weight, spring or their equivalent exercises a tension
upon it. The larger or second drum is set with pins or teeth to draw the paper in
the required direction and the said pins may perforate the paper and indicate the
times when it is exposed for signature.
Under another arrangement a flat piece of paper ruled off into divisions
corresponding to different periods of time may be used to check the arrival and
}

page_text: departure of the foremen and others in charge the said piece of paper being
secured on a rectangular board and reciprocated by the clock work so as to bring
the various divisions in one line or row opposite the signing orifice during the day.
At the end of each day or other period of time the board (which is removable at
pleasure) is raised or lowered so as to bring another series of division's into position
for being signed on. Instead of paper the board itself may be made of slate
papier Maché or equivalent material.
.
Under another mode the paper for signature is fitted to a horizontal table fixed
to and rotating with the shoot. An opening is made in the top of the casing
containing the box which opening is provided with a shutter, capable of being
shifted to a greater or less distance from the centre of the apparatus so as to enable
signatures to be made in concentric rings around the paper. This shutter may be
actuated by a worm screw or by equivalent means.
Another part of this Invention relates to the "Check boards" described in my
said previous Specification.
The board or boards in one modification are placed horizontally and are each
provided with a pulley. Between each board another pulley is placed and a cord or
chain attached to a counterweight passes alternately, over and under these pulleys.
At the other end each board is provided with a catch and bolt or its equivalent
which is operated by a rack and ratchet wheel which wheel may be on the spindle
of the clock or on an independent spindle connected to the clock. At certain
times the rack and wheel release one, bolt and the check board held by that bolt is
then drawn forward by the action of the counterweight. Instead of being
horizontal this arrangement may be placed vertically or in any inclined position
Another part of this Invention relates to improvements in the Clockwork
mechanisin by which the moving parts of certain arrangements of the apparatus
are actuated and it consists in the employment of a barrel similar to the barrel
of a musical box and which turns round once in each hour, being geared with the
going part of the clock. The barrel is divided circumferentially and equally
into 12, 24 or any other desired multiple of these spaces. In the division lines
projecting pins are placed corresponding to certain times in each hour.
13.
·
In conjunction with the pins on the barrel a lever is employed and which is
connected to a collar and disc sliding in guide rods one side of the disc being
connected by a chain or its equivalent to a lever the other side being similarly
connected to a counterweight. The lever to which the chain is connected is
provided with a spring having a pin fixed therein and which passes through a bole
in the lever so as to acted on by the stepped periphery of a cam or "snail" geared
to the hour, hand of the clock. In conjunction with the spring another lever, is
provided which at certain times in the day is acted on by the said spring by
which it is caused to bring the lever which acts on the pins on the barrel back to
position for beginning another day's work. At each time that the sliding lever is
lifted by a pin on the barrel the hopper or shoot or the rotating box or their
equivalent is operated so as to bring another compartment into position for
receiving the checks and the said turning is effected by a spindle which is geared.
by a combination of wheels to a drum actuated by a spring the said drum being
also geared by wheels, cams and levers to the lever acting on the pins of the
barrel.
a
1
'
Under, another arrangement of the clock in which the barrel with pins is
dispensed with a ratchet wheel or snail", is employed in lieu thereof. This
wheel is centred on a stud and geared with the hour hand of the clock and it has
teeth only on certain parts of its periphery. These teeth gear with a pawl formed
or attached to a lever which has also another, pawl on it the latter pawl being
at certain times acted on by pins fixed around the periphery of a disc centred on
the minute hand of the clock and geared with the ratchet wheel by a train of
wheels. The pawl lever at certain times acts on another lever the effect of which
is that a drum or cylinder to which a spring is connected is set in motion and the
on

page_text: said drum or cylinder through the action of a train of wheels turns the shoot or
rotating box or their equivalent sufficiently round to deliver the checks into
another compartment or division.
An alternative method consists in dispensing with the barrel and substituting
a chain or other flexible equivalent but preferably a chain with 720 or other
convenient number of links. Each link corresponds to a minute or other period
of time and has two holes and in the link corresponding to a certain minute in
each hour a projecting pin is placed which coming against raises the discharging
lever and so actuates the registering arrangement.
"
Another alternative arrangement consists in substituting a screw with 24 or
other number of threads in lieu of the barrel. Projecting pins are placed either on
the top or bottom of the thread thus doing away with the "snail".
Two three or more checking machines and series of check boards may be actuated
from one clock by means of an endless band, connecting rods, cranks, 'or eccentrics
or a combination of any or all of them.
"
The doors for affording access to the interior of the apparatus are, instead of
being hinged as formerly, preferably made to slide in grooves.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said William Maberly Llewellin in the Great Seal Patent Office.on the.
30th March 1883.
WILLIAM MABERLY LLEWELLIN of Bristol in the County of Gloucester, and of
Glasgow in the County of Lanark, North Britain, Engineer IMPROVEMENTS IN
APPARATUS FOR CHECKING OR INDICATING THE PERIODICAL ARRIVAL AND DEPARTURE
OF EMPLOYEES AND IN CLOCKWORK MECHANISM FOR ACTUATING PARTS OF SUCH
APPARATUS.
:
My said Invention, which relates to apparatus for checking or indicating the
periodical arrival and if desired also the periodical departure of employees and to
clock work mechanisin for actuating the moving parts of such apparatus is a further
development of the Invention for which Letters Patent have been granted to me
bearing date the 7th day of June 1881 N° 2472.
And in order that the Improvements constituting my present Invention may
be properly understood I have hereunto appended four sheets of explanatory
drawings with reference to which I now proceed more particularly to describe the
said Invention and the system, mode or manner in, or under which it is or may be
used or carried out in practice.
One improvement illustrated in side elevation at figure 1 and in plan at
figure 2 sheet 1 of the drawings, consists in providing the checking apparatus,
constructed in accordance with my said previously patented Invention with a shoot
or shoots a, so projecting that employees entering or leaving departments of the
place of their occupation by doors or gates at opposite sides of a wall or walls from
that at which the apparatus is situated may be all enabled to pass their checks
into one machine.
The shoot or shoots a, which may be of any desired shape, have each a series
of slits at the end b, through which the employees checks are passed into the shoot
and from thence together with the checks passed in through the slits c they pass
into the rotating shoot described in the specification filed in pursuance of my said
previous patent and are thereby delivered into that one of the several compart-
ments of the check box or tray which corresponds to the time at which the
employee arrived or departed. Under this, as under the previous Invention the
slits at b and c may be, at certain times, closed so as to prevent the admission of
checks, by a shutter or plate which is or may be locked in position.
In apparatus of that class for which Letters Patent were granted to John Adams
bearing date the 11th day of July A.D. 1855 N° 1554, and wherein the delivering
shoot rotates over a stationary box for receiving the checks, instead of supporting
the spindle by which the shoot is rotated on the box itself as under the said
Invention an improvement illustrated at figure 3 sheet 1 of the annexed drawings
consists in introducing a bridge a, extending from side to side of the casing b,
across and above the upper edge of the box c, and in stepping and supporting the
lower end of the spindle d, of the rotating shoot e, the said bridge thereby enabling
the check box c, to be withdrawn at pleasure through a doorway in the side of the
casing b, without having first to open the top of the casing and remove the shoot e,
and apparatus connected with it as under Adams' said patent. The bridge is
bevilled to a point at its upper edge as shewn at figure 4, to prevent the checks
resting on it.
Another improvement consists in inclining the bottom of the check box so as to
cause the checks deposited in its several compartments to roll or slide towards the
circumference or widest part of each compartment.

page_text: In cases where the check boxes rotate an improvement illustrated at figures 5
and 6 sheet 1 of the drawings consists in hinging the bottom a of each compart-
ment of the rotating box and securing it by a spring or other equivalent catch b
which catch as the box rotates coming in contact with a key or rod c fixed in the
outer casing d, is thrown or drawn back thereby releasing the bottom and allowing
the checks to drop down into the corresponding compartment of another box
underneath and which is or may be stationary After having so delivered the
checks the bottom of the compartment as the box continues to rotate comes in
contact with the next key or rod c. of the series by which it is again closed up.
Another improvement illustrated at figure 7 sheet 1 of the drawings consists
in the employment of a tier of two or more check boxes communicating with each
other. On the figure three such boxes are shewn and they are so arranged that
the superposed boxes a, and b. have each one open bottomed compartment c,
corresponding to and communicating with the lowermost box d. all the boxes are
in succession rotated beginning with the lowermost box d, which, while rotating,
alone receives the checks into its several compartments through the open bottomed
compartments c, of the boxes a and b.
So soon as all the compartments in the lowermost box d, shall in rotation have
been brought under the open bottomed compartments c, the said box d, is dis-
connected from the spindle e (which is rotated by the clock work) and remains
stationary whilst the box 6 immediately above is connected to the spindle e, and
being thereby rotated receives the checks into its several close bottomed compart-
ments, through the open bottomed compartment c of the superposed box a, and
so on.
As shewn on the figure the several boxes are in rotation connected to the
spindle e by a block or collar f. sliding on a feather or slot in the spindle e and
having vertical motion communicated to it at the required times by the clock to
which the said block is connected by a chain, cord or equivalent means, the said
connection being preferably at the interior of the spindle e, or alternatively the
block may be adjusted by hand.
By means of this arrangement provision may be made for taking checks during
two or more days without removing the check boxes from the apparatus in the
interval. To facilitate the removal of the boxes they are or may be made in
halves or built up of segments connected together when in position or they may
be in the form of a segment of a circle that is to say having a slot or space
extending from the centre to the circumference to enable them to be placed on and
withdrawn from the spindle e. Another improved arrangement of the apparatus is
illlustrated at figures 8 and 9 sheet 1 of the drawings and it consists of drums or
pulleys a, b over which is passed an endless band or chain c, of iron, steel or
equivalent flexible material. In the band slots are cut as indicated at d, figure 9.
The other parts of the arrangement consist of a vertical hopper e, having slots in
its upper end to pass the checks through. The hopper communicates with a
vertical shoot or funnel f, divided into as many parts as there are times to be
checked during a day or other period of time. These parts or divisions are made
by movable trap doors g hinged at one side of the hopper so as to close
obliquely and they are actuated by levers h, which are preferably situated outside
the funnel and connected to the pins or journals around which the trap doors turn.
In the shoot or funnel f, and in line with the trap doors when in their raised or
closed position; openings or side shoots i, are made or fitted and these project over
boxes trays or drawers k.
The action of this arrangement is as follows:-The endless band or chain c,
having motion given to it from the clock at certain times (these being the times
at which a check is required to be made) one of the slots d, in the band coines.
opposite the weighted end of one lever h, and the lever then falls thereby raising
the trap door across the funnel into the position shewn at ✗, and causing the
checks to be directed into the box drawer or tray provided in conjunction with
that door. As the band c, moves on in the direction of the arrow the weighted

page_text: end of the previously depressed lever h, is raised and prevented from again falling
by a solid part of the band being opposite to it and another slot coming opposite
the weighted end of the next lever h, the following trap door in the series is closed
across the funnel f.
'
1
Instead of slots pins may be inserted in the band to act on the levers or other
equivalent arrangements of mechanism may be used.
The entire apparatus is enclosed in a suitable casing.
Under another arrangement: a hopper or shoot or a series of hoppers or shoots
is or are fitted to the endless travelling band so as to deliver checks into the
boxes, trays or drawers k, which drawers in this case also represent certain periods
of time.
Under either of the arrangements in which an endless travelling band is used as
herein before described a combination of several sets of the apparatus may be made
by which one clock can give motion to two or more endless bands placed in casings
separate and distinct from one another.
In order as far as possible to detect any attempt by one person to pass in the
checks of another at or immediately after or before his own the openings or Blits
through which the checks are dropped into the machine are or may be covered.or
contracted at the inside by a spring or springs as indicated at a, figure 10, sheet 1
of the drawings. In passing in a check the spring is pushed back and thereafter
again immediately closes or contracts the opening or slit, so that should a person
attempt to drop in two checks following he would occupy such an amount of time
in passing the machine as would tend to attract attention to his act.
In order to provide for the classification of the checks of employees pursuing
different avocations in the same work or factory a series of shoots are used as
illustrated at a, b, c figure 11 sheet 1 of the drawings.
These shoots are all mounted on the same spindle d, and are rotated simul-
taneously from one clock and the checks are passed into them through separate
sets of slits one such set being provided for each shoot.
The shoots a, b, and c, each deliver the checks passed through it into a separate
and distinct box or tray or as shewn at figure 12 sheet 1 the compartments in one
box or tray may be divided by concentric divisions e into a series the shoot a,
delivering into the inner the shoot b, into the middle and the shoot c, into the
outer series of compartments.
By this arrangement a large number of different cla-sifications may be obtained
by simply providing a rotating shoot and a separate box or series of compartments
in a box for each classification.
.
The shoots instead of passing through each other as shewn at figure 11 may be
mounted on the spindle d, one below the other.
Another improvement illustrated at figure 13, sheet 1 of the drawings consists
in so arranging the check boxes that the checks passed thereinto at a busy time.or
when a number of persons are entering or leaving the works shall pass into one
series of compartiments whilst the checks passed into the machine at a slack time
or when comparatively few are so entering or leaving shall pass into another
series of compartments. This is effected by dividing the check box circumferentially
into a series of rings these rings being again divided into a series of compartments
as before described with reference to figure 12. Over these compartments
stationary shoots a, fixed around the interior of the casing b, are arranged into
which the checks are delivered from the rotating shoot c, and directed into the
proper compartments of the check box or tray.
In order to provide for the reception of a larger number of checks than one
compartment of the check box can contain without making the box of inconvenient
dimensions the box is divided by a horizontal diaphragm as seen at a, figure 14
sheet 1 into two parts The upper part is divided into the required number of
compartments for the reception of the checks at different times during a day and
that or those compartment or compartments into which the large number of checks
would fall is or are made without a bottom as indicated by the black space at
.

page_text: figure 15, so that the checks may drop through it or them into the box or space
beneath which is without compartments or has fewer and consequently larger
compartments in it.
This method of dividing the check box into an upper and under part is also
shewn on the plan figure 12 as used in conjunction with the arrangement for
classifying the checks.
With reference to the apparatus for checking the periodical arrival and departure
of managers foremen and others in charge described in the specification filed in
pursuance of my aforesaid Letters Patent an improvement illustrated at figures
16, and 17, sheet 1 of the drawings consists in coiling the roll of paper on a drum a,
fixed on a spindle supported in brackets b, secured to the casing c. From the
drum a, the paper passes over another drum d, secured on the spindle e, actuated
by the clock and from thence it passes partially round a third drum f, in the
circumference of which spikes or pins are fixed for the purpose of marking the
paper and also for the purpose of assisting in pulling it round. The drum f is
placed near the aperture in the casing c, through which the foremen and others
sign their names and it is geared with and receives motion from the drum d,
by the toothed wheels g, h, or equivalent means. The paper after passing round
the spiked drum f, and being signed upon may either fall into a space below
or it may be coiled on a drum fixed on the spindle of the first mentioned drum a,
Guide or couch rollers k, l, covered with felt or equivalent material are provided
in conjunction with the spiked drum d, in order to conduct the paper to and
from the said drum and to afford a resisting medium to the spikes in entering
the paper.
Under another arrangement illustrated at figure 18, the paper to be signed
upon is presented in proper position by a disc a, secured on the spindle b, actuated
by the clock and having a series of pins fixed in its periphery. These pins .at
certain times act on one end of a lever c, the other end of which has a pin fixed
or formed in it which enters holes or recesses in the side of a drum d, the said
drum having spikes in its circumference to draw the paper round into position for
being signed upon.
On a drum e, projecting from the side of the drum d, and connected with it and
on another drum f, underneath opposite ends of a chain or cord g, are attached and
wound the said cord at an intermediate position, between these two drums, passing
over and under rollers h, i.. On the loop of the cord or chain where it is doubled
back at the roller h, a weight k, is hung. Between the drums d and ƒ a flat
board is situated over which the paper passes to be signed upon.
The action of this apparatus is as follows, when a pin on the disc a, comes in
contact with the end of the lever c the pin or tooth in the other end of the said
lever is released from the hole or recess in the side of the drum d in which it
bad previously been situated and the weight k, then pulls the drum d, round
until another hole or recess comes opposite the pin or tooth on the lever. This
action on the drum d, pulls the paper downwards. from the drum m, on which
it is coiled and presents a new surface to be signed upon, the paper already
signed on being at the same time wound on the drum n, which is connected to
the drum f.
An endless band o, is also provided fitted with pins which perforate the paper
and further indicate the time at which a signature is made.
Another alternative arrangement for this part of the apparatus illustrated in
plan at figure 19 sheet 1 consists in winding the paper to be signed upon on a
drum a, and thence passing it over a larger drum b,, situated on the spindle c,
operated by the clock. Upon leaving the second drum b, the paper is coiled on a
third drum d, which has a druin e, attached to the side of it and by means of
a cord passed round the said drum e, and a weight attached to the said cord a
tension is exerted on the ribbon of paper. The drum b, is set with pins or teeth
to draw the paper in the required direction and the said pins may perforate
the paper and indicate the time at which any part of it is exposed for signature.

page_text: Under another arrangement illustrated by figures 20, and 21 sheet 1 a flat
piece of paper ruled off into divisions corresponding to different periods of time
is used to check the arrival and departure of the foremen and others in charge the
said piece of paper being secured on a rectangular board a, and reciprocated by the
clock work, so as to bring the various divisions in one line or row opposite the
signing orifice during the day.
This reciprocation of the board a, may be effected by attaching a series of racks b,
to the back of the board a, and gearing a wheel c, there with. The wheel c, is
situated on a spindle d, on which a bevil pinion e, is also secured and geared
with a similar wheel f'fixed on the spindle g actuated by the clock. The racks b,
have teeth both above and below so as to reciprocate the board in opposite directions
alternately.
From each side of the board a, a series of rods h, extend horizontally the said
rods resting in hooks or jaws formed around the circumferences of discs k, formed
or fixed on the ends of drums l. In the side of one of the discs k, a series of boles
is made into which a pin or tooth formed on one end of a lever m, enters the other
end of the said lever being once each working day acted on by a pin fixed in the
periphery of a disc n, secured on the spindle d. On each of the drums l, a cord or
chain is wound and when the pin or tooth of the lever m, is released from a hole
in the side of the disc k, the drums 7, are pulled round thereby allowing the board a,
to fall so as to bring a new row of spaces on the paper in line with the signing
orifice X, and the said spaces in the row are in succession brought opposite the said
orifice by the reciprocating action of the wheel c on the rack b.
Instead of the discs k, and n, and apparatus in connection therewith for effecting
the vertical movements of the board a, a continuous rack may be employed for
that purpose as indicated at t, figure 22, sheet 1. A wheel t¹, fixed on a spindle
actuated by the clock gears with the rack t the said spindle passing through or
being situated in a groove or slot at the back of the board and made parallel with
the rack t.
Under another mode illustrated at figure 23 sheet 1 the paper to be signed
upon by the foremen managers and others in charge is placed on a horizontal
table a, fixed to and rotating with the shoot b. An opening is made in the top
of the casing c, containing the check box which opening is provided with a
shutter d, capable of being shifted to a greater or less distance from the centre
of the apparatus so as to enable signatures to be made in concentric rings around
the paper. The shutter d may be moved by hand and locked in the required
position or it may be actuated mechanically from the clock spindle e.
Another part of my said Invention relates to improvements on the check boards
referred to in the specification filed in pursuance of my previous Letters Patent,
and as shewn at figures 24, and 25 sheet 1 the improvement consists in mounting
each board a, upon rollers b, rotating between guides c and in providing each board
with a pulley d. In conjunction with each pulley d, another pulley e rotating
loosely on a shaft is provided and a cord or chain one end of which is secured at f
or other convenient position is passed over and under the pulleys d, e, in the
manner shewn to a weight g, At their other ends or sides the check boards are
held together by a catch or bolt h, operated by a rack i, and pinion k, which latter
is situated on or geared with the spindle operated by the clock or an equivalent
arrangement actuated by the clock may be used. The effect of the arrangement is
that when the bolt or catch h, is withdrawn from the board a, by the pinion k,
being at a certain time rotated, the weight g acting on the cord or chain draws the
board a, forward so as to expose the checks hanging thereon similarly with the
boards a¹ and a², of which any desired number may be provided. The arrangement
may be placed horizontally, vertically or in an inclined position."
Another part of my present Invention relates to improvements in the clock work
mechanism by which the moving parts of the apparatus herein before described with
reference to sheet 1 of the appended drawings as well as the moving parts of the
J.
.

page_text: apparatus described in the specification filed in pursuance of my said previous .
Letters Patent are actuated.
One of the said improved arrangements of clock work is illustrated by the several
figures on sheet 2 of the drawings annexed hereto, figure 1 being a front elevation
figure 2, a plan and figure 3, an end elevation whilst figure 4, is an elevation of part
of the back frame A, shewing certain parts of the mechanism and figures 5, 6, 7, 8,
and 9 are details of certain of the other parts.
On the drawing the face of the clock is removed and the "going" mechanism
is not shewn as it constitutes no part of the Invention and may be of any suitable
construction.
The mechanism for actuating the time checking apparatus consists of a barrel C,
which turns round once in each hour being geared to the going part of the clock
by the spur pinion a, situated on the spindle of the barrel C, and geared with a
wheel b, carried on a spindle f, supported in the front frame B, and in a bracket c
secured to the said frame. The wheel b, is geared to the minute hand of the clock
by the pinion d, situated on the minute hand spindle. The barrel C, is divided
equally throughout its length into 12, 24 or, other desired multiple of the spaces
and in certain of the division lines pins c, are inserted which correspond to certain
hours and parts of an hour during a day. In conjunction with these pins e, a lever D,
is employed the said lever being connected to a sleeve and disc E, sliding on guide
rods constituting part of a frame F, which is carried in brackets G, as more
particularly seen in plan at figure 2. The disc E, is connected by a chain f, to the
upper extremity of a lever H, centred at its other end on a pin fixed in the frame B,
and the said disc is also connected by the chain to a weight g. Between the disc
and the lever H, the chain ƒ passes round a guide pulley i and it also passes over
a guide pulley h, between the disc and the weight g: The lever H, is provided
with a spring, as more particularly seen at figure 3, which has a pin k, fixed in it
passing through a hole in the lever so as to be acted upon by the stepped periphery
of a cam or "snail" I, which is situated loosely on the hollow spindle of the hour
band I, of the clock. The hour hand receives motion from the spindle through
the pinion m, situated thereon gearing with the wheel n, on the hollow spindle of
the hour hand and the cam or "snail" 1, also receives motion from the said.
spindle through the pinion o, gearing with the wheel J, situated loosely on the
hollow spindle of the hour hand and connected to the cam or "snail." Figure 5; is
a detailed view of the arrangement of the spindle fand the wheel b, and pinions m. o;
thereon and figure 6, is a detailed vertical section shewing the method of arranging
the wheels n, and J, on the hour hand of the clock. The cam or "snail" I, is
attached to the projecting collar J₁ on the boss of the wheel J, by screws or
equivalent means: In conjunction with the lever H, another lever K, is provided
and centred at its upper end on a shaft L, extending between the frames A, B, and
having a projecting pin K', in its lower end As more particularly seen at figure 4;
and in detail at figure 8, another lever M, is centred near the opposite extremity of
the shaft L, and the outer or free end of the said lever has a pin or roller fixed in
or attached to it which acts on a cam p, secured on another shaft q, as shown in
dotted lines at Fig. 4 also extending between the frames A, B. On the shaft q,
another cam r, seen in detail at figure 7, is fixed which acts on a roller 8, carried
on a pin fixed in the lower extremity of a lever N, centred at N', on the frame B.
The upper extremity of the lever N, is connected by a link N', to a crank t, fixed
on the central spindle of the frame F, and at a point between the centre N¹ and
the lower end of the lever N, a heel or piece u, is secured to the lever and projects
at right angles therefrom through a slot to the interior of the frame B, where it, at
certain times, acts on a pin w, fixed in the side of a spur wheel w', as hereinafter
more particularly referred to. The shaft q, is rotated at certain times by the action
of a coiled spring in the drum or barrel O, which barrel is carried on a shaft O¹, and
has a spur wheel P, at one end of it. The wheel P, is geared with a spur pinion Q,
carried on a shaft Q', and on which a spur wheel R, is also fixed and geared with a
pinion R', on the shaft q. The shaft q, has also a spur wheel q; fixed on it which

page_text: gears with a pinion v, on the shaft w², carrying the before mentioned wheel w¹,
The wheel P, on
which wheel gears into a pinion w³, on the axis of the "fly" x.
the spring barrel or drum O, is also geared with a pinion S, by which motion is
communicated through a pinion T, to a shaft U, carrying a bevil wheel V, which
gears with a corresponding wheel V', fixed on the upper end of a vertical spindle W,
whose lower end has a jaw W₁ formed on or secured to it and in the said jaw the
upper end of the spindle of the time checking apparatus is held so as to turn witli
the spindle W. when motion is communicated to the said spindle.
"
The action of the improvements in the clock is as follows:-The barrel C, and
the cam or "snail" I, being rotated by the clockwork as herein before described
as each succeeding step on the periphery of the cam or "snail comes opposite the
pin k, in the spring j of the lever H, the lever D, and the disc E, are by the action.
of the weight g, pulled sufficiently forward to bring the point of the lever D,
opposite another division on the barrel C, throughout the 12, 24 or other number
of hours into which the barrel is divided. When a pin e, on the barrel C, comes
opposite the end of the lever D, the said end of the lever is raised and the frame F,
is caused to move through an arc in the direction of the arrow figure 1. This has
the effect through the intervention of the crank t, and connecting rod N2, of raising
the lower extremity of the lever N, and of lifting the heel or piece u from contact
with the pin w, in the side of the spur wheel w', and also of raising the roller s
out of the hollow x, in the cam r, figure 7 which being effected the brake on the
spring in the drum or barrel O, is removed and the said spring causes the spur
wheel P to rotate. The said wheel through the intervention of the gearing herein-
before described causes the spindle W and with it the spindle of the time checking
apparatus to rotate sufficiently to cause another time to be indicated. The spindle W,
is caused to stop rotating at the proper time by the shaft q, in rotating again
presenting the hollow part of the cam r opposite the roller 8, of the lever N.
The lower end of the said lever then falls and through the action of the connecting
rod N2 and crank t, brings the point of the lever D, into position to be acted on
by a succeeding pin on the barrel C. The fall of the lever N, at the same time
brings the heel u into position to act on the pin w, in the side of the spur wheel w',
which stops the further action of the "fly" x¹. Each time the shaft q is rotated the
free end of the lever M is raised by the cam r, thereby partially rotating the
shaft L, and moving the lever K, in the direction of the arrow figure 1. This
action of the lever K, is inoperative until the lever D, has arrived at the end Y, of
the barrel C, at which time the pin k in the spring of the lever H, comes in
contact with the piece y of the cam or "snail" I, the edge of which piece is
bevilled so as to push the pin k, and the spring j backwards sufficiently to cause
the pin K', in the end of the lever K, to come against the spring j, during the next
oscillation of the lever and throw the lever H, back into position for beginning
another days checking that is to say the lever D, is moved from Y to Z.
Another improved arrangement of the clock work is illustrated on sheet 3, of
the drawings on which figure 1 is a front elevation figure 2, an end elevation
figure 4, a plan and figure 3, an elevation of part of the back frame shewing certain
parts of the apparatus whilst figures 5, 6, 7, 8, 9 and 10 are detailed views of
certain other parts. In this arrangement the barrel C, is dispensed with and a
wheel or "snail" A, with teeth only on certain parts of its periphery corresponding
to the times at which a check is desired to be taken is employed in lieu thereof.
The wheel is centred on a stud B, and it is geared with the hour hand F, of the
clock by the wheel D, to which the said "snail" is screwed and by a pinion E
situated on the hollow spindle of the hour hand. Motion is communicated to the
hour hand by a wheel a, also situated on the hollow spindle thereof and geared to
the spindle of the minute hand G, by the spur gearing b, c, d, the latter wheel
being on the spindle of the minute band. The teeth of the "snail" A, gear with a
pawl H, formed on or attached to a lever H¹, which is centred on a pin or stud
fixed in the front frame I, of the clock and has another pawl formed or fixed thereon
as more particularly seen at fon the detailed views figures 5, and 6, which latter-
11

page_text: pawl at certain times is acted upon by pins fixed in a disc g also centred on the
spindle of the minute hand of the clock. Figures 7, and 8, are detailed views of the
disc g. The other end of the lever H', has a pin or roller fixed in or attached
thereto which at certain times acts on so as to raise another lever K, centred at K!,
and carrying a roller h, on a pin or stud fixed at right angles to the length of the
lever in its rearward end. The said roller h is, while the spindle W, is stationary,
situated in a hollow in a cam i, fixed on a shaft j, which is geared to, the spring.
barrel or drum O, by spur gearing P, Q, R. S the said drum or barrel being also
geared to the spindle W, by the spur gearing T, and bevil gearing U, in the manner.
hereinbefore mentioned The lever K, has a projecting heel or side piece L, which
acts on pins m, n fixed in the side of the wheel o, by which motion is given to the
"fly" p. When the heel 7 is released from contact with the pin n, warning is
given that the spindle W, is about to turn and when it is released from and
inaintained out of contact with the pin m, the spring in the barrel o, and train of
wheels in connection therewith is set in motion. This arrangement of the improved,
clock is provided with a gong L. which is struck by the hammer L', and sounded
every time the spindle W, is turned round and to effect this a wheel is secured
on the shaft j, and geared with a pinion g¹, on the shaft.q. A pin r, is fixed in
the side of the wheel g, which as the wheel rotates strikes against and raises a
lever 8, secured on a shaft s¹, on which the hammer L' is also centred. By raising
the lever the hammer is raised from the gong L, and immediately the pin r, has
passed the lever 8, the hammer is brought against the gong with force by a
spring t acting on a pin x, fixed in the shaft s'.
"
The action of this arrangement of the clock is as follows. When a tooth of the
" snail
A, in rotating comes in contact with the pawl H, the rear, end of the
lever H, is slightly raised and the other pawl f. is depressed and brought into
position to be acted upon by one of the pins set round the disc g. The action of
the pins in the rotation of the disc further raises the free end of the lever H¹, until
it comes in contact with and elevates, the free end of the lever K, sufficiently to
raise the roller k, free of the hollow in the cam i, and causes the said roller to ride.
over the wider portion of the camı. At the same, time the heel 1, of the lever K, is
raised from contact with the pin m. in the wheel o, and the brake being thus
removed from the drum O, the spring therein causes the spindle W, to be turned.
partially round and the gong L, to be sounded through the intervention of the
mechanism hereinbefore described. In order to enable the spring drum' O, and
apparatus connected with it to be turned round when the going part of the clock
is stationary or for purposes of adjustment a lever X, is provided on the shaft 8'.
To one end of the lever a cord is attached by pulling which the roller h, is lifted
out of the hollow of the cam i, and the heel l, from contact with the pins m, n. A
dial shewn in detail at figure 9. is or may be secured to the back frame at the
position indicated in dotted lines at Y, figure 3, for the purposes of adjusting the
hands of the clock, the index or pointer for the said dial being secured on and
rotating with the shaft Y', on which the spur pinions b and c are fixed.
Another alternative arrangement of the clock work mechanism is illustrated at
figures 1 and 2 sheet 4 of the drawings and it consists in dispensing with the
barrel C, shewn on sheet 2. and employing in lieu thereof a chain A, having 360,
720, or other convenient number of links each link representing a minute or other
period of time. The chain is preferably situated at the back of the clock and it is
passed over pulleys B, one of which is a sprochet wheel and is actuated from the
going part of the clock by a spur wheel fixed on its shaft or spindle in the same
manner as the barrel C, sheet 2. The oscillating frame F, lever D, crank t, link N²,
and apparatus connecting the link to the roller s acting on the cam 7 sheet 2 are
retained in this arrangement and in certain of the links of the chain pins are fixed
which acting upon raises the point of the lever D and so operates the discharging
mechanisin and permits the spring barrel to partially rotate the spindle connecting
the clock to the time checking apparatus.
Under another alternative arrangement illustrated at figure 3 sheet 4 a screw

page_text: with 24 or other number of threads is substituted for the barrel C, and projecting
pins are placed either in the hollow or ridge of these threads. By this means the
stepped cam or "snail" I, sheet 2 is dispensed with, the lever D, on arriving at
the end of the screw being brought back into position for commencing another
series of checking operations by the weight g.
Two or more checking machines and series of check boards may be actuated from
one clock constructed under any of the modifications hereinbefore described by
means of an endless band connecting rods, cranks or eccentrics or a combination of
any or all of them.
:
The doors for affording access to the interior of the checking apparatus instead
of being hinged as formerly are now preferably constructed to slide in grooves.
Having now described and particularly ascertained the nature of my said
Invention and the system, mode or manner in or under which the same is or may
be used or carried out in practice I would observe in conclusion that what I
consider to be novel and original and therefore claim as the Invention secured to
me by the hereinbefore in part recited Letters Patent. is.
