Improvements in Apparatus for Recording and Checking Workmen's
Time, and for other similar purposes.
I, WILLIAM WHITEHEAD, of 104 Moss Lane West, Moss Side, Manchester,
in the County of Lancaster, Electrical Engineer, do hereby declare the nature of
this invention to be as follows :-
The object of this invention is to provide an apparatus whereby the time of
arrival or departure of workmen or clerks in places of business, or that of trains
at or from stations or signal boxes or at other points, or that of ships passing
others or points, or that of callers at offices or other places and the like time, can
be recorded automatically and accurate to the minute and such record readily
examined and filed.
The component and essential parts of which this apparatus consists, are:-a
primary clock, controlling a secondary clock work or primary clock only, a
stamping mechanism, an electric battery or other electric source, a counter, a roll
of paper and signal bell, wholly or partly enclosed in a casing. The said secondary
clock work controlled by the primary clock, which may be that of a works or
other place as the case may be, is actuated by means of springs, weights or an
electric current. In the said secondary clock work, a peg wheel is employed in
connection with an electro magnet and its armature, which forms an electric
escapement. The said armature is a lever operating in connection with the said
peg wheel, the periphery of which is formed with teeth of the shape known as
tractrix curve teeth, on which rides the end of a lifting lever connected by a
rod to the main intermediate lever of the stamping mechanism hereinafter fully
described. The wire of the electric circuit is connected with an electric battery
or other electric source and further continued to a circuit closer, attached to the
minute wheel arbor of the main or controlling clock aforesaid.
The stamping mechanism is arranged on two frames, one placed inside the other.
The outside or inain frame has mounted at one end the main spindle furnished at
one end with a handle arranged to lock itself in position at the end of each
revolution. On this main spindle are fixed two cams positioned respectively outside
the said main frame, on the top of which cams rest the free ends of a padded
impression lever, which are kept in contact therewith by means of a spring suitably
arranged. The said impression lever carries an endless inking ribbon or an inking
roller may
be used in connection with the said impression lever in a manner as
will be well understood and moved automatically by suitable mechanism.
Underneath the cam, on the handle side of the main frame is pivoted to the
latter a straight lever, the free end of which is connected to a counter of con-
venient construction suitably positioned. The said lever, by means of a spring
suitably arranged, is kept in contact with the underside of the said cam, so that
one revolution of the aforesaid handle will depress the said lever once, thus moving
the counter one number. The front face of the second cam is furnished with a
stud having attached a rod connected to a quadrant, whereby a rocking motion is
imparted to the latter on every revolution of the aforesaid handle. This quadrant
is in gear with a segmental pinion fitted loosely on a shaft, suitably mounted in the
main frame, which shaft carries a paper feed roller arranged in connection with a
pressure roller. The said segmental pinion has attached a spring pawl, which
engages a ratchet wheel, fixed behind the said segmental pinion on the feed roller
shaft, in such a manner, that on each down movement of the aforesaid quadrant,
the paper feed roller is partly rotated for the purpose of intermittently passing
the paper strip through the stamp, the action of which latter will be hereinafter

page_text: described. The strip of paper used is drawn by the said feed rollers, from a roll
suitably suspended in the casing of the apparatus, over a fixed plate arranged
underneath a slot, termed the "recording slot," thence back over a carrier roller,
positioned at the edge of the said plate, between the impression lever and type
wheels and afterwards into the hold of the said casing.
On the quadrant side of the main frame, is arranged to rock, the main inter-
mediate lever aforesaid, which is arranged to be locked in position, whilst the
stamp is in use, in order to prevent its type changing and to be released the moment
the impression lever leaves it. This locking device consists of a rod arranged to
rock in suitable bearings, on the respective side of the main frame parallel with the
main intermediate lever. The end of the said rod near to the stamp is formed
with a leg
or arm at a right angle thereto and brought under the influence of a
spring. The other end of the said rocking shaft is furnished with a stud, operated
upon by another stud fixed onto the said quadrant. The said spring has the
tendency of retaining the said leg or arm in contact with the main intermediate
lever whilst the stud on the quadrant, when coming into contact with the stud on
the rocking shaft, lifts the said leg or arm through the rocking lever off the main
intermediate lever and thus releases it at the proper moment.
The foregoing, with the exception of the main intermediate lever, deals with
the mechanical part of the apparatus operating independently of the electrical
control.
The
The stamp employed to print the time onto the paper strip aforesaid, consists of
a frame placed inside the main or outer frame, carrying type, ratchet and locking
wheels and their respective cams, levers, pawls and springs hereinafter more fully
described. Each of the said type wheels on one side is formed with a cavity,
which contains a locking and a ratchet wheel and cam, positioned one inside the
other, a suitable space being left between the same. The first of the said type
wheels operated, is the units (minute) wheel having numbers on its periphery 0-9.
The second type wheel is the tens (minute) wheel, its periphery being divided into
twelve equal parts, viz., two blank spaces opposite to each other and numbers 1-5
between the same respectively, the said two type wheels indicating. the minutes in
the hour. The periphery of the third type wheel is divided into 12 equal parts
carrying numbers 1-12 representing twelve hours and the periphery of the
fourth type wheel, which is positioned on the left of the units type wheel, into
12 equal parts carrying 6, "a.m.'s" and 6, "p.m.'s" in alternate order.
a.m." and " p.m. type wheel together with the units and tens (minute) type
wheels, ride upon a sleeve, fixed to the hour wheel, which sleeve revolves on a
spindle carried by the aforesaid inner frame. The object of the said sleeve is to
communicate motion from the said hour type wheel, through the units and tens
type wheels, to a cam, fixed on the end of the said sleeve, for the purpose of
operating the "a.m.'s" and "p.m.'s" type wheel, thus for instance placing the type
in the following successive order -6.15 a.m. The cam of the units (minute)
type wheel engages with a cam lever communicating through the tens (minute)
type wheel lever, motion to the tens (minute) type wheel. The tens (minute) type
wheel has a double cam corresponding with the double set of numbers on its
periphery as aforesaid. The said tens (minute) type wheel cam, is connected by
means of a second cam lever to the hour type wheel lever, so as to move the
hour type wheel, every half revolution, one division. The hour wheel then in its
turn at each revolution communicates motion, through the sleeve and cam aforesaid,
to a third cam lever, attached to the motion lever of the "a.m.'s" and "
p.m.'s
type wheel, thus moving the latter one division. The aforesaid motion levers are
arranged to oscillate on a spindle at the bottom of the inner frame, the upper
ends thereof being furnished with pawls, adapted to engage the respective type
ratchet wheels, each lever and each pawl being respectively under the influence of
a spring, to ensure of maintaining the pawls always in contact with the ratchet
wheels. On each side of the locking wheels aforesaid is fitted to the base of the
inner frame, a locking lever, under the influence of a spring, the upper ends of

page_text: which levers are formed with a small pin or tooth adapted to engage in holes or
notches at opposite points in the locking wheel, for the purpose of locking the type
wheels when in use. Between each pair of the said locking levers towards the
base thereof, is employed on a spindle a disc, furnished with a long bearing and
a trip lever. A portion of the periphery of the said discs opposite to each other
is cut away, thus forming two flats on each disc, against which flats the locking
levers are held by a suitable spring when the type wheels are locked. The type
wheels are furnished with tripping pins which when operated come into contact
with the points of the trip levers thus tilting their respective discs, thereby
opening the locking levers and immediately allowing the same to close and ride
on the locking wheels in readiness for engaging the next holes or notches. The
units type wheel lever, has at right angles thereto an arm, furnished with a pin
which engages through a link the main intermediate lever between the stamp and
secondary clock work. The trip lever in connection with the first or units
(minute) type wheel is furnished with a small star wheel brought under the
influence of a spring in such a manner, that on the units (minute) type wheel
lever receding, the star wheel revolves loosely on the trip lever point, whilst on
approaching, it engages and imparts motion thereto and releases it in time that
it may resume its locking position before the respective division is passed.
As a check against improper use of the apparatus, especially by workmen, a
signal bell is connected therewith giving one signal on every revolution of the
main spindle.
The working of the electrically controlled portion of the apparatus described,
is as follows:-
:-
The electric circuit closer of the main or controlling clock, closes the circuit at
each revolution of the minute wheel for a period of about two seconds. During
this time the electric current flows from the electric battery or other electric
spurce, through the circuit closer, the leading wires, thence around the electro
magnet of the secondary clock aforesaid and back to the electric battery or other
electric source. This causes the electro magnet to attract its armature together
with the escapement lever of the secondary clock, allowing the peg wheel to escape
one peg or division. On the current ceasing to flow, the armature is drawn back
by its spring to a stop, so as to be in position for the next impulse. The "tractrix
curved teeth on the periphery of the said peg wheel, in moving one division, lifts
the lever in contact therewith which, through the connections hereinbefore
described between the same and the arm of the lever of the units (minute) type
wheel, causes the said type wheel lever to be drawn back. The lever riding on the
tractrix curved teeth, after being lifted one division of the peg wheel, escapes
the end of the tooth and falls on the base of the next one. This allows the units
type wheel lever spring, to force its lever and pawl forward and thus carry the
units (minute) type wheel forward one division. The above movement repeated
nine times completes a revolution of the units (minute) type wheel and its cam,
which latter then drops the cam lever, connected to the lever of the tens (minute)
type wheel, thus allowing the spring of the said lever to push its lever and pawl
forward so as to move the tens (minute) type wheel one division. In a like
manner the hours type wheel is actuated by the tens (minute) type wheel at every
half revolution, the latter in its turn actuating the "a.m.'s and "p.m.'s" type
wheel through the sleeve and cam aforesaid at every revolution.
"
17
In order that the type wheels may not shoot past their respective divisions the
special locking device is now brought into action as herein before described. The
hour and the "a.m.'s" and "
p.m.'s type wheels are operated and locked in the
same manner as the tens (minute) type wheel, the latter having two sets of numbers
on its periphery, it actuates the locking gear and other parts of the bour type
wheel every half revolution, whereas the a.m.'s
and p.m.'s type wheel is
22
actuated only once every revolution of the hour type wheel.
73
In order to render the speed of the type wheels relative to each other clear. it
may be mentioned, that to one revolution of the slowest or "a.m.'s" and "
p.m

page_text: type wheel, the hour type wheel makes twelve revolutions, the tens (minute) type
wheel 72 revolutions, and units (minute) type wheel 864 revolutions.
The mechanical part of the apparatus is operated as follows:-
The workman, clerk, or other person using the apparatus for the purpose of
recording his time of arrival or departure writes or stamps his number or name
as the case may be, or when used in signal boxes, the signal-man records the
particulars of the passing trains, or when used on ship-board the man on watch
records the passing of other ships or point or other matter of interest, through the
recording slot onto the paper strip below the same and afterwards imparts one
turn to the handle. The first half of the revolution of the main spindle removes
the impression made from underneath the slot, to the stamp, by means of the
feeding gear previously described, in the meantime positioning for action the
locking arm or leg on the main intermediate lever and also registering the number
on the counter. The second half of the revolution of the main spindle lowers the
impression lever together with its inking device and paper strip aforesaid, thus
receiving the impression from the type wheels aforesaid, whilst the signal bell is
rung in the meantime and the locking arm or leg finally lifted and all parts
brought into their normal or first position.

Improvements in Apparatus for Recording and Checking Workmen's
Time, and for other similar purposes.
I, WILLIAM WHITEHEAD, of 104 Moss Lane West, Moss Side, Manchester,
in the County of Lancaster, Electrical Engineer, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The object of this invention is to provide an apparatus whereby the time of
arrival or
departure of workmen or clerks in places of business, or that of trains at
or from stations or signal boxes or at other points, or that of ships passing others
or points, or that of callers at offices or other places and the like time, can be
recorded automatically and accurate to the minute and such record readily
examined and filed.
And in order that my invention may be more fully understood I have caused
to be appended hereunto two sheets of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1. Sheet I, is a side view, Fig. 2 a front view, and Fig. 3 a back view of the
casing of the apparatus partly in section showing the various parts of its
mechanism.
Figs. 4 & 5, Sheet II, are side views, Fig. 6 a longitudinal section of the
stamping mechanism shown in position in the casing.
Fig. 7 is a plan of Fig. 4, and
Figs. 8 & 9 end views of the stamping mechanism without casing.
Fig. 10 a vertical section of the type wheels thereof.
In carrying out my invention and referring to Sheet I, the component and
essential parts of which this apparatus consists, are:-a primary clock, (not
shown,) controlling a secondary clock work a (or primary clock only) a stamping
mechanism b, an electric battery or other electric source, (not shown) a counter c,
a roll of paper d and signal bell e, wholly or partly enclosed in a casing. The
secondary clock work a, controlled by the primary clock, (not shown,) which
may be that of a works or other place as the case may be is actuated by means of
springs, an electric current, or by a weight a'. In the secondary clock work a, a
peg wheel a is employed in connection with an electro magnet and its

page_text: armature a, which forms an electric escapement. The armature a is a lever
hinged at one end to the body of the magnet a³, the other end carrying a rod að
connected to the end of the escapement lever a in connection with the peg
wheel a², the periphery of which is formed with teeth a of the shape known
as "tractrix curve "teeth on which rides the end of a lifting lever a connected by
a rod a to the main intermediate lever g of the stamping mechanism hereinafter
fully described. The wires h of the electric circuit are connected with an electric
battery or other electric source (not shown) and further continued to a circuit
closer, (not shown) attached to the minute wheel arbor (not shown) of the primary
or controlling clock (not shown) aforesaid as will be well understood.
The stamping mechanism b, see Sheet II, is arranged on two frames i & k, one
placed inside the other. The outside or main frame i has mounted at one end the
main spindle furnished at one end with a handle &, see Figs. 1 & 2, arranged to
lock itself in position at the end of each revolution by such as a spring stud b.
On this main spindle are fixed two cams positioned respectively outside the
main frame i, on the top of which cams & rest the free end of a padded
impression lever l, pivoted to each side of the frame i, which are kept in contact
therewith by means of a spring suitably arranged, see more particularly
Figs. 6 & 9. The impression lever carries an endless inking ribbon guided
underneath the frame i, by means of the rollers P, P, & P. The roller serves for
the supply of ink to the ribbon 12 and is intermittently rotated by means of a
ratchet wheel and pawl which latter receives motion from a straight lever m
pivoted to the handle side of the frame i, whereby the ink ribbon is gradually
inoved underneath the impression lever l. In lieu of the inking ribbon described,
an inking roller may be used in connection with the impression lever in a manner
as will be well understood and moved automatically by suitable mechanism
(not shown).
The straight lever mis positioned underneath the cam and its free end
connected by means of the rod m¹ to a counter e, see more particularly Sheet I, of
any convenient construction preferably positioned below the clock face a. The
lever m by means of a spring in the counter c is kept in contact with the underside
of the cam b', so that one revolution of the handle 6 will depress the lever m once
and thus move the counter cone number. The front face of the second cam, see
Figs. 5 & 9, is furnished with a stud a having attached a link n' connected to a
quadrant arranged to oscillate on a stud n³ fixed to the respective frame side i,
whereby a rocking motion is imparted to the quadrant n' on every revolution
of the handle. The quadrant n² is in gear with a segmental pinion n* fitted
loosely on a shaft n suitably mounted in the main frame i, which shaft n' carries a

On the quadrant side of the main frame i, arranged to rock, the main inter-
mediate lever g, which is arranged to be locked in position, whilst the stamp bis in
use, in order to prevent its type changing and to be released the moment the
impression lever leaves it. This locking device consists of a shaft 7 arranged to
rock in suitable bearings ', on the respective side of the main frame i parallel with
the main intermediate lever g. The end of the shaft 7 near to the stamp b

page_text: is formed with a leg or arm q² at a right angle thereto and brought under the
influence of a spring 7. The outer end of the rocking shaft is furnished with a
stud operated upon by another stud n fixed onto the quadrant n². The spring 3
has the tendency of retaining the leg or arm q in contact with the main inter-
mediate lever 9: whilst the stud n on the quadrant n², when coming into contact
with the stud on the rocking shaft g, lifts the leg or arm 2 (through the action
of the rocking shaft y) off the main intermediate lever y and thus releases it at the
proper moment.
The foregoing, with the exception of the main intermediate lever deals with
the mechanical part of the apparatus operating independently of the electrical
control.
::
The stamp employed to print the time onto the paper strip d¹, consists of
a frame & placed inside the main or outer frame, carrying type wheels », ², r², ³,
ratchet wheels s, and locking wheels t and their respective cams u, cam levers u',
locking levers, pawls w and springs a¹, a hereinafter more fully described. Each
of the type wheels 1, 1, 2, 3, on one side is formed with a ratchet and a locking
wheels & t and cam u, positioned one inside the other, a suitable space being left
between the same. The first of the said type wheels operated, is the units (minute)
wheel having numbers on its periphery 0-9. The second type wheel is the
tens (minute) wheel, its periphery being divided into twelve equal parts, viz., two
blank spaces opposite to each other and numbers 1-5 between the same respectively,
the two type wheels & indicating the minutes in the hour. The periphery of
the third type wheel 2 is divided into 12 equal parts carrying numbers 1-12
representing twelve hours, and the periphery of the fourth type wheel which is
positioned on the left of the units type wheel 7, into 12 equal parts carrying
6, "a.m.'s" and 6, "p.m.'s" in alternate order. The "a.m.'s and p.m.'s type
wheel together with the units and tens (minute) type wheels 7, r', ride upon a
sleeve, fixed to the hour wheel 2, which sleeve revolves on a fixed spindle k
carried by the inner frame k. The object of the sleeve is to communicate motion
from the hour type wheel through the units and tens type wheels, to
the cam, fixed on the end of the sleeve for the purpose of operating the
a.m.'s" and "p.m.'s" type wheel 3, thus for instance placing the type in
the following successive order :-6.15 a.m. The cam u of the units (minute)
type wheel engages with a cam lever u¹ communicating through the tens (minute)
type wheel pawl lever w, motion to the tens (minute) type wheel. The tens
(minute) type wheel has a double cam u corresponding with the double set
of numbers on its periphery as aforesaid. The tens (minute) type wheel cam
connected by means of a second cam lever u¹ to the hour type wheel pawl lever w
so as to move the hour type wheel 2, every half revolution, one division. The
hour type wheel then in its turn at each revolution communicates motion, through
the sleeve and its cam u to a third cam lever u', attached to the pawl lever w of
the "a.m.'s" and "p.m.'s" type wheel ³, thus moving the latter one division.
The pawl levers we are arranged to oscillate on a spindle at the bottom of the
inner frame, the upper ends thereof being furnished with pawls, adapted to
engage the respective type ratchet wheels each lever w¹ and each pawl being
respectively under the influence of a spring a, a, to ensure of maintaining the
pawls ac always in contact with the ratchet wheels s. On each side of the locking
wheels is fitted to the base of the inner frame k, a locking lever v, under the
influence of a spring the upper ends of which levers are formed with a small pin
or tooth, adapted to engage in holes or notches at opposite points in the
locking wheel t, for the purpose of locking the type wheels when in use. Between
each pair of the locking levers towards the base thereof, is employed on a
spindle p, a disc, furnished with a long bearing p² and a trip lever p A portion
of the periphery of the discs p' opposite to each other is cut away, thus forming two
flats on each disc p, against which flats, the locking levers are held by the
spring, when the type wheels 1, 1, 2, 3 are locked. The latter are furnished
with tripping pins s¹ which when operated come into contact with the points of the
is

page_text: trip levers p³ thus tilting their respective discs p¹, thereby opening the locking
levers and immediately allowing the same to close and ride on the locking
wheels t in readiness for engaging the next holes or notches ³. The units type
wheel pawl lever w', has a boss forming a long sleeve w³ with an arm y at right
angle, furnished with a pin y' which engages through a link y' the main, inter-
mediate lever y between the stamp and secondary clock work a. A trip
is furnished
lever pin connection with the first or units (minute) type wheel,
with a small star wheel = brought under the influence of a spring pawl i.
The lever we of the units (minute) type wheel has at its base a projection with a
tooth at its free end, which ou approaching the star wheel engages it and thereby
imparts motion to the trip lever p' and tilts the disc pl, thus opening the locking
lever whilst on the said tooth receding the star wheel is permitted by the
spring pawl to revolve so as to leave the locking levers at rest.
»
As a check against improper use of the apparatus, especially by workmen,
a signal bell e s connected therewith, giving one signal on every revolution of
the main spindle, a pin el being fixed on the latter, which lifts
spring blade e
having attached the bell hammer e³, whilst a catch e prevents the handle being
turned in the wrong direction.
The working of the electrically controlled portion of the apparatus described, is
as follows:-The electric circuit closer of the main or controlling clock (not
shown) closes the circuit at each revolution of the minute wheel (not shown) for a
period of about two seconds. During this time the electric current flows from the
electric battery or other electric source, through the circuit closer, the leading
wires h, thence around the electro magnet of the secondary clock work u
and back to the electric battery or other electric source (not shown). This causes
the electro magnet a³ to attract its armature a' together with the escapement
lever a of the secondary clock a, allowing the peg wheel a to escape one peg or
division. On the current ceasing to flow, the armature a is drawn back by
its spring a to stop, so as to be in position for the next impulse. The "tractrix
curved teeth on the periphery of the peg wheel a², in moving one division, lifts
the lever in contact therewith, which, through the connections hereinbefore
described between the same and the army of the pawl lever w¹ of the units
(minute) type wheel r, causes the type wheel pawl lever to to be drawn back.
The lever a riding on the "tractrix curved teeth a', after being lifted onc
division of the peg wheel a², escapes the end of the tooth and falls on the base of
the next one. This allows the units type wheel lever spring to force its
lever wand pawl wo forward and thus carry the units (minute) type wheel »
forward one division. The above movement repeated nine times completes a
revolution of the units (minute) type wheel r and its cam u, which latter then drops
the cam lever', connected to the pawl lever w¹ of the tens (minute) type wheel ¹,
thus allowing the spring to push the said lever w¹ and pawl w forward, so as to
In a like manner the hours
move the tens (minute) type wheel one division.
type wheel is actuated by the tens (minute) type wheel at every half revolu
tion, the latter in its turn actuating the "a.m.'s " and "p.m.'s" type wheel ³
through the sleeve and cam at every revolution.
In order that the type wheels,,,, may not shoot past their respective
divisions the special locking device is now brought into action as hereinbefore
described. The hour and the "a.m.'s" and "p.m.'s" type wheels,³, are
operated and locked in the same manner as the tens (minute) type wheel "³,
the latter having two sets of numbers on its periphery it actuates the locking gear
and other parts of the hour type wheel every half. revolution, whereas the
"a m.'s" and "p.m.'s" type wheel is actuated only once every revolution of the
hour type wheel.
In order to render the speed of the type wheels ", 1, 2, 3, relative to each other
clear, it may be mentioned, that to one revolution of the slowest or "a.m.'s" and
p.m.'s" type wheel, the hour type wheel makes twelve revolutions, the
65

page_text: tens (minute) type wheel 72 revolutions; and units (minute) type wheel
864 revolutions.
The mechanical part of the apparatus is operated as follows:-
:-
The workman or other person using the apparatus for the purpose of recording
his time of arrival or departure writes or stamps his number or name as the case
may be, or when used in signal boxes, the signal-man records the particulars of the
passing trains, or when used on ship-board the man on watch records the passing of
other ships or points or other matter of interest, through the recording slot f¹ onto
the strip of paper below the same and afterwards imparts one turn to the
handle. The first half of the revolution of the main spindle b¹ removes the
impression made from underneath the slot f¹, to the stamp b, by means of
the feeding gear previously described, in the meantime positioning for action the
locking leg or arm 2 on the main intermediate lever and also registering the
number on the counter c. The second half of the revolution of the main spindle ¹
lowers the impression lever 7 together with its inking device and strip of paper d
thus receiving, the impression from the type wheels,,,, whilst the signal
bell e is rung in the meantime and the locking leg or arm finally lifted and all
parts brought into their normal or first position.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim, is-
