I, WILLIAM WHITEHEAD, of 160, Princess Road, 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 inking device for time checking and
recording apparatus and for type writing or type printing instruments which will
facilitate a more reliable automatic reversing of the inking ribbon than heretofore
has been the case..
To this end I employ in connection with the respective apparatus or instrument
two,spools, having each a pin or pins on the, inner side, one of which spools is fixed
upon, each end of a shaft passing through a tubular spindle mounted in the frame
of the apparatus or instrument. To one end of this tubular spindle is secured a
ratchet wheel and to the other end a similar ratchet wheel or disc of similar
diameter each baving a number of, holes in its side adapted, to engage alternately
the pin or pins of the aforesaid spools. A pawl under the influence of a spring is
adapted to engage and rotate the ratchet wheel on, the said.. spool shaft
intermittently.
In connection with the said spool is employed an inking ribbon passing over a
number of suitably positioned guide pulleys and adapted to be wound from one
spool onto the other alternately. In connection with each spool is employed a
rocking shaft having at one end a split lever through which the said inking ribbon
passes and at the other end a lever connected by means of a rod to a toggle-joint,
the lower end of which is jointed to a spring and the upper end being formed with
a fork adapted to engage a collar capable of sliding upon the tubular spindle and
connected to the spool shaft in the latter by means of a stud passing through a slot
in the said tubular spindle. The said inking ribbon near each end is furnished
with a projection which, when the ribbon is nearly wound off one spool; comes into
contact with and raises the split lever on the respective side. This causes the
position of the toggle-joint to be reversed through the medium of the respective
rocking shaft lever, rod and spring and the spool shaft to be moved longitudinally
in the tubular spindle so as to bring the spool unwound and out of gear, in gear
with the respective disc or wheel as the case may be and thereby reverse the travel
of the inking ribbon.

I, WILLIAM WHITEHEAD, of 160, Princess Road, 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 inking device for time checking and
recording apparatus and for type writing or type printing instruments which will
facilitate a more reliable automatic reversing of the inking ribbon than heretofore
bas been the case.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a cross section and Fig. 2 a plan of my improved type inking device.
In carrying out my invention and referring to the figures generally I employ in
connection with the apparatus or instrument, the type of which requires inking,
two spools a, a, mounted loosely upon the ends of a shaft b arranged inside a
tubular spindle e mounted in a frame d which may be that of the respective
apparatus or one specially employed for that purpose. In order to retain the
spools a, a, longitudinally in position upon the ends of the shaft b the same are
formed respectively with an annular groove b¹ and each spool a is furnished with a
hinged catch a adapted to engage in the groove 6. The spools a, a, on their inner
side are each furnished with a pin or pins a' and the respective ends of the tubular
spindle c with a disc e having holes el corresponding in position with the aforesaid
pins, and adapted to engage the pin or pins of each spool alternately.
The periphery of one or both of the discs e are formed with ratchet teeth in
connection with a pawl f, see Fig. 1, under the influence of a spring (not shown)
and adapted to engage in the ratchet teeth and thereby rotate the hollow spindle c
intermittently.
The pawl may be actuated from any movable part of the apparatus or
instrument to which the inking 'device is applied as may be found most
convenient.
g
In connection with the spools a, a, is employed an inking ribbon 9 passing over a
number of suitably positioned guide pulleys and adapted to be wound from one of
the said spools onto the other alternately. In connection with each spool a is
employed a rocking shaft i, i, say mounted on the frame d having at one end a split
lever through which the inking ribbon y passes and at the other end a lever
connected by means of a rod k to a toggle-joint 7, the lower end of which is jointed
to a spring m and the upper end being formed with a fork adapted to engage a
collar a capable of sliding upon the tubular spindle c and connected to the spool
shaft by means of a stud 62 passing through a slot c¹ in the tubular spindle c.
The inking ribbon g near each end is furnished with a projection which, when
the ribbon is nearly wound off one spool, comes into contact with and raises the
split lever on the respective side. This causes the position of the toggle-joint
to be reversed through the medium of the respective rocking shaft lever i², rod k
and spring m and the spool shaft b to be moved longitudinally in the tubular
spindle so as to bring the spool unwound and out of gear, in gear with the
respective disc or wheel e as the case may be and thereby reverse the travel of the
inking ribbon 9.

page_text: The collar n is formed with a flange at each end which are such a distance apart
from each other that the fork will not contact with the collar flange until the
moment when the toggle-joint I snaps past its centre thus effecting the coupling and
uncoupling instantaneously.
Having now particularly described and ascertained the nature of this iuven-
tion and in what manner the same is to be performed I declare that what I
claim, is-
e,
An automatic ink ribbon reversing device for time checking and recording
apparatus and for type writing or type printing instruments, consisting of two
spools a, a, loosely mounted upon a shaft b mounted inside a tubular spindle c
having at one end a ratchet wheel e and at the other a similar ratchet wheel or
disc the said spools and discs being adapted to couple and uncouple alternately
by means of a toggle-joint under the influence of a spring m and connected by
rods to the rocking shaft i, i, each having a split lever i through which the
inking ribbong passes, the latter carrying near each end a projection which
comes into contact with the said split levers on the respective side when the ribbon
is nearly unwound and causes, through the shaft and rods k, the toggle-joint I to
change its position, uncouple the full spool from the tubular spindle c and couple
the empty one with the same, substantially as set forth.

Improvements in Apparatus for Checking and Recording. Workmen's
Time, and for other similar purposes.
I, WILLIAM WHITEHEAD, of 160, Princess Road, Moss Side, Manchester, in
the County of Lancaster, Electrical Engineer, do hereby declare the nature of this
invention to be as follows:-
:-
This invention relates principally to improvements in that class of apparatus for
checking and recording workmen's time and for other similar purposes for which I
have obtained Letters Patent, No. 21083 dated Dec. 3rd 1891, and in which a time
stamp is employed, in connection with an intermittently moved strip of paper adapted
to receive the impression of the stamp and the number or name of the workman, or
other particulars, the type wheels of which stamp being operated by a secondary
clock-work controlled by a primary clock or by a primary clock direct, whilst the
stamp itself is moved against and from the paper strip through suitable means by the
person using the apparatus..
The present invention has for its object to simplify the' construction and render
more positive and reliable the working of the various parts constituting the said
apparatus and embodies, firstly, improved type wheels and mechanism for actuating
the same; secondly, improved means for moving the paper strip; and lastly means for
controlling the action of the secondary clock.
According to this invention the numbers and letters on the type wheels are not
inverted as heretofore, but printed through the paper, the inking ribbon being, above*
the said paper strip, and the type wheels raised against the latter, or the said ribbon
may be dispensed with and the numbers or letters embossed through. This arrange
ment enables me to give the paper strip a straight course through the apparatus and
the printed or embossed matter to face the operator. The said type wheels comprise a
minute units wheel with numbers 0-9, a minute tens wheel with numbers 1-5 twice
and two blank spaces, an hour wheel with numbers 1-12 and lastly a meridian wheel
with six.a.m.'s occupying one half and six p.m.'s occupying the other half of the
periphery. The said type wheels are positioned in successive order, the minute units
wheel being fixed upon a sleeve and the others mounted loosely thereon and the said
sleeve loosely upon a spindle carried by the frame of the stamp. The minute units
wheel has internally ten V recesses and secured to its side concentric with the said
recesses, a ratchet wheel having ten teeth. Upon the sleeve of the minute units wheel
is mounted loosely a four armed lever carrying a pawl under the influence of a spring
ID 017

page_text: which engages the said ratchet wheel and also a roller acting upon a locking lever to
be described, which controls the latter. On the side of the minute units wheel near
its periphery is a pin furnished with a roller which engages a ratchet wheel having
twelve teeth, fixed upon a governing shaft positioned below the type wheels and
mounted in the frame which carries the type wheels. Upon this shaft is also
fixed a toothed wheel gearing into a wheel of equal diameter fixed to one side of
the minute tens wheel and a cam disc having two recesses and two arms each
furnished with a roller which act upon pins carried by a disc fixed into a cavity on
the side of the hour type wheel and having on its periphery twelve ✓ recesses and
twelve pins or teeth. Upon the said governing shaft is fixed a second disc having one
recess and one arm furnished with a roller which act upon twelve recesses and twelve
pins of a disc fixed in a cavity to the side of the meridian wheel for the purpose of
governing it. A third disc fixed upon the governing shaft has twelve V recesses
which serve to lock the whole number of type wheels in position each time a change
takes place. In connection with the last nained V recessed disc and the minute units
wheel is employed to rock upon a stud a locking lever each end of which is furnished
with a roller, one being adapted to drop into the V recesses of the said third disc and
the other to ride upon a disc fixed to the side of the minute units wheel having
one recess only on its periphery into which the said roller drops the moment a
change takes place in the position of the type wheels allowing the other roller to
rise out of the V recess of the said third disc. Opposite to the said locking lever are
employed to rock upon another stud three other locking levers one of which (the
minute units wheel lever) carries at its free end one roller and the others (the hour
and meridian wheel levers) having two rollers each, one being adapted to engage
the recesses in the side of its respective wheel and the other to ride upon the
periphery of the governing shaft disc so as to keep the type wheels in their relative
position.
If desirable the type wheel described may be increased in diameter so as to permit
of having the whole of the days of a month on the periphery, in which case the
numbers on the other wheels described would be doubled.
The paper strip is drawn by means of a pair of rollers from a roll mounted in the
frame of the apparatus passing in a straight line over a recording plate and between
a padded impression bar and the type wheels, onto a filling roller kept in contact by a
spring with the said drawing rollers. One of the latter, the pressure roller, is
mounted eccentrically and under the control of a lever whilst the other is covered with
rubber and actuated by a ratchet wheel lever and pawl, another pawl being employed
to prevent the said roller moving backwards. The said pawl lever is connected by a
rod to a crank pin carried by one of the cams fixed upon the main shaft and which I
raise and lower the type wheels.
Motion is imparted to the minute units type wheel from the magnet by means of
a lever, one end of which is jointed to an arm on the said magnet and the other end
to the main lever of the secondary clock. The latter consists of a minute wheel
with sixty teeth fixed upon the minute hand spindle. The main lever is adapted
to rock upon a stud and is furnished at one side of its fulcrum with a pawl under
the influence of a spring, which pawl engages the said minute wheel and is limited
in its stroke by. abuting against a bar and thus prevented from overshooting. The
said lever on the other side of its fulcrum is placed under the influence of a spring
which brings it back to its normal position. On one of the frame studs of the
secondary clock is employed loosely a pawl riding on the minute wheel and having
a stud on its side upon which rests the spring end of the said main lever which
when upon it retains the pawl in the teeth of the said wheel and thus prevents the
same from unduly rotating. The said secondary clock comprises other wheels and
pinions which convert the time from minutes to hours similar as in an ordinary
clock.

page_text: Improvements in Apparatus for Checking and Recording Workmen's
Time, and for other similar purposes.
I, WILLIAM WHITEHEAD, of 160, Princess Road, 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 :-
This invention relates principally to improvements in that class of apparatus for
checking and recording workmen's time and for other similar purposes for which
I have obtained Letters Patent No. 21083-dated Dec. 3rd 1891, and in which
a time stamp is employed in connection with an intermittently moved strip of
paper adapted to receive the impression of the time stamp and the number or name
of the workman, or other particulars, the type wheels of which stamp are operated
by a secondary clockwork controlled by a primary clock or by a primary clock
direct.
The present invention has for its object to simplify the construction and render
more positive and reliable the working of the various parts constituting the said
apparatus and embodies, firstly, improved type wheels and mechanism for actuating
the same; secondly, means for moving the paper strip in a straight line or nearly
so and facilitating the filing thereof; and, lastly, means for controlling the action
of the secondary clock.
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.
Figs. 1 & 2, Sheet I, are respectively a side view and a front view partly in
section, and Fig. 3 a back view with door removed of a complete apparatus for
checking and recording workmen's time and for other similar purposes. Figs. 4
& 5 are respectively a side view and plan of a portion of the secondary clock,
Fig. 6 is an end view of the time stamp, Fig. 7 shows the left side of the hour
type wheel, Fig. 8 the left side of the minute tens wheel, Fig. 9 the right side of
the minute units wheel, Fig. 10 the right side of the a.m. and p.m. wheel in con-
nection with the respective discs and wheels, Fig. 11 shows the left side of the
minute units wheel.
Figs. 12 & 13, Sheet II, are side views, Fig. 14 a plan, Fig. 15 a longitudinal
section at line A-B of Fig. 14, and Fig. 16 an end view of a portion of Fig. 12.
of the time stamp and accessory mechanism.
In carrying out my invention and referring to Figs. 1, 2 & 3, Sheet I, a is the
casing of the apparatus formed with a recording slot a¹ and containing the
secondary clock, the counter c, the time stamp d its accessory mechanism and
the signal belle, is the main shaft of the apparatus furnished with a handle 1
by means of which and suitable connections hereinafter described, the time stamp d
is raised and lowered, the counter and signal bell care operated, and the inking
ribbone and the paper strip moved intermittently. The counter c serves to
indicate the number of turns of the handle f¹ and the bell c as a check against
improper use of the apparatus, giving a signal on every revolution of the main
shaft by a pin f* thereon depressing a spring blade having attached the bell
hammer, whilst a pawl and ratchet prevents the handle 7 being turned in
the wrong direction and a spring stop e confines its movement to one revolution.
The secondary clock 6 is controlled by a primary clock (not shown) which may
be that of a works or other place as the case may be.
According to this invention the numbers and letters on the stamp d, i.e. on the
type wheels d', d, d³, d', see Fig. 6, are not inverted as heretofore but formed to

page_text: The
print through the paper strip g, the inking ribbon e being above the paper strip 9,
see Fig. 15, Sheet II, and the said type wheels raised against the latter, or the
ribbon e may be dispensed with and the numbers or letters embossed through the
paper strip g. This arrangement enables me to give the paper strip g a straight
course through the apparatus and the printed or embossed matter to face the
operator. The inking ribbon e when employed is wound from one spool onto
another by means of a pawl fa attached to one of the cam levers f and
engaging a ratchet wheel fixed upon the shaft which carries also the
spools, the reversing of the ribbon e being effected by throwing the pawl f
out of gear and winding the ribbon from the full spool onto the empty one.
said type wheels comprise, see Figs. 6-11, a minute units wheel d* with
numbers 0-9, a miinute tens wheel 2 with numbers 1-5 twice and two blank
spaces, an hour wheel with numbers 1-12, and lastly a meridian wheel d' with
six a.m.'s occupying one half and 6 p.m.'s occupying the other half of the
periphery. The said type wheels are positioned in successive order, the minute
units wheel d³ being fixed upon a sleeve h and the others d', d², d, mounted loosely
thereon and the sleeve loosely upon a spindle h' carried by the stamp frame i.
The latter is formed of two cross shaped pieces suitably tied together and having
projections adapted to slide in slots formed in the outer frame i and pivots i
engaging the eccentrics levers by means of which the stamp is raised and
lowered. The minute units wheel has internally ten V recesses k, see Fig. 9,
and secured to its side concentric with the said recesses, a ratchet wheel having
ten teeth. Upon the sleeve his mounted loosely a four armed lever carrying a
pawl under the influence of a spring which pawl engages the ratchet wheel ' and
also a roller acting upon a locking lever 83 to be described, which controls the
latter. On the side of the minute units wheel near its periphery is a roller
which engages a ratchet wheel n having twelve teeth and fixed upon a governing
shaft positioned below the said type wheels and mounted in the stamp frame i.
Upon this shaft is also fixed a toothed wheel o, see Fig. 8, gearing into a wheel o¹
of equal diameter fixed to one side of the minute tens wheel d² and a cam disc p,
see Fig. 7, having two recesses p' and two arms p' each furnished with a roller på
which act upon twelve pins or teeth q carried by a disc q' fixed into a cavity on
the side of the hour type wheel d' and having on its periphery twelve ✓ recesses q³.
Upon the governing shaft n' is fixed a second disc p, see Fig. 10, having one
recess and one arm p³ furnished with a roller p³ which act in conjunction with
twelve recesses q' and twelve pins or teeth q on the disc q¹ fixed in a cavity to
the side of the meridian wheel d for the purpose of governing it. A third disc
fixed upon the governing shaft n' bas twelve V recesses which serve to lock
the whole of the said type wheels in position each time a change takes place. In
connection with the disc r and the minute units wheel d³ is employed to rock
upon a stud n a locking levers each end of which is furnished with a
rollers, respectively, see also Figs. 11 & 15, s being adapted to drop
into the V recesses of the disc r and the other s³ to ride upon a disc p fixed to the
side of the minute units wheel d³ having one recess p¹ only on its periphery into
which the roller drops the moment a change takes place in the position of the
type wheels allowing the other roller s¹ to rise out of the V recess of the disc r.
Opposite to the locking levers are employed to rock upon another stud n³ three
other locking levers 3, 6, 57, one of which (the minute units wheel lever s³) carries
at its free end one roller s* and the others (the hour and meridian wheel levers s³, 87,)
two rollers s, each, one being adapted to engage the V recesses q³ in the side of
its respective type wheel and the other to ride upon the periphery of the governing
shaft disc p so as to keep the type wheels locked in their relative position.
6
If desirable the type wheels described may be increased in diameter so as to permit
of having the whole of the days of a month on the periphery, in which case the
numbers on the other wheels described would be doubled as will be readily
understood.
The paper strip g, see Fig. 15, Sheet II, is drawn by means of a pair of

page_text: rollers g¹, g³, from a roll y³ mounted in the frame of the apparatus passing in a
straight line over a recording plate a' and between a padded impression bar a³ and
the time stamp d onto a filing roller * mounted in a lever g kept in contact by a
spring with the drawing roller g'. The pressure roller g', is mounted eccentrically
and under the control of a lever gs, see Figs. 12. & 13, whilst the other g² is covered
with rubber and actuated by a ratchet wheel 9', see Fig. 13, and a pawl 98 carried
by a lever 9º a stationary pawl 910 being employed to prevent the roller g³ moving
backwards. The pawl lever g is connected by a rod o" to a crank pin carried by
one of the cams,, fixed upon the main shaft f and which raise and lower the
time stamp d.
Motion is imparted to the minute units type wheel from the magnet t, see
Figs. 9 & 15, by means of a lever ', one end of which is fixed to the armature {*
and the other end by the link t³ to the four armed lever l.

The secondary clock consists of a minute wheel with sixty teeth fixed upon
the minute hand spindle (not shown). The main lever is adapted to rock upon a
stud and is furnished at one side of its fulcrum with a pawl 6 under the influence
of a spring, which pawl engages the minute wheel 6 and is limited in its stroke by
abuting against a bar and thus prevented from overshooting. The lever 6' on
the other side of its fulcrum is placed under the influence of a spring & which
brings it back to its normal position. On one of the frame studs of the secondary
clock is employed loosely a pawl 68 riding on the minute wheel b' and having a
stad 6° on its side upon which rests the spring end of the main lever 6 which when
upon it retains the pawl 64 in the teeth of the wheel 6' and thus prevents the same
from unduly rotating backwards. To ensure the pawl 6 engaging the teeth of the
minute wheel 6' when required, a pin 11 is fixed on the spring end of the pawl
lever 62, which at the end of the downward movement of the pawl & comes into
contact with an extension 60 on the pawl 68 thus making its action certain. The said
secondary clock comprises other wheels and pinions which convert the time from
minutes to hours as in an ordinary clock.
The counter c is operated by means of a rocking lever wo pivoted to the outer
frame one end of which bears against the cam leverf through the action of a
spring in the counter and the other end being connected to the counter c by means
of a rod w', see Figs. 1 & 12. For the purpose of indicating when the roll of paper
has been nearly exhausted springs m, m³, are so placed that on the roll being nearly
exhausted an extension m2 on the tension lever m³ comes into contact with the
spring m, and brings the same against the spring m' thus closing the circuit and
ringing an electric bell suitably placed.
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 a' onto
the strip of paper 9 below the same and afterwards imparts one turn to the
handle.
The first half of the revolution of the main shaft removes the particulars from
underneath the slot a¹ to the stamp d, by means of the feeding gear previously
described, in the meantime positioning for action the upper ends of the locking
lever, which is furnished with an anti-friction bowl, on the intermediate lever
also moving the rocking lever w and registering the number on the counter c.
The second half of the revolution of the main shaft fraises the stamp d by the
eccentrics factuating the levers and causes an impression, rings the signal
bell c and finally unlocks the intermediate lever o and brings all moving parts to
their normal position.
The action of the type wheels in conjunction with the secondary clock is as
follows:-
In the primary clock (not shown) is an electric circuit closer. The electric circuit

page_text: from a battery or other electric source is closed by the circuit closer of the primary
-clock at predetermined intervals, in the present instance every minute. The current
passing round the electro-magnet t attracts the armature and the connections
between the same and the four armed lever of the minute units wheel d³, sets the
pawl back in position, as shown in Fig. 9, against the tension of spring through
the intermediate lever, shaft v, arm ¹, and link *, the backlash of the pawl l
being for the purpose of admitting of the unlocking of the minute units wheel
locking levers. This action has moved the secondary clock one minute. After the
circuit has been broken by the primary clock the spring is free to act. Should
however the apparatus be in use at the time of the current passing the following
locking device will come into operation:-The lever secured to the cam * rotates
(as indicated by dotted lines and arrow, Fig. 12,) from underneath the curved
arm, the free end of which is bent inwardly and which is secured upon the
rocking shaft placed under the influence of a straight spring v. The action of
the spring then causes the shaft to partially turn and place the free end of the
lever in position underneath the back end of the intermediate lever to prevent
it moving downward until the stamping operation is completed. After completion
of the same, the lever is moved from underneath the intermediate lever e* and the
latter set free to act, owing to the lever 10 coming into contact with and moving
the lever outwards and the latter turning back the shaft vs. On the minute units
wheel d³ completing one revolution the roller 13 comes in contact with the ratchet
wheel n on the governing shaft n' carrying it one division, and thus the minute
tens wheel d² through the spur wheels o, o', one division at the same time the rocking
lever rollers which rides on the disc p, see Fig. 11, falls into the recess pl which
allows the other roller s at the other end of the levers to leave the recess r¹ in
the disc r.
Every sixth movement of the minute tens wheel the hour wheel d¹ is moved
one division by one of the arms on the disc p coming into contact with one of
the pins 9 on the hour wheel at the same time the roller on the lever ' drops
into recess pl on the disc p and a precisely similar roller s on the opposite side of
the lever drops out of one of the V recesses q³ thus allowing the hour wheel to
move one division whilst otherwise the hour wheel a' is locked in position. The
meridian wheel a' is moved in an exactly similar manner except that it moves only
one division in two hours, its disc p having only one arm på and one recess pl.
The time stamp and and its mechanism described in connection with a clock and
suitable casing can also be used for stamping the time of arrival and delivery of
documents and the like onto the same.
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—
