PROVISIONAL SPECIFICATION.
Improvements in Time Stamps.
I PETER GLORGE GIROUD, of 276 Washington Avenue, Woodside, Newark,
in the County of Essex and State of New Jersey, United States of America,
Mechanical Expert, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in time stamps, in which type wheels
indicating the time of day, of the month, and of the year, are actuated at suitable
intervals, to enable an impression to be taken at any time, by inserting the
material to receive the impression beneath a reciprocating platen and the type
wheels.
The casing in which the type-wheels and their immediate operating mechanism
are mounted, is provided with a cover, which may be swung back, or removed, nt
pleasure, the cover having an opening therethrough, for the purpose of receiving
the impression from the type wheels. The reciprocating platen is mounted in a
standard upsing from the casing, to which it is rigidly secured. The platen is
provided with a retiacting spring, and the standard is provided with a yielding
cushion, which may be of india rubber, which cushion foi ms an abutment for the
neck of the platen, when it returns from its advanced stroke, under the tension of
the sping. The cushion serves to relieve the apparatus from a sharp jar, which
has been found objectionable, because of its tendency to disturb the time or motor
nechanism.
The type-wheels for denoting the minute, hour, day of the month, month, and
year, are mounted on axial alignment, so as to bring their peripheries in substan-
tially the same plane, at then points nearest or directly underneath the platen.
The several type-wheels are mounted upon a spindle carried by a framework.
The type-wheel which indicates the minute, has a gear wheel fixed to rotate
therewith, and intermcshing with a dive wheel caried by a shaft which, by
means of a crank arm, has imparted to it a step-by-step movement at inter vals of
one minute, by means of a drive wheel actuated by a motor. It is intended that
the dive wheel shaft shall complete a revolution once every hout, and it is made
to move the hour and meridian wheels one step at the completion of each revolu-
tion, in the present instance, by means of a mutilated pinion, the teeth of which
engage the teeth on the end of a pivotted aim carried by the framework. This
pivotted aim has fixed, to rock therewith, an operating level, which carries at its
free end a peculiar shaped pawl, which, for convenience, I call a deci-foot. The
pivotted aim, and the operating lever fixed to rock therewith, are both noimally
held in an advanced position, by means of an actuating spring attached at one end
to a support on the fiame-work, and at its opposite end to an arm projecting from
the pivotted arm before mentioned on the opposite side of its pivotal support.
The deer-foot carried by the pivoted arm is in the nature of a t-armed angle
lever pivoted to the free end of the operating lever before referred to.
One arm
of the deer foot projects upwardly into position to engage one of the twenty-four
equidistant teeth or abutments on the hour wheel. Another aim of the deci-foot,
which may extend in a duection from the pivotal point opposite that on which the
first arm extends, is provided with a stop pin adapted to enter a slot to in the
pivoted arm, and, upon reaching the bottoni of the slot, to prevent the deci-foot

page_text: from rocking further in one direction. A third aim of the deer-fout extends in a
direction from the pivotal point of the lever intermediate of the directions of the
other two aims, and is provided at its free end with a flat face, for the purpose of
engaging a pin projecting laterally from the free end of a locking lever, which is
pivoted on a suitable support carried by the framework, and is held normally in
engagement with the hour wheel by means of a spring. The operating face of
this lever is provided with a blunt tooth, the face of which tooth is bevelled so as
to give the holding end of the blunt tooth a pitch wardly towards the axis of the
hour wheel, beyond the opposite end of the tooth. The tooth is intended to
form an easy, but close fit between each two successive abutments on the hour
wheel, and its inward movement is limited by a shoulder adjacent to the end of
the tooth, which-shoulder is intended to come in contact with the outer end of the
abutment, against which the holding end of the tooth presses, when the lever is in
locking adjustment.
The operation of the deer-foot, the locking lever, and their actuating
mechanism, is as follows. As the minute wheel approaches the end of the hour,
the teeth on the mutilated pinion engage the teeth on the pivotted arm, and
gradually rock the said aim, and hence the operating level, back against the
tension of the spring before mentioned Such movement of the lever bings the
nose on the end of the first aim on the deer-foot against the preceding abutment of
the hour wheel, and thereby rocks the deer-foot on its pivotal support, the pin
passing towards, or out of the mouth of the slot in the level. As this lever
approaches the limit of its backward movement, the aim of the deer-foot disengages
the pieceding abutment, and the deer-foot is thrown into its normal position by
means of a spring fixed to the operating lever, and resting with its free end on a
pin on the second aim of the deer-foot. At the moment the hour is completed, the
gear on the mutilated pinion disengages the pivotted urm, and permits the operating
level to 10k forward under the tension of its spring. In moving forward, the end
of the third aim of the dec foot strikes the pin on the locking lever above
mentioned, before the end of the first arm of the dec-foot strikes the abutment on
the hour wheel, and before escaping from the pin, swings the locking lever
sufficiently to withdraw the tooth thereof from between two abutments of the hou
wheel, thereby leaving the said wheel free to be rotated. At the very moment
the tooth releases the hour wheel, the first arm of the deer-foot engages the
abutment, and forces the hour wheel around, At this same moment, the end of the
third arm of the deer-foot escapes from the pin, and the locking lever presses back
again towards the abutments on the hour wheel. As the bevelled face of the tooth
rides along on the outer end or face of the abutment, the forward or holding
end of the tooth will gradually creep inward towards the axis of the wheel, so that
when the next successive abutment comes to a point in radial alignment with the
holding end of the tooth, the holding end of said tooth will overlap the said
abutment to an extent sufficient to ensure a positive stop of the houi wheel at
that point.
The median wleel is fixed to rotate with the hour wheel, so that the
bуmbols A and г.. will fall opposite the respective hours from one to twelve,
counting from midnight until noon, and from one to twelve, counting from noon to
midnight, respectively. As the twenty-four hours pass, a day wheel is moved a
single step by means of an operating lever and deer-foot, quite similar to the
operating lever just described, and the deer-foot carited thereby, and is arrested by
a locking lever quite similar to the lever controlled by the deer-foot, as already
explained The operating level corresponding is, however, in this instance, tlu own
back against the tension of its actuating spring by means of an arm provided with
an extended bearing face at its free end, which ince is engaged by a holler on the
hou o mendian wheel, in the present instance, carried by the hour wheel, and so
located with respect to the aim, that, as the wheels approach the end of the
twenty-four hour, the lever will be 1ocked back against the tension of its actuating
spring, to bring the deer-foot to position to release the locking-lever, and also to

page_text: force the day wheel one step forward, and at the moment the twenty-four hours
are completed the roller will escape from the face of the lever, permitting it, and
hence the operating lever, to advance under the tension of the actuating spring, and
force the day wheel forward one step. The number of equidistant abutments on
the day wheel will be thirty-one.
As the day wheel completes its thirty-one steps, it serves to move the month
wheel one step in a manner quite similar to that in which the hour and meridian
wheels operate the day wheel.
The abutments on the month wheel are twenty-four in number, at equal
distances apart, a sufficient number to correspond to the succession of twelve mouths
for two consecutive years.
The year wheel may be set by hand at the beginning of each successive year, and
it is held in position by means of a notched disc provided with twelve equidistant
notches in its periphery, and fixed to rotate with the year wheel, a spring
actuated arm being provided with a V shaped nose adapted to enter one of the
notches. To set the year wheel, the arm is lifted to release the disc, and the disc
is then rotated a distance between two notches, and the arm again permitted to fall
into engagement with it.
The operation of the stamp might go on, as thus described, without error,
provided that each of the months contained thirty-one days. As this is not true,
it is necessary that there should be provided some means for correcting the crior
by advancing the day wheel one or more steps at the end of such mouths as have
less than thirty-one days, in order to complete the thirty-one, and register the
new month at the proper time. 1 have provided for this by a cıank aim secured to
rock with an operating lever, and provided with a laterally projecting operating
pin at its fiee end. In position to engage this pin, I locate a rotary snail cam
fixed to a spindle which projects through the casing, and is provided with some
suitable means for turning By rotating the snail cam one revolution, the crank
am is lifted, thereby throwing back the operating lever, and is then released,
permitting the operating leve to advance and set the day wheel forward one
step. A second evolution of the snail cam will set the day wheel forward a second
step, and so on
In connection with the printing mechanism as her einabove described, I provide
an inking device, consisting of an inking bbon engaged with a pair of spools, one
at each end of the ribbon, the said spools being mounted in casings which have a
emovable engagement with the interior of the casing The casings may consist of
back plates, each provided at one end with an oblique slot for receiving the shauk
of a headed stud on screw set in the side of the casing, the opposite end of the back
plate being provided with a projecting hook, which is adapted to enter a socket in
the corner of the casing. From the back plate, ends project at right angles to the
back plate, and these scive as supporters to the spool spindle, leaving the front
open for the passage of the ribbon, which passes from the spool over a guide 1oller
mounted in the said ends, at their upper front portions
By elevating on removing the cover of the main casing, the ibbon casings may
(one or both of them) be removed at pleasure, and another set similar thereto be
inserted in their places, while the abbon on those removed is being changed on
re-inked. The spools are arranged to rotate either duection at pleasure,
sufficient tension being applied thereto, to hold the 1ibbon smooth, by means of
springs which sound the spool spindle, inde confined between pins on the
spindle and the end of the casing, and which tend to draw a shoulder or disc on
the spindle against the end of the spool. The spool spindles are provided with
thumb attachments which project outside the casing for purposes of moving the
ribbon along at emtable intervals as the stamp is used.
The casing in which the parts of the motor are mounted, cousists of front
plate and rear plate, and tie pins or girders for securing the fiont and reu plates
together at a suitable distance apart.
The spring or actuating the motor train is housed within a drum suitably

page_text: mounted between the front and rear plates, and provided with a diving gear wheel
fixed to rotate therewith.
The actuating spring for the time train is housed within another rotary drum,
suitably mounted between the front and rear plates, and provided with a diving
gear wheel fixed to rotate therewith.
Intermediate of the gear wheels, I mount a spindle extending through, from in
front of the front plate to the rear of the rear plate, and provided on its ical end
with a squared portion, for the purpose of attaching thereto a key for turning it.
Adjacent to the squared portion, the spindle provided with a collar or shoulder,
for the purpose of exerting a pressure upon the spindle, to slide it longitudinally
towards the front To the front end of the spindle there is secured a power-
transmitting wheel, provided with an annular series of teeth on the edge of the
periphery, and with a crank pm projecting from its from face The spindle is
loosely mounted in both rotary and longitudinal adjustment within a sleeve, which
in tuin is loosely mounted in suitable bearings in the front and rear plates, and
which sleeve has fixed to its front, intermediate of the transmitting wheel and the
front plate, an arm, the free end of which is held normally in engagement with the
teeth on the transmitting wheel, by the pressure of a spring interposed between
the collar or shoulder on the spindle and the rear end of the sleeve Fixed to
rotate with the sleeve, is a pinion provided with a toothed wheel fixed to rotate
with the pinion. There is also loosely mounted on the sleeve a pinion having fixed
to rotate therewith a toothed wheel.
The drive wheel of the motor gear engages the pinion fixed to rotate with the
sleeve, and tends to rotate it, and hence the arm attached thereto, and,-when
the latter is in its normal engagement with the power transmitting wheel, to
advance the same The movement of the pinion, under the pressure of the duve
wbrel is permitted when a stop wheel is released by tip mechanism. Motion 18
transmitted to the said stop wheel from the pinion engaging with the drive wheel,
by means of a pinion fixed to 1otate with the stop wheel in engagement with a
toothed wheel having a pinion fixed to rotate therewith, the pinion, being
engaged with the toothed wheel fixed to rotate with the pinion engaging with the
dive wheel.
The dive wheel of the time tram transmits power, through a series of toothed
wheels and pinions, to an escapement wheel.
In connection with this gear is a lantern pinion, the bars of which serve to
actuate the trip lever for releasing the stop wheel her anbefore referred to
The trip ever is seemed to a tocking shalt, suitably mounted in front and rear
frames. One aim of the lever has its end extended to engagement with bus of
the lantern pinion, while the other aim of the lever extends to engagement with
the stop wheel The stop wheel is provided with a pin projecting from its side,
and the second arm of the tip lever is provided with two abutments located at the
side of its free end, and lapping past cach other at then fiee edges, and spaced
apart sufficiently to permit the stop wheel pin to pass between them The shaft
to which the tup lever is secured, has fixed thereto an aim, to the free end of
which one end of a spring is secured, the opposite end of said spring being secured
to a suitable support on the front plate The tension of the spring is such as to
tend to rotate the shaft in a ducction to hold the free end of the second arm of
the tup lever as far as possible towards the centre of the
stop wheel At the same
time, the free end of the fist aim of the tip lever is so located with respect to
the bais on the lantern pinion, that before the bar has passed the free end of the
said arn, it will have rocked the trip lever sufficiently to permit the pin on the stop
wheel to escape under the abutment on the second arm, and in contact with the
second abutment on the trip lever. In this position, the stop wheel will be held
until the trip lever is.rocked in a direction to permit the pin of the stop wheel
to escape over the second abutment on the trip level, the stop wheel will be
thereby permitted to make nearly a complete revolution, its arrest being caused by
the engagement of the pin the con with the fist abutment, which, at this moment,

page_text: is drawn down to its path by the rocking of the trip over under the Dsion or
its spring.
The bars on the lantern pinion may be located at such intervals apart, as to
operate the trip lever every minute, half minute, quarter minute, or at any other
desired interval of time, and it will therefore follow that the rotation of the stop
wheel will take place at such predetermined intervals of tune, and hence, in the
manner herein before described, the power transmitting wheel will, at such intervals
of time, act through its crank pm upon the typewheels and time indicating hands
under its control.
The shaft to transmitting motion from the transmitting wheel has an arm
thereon provided with a slot for the reception of the crank pin on the transmitting
wheel, the relation of the said wheel to the said arm being such, that the wheel
may he thrown out of engagement with the teeth of its engaging arm without
disturbing the engagement of the crank pin with the slot in the arm just
mentioned
By mounting the spindle to which the power-transmitting wheel is secured, so as
to permit it to be moved longitudinally against the tension of its sping, out of the
teeth of its engaging aim, I provide for rotating said power transmitting wheel at
pleasure, so long as it is out of engagement with the said aim, and thereby
operating the type wheels and time-indicating hands of the stamp, or whatever
ocher mechanism may be driven by said power transmitting wheel, to set it into
the desed position, without many manner disturbing either the time of motor
tiains o gear, and, at the same time, utilizing the said spindle for purposes of
mounting the power-transmitting wheel while in normal engagement with the motor
and mechanism. The rotary movement of the stop wheel is prompt and tapid, so
that the power transmitting wheel, and hence any mechanism that may be operated
thereby, will remain at test, with the exception of buet moments, at such intervals
as may be determined upon, since no matter how rapid the stop wheel rotates, it
will find the abutment down in position to arrest it, for the reason that the abut-
ment has been drawn down into the path of the pin of the stop wheel simultaneously
with the passage of the pin over the abutment.
114
The attachment for advancing the tune card, so that the workman's time of
aruval and departure may be recorded, is constructed and arranged as follows
The fixed or immovable portion of the attachment is removably secured to the
top of the casing A plate is formed integial with, or secured to the fixed piece,
at or near one end thereof, in position to form an extension of the top of the casing
when the fixed piece is secured thereon
The fixed piece is further provided with upper and lower longitudinal grooves,
and an elongated slot is cut though the wall, between the upper and lower grooves,
for the purpose which will be hereafter described.
The time card holder is mounted to slide upon the fixed piece in the following
manici A tongue extends along the bottom of the holder, and enters a longi-
tudinal groove o recess in the fixed piece. This tongue fits within the groove, so
as to allow the holder to have a fice sliding movement along the fixed piece.
A flat spring is fitted within the groove of the fixed piece, and is secured to the
caid holder by means of a suitable screw, which passes through the elongated slot
before mentioned, and enters the tongue. By this means, the card holder is allowed
a limited sliding movement along the fixed piece.
The holder is provided with a suitable handle at oue end, which is adapte to be
grasped by the attendant for sliding the holder along the fixed piece. For forming
a support for the time card, I extend the bottom of the holder laterally at its
opposite ende, and connect the outer ends of the said laterally extended portions
by means of a suitable connecting bar. These laterally extended ends are provided
with suitable stops or abutments, between which the card is inserted into position
to be stamped.
For yieldingly holding the card in position upon the holder, I provide suitable
prings, which are secured at their inner ends to the mam portion of the holder,

page_text: and their outer ends rest upon the laterally extended portions of the holder. The
main portion of the holder, the laterally extended portions, and the connecting
portion or bai, form an open frame-work, which will receive the time card, and
hold it against displacement in any direction, so as to allow the time of arrival or
departme to be printed at the proper place upon the card. The outer edge of the
connecting bai is turned downwardly, so as to overlap the front of the top of the
casing. This downwardly extended lip is reinforced by a suitable we or rod,
This lip will prevent the edge of the card from catching, as it is inserted into the
holder.
For advancing the holder regular distances along the fixed piece, for permitting
the times of arrival and departure of the workman, and for locking it in each of
its adjustments, I provide the following mechanism :-A settes of holes on recesses
me formed along the top of the sliding holder, and are spaced at equal distances
apart There are preferably twenty-four of said holes o recesses, so that the
sliding holder may be advanced the distance of four holes on recesses each working
day for a week. A vertically movable spring-actuated lever is mounted in a suitable
laterally swinging bearing piece, which beating piece is pivotted to a laterally
extended lug of the fixed piece, by means of a suitable screw The front aim of
the lever is provided with a downwardly-extended pin adapted to enter the several
openings o recesses on the holder, when the said front aim is in its normally
lowered position. This pin is held against displacement within the said openings
or reces-es, by means of a coiled spring, which engages a tear aim of thumb piece
at its upper end, and the laterally swinging bearing piece at its lower end
It will
thus be seen, that as the thumb piece of the lever is depressed, the downwardly
extended pin will be released from engagement with the recesses in the sliding
holder, and the said holder will be free to slide along the fixed piece.
It
The lever is yieldingly held in a position at night angles to the sliding holder
by means of a coiled sping, which preferably surrounds the pivot screw of the
beaung piece, one end of the said spring engaging the laterally swinging bearing
piece, and its other end engaging the laterally extended lug of the fixed piece
will thus be seen that the sliding holder may be slid along the fixed piece a short
distance, without cleastug the lever from its engagement with said holder, the
Said lever being free to swing laterally in its beaung. The distance of its said
limited movement of the holder, is preferably the distance between two of the
recesses, and is positively regulated by means of two stops.
46
In operation, supposing that the times of arrival and departure have been
printed upon the card down to Fiday, the lever is caused to engage the proper
opening or recess, so as to bring the space on the card opposite the first word "In"
in the Funday" division, over the type wheels of the time stamp, the time card
is then inserted into its position in the holder, with its face down, and the plunger
18 then depressed, causing the type wheels to print the required time in said space,
opposite the first word "In." As the workman goes out at noon, the lever has
been raised, and the holder been advanced one notch, so that the space to be
printed opposite the first word "Out," in the "Friday" space, is in position to have
the time stamped therein This process is repeated as often as the workman arrives
and departs from work As the different workmen are going and coming at about
the same time during the noon hour, the feature of my device of being able to
slide the holder along the fixed piece the distance between two recesses, the attendant
can leave the holder as it is, to stamp the tune of a workman going out, and can
slide the holder forward, to stamp the time of a workman coming in, without
operating the lever.

1 PETER GEORGE GIROUD of 276 Washington Avenue, Woodside, Newark
in the County of Essex and State of New Jersey, United States of America,
Mechanical Expert, 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 :—
My invention relates to improvements in time stamps in which type-wheels
indicating the time of the day, of the month, and of the year, are actuated at
suitable intervals, to enable an impression to be taken at any time, by inserting the
material to receive the impression beneath a reciprocating platen and the type
wheels.

The casing in which the type wheels and their immediate operating mechanism
are mounted (see Figs. 1 to 8 melusive) is denoted by A, and is provided with a
cover a, which may be swung back or removed at pleasure, the cover having an

page_text: opening a therethrough, for the purpose of receiving the impression from the type
wheels. The reciprocating platen is denoted by B, and is mounted in a standard A',
upusing from the ensing A, to which it is rigidly secured. The platen B is
provided with a retracting spring b, and the standard A' is provided with a
yielding cushion b¹, which may be of india rubber, which cushion forms an abutment
for the neck of the platen B, when it returns from its advanced stroke under the
tension of the spring b The cushion 6 serves to relieve the apparatus from a
sharp jar, which has been found objectionable, because of its tendency to disturb
the time or motor mechanism.
The type wheels for deuoting the minute, hour, day of the month, month, and
year, are mounted on axial alignment, so as to bring their peripheries in substantially
the same plane at their points nearest or directly underneath the platen B. The
minute wheel is denoted by C, the hour and meridian wheels which move together
by D and D' respectively, the day wheel by E, the month wheel by F, and the
year wheel by G.
The several type wheels are mounted upon a spindle II carried by a framework A*.
The type wheel C, which indicates the minute, has a gear wheel I fixed to rotate
therewith, and intermeshing with a drive wheel I', carried by a shaft K, which, by
means of a crank arm k, has imparted to it a step-by-step movement at inter vals
of one minute by means of a drive wheel L, actuated by a motor (see Figs. 9
to 18 inclusive). It is intended that the shaft K shall complete a revolution once
every hour, and it is made to move the hour and meridian wheels one step at the
completion of each evolution, in the present instance by means of a mutilated
pinion, the teeth of which engage the teeth m on the end of the aim M, mounted
on a pivot m¹ carried by the framework. The aim M has fixed to rock therewith
an operating lever M', which carries at its free end a peculiar shaped pawl, which,
for convenience, I call a deerfoot. The aim M, and the lever M' fixed to rock
therewith, are both normally held in an advanced position by means of an actuating
spring m² attached at one end to a support on the framework, and at its opposite
end to an arm m³ projecting from the aim M on the opposite side of its pivotal
support.
The deer-foot carried by the aim M is in the nature of a tri-armed angle lever
pivoted at m' to the free end of the aim M. One aim N of the deer foot projects
upwardly into position to engage one of the twenty-four equidistant teeth or
abutments on the hour wheel D. Another arm N' of the deer-foot. which, in the
present instance, extends in a direction from the pivotal point opposite that on which
the arm N extends, provided with a stop pin n adapted to enter a slot m³ in the
arm M, and upon reaching the bottom of the slot, to prevent the deer-foot from
rocking furthei in one direction A third am N of the deer-foot extends in a
direction from the pivotal point of the lever intermediate of the directions of the
two arms N N', and is provided at its free end with a flat face n', for the purpose of
engaging a pun o projecting laterally from the free end of a locking level O. The
locking level O is pivoted on a suitable support of carried by the frame-work, and is
held normally in engagement with the hour wheel D by means of a spring o². The
operating face of the lever O is provided with a blunt tooth o (see Fig. 4), the
face o of which tooth is bevelled, so as to give the holding end of the tooth o³ a
pitch inwardly towards the axis of the wheel D, beyond the opposite end of the
tooth. The tooth o is intended to form an easy, but close fit between each two
successive abutments d, and its inward movement is limited by a shoulder o
adjacent to the end of the tooth o³, which shoulder o³ is intended to come in contact
with the outer end of the abutment d, against which the holding end of the
tooth o presses, when the lever O is in locking adjustinent.
The operation of the deer foot, the locking lever, and their actuating mechanism,
18 as follows.-
As the minute wheel approaches the end of the hour, the teeth on the mutilated
pinion engage the teeth m on the aim M, and gradually rock the arm M, and
hence the operating lever M', back against the tension of the sping m³. Such

page_text: movement of the lever M¹ brings the nose on the end of the aim N on the deer-root
against the preceding abutment d, and thereby rocks the deer-foot on its pivotal
support m', the piu n passing towails or out of the mouth of the slot m³. As the
arm M' approaches the limit of its backward movement, the arm N of the deerfoot
disengages the preceding abutment d, and the deer-foot is thrown into its normul
position (see Fig. 4) by means of a spung m³ (see Fig. 2) fixed to the arm M', and
resting with its fiee end on the pin n on the arm N' of the deer-foot. At the
moment the hour is completed, the mutilated gear on the pinion A disengages the
arm M, and permits the operating lever M to 1ock foward, under the tension of
the sping m. In moving forward, the end of the arm N of the deer-foot
strikes the pin o on the lever O before the end of the arm N of the deer-foot strikes
the abutment d on the wheel D, and before escaping from the pin o, swings the
lever O sufficiently to withdraw the tooth o³ fiom between the two abutments d.
thereby leaving the wheel D fice to be rotated. At the very moment the tooth o³
releases the wheel D, the aun N of the deer-foot engages the abutment d, and
forces the wheel D around. At this same moment, the end n' of the arm N of the
dec-foot escapes from the pin o, and the level O presses back again towards the
abutments d on the wheel D. As the bevelled face of of the tooth o rules along on
the outer end or face of the abutinent d, the forward or holding end of the tooth
will gradually creep inward towards the axis of the wheel, so that when the next
successive abutment d comes to a point in radial alignment with the holding end of
the tooth o³, the holding end of saul tooth will overlap the said abutment to an
extent sufficient to ensure a positive stop of the wheel D at that point
The meridian wheel D is fixed to rotate with the wheel D, so that the
symbols A M. and PM. will fall opposite the respective hours from one to twelve
counting from midnight until noon, and from one to twelve counting from noon to
midnight, respectively. As the twenty-four hours pass, a day wheel E is moved a
Single step by means of an operating lever and deci-foot, quite similar to the
operating lever M' and the deerfoot carried thereby, and is arrested by a locking
lever quite similar to the lever O controlled by the deer-foot, as already explained.
The operating lever coiresponding to M is however, in this instance, thrown back
against the tension of its actuating spung by means of an arm P provided with an
extended bearing face P
at its fiee end, which face is engaged by a roller d' on the
hour or meridian wheel, in the present instance carried by the hom wheel D, and
60 located with respect to the atm P, that as the wheels D D' approach the end of
the twenty-four bois, the lever P will be rocked back against the tension of its
actuating spring, to bring the deci-foot into position to release the locking lever O,
and also to force the day wheel one step forward, and at the moment the twenty-
four hours are completed, the roller d' will escape from the face of the arm P,
permitting it, and hence the operating lever, to advance under the tension of the
actuating spring, and force the day wheel forward one step. The operating
level for advancing the day wheel is denoted by M and its locking lever by O. The
number of equidistant abutments on the day wheel E will be thuty-one, and they
are denoted by e.
As the day wheel completes its thi'ty-one steps, it serves to move the month
wheel F one step, in a manner quite similat to that in which the hour and meudian
wheels operate the day wheel. The operating level for this purpose is denoted
by M, the locking lever by 02, the operating aim by P¹, its extended face by p',
and the roller on the day wheel by e¹.
The abutments on the month wheel are denoted by f, and there are twenty-four
of them at equal distances apart, a sufficient number to correspond to the succession
of twelve months for two consecutive years.
The year wheel G' is intended to be set by hand at the beginning of each
successive year, and it is held in position by means of a notched disc 'g, provided
in the present instance with twelve equidistant notches g' in its 'peliphety, and fixed'
to rotate with the year wheel, a spring actuated cam g³ being provided with a
V-shaped nose g³ adapted to enter one of the notches . To set the year wheels
13

page_text: the aim is liited to release the disc g, and the disc is then rotated a distance
between two notches, and the arm g ngain permitted to fall into engagement
with it
The operation of the stamp might go on as thus described without erro,
provided that each of the months contained thu ty-one days. As thus is not true, it
is necessary that there should be provided some means for correcting the error, by
advancing the day wheel one or more steps at the end of such months as have less
than thirty-one days, in order to complete the thirty-one, and register the new
month at the proper time I have provided for this by a crank arm Q, secured to
rock with the operating lever M, and provided with a laterally projecting operating
piu gat its free end. In position to engage the pin q, I locate a rotary snail
cam q', fixed to a spindle q, which projects through the casing, and is provided
with some suitable means foi turning. By rotating the snail cam q' one revolution,
the aim is lifted, thereby throwing back the operating lever M³, and is then
released, permitting the operating lever M to advance and set the day wheel
forward one step
A second evolution of the snail cam will set the day wheel
forward a second step, and so on.
In connection with the printing mechanism as heicinabove described, I provide
an inking device consisting of an inking ibbon engaged with a pair of spools R
and R', one at each end of the ribbon, the said spools being mounted in casings
which have a removable engagement with the interior of the casing A. In the
present instance, I have shown the casings as consisting of back plates S S',
each provided at one end with an oblique slots for receiving the shank of a headed
stud oi sciew set in the side of the casing A, the opposite end of the back plate
being provided with a projecting hook s', which is adapted to enter a socket in the
corner of the casing. From the back plate, ends ss project at 1ight angles to
the back plate, and these seive as supporters for the spool spindler, leaving the
front open for the passage of the ribbon, which passes from the spool over a guide
rolle mounted in the ends so so at their upper front portious
By elevating or removing the cover a of the casing A, the ribbon casings
may, one or both of them, be removed at pleasure, and another set similai-thereto
be inserted in their places, while the ubbou on those removed is being changed or
1e-inked The spoole R and R' are arranged to iotate in either duection at
pleasure, sufficient tension being applied thereto to hold the abbon smooth by
meatis of springs s², which surround the spool spindle r, and are confined between
pins on the spindle and the end of the casing, and which tend to diaw a shoulder
or disc on the spindle against the end of the spool. The spool spindles are
provided with thumb attachments s', which project outside the casing, for the
purpose of moving the ribbon along at suitable intervals, as the stamp is
used.
The casing in which the parts of the motor are mounted consists of a fiont,
plate A3 and rear plate A, and tie pins or guders A³, for securing the front and
rear plates together at a suitable distance apart.
The spring for actuating the motor train is housed within a drum T suitably
mounted between the front and rear plates, and provided with a driving gear wheel T¹
fixed to rotate therewith.
The actuating spring for the time train is housed within a rotary dium T,
suitably mounted between the front and rear plates, and provided with a during
gear wheel T³, fixed to rotate therewith.
Intermediate of the gear wheels T' and Ts, I mount a spindle T', extending
through from in front of the front plate to the rear of the rear plate, and provided,
on its rear end, with a squared portion t, for the purpose of attaching thereto a key
for turning it. Adjacent to the squared portion t, the spindle is provided with a
colla on shoulder, for the purpose of exerting a pressure upon the spindle, to
slide it longitudinally towards the front To the front end of the spindle T', there
is secured the power transmitting wheel L, provided with an annular series of
teeth on the edge of the periphery, and with a crank pin projecting from its

page_text: front face. The spindle T is loosely mounted in both rotary and longitudinal
adjustment within a sleeve T, which, in tuin, is loosely mounted in suitable
bearings in the front and rear plates A³ A', and which sleeve has fixed to its front,
intermediate of the wheel L and the front plate A³, an arm to, the fice end of which
18 held normally in engagement with the teeth on the wheel L, by the pressure of
a spring interposed between the collar or shoulder on the spindle and the rear
end of the sleeve T. Fixed to rotate with the sleeve T³, is a pinion T6, provided
with a toothed wheel ', fixed to rotate with the pinion There is also loosely
mounted on the sleeve T³, a pinion T', having fixed to rotate therewith a toothed
wheel t8.
The drive wheel T" of the motor gear engages the pinion Te fixed to rotate
with the sleeve T, and tends to rotate it; and hence the arm t, and, when
the latter is in its normal engagement with the power transmitting wheel L,
to advance the wheel L The movement of the pinion T, under the pressure
of the drive wheel T¹, is permitted when the stop wheel is released by the
trip mechanism. Motion is transmitted to the stop wheel U from the pinion Te
by means of a pinion u fixed to rotate with the wheel U, in engagement with a
toothed wheel U, having a pinion fixed to rotate therewith, the pinion ¹ being
engaged with the toothed wheel 7 fixed to rotate with the pinion Tº.
The dive wheel Ta of the time train transmits power through the pinion T7 to
the toothed wheel 8, thence to a pinion u³, fixed to rotate with the toothed wheel U³,
thence to a pinion u³, fixed to rotate with a toothed wheel U³, and theuce to the
escapement wheel U
Fixed to rotate with the toothed wheel U, is a lantern pinion a', the bars of
which serve to actuate the trip lever for cleasing the stop wheel U herembefore
referred to
The trip leve is denoted, as a whole, by V, and is secured to a rocking shaft v
suitably mounted in front and rear frames. One arm of the love has its and
extended into engagement with bars of the lautern pinion ut, while the other arm
of the level extends into engagement with the stop wheel U The stop wheel is
provided with a pin a, projecting from its side, and the arm 2 of the trip level is
provided with two abutments, located at the side of its free end, and lapping
past cach other at their free edges, and spaced apart sufficiently to permit the
pin to pass between them The shaft e, to which the trip lever is secured, has
fixed thereto an aim, to the free end of which one end of the spring is secured,
the opposite end of said spring being secuted to a stable supput on the front
plate. The tension of the spring is such as to tend to rotate the shaft in a
direction to hold the free end of the aim of the tip lever as far as possible
towards the centre of the stop wheel U. At the same time, the free end of the
arm v of the trip lever is 80 located with respect to the bars on the lantern
pinion u, that before the bar has passed the free end of the aim a', it will have
rocked the tip lever sufficiently to permut the pin u on the stop wheel, to escape
under the abutment on the arm 2, and in contact with the abutment v². In this
position, the stop wheel U will be held until the bar on the lantern pinion has
passed the free end of the arm v', when the tension of the spring will rock the
tip lever in a duection to permit the pan u to escape over the abutment ³, and
the stop wheel U be thereby permitted to make nearly a complete revolution, its
arrest being caused by the engagement of the pin u with the abutment v³, which at
this moment is drawn down into its path by the rocking of the trip lever under the
tension of the spring v.
The bars on the lantern pinion may be located at such intervals apart as to
operate the tip lever every minute, half minute, quarter minute, or at any other
desired interval of time, and it will therefore follow that the rotation of the stop
wheel U will take place at such predetermined intervals of time, and hence,
in the manner herein before described, the power transmitting wheel L will, at
such intervals of time, act through its crank pin upon the type wheels and time
indicating hands under its control.

page_text: The shaft for transmitting notion from the wheel L is denoted by K, and the
armon said shaft is provided with a slot for the reception of the crank pto on
the wheel I, the relation of the wheel L to the arm being such, that the wheel L
may be thrown out of engagement with the arm to, without disturbing the
engagement of the pin t with the slot in the aim k.
By mounting the spindle T', to which the power transmitting wheel L is secured,
so as to permit it to be moved longitudinally against the tension of the spung t°,
out of engagement with the arm, I provule for rotating said power transmitting
wheel at pleasure, so long as it is out of engagement with the arm 5, and thereby
operating the type wheels and time indicating hands of the stamp or whatever other
mechanism may be duiven by said power-trausmitting wheel L, to set it into the
desired position, without in any manner disturbing either the time or motor trains
o gear, and at the same time utilizing the said spindle T for purposes of mounting
the power transmitting wheel while in normal engagement with the motor and
mechanism. The rotary movement of the stop wheel U is prompt and rapid, so
that the power transmitting wheel L, and hence any mechanism that may be
operated thereby, will remain at test, with the exception of brict moments, at such
intervals as may be determined upon, since, no matter how rapid the stop wheel
rotates, it will find the abutments down in position to arrest it, for the reason that
the abutment has been drawn down into the path of the pin simultaneously
with the passage of the pin over the abutment vª
The attachment for advancing the time card, so that the workman's time of
anval and departme may be recorded, is constructed and arranged as follows
-
The fixed or immovable portion of the attachment is denoted by W, and it is
removably secured to the top of the casing, preferably by means of suitable
sciens w, which pass through lugs w¹ upon said fixed part, and enter the top of the
casing. A plate W is for ined integral with, or secured to the fixed piece W, at or
near one end thereof, in position to form an extension of the top of the casing,
when the piece W is secured thereon
The fixed piece W is further provided with upper and lower longitudinal
grooves w³, and an elongated slot w is cut thungh the wall between the upper
and lower grooves, for the purpose which will be hereinafter described.
The time caid holder is denoted by Y, and it is mounted to slide upon the fixed
piece W in the following manuer -A tongue y extends along the bottom of the
holder Y, and cuters the longitudinal groove or recess on the fixed piece W.
This tongue fits with the groove w², so as to allow the holder Y to have a free
sliding movement along the fixed piece W. A flat spring y is fitted within the
groove 3 of the fixed piece W, and is secured to the card holder Y by means of a
suitable screw y, which passes through the slot w, ind enters the tongue y.
By this means, the card holder Y 18 allowed a limited sliding movement along the
hxed piece W.
The holder Y is provided with a suitable handle y³ at one end, which adapted
10 be gasped by the attendant, for sliding the holder along the fixed piece W.
For forming a support for the time card, I extend the bottom of the holder Y
laterally at its opposite ends, as chewn at y', y, and connect the onter ends of the
said laterally extended portions by means of a suitable connecting bar y.
These
laterally extended ends y', y, are provided with suitable stops or abutments y, y,
between which the card is inserted into position to be stamped.
For yieldingly holding the card in position upon the bolder Y, I provide suitable
springs, yo, which are secured at their immer ends to the main portion of the
holder Y, and their outer ends rest upon the laterally extended portions y', y of the
holder The main portion of the holder Y, the laterally extended puitions y' y³,
and the connecting portion y, form an upen frame-work, which will receive the
time card, and hold it against displacement in any direction, so as to allow the time
of arrival or departure to be printed at the proper place upon the card. The outer
edge of the connecting bar y is tuned downwardly, as shewn at y", so as to
overlap the front of the top of the casing. This downwardly extended hip y

page_text: This will
18 reinforced by a suitable wire or rod y¹³, as, shewn in Fig. 18.
prevent the edge of the card from catching, as it is inserted into the holder Y.
Foi advancing the holder Y regular distances along the fixed piece W, for
permitting the times of arrival and departure of the workman to be indicated, and
for locking it in each of its adjustments. I provide the following mechanism:
A series of holes or recesses y are formed along the top of the sliding holder Y,
and are spaced at equal distances apart. There are pielerably twenty-four of said
holes or recesses, so that the sliding holder W may be advanced the distance of
four holes or recesses each working day for a week. A vertically-movable spring-
actuated lever Z is mounted in a suitable laterally-swinging bearing piece z, which
bearing piece 16 pivoted to a laterally extended lug a¹ of the fixed piece W, by
means of a suitable screw 22. The front arm of the lever Z is provided with a
downwardly extended pin 23, adapted to enter the several openings or recesses y18
on the holder Y, when the said fiont arm is in its normally lowered position. This
pin is held against displacement within the said openings or recesses by means of
a coiled spring, which engages the rear arm oi thumb piece at its upper end,
and the laterally swinging bearings piece z at its lower end. It will thus be seen,
that as the thumb piece of the lever Z is depressed, the pin 23 will be released
from engagement with the recesses in the sliding holder Y, and the said holder
Bill be fiee to slide along the fixed piece W.
The lever Zis yieldingly held in a position at right angles to the sliding
holder Y, by means of a coiled spring, which preferably surrounds the pivot
screw z², one end of the said spring engaging the laterally swinging bearing
piece 2, and its other and engaging the laterally extended lug 2 of the fixed
piece W. It will thus be secu, that the sliding holder Y may be slid along the
fixed piece W a short distance without releasing the lever Z from its engagement
with said holder Y, the said lever being free to swing laterally in its hearing z.
The distance of its said limited movement of the holder Y is preferably the
distance between two of the recesses 313, and is positively regulated by means of
two stops 7, 8.
"
In operation, supposing that the times of arrival and departure have been
printed upon the card down to Friday, the lever Z is caused to engage the proper
opening or recess y, so as to bring the space on the card opposition the first word
"in," in the "day" division over the type wheels of the time stamp, the time
caid is then inserted into its position in the holder, with its face down, and the
plunger is then depressed, causing the type wheels to print the requued time in
said space opposite the first word " in, As the workman goes out at noon, the
lever Z has been raised, and the holder Y been advanced one notch, so that the
space to be printed opposite the first word "out" in the "Friday" space, is in
position to have the time stamped therein. This process is repeated as often as
the workman arrives and departs from work. As the different workmen are going
and coming at about the same time during the noon hour, the feature of my device
of being able to slide the holder Y along the fixed piece W the distance betweco
two recesses, the attendant can leave the holder as it is, to stamp the time of a
workman going out, and can slide the holder forward to stamp the time of a
workman coming in, without operating the level Z.
