page_text: I PHILIP ARTHUR NEWTON of the Office for Patents, 6 Breams Buildings, Chancery
Lane in the County of Middlesex, Patent Agent, 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 :-
In this improvement is employed time mechanism which may consist of an ordinary
clock, and from this clock, by means of intermediate mechanism, are operated a
number of indicators in accordance with the movement of the clock, the positions of
the indicators changing regularly in accordance with the well known divisions of
time. In conjunction with the indicators employed a stamp which, when forced
downwardly upon an inking ribbon passing over the indicators, will record upon
an interposed paper or document, the date and time of day when the impression was
made.
In the accompanying drawings,
Fig. 1 is a vertical section taken on the plane of the linea, Fig. 2.
Fig. 2 is a vertical section taken at right angles to Fig. 1, and on the line y, y,

page_text: Similar letters of reference designate corresponding parts in all the Figures.
The improvements involve the use of clock mechanism, which may be of any
desirable kind; which clock mechanism transmits motion to a series of indicating
wheels whereby time may be recorded upon a paper or document, when the same is
forced against the indicator wheels. The time indicated will be that of the year, the
month, the day, the hour, the minute, and whether the impression is made during A.M.
or P.M., the shortest duration of time indicated being that of minutes. Motion to
operate the minute indicating wheel is transmitted directly from the minute shaft.
Referring more particularly to Figs. 2, 3 and 4, A designates a pinion driven from
the pinion A¹ on the minute shaft of the clock. These pinions are of the same diameter,.
and have the same number of teeth, consequently the pinion A will rotate at the same
speed as the minute shaft of the clock. The pinion A is mounted upon a shaft, a,
journalled in suitable bearings in the main frame, B, of the time indicating.
mechanism for the stamp. Upon the shaft a, is mounted a ratchet wheel A²,"
which ratchet wheel has sixty teeth.-Rigidly mounted upon a rock shaft A³,
which latter is also journalled in the main frame B, is a lever A.-The lever A
bears near its lower extremity a tooth a¹, shown more clearly in Fig. 9.-The
tooth a¹ is in contact with the teeth upon the ratchet wheel A.-The ratchet
wheel A rotates in the direction of the arrow shown thereon in Fig. 9; con-
sequently, as it rotates, the tooth a¹ will be moved outwardly by the teeth upon
the ratchet wheel successively, causing the lever A to rock, and causing the
rocking of the rock shaft A³-Upon the outer end of the rock shaft A³ is a
finger a², rigidly secured thereon. Against this finger bears a spring a³, which
spring is secured near its lower end in a suitable support made, fast to the
frame B. The tendency of this spring is to always cause the rocking of the rock
shaft A3, in such manner that the tooth a¹ of the lever A will be maintained
firmly in contact with the teeth of the ratchet wheel A2-When, therefore, the
lever A has been rocked by the rotation of the wheel A2, and the tooth a¹ moves
past one of the teeth on the ratchet wheel, it will be quickly sprung into the
adjacent space between the tooth just passed and the next tooth. The upper arm
of the lever A bears, near its extremity, a pawl a-This pawl is loosely hung
upon the lever. Its outer extremity bears a tooth a, which tooth engages with
the teeth upon a ratchet wheel A. This ratchet wheel is rigidly secured upon
one side of a minute indicator wheel Aº. The minute indicator wheel bears, upon
its periphery, raised Figures extending successively about the periphery, and
indicating the minutes from one to sixty. A complete rotation of the minute
indicator wheel occurs each hour. When the ratchet wheel A² rotates to cause
the rocking of the lever A, the pawl a will be moved along a distance equivalent
to the length of a tooth upon the ratchet wheel A5, and when the tooth a¹ on the
lever A springs into the next notch on the wheel A2, through the action of the
spring a³, the pawl a will be moved rearwardly, so that the tooth a thereon will cause
the rotation of the ratchet wheel A', a distance equivalent to the length of one of the
teeth thereon. As there are sixty teeth on the wheel A, and there are sixty impulses
given to the lever A by the wheel A2, there will be sixty impulses given to the
wheel A³, and to the minute indicator wheel A.-A7 indicates a stop pawl mounted
upon a rock shaft a journalled in the frame B. Outside the frame, said rock shaft
has rigidly secured to it a finger as, actuated by a spring a' in a manner similar to the
spring a³. This spring operates to keep a toe a¹ upon the stop pawl A' in constant
contact with the teeth of the ratchet wheel A³.-The stop pawl prevents the reverse
rotation of the wheel A from the direction in which it was rotated by the pawl a³.
Upon the shaft a is rigidly mounted a cam b.-As shown, this cam is what is
known as a snail cam. Against the periphery of this cam bears a tooth b¹ upon one
arm of the lever B³, shown more clearly in Fig. 8.-The lever B¹ is rigidly mounted
upon a rock shaft b journalled in the frame B. Its upper arm has pivotally connected
with it, a pawl, 63, provided with a tooth . The tooth 6 engages teeth upon a ratchet
wheel B, rigidly secured to one side of an hour indicator wheel B³.-The hour

page_text: indicator wheel B³ has upon its periphery raised figures indicating twelve hours.-As
the shaft a rotates but once each hour, the snail cam b will consequently be rotated
but once in the same period.-As the tooth of the lever B bears against the
periphery of the cam b, the leyer will be gradually rocked during the rotation of the
cam, until it has moved the pawl b, and the tooth & thereon, a distance equivalent to
the length of one of the teeth on the ratchet wheel B. At each complete rotation of
the cam b, the tooth b¹ on the lever B¹ will move over the step upon the cam by reason
of the action of the spring 65 operating upon a finger 6 mounted on a rock shaft 62,
and acting in the manner previously described for the springs a³ a.--When so rocked,
the pawl 63 will be retracted, causing the tooth 64 to rotate the ratchet wheel B² a
distance equivalent to the length of one of the teeth thereon, thus rotating the hour
wheel a distance equivalent to the distance between two of the raised figures upon its
periphery. As the cam b rotates but once each hour, an impulse will be given to the
hour indicator wheel but once each hour.
Co-operating with the ratchet wheel B' is a stop pawl B4, actuated by a spring b?,
operating upon an arm 6³ rigidly secured upon a rock shaft 7 in the manner previously
described.
There will now be described the manner in which the days of the month are
indicated, and also the divisions of each day into A.M. and P.M. Upon the minute
shaft S of the clock, outside the pinion A², is a pinion C. The pinion U gears with a
pinion C¹ mounted upon a stud e extending from the frame of the clock. Upon the
stud C₁
outside of the pinion C, is a pinion 03, which pinion gears with a pinion C³,
which pinion is rigidly mounted upon a shaft C4 journalled in the frame B. Upon
the shaft C are rigidly secured two cams C5 C6, which rotate with the same.-The
pinions C, C1, C2 and C³ are of such diameter that they cause the rotation of the
shaft C once in every twenty-four hours.-The cam 5 is a snail cam. Against
its periphery bears a tooth e' upon the lower arm of a lever C7 mounted upon a rock
shaft C journalled in suitable bearings in the frame.B. This lever is spring actuated
in one direction by a spring c, acting upon an arm c³ rigidly secured upon a rock
shaft C, outside the frame B, in the manner previously described. The upper arm
of the lever C has pivotally connected to it a pawl C, which pawl is provided with
a tooth c, which pawl engages the teeth upon a ratchet wheel C10; which ratchet
wheel is rigidly secured to one side of a day indicator wheel C, the periphery of
which has formed upon it raised figures indicating the days of the month. The
ratchet wheel C is provided with thirty-one. teeth. Each time the snail cam rotates,
it causes ths gradual rocking of the lever C7, and causes the movement of the tooth c
upon the pawl C, a distance equivalent to the length of one of the teeth upon the
ratchet wheel C10; and each time the tooth c¹ on the lever c' moves off from the
step upon the cam, the pawl c³ is retracted by the spring c², causing the rotation of
the ratchet wheel c¹0 a distance equivalent to the length of one of the teeth on said
wheel. As there are thirty-one such teeth, thirty-one impulses will be given to said
wheel, and to the day indicator wheel, each month. If there are less days in the
month than thirty-one, the lever c' may be rocked independently of the cam es, to
set the day indicator wheel. This is accomplished by a pin p secured to the lever c',
and extending through a curved slot p¹ to the outside of the case K.
It is desirable to indicate the division of the day into A.M. and P.M.; for this
purpose is arranged upon the shaft C, an "S" cam, bearing against the periphery
of which is a tooth d upon a lever D, mounted upon a rock shaft D' journalled in
the frame B. The lever D is spring actuated by a spring d' operating upon a
finger upon the shaft D' outside the frame B, and adapted to hold the lever D in
contact with the cam C, in the manner previously described. The upper arm of the
lever D bears a pawl D³, provided with a tooth d³, engaging the teeth upon a
ratchet wheel D³, rigidly secured to one side of an A.M. and P.M. indicator wheel D.-
The indicator wheel D³ is provided upon its periphery with letters A.M. and P.M.
There are shewn twelve such combinations of letters, and twelve teeth
the
upon
ratchet wheel Da, but any desired number may, be used. Each time the "S" cam is.
rotated, it twice rocks the lever D at regular intervals (or, in other words, once every

page_text: twelve hours), in such manner that the pawl D² will be moved inwardly upon the
ratchet wheel D³, a distance equivalent to the length of one of said teeth, and each
time the tooth is moved off from a step upon the cam C, the lever will be retracted
by the spring d¹, to cause the rotation of the wheel D³, a distance equivalent to the
length of one of its teeth, thus giving an impulse to the wheel D* once every twelve
hours.
Co-operating with the ratchet wheels ("%, D³, are stop pawls D³, De, mounted upon
shafts 17, 18, and actuated by springs D, D₁, bearing against fingers D",
rigidly mounted on the shafts D', D. Co-acting with each of these levers A+. B¹, C7,
and D, are springs e. These springs are shewn as flat, and secured near one of their
ends to the said levers respectively. At their free ends, they bear against squared
ends of the pawls a, 63, 0°; and D2, and serve to maintain such portions in engage-
ment with the teeth upon the ratchet wheels A³, B2, C110 and D³ respectively.
Co-operating with the pawls as 3C and D, are stops, which stops consist of pins
extending inwardly from the side portions of the frame B, and into the path of toes
upon the pawls. These stops prevent the pawls from being moved too far in one
direction by the respective springs a¹, b, c², and d².
In Figure 6, is shewn an indicator wheel G for indicating the months of the year,
upon the periphery of which wheel are raised letters indicating the twelve months.
Upon the wheel G is rigidly secured a toothed wheel G¹; also secured upon the
frame B, is a support g, for a spring gl.-The spring g¹ bears upon a stop pawl g³,
which stop pawl is adapted to engage the teeth of the toothed wheel G₁-Extending
to the outside of the frame B is a shaft g3. Upon the inner end of said shaft is
rigidly secured a toe g. The toe g¹ is in contact with the teeth upon the toothed
wheel G. When the shaft g³ is rotated, the toe .g will cause the rotation of the
toothed wheel G₁, a distance equivalent to the distance between two teeth on
said wheel, and consequently the rotation of the wheel G a distance equivalent to the
distance between any two adjacent months indicated upon the wheel G.
A coil spring g abuts at one end against the wheel G, and at the other against.
a collar, whereby the toe g is always maintained in engagement with, the
wheel G¹.
In Figure 11, there is shewn an indicator wheel for years. Upon this wheel, any
number of years may be indicated in raised letters. This wheel may be rotated by 1
hand, by placing the finger upon the raised figures indicating years upon the periphery
of the wheel, and moving it circumferentially. In combination with this wheel, which
is designated by the letter H, is shewn a toothed wheel H¹, and a stop pawl h¹
actuating a spring h³.
All the wheels A, B, C, D, G, and H, are mounted upon a single shaft, which
shaft passes loosely through them, so that they may be rotated freely thereon.-The
shaft is rigidly secured near its ends in the side portions of the frame B.
-
In Figure 3 is shewn more clearly a means for indicating the sort of record, the
time of filing of which it is desired to record. This record consists of an octagonal or
many sided barrel J, mounted upon a shaft j, journalled in the side portions of the
frame B. Upon the outer end of this indicator barrel is secured a hand piece j², by
which the shaft and the barrel J may he rotated. It is preferred that the said hand
wheel be as many sided as the barrel, and that upon each side of the hand piece should
be delineated a record agreeing with that upon the corresponding side of the barrel
when both are uppermost, or in a position to be printed upon. Upon the upper side
of the printing mechanism, and opposite the indicator last described, may be arranged
the name of a person, firm, or office, as the case may be, for whom the record is being
made. This indicator is designated by the letter J2, and the same may be stationary,
and cast in a top plate J³ for the indicator.-Upon each side of the top plate J³ are
arranged rollers j³, over which may be passed an ink ribbon."
The case K contains; in this example of the improvements, both the clock mechanism
and the time indicator mechanism. Upon the top of the case K, and rigidly secured
thereto, is an arm k, which bears, near one end, an upright tubular portion, through
which extends a tube ¹, upon the upper end of which is a hand piece 2. Within the

page_text: tubular portion k', is arranged a coil spring ³. Upon the lower end of the tubular
portion is arranged an impression plate . The spring 3 abuts, at one end, against
the hand piece 2, and at the other end against a screw, passing through the tubular
portion of the arm k and the tube ¹. By depressing the hand piece ², the impression
plate may be pressed downwardly upon the top of the figures or letters, appearing
upon the indicator wheels, and the coil spring ³, and, above the inking ribbon, which
may be employed.
and
If now, a paper or other document be placed between the impression plate
the indicators appearing at the top of the indicating mechanism, and the hand piece k³
be depressed, the time at which the impression was made will be accurately imprinted
upon said paper or document. As the indicator wheels for the minutes, hours,
days, &c., are all of the same diameter, the time which it is desired to indicate will be
accurately presented at the same time, just above the surface of the plate J³, in order
to accomplish the impress referred to.
In order to accomplish the setting of the clock and the time indicator mechanism at
one and the same time, a shaft L protrudes, near one end, beyond the case K, which
shaft is journalled in the side portions of the frame B. Upon the inner end of this
shaft is rigidly mounted a pinion 1, which pinion is adapted to engage the pinion A¹
upon the minute hand shaft of the clock.-This pinion is not, however, always in
engagement with the pinion A¹. It is desired to keep it normally out of such
engagement, and for this purpose, is employed a coil spring, abutting at one end
against one of the side portions of the frame B, and at the other against a collar 1
rigidly secured to the shaft L. The tendency of this spring is to force the pinion
out of engagement with the pinion L'. By forcing the shaft L inwardly, however,
against the resistance of the spring 1, the pinion will be caused to engage the
pinion A', when, by rotating the shaft L, the pinion A¹ may be rotated in such
manner as to set the clock properly. As the pinion A¹ controls the time indicator
mechanism, by rotating the said pinion, the time mechanism, or in other words, the
indicator wheels operated by the clock, are set at the same time as the clock.
