page_text: I, HANS REICH, of Obsplatz 6, Bozen, Tyrol, Austria, Clock Maker, do hereby
declare the nature of this invention to be as follows:-
This invention relates to a clock which is connected with electric signal bells, and
causes at any desired predetermined time, the sounding of an electric alarm signal;
and, if the latter is not stopped in due time, the said clock, after a desired predeter-
mined interval of time, puts into operation a second signal which is situated at a
distance from the clock.
The clock has for object to remind a person in a certain place (for example, a boiler
attendant, a boiling master etc.,) by means of a bell signal which sounds at a determined
time, that some particular operation is to be performed. It is the duty of the said
person to stop the said signal at once, because if the said signal is not stopped,
either through neglect of duty, illness or accident to the said person, a second aların
bell which serves as a check, and may be, for example, arranged in the manager's or
foreman's office, will sound, and thus give notice in good time that the first signal
has not been obeyed, or could not be obeyed, and that therefore measures must be
taken in the case of the occurrence of an accident to bring aid in order to prevent
interruption of the working, or to obviate in time the beginning of damage.
In order that the said signal shall be given, there is arranged in the clock a
contact piece which is moved together and simultaneously with the hour hand, and
which is adapted to be set by means of a special hand. This contact piece constitutes
the end of an electric conductor which closes a circuit leading to an alarm bell by
the raising of a contact lever; which lever, if the contact is not at once broken by
means of a switch, closes by the contact of a second contact-lever a circuit leading
to a second alarm bell, the arrangement being such that the interval of time between
the making of the two contacts can be predetermined as desired within certain
limits by means of an adjusting lever acting upon the second contact-lever.
The accompanying drawings illustrate a control clock constructed according
to this invention. Fig. 1 is a front elevation of the clock, with front portions
removed showing the connections of the respective electric signal-bells, and the dial
and pointers by dotted lines. Figs. 2 and 3 are respectively vertical and part
horizontal sections of the clock. Fig. 4 is a rear side view of the contact wheel with
the adjustable contact, and Fig. 5 is a side elevation of the latter, together with the
setting hand or pointer. Figs. 6 and 7 are elevations of the contact mechanism
before and after the setting of the hand contact.
As shown in Figs. 1 and 2, there is placed upon the hour tube a of any suitable
clock, a wheel A₁ with its sleeve a', which is clipped by means of a spring a²
engaging in a groove in the hour tube, in such a manner that it can be rotated freely
on the hour tube by means of the control hand A* connected with the sleeve a³,

page_text: whilst the said wheel A¹ is held so firmly that it is moved along by and with the
hour hand a³.
In the rim of the wheel A¹, there is let in, so as to be capable of rotation, a ring a³
(Fig. 4) which is held by means of the plates a', and which is provided with a pro-
jecting contact a' that is formed in the centre with a slot a®.
For the purpose of holding the contact piece fast during the adjusting movement
there is employed a lever H which is pivoted at h on the front plate of the clockwork,
and the arc-shaped arm h¹ of which enters its hooked end into the notch a of the
contact piece a as soon as the lever H is engaged and raised (see Fig. 6) by the pin h³
(Fig. 3) projecting from the clock casing, whereupon the control hand can be shifted
as hereinafter described without moving the contact piece.
The current is supplied to the contact a from a battery B through the lead b
connected to the clockwork A and through the rubbing spring 61 bearing on the
wheel A¹ (Fig. 1).
On the front plate of the clock work A there is (pivoted on the bolt c¹ on a
vulcanite plate c) a contact lever C which, in the position of rest (Fig. 1), is kept
bearing against the stop-pin c³ by means of the lead c² which is in part formed as a
coiled spring.
The lead c² of the contact lever C leads to the alarm mechanism D (Fig. 1) which
is situated in the same room as the clock, and whose return lead 62 is connected to
the battery B. In the normal position of the contact lever C and of the contact a³,
the circuit of the alarm mechanism D is interrupted. But it is closed and thereby
caused to sound the alarm when the contact a' has been moved forward by the hour
hand to such an extent as to come in contact with the nose c of the contact lever C.
Above the contact lever C there is pivoted, in the same manner as this lever, on the
vulcanite plate c, a second contact lever E, which is pressed down against the stop
pin e by means of a lead e that is in part formed as a spring. In the position of
rest of the two contact levers C and E, the connection of the lead e is also inter-
rupted. This lead e leads to the signal bell D¹ that serves as a distance signal and
is situated in a room at a distance from the elock, and whose return lead ² is also
connected with the battery B.
When the contact lever C is raised by the contact a running up on its inclined
nose c¹, then as soon as the lever C touches the nose of the contact lever E, the
circuit be is closed, and the signal bell D¹ is set going. The amount of the distance
of the contact lever nose e from the contact lever C determines the interval of time
which elapses between the sounding of the first signal bell and the sounding of the
second signal bell.
For the purpose of enabling this interval to be predetermined, as desired, say, for
example, from 1 to fifteen minutes, the lever H is provided near its pivot h with an
arm h³ which carries an insulated pin h* upon which the contact lever E bears. The
free end of the lever H bears with its pin h2 upon an eccentric or cam h³ mounted so
as to be capable of rotation on the clock casing. According as the pin h² bears on
the lowest point or on the highest point (marked "O") of the eccentric h³, the
lever H is depressed or is raised (see Figs. 6 & 7), whereby the contact lever E is
moved in such a manner that, in the first case, the distance between the two contact
levers C and E, and consequently also the interval of time, is increased, whilst in the
other case, the contrary happens.
The operation of setting the contact a to give a signal at a predetermined time
by the clock D is as follows:-In the normal position of the clock (Fig. 1) in which
the control hand A2 stands at "o," the contact piece a7 is situated only at such a
distance from the nose ct of the contact lever C as is just necessary to prevent the
circuit being closed.
Let us assume that the control clock is to be set so that the signal of the bell D
shall sound exactly two hours afterwards with reference to the position of the hour
hand at the time being:-
For this purpose, the control hand A2 is advanced slowly in the direction of the

page_text: hour hand, until the signal is given by the bell D, whereupon by raising the lever H
its forward end h¹ is hooked into the notch a of the contact piece a7, whereby the
latter is held fast (see Fig. 6).
Now, by then setting the control hand A' upon the Figure II. of the clock face,
the contact wheel A' is rotated as well, whilst the contact piece a7 (which is held
fast) in the wheel A¹ remains behind by the amount of the angular rotation of the
hand A. The lever H is then released and pressed down by the spring ho (Fig. 1),
and the contact piece a7 is therefore released. Now, the control hand A2 is set back
to "o" whereby the contact piece a' moves away to a corresponding extent from the
nose of the contact lever C (see Fig. 7). Unauthorized adjustment of the control
hand is prevented by closing in the hand mechanism of the clock by means of a
glazed cover F which can be fastened with a lock G (Fig. 2), which cover also covers
in the eccentric /³.
If during the operation of the clock, the contact wheel A¹ together with the control
hand A2 is moved forward by the hour hand as through the amount of two hours, the
signal bell D will be caused to sound in the manner above described.
For the purpose of enabling the first signal (or it may be both signals) to be at
once stopped by means of the checking part, there is provided on the clock a
vertically movable switch- I (Figs. 1 and 2) which is pressed down by means of a
in teeth of the contact
spring i, and which engages with its operating pawl
wheel A¹, and by moving upwards, causes the control hand A2 to be moved back.
The rotation of the control hand backwards by means of the switch I beyond the "o"
point is prevented by means of a space 2 which is formed in the toothed periphery
of the contact wheel, and into which, when the switch rod is pulled down, the pawl
enters and thus comes out of gear with the teeth. So long as the control hand A²
is set to a determined hour, the signal, (when the said hand has been returned to
its "o" point after the signal has been given) will again sound on the expiration
of the predetermined interval of time.
The duration of the sound of the signal is determined by the width of the contact
piece a7.
If the sounding alarm mechanism D is not at once thrown out of operation, the
second alarm D₁ will sound after the interval of time which has determined by the
adjusting mechanism h5, H, h. Both signal bells will then sound until they are
placed out of operation by operating the switch.
The controlling hand A2 may be set in the direction of the hour hand from "o"
to the Figure XI., to any desired hour and minute; in setting the said hand from
a former position into a new position (backwards or forwards) the above-described
operation must always be effected. The exact setting of the control hand can be
readily effected with the aid of suitable divisions in quarter hours and minutes
provided on the dial.
The arrangement of the adjustable contact a7 offers on the one hand, the advantage
that it can be set by means of the control hand A2, to any desired controlling time
only by the person authorised to do so, whilst, on the other hand, abuse by un-
authorised setting of the control hand by the person who operates the switch I is
completely prevented, because, in consequence of the space 12 in the contact wheel A¹,
the control hand can be moved back by means of the switch only to the "o" point,
and never beyond it. Further, by the arrangement of the adjustable contact a and
in consequence of the condition that the control hand A² must always be returned
to "o" in order to stop the signal or both signals, the advantage is gained that the
signal of the hell D sounds at regular intervals of time, so long as the control hand is
set for one and the same controlling time.

page_text: I, HANS REICH, of Obsplatz 6, Bozen, Tyrol, Austria, Clock Maker, 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 to a clock which is connected with electric signal bells, and
which causes, at any desired and predetermined time, the sounding of an electric
alarm signal, and if this signal is not stopped in due time, puts into operation, after
a desired predetermined interval of time, a second signal which is situated at a
distance from the clock.
The clock has for object to remind a person in a certain place (for example, a
boiler attendant or a boiling master) by means of a bell signal which sounds at
a determined time, that some particular operation is to be performed. It is the duty
of the said person to stop the said signal at once, because if it is not stopped, either
through his neglect of duty or through illness or other accident that may have
happened to him, a second alarm bell, which serves as a check, and may be, for
example, arranged in the manager's or the foreman's office, will sound, and thus give
notice in good time that the first signal has not not been obeyed, or could not be
obeyed, and that therefore measures must be taken to bring aid in order, should an
accident have happened, to prevent interruption of working, or to obviate in time the
occurrence of damage.
In order that the said signal may be given, there is arranged in the clock a contact
piece, which is moved together and simultaneously with the hour hand and can be
set. by means of a special hand, and which constitutes one end of an electric conductor
and closes a circuit leading to an alarm bell by the raising of a contact lever, which,
if the contact is not at once broken by means of a switch, closes, by coming into
contact with a second contact-lever, a circuit leading to a second alarm bell, the
interval of time between the making of the two contacts being capable of being pre-
determined as desired within certain limits by means of an adjusting lever acting
upon the second contact-lever.
The drawings filed with my Provisional Specification illustrate a check clock con-
structed according to this invention.
Fig. 1 shows the clock in front elevation with front portions removed and indicates
the connexions of the respective electric signal-bells and also, in dotted lines, the
dial and hands.
Figs. 2 and 3 are respectively vertical and partial horizontal sections of the
clock.
Fig. 4 is a rear elevation of a contact wheel with the adjustable contact piece,
and
Fig. 5 is a side elevation of these two parts together with the check hand.
Figs. 6 and 7 are elevations of the contact mechanism before and after the setting
of the adjustable contact piece.
As shown in Figs. 1 and 2, a wheel A¹, provided with a sleeve a¹, is placed upon
the hour tube a of any suitable clockwork A, and is engaged, by means of a spring a
entering a groove in the hour tube, in such a manner that it can be rotated freely on
the hour tube by means of the check hand A2 (which is connected with the sleeve a¹)
but is held so firmly that during the movement of the hour hand as it is moved along
by the hour tube and with the hour hand.
In the rim of the wheel A¹, there is let in, so as to be capable of rotation, a ring a³

page_text: (Fig. 4), which is retained by plates a* and is provided with a projecting contact-
piece a that is formed in the centre with a slot aª.
For the purpose of holding the contact piece fast during the setting of the check
hand A in relation thereto, there is employed a lever H, which is pivoted at h to the
front plate of the clockwork, and the arc-shaped arm of which engages with its
hooked end in the notch a of the contact piece a7 as soon as the lever H is, by means
of a pin h (Fig. 3) projecting out through the clock casing, engaged and raised (see
Fig. 6), whereupon the check hand can be shifted as hereinafter described without
moving the contact piece.
The current is supplied to the contact piece a' from a battery B through a
conductor b connected to the clockwork A and through a rubbing spring 61 bearing
on the wheel A¹ (Fig. 1).
On a stud c¹ secured to a vulcanite plate c attached to the front plate of the
clockwork A there is mounted a contact lever C which in the position of rest
(Fig. 1) is kept bearing against a stop-pin c3 by a conductor c², which is in part
formed as a coiled spring.
The conductor c² of the contact lever C leads to the alarm apparatus D (Fig. 1),
which is situated in the same room as the clock, and whose return conductor 62
is connected to the battery B. When the contact lever C and the contact
piece a are in their normal position, the circuit of the alarm apparatus D is
interrupted, but it is closed and thereby caused to sound the alarm when the
contact piece a' has been moved forward by the hour tube to such an extent
as to come into contact with the nose ct of the contact lever C.
Above the contact lever C there is pivoted to the vulcanite plate c like the laver C,
a second contact lever E, which is pressed down against a stop pin e¹ by a conductor e,
which is in part formed as a spring.
When the two contact levers C and E are in their position of rest, the circuit of
the conductor e is also interrupted. The conductor e leads to the signal bell D¹ that
serves as a distance signal and is situated in a room at a distance from the clock, and
whose return conductor e* is also connected with the battery B. When the contact
lever C is raised by the movement of the contact piece a' on the inclined nose c' of
the lever C, then as soon as the lever C touches the nose e of the contact lever E,
the circuit be is closed, and the signal bell D¹ is set going. The amount of the
distance of the contact lever nose e³ from the contact lever C determines the interval of
time which elapses between the sounding of the first signal bell and the sounding of
the second signal bell.
For the purpose of enabling this interval to be predetermined as desired-say, for
example, from 1 to fifteen minutes-the lever H is provided near its pivot h with an
arm h³ which carries an insulated pin * upon which the contact lever E bears. The
free end of the lever H bears with its pin 2 upon a cam h³ mounted, so as to be
capable of rotation, on the clock casing. According as the pin h bears on the lowest
point or on the highest point (marked "O") of the cam h5, the lever H is depressed
or is raised (see Fig. 7), whereby the contact lever E is moved in such a manner that,
in the first case, the distance between the two contact levers C and E, and con-
sequently also the interval of time, is increased, whilst in the other case, the contrary
happens.
The operation of setting the contact piece to give a signal at a predetermined
time by means of the bell D is as follows:-
When the clock is in its normal position (Fig. 1), in which the check hand A2 is
at zero, the contact piece a is situated only at such a distance from the nose c¹ of
the contact lever C as is just necessary to prevent the circuit from being closed.
Let it be assumed that the check clock is to be set so that the signal of the bell D
will sound exactly two hours after the time indicated by the position of the hour
hand at the time being.
For this purpose, the check hand A2 is advanced slowly in the direction of the hour
hand, until the signal is given by the bell D, whereupon by raising the lever H its
forward end h¹ is booked into the slot aª of the contact piecé a', whereby the latter is

page_text: held fast (see Fig. 6). The check hand A2 is now brought from the zero position to
opposite the figure II of the clock face; the contact wheel A¹ is rotated with it, but
the contact piece a7 is held back in the wheel A¹ and remains behind by the amount
of the angular rotation of the hand A2. The lever H is then released and pressed down
by the spring h (Fig. 1), and the contact piece is therefore released.
The check hand A2 is now put back to zero, whereby the contact piece a7 is moved
away to a corresponding extent from the nose ct of the contact lever C (see Fig. 7).
Unauthorized adjustment of the check hand is prevented by closing in the hands
of the clock by means of a glazed cover F, which can be fastened with a lock G
(Fig. 2), and which also covers in the cam h³.
When, during the working of the clock, the contact wheel A¹ and the check
hand A2 are moved forward by the hour tube a¹ through the amount of two hours,
the signal bell D is caused to sound in the manner above described.
For the purpose of enabling the first signal (or both signals) to be at once stopped
by means of the check part, the clock is provided with a vertically movable switch I
(Figs. 1 and 2), which is pressed down by a spring i, and engages, by means of its
operating pawl 21, the teeth of the contact wheel A¹, and, on moving upwards, moves
back the check hand A'. The check hand is prevented from being rotated backwards
beyond the zero point by the switch I, by means of a space 2 which is formed in the
toothed periphery of the contact wheel, and which, when the check band A2 has been
set back to zero, is entered by the pawl i¹, which thus comes out of gear with the teeth
and is consequently unable further to actuate the contact wheel-A¹.
So long as the check hand A2 is set to a determined hour in relation to the contact
piece a', the signal will, when the said hand has been returned to its zero point after
the signal has been given, again sound on the expiration of the predetermined
interval of time.
The duration of the sound of the signal is determined by the width of the contact
piece a7.
If the alarm apparatus D is not at once thrown out of operation, the second alarm
apparatus D¹ will sound after the interval of time which has determined by the ad-
justing mechanism h³, H, h. Both signal bells will then sound until they are placed
out of operation by operating the switch.
The check hand A2 may be set in the direction of the hour hand from zero to the
Figure XI, to any desired hour and minute; in setting the said hand from a former
position into a new position (backwards or forwards) the berein before described
operation must always be performed. The exact setting of the hand A2 can be
readily effected with the aid of suitable quarter hour and minute divisions provided
on the dial.
The arrangement of the adjustable contact piece a7 offers, on the one hand, the
advantage that it can he set, by means of the hand A2, to any desired cbecking time
only by the person authorized to do so, whilst, on the other hand, abuse by un-
authorized setting of the check hand A3 by the person who operates the switch I is
completely prevented, because in consequence of the space in the contact wheel A¹
the check band A² can be moved back by means of the switch only to the zero point,
and never beyond it. Furthermore, by the arrangement of the adjustable contact
piece a7 and in consequence of the condition that the check band A must always be
returned to zero in order to stop the signal or both signals, the advantage is gained
that the signal of the bell D sounds at regular intervals of time, so long as the check
hand is set for one and the same checking time.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A check clock or alarm signal apparatus comprising a contact wheel A¹ which is
moved by and with the hour hand, can be set back to zero by means of a check
hand A3, and is provided with a contact piece a which is adjustable in the said
wheel; a lever H, h¹ serving to hold the contact piece a' fast during setting; and

page_text: two contact levers C and E, of which one is arranged above the other, and which are
connected with the conductors of electric sounding apparatus D and D¹ respectively,
so that when the contact piece a' comes into contact with the lever C, an alarm signal
is sounded, and if the said signal is not stopped, a second alarm signal is sounded
after a certain interval of time in consequence of the production of contact between
the two contact levers C and E.
2. In a check clock or alarm signal apparatus according to Claim 1, for stopping
the sounding apparatus D or D¹, and for again setting the check hand to its zero
point that is to say, setting the part a-a movable switch which is kept depressed
by a spring i and which, when raised, engages, by means of its operating pawl ¹, in
the toothed periphery (which is provided with a space 2) of the contact wheel A¹,
whereby the said wheel is rotated, and the check hand A2 is set back to zero.
3. In a check clock or aların signal apparatus according to Claim 1, for setting the
contact lever E so as to produce a determined interval of time between the two con-
tact makings, an adjustable cam h5 upon which bears the pin h² of the lever H whose
arm h³ carries an insulated pin h that serves as a support to the contact lever E, so
that the contact lever E can be moved nearer to or further from the contact
lever C, and the interval between the two contact makings varied, by operating the
lever H.
4. Check clocks or alarm signal apparatus constructed, arranged, and operating
substantially as herein before described with reference to and shown in the drawings
filed with my Provisional Specification.
