This Invention relates to an improvement in automatic electric time signaling
apparatus, the object being to combine with any approved time mechanism an
electric signaling apparatus which shall be operated by and in unison with the time
mechanism, and shall be of such construction and arrangements of parts that it will
actuate one or more signals automatically at any predetermined periods of time
throughout the twenty four hours of each day. To this end the Invention
consists, first, in the combination with a time piece provided with mechanism for
breaking an electric circuit at any regular intervals of time of a motor actuated
by spring, weight, water, or other power; a wheel furnished with stop pins corre-
sponding in number to the number of minutes in twenty four hours, said wheel
being revolved by the motor; a circuit closing device connected with the signaling
devices and adapted to close the circuit at any moment of time iudicated on the
wheel, the stop pin corresponding to the time of sounding, the signal being.
withdrawn to allow of the automatic closing of the circuit; an armature connected
at one end with the circuit closers and electro magnets located in the circuit
embracing the time mechanism, and adapted to regulate the movement of the stop
pin wheel and cause the motor connected therewith to impart an intermittent
rotary movement thereto, and move it through a space equal to the distance between
any two adjacent stop pins, shewing each moment of tine as indicated by the time
mechanism. This Invention further consists in the combination with a wheel or
cylinder provided with any desired number of removable stop pins and mechanisin
for revolving said wheel in unison with a time piece or regulator of two or more
circuit closers located in the electric circuit embracing the signals, said circuit
closers being arranged to close the circuit at any moment of time during the twenty
four hours of the day by removing the stop pin designating the minute at which
it is desired to sound the signal. This Invention further consists in a wheel
provided with a continuous row of stop pins extending around the wheel any
desired number of times in a spiral form or line, of an automatic circuit closer and
mechanism for moving said circuit closer transversely across the periphery of the
wheel or cylinder. This Invention further consists in an automatic electric circuit
closer forming a part of my signaling apparatus. By passing the electrical current
flowing from the time measuring mechanism of the signalling apparatus to the
signal gong thereof, through the interposing medium of the circuit closing device,
I am enabled to modify the electrical current in such manner that, as a result, I
obtain a series of intermittent signals following each other in quick succession,
automatically operated, and not before obtained by the employment of electrical
forces. This Invention further consists in the several other combinations of parts
and features of construction, as will be hereinafter described and pointed out in the
claims. In the accompanying Drawings, Figure 1 is a plan view of the improved

To
pendulum type of movement, and of any desired form of construction.
the clock-case are attached binding posts u, a¹, to which are attached the
ends of the wire B of the main circuit, and- thus. inclule the clock movements
therein. To one binding post a is attached a short wire b, the opposite end
of which is secured to a screw b', which serves to secure one end of the
metal strip to block b, the opposite end of the metal strip b being held in place
by means of a screw b', which extends through the block and forms a contact point 65.
To the binding post a' is attached a short wire c, which is secured at its opposite
end to a metal strip c¹ by means of a screw c², the metal strip c¹ being connected at
one end to the plate c³, to which latter is hinged a metallic arm c, which is held in
contact with the contact point 6 by means of a light spring. The free end of the
spring pressed arm extends within the plates of the clock movement in close
proximity to the first pinion C, which is furnished with a cam C. As the opinion C
makes one revolution every minute of time, the cain C¹ operates to lift the outer
end of the arm c* once every minute, and consequently breaks the electric circuit
by moving the metallic arm away from the contact point 6. In order that the
circuit may remain broken but an instant of time, or for only a small fraction of a
minute, the arm c¹ is provided with a longitudinal slot, thus forming a narrow
transverse strip on the end of the arm with which the can engages. Thus it will
be readily understood that the clock mechanism operates to automatically break the
electric circuit during every successive minute of time. I have only illustrated one
form of device for accomplishing this effect, but it is evident that other devices may
be employed for this purpose, and many changes may be resorted to for the purpose
of adapting the automatic circuit breaker to different forms of clocks, and hence I
would have it understood that I do not restrict myself to the particular mechanisın
shown and described for automatically opening and closing the circuit by the time
mechanism of a clock. The ends of the wire B, which connect with the clock, are
attached to the screws or binding posts D, D', connected with the case of the time
signalling apparatus. D, D³, are electro magnets, the wire of one helix D
connecting with the wire B by the wire d, and the wire of the other helix D

page_text: connecting with the battery wire E of the main circuit, and also leading to all the
bells or signals. The other battery wire F connects with the other end of the wire B
leading to the clock, and from thence runs to the switch board E, and is attached to
the screw Es which connects with the battery, while to the screw E is connected
the wire E*, which connects with a metal strip F¹ attached to the rear side of the
circuit closer frame G. Switch lever K may be shifted to close the electric circuit
through the hand buttons on knobs I, I, I, which latter are placed in electrical
connection with the several different signals, in order that the signals may be
operated by hand in the event that it is required to signal the departure of late or
special trains, or for purposes not contemplated by the regular schedule time for the
running of trains. Within the case of the signalling apparatus is placed a motor J,
which may be of any desired construction and operated by a weight J', or by a
spring or water or other power. When a weight or spring is employed an opening f
is preferably made in the case for the reception of the squared end of the shaft on
which the cord fis wound, in order that a key may be applied for winding up the
motor, which latter may be constructed to run cight days or longer without
rewinding. To the frame of the motor, or to any other suitablo support, is pivoted
a stop lever K, one end of which is provided with a hooked projection K¹, which
enters an opening in the frame of the motor and intercepts the fly K² of the motor,
thereby serving to instantly stop the motor when the hooked end of the lever is
allowed to move across the line of travel of the fly or fan K². A spring / sorves to
hold the lever K in a position to retain the motor against movement until the lever is
moved in the opposite direction in opposition to the force of said spring. L is an
armature lever pivoted to a block or plate 7, the shortarm of the armature being raisod
by a spiral spring . The long arm of the armature has connected therewith, by a
link or other suitable device, an oscillating bar L', the outer end of which is provided
with a slot L for a purpose hereinafter described. M is a stop pin wheel of any
desired size, and formed of any suitable material. The stop pins N may be arranged
on the wheel in different ways according to the size of the wheel and size of the
stop pins. In the construction of apparatus in which I have illustrated this
Invention, the wheel M is provided with three hundred and sixty driving pins N'
projecting outwardly from the side of the rim N³, said pins N being secured at
exactly equal distances apart, and serving as cogs for the engagement of the
worm or spiral cam N³ attached to the shaft N, the latter being revolved by means
of a toothed wheel N³ attached thereto, which meshes with a toothed wheel No of
the motor. Hence it will be observed that the stop pin wheel is moved through a
space equal to the distance between two of the pins N¹ at every completo
rovolution of the shaft N. To the shaft N is secured a cam O, which engages
with the outer end of the oscillating bar or rod L¹, and as the shaft revolves the
cam serves to raise the bar and the long arm of the armaturo until the latter
approaches sufficiently close to the electro magnets to be attracted and held up
thereby so long as the circuit is closed by the clock movement. Shaft N' is
also provided with a disk O', having an opening O' formed therein. The
lower end of the stop lever K rests against the side of the disk, and thus is
prevented from engaging with the fan or fly of the motor and stopping the same
until the disk has revolved and brought the opening 02 to register with the end of
the lever, allowing the spring k to throw the lower end outward through the
opening O* in the disk, when the upper hooked end is engaged with the fly, thus
stopping the motor. When the clock movement breaks the electric circuit the
armature is released from the electro-magnets and falls, the outer end of the
armature lever striking the inclined edge or surface o on the stop lever K, thereby
operating to withdraw its hooked end from engagement with the fly or fan and
starting the motor, which in turn revolves the slotted disk O¹, and causes the latter
to retain the stop lever from contact with tho fan of the motor throughout another
revolution of the shaft N'; hence the clock movement operates to automatically
break the circuit, and release the armature once every minute. The release of the
armature serves to start the motion in operation, and the latter imparts a movement

page_text: to the stop pin wheel equal to the distance between the pins attached to its rim,
and when said wheel has been moved the required distance the motor is auto-
matically stopped and retained at rest until the clock has recorded another moment
of time, when the circuit is again broken and the operation repeated. The
periphery of the stop-pin wheel is provided with two sets of stop pins, each set
consisting of one thousand four hundred and forty three stop pins, which are
arranged in a continuous spiral surrounding the wheel, and forming four rows of
pins. As there are one thousand four hundred and forty minutes in the twenty
four hours of a day, it will be observed that each set comprises a stop pin for each
minute of the day, and also three extra pins for a purpose hereinafter described.
If it is desired to actuate but one signal one series of stop pins will suffice, but
when it is necessary to operate two or more separate and independent signals, as
for instance, to indicate the departure of trains going east and trains going west,
then two independent series of stop pins, as illustrated in the Drawings, are
required. Additional series of stop pins can be provided by increasing the width
of the periphery of the wheel. Stop pins N may be formed of any desired material
and be made with sharp points to be inserted in holes formed in the periphery of
the stop pin wheel; or the stop pins may be made in the form of screws to be
removably secured in the periphery of the wheel. G is a frame attached to the
case of the apparatus, and located above the stop pin wheel. The outer cross bar p
is provided with a down hanger P², which is preferably made laterally adjustable
by means of the attaching screws p¹ entering the elongated slots p² formed in the
upper end of the plate of the down hanger. The lower end of the down hanger
is provided with a bearing p³, in which is journalled one end of the shaft N'. The
side bars p* of frame G are provided with track ways or guides p³, upon which is
supported the reciprocating circuit closer carriage Q, the sides of the latter resting
upon said track ways or guides p³. Upon the inner faces or sides of the guides p
are placed the metallic strips F, F. The metal strip F is employed when the
apparatus is designed to work on an open circuit, and strip F³ whon used for
working on a closed circuit. Metal strip F projects slightly above-the-surface of
the trackway, to which it is attached, a slot being formed in the cross bars q of the
reciprocating frame or carriage Q to receive the upwardly projecting edge of the
metal strip As heretofore stated the metal strip F is attached to the metal
strip F¹ secured to the rear side of the frame G, and the latter connected with the
battery wire E, whereby both metal strips F and F are embraced in the electric
circuit. Reciprocating frame or carriage is furnished with four hinged or
pivoted circuit closers R, R', R2, R3, each of which has secured to its outer or free
end a metal plate R*, which rests upon the upper edge of the metal strip Fª when
the circuit closers are depressed to their lowest position. To the plates R+ are
attached the ends of the flexible conductors t³, t,, t, by means of screws 2 on
other suitable devices, said flexible conductors being preferably inserted through
the eyes or loops 75 formed in the upwardly projecting arms 7. To the ends of
the reciprocating carriage Q are secured the standards 7, in the upper ends of
which are journaled the ends of an elongated crank S, which latter bears against
the several arms .. By raising the crank S all the hinged circuit closers are
raised simultaneously. To the end of the crank S or formed integral therewith is
connected an arm S¹, which engages with the underside of a rod S² secured
between the arms 8, 8', of the short arm of the armature lever. The rod 8² is of
sufficient length to accommodate the arm s' of the reciprocating closer carriage
throughout the distance through which it travels. The short arm of the armature
being depressed operates to depress the arm s', and raise the soveral hinged or
pivoted circuit closers, the hinged circuit closers of each set being so constructed
that their stop pins T, T, will be in line with each other for a purpose
hereinafter described. A yielding metal strip T is attached to the central
cross bar of the reciprocating carriage Q, and beneath the hinged circuit
closers is provided with a cross piece T2, whilst the free end Ts projects
outwardly beneath the metal strip F. When the hinged circuit closers are

page_text: raised the resiliency of the metal strip T' operates to throw the free end
thereof in contact with the metal strip F3 connected with the battery and close the
circuit, and when the oircuit closers are depressed they operate to force the yielding
circuit closer T¹ out of contact with the metal strip F³ and thus break the circuit.
All of the several flexible conductors to, t, t, are provided on their outer or free
ends with the open slotted metal tips t, which are perforated at t¹ for the attachment
of the conductors, and at their opposite ends provided with the open slots t so that
they may be readily inserted beneath the head of the screws t connected with the
signals by electric conductors, and placed in the circuit by tightening the screws.
The conductor to connects with the two conductors ts, to, which connect with the
middle and adjacent hinged circuit closer. The flexible conductor to connects with
the screw or binding post U, with which is connected the wire U₁ leading to the
east three minute bell U2. Conductor to connects with the wire Us leading to the
starting bell Us, and conductor t connects with the wire U leading to the west
three minute bell U. The following is a description of the mechanism employed
for reciprocating the circuit closing carriage:-Upon the axle of the stop pin wheel
is secured a pinion in which measures with a toothed wheel u journalled in a
bracket . The wheel u' having four times as many teeth as there aro cogs in
the pinion u, it follows that it will take four revolutions of the stop pin wheel to
impart a single complete revolution to the toothed wheel u'. To the shaft of the
toothed wheel u¹ is secured a cam w³, against which bears an arm u³ connected
with or formed as a part of the rock shaft us. The upper end of the rock shaft u
is provided with an arm u which presses against one of the standards on the
reciprocating circuit closer carriage. Hence it will be understood that the carriage Q
is caused to travel from one end of its frame to the other once during every four
successive revolutions of the stop pin wheel. A spring b is attached to the case of
the apparatus, the free end of the spring being attached to the reciprocating
carriage. When the carriage has been removed outward to the limit of its travel
by the cam and arms on the rock shaft, the arm engaging with the cam is released
therefrom and allows the spring b to retract the carriage O to its original starting
place. To the case are connected three circuit closers I, I, 12, which are connected
respectively with the several signals by means of the wires w, w¹, w². These last
mentioned circuit closers may be thrown into the battery circuit by means of the
switch, and thus enable the signals to be operated by hand and used when trains
are late or "special," or at any time when the suspension of the regular signals is
desired without making any change in the time or stop pin wheel. As heretofore
stated, each set of stop pins on the periphery of the wheel is composed of four spiral
coils, being one thousand four hundred and forty three, or three in excess of the
number of minutes in the twenty four hours in the day, and hence the stop pin
wheel makes four revolutions during every twenty four hours. The rim of the
stop pin wheel is divided arbitrarily into any desired number of sections. In the
present form I have divided it into six sections, each section representing a
particular hour of the day. In each of the six sections there are sixty driving pins
secured to the rim of the wheel, and these pins are numbered from left to right,
from zero to fifty nine, thus furnishing a driving pin for each minute of the hour.
The stop pins on the periphery of the wheel are arranged to correspond with the
driving pins, that is to say, in each one of the six sections on the periphery of the
stop pin wheel there are four rows of stop pins for each independent set of driving
pins; on each row there are sixty pins, excepting in the last section of the set there
are sixty three pins, which is necessary, as will hereinafter be described. The four
sections of pins of sixty in a row, corresponding with the section of driving pins
on the rim of the wheel represent four different hours of the day, that is, the first
section of the set corresponds with the hour of twelve at night, the next outer section
denotes the hour at six a.m., the next outer section twelve a.m., and the outer section
six p.m. Having described the construction and arrangement of parts of this.
Invention I will now proceed to describe its operation. The apparatus having
been properly set up and the connections made by the different wires hereinbefore

page_text: referred to, the clock operates to open and close the electric circuit during each
successive moment of time. We will now assume that the apparatus is to be used
to automatically actuate the two signals for a train going east and a train going
west, that the schedule time for the departure of the eastern train is 12.45 p.m.
and the schedule time for the departure of the western train is 3.18 p.m. The stop
pin wheel is then set as follows to actuate the required signals:-For the eastern
bound train it is necessary to withdraw the forty-fifth stop-pin, counting from
left to right in the third tier or row of pins, counting from the rear face
of the periphery of the wheel toward its centre, and in the first section of
pins corresponding with the driving pins on the rim of the wheel. The first
section of pins is denoted by the letter a, and hence the pin that must be withdrawn
is located in one of the four rows of stop pins corresponding to said section,
as that portion of the periphery of the wheel embracing section x passes
beneath the circuit closers between the hours of 12 a.m. and 1 p.m. Again it
will be observed that the row of pins which passes beneath the circuit closers
between the hours of 12 a.m. and 1 p.m. is the third row, counting from the rear
sido. of the wheel toward the centre, on the row designated by x¹. The forty
fifth pin in that row is designated by, and hence the latter pin must be
withdrawn, and the stop pin wheel is properly set to automatically actuate the
signal for the departure of the eastern bound train leaving at 12.45 p.m. It is
now necessary to set the stop pins for actuating an independent signal for
indicating the departure of the western bound train at 3.18 p.m. It will be
observed that the pin to be withdrawn is in the third section x on the stop pin
wheel, and is in the third row of pins, counting from the centre to the front, or in
row, and is the eighteenth pin, counting from the left to the right, in the first
section, said pin being designated by the letter y. In order to properly set the
stop pin wheel, so that it shall revolve in unison with the clock movement, or to
allow the stop pins to be changed to correspond with any alternation in the
-schedule time, the adjustable bearing in which one end of the worm shaft N is
journalled is loosened and the shaft removed, thus enabling the required stop pins
to be withdrawn or inserted. Then the stop pin wheel is adjusted on its axis
and the shaft N placed in position, and the actuating worm fixed thereto is
inserted between the driving pins, which correspond with the next succeeding
minute of time as indicated on the dial of the clock movement. As the clock
movement breaks the circuit at the next succeeding moment, the motor will be
automatically started and move the stop pin wheel in unison and in perfect timo
with the clock. It will now be assumed that the stop pin wheel is started at 12 p.m.
(at night). At every moment of time the clock mechanism operates to open and
close the electric circuit in which the electro magnets D³, D³, are located. As the
circuit is broken the long arm of the armature L falls, while the short arm rises
and allows the hinged circuit closers to drop; the pins attached to the underside of
the hinged circuit closers fall upon the ends of the stop pins, and thus prevent
the closing of the circuits between any of the circuit closers and the metal strip
attached to the frame supporting the reciprocating carriage Q in which the circuit
closers are hinged. It will be observed that to close the circuit from the battery
to any of the signals through the hinged circuit closers, it is necessary that the
latter shall drop a suflicient distance to establish a contact between the metal strip
on the frame and the metallic plates or strips attached to the hinged circuit closers.
The stop pins on the wheel serve to prevent the closing of the circuit, and it is
only when a stop pin has been removed that the circuit closers are allowed to fall
and close the electric circuit. At the same time the short arm of the armature is
raised its long arm falls and strikes the inclined surface or edge on the stop
lever K, withdrawing the latter from engagement with the fan or fly of the motor,
and allowing the latter to start instantly and revolve shaft N. As the shaft N⭑
revolves, the slotted disk thereon serves to retain the stop lever K out of
engagement with the gearing of the motor, while the cam on the shaft serves to
gradually raise the armature and depress the arm connecting with the hinged

page_text: circuit closers, and raise the latter from contact with the stop pins. As the
armature approaches the electro magnets, the latter attract the armature and hold it
in contact with the cores of the magnet until the circuit is again broken by the clock
mechanism. The shaft N' as it revolves operates through the worm disc to impart
an intermittent rotary movement to the stop pin wheel, and thereby move the
next succeeding stop pins beneath the pins of the circuit closers. It may be here
mentioned that the time consumed by the motor in moving the stop pin wheel is
only a fraction of a moment, so that the wheel remains stationary a portion of the
time. The apparatus continues to be operated automatically in the mannor above
described, the wheel being moved a distance equal to the space between the two
adjacent pins on the stop pin whicel once every successive minute. As the hinged
circuit closers must be retained in such relative position that the pins secured
thereto will fall squarely upon the ends of the stop pins, it follows that the circuit
closers must be moved transversely across the periphery of the wheel, that tho
circuit closers may exactly register with the spiral rows of stop pins on the wheel.
This transverse reciprocation of the circuit closers is effected by a rock shaft and
cam mechanism, hereinbefore described, which insures the perfect registry of the
pins on the hinged circuit closers with the spiral rows of stop pins during every
portion of the revolution of the stop-pin wheel. The continued and successivo
opening and closing of the electric circuits by the clock operates, as herein before
described, to raise and let fall the circuit closers, and to revolve the stop pin wheel
step by step, and this operation is continued until the stop pin wheel has revolved
and brought that portion of the wheel from which the stop pin located at x has
been withdrawn, which space is located directly beneath the pin T of the hinged
circuit closer R. The stop pin wheel is adjusted so as to reach this point in its
revolution at exactly 12.42 p.m., and as the clock mechanism registers the
particular time the circuit is broken and all the hinged circuit closers allowed to
fall. All of said circuit closers, with exception of circuit closer R, having each a
stop pin to support them will therefore be held out of contact with the metal plate F³,
while the stop pin in line with circuit-closer R having been withdrawn, allows
the circuit closer R to fall a greater distance than the others, so that the inctal
plate attached thereto will rest upon the edge of the metal plate F, thus
closing the circuit from the battery through the hinged circuit closer R
through its flexible conductor t and wire U¹ and sound the bell M at 12.42 p.m.
or three minutes before the departure of the train going cast. The electric
circuit is then automatically closed and broken, as before, until the vacant space
at ² registers with the pin T attached to the hinged circuit closer R³, the pins
operating with the two circuit closers R and R' being located at such distance
apart that three minutes will elapse between the sounding of the first and
second alarms, and hence at three minutes subsequent to the sounding of the first
alarm, or at 12:45 p.m., the circuit closer R' falls and closes the circuit and
establishes a connection with the starting bell Us and sounds the latter, denoting
the starting time of the east bound train. While I have arbitrarily fixed upon
these particular signals, it is evident that they may be modified at pleasure. While
I have described the operation of the devico to signal the departure of only one
east bound train in every twenty four hours, it will be understood that the set of
stop pins for operating the signals of the east bound train will be adjusted
according to the number of trains going east every twenty four hours, so that the
signal or bell, one or more placed in the waiting room or rooms of a railroad
station, will automatically signal the departure of the train, and also give any
desired cautionary signal that passengers may be in readiness to board the train.
The stop pin continues to revolve, and in the same manner closes the circuit
between the hinged circuit closers R² and R³, and metal strip F², and sounds the
starting and cautionary bells for the western bound train. Any desired number of
separate signals may be employed and operated with the utmost accuracy and
precision. The stop pins in the wheel may be readily adjusted to correspond with
schedule time for the departure of all the trains leaving any particular station. The

page_text: separate and independent sets of stop pins enable the apparatus to operate separate
signals to indicate the departure of trains going cast and west or in other different
directions, and the signals will be operated with perfect accuracy without the necessity
of any attendant. At a union depôt, where trains are leaving on different roads or
in different directions, the stop pin wheel should be provided with as many sets of
stop pins as there are different branches of road over which different trains pass
in leaving the station, so that separate and independent signals can be employed
for denoting the leaving time of the several trains. As heretofore stated, there are
one thousand four hundred and forty three stop pins, or three more stop pins than
there are minutes in the twenty four hours of a day. The three extra stop pins
are furnished for the following purpose:-If it is desired to sound a starting signal
at 11.59 p.in., the proper pin is withdrawn, and as the warning pin on the circuit
closer, which is situated forward of the starting pin a distance corresponding to
three minutes of time, falls into the space and sounds the three minute signal, the
wheel then turns, and were it not for the extra stop-pins the warning-pin would
would have no support and hence would keep sounding the signal, but by providing
the three extra stop pins the warning pin is provided with supports to allow of the
regular automatic action of both the warning and starting pins on the circuit
closers. When the starting-pin has dropped on the 12 p.m. stop pin it is then
automatically moved transversely across the row of stop pins at the next movement
of the stop pin wheel, and falls upon the stop pin indicating 12-01 a.m., and the
warning pin upon stop pin 12.04 a.m. In the foregoing description I have set
forth the mechanical construction and practical application of the time measuring
mechanism of my signalling apparatus, to the complete understanding of which it
now remains only to set forth the detailed construction and operation of the
automatic signal circuit closer shown in Figures 16, 17, 18, 19, and 20 of tho
accompanying Drawings. The object of this device, as hereinbefore stated, in the
modification of the electric current after it leaves the time measuring mechanism on
its passage to the signal gong in such manner that as a result a series of inter-
mittent signals following each other in quick succession is obtained. With this
end in view I have devised a signal circuit closer, consisting essentially in a train,
verge, vibrating hook, swinging armature, electro magnets, notched disk, circuit
closing wheel, insulated spring, contact points having electric connections, a motor
to actuate the train, the escapement of which is controlled by the said electro
magnets, an electric connection between the circuit closer and time mechanism and
connection between it and the electric gong, which latter the circuit closer influences
to produce a series of intermittent signals. Referring to the Drawings, of which
the Figures 16, 17, 18, 19, and 20 illustrate the signal circuit closing device, letter
A10 represents a standard upon which the component parts of the circuit closing
device are mounted. B, B, posts supporting the motor, train, escapement and
signal circuit closing mechanisin; C, C, a pair of electro magnets, and 110 an
armature energized thereby; A", B12, C, and D", are binding posts through which
connection is made between the circuit closer and time signalling apparatus, and
A", D, are binding posts connecting the circuit closer with the electric signal
gong As The train supported in the frame plates H", H, consists of wheel a¹
mounted on the arbour DS and meshing with pinion a", of 610 mounted on
arbor and meshing with the pinion co, of crown wheel do mounted on the
arbor al and engaging with verge b₁, which latter is mounted on the arbor c¹ also
supporting the vibrating hook d". Vibrating hook all is secured to a block a¹³
journalled on the arbor c", and is adapted to engage with a pin al located at the
extremity of the rear arm d of the escapement lover B¹³. The rate of vibration of
said hook is governed by a regulating ball c, which has sliding adjustment
on a rod secured pendulum-wise to the block 3, screw d¹ retaining it in
position at any point thereon. According to a well known principle this ball
is raised or lowered on the rod as it is desired to accelerate or diminish
the rate of vibration of the hook and the consequent motion of the train.
Escapement lever B's, mounted on arbor c¹³, has one arm № in engagement with

page_text: the vibrating hook ", and its other arm Et adapted to engage with peripheral
notches e in the disc F10 mounted on the arbor a, and revolving with the drain
wheel b10. To the underside and midway the length of the forward arm E of the
escapement lever B₁s a bar e¹ is pivoted, to the lower end of which an armature D10
is transversely secured and swinging directly in front of the poles H10, H1, of the
magnets Co, C. The inner faco of tho armature, or that which is presented to
the poles of the magnets, is provided with a thin plate go of any suitable
non electrical substance to guard against the attraction of the armature by the
residual magnetism left in the magnets after their normal discharge and the
consequent accidental actuation of the train. An adjustable screw E, supported
in a post F, serves to regulate the play of the armature D, which, together with
its supporting. bar e, is so hung on the forward arm E10 of the escapement
lever Bis that when the magnets C, C", are vitalized and the armature is attracted
to poles H10, H10, the hooked end of said arm E10 will be raised out of either
one of the notches e in the disc F10 with which it is in engagement, thereby
depressing the rear arm of the lever B¹s and releasing the engagement of the
vibrating hook " with pin a at the extremity of said arm. The vibrating hook
will now be started in vibration and actuate the verge bin engagement with the
teeth of the crown wheel, and the train once set in motion will operate to revolve
the arbor a7, and with it the circuit closing wheel Gto secured to that end of the
arbor which projects through the front plate H" of the train frame. Circuit closing
wheel Go is in this instance provided with six teeth or projections e¹ on its
peripheral face arranged in groups of three at points directly opposite each other,
said teeth or projections operating to raise a spring metal contact point Els mounted
on an insulated bracket F2 secured to the frame plate H", and having current
connection with the battery through the coiled wire b, and close the circuit
between said contact point and the spring metal contact point H superposed upon
bracket F2, insulated from contact point E by insulating plate 10, and having
connection with the signal gong through the coiled wire b. Of the two contact
points E2, H2, the former is the longer, and has its free end which engages in its
normal position with the periphery of the circuit closing wheel bifurcated to
increase its flexibility. The teeth or projections on the circuit closing wheel thus
perform the function of forcing the two contact points in engagement with cach
other, closing the circuit between the battery and signal gong, which will be again
broken as soon as the revolution of the circuit closing wheel from left to right
carries the teeth or projections beyond the range of the longer point E¹², allowing
it to break contact with contact point H¹ and resume its normal position. It will
thus be seen that as often as the two points El and H are in engagement with
each other the circuit will be closed and the bell or gong will sound one stroke or
signal. The number of signals sounded and the length of the interval between
them will thus depend upon the number of teeth on the circuit closing wheel and
their proximity to each other. However the cautionary signals cannot be sounded
through the agency of the circuit closer unless by means of the hand knobs until
the electro magnets Co, C, have been first vitalized to release the train escapement
and thus permit the wheel Go to revolve. The electro magnets C¹º, C¹¹, here used
may be of any approved form of construction, and are supported above the surface
of the standard A10 by a bracket f¹³, connection being made between them and the
stop pin wheel E18 of the time signalling apparatus through the binding post A", a
wire attached to said post passing first to the bobbin C, there forming a helix;
returning it forms a similar helix in the bobbin Co, and is then attached to the
binding post C, through which the current returns to the battery. The motor
employed with the circuit closer to actuate the train may be weight, water, spring,
or other power, but I have used the spring type as the best adapted and most
convenient in this capacity. Spring E¹³ encircles the arbor D¹³, upon which the
wheel A is mounted, and which projects through the plate H" of the train frame,
and is squared so that a key may be applied for winding up the motor. The outer
end of the said spring Es is secured to the upper right hand pillar of the three

page_text: pillars E8, which at once separate and retain in place the plates H12 and E¹ of the
train frame; the spring is further provided with the usual ratchet wheel ƒ",
ratchet g, and ratchet spring". A ratchet cam 110, having engagement with a
pin R¹ located on the ratchet wheel barrel J, rigidly secured to the arbor D¹³,
serves to prevent the spring from being wound too tightly. The notches in the
cam 110, of which there are a limited number, are arranged to engage with the
pin 10 at each revolution of the ratchet wheel f¹; when now the spring is wound
sufficiently tight all of the notches in the cam will have been presented to
the pin and passed, and the pin 10 in its next revolution will come in contact
with the periphery of the cam and the key will be prevented from further turning.
As the spring runs down the motion of the ratchet wheel barrel will be reversed,
and the pin will engage with the notches in the cam from beneath, and finally
restore it to its first position. Having thus described the mechanical construction
of my circuit closer, to a more completo understanding of its operation it becomes
necessary to give a description of its working when employed in connection with
the time signalling apparatus, and when under the influences of electrical forces.
It might here be well to observe that it is an established custom with railway
companies to sound a cautionary signal at a certain time determined upon and
announced by them, before the departure of every train, and also a starting signal
at the exact time of starting. Some companies may for instance announce that
five minutes before the departure of all trains, a cautionary signal of five bolls
following in quick succession will be sounded, and another signal of one bell be
sounded at the exact moment of starting other companies may agree to sound as
a cautionary signal two bells two minutes before the departure of each train, and one
bell at the exact moment of departure; but the signal fixed upon by a majority of
the railway companies is the sounding of three bells three minutes before starting
time, and one bell at that moment, and it is to this particular signal that my
device as herein shown is adapted, although it is evident that by increasing or
decreasing the number of teeth on the circuit closing wheel, any desired number of
signals may be sounded. To effect such changes the teeth-may be made removable,
or several wheels cach having a different number of teeth or projections may
accompany cach machine. My time signalling apparatus described in United
States Patent, No. 229-92, as now constructed, only partially accomplishes
signalling purposes. It is true that it is capable of sounding at any desired instant
a cautionary signal, such signal consisting in one single stroke or sounding of the
gong, but in its present form it admits of no intermittent signalling. This difliculty
is completely overcome by the employment of the improved circuit closer herein
described as an interposing medium through which the current must pass before it
reaches the signal gong, the circuit closer operating to modify the current in
such manner, that any variety of intermittent signals may be given. Referring to
the diagram, let A represent the case to contain the stop pin wheel with all its
parts removed, except the wire connections. Assuming now that a pin on the stop
pin wheel representing the moment of time at which it is desired to sound the
intermittent signal has been withdrawn therefrom, thereby allowing the hinged
circuit closer of the time wheel to drop a sufficient distance to establish a contact
between the metal strip on the frame and the metallic strip or plate attached to
the hinged circuit closers. The circuit will thus be closed between plate 01° and
point on the diagram, and the electric current will flow through wire ell to
binding posts A", from thence to electric magnet, from thence to magnet Clo
returning to the battery through binding post C¹². In this passage of the electric
current the magnets are vitalized, and they in turn magnetize and attract to their
poles H10, H1, the swinging armature D, the movement of which will raise the
hooked arın E⁰ of the escapement lever out from either of the notches el in the
disc F10 as the forward arm of the lever is raised the rear arm will be depressed,
the engagement of the vibrating hook therewith will be released, and the hook
started vibrating; the verge will now engage with the different teeth of the crown
wheel, and the train will be started in motion and operate to revolve the circuit

page_text: closing wheel, which is adjusted to perform a half revolution at every closing of the
circuit bo, o, and to stop in such position, that as soon as it is again set in motion,
a tooth will immediately operate to raise the spring contact point E¹³, connected
with an independent current from the battery through coiled wire 6 entering the
circuit closer by way of binding post D", and bring said contact spring E12 in
engagement with contact spring H, insulated from E by block 10. The circuit
will thus be closed between the battery and gong, which latter will sound a single
signal or stroko on the bell theroof. The circuit closing wheel revolving from left
to right will soon liberate the spring point E" from engagement with the first tooth
theroof, allowing it to resume its normal position. As the wheel revolves the next
tooth or projection will operate to raise contact spring E¹, and bring it iu
engagement with contact spring H"; the circuit being closed the signal will bo
sounded once, the circuit be again broken as before, only to be reclosed by the third
and last tooth of this set. Tho gong has now sounded three separate times, but the
train is arranged to carry the wheel around in completing its half revolution
to the next set of teeth on the opposite side of the wheel. The object of this being
to bring the other set of teeth in position for immediate action on the occasion of
the next sounding of the cautionary signal. The circuit has now been closed and
broken, and the gong sounded three times, and the circuit closing wheel brought into
position for the next signal in the space of one minute, more or less, during which tho
current has been flowing through the magnets Co, C", of the circuit closer.
Automatic mechanism in connection with the stop pin wheel will break the circuit
between points 10 and plates 010. At tho expiration of this chosen moment the
magnets will be deinagnetized, the armature will cease to be attracted to their poles,
and will of its own gravity assume its normal position; the hooked end of the
escapement lever will bo received in a notch in the rubber disc, the rear arm of
said lever will be raised to engage with the vibrating hook, and the motion of the
train will be arrested. The circuit does not necessarily flow through the clectro
magnets of the circuit closer for the space of one minute, or even long enough to
allow the train to move and carry the rubber disk forward far enough to prevent
the hook from dropping back into the same notch, as the signal gong circuit may
be opened almost instantly after the train is set in motion, and the hooked end of
arm E¹ will rest upon the periphery of the rubber disk and prevent the arm d¹
from engaging with the vibrating hook d" until tho said hooked end of arm Elo
drops into the next notch in the disk. Three signals separately sounded through
in quick succession have been given, and it now becomes necessary to sound the
gong once at the moment the train leaves the station for a starting signal. This
is effected by the time signalling apparatus alone without any intervention or
action on the part of the circuit closer, further than the passing of the current
through wires attached to the standard. The stop pin wheel in its revolution from
right to left will by certain adjustments have revolved in three minutes from the
time when the circuit between points 10 and plate 010 was closed sufficiently far
forward to allow another circuit closer in same line with and forward of the circuit
closer, closing the circuit between 6 and o, to fall into the space formed by the with-
drawal of a pin from the stop pin wheel, as before described, and close the circuit
o This current will flow through wire m" to m, from thence to binding
post B, thence to binding post A", and from thence to the gong, returning by a
path indicated by D, C, A, and M. The sounding of the starting signal as will
be seen by following the paths of its current does not set the circuit closer train in
motion, as this signal consists in a single stroke on the gong bell and requires no
modification of the currents. If at any time other than indicated on the time table
it should become necessary, as for special and extraordinary trains, to sound the
signals it may be done without disturbing the adjustment of the stop pin wheel
by switching the battery currents on to wire X1 A pressure on the hand knob
10 will now close the circuit and sound the cautionary signal, and the hand
knob P similarly manipulated will close another circuit and sound the starting
signal. In the foregoing description I have detailed the construction and practical
1

page_text: operation of my circuit closer, as used in connection with my time measuring
mechanism. A system of signaling having been determined upon, and the circuit
closer having been once adapted thereto and placed in its position in the circuit, it
will need no attention save that of rewinding the motor. The time table may be
altered and the stop pin wheel adjusted to correspond therewith without altering
or disturbing the circuit closer adjustments. Particular attention was given in
designing this machine to produce an article capable of performing every desired
function and yet be one of extreme simplicity. The train and escapement are so
simple as to insure a correct action, and an incorrect signal happening under the
present system of signalling, and often the cause of serious trouble and annoyance, 1
is rendered almost an impossibility. It is evident that many slight changes in the
construction and arrangements of parts of my improved time measuring mechanism
and automatic electric circuit closer may be resorted to without departing from the
spirit of this Invention, and hence I would have it understood that I do not limit it
myself to the particular arrangement of parts shown and described, but hold myself
