Improvements in Conduits for Cable Railways, and in Grip and
Safety Mechanism and Signals therewith Employed.
We, JOHN HYDE PENDLETON of No. 601 Hamburg Avenue, Brooklyn, in the
State of New York United States of America, Civil and Mechanical Engineer,
ANDREW BRYSON Jr. of No. 18 West 21st Street in the City of New York in said
State of New York, Civil and Mechanical Engineer, and CORNELIUS TIERS of
No. 234 Fifth Avenue in said City of New York President of The Rapid Transit
Cable Company of said City and State of New York, do hereby declare the nature
of this invention to be as follows :-
Our present invention relates to improvements that are especially available in
Cable railways in which the endless travelling cable is within a trunk or conduit
below the surface of the earth or pavement.
We employ a gripping device that is suspended from the car so that it can be
disconnected instantly from the car in case à broken strand of the cable or any
enlargement of the cable should become so entangled or jammed in the grip that the
latter cannot be disconnected from the cable.
As an additional means of safety we provide for signalling from a car to the house
where the engine is located that drives the endless cable so as to notify the engineer
at the engine house to stop the cable, to run the same faster or slower or to reverse
the direction of travel of the cable as the necessity of the case may require.
The trunk or conduit and the cable supporting guide pulleys within said conduit
are specially designed for use with our improved gripping mechanism; and the
conduit is made with reference to allowing easy access to the cable supporting guide
pulleys, for oiling them or for repairs, for adjusting the opening through which
passes the connection from the car to the grip and for conveying away any water that
may pass into the conduit.
Referring to the grip-mechanism, we make use of a suitable frame supported by
the car-axles and in suitable bearings upon said frame there are shafts having hooks
that support a horizontal plate that carries the gripping mechanism; when said
shafts are turned so as to swing said hooks, the plate and all the grip mechanism
are dropped in order that the car may be stopped while the grip mechanism may be
carried along with the cable should the cable become entangled with the grip thus
Fender plates
avoiding injury to the car and the passengers carried by the same.
are provided upon the frame beneath the car to force down the grip mechanism
after it has been disconnected from the car, so that it will not strike the car axles
or other part of the car.
The shafts carrying the hooks are operated by a lever upon the platform of
the car, which lever is upon a shaft that acts, through arms, links and a three
armed lever, upon the shafts carrying the hooks. There is a hanging standard
bolted to the grip supporting plate, and this standard is made as a thin plate to
pass through the slot in the top of the conduit, and upon the lower portion of the
hanging standard within the conduit is a block carrying a wheel to run against a
rail placed at the curves in the road to resist the lateral strain of the cable as the car
travels upon said curves.
The block upon the hanging standard has jaws to receive wheels upon which is
an endless belt having grip blocks composed of layers of leather or other suitable
material secured to said belt, and these blocks are grooved to fit over the endless
cable and against these blocks the cable is pressed by a grip-shoe when the cable is
to be gripped.
There are guard plates secured to the opposite sides of the block to keep the

page_text: endless belt in position upon its wheels. The grip-shoe is at the lower end of
vertical slides connected at the top by a cross-piece and at the bottom by a
longitudinal bar which carry pick-up wheels. These wheels are conoidal and stand
at an inclination and the cable rests in the grooves of these wheels and said wheels
revolve freely to prevent friction upon the cable when the car is at rest.
The grip shoe is grooved in its upper surface to receive the cable, and the ends of
the grooves are flaring or beveled so that there are not any sharp angles to come in
contact with the cable and at the ends of the grip shoe there are hooks that rise
above the upper surface of the cable and these hooks are also rounding upon their
edges.
After the cable has been picked up as hereafter described the cable travels upon
the pick up wheels and above but not in contact with the grip shoe, but when the
slides wheels and shoe are lifted the cable is brought into contact with the endless
belt and the latter will be put into motion but the car will still remain at rest; but
when the slides, shoe and pick-up wheels are lifted higher the cable will be bent
downwardly and the grip shoe will come into contact with the under side of the
cable and the friction will be increased until finally the cable is clamped between
the grip shoe and endless belt and the motion given to the car corresponds to that of
the cable.
We prefer to make use of a toggle-movement for raising and lowering the slides
and parts carried by them, the same consisting of a crank arm upon a short shaft
that projects from a block connected to the upper cross-piece of the slides, and said
crank arm is connected to a second crank arm upon a short shaft carried by the
grip supporting plate and upon the latter shaft is a pinion gearing into a rack upon
a bar whose ends are connected to chains that pass around chain wheels upon hand
wheel shafts upon the platforms of the car so that by turning either of these shafts in
one direction or the other the rack bar is moved and the grip shoe raised or
lowered.
When the cable is to be picked up, the slides, grip shoe and pick-up wheels are
lowered and the inclined faces of the pick-up wheels come into contact with the
cable and displace it laterally and said cable slides up the, inclined surfaces of the
pick-up wheels and jumps up over and into the hooks upon the shoe.
In order to discharge the cable from the hooks of the shoe when the latter is
lowered we make use of swinging chocks at the front and rear of the slides and
upon the pivot of each chock there is a lever and upon the guard plate before
mentioned there are stationary arms. As the slides are lowered each lever comes
into contact with one of the stationary arms and the levers are swung and in swinging
they swing the chocks which force the cable out of the hooks of the grip. A spring
bolt holds each chock in position so that the cable cannot be picked up by the pick-up
wheels and pass into said hooks as the slides and chocks are lifted and just before said
slides complete their upward movement the levers come into contact with the other
stationary arms which swing the levers and withdraw the bolts from the chock and
the further movement of said levers swing the chocks to their normal position.
The brakes for the car wheels are of usual character but the brake chains pass
around chain wheels upon the same band wheel shafts that operates the grip; the
chain wheels for the grip and brake mechanism are loose upon the hand wheel shafts
and upon each of said shafts there is a sliding clutch that can be moved by a foot
lever into contact with either chain-wheel so as to operate either the grip or the brake
mechanism as may be desired.
To signal from the car to the house where the engine is located we make use of an
electric conductor or conductors that follow the line of the endless cable and the said
conductor or conductors are supported upon insulating material secured to the inside
wall of the conduit. In the electric circuit there is a battery and electro-magnet
and the latter is in the house where the engine that drives the endless cable is
located.
When two electric conductors are used, the signalling may be done upon either an
open or closed circuit by simply bringing a metallic plate upon the two conductors so

page_text: as to bridge them, which either energizes or demagnetizes the electro-magnet at the
engine house, and a bell or other signal is operated by said electro-magnet each time
that the metallic plate is brought into contact with said conductors. The code of
signals may be of any desired character; thus one bell may indicate "stop the
cable"; two bells "run the cable slower" three bells "run the cable faster" and
so on.
We prefer to use a single electric conductor and in that case one pole of the
battery is connected to the ground, and the circuit closing plate upon the car is
connected by a wire to a bearing of the car axle so that when said plate is brought
into contact with the electric conductor the current passes from the battery by the
electric conductor to the metallic plate and by said wire and metallic parts of the
car to the ground and returns to the battery by the earth, and the signal is given by
the electro-magnet ringing a bell or operating a signal device of any kind to notify
the engineer at the engine house.
If a bell is employed the electric connections may be such that the bell will ring
continuously so long as the metallic plate upon the car is kept into contact with the
electric conductor or conductors.
The electro-magnet may, besides giving the signal, be used to operate the cock
that admits steam to the engine that drives the endless cable, so that if the occasion
should arise, the attendant upon the car could stop the endless cable instantly by
bringing the metallic plate upon the car into contact with the electric conductor or
conductors.
The armature lever of the electro-magnet might act directly upon said cock to
close the same, or said armature lever might act upon a cock in a branch steam pipe
to open the same and admit steam to a cylinder containing a piston and move the
same and by its piston rod close the main steam supply cock of the engine.
The metallic plate or circuit closer is at the lower end of a rod that passes through
the slot of the conduit, and said rod may be fitted so that it can be operated from
either end platform of the car by an arrangement of rods, levers and chains, or said
metallic plate may be at the lower end of a rod that can be passed by hand down
through the slot in the top of the conduit and then turned and lifted to bring it into
contact with the electric conductor or conductors; the handle of this rod should be
insulated.
The circuit closing plate is made with a roughened or file surface so that it will
scrape off any dirt or oxide upon the electric conductor to ensure a good electrical
contact and this plate is preferably pivoted to the rod and provided with a spring
so that it may yield to inequalities or bends in the electric conductor.
When the signalling device is used upon an elevated road, the electric conductor
or conductors will be secured to one of the wooden guard rails of the structure.
A lock may be provided for securing the rod of the circuit closer, so that it can
only be used by the attendant upon the car who has the key of said lock.
We make the conduit for the endless cable of an elliptical form and of a size to
receive the grip inechanism before described, and this conduit is buried in the
ground midway between the two rails of each track; the walls of the conduit are
of boiler iron strengthened and supported at suitable distances in its length by
T-shaped angle irons.
The upper end of the conduit is partially closed by L-shaped rails extending
inwardly towards each other leaving a longitudinal slot through which passes the
hanging standard and slides of the grip mechanism before described.
The downwardly projecting flanges of said rails are riveted to the conduit, and
there are plates for supporting said rails which plates are riveted to the conduit
and rails.
The angle iron ribs of the conduit are connected to a cross bearer that extends
across the lower portion of the conduit, and said angle iron ribs, cross bearers and
parts connected with them are made use of at suitable distances along the length of
the conduit. At the outer ends of the cross-bearers there are columns having shoes
for the sleepers to rest upon, and on these sleepers are the rails for the car wheels.

page_text: The shoes are connected to the sleepers by angle irons and there are diagonal braces
extending from the upper part of each column down to the cross-bearer, the parts
being riveted together.
We employ guard plates upon the outside of the conduit to prevent the direct
contact of the paving stones and earth with the conduit and these guard plates are
suspended by studs secured to the conduit.
Stiffening angle plates are used at the upper end of each angle iron rib on the
conduit and a tension bar having a forked end is riveted to the angle iron rib and
stiffening plate; the other end of the tension bar is screw threaded and passes
through the sleeper and is provided with a nut. By adjusting the nuts of these
tension bars the slot in the L rails at the top of the conduit may be made wider or
narrower as occasion may require.
The nuts upon the tension bars come outside the sleepers and said nuts are protected
by movable metal boxes each having a recess and lifter so that the boxes can be
pried up by a lever to give access to the nuts.
The bottom of the conduit is preferably filled with cement so as to form a trough
or gutter for water to run to the sewer connection.
The cable supporting wheels in the conduit are placed at suitable distances apart
and supported in suitable bearings and each wheel is made with a flange at the
smaller portion of the conical surfaces so that the cable runs in the groove between
the flange and the larger conical portion of the wheel, and there is but little risk of
the grip or pick-up wheels coming in contact with the cable supporting wheels.
These cable supporting wheels might however each have a bearing supported by
pivoted arms so that the wheel would be moved sidewise if the grip or pick-up
wheels came into contact with said wheel.
In order to give access to the cable supporting wheels for oiling or repairs, we
make use of a transverse trunk extending from one conduit to the other and preferably
at an inclination to the middle, so that water passing into the conduits will run into
the transverse trunks and from the latter pass by pipes to a sewer or drain.
We provide a vertical entrance tube opening into each transverse trunk for giving
access to said trunk, and the top of this entrance tube is level with the sheet and
provided with a cover.
There may be wooden planking upon the outsides of the conduits, or such wooden
planking may take the place of the metal plates of the conduit, the structure otherwise
remaining the same.

Improvements in Conduits for Cable Railways, and in Grip and
Safety Mechanism and Signals therewith Employed.
We, JOHN HYDE PENDLETON of No. 601 Hamburg Avenue, Brooklyn, in the
State of New York, Civil and Mechanical Engineer, ANDREW BRYSON Jr., of
No. 18 West 21st Street, in the City and State of New York, Civil and Mechanical
Engineer, and CORNELIUS TIERS of No. 234, Fifth Avenue, in said City of New
York, President of The Rapid Transit Cable Company, of said City and State
of New York, all in the United States of America, 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 :-
Our present invention relates to improvements that are especially available in
cable railways in which the endless travelling cable is within a trunk or conduit
buried in the earth.

page_text: We employ a gripping device that is suspended from the car so that it can be
disconnected instantly from the car in case a broken strand of the cable should
become so entangled in the grip that the latter can not be disconnected from the
cable.
As an additional means of safety we provide for signalling from a car to the
house where the engine is located that drives the endless cable, so as to notify the
engineer at said engine house to stop the cable, to run the same faster or slower, or
to reverse the direction of travel of the cable as the necessity of the case may
require.
The trunk or conduit, and the cable supporting guide pulleys within said conduit
are especially designed for use with our improved gripping mechanism; and the
conduit is also made with especial reference to allowing easy access to the cable
supporting guide pulleys for oiling them or for repairs, for adjusting the opening
through which passes the connection from the car to the grip, and for conveying
away any water that may pass into the conduit.

The railway tracks a a¹ are of any desired sectional shape, preferably those
represented as adapted to lie flush or nearly so with the pavement of the street

page_text: and these railway tracks rest upon and are attached to the wooden sleepers b. The
platform A, wheels B and axles B are of ordinary character and upon the axles B¹
are bearings C supporting the longitudinal bars or frames and there are cross
frames the parts being constructed so as to receive the moving parts of the
apparatus hereafter described.
Upon the cross frame (are bearings 2 for the longitudinal shafts D upon which
are hooks 3 that support the plate F which plate supports and carries the gripping
device hereafter described so that when these hooks 3 are separated the plate can
be dropped together with all the parts of the grip in order that the car may be
stopped while the gripping devices may be carried along with the cable should the
same become entangled therewith thus avoiding damage to the car or the passengers
carried by the same.
In order to operate the hooks 3 to disconnect them from the plate F any suitable
mechanism may be employed, we have however shown the lever arms 4 as extending
above the shafts D and connected by links 5 to the three armed G upon the fulcrum 6
the third arm of which lever is connected by the link 7 to an arm 8 upon the
longitudinal shaft 9 that is beneath the platform A and acted upon by a lever G¹
whenever it becomes necessary to drop the plate F and the parts therewith connected.
Beneath the plate F is a hanging standard H that passes down into the trunk or
conduit K in which is the cable L and this hanging standard is sufficiently thin to
pass through the slot in the top of the trunk or conduit and this trunk or conduit is
to be of the character and of a size to receive the parts of the grip as hereafter
described.
Upon the lower portion of the hanging standard H is bolted or cast the block H¹
having a recess for the reception of the horizontal wheel M upon the vertical axis
and this wheel M projects at each side further than the surface of the block H' and
within the trunk or conduit K wherever curves may occur the guard rail N is
affixed as represented in Figure 1 against which this wheel M rolls to prevent the
parts being injured by a lateral strain of the cable as the car travels around the
curve, and this stationary guard rail N may be at either side of the horizontal
wheel M according to the direction of the curve in the track and in the trunk or conduit.
The block H' is formed with jaws as seen in Figure 4 for the reception of the
wheels 00' around which pass the endless belt P having grip blocks 10 upon the
surface thereof which grip blocks are preferably recessed to fit over the cable I.
This endless belt and grip blocks may be constructed in any desired manner; we
have represented the grip blocks as composed of layers or sections fastened to the
belts of leather that pass around the wheels 001. At each side of the endless belt
and grip blocks are the guard plates 12 bolted upon the opposite surfaces of the
block H. It will now be understood that the endless belt of grip blocks and the
hanging standard H always remain in a fixed position in relation to the plate F but
at each side of the hanging standard H are slideways for the reception of the vertical
slides Q. These vertical slides Q are connected at the top by the cross piece or
frame 13 and at the bottom by the longitudinal bar Q₁ the ends of which bar Q¹
extend to and receive the gudgeons or shafts 14 of the pick up wheels R. These
wheels R are conoidal, the peripheries being concaved and the wheels occupying an
inclined position as shewn in Figure 1, in order that the cable may rest in the concave
upper surface of these wheels R, and these wheels revolving freely prevent friction
upon the cable when the car is at rest.
Upon the slides Q is the grip shoe S the upper surface of which is grooved
longitudinally for the cable and the ends of the groove are made flaring or bevelled
so that there are not any sharp angles with which the cable can come into contact
and towards the ends of the grip shoe S are the hooks 15 that rise above the upper
surface of the shoe and these hooks also are rounding at their edges so that there are
no angles to come into contact with the cable.
It is now to be understood that after the cable has been picked up as hereafter
described it travels upon the wheels R and above but not in contact with the surface
of the grip shoe S and the cable will not be exposed to wear or friction but when

page_text: the slides are raised sufficiently to bring the top surface of the cable L into contact
with the grip blocks 10 on the endless belt P as illustrated in Figure 2, the endless
belt will revolve by contact of the grip blocks with the cable but the car will still
remain quiescent and as the slides Q, shoe and wheels, are still further raised the
cable will be bent downwardly and the grip shoe brought into contact with the under
side of the cable and friction applied thereto until finally the cable is clamped between
the grip shoe and the endless belt and the motion given to the car corresponds to the
speed of the cable.
In order to raise and lower the vertical slides Q and parts carried by the same any
suitable mechanism may be employed but we prefer to make use of a toggle move-
ment, the same being composed of a crank arm 23 upon a gudgeon or short shaft 22
that projects from the block 18 that is received between the lugs 19 on the cross
piece 13 of the slides Q and by making use of a key or wedge 20 passing through
the block 18 and lugs 19 the gudgeon 22 may be raised or lowered to adjust the
parts and compensate any wear. There is upon the plate F a bearing 21 for a short
shaft 17 at one end of which is a crank arm 16 united by a pin 24 to the crank arm 23
so as to form therewith a toggle joint and at the other end of the shaft 17 is a gear
wheel 26 the teeth of which mesh into teeth upon the rack bar T which bar T passes
through and is supported by the cross frame Cs, and at the ends thereof are rods 27
that pass to chains and vertical shafts with hand wheels hereafter described so that
by turning these vertical shafts and hand wheels the rack bar T can be moved in
either one direction or the other and when moved in one direction the cranks 23
and 16 acting as toggles force up the cross piece 13 and vertical slides Q raising the
bar Qgrip shoe S and wheels R to lift the cable and finally clamp the same as
before mentioned and when the rack bar T is moved in the other direction the
toggle cranks 16 and 23 move the slides Q downwardly to the desired extent for
relieving the grip, dropping the cable or picking up the cable as hereafter explained,
and we remark that the plate F is recessed as shewn in Fig. 5 so as to allow for the
movement of the crank arm 16 down to the lowest position.
Within the trunk K are the wheels U that support the cable L, these wheels U are
conical and flanged at 28 so that the cable Lin its normal position travels at the
junction of the conical surfaces of the wheels and of the flange as shewn by dotted
lines in Figure 1, these wheels U are each supported in a frame 30 with suitable
journal boxes for the shaft of the wheel, and there are diagonal links 31, 32 pivotted
at their upper ends to the frame 30 and at their lower onds they are hinged to the
blocks 33. Each of these frames 30 has two pairs of the diagonal links and one link
in each pair has a foot piece 34 that rests upon a block 35 or stop at the bottom of
the trunk or conduit so that in their normal positions the pairs of links 31, 32 occupy
the diagonal positions shewn in Figure 1, but should the diagonal surface of either
of the wheels R come into contact with either of the cable supporting wheels U
such wheel U will be moved towards one side of the trunk or conduit K, the
links 31, 32 swinging and the frame 30 moving laterally along with the wheel and as
soon as the disturbing influence ceases to act upon such wheel U the same drops back
into its normal position. It is usually intended to pick up the cable between one
wheel U and the next but should the effort be made to pick up the cable adjacent to
one of the wheels U such wheel will be displaced laterally by the inclined surface
of one of the wheels R.
When the vertical slide Q and the parts carried by the same are forced downwardly
so that the inclined faces of the wheels R come into contact with the travelling
cable L such cable L is displaced laterally and slides up the inclined surface of the
wheels near which the cable may be picked up and we find practically that it is
not necessary to lower the wheels R to the position shewn in dotted lines in Fig. 1,
because as soon as the gudgeons 14 of the wheels R pass below the cable the traction
of the cable is upon the edges of the wheels R above the axis and such wheels are
set in motion by the cable rolling up over the edges of the wheels and it jumps up
over the hooks 15 into the shoe S, for this reason, the cable can be picked up with

page_text: facility and the tension of the cable and movement cause it to pass easily into its
position in the shoe.
It will, however, be understood that if only the devices hereafter described were
made use of the cable could not be dropped because after the slides and parts
connected therewith had been lowered the cable would not be discharged from the
shoe S but would remain therein.
In order to discharge the cable from the shoe we make use of the swinging
chocks V pivotted at 37 upon the end portions of the slides where they extend
beyond the shoe S and the lower ends of these swinging chocks are adjacent to the
cable as it lies in the shoe S. The pivots 37 also form pivots for the levers 38 that
extend out over the cable and upon the guard plates 12 are stationary arms 39
and 40 and through each swinging chock V a bolt 41 passes the outer end of which
is attached to a spring 42 and there is a wedge shaped claw arm 44 projecting
downwardly and backwardly from each lever 38 the wedge shaped end of which
passes in between the spring 42 and the surface of the chock so that when the lever 38
is moved downwardly the wedge upon the end of the claw arın acts against the
spring 42 to withdraw the bolt 41 and when the lever 38 is moved upwardly the
reverse action takes place and by reference to Fig. 1 it will be seen that the lever 38
has a projection 45 upon it that comes into contact with the projection 46 upon the
chock V so that when the slides Q are moved downwardly the levers 38 come into
contact with the stationary arms 40 and the further movement causes the projections 45
to take against the projections 46 and the still further downward movement causes
the chocks V to be swung by the levers 38 and the lower ends of such chocks V act
against the cable L and throw the same over the hooks 15 and out from the shoe S
and when this takes place the wedge shaped claw arms 44 are away from the bolts 41
and the springs 42 are now free to project such bolts into holes in the vertical slides Q
so that such chocks V are held by the bolts in the inclined positions represented by
the dotted lines in Figure 1, and hence the cable is forced away by these chocks V
and cannot be picked up by the wheels R upon the upward movement of the slides Q
but during this upward movement when the parts approach the positions shewn in
Figs. 1 and 2 the levers 38 come into contact with the stationary arms 39 so that
such levers 38 are swung until the wedge shaped claws 44 pass in under the spring 42
and withdraw the bolts, and the further upward movements of the parts swing the
chocks V back to their normal positions so that the cable can be picked up by lowering
the slides and the parts connected therewith until the cable is pressed aside by the
inclined surface of the wheels R and shoe S and jumps up into the shoe as before
described.
Upon the frame C¹, C8, we place inclines (which are in the form of plates and
these run over the upper ends of the vertical slides Qafter the hooks 3 may have
been moved and the plate F dropped thereby forcing down the vertical slides Q and
the parts connected with them so that they will not come into contact with the
axles B' or the fenders or life guards upon the car.
:
It is to be understood that any suitable brakes and levers may be applied to the
wheels of the car to stop the same when the cable is disconnected and that these
brakes must be relieved from the wheels before or simultaneously with the grasping
of the cable, but we have represented in Figs. 6, 7 and 8, a device which is especially
adapted to alternate operations of the brakes and grip. In this arrangement the
brakes 0 are upon the brake bars 51 and these are connected by the rods 52 to the
lever 53 in a manner similar to the brakes cominonly made use of and from the ends
of the lever 53 the rods and chains 54 pass to the chain pulleys 55 that are loose
upon the lower ends of the shafts 56 which shafts pass vertically through the end
sill V of the platform and are provided with handles or hand wheels at the upper
ends whereby such shafts can be rotated in either one direction or the other.
Upon the shafts 56 are the chain wheels 58 around which pass the chains 59
passing to the ends of the rack bar T or to the rods 27 connected therewith and these
chains 59 also pass from one chain wheel 58 to the other or are connected by the

page_text: rod 60 so that such chains 59 can be acted upon from either end of the car platform
and so also can the brakes 50 and rods and chains 54. Both the chain wheels 58 and
chain pulleys 55 are loose upon the shafts 56 and upon each shaft 56 there is a clutch 62
sliding upon a feather on the shaft and engaging either the chain wheel 58 or the
chain pulley 55 and when in an intermediate position such clutch 62 is out of contact
with the chain wheel and pulley and we prefer to make use of the bent clutch lever W
to each clutch 62 such lever passing through a slot in the platform and having a foot
piece or head 63 by means of which the clutch can be changed and brought into
contact with either the chain pulley 55 or the chain wheel 58 and any suitable spring
pawl can be made use of to hold the lever W and clutch in either position in which
it may be placed. The lever W may be provided with a handle portion extending
above the platform so that said lever may be operated either by hand or by the foot.
It is now to be understood that at the rear end of the car platform the clutch
lever W and clutch 62 are to be set in the intermediate position so that the chain
wheel 58 and chain pulley 55 are free to turn upon the shaft 56 but at the front end
of the car the driver or conductor operates the lever W by his foot and when the
brake is to be applied he connects the clutch 62 with the chain pulley 55 and in doing
this the chain wheel 58 is disconnected so that it is not turned by the rotation of the
shaft 56 and the driver can apply the brakes to stop the car, and when the clutch
lever W and clutch 62 are moved to connect the chain wheel 58 with the shaft 56 the
driver is enabled to move the rack bar T either one way or the other way for acting
upon the grip and thereby moving such grip to pick up the cable to bring the cable
into contact with the grip blocks or the endless belt P or to grip the cable firmly
between the grip shoe S and the grip blocks 10 and the driver can liberate the cable
from the grip and stop the car or he can lower the grip shoe and wheels so as to
throw off the cable and entirely disconnect it from the car, or he can raise up the
grip shoe and parts connected therewith to throw back the swinging chocks V and then
the shoe and pick up wheels R and parts that actuate the samne can be moved
downwardly to pick up and raise the cable as before described.
It is sometimes necessary to make use of the guide wheel 64 for the chain 59 at
one end of the car platform so that the same will be in line with the rack bar Tas
seen in Figure 6.
We have shewn water reservoirs at 70 and pipes 71 communicating from the same
to the pipe or hollow portion 72 of the brake shoe to cool the same by the circulation
of the water.
As an additional means of safety for cable roads we provide for signalling from the
car to the engineer at the house where the engine is located that drives the endless
cable, so as to notify the engineer to stop the cable or to run the cable faster or
slower or to back the cable as occasion may require.
This feature of our invention is illustrated in Figs. 22, 23, 24, 25, 26, 27, 28, and
in order to more clearly show the circuit closing device and the means for operating
it, we have omitted in Figs. 22 and 23 the greater part of the gripping mechanism
before described.
2 and 3 are electric conductors that follow the line of the cable T, as seen in
Figs. 22, 23, 24 and 25, and said conductors are to be supported upon insulating
material secured to one of the side walls of the tunnel or conduit K.
There is a battery B10 and an electro-magnet m in the circuit formed by the
conductors 2 and 3 and when a closed circuit is employed as in Fig. 24 the battery is
at one end of the circuit and the electro magnet at the other end of the circuit.
When an open circuit is used as in Figs. 25 and 26, then said battery and electro-
magnet will be at the same end of the circuit; in either case the electro-magnet
is at the house where the engine k is located that gives motion to the endless cable L
in order that the bell that is rung by the action of said electro-magnet will be heard
by the engineer in charge of the engine.
To operate said electro-magnet m and ring the bell, we employ a metallic
circuit closing plate n' upon each car, which plate when brought into contact with
D

page_text: said conductors 2 and 3 at any place in the line of the road, forms a bridge plate, or
circuit closer for the current to pass from one electric conductor to the other.
When said plate n¹ is brought into contact with the electric conductors of the
closed circuit fig. 24, the current takes the route of least resistance and passes from
the battery by wire 2, bridge plate n¹ and wire 3 back to the battery and the electro-
magnet is demagnetized and its armature lever is drawn back by the spring m* and
the bell m is rung.
If our invention is employed with an open circuit as illustrated in Fig. 25, then
when the plate n¹ is brought into contact with the electric conductors 2 and 3, it
closes the circuit to the battery B10 and the current passes from said battery by wire 2
plate n¹ and wire 3 to the electro-magnet m and back to the battery and said electro-
magnet is energized and its armature lever is attracted and the bell m² rung.
If a single electric conductor is used as illustrated in Fig. 26, then one pole of the
battery B is connected with the ground and there is a wire or metallic connection
between the plate n¹ and a box of the car axle as indicated at 8 Fig. 22, so that when
the plate n' is brought into contact with the electric conductor 4 the circuit is closed
to the electro magnet m and the current from the battery passes by wire 4, plate n¹
and wire 8 to the car axle and by the metallic railway structure and ground back to
the battery.
In Figs. 24 and 26 we have shewn the circuit connections to the electro-magnet m
arranged so that the bell m² will ring continuously as long as the plate n¹ is in
contact with the electric conductor or conductors 2. 3, the current being pulsated at
the back stop of the armature as usual, and in Fig. 24 we have shewn by dotted
lines a separate battery a, electro-magnet a³ and bell a with circuit connections
arranged as shewn so that when the electro magnet m is demagnetized and its
armature lever rests against the back stop as the circuit will be closed to the
battery a* and the bell a will be rung continuously. In this latter instance the bell m²
may be dispensed with.
It is now to be understood that if the conductor or attendant upon the car desires
to signal the engineer to stop the cable, or to run the cable faster or slower, said
attendant brings the plate n¹ into contact with the electric conductor or conductors
and the electro-magnet is operated as aforesaid and the bell at the engine house is
rung a succession of peals according to the number of times the attendant brings
said plate into contact with said conductor or conductors; thus, one peal may
indicate "stop the cable," two peals": run the cable slower ; " three peals, "run the
cable faster," and so on according to the pre-concerted system adopted.
The plate n' should be made with a roughened face or file surface so that when it
is brought into contact with the electric conductor or conductors it will scrape off any
dirt or oxide that may be upon said conductor or conductors so as to ensure a good
electrical contact of said plate and the conductor or conductors.
Upon each car we provide a rod n having a plate n¹ at its lower end and this rod n
passes through the slot in the conduit K and is guided at its upper end in a tube n²
connected to the stationary part of the grip; at said upper end of the rod n there is a
pin entering a slot in the lever n which lever is pivotted at n' and it has a toothed
segment n engaging teeth upon a rack bar nº.
The rack bar ne is supported in the guides pp, and one end of said rack bar is
connected with the rod p by the rod p², chain p³ and bent lever p¹ the other end of
said rack bar is connected to the rod by the rods p and p' and bent lever p³.
A portion of the rod p' is made tubular to receive one end of the rod pe and it will
be apparent upon reference to Fig. 23 that when either rod p' or p is lifted, the
rack bar me will be moved to the right and its teeth will swing the lever n³, which
lever will lift the rod n and bring the plate n¹ into contact with the conductors 2
and 3 and when said rod p¹ or p' is lowered, the weight of the rod n and lever n³ will
cause the parts to resume their normal position.
The chain på prevents the lever p being moved when the rod p is lifted, and
the tubular portion of p' allows the rod to move in said tubular portion when

page_text: the rod p' is lifted, thereby preventing the lever p° being moved when sand roup
lifted.
25
The rods p' and p³ are each provided with handles and each rod is supported in a
tube p upon the dash board of the car so as to be easily reached by the conductor or
attendant upon the car and when either of said rods p¹ or p is lifted, the plate n¹
is brought into contact with the conductor or conductors.
The plate n' is connected by a bolt or rivet to the rod n¹ and said plate can move
slightly upon its pivot, so that said plate when brought in contact with the con-
ductors 2 and 3 can accommodate itself to any elevations or depressions in said
conductors, the movement of said plate being limited by the stops 4, 4.
The plate n' is preferably insulated from the arm n by a tube of insulating material
around the pivot pin of said plate.
If desired a spring m' may be connected to the plate n' which spring is sufficiently
wide at its ends to rest upon both conductors when the plate n' is brought into
contact with said conductors and the current will pass from one conductor to the
other by the springs as well as by the plate n' thereby ensuring a perfect electrical
contact of the short circuiting dévice with the conductors.
Instead of using aforesaid arrangement of parts the plate n' might be at the end
of a rod having a handle of insulating material as shewn in Fig. 27, which rod the
attendant passes down through the slot in the conduit K and then gives the rod a
quarter turn to bring the plate n¹ under and into contact with the electric conductor
or conductors.
When this separate rod n is used, it is preferable to employ a metallic guide v
shewn by dotted lines in fig. 23 which guide is supported by the car and said guide is
slotted so that the plate ¹ can be passed down through said slot and then through
the slot in the tube k and there is a wire 8 connected to one of the journal boxes of
the car axles and to this guide v as shewn also by dotted lines in fig. 23 so that
when the separate rod n is used with the single conductor fig. 5, there is a route
for the current to pass from the electric conductor 4 by the plate n¹, rod n, guide v²,
wire 8, car axle wheels and railway structure to the ground, whenever said plate n
is brought into contact with the electric conductor 4.
When our invention is used upon an elevated cable road, the electric conductor or
conductors are to be placed upon one of the wooden guard rails and the metal
plate n¹ may be upon a rod the same as shewn in fig. 27 so that the attendant upon
the car can bring said plate into contact with said conductor or conductors whenever
he desires to signal the engineer at the engine house.
We remark, that instead of the electro-magnet m ringing a bell it may operate a
signalling device of any desired kind.
In addition to employing the electro-magnet m for signalling, it may be used for
operating the steam cock m¹ that controls the supply of steam to the engine that
drives the endless cable as shewn in Fig. 26.
k represents the engine for giving motion to the endless cable L; the pipe for
supplying steam to the cylinder of said engine, and m¹ is a cock in the supply pipe k¹
which cock when turned in one direction allows steam to pass to the engine and when
turned in the other direction shuts off the supply of steam to said engine.
The armature of the electro-magnet m may be connected directly to the plug of said
cock m³ so that when said electro-magnet is demagnetized, a spring may draw down
said arm and turns the plug of said cock so as to shut off the supply of steam to the
engine and stop the same.
We prefer however the arrangement of devices shown in Fig. 26 for operating
said cock, in this figure 6' is a small cock in a pipe 63 passing from the steam supply
pipe to the small cylinder 6 which cylinder contains a piston and spring 6; the
piston rod 6' of said piston is connected by a link to the arm m10 which latter is
connected to the plug of the cock m³.
When the electro-magnet m is energized to stop the engine and cable, it draws
down the armature and opens the small cock 62 and allows steam to pass to the
cylinder bª which steam moves the piston of said cylinder and by the rod b', link b

page_text: and arm m¹0 turns the plug of the cock m¹ and shuts off the supply of steam to the
engine; as soon as the electro magnet m ceases to act the spring m moves' the
armature the other way and turns the cock 62 and shuts off the supply of steam to
the small cylinder 64 and opens an exhaust passage for the steam to escape from said
cylinder the spring now moves back the piston in said cylinder and by the
rod 67, link 6 and arm mo the cock m¹ is turned and steam again admitted to the
engine to put the same running.
By the arrangement shewn, the signal will be given each time said electro-magnet.
is energized, hence, if the devices operated by said electro-magnet should fail to turn
said cock and shut off the supply of steam, then the signal operated by said electro-
magnet will notify the engineer that he must stop the engine.
By combining the signalling device with the devices for operating the steam
supply cock of the engine, there is a double provision made for stopping the engine
and cable, for if the devices operated by the electro-magnet fail to turn the cock m
and shut off the supply of steam there is a certainty that such electro-magnet will
operate the signal to notify the engineer that he must stop the engine.
It is preferable to employ a lock at S for each rod p' or p said lock having a
bolt entering a notch in the rod so that a rod cannot be lifted until after the
lock has been unlocked by the conductor or attendant and the bolt withdrawn from
the rod.
Our improved trunk or conduit is represented in figs. 10 to 21 both inclusive.
The trunk or conduit K is buried in the ground and midway or nearly so between
the two rails of the track, and the general shape of this conduit is elliptical as shewn
in figs. 11, 12, 13 and 17, and made of plate or boiler iron within and supported by
the angle irons or ribs which are usually T shaped in section as represented in
Fig. 21, and it is preferable to bend the sheet metal of the trunk or conduit K so that
the inner face thereof is in line or nearly so with the face of the T head upon the
angle irons d as seen in fig. 21.
The upper end of the conduit or trunk K is partially closed by the shaped
rails e extending inwardly towards each other and leaving a longitudinal slot through
which the hanging standard H and slides pass down to the gripping mechanisin
made use of for seizing the cable L. These inward flanges c are rivetted to the
interior of the trunk or conduit plates and are preferably supported by plate c
extending down below the nearly vertical portions of the flanged rails c and rivetted
to the conduit and to the rails e as seen in Figs. 11, 12, 13 and 17.
с
The angle iron ribs d are connected to the horizontal cross bearer e that passes
across the lower portion of the trunk and it is to be understood that these angle iron
ribs d, cross bearers e and parts connected with them are made use of at suitable
distances along the trunk as represented in Figs. 10, 15 and 16, so as to properly
support the sheet metal with which the conduit is lined, and to obtain the necessary 4
strength in the structure. At the outer ends of the horizontal cross bearers e there
are columns for the sleepers 6 to rest upon, usually there will be horizontal shoes at
the top ends of these columns projecting out beneath the sleepers for such sleepers to
rest upon and to be connected by angle irons f¹ as seen in Fig. 17, and the diagonal
braces extend from the upper portions of the columns f down to the horizontal
cross bearer e the parts being securely rivetted together so as to form a very stiff
structure and in order to prevent the direct contact of the paving blocks or stones and
earth with the metallic plates forming the trunk or conduit, we employ hanging
removable fender plates or guards g represented in Figs. 12, 15 and 16. These are
hung on studs along their upper edges to the outside of the conduit and there are
also studs near the lower edges of these hanging guards to retain them in position as
seen in Figs. 15 and 16. The object of these guards is to prevent frost acting.
directly against the sides of the trunk as the guard plates 9 intervene between the
frozen ground and the trunk, and should the expansion of the earth due to the frost,
press the sides of the trunk towards each other and render the slot at the top too
narrow, the nuts 610 can be slackened sufficiently to allow the slot to close or nearly

page_text: so and one or more of these hanging fenders or guard plates can be pried off the studs
upon which they are hung and lifted out so that the slot in the top of the trunk can
be opened to the proper width upon again tightening up the nuts 610.
Adjacent to the upper end of each of the angle iron ribs d are stiffening angle
plates and the tension bars i having forks at their inner ends are rivetted to the
web of the external angle iron rib and to the stiffening plates and these tension bars
pass through the sleepers b and are provided with nuts 60 at their outer ends, the
object of this construction being to prevent the longitudinal slot between the inward
flanges e closing together by the action of the wheels of passing vehicles or by the
action of frost, and should the longitudinal slot for the hanging standard H and
slides Qbe too narrow at any part along the trunk or conduit it may be opened by a
wrench applied to the nut upon the proper tension bar i. The nuts 610 of these
tension bars coming outside the sleepers 6 are protected by movable nut boxes 1,
represented in the perspective view Fig. 20, such nut boxes being preferably of cast
iron notched at to set over the base of the nut and having a recess and lifter 12
in the top by which the nut boxes can be pried up by a crowbar or lever to give
access easily to the nut 60 that may be required to be tightened or slackened. These
nut.boxes can be driven down again to the level of the pavement as seen in Fig. 13
after the nuts have been acted upon.
The bottom of the trunk or conduit K may be open between one horizontal cross
bearer and the next so that any water passing through the longitudinal slot at the
top of the trunk may have opportunity to soak away, but we prefer to fill this space.
with cement or concrete to form a trough shaped gutter for water to run to the sewer
connection.
The supporting wheels U are to be placed at suitable distances apart for the cable L
and these wheels U are made with flanges 28 around the smaller portion of the
conical surfaces so that the cable runs in the groove between the conical portion and
the flange and this allows the supporting or pick up wheels R to travel along with
the grip and car without coming in contact with the supporting wheels U as indicated
in Figure 11, the cable being raised sufficiently above such supporting wheels by the
grip and the wheels R as indicated in Fig. 10.
The supporting wheels U are within the frame 30, that is secured upon the
lower part of the trunk or conduit K and between two sets of frames formed by the
angle iron ribs d and horizontal cross bearers e and the bearings within the frames 30
for the shafts of the supporting wheels U are represented in Figs. 18 and 19 such
bearings being composed of two parts bolted together as usual in journal boxes.
These bearings however are received into box shaped sockets in the frames 30 so that
they will remain in place by gravity when in use, but may be lifted out with the
pulley and its shaft whenever the bearings or the pulley are worn or injured. This
is a great convenience as it is only necessary to hold the cable up momentarily while
the injured pulley and journal box or bearing is taken out and another slipped into
place. These frames and bearings being at the cross conduit, allow the pulley to be
removed and another put in place with but a moments delay.
Under ordinary circumstances the supporting wheels of the cable made use of in
trunks or conduits, are difficult of success for oiling or repairs. We make use of a
transverse trunk m extending from one conduit K to the other and preferably at a
downward inclination to the middle so that any water passing into the trunks or
conduits K will run into the transverse trunks m and from the middle thereof pass
by the pipe p to a sewer or drain, and we give access to the transverse trunk m
by the entrance tube n which is provided with a movable cover o at the level of
the surface of the pavement so that by the removal of the cover o a man may pass
down into the transverse trunk m and pass in either direction to the supporting
pulley U for oiling or repairing the same and it is advantageous to provide these
transverse trunks and manholes in line with each supporting wheel, the two supporting
wheels in the trunks or conduits being opposite to each other so as to be accessible
through one entrance tube and transverse trunk.
:

plates of the trunk or conduit K, or such wooden planking may take the place of the
