Improvements in Incline Lifts, Incline Tramways, and Appliances
for Raising and Lowering Heavy Bodies.
We GEORGE NEWNES, Member of Parliament Wildcroft Putney Heath Surrey,
GEORGE CROYDON MARKS, 18, Temple Street, Birmingham in the County of
Warwickshire, Consulting Engineer, and BOB JONES, Sunnyside, Lynton, North Devon,
Contractor, do hereby declare the nature of this invention to be as follows:-
Our invention for improvements in incline lifts, incline tramways, and appliances
for raising and lowering heavy bodies, relates to the manner in which we construct
and arrange the brakes, the automatic safety appliances, the construction of the cars,
and the arrangement of the rails whereby there is greater safety obtained, and more
economical construction made possible than by the systems now in use.
In carrying our invention into effect when constructing an incline lift having a car
to run down with a rope or ropes connecting it to another car to at the same time run
up; we form our line of rails upon which the car runs of a single track at the top and
bottom. with a double track or turn out at the centre, to allow the cars to pass each other.
The weight of the rope or ropes we balance by having a tail or bottom rope
passing from the back of one car, then by means of a pulley at bottom around
same and up to the back of the other car. The Brakes we construct so that they
may be applied from each car independently, and applied direct to the rails upon
which the cars run, so as to act in a gripping or nipping manner.
The Safety Gear we also arrange so that the rails are gripped by the clips or
slippers, by means of a spring or springs, or weights being set in action upon the rope
breaking or its connection giving way.
The speed of the cars we control by a Governor worked off each car by the
motion of the axle, so arranged that any undue speed causes a weight or pressure
to be given to the slippers or clips, and thus the rails to be pressed against as
before described.
In applying our brakes we sometimes use a liquid and a cylinder and ram
worked by a screw or lever to give pressure upon a plunger or ram on the end of
each slipper against the rails; the liquid passing from one cylinder to the other by
means of an ordinary pipe. We employ the same or similar system of ram and
cylinder with pipes to be worked by springs or weights, to be operated when the
rope breaks. We also allow the same to be worked by the governor, giving pressure
to the rain by means of a rising and falling arm operating the end of a screw or
or lever to force out the liquid under pressure. We do not limit our system of
brakes to applications where they are controlled by liquids only; but use them
with equal advantage when worked by levers and weights.
The cars we by preference construct so that they can be run on and off the rails
on the main platform of our lift carriage or underframe, thereby leaving the surface
of platform free for goods of any kind, instead of being serviceable for passengers
only as at present when cars are secured to the platform or underframe direct.
We are by this system enabled to use a car upon the lift platform which we can run
off or on to the rails of the ordinary road or tramway when desired.

Improvements in Incline Lifts, Incline Tramways, and Appliances
for Raising and Lowering Heavy Bodies.
We GEORGE NEWNES, Member of Parliament, Wilderot, Putney Heath, Surrey,
GEORGE CROYDON MARKS 18 Temple Street Birmingham in the county of Warwick
Consulting Engineer, and BoB JONES Sunnyside, Lynton, North Devon, ('ontractor,
do hereby declare the nature of this invention and in what manner the same
is to bo performed, to be particularly described and ascertained in and by the following
statement:
Our invention for improvements in incline lifts, incline tramways and appliances
for raising and lowering heavy bodies, relates to the manner in which we construct
and arrange the brakes, the automatic safety appliances, the construction of the cars, and
the arrangement of the rails whereby there is greater safety obtained, and more
economical construction made possible than by the system now in use.
In carrying our invention into effect when constructing an incline lift having a
car to run down with a rope or ropes connecting it to another car to at the same
time run up; we form our line of rails upon which the car runs of a single track at
the top and bottom, with a double track or turn out at the centre to allow the ears to
pass each other. That is to say we do not require to make the tracks at the top and
bottom of a width which will allow of the cars passing each other, but we turn or
divert the rails at the central passing place as shown on Figure 2.
The weight of the rope or ropes we balance by having a tail or bottom rope passing
from the back of one car, then by means of a pulley at bottom around same and
up to the back of the other cur.
The brakes we construct so that they may be applied from each car independently
and applied direct to the rails upon which the cars run, so as to act in a gripping
or nipping manner.
The safety gear we also arrange so that the rails are gripped by the clips or
slippers, by means of a spring or springs, or weights being set in action upon the
rope breaking or its connection giving way.
The speed of the cars we control by a Governor worked off each car by the motion
of the axle, so arranged that any undue speed causes a weight or pressure to bo
given to the slippers or clips, and thus the rails to be pressed against as before
described.
In applying our brakes wo sometimes use a liquid, and a cylinder and ram worked
by a screw or lever to give pressure upon a plunger or ram on the end of each
slipper against the rails; the liquid passing from one cylinder to the other by
means of an ordinary pipe. We employ the same or similar system of ram and
cylinder with pipes to be worked by springs or weights, to be operated when the rope
breaks. We also allow the same to he worked by the governor, giving pressure to
the ram by means of a rising and falling arm operating the end of a screw or lever to
force out the liquid under pressure. Wo do not limit our system of brakes to applica-
tions where they are controlled by liquids only but use them with equal advantage
when worked by lovers and weights.
The cars wo by preference construct so that they can be run on and off the rails on
the main platform of our lift carriage or underframe, thereby leaving the surface of
platform free for goods of any kind, instead of being serviceable for passengers only as
at present whon cars are secured to the platformu or underframe direct.
We are by this system enabled to use a car upon the lift platform which we can run
off or on to the rails of the ordinary road or tramway when desired.
In order that our invention and the manner of performing the same may be properly
understood we hereunto append 5 sheets of explanatory drawings to be hereinafter
referred to and representing examples of the application of our invention.
Figure 1 is an elevation of the general arrangement of the car undercarriage and
track when in its top position on the incline railway or tramway.

page_text: A 15 the movable passenger car standing rigidly secured by movable brackets a, and
pins 6 to the platform B; is the undercarriage standing by means of wheels D, D, on
the rails E; F F are the top pulleys around which the rope passes, although we some-
times employ one pulley, or a system of pulleys having vertical guiding pulleys to lead
to the main horizontal pulley or pulleys. G is the bottom pulley to receive the
balancing rope H, H, in the ropes passing over the top pulleys and secured to the
safety anchor bar on the undercarriage. K is the balancing rope passing from
the back of one car to the other; L is the outlet valve for emptying the car to allow
of the water passing away through the wasto opening X at the bottom of the track;
M is the hand wheel for applying the brakos by means of gearing working a screw
and a system of lovers to cause the rails to be gripped or pressed against on each side;
N is the governor for actuating the same screw and nut which draws the manual brake
nipping levers 0 is the safety brake block; P is the controlling or manual brake
block R is the emergency brake block. S is the tank for containing the water. T, T,
are the outer girders of the undercarriage to which the tank S is secured; U, U, are
the emergency brake hand lever; V is the outlet valve handle.
Figure 2. is a plan of the tail track showing the turn out at the central passing
point W and an outline of the top pulleys F, F.
Figure 3 is a sectional elevation and Figure 4 a plan of the hydraulic brakes.
a, a are the hydraulic cylinders carried from a bracket attached to the side girders
of the undercarriage by means of flange plates cast to the cylinders and communicating
with them by means of the ribs or webs u 1; b is the ram or piston working in the
cylinders, and having a crosshead 61 at the outer end for receiving the slipper or brake
block;d is the gland with its projecting guiding horns I for preventing the
slipper block from turning, is the drawback water connection and wo is the outward
or pressure connection; that is to say the water or liquid entering at a draws the
slipper away from the rails, while that entering at w presses the slippers against the
rails.
C
Figure is an elevation of the Hydraulic pump for supplying liquid under pressure
to the Hydraulic brakes, a being the cylinder, 6 the plunger or piston, c the piston rod
screwed at one end and having a nut attached to or formed upon a bevel wheel d;
into which other bevel wheels ee work and transmit the pressure from the hand
wheel, or from the weight attached to the pitch chain wheel g; the piston rod is kept
from revolving by means of the key h secured to the gland bracket k; to 1 is the
outward or pressure connection, and 1 is the drawback water connection. The load
or weight hanging from the pitch chain wheel tends to force the plunger 6 down and thus
apply the brakes; and at the same time the hand wheel can be pressed by the attendant
in the same direction to give greater pressure by this system the brakes are always
moving towards the rails, so that should the attendant release the hand wheel then
the brakes would automatically be put on.
Figure 6 is a diagramatic elevation of its pipe systems for conveying liquid to
and from the pump and Hydraulic brakes, and Figure 6 a is a plan of the same.
a is the pump cylinder, c the brake blocks, e the bevel wheels working into the nut
wheel dare the hand wheels at each end of the car platform; 11 the draw-
back water pipes, and w 11 the outward or pressure pipes all communicating with the
pump a.
Figure 7 is an elevation of the rope safety brake.
Figure 8 is a plan, and Figure 9 a side elevation of the same attached to the
undercarriage beams.
Figure 10 is a sectional side elevation of the spring and its attachment to the
girders of the undercarriage.
Figure 11 is an elevation of the emergency brake and Figure 12 is a plan of the
same.
A is the anchor bar to which the ropes B B are attached; O are the springs
attached to the anchor bar and to the rocking levers D D; E E1 are the brackets
secured to the undercarriage girders and carrying the brake wedge blocks F, F 1,
F11, F111; G G 1 are the thrust brackets carrying the anchor bar which

page_text: receives the pall of the ropes after a certain adjusted tension of the springs has boen
obtained; H is a bracket supporting the springs and K is a girder of the under-
carriage to which this bracket is secured.
The action of the springs in the event of the ropes being broken is to pull the
wolge blocks in against the rails and theroby to check and arrest the motion of
the car.
1. is the connecting bar to which the lever M in connection with the camergency
handles, is attached; N N are rocking lovers acting upon wedge blocks 0, 01,
011, 0111; P, P1, are brackets secured to the undercarriage girders for carrying the
wedgo blocks. Upon the emergency handles being pulled the bar canses the
wedge blocks to be thrust against the rails and the motion of car thereby arrested.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed we declaro that what we
claim is :-
1. The application of hydraulic air screw or lover brakes for gripping the rails to a
car or frame for running on an incline railway substantially us and for the purposes
hereinbefore described and illustrated in the accompanying drawings.
2. The application to a car or frame for running on an incline railway of safety
apparatus for gripping the rails upon the rope breaking substantially as and for the
purpose hereinbefore described and illustrated in the accompanying drawings.
3. The application to a car or frame for running on an incline railway of an
emergency brake for gripping the rails substantially as and for the purpose herein-
before described and illustrated in the accompanying drawings.
4. The application to a car or frame for running on an incline railway of a
governor brake for gripping the rails substantially as and for the purpose hereinbeforo
described and illustrated in the accompanying drawings.
5. The application to the underframe or platform for running on an incline railway
of a movable passenger carriage substantially as and for the purpose hereinbefore
described and illustrated in the accompanying drawings.
