I CARL LEONHARD HERMAN LAMMERS of 2 Roseworth Terrace Gosforth
Newcastle County of Northumberland, Engineer & Manufacturer do hereby
declare the nature of my invention for IMPROVEMENT IN TRAMCARS, RAILWAY
CARS AND OTHER VEHICLES AND THE METHOD OF TAKING UP AND SETTING DOWN
PASSENGERS ET, to be as follows:-
My Invention relates to means of taking up and setting down passengers without
stopping Tram cars, Railway cars and other vehicles, carrying passengers on road or
rail when driven by Horses, Steam, Gas, traction rope or any other power-To
separate, keep Stationary and to draw towards the Tram car et. that part of the
Tramcar et. which I use for the purpose of taking up and setting down passengers;
to the using the rotation of the running wheels of the Tramcar et.; to
prevent the great strain on the driving power caused by the frequent stopping and
starting in the taking up and setting down passengers; to make the entering and
alighting of passengers with more safety and comfort and to prevent the delay
caused by frequently stopping Tramcars and other vehicles.
In
Hitherto Tramcars et. are stopped in the taking up and setting down passengers
causing thereby a great strain on the power employed driving Tramcars et.
employing horses, as the driving power, it is proved that the strain caused by
frequent stopping and starting again, is greater than all the other work the horse is
put to, and that this strain and over exertion conduces materially to the short
period, the horse so employed, is fit to work. The same applies to every kind of
power employed. Machinery of whatever description wears out and deteriorates
more by being checked, stopped and started, than by regular work it has to perform,
particularly so, on inclined rail or road.
By my Invention Tramcars et. are not stopped in the taking up and setting
down passengers, for the Tramcars et. continue running during the time passengers
are taken up and set down, no time is lost, and no check or interruption is caused
by the taking up and setting down passengers.

page_text: "
To this end I separate part of the Tramcar et. hereinafter designated "detachable
platform from the Tramcar et. proper. I keep the said platform separated,
stationary or draw it up towards the Tramcar et. by the rotation of the wheels of
the running Tramcars et. and means further on described. I make the outside-as
in ordinary Tramcars that, which constitutes the step and stair for ingress and
egress either either partly or wholly moveable and detachable, which when not
used for the purpose of taking up and setting down passengers, forms part of the
Tramcar et. and remains fixed and attached until in requisition for the taking up
and setting down passengers. The detachable platform, when so attached, permits
ingress and egress of passengers as in ordinary Tramcars et. I separate the said
platform from the Tramcar et, as further on described, when taking up and setting
down passengers and make the said platform the receptacle for passengers to be
taken up or set down.-I keep the same platform stationary, when taking up and
setting down passengers.-I draw the said platform towards the Tramcar et, by
means further on described, after the passengers have mounted or dismounted the
same. I use the rotation of the wheel of the running Tramcar et. as the power
wherewith I draw the said platform towards the Tramcar et.-The detachable
platform with either complete or part of the steps and stairs may form, when
attached, either the back or both the front and back of the Tramcar ct. in order to
suit the differently constructed Tramcars et. Swivel Tramcars et. will have only one
detachable platform, which is brought in gear with the running wheels-as further
on described either at the front or back of the Tramcar et. On what are termed
outside Tramcars, the detachable platform, with the steps and stairs or part, join
and form a continuation of the steps and stairs of the Tramcar et., one half more or
less on the Tramcar et. the other on the said platform. I may use a board or cut
away part of the said platform to remain fixed, for allowing the conductor to stand
on, when the said platform is separated.-The said platform is mounted on four
wheels more or less-running on rail or road the same as the Tramcar et. To the
detachable platform is fastened in the center or if in two places coequal distances
from the center and facing the Tramcar et., a rope or two ropes with an angular
tube or other piece of metal rod further on described. The rope or ropes may be of
hemp or any other kind, and coil and uncoil on & drum or drums. The said drum
or drums are fixed on a spindle or axle, that extends from left to right of the wheels
of the Tramcar et., parallel with the axle of the wheels of the Tramcar et., and
pivoted in bushes on the end of a lever bar, extending underneath the floor of the
Car. The said axle with drum or drums has on each end a spur wheel.
A corresponding spur wheel is on the wheels of the Traincar et; which when
brought into gear by means further on described, revolves together by the running
of the Tramcar et., but which, when out of gear leaves the axle and drum
stationary, while the Tramcar et. keeps running. The spurwheel on the axle of
the drum and the spur wheel of the wheels of the Tramcar et. are brought in and
out of gear, by the lever bar, before named, in order that the drum or drums may
remain at rest or coil and uncoil the rope et. before named.-The lever bar has an
extended handle, conveniently placed on the Tramcar for the use of the driver or
conductor. If within reach of the first, the latter may be dispensed with or may
remain on the platform to assist passengers in mounting and dismounting.-One
end of the rope or ropes is fastened as before described to the detachable platform,
and the other end to the drum or drums, always in a line, so as to meet end to end,-
When the rope or ropes are coiled round the drum or drums to its full length by
the running of the Tramcar et., the detachable platform, becomes attached and
locked to the Tramcar ct., having by the impetus in drawing up to the same, fallen
into a click, catch or pawl, at the same time presses against the lever bar and
automaticaly disconnects the gearing of the drum and spur wheels, from the spur
wheels and wheels of the running Tramcar et.-When said platform is attached
and locked the drums and ropes aro at rest while the Tramcar et keeps running.-
A second handle connected by leverage to the click, catch or pawl before named,
unlocks the detachable platform, which until unlocked, runs with the Tramcar et.,

page_text: remains now stationary on the rails or road by its own weight, or assisted by a
grapple set in action by means further on described.-When so stationary the end
of the rope or ropes fastened to the said platform, the rope or ropes uncoil off the
drum or drums, while being out of gear-to any length or distance required for
the mounting or dismounting of passengers. The length of the rope or ropes
may be twenty feet, more or less, but the uncoiling can be stopped at any time by
gearing the drum or drums and spurwheels with the spurwheel of the wheels of
the running Tramcar et.-An angular tube or other piece of metal rod, into which
I fasten one end of the rope or ropes, hangs from its center, on a pin in the detachable
platform. The said tube et. has on the end of one of its arins a grapple, anchor or
projected prongs, which catches the ground when the said rope or ropes are slack-
the detachable platform is then stationary-but is lifted off the ground and sets
free the said platform directly the said rope or ropes are in traction and coiled on
the drum or drums by the running Tramcar et. The before named grapple et is
kept off the ground by the traction and strain on the rope or ropes in the drawing
up of the said platform towards the Tramcar et.-When so drawn up and locked,
a projected bolt or knob comes in contact with the upper arm of the before named.
tube et. and secures and keeps the grapple off the ground, when released from the
strain and traction of the rope, until the said platform is again unlocked.-A spring
of less power than the traction and strain on the rope or ropes, assists in pressing
the grapple et. before named towards the ground.
I may also fix and arrange the gearing, handle, levers for attaching, locking and
detaching as before described on the detachable platform, for the purpose of my
Invention in taking up and setting down passengers without stopping Tramcars et.-
I do this by gearing the axle, having the drum or drums and spur wheels with a
spurwheel of the runnings wheels of the detachable platform in a permanent way,
the bush or bushes in which the axle of the drums run, memains the same distance
from the axle of the wheels of the said platform whether the said platform is
stationary for the taking up or setting down passengers or whether drawing up or
running with the Tramcar et. I fasten one end of the rope or ropes to the
Tramcar et and the other end on the drum or drums on which I coil and uncoil the
rope or ropes, and bring the drums in or out of action by sliding the same on
the axle. A boss fixed on the axle on which the drum or drums run freely, has,
facing the end of the drum or drums rotched like teeth or other gripping and
engages corresponding teeth et. in the drums. A spiral spring separates, the drum
or drums from the boss, until required for coiling the rope or ropes, so that when
the drum or drums are gripped, the said drum or drums run and revolve with the
boss before named, but when held back by the spiral spring just named, the drum
or drums run freely on the axle and do not revolve with the boss and the wheels of
the detachable platform, but are at rest. Conveniently placed on the detachable
platform is a handel attached to a lever having two small levers on the end, where
a cylinder like tube moving freely on the axle of the drum or drums and sets the
toothed boss and toothed drum in grip or releases them thereby bringing the rope
or ropes out of action.-The rope and ropes are released from traction, directly the
drum or drums and the boss before named, are disengaged by the lever just named
coming in contact with the projected bolt in the impetus of the drawing up
platform before described.
I may sometimes dispense with the spur wheel & axle of the drum and run the
rotched drum or drums direct on the axle of the wheels of the Tramcar et. and
detachable platform, by gripping the rotched drum or drums direct with the rotched
boss of the wheels, in the manner before described. I may also use a rod or rods
in separating, keeping stationary, or in drawing up the detachable platform for the
purpose of my Invention in taking up and setting down passengers without
stopping Tramcars et.-I do this with a flat or any shaped rod or rods, sliding in
guides underneath the floor of the Tramcar et.-One end of the rod or rods, is
fastened to the detachable platform. The said rod or rods have teeth, which gear

page_text: with a spur wheel. This spur wheel runs freely on the boss of the wheels of the
Tramcar et. on which it has side play, and a spiral spring separates it from
the grip of the Tramcar wheels, when out of action, but when caught by the
prongs of the Tramcar wheels, revolve together and engages the corresponding
teeth of the rods, thereby drawing the detachable platform towards the Tramcar et.
A lever and handle conveniently placed on the said platform, presses and keeps the
spur wheels in grip, or relieves the same assisted by a spiral spring, thereby
bringing the rods in or out of gear. The impetus of the drawing up platform
towards the Tramcar and the contact thereby, causes the lever to disengage the
spur wheel and keeps the same as well as the rods at rest, when the said platform
is locked and attached.-I may make these rods in joints, bending one way only
for the purpose of using longer rods than straight and rigid rods would permit
placing underneath Tranicars et.
I may use any of the arrangements herein before described either separate or in
combination or any other arrangement for the purpose of my Invention in taking
up and setting down passengers without stopping Tramcars Railway cars and any
other vehicles.

page_text: I CARL LEONHARD HERMAN LAMMERS Engineer and Manufacturer of No. 2
Roseworth Terrace Gosforth Newcastle on Tyne Northumberland do hereby declare
the nature of my invention for IMPROVEMENT IN TRAM CARS RAILWAY CARS AND
OTHER VEHICLES AND THE METHOD OF TAKING UP AND SETTING DOWN PASSENGERS
IN THE SAME, WHILE RUNNING ON RAIL OR ROAD AND DRIVEN BY HORSES, STEAM
GAS, TRACTION ROPE OR ANY OTHER POWER AND THE MANUFACTURE THEREOF,
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
My Invention relates to means of taking up and setting down passengers
without stopping Tram cars Railway cars and other vehicles carrying passengers
when driven by Horses, Steam, Electricity, Gas, traction rope or any other power.
To separate, keep stationary and to draw that part of the Tram-car ct., which I
use for the taking up and setting down of passengers, using the rotation of the
wheels of the running Tram-car et. for that purpose. To prevent the great strain
on the driving power caused by frequent stopping and starting in the taking and
setting down of passengers. To make the entering and alighting of passengers
with more safety & comfort, to prevent the delay caused by frequent stopping of
the Tram-car et. and to using the rotation of the running wheels of the Tram-car et.
in the manner further on described.
Hitherto Tram-cars et. are stopped when taking up and setting down passengers,
causing thereby great strain on the power employed for driving Tram-cars et.,-In
employing horses, as the driving power of Tram-cars et. it is proved, that, the
strain caused by frequent stopping and starting again, is greater than all the other
work the horse is put to, and that this straining and over exertion conduces
materially to the short period the horses so employed are fit to work.-The same
applies to every other power employed in driving Tram-cars et. Machinery of
whatever description wears out and deteriorates more by being checked, stopped
and restarted than by the regular work it has to perform, particularly so on inclined
roads or rails.
By my Invention Tram-cars et. are not stopped in the taking up and setting
down passengers, for the Tram-cars et. continue running during the time passengers
are taken up or set down, no time is lost, and no check and interruption is caused
to the driving power by the taking up and setting down of passengers.-To this
end I separate part of the Tramcar et.-hereinafter designated detachable platform-
from the running Tram-car et. I keep the said platform attached, separated and
stationary, or I draw it towards the running Tram-car et. by the rotation of the
running wheels of the Tram-car et., and means further on described.
I make the outside of the Tram-car et, forming the step or stairs for ingress and
egress of passengers as found in ordinary Tram-cars et., either partly or wholly
moveable and detachable, which when not used, for the purpose of taking up and
setting down passengers, forms part of the Tram-car et. and remains fixed and
attached until in requisition for the taking up and setting down of passengers.-
The detachable platform when attached permits ingress and egress for passengers,
as in ordinary Tram-cars et. I separate the said platform from the Tram-car et.,
as further on described-when taking up and setting down passengers, and make
the said platform the receptacle for passengers to be taken up and set down.-
I keep the said platform stationary when taking up or setting down passengers.-
I draw the said platform towards the Tramcar et by means further on described,

page_text: after the passengers have mounted or dismounted the said platform.-I use the
rotation of the wheels of the running Tramcar &c. as the means or power,
wherewith I draw the said platform towards the Tramcar et.-The detachable
platform, with either a complete or part of the steps and stairs, may, when attached
form, either the back or both the back and front of the Tramcar et., in order to
suit differently constructed Tramcars et. On what are termed outside cars the
detachable platform with the steps and stairs or part of the same, joins and forms a
continuation of the steps and stairs of the Tramcar et., one half more or less, on the
Tramcar, the other half more or less on the detachable platform. I may use a
board or cut away part of the said platform, to remain fixed to the Tramcar, to
give standing room to the conductor when the detachable platform separates from
the Car I may also leave the steps and stairs fixed as at present and have a
detachable receptacle or platform attached thereto in the manner descrived before.-
The said platform mounted on four wheels more or less held in a frame which
turns on a center block between the axles or on the middle of one axle running on
rails or road the same as the Tramcar et. To the said platform, is fastened in the
centre, or if two ropes, coequal distances from the centre, and facing the Tramcar et.
a rope or ropes with a grapnel further on described. The ropes may be of hemp,
wire or any kind, or may be a chain or chains, and coil or uncoil on a drum or
drums. The said drums are fixed on a spindle or axle that extends from right to
left of the Tramcar wheels, parrellel with the axle of the Tramcar wheels; and
pivoted in bushes at the end of a lever bar, which extends underneath the floor of
the Tram-car et.-The said spindle or axle has on each a spurwheel, actuating a
corresponding spurwheel on the running wheels of the Tramcar et., which when
brought into gear, by means further on described-revolve together, but when out
of gear, leave the spindle or axle and drums stationary and at rest, while the Tram
car et. keeps moving-The spurwheels on the spindle or axle and drums and the
spurwheels on the running wheels of the Tram-car et., are brought in and out of
gear, by the lever bar before named, in order that the drums inay remain at rest,
or to coil and uncoil the rope before named.-The said lever bar has an extended
handle, conveniently placed on the Tram-car et., for use of the driver or conductor.
If within reach of the first, the latter may be dispensed with, or may remain on
the detachable platform, to assist passenger in mounting or dismounting. One end
of the rope or ropes fastened as before described to the detachable platform, the
other end to the drums, always in a line, so as to meet end to end when coiled on
the drums. To equalize the strain on the ropes on curved roads, I have an
additional bar pivoted in the centre, fastening the ropes on the ends of the said
bar. When the ropes are coiled round the drums to the full length, by the rotation
of the wheels of the running Tramcar et., the detachable platform becomes
attached and locked to the Tram-car et. having by the impetus in drawing up the
same, fallen into a click or catch, at the same time pressing against the lever bar
before named and automatically disconnects the gearing of the drums spurwheels,
from the spurwheels of the running Tram car et.-When the said platform is
attached and locked, the ropes, drums and drum spurwheels are at rest, while the
spurwheels of the running wheels of the Tram-car et. keep revolving.
The before named lever bar, by its extended arm and handle, sets free and puts
the spurwheels into gear, directly the detachable platform separates from the
running Tram-car et.-A second handled (lever) connected to the click or catch
before named unlocks the detachable platform, which until unlocked, runs with the
Tram car et. When so unlocked, the said remains stationary by its own weight,
assisted by a grapnel set in action as further on described. When stationary the
end of the ropes fasten to the said platform, the ropes uncoil off the drums-the
spurwheels still out of gear-to any length or distance required, to keep the said
platform stationary, for the mounting or dismounting of passengers.
The length of the uncoiling of the ropes may be twenty feet, more or less, but
the uncoiling can be stopped at any time, by releasing the before named lever bar,
on which the said platform will be drawn towards the running Tramcar et. as

page_text: before described. An angulated arm into which I fasten the end of the ropes,
hangs on a pin, fixed in the said platform, this angulated arm has, a grapnel anchor
or projected prongs, which catch the ground when the ropes are slack.-—tho
detachable platform is then stationary-but is lifted off the ground and sets free
the said platform, directly the ropes are in traction and coiling on the drums. The
grapnel is kept off the ground, by the strain on the ropes in drawing the said
platform towards the running Tramcar et. When so drawn and locked, as before
described, a projected knob comes in contact with the upper arm of the before
named grapnel, securing and keeping it off the ground, when released from strain
of the ropes until the said platform is again unlocked. I may also fit or fix, and
work the handled lever bar, drums, spurwheels et. for separating, drawing up,
attaching and unlocking the detachable platform, in the manner described on or
from the said platform, for the purpose of my Invention in taking up and setting
down passengers. In such the end of the ropes are fastened to the Tramcar et.,
and the coiling is effected, by the propulsion of the running wheels of the said
platform. In swivel Tram-cars, the detachable platform remains locked to the car,
while being turned round, an extra lowerable swivel wheel or wheels, raise the
said platform to facilitate its turning round.-I may however entirely dispense with
the spurwheels axle holding the drums, and slide and revolve the drums direct on
the axle of the running wheels of the Tram-car, or on the axle of the running wheels
of the detachable platform, with a gripping on the drums and running wheels, For
this purpose I attach on the inside of the running wheel of the Car or platform, a
boss, having on the inside facing the drums, rotched like teeth, projected pins, or other
gripping engaging corresponding teeth indentions or projecting pins on the drums.-
A spiral spring separates the said drums from the boss, until required for coiling the
ropes. The said drums are actuated, by a lever further on described by which,
the drums are made to slide and grip the corresponding teeth pins or projections
of the running wheels, that when the drums are gripped, they revolve with the
running wheels of the said platform or car, but when held back by the spiral
spring before named, the said drums run freely on the axle and do not revolve
with the running wheels, leaving the drums and ropes at rest.-The drums are at
rest only, when the detachable platform is locked or stationary.-Conveniently
placed, and (pinned) on the Car or platform, is a handled lever, having a roller
on the end, which roller, actuates a shear like lever, this shearlike lever, has on
each end, a cylinder or hollow boss, moving freely over the axle, and slides the
Drums when not held back by the spiral spring-into the grip of the running
wheels, and then revolve together, until released, by the levers just named.
ropes coil on the drums for the drawing up, or uncoil, on separating of the
detachable platform and car as before described. The ropes are released from
traction or strain, directly, the said drums are disengaged or set free, by the
impetus of the drawing up platform and contact with a projected pin or knob,
against the several levers before described. A handled lever click or catch lockes
the platform in the manner before described. Sometimes I put an independent
brake to keep the platform stationary as required.-Sometimes I attach to Tram-
car et as at present made without removing the steps or stairs an additional
receptacle or platform for the purpose of taking up and setting down passengers,
in the manner herein before described. I may also use a rod or rods, in separating,
keeping stationary or in drawing up the detachable platform, for the purpose of
my invention in taking up and setting down passengers without stopping Tram-
cars et. I do this with a flat or other shaped rods, sliding in guides underneath
the floor of the car, one end of the rods being fastened to the said platform.-The
said rods are toothed on one side, forming rack rods, and gear the upper or lower
teeth of the spurwheels. These spurwheels run freely on the boss or bush of the
running wheels, on which they have side play and have, facing the running wheels
projected pins or other grippings, by which the spur wheels grip the running
wheels. A handled lever conveniently placed on the said platform actuates and
keeps the spurwheels in grip-of the running wheels, causing the rack rods-on end
The

page_text: fast to the said platform-to draw the same towards the car,-when released by the
lever just named, the spurwheels are separated from the running wheels by a spiral
spring, putting the spurwheels and rack rods out of action. The spurwheel is of
a thickness, that it remains always in gear with the rack rod, the side play it has,
before named is only to the extent of clearing the projected prong, pins or gripping.
By the impetus of the drawing up of the platform towards the car, and contact
thereby caused, as before described the lever disengages the spurwheels from the
grip of the running wheels. A lock and brake as before described is also provided.
For the purpose of prolonging the rack rods, I joint them, bending inwardly storing
the bended rack rods underneath the top end floor of the car et.
I attach and apply to all existing Tram-cars et. a detachable platform or part
thereof, or any other receptacle, most suitable for the purpose of my Invention
hereinbefore described.
]
Where a number of carriages run together, as in railway trains, I attach,
separate, lock, or keep stationary in the manner before described the last carriage 1
in preference to a detachable platform, for the purpose of my Invention in taking
up and setting down passengers without stopping train at intermediate stations.
I use separately or combined, the means herein before described, for the purpose
of my Invention in taking up and setting down passengers without stopping Tram-
cars Railway carriages or other vehicles carrying passengers, utilising the rotation 2
and propulsion of the wheels of the running Tramcar et. as hereinbefore described.―
In order that my said Invention may most fully be understood and readily carried
into effect I will proceed to describe the Drawings hereunto annexed :-

the detachable platform or any part of a Tramcar, railway carriage or other vehicle,
or part of a train, while, and during the Tramcar carriage or other vehicle or
railway train, continues running, for the purpose of taking up and setting down
passengers as substantially herein before set forth and described.
Secondly, to ultising and using the rotation of the running wheels of Tramcars,
railway carriages, or other vehicles in the mauner and for the purpose herein before
described and
Thirdly, The adaption and application of the detachable platform, or such other
additional receptacle, as may be suitable to all existing Tram car and other vehicles
for the purpose herein substantially set forth and described.
