Improvements in and connected with Maps and Guides attached
to Cycles and other Vehicles.
I, LADISLAUS GRUMM, of Hirschwang, Austria, Merchant, do hereby declare the
nature of this invention to be as follows:-
The present invention concerns an instrument called "locographe" applicable
to cycles and other vehicles of the same kind and intended to guide the cyclist or
driver on his journey by automatically unrolling a slip of
paper before his eyes the
country to be travelled over being shown upon this paper in the form of a map.
This instrument offers the following advantages:
It is very simple, light and cheap and enables the cyclist to know his whereabouts
at every point of his journey and consequently to avoid mistaking the bifurcations,
moreover the cyclist can, at any moment account for the distance travelled over
and consequently, for the distance remaining to be travelled over before reaching the
end of his journey or any other point.
The apparatus properly-so-called is composed of two drums independent of each
other and fixed in a box divided into two compartments by a partition and whose
cover is provided with an opening shut by a glass plate and allowing the cyclist
to follow the itinerary upon the map as he advances.
The drums are each composed of a cylinder having each one of its extremities
fixed on
a circular plate and its other end stopped by a second circular
plate movable longitudinally on the square axle of the drum, at the
same time rotating with it; moreover the fixed plate which is also wedged
upon the axle serves as a supporting point to a spiral spring through which the
axle passes and whose other end presses upon the movable plate and causes this to
rub against one of the lateral sides of to box so that the drums cannot turn of
their own accord under the action of the stretched paper or map rolled upon said
drums.
This map may be fixed with its extremities to the cylindrical surfaces of the
drums by means of glue, or it may be provided with small tongues fitting into
splits made in said drums, or may be fixed by any other means of fastening.
The map may also be made of an endless strap to be shifted upon the drums.
The axles are supported by one of the lateral sides of the box and by the par-
tition and are provided on the outside with buttons for turning the drums with the
hand in order to fix or remove the paper or map.
The axle of one drum passes through the partition and has a toothed wheel at
its end, gearing with a pinion fixed on an intermediary axle which also bears a wheel
which gears with a pinion on the axle of which a wheel is fixed, this wheel being
worked by an endless screw whose gearing with the wheel last mentioned is secured
by a spring blade held by means of a screw and which presses upon a ring fixed
by a pin on the axle of the endless screw. This endless screw and all the trans-
mission organs of the apparatus are lodged in the smallest compartment of the

page_text: box whose rear wall is provided with a slide-plate upon which a slide can move
worked by means of a screw which allows a leather strap to be tightened more or
less, this strap being fixed on the one hand to the plate and on the other hand to
the slide, and which by its tightening on the handle bar of a velocipede or any
other suitable part of a vehicle holds the apparatus in a rigid position.
The mechanism for transmitting the motion of the wheel of the vehicle to the
apparatus comprises a plate wedged on the axle of the wheel and provided on its
exterior lateral face with spiral grooves gearing with the helicoidal teeth of a
pinion wedged upon a stem penetrating, into a tube forming a sheath, and ter-
minated by the endless screw. The stem is provided with bearings preventing its
longitudinal displacement and fixed by means of clasps to the frame of the vehicle.
The working of this apparatus is very simple and takes place as follows: the map
or paper band upon which the itinerary is traced being first rolled on one drum
and having its extremity fixed to the other drum, as soon as the cyclist or driver
starts on his journey the toothed plate turns at the same time as the wheel of the
vehicle and works the pinion which through the axle and the endless screw trans-
mits its motion to the gearings which work the driving drum which thus adopts
a rotary motion whose speed is proportionate to that of the wheel.
Owing to the rotation of the driving drum the map drawn by this drum will
wind up as it leaves the driven drum and the itinerary will be exposed to the view
of the cyclist or rider with a speed corresponding to that of the vehicle; it follows
then, that the cyclist or rider will always know his whereabouts and how many
miles he has travelled; moreover the itinerary contains many useful informations
such as indicating the hills and descents, obstacles, a list of the principal hotels
and other useful informations; consequently this guide will be of great use to
cyclists and riders. For the return journey by the same route the itinerary must
be substituted by another traced inversely to the first.

Improvements in and connected with Maps and Guides attached,
to Cycles and other Vehicles.
I, LADISLAUS GRUMM, of Hirschwang, Austria, Merchant, 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;-
The present invention concerns an instrument called "locographe" applicable
to cycles and other vehicles of the same kind and intended to guide the cyclist or
driver on his journey by automatically unrolling a slip of paper before his eyes the
country to be travelled over being shown upon this paper in the form of a map.
This instrument offers the following advantages;
It is very simple, light and cheap and enables the cyclist to know his whereabouts
at every point of his journey and consequently to avoid mistaking the bifurcations,
moreover the cyclist can, at any moment account for the distance travelled over
and consequently, for the distance remaining to be travelled over before reaching
the end of his journey or any other point.
In the annexed drawing a form of construction of this apparatus and of its work-
ing mechanism is shown by way of example applied to a cycle.
Fig. 1 is an outside plan view of the apparatus.

page_text: Fig. 2 18 a longitudinal section of same.
Fig. 3 is a transverse section, and
Fig. 4 shows the apparatus arranged with its working mechanism on the machine.
Fig. 5 shows the transmission mechanism of the steering wheel in elevation and
cross section.
The apparatus properly-so-called is composed of two drums A and B independent
of each other and fixed in a box C divided into two compartments by a partition k
and whose cover is provided with an opening d shut by a glass plate and allowing
the cyclist to follow the itinerary upon the map as he advances.
The drums A and B are each composed of a cylinder b, 6' having each one of its
extremities fixed on a circular plate a, a and its other end stopped by a second
circular plate f, f' movable longitudinally on the square axle h, h at the same time
rotating with it; moreover the plate a, a' which is also wedged upon the axle h, h¹
serves as a supporting point to a spiral spring E, E through which the axle h, h¹
passes and whose other end presses upon the movable plate f, f¹ and causes this to
rub against one of the lateral sides of to box C so that the drums A and B cannot
turn of their own accord under the action of the stretched paper or map rolled
upon said drums.
This map may be fixed with its extremities to the cylindrical surfaces of the
drums by means of glue, or it may be provided with small tongues fitting into
splits made in said drums, or may be fixed by any other means of fastening.
The map may also be made of an endless strap to be shifted upon the drums.
The axles h, h¹ are supported by one of the lateral sides of the box and by the
partition and are provided on the outside with buttons i, i for turning the drums
A, B with the hand in order to fix or remove the paper or map.
The axle of one drum B passes through the partition k and has a toothed
wheel at its end, gearing with a pinion fixed on an intermediary axle which
also bears the wheel m which gears with the pinion n on the axle of which the
wheel o is fixed, this wheel being worked by an endless screw ? whose gearing
with the wheel o is secured by a spring blade T held by means of a screw 9 and
which presses upon a ring r fixed by a pin on the axle of the endless screw ?. This
endless screw and all the transmission organs of the apparatus are lodged in the
smallest compartment of the box C whose rear wall is provided with a slide-plate W
upon which a slide s can move worked by means of a screw t which allows a leather
strap to be tightened more or less, this strap being fixed on the one hand to the
plate W and on the other hand to the slide s, and which by its tightening on the
handle bar X, holds the apparatus in a rigid position.
The mechanism for transmitting the motion of the front wheel of the bicycle
to the apparatus comprises (Figs. 4 and 5) a plate Q wedged on the hub of the front
wheel and provided on its exterior lateral face with a spiral groove gearing with
the sprockets of a pinion R wedged upon a stem M, penetrating into a tube N
forming a sheath, and terminated by the screw p. By rotation of the plate Q its
spiral groove causes the sprocket pinion R to turn. The stem M is provided with
bearings Z preventing its longitudinal displacement and fixed by means of clips v, vl
to the frame of the machine. The working of this apparatus is very simple and
takes place as follows: the map or paper band upon which the itinerary is traced
being first rolled on the drum A and having its extremity fixed to the drum B, as
soon as the cyclist starts on his journey the toothed plate Q turns at the same time
as the front wheel of the machine and works the pinion R which through the
axle M and the screw p transmits its motion to the wheel O and this by means of
the gearings j, l, m, n works the drum B which thus adopts a rotary motion whose
speed is proportionate to that of the front wheel of the bicycle.
Owing to the rotation of the drum B the map drawn by this drum will wind up
as it leaves the drum A and the itinerary will be exposed to the view of the cyclist
with a speed corresponding to that of the machine; it follows then, that the cyclist
will always know his whereabouts and how many miles he has travelled; moreover
the itinerary contains many useful informations such as indicating the hills and

page_text: descents, obstacles, a list of the principal hotels and other useful informations;
consequently this guide will be of great use to the cyclist. For the return journey
by the same route the itinerary must be substituted by another traced inversely
to the first.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. An automatic guide for cyclists and drivers called "locographe" and consist-
ing in a map showing any desired portion of country, drums for actuating said
map and means for transmitting the motion of the vehicle to said drums, substan-
