PROVISIONAL SPECIFICATION left by the said Gustav Kessel and
Gustav Seydeler at the Office of the Commissioners of Patents, with
their Petition, on the 12th January 1874.
We, GUSTAV KESSEL and GUSTAV SEYDELER, of Berlin, Prussia,
Manufacturers, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN APPARATUS FOR MEASURING THE DISTANCES RUN OVER BY
WHEELED VEHICLES," to be as follows:-
This Invention relates to apparatus for measuring and registering the
distance passed over by wheeled carriages by means of a counter which
registers and, when so desired, records on paper the number of
revolutions made in either direction by one of the wheels of the vehicle.
to which the apparatus is applied. For this purpose the wheel, or the
axle when the wheel is fixed thereto, has on it a projection which at

page_text: at the return of the nut and pencil causes the ring to turn one tooth
round and thus to turn the paper on the cylinder so as to present a
fresh portion of its surface for the succeeding line to be marked by
the pencil.
The cylinder need not necessarily be connected to the gearing of the
recording instrument but may remain stationary, in which case the
pencil will mark a straight line on the paper during the journey of the
vehicle, being caused by the action of the spring to return along the
same line when the recording instrument is thrown out of gear.. In this
case also the cylinder would be moved round a short distance, as before
described, by the pawl and ratchet wheel acted on by the pencil reach-
ing the extreme of its back stroke, so that for a fresh journey another
line would be drawn by it on a fresh portion of the paper.
The spring gearing may have attached to it a counter, which as well
as the line on the paper, will indicate the length of the journey, and the
indices of which will be restored to the zero position by the action of
the spring, the nut on the screw serving as a stop at the end of its
back motion to prevent the indices from being turned back beyond
zero point.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Gustav Kessel and Gustav Seydeler in the Great
Seal Patent Office on the 11th July 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GUSTAV
KESSEL and Gustav SEYDELER, of Berlin, Prussia, Manufacturers, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of January, in the year
of our Lord One thousand cight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Gustav Kessel and Gustav Seydeler,
Her special license that we, the said Gustav Kessel and Gustav
Seydeler, our executors, administrators, and assigns, or such others as
we, the said Gustav Kessel and Gustav Seydeler, our executors, admini-
strators, and assigns, should at any time agree with and no others,

page_text: from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN APPARATUS
FOR MEASURING THE DISTANCES RUN OVER BY WHEELED VEHICLES," upon the
condition (amongst others) that we, the said Gustav Kessel and
Gustav Seydeler, our executors or administrators, by an instrument in
writing under our or their hands and seals, or under the hand and seal
of one of us or them, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be 1
performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date..
of the said Letters Patent.
NOW KNOW YE, that we, the said Gustav Kessel and Gustav Seydeler,
do hereby declare the nature of the said Invention, and in what manner 1
the same is to be performed, to be particularly described and ascertained
in and by the following statement thereof, reference being had to the
accompanying Sheet of Drawings, and to the figures and letters marked
thereon, that is to say :-
This Invention relates to apparatus for measuring and registering the 2
distance passed over by wheeled carriages by means of a counter which
registers, and when so desired records on paper the number of
revolutions made in either direction by one of the wheels of the vehicle
to which the apparatus is applied. For this purpose the wheel, or the
axle when the wheel is fixed thereto, has on it a projection which at 2
each revolution bears against and pushes a sliding rod. On the end of
this rod is a disc bearing on an elastic bellows which may be a
caoutchouc ball containing air. This bellows or ball is connected by a
small pipe with another bellows or ball of like kind placed in any con-
venient part of the vehicle, with a disc on the end of another sliding 3
rod bearing upon it. At every revolution of the wheel, the first bellows
or ball being collapsed, air passes from it to the second bellows or ball
which it distends, and thus the second sliding rod is caused to make
strokes corresponding to those of the first sliding rod, that is to say, a
. stroke for every revolution of the wheel. The sliding rod thus caused 3
to reciprocate carries a pawl which engages with the teeth of a ratchet.
wheel geared to other wheels having indices, so as to form a counter of

page_text: ordinary construction, whereby the number of revolutions of the wheel
is registered.
When it is desired to record by marking on paper the distance run by
the vehicle in a given journey, as for example, when the vehicle is hired
to ascertain how far it has travelled, a recording instrument is connected
to the counter in the following manner:-A train of wheels is connected
'to a volute spring like the spring of a watch, and also to a cylinder
covered with paper, and to a screw, and this train can either be thrown
into or out of gear with the counter above mentioned by means of a
handle within reach of the driver. When it is put in gear therewith, as
for example, when passengers begin their journey, the volute spring
is wound up by the action of the counter, and at the same time the
paper cylinder and the screw are turned. On the screw there is a
guided nut which carries a pencil, and this pencil, as the nut is
advanced by the rotation of the screw while the paper cylinder revolves,
traces on the paper a line of helical form extending along the paper a
distance proportioned to the number of revolutions of the wheel, that is

instrument is thrown out of gear, as for example, when the passengers
leave the vehicle, the volute spring unwinding itself causes the paper

record. In order however, that the line traced on

the paper cylinder, such ratchet ring serving to secure the paper thereon.
The pawl thus moved at the return of the nut and pencil, causes the
ring to turn one tooth round and thus to turn the paper on the cylinder
so as to present a fresh portion of its surface for the succeeding line to
be marked by the pencil.

this case also the cylinder would be moved round a short distance, as

DESCRIPTION OF THE DRAWINGS.
Fig. I., represents part of a transverse section of a vehicle to which
the measuring apparatus is applied, B being the body of the vehicle,
and W one of the running wheels. On the axle, when it revolves with
the wheels, or on the nave of either wheel is fixed the cam projection d,
which at each revolution of the wheel pushes the rod e and disc c, fixed
thereon, so as to compress the elastic ball a contained in the case b. A
pipe from this ball is led to any convenient part of the vehicle where is
situated the counting and registering apparatus, shewn in Fig. II. In
this apparatus there is the elastic ball a' connected by the pipe to the
ball a, formerly mentioned and shewn in Fig. I., so that when the latter
is compressed the pressure transmitted through the communicating pipe
causes the former to be dilated, pushing up the disc c¹ and rod e¹. A
pawl g on the rod e¹ engaging with the teeth of a wheel h is thus caused
at each revolution of the running wheel to turn the wheel h a tooth,
and the wheel h being geared with other wheels h¹ and h³ provided with
indices outside the casing f of the apparatus these indices will shew the
number of revolutions of the running wheel and thus indicate the
distance run.
The indicating gear is connected to the recording apparatus through
the bevil gearing m, n, o, of which the intermediate wheel n can be
withdrawn out of gear by means of the sliding handle p, the axis of
the wheel n being swivelled thereto and fitted to slide in the bearing n¹.
The wheel o works the screwed spindles which is connected by
gearing k, k³, k³, to the axis of the volute spring ", on which axis is the
paper cylinder t. The axes of the wheels k, k³, k³, and of the spring r
may have indices outside the casing f, as shewn. On the screw s is
fitted the nut u which has a sten y guided in the guide w and
terminating in a pencil or tracing point which bears on the surface of

page_text: the roller t. On this stem is also the inclined projection i, which
when the nut returns to the extremity of its stroke raises the cor-
responding incline on the pawl rod which turns the toothed ring t¹
one tooth so as to shift the paper for the reception of a fresh trace.
When the roller t is connected, as shewn in Fig. II., with the axis of
the spring r, the pencil will obviously trace a helical line on the paper,
the latter revolving while the former advances. The roller t, however,
may be made with its axis separated from that of the spring r, in which
case, the roller remaining at rest while the pencil advances, the latter
will trace a straight line.
Having thus described the nature of our Invention and in what
manner the same is to be performed, we claim,-
First. The use for communicating movement from a running wheel of
a vehicle to a distance registering apparatus placed in any part of the
vehicle, of two elastic balls communicating by a pipe and containing
air or other fluid, so that the collapsing of the one at each revolution of
the wheel causes the other to distend and work a pawl acting on the
registering gear, substantially as herein described.
Second. The combination with apparatus for registering by a trace on
paper the distance run by a vehicle, of a spring, whereby when the
registering apparatus is thrown out of gear the tracer is moved back to
its initial position ready to make a fresh trace, substantially as herein
described:
Third. In registering apparatus, such as is referred to above, the use
of an inclined projection on the tracing stem in combination with a
pawl stem and toothed ring, for the purpose of shifting at the end of
the return stroke of the trace the surface on which a fresh trace is to be.
effected, substantially as herein described.
In witness whereof, we, the said Gustav Kessel and Gustav
Seydeler, have hereunto set my hand and seal, this Ninth day
of July, in the year of our Lord One thousand eight hundred and
GUSTAV KESSEL.
