PROVISIONAL SPECIFICATION left by the said Ludwig Von Woje-
wodsky at the Office of the Commissioners of Patents, with his
Petition, on the 21st December 1875.
I, LUDWIG VON WOJEWODSKY, of St. Petersburg, in the Empire of
Russia, Gentleman, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN MEANS FOR FACILITATING THE TRANSIT OF WHEEL
CARRIAGES ON ROADS," to be as follows:-
The object of the Invention is that whilst the bearing wheels or
wheels proper of the carriage may be of any suitable size, the surface
at any one time bearing on the ground may be a part of a much larger
circle. For this purpose the wheels of the carriage are formed to run

page_text: on rails or suitably formed surfaces, formed in or applied to the inside
surfaces of larger wheels. The peripheries of these larger wheels have
applied to each of them a plate with a central circular opening formed
through it, for the passage and free play of a central shaft or axis which
may be rigidly affixed to the carriage. The end of this shaft is formed
to receive and hold firmly a pair of discs at distances apart, to admit of
the free play of the side plate to the larger wheel, and thereby give
steadiness to that wheel to keep it in a vertical direction whilst it is
capable of free and independent rotation. That portion of the shaft
between the discs is also provided with a pulley or roller, capable of
free rotation to act on the edge of the central opening in such disc in
case of need.
The outer portion of the periphery of each larger wheel or circle is
formed with a groove to act as a trough, to collect and throw off dirt
and prevent its passage into the interior thereof. The external surface
of these larger wheels or circles is also covered by an enclosing plate.
The axle of the smaller wheels is borne by springs of any suitable kind.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Ludwig Von Wojewodsky in the Great Seal Patent
Office on the 14th June 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, LUDWIG
VON WOJEWODSKY, of St. Petersburg, in the Empire of Russia,
Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first day of December, in
the year of our Lord One thousand eight hundred and seventy-five, in
the thirty-ninth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Ludwig Von Wojewodsky,
Her special license that I, the said Ludwig Von Wojewodsky, my
executors, administrators, and assigns, or such others as I, the said
Ludwig Von Wojewodsky, my executors, administrators, and assigns,
should at any time agree with, and no others, 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

page_text: Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "IMPROVEMENTS IN MEANS FOR FACILITATING THE
TRANSIT OF WHEEL CARRIAGES ON ROADS," upon the condition (amongst
others) that I, the said Ludwig Von Wojewodsky, my executors or
5 administrators, by an instrument in writing under my, or their, or
one of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was
to be 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 I, the said Ludwig Von Wojewodsky, do hereby
declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
in and by the following statement thereof, that is to say :-
The object of the Invention is that, whilst the bearing wheels or
wheels proper of the carriage may be of any suitable size, the surface at
any one time bearing on the ground may be a part of a much larger
circle. For this purpose the wheels of the carriage are formed to run
on rails or other suitable surfaces, formed in or applied to the inside
surfaces of larger wheels.
arrangement of parts according to my Invention.
By reference to these Figures it will be seen that the peripheries a of
the larger wheels have applied to each of them a plate d, with a central
circular opening d' formed through it for the passage and free play of
a central shaft or axis e, which may be rigidly affixed to the carriage k.
The end of this shaft e is formed to receive and hold firmly a pair of
discs c, c, at distances apart, to admit of the free play of the side plate d
to the larger wheel, and thereby give steadiness to that wheel to keep
it in a vertical direction whilst it is capable of free and independent
rotation. That portion of the shaft e between the discs is also provided

page_text: with a pulley or roller 2, capable of free rotation to act on the edge of
the central opening d', d', in such disc in case of need.
The outer portion of the periphery of each larger wheel or circle a
is formed with a groove to act as a trough to collect and throw off
dirt and prevent its passage into the interior thereof. The external
surface of these larger wheels or circles a is also covered by an enclosing
plate b. The internal surface of these larger wheels a is formed with
grooves a¹, or it may be other suitable surfaces to receive corresponding
outer surfaces of the peripheries f¹ of the smaller. wheels f, and the
axle g of the smaller wheels fis borne by springs h of any suitable kind. 1
Having thus described my Invention and means which I adopt in
carrying the same into effect, I would have it understood that I do not
confine myself to the precise arrangement of parts indicated so long
as the peculiar character of the Invention be retained as described.
In witness whereof, I, the said Ludwig Von Wojewodsky, have 1
hereunto set my hand and seal, this Thirty-first day of May, in
the year of our Lord One thousand eight hundred and seventy-
six.
