IMPROVE- MENTS IN WHEELED CARRIAGES
Year: 1866

page_text: LETTERS PATENT to Charles Bräutigam, of the City of Saint Petersburg,
in the Empire of Russia, Coach Builder, for the Invention of "IMPROVE-
MENTS IN WHEELED CARRIAGES."
Sealed the 7th September 1866, and dated the 1st June 1866.
PROVISIONAL SPECIFICATION left by the said Charles Bräutigam at
the Office of the Commissioners of Patents, with his Petition, on the
1st June 1866.
I, CHARLES BRAUTIGAM, of the City of Saint Petersburg, in the Empire of
Russia, Coach Builder, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN WHEELED CARRIAGES," to be as follows:-
My improvements relate to the connection of the bodies of common road
carriages with the axles carrying the fore wheels, and consist in dispensing
with the perch bolt and wheel plate, upon which in carriages of the ordinary
construction the under carriage turns, and in substituting therefor two
horizontal locking wheels or rings fitted one within the other. The inner ring
is affixed to the body of the carriage, and the outer ring is affixed to the under
carriage and turns upon the inner ring, which has upon its periphery annular
projections, which engage with corresponding depressions formed in the inner
side of the said outer ring, and thereby prevent the separation of the two
rings. The outer ring is made in two or more segments, which are connected
by screw bolts passing through lugs formed on the said segments, washers
being interposed between the said lugs. This arrangement admits of the
outer ring being fitted upon the inner ring, and screwed up from time to
time to compensate for wear, the washers above referred to being in that case
removed and replaced by thinner ones. A hole is formed in the outer ring

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
BRÄUTIGAM, of the City of Saint Petersburg, in the Empire of Russia, Coach
Builder, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of June, in the year of our Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Charles Bräutigam, Her special licence that I, the said Charles
Bräutigam, my executors, administrators, and assigns, or such others as I, the
said Charles Bräutigam, 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 Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN WHEELED CARBIAGES," upon the condition (amongst others) :
that I, the said Charles Bräutigam, my executors or 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 Charles Bräutigam, do hereby declare the
:nature of the said Invention, and in what manner the same is to be per-
forined, to be particularly described and ascertained in and by the following
statement thereof, that is to say :-
My Invention consists of the improvoments in wheeled carriages berein-after
described and illustrated in the accompanying Drawing.
My said improvements relate to the connection of the bodies of common
road carriages with the axles carrying the fore wheels, and consist in dis-
pening with the perch and wheel plate, upon which in carriages of the ordinary
construction the under carriage turns, and in substituting therefor two hori-
zontal locking wheels or rings fitted one within the other. These locking

page_text: wheels or rings and parts connected therewith are represented in plan in
Figure 1 and transverse section in Figure 2 of the accompanying Drawing,
where a is the inner wheel or ring, and b the outer wheel or ring. The inner
ring a is affixed to the body of the carriage at the parts marked c in Figure 1,
and the outer ring 6 is affixed to the springs by two arms d, d, and turns upon
the inner ring in the manner best seen in the section Figure 2. The said
ring a has upon its periphery depressions corresponding with similar ones on
the inner side of the outer ring b, and thereby preventing the separation of
the two rings. The outer ring b is made in two (or more) segments, which
segments are connected together by screw bolts c passing through lugs f formed
on the said segments, washers g being interposed between the said lugs.
This arrangement admits of the outer ring b being fitted upon the inner ring a,
and screwed up by the bolts e from time to time to compensate for wear, the
washers g in that case being removed and replaced by thinner ones. A hole
marked in Figure 1 is formed in the inner ring a, through which oil may
be introduced between the two rings for the purpose of lubrication.
Having now described the nature of my Invention, and the manner in which
the same is to be performed, I wish it to be understood that I do not limit
myself to the precise details herein described and illustrated, as the same may
be varied without departing from the nature of my Invention; but I claim as
my Invention the improvements in wheeled carriages herein-before described
and illustrated in the accompanying Drawing, that is to say, connecting the
bodies of common road carriages with the axles carrying the fore wheels by
means of borizontal locking wheels or rings, constructed or arranged sub-
stantially in the manner described and illustrated, whereby the ordinary perch
bolt and wheel plate are dispensed with.
In witness whereof, I, the said Charles Bräutigam, have hereunto set
my hand and seal, this Twenty-sixth day of November, in the year of
our Lord One thousand eight hundred and sixty-six.
