Year: 1846

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
LAWRENCE TOBIAS TSCHUDY VON USTER, of the College for Civil Engineers,
Putney, in the County of Surrey, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Second day of June,
in the ninth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Henry Lawrence Tobias Tschudy Von
Uster, my exors, adññors, and assigns, Her especial licence, full power, sole
privilege and authority, that I, the said Henry Lawrence Tobias Tschudy
Von Uster, my exors, adññiors, and assigns, or such others as I, the said Henry.
Lawrence Tobias Tschudy Von Uster, my exors, adiñors, or assigns, should.
at any time agree with, and no others, from time to time and at all times
during the term of years therein expressed, should and lawfully might make,
use, exercise, and vend, within England, Wales, and the Town of Berwick-
upon-Tweed, my Invention of "IMPROVEMENTS IN APPARATUS OR MACHINERY
FOR MEASURING AND INDICATING THE DISTANCE TRAVELLED BY WHEEL CARRIAGES;"
in which said Letters Patent is contained a proviso that I, the said Henry
Lawrence Tobias Tschudy Von Uster, should cause a particular description

page_text: of the nature of my said Invention, and in what manner the same is to be
performed, by an instrument in writing under my hand and scal, to be
inrolled in Her said Majesty's High Court of Chancery within six calendar
months next and immediately after the date of the said in part recited Letters
Patent, as in and by the same, reference being thereunto had, will more fully
and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Henry Lawrence Tobias Tschudy Von Uster, do hereby declare that the
nature of any said Invention, and the manner in which the same is to be
performed, are fully described and ascertained in and by the following
statement thereof, reference being had to the Drawing hereunto annexed,
and to the figures and letters marked thereon, that is to say :-
My Invention consists in a mode of applying apparatus to carriages, so that
the distance which carriages having my apparatus applied have travelled may
be readily ascertained; but in order that my Invention may be better
understood I will proceed to describe the Drawing hereunto annexed, in
which the come letters are used to indicate similar
of the nature of my said Invention, and in what manner the same is to be
performed, by an instrument in writing under my hand and scal, to be
inrolled in Her said Majesty's High Court of Chancery within six calendar
months next and immediately after the date of the said in part recited Letters
Patent, as in and by the same, reference being thereunto had, will more fully
and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Henry Lawrence Tobias Tschudy Von Uster, do hereby declare that the
nature of my said Invention, and the manner in which the same is to be
performed, are fully described and ascertained in and by the following
statement thereof, reference being had to the Drawing hereunto annexed,
and to the figures and letters marked thereon, that is to say :-
My Invention consists in a mode of applying apparatus to carriages, so that
the distance which carriages having my apparatus applied have travelled may
be readily ascertained; but in order that my Invention may be better
understood I will proceed to describe the Drawing hereunto annexed, in
each of the Figures of which the same letters are used to indicate similar
parts.
DESCRIPTION OF THE DRAWING.
Figure 1 represents a plan of part of the framing of a carriage, with my
improvements applied thereto. Figure 2 is an end view of the same; and
Figure 3 is a side view of the bos or centre portion of one of the carrying
wheels, to which is affixed the sunil wheel a, for giving motion to the parts,
as I will now proceed to describe. The snail wheel a takes into and gives
motion to the pinion 6 on the axis c, carried by framing applied to the axle d
of the wheel to which the snail wheel a is applied. On the axis c is also
applied the bevil pinion c', which takes into and drives the bevilled pinion
e on the axis e, which is also carried by framing affixed to the axle d. The
axis e' is connected to the shaft f by an universal joint g, as is well under-
stood, and to the axis h by an universal joint i, so that although the axis h
is carried by a projection j from the body of the carriage, and a degree of
elasticity and changing of relative position will take place between the body
of the carriage and the axle d when springs are applied to the saine, such
variation will not affect the working of the apparatus; and further I have
formed the shaft f in two parts, one sliding within the other, yet so that in
whichever way ono part of the shaft is turned, the other part of the shaft f
will also turn in the same direction. The axis his carried as shewn by tho

page_text: body of the carriage, and upon this axis h is formed the screw wheel h', which
gives motion to a toothed wheel on the axis 1, which passes up through the
socket to give motion to any suitable arrangement of wheelwork for
registering the distance travelled, which apparatus or indicator may (on
continuing the already described method of giving motion thereto) be placed
in any desired position, either inside or outside of the carriage, and I prefer
that it should be so placed as that the passenger (if it be a public carriage)
may see the distance he has travelled; but as different apparatus for this
purpose have been proposed to be used, I have not thought it necessary to
show the same, and a person applying such index will be careful to calculate
the circumference of the wheel, having the snail a so that a due relation may
be maintained throughout the various wheels to the index.
I would however remark that I prefer that the index should be arranged with
two faces, the one looking into the interior of the carriage, so as to be seen
by the person riding therein, and the other externally, so as to be more
readily seen by the driver or other person having charge or use of the carriage.
Sometimes in place of applying the snail wheel to the side of the bos of a
wheel, as shewn at Figure 8, I apply it in the form of a screw wheel on
the periphery of the bos, or I apply it to the framing of the carriage, and
apply it to the carrying wheel, in connection therewith a stop or other
suitable clutch movement, so that the wheel may be removed to be cleaned.
or otherwise without removing the screw wheel, and when again applied
thereto it will give motion to the parts in a similar manner to that above
described. In every case I as much as possible enclose the parts likely to
be affected by dirt and dust.
Having thus described the nature of my said Invention, and the way in
which the same is to be carried into effect, I would have it understood that
I do not confine myself to the exact details shown and described, so long as
the peculiar character of the Invention, which consists in giving motion to
apparatus for measuring and indicating the distance travelled by carriages, by
means of a snail or screw wheel, and parts connected therewith, are retained,
as above described.
In witness whereof, I, the said Henry Lawrence Tobias Tschudy Von
Uster, have hereunto set my hand and seal, this Second day of
December, in the year of our Lord One thousand eight hundred and
forty-six.
H. L. T. TSCHUDY VON (L.S.) USTER.
