IMPROVEMENTS IN MACHINERY FOR INDICATING THE DISTANCE TRAVELLED BY VEHICLES
Year: 1876

page_text: LETTERS PATENT to Sidney Johnson, of 67, Strand, in the City of Westminster,
66
for the Invention of IMPROVEMENTS IN MACHINERY FOR INDICATING THE
DISTANCE TRAVELLED BY VEHICLES."
Sealed the 8th August 1876, and dated the 9th February 1876.
PROVISIONAL SPECIFICATION left by the said Sidney Johnson at the Office
of the Commissioners of Patents on the 9th February 1876.
SIDNEY JOHNSON, of 67, Strand, in the City of Westminster.
"IMPROVEMENTS
IN MACHINERY FOR INDICATING THE DISTANCE TRAVELLED BY VEHICLES."
The Invention consists in giving motion to any suitable indicator apparatos
fixed to the wheel of a vehicle, as and when said wheel moves by means of a ball
allowed to travel freely by gravity in a closed annular chamber, and made to
impinge at every revolution of the wheel of the vehicle on tle blade or blades of a
wheel situated partly within such annular chamber, and partly within the chamber
formed and surrounded by said annular chamber, and holding any desired recording
apparatus, the fan wheel being mounted on a toothed pinion working in cogged
wheels which are proportioned to move and register on a suitable dial feet, yards,
miles, and so forth.
The improved machinery can be conveniently applied to the wheel of any vehicle
by screwing or otherwise fixing it on to the cap of such wheel, or it may be
fixed on other convenient part, the recording and indicating apparatus being
proportioned to the circumference of the wheel to which it is to be used.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Sidney Johnson in the Great Seal Patent Office on the 8th August
1876.
SIDNEY JOHNSON, of 67, Strand, in the City of Westminster.
"IMPROVEMENTS
IN MACHINERY FOR INDICATING THE DISTANCE TRAVELLED BY VEHICLES."
My Invention consists in giving motion to any suitable distance indicating
apparatus fixed on the wheel of any vehicle, as and when such wheel revolves by
means of a ball allowed to travel freely by gravity in a closed annular chamber, and
Price 71

page_text: made to impinge at every revolution of such wheel on the blade or blades of a
driving wheel situated partly within said annular chamber mounted on a toothed
pinion, and when desired with a ratchet and pawl to prevent back movement, and
driving any indicating and registering machinery properly proportioned to the wheel
of the vehicle, and to the movement and registration which it may be desired to
indicate.
The accompanying Drawings will show how my improvements may be readily
performed.
Fig. 1 is a sectional side elevation: and Fig. 2, a plan view in said views.
A is the annular chamber; B, the ball; C, the bladed driving wheel; D, pinion
of same; E, ratchet and pawl to prevent backward movement of C; F, an inner
chamber in which the indicating and registering apparatus, which may be of any
ordinary description suitable for the purposes intended may be placed; G, studs
impinging on a rubber band H which is introduced as a packing to diminish
concussions, and placed between the outer side of the annular chamber A and a ring
clip or band, this latter ring being fixed direct to the wheel of the vehicle or on
the axle thereof.
I claim as my Invention the combination in machinery for indicating the distance
travelled by vehicles of the annular chamber A, and the ball B working by gravity
therein and actuating the bladed driving wheel C, together with the rubber H, all
substantially as and for the purposes described and set forth.
In witness whereof, I, the said Sidney Johnson, have hereunto set my hand
and seal, this Fourth day of August, in the year of our Lord One thousand
eight hundred and seventy-six.
SIDNEY JOHNSON. (L.S.)
