IMPROVEMENTS IN CYCLOMETERS
Year: 1884

page_text: I SAMUEL HILL of New Street in the City of Worcester Umbrella Manu-
facturer do hereby declare the nature of my invention for IMPROVEMENTS IN
CYCLOMETERS to be as follows:-
My invention relates to an Indicator for the purpose of registering Revolutions,
Yards, Furlongs, Miles, tens, Hundreds, and Thousands of Milos.
The indicator consists of a train of wheels and pinions, the axles of which carrios.
the registering hands in front of the indicating dials.
The motion is given to the wheels and pinions and registering hands by means
of a leading screw and worm wheel. The one end of the leading screw is actuated
upon by a paul or catch which is fixed in the hub of the main carrying or'
Driving wheel of the Tricyle or Cycle Machine or other vehicles.
The action of the Indicator is as follows. The case which contains all the
working parts of the indicator is fixed on the frame, and on the centre line of the
axle and hub of the main carrying or driving wheel of the Cycling Machine, or in
any other suitable position.
In the hub of the main carrying or driving wheel is fixed a paul or catch. The
paul or catch on the completion of each revolution of the main carrying or driving
wheel comes in contact with a five spur pinion wheel which is fixed on, the bottom
of the main driving screw of the indicator, by this arrangement the driving screw
of the indicator makes one revolution to five of the inain carrying or driving
wheel of the Cycling Machine.
D
The motion of the indicator hands in front of the registering dials is as follows."
On the first axle which carries the worm wheel that gears into the main driving
screw of the indicator is fixed a small pinion wheel, which gears into the spur
wheel that revolves the second axle, and upon which is fixed the hand opposite the
dial which registers the yards furlongs and mile or the revolutions.
The second axle also is fitted with a pinion which gears into a spur wheel in the
proportion of ten to one namely the second axle will make ten revolutions to one
of the third axle.
The third axle carries the hand for registering the mileage up to ten miles. And
it is also fitted with a small pinion which gears into the large spur wheel on the
forth axle. This pinion and spur wheel is also in proportion of ten to one, there-
fore the indicating hand on the forth axle will register the tens up to one hundred
miles

-
The dial hand for registering the hundreds and up to one thousand miles is
worked by means of a spur wheel fitted with a sleeve, and through which sleeve
the third axle passes.
The outer end of the sleeve of this spur wheel carries the hand for indicating the
hundreds and up to one or more thousands of miles. This sleeved spur wheel is
fitted with ten or more teeth, and is worked by a single catch fixed on the forth
axle, therefore the said spur wheel and single catch is also in proportion of ten to
one, or otherwise as may be required.
On the completion of the revolution of the forth axle upon which the hand is
fixed for indicating the one hundred miles, the catch fixed thereon will operate
Bimultaneously upon the spur wheel and sleeve at the completion of each hundred
miles traveled.
The spur wheel which works the hand for registering the hundreds and up to
one or more thousand miles is kept firmly in its place by means of a side spring
which presses the spur wheel against the side of the wheel frame thus preventing
any possibility of the spur wheel revolving except when the catch comes in contact
with it.
For the convenience of setting the indicator at zero at any moment the following
arrangement have been made, namely. The first axle that carries the worm wheel
and which gears into the main driving screw of the indicator is made with a
sliding motion. On the one end of the axle is fixed a finger knob, and the opposite
end of the axle is fitted with a spirial spring, that presses against the side of the
worm wheel and the inside of the wheel frame.
The end of the third axle is made to receive a key for the purpose of setting all
the hands at zero on the registering Dials. To do this, the knob on the end of the
worm wheel axle must be pressed by the finger, and by doing so, the worm wheel
is thrown out of gear from the main driving screw of the indicator, and by turning
the key on the third axle, the whole of the hands can readily be set at zero on each
dial, then by releasing the pressure of the finger from the knob the worm wheel is
instantly thrown, into gear again by means of the spiral spring herein before
mentioned.
The Indicator caso is fitted with a socket and screw for attaching it to the
carrying bracket fixed on the frame of the Cycling Machine.
The Dial and all the working parts are all protected by a glazed frame screwed
into the case.

I, SAMUEL HILL of New Street in the City of Worcester-Umbrella Manu-
facturer do hereby declare the nature of my invention for IMPROVEMENTS IN,
CYCLOMETERS and in what manner the same is to be performed, to be particularly.
described and ascertained in and by the following statement:
My invention relates to an indicator for the purpose of registering revolutions,
yards, furlongs, miles, tens, hundreds & thousands of miles.
The indicator consists of a five spur pinion wheel and a train of wheels and
pinions, the axles of which, carries the registering hands in front of the indicating
dials.
The motion is given to the wheels and pinions and registering hands by means.
of the leading screw C. and worm wheel E. The one end of the leading screw C
is actuated upon by the point b which is made on the clip b, which is fixed on the
hub of the main carrying or driving wheel of the Tricycle or Cycling Machine.or
other Vebicles.
On reference to the Drawings it will be seen that the case A Fig 1 & 2 con-
taining all the working parts of the Indicator is fitted with two hanging links a' a¹
and is hung loosely on the centre part of the hub a. Also on the hub a. is ridgedly
fixed the Clip b. on which is made the point 61. On the completion of each revolution
of the main Driving Wheel of the Cycling Machine the point b actuates upon the
five spur pinion wheel B, which is fixed on to the end of the main driving screw
of the Indicator.
a
By this arrangement the main driving screw C of the indicator makes one
rovolution to five of the main carrying or driving wheel of the Cycling Machine.
The motion of the Indicator hands in front of the registering dials is as follows
On the first axle D Fig 3 & 4. and which also carries the worm wheel E
Fig 3 & 4. that gears into the main driving screw C of the Indicator is fixed the
small-pinion wheel F which gears into the spur wheel F Fig 3 & 4 and which
revolves the second axle G. Fig 4. And upon which is fixed the hand G. Fig 1.
opposite the dial which registers tho yards, furlongs & mile, or revolutions.
The second axle G. shown in Fig 4. is fitted with the pinion H Fig 4 and which.
gears into the spur wheel I Figs 2, 3 & 4. This spur wheel and pinion is in,
proportion of ten to one. Namely the second axle G. will make ten revolutions to
one of the third axle J.
The third axle J Figs 1. 2 & 3 carries the band K which is placed in front of the
centre dial for registering the Mileage up to ten or more miles as shown in Fig 1.
This axle also is fitted with a small pinion wheel L Figs 3 & 4 which gears
into the large spur wheel M which is fixed on the fourth axle N as shown in
Figs. 3 & 4.
.
Therefore the
The pinion L& spur wheel M is also in proportion of ten to one.
indicating hand N on the fourth axle will register the tens up to one or more
hundreds of miles as shown on the dial Fig 1. The Dial hand X in front of the
centre dial is for the purpose of registering the mileage from one hundred up to
one or more thousands of miles, and is worked by means of the spur wheel x¹
Figs 3 & 4 and which is fitted with a sleeve through which the third axle J passes.

page_text: The outer end of the sleeve is attached to the spur wheel z¹ and the hand which
indicates the mileage from one hundred up to one or more thousands of miles, as
shown on the centre dial Fig 1. The sleeved spur wheel ¹ Fig 3 & 4 is fitted with
ten or more teeth and is worked by the single catch o Fig 3 & 4 and is fixed on the
fourth axle N.
The sleeved spur wheel and singlo catch is also in proportion of ten to one or
otherwise as may be required. The hand x placed in front of the centre dial is
revolved as follows.
On the completion of the revolution of the fourth axle N upon which the hand N
is fixed for indicating the one hundred miles the single catch o which is fitted
thereon will operate simultaneously upon the spur wheel and sleeve x at the com-
pletion of each hundred miles travelled-The spur wheel & sleeve which carries
the hand is kept firmly in its place by means of the sido spring P Figs 3 which
*presses the spur wheel & sleeve against the side of the wheel frame o thus preventing
any possibility of the spur wheel revolving except when the catch o comes in
contact with the wheel -For the convenience of setting the indicator at zero at
any moment the following arrangement have been made. Namely the first axle D
Figs 3 & 4 and which carries the worm wheel É and which gears into the main
driving screw C of the Indicator, is made with a sliding motion, on the end of the
axle D is fixed a finger knob T Figa 2 & 3 and on the opposite end of the axle D
the spirial spring R Fig 3 is fixed, which presses against the side of the worm
wheel E and the inside of the wheel frame Q. The end of the third axle J is made
to receive the key S Fig 3, which is for the purpose of setting all the hands at zero
on the registering Dials, To do this the knob T Figs 2 & 3 which is fitted on the
end of the worm wheel axle D must be pressed by the finger, & by so doing the
worm wheel E is thrown out of gear from the main driving screw C of the
indicator and by turning the key on the third axle J the whole of the hands can
readily be set at zero on each dial, then by releasing the pressure of the finger from
the knob T the worm wheel E is instantly thrown into gear again by means of
the spiral spring R hereinbefore mentioned.
The indicator case A is fitted with a glass front and frame whereby all the dials
and all working parts are protected.
Having now particulary described and ascertained the nature of my said
Inprovement and in what manner the same is to be performed I declare that what
I claim is
First The manner in which the motion is transmitted to the indicator by means
of the clip & point ridgedly fixed on the hub & the manner in which the indicator
is carried on the hub of the main carrying or driving wheel of the Cycling machine
or other vehicles. And also the action of the point b with the spur wheel B which
is fitted on the end of the main driving screw C of the indicator.
Second The combined arrangement by which the worm wheel can be thrown
out of gear to admit of the whole of the dial's hands been set at zero as herein
described.
Third I claim as a novelty the combined general arrangement of the parts
and action thereof as herein specified and shewn on the drawings herewith
attached.
