A Speed Indicator for Cycles, Motor Cars, Carriages and such like.
I, Ross FRANKLIN MOORE, Major, Royal Engineers (retired list), 78, Bensham
Manor Road, Thornton Heath, Surrey, do hereby declare the nature of this inven-
tion to be as follows:-
On a metal spoke fitted to one of the revolving wheels of the cycle, motor car,
carriage or such like is fixed a spiral spring. This spring at one end is attached
to the axle of the wheel and at the other carries a comparatively heavy metal
A convenient form for
weight. To the metal weight is fixed a projecting arm.
the weight is that of a metal cylinder to contain the spring as described in my
Patent No. 22578 of 1897.
At the side of the wheel of the vehicle is a bar which is attached radially to
the non-revolving part of the axle and any convenient part of the framework of
the vehicle.
On the bar is a bell capable of being moved up and down for adjustment.
The bell has a long armi, parallel to the bar, which is arranged to ring the bell
when the projecting arm from the spring comes in contact with it.
A convenient
A scale is marked on the bar for the adjustment of the bell.
scale is one showing miles per hour at which the vehicle is travelling.
When the wheel of the carriage revolves its centrifugal force acting on the
weight at the end of the spring causes the spiral spring to stretch in relation to
the speed and rings the bell.

A Speed Indicator for Cycles, Motor Cars, Carriages and such like.
I, Ross FRANKLIN MOORE, Major, Royal Engineers (retired list), 78, Bensham
Manor Road, Thornton Heath, Surrey, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:
On a wire spoke, A, fitted to one of the revolving wheels of the carriage is fixed
a spiral spring S. This spring is enclosed in a metal cylinder, E, which is just
large enough to admit of free play for the spring inside. The spring, S, at one
end is attached to a block, C, which is clamped on to the axle by the clamps D.
The other end of the spring is attached to the head of the containing cylinder E,
as described in my Patent No. 22578 of 1897 (Fig. 1).

page_text: On the outside of the cylinder, E, is a block, G, which carries an arm F.
At the side of the wheel of the vehicle is a bar, H, which is attached radially
to the non-revolving part of the axle and to any convenient part of the frame-
work of the vehicle, (see Figures 1 & 2).
On the bar is a bell, I, which is capable of being moved up and down for
adjustment.
The bell, I, has a long arm, J, fixed to the clapper of the bell and parallel to
the bar, H.
A scale is marked on the bar, H, for adjusting the position of the bell.
Figure 3 shows a clamping arrangement which can be used for fixing the wire
spoke, A, to the spokes of the wheel at the end away from the axle.
When the wheel of the carriage revolves the centrifugal force acting on the
weight of the cylinder, E, causes the spiral spring, S, to stretch When sufficiently
stretched to admit of the arm, F, coming in contact with the arm, J, the bell is
rung.
The sounding of the bell indicates that the speed arranged for by the scale has
been attained.
A convenient scale is one showing miles per hour at which the vehicle is travel-
ling.
The scale is arrived at practically by running the wheel on which the indicator
is mounted at the right number of revolutions for the different rates of speed or
by actual trial by time and distance on the road.
The scale for the adjustment of the position for the bell, I, can be arranged in
a convenient position on a level with the rider. This will enable the rider to alter
the speed at which the bell will ring when on his seat without dismounting.
To do this the bell, I, is fixed at one end, of a sliding rod and the speed scale
at the other. The sliding rod telescopes on to a short length at the bottom end
which is attached to the axle; at the upper end, where the scale is fixed to it,
it passes through a guide block which is clamped to the framework of the vehicle.
The rod can be moved up and down through the guide block by means of a rack
and pinion to be worked by the fingers or any such like arrangement.
If a telescope joint is provided near the top of the rod this will admit of the rod
being lengthened or shortened to suit the height of the vehicle as required.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
-
A speed indicator for cycles, motor cars, carriages and such like substantially
as herein described and illustrated in the accompanying drawing.
Dated this 30th day of June 1898.
