PROVISIONAL SPECIFICATION.
New or Improved Combined Apparatus for Applying a Brake at
Stated Speeds, Recording Distance Travelled, and Indicating
Rate of Speed, applicable to Auto-cars, Cycles, and other
Vehicles.
I EDWARD HENRY PREW of 1 Corporation Street Barnsley in the County of
York, Schoolmaster do hereby declare the nature of this invention to be as
follows:-
My present invention has for its object to so arrange and combine an apparatus
which will automatically apply a brake to an auto-car cycle or other vehicle when
travelling at any desired limit of speed and will also indicate the speed and record the
distance travelled and my said improved apparatus consists essentially of a ball
governor which revolves around a hollow vertical spindle the said governor being
driven from one of the wheels of the cycle or vehicle by means of a band and bevel
gearing or by any other well known driving mechanism.
The hollow spindle aforesaid has a slot formed in its side through which protrudes
the extended part of a rod which passes up the centre of the hollow spindle, the upper
part of said rod being connected to a pivotted pointer or indicator which points at the
rate of speed the cycle is travelling upon a suitable dial.
The said protruding part of rod may have a runner fitted thereto and it bears upon
the movable lower collar of the governor the rod being thereby caused to travel
upwards and downwards in accordance with the movement of the governor as will be
obvious. The lower or loose collar of the governor may be formed with a vertically
adjustable collar or may have a series of annular grooves which receives the end of a
pivotted brake-bar in such a manner that as the collar will vary in its upward and
downward movement with the speed of the governors the brake will be applied in
accordance with the limit of speed required that is to say the brake is secured to one
end of the bar which is pivotted to a frame which carries the governor and the
opposite end of bar extends to the loose collar of said governor and this end can be
set so that the brake will come into action at any regulated speed of the governor the
speed increasing in accordance with the rising of the collar and the brake varying in its
action according to the elevation of that end of the bar which is connected to or bears
in the adjustable collar or any of the annular grooves.
The vertical rod running within the hollow spindle extends beyond the top of said
spindle and either the hollow spindle or said rod receives a pinion wheel and by the
medium of well known mechanism it causes an indicator to record the amount of
distance travelled upon a dial.
Where my said invention is applied to a cycle it is preferably fixed so as to be
operated by the boss or other revolving part of the front steering wheel and the brake
is applied thereto in manner herein before described.
The indicator and dial for either the distance recorder or speed indicator may be so
placed in positions with a lamp that at night the said dials may be easily observed by
the rider or driver.
I would here point out that my invention is in the combination with the governor
of an operating central rod which works a pivotted indicator or pointer upon a dial
and this where preferred may be used as a speed indicator per se, and also in the

page_text: combination of said operating either central rod or hollow spindle with well known
distance recording mechanism which may also be used as a distance recorder per se,
and in the combination of a governor with an adjustable loose collar or collar with
annular grooves for operating a pivotted brake bar and brake which may act as
an automatic brake per se, although therefore I have described my apparatus in
combination so as to attain the three objects specified where desired any one of the
arrangements may be used separately as will be well understood.

New or Improved Combined Apparatus for Applying a Brake at
Stated Speeds, Recording Distance Travelled, and. Indicating
Rate of Speed, applicable to Auto-cars, Cycles, and other
Vehicles.
I EDWARD HENRY PREW, of 1 Corporation Street, Barnsley, in the County of
York, Schoolmaster, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement:-
My present invention has for its objects to so arrange and combine an apparatus
which will automatically apply a brake to an autocar, cycle or other vehicle at any
required stated speed, or travel, and will also indicate the speed the vehicle is
travelling at; and where desired will also record the distance travelled, and these
objects I attain by means of the mechanism substantially as hereinafter set forth and
described with reference to the accompanying sheet of drawings, which latter are to
be considered as typical illustrations of my improvements only, inasmuch as the same
may obviously be modified in size, shape and arrangement with ut departing from the
essential novel features of my invention.
Fig. 1 is a sectional elevation of my improved apparatus arranged in combination
for the three objects before stated.
Eig. 2 is a sectional plan taken on line bb and
Fig. 3 is a sectional plan taken on line a a of said Fig. 1.
Fig. 4 is a side view of apparatus shown at Fig. I applied complete with brake and
driving cord to a cycle.
Fig. 5 is a front view of my apparatus adapted for a sight speed indicator only.
Fig. 6 is a front view of a modified form of sight speed indicator pointer, and dial,
and Fig. 7 a plan of same.
Fig. 8 is a front view of said sight speed indicator applied to an auto-car or other
vehicle, and Fig. 9 is a side view of same.
Fig. 10 is a side view showing in detail a modified means of driving my improvement
from the tyre of a cycle or vehical wheel.
Similar letters of reference denote coresponding parts in each view.
My improved apparatus consists essentially of a hall governor C of any desired type
or pattern, which revolves upon and with a hollow spindle c', which latter may be
driven by a worm d and the worm wheel d' and pulley d by means of a cord d³
running over the boss, or a pulley fitted thereto, of the cycle steering wheel E. Or it
will be obvious that bevel gearing as shown at Fig. 8 may be used, or friction
gearing as shown at Fig. 10, or any other well known driving mechanism.
The hollow spindle c' has a slot c² formed in its side through which extends a pin j'
fixed or screwed to or made with a rod J which passes up the centre of hollow

page_text: spindle c. The upper end of rod J has fixed to it a pointer which moves upon a.
graduated dial K marked with the rates of speed of travel of the cycle auto-car or
vehicle. The pin j' may have a runner 3 fitted to its end where preferred, and it
bears upon the movable lower collar of the governor, the rod being thereby
caused to travel upwards and downwards in accordance with the speed of the
governor C as will be obvious.
The said moveable collar c³ has its outer circumference formed with a screw whereon
is screwed an adjustable brake operating collar e which is formed with an annular
groove for the reception of the fork end m' of an extension of the rod which.
operates the brake bar m³, the latter being pivotted to a fitting m* fixed to the steering
part of the cycle, and which with the fitting m and extensions, carries my improved
combined apparatus as shown at Fig. 4.
As the governor C increases in speed in ratio to the travelling speed of the cycle, it
lifts the loose collar e with the adjustable brake operating collar c and likewise the-
rod m³ and operates the brake bar m³ and applies the brake M. In order to auto-
matically apply the brake M at any desired limit of speed, a graduated scale or dial N
is fitted opposite to the adjustable collar c, and the upper part of the collar is made-
with an annular pointer c which points to a number or rate of speed marked on said
scale N. By these means it will be obvious that by screwing the collar c* upwar.is or
downwards the brake will act automatically at any indicated rate of speed, so that by
this means any cycle or auto-car can be regulated so that it is impossible to run at any
speed beyond that to which the apparatus is set, as the brake will vary in its action
according to the elevation of the fork end m² of the brake operating mechanisın.
The hollow spindle c¹ may receive a pinion p near its upper end which gears with
and operates a nest of wheels arranged in a well known manner for recording the
distance travelled and operating pointers or hands p' working around dials as shown.
at Fig. 2.
Referring to Figs. 6 and 7, the dial K is made with a slot k within which is carried
the index supported in position by a light spring arranged at the back.
The upper end of the rod J bears under the index . By this arrangement the
highest speed attainable in any journey of the cycle is recorded as the index will
remain although the rod J lowers.
I prefer to enclose my apparatus in a casing Q the upper part having lid g
arranged with a glass q so that the distance travelled and rate of speed may be
observed at all times.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. In combination with a governer of an operating central rod which works an.
index or indicator upon or near a dial or graduated plate marked with rates of speed
substantially as described and for indicating the rate of speed a cycle moto-car or
other road vehicle is travelling.
2. The combination with a governor of an operating central rod and hollow spindle
with well known distance recording mechanism substantially as described.
3. The combination with a governer of a loose collar arranged with an adjustable
brake operating collar having a connection of the brake mechanism running thereon..
The adjustable brake operating collar having an annular or other or other pointer or
index part moving near a fixed graduated scale or dial marked with indications of rate
of speed for the purpose of adjusting the brake mechanism to be applied automatically
at any desired rate of speed substantially as described.
