I, WILLIAM RIXOM, of 1, Merthyr Terrace Castelnau, Barnes, in the County of
Surrey, Coach Builder do hereby declare the nature of my invention for AN
IMPROVED BREAK FOR ROAD AND OTHER VEHICLES to be as follows:-
This Invention is an automatic Break specially designed for Carriages and other
Road Vehicles but it is also applicable for Railway Carriages, Trycicles, Cranes and
all classes of revolving wheels in machinery or otherwise requiring the application
of a Break.
The principles upon which this Break is constructed may be best discribed in its
application to an ordinary Road Carriage wheel.
In this case I apply my Break on the inner side of the nave of the wheel.
To accomplish this I increase the width of the ordinary stock hoop to about two
inches broad, this may be more firmly secured to the nave than usual, if required
by lugs or other suitable arrangement I surround this stock hoop for about one
half its circumferance with a strap of Iron or other suitable material preferably
steel, this may be lined with Leather, wood or other suitable material to increase
the grip on the stock hoop. The lower end of this strap I attach to a stud pro-
jecting from a short arm which I fix by a clip to the axle preferably between the
spring and the collar on the axle so as to be as close to the nave as possible To
the top or other end of this strap I attach a shoe or pan of Iron or other suitable
material which I curve to follow the strap above named round about another third
of the circumferance of the stock hoop. This shoe or pan I so arrange that when
in position while the top end will be about one inch from the surface of the stuck
hoop the bottom end will be about one & a half inches from the same surface or
thereabouts. In this pan I have a Roller of Iron or other suitable material, about
one and a half inches in diameter, and of a length just to fit in this pan from side to
side that is about one and a half inches, so that it may run freely from the lower
to the upper end of the pan, this strap and pan are so placed that the pan shall be
at the rear of the nave. The lower end of this pan I connect by a short adjustable
link, to a short crank on the end of a rocking shaft which is passed through the
bracket or arm which holds the lower end of the strap. This Crank is so adjusted,
that when the rocking shaft rotates through about one hundred Degrees it brings
the aforesaid pan, up to, or away from the surface of the stock hoop.

page_text: This rocking shaft is so adjusted that when it turns 'round so that the crank on
its end pulls the pan into position, the crank just named will be on its dead centre
in relation to the link which connects it to the pan, and the Roller, which runs in
the pan, will then just touch the surface of the stock hoop, then as the wheel
revolves it causes the Roller to run up towards the upper end of the pan and in so
doing (there being less space between the upper end and the surface of the stock
hoop than at the lower) it forces the upper end of the pan further away from the
surface and in so doing it tightens the strap on the stock hoop, and then the two
together (Strap & Roller) effectually check and stop the rotation of the wheel.
I further provide the rocking shaft above mentioned with a suitable spring to
throw it into such a position as will bring the Roller in the pan in contact with the
stock hoop. On this rocking shaft I fix a small lever (in the middle or otherwise)
to the end of this lever I attach a cord or light rod, which when pulled cause the
rocking shaft to rotate and this throws the Break off but directly this cord or rod
is released the spring on the rocking shaft causes it to rotate and bring the Roller
in the pan into contact with the stock hoop, the rotation of the wheel then applies
its own break as discribed.
My Invention further provides a suitable pedal, which may be placed on the
foot board upon this pedal the drive will place his foot with a small pressure when
he desires to remove the break from the wheel or wheels Then by touching a
small knob (which may bo placed beside the pedal) with his foot the cord or
connecting rod is released and the break is at once applied without any manuel
labour.
If prefered in place of the pedal just mentioned a small lever may arranged at
the side of the Coachman's seat for controling the break by hand instead of the
foot.
This break may be applied to one or both hind wheels (or all four if required)
when applied to both hind wheels, the rocking shaft will reach from side to side,
having a crank on each end, one for each wheel.
A modification of this arrangement may if required bo adapted for application at
the Tyre of the wheel, but its application to the nave is preferable.

other Rotating Parts of Machinery.
I WILLIAM RIXOм of 1 Merthyr Terrace Castlenau Barnes in the county of
Surrey Coach Builder do hereby declare the nature of my invention for AN
IMPROVED BREAK FOR VEHICLES AND FOR PULLEYS SHAFTS AND OTHER ROTATING
PARTS OF MACHINERY and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention is an automatic Break specially designed for carriages and other
Road Vehicles but it is also applicable for Railway Carriages Tricycles Cranes and
all classes of revolving wheels in machinery or otherwise requiring the application
of a Break.
The principles upon which this Break is constructed may be best described in its
application to an ordinary Road Carriage Wheel Figure 3 shews a side view of
my invention so applied. Figure 2 shews the apparatus as seen from the outside
of the Wheel and Figure 1 shews the apparatus as seen from the inside the axle
of the carriage being shown in section In one case I apply my Break on the inner
side of the nave.of the wheel. To accomplish this I increase the width of the
ordinary stock hoops to about two inches broad this may be more firmly secured to
the nave than usual if required by lugs or other suitable arrangement I surround
this stock hoop A for about one half its circumference with a strap B of Iron or
other suitable material preferably steel this may be lined with leather wood or
other suitable material to increase the grip on the stock hoop. The lower end of
this strap I attach to a lug projecting from a short arin C which I fix by a clip
or clips to the axle D preferably between the spring and the collar on the axle so
as to be as close to the nave as possible. To the top or other end of this strap
I attach a shoe or pan E of iron or other suitable material which I curve round
about another third of the circumference of the stock hoop. This shoe or pan I so
arrange that when in position the top end will be about one inch from the
surface of the stock hoop and the bottom end will be about one and a half inches
from the same surface or thereabouts. In this pan E. I place a ruller F. of iron or
other suitable material about one and a half inches in diameter and of a length
just to fit in this pan from side to side that is about one and a half inches so that
it may run freely from the lower to the upper end of the pan. This strap B. and
pan E. are so placed that the pan E. shall be at the rear of the nave. The lower end
of this pan EI connect by a short adjustable link G. to a short crank H. on the
end of a rocking shaft I. which is passed through the bracket or arm C. which holds
the lower end of the strap B.
This crank H is so adjusted that when the rocking shaft I. is made to rotate
through about one hundred degrees it brings the pan E. either up to or away from
the surface of the Stock Hoop A.

page_text: This rocking shaft I. is so adjusted that when it turns round and the crank H.
pulls the pan E. towards the stock hoop the roller F. will just touch the stock hoop
when the crank H. is on its dead centre in relation to the link G and shaft I. then
as the wheel revolves it causes the Roller F. to run up towards the upper end of the
pan E. and in so doing (there being less space between the upper end of the pan
and the surface of the stock hoop than at the lower) it forces the upper end of the
pan further away from the surface and in so doing it tightens the strap B. on the
Stock hoop and the two together (strap and roller) effectually check and stop
the rotation of the wheel.
I provide the rocking shaft I. above mentioned with a suitable spring J. so that
when it is desired to put on the break all that is required is to slack the string L.
the spring J. then throws the apparatus into the position shewn in Figure 1 and
the roller then rolls up the pan and puts the break on.
The string L. is attached at one end to a small lever K. keyed on the shaft I.
and at the other end to a treadle which will be hereafter described placed within a
convenient distance of the drivers foot.
I prefer connecting my break with the Driver by means of a cord or light rod as
above described so that the break is put on by the operation of a spring but in
some cases I prefer to release the break by the operation of a spring and to put it
on by pressure exerted by the driver by his foot or otherwise.
My invention further provides a suitable pedal shewn in Figures 4 and 5 which
may be placed on the footboard the Driver will press this pedal down when he
desires to remove the break from the wheel or wheels and by touching a small
knob (which may be placed beside the pedal) with his foot the pedal and the cord
connected to it are released and the break is at once applied without any manual
labor.
If preferred in place of the pedal just mentioned a small lever may be arranged
at the side of the Coachman's seat for controling the break by hand instead of
the foot.
This break may be applied to one or. both hind wheels or all four if required.
A modification of the arrangement may if required be adapted for application at
the Tyre of the wheel but the application to the nave is preferable.
a, a, is a lever or treadle with a suitable tread for the foot at the end shewn at a
the end of this lever works in a socket 6. which is itself centered upon a pin c.
Projecting from the lever a. a. is a short arm a¹ having a knob or head at its end
as shewn. d is a lever or arm fixed to the end of a. a.-e is another lever or arm
working freely on centre pin c. To the end of f. of the arm e. is attached the cord
or rod for working the Break.
g. is a notch on the arm e. to receive the end of arm d.-i is a spring for keeping
the arm & pressed behind the notch g. on the arm e. and the quadrant j attached
thereto at the same time supporting the whole weight of the lever a. a. and its
attachments.
kis a stop to prevent the arm e from moving too far.
1. is a catch for holding down the treadle a. a.
The action of the arrangement is as follows.
When in the position shewn in the Drawing Figure 2 the break would be off.
To apply the break the foot would be placed on the knob or tread at the end of
the short arm a¹. This would pull the lever d out of notch g on the arm e thus
the arm e is left free to fly back to the stop k. by the pull of the rod or cord at f.
The string being thus released the break is applied as before described.
As soon as the foot is taken from the knob or tread on short arm a¹ the lever or
treadle a a is lifted by the spring i. until the lever d is behind notch g..
When the break is required to be taken off the foot is placed on the tread a' and
the lever or treadle a a is pressed down until caught by catch 7. which holds the
break off until it is again required.

page_text: 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
Firstly. The use of a roller for the purpose of tightening a break strap substan-
tially as described.
Secondly. The apparatus for releasing and tightening the cord substantially as
described and shewn in Figures 4 and 5.
