IMPROVEMENTS IN AND RELATING TO BAND BRAKES FOR VELOCIPEDES
Year: 1885

page_text: I WALTER PHILLIPS of Coventry Manager to the firm of D. Rudge & Co.
Cycle Manufacturers, do hereby declare the nature of my said invention for
"IMPROVEMENTS IN AND RELATING TO BAND BRAKES FOR VELOCIPEDES," to be
as follows:-
On the axle carrying the driving wheel or wheels, or on the chain wheel
connected with the differential or "balance" gear I mount a brake drum of any
suitable diameter. When this drum is fixed to the axle as in the case of the
tricycle known as the "Coventry Rotary," I do not key it on, but I fix it in the
following manner whereby it may be easily fixed, or removed, or its position varied
as found necessary, or desirable.
I bore the boss of the drum with a taper hole and I provide a split coned collar
screwed at its smallest end and fitted with a nut. I place the split coned collar
on the axle and pass the boss of the drum over it and then tighten the boss
of the drum.on to the split collar by means of the nut, which locks the drum
firmly to the axle. By making the coned collar in halves and making the taper
hole in the boss of the brake drum large enough to pass over the bearing collars
on the axle I am able to fix the drum in position after the bearing collars are
fixed to the axle, and at any time to adjust its position. This part of my invention
it will be understood is only applicable to those machines in which the brake
drum is fixed to the axle. It will be obvious however that where the brake drum
is combined with the chain wheel and fixed to the axle, this method of fixing
may be adapted to the chain wheel, but where the driving power has to be
transmitted through this connection I prefer to fit a feather on the axle which
engages with a featherway cut in one part of the coned collar, or a key or dowel
pin may be fixed to the collar and a key way cut on the axle.
Round the brake drum is mounted in the usual manner a band or strap of steel
or other suitable metal lined with leather, that is to say, one end of the strap is
pivotted on a pin carried from the frame of the machine, and the other end is
pivotted on one end of a small bell crank lever, also pivotted to the frame of the
machine. On the vertical spindle of the left or "rest" handle, which consists of a
pear shaped handle mounted at the end of the horizontal arm of an inverted
L shaped rod, is a bracket on which is pivotted a brake lever extending to the end
of the pear shaped handle, at a convenient distance below it, so that it may be
•

is connected with the bell crank lever attached to the brake band by a coupling
rod adjustable in length for a purpose that will presently be made clear.
On the brake lever is pivotted in a suitable position a small pawl lever which
engages with teeth cut on the vertical arm of the handle rod, so that when the
brake lever is drawn up towards the "rest" handle, the brake is applied, and held
on, without any effort on the part of the rider, until it is released by pulling up
the pawl lever and so disengaging it from the teeth on the handle rod.
It will be seen that as the brake lever and ratchet lever are mounted on the rest
handle, and as the coupling rod between the brake lever and the bell crank is
adjustable in length, the "rest" handle can be adjusted in height to suit the
rider. More over as the connection between the brake lever and the brake strap
is adjustable in length the brake lever can be adjusted with respect to the "rest
handle, to give at all times the greatest power with the easiest position of the
hand.

Manufacturers 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 invention relates to the construction and arrangement of a band brake for
velocipedes, whereby its efficiency is increased and its construction simplified. In
the accompanying drawings throughout the views of which similar parts are
marked with like letters of reference. Fig. 1 is a side elevation, and Fig. 2 a front
elevation showing a brake constructed according to my invention, fitted to that
type of machine known as the "Coventry Rotary." On the axle A carrying the
driving wheel I mount a brake drum B of any suitable diameter, and fix it to the
axle in the following manner-I bore the boss of the drum B with a taper hole,
and I provide a split coned collar b screwed at its smallest end and fitted with
a nut b. I place the split coned collar on the axle A, and pass the boss of the
drum B over it, and then tighten the boss of the drum on to the split collar b by
means of the nut 6', which locks the drum firmly to the axle. By making the
coned collar in halves, and making the taperhole in the boss of the brake drum
large enough to pass over the bearing collars on the axle, I am able to fix the
drum in position after the bearing collars are fixed to the axle, and at any time to
adjust its position on the axle. This part of my invention it will be understood
is only applicable to those machines in which the brake drum is fixed to the axle.
It will be obvious however that where the brake drum is combined with the
chain wheel and fixed to the axle, this method of fixing may be adapted to the
chain wheel, but where the driving power has to be transmitted through this
connection, I prefer to fit a feather on the axle, which engages with a feather, or
key way, cut in one part of the coned collar; or a key or dowel pin may be fixed
to the collar and a key way cut on the axle.
Encircling the brake drum B is a band or strap C of steel or other suitable.
metal preferably lined with leather. One end of the strap C is carried by a pin c
fixed to the frame X of the machine, and the other end is attached to one end of
a small bell crank lever D which is pivotted on a pin d fixed to the frame of the
machine. On the vertical spindle E of the left or
"rest
"handle which consists
of a pear-shaped handle E' mounted at the end of the horizontal arm of an inverted
L shaped rod, is. a bracket F on which is pivotted a brake lever G extending to
the end of the pear shaped handle E¹, at a convenient distance below it, so that
it may be grasped by the fingers without taking the hand off the handle. The
brake G is connected with the bell crank lever D, by a coupling rod H which is
made adjustable in length for a purpose that will presently be made clear.
coupling rod H consists of two parts h and h¹. The part h is fitted to slide or
telescope within the part h¹, and the part h¹ is provided with a spring finger h³
carrying a small stud h³ which engages with one of a series of holes h' etc in the
part h. On the brake lever G is pivotted, by the pin g, a small pawl lever J
which engages with teeth e. e etc cut on the vertical E of the "rest" handle, so
The

page_text: that when the brake lever G is up towards the handle, the brake is applied and held
on without any effort on the part of the rider, until it is released by pulling up
the pawl lever J, and so disengaging it from the teeth e e etc on the handle rod E.
As the brake and ratchet levers are mounted on the "rest" handle, and as the
coupling rod between the brake lever and the bell crank is adjustable in length,
the "rest" handle can be adjusted in height to suit the rider without affecting the
"set" of the brake. Moreover, as the connection between the brake lever, and
the brake strap is adjustable in length the brake lever can be adjusted with respect
to the "rest" handle to give at all times the greatest power with the easiest
position for the hand.
It will be seen that the latter portion of my invention is applicable to all types
of tricycles, and other velocipedes, whether the brake drum is mounted direct on to
the axle, or forms part of the differential, or balance gear."
Having now particularly described and
invention, and in what manner the same is
I claim is:-
