PROVISIONAL SPECIFICATION.
Improvements in connection with Brakes for Velocipedes.
I, The Right Honourable Sir JOHN DOUGLAS SUTHERLAND CAMPBELL,
commonly called the Marquis of Lorne, K.T., of Kensington Palace, in the County
of London, do hereby declare the nature of my invention to be as follows:-
My invention relates to improvements in connection with brakes for velocipedes
and has for its object to provide improved means for very readily and efficiently
applying a brake by the direct application of the rider's weight.
I will describe my invention for use in applying the brake to the rear wheel
of a bicycle for which it is more especially intended.
According to my invention I provide at the rear of the saddle a protuberance
or protuberances or pad or pads or other device (I will for brevity refer to it as
a pad) and to this I connect the upper end of a brake lever, rod or equivalent
device, the lower end of which is connected to the brake so that the said brake
may be applied by the rider shifting backwards and thereby partly or wholly
transferring his or her weight from the saddle to the said pad, the brake being
then operated by a rod or otherwise either vertically or in a diagonal direction on
the wheel.
According to one arrangement I may use a coiled spring or other like device.
fitted in a tube or the like, so as to allow for the return of the pad to its normal
or raised position and to obviate a too sudden application of the brake. The
brake is removed by the rider shifting his or her body forward on the saddle
so that the weight of the body is removed from the pad which, under the influence
of the aforesaid spring, or other device, is then raised to its normal position.

The pad may also be depressed by the rider's weight acting on

The lever or rod or equivalent brake-operating device may be provided with
means for adjusting its length or position to suit the height or position of the
saddle.
The pad or other device may be formed upon or hinged or otherwise connected
to the saddle in any convenient manner, or it may be entirely disconnected there-

may be made removeable from the said saddle.

I may apply my invention to the operation of the brake of the front wheel
of a bicycle as also to the operation of the brakes of tricycles or other velocipedes.

I, The Right Honourable Sir JOHN DOUGLAS SUTHERLAND CAMPBELL,
commonly called the Marquis of Lorne, K.T., of Kensington Palace, in the County
of London, 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 brakes for velocipedes, and has for its object to provide
means whereby the weight of the rider is directly employed in controlling the
brake. According to my invention I provide in connection with. or in proximity
to the saddle of the velocipede a pad, or pads, or the like, which is, or are, con-
nected with the brake in such a manner that the weight of the rider can operate
upon the said pad, or pads, or the like, to control the brake.
In Figure 1 of the accompanying drawings I have shewn, in side elevation,
means whereby my invention may be carried into effect. A is the saddle, B part
of the rear wheel, and C, part of the frame of a bicycle, to which my invention
is applied. Figure 2 is a back elevation of the brake mechanism and Figures 3
and 4 shew in plan the two supports by which the brake rod is supported. I have
shewn the parts as being adjustable in length, but the arrangements for this
adjustment may be dispensed with. On the pin d connecting the saddle post
with the back fork are links e carrying a pin on which turns an eye in the end
of a hollow rod f into which passes one end of a rod g secured therein by the
screw. The other end of the rod g carries an eye piece g² to which the tubular
rod h is connected this rod h receiving at one end a rod i with a cradle at top
carrying a pad I secured therein by a screw passing longitudinally through it.
The rod is adjustable in the hollow rod and is fixed therein by the screw g
The rod h passes through an eye in the end of a rod j fixed by a screw k³
in a socket k carried by arms secured to the back-fork by straps . The
lower end of the rod h has secured to it the brake shoe L. The spring h² is con-
fined between the collar h³ on the rod h and the eye j³. When the brake is to
be applied the rider moves back so as to press upon the pad I and force down
the brake upon the wheel, the spring h² being compressed, the said spring taking
off the brake when the rider's weight is removed from the pad I. I do not
limit myself to the precise details shown in the drawing as variations may be
made without departing from the nature of my invention, for example, the pad
may be attached to the saddle by a spring and the brake be connected thereto
so that, when the pad is depressed, the spring yields and the brake is applied,
or the brake may be normally applied by a spring and taken off by the weight of
the rider on the pad so that by removing the weight of the rider from the pad
the brake is applied.
The connection between the pad and the brake may be by means of bell crank-
levers instead of directly as shewn.
Figures 5 and 6 represent the application to a rim brake. The parts in these
figures which correspond to those shewn in Figures 1 and 2 are marked with the
same letters of reference. The rod h is connected to a fork / whose ends are
connected to lever arms m turning on centres secured to the fork of the frame
and carrying the brake shoes L.
The rim can be roughened to give a better grip to the brake.
Instead of a pad, or pads, any other equivalent device upon which the weight
of the rider can be brought may be used.

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:-
In, or for, velocipedes the arrangement and combination of parts constituting
a brake and means for operating it substantially as hereinbefore described whether
applied to a tyre brake as illustrated in Figures 1 to 4 or to a rim brake as in
Figures 5 and 6.
