"Engineer" do hereby declare the nature of this invention to be as follows:-
This Invention refers to improvements in brakes applicable to cycles, motorcars
velocipedes and other similar vehicles the object being to produce a simple and
efficient brake which shall be free from the common defect of cutting and damaging
the tyres of machines.
It is a well known law of mechanics that, friction does not increase with the extent
of rubbing surface (other things being equal) but varies with the pressure, advantage
is taken of this fact to obtain a rolling contact between the wheel and a revolving
endless or continuous band or belt of suitable material, and a rubbing or brakeing
contact, between the endless or continuous band or belt and a cylinder, drum, wheel,
barrel, or block of suitable material and shape which said cylinder or block is fixed
between the frane or carrier of the brake in such a way that it is prevented from
revolving with the endless or continuous band, to illustrate the action of such a brake
I will describe the one I have experimented with (it being understood I do not bind
myself strictly to these sizes or materials) the barrel or block is a steel tube 1" in
diameter and 1" long fastened between the forked end of the brake frame or
carrier in such a way that it cannot revolve, on this tube is mounted loosely an
indiarubber band or ring thick, 1" broad consequently 1" outside diameter
when the brake is used the endless band is brought in contact with the wheel of
machine and the band is pinched between the tyre and barrel the pressure inside and
out being equal irrespective of surface in contact, and whether lightly or heavily
applied and as the distance from centre of barrel to outside of band is greater than to
inner side of band it is compelled to move and so roll on the tyre or wheel and rub on
the block as the angular velocity of endless band in contact with tyre is greater than
that in contact with the steel tube so much as to make the movement of the band
certain.

HENRY SHAW MOORE Station Road Beighton near Sheffield, Yorkshire, Engineer
do hereby declare the nature of this invention and in what manner the same is to be

page_text: performed, to be particularly described and ascertained in and by the following
statement
This Invention refers to improvements in Brakes applicable to Cycles, Motorcars
and other similar vehicles the object being to produce a simple and efficient brake
which shall be free from the common defect of cutting and damaging the tyres of
machines it is well known that friction does not increase with increase of rubbing
surface (other things being equal) but varies according to the pressure applied it
being understood to be Pressure X Distance X coefficient of friction advantage is
taken of this fact to obtain a rolling contact between the cycle wheel and an endless
or continuous band or bolt of suitable material and a rubbing or
braking contact
between the endless or continuous band or belt and a cylinder, drum, barrel or block
of suitable material and shape which said cylinder drun barrel or block is fixed
between the forked ends of the brake frame or carrier in such a way that it cannot
revolve with the endless band; in carrying out this Invention the brake frame or
carrier is brazed to the bottom of the ordinary brake tube and the endless or
continuous band or belt is placed on the block and both placed between the sides of
the carrier a bolt is passed through the lot which thus binds the brake block and
carrier together but leaves the endless band free to revolve the action is as follows on
applying the brake the endless band or belt comes in contact with the wheel or tyre
or machine and is pinched between the tyre and Brake Block the pressure inside and
outside the band being the same however heavily applied and as the distance from
centre of brake block to outside of band is greater than to inside of band the band revolves
by virtue of the greater leverage rolling on the tyre and rubbing on the fixed block
the materials used may be any kind suitable for the purpose various combinations of
Brass Steel Hardwood Vulcanised fibre Indiarubber and Canvas having been tried the
best results have so far obtained with a Steel frame or carrier a Brass Brake Block and
an Indiarubber and Canvas Band or belt corrugated on the outside as shown. The
accompanying drawings illustrate my Invention Fig. 1 is vertical and horizontal
sections of the various parts A and A¹ showing fraine or carrier Band B' showing
Brake Block Cand C showing Endless or Continuous band or belt Fig 2 is a horizontal
section of the parts A B C assembled in position and showing the bolt 1 for holding
them in position Fig 3 is a vertical section of the parts A B CD assembled in position
showing part of brake tube E for brazing to.
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 an Endless or Continuous Band or Belt of suitable material loosely mounted
on a fixed Brake Cylinder or Block.
Secondly a Brake Cylinder or Block of suitable material fixed in brake frame or
carrier.
Thirdly the combination of a brake frame, a fixed Brake Block, and an Endless or
Continuous Band or Belt as herein before specified and described and as illustrated by
the accompanying drawings.
