Improvements in Breaks for Velocipedes.
We, WILLIAM HILLMAN, Engineer, and CECIL WILLIAM WHEELER,
Solicitor both of the Sparkbrook Works, Coventry, in the County of Warwick,
do hereby declare the nature of our invention to be as follows:-
The invention relates to an improved construction of break for the wheels of
velocipedes and is applicable more especially to pneumatic tyres.
According to our invention we form at the lower end of the break rol a curved
fork extending over the full width of the tyre and having pins projecting from the
ends thereof on which is mounted a flat flexible piece of india rubber formed with
holes to fit over the pins and placed in position thereon with some amount of
strain applied thereto, such piece of india rubber being held in position on the
pins by means of a bar or by washers rivetted or otherwise fixed on the outer ends
of the pins.
When using a break of the above construction it is lowered as heretofore into
contact with the tyre when according to the break power required it is by further
pressure caused to stretch and fit more or less around the tyre.
The piece of rubber may be strengthened by means of canvas inserted therein
and the pins supporting the same may be extended forward from the fork crown or
backward underneath the same as may be desired.

We, WILLIAM HILLMAN, Engineer, and CECIL WILLIAM WHEELER,
Solicitor, both of the Sparkbrook Works, Coventry, in the County of Warwick,
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:-
:-
The invention relates to an improved construction of break for the wheels of
velocipedes and is applicable more especially to those having pneumatic tyres.
The invention is illustrated in the accompanying drawings, in which:-
Fig. 1 is a front view and Fig. 2 a side view of part of the head and part of the
front fork of a velocipede fitted with our improved break.
Fig. 3 is a plan of the break shown separately.
Figs. 4 and 5 are sectional views of the metal portion of the break taken at right
angles to each other, and Fig. 6 is an underside view of the same.
According to our invention we form at the lower end of break rod a, a curved
fork or forks b extending over the full width of the tyre. This curved fork is

page_text: formed with a curved crown or upper portion b, which may be perforated with a
number of holes 6 as shown, in order to reduce its weight. At the front and rear
of the said curved crown the inetal is bent in a vertical direction to form the
curved forks b, which are formed with holes in each end thereof to receive bolts c,
on which is mounted a flat flexible piece of rubber d formed with holes to fit over
the bolts cand placed in position thereon with some amount of strain applied
thereto, such bolts c being held in position by nuts c¹.
In some cases, instead of employing two curved forks b, we employ a single one
having pins projecting from the ends thereof on which is mounted the flat flexible
piece of rubber d, which, in this case, is held in position by means of a bar or by
washers rivetted or otherwise fixed on the outer ends of the pins.
The piece of rubber d may be strengthened by means of canvas d' inserted
therein, and the pins or bolts supporting the same may extend forward from the
fork crown e, or backward underneath the same as may be desired.
When using a break of the above construction, it is lowered by the break lever,
as heretofore, into contact with the tyre, when, according to the break power
required, it is, by further pressure, caused to stretch and fit more or less around
the tyre,
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. A break for velocipedes consisting of a carrier provided with two pins or
bolts on which is mounted a flat flexible piece of india-rubber which is lowered
into contact with the tyre and fits more or less around the same according to the
pressure exerted.
2. A break for velocipedes constructed substantially as herein shown and
described.
