A New or Improved Brake for Cycles and the like.
I HENRY GRANT HOGG of 18 Endsleigh Street, Tavistock Square, London W.C.
Watchmaker do hereby declare the nature of this invention to be as follows:-
This invention relates to a new or improved brake for tyres the object being to
apply the brake to the outer periphery of the wheel but at the same time to obviate
the tearing or rapid wearing away of pneumatic or india rubber tyres by or
consequent upon the brake action when applied as ordinarily to the tyre.
In constructing and applying my improved brake I apply to the brake lever rod
a cross bar carrying arms or hangers and the ends of these cross arms or hangers
are formed as bearings in which are mounted or set pins, studs, or centres upon
which semi spheres or half balls are mounted and these (the semispheres) serve as
centres for a double cup ended roller which works in such wise and in relation to
the tyre that when the brake lever is depressed the said semispheres will come into
contact with the tyre of the wheel and effect such pressure thereon as will serve
effectually as a brake but will not tear or unduly wear upon the tyre.

I HENRY GRANT HOGG of 18 Endsleigh Street, Tavistock Square, London, W.C.
Watchmaker 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:-
This invention relates to a new or improved brake for tyres the object being to
apply the brake to the outer periphery of the wheel. but at the same time to obviate
the tearing or rapid wearing away of pneumatic or india-rubber tyres by or consequent
upon the brake action when applied as ordinarily to the tyre.
In constructing and applying my improved brake I apply to the brake lever rod a
cross bar carrying arms or hangers and the ends of these cross arms or hangers are
formed as bearings in which are mounted or set, pins, studs or centres, upon which
semi-spheres or half balls are mounted and these (the semi-spheres) serve as centres
for a double cup-ended roller which works in such wise and in relation to the tyre
that when the brake lever is depressed external surface of the said semi-spherical ends
of the roller or their covering will come into contact with the tyre of the wheel and
effect such pressure thereon as will serve effectually as a brake but will not tear or
unduly wear upon the tyre.
In order that the said invention may be well understood there is annexed

page_text: hereto a sheet of drawings illustrative thereof which will be referred to by figures
and letters in the following more particular description, like letters referring to
similar parts.
Fig. 1. is an elevational view of the brake rod and frame, and rubber covered roller
the latter being in section and Fig. 2. is an end view of Fig. 1. Fig. 3 is similar
view but with part of the roller and frame broken away and showing a modification of
the form of the roller and the application of a dust cover to the end of the brake
roller.
Fig. 4 is an end view of the roller and dust cover shown in Fig. 3 the cover being
partially broken away.
A is the brake rod which will be fitted with recovery spring, and be connected with
the brake lever for depressing the same as and when the brake roller is applied to the
tyre of the wheel substantially as ordinarily. The brake rod A, is attached to the
cross bar and arms a; b, is a cross pin or axle, the ends of said axle being screw
threaded for reception of holding nuts and rounded at the neck where it passes
through the arms a. Intermediately of this axle it is squared at a' so as to fit square
holes in the semi-spheres c, said semispheres e serving as centres for a double cup-
ended roller d. The cup-ended roller d shown in Figs. 1 and 3 are slightly
different in design of the external contour at the ends and are covered with india-
.rubber as shown at e.
In Figs. 3 and 4, findicates a dust cap which consists of a centrally pierced disc
with a turned up continuous flange thereon, the rim of said flange being entered into
a circular groove of the roller d.
In fitting the roller d, and the centres c, in the arms a, the said centres are to be
placed in the concavities at the end of the roller d, and the same be placed between
the arms a so that the axle may be passed through from one side to the other where-
upon the screw nuts on the end of the axle will be tightened up against the arms a,
and the sphere centres c, will be retained fast on the squared middle portion a¹ of the
axle and the roller d, e, will be free to turn.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The new or improved brake for cycles and the like as and for the purpose herein
et forth.
