page_text: I, CHARLES OWEN SLOWE, of The British Hotel, Bangor, North Wales, Hotel
Manager, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in brakes for cycles actuated by means
of one of the handles and has for its object to render such brakes more reliable,
simple and durable than heretofore has been the case.
To this end I employ inside of the handle bar over its stem, a drum, pulley or
chain wheel mounted in suitable bearings. The said drum, pulley or chain wheel
I connect by means of a flexible shaft or short shafts and ball or universal joints
employed inside the handle bar, to one of the said handles which is adapted to be
turned.
The brake rod I employ, suitably guided, in-side the stem of the handle bar
and its socket and place the same under the influence of a spring which has the
tendency of depressing the brake rod.
The upper end of the brake rod I connect by means of a chain band or its
equivalent to the aforesaid drum, pulley or chain wheel and its lower end to a lever
fulcrumed to a plate secured to the said stem socket and adapted to act upon the
tyre when the handle is turned and to be brought out of contact therewith when
the handle is released.
The part of the handle bar opposite the drum or its equivalent I may form with
a cap so as to give access to the same for adjustment and the like purposes.

I, CHARLES OWEN SLOWE, of The British Hotel, Bangor, North Wales, Hotel
Manager, 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 improvements in brakes for cycles actuated by means
of one of the handles and has for its object to render such brakes more reliable,
simple and durable than heretofore has been the case.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with. letters of reference in-
dictating like parts in the various figures, Fig. 1 being a longitudinal section of the
DQ71

page_text: socket supporting the handle bar and Fig. 2 a back view of the same with handle
bar in section, Figs. 3, 5 & 7 are side views, Fig. 4 is a back view, Fig. 6 a plan
and Fig. 8 an end view of some modifications of шу invention.
In carrying out my invention and referring to Figures 1 & 2, I employ inside of
the handle bar a over its stem b, a drum or pulley c mounted in suitable bearings d
secured into the handle bar a at each side of the drum or pulley c. The said drum
or pulley I connect preferably by means of a flexible shaft d'employed inside the
handle bar a, (or by short shafts and ball or universal joints as will be readily
understood), to one of the handles e adapted to be turned.
The brake rod f I employ, suitably guided, inside of the handle bar stem 6 and
its socket h and under the influence of a spring i which has a tendency of
depressing it.
The upper end of the brake rod f I connect by means of an ordinary chain k
and set screw k¹ to the drum or pulley c and its lower end to a little lever or spoon
brake fulcrumed to a plate g secured to the stem socket h. When the handle e is
turned the chain k winds onto the drum or pulley c, thereby lifts the back end of
the lever or spoon brake and brings its front end upon the tyre n whilst when the
handle is released the spring i causes the chain k to unwind and the front end of
the lever or spoon brake to be brought out of contact with the tyre.
The part of the handle bar a opposite to the drum or pulley c I form with a
cap a which can be readily unscrewed so as to give access to the drum or pulley c
and chain for the purpose of adjusting or varying the length of the latter in case of
wear of the brake ? or repairs and to accommodate the height of the handle bar,
which adjustment is effected by the set screw k¹.
In lieu of an ordinary chain, a band k, see Fig. 4, formed with perforations
through which the set screw k¹ is secured into the drum or pulley k may be em-
ployed, or the set screw may be dispensed with and the drum or pulley c formed
with pegs or teeth adapted to engage between the chain links, as shown in Fig. 3.
Another modification consists in fulcruming the lever or spoon brake / to a
split band, as shown in Figs. 5 & 6, which is clipped to the lower end of the
handle bar stem socket h, in lieu of to the plate g secured to the latter.
In order to prevent the handle e turning whilst the brake is not in use I may
secure to the handle bar a adjacent to the inner end of the handle e, a notched
ring o and upon the handle e a spring catch p adapted to engage in one of the
notches of the said ring, which spring catch can be readily depressed by the thumb
and thus the handle released when it is desired to turn it for the purpose of
applying the brake.
.
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:-
In brakes for cycles of the type hereinbefore specified, a chain or the like k in
combination with a lever or spoon brake 7 and a drum or the like c mounted in
the handle bar a, the upper 'end of which chain or the like is adapted to wind upon
the said drum or the like and the latter adapted to be partially rotated by one of the
handles, all substantially as and for the purpose set forth.
