I, HERMANN ADOLPHUS REINHOLD of 7, Wellington Street, Woolwich,
London, S.E., Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to brakes, and is especially applicable to pneumatic-tyred
velocipedes.
It consists of an adjustable arrangement which can be readily attached
to any machine. It is so constructed, that the lever now in use in all other brakes
may be entirely dispensed with, and at the same time will also by simple yet
effective means automatically remain fixed in any position, until released by a
simple touch, which is a great boon as it relieves the rider of the continual strain
thrown upon the hand when going down long hills. In conjunction with the above
I employ an easily detachable roller of suitable material, and which runs in metal
bearings, in place of the usual brake-spoon or pad, which are a source of annoyance
to the user on account of the destructive effects exercised upon the tyre as well as
the necessity of frequently renewing the spoon or pad. When my brake is applied
however the roller immediately revolves on coming into contact with the tyre thus
reducing to a minimum the wear of both tyre and roller.
The locking mechanism consists of a detachable lug which is attached to the
handle-bar stem of the cycle, and through which the brake-tube slides. In the
latter are a number of teeth which engage a bolt fitted in the lug at right-angles
to the brake-tube, and actuated by means of a spring. The brake is applied by
merely depressing the brake-tube which is prevented from returning by the afore-
mentioned bolt engaging the teeth on the tube.
I, HERMANN ADOLPHUS REINHOLD, of 7, Wellington Street, Woolwich, in
the County of London, Engineer, do hereby declare the nature of this invention
and in what manner the same is be performed, to be particularly described and
ascertained in and by the following statement :-
My invention relates to brakes, and is especially applicable to pneumatic-tyred
velocipedes. It consists of an adjustable arrangement, which can be readily
attached to any velocipede. It is so constructed that the lever now in use in most
other brakes may be entirely dispensed with, and at the same time will also by
simple yet efficient means automatically remain fixed in any position until released
by a simple touch, which is a great boon, as it relieves the rider of the continual

of being an effective cycle-lock.
In the accompanying drawing,
Fig. I is an elevation of the complete brake as attached to the velocipede.
Fig. Il is a sectional view of the lug b showing details.
Fig. III is a plan of the lug b.
Fig. IV is a front elevation of the brake-fork showing the roller in section.
Referring to Fig. I a is the handle-bar stem of the velocipede to which is
attached the adjustable lug b, and through which the brake-tube slides. The
latter is provided with a-series of-notches of a particular form, c, c' which engage
the bolt d, actuated by the spring e, Fig. II. Now on the brake being applied
which is accomplished by depressing the knob f, Fig. I to the desired extent the
bolt recedes allowing the brake-tube to slide through the lug b, on the pressure
being withdrawn however the tube remains firmly fixed, (owing to the particular
form given to the notches and bolt) until released, which is instantly done by
merely pulling back the trigger g, Fig. III. When the spiral spring h, Fig. I.
immediately forces the tube into its original position.
By putting the brake hard on, and then removing the thumbscrew k, Fig. II the
cycle will be effectively locked, as the trigger will fail to release the brake, thereby
preventing anyone from riding the cycle when left unattended.
In conjunction with the above I employ in place of the usual spoon, or pad a
roller made of rubber or other suitable material.
Running through the centre of this roller is a square hole into which are fitted
at either end two square metal plugs m, m', Fig. IV. about "apart in the centre,
and terminating at either end in the bosses 1, 1, which are countersunk to admit
the centres n, n', between which the roller revolves.
The reason for not having a solid spindle is to maintain a constant. elastic
pressure on the centres, due to the compression of the roller by. those centres, thus
preventing the roller from revolving too freely and thereby detracting from its
efficiency as a brake. The wearing surface being confined solely to the hardened
centres, which may be further adjusted by means of the loose centre, there are no
renewals necessary.
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 :-
(1.) The method of locking the brake substantially as above specified.
(2.) The construction of a roller substantially as above described.
(3.) The manufacture and use of a brake partly or wholly constructed
substantially as hereinbefore described with reference to the accompanying
drawing.
