AN IMPROVED STOP-BELL FOR VELOCIPEDES
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I FREDERICK WARNER JONES of No. 170 Sidwell Street, Exoter in the County
of Devonshire, Engineer, do hereby declare the nature of my said invention for
AN IMPROVED STOP-BELL FOR VELOCIPEDES, to be as follows:-
My improved stop-bell is suitable for any kind of Velocipede, & though the
principle of its construction remains the saine the method of mounting it must of
necessity vary with cach particular class of machine to which it is fitted; I will
therefore describe it as fitted to an ordinary Bicycle, in which case it is fitted to
the handle bar and is constructed as follows:-Fixed to the handle bar by any
approved method is a small bracket to which is jointed by a knuckle joint, a short
arm carrying at its extremity an ordinary spherical bell. This knuckle jointed
lever is mounted to the bracket on the handle bar, so that it may either stand out
at right angles to the handle bar, or lie parallel to it, for a purpose that will
presently be made clear. A suitable spring is provided to keep the arm steady in
both.positions.
The clapper of the bell is connected by a light chain, metallic cord or other
suitable material, or by a combination of a light rod & a chain or cord, to the
bracket fixed to the handle bar, at such a position so that when the knuckle
jointed arm is at right angles to the handle bar, the distance between the bell
& the point of connection with the bracket is greater than when the knuckle
jointed arm lies parallel with the handle bar; therefore when the knuckle jointed
arm stands out at right angles to the handle bar, the connecting medium between
the bracket & the clapper is slack, & the bell is free to ring; but when the knuckle
jointed arm is set parallel to the handle bar the connecting medium between the
bracket & the clapper is taut, the clapper being pulled up tight against the interior
of the bell, and so silencing it.

page_text: I FREDERICK WARNER JONES of No 170 Sidwell Street, Exeter, in the County
of Devonshire, Engineer, do bereby declare the nature of my said invention for
"AN IMPROVED STOP-BELL FOR VELOCIPEDES" and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:
My improved stop-bell is suitable for any kind of Velocipede and though the
principle of its construction remains the same the method of mounting it must of
necessity vary with each particular class of machine to which it is fitted. I will
therefore describe it as fitted to an ordinary Bicycle in which case it is fitted to
the handle bar and is constructed as follows:-Fixed to the handle bar by any
approved method is a small bracket to which is jointed by a knuckle joint, a short
arm carrying at its extremity an ordinary spherical bell. This knuckle jointed
lever is mounted to the bracket on the handle bar, so that it may either stand out
át right angles to the bar or be parallel to it, for a purpose that will presently be
made clear. A suitable spring is provided to keep the arm steady in both
positions.
The clapper of the bell is connected by a light chain, metallic cord, or other
suitable material, or by a combination of a light rod, and a chain, or cord, to the
bracket fixed to the handle bar in such a position that when the knuckle jointed
arm carrying the bell stands out at right angles to the handle bar, the connecting
medium between the clapper and the bracket is slack and the bell is free to ring,
but when the arm is set parallel to the handle bar the connecting medium is taut,
and the clapper being pulled up tight against the interior of the bell, silences it.
In fitting this bell to Tricycles it is sometimes found more convenient for the
bell to ring when the knuckle jointed arm lies parallel to the handle bar and to be
silent when it stands at right angles to it, in this case the connecting medium is
attached to the bracket in such a position that the distance between it and the
bell increases when the arm stands at right angles to the handle bar, and diminishes
when it lies parallel with it.
In order that my invention may be fully understood I will more particularly
describe it with the aid of the accompanying drawing in which similar parts are
denoted by like letters of reference.
In the accompanying drawing which shows the bell as applied to a tricycle
Fig. 1 is a plan showing its position when silent. Fig 2 is a plan showing its
position when ringing. Fig 3 is a side elevation and Fig 4 a front elevation, of
the bell in its silent position. A is the bracket fixed to the handle bar. B is the
C is the bell
the knuckle jointed arm pivotted to the bracket A by the pin x.
fixed at the end of the arin B. D is a spring connected to the bracket A. and the
arm B by small studs a and b. The clapper c of the bell is connected to the
bracket A at the point a' by a chain or cord E. It will be seen that the distanco
between the point a¹ of the bracket A and the bell C is greater when the arm
carrying the bell is parallel with the handle bar, than when it is at right angles to
it, consequently the bell is silent in the former position and ringing in the latter,
but if the position of the point a¹ be reversed and placed on the other side of the
bracket A, ie., on that side to which the arm carrying the bell folds, the distanco
between the point a¹ and the bell will be greatest when the arm carrying the bell
is at right angles to the handle bar and therefore the bell will be silent in that
position, and will ring when it is folded back against the handle bar.

page_text: I do not bind myself to any particular form or shape of bell as it will be obvious
that the shape or form is immaterial, to the principle of my invention.
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
First-The construction of a boll substantially as and for the purpose herein-
before described and shown,
Secondly-Mounting a bell on a knuckle jointed arm pivotted to a bracket as
and for the purpose described and shown.
Thirdly-Connecting the clapper of a bell to a bracket by which the bell is
connected to the machine, so that by varying the position of the bell with
respect to the bracket the bell may be set ringing, or be silenced, as
herein before described and shown.
