page_text: Improvements in Safety Locks for Velocipedes.
I, MASSIMILIANO BADONI, of Rue de Lancy 14, Geneva, in the Republic of
Switzerland, Mechanician, do hereby declare the nature of this invention to be
as follows:
The present invention relates to a safety lock and is intended when desired
to prevent the use of velocipedes by any person except the one in possession
of the key.
The improved safety-lock is adapted to be applied to the frame of any veloci-
pede in such a manner that its bolt will not be in the way while the machine is
in use and so that the said bolt or lock may be passed between the spokes of
the wheel of the velocipede when the latter is to be locked.
To one of the branches of the forked portion of the frame between which is
arranged the wheel to be locked, there is fixed, by means of a band or staple, a
bracket carrying the lock with its bolt and to the other branch of the said forked
portion of the frame there is fixed, by means of a band or staple a bracket
carrying the loop or catch. The bands or staples are fixed to the frame by means
of screw-bolts the nuts of which are sunk in a depression of the brackets and
said screw-nuts can only be acted upon by means of a key, when the lock is
open, that is to say, when the bolt of the same is in its open position, for, when
it is shut, these screw-nuts are covered by the said bolt.
To the bracket there is fixed, by means of a pivot, a box into which the bolt
slides longitudinally. If the box is oscillated on its pivot, fixed on that part of
the frame and if the bolt is at same time slid into this box, the said bolt can
be brought from the position in line with the member of the fork on which it is
secured in which it does not prevent the rotation of the wheel, to the position
transverse to or across the fork in which it prevents the rotation of the said
wheel by passing between the spokes and engaging into the loop fixed to the
opposite part of the frame.
The oscillation of the box on its pivot is limited by an abutment projecting
from the bracket and the sliding of the bolt in the box is limited on the one
side by the hooked end which is intended to engage a second projection of the
bracket, and on the other side by a screw fixed to the said bolt. The hook of the
bolt has a notch which engages the projection of the bracket when the lock is
placed out of use. In the box there is provided a plate having a certain number
of pins each acted upon by a spring which tends to maintain them projecting

page_text: over the face of the said plate over which the bolt is slid. The latter is provided
with a certain number of holes the relative position of which corresponds with
the relative position of the pins and into which the latter engage when the bolt
is slid into its locking position.
The key intended to open the lock by disengaging the pins from the bolt is
provided with screws the relative position of which exactly corresponds with that
of the holes and of the pins in the box. The key is smaller than the bolt in
order to engage into that portion of the box situated above the shoulder serving
as a guide for the bolt. A spring lodged in the upper portion of the box and
which is stronger than all the springs together, presses the key against the bolt
when engaged into the said portion of the box and consequently the said spring
causes the screws of said key to drive back the pins from the holes of the bolt
as soon as the key arrives in the desired position as to cause its screws to be
placed in front of the pins of the box. The bolt may now again be moved
longitudinally into the box the key moving with the said bolt.
This form of safety-lock offers the great advantage of being adapted to be
made in a large number of varieties as to its key, without any of the keys being
able to be used in place of any other, even if the screws be only situated a very
small distance apart with respect to any other similar key.
A cover hinged to the bolt allows the box to be shut when the lock is not
in use.

I, MASSIMILIANO BADONI, of Rue de Lancy 14, Geneva, in the Republic of
Switzerland, Mechanician, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
-
The present invention relates to a safety lock and is intended when desired
to prevent the use of velocipedes, by any person except the one in possession
of the key.
The improved safety-lock is adapted to be applied to the frame of any veloci-
pede, in such a manner that its bolt will not be in the way while the machine is
in use and so that the said bolt or lock may be passed between the spokes of
the wheel of the velocipede when the latter is to be locked.
The accompanying drawing illustrates by way of example one form of execu-
tion of the invention. In the said drawing:
Figure 1 is a front elevation of one portion of the frame of a velocipede pro-
vided with the invention the lock being open.
Figure 2 is a similar elevation, the lock being shut.
Figure 3 is a longitudinal section of one portion of the lock, its bolt being
open.
Figure 4 is a longitudinal section of one portion of the lock, its bolt being
shut.
Figure 5 is a transverse section of the lock.
Figure 6 illustrates separately the bolt of the lock.

page_text: Figure 7 illustrates one detached portion of the lock shown from the top,
from below and in side-elevation.
Figure 8 shows a perspective-view of the tool for turning the screws fastening
the lock to the frame of the machine.
Figure 9 is a perspective view of the key, hereinafter referred to.
In all the figures similar letters refer to the same parts.
A A¹ is a forked portion of that part of the frame of the machine between
which is arranged the wheel to be locked. To one of the branches A of the said
forked portion of the frame there is fixed, by means of a band or staple Ba
bracket C carrying the lock with its bolt D and to the other branch A₁ of the
said forked portion of the frame there is fixed, by means of a band or staple E
a bracket carrying the loop or catch FI. The bands or staples B and E are
fixed to the frame by means of screw-bolts 6 and e, the nuts of which are sunk
in a depression of the brackets C and F and said screw-nuts can only be acted.
upon by means of the key G, (Figure 9), when the lock is open, (Figure 1) that
is to say, when the bolt of the same is in its open position as in Figure 3, for,
when it is shut (Figure 2) these screw-nuts are covered by the said bolt 1).
To the bracket C there is fixed, by means of a pivot e a box H into which
the bolt D slides longitudinally. If the box H is oscillated on its pivot c, fixed
on that part A of the frame and if the bolt D is at the same time slid into this
box, the said bolt can be brought from the position in line with the member of
the fork on which it is secured, as shown in Figure 1 in which it does not prevent
the rotation of the wheel to the position transverse to or across the fork as shown
in Figure 2, in which it prevents the rotation of the said wheel by passing
between the spokes and engaging into the loop F fixed to the portion A' of
the frame.
The oscillation of the box H on its pivot c is limited by an abutment c¹, and
the sliding of the bolt D in the box H is limited on one side by the hooked end d
of said bolt D and on the other side by means of a screw d¹.
The hooked end has an outeut d² which is intended to engage the projection
of the bracket C when the lock is in the position shown in Figure 1.
In the box H there is provided a plate J (Figure 7) having a certain number
of pins K K K³ each acted upon by a spring k which tends to maintain them
projecting over the face of the said plate J over which the bolt D is slid. The
latter is provided with a certain number of holes L' L2 L3 the relative position
of which corresponds with the relative position of the pins K' K K and into
which the latter engage when the bolt D is slid into its locking position (Figures 4
and 5).
The key M (Figure 8) intended to open the lock by disengaging the
pins K K K from the bolt D is provided with screws m¹ m² m³ the relative
position of which exactly corresponds with that of the holes L1 L2 L³ and of the
ins K K K The key M is smaller than the bolt D in order to engage into
that portion of the box H situated above the shoulder h serving as a guide for
the bolt. A spring lodged in the upper portion of the box H and which is
stronger than all the springs together, presses the key M against the bolt 1)
when engaged into the said portion of the box H and consequently the said
spring causes the screws m² m² m³ of said key to drive back the pins K' K² K
from the holes L' L2 L3 of the bolt D as soon as the key M arrives in the desired
position as to cause its screws m² m² m³ to be placed in front of the pins K¹ K² K³.
The bolt D may now again be moved longitudinally into the box H as may be
seen in Figure 3, the key M moving with the said bolt D.
This form of safety-lock offers the great advantage of being adapted to be
made in a large number of varieties as to its key, without any of the keys being
able to be used in place of any other, even if the screws m¹ m² m³ be only situated
a very small distance apart with respect to any other similar key.
A cover H¹ hinged to the bolt D allows the box H to be shut when the lock is
not in use,

page_text: 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: —
1. In a lock for cycles, the combination with a part of the frame, within which
the driving-wheel turns, of a clip secured to the frame at one side of the driving-
wheel, a guide-box pivoted to the clip, a longitudinally movable bolt and means
at the other side of the frame wherewith the outer end of said bolt is adapted
to cooperate for preventing the turning of the driving-wheel, substantially as
set forth..
2. In a lock for cycles, the combination with a clip adapted to be secured to
the frame of the cycle, of a guide-box pivoted to the said clip, a sliding bolt in
said box for engaging said bolt for locking the same in operative position, sub-
stantially as set forth.
3. In a lock for cycles, the combination with a clip adapted to be secured to
the frame of the cycle, of a guide-box pivoted to said clip, said guide-box being
provided with a laterally extending projection, and abutments on said box
adapted to strike said projection, a sliding bolt guided, in said box and locking
devices in said box for engaging said bolt and for locking the same in transverse
position, substantially as set forth.
4. In locks for cycles, the combination with a clip adapted to be secured to
the frame of the cycle, of a guide-box pivoted to said clip, a plate in said box
provided with a series of holes, spring-actuated pins guided in said holes, and a
sliding bolt in said box provided with holes also engaged by said pins for locking
the said bolt in transverse position, substantially as set forth.
