Improvements in Cycles.
1, BERNARD LEFEBURE, of 5 St. Mary Axe, in the City of London, Engineer,
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:-
My invention has reference to the adaptation and combination of key locks or
letter locks with the frames and steering spindles of cycles in such wise as to enable
the steering spindles to be locked or fastened as hereinafter set forth with reference
to the accompanying illustrative drawings whereof
Fig. 1 shows a combination and arrangement of parts according to my invention,
A being a part of the frame of the machine and B a part of the steering spindle,
which is represented as being fitted with lugs C and a transverse bolt or screw D;
E is the bolt of a lock and is adapted to enter between the lugs C and when there
to prevent the steering spindle from being turned so as to steer the machine, which
however might still be pushed along. To prevent this also the steering spindle B
may be turned to such a degree as to bring the bolt E on either side of the lugs C,
thus rendering it practically impossible to move the machine without lifting it.
The bolt E. which slides in the casing F of the lock is at one end provided with a
knob J or a ring or convenient equivalent whereby to move the holt by hand. In
the bolt E there are shewn two notches or recesses into either of which can enter a
part of the tumbler or latch G (or there might be more than one tumbler or latch).
When the bolt E is pushed towards the steering spindle B the tumbler G enters
the second notch whence it can be moved by means of an appropriate key. Under
the tumbler G (or each tumbler) is a spring to keep it in place. This arrangement
for securing the bolt E and releasing it by means of a key is shown by way of
example, but other key lock mechanism may be employed in carrying out my
invention. H is a screw or pin in the lock and there is as shewn by dotted lines a
slot in the bolt E, which is thus prevented from being pulled out. The bolt E is
shown fitting under and above the screw or bolt D, but this is not absolutely
necessary as in most cases it will suffice for the bolt E to extend to either the top
or bottom of the bolt or screw D. The casing F is provided with flanges I and is
fastened to the cycle frame A by screws, rivets, bolts or clips, and can be also
brazed to it. This casing F can be made with loose sides or top to facilitate
putting the lock together. In place of the lugs C and bolt D a bracket, collar
bracket or segment can be fastened to the steering spindle B.
Fig. 2 shows a combination and arrangement of parts in a similar cycle A being
the frame B the steering spindle, C the lugs and D the screw or bolt as before.
The bolt E fits in a frame or bracket F in which is fitted a pin or screw H to
prevent bolt E being pulled out or the bolt E may be provided with shoulders as
shown in Figs. 3 and 4. Under, above or on either side of the bolt E is a bar K
provided with a key or projection 'K', as shown in section in Fig. 5 and in which
there are notches. This bar K fits and is able to slide in a bush L, which is
fastened to the bracket F. In the bush L aud also in the frame F there is a slot
to allow the projection on K to pass through. On the bush L there are discs M.
(or there might be only one) which for a part of their length or thickness are
formed with recesses to allow the bush L to turn when the projections on K are in
such recesses. The discs M are marked with letters or figures. The bar K is
fastened to a plate N, to which the bolt E is also fastened so that K and E must

page_text: always move together. The key or projection of K can be of such a length as to
allow of or prevent the discs M being turned when the lock is unfastened.
Figs. 6 and 7 show another arrangement. In this case there are disce M shown
on three sides of the casing F. The pins H are placed in the bolt E and fit in
recesses of the discs O, which are rivetted or secured to the discs M. Fig. 8
shows another arrangement there being in this case several discs placed in a single
row. Figs. 9 and 10 show discs O in plan. In Fig. 9 the disc is plain with a slot
in it for part of its diameter, and the arrangement is such that the discs O and M
cannot be turned round when the pins H are in the slots. The disc O shown in
Fig. 10 has a recess in a part of it and in the remaining portion has a slot for the
pin H. In this case O and M. can be turned when the lock is unfastened.
Fig. 11 shows a combination and arrangement of parts wherein the lock case F
is fastened to a part of the frame A that is co-axial with the steering spindle B and
Fig. 12 shows another arrangement the casing F of the lock being in this case
fastened to the steering spindle B. In both these arrangements which will be
understood from the drawings, instead of providing a separate bar K as in Fig. 2.
a part K¹ of the bolt E is made to serve as a substitute for bar K, and passes the
bush L on which are arranged discs M as in Fig. 2.
In Fig. 12 a collar P is shown which forms part of or is fastened to the frame A.
Such a collar P can also be used when the bolt E is arranged at any angle with
the steering spindle B; the collar is provided with holes, projections or notches to
suit the bolt E, which may be of any section. If necessary a spring can be placed
between the casing F and the knob J, to prevent vibration. Some cycles have
their steering spindles B fitted with one or more nuts and these can be used instead
of a collar such as P and the locks can then be placed as shown in Figs. 1, 2, 6, 8
or .11.
Fig. 13 shows an arrangement in which a lock whose casing F is fastened to the
cycle frame A, is constructed with a bolt that passes through the frame which is
provided with an opening for the purpose and on the steering spindle B within the
hollow frame A is a collar P with notches or recesses to receive the end of bolt E;
or the bolt E can be made to pass through the steering spindle B or the latter can
be fitted with a collar P as described with reference to Fig. 12.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
1. The combination with the frame and the steering spindle of a cycle, of a lock
permanently attached to one of said parts and constructed with a sliding bolt
adapted to engage with or hold the other of said parts so as to prevent turning of
the steering spindle when locked, substantially as described.
2. In a cycle the combination with the frame and the steering spindle of a key
lock or a letter lock so constructed and arranged as to enable the steering spindle
to be locked and unlocked without the use of a removable pin substantially as
hereinabove described with reference to the several examples illustrated in the
accompanying illustrative drawings.
Dated this 18th day of March 1896.
