page_text: I, HENRI BRISSELET, of 17, Rue du Cendrier, Geneva, in the Republic of Swit-
zerland, Mechanician, do hereby declare the nature of this invention to be as
follows:-
The invention consists of a combination of means for constructing in a cheap
and easy manner a safety-lock and its key.
One portion of the improved lock forms the matrix or bottom-die, by means of
which the special form and configuration of the key and of a second portion of
the lock is obtained by stainping, the manufacture of similar keys being there-
fore rendered impossible when the lock is finished without taking the said lock
to pieces.
The portion of the lock which, as explained above is used as a matrix or
bottom-die for stamping the corresponding key, is provided with one or more
suitable straight lined notches or grooves, which, if there are more than one,
must be parallel to one another. The said notches or grooves may be made of
any suitable section whatever so as not to be easily imitated, such notches or grooves
being made in the said piece of the lock by means of any suitable tool, for
instance by means of suitable grinding wheels, and so as to be quite different
in each case, that is to say in each of said pieces of different locks.
The said notches or grooves may differ by the shape or configuration of their
section, by the distance between two adjacent notches or grooves, the depth of
the same and so on, and all these differences will be exactly reproduced in the
key and the second portion of the lock and no key will act upon the lock in
question if it does not reproduce exactly the said notches or grooves.
The above mentioned two portions of the lock which are provided with cor-
responding notches or grooves are fixed in the said lock in such a position with
regard to each other, that the corresponding key may be slid with smooth fric-
tion between the same, the said key being preferably made of thin sheet metal
so that the space between the said two notched portions of the lock will be so
small as to prevent the introduction between the same of any tool or wire for
the purpose of opening the lock without the corresponding key.
The said notched portions of the lock and correspondingly notched key aro
combined with a spring or spring-bolt located within the lock and intended to
lock the same in any well known manner and to be unlocked by the mere intro-
duction of the key between the two notched portions of the lock. One of the
said two notched portions of the lock may in some instances be fixed to the
lock and the other one be formed or fixed on the bolt of the lock or they may
be formed or fixed both to the lock or both to the bolt, their respective posi-
tion in the said lock being in any case exactly predetermined by the casing of
the latter, so as to insure the working of the key in the above described manner.

I, HENRI BRISSELET, of 17, Rue du Cendrier," Geneva, in the Republic of Swit-
zerland, Mechanician, 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 :-
The invention relates to a combination of means for constructing in a cheap
and easy manner a' safety-lock and its key.
One portion of the improved lock forms the matrix or bottom-die, by means of
which the special form and configuration of the key and of a second portion of
the lock is obtained by stamping, the manufacture of similar keys being there-
fore rendered impossible when the lock is finished without taking the said lock
to pieces.
The portion of the lock which, as explained above is used as a matrix or
bottom-die for stamping the corresponding key is provided with one or more
suitable straight lined notches or grooves which, if there are more than one,
must be parallel to one another. The said notches or grooves may be made of
any suitable section so as not to be easily imitated, such notches or grooves
being made in the said piece of the lock by means of any suitable tool, for
instance by means of suitable grinding wheels, and so as to be quite different
in each case, that is to say in each of said pieces of different locks.
The said notches or grooves may differ in the shape or configuration of their
section, by the distance between two adjacent notches or grooves, the depth of
the same and so on, and all these differences will be exactly reproduced in the
key and the second portion of the lock and no key will act upon the lock in
question, if it is not provided with exactly the same notches or grooves.
The above mentioned two portions of the lock which are provided with cor-
responding notches or grooves are fixed in the said lock in such a position with
regard to each other, that the corresponding key may be slid with smooth fric-
tion between the same, the said key being preferably made of thin sheet metal
so that the space between the said two notched portions of the lock will be so
small as to prevent the introduction between the same of any tool or wire for
the purpose of opening the lock without the corresponding key.
The said notched portions of the lock and correspondingly notched key are
combined with a spring or spring-bolt located within the lock and intended to
lock the same in any well known manner and to be unlocked by the mere intro-
duction of the key between the two notched portions of the lock.
said two notched portions of the lock may in some instances be fixed to the
One of the
lock and the other one be formed or fixed on the bolt of the lock or they may
be formed or fixed both to the lock or both to the bolt, their respective posi-
tions in the said lock being in any case exactly predetermined by the casing of
the latter, so as to insure the working of the key in the above described manner.
The accompanying drawings illustrate by way of example a method of carry-
ing out the said invention.
The improved lock is supposed in this case to be intended to lock the wheel
of a bicycle by means of a chain to the frame of the same, when the machine is
to be left stationary.
In the drawings Figure 1 is a view of the lock and chain when locked.

page_text: Figure 18 a pian-view of the lock the casing being shown in longitudinal
section.
Figure 3 is a plan-view of the corresponding key.
Figure 4 is a side-elevation of the same.
Figure 5 is a longitudinal section on line X-Y of Figure 1.
Figure 6 is a cross-section on the line Y-Z of Figure 5.
Figure 7 is a section of the lock similar to Figure 5 but with the key shown
in its unlocking position.
Figure 8 is a section through the line U-V of Figure 7.
Figure 9 is a section of the lock similar to Figure 5 after the withdrawal of
the bolt 3.
Figure 10 is a sectional view of the bolt shewn separately.
In all the figures of the drawings, like letters of reference indicate similar
parts.
The improved lock is composed of a casing made of two portions 7 and 8
firmly fixed to one another by means of rivets, solder or by any other suitable
means, of a bolt 3 intended to be locked in the said casing by means of a spring
and of a key 2 intended to disengage the said spring 6 from the bolt 3 when
the lock is to be opened. The said spring 6 is longitudinally divided into a
number of spring fingers.
The chain 9 has one of its ends firmly connected to the casing of the lock
(Figures 1, 2 and 5) and its other end firmly connected to the bolt 3 (Figures 1,
5 and 7).
In the lock shown in the accompanying drawings the bolt 3 is that part of
the invention which has been hereinbefore called the first portion of the lock,
which has been used as a matrix or bottom-die, and the portion of the casing 7
which is marked 1 in the drawings is what has been called the second portion
of the lock, the form of which has been obtained by stamping the said portion 1
together with the key 2, formed of sheet metal into the matrix 3 as shown in
Figure 8.
The longitudinal grooves 4 of the bolt 3 are made of any irregular or regular
shape to which the key 2 and the portion 1 of the casing of the lock exactly
correspond having been stamped with one another. The portions 7 and 8 of the
casing are fixed to one another in such a position that the bolt 3 and key 2 may
exactly fit and slide between them as shown in Figures 7 and 8.
The bolt 3 is further provided with a transverse notch or groove 10 (Figures 5,
7 and 10) into which engages the end of a spring 6 fixed to the casing of the
lock, as shown in Figures 5, 6 and 7, whenever the said bolt 3 is locked in the
said casing.
If the key 2 is inserted in the space 5 between the said bolt 3 and the notched
portion 1 of the casing of the lock as shown in Figure 7, the ends of the spring 6
are forced out of the notch or groove 10 and the bolt 3 can be removed from
the lock as shown in the Figures 9 and 10. It is to be well understood that I
do not limit myself to the precise details of construction of the lock shown and
described but may make such modifications as may fall within the scope of my
invention.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what
I claim is;-
A method of making safety-locks consisting in forming a portion of hard
netal, provided with one or more suitable straightlined notches or grooves of any
uitable section and forming by stamping on the said portion as a matrix or
ottom-die a key of thin sheet-metal and a second portion of the lock, the said
ey and the second portion of the lock having thus exactly the form and con-
iguration corresponding to the special form or configuration of the first portion
f the lock and then uniting the said two portions of the lock which are pro-

page_text: vided with notches or grooves in such a position with regard to each other that
the corresponding key may be slid with smooth friction between the same in
view of acting upon any suitable spring or spring-bolt with which the said lock
is provided.
