An Improved Lock.
Year: 1896

page_text: An Improved Lock.
I, SIGMUND LUDWIG GOLDMAN, of 5, Wood Street Square, Wood Street, in
the County of London, Merchant, do hereby declare the nature of this invention
to be as follows:-
This invention relates to an improved lock chiefly designed for use for locking
cycles when left unattended but also applicable for other purposes.
According to my invention I provide a curved bar of metal or other suitable
material, the said bar being preferably somewhat U shaped and to the end of
one of the limbs 1 hinge one end of a second bar the other end of which is
adapted to be locked with the end of the other limb of the curved bar in the usual
manner.
It will be obvious that my improved lock dispenses with the necessity for a chain
when securing a cycle, as the lock itself can be passed through any suitable parts
of the machine so as to lock it.

An Improved Lock.
I, SIGMUND LUDWIG GOLDMAN, formerly of 5, Wood Street Square, Wood
Street, now of 34, Bradford Avenue, Redcross Street, in the County of London,
Merchant, 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 :-
This invention relates to an improved lock chiefly designed for use for locking
cycles when left unattended but also applicable for other purposes.
According to my invention 1 provide a curved bar of metal or other suitable
material, the said bar being preferably somewhat U-shaped and to the end of one
of the limbs I hinge one end of a second bar the other end of which is adapted to
be locked with the end of the other limb of the curved bar in the usual manner.
To enable my invention to be fully understood I will describe it by reference to
the accompanying drawing, in which :-
Figure 1 is a side elevation of my improved lock shewing the same closed; and,
Figure 2 is a sectional elevation of the lock shewn in its open position.
a is the U-shaped or curved bar and b is the second bar which is hinged at c to
the end of one limb of the U-shaped bar a.
The free end of the bar b is recessed or made hollow to receive a bolt d
designed to engage with a notch e on a catch upon the free end
bar a which catch enters the hollow end of the bar b. 9, 9 are
normally hold the said bolt in engagement with the notch e and
of the curved
springs which
is a pin upon

page_text: which the stem or pipe of the key turns for disengaging the bolt d from the notch
so as to allow the lock to be opened.
It will be obvious that my improved lock dispenses with the necessity for a chain
when securing a cycle as the lock itself can be passed through any suitable parts of
the machine so as to lock it.
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:-
The improved lock consisting of the two bars a and b hinged together at c, one
end of the bar b being hollow to receive a spring bolt d which engages with a
catch on the free end of the bar a, substantially as described and illustrated in the
accompanying drawing.
