& Co., Patent Agents, Southampton Buildings, London, for the Invention of
"IMPROVEMENTS IN PADLOCKS." A communication from abroad by Johann
Fetter, of Cracow, in the Empire of Austria.
PROVISIONAL SPECIFICATION left by the said William Robert Lake at the
Office of the Commissioners of Patents on the 18th January 1879.
WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. IMPROVEMENTS IN PADLOCKS." [A communi-
cation from abroad by Johann Fetter, of Cracow, in the Empire of Austria.]
This Invention relates to improvements in padlocks, which improvements have
for their object the construction of padlocks in such a manner that the latter may,
without any further additional appliance, be used for a number of purposes for
which they could not hitherto be employed without adding other arrangements.
The padlocks constructed according to the present improvements can, without
requiring any other devices, be at once used for connecting objects not closc
together; for fastening and locking different sizes of bundles of papers or books or
clothing; for fastening and locking horses and cattle; for handcuffing one or more
prisoners; for fastening different sized mouths of sacks, and for many other
purposes.
The said improvements consist essentially in replacing the ordinary rigid bow or
shackle in padlocks by a flexible chain, cord, or band, one end of which passes
entirely through the padlock-caso, and is movable to and fro in the same until
locked in the ordinary manner. The said padlock is provided with a channel
leading entirely through the case past the bolt, thereby enabling the chain, or cord,
or band to be passed through the said channel and locked by the bolt at any part
of its length so that the holding portion of the chain may be as short or as long as
required to suit the particular circumstances under which it is to be used.
The chain, cord, or band may be of any convenient length, and may at the same
time be arranged so as to pass through a number of separate rings fixed on the same

articles at the same time. Ŏr one and the same chain may be passed through a
second separate padlock or through a number of separate padlocks. Or a double
padlock may be used and the chain be free at both ends until locked at suitablo
parts in the said padlock. Or the two separate chains may be used on the same
padlock, and passing through the same channel, be locked by the same bolt. Instead
of one end of the chain being permanently fixed it may be passed through a second
channel in the same padlock-case and be provided with a ring or button at one end
so that it can be pulled through the lock-case in one direction but not in the
other.

WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, Loudon. IMPROVEMENTS IN PADLOCKS." A communi-
"
cation from abroad by Johann Fetter, of Cracow, in the Empire of Austria.
This Invention relates to improvements in padlocks, which improvements have
for their object the construction of padlocks in such a manner that the latter may,
without any further additional appliance, be used for a number of purposes for
which they could not hitherto be employed without adding other arrangements.
The padlocks constructed according to the present improvements can, without
requiring any other devices, be at once used for connecting objects not close together,
for fastening and locking different sizes of bundles of papers or books or clothing,
for fastening and locking horses and cattle to posts or other suitable objects, for
handcuffing one or more prisoners, for fastening differently sized mouths of sacks,
and for many other purposes.
The said improvements consist essentially in replacing the ordinary rigid bow
or shackle in padlocks by a flexible chain, cord, or band, one end of which passes
entirely through the padlock-case and is moveable to and fro in the same until
locked in the ordinary manner. The said padlock is provided with a channel
leading entirely through the case past the bolt, thereby enabling the chain, cord,
or band to be passed through the said channel and to be locked by the bolt at any
part of its length, so that the holding portion of the chain may be as short or as
long as required to suit the particular circumstances under which it is to be used.
In the accompanying Drawing,-
Figures 1 to 18 show different arrangements of the chain, cord, or band employed
in connection with the said padlock, and Figures 19 to 23 show the internal con-
structions of locks provided with the said improvements.
Figure 1 represents a padlock provided with the present improvements and
showing the same unlocked.
Figures 2 and 3 are a front and sectional view of a padlock when locked.
Figure 4 shews the padlock without the chain or cord.
Instead of one end of the chain being permanently fixed it may be passed through
a second opening in the same padlock-case and be provided with a ring or button
at one end, as shown in Figures 5 and 6, so that the said chain can be pulled out
of the lock-case in one direction but not in the other.
The chain, cord, or band may be of any convenient length, and may be so
arranged as to pass through more than one ring fixed on the same padlock, as shewn
in Figures 7 and 8, or more than one channel in the same padlock-case, as shown
in Figures 13, 14, and 15, and when thus arranged will serve for holding and
locking a number of separate articles at the same time.
Figure 9 shews an arrangement with two separate chains, cords, or bands side
by side.
Figure 10 shews two chains, cords, or bands, lying one above the other, and with
their ends passing through the same channel in the padlock.
In some cases I employ a double padlock, as shewn in Figure 11, and the chain
may be free at both ends a*, b*, until locked at suitable parts in the said padlock,
the chain being fixed or sliding to and fro in the ring fixed on the padlock-case.
Or two chains or cords may be used in a similar manner with two separate locks
in the said padlock-case, as shown in Figure 12. Or one and the same chain may
be passed through a second separate padlock, or through a number of separate pad-
locks, as shewn in Figures 16 and 17.
Figure 18 represents an ordinary padlock with a rigid bow or shackle, and which
has been converted into a padlock according to the present Invention by attaching
a chain and perforating the case for the passage of the end of the said chain.

page_text: Figures 19 to 23 illustrate the manner in which the bolt or internal mechanism
may engage with the chain for effecting the locking action; Figures 19 and 22 shew
the padlocks unlocked, and Figures 20, 21, 23 shew the same locked.
In these Figures a represents the bolt, b the lock-spring, and c the key. In
Figure 23, d is a projection against which the chain is held by the bolt a when
locked.
Having thus fully described the said Invention as communicated to me by
my foreign correspondent, and the manner of performing the same, I wish it
understood that I claim,-
First. The general arrangement and construction of padlocks in which the
ordinary rigid bow or shackle is replaced by a flexible chain, band, or cord passing
through the padlock-case and movable to and fro in the same until locked, sub-
stantially as and for the purposes specified.
Second. The special construction of such padlocks, substantially as described and
shown in the accompanying Drawing.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Fifteenth day of July, in the year of our Lord One
thousand eight hundred and seventy nine.
