County of Lancaster, for the Invention of "IMPROVEMENTS IN LOCKS
OR FASTENINGS, PRINCIPALLY INTENDED AS A SUBSTITUTE FOR ORDINARY
PADLOCKS."
Scaled the 17th December 1872, and dated the 10th July 1872.
PROVISIONAL SPECIFICATION left by the said Henry Lancaster at the
Office of the Commissioners of Patents, with his Petition, on the
10th July 1872.
V
I, HENRY LANCASTER, of Bolton-le-Moors, in the County of Lan-
"Im-
caster, do hereby declare the nature of the said Invention for
PROVEMENTS IN LOCKS OR FASTENINGS, PRINCIPALLY INTENDED AS A SUBSTITUTE FOR
ORDINARY PADLOCKS," to be as follows:-
The parts of an ordinary padlock or hanglock upon which the security.
of the fastening mainly depend are exposed, and the lock being moveable
to some extent is easily tampered with or broken away, and the object of

page_text: my Invention is to give increased, strength and protection to the
fastening, and make the lock immoveable when locked, and my Inven-
tion consists in a combination and arrangement of parts, namely, there
is a plate secured to the door or other part to be locked, in which plate
the staple, eye, stud, or other equivalent part is secured, and holes or
recesses are also formed in the said plate with which bolts or equivalent
parts become connected to make the lock immoveable when locked.
The bolts which enter the staples or recesses in the said plate are fitted
to slide in a casing or cover, and they are caused to shoot into the
staples or recesses by a cam, cam slot, or slots, excentric, crank pin, rack
and pinion, or other equivalent, which cam, excentric, crank, or pinion is
formed or secured upon a short shaft having bearings in the said casing
or cover by rotating or partially rotating a handle upon the said short
shaft at the exterior of the said casing or cover; then the short shaft is
prevented from being turned back to withdraw the bolts by the bolt of
any ordinary lock secured in the said casing or cover, which bolt is
shot by the key into a notch in a disc secured in the said short shaft.
The bolts which enter the staples or recesses in the plate may be either
separate or connected together.
According to another modification of my Invention the sliding bolts
are dispensed with and the cover or casing has notches formed in its
inner face which will pass into a staple or behind the head of a stud in
the fixed plate when placed over them and slided endways, the cover or
casing being then secured by a short shaft and handle, the end of the
shaft entering a recess in the fixed plate, and the short shaft is locked as
herein-before explained.
.
Another modification applicable for such purposes as folding doors
consists of a casing and plate combined, which is permanently attached
to the door to be secured. The bolt is shot by a handle and short shaft,
and the short shaft is locked as before explained.
My improved locks may be used to cover and secure the keyhole of
safe locks and strong rooms, to give further security.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Lancaster in the Great Seal Patent Office
on the 8th January 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
LANCASTER, of Bolton-le-Moors, in the County of Lancaster, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of July, in the year of our
Lord One thousand eight hundred and seventy-two, in the thirty-sixth
year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Henry Lancaster, Her special license
that I, the said Henry Lancaster, my executors, administrators, and
assigns, or such others as I, the said Henry Lancaster, my executors,
administrators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel.
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN LOCKS OR
FASTENINGS, PRINCIPALLY INTENDED AS A SUBSTITUTE FOR ORDINARY PADLOCKS,"
upon the condition (amongst others) that I, the said Henry Lancaster,
by an instrument in writing under my hand and seal, should par-
ticularly describe and ascertain the nature of the said Invention, and.
in what manner the same was to be performed, and cause the same to
be filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Henry Lancaster, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement and the accompanying Drawings (that is to say):-
The parts of an ordinary padlock or hanglock upon which the security
of the fastening mainly depend are exposed, and the lock being moveable
to some extent is easily tampered with or broken away, and the object.
of my Invention is to give increased strength and protection to the
fastening and make the lock immoveable when locked, and my Inven-
tion consists in a combination and arrangement of parts, namely, there

page_text: is a plate secured to the door, or other part to be locked, in which plate
the staple, eye, stud, or other equivalent part is secured, and holes or
recesses are also formed in the said plate, with which bolts or equivalent
parts become connected to make the lock immoveable when locked.
The bolts which enter the staples or recesses in the said plate are fitted
to slide in a casing or cover, and they are caused to shoot into the staples
or recesses by a cam, cam slot, or slots, excentric, crank pin, rack and
pinion, or other equivalent, which cam, excentric, crank; or pinion is
formed or secured upon a short shaft having bearings in the said casing
or cover by rotating or partially rotating a handle upon the said short
shaft at the exterior of the said casing or cover; then the short shaft is
prevented from being turned back to withdraw the bolts by the bolt of
any ordinary lock secured in the said casing or cover, which bolt is shot
by the key into a notch in a disc secured on the said short shaft. The
bolts which enter the staples or recesses in the plate may be either
separate or connected together.
According to another modification of my Invention the sliding bolts
are dispensed with, and the cover or casing has notches formed in its
inner face which will pass into a staple or behind the head of a stud in
the fixed plate when placed over them, and slided endways, or moved
sideways, or partly rotated, the cover or casing being then secured by a
short shaft and handle, the end of the shaft entering a recess in the
fixed plate, and the short shaft is locked as herein-before explained; or by
one modification when the casing is moved sideways it is secured by the
bolt of an ordinary lock shot by the key.
My improved locks may be used to cover and secure the keyhole of
safe locks and strong rooms to give further security, in which case the
plate is secured in front of the keyhole of the safe, but so that the key
can be inserted when the casing part is removed, or the keyhole plate of
the safe is made to suit the casing which is to be locked to it, to cover
and secure the keyhole..
Fig. 1 is a front view of a plate; Fig. 2, a section through the case
and plate; and Fig. 3, a view of the case with the covering plate removed
to shew the interior of the casing; these three views illustrating one
modification of my Invention. a is the plate secured to the door or other
part to be locked by the screws a', or other means; a³ is the staple or eye

page_text: formed upon it, and a³ are projections having holes, in which bolts shoot
to secure the casing to the plate; bis the casing; 6¹, two projections
from its interior, in which there is a hole for the pin or bolt c¹, which
passes through the eye of the staple a³. This pin c¹ is formed upon a
frame c which has two bolts c² at its lower end that pass through holes in
the casing b. There is a short shaft d, one end of which comes through
the front of the casing and has its bearing therein; the other end has.
its bearing in a cross bar 6º secured to the casing by screws; d' is a disc
secured upon the short shaft d, and d is an excentric also secured or
formed upon
the shaft; and d is a handle secured upon the end of the
short shaft. The excentric works between two cross bars C³, forming
part of the frame c; e is a plate that covers the works in the casing 6;
fis any ordinary and suitable lock secured in the casing f¹, representing
the key. The bolt få of the lock is made to shoot into a notch in the.
disc when the bolts C¹ and C³ have been shot by turning the.
handled into the position shown by Figs. 2 and 3, so that the handle
cannot be again turned back until the lock bolt is withdrawn by the
key. The bar or part secured between the plate a and casing 6 is
represented by g.
Fig. 4 is a front view of a box plate, and Fig. 5 is a section of the
plate and casing of another modification; a² is the staple formed in the
plate a; b is the casing; f is any suitable ordinary lock; f¹, a slide plate
for covering the keyhole; f³, the bolt of the lock which shoots through
holes in projections 6 from the casing, and the eye in the staple
part; 9 is the bar or part secured between the plate and casing. The
casing fits into the box plate like a lid into a box, as shown.
'
Fig. 6 is a view of the plate; Fig. 7, an inside view of the casing, and
Fig. 8 is a section of the plate and casing secured together. a² is the
stud formed upon the plate a for the part (9) to be secured. a* is a
circular rim upon the plate a; parts are cut out of this rim and under
cut so that projections 6³ from the inside of the circular rim on the
casing 6 can enter the notches and pass under the under cut parts when
the casing is slightly rotated. The projection 63* passes under or in a
notch in the side of the stud a³, and thus the projections secure the
casing. b. to the plate a, and the part (g) on the stud a* between
them. is an ordinary and suitable lock, and f¹ represents its key.
When the casing is turned so that the projections 6s have passed under

page_text: the under cut parts, the bolt f* of the lock is shot out by the key to pass
into one of the holes cut out of the rim a*, and this prevents the casing
from being turned back until the bolt of the lock is again withdrawn by
the key.
Figs. 9, 10, 11, 12 and 13, are views illustrating another modification;
Fig. 9 is a section through the plate and casing; Fig. 10, a front view
of the casing secured to the plate; Fig. 11 is an inside view of the
casing; Fig. 12, a front view of the plate alone; and Fig. 13, an end
view of it. a is the plate secured to the door or other part; a² the stud;
g the part secured between the plate and casing. The stud is under cut,
so that an under cut recess b* in the casing can pass upon and then slide
so that the under cut sides of the recess will come under the head of the
stud, a part 6 at the end of the casing at the same time entering a
recess in the plate a; d is a short shaft, having bearings in the casing b,
and in a plate 6* secured to the casing by screws. The end of the short
shaft has a dovetail part which when turned as shewn in Fig. 11, can
enter the slot a* in the plate a, and when the casing 6 has been
placed in the position shewn in Fig. 7 the handle is turned in the
circular part of the slot a* in the plate (a). Any ordinary and suitable
lock is secured in the casing at f, and its bolt is made to shoot into a
notch in a disc d on the shaft so as to prevent it from being turned
when locked by the key.
Fig. 14 is a sectional view of the plate and casing, and Fig. 15 is an
inside view of the casing representing another modification. a is the
plate; a is a button or stud secured in the plate b; the casing d is a
short shaft having a bass part recessed or under cut to fit the stud; the
recessed part being open on one side. The short shaft d is kept in its place
by a plate b* secured to the casing, and this plate is slotted as shown.
The circular hole in the plate 6* is passed over the head of the stud, and
then the casing is slided down into the position shewn in Fig. 14; then
the handle d³ is turned until the upper part d* of the boss is brought
across the slot, and the bolt of any ordinary and suitable lock is shot out
by the key (fx representing the pin for the key) to come in the way of
a projection from the disc d on the short shaft, and prevent it from
being turned back until the lock bolt is shot back by the key. . is a
stop to come in contact with the part cut away from the disc, and limit
the extent of movement of the short shaft in both directions.

page_text: I have now particularly described the nature of my Invention, and
the mode of carrying it into effect, and claim as my Invention, locks or
fastenings formed by a plate (a) and casing 6 with the mechanism
combined and arranged, substantially as herein-before described and
illustrated by the Drawings.
In witness whereof, I, the said Henry Lancaster, have hereunto set
my hand and seal, this Seventh day of January, in the year of
our Lord One thousand eight hundred and seventy-three.
