IMPROVEMENTS IN LOCKS
Year: 1853

page_text: LETTERS PATENT to George Fredric Goble, of 15, Fish Street
Hill, in the City of London, Civil Engineer, for the Invention of
IMPROVEMENTS IN LOCKS."
Sealed the 3rd November 1858, and dated the 3rd May 1858.
PROVISIONAL SPECIFICATION left by the said George Fredric
Goble at the Office of the Commissioners of Patents, with his
Petition, on the 3rd May 1858.
I, GEORGE FREDRIC GOBLE, of 15, Fish Street Hill, in the City of
London, Civil Engineer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN LOCKS" to be as follows:-
My Improvements relate, firstly, to a novel arrangement of simple
parts in the interior of door and other locks, and in keys to be used
for the same, by a peculiar application of springs; and, secondly, to a
modification of double acting levers or slides, by adopting which it
becomes unnecessary to have either spring, tumbler, screws, or wards.

page_text: For the better understanding of iny said Invention, I will now
proceed to describe the several parts thereof, reference being had to
the annexed Drawings, in which the same letters & figures of refer-
ence indicate the same parts in each.
Fig. 1, a sectional view of a padlock, in which the shackle «<, is
fastened as usual at b. It receives a series of levers or slides at c, to be
set at a definite distance, so as to enable the lock to be opened or closed.
d, the bolts, with corresponding centre oblong apertures, kept in their
place by two pins e, e. The springs f, keep the bolts in proper tension.
The keyholes may be at c, or at any convenient point between c, and y.
Notches or grooves are to be cut ath, to match, and receive the ends of
the bolts d.
Fig. 2, a sectional view of another form of padlock, in which the
shackle has a circular motion within the case, and the bolts d, act in
corresponding grooves cut in the shackle at h, h, to receive them.
i,,, may either be studs or holes, placed in any desired situation, and
can be actuated either with or without a key.
Fig. 3, a sectional view of a door lock; d, d, the bolt; d', ', a
series of double-acting levers working on the pins é, e; the spring f,
presses the bolt d; the key holes are here shown at c, c, c; while at j.
is a knob or handle by which to draw back the bolt d.
Fig. 4, is a sectional view of another form of door lock, with my Im-
provements; c, c, c, distinguishing the keyholes; d, d, d, the bolt;
d', d', ', a series of springs acting as levers or securitics; f, a spring
to work the bolt d; and j, the knob or handle. The key, is made
with a series of studs 7, 7, with a spring to each at m, m, m.
Having thus described two modes of constructing padlocks, and two
modes of constructing door or other locks, I would here observe that I
do not restrict myself to any particular form, dimensions, or material,
for such or any other locks whatever; and in respect to their interior S
arrangements, although I have only described four different plans,
these may be variously modified in regard to the size and form of the
levers or slides, springs, bolts, and configuration of keys, but still retain-
ing the principle of my improvements. And I do declare that what I

page_text: claim as my Invention is, the peculiar arrangement of double-acting
levers, slides or springs, either combined or separately applied to
locks and keys, as herein described.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Fredric Goble in the Great Seal Patent
Office, on the 3rd November 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I.
GEORGE FREDERIC GOBLE, of 15, Fish Street Hill, in the City of
London, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing dato the Third day of May, in the year of our
Lord One thousand eight hundred and fifty-three, in the sixteenth,
year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said George Frederic Goble, Her special
licence that I, the said George Frederic Goble, my executors, ad-
ministrators, and assigns, or such others as I, the said George
Frederic Goble, 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 law-
fully 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," upon the condition (amongst
others) that I, the said George Frederic Goble, by an instrument in
writing under my hand and seal, should particularly 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 George Frederic Goble, 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:

page_text: parts in the interior of door and other locks, and in keys to be used
for the same, by a peculiar application of springs; and, secondly, to a
modification of double acting levers or slides, by adopting which it
becomes unnecessary to have tumblers, screws, or wards.
For the better understanding of my said improvements, I will now
proceed to describe the several parts thereof, reference being had to the
annexed drawings, in which the same letters and figures of reference
indicate like parts in each.
"
DESCRIPTION OF THE DRAWINGS.
Figure 1, is a sectional view of a door lock, the principle being also
applicable to padlocks, and to other descriptions of locks. a, is the
bolt; the front edge of the case; c, c, receives a series of levers or
slides, to be set at a definite distance, so as to enable the lock to be
opened or closed; d, the bolts or slides, with corresponding centre
oblong apertures, kept in their place by two pins e, e, while the
springs f, retain the bolts in proper tension. The keyholes inay
at c. I would observe that in constructing padlocks, the shackle may
have a circular motion, within a round case, and the bolts d, may act
in corresponding grooves cut in the shackle to receive them, and the
bolts may have either studs or holes placed in any desired situation, to
be actuated either with or without a key.
be
Figure 2, is a sectional view of another form of door lock. a', is the
bolt; b', the front part of the case; c, receives a series of springs,
bolts, or slides, d, of which ten are here shown, acting as securities to
the bolt a; e, e', two pins to keep the bolt in its place; f¹, a spring
acting on the bolt.
Figure 3, is a side view of one of the springs or bolts d', Figure 2,
showing its arrangement.
Figure 4, is an end view of the bearer c', Figure 2, carrying the
ten bolts d', showing the slots c¹, to receive the front ends of the bolts.
Figure 5, represents the key k. having a series of ten studs 1, 1, 1,
with a spring to each at m, n, m, and suitable for the lock, Figure 2.
Having thus described my methods of constructing padlocks, door

page_text: and other locks, I wish it to be understood that for locks with handles,
I prefer a pendulous lever to act on the inner bolt, with a rack and
tooth, as at c", Figure 1; also, that I neither use nor claim tumblers,
but employ sliding bolts to act independent of tumblers for locks of
every description; and that I do not restrict myself to any particular
form, dimensions, or material for my improved locks; and in respect to
their interior arrangements, these may be variously modified in regard
to the number, size, and form of the levers or slides, springs, bolts,
teeth, and configuration of keys, but still retaining the principle of my
improvements. And I do declare that what I claim as my Invention
is, namely, the peculiar arrangement of double acting levers, slides, or
springs, either combined, or separately applied to locks and keys, as
herein described.
In witness whereof, I, the said George Frederic Goble, have
hereunto set my hand and seal, this Third day of November,
in the year of our Lord 1853.
G. F. GOBLE. (L.S.)
