Year: 1840

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FRANCIS
WILLIAM GERISH, of East Road, City Road, in the County of Middlesex,
Patent Hinge Maker, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Twentieth day of March, in the third year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said Francis William Gerish, Her especial licence, full power, sole privilege
and authority, that I, the said Francis William Gerish, my exors, adors,
and assigns, or such others as I, the said Francis William Gerish, my exors,
admors, or assigns, should at any time agree with, and no others, from time
to time and at all times during the term of years therein expressed, should
and lawfully might make, use, exercise, and vend, within England, Wales,
and the Town of Berwick-upon-Tweed, my Invention of "IMPROVEMENTS IN
LOCKS AND KEYS, AND IN OTHER FASTENINGS FOR DOORS, DRAWERS, AND OTHER SUCH
PURPOSES;" in which said Letters Patent is contained a proviso that I, the
said Francis William Gerish, shall cause a particular description of the nature
of my said Invention, and in what manner the same is to be performed, to be
inrolled in Her said Majesty's High Court of Chancery within six calendar
months next and immediately after the date of the said in part recited
Letters Patent, as in and by the same, reference being thereunto had, will
more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said

page_text: Francis William Gerish, do hereby declare that the nature of my said
Invention, and the manner in which the same is to be performed, are
particularly described and ascertained in and by the following statement
thereof, reference being had to the Drawing hereunto annexed, and to the
figures and letters marked thereon (that is to say) :-
My Invention relates,―
1
First, to a mode of constructing locks in such manner that the same are
made secure by the application of a lock to the knob or handle, by which
means in making the lock for a door or other similar purpose, where it would
require considerable weight of key to move the bolt, and where great security
is required, the whole of the lock, as well as the lock, requires to be made
referable thereto by numerous wards, tumblers, or instruments varying in
their figure, in order to present as many difficulties in the way of picking the
lock as possible by means of false keys or picklocks; but by applying a small
lock and key to the knob or handle of a lock, and thus have the means of
locking the knob or handle from operating on the bolt, the large and strong
lock may be of the simplest action, having simply means of connecting the
motion of the axis of the handle to draw back the bolt, and constructing the
small lock acting to lock the handle or knob of any convenient construction to
offer the degree of security desired, and by so doing the key to be carried for
even for the largest locks will be small, as the requisite strength to actuate
the strong bolt or bolts of the lock will be in the axis of the knob or
handle.
Secondly, my Invention relates to a simple mode of constructing a lock or
such like fastening within a tube, whereby in applying the same there will be
much less cutting away of the wood of the door or other place of its
application.
Thirdly, my Invention relates to a mode of constructing keys of locks,
which act by means of tumblers, by applying a series of nebs or projections
around the axis of the key.
And in order to give the best information in my power, to enable a work-
man to perform my Invention, I will proceed to describe the Drawing here-
unto annexed.
DESCRIPTION OF THE DRAWING.
Figure 1 represents a side view and section of a knob or handle of a door, with
a common tumbler lock fixed therein. a is a bolt, which is forked, and enters
into openings formed in the escutcheon b, and thus holds the knob or handle
from being turned round. The escutcheon 6 is made fast to the door by
screws passing from the inside thereof. I would remark that it will be

evident that although I have shewn a particular construction of locks as
applied to the handle or knob, I do not confine myself thereto, as the
requisite bolt or bolts may be thrown from a knob or handle by other arrange-
ments of wards, tumblers, and instruments, this part of my Invention
not depending on the internal arrangement of the lock applied to the knob
or handle, but to the application of suitable locks to knobs or handles of
locks; and although I prefer to apply a lock within the handle or knob of a
lock, yet I would remark that the axis of the handle or knob may be locked
or fastened by applying a lock in the escutcheon of the lock, and throw the
requisite bolt or bolts therefrom into the handle or knob, and I have shown
at Figure 2 a means of so applying a lock.
like fastening, made within a tubular case.
case with the works applied, and Figure 5
a is the bolt, which has a toothed rack formed thereon. 6 is the axis of the
handles or knobs, on which is affixed a pinion or toothed sector, which
taking into the rack a, moves the bolt a, there being a coiled spring c
around the stem of the bolt a, which at all times tends to force the bolt out-
wards. It will be seen that the knobs or handles are arranged according to
the first part of my Invention, having a lock applied to one of them, that is,
the outside one; and the inside knob or handle is rendered secure by a sliding
bolt e sliding from within the handle or knob, or else by a sliding bolt f
sliding from the escutchion into the handle or knob. Figure 6 shows the
mode of constructing a key, with a series of nebs or projections placed at
different angles around the axis of the key. Figure 7 shows a side view of a
knob or handle, containing a lock suitable for the key shown at Figure 6.
Figure 8 is a side section, and Figure 9 a cross section of Figure 7. a is
the bolt, which has two projections for entering into the escutcheon b, but a
greater number may be applied according to the strength of bolt required.
c, c, are two tumblers, which are acted upon to relieve the bolt by the
nebs c', c, of the key, the nebs 3 being applied to move the bolt a.
By this
arrangement of the nebs around the axis of the key greater security from the
picking of the lock will be obtained.
Having thus described the Invention, and the manner of performing the
same, I would have it understood that what I claim is,-
First, the application of a lock and key to a knob or handle of a lock to
secure the same, as herein described.
Secondly, I claim the mode of constructing a lock or other such like fasten-
ing by combining a bolt a, spring c, and pinion or toothed sector b, within a
tubular case, as described. And,

page_text: Thirdly, I claim the mode of constructing a key for locks and other such
fastenings, by having a series of nebs or projections around the axis of the key,
as described.

set my hand and seal, this Nineteenth day of September, in the year of 5
