AN IMPROVED LOCK AND KEY," com- municated to me by a certain foreigner residing abroad
Year: 1835

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
WARRICK, of No. 9, Three Kings' Court, Lombard Street, Merchant, send
greeting.
WHEREAS His present most Excellent Majesty King William the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, the Sixteenth day of December, in the sixth year of His
reign, did, for Himself, His heirs and successors, give and grant unto mo, the
said John Warrick, His especial licence, full power, sole privilego and
authority, that I, the said John Warrick, my exors, adñiors, and assigns, or
such others as I, the said John Warrick, my exors, adñiors, 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 "AN IMPROVED LOCK AND KEY," com-
municated to me by a certain foreigner residing abroad;" in which said
Letters Patent is contained a proviso that I, the said John Warrick,
shall cause a particular description of the nature of the said Invention, and
in what manner the same is to be performed, to be inrolled in His 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

page_text: 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
John Warrick, do hereby declare that the nature of the said Invention con-
sists in a peculiar lock, which cannot be opened except by its own key, and the
manner in which the same is to be performed is fully represented by the
Drawings hereunto annexed, and the following explanation of the same, that
is to say:-
Sheet 1. Figure 1 is a transverse section of a lock and safety appendage
according to my plan. a, a, is the box or barrel, in which the safety apparatus
is enclosed; b is the box of the lock; c, a spiral spring coiled round the central
shaft d, which spiral spring is attached to the sliding collet c; f is the key,
inserted the first step into the lock; g, g, are two circular plates of metal con-
nected by two pins h. By forming a turning drum the pins h, h, act as teeth,
and in revolving catch into corresponding notches in the bolt i, i. j is a lever,
which also acts from the turning drum upon the draw bolt ; 1,, are knobs
to withdraw the draw bolt by hand. is a ward pin, and a bolt ward pin,
inserted in grooves on the inner side of the interior barrel m, which are more
clearly shown in Figures 4, 5, and 6. n is the ward plate, which is fixed to the
barrel of the safety appendage by the screws a, a. Figure 2 is the key out of
the lock. Figure 3 is the central shaft and spiral spring detached from the rest
of the apparatus. Figures 4, 5, and 6 are side, top, and bottom views of the
interior barrel, also one of the four ward pins 1, 1, 1, 1, and the bolt ward pin l',
taken out of their grooves; n+, notches in the ward pins; those ward pins are
of different lengths, according to the different heights of the teeth on the key.
Figure 7 is a plan of the ward plate, which is divided into two pieces, and fits
into the groove o round the interior barrel on.
Sheet 2.--Figure 8 is a view of the face of the lock. Figure 9 is an interior
view of the lock, the front plate and safety appendage being removed; the
several parts are distinguished by the same letters as are used in the Figures
in Sheet 1. p, p, p, p, are the teeth in the bolt i; g is a spiral spring coiled
round the end of the draw bolt, tending to keep it out; is a lever, which is
made to bear down upon one of the plates of the turning-drum g by the spring
8, so as to controul and regulate the movement of the bolts i, k. Figures 10
are four different forms of keys, and Figures 11 corresponding key-hole plates,
with apertures formed so as to admit their several keys. And I hereby
further declare that the action of the lock is as follows, that is to say:-
Upon inserting the key fit enters a chamber ; it is then turned round until

page_text: the projecting key piece u falls into an indentation in the top of the inner
barrel at w, when it rests on the head of the bolt ward pin l, and the teeth
on the shank of the key also rest severally on the top of the ward pins 1, 1, 1, 1,
the key is then pressed forward, depressing the spiral spring, and moves the
ward pins 1, 1, 1, 1, 1, until each notch u therein coincides with the circular
ward plates n; the bolt ward pin will then have entered a slot or hole y
in
the turning drum, thereby connecting the safety apparatus with the lock.
Upon turning the key the whole inner barrel will revolve in the groove of the.
ward plate n, carrying with it the turning drum, the pins of which, as it
revolves, take into the notches in the bolt i, and which will in consequence be
propelled forward, or withdrawn, and in the latter case the pins also further
act upon the short end of the lever j, and withdraw the bolt k.
It will be seen
that until the ward pins 1, 1, 1, 1, are depressed, so as. that their notches coin-
cide with the ward.plate n, the inner barrel cannot revolve in consequence of
the said ward pins catching in the notches of the ward, plate, and thus holding
the inner barrel fast. And I further declare that the herein-before described
safety apparatus may be applied to any kind of lock or bolt, and that I do not
confine myself to the lock herein-before described, but which, in combination
with the said safety appendage, I consider the most secure and convenient.
And I also further declare that I do not confine myself to the shape or shapes
of keys, or to the number, shape, and size of the ward pins herein-before
described; but generally that I claim every variation in these and other points,
so long as the principal features of the combination herein set forth and
described are retained. And I further declare that I do not claim as the
Invention any of the said springs, bolts, pins, or other things before mentioned,
separately or otherwise than in so far as the same are newly combined and
arranged in the manner herein-before described, and in the Drawings here-
unto annexed. And I declare, that what I claim as the Invention com.
municated to me is, the particular combination of means before described,
forming in its entirety a lock which can only be opened by means of its own
key, and will resist every sort of picklock or false key, and which differs from
every other safety lock heretofore known in this country.
In witness whereof, I, the said John Warrick, have hereunto set my
hand and seal, this Sixteenth day of June, in the year of our Lord
One thousand eight hundred and thirty-six.
JOHN (L.S.) WARRICK.
