page_text: C. AND J. CHUBB'S SPECIFICATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
CHUBB, Patent Lock and Wrought-iron Safe Manufacturer, of Saint Paul's
Churchyard, in the City of London, and JEREMIAH CHUBB, of Red Lion
Street, Clerkenwell, in the County of Middlesex, Machinist, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Eleventh day of June, in the second year of Her reign, did, for
Herself, Her heirs and successors, give and grant unto us, the said Charles
Chubb and Jeremiah Chubb, Her especial licence, full power, sole privilege
and authority, that we, the said Charles Chubb and Jeremiah Chubb, our
exors, adiñiors, and assigns, or such others as we, the said Charles Chubb and
Jeremiah Chubb, our exors, adiñiors, or assigns, should at any time agree with,
and no others, from time to time and at all times thereafter 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, our
Invention of "IMPROVEMENTS IN APPARATUS AND MACHINERY FOR PRESERVING
BOOKS AND OTHER PAPERS, DOCUMENTS, AND ARTICLES FROM FIRE;" in which said
Letters Patent is contained a proviso that we, the said Charles Chubb and
Jeremiah Chubb, or one of us, shall cause a particular description of the
nature of our 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, we, the said
Charles Chubb and Jeremiah Chubb, do hereby declare the nature of our

page_text: said Invention, and the manner in which the same is to be performed, are
fully described and ascertained in and by the following statement thereof,
reference being had to the Drawings hereunto annexed, and to the figures and
letters marked thereon (that is to say) :-
Our Invention relates to a combination of apparatus or machinery for
raising and lowering chests, safes, or boxes containing books, papers, docu-
ments, and other articles from and into places suitably constructed to be
fireproof. We would remark that various constructions of apparatus or
machinery for raising and lowering similar chests, safes, and boxes for like
purposes; we do not therefore claim the constructing fireproof chambers,
from and into which such articles are to be placed, but our Invention relates
only to a mode of combining certain mechanical apparatus or machinery with
suitable fire wolls on chambore
The Drawings represent various Figures, the nature of each of which is
written thereon, and it should be remarked that the same letters of reference
are used to denote the same parts on all the Figures. a, a, represents a we
or chamber constructed of brick, stone, or other suitable material for making
the same proof against any fire which could possibly occur in the locality
where the chamber a, a, is constructed. Supposing, for instance, it was at
a banker's premises, b, b, would represent the surface of the floor of the office
in which during business hours the safe, chest, or other such closet would be
required to be used, and a, a, will then represent a descending chamber or
well, which may be of brick or other material, and for security against
depredation the same may be lined with iron. c, c, is a platform on which
the iron or other chest or closet is placed, and it may, if desired, be affixed.
This platform is carried by four chains d, d, which chains pass over to wheels
e, e, suitably constructed for the teeth entering into the links of the chains;
ff, are weights to counterbalance the chest or closet and its contents. The
chain wheels e, e, are affixed on the two shafts 9, 9, turning in suitable
bearings, as is shown in the Drawings, and on these shafts g, g, are affixed
two screw wheels or wheels h, h, with teeth suitably formed for being. driven
by screws; and h¹, h¹, are two screws affixed on the shaft i, such screws
taking into drive the wheels h, h, and by this means raise or lower, the plȧt-
form and the chest thereon. The shaft i receives motion in the following
manner is a bevelled toothed wheel affixed on the shaft or axis. i, and k
is another bevelled toothed wheel affixed on the shaft l, which I call the key
shaft, as on this shaft or key is fitted, and by the intervention of the key such

page_text: shaft is caused to revolve in the following manner, or the key shaft may rise
above the floor and have motion communicated directly thereto in place of
using a key:-m is an upright or framing, which is capable of being affixed
to the floor and removed, if desired, when out of use; n is a key, which fitting
on the axis will cause it to revolve when it is turned. On the key is affixed
a bevelled toothed wheel o, which takes into and is driven by a toothed wheel
p on the cranked axis q, all which is clearly shewn in the Drawings, and will
readily be traced. r is a door or cover for the chamber or well a, a, and is
suitably arranged to be carried up with the iron chest A, as is shewn by the
dotted red lines, there being suitable pins in the upper part of the chest A to
enter suitable recesses, and thus when the chest rises it carries up the cover,
and when the chest descends it correctly places the door in its proper situation,
and there being suitable locks of the best kind applied to the door, the same
are to be locked to secure the chamber a from being entered, or the chest
lifted without using the proper keys. And in order to prevent persons raising
the chest, even supposing the door is unlocked, the key may be removed and
kept in a safe place.
Having thus described the nature of our Invention, and the manner of
performing the same, we would remark that we lay no claim to any of the
parts separately; but what we claim is the mode of combining the apparatus
or machinery, as above described.
In witness whereof, the said Jeremiah Chubb, have hereunto set my hand
and seal, this Eleventh day of December, in the year of our Lord One
thousand eight hundred and thirty-nine
