Year: 1840

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BENJAMIN
BAILLIE, of Henry Street, Regent's Park, Glazier and Metal Worker, 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 Twenty-third day of December, in the fourth year of her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
Benjamin Baillie, Her especial licence, full power, sole privilege and authority;
that I, the said Benjamin Baillie, my exors, admors, and assigns, or such
others as I, the said Benjamin Baillie, 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 THE FIXINGS OR
FASTENINGS THERETO BELONGING;" in which said Letters Patent is contained a
proviso that I, the said Benjamin Baillie, 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
Benjamin Baillie, do hereby declare the nature of my Invention, and the

page_text: 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 Drawing hereunto annexed, and to the figures and letters marked thereon
(that is to say):
In constructing rim locks for doors and for such like purposes it is usual
to pass the screws for fixing the same passed through the locks; and such was
the case in respect to the box staple used therewith. Now the object of the
Invention is a mode of constructing the rim locks and their fixings and
fastenings in such manner as to dispense with the screws passing through such
locks and the box staples. And my Invention also relates to a mode of
And in order that my Invention may

readily understood, I will proceed to describe the Drawing hereunto annexed,
and the figures and letters marked thereon.
DESCRIPTION OF THE DRAWING.
be
Fig. 1, exterior view of an improved rim or case lock and box staple, as it
appears when the door is shut, shewing all the projecting angles rounded off to
prevent damage to dresses; but this is not necessary if persons desire it other
wise. Figure 1, interior view, shews my method of stopping the bolt of latch
locks so as to use a temporary stoppage; also my method of constructing
locks and secure fixings. A is a moveable stop, which acts against a notch or
projection on the sector B, and prevents the bolt C being thrown back. When
the stop is not wanted it is pressed down against the stud E, and is kept stiff
by the under spring D. G is an angular stud or hook rivetted to the interior
of the lock, and slides into the plate staple I, which is provided with sharp
projections at the ends, to mark the place on the door, to facilitate the fixing of
it correctly. H, a side view or elevation of I.
Figure 2 shews my method of fixing a square rim or case lock by a stud
A, rivetted to the end of the rim, and fitting into a plate, staple, &c., or
square screw eye, B. The studs and eyes may be made round or other figure.
Figure 3 represents an improved street door lock with double lock C, which,
being used as represented, prevents the bolt from being thrown back, and if
pressed towards the stud D until it meets one of the teeth of the pinion B
will keep the bolt back out of use, and allow any other latch or lock to act
which may be on the same door. F is a section of a pinion B, with knob and
spindle.
Figure 4. A shews the face of an improved box staple of a lock (see
Figure 1 exterior). B, back view of the same, shewing the tenon E. C shews
an end view of the same, with a screw passed through the centre holes of

page_text: front plate and tenon. These can be of the shape shewn, or made of an
oblong square form, as indicated by dotted lines.
Figure 5. A is a common box staple with two studs E, E, rivetted into it.
B, plan of the same, shewing the rivets of the studs E, E. C, section of the
same, shewing a stud morticed into a door frame, through which a screw D
passes. F, G, perforated screws, which may be used to fix common box staples
instead of studs E, E. These may be made square and perforated, and may
have either rounded or flat heads, as shewn, and can be turned in and out of
wood by an awl or other pointed tool. I would remark that I do not confine
myself to any particular construction of the internal works of a lock, as they
may be varied.
Having thus described the nature of my Invention, I would have it under-
stood that I make no claim to any of the parts separately. But what I claim
is, the mode of constructing locks and their fixings or fastenings as herein
described, whereby the screws passing through locks and staples are dispensed
with. And I also claim the mode of applying a temporary stop to locks, as
herein explained.
In witness whereof, I, the said Benjamin Baillie, have hereunto set my
hand and seal, this Twenty-third day of June, in the year of our Lord
One thousand eight hundred and forty-one.
BENJAMIN (L.s.) BAILLIE.
