Year: 1863

page_text: LETTERS PATENT to Mark Hillary, of Andover, in the County of
Hants, Contractor, for the Invention of "IMPROVEMENTS IN FASTENINGS
FOR DOORS."
Sealed the 3rd June 1864, and dated the 9th December 1863.
PROVISIONAL SPECIFICATION left by the said Mark Hillary at the
Office of the Commissioners of Patents, with his Petition, on the 9th
December 1863.
I, MARK HILLARY, of Andover, in the County of Hants, Contractor, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
FASTENINGS FOR DOORS," to be as follows:-
This Invention relates to a peculiar construction and arrangement of lock
or fastening for stable and other doors, whereby greater security against the
opening of the door by horses and cattle is obtained, combined with strength
and simplicity.
According to this Invention it is proposed to employ a bolt which slides
horizontally, and has a rising and falling motion at its inner end, which
is contained within a strong lock case or box. The under side of the bolt
has two notches formed therein which rest upon a stationary pin passing
transversely through the lock case and through the door. The bolt is held
down upon the pin by a spring, and in order to afford facility for shooting or
withdrawing the bolt a finger hole is made therein, or a projecting stud may.
be fitted thereon, such finger hole or stud coinciding with a curved slot or

page_text: opening made in the front and back lock plates. In moving the bolt in or
out the finger is inserted into the hole in the bolt, and the rear end of the
same is lifted slightly so as to disengage one of the notches from the stationary
pin, when the bolt may be slid outwards or inwards, as desired, and will then
lock or fix itself by bringing the second notch on to the pin, the bolt being
locked or fixed in both positions. If desired, an additional bolt or catch may
be fitted inside the lock acted upon by a key whereby the main bolt may be
locked or fixed in its place, so as not to be capable of being opened by the
finger until it has been released or freed by the key.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Mark Hillary in the Great Seal Patent Office on the
9th June 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MARK
HILLARY, of Andover, in the County of Hants, Contractor, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of December, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-seventh year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Mark Hillary, Her special license that I, the said Mark
Hillary, my executors, administrators, and assigns, or such others as I, the
said Mark Hillary, my executors, administrators, or 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 lawfully 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 "IMPROVE-
MENTS IN FASTENINGS FOR DOORS," upon the condition (amongst others) that
I, the said Mark Hillary, my executors or administrators, by an instru-
ment in writing under my hand and seal, or under the hand and seal of
one of them, 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 Mark Hillary, 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

page_text: statement, reference being had to the accompanying Drawings, and to the
letters and figures marked thereon, that is to say:—
My said Invention relates to a peculiar construction and arrangement of
lock or fastening for stable and other doors, whereby greater security against
the opening of the door by horses and cattle is obtained, combined with strength
and simplicity.
According to this Invention, it is proposed to employ a bolt which slides
horizontally, and has a rising and falling motion at its inner end which is
contained within a strong lock case or box. The under side of the bolt has
two notches formed therein which rest upon a stationary pin passing trans-
versely through the lock case, and in some cases through the door also. The
bolt is held down upon this pin by a spring, and in order to afford facility for
shooting or withdrawing the bolt a finger hole is made therein, or a projecting
stud may be fitted thereon, such finger hole or stud coinciding with a curved
slot or opening made in the front and back lock plates. In moving the bolt
in or out the finger is inserted into the hole in the bolt, and the rear end of
the same is lifted slightly so as to disengage one of the notches from the
stationary pin, when the bolt may be slid outwards or inwards as desired, and
will then lock or fix itself by bringing the second notch on to the pin, the bolt
being locked or fixed in both positions. If desired, an additional bolt or
catch may be fitted inside the lock acted upon by a key, whereby the main
bolt may be locked or fixed in its place, so as not to be capable of being opened
by the finger until it has been released or freed by the key.
And in order that my said Invention may be fully understood, I shall
now proceed more particularly to describe the same, and for that purpose
I shall refer to the several Figures on the Sheet of Drawings hereunto
annexed, the same letters of reference indicating corresponding parts in all
the Figures.
Fig. 1 of my Drawings represents a side elevation of my improved door
fastening with one of the lock plates removed, which plate is shewn in side
elevation at Figure 2.
A is the box or casing of the lock or fastening through which extends from
one side.plate B to the other a stationary pin or bar C; D is the bolt, which
has two notches E, E¹, formed on the under side or edge thereof, such notches
being made to fit on to the pin C, which thus holds the bolt secure, and
prevents it from being shot back by pressing against the end thereof. A
finger hole F, or a slightly projecting knob, is formed in or attached to the
bolt, such hole or knob coinciding with a slot or opening G made in one or
both the lock plates B. The object of this finger hole or knob is to afford

page_text: facility for moving the bolt in or out as required, by simply inserting the
finger into the hole, or taking hold of the knob and lifting the rear part of
the bolt upwards so as to clear the notch from the pin C, and then pushing
the bolt outwards or inwards according as the door is to be locked or unlocked,
when the bolt is permitted to drop again, bringing the second notch on to the
pin C, which will hold it securely till it is again released, as before. The
dotted lines in Figure 1 show the position of the bolt when shot out or locked.
If preferred, a spring H may be employed for holding the bolt firmly down
upon the pin C, as shown in the modification, Figure 3, of which Figure 4 is
the front lock plate detached. In some cases I propose to adopt a small
supplementary lock I (Figure 3) of any good and well-known construction
to the interior of the box or casing A, and to make a corresponding key-
hole K (Figure 4) in the lock plates B, whereby the bolt or bolts L (shown
in dotted lines) may be shot out or in by any ordinary key. The object of
this supplementary lock is to secure the main bolt D when shot out, as shown
by the dotted lines in Figure 3. For this purpose I fit a small projection M
on the upper side of the bolt D, the top of such projection when the bolt Dis
shot out or locked coming exactly under the bolt L of, the supplementary
lock I, and consequently the main bolt D cannot be raised or released from
the holding pin C, and cannot therefore be moved in any way until the bolt
of the supplementary lock has been withdrawn. It is obvious that various,
arrangements of supplementary locks or catches may be employed for securing
the bolt D; for example, the supplementary lock may be turned in such a
position that its bolt will press directly downwards upon the top of the main
bolt D, in which case the projection M would be dispensed with, or a swivel,
button, or catch, as shown at L (Figure 5), might be employed in lieu of a
lock, such button or catch being turned so as to, secure or release, the, bolt D.
by means of a hollow key fitting on to a square shank on the axis of the
button, or by a square key fitting a hollow in the button. The full lines shew
the position of the button when the bolt D is secured, and the dotted lines its
position when turned by the key in order to release the bolt.
Having now, described and particularly ascertained the nature of my said
Invention, and the manner in which the same is or may be used or carried into
effect, I would observe in conclusion that what I consider to be novel and
original, and therefore claim as the Invention secured to me by the, herein-
before in part recited Letters Patent, is,-
First, the combination of a sliding bolt provided with a finger, hole or knob
and two,notches with a lock case or box, provided with. a. pin or. bar which fits
into one or other of the two notches in the bolt, having slots or openings

page_text: in one or both the lock plates coinciding with the finger hole or knob of the
bolt, substantially as herein-before described.
Second, the combination with a fastening of the construction herein-before
described and illustrated by Figure 1 of the Drawings, of a spring for holding
down the bolt, and keeping the notches down upon the holding pin or bar in
the lock case.
Third, the application and use to and in locks or fastenings of the
description herein-before referred to, of a supplementary lock or additional
bolt or catch acted upon by a key for securing or fixing the main bolt,
substantially as herein-before described.
In witness whereof, I, the said Mark Hillary, have hereunto set my
hand and seal, this Seventh day of June, in the year of our Lord One
thousand eight hundred and sixty-four.
MARK HILLARY. (L.B.)
