Year: 1826

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
LOACH, of Birmingham, in the County of Warwick, Brass Founder, send
greeting.
WHEREAS His present Majesty King George the Fourth, in and by His.
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Twenty-third day of May, now last, for Himself, His heirs and:
successors, did give and grant unto me, the said John Loach, my exors,
adñiors, and assigns, His especial license, full power, sole privilege and
.authority, that I, the said John Loach, my exors, adiñors, and assigns, and
every of them, by myself and themselves, or by my and their deputy or
deputies, servants or agents, or such others as I, the said John Loach, my
exors, adiñors, 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 my
Invention of "A SELF-ACTING SASH FASTENER, WHICH FASTENING IS APPLICABLE
TO OTHER PURPOSES," within that part of the United Kingdom, of Great Britain
and Ireland called England, the Dominion of Wales, and Town of Berwick-
upon-Tweed; in which said Letters Patent there is contained a. proviso,
obliging me, the said John Loach, by an instrument in writing under my
hand and seal, particularly to describe and ascertain the nature of my said
Invention, and in what manner the same is to be performed, and to cause
the same to be inrolled in His Majesty's High Court of Chancery within

page_text: six calendar months next and immediately after the date of the said recited
Letters Patent, as in and by the same, reference being thereunto had, will
more fully appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
John Loach, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, and particularly described
and ascertained in manner following (that is to say) :-
The nature of my said Invention, and the object of the same, is the
production and application of a certain self-acting fastening for sash windows,
and other articles acting on the same principles, and I do declare that I
perform the same according to the following particular description, having
reference to the several Figures or Drawings which shew the different
parts of my said Invention, and my methods of applying them (that is to
say)
Figure number 1 is a geometrical front view of the plate of the fastening,
having a hole through it A, through which hole I project a bolt or catch
B, as seen in Figure number 2, by means of a spring C, C, shewn in Figure
number 7, which is a side view of Figure number 2; or, I sometimes make it
without a spring to act with a joint, or swivel, or overbalance, to cause the
said bolt or catch to project through the said plate. On the back of the said
plate, Figure number 7, I make a projection D, D, D, on which I fix pius or
wards E, E, E, on which pins or wards I intend the key, Figure number 8, to
work, for the purpose of throwing back the spring C, C, to bring the projecting
bolt or catch B (attached to it) level with the front of the plate. Figure
number 3 is a striking plate, having any number of holes in it, as H, H, H,
made to receive through it the bolt or catch B in Figure number 7. Figures
number 4 and 5 are single striking plates, and are used either one or more, as
required. Figure number 6 is a rack, used for the same purpose as Figure
number 3, and made to receive into it the projecting bolt or catch B, in
Figure number 7, at certain distances marked S, S, S, S, S, S, S. I then
take Figure number 7, and fix it flush or level into the style of the sash or
sash frame, and cut a hole from the front of the sash or frame to the projection
D, D, D, on the back of the plate, through which I introduce the key,
Figure number 8, to act upon the pins or wards E, E, E, to throw back the
spring C, C, and bolt or catch B level with the front of the plate. I then take
Figure number 3, or one or more of Figures number 4 and 5, or Figure
number 6, and let it flush or level into the style of the sash or sash frame
opposite to Figure number 7, taking care that the projecting bolt or catch,
when the sash is closed, fits into the uppermost hole in Figure 3, or the

page_text: uppermost step in Figure number.6. And I do declare by these means I
produce a self-acting fastening which fastens window sashes or other articles
acting on the same principles, not only when closed but when opened at
any height, according to the length of Figures number 3, or number 6, or
such other length as may be required. Figure number 9 is a plate and catch
used for the same purpose as Figure number 7, but differing in its construction
by having a lever L, E, attached to the bolt or catch B joined to the back of
the plate at A; the spring marked C always pressing against the end of the
lever E throws down the other other end L and keeps the bolt or catch B
always projecting through the plate. The key, Figure number 8, is likewise
used with this article, and acting on the pins or wards P, P, presses down the
end of the lever E and the spring C, and throws up the opposite end of the
lever L, bringing the bolt B level with the front of the plate while the sashes
and so forth are opened. Figure number 10 is a plate and catch made
to act without a key, by means of a slide, Figure number 11, and is let
flush or level into the stile of the sash or sash frame, as before described in
Figure number 7. I then cut a hole from the front of the sash or frame to
the back of the plate, and let on the slide, Figure number 11, introducing the
wire A through the hole in the swivel marked H in Figure number 10; and
by pulling the slide S, I produce the same action on the bolt or catch B,
as before described by means of the key in Figure number 9. Figure 13
is a self-acting fastening, made to fasten two sashes or other perpendicular
sliding articles with one action, in which, A, A, shews the plate, having the
screw holes in it; B, B, B, the frame attached to the plate which contains
the bolt C, C, the dotted lines of which mark its form and situation in the
frame, being jointed to it at D; the spring F, F, F, acting under the leg of
the bolt C, C, keeps it always projecting forward. The dotted lines marked
S, S, shew the screw which I sometimes use for greater security, which,
passing through the back of the frame B, B, B, presses, by means of the key,
Figure number 12. against the bolt C, C, and renders it impossible to force
it back without the aid of the key. I then take Figure number 13, and fix
it on the right or left hand corner of the top rail of the bottom saslı, or one
on each corner if necessary, so that the front of the bolt may strike against
the front of the stile of the uppermost sash. I then fix one or more of the
striking plates, Figure number 14, on the front of the stile of the upper sash,
so that when the sashes are closed, the bolt C, C, strikes into the lowermost
striking plate on the upper sash. And for greater security, by turning up the
screw S, S, by means of the key, Figure number 12, I press the bolt firmly
against the striking plate opposite, and render the window perfectly safe, not

page_text: only when closed but when opened at any height, according to the number of
striking plates on the upper sash. Figure number 15 shews the frame of the
fastening B, B, B, without the bolt; Figure number 16 shews the bolt C, C,
without the frame; and Figure 16, the screw S, S. And I do declare by
these means I produce a self-acting
self-acting fastening which fastens two sashes or
other perpendicular sliding articles with one action.
And I further declare that I make my said Invention, and each and every
part of the same, of copper, brass, iron, steel, or mixed metals of any
⚫dimensions.
In witness whereof, I, the said John Loach, have hereunto set my
hand and seal, this Twenty-first day of 'November, in the year of our
Lord One thousand eight hundred and twenty-six.
