Year: 1866

page_text: LETTERS PATENT to John Henry Roberts, of Camberwell, in the County
of Surrey, Gentleman, for the Invention of "A NEW OR IMPROVED
FASTENING FOR WINDOWS AND OTHER PLACES."
Sealed the 5th April 1867, and dated the 8th October 1866.
PROVISIONAL SPECIFICATION left by the said John Henry Roberts at
the Office of the Commissioners of Patents, with his Petition, on the
8th October 1866.
I, JOHN HENRY ROBERTS, of Camberwell, in the County of Surrey,
Gentleman, do hereby declare the nature of the said Invention for "A NEW
OR IMPROVED FASTENING FOR WINDOWS AND OTHER PLACES," to be as follows:-
My Invention consists of a new or improved fastening particularly intended
for securing window sashes, but also applicable where fastenings are employed
for other purposes.
I proceed to describe my Invention as applied to window sashes. Upon
one sash, say the outer, I secure a plate formed with a slot, in which a button
or stud is free to move backwards and forwards. Upon the other sash I secure
another plate, which has a third plate hinged thereto, the hinged, plate being
capable of moving so as to come upon the first-named plate; this hinged plate
is likewise formed with a slot corresponding to the first-named slot and
terminating at one end in a circular or enlarged aperture corresponding to
the button or stud. To secure the fastening bring the hinged plate on the

page_text: inner sash upon the plate on the outer sash, so that the button enters the
circular or enlarged aperture; then push the button along the slots, and
the fastening is secure. To release the fastening make the reverse movements.
The slots in the plates may be formed in any direction desired. Sometimes I
form a thumb-piece or projection on the hinged plate for convenience of
moving it.
SPECIFICATION in pursuance of the conditions of the Letters Patent, file
by the said John Henry Roberts in the Great Seal Patent Office or
the 8th April 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
HENRY ROBERTS, of Camberwell, in the County of Surrey, Gentleman, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of October, in the year of our Lord
One thousand eight hundred and sixty-six, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said John Henry Roberts, Her special licence that I, the said John
Henry Roberts, my executors, administrators, and assigns, or such others as
I, the said John Henry Roberts, my executors, administrators, and 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
"A NEW OR IMPROVED FASTENING FOR WINDOWS AND OTHER PLACES," upon the
condition (amongst others) that I, the said John Henry Roberts, my executors
or administrators, by an instrument in writing under my, or their, or one of
their hands and seals, 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 John Henry Roberts, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, reference being had to the Drawings hereunto annexed, that
is to say:
My Invention consists of a new or improved fastening particularly intended

page_text: for securing window sashes, but also applicable where fastenings are employed
for other purposes.
I proceed to describe my Invention as applied to window sashes. Upon
one sash, say the outer, I secure a plate formed with a slot, in which a button
or stud is free to move backwards and forwards. Upon the other sash I
secure another plate, which has a third plate hinged thereto, the hinged plate
being capable of moving so as to come upon the first-named plate; this hinged
plate is likewise formed with a slot corresponding to the first-named slot and
terminating at one end in a circular or enlarged aperture corresponding to
the button or stud. To secure the fastening bring the hinged plate on the
inner sash upon the plate on the outer sash, so that the button enters the
circular or enlarged aperture, then push the button along the slots and
the fastening is secure. To release the fastening make the reverse movements.
The slots in the plates may be formed in any direction desired. Sometimes
I form a thumb-piece or projection on the hinged plate for convenience of
moving it.
My Invention will be fully understood by the annexed Drawings.
a, Fig. 1, is the plate secured to the inner or front sash; b is the other
plate hinged to the plate a; tbis hinged plate is formed with a slot c terminating
at one end in an enlargement d; e is the plate screwed to the outer or back
sash; it is also formed with a slot f corresponding to the slot c; g is a button
free to move backwards and forwards in the slot f. To secure the fastening
the plate 6 is brought over the plate e, so that the button g enters the enlarge-
ment d. By then sliding the button into the position shown in Figure 4 the
fastening is secure. To open it the movement of the button is reversed, and.
the plate 6 is made to turn back flat on the sash, as in Figure 3; or by fitting
a stop the plate 6 can be made perpendicular, or nearly so, to indicate that the
window is unfastened; h is a projection for convenience in moving the
plate b.
A modification of this Invention is represented in Figure 5, in which I
employ an oblong button g; when the slot c is brought over the button, the
latter is moved in its slot, and then turned a quarter round, and the
fastening is secure.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim, constructing
fastenings for windows and other places, in which an aperture or slot in a
hinged plate, connected to one sash or portion of the object to be fastened, is
brought over a button or stud connected to the other sash or portion of the
object to be fastened, and the button or stud then moved to complete the

page_text: fastening, substantially as herein-before described and illustrated in the
accompanying Drawings.
In witness whereof, I, the said John Henry Roberts, have hereunto set
my hand and seal, this Sixth day of April, in the year of our Lord
One thousand eight hundred and sixty-seven.
J. HENRY ROBERTS. (L.S.)
