Year: 1861

page_text: LETTERS PATENT to Robert Smith; of Weymouth Cottage, Hornsey, Ben-
jamin Brooks, of 2, Albert Terrace, York Road, King's Cross, and James
Smith, of 2, Oak Villas, Wood Green, Tottenham, all in the County of
Middlesex, Builders, for the Invention of "IMPROVEMENTS IN THE CON-
PROVISIONAL SPECIFICATION left by the said Robert Smith, Benjamin
Brooks, and James Smith at the Office of the Commissioners of Patents,
with their Petition, on the 18th September 1861.
We, ROBERT SMITH, of Weymouth Cottage, Hornsey, BENJAMIN BROOKS, of
2, Albert Terrace, York Road, King's Cross, and JAMES SMITH, of 2, Oak
Villas, Wood Green, Tottenham, all in the County of Middlesex, Builders, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE CONSTRUCTION OF ROOF AND OTHER LIGHTS," to be as follows:-
As the frames of roof lights are at present formed, when the putty cracks
or separates either from the glass or frame, so as to admit water that water
may fall at once on to and injure objects beneath them.
The object of the improvements is to remedy this evil, and for this purpose,
we form the bars and other parts where they support the glass, with longi-
tudinal recesses or gutters. The edges of the glass lie over these parts, and
are then retained by putty in the usual way, or by other suitable holding means,
but when from any cause the holding means admits water through it, such
water after passing under the edges of the glass, in place of dropping at once,
will be received into the longitudinal recesses or gutters, and by them con-
ducted to suitable channels or receivers.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Robert Smith, Benjamin Brooks, and James Smith, in the
Great Seal Patent Office on the 12th March 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ROBERT
SMITH, of Weymouth Cottage, Hornsey, BENJAMIN BROOKS, of 2, Albert
Terrace, York Road, King's Cross, and JAMES SMITH, of 2, Oak Villas, Wood
Green, Tottenham, all in the County of Middlesex, Builders, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of September in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fifth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Robert Smith, Benjamin Brooks, and James Smith, Her special licence that
we, the said Robert Smith, Benjamin Brooks, and James Smith, our exe-
cutors, administrators, and assigns, or such others as we, the said Robert
Smith, Benjamin Brooks, and James. Smith, our 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 "IMPROVEMENTS IN THE CONSTRUCTION OF ROOF AND OTHER LIGHTS,"
upon the condition (amongst others) that we, the said Robert Smith, Ben-
jamin Brooks, and James Smith, our executors or administrators, by an instru-
ment in writing under our or their hands and seals, or under the land and
scal of one of us or 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 Offico within
six calendar months next and immediately after the dato of the said Letters
Patent.
NOW KNOW YE, that we, the said Robert Smith, Benjamin Brooks, and
James, Smith, do hereby declare the nature of the said Invention, and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement thereof, that is to say :-
As the frames of roof lights are at present formed, when the putty used to
secure the glass to the frame cracks or separates either from the glass or
frame so as to admit water, that water may fall at onco, on to and injure
objects beneath them.
The object of the improvements is to remedy this evil, and for this purpose
we form the bars and other parts where they support the glass with longi-

page_text: glass is then retained by putty in the usual way, or by other suitable holding
means. When from any cause the putty or other holding means admits
water through it, such water after passing under the edges of the glass, in
place of dropping at once therefrom, will be received into the longitudinal
recesses or gutters, and by them may conducted to suitable channels or
receivers.
But that the nature of the Invention, and means which we adopt in
carrying the same into effect may be fully understood, we will proceed to
describe the Drawing annexed.
DESCRIPTION OF THE DRAWING.
The Drawing shows several sections of different forms of frames adapted
to various purposes as roof lights. These forms are, however, only given as
examples, which are capable of still further modification. In each case there
is a groove a extending longitudinally of that part of the frame upon which
the edge of the glass rests, whilst the glass is supported by the part 6; c, re-
presents putty or other holding means applied to retain the glass d in its
position.
When from accidental or other cause, the putty or other holding means c
is cracked or deranged so as to admit water through, that water will be
received into the groove a, which, by communicating with a suitable gutter or
channel, will conduct such water away in place of allowing it to fall at once
on to whatever may be beneath the frame.
Having thus described the nature of the said Invention, and the means
which we find to answer in carrying the same into effect, we would have
it understood that what we claim is, the formation of roof and other lights with
grooves or channels under the glass for the purpose explained.
In witness whereof, we, the said Robert Smith, Benjamin Brooks, and
James Smith, have hereunto set our hands and seals, this Twelfth
day of March, in the year of our Lord One thousand eight hundred
and sixty-two.
