Year: 1865

page_text: LETTERS PATENT to John Pennington, of Muncaster Villa, Croxted
Road, Dulwich, in the County of Surrey, for the Invention of "IMPROVE
MENTS IN APPARATUS USED FOR OPENING AND CLOSING CARRIAGE AND OTHER
WINDOWS."
Sealed the 2nd March 1866, and dated the 9th September 1865.
PROVISIONAL SPECIFICATION left by the said John Pennington at the :
Office of the Commissioners of Patents, with his Petition, ou the 9th
September 1865.
I, JOHN PENNINGTON, of Muncaster Villa, Croxted Road, Dulwich, in the
County of Surrey, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN APPARATUS USED IN OPENING AND CLOSING CARRIAGE AND OTHER
WINDOWS," to be as follows:-
This Invention has for its object improvements in apparatus used in opening
and closing carriage and other windows. For these purposes two toothed racks
are used to each window, and the lower ends of these racks are pin-jointed or
otherwise attached or fixed to the lower end of the window. The racks move
between guides when the window is being opened or closed. Motionis com-
[Price 8d.]

page_text: municated to the two racks simultaneously by means of cog or toothed wheels
in the following manner:-On a shaft or axis is fixed a toothed wheel, which
actuates a cog wheel gearing with the teeth of one of the toothed racks. The
toothed wheel on the shaft or axis also gears with an intermediate wheel, and
this gears with another toothed wheel which gears with the other rack, hence
when the shaft or axis is turned round by means of a handle on a disc, or
on a suitable crank fixed to the shaft or axis, the racks and consequently the
window will be raised or lowered, and by friction it is caused to remain in
any position to which it is raised or lowered.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Pennington in the Great Seal Patent Office on the
9th March 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
PENNINGTON, of Muncaster Villa, Croxted Road, Dulwich, in the County of
Surrey, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of September, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-ninth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said John Pennington, Her special licence that I, the said John
Pennington, my executors, administrators, and assigns, or such others as I
the said John Pennington, 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 "IM
PROVEMENTS IN APPARATUS USED IN OPENING AND CLOSING CARRIAGE OR OTHER
WINDOWS," upon the condition (amongst others) that I, the said John Pen-
nington, 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 Pennington, do hereby declare
the nature of the said Invention, and in what manner the same is to be

page_text: performed, to be particularly described and ascertained in and by the following
statement thereof, that is to say :-
This Invention has for its object improvements in apparatus used in opening
and closing carriage and other windows. For these purposes two toothed
racks are used to each window, and the lower ends of these racks are pin-
jointed or otherwise attached or fixed to the lower end of the window. The
racks move between guides when the window is being opened or closed.
Motion is communicated to the two racks simultaneously by means of cog or
toothed wheels in the following manner:-On a shaft or axis is fixed a toothed
wheel which actuates a cog wheel gearing with the teeth of one of the toothed
racks. The toothed wheel on the shaft or axis also gears with an intermediate
wheel, and this gears with another toothed wheel which gears with the other
rack, hence, when the shaft or axis is turned round by means of a handle on
a disc, or on a suitable crank fixed to the shaft or axis, the racks and con-
sequently the window will be raised or lowered, and by friction it is caused to
remain in any position to which it is raised or lowered.
And in order that my Invention may be fully understood and readily carried
into effect, I have in the Drawings hereunto annexed shown a railway carriage
door, having applied to it apparatus such as is above described for raising and
lowering the window frame

page_text: other window frames, but I have only thought it necessary to shew it applied
to the window frame of a railway carriage door.
In witness whereof, I, the said John Pennington, have hereunto set
my hand and seal, this Seventh day of March, in the year of our Lord
One thousand eight hundred and sixty-six.
JOHN PENNINGTON. (L.S.)
