PROVISIONAL SPECIFICATION felt by the said George Ingram.at the
Office of the Commissioners of Patents, with his Petition, on the

I, GEORGE INGRAM, of 37, Marylebone Road, Parish of Saint Mary-
lebone, County of Middlesex, Clerk, do hereby declare the nature of the
said Invention for "IMPROVED APPARATUS FOR REGULATING THE LIFT OF RAILWAY
AND OTHER CARRIAGE WINDOWS," to be as follows :-
On the inside of the window runs or guides I fix two racks, one on
each side, formed of metal or other suitable material. On the window
frame near the top end, and on the inside, I fit a small rotating.rod with
cambs; at each end of the said. rod I fix a bracket formed of brass or
other suitable material, and in the said brackets the said rod rotates,, and

page_text: these brackets also serve as a guide for the window in its movement
up or down. To the centre of the rod before named I fix finger lifts in
such a manner that the action of the fingers shall rotate the rod and
so release the cambs from the racks. Under each camb I fix a spring,
one end of which is screwed to the window frame, the other end of the
spring acts on the back of the camb and thereby regulates the lift of
the window frame.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Ingram in the Great Seal Patent Office on
the 4th November 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
INGRAM, of 37, Marylebone Road, Parish of Saint Marylebone, County
of Middlesex, Clerk, send grecting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifth day of May, in the year of our
Lord One thousand eight hundred and seventy, in the thirty-third
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said George Ingram, Her special licence that I, the
said George. Ingram, my executors, administrators, and assigns, or such
others as I, the said George Ingram, 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 "IMPROVED APPARATUS FOR REGULATING
THE LIFT OF RAILWAY AND OTHER CARRIAGE WINDOWS," upon the condition
(amongst others) that I, the said George Ingram, 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 George Ingram, do hereby declare
'the nature of my said Invention, and in what manner the same

page_text: means the window may be raised or lowered as required, but when the
said springs ff, are allowed to act the frame is pressed against the
fence rail as aforesaid, thereby holding the window in suspension in
any position. The tips of the cambs c, c, and the tips of the springs f, f,
may be fitted with small rollers to reduce the friction.
Figs. 5 and 6 represent a spring. to act on the rod a behind the centre
bracket b.
Having thus particularly described and ascertained the nature and
object of my said Invention, and explained and illustrated the means I
propose to employ in carrying the said improvements into effect in
practice, I hereby further declare that I do not absolutely restrict myself
to the precise forms and arrangements of the several parts shown upon
the said Drawing, as these may be modified without departing from the
principles thereby illustrated, and upon which the said improvements
are based.
In witness whereof, I, the said George Ingram, have hereunto
set my hand and seal, this First day of November, in the
year of our Lord One thousand eight hundred and seventy.
