PROVISIONAL SPECIFICATION left by the said Strother Price at the
Office of the Commissioners of Patents, with his Petition, on the 23rd.
November 1864.
I, STROTHER PRICE, of Highbury, in the County of Middlesex, Commercial
Traveller, do hereby declare the nature of the said Invention for "AN. IMPROVED
APPARATUS FOR LIFTING OR ASSISTING TO LIFT WINDOW SASHES AND OTHER LIKE
FRAMES," to be as follows:-
At present balance weights are employed to lift or assist in lifting window
sashes of the class known as "guillotine" sashes, and the object of my
Invention is to substitute for the weights an apparatus which, while producing
similar effects, avoids the inconveniences attendant upon the employment of
weights.
My apparatus consists of a spring barrel to which one end of the sash line,
band, cord, or chain is attached, while the other end is attached to the sash
frame and is carried over a pulley in the usual manner.
To every sash frame I apply two such apparatuses, one for each sash line.
As soon as the sash frame, supposing it to be the under, one, is commenced to
be raised, the springs come into play, lift or assist in lifting the sash,. and wind

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, STROTHER
PRICE, of Highbury, in the County of Middlesex, Commercial Traveller, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of November, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Strother Price, Her special licence that I, the said Strother
Price, my executors, administrators, and assigns, or such others as I, the
said Strother Price, 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 "AN
IMPROVED APPARATUS FOR LIFTING OR ASSISTING TO LIFT WINDOW SASHES AND
OTHER LIKE FRAMES," upon the condition (amongst others) that I, the said
Strother Price, 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 Strother Price, do hereby declare
the nature of my 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, reference being had to the Drawings hereunto annexed, that
is to say:
At present balance weights are employed to lift or assist in lifting window
sashes of the class known as "guillotine" sashes, and the object of my Inven-
tion is to substitute for the weights an apparatus, which, while producing
similar effects, avoids the inconveniences attendant upon the employment of
weights.

page_text: My apparatus consists of a spring barrel to which one end of the sash line,
band, cord, or chain is attached, while the other end is attached to the sash
frame and is carried over a pulley in the usual manner.
To every sash frame I apply two such apparatuses, one for each sash line.
As soon as the sash frame, supposing it to be the under one, is commenced to
be raised, the springs come into play, lift or assist in lifting the sash, and wind
the sash lines upon the barrels. The apparatus is applicable to other
frames as well as window sashes which have an up-and-down movement.
frame as shown. The
Figure 1 of the accompanying Drawings is a view of the inside of a window
with my apparatus applied so as to lift or assist in lifting the lower sash.
A, A, are two spring barrels fitted one on each side of the upper part of the
frame; B, B, are bands, one end of each of which is attached to one of the
barrels A, while the other end is attached to the sash
spring barrel I employ is represented in section in Figure 2, and in
elevation in Figure 3. The end of the band B is secured to the barrel by a
stud C on the band entering a slot made for the purpose in the barrel. The
other end of the band also carries a stud D, which enters a similar slot in a
plate fitted to the sash frame. To fix the sash at any required height I fit on
the front of the sash a spring bolt, shown detached in Figure 4, which takes
into one or other of the slots in a slotted plate, Figure 5, fitted to the window
frame. In some cases instead of the spring bolt and slotted plate I form
ratchet teeth or fit a ratchet wheel on one side of each barrel, and fit a spring
paul on the window frame to take into the ratchet teeth.
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
apparatus for lifting or assisting to lift window sashes and other like frames
substantially as herein-before described and represented in the accompanying
Drawings.
In witness whereof, I, the said Strother Price, have hereunto set my
hand and seal, this Twenty-third day of May, One thousand eight
hundred and sixty-five.
STROTHER PRICE. (L.S.)
