PROVISIONAL SPECIFICATION left by the said John Forster
Meakin at the Office of the Commissioners of Patents, with his
Petition, on the 2nd December 1875.
I, JOHN FORSTER MEAKIN, of No. 84, Baker Street, Portman Square,
do hereby declare the nature of the said Invention for "AN Improvement
IN SASH PULLIES BY WHICH THE AXLES CAN BE READILY OILED FROM THE FACE
PLATE WHILE FIXED IN THEIR PLACES IN THE FRAME," to be as follows:-
This Invention, which relates to the effectual oiling the axles of sash
and other pullies, has for its object to prevent the wear and tear of the

page_text: same, to enable them to run freely and noiselessly, and to enable oil to
be properly applied while the said pullies are fixed in their proper
places, and the sashes are hung without removal of any part or
parts..
The Invention consists in casting on either side of the frame a bush
in either iron, brass, or gun metal, and which unlike the present make
of bushes which circular reaches to the front plate, and is larger
and thicker than any hitherto made, and sufficiently thick to allow of
a small hole being bored through the face plate on either side of the
wheel obliquely down through the said bush to the root of the axle, the
said holes being trumpet mouthed, so that a small oil can may be easily
applied, and by gravitation the oil will be conducted to the required
spot. These holes may be covered by tappet screws to exclude dust, or
a separate face plate with only 2 tapped screws may be used to cover all
the 6 holes, 4 screw holes being always found in large pullies.
The present make of sash pulley has the axle flush with the bush, in
which case if it be fitted tight into the stile the wheel will not run freely.
To remedy this in this Invention the bush is made so thick as to be
nearly flush with the face plate on either side, while the axle does not
reach the outside of the bush by a thirty-second of an inch; if there-
fore the sash pulley be fitted into the pulley stile ever so tight the
wheel will be free to move.
The Invention is applicable to all pulley blocks, which may be so fixed
that the face plate is readily accessible.
SPECIFICATION in pursuance of the conditions of the Letters Patent, a
filed by the said John Forster Meakin in the Great Seal Patent
Office on the 30th May 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
FORSTER MEAKIN, of No. 84, Baker Street, Portman Square, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Second day of December, in the
g

page_text: year of our Lord One thousand eight hundred and seventy-five, in
the thirty-ninth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said John Forster Meakin,
Her special licence, that I, the said John Forster Meakin, my
executors, administrators, and assigns, or such others as I, the said
John Forster Meakin, 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 law-
fully 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 IMPROVEMENT IN SASH PULLIES BY WHICH THE AXLES
CAN BE READILY OILED FROM THE FACE PLATE WHILE FIXED IN THEIR PLACES IN
THE FRAME," upon the condition (amongst others) that I, the said John
Forster Meakin, 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 Forster Meakin, do hereby
declare the nature of my said Invention, and in what manner
the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
The object of this Invention is to provide by improved arrangements
for the axle of the sash pulley being always free from being jammed or
bound against the stile or window frame, and also to fully provide for
the effectual oiling the axles of sash pulleys, so as to prevent the wear
and tear of the same, and enable them to run freely and noiselessly,
and to enable oil to be properly applied while the said pulleys are fixed
in their proper places, and the sashes are hung without removal of any
part or parts.
To carry this Invention into effect I usually prefer to adopt the
following arrangements :-I cast or secure on either side of the frame a
bush or bearing in either iron, brass, or gun metal, and which, unlike
the present make of bushes, which are nearly always circular, reaches
to the front plate, and is larger and thicker than any hitherto made, and

page_text: sufficiently thick to allow of a small hole being bored through said
bushes, and the face plate on either side of the wheel obliquely down
through the said bush to the root of the axle, the said holes being
trumpet mouthed, so that a small oil can or other vehicle may be
easily applied, and the oil will travel to the required spot. These holes
may be covered by tapped screws to exclude dust, or a separate face
plate with only two tapped screws may be used to cover all the six
holes, four screw holes being nearly always found in large pulleys.
The present make of sash pulley has the axle flush with the bush, in
which case if it be tightly fitted into the stile, the wheel will not run
freely. To remedy this I make the bush so thick as to be nearly flush
with the face plate on either side, while the axle does not reach the out-
side of the bush by a thirty-second of an inch at least; if therefore the
sash pulley be fitted into the pulley stile ever so tight the wheel will be
free to move.
The Invention is applicable to all pulleys of the sash kind, which may
be so fixed that the face plate is readily accessible.

page_text: less in extent as to prevent the end being bound or jammed, as before
referred to.
In witness whereof, I, the said John Forster Meakin, have here-
unto set my hand and seal, this Twenty-sixth day of May, in
the year of our Lord One thousand eight hundred and seventy-
six.
