PROVISIONAL SPECIFICATION.
Improvements in Self-lubricating Pulleys for Window-sashes and
the like.
GEORGE HURDLE 3 Adelaide Road St. Denys Southampton do hereby declare the
nature of this invention to be as follows:-
-
The invention has for its object the simple construction and arrangement of a
pulley and its bearing which may be attached or detached from the pulley style of
a window or other suitable position in which the device may be placed as desired
also the automatic lubrication of the same and is carried out in the following
manner.
I provide a suitable metal casing which contains recesses for the reception of the
lubricating material and the bearings for the wheels or pulleys. I may if desired
cast or form this said casing into one piece or I may form it in two or more pieces.
This casing I prefer to form in the shape of a cylinder which has been flatened
on two of its opposite sides. One of these flatened sides forms the top of the
cylinder or casing. At one end of this cylinder or casing a flange is formed with
an apeture for the passage of the rope or cord. This casing is cored or slotted
out so as to formn bearings for the main pulley and guide pulley, at the same time
a channel or recess is formed under the bearings for the reception of oil or other
lubricating material a piece of cotton or other suitable material is placed around
or in contact with the pulley spindle or axle and allowed to reamain in contact
with the oil or other lubricant. Suitable lids or flaps are provided for the purpose
of excluding dust from the bearings.
It will be seen that if a suitable hole is cut in the pulley style slightly rebated
or countersunk on its edge to admit the flange on the end of the casing entering
same while the diameter of the hole allows the cylinder to be driven in into the
apeture & thus be securely held in position and a limit of a rope passing over the
main pulley one end being attached to the sash frame while the other is attached
to the weight or counterpoise. This arrangement facilitates the ready fixing and
access to the pulleys. If desired the pulley wheels may be covered with any
suitable material so as to decrease the wear and tear upon the ropes through friction.

GEORGE HURDLE 33 Adelaide Road Saint Denys Southampton Engineer &c. do
hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
This invention has for its object the simple construction and arrangement of a
pulley and its bearings which may be attached or detached from the pulley style of a
window or other suitable position in which the device may be placed as desired also
the automatic lubrication of the same and is carried out in the following manner.
I provide a suitable metal casing which contains recesses for the reception of the
lubricating material and the bearings for the wheels or pulleys. I may if desired cast
or form this said casing in one piece or I may form it in two or more pieces. This
casing I prefer to form in the shape of a cylinder which has been flattened on two of

At one end of this cylinder or casing a flange is formed with an aperture for the
passage of the rope or cord. This casing is cored or slotted out so as to form
bearings for the main pulley and guide pulley at the same time a channel or recess is
formed under the hearings for the reception of oil or other lubricating material; a
piece of cotton or other suitable material is placed around or in contact with the
pulley spindle or axle and allowed to remain in contact with the oil or other lubricant.
Suitable lids or flaps are provided for the purpose of excluding dust from the
bearings.
It will be seen that if a suitable hole is cut in the pulley style slightly rebated or
countersunk on its edge to admit the flange on the end of the casing entering same
while the diameter of the hole allows the cylinder to be driven into position and
securely held, and allows the rope to pass over the main pulley one end being attached
to the sash frame while the other is attached to the weight or counterpoise, this
arrangement facilitates the ready fix
access to the pulleys. If desired the
pulley wheels may be covered with a itable material so as to decrease the wear
and tear upon the ropes through frictio

Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim and desire to secure by Letters Patent is

recesses e e the sides of which support the pulleys d. d at c. c and contains any suitable
lubricant covered by removeable lids or flaps f. f.
(2) In pulleys for windows and the like the receptacles e. e covered by the lids or
flaps f. f. for containing any suitable lubricant.
(3) In pulleys for windows and the like the removeable lids or flaps f. f. which
when removed allow the pulley wheels to be easily removed from the bearings.
(4) The general arrangements of the parts forming the pulley substantially as
described and for the purpose set forth.
