Improvements in Sash and like Pulleys.
WILLIAM JOHNSON Commission Agent 3 Royal Exchange Court Glasgow do
hereby declare the nature of this invention to be as follows:
This invention consists of certain improvements in sash, axle, or other pulleys
used for carrying cords or chains for raising or lowering sashes, lifts, and for other
purposes.
Instead of the face plate of an axle or other pulley being made in one piece as
usual, I make in two or more parts as may be found most desirable, in order that
one part of the face plate can readily be removed when the axle pulley is fixed in
position, and the sash hung to the sash weights, so that access may be got to the
interior of the axle pulley for cleaning or oiling and also for the more ready means
of replacing cords and chains.
In order that my invention may be fully understood, and carried into effect, I
will proceed to describe the drawings annexed.
Fig. 1 shows side elevation of axle pulley with the face plate made in two parts,
the bottom plate A which has a crank at the top, may be fixed permanently to the
pulley frame, or moveable if desired. The upper plate B at its bottom end is
slipped into the cranked recess of the bottom plate, and then secured at the top to
the pulley frame, by a thumb screw as drawn, or a plain screw, or any other
required means, as may be found desireable. The top of the upper plate is scalloped
outwards for the purpose of readily pulling out the upper plate when required, or
instead of the scalloped top, a stud or projection may be fixed to the plate for the
same purpose.
Fig. 2 shows front elevation of upper plate as shown fixed in Fig. 1 and Fig. 3.
Fig. 3 shows front elevation of pulley all as described above.
.
Fig. 4 shows side elevation of pulley with face plate made in two parts, but
hinged together, showing upper plate moved forward in order to get access to the
interior of the pulley. When the face plate is closed it is secured to the pulley
frame as described for Fig. 1.
Fig. 5 shows front elevation of Fig. 4 as described above.
I do not confine myself to the methods before described and drawn for fixing the
face plates to sash, axle and other pulleys, but claim to fix them in any way found
most suitable, and also to make the face plates of any shape or configuration.

COMPLETE SPECIFICATION.
Improvements in Sash and like Pulleys.
1 WILLIAM JOHNSON Commission Agent 3 Royal Exchange Court Glasgow
do hereby declare the nature of this invention and in what manner the saine is to
be performed, to be particularly described and ascertained in and by the following
statement:—
This invention which consists of certain improvements in sash, axle, and like
pulleys, has for its object, to provide for the efficient oiling and cleaning of the
axle and bearings of the pulleys, which will enable the wheels to revolve freely and
silently, also preventing undue wear on the axle and bearings. Oil can be poured

page_text: down the oblique channel from the front of the pulley to the axle bearings. Instead
of the face plates being made in one piece, and then rivetted or screwed to the
pulley frame in the usual manner, I make them in one or more parts, which may
be hinged together, and then fixed to the pulley frame, or fixed or hinged separately
to the pulley frame, as may be found most desirable, iu order that one part can be
readily opened when the pulley is fixed in its place, and the sash is hung, in order
to get access to the interior.
In order that my invention may be fully understood and carried into effect, I
will proceed to describe the drawings filed with my Provisional Specification.
Fig. 1 shows side elevation of pulley with face plate made in two parts. The
bottom plate A, which has a crank at the top, may be fixed permanently to the
pulley frame, or moveable. The upper plate B at its lower end, is slipped into
the cranked recess, at the top of the bottom plate A, and then secured at the top by
a screw to the pulley frame.
Fig. 3 shows front elevation of pulley all as described above.
Fig. 2 shows front elevation of the upper plate B as shown fixed in Fig. 1 and 3.
Fig. 4 shows side elevation of pulley with face plate made in two parts, but
hinged together, showing upper part of the face plate moved forward in order to
get access to the interior. When the face-plate is closed it is secured to the
pulley frame by an ordinary countersunk screw, or by a thumb screw as shown on
Fig. 1.
Fig. 5 shows front elevation of Fig. 4 all as described, but with face plate closed.
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 is―
1. In making the face plates of sash, axle, or like pulleys, in two or more parts,
which I fix separately as shown in drawings left with the Provisional Specification
Fig. 1. 2. 3 or in any other suitable manner.
2. In making the face plates of sash, axle or like pulleys in one or more parts,
which I hinge to the pulley frame or to the pulley style.
3. In making the face plates of sash, axle, or like pulleys in one or more parts,
which hinge together and then fix to the pulley frame, as shown on drawings
left with Provisional Specification Fig. 4. 5.
•
4. The general construction arrangement and combination of parts, substantially
as described and represented or any mere modification thereof.
