IMPROVEMENTS IN THE CONSTRUCTION OF SASH PULLEYS WHICH IMPROVEMENTS ARE ALSO APPLICABLE TO FLUSH BELL AND OTHER PULLEYS
Year: 1884

page_text: I WILLIAM JOHN PENNY of Southend in the County of Essex Builder and
Decorator do hereby declare the nature of my Invention for IMPROVEMENTS IN
THE CONSTRUCTION OF SASH PULLEYS WHICH IMPROVEMENTS ARE ALSO APPLICABLE
TO FLUSH BELL AND OTHER PULLEYS to be as follows:-
"
The object of my present invention is to afford a ready means for taking out the
pulley wheel from a sash or other pulley thereby greatly facilitating the effecting
of repairs when necessary.
To effect this I cast the pulley wheel with a short central spindle on which
I afterwards form two rims or shoulders-(one on each side)-by turning the
same.
.
I cast the face plate and pulley box in one taking care to form recessed apertures.
and bearings (one on each side of the box)—wherein the two arms of the pulley
spindle lodge and are supported.
--
The opening in the face plate wherein the pulley wheel is inserted is recessed to
a sufficient width to allow the arms of the pulley spindle to pass through and
drop down into the recessed apertures and bearings in the sides of the pulley box.
To provide for the ready removal of the pulley wheel I make a small hole in its
periphery and by inserting a bradawl or other pointed tool therein the pulley
spindle can be readily lifted over the recessed bearings in the pulley box and the
pulley wheel taken out.
My invention is at once simple and valuable-The saving of time labour and
trouble effected thereby can only be accurately estimated by those persons who are
practically acquainted with the great difficulty hitherto experienced in repairing
sash lines, bellpulls, and other similar fittings owing to the impossibility of readily
removing the pulley wheel from the pulley box.

page_text: I, WILLIAM JOHN PENNY of Southend in the County of Essex, Builder and
Decorator do hereby declare the nature of my invention for IMPROVEMENTS IN THE
CONSTRUCTION OF SASH PULLEYS WHICH IMPROVEMENTS ARE ALSO APPLICABLE
TO FLUSH BELL AND OTHER PULLEYS and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
The object of this invention is to afford a ready means for taking out the
pulley wheel from the pulley box thereby greatly facilitating the fitting and
repairing of sash and other pulleys.
Fig: 1 shews a side elevation and Fig: 2 a front elevation of my improved sash
pulley Fig 3 is a view in perspective.
•
To effect this I cast two short arms (1) forming a central spindle on the pulley
wheel each having a small collar (2) formed thereon These collars form stops to
keep the wheel in position in the pulley box-A detail view of one of such arms
is shewn at Fig 4.
I cast the face plate and pulley box either in one or in two parts and if the
latter I rivet or otherwise fasten the same together-On each side of the box
I form a recessed bearing (3) to' receive the arms of the pulley wheel when placed
therein A recess (4) is made on each side of the slot in the face plate to allow
such arms to pass through and drop down into the recessed bearings (3).
To. provide for the easy removal of the pulley wheel I make a small hole (5) in
its periphery and by inserting a bradawl or other pointed tool therein the pulley
spindle can be readily lifted over the recessed bearings in the sides of the pulley
box and the pulley wheel taken out.
My invention is at once simple and valuable owing to the saving of time labour
and trouble effected thereby when fitting or repairing sash lines bell pulls and
other similar fittings..
My improvements may be readily applied to flush bell and other pulleys-
Existing pulleys may also be readily altered so as to work in the manner above
described.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1° The improved construction of sash pulley substantially as hereinbefore
specified.
2° The application of the improved construction hereinbefore described to
flush-bell and other pulleys.
