IMPROVEMENTS IN PULLEYS FOR SUSPENDING WINDOW FRAMES, AND FOR OTHER LIKE PURPOSES
Year: 1867

page_text: LETTERS PATENT to Frederick Ryland, of West Bromwich, in the County
of Stafford, Ironfounder, for the Invention of "IMPROVEMENTS IN PULLEYS
FOR SUSPENDING WINDOW FRAMES, AND FOR OTHER LIKE PURPOSES."
Sealed the 3rd January 1868, and dated the 6th August 1867.
PROVISIONAL SPECIFICATION left by the said Frederick Ryland at the
Office of the Commissioners of Patents, with his Petition, on the 6th
August 1867.
I, FREDERICK RYLAND, of West Bromwich, in the County of Stafford,
Ironfounder, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN PULLEYS FOR SUSPENDING WINDOW FRAMES, AND FOR
PURPOSES," to be as follows:
My Invention consists of the following improvements in that part of
pulleys for suspending window frames, and for other like purposes, called the
mortise plate. I make the said mortise plate with semicircular ends, and .I
make in the centres of the said semicircular ends the holes through which the
screws are passed to secure the mortise plate in the mortise of the window
frame or other article; I also make the opening in the mortise plate in which
the bowl or wheel of the pulley works with semicircular ends. By making
the ends of the mortise plate and the ends of the opening in the plate semi-
circular, and placing the screw holes in the position described, great facility in
the manufacture of the said mortise plates is secured, and pulleys so made

page_text: can be more readily fitted in the mortise of the window frame or other article
than pulleys having mortise plates of the ordinary kind. My Invention is
applicable to pulleys of the kinds called axle pulleys and box pulleys.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Frederick Ryland in the Great Seal Patent Office on the
3rd February 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
RYLAND, of West Bromwich, in the County of Stafford, Ironfounder, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of August, in the year of our Lord One
thousand eight hundred and sixty-seven, in the thirty-first year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said Frederick
Ryland, Her special licence that I, the said Frederick Ryland, my executors,
administrators, and assigns, or such others as I, the said Frederick Ryland,
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 "IMPROVEMENTS IN PULLEYS FOR SUSPENDING
WINDOW FRAMES, AND FOR OTHER LIKE PURPOSES," upon the condition (amongst
others) that I, the said Frederick Ryland, my executors or administrators,
by an instrument in writing under my, or their, or one of their bands 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 Frederick Ryland, do hereby declare the
nature of the said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following state-
ment, reference being had to the Drawing hereunto annexed, and to the
letters and figures marked thereon (that is to say) :-
My Invention consists of the following improvements in that part of pulleys
for suspending window frames, and for other like purposes, called the mortise
plate. I make the said mortise plate with semicircular ends, and I make in
the centres of the said semicircular ends the holes through which the screws

page_text: are passed to secure the mortise plate in the mortise of the window frame or.
other article; I also make the opening in the mortise plate in which the bowl
or wheel of the pulley works with semicircular ends. By making the ends of,
the mortise plate and the ends of the opening in the plate semicircular, and.
placing the screw holes in the position described, great facility in the manu->
facture of the said mortise plates is secured, and pulleys so made can be more
readily fitted in the mortise of the window frame or other article than pulleys
baving mortise plates of the ordinary kind. My Invention is applicable to
pulleys of the kinds called axle pulleys and box or frame pulleys.
Having explained the nature of my Invention, I will proceed to describe,
with reference to the accompanying Drawing, the manner in which the same
is to be performed.
Figure 1 represents in front elevation and Figure 2 in side elevation an
axle pulley for suspending window frames, and for other like purposes, con-
structed according to my Invention.
a is the mortise plate of the pulley, the ends a², a³, of which are made of a
semicircular figure, the said semicircular ends being struck from the centres
of the holes b, b, through which the screws are passed to secure the said
mortise plate a in the mortise of the window frame or other article ; c is the
bowl or wheel of the pulley working in the opening d in the mortise plate a;
the ends of the said opening d are made of a semicircular figure, as repre-
sented. The axle c³ of the bowl or wheel c turns in the bushes con either
side of the frame e. In other respects the axle pulley represented in Figures 1
and 2 is similar to that ordinarily made.
Figure 3 represents in end elevation, and Figure 4 in side elevation, a box
or frame pulley made according to my Invention; this pulley differs only
from that represented in Figures 1 and 2 in the respects that it has a fixed pin
or axle f upon which the bowl or wheel turns, and that the frame e has a
different shape from that represented in Figures 1 and 2. In the said
Figures 3 and 4 the parts are marked with the same letters as the corres-
ponding parts in Figures 1 and 2.
Pulleys provided with mortise plates of the kind described and represented
in the Drawing are very readily fitted in the mortise of the window frame or
other article in consequence of it being easy to cut the semicircular ends of
the mortise either by means of a brace and bit or wood-cutting machinery.
Having now described the nature of my Invention, and the manner in
which the same is to be performed, I wish it to be understood that I claim as
my Invention the improvements in pulleys for suspending window frames and
for other like purposes, berein-before described and illustrated in the accom-

page_text: panying Drawing, that is to say, making the ends of the mortise plates of the
said pulleys semicircular, and placing the screw holes of the said plates con-
centric with the said semicircular ends. Also making the openings in the said
mortise plates in which the bowls or wheels of the pulleys work with semi-
circular ends, substantially as described. and illustrated.
In witness whereof, I, the said Frederick Ryland, have hereunto set my
hand and seal, this Thirty-first day of January, in the year of our
Lord One thousand eight hundred and sixty-eight.
Witness,
GEORGE SHAW.
FREDERICK RYLAND. (L.S.)
