Year: 1836

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
YOUNG, of Wolverhampton, in the County of Stafford, Patent Locksmith,
send greeting.
WHEREAS His present most Excellent Majesty King William the
Fourth, by His Royal Letters Patent under the Great Seal of Great Britain,
bearing date at Westminster, the Twenty-first day of June, in the sixth
year of His reign, and in the year of our Lord One thousand eight hundred
and thirty-six, did, for Himself, His heirs and successors, give and grant
unto me, the said John Young, His especial license, full power, sole privilege
and authority, that I, the said John Young, my executors, administrators, and
assigns, or such others as I, the said John Young, my executors, administrators,
or assigns, should at any time agree with, and no others, from time to time
and at all times during the term of years therein mentioned, should and
lawfully might make, use, exercise, and vend, within England, Wales, and the
Town of Berwick-upon-Tweed, my Invention of "CERTAIN IMPROVEMENTS IN
MANUFACTURING BOXES AND PULLIES FOR WINDOW SASHES AND OTHER PURPOSES;" in
which said Letters Patent is contained a proviso obliging me, the said John
Young, by an instrument in writing under my hand and seal, particularly
to describe and ascertain the nature of my said Invention, and in what
manner the same is to be performed, and to cause the same to be inrolled

page_text: in His Majesty's High Court of Chancery within six calendar months next
and immediately after the dato of the said in part recited Letters Patent,
as in and by the same, reference being thereunto had, will more fully and at
large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said.
John Young, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are particularly described
and ascertained in and by the following description thereof, reference being
had to the Drawing hereunto annexed, and to the letters and figures marked
thereon (that is to say) :-

My Invention of Certain Improvements in Manufacturing Boxes and Pullies
for Window Sashes and other Purposes apply to that description of pullies
commonly called "box pullies," such as are generally used for sustaining the
cords or lines of the counter balance weights of window sashes. And my improve-
ments apply more particularly to that kind or description of "box pullies" which
have the axle of the pulley or wheel securely fixed therein, and turning in holes
or bearings formed in the sides of the box or case, and are generally deno-
minated in the trade axle pullies," to distinguish them from another kind
of "box pulley," in which the pulley or wheel revolves upon a pin or axle
passed through it, and the sides of the box or case, and secured therein by
riveting the ends of the pin on to the outside of the box, which, in this
instance, is cast in one piece, and after the holes have been drilled therein the
pulley or wheel is placed in its proper situation, and the pin or axle passed
through them, which secures the pulley or wheel in the box, whereas in the
former description of the "axle box pullies" as commonly made, the case is
cast in two or three pieces, the sides thereof, after having the holes drilled
through them, being rivetted or otherwise secured to the other or front part of
the box or case, the fastenings of the sides thereto holding or securing the
pulley or wheel between them.
And my Invention consists in casting the said box or case of the last-
mentioned description of "axle pullies" around the pulley wheel after it
has been properly prepared for this purpose, the pulley wheel or roller
being contained within the "core," which occupies the space forming the
interior of the said box or case when it is placed within the "sand mould."
The fluid metal being poured into the "mould" flows around the ". core,"
and into the parts or spaces left between it and the sides of the "mould," or
impression of the "pattern" of the box, by which means the box or case
is cast around the pulley or wheel, which is thereby properly held or secured
in its required situation without requiring further fitting up. The several

manufacture of "axle pullies."

Fig. 1 is a front view, Fig. 2 a side view, and Fig. 3 a back view of one
of
my improved pullies complete. Fig. 4 is a representation of the pulley
wheel or roller detached. a is the box or case. b, the pulley or wheel.
c; the axle thereof. Figures 5 and 6 are representations of the interior of the
two halves or sides of the "core box." Figures 7, 8, and 9 are side and. end
representations of the "core" complete, with the pulley or wheel contained
therein. Figures 10, 11, and 12 are front, side, and back representations of
the moulder's pattern for the box or case; and Figures 13 and 14 are longitu-
dinal and transverse sections of the sand mould, shewing the "core" situated"
therein. After the pulley wheels have been properly prepared, as shewn in
Figure 4, that is, with the ends of the axles turned in a lathe they are severally
placed within the "core box," the ends of the axles fitting into the counter-
sunk holes d, d, the "core box" is then filled with sand, which is rammed
therein around the pulley wheel so as to form a compact "core," the
impression of the pattern of the box or case is then properly formed in the
sand by the moulder when the "core," with the pulley wheel, is placed therein,
the ends of the axle projecting from the "core" into the space between the
"core" and "mould," as shewn in Figure 14; the fluid metal is then poured
into the mould, which flows into the spaces between the sides thereof and
the "core," and around the ends of the axle of the pulley, which project_from
the "core," and as soon as the metal is cold the operation is complete, the
core sand being removed from out of the interior of the now-formed box or
case in the usual manner. If it should be thought desirable, smooth turned
collars, bushes, or bearings of metal e, as shewn at Figure 15, may be placed
on each side of the core, around the ends of the axis of the pulley wheel,
as seen in Figure 16, previous to its being put into the sand mould,
whereby the fluid metal will be made to flow around the said collar instead of
coming in direct contact with the axle.
the "box pulley," shewn in Fig. 17, and the axle will thereby have a better
bearing than in the former instance, care being taken to use such a metal or
mixture of metals as will not be melted by the fluid metal of which the cast is
formed when it is poured into the mould.
This mode of operation will produce
In witness whereof, I, the said John Young, have hereunto set my
hand and seal, this Third day of December, in the year of our Lord
One thousand eight hundred and thirty-six.
