Year: 1861

page_text: LETTERS PATENT to Joseph Terry, of Birmingham, in the County of
Warwick, Brass Founder, for the Invention of "AN IMPROVEMENT OR
IMPROVEMENTS IN THE MANUFACTURE OF WINDOW SASH PULLEYS, SIDE
PULLEYS, SCREW PULLEYS, AND UPRIGHT PULLEYS."
Sealed the 5th September 1861, and dated the 3rd July 1861..
PROVISIONAL SPECIFICATION left by the said Joseph Terry at the
:...
Office of the Commissioners of Patents, with his Petition, on the 3rd
July 1861.
... I, JOSEPH TERRY, of Birmingham, in the County of Warwick, Brass
Founder, do hereby declare the nature of the said Invention for "AN IMPROVE-
MENT OR IMPROVEMENTS IN THE MANUFACTURE OF WINDOW SASH PULLEYS, SIDE
PULLEYS, SCREW PULLEYS, AND UPRIGHT PULLEYS," to be as follows:-
My. Invention consists in manufacturing window sash pulleys, side pulleys,
screw pulleys, and upright pulleys of glass, china, earthenware, or other
vitreous or semi-vitreous material, instead of making them of metal as ordinarily
practised. I make the said pulleys of the shapes of which they are ordi-
narily made when made of metal, each pulley having a hole in the centre. In
the said hole a metal axis is fixed for the pulley to work upon, or the axis
may work loose in the said hole, or a bush or collar of inetal may be fixed in
the said hole, in which bush or collar the axis of the pulleys works.. I make
the said pulleys by the processes ordinarily practised in manufacturing other
articles of glass, china, earthenware, and other vitreous and semi-vitreous

filed by the said Joseph Terry in the Great Seal Patent Office on
the 9th September 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
TERRY, of Birmingham, in the County of Warwick, Brass Founder, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of July, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fifth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Joseph Terry, Her special licence that I, the said Joseph
Terry, my executors, administrators, and assigns, or such others as I,
the said Joseph Terry, 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
"AN IMPROVEMENT OR IMPROVEMENTS IN THE MANUFACTURE OF WINDOW SASH
PULLEYS, SIDE PULLEYS, SCREW PULLEYS, AND UPRIGHT PULLEYS," upon the
condition (amongst others) that I, the said Joseph Terry, my executors
. or administrators, by an instrument in writing under my, or their, or. one
of their hands 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 Joseph Terry, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:
My Invention consists in manufacturing the pulleys or rollers of window
sash pulleys, side pulleys, screw pulleys, and upright pulleys of glass, china,
earthenware, or other vitreous or semi-vitreous material, instead of making
them of metal as ordinarily practised.

page_text: said Figures 1,
Figures 4, 5,
Figure 1 of the accompanying Drawing represents in side, elevation a
window sash pulley made according to my Invention; Figure 2 is a front
elevation of the same; and Figure 3 is a section, of the same. The pulley.or
roller made of glass, china, or earthenware, is marked a in the
2, and 3, and the metal frame of the said pulley is marked b.
and 6, represent in front elevation, side elevation, and section respectively, a
side pulley made according to my Invention. The glass, china, or earthenware
pulley or roller is marked c, and the metal frame in which the said pulley c
works, and by which it is fixed in its place is marked d in each of the said
Figures 4, 5, and 6; Figure 7 represents in side elevation and Figure 8 in
front elevation, a screw pulley made according to my Invention. The glass,
china, or earthenware pulley or roller is marked e, and the frame in which it
works is marked g. The frame g.is fixed on the screw.f. Figure 9 repre-
sents in front elevation, and Figure 10 in side elevation an upright pulley
made according to my Invention. In the said Figures 9. and 10, the glass,
china, or earthenware pulley or roller is marked h, and the metal frame in
which it works is marked i; Figures 11 and 12 represent in section and side
elevation respectively the modification of a side pulley used for French rod
ends made according to my Invention. The frame k in which the glass,
china, or earthenware pulleys or rollers and m work is made on the end of
-the tube n, to which latter the rod is fixed as is well understood. The shapes
of the glass, china, or earthenware pulleys or rollers, and the metal frames or
bodies in which they work herein-before described and represented in the
Drawing, are the same as those of ordinary pulleys. The frames or bodies of
the pulleys may be made to carry two, three, or more glass, china, or earthen-
ware pulleys or rollers, and the said glass, china, or earthenware pulleys or
rollers, may be of any size or shape required for the purpose to which they
are to be applied.
I do not limit myself to the particular construction of the frames or bodies
of the different kinds of pulleys herein-before described and illustrated in the
Drawing, as my Invention may be applied to pulleys of the kinds herein-
before enumerated, the frames or bodies of which are differently constructed,
and have a different shape from those represented in the Drawing.
I prefer to mount the pulleys or rollers made according to my Invention in
either of the ways illustrated with reference to the sections, Figures 13, 14,
and 15 of the Drawing, that is to say, I make in the centre or axis of the
glass, china, or earthenware pulley a hole, in which I fix a metal rod or
axis o as represented in Figure 13, the said rod or axis o turning freely in the
frame p.. and bushes or nuts q fixed on either side of the said frame p. Or

page_text: .
the metal rod or axis may work loose in the hole in the pulley as represented in
Figure 14, the said axis being marked r. In this case the ends of the metal
axis rare fixed in the nuts or bushes s, and the pulley rotates on the said axes;
or, when the pulley rotates on a fixed metal axis, as in Figure 14, I some-
times insert and fix in the sides of the pulley collars or bushes t as represented
in Figure 15, which bushes or collars & bear against the metal axis u as the
pulley rotates; or, instead of the bushes or collars t, a metal tube may be
inserted and fixed in the hole in the pulley, and the said metal tube work
against the fixed. axis of the pulley.
Although for convenience of description I have only described the pulleys
, or rollers of the different kinds of pulleys represented in the Drawing as made
of glass, china, or earthenware, yet the said pulleys or rollers may be made of
other vitreous or semi-vitreous material in place of the said glass, china, or
earthenware..
I manufacture the said pulleys or rollers made of glass, china, earthen-
.ware, or other vitreous or semi-vitreous material, by the processes ordinarily
practised in manufacturing. other articles of glass, china, earthenware, and
other vitreous or semi-vitreous material, which said processes are well known
.and commonly practised, and constitute no part of my Invention, and I there-
fore do not consider it necessary to describe the said processes.
Having now described the nature of my Invention, and the manner of carry-
ing the same into effect, I wish it to be understood. that I claim as my
Invention the improvement or improvements in the manufacture of the
pulleys or rollers of window sash pulleys, side pulleys, screw pulleys, and
upright pulleys herein-before described and illustrated in the accompanying
Drawing, that is to say, making the said pulleys or rollers of glass, china,
earthenware, or other vitreous or semi-vitreous material, instead of making
them of metal as ordinarily practised.
:
In witness whereof, I, the said Joseph Terry, have hereunto set my
hand and seal, this Seventh day of September, in the year of our
Lord One thousand eight hundred and sixty-one.
