I, WILLIAM HENRY ROOKE, of Great Hampton Row, Birmingham, in the County
of Warwick, Brass Founder, do hereby declare the nature of this invention to be as
follows:-
This invention relates to what are commonly known as upright pulleys, consisting
essentially of an upright carrying bracket, of somewhat the figure of the letter U,
and with an axle pulley turning within bearing holes through the sides thereof.
The bracket base, is provided with flanged and other attachment parts, through
which screws or their like, pass.
These axle pulleys of the kind described, are usually produced by the process of
casting, which is costly, and is an important item in the cost of manufacturing the
said articles.
By my invention, the brackets for the said upright and other pulleys are produced
from a single blank of sheet metal subsequently operated upon by tools, and shaped
as required.
In carrying out the manufacture, I proceed as follows:-
I take a strip of sheet or plate metal, of a length that will form the carrying
bracket, and its flanged or attachment parts; then double the blank about its
middle, into a figure, resembling the letter U, with the bowed end somewhat
flattened.
The extreme ends of this U-shaped piece of bent up metal, are bent outwardly
at right angles to the sides, and constitute the attachment part or means, by which
the bracket is secured, by screws or the like, passing through holes, pierced there-
through.
The sides of the bracket, are pierced about their middles, with bearing holes,
therethrough or wherein the axle ends of a pulley, disposed between the inside
faces of the bracket sides, work.
Thus the pulley as aforesaid, consists essentially of a carrying bracket, made
from sheet metal, and with the sides directed parallel, and divided from each other,
by a space, equal to the breadth of a pulley, whose axle or ends pass through bearing
holes or piercings in the said sides.

page_text: The bracket may if necessary be made one-sided, with the bracket part shaped
somewhat like that of a pot-hook, with a flange or attachment part.
The flanged ends, may be pierced or cut out with spike like attachments.
The base of the carrying bracket, may be returned or folded upon itself; and if
necessary, the bracket part, or the upright part of the bracket may be made separate
from the base part, and attached thereto, by riveting or otherwise.
Instead of the screws or spikes being independent of the brackets, they may be
laid in, or their heads riveted thereto.
The application of my invention to other pulleys, differs in no essential respect
from its application to an upright pulley as herein described.

Improvements in the Manufacture of Upright and other “Pulleys.
I, WILLIAM HENRY ROOKE of Great Hampton Row, Birmingham in the 'County
of Warwick, Brassfounder do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
This invention relates to what are commonly known, as upright pulleys, consisting
essentially of an upright carrying bracket, or frame of somewhat the figure of the
letter U, and with an axle pulley turning within bearing holes through the sides
thereof.
The bracket base, is provided with flanged and other attachment parts, through
which screws or their like, pass.
These upright pulley frames of the kind described, are usually produced, by the
process of casting, which is costly, and is an important item in the cost of their
manufacture.
mBy my invention, the said upright and other pulley frames are produced from a
single blank of sheet metal, subsequently operated upon by tools, and shaped as
required.

page_text: In carrying out the manufacture, I proceed as follows.
I take a strip of sheet or plate metal, of a length that will form the carrying
bracket, and its flanged or attachment parts; I then double the blank about its
middle, into a figure, resembling an inverted letter U, with the bowed end somewhat
flattened.
The extreme ends of this U-shaped piece of bent up metal, are bent outwardly,
at right angles to the sides, and constitute the attachment part or means, by which
the bracket is secured, by screws or the like, passing through holes, pierced
therethrough.
The sides of the bracket, are pierced about their middles, with bearing holes,
wherethrough or wherein, the axle ends of a pulley, disposed between the inside faces
of the bracket sides, work.
Thus, the pulley frame as aforesaid, consists essentially of a carrying bracket, made
from sheet metal, and with the sides directed parallel, and divided from each other,
by a space, equal to the breadth of a pulley, whose axle or ends, pass through
bearing holes, or piercings, in the said sides.
The bracket may if necessary, be made one-sided, with the bracket part, shaped
somewhat like that of a pot-hook, with a flange or attachment part.
The flanged ends, may be pierced or cut out with spike like attachments.
The base of the carrying bracket, may be returned or folded upon itself; and if
necessary, the bracket part, or the upright part of the bracket, may be made separate
from the base part, and attached thereto, by riveting, or otherwise.
The application of my invention to other pulleys, differs in no essential respect
from its application to an upright pulley, as herein described.
I will now 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, figure 2 in vertical section, and figure 3 in
side elevation, an upright pulley, made according to my invention.
In carrying out the process of manufacture, I proceed as follows.
I take a strip of sheet or plate metal, (figure 4) of sufficient length to form the
carrying bracket, and its flanged attachment parts, I then double the blank about its
middle, into a figure, resembling an inverted letter U, with its ends bent outwardly,
at right angles to the sides, and which bent out ends, constitute the attachment parts,
by which the bracket is secured to an article.
a are the sides of the bracket, a² is the curved top thereof, a³ are the flange attach-
ment parts, and a are holes through the sides of the bracket, wherethrough the
riveted, or expanded ended axis or spindle b, passes, and around which, a loose
pulley c, rotates.
Thus, it will be seen, that the upright, bracket sides, top and flanged attachment
parts, are made in one piece, or from a single blank of sheet, or strip metal.
Figure 5 represents a single pulley frame, provided with spiked attachment parts,
extending downwardly from the ends of the undersides.
By thus making brackets with spiked attachment parts, no loose screws are
required, in securing the pulley to an article.
Figure 6 is an inverted plan of figure 5, while figure 7 represents another form
of upright pulley, in which the frame is made single, and the pulley double. Figure 8
represents a vertical section of figure 7.
a, a, a, constitute the pulley frame, is the axle, and c is a double loose pulley,
working upon the said axle."
Figure 9 represents a double pulley, constructed and made according to my
invention.
a are the sides, a² are the tops thereof, a³ the flange attachment parts, a is a
hanging bearing, coming within a short distance of the base of the bracket frame,
and a are bearing holes, wherethrough an axis, or spindle b, transversely passes,
from one side, to the other of the bracket frame; and around which spindle or axis,
independent and loosely running pulleys, work.

page_text: Figure 10 represents another form of my invention, in which the frame of the
upright pulley, is made in two parts; viz.-the upper frame part, and the base.
a is the upper frame, made separate from the base part a³, which has holes or
piercings, wherethrough the ears, or stem extensions, pass, and are riveted from
the underside, thereby forming an upright pulley frame made in two parts, of which
the base may be of sheet or cast metal.
Figure 11 represents a side elevation, with the base in section, of the said upright
pulley figure 10. Figure 12 is a side elevation of the frame part. Figure 13 is a
plan of the base, and figure 14 is a cross-section of the base, through the counter-
sunk holes.
Although the said pulleys are known in commerce, as upright pulleys, yet the same
may be applied when in use, in any convenient manner.
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 :-
First. Making or forming pulley frames, from a single blank, or length of sheet,
or strip metal, shaped or fashioned into form, substantially as described and set forth
in figures 1, 2, 3, 7, and 8.
Secondly. Forming in one piece with the flanged attachment parts of pulley
frames, (upright or otherwise) attachment spikes, as set forth in figures 5 and 6.
Thirdly. Making double pulley frames, from a single blank or length of sheet or
strip metal, shaped or fashioned into formi, substantially as described and set forth in
figure 9.
Lastly. Making pulley frames, of the kind, herein described, in two parts, and
from sheet or strip metal, or of a sheet metal frame, and cast base, put together in
the manner, substantially as described and set forth, in figures 10, 11, 12, 13 and 14.
