Sealed the 22nd December 1870, and dated the 25th June 1870.
PROVISIONAL SPECIFICATION left by the said Esau Lambert at the
Office of the Commissioners of Patents, with his Petition, on the
25th June 1870.
I, ESAU LAMBERT, of Eagle, in the County of Lincoln, Gentleman,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE CONSTRUCTION AND ARRANGEMENT OF STAGES MADE OF IRON OR OTHER SIMILAR
MATERIAL APPLICABLE TO WINDMILLS OR OTHER BUILDINGS OR ERECTIONS OR
STRUCTURES," to be as follows:-
:-
These improvements consist of separate parts, and they are constructed
and arranged as follows:-One or more series of iron rods or bands,

page_text: each series consisting of as many rods as will when connected encompass
the tower or other building or erection or structure on which the stage
is to be fixed, whether temporarily or permanently employed. The rods
of each series have a screw thread tapped on one of their ends, the other
end being formed with an eye to receive the screwed end of the next
adjoining rod, which screwed end when passed through the eye has a
nut screwed upon it; these nuts when tightened up will cause each
series of rods to tightly embrace the tower or other building which they
encompass. There are numerous horizontal bearers or levers, which
bearers or levers have each two or more eyes, when two eyes only are
used, one at each end, and lying at right angles to each other. There
aro also a number of other bearers which lie at an angle when in use.
These bearers also have an eye at each end; there are also a number of
connecting rods, each of which rods have an eye at each end. These
rods lie upon the straight or inclined walls of the tower or other
building. Through these eyes at the upper ends of the connecting rods
the series of rods first mentioned are threaded, being also threaded
through the horizontal eyes of the bearers. The rods are then con-
nected by their secured ends and nuts, and the lower series of rods are
threaded through the eyes at the lower ends of the connecting rods and
also through the eyes at the lower ends of the bearers lying at an angle,
such lower series of rods are then connected in the same manner as the
upper series, and the outer ends of the horizontal levers or bearers and
the upper ends of the inclined bearers are brought nearly together, a
band of iron or other convenient metal being interposed between them.
This band is connected in the same way as either of the series of rods
above referred to, and has also a number of holes punched or otherwise
formed in it to receive the screwed pins formed on the lower ends of the
upright bars, which screwed pins are passed through the eyes of the
horizontal and inclined bearers and the band, and they are secured
therein by a nut on the under side thereof. The upright bars form posts
for a railing, holes being punched or otherwise formed at their upper
ends and intermediately to receive a round or otherwise shaped rod or
bar forming the railing; such arrangement of parts when either per-
menently or temporarily fixed will form a strong and secure staging
around the mill, tower, or other building at or to which the staging is
employed, such staging when used temporarily may be raised as the
building is erected, or in course of reparation, by suspending such stage

upper ends of poles; and when the stage is fixed the series of rods may
be threaded through the eyes of bolts passed through the walls of the
building and secured by a nut on the inside.
by two or other number of chains or ropes with blocks secured to the
upper ends of poles; and when the stage is fixed the series of rods may
be threaded through the eyes of bolts passed through the walls of the
building and secured by a nut on the inside.
In erecting my stage in buildings completed or in course of com-
pletion, I do not disturb a single brick or stone.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Esau Lambert in the Great Seal Patent Office on
the 23rd December 1870.

page_text: say):
My Invention has for its object improvements in the construction and
arrangement of stages made of iron or other suitable material applicable
to windmills or other buildings or erections or structures. One or more
series or sets of iron rods or bands is or are used, each set or series con-
sisting of as many rods as will when connected together encompass a
tower, mill, or other building, erection, or structure on which the stage is
to be fixed whether temporarily or permanently employed. The rods of
cach series or set have a screw thread tapped on one of their ends, the
other end being formed with an eye to receive the screwed end of the
next adjoining rod which screwed end when passed through the eye has
a nuit screwed upon it. These nuts when tightened up will cause each
series of rods to embrace tightly the tower or other building which they
encompass. There are numerous horizontal bearers or levers which have
each two or more eyes, when two eyes only are used, one at each end, and
lying at right angles to each other. There are also a number of other
bearers which lie at an angle when in use. Each of these bearers also has
an eye at each end. There are also a number of connecting rods, each
of which rods has an eye at each end. These rods lie upon the straight
or inclined walls of the tower or other building or structure. Through
these eyes at the upper ends of the connecting rods the series or sets of
rods first mentioned are threaded being also threaded through the
horizontal eyes of the bearers. The rods are then connected as above
stated by their screwed ends and nuts and the lower series or sets of
rods are threaded through the eyes at the lower ends of the connecting
rods and also through the eyes at the lower ends of the bearers lying at
an angle; such lower series or sets of rods are then connected in the
same manner as the upper series or sets and the outer ends of the
horizontal levers or bearers and the upper ends of the inclined bearers
are brought nearly together, a band of iron or other convenient metal
being interposed between them. This band is connected in the same
way as either of the series or sets of rods above referred to, and has also.

page_text: a number of holes punched or otherwise formed in it to receive the
screwed pins formed on the lower end of the upright bars, which screwed
pins are passed through the eyes of the horizontal and inclined bearers
and the band, and they are screwed therein by a nut on the underside
thereof. The upright bars form posts for a railing, holes being
punched or otherwise formed at their upper ends and intermediately to
receive a round or otherwise shaped rod or bar forming the railing; such
arrangement of parts when either temporarily or permanently fixed will
form a strong and secure staging around the tower, mill, or other
building or structure at or to which the staging is employed. Such
staging when used temporarily may be raised as the building is being
erected, or in course of reparation, by suspending such stage by two or
other number of chains or ropes with blocks secured to the upper ends
of poles sufficiently high for the purpose, and when the stage is per-
manently fixed the sets or series of rods may be threaded through the
eyes of bolts passed through the walls of the building or structure and
the inside tharraf
Figure 1 represents in plan one of my improved stages as permanently
fixed to the tower of a windmill or other circular building. In this
view portions only of the floor boarding are shown so as to enable some
of the connections and the relative positions of separate parts to be seen.
Figure 2 is a side view of the above.
Figure 3 shews in plan one of my improved stages which may be
temporarily or permanently fixed to a square or otherwise shaped mill
or other building or structure with four or other number of right-angled
or otherwise shaped corners. In this view the floor boards are not
shown. Figure 4 is a side view of the same.

page_text: Figure 5 is an enlarged view of a portion of a circular building
shewing in plan the method of connecting the ends of the series of rods
and bars which encompass the building and assist in forming one of my
improved stages. Figure 6 is a side view of the same taken at a right
angle to the wall of a circular building, and shewing in section the floor
boards, rods, and an angular bar hereafter referred to. Figure 10 is a
similar view of a square or otherwise shaped building encompassed by
angular bars instead of rods. Figures 7, 8, 9, 11, 12, and 13 are separate
views of parts also hereafter referred to.
These improved stages consist of separate parts combined, and are
constructed and arranged as follows:-In one modification there are two
sets or series of iron rods A and B, seen at Figures 1, 2, 5, and 6, each set
or series consisting of as many rods as will, when connected, encompass
the building on which the stage is to be fixed, whether temporarily or
permanently employed. The rods of each set or series have a screw
thread tapped on one of their ends, the other end being formed with an
eye to receive the screwed end of the next adjoining rod, which screwed
end when passed through the eye has a nut screwed upon it; such
connections are shewn at Figures 7 and 8. These nuts when tightened
up will cause each set or series of rods tightly to embrace the building
which they encompass. There are a number of horizontal bearers E,
which have each two eyes, one eye at each end, and lying at right angles
to each other. There are also a number of other bearers D, which have
an eye at each end and lie at an angle beneath the horizontal bearers.
To each length of the rods A and B there are two or more connecting
rods K, each of which rods K has an eye at each end. These rods
when in place serve to connect the series of rods A and B and keep
them at the required distance apart and parallel to each other. Through
the eyes at the upper ends of the connecting rods the rods of the series
or set A are threaded, being also threaded through the horizontal eyes
of the bearers E, and if the stage is to be only temporarily fixed the
rods are then connected by their screwed ends and nuts. But if the
stage is required to be permanently fixed the rods A before being
connected are also passed through the eyes of holding bolts H, which
pass through the walls of the building, and have their other ends
tapped with a screw thread and are provided with a nut and a washer
or plate by which they are secured in the walls. The rods of the
series or set B are threaded through the eyes at the lower ends of the

page_text: connecting rods and also through the eyes at the lower ends of the
bearers D, and are then connected if the stage is to be temporarily
employed, but if permanently, then the rods B previously to being
connected are passed through the eyes of holding bolts H', which pass
through the walls of the building and are secured therein in the same
way as the bolts H. The outer ends of the bearers E and the upper
ends of the bearers D are brought nearly together, a band of iron or
one of the flanges of an angle iron C being interposed between them.
If a band of iron is employed the several lengths are then connected in
the same way as the sets or series of rods A and B, but if an angle iron
is employed then the connection is made by cutting away at each end
of the bar a portion of one of the flanges and bending the corresponding
portion of the other flange at a right angle to the length of the bar;
such bent portions then have a hole drilled or otherwise formed in them,
through which holes a screw bolt is passed provided with a nut, by
which the ends of the bar are brought together. Such connection is
shewn at Figure 9. The bar has also a number of holes punched or
otherwise formed in it to receive the screwed pins formed on the lower
end of the upright bars F, which screwed pins are also passed through
the eyes of the horizontal and inclined bearers and are secured therein
by nuts on the under side thereof. The upright bars form posts for a
railing, holes being punched or otherwise formed at their upper ends
and intermediately to receive a round or otherwise shaped rod or bar,
which rods or bars form the railing I, I, I. If the railing is formed of
round rods the ends of them may be tapped with a screw thread and be
passed through holes in the uprights, and each end be secured with a
nut as shewn at the upper end of the upright at Figure 6; and if the
railing is formed of flat bars the ends of the bars may be turned at a
right angle, have a holo punched through the turned parts, and then
be brought together by a screw pin and a nut; or the ends of the
bars, when they have been passed through the slits in the uprights, may
be cut off short and be bent down on to the uprights; both these
methods being shewn at Figures 6. Upon the bearers E floor boarding
G, shewn at Figures 1, 2, and 6, is laid; if for temporary use only such
boarding may be laid loose and removed from one part of the staging to
another, or the boards may be cut to the shape of the outer walls of
the building and be nailed to each other, or holes may be made where
required in the bearers E, and the bearers be secured to the boarding
may

page_text: by screws or nails, if for permanent use. When staging, as above
described, is employed in square or otherwise shaped cornered buildings
I then employ the method shewn at Figure 11 for connecting the rods
at the corners.
In a second modification applicable to buildings in course of erection,
or to buildings already erected, I employ instead of the sets or series of
rods A and B angle irons A¹ and B', and instead of the rods and
bearers D, E, and K, I employ rods and bearers D', E' and K', which
have their ends bent at an angle of their length, such bent ends being
pierced with a hole for the passage of the screw pins, and I connect
them as above described in my first modification; such arrangement is
shewn at Figure 10. In this arrangement of parts continuous lengths
of angle irons A', B' and C are connected as before described as shewn
at Figure 9. The corner connections of the angle irons A and B are
effected by riveting a screwed pin to one of the flanges at one end of one
bar, the screwed pin projecting beyond the end is passed through a
hole in one of the flanges near the end of the other bar, both bars
being brought together by a nut as shewn in plan and side view at
Figure 12. The corner joint or connection of the outer angle iron C, I
effect by cutting away a portion of the length of the top flange of one
end of one bar, and bending the corresponding length of the vertical
flange at an angle, such bent part and one end of the vertical flange
of the other bar being cach pierced with a hole to receive a screw
bolt they are brought together by a nut, the top flange of one bar
lying upon the vertical flange of the other bar as shewn in plan at
Figure 13. Such arrangement of parts when either temporarily or per-
manently fixed will form a strong and secure staging around the
building, at or to which the staging is employed, such staging when
used temporarily may be raised as the building is being erected, or in
course of reparation, by suspending such stage by the employment of
two or other number of chains or ropes with blocks secured to the
upper ends of poles sufficiently high for the purpose. In erecting such
stages on buildings already completed, or in course of completion, there
is no necessity to disturb a single brick or stone of which they are
composed.
dennuibed the nature of the said Invention and in what

page_text: arrangement and combination of parts, substantially as hercin-before
described for the purpose set forth.
In witness whereof, I, the said Esau Lambert, have hereunto set
my hand and seal, this Twenty-second day of December, in the
year of our Lord One thousand eight hundred and seventy.
