I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street,
Manchester, both in the County of Lanra-ter, and 323, High Holborn, in the
County of Middle-ex, Civil Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in building towers or the like; and the
object of the improvements is to provide means whereby the tower may be built at
great height without employing a proportionately heavy or massive framework to
support the shaft. This is accomplished by constructing the tower in the manner
hereinafter described, and by staying it with a system of network of steel cables
disposed at certain points on the tower, all as will be fully set forth.
In place of the great body of framework, which would ordinarily be necessary in
the tower, a comparatively slender tower or shaft is built, and a system of steel
cables connected with it is employed, which form a network of stays for the shaft
o support it at various points from the bottom to the top.

A communication by THEOPHILUS REICHARD, of the City of Brooklyn, County
of Kings, United States of America, Gentleman.
I, WILLIAM PHILLIPS THOMPSON F.C.S. M.I.M.E. of the Agency for
Foreign Patent Solicitors 6, Lord Street Liverpool and 6, Bank Street,
Manchester both in the County of Lancaster and 323 High Holborn in the
County of Middle-ex, Civil Engineer 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 improvements in building towers or the like; and the
object of the improvements is to provide a means whereby the tower or such like
structure may be built to a great height without employing a proportionately heavy
and massive framework to support it and this is accomplished by building the
structure in the manner hereinafter de-cribed and by staying it with a system or
net-work of steel cables disposed at certain points on it, all as will be fully
set forth.
In the drawings which clearly illustrate the novel features of these improve-
ments,
Figure is a perspective view of a tower embodying such improvements and
shown connected with a building; and

Figure 1.

preferably made of glass.
c is the tower-shaft. This shaft extends down through the building and is
provided with an entrance d, leading out from the building. The shaft e is hollow,
so that ascent may be had through the interior to the top of the same. Above the
dome of the building a, through which it passes, it rises in three sections e, f and !
the lower one being of uniform diameter, as is also the second one; but the third is
made tapering to the top and terminates in a dome-shaped extremity .
his a square platform which intersects the two lower sections of the tower, and
which is built and arranged for the purpose of a garden. Above the platform is
built a dome-shaped structure i of glass, which is adapted for a conservatory. The
shaft is continuous through the structure . A similar platform j and dome-shaped
building are built on the top of the second section. The tapering section
likewise surmounted by a platform and dome-shaped building m, and both of
these platforms are designed to be converted into gardens.

In place of the great body and framework which would ordinarily be necessary
in a tower, a comparatively slender tower or shaft is built and a system of steel
cables employed connected with it, which form a net-work of stays for the shaft to
support it at various points from the bottom to the top.
From the top of the shaft c are suspended cables n'nn and n, each one of which
is attached to a corner of the platform j, and is extended down and similarly
attached to a corner of the lower platform 4, and has its end connected to the
building a and anchored in the ground at the point o. Four other cables PP. P
and p are attached to the shaft just beneath the second platform j, which cables
are made to pass through the lower platform h, and are connected and anchored at
their ends with the four previously mentioned ones at the points o.
Below the
lower platform are attached four more cables qqqand, which four are extended
down and united with the other eight cables at the points o, before mentioned.
From the points ss and s on the shaft and about midway between the platforms
are attached a series of cables ttt, etcetera, which are made to diverge or to spread
outward from their single point of connection, and are united to the other cables n
P
and 9, that are suspended vertically from the shaft, so that the cables of each
series are united and stayed and also connected with the shaft at the points s s
and 3.

Whilst the invention has been described in its connection with towers, such has
been done by way of example only, and for convenience of description, it is easily
seen therefrom how the invention can be as well carried out in the construction of
chimneys or the like.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is :-
1. The improvements in the construction of towers, chimneys, or the like, con-
sisting in constructing them of a hollow shaft composed of three sections with
intervening projecting platforms, with dome-shaped structures in the case of towers,
above said platforms, and a series of cables connecting the tower chimney or the
like and platforms, as set forth.
2. The improvements in the construction of towers chimneys or the like, con-
sisting in forming them of three sections with intervening platforms, vertical cables
connecting the shaft and platforms, and cables attached at intermediate points
between said platforms and connected to the vertical cables, as set forth.
