page_text: We, JAMES BINGHAM ALLIOTT, of the firm of Manlove Alliott, Fryer & Co, of
Bloomsgrove Works, in the Town and County of the Town of Nottingham,
Engineer, and GEORGE PENROSE HAUGHTON Draughtsman in the employment of
the said firm, 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:-
Our Invention relates to centrifugal drying machines, which instead of being
firmly bolted down to a solid foundation are suspended from three or more points
and the Invention is especially applicable to that class of machine driven by an
engine forming part of the apparatus and the crank shaft of which is the spindle to
which the revolving cylinder of the drying machine is secured.
It is from time to time necessary to examine the footstep of such machines and
also in the case of such of them as are provided with engines combined with the
machine, the crank pin, eccentric strap and other moving parts which are placed
below the false bottoin of the casing which collects and carries away the water, and
in order to make such examination and to do any work that may be needed it has
been necessary hitherto to make a considerable excavation below the machine
which is often inconvenient or to remove the machine from its position and turn it
on its side.
In order to avoid these inconveniences we suspend the machine by means of
three or more rods which are preferably carried on pillars or columns of suitable
shape and convenient size. One end of each of these rods may be furnished with
a solid head while the other end is provided with a washer and nut or with a nut
only, or both ends may if desired be furnished with washers and nuts or with nuts
only. In any case however we prefer to make either the solid head or the washer
(or when there is a nut unprovided with a washer, then that portion of the nut
which carries the weight) of a rounded or partially spherical form and to form a
suitable recess of corresponding shape in which it may be received. In our
improved arrangement a thread is cut or formed on the whole or a very con-
siderable portion of the length of each of the suspending rods and the rods are so
arranged together with the nut or nuts and washer at one end or at both ends of
each of the rods, that by screwing the nuts or one of the nuts on each rod, the

page_text: whole machine may be raised towards the point from which the rod is suspended
until a sufficient space is left between the lower part of the machine and the
foundation upon which the supporting columns are fixed and thus permit of a
workman getting in below the machine to examine the working parts at the lower
end of the spindle and to perform such work as may be necessary.
And in order that our said Invention and the manner of performing the same
may be properly understood we hereunto append a sheet of explanatory drawings
to be hereinafter referred to and representing our improved arrangements.
On the accompanying sheet of drawings, Figure 1 is a sectional elevation and
Figure 2, is a plan of a centrifugal drying machine arranged according to our
Invention. In the machine represented the revolving cylinder, 1, driven by a
steam engine, 2, is provided with a casing, 3, which encloses or covers the working
parts and the footstep, 4, in which the lower of the revolving shaft is supported,
all being arranged in a well known manner. Instead of the machine being firmly
Becured to a foundation it is by our Invention suspended by three (or more) rods, 5,
from supporting columns, 6, which rest upon a 'foundation plate, 7. These rods, 5,
have a screw thread cut upon each of them throughout their length, and at their
lower ends have each a washer, 8, held on the srewed rod, 5, by a nut, 9. This
washer, 8, is formed of rounded or partly spherical shape, and these washers are
received into a correspondingly rounded recess formed on a suitable part of the
casing, 3, at its lower part. Similar rounded or partly spherical washers are
provided for the upper ends of the rods which likewise fit into rounded recesses
formed for them in the tops of the supporting columns, the rods, 5, being secured
to these columns by nuts, 9.
In this improved arrangement the casing which carriès the cylinder, 1, and all
the moving parts is suspended from the three supporting columns by means of the
three screwed rods, 5, furnished with their nuts, 9, and washers, 8. It is obvious
that by screwing up the nuts, 9, the whole of the machine may be raised as far as
the length of the screwed rods will permit. The arrangements are so contrived as
to permit of the machine being raised to a height sufficient to allow of a man to
get beneath.
In these drawings the machine is represented as furnished with its own
engine (2) but the improved method of suspension may be adopted even when
no engine is combined.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is:-
The arrangement of centrifugal drying machines upon screwed rods whereby
the machines may be raised substantially as and for the purposes hereinbefore
described.
