PROVISIONAL SPECIFICATION.
An, Improved Machine for Drying Tubes.
We ROBERT WOOTTON of 113 Harborne Road Edgbaston Birmingham in the
County of Warwick Gentleman and BENJAMIN HEWITT of Fir Tree. Villa
Waterloo Road Smethwick in the County of Stafford Engineer do hereby
declare the nature of our said invention to be as follows:-
Our invention has for its object an improved machine for drying, tubes audis
for the purpose of receiving solid drawn steel or other tubes during their process
of manufacture or when finished so that all moisture may be at oncel dried up and
deterioration prevented. Our machine is as follows-'
We make, a long tube either square round or other convenient shape, in cross
section which we set upon a suitable foundation or stand in a diagonal position and
with an inlet for dry steam hot air or gas at the lower end and an inlet for any
waste heat at the upper or higher end thereof. At the lower end on the top side
a door is hung so as to open upwards assisted by a balance weight and at the upper
end a door opens downwards also operated by a balance weight and through
which the box is emptied when the tubes are dried. By a modification.of.this
plan a round casing. may be pivoted at its centre on a strong pivot and stand, with
end doors so that the tube can be filled at one end and emptied at the other.
Such a casing may be a large welded tube without a joint thus offering no
impediment to the entry and withdrawal of the tubes but in this case' doors may be
placed as in the previous instance instead of end doors. Stages may be used at
each end to feed and discharge the casing as it is worked upon the pivot or it
may be hung over a recess in the floor. In both cases hot air or gas or dry. steam
is used for the drying of the tubes.

We ROBERT WOOTTON of 113 Harborne Road Edgbaston Birmingham.in the
County of Warwick, Gentleman and BENJAMIN HEWITT of Eir Tree Villa,
Waterloo Road Smethwick in the County of Stafford Engineer, do hereby declare
the nature of our said 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 has for its object an improved machine for drying tubes and is for the
purpose of receiving tubes during their process of manufacture or when finished so
that all moisture may be at once dried up and deterioration prevented. Our
machine is, as follows:-
.
We make a long tube either square round or other convenient shape: in cross
section which, we set upon a suitable foundation or stand in a diagonal-position and

page_text: with an inlet for dry steam hot air or gas at the lower end and an inlet for any
waste heat at the upper or higher end thereof. At the lower end on the top side
a door is hung so as to open upwards assisted by a balance weight and at the
upper end a door opens downwards also operated by a balance weight and through
which the box is emptied when the tubes are dried. By a modification of this
plan a round casing may be pivotted at its centre on a strong pivot and stand
with end doors so that the tube can be filled at one end and emptied at the other.
Such a casing may be a large welded tube without a joint thus offering no
impediment to the entry and withdrawal of the tubes but in this case doors may
be placed as in the previous instance instead of end doors. Stages may be used at
each end to feed and discharge the casing as it is worked upon the pivot or it may
be hung over a recess in the floor. In both cases hot air or gas or dry steam is
used for the drying of the tubes.
In-order that our invention may be clearly understood and more easily carried
into practical effect we have appended hereunto two double sized sheets of
drawings upon which we have illustrated three examples of the mode in which it
may be applied which will serve to enable others to apply the invention to the
various conditions met with in practice and to adapt the invention thereto without
difficulty.
Figure 1 is a side elevation of a drying machine A with its two doors a¹ and a²
open.
Figure 2 is a front elevation of the same machine as shown by Figure 1
exposing to view a number of tubes T placed therein.
Figure 3 is a similar machine fitted up in a different manner and also heated
differently.
Figure 4 is a front elevation of Figure 3 charged with the tubes T.
Figure 5 is the plan of a perforated plate a³ such as is suitable to place at the
bottom end.
Figure 6 is a view of the bottom a without the perforated plate a³.
Figure 7 is a side elevation of a drying machine made from a round welded tube
and mounted upon the trundles R.
Figure 8 is the side elevation of a horizontal machine.
Figure 9 is a cross sectional elevation of Figure 8.
The drying machines shown by Figures 1 to 6 are square in cross section and
are composed of cast iron plates bolted together though they may equally well be
made from wrought iron or steel plates bolted or rivetted together. Figures 1
and 2 show a machine with two doors a' and a² which are operated by the chains C
and weights W over pulleys P for the purpose of feeding the tubes T into and
discharging them from the machine A. The bottom of the machine a* shown by
Figure 6 has inside a perforated plate such for instance as a³ and the hole a³ is
directly over the flue B which is connected with a hot air or equivalent furnace
underneath, and through which air is forced by a fan or its equivalent. This hot
air passes upwards through and outside the tubes T and escapes through the pipe
or chimney S or it may be conveyed to a second drying machine or otherwise
utilized. Both the machine shown by Figures 1 and and 3 and 4 may be
supported by brickwork F or its equivalent to any desired inclination. The
machine shown by Figures 3 and 4 have both the doors a¹ and a² together but it
will be evident that these may be greatly varied to suit the convenience of the
position when the machine is fixed. In this latter case also the heating is
accomplished by a number of gas jets G which are enclosed in the casing B the
waste gases and steam escaping through the pipe S as in the previous instance of
Figures 1,.and 2. Figure 6 also represents the upper end of the casings which the
pipe S meets.
The machine shown by Figure 7 has its body part A made from a welded or
other tube with end doors D D. This machine is hung upon trunnions R which
are secured to the body by the belt and the whole is supported in the plumber
blocks by the pillar F. This machine may be loaded or charged from the

page_text: platform N when it is in the position shown by dotted lines which is mounted upon
pillars M. When the end is lowered into the position as shown on the drawings
the heat is communicated through B as in the previous examples given and escapes
at S in the same manner. The discharge is effected through the bottom door D
when the machine is in the position shown by the dotted lines but any convenient
inclination may be adapted.
Figures 8 and 9 show a machine arranged horizontally with the body A made
from a portion of a tube and the door a' completes the tube. This door a¹ is hung
upon the hinges a and the whole is mounted upon the end trunnions a', a'. The
tube is supported and turns in bearings upon the standards K, K. The inlet
pipe B conveys the hot air or other drying medium and S carries the steam and
waste gases away. By this plan a minimum amount of labor is required in charging
and discharging the machine.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1st. The improved machine for drying tubes substantially as herein set forth and
as shown upon the drawings by Figures 1 to 9 inclusive.
2nd. The drying machine shown by Figures 1 and 2 heated by air forced
through or over a heating furnace and through the machine A which is charged
and emptied substantially as herein set forth and shown by these two figures.
3rd. The drying machine shown by Figures 3 and 4 and heated by gas
substantially as herein set forth and shown.
4th. The drying machine hung upon trunnions R shown by Figure 7 and heated
in any suitable manner substantially as herein set forth.
5th. The drying machine hung upon trunnions a² a' substantially as herein set
forth and as shown by Figures 8 and 9.
