for Drying Sand
Year: 1887

page_text: I, JAMES JOHN PEARSON at present residing with the Reverend J. Pearson of
Shield Field, Newcastle upon Tyne, in the County of Northumberland, Mechanical
Engineer, do hereby declare the nature of this invention to be as follows:-
This Invention relates to apparatus for Drying Sand and these Improvements consist
in the construction arrangement and adaptation of the apparatus in such a manner as
to enable the drying of the sand to be effected by means of high pressure steam.
In the sand containing box or receptacle a coil of steam pipe is erected with an.
outlet communicating with a drain cock. The inlet to the coil is connected to a steam
pipe or boiler and the inlet pipe may or may not be controlled by a cock or valve.
The inlet and outlet pipes are preferably of considerably smaller diameter than the
pipe of which the coil is constructed.. When the drain cock is opened any water
there may be in the coil will be ejected and the coil will be filled with steam the heat
from which will rapidly dry the surrounding sand.
These Improvements are more particularly applicable to Locomotives for drying the
sand employed for giving better adhesion between the wheels and rails when the latter
are wet or greasy. In this application and adaptation of the apparatus the coil may
be placed vertically in the centre of the sand box; the outlet be carried through the
bottom of the box and connected by a small pipe to the drain cock fixed below the
foot plate or in any other convenient position and the inlet be carried through the side
of the box and connected by a small tube with the steam space in the boiler. The
small steam pipe, may pass through a short tube screwed into the boiler shell and
projecting beyond the cleading; a gland or packing nut is fixed upon the outer end
of the short screwed tube through which the steam tube passes into the boiler so that
a steam tight joint may be made. On the part of the screwed tube between the boiler
shell and the cleading there is a sleeve or long collar to give greater steadiness and to
further secure the joint.

page_text: I, JAMES JOHN PEARSON of 7, Commercial Buildings Newcastle-upon-Tyne, in
the County of Northumberland, Mechanical Engineer do hereby declare the nature
of this invention and in what manner the same is to be perforined, to be particularly
described and ascertained in and by the following statement :-
This Invention relates to apparatus for drying sand and these Improvements
consist in the construction arrangement and adaptation of the apparatus in such a
manner as to enable the drying of the sand to be effected by means of high pressure
steam.
In the sand containing box or receptacle a coil of steam pipe is erected with an outlet
communicating with a drain cock. The inlet to the coil is connected to a steam pipe
or boiler and the inlet pipe may or may not be controlled by a cock or valve. The
inlet and outlet pipes are preferably of considerably smaller diameter than the pipe of
which the coil is constructed. When the drain cock is opened any water there may be
in the coil will be ejected, and the coil will be filled with steam the heat from which
will rapidly dry the surrounding sand.
These improvements are more particularly applicable to Locomotives for drying the
sand employed for giving better adhesion between the wheels and rails when the latter
are wet or greasy.
In the accompanying sheet of drawings reference to which is hereinafter made this
invention is shewn applied to only one sand box but it is evident that two or more
sand boxes may be heated from one pipe thus necessitating only one perforation of the
boiler shell.
Fig. 1 is an elevation of part of a locomotive shewing the improved drying apparatus
attached thereto, and Fig. 2 is a section through the sand box and boiler. In both
these views similar letters are used to indicate similar parts.
L is the sand box containing a coil of steam pipe D one end of which is connected
by means of a small pipe A with the steam space of the boiler. The other end of the
coil is furnished with a pipe C leading to the drain cock F. If preferred however the
pipe C may be carried on to the feed tank or into the engine exhaust. Secured to the
shell of the boiler and projecting through the cleading is a short tube K provided with
a gland or stuffing box and through which the steam pipe A passes. G is the pipe
for conducting the dried sand to the rails and is provided with a valve E operated by
a rod in the usual manner. The tube K is furnished between the cleading and the
boiler shell with a long collar or sleeve to give greater steadiness and to further secure
the joint.
The passage of steam through the coil as well as the egress of sand from the sand
box may be controlled from the foot plate.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
(1) An apparatus for drying sand, constructed arranged and operated substantially
as hereinbefore described.
(2) In an apparatus for drying sand the combination with a sand box or receptacle
of a coil or equivalent length of steam pipe connected with a source of steam supply;
substantially as herein before described.
