PROVISIONAL SPECIFICATION.
An Appliance for Use in Determining the Temperature in the
Interior of Ricks, Bales, or Grain or the like in Bulk, applicable
also for the Supply of Water in Case of Fire.
ALFRED LAWRENCE 3 High Street Chippenham Wilts. Sergeant Major
PERCY BAYLIS The Foundry Chippenham Wilts. Civil Engineer, do hereby
declare the nature of this invention to be as follows:-
It consists of a metal rod having a worm on one end with a thermometer
contained in a shield attached and on the other end a handle for screwing the same
into a rick for the purpose of ascertaining the temperature of the interior and
thus indicating any danger of spontaneous combustion.
It may also be made in the form of a perforated tube with a similar worm on
one end and formed to receive a handle and union on the other end for fixing the
delivery of a pump and injecting water in the event of the interior becoming
ignited.
The thermometer can be fixed to a suitable rod and passed down the tube when
the temperature of the interior can be ascertained from time to time. The
instrument may also be used for the same purpose in the case of bales of cotton or
hemp, grain in bulk or any other material liable to spontaneous combustion.
Dated this 17th day of October 1893.

COMPLETE SPECIFICATION.
An Appliance for Use in Determining the Temperature in the
Interior of Ricks, Bales, or Grain or the like in Bulk, applicable
also for the Supply of Water in Case of Fire.
ALFRED LAWRENCE 3 High Street Chippenham Wilts. Sergeant Major of
Yeomanry and PERCY BAYLIS New Road Chippenham Wilts. 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:-
The apparatus consists of a tube A of iron or any other suitable material
provided at one end with a coarse threaded screw or worm B of such a size and
form that it can be screwed into the material to be tested by means of a handle C
attached or applied to the other end this end of the tube is also provided with a
suitable means of attachment D to a hose or pipe to enable a supply of water to
be introduced into it. The tube A is to be perforated for a portion or the whole
of its length by holes E of the required size to ensure the passage of water into
the material or for ventilation or to facilitate the passage of heat from the material
to the interior of the tube A.
To enable the temperature of the material to be ascertained we pass a
thermometer preferably a maximum attached to a rod of sufficient length down
the said tube the said thermometer having a conspicuous mark shewing when a
dangerous temperature has been reached.
The perforated tube and the rod on the thermometer may be made in one or
several lengths easily detachable to adapt them to the different purposes for which

page_text: they may be required. The worm may also be formed on the outside of the tube
for the whole or part of its length.
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
The several arrangements and combinations of parts herein described when
employed in manner stated as set forth for the purpose of ventilation and
ascertaining the interior temperature of ricks, bales, silo pits or grain or the like
in bulk and the means or power of introducing water in the case of fire.
Dated this Seventeenth day of July 1894.
