Improvements in Apparatus for the Manufacture of Explosives.
I, HENRY FRANCIS TALBOT of 7 Cherry Street, Birmingham, in the County of
Warwick, Patent Agent, do hereby declare the nature of this invention to be as
follows:-
This invention applies to a vacuum apparatus for drying and letting out the gas
from powder and other explosives the use of which will avoid the breaking of the
main apparatus by explosion and will reduce the risks run by the attendants. This
is attained by use of parts of the apparatus being constructed so as to be easily
changed or replaced, and made of material of less solidity than the main walls of
the apparatus so that in case of explosion these weaker parts only will give way
whereas the main portion of the drying apparatus itself will remain unhurt.
The apparatus which may be of any convenient shape can be closed airtight by
one or more doors and a vacuum created in the apparatus by the application of an
air pump or similarly acting appliance to a valve or vent arranged for that purpose
in the apparatus.
To produce the necessary warmth, warmth exchanging bodies of any suitable shape
are used between which, or upon which, the explosives are put in.
Any desired portion or portions of the walls of the apparatus may be made
detachable so as to be easily replaced when broken and such portions being made
of material of less strength and solidity than the remaining portions of the walls of
the apparatus, these weaker portions in case of explosion will be the only parts
destroyed leaving the main portion of the apparatus unhurt.

COMPLETE SPECIFICATION.
Improvements in Apparatus for the Manufacture of Explosives.
I HENRY FRANCIS TALBOT of 7 Cherry Street Birmingham in the County of
Warwick Patent Agent, 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 a vacuum apparatus for drying gun-powder and other
explosives, or for removing gases therefrom.
The object of the invention is to prevent a complete destruction of the apparatus
in the case of an explosion and thus to diminish the danger of serious accidents. To
this end, I construct the walls of the apparatus with readily exchangeable sections of
less strength than the remainder of the said walls, so that in the case of an
explosion only these relatively weak sections will be destroyed, while the body of the
apparatus remain uninjured.

page_text: Reference is to be had to the accompanying drawings, in which similar letters of
reference indicate corresponding parts in the figures.
Figure 1 is a sectional elevation of my improved apparatus ;
Figure 2 is a sectional plan thereof;
Figure 3 is a front view thereof;
Figure 4 shows an upper view of a form of modification.
In carrying out my invention, I construct the apparatus D of several rigidly
connected parts and place it upon any suitable base or support, s. A tubular stem B
is secured to the apparatus and is adapted for connection with an air pump or
equivalent exhausting device. In order to produce within the apparatus the heat
required for thorough drying, I provide horizontal superposed heating bodies C.
The explosives to be dried are placed upon or between these heating bodies. Pipes or
coils or any other approved type of heating bodies may be used.
The walls of the apparatus D are provided with exchangeable sections F which are
of less strength than the walls proper of the apparatus or the body thereof. It
will be obvious that in the case of an explosion only the relatively weak portions F will
be destroyed, while the body of the apparatus will not be injured.
The sections F when destroyed may be readily replaced with new ones.
The location of the section F is immaterial; in Fig. 2, the section F is shewn
located in the rear wall of the apparatus.
To close the apparatus, I provide an air-tight door A, which is supported on
swinging arms E, the pivot whereof is located within the section of the apparatus.
These arms support and guide the door in its opening & closing movement. The open
position of the door is indicated in the figures by dotted lines.
Figure 4 shows a form of modification of the described apparatus having two
A being
air-tight doors A, A¹ hinged in the manner herein before mentioned.
thinner than A to serve as the weaker section.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. A vacuum drier or like receptacle for explosives, provided in its walls with
exchangeable sections of less strength than the body of the apparatus substantially as
described and represented.
2. A vacuum drier or like receptacle, provided with a door adapted to close an
opening in the receptacle and swinging arms supporting said door and pivoted within
the section of apparatus, substantially as described.
