Improvements in the Fire Proofing of Safes...
I, HARRY RICHARD ANTCLIFF, of the Vulcan Safe Works, Water Street, City of
Birmingham, in the County of Warwick, Safe Maker, do hereby declare the nature
of this invention to be as follows:-
This invention relates to the improvements hereinafter described in the means for
making safes capable of resisting fire and burglars in a more efficient manner than
heretofore. My invention consists essentially of a composition for filling the fire
proof chamber of the safe whereby the same may withstand great heat, and resist
all attempts of burglars. I make the composition of Portland cement, steel or iron
waste or scraps, and sal-ammoniac, which are incorporated together and moistened
with water. The fire proof chamber is filled up with this composition and is
afterwards placed in an oven or muffle to dry to a solid mass. This said composition
with the walls of the safe becomes one consolidated piece which will greatly resist
fire, and any attempts to drill the safe. may in some cases form a second fire proof
chamber on the outside of the one aforesaid and fill this with the usual fire proof
composition, namely alum and sawdust.

Improvements in the Fire Proofing of Safes.
I, HARRY RICHARD ANTCLIFF, of the Vulcan Safe Works, Water Street, Birmingham,
County of Warwick, Safe Maker, 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 the improvements hereinafter described in the means for
making safes capable of resisting fire and burglars in a more efficient manner than
heretofore.
My invention consists essentially of a composition for filling the fire proof chamber
of the safe whereby the same may withstand great heat and resist all attempts of
burglars. I make the composition of Portland cement steel or iron swarf or scrap
and sal-ammoniac which are incorporated and moistened with water.
The said composition I preferably mix in proportion of cement, three parts of steel
or iron swarf two parts and salammoniac one part. I do not confine myself to these
proportions, I may vary them as circumstances may require to carry my invention
into effect.

page_text: The fire proof chamber is filled up with the above composition and is afterwards
placed in an oven or muffle to dry to a solid mass.
This said composition, becomes one consolidated piece with the walls of the safe
which will greatly resist fire and any attempts to drill the safe.
I may in some cases form a second fire proof chamber on the outside of the one
aforesaid and fill with the usual fire proof composition namely alum and sawdust.
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. The improvements in fire proofing safes consisting of a composition of Portland
or other cement, steel, or iron swarf or scrap, salammoniac moistened with water
substantially as described and for the purpose set forth.
2. The filling of the fire proof chamber of a safe with the composition claimed above
and drying the same to form one consolidated mass with the walls of the safe
substantially as described and for the purpose set forth.
3. The combination with an ordinary safe and fire proof chamber of a second chamber
filled with the composition claimed above for the purpose substantially as set forth.
