page_text: LETTERS PATENT to Frederik Wolff, Candidatus Philosophiæ, Patent Agent
Copenhagen, Denmark for an Invention of IMPROVEMENTS IN THE MANU-
FACTURE OF APPLIANCES FOR SAVING LIFE AT SEA AND OTHER PURPOSES
communicated to me by Sophus Anton Leopold Klixbüll, lieutenant by the
royal marine, Copenhagen, Denmark
PROVISIONAL SPECIFICATION left by the said Frederik Wolff at the Office
of the Commissioners of Patents on the 20th November 1882.
FREDERIK WOLFF, Candidatus philosophiæ, Patent Agent, Copenhagen Denmark,
"IMPROVEMENTS IN THE MANUFACTURE OF APPLIANCES FOR SAVING LIFE AT SEA
AND OTHER PURPOSES (a communication to me by Sophus, Anton Leopold
Klixbüll, lieutenant by the royal marine Copenhagen Denmark)
"
My invention relates to means whereby articles intended for use on board ship
such as mattresses, carpet bags, mail bags, portmanteaus, and the like can be
rendered very buoyant in water.
This is effected by combining with the article to be rendered buoyant inflated
gut previously cleansed disinfected and rendered waterproof the same being
protected by an enclosing case or cases secured within the article to which it is
applied.
The enclosing cases are made waterproof or approximately so and may be
constructed of paste board sewn up or otherwise secured in waterproof cloth and
enclosed in thin wooden boxes but many different constructions of enclosing cases
may be employed. The gut is before inflation cleaned then treated with Carbolic
acid or otherwise prepared in any suitable manner to clean and disinfect the same;
after which it is coated or covered with some suitable substance or substances, such
as gutta percha, paraffine, or the like to render it waterproof.
By the use of gut as described nearly the entire capacity of the enclosing case
can be utilized thus giving a proportionately large displacement in case of
immersion

FREDERIK WOLFF, Candidatus philosophiae, Patent Agent, Copenhagen, Denmark,
"IMPROVEMENTS IN THE MANUFACTURE OF APPLIANCES FOR SAVING LIFE AT SEA
AND OTHER PURPOSES" (a communication to me by Sophus Anton Leopold Klixbüll,
lieutenant by the Royal Marine, Copenhagen, Denmark)
My invention relates to means whereby articles intended for use on board ship
such as mattresses, carpet bags, mail bags, portmanteaus and the like can be
rendered very buoyant in water.
This is effected by combining with the article to be rendered buoyant inflated
gut previously cleaned disinfected and rendered waterproof the same being
protected by an enclosing case or cases secured within the article to which it is
applied.
The enclosing cases are made waterproof or approximately so and may be
constructed of paste board sewn up or otherwise secured in waterproof cloth and
enclosed in thin wooden boxes; but many different constructions of enclosing cases
may be employed. The gut is before inflation cleaned then treated by washing
with carbolic acid or otherwise prepared in any similar manner to clean and
disinfect the same; after which it is coated or covered with some suitable substance
or substances, such as guttapercha, paraffine or the like to render it waterproof.
By the use of gut as described nearly the entire capacity_of_the_enclosing-case-
can be utilised thus giving-a-proportionally large displacement in case of
-immersion.
Fig. 1 of the drawings illustrates a carpet bag with this invention applied
thereto, a is the enclosing case situated at the lower part of the bag and formed of
paste board secured in water proof cloth or otherwise as above mentioned
a represents the inflated gut.
Figs 2 and 3 illustrate a life preserving apparatus, Fig 2 shews the apparatus
folded up and Fig. 3 shews it opened out ready for use-a a are the waterproof
cases containing the inflated gut, b b are cords.
Fig. 4 illustrates a mattress arranged in conjunction with a case a containing
inflated gut.
Having described the nature of the said invention and the manner in which the
same may be carried into practical effect as communicated to me as aforesaid I
would have it understood that what I consider to be novel and original and
therefore claim as the invention secured to me by the hereinbefore in part. recited
Letters Patent is :
1. The use for imparting buoyancy to life saving appliances of gut cleaned,
disinfected, rendered waterproof and inflated substantially as described.
2. The use to prevent loss of life by drowning of boxes or cases having inflated
gut enclosed within them substantially as described.
In Witness whereof I the said Frederik Wolff have hereunto set my hand
and seal this fourth day of May, in the year of our Lord one thousand
eight hundred and eighty three.
FREDERIK WOLFF (L.S.)
