PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Distributing Powders for Medical
and Surgical Purposes.
We, ALFRED ALEXANDER FURST and FRITZ BECKER, both of 3 St. George's
Avenue Aldermanbury in the City of London, Manufacturers' Agents do hereby
declare the nature of this invention to be as follows:-
This invention consists of an improved apparatus for distributing powders, such
as disinfecting powders for example, for medical and surgical purposes. The
apparatus consists of a tube made of any suitable material and adapted to contain
the powder intended to be distributed; this tube communicates at one end with a
hollow collapsible india rubber ball, and terminates at the other end in a suitably
shaped nozzle or jet. Surrounding the said nozzle or jet, and projecting in front
of it is a kind of cage made of plated wire or other suitable material against which
the powder issuing from the nozzle or jet when the ball at the other end of the
tube is squeezed, impinges and is thereby distributed in all directions.
The hollow collapsible ball is preferably provided with an air inlet valve for the
admission of air to the ball as the latter expands after being collapsed, and also
with a valve to prevent the passage of powder from the tube into the said ball.

Improvements in Apparatus for Distributing Powders for Medical
and Surgical Purposes.
We, ALFRED ALEXANDER FURST, and FRITZ BECKER, both of 3 St. George's
Avenue, Aldermanbury, in the City of London, Manufacturers' Agents, 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 consists of an improved apparatus for distributing powders, such
as disinfecting powders for example, for medical and surgical purposes. And in
order that the said invention may be fully understood, we will now proceed to
describe the same with the aid of the accompanying drawing in which Figure 1
represents a longitudinal section of an apparatus constructed in accordance with
the invention, and Figure 2 a front end view of same.
The apparatus consists of a tube, A, made of any suitable material and adapted
to contain the powder intended to be distributed; this tube communicates at one
end with a hollow collapsible india rubber ball B, and terminates at the other end

page_text: in a suitably shaped nozzle or jet C. Surrounding the said nozzle or jet, and
projecting in front of it, is a kind of cage D made of plated wire or other suitable
material against which the powder issuing from the nozzle or jet impinges, (when
the ball B at the other end of the tube is squeezed) and is thereby distributed in
all directions.
The hollow collapsible ball B is preferably provided with an air inlet valve E
for the admission of air to the ball as the latter expands after being collapsed, and
also with a valve F to prevent the passage of the powder from the tube into
the ball.
The powder is placed in the tube B by sliding forward the sleeve G and inserting
the powder through the opening H thereby uncovered. The sleeve G is then slid
back so as to cover the said opening and the apparatus is ready for use; then
when the ball B is squeezed one or more times the powder is blown through the
tube A by the air expelled from the ball and the said powder striking against the
parts of the cage D is thereby deflected in all directions so as to cover the surface
over which it is intended to be spread. It will be understood that the cage D can
be bent to suit the shape of the part in or on to which the powder is to be
delivered.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
First. The improved apparatus for distributing powders for medical and surgical
purposes, which consists of a tube, a collapsible ball and a distributing cage applied
to the outlet end of the tube, substantially as described.
Second. In an apparatus for distributing powders for medical and surgical
purposes the use of a distributing cage applied to the outlet end of the delivery
tube, substantially as described.
