An Improved Powder Insufflator.
STANLEY READ SLATER 54 Dunsmure Road Stamford Hill, N. Stock Clerk
in Wholesale Chemists do hereby declare the nature of this invention to be as
follows:-
My invention relates to an improved construction of powder insufflator.
In powder insufflators as at present constructed the glass bottle which holds the
powder is very large and unwieldy and holds a far larger quantity of powder than
is required for ordinary use. There is further no means of protection for the glass
bottle and in the event of a person wishing to diffuse a medicated powder of a
different substance to that which is already in the bottle the powder must be turned
into a receptacle & the bottle cleansed before the powder required for immediate
application can be put in or else a person must carry a number of large bottles
about with the different powders which he or she may require.
To avoid all difficulties indicated above I first employ a cylinder of glass
celluloid or other material for holding the powder which can be drawn in at each
end or only at one end and mounted at either or at both ends by a collar of metal
or other material or the cylinder may be of the same bore from end to end and
may or may not be mounted at either or both ends. In this powder vessel I
fix or have made adjustable at either one of the ends of the powder vessel a
straight or curved tube of glass or other material and at the other end I place
a small cap or cork which may be adjusted when required for putting in and
applying the powder to be diffused. This vessel may conveniently be placed
with one or more vessels containing the same or different powder in a case which
can easily be carried about when required.
To hold this powder vessel in position I employ two (2) small cylinders of metal
or other material placed at a convenient distance apart to allow of the powder
vessel being inserted between them & I connect these cylinders by one (1) two (2)
or more rod or rods of metal or other material which also serves or serve as a
protection for the powder vessel.
In one cylinder I place a spiral or other spring which is kept in position at the
end furthest removed from the opposite cylinder by a curved or a straight tube
which may be either fixed or removable and through which the wind is conducted
to the powder vessel from the usual rubber ball or other apparatus for generating
a current of wind and at the end nearest the same opposite cylinder just referred
to I place a flanged screw ring which admits of one end of the powder vessel being
which
placed through it which end abuts against a washer cap
place over the end
of the spiral or other spring described above.
The end of the other cylinder nearest the cylinder which contains the spiral or
other spring I make of a convenient size to admit the opposite end of the powder
vessel to that end to which the small pipe inside the powder vessel is connected and
at the end of the same cylinder that is furthest removed from the cylinder which
carries the said spring I fix or have made adjustable a tube which may be either
a curved or a straight tube for conducting any medicated powder which may be
required for use to the affected part.

STANLEY READ SLATER 54 Dunsmure Road Stamford Hill N. in Instrument
Department of Wholesale Chemists 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 :-
My invention relates to an improved construction of powder insufflators the object
of same being to enable the operator to change an insufflation very readily & without
loss of powder used. It also relates to the powder vessel in such a manner that it
can be readily inserted in the cradle of the insufflator.
My invention is illustrated in the accompanying drawing in which,
Fig. 1 is a general view of my improved powder insufflator with the powder
vessel or cylinder in position in the cradle.
Fig. 2 is a longitudinal section of same.
Fig. 3 is an elevated section of my powder cylinder or vessel.
In powder insufflators as at present constructed the glass bottle which holds the
powder is very large and unwieldy and holds a far larger quantity of powder than
is required for ordinary use, there is further no means of protection to the glass
bottle, and in the event of a person wishing to diffuse a medicated powder of a
different substance to that which is already in the bottle, the powder must be first
turned into a receptacle and the bottle cleansed, before the requisite powder for
immediate application can be put in, or a person must carry a number of bottles
containing different powders about with him, to suit his requirements.
To obviate the difficulties indicated above, I first employ a vessel of celluloid,
glass, or other material suitable for holding powders, which I reduce at each end,
as in Fig. III at A* and Ab, or, may be only reduced at one end, or the cylinder
may be of the same bore throughout.
At the reduced end, or at the end A* of the powder vessel, I fix a curved or
straight tube B perforated in one or more places, to allow of the air being forced
into the vessel, and, on the neck or mouth of said vessel, at the opposite end to that
just referred to, I place a cap C which may be adjusted when required for putting
in or ejecting powders, (for portability the powder vessel can conveniently be placed
in a case with one or more vessels containing different powders, which may be
inserted in the insufflator at will).
To hold said powder vessel in position I employ two small perforated cups D & E
of metal or other material and fix them at a convenient distance apart by one or
two (or more) bent or straight rods F or G, or F & G of metal or other material
to allow of the powder vessel being inserted between them. In the perforated
cup E I place a spiral or other spring H which I surmount by a perforated disc J
intercepted by a leather or other washer K the whole of which is held in position
by a screw retaining cup L having a perforation sufficiently large to allow of the
end A of the powder vessel being inserted. The object of same being to provide
means for a quick interchange of powder vessels. The end A* of the powder
vessel is pressed against said metal disc J forcing the spring down while the
neck A of the powder vessel is adjusted to the opposite mount D. The powder
vessel being subsequently released is retained in position by the reaction of said
spring forcing the neck or mouth of said powder vessel against the mount D.
At the exterior end of the cup E I fix a curved or straight tube M having a
screw at its unattached end connected with a valve chamber and india rubber ball
or other apparatus for generating a current of wind, and through the perforation
at the exterior end of the cup D I place a straight or curved delivery tube N
which may be directed at will to the affected part or parts.

page_text: 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. A cylinder; comprising reduced ends.
A bent tube, attached to one of the reduced ends.
A screw adjusting cap screwed on the neck of the other reduced end, substantially
as described.
2. A cylinder comprising reduced ends.
A cradle comprising a metal cup, and
A spiral spring, metal disc and leather washer retained in said cup by a perforated
screw nut made to receive the small end of said powder vessel.
A wind conducting tube connected to the exterior end of said cup.
A cup made to receive the reduced end or neck of the powder vessel and
provided at its exterior end with suitable means for carrying a delivery tube.
Two bent rods attached at their extremities to said cups, at a convenient distance
apart to allow of the powder vessel being inserted and retained between them,
substantially as described.
