Improvements in Disinfecting and Fumigating Apparatus.
I, GEORGE GROSVENOR CROSBY, of 2 Wall Street, in the City, County and
State of New York, United States of America, Inventor, do hereby declare the
nature of this invention to be as follows:-
This invention relates to devices for distributing disinfectants, the object being
to provide an efficient durable and portable device of this character, and the inven-
tion consists of a receptacle for a disinfectant and means for forcing a current of
air through the same and subsequently ejecting the impregnated air.
While I have stated my invention for use with a disinfectant, it is to be
understood that it may be put to other uses, such, for instance, as ejecting
perfumed air.
My invention may be used in a number of places, such as a sick room,
hospitals, etc., and as it may be conveniently packed in a travelling case,
it may be used by a traveller in a hotel room to disinfect the air arising
from stationary wash-basins, or similar places.
The disinfectant device embodying my improvements consists of a casing
having a hinged cover, provided with fastening clasps or similar devices, and
with a handle by means of which the device may be carried in the hands.
It also consists of a tray for receiving sub-trays, which contain the disinfectant.
Three of the sub-trays and the tray are provided with partitions, but a
greater or less number of sub-trays may be employed and the partitions
may be omitted without departing from the spirit of my invention.
The side walls of the sub-trays are perforated and are inclined downwards
and inwards, so that air may circulate freely.
The partitions are provided with openings, and the end walls of the tray
are also provided with openings; the opening in one end wall registers with
an opening or inlet in one end wall of the casing, and the opening in the
other end wall of the sub-tray registers with an opening in a partition in the
casing.
The openings in the partitions are preferably arranged in a zigzag row.
The sub-trays contain an absorbent material, such as sponge or cotton,
which may be saturated with any desired disinfectant.
To prevent the entrance of dust or dirt through the inlet, I may provide
it with a screen, and the entrance of the air draft may be regulated by more
or less opening the damper having connection with a rod hung in suitable
bearings within the tray, and having an outwardly projecting hand piece. The
"damper may be retained at any desired angle by a retaining device, as a spring
plate.
I will now describe a means for forcing air through the disinfecting material
and ejecting the same, and it consists of a suction fan and blower which may
be rotated by any desired means, such as by an electric-motor, firmly secured
within the casing. The fan is mounted on the shaft of the electro-motor, and
is located near the inner side of the end wall of the casing, and this wall is
provided with an outlet opening.
The source of electricity is a battery, located in the casing beneath the tray, and
is secured in place by means of tie bands. From one element of the battery a wire
extends to a brush of the electro-motor, and a wire extends from the other element
of the battery to an exterior switch. From one contact of the switch a wire
extends to the other brush of the electro-motor.

page_text: By means of the switch, the electric current may be turned on at will to set the
fan in operation, and the fan may be kept in operation for any desired length of
time.
In operation the device is placed in any desired position, the damper regulated
and the current turned on. Outer air will be drawn forcibly through the
disinfecting material and forcibly ejected through the outlet.

Improvements in Disinfecting and Fumigating Apparatus.
I, GEORGE GROSVENOR CROSBY, of No. 2 Wall Street, New York City,
County and State of New York, United States of America, Electrician, 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 devices for distributing disinfectants, the object being
to provide an efficient, durable and portable device of this character, and the
invention consists of a receptacle for a disinfectant and means for forcing a current
of air through the same and subsequently ejecting the impregnated air.
While I have stated that the invention may be used with a disinfectant, it is to
be understood that it may be put to other uses, such, for instance, as ejecting
perfumed air, &c.
The invention may be used in a number of places, such as a sick room,
hospitals, etc., and as it may be conveniently packed in a travelling case, it
may be
used by a traveller in a hotel room to disinfect the air arising from stationary wash-
basins, or similar places.
In the accompanying drawing,
Figure 1, is a perspective view of a disinfecting device embodying my improve-
ment.
Figure 2, is a longitudinal vertical section thereof.
Figure 3, is a transverse vertical section on the line 3, 3, of Figure 2.
Figure 4, is a top plan view with the cover of the casing open.
Figure 5, is a longitudinal vertical section of a tray for containing disinfecting
material.
Figure 6, is a transverse section thereof.
Referring by letter to the drawing, A, designates a casing having a hinged
cover A', provided with fastening clasps or similar devices a, and with a handle a'
by means of which the device may be carried in the hands.
B, is a tray for receiving sub-trays B', which contain the disinfectant. I have
shown three of the sub-tray's B', and the tray B, is provided with partitions b, but
a greater or less number of sub-trays may be employed and the partitions b, may be
omitted without departing from the spirit of my invention.
The side walls, of the sub-trays are perforated and are inclined downwards
and inwards, as shown, so that air may circulate freely.
The partitions, are provided with openings 62, and the end walls of the tray
are also provided with openings; the opening in one end wall registers with an
opening or inlet 3, in one end wall of the casing A, and the opening in the
other end wall of the tray registers with an opening in a partition a*, in the
casing A.
The openings in the partitions b, are preferably arranged in a zigzag row, as
shown.

page_text: The sub-trays contain an absorbent material a³, such as sponges or cotton, which
may be saturated with any desired disinfectant.
To prevent the entrance of dust or dirt through the inlet 63, I may provide it
with a screen, and the entrance of the air draft may be regulated by more or
less opening the damper a, having connection with a rod a, hung in suitable.
bearings within the tray B, and having an outwardly projecting hand piece 5.
The damper may be retained at any desired angle by a retaining device, here.
shown, as a spring plate aⓇ.
I will now describe a means for forcing air through the disinfecting material and
ejecting the same.
C, designates a suction fan and blower which may be rotated by any desired
means. I have here shown an electro motor C¹, firmly secured within the casing A.
The fan C, is mounted on the shaft c, of the electro-motor, and is located near the
inner side of the end wall e', of the casing A, and this wall is provided with an
outlet opening c².
A source of electricity, here shown as a battery D, is located in the casing A,
beneath the tray B, and is secured in place by means of tie bands d. From
one element of the battery a wire d', extends to a brush of the electromotor, and
a wire d', extends from the other element of the battery to an exterior switch D'..
From one contact of the switch a wire d³, extends to the other brush of the
electromotor.
By means of the switch D', the electric current may be turned on at will to set
the fan C, in operation, and the fan may be kept in operation for any desired length
of time.
In operation the device is placed in any desired position, the damper a, regulated
and the current turned on. Outer air will be drawn forcibly through the disinfecting
material and forcibly ejected through the outlet e².
