3 Claims. (Cl. 21-88)
This invention relates to means to be used in
connection with barbers’ duster brushes wherein
the bristles of the brush may be thoroughly steril
ized each time the brush is used, to thereby over
come one of the greatest objections to the use
of this type of brush. Insofar as I know no
means has heretofore been provided whereby
barbers’ duster brushes may be sterilized to pre
vent the spreading of skin diseases from one
customer to the other. It is, therefore, the ob
ject of my invention to provide a simple, durable
and inexpensive device to- be'used in connection
with a barber’s duster brush wherein the bristles
of the brush will be entirely enclosed when not
15 in use, in an air-tight container, and in connec
tion therewith efficient means for permitting a
volatile sterilization agent such as formaldehyde
gas, to penetrate the container in which the
bristles are enclosed and subject the bristles to
20 the in?uence of said gas, and in connection there
with means whereby the brush may easily and
quickly be placed in operative position.
More speci?cally, it is the object of my inven
tion to provide in connection with a barber’s
brush, a casing slidably mounted on the brush
handle in such a manner as to enclose the
bristles at such times as the brush is not in use,
and in connection therewith a detachable re
ceptacle for containing the sterilization agent
30 which may be easily and quickly placed in posi
tion after the bristles of the brush have been
closed, and further in connection therewith,
means whereby the receptacle will be automati
cally closed before being removed from the cas
35 ing so as to prevent the escape of the gas there
from when the case is not in use.
My invention consists in the construction, ar
rangement and combination of the various parts
of the device, whereby the objects contemplated
40 are attained, as hereinafter more fully set forth,
pointed out in my claims, and illustrated in the
accompanying drawing, in which:
Figure 1 is a side elevation of my improved
device showing the manner in which it is applied
45 to'a duster brush for sterilizing the same, the
slidable casing and the container being shown in
section.
Figure 2 is a side elevation of the same showing
the container removed and the casing moved to
50 position to uncover the bristles of the brush.
Figure 3 is a side elevation of the container for
holding the sterilizing agent, a portion of which
is broken away to show the manner in which the
casing is closed when not in use.

Referring to the drawing I have used the refer
ence numeral ID to indicate the handle of a
duster brush having at each end a number of
spring actuated stop devices I I, the lower end of
the handle IE3 being provided with an enlarged
portion l2 on which the bristles D3 are mounted. 5
Slidably mounted'on the handle i0 is a casing
M which is preferably formed of tubular metal
of the same diameter as the enlarged portion I2,
the upper end of the casing l4 being provided
with an inwardly extending ?ange l5, having a 10
number of semi-spherical recesses iii in its inner
surface adapted to receive the outer ends of the
stop devices ll, secured in the upper end of the
handle I0, when the casing I4 is moved to its
upper position of movement, as illustrated in 15
Figure 2, to serve the purpose of frictionally hold
ing the casing in its elevated position.
Adjacent to the lower edge of the ?ange I5 is
a gasket ll formed of ?exible material such as
rubber, which serves to form an air-tight joint
between the handle and the upper end of the
casing l4. Supported adjacent to the lower side
of the gasket I1 is a second ?ange 18, also pro
vided with a series of semi-spherical recesses l9
to receive the stop devices II located in the
lower end of the handle ID, to thereby provide
means for supporting the sleeve at its extended
position of movement, as illustrated in Figure 1,
to enclose the bristles l3.
The lower end of the casing it is provided with 30
a screw threaded portion 29 adapted to receive
a screw threaded portion 2! of the container 22.
The upper end of the inner surface of said con
tainer is provided with a valve seat 23 adapted to
coact with a valve 24 having a downwardly ex
tending stem 25 yieldably supported in the up
right lug 26 carried by the’ bottom of the con
tainer 22, a spring 27 being provided in said lug
tending to move the valve to closed position.
The upper surface of the valve 24 is provided
with a series of ‘upwardly extending lugs- 28
adapted to be engaged by the lower edge of the
casing M as the container 22 is mounted on the
lower end of the member M, said lug 28 causing
the valve 24 to be moved to an open position 45
after the casing 22 has been mounted on the low
er end of the member it. The portion of the
casing 22 below the valve 24 is ?lled with ?brous
material 29, such as cotton, for receiving a vola
tile sterilization agent such as formaldehyde. It
will readily be seen that the fumes from the ster
ilization agent may enter the casing It and ster~
ilize the bristles 13.
When it is desired to use the brush the casing
22 is removed by simply rotating the same rela

tive to the casing E4 to release the screw thread
ed portions, which at the same time will permit
the valve 24 to move to closed position, thus au
tomatically assuring that the fumes from the
container 22 will not enter the room in which

of ?uids from said container, and means for sup
porting a volatile sterilizing agent in the bottom
of said container.

bination of a duster brush, including a handle
and a brush element, a casing slidably mounted
ilization solution from engaging the bristles of
the brush at any time that the brush should be

the brush is placed. The cotton pad in the bot

trated in Figure 1. The gasket 11 serves to pre
vent any gases from escaping between the mem
ber l5 and the handle l8.
Thus it will be seen I have provided a simple,
15 durable and inexpensive device which may be
used in connection with a barber’s duster brush
such as is now in common use, whereby the cus—
tomer may feel assured that he will not contract
some skin disease from the use of said brush.

I claim as my invention:
1. In a device of the class described, the com
bination of a brush having a handle and a brush
element secured to one end thereof, a casing
slidably mounted on said handle adapted to en
25 close said brush element when in one position
of its movement, a container detachably secured
to the outer end of said casing, said container
having a valve seat, a valve for said seat, yield~
able means for moving said valve to a closed po
30 sition when the container is detached from said
casing, means for automatically moving said
valve to an open position as the container is
placed in position on said casing, means for‘ seal
on said handle to enclose the brush element at
latching the casing either at its upper or lower 10
position of movement, a detachable container se
cured to the free end of said casing, and means
for automatically closing said container on be
ing removed from said casing and for automati
cally opening the container upon being placed in
position on said casing, and a volatile sterilization
agent within said container.
3. In a device of the class described, the com
bination of a cluster brush, including a handle
and a brush element, a casing slidably mounted
on said handle to enclose the brush element at
its outer limit of movement, a yieldable packing
element between the inner end of said casing and
said handle, means for yieldably latching the
casing either at its upper or lower position of
movement, a detachable container secured to the
free end of said casing, and means for automati
cally closing said container on being removed
from said casing and for automatically opening
the container upon being placed in position on
said casing, and a volatile sterilization agent
within said container.
