Pooley Application July 16, 1936, Serial No. 90,916

3 Claims.

This invention relates to means to be used in connection with barbers duster brushes wherein the bristles of the brush may be thoroughly sterilized each time the brush is used, to thereby overcome 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 prevent the spreading of skin diseases from one customer to the other. It is, therefore, the object of my invention to provide a simple, durable and inexpensive device tobe'used in connection with a barbers duster brush wherein the bristles of the brush will be entirely enclosed when not in use, in an air-tight container, and in connection 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 the influence of said gas, and in connection therewith means whereby the brush may easily and quickly be placed in operative position.

More specifically, it is the object of my invention to provide in connection with a barbers 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 receptacle for containing the sterilization agent which may be easily and quickly placed in position after the bristles of the brush have been closed, and further in connection therewith, means whereby the receptacle will be automatically closed before being removed from the casing so as to prevent the escape of the gas therefrom when the case is not in use.

My invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated 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 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 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 reference 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.

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 flange l5, having a 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 Figure 2, to serve the purpose of frictionally holding the casing in its elevated position.

Adjacent to the lower edge of the flange I5 is a gasket ll formed of flexible 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 flange 18, also provided 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 to enclose the bristles l3.

The lower end of the casing it is provided with 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 container is provided with a valve seat 23 adapted to coact with a valve 24 having a downwardly extending stem 25 yieldably supported in the upright lug 26 carried by the bottom of the container 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 after the casing 22 has been mounted on the lower end of the member it. The portion of the casing 22 below the valve 24 is filled with fibrous material 29, such as cotton, for receiving a volatile sterilization agent such as formaldehyde. It will readily be seen that the fumes from the sterilization agent may enter the casing It and sterilize the bristles 13.

When it is desired to use the brush the casing 22 is removed by simply rotating the same relative to the casing E4 to release the screw threaded portions, which at the same time will permit the valve 24 to move to closed position, thus automatically assuring that the fumes from the container 22 will not enter the room in which the brush is placed. The cotton pad in the bottom of the container serves to prevent the sterilization solution from engaging the bristles of the brush at any time that the brush should be supported in any other position than that illustrated in Figure 1. The gasket 11 serves to prevent any gases from escaping between the member l5 and the handle l8.

Thus it will be seen I have provided a simple, durable and inexpensive device which may be used in connection with a barbers 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 combination of a brush having a handle and a brush element secured to one end thereof, a casing slidably mounted on said handle adapted to enclose 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, yieldable means for moving said valve to a closed position 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 sealing the other end of said casing to prevent escape of fluids from said container, and means for supporting a volatile sterilizing agent in the bottom of said container.

2. In a device of the class described, the combination of a duster 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, 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 automatically 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.

3. In a device of the class described, the combination 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 automatically 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.
