SANITARY LATHER-MING DEVIGE.

Application filed may 26, 1922. Serial 1%. 563,841.

To all whom itmay corwem:

Be it known that I, JosnrH CAMPANELLA, a citizen of the United States, residing at New York city, in the county of Bronx and 5 State of New York, have invented certain new and useful Improvements in a Sanitary Lather-Making Device, of which the following is a specification.

It is common practice in barber shops to use a single brush for forming the lather on the faces of difierent customers. Such a practice is obviously unsanitary and highly objectionable,'and in many places laws have been passed requiring that the shaving brush and other utensils be sterilized after each operation.

In accordance with my invention, a nozzle is provided through which liquid soap, or other lather-forming liquid, is passed and from which it issues as lather which may be applied to the face of the customer by the hand of the barber, thereby overcoming the objections above referred to.

l have illustrated my novel form of nozzle in connection with a device for containing liquid soap and for forcing the same through the nozzle, which is similar to that illustrated in my prior application, Serial No. 373,586, although it will be understood that the nozzle forming the subject-matter of the present invention is not limited to use with the particular apparatus there illustrated.

My invention will best be understood by reference to the accompanying drawing, the single figure of which is a vertical section, partially in elevation, through a device embodying one form of my invention.

Referring, now, to the drawing, in which all l have illustrated the preferred form of my invention, 1 is a receptacle, preferably, though not necessarily, formed of glass or other transparent material, for containing liquid soap or other lather-forming liquid 2. The upper end of the receptacle is constricted, at 3, to form a neck, which is screwthreaded 'on its outer side, as at l, to receive a cap 5,'which is screw-threaded on its inner side, as at 6, to engage the screw-thread of 59 the neck 3, the cap preferably being formed integral with a head 7, which is preferably formed of a suitable metal, such, for enample, as aluminum. .The head is prov1ded with an extension 8, preferablycylindrical in form, and forming part of the nozzle, wh1ch l have indicated generally by the reference character 9. A washer 10,, of rubber or other flexible material, is preferably interposed between the top of the neck 3 and y the head 7. The head is provided with a passage 11 having a vertical portion communicating with the receptacle and a horizontal portion 12 which passes through a n pple 13 formed on the head 7. A rubber pipe 14 is attached to the nipple 13 in the manner usual in atomizers, a compression bulb 15 being attached to the outer end of the pipe 14. The head 7 is also provided with a passage 16, having a vertical portion communicating with the receptacle 1, and a horizontal portion 17, the horizontal portions of the two passages 11 and 16 preferably being arranged in alignment, as shown,

The vertical portion of the pawage 16 is screw-threaded at its lower end, as at 18, to receive the screw-threaded end of a pipe 19, which preferably extends to a point near the bottom of the receptacle 1. A by-pass or passage 20 connects the horizontalportions 12 and 17 of the two described passages, and is preferably of a small diameter as compared with said passages. The extension 8 on the head is screw-threaded at 21 and receives the screw-threaded end of a tip 22.

The extension 8 is provided with a recess 23,

preferably cylindrical in form, adapted to receive a lather-forming device 2a, which comprises a plurality of lather-forming foraminous members 25 located side by side,

and preferably secured in a cylindrical shell 26, which is received in the recess 23, each of the screens being of a mesh sufficiently large to prevent the liquid soap from clog= ging the same. The ends of the shell 26 are preferably spun over the screens to hold the same in position, the shell and the screens forming a unitary structure. The tip 22 is provided with a recess 27, preferably of the same diameter as the recess 23 in the extension 8, and registering therewith whenthe tip is secured to said extension, as illustrated in the drawing. A second lather-foing device 28 similar to the one already descri is received in the recess 27. A Washer 52% is preferably interposed between a shoulder 30 formed. in the tip and the outer end or the extension 8, and which also engages the lather-forming member 98 on its a side The two lather-forming members are refer: ably spaced apart by a collar 31 w 1e11 1s 4 received in the re'cessof the extension8.

The operation of the device embodyin my invention will readily" be un'derstoo from the foregoing descnptiomand is as follows: By pressin the bulb 15, pressure a is created within t e receptacle 1, which l through the passages 16 and 17 to the nozzle,

. sage acts upon the liquid rising through the forces liquid soap through the pipe 19 and the small diameter of thepagssage 20 permitting suficient pressure to be built up within the receptacle to force the liquid soap through the pipe and thepassage. At the sametime, the air passing through the pasit desirable to use is not clear, but contains a certain amount of rather fine sediment. I have found, in practice, that a single foram inous member of sufficiently fine mesh-to form lather, quickly becomes clogged, and thescreen must then be renewed. By providing a plurality of lather-formingmembers located side by side, i. e., face to face, each of the members being of a mesh sufliciently coarse to permit the soap, including the sediment, to pass, and thereby preclude 1 its becoming clogged by the liquid soap, the

lather-forming member may be used practically indefinitely without becoming clogged, and, at the same time, the plurality of lather-forming members forms a satisfactory lather. l have found, further, that by providing two separate sets of such members, spaced apart in the manner shown, the quality of the lather is greatly improved, as it forms a much more creamy lather than is formed by a single lather-forming member having the same number of foraminous mem-' here as. the two members illustrated combined. I

My theory of what takes place in the lather-forming members is as follows: When the lather-forming liquid, such as liquid soap, mixed with the, incoming air,'passes through the first foraminous member, the soap forms films across the various openings, the edgesof each individual film ad,

hering somewhat to the wires of the foraminous member. The air pressure forces the middle f the film away from the member, thereby forming individual bubbles, and as the mixture of air and liquid passes through the successive foraminous members, the bubmemes bles are finely broken up and finally issue from the nozzle in the cm of a creamy lather. Whatever the correct theory may be, however, as to how the lather is formed, I have found, in practice, that the device made in accordance with my invention, makes a lather that is highly satisfacto WhatI claim and desire to'secure by tters Patent of the United States is:
