LATHER-FOBMING DEVICE.

Application tiled July 29, 1922. Serial No. 578,401.

To all `whom if 4may concern.

Be it known that: I. ROBERT HUDSON IVAGEP., a citizen of the United States, residing at Jersey City, in the county of Hudson and State of N ew Jersey, have invented certain new and useful Improvements in a Lather-Forming Device; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in devices for forming lather for shaving purposes and has reference more particularly to a device in which air is injected into a chamber containing a saponaceous liquid, the suds being then forced through means for breaking the bubbles and condensing their soap content into a smooth lather,

prior todischarge for use. A device of this character is shown by my pending U. S. application, Serial No. 544,059. filed Mar. 15, 1922, but the present invention aims to provide improved means for condensing the soap content of the generated bubbles, as well as to provide an improved arrangement, whereby the bubbles or suds will be effectively genera-ted, regardless of the size to which the cake of coap has worn.` The method or process described herein, is claimed in my co-pending application Serial To. 699,133 filed March 13, 1924 which is a division of application Serial No. 544,059.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawings.

Figure 13 is a detail perspective show-k ing the preferred manner of closing the water inlet opening of the suds generating chamber.

Figure` 14 is a view similar to the upper portion of Figure 4 but illustrating a slightly different form of construction.

In the drawings above briefly described,l

lwith ribs 4to hold the soap cake against rotation thereon. The platform 3 is spaced above the bottom of the receptacle 1 and I provide means for supplying air under pressure to the Space beneath said platform, so that air will be supplied to the water around the edge of als the platform 3 and soap cake :2 thereon.

In the preferred form of construction, the lower side of the platform 3 is provided with a centrally disposed'depending neck 5 threaded-into' the enlarged upper end of an air supply passage 6 which is formed in the bott-om portion of the receptacle. The neck 5 is formed with a passage 7 communicating with the delivery end of the passage 6 and a plurality of air discharge ports 8 lead `from said passage/7 through the neck to supply air in radial jets beneath the soap supporting platform 3. In the preferred from of construction. 'the lower side of this platform is provided wit-h a plurality of curved substantially radial ribs 9 located between the ports 8 and defining passages of such shape and to impart a whirling motion to the water within theyreceptacle 1, when air under pressure is yforced into the device through the passage Ywhich pass entirely through the platform 3. Thus, by the time the soap `cake has worn down to such an extent as to revent the ei'ective formation of soap bub les byl whirling of the water around the cake, jets of air and water Will be forced upwardly through the ports 11 against the Vcake which then assumes substantially the shape shown by the dotted lines in Fig.

2. Thus, the soap cake can be entirely used and no waste will thereforeccur.

The meeting portions, of the

passages

6 and 7 are flared to form a valve cage and with a dependin seat within which a ball check 12 is located so as to prevent .any liquid from running into the passage 6 from the'receptacle 1, while permitting air under pressure from the bulb 10 tovpassfreely into said receptacle. To pre vent upward closing y of the check 12, any suitable provision may be made, such as forming grooves 13 in the wall of the pas-pl sage 7 at its flared lower end.`

For the purpose of filling thereceptacle 1 with water, I provide it with a suitable lilling neck 14 having a` removable closure 15 which is preferably heldin place by means of a pin .16- and bayonet slots 17, an appropriate gasket 18 being interposed between the closure and the neck to form a liquid tight connection. Attention ma lhere be directed to the fact that the nec 14 constitutes an overiow for the receptacle 1, preventing filling of the latter to an undesirable extent. The location of this neck insures that suiicient water shall not be supplied to the receptacle 1, to run from either'the upper or lower end of the latter, should it be accidentally tilted or laid upon one side. This is due to the fact that the level of`liquid in the receptacle will not reach as'high as the passage 7 or the central outlet from the upper end of the receptacle 1, if the latter is ina position at an angle or on one side.

The numeral 20 designates a removable cap threaded upon the upper end of the receptacle 1 and provided with a lather outlet spout 21. This cap contains final suds condensing means and preliminary condensingmeans are located within-a hollow partitlon which separates the receptacle from the ca In the present showing, a disk 22A is c amped between the receptacle and the cap 20, said disk being provided annular ange 23 closed at its lower en by a disk 24 which is ybein riphery. The edge of Athis disk as here shown, is provided with an upwardly ex- ,l

tending rib 26 upon which a screen 27 rests. A second disk 28 rests upon the screen 27 and is provided with a central aperture 29. A second screen 30 rests upon the upper side of the disk 28 and is held against the same by a spacing ring 31 bearing against the upper side of said screen 30. Between the ring 31 and the late 22, a third screen 32 is positioned, w ich screen extends across the central outlet opening 33 with which the plate 22 is formed. A spring ring 34 is preferably provided to hold the several parts 24-32 within the flange `23 and it will be seen that removal of this spring ring, will permit easy disassembly of the initial -suds condensing means for cleaning purposes. The ring 31 and disk 28 serve as spacing members between the adjacent screens.

The capy 20 is provided with a central depending sleeve 35 which registers at its lower .end with the opening 33, said sleeve formed with an outlet opening 36 placing it in communication with the space between said sleeve and the peripheral wall of the cap. Extending across this space between the openin 36 an the spout 21, is a partition 37 w ich forces the suds discharged through the opening 36, to travel entirely around the interior of the cap before it is. discharged through the spout ,21. During this travel, a number of screens 38 are encountered and these screens act to further condense the soap content of the partially condensed suds, so that a thick smooth lather 'fs produced for expulsion through the spout 21.

As shown most clearly in

Figuresr

6, 7, 11 and 12, each screen 38 is preferably mounted on a rigid sheet metal frame 39 andthe cap is providedwith vertical guide formed withy grooves 41 receiving the upper portions of said frames.A

Tooperate the device, a cake of soap is pressed downwardly upon the platform 3 and the plate 22 with its condensing means and the cap 20, are again secured in place. The closure 15 is now removed and the receptacle 1 isl filled with water to the extent permitted by the neck 14. When this closure Ais again aplied, the device is in readiness'for use.` peration of the bulb or'the like'lO will now cause discharge of air under pressure into the receptacle- 1 around the cake 2, therebyforming soap bubbles which are forced out through the

openings

25, 29 and 33, and the interposed screens, Thus, the .soap bubbles` are broken up and their soap content isreduced t0 a lather which is discharged through the opening 36 and must pass through the screens 3S before reaching the discharge spout 21, the result being thatl further condensation takes place and when the lather is finally discharged, it vis in the form of a thick smooth cream of proper consistency for shaving. rllhis lather may be caught in the hand and applied to the face directly. sothat the use ot' an unsanitary brush is not necessary.

' l have found in actual practice, that the soap suds in being pressed by the action of the bulb. through the several extremely tine screens within the ange. 23 will pulsate them and permeate between these screens and the adjacent disks and will ooze through the entire areas of said screens instead of only through the portions extendingover the several openings. Thus. a. thorough breaking up of the soap suds is produced which insures a perfect lather.

In view of the tact that excellent results are being wbtaincl 'from the exact details shown and described. these details may well be followed. but it is to be understood that within the scope of the invention as claimed, numerous minor changes may be made. It

will be understood that any suitable pro-Vy vision may be made for'providingan air tight or liquid tight jointl wherever desired. The numerals l5 in Figures 2. l and 1st, designate suitable ground joints for this purpose.
