Application April 30, 1956, Serial No. 581,696

2 Claims. (Cl. 222*191) This invention relates to the art of safety razors and particularly concerns a razor provided with a lather dispenser.

It is a principal object of the invention to provide a razor with a handle for storing lather under pressure and with a blade platform having an outlet for the lather.

It is a further object to provide a safety razor with means for dispensing lather therefrom in advance of the shaving edge of a rabor blade therein.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. 1 is a perspective view of a safety razor embodying the invention.

Fig. 2 is a central longitudinal sectional view of the razor.

Fig. 3 is a sectional view taken on lines 3-3 of Fig. 2.

Fig. 4 is a top plan view of the handle of the razor.

Fig. 5 is an elevational view partly in section of a razor head plate.

Fig. 6 is a sectional view of the razor head plate taken on lines 6-6 of Pig. 5.

Fig. 7 is a perspective view of the razor blade box-like member and blade platform of the razor head.

In Figs. 1 and 2 is shown a safety razor having an elongated handle 11? in the form of a hollow cylinder. At one end the handle is externally threaded. A cap 11 is threaded on the handle. In the cap is an aperture 12. Disposed in the chamber 14 is a coil spring 15. One end of the spring seats on cap 11 and the other end seats on a circular sealing disk or plunger 16. The disk or plunger chamber 1? has an outlet 17 at the top of the handle.

This outlet is threaded to receive the threaded end of a post 21 lodged in the razor head plate 22. The outlet 17 together with a bore 13 in top portion P of the handle define a passage in the handle extending from the upper chamber 19 to the top of the handle.

Post 21 has a longitudinal bore 23 and a diametral bore 24 extending transversely thereto. Diametral bore 24 opens into chamber 25 which is a substantially closed cavity in the razor head box-like member 26.

The razor head box-like member 26 is a generally fiat hollow lather dispenser box-like member with narrow curved sides 23 in which are long narrow opposed slots 29 shown in Pig. 2. On the top of box-like member 26 is a platform or plate 30 with a centrally disposed longitudinal groove 32 and a central aperture 31 as best shown in Fig. 7. The margins 33, 34 of the top of boxlike member 26 together with plate 30 serve as a platform for the flexible blade B. This blade is a conventional type with a central slot through which the central 2,839,224 Patented June 17, 1958 ice 2 ridges 35 on head plate 22 extend. The ridges 35 fit snugly into groove. 32. The ridges 35 shown in Figs. 3, 5, 6 are separated by post 21 on razor head plate 22 and terminate with their ends E just short of the outer edges of the razor head plate.

Valve mechanism for controlling the bore 18 is disposed in the top portion P of handle 10 and this mechaincludes a transverse diametral bore best shown in Fig. 3. In this bore is fitted a coil spring 41 and a pin 42. This pin terminates in an enlarged head 43 which serves as a pushbutton. In pin 42 is a transverse bore 44 which can be brought in alignment with bore 18 by pushing pin 42 inwardly against tension in spring 41. A recess 45 is provided in pin 42 into which a setscrew 46 extends. This setscrew is threaded in the top portion P and serves to limit inward and outward movement of pin 42.

The handle 10 is loaded with a lather S under pressure by first unscrewing the handle 10 from post 21 so that both razor head plate 22 and box-like member 26 are removed. This exposes the outlet 17 and bore 18 at the top of the handle as shown in Fig. 4. It is now possible to load the handle with lather from a conventional areosol type lather dispensing can. The nozzle of the can may be inserted in outlet 17 and when button 43 is pressed a clear passage opens to upper chamber 19. The upper chamber is loaded with lather against the tension in spring 15 which is forced down toward the cap 11 by the pressure on the plunger disk 16. Upper chamber 19 thus enlarges to store the lather while lower chamber 14 diminishes in size. The aperture 12 permits air to escape from lower chamber 14 during the loading step.

When the handle is loaded with lather, the pin 42 is moved outwardly by releasing button 43. This arrangement provides a valve controlled means for loading and dispensing the lather from the razor. The razor head plate 22 and the razor head box-like member 26 with blade B therebetween are then secured on handle 10 by passing post 21 through the blade B and aperture 31. Apertures are provided in the top and bottom of box-like member 26 in registration with aperture 31 for passage of post 21 therethrough. When the razor head plate 22 and the razor head box-like member 26 are seated on the handle it becomes possible to dispense lather in a thin wide sheet-like form from the slot 29 which is in advance of the path of movement of the edge of blade B on the face of the shaver. When button 43 is pressed the lather is released from outlet 17, through bores 23 and 24 into chamber 25. Since the razor is inclined in shaving, the slot 29, adjacent the face, will serve as the lather outlet while the other slot 29 serves as an air inlet to relieve any suction which might develop in chamber 25. The chamber 25 also serves as an expansion chamber for the released lather. The air entering through the slot 29 remote from the face enhances the foaming of the lather in the chamber as it expands therein. The lather leaving through the other slot 29 is readily spread on the face of the shaver as the curved side 20 of the razor head boxlike member 26 is moved over the face. All parts of the razor and handle are so arranged that they can be readily disassembled and washed when necessary.

With the above described razor it is possible to shave ones face immediately after wetting it with lukewarm water. No further spreading of the lather is necessary since the curved edge 20 of the box-like member 26 moving over the face lubricates the skin just ahead of the razor.

While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claims. r Having thus described my invention, what I claim as new, and desire to secure by United States Letters Pat- 'ent is:
