SHAVING CREAM DISPENSING SAFETY RAZOR Patented July 19, 1932 CHARLES A. MELKA, OF CHICAGO, ILLINOIS SHAVING CREAM DISPENSIN G SAFETY RAZOR Application filed March 13, 1931. Serial No; 522,431.

UNITED STATES PATENT or-area "This invention relates "to 'a shaving cream dispensing safety razor and has for its primary objecttoprovide, in a manner as hereina'fter-set forth,'a safety razor adapted to 5 contain in the handle thereof a supply of shaving cream under pressure which'will be automatically discharged for application to thefface upon'the insertion of a blade into the blade holder for the razor.

m A further'object of the'invention is to pro- ;vide asa'fety razor of the character aforesaid :wliich includesmanually operable means for preventing the discharge of .the shaving creamxby the pressure thereon when desired,

'and which further includes means operating "automatically to prevent any discharge of cream when "the bladeand holderare disassenibled, irrespective of anypressure on the cream.

" With the foregoing andother objects in view, theinvention consists of the novel construction, combination and arrangement of parts as hereinafter morerparticularly described, and as illustrated in the accompanying drawing wherein is shown an embodiment of'the invention, but it is to be understood that the description anddrawing are to be taken. as illustrative and that. the invention is intended to be limited onlyby the scope of the claims hereunto appended.

'In the accompanying drawing in which like numerals are employed to designate like parts throughout the'several views: I

Figure 1 is a perspective .view of a razor in accordance with thisinvention.

Figure 2' is an enlarged sectional perspective view thereof.

Figure'3 is aperspective view of the lather spreading element forming a part of the razor.

Referring to the drawing in detail, the numeral'l indicates the handle of the razor, such handle being of hollow tubular construction provided in spaced relation to its inner end with a partition 2 and having its inner face internally threaded throughout its entire length .on'both sides of thepartition 2. At

the outer'end thereof, the handle '1 is provided witha closure cap Shaving an externallythreaded-annular flange 1 inthreaded engagement with the threaded'inner' fa'ce of i the handle. The cap'8 is provided centrally thereof with an opening 5 through whiohla rod 6 rotatably extends. The 'rod6 lisjof polygonal formation in cross'sectionandjis 5 provided at its outer end with ahead 7 which is fixedly secured to'the rod" in any :suitable manner. Inwa-rdly of-the cap :3, the rod 6 is provided with aradially projecting shoulder 8 to prevent withdrawal of the .rod 69 through the cap 3.

Disposed within the handle l,'inthreaded engagement with the inner face thereof, 'is a piston 9 through which the rod 6 slidably and non-rotatably extends. The piston 9 is provided with a suitable stuffingbox 10 to provide a fluid tight joint' between the piston and rod 6.

Adjacent thepartition 2, inwardly'thereof, N the handle 1 is formed with-a slot'll through which extends a slide valve 12 having an upturned grip portion 13 at its outer end. The slide valve 12 is provided with. an opening 14 which is out of registry with-an opening 15 in the partition 2,when'the grip member 13 is pressed against the outerface of the handle 1, and which is brought into re istry with the opening .15 upon an outward sliding movement of the valve '12. I

Seatedagainst the partition 2is a carrier element 16 which is in ;-the ;form of a plug in threaded engagement with the'handle 1 and havingan opening 17 extending longitudinally thereof and in registry with v the opening 15. The element-16 is suitably grooved in its inner face for slidably receiving the slide valve 12. Formed with or secured to the carrier element116 isia blade holder 18 which includes a pair of resiliently connected plates 19 and 20 whichoonverge towards the free edges thereof and which are adapted to yieldingly grip thereb'etween a blade, such as 21. The plate 20 projects beyond the plate 19 and is provided with. a m serrated edge 22 which providesaguard for the cutting edge of the. blade 21.

Interposed between the holder 18 and handle 1 is a lather spreading element 23 hav--\ ing an opening 2 1 through which'thecar- H rier element, 16 extends. The'latherspreading element 23 is constructed of flexible material, such as semi-hard rubber, and is provided at its edge with an arcuate flange 25 which extends upwardly into abutting relation with the lower plate 20 of the holder 18. The lather spreading element 23 is formed at one edge thereof, between the ends of the flange 25, with a series of massaging nipples 26.

Adjacent the holder 18, the carrier element 16 is formed with a transversely extending opening 27 which communicates with the opening 17 and which opens through the outer face of the carrier element 16 just above the portion of the lather spreading element 23 adjacent the massaging nipples 26. The

0 enin 27 is normall closed b means of a resilient valve-member 28 disposed within the opening 17 and having a resilient shank 29 fixedly secured to the carrier element 16. Slidably and non-rotatably extending through the lower plate 20 of the holder 18,

above the valve member 28, is a pin 30 having an inclined upper face 31 for engagement by the blade 21 when the latter is inserted between the plates 19 and 20. Upon the insertion of the blade 21, the pin 30 is depressed as shown in Figure 2, whereby the valve member 28 is forced downwardly from its normal closure position with respect to the opening 27.

When it is desired to fill the handle 1 with cream, the carrier element 16 is removed from the handle and a tube of shaving cream is threadedly connected with the handle at the inner end of the latter. The head 7 is then rotated in amanner to withdraw the piston 9 towards the outer end of the handle. If desired the handle 1 may be provided adjacent its outer end with an opening 32 to permit the ready escape of air during the withdrawal of the piston towards the outer end of the handle. After the piston 9 has been moved to the outer end of the handle, the cream is squeezed out of its container into the handle, after which the tube is removed and the handle is again connected with the carrier element 16. The head 7 is then rotated in a reverse direction to move the piston 9 toward the partition 2 whereby the cream within the handle is compressed between the piston and partition.

In the use of the razor, lflfiCle, such as 21, is insertedbetween the plates 19 and 20, causing the valve member 28 to be pened by the action of the pin 30. The slide valve 12 is manually moved to a position to bring the opening 1 1 into registry with the opening 15 which permits the cream to escape through the openings 1'? and 27 to the lather spreading element 23 to be spread in the desired manner by moving the massaging nipples 26 over the face. When sufficient lather has been discharged onto the face, the slide valve 12 is closed by pressing inwardly on the grip member 13 with the thumb in order to prevent any further escape of the cream into the opening 17. After shaving, the blade 21 is removed which causes the valve element 28 to close by means of its own tension whereby any likelihood of the cream within the opening 1? leaking through theopening 27 is prevented. Any cream adhering to the lather spreading element 23 then may be rinsed oil by holding the latter under a faucet or the like.

It is thought that the many advantages of a razor in accordance with this invention will be readily apparent, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the size, shape and arrangement of parts may be resorted to, so long as such changes fall within the scope of the invention as defined in the appended claims.
