SAFETY RAZOR Original Filed Oct. 25, 1951 Fi 1 56 52 53 Margie/N i '2 5/ M'TER our 72M AQM vqtiofnqy United States Patent SAFETY RAZOR 7 Harold W. Van Heest, Weston, Mass.

Original application October 25, 1951, Serial No. 253,053,

now Patent No. 2,705,365, dated April 5, 1955. Divided and this application January 10, 1955, Serial No. 480,979

1 Claim. (CI. 30-41) The present invention is a division of my prior and copending application Serial No. 253,053 filed October 25, 1951, now Patent No. 2,705,365 issued April 5, 1955, wherein I have claimed my improved construction as applied to a double-bladed safety razor holder.

In the present application I illustrate and claim my novel and improved construction as applied to a single blade safety razor holder.

Referring to the drawings:

Fig. 1 is a plan view corresponding to Fig. 4 of my said parent application; and

Fig. 2 is a perspective view partly in cross-section, on the line 22 of Fig. 1, corresponding to Fig. 5 of said prior application.

In the construction as shown in my present application and drawings, I have arranged means to hold water and supply moisture adjacent the cutting edge of a single razor blade to thereby moisten the surface to be shaved to improve and perfect the shaving operation and to permit the reservoir of water to be instantly filled by simply holding the holder and its contained razor under a waterfaucet for an instant, which is usually effected during the operation of cleaning the razor from a previous cutting action.

By arranging a plurality of perforations or a narrow slot adjacent the blade-holding end of the blade-holder, a slight trickle of water out onto the edge of the blade is provided so that a single filling of the reservoir will thus supply the moisture for an appreciable time.

As shown in the drawings, Figs. 1 and 2 illustrate my safety razor having the hinged blade clamping cover of the type adapted for a single-edged blade wherein a handle 45 is secured in diagonal association to a guard element 46 formed with an upstanding back flange 47 which carries in hinged association a blade-clamping cover 50, the clamping and releasing of which is controlled by a snap mechanism operated by the finger holds 52 and 53.

2,715,767 Patented Aug. 23, 1955 The cover 50 is constructed with my novel liquid-receiving and -dispensing chamber therein and comprises an outershell and a backing plate 56 united at their sides and bottom edges and spaced apart in upwardly tapering relation by minute ribs 5757. Adjacent the top of such shell 55 is a liquid-receiving opening 58, and slightly above the bottom thereof is a row of liquiddispensing perforations 5959, thus, in combination with the backing plate 56, constituting a liquid-receiving, -storing, and -dispensing chamber, which, of course is divided into separate compartments by the ribs 5757.

When using my safety razor to perform the shaving operation, I hold the same under the hot water faucet for an instant, which is sufiiciently long for the liquid to enter the opening formed by the cutaway portion 58 and to fill up the compartments created by the rib 57, and, thence, to flow thru the perforations 59 onto the edges of the blade 51. I then apply the razor to the lathered face and the moist heat tends to mix with the lather, thereby softening the beard just in advance of the blade edge contacting the same. Then as the razor is cleaned under the faucet between shaving operations, the compartments are automatically refilled with water for the succeeding strokes.

It will be appreciated that the liquid chamber in my razor is of such limited size that the water will flow onto the blades very slowly and will not spill over onto the clothes or apparel of the user.

Thus it will be appreciated that my improved safety razor construction provides means for a liquid-receiving, -storing, and -dispensing chamber which may be quickly filled with water and will feed the water from the reservoir in a slow trickle to the cutting edge of the blade for a more eflicient shaving operation.

Any suitable hinge construction can be employed for the cover.

I claim:

In a safety razor of the kind described employing single-edged blades, and wherein the blade is clamped into operative position by hinged blade clamping means, said means comprising a blade-clamping member comprising an outer shell and a backing plate united at the bottom and sides and provided with a plurality of transverse wedge-shaped partitioning elements therebetween to constitute a number of liquid-guiding compartments Within said member, said outer shell formed with a lengthwise liquid-receiving recess disposed along its upper edge and a plurality of liquid-dispensing ports adjacent its lower edge.
