SAFETY-RAZOR.

To all whom z't may concern:

Be it known that we, HENRY THOMAS GILL, of '17 Herbertroad, Bearwood, 'Bir-' mingham, in the county of Warwick,- England, and HARRY Locus, of 57 S camore road, Erdington, Birmingham, a oresaid, engineers, have invented Improvements in Safety-Razors; and we do hereby declare the following to be a full, clear, and exact description of the same.

Our invention comprisesimprovements in safety razors and refers more particularly to that class of such in which a two-edged or a single-edged blade is adapted to be guard plate prevents the free escape of the air removed with the result that the razor 010 and becomes ineflicient in use. I

El ie primary object of the present invention is to overcome this defect and in accordance therewith a series of channels or pas-,-

ges are'provided disposed transversel 1n sa re ation to the guard member. These 0 annels or passages are formed in;the guard member or in the blade or in both the guard member and the blade.

In the accompanying drawings, in which like parts are desi ated by similar reference characters t roughout the several views: v

.Figure 1 represents a front view in eleva- .tion of a safety razor of the Gillettei type constructed in accordance w1th. our invention.

Figs.'2 and-3 are views inperspective of the handle and outer plate member respectively of the razor.

Fig. 4 is an inverted view in longitudinal section, Fi 5 is a plan view looking upward and ig. 6 a view in perspective of the guard member of the razor.

Fig. 7 is a view in perspective of a razor blade.

Referring more particularly to Figs. 1 to Specification of Letters Patent.

guard, the channelsz' then Patented Mar. 9, 1920.

Application filed July 8, I918. Serial No. 243,889.

6 of the drawings, a is the guardwhich may be conveniently cast from aluminium or the like, being made of greater thickness than usual, say three sixteenths of an inch thick. The surface which. contacts with the blade is provided with a series of parallel grooves 6, say eleven, which extend right across the laterally curved surface of the guard a.

These grooves may be conveniently cast on to the guard member. Intermediate between each roove a high or surface portion in the orm of a rib c is ,left against which the blade is clamped, leaving channels through which the hair and soap may freely pass when the razor is being used.

The outer plate member at may be provided with a screwed member (2 and a pair of.upstanding pegs f which engage with holes I in the guard, the screwed member e engagmg with the handle it in well-known manner. a

In lieu of channels or grooves in the guard member, or in addition thereto, shallow grooves or channels 2', see Fig. 7, ma be providedin one or both surfaces 'of to razor blade, such grooves being laterally directed. Ribs j are left between the grooves and form the surface which is clamped against the hair and soap to move away c ear of the cutting edge of the razor. The usual holes is are provided in the blade for positioning and securing the same.

'What we claim is:

1. Ina safety razor, a blade with two oppositely disposed cutting edges, a guard member disposed beneath "said blade and having a series of channels extending between andbeneath said edges, thetops' of said channels being closed by the underside of the blade said channels directly connecting said edges whereby lather removed from the skin by the act of shaving is constrained to pass through said channels to the opposite edge of the blade where it may serve to lather the skin when said opposite edge is employed for shaving and said channels being formed by the spaces between a plurality of ridges upon said guard member, the tops of which ridges being in contact with the blade form supports therefor, said ridges having projecting ends forming teeth at the edges of the guard member.

2. In a safety razor, a blade with two oppositely disposed cutting edges, a guard rmitting the member disposed beneath said bIade and having a series of channels extending be tween and beneath said edges, said channels passing continuously from one edge to the other and being formed by the spaces between a plurality of parallel ridges uponv and integral with said guard member,. said ridges being at right angles tothe edges of the blade the tops of which ridges being in contact with the blade form supports there- 10 g tures.
