and practical and'whichserves'ltc materially improve the eiiiciency andaction of `the device.

Razors of the general type 'cornmonly known as :l safety razors are :characterized .by a frame or holder, which carries a blade and, in. use," the razor istdrawn )overa surface,of the skin thatchas been lathered with .the result thatjthe blade .engages ,thebeard andre'rncv'es git.

. than the 'blade so that itsl longitudinal edges project Aslightly beyond :the cutting edges I4 of the blade. The longitudinal edges or edge portions of the body I0 Vare provided with notches I5 which are uniformly spaced and extend int,o 4 the body at right angles to the edge, leaving fa lthus vrecessing the body the construction will accoximodate a sponge that is comparatively thick yor, ,has considerable body and thus operates to hold a substantial quantity of water.

*out't'he present invention the notches I5 provided inithe yedge vportions ofy the body are extended plurality of teeth-likeparts I6. @In accordanceH with conventional safety razor construction the edge portions of the body or', in other words', the toothed portions thereof, are formed soithatgthe ,teeth present iaconvex or curved surface II immediately ahead ofL thecutting edgesld', the 'construction: being such that the teeth,v generally, curve'4 f orward'from the, cutting 'jedges"asy is clearly `shownin Fig. 2of thedrawing. i'

:razor blade, with'its longitudinal'edges I'lI-'sharpL erred, is arrangedjonrthe bodyjlll' sof'that'jthe edgesfoccur immediately behind 'the lingers I6. The'retainer I2is in'theformlof ajjclamp which s 'jtli'atits edges Ill'are in' proper relati'onlto'-thc toothed edge portions of theb'ody.` The 4construction, provides 'means for securing'fthe re v tainer in place soit properly holds' thebladef `In theform of the invention'under consideration 35' 'them'ounting means forfthe retainerv involves a"s'tem 20 projecting from `the retainerIZ'to pass Al2 2, in'the bodyand into'a threadedopening 23;

However, inV accord-ance Vwith myv invention I prefer, whenmaking a razor to carry 'out the invention to provide definite recesses 35. longitudinally in the blade-facing side of the body 'v inward of the toothed edge portions, as will be apparent from Figs. 1 and 2 of the drawing.' By

'f` Fro'ni vthe foregoing description it willbe apparent'how the'water carrier or sponge A prov'i'ded'byL the present invention'as shown in Fig. V3, may be incorporated in the razor construction as shown' in Figs. `1 and A2,'s`o that'itoccurs between thev bodyland theV blade. lIn use the razor assembled asfshowninFigs. 1"'and 2 is dipped in Water'or is, thoroughly wettedwith t he result thatfthe water carrier A becomes'laden'with wa- `ter.

provide a water carrier A in connection Withthe partsphereinabove described, and vI locate the Y carrier. so that it serves to keep the cutting edgesv ofthe blade wetted or lubricated. The carrier A which fis the distinct, novel element of trie case under'consider'ation thecarrier or sponge isy formed as a rectangular body'corresponding generally, to the shape 'of the blade Il: In the particular'case illustrated the sponge may be of the vsame length as the blade'but is slightly narf rower than the blade so that itV does no tjovery hang or interfere with the cuttingedge"portion"` thereof, An opening 30 is provided in the.

'I'he carrier A' is in this case, as in the other form of the invention, preferably -a sponge and is shaped te nu the space between the body and the blade. A retaining strip 60may be provided to extend longitudinally between the edge portions of the body over the sponge A'- to retain it in position in the cavity portion of the body. In this form of the invention the sponge is shown extended to a point very close to the cutting edge of the blade. tended to the immediate vicinity of the blade so that it actually serves to cooperate with the body in guarding or shielding the cutting edge so that it does not cut the user.

From Figs. 4 and 5 it will be apparent how the retainer l2a can be swung to an open position, i

body Illa at will. When the device is in operation the sponge A' and the blade are arranged as` shown in Fig. 5 and the retainer Ila is in a closed position where its outer end portion bears-down against the blade holding the blade in place, the blade being effectively heldin the desired location against the ears or stops 50.

In the form ofthe invention just described the sponge acts as it does n the case illustrated in Figs. 1 and 2 of the drawing. When in use the razor is thoroughly wetted so that the sponge is loaded with water, and as the shaving operation progresses the water drains from the sponge keeping the cutting edge of the bladezwet, lubricated and ushed clean.

I-laving described only typical preferred forms and applications of my invention, I do not wish to be limited or restricted to the specific details.

herein set forth, but wish to reserve to vmyself any variations or modifications that may vappear to those skilled in the art or fall the scope of the following claims.` Having described myl invention, I claim:

1. A razor of the character described including, a body notched to lform. a toothededgefa blade arranged over the body so its edge is at `the toothed edge of the body, a retainer holding the blade at the body, and an element inserted between the body and blade to carry water and engaging the notched portion of the body.

2. A razor of theVA character described` including, la body, a :blade arranged over the body, means orienting the blade in a predetermined position relative to thebody, a retainer holding the blade at the body, and an element inserted between the body andblade to carry water and oriented by said means.

3. A razor of thechanacter described including, a body, a blade arranged vover the body, parts engaged between the blade and body orienting the blade relative to the body, aretainer holding theiblade at the body, and anelement inserted between the body and blade to carry water and engaged by said parts to be oriented relative to theblade and body.

4. A razor of the character described .including, a body notched to form a 'toothed'edge a blade arranged over the body so its edge is at the toothed edge of the body, a retainer holding the blade at the body, and an element inserted between the body and blade to carry water, there being a'recess in the body `for the reception of the element, which recess extends to the notched portion of 4the body. 1 Y

5. An insert for a, razor including a substantially rectangular thin sheet of sponge to supply water to the blade of the razor.

6. An insert for 'a razor including avsubstantially rectangular thin sheet of sponge to supply water to the blade of the razor, the sheet corresponding generally to the blade of the razor to be retained likegthe blade is retained.
