Definitions

• This .invent-ion relates to an improvement v in razors, and one of the objects thereof is to provide a simple 'and efficientdevice in which a thin, replaceable blade is used and which can be used in the same manner as a razor of f vthe ordinary type.
• a further object of the invention is to rovide a thin, fiat, detachable, double-e ged blade, the blade being stiH enough to retain a straight edge.
• a further object of the invention is to provide a' device similar in form to an ordinary razor in which a'double safety guard is employed for the purpose of obviating the necessity of shifting the guard from one side of the blade to the other.
• a further object .of the invention is to ⁇ provide a device which may be used either as a safety razor or as one 'of the ordinary type l with an exposed blade.
• Figure 1 is a plan view, vpartly in section, of a device 'embodying' the invention
• Fig. 2 is a side elevation of the .structure shown in Fig. 1;
• a thin blade 1 which may be provided with two cutting edges 2, as
• the blade 1 is ilat
• a support for the blade and this support ' may vary widely in struc'- ture.
• a support 3 is provided which is narrower 'than the blade and which extends throughout its length. extended from one end of the'support 3 and A shank 4'is' this shank 4 is pivoted at 5 to a handle 6 of any suitable structure.
• the shank 4 lies in planes ilset from the planes of the support 3, and in' lanes coincident with the planes of the blagle, as is clearl shown in Fig. 1.
• a c :imp is provided for securing the blade to the support and this clamp may nary widely in form. As shown, a substantial y being narrower than the blade and exten( ing through# out its length.
• the clamp iis provided with means engaging the support and having a limited sliding movement thereon to lock the blade'between the clam and support, and this means may vary wi ely in construction. In the best constructions and as shown, this means has a limited, longitudinal, sliding movement on the support and consists of a headed stud 8 which engages a shouldered countersunk slot 9 in the support 3 befoie referred to, the shoulder being cut away at one end of the slot, as is clearly shownin Figs.
• the b ade 1 is provided with erforations v10 and 11, the perforation 10 eing so located in the blade that theheaded stud 8 will pass through' it and into the slot 9 before referred to.
• Means are provided for protecting one edge ol the blade, when the other is to be exposed for use as in an ordinary razor. ln the modified form of clamp, illustrated in Figs. 4' and 5, this means consists of an extension 14 projected from one side of'the clamp 7. the edge of the extension being ribbed at 15, the rib extending over the edge ot the blade,
• the device mayY be provided with means whereby it is converted into a safety razor and this means may vary widelyv in form. ln the best constructions and as shown, the clamp 7 is rovided with a. series of teeth lo projecting rom both sides ot the clamp and extending beyond the edge of the blade, as is clearly shown in Figs. .2 and 3. These teeth do not. contact with the cutting edges 2 of the blade.
• Means are provided for protecting thc corners of the blade when the ⁇ double safety guard is used and this means is carried b v the clam and lies in the )lanes ofthe blade.
• this means eonsists of ribs 17 formed on the. end teeth projecting from the clamp 7, the ribs being bent to intersect the planes of the blade, as is clearly shown in Figs. 2 and 3.
• ⁇ Means are provided for assisting in the removal of a blade from the clamp and this means may vary in construction.
• the clamp 7' is provided with arecess 1H at one end, the purpose ot this recess being to Yierinit the insertion of a tinger to litt the )lade from the clamp.
• a segregable clamp provided with a headed stud engaging a shouldered countersunk slot in the support and having a limited sliding movement inthe slot to lock the blade between the clamp and support, substantially as described.
• a razor the combination with a flat detachable perforated blade,of a support for the blade, and a scgregable clamp provided with positioning studs passing through perfoi-ations of the blade and with a headed stud passing through one of the perforations of the blade and engaging a shouldered counter'- sunk slot in the support and having a limited sliding movement therein to look thc blade between the clam and thc support, substantiall)r as describe 4.
• the combination with a flat detachable perforated blade, of a support for' the blade, and a segregablo clamp provided with positioning studs passing through and projecting bevond perforations ot the.
• clamp provided with blade-positioning studs passing through and projecting beyond pcrforations of the blade and with a headed stud engaging a shouldered counter sunk slot in the support and having a limited sliding niotf'emciit thereon to loclt the blade between thc clamp and support thc opposite edges of the clamp being provided with teeth to form a double safctiY guard and the corner teeth being bent to intersect the planes of the blade to protect the corners thereof. sillistantially as described.
• a razor the combination with a. perforated blade, of a support for the blade, a clamp, incans for positioning the blade between the support and clamp, independent means passing through the blade for holding thc su )port and clamp together, and a shank extended from ont ⁇ end of the support and living in planes co-incident with/the planes of tbe blade, substantially as described.
