SAFETY RAZOR.

Application filed January 27 1926. Serial No. 84,220.

The razor of the present invention combines all of the safety of an ordinary safety razor with all of the ready manipulability and convenience in shaving at awkward angles of the straight razor.

a straight razor made safe with the head of the razor so adjustable relative to the handle that any desired shaving angle may be obtained and the usual barber stroke permitted.

An object of the invention is to provide a safety razor combining the above noted advantages with simplicity and ruggedness of construction.

A further object is to provide a safety razor from which the blade may be readily removed and replaced for purposes of cleaning, honing and sharpening, etc.

A still further object is to provide a safety razor in which the shaving head is automatically locked inall of its various adjusted relations to the handle, and which may be manufactured. with comparative economy.

With the above noted and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described and pointed out in the claims. r I

The invention may be better understood from the following description in connection with the accompanying drawings, wherein- Fig. 1 is a plan view of a razor embodying the present invention. I

Fig. 2 is an edge view of Fig. 1.

Fig. 3 is a plan View of the blade holding guard plate disassembled-from the handle and with'the blade and spring removed.

Fig. 4 is a fragmentary view in side elevation of the handle.

Fig. 5 is a transverse sectional view on the line 55 of Fig. 3.

Fig. 6 is a fragmentary elevational view of the handle taken at right angles to Fig. ft.

' In the drawings, I have used the reference character 10 to designate the blade supporting guard plate including a flat plate portion 11 of approximately segmental shape integral at its fiat side with angular disposed blade guard portion 12, the latter being formed at its guard edge with a source of guard teeth 13. The side edges of the blade guard 12are rolled over or turned inwardly at 1.4 to define a receiving channel 65 15 for the edges of a blade 16. i

The cross sectional shape of the blade may It is in effect relative to the handle.

be best seen from Fig. 5 where it will be noted that the blade is ofa cross sectional shape closely corresponding to the shape of an ordinary hollow ground straight'razor. The blade ends lie flatly under the members 14:, and forward movement of the blade is limited by a stop 14* turned downwardly from the forward or outer ends of menibers 14L.

The razor handle 17 may be of various shapes, but in any event includes at one end an angularly'disposed stud portion 18 carrying a polygonal rigid blade clamping head 19. The stud 18 projects from a flat shoulder 20 at the end of the handle.

' The plate portion 10 is formed with an open ended slot21 adapted to receive the neck 18. hen this near is accommodated by the slot 21, shoulder 20 and head 19 effectively prevent pivotal movement of the plate 11 in any direction except in a plane parallel to the plane of the shoulder 20. The handle will thus be disposed at all times in substantial parallelism with the shaving head. A fiat spring 22 having its ends suitably removably anchored as by the recessed or channel lugs 23 rising from the plate 10, bears against the head 19 and forces the latter against the rear side of blade 16, thereby forcing the blade home under the keepers 14.

The head 19 might be'made of various polygonal shapes but I have found the most desirable shape to be hexagonal with the lateral faces of hexagon disposed eccentrically relative to the neck or pivotlS.

These faces have been numbered 19, 19 19, 19 19 and 19 The face 19 is disposed at the greatest distance from the pivot 18 and the face 19 is disposed closest to the pivot. WVhen inserting the blade, handle 17 is rotated until the face 19 is engaged by the spring 22 which forces the neck or stud 18 against the inner end of the slot 21. position ample room is provided for insertion of the blade due to the relatively short distance between the center of the stud 18 and the face 19 hen any of the other five faces of the head 19 are engaged by the spring the opposite face of the stud will be spring urged into clamping relationship with the blade back as will be readily understood. Y

virtue of this construction the shaving be adjusted at livediderentangles The adjustment is head may In this ltl effected in every instance simply by rotating the shaving head relatively to the bandle. In every instance, the spring acts automatical y to loclt the head in the desired position of adjustment relati eto the "handle.

From the foregoing description, it will be evident that the device of the present invention may be used substantially in the manner of a straight razor to obtain a'barbers stroke, and due-to the wide and varied range of adjustments possible, permits anyone skilled in the use of a straight razor to shave with ease and expedition.

If the user desires the ordinary safety razor strolie this may also be obtained by proper adjustment of theshaving head relative to the handle.

lVhile I have illustrated one of the pre ferred embodiments of the invention, it will be understood that nulneious changes and alterationsmight bemade 1n the general form and arrangement of parts'vdescribed,
