A CQRIPORATION.
SAFETY RAZOR.
Application filed May 19, 1923. Serial No. 540,096.
. My invention relates generally to razors, and more particularly to a razor of the safety type, the principal objects being to generally improve upon and simplify the construction of existing forms of safety razors; to provide a safety razor having a blade holding head or frame that is curved lengthwise in order that it may be conveniently used on curved portions of the body, for 1a instance, the axilla; further to provide ina safety razor a curved head or blade-holding body that will firmly clamp and retain the flexible-blade inproper curved position; and further to provide a structure that may be functions.
With the foregoing, and other objects in view, my invention consists in certain novel 20 features of construction and arrangements of parts, which will be more fully hereinafter described, and illustrated in the accompanying drawings, in Which,-
Fig. 1 is a perspective view of a safety razor of my improved construction;
. Fig. 2 is a perspectiveview of the upper or top plate that forms a part of the head or blade holding frame;
Fig. 3 is a vertical section taken approximately on line 33 of Fig. 1. Fig. 4: is a plan view of the lower plate of the head or frame.
Fig. 5 is a plan view of oneof the blades that is used in my improved safety razor.
Fig. 6 is a perspective view of the head of a modified formof the razor.
Fig.7 is a jcross section taken on the line, 77 of Fig. 6.
Fig. 8 is a plan view of a blade that is used in the modified form of the razor.
Referring by; numerals to the accompanying drawings, and particularly to the con-v struction illustrated in Figs. 1 to 5, inclusive, 10 designates the top plateof the head or blade holding, frame, which plate is curved lengthwise and depending from the ends of said curved plate areshort lugs 11.
Depending from the underside of the central portion of plate 10 is a threaded stud or shank'12. The lower plate 13 of the head or frame is curved lengthwise to conform to the curvature of the plate 10, said plate 13 being slightly greater in length and width than said plate 10, and the front edge of said easily and cheaply produced, and which will be very effective in performing its intended plate 13 is provided with comblike teeth 14,
the upper surfaces of which are curved or bevelled toward their forward ends.
Formed inthe ends of the plate 13 are notches 15 that are adapt to receive the lugs 11, and formed in the center of said last mentioned plate is an aperture 16 that is adaptodto receive'shank 12.
A suitable handle 17, preferably a short metal rod, having the greater portion of its surfacemilled er knurled, isprovided in its upper end with a threaded recess 18 that is adapted to receive the threaded shank 12.
The blade 19 used with this form of my improved razor is formed of very thin sheet steel or like metal having sufficient flexibility so that it will readily conform to the curvature of the plates 10 and 13, said blade being provided along one of its sides with a cutting edge 20 and in its ends with notches 21 that are adapted to coincide with notches 15 so as to receive lugs 11 when the parts of the razor are assembled for use.
Formed in the center of the blade is an aperture 22 that is adapted to receive the stud 12.
Inassembling the parts of the razor just described, a blade 19 is positioned against the underside of top plate 10 with the stud 12 projecting through aperture 22, and with the lugs 11 ocoupylng notches 21. Lower plate 13 is now positloned against the underside of blade 19 with stud 12 projecting through aperture 16 and with the lugs 11 occupying notches 15. The recessed end of the handle 17 is now screwed onto shank 12, and in so doing plates 10 and 13 are drawn together to firmly clamp the interposed blade. I
When the parts are thus assembled, lugs 11 occupy the respective pairs of notches 15 and 21, thereby firmly retaining the two plates and the blade in assembled relation,
and the razor is now ready for use.
The widths of the plates 10 and 13 and blade 19 are such that the cutting edge 20 of the blade projects slightly'beyond' the front edge of plate 10 and overlies the intermediate portions of teeth 14.
- lin the modified construction illustrated in Figs. 6, 7 and 8 the top plate 23 is provided on its rear edge with two or more depending lugs 24 that are arranged so as to occupy notches-25 that are formed in the lower plate 26 and likewise occupy corresponding notches 27 that are formed in the rear edge of a flexible blade 28. in this construction the two plates and the blade are equal in length and top plate 23 is slightly narrower in width than the interposed blade and the lower plate.
A safety razor of my improved construction is comparatively simple, may be easily and cheaply produced, is constructed so that the flexible blade is firmly clamped in the head or frame when the parts of the razor are assembled for use and the blade holding head or frame is curved lengthwise so that it may be conveniently used on curved portions of the body.
Minor changes in the size, form and construction of the various parts of my safety razor may be made and substituted for those herein shown and described without departing from the spirit of the invention, the scope of which is set forth in the appended claim.
I claim as my invention:
In a safety razor, a backing plate curved lengthwise and having'parallel front and rear edges, the front edge of said plate being notched to provide a series of teeth, the
assess? central portion of the plate being provided with an aperture, a flexible blade adapted to overlie said backing plate and having; its cutting edge positioned above and slightly to the rear of the forward ends of the teeth on the backing plate, said blade havin an aperture that is adapted to coincide with the aperture in said plate, a top plate adapted to overlie said blade with its front edge positioned slightly to the rear of the cutting edge of the blade, a threaded shank projecting from the underside of said top plate through the coinciding apertures in the blade and hacking plate, a handle having a threaded recess that receives said threaded shank, the rear edges of said back plate and flexible blade coinciding with each other and being provided with coinciding notches, lugs depending from the rear edge of the top plate. which lugs are adapted to occupy the coinciding notches in said backing plate and blade, and the outer faces of which lugs lie flush with the outer coinciding edges of the back plate and flexible blade.
In testimony whereof I have signed my name to this specification.
MARGARET J. SMITH.
