Description

v May 25, 1943.
E. L. DES JARDINS SAFETY RAB 3B Filed Sept. 25, 1859 I [fizzy/20X Ja e 5'77:
- arator of my invention;
Patented May 25, 1943 UNITED VSTATE S- PATENT OFFICE 6 Claims.
My invention relates particularly to safety razors of the double edged type, although not limited to this use alone.
The primary object of the invention resides in the provision of a novel .and efllcient safety razor provided with a plurality of-blades acting simultaneously in series whereby a close shave is quickly effected with relatively low blade pressure against the skin and without skin irritation or damage or tendency toward inducingingrown hair, the invention contemplating the adaptation thereof to existing razors. 7
With this object in view, my invention consists in certain features of novelty in the construction, combination and arrangement of parts by which the said object and certain other, objects, hereinafter appearing, are effected all 'as fully described with reference to the accompanying drawing, and more particularly pointed out in the appended claims.
In the said drawing- 1 Figure l is a partially assembled view in side elevation of a safety razor embodying my invention with the handle thereof broken away;
Figure 2 is a similar view with the razor fully assembled;
Figure 3 is a face view of the cap member of the razor;
Figures d and 6 are face views of the razor blades of my invention;
Figure is a face .view of the razor blade sepand Figure Tie a face view of the guard member of the razor.
Referring to the drawing, I designates a conventional elongated safety razor cap member which is curved transversely and is provided with a central screw stud 2. and registering-studs 3, these studs being arranged in alinement and intermediately and'spaced longitudinally of the longitudinal edges ofthe cap member, all as is usual. See Figures 1, 2 and 3.
An elongated transversely curved guard member 4 is provided with a registering and securing slot 5 therethrough, arranged intermediately and extending longitudinally of the longitudinal edges thereof, the slot being provided with spaced en'- largements i for registering and securing engagement with the studs 2 and 3 of the cap member in the assembly of the razor, as is usual. See Figures 1, ,2 and '7. A bored handle 1 is screwthreaded on the screw stud 2 for securing the razor in assembly, as is usual.
In the assemblyof the razor, a plurality of razor blades are employed with separating means guard member 4, due to the handle therebetween which-are clamped and registered between the cap and guard members after the manner in which the conventional blade is clamped between the guard and clamp members.
vThe razor blade of my invention, as shown, is generally similar to the usual flexible double edged blades and is designated at 8. See Figures 1, 2, 4 and 6. This blade is elongated, is provided with cutting edges 9 at both longitudinal edges thereof, and is provided with a registering and securing slot ll therethrough, arranged intermediately and longitudinal edges thereof, the slot being provided with spaced enlargements I2 for registering and securing engagement with the studs 2 and 3 of the cap member in the assembly of the razor, as is usual.
The razor blade separator of my invention, as shown and designated at I3, is elongated and may be of any suitable flexible material, ormay be of rigid material properly curved transversely, as designated in dash lines at I! in Figure '1, and is provided with a registering and securing slot I5 therethrough, arranged .intermediately and extending longitudinally of the longitudinal edges thereof, this slot being provided with spaced enlargements l6 forregist'ering and securing engagement with the-studs 2 and 3 of the cap member in the assembly of the razor as is the .case
with the blades, these engagements being. in-
volved as the securing and registering means of the assembled razor. See Figures 1, 2 and'5.
In the assembly of the razor, see Figures 1 and 2, the blades I with the separator l 3 therebetween are clamped between the cap member I and the 1 being screwthreaded on the screw stud 2. The screw stud 2 and the studs 3, engaging through the slot enlargements 6 of the guard member 4; the slot enlargements 12 of the blades l-and the slot enlargements it of the separator If, in cooperation with the handle 1 screwthreaded on the screw stud 2, secure the cap member, guard member, blades and separator in. registered assembly, as shown in Figure 2.
scavenging is accomplished in the following manner The guard member 4 is provided with scavenge opening portions arranged between both longitudinal edges and the intermediate securing and registering slot 5 thereof and extending longitudinally of the longitudinal edges thereof and comprising apertures I1 therethrough adjacent the longitudinal edges thereof and spaced therealong. See Figure 7.
' The upper razor blade 8 is, and for the purextending longitudinally of the pose of interchange and quantity production all of the razor'blades are identical and are provided with scavenge opening portions arranged between both longitudinal or cuttingedges 9 and the intermediate securing and registering slot H thereof and extending longitudinally of and adjacent the cutting edges and comprising apertureg l8 therethrough adjacent the cutting edges and spaced therealonga See Figurese and 6.
The separator. I3 is provided with scavenge opening portions arranged between both longi-- tudinal edges and the 1 registering slot i5 thereof and extending longicomprising slots l9 spaced along the longitudifrom. See Figure 5, When the razor is assembled as shown in Figure 2, the scavenge openings of th blades, separator and guard "member communicate with each otherso that all of the blades are cleared of wasteremoved from the skin during the shaving operation.
In the use ofthe razor, the leading blade,
Qguardedby the guard member 4, makes a first or rough cut, after which the trailing blade makes a second or finishing cut,the skin being guarded during both cuts. As a res it, a close shave is effected without necessitating re-shaving, with resultant efficiency and less irritation to the skin, provision being made for the proper scavenging of all ofthe blades.
VWhile'I have thus described myinvention, I
do not wish to be limited to the precise detailsdescribed, as changes may be made readily with- ,out departing from :the spirit of my invention, 1 buthaving thus described my invention, I claim as new and desire to secure by. Letters Patent thfollowing:
