April 16, 1949, which matured as Patent No. 2,556,208 granted June 12, 1951, I have disclosed a unique type of razor or shaver which is charthread connection between the collar and acterized by having afrusto-conical shaver blade block l6. Similarly, the lower portion of the with a circular opening that is sharpened to problock "3 is externally knurled at 24 to enable the vide a cutting edge. The blade was shown in conblock It to be firmly held while screwing the junction with a motorized shaver, although obclamp in place. viouslyit could be used with a manually manipu- A guard pillar 25 is mounted within the cavity lated shaving head. The disclosure of my earlier l1, and includes a head 26 which projects upapplication is incorporated herein by reference to wardly into the opening l3 and terminates apthe extent that it is not inconsistent with the proximately at the plane oi? the cutting edge I I. present disclosure. The shank 21 on the pillar is offset at 28 to pro-* Referring now to Fig. 3, it will be seen that the vide a shoulder which rests on the floor of the cutting blade I0 is made from a single piece of cavity 11, and the reduced portion 29 of the shank metal, preferably cold rolled razor blade steel, extends downwardly through an opening 30 in and is formed into a frusto-conical shape by the block where it is secured in place byaknurled stamping or some other suitable means. The screw 3| which extends into a threaded recess blade has a downwardly extending lip H and an 32 in the shank. With this construction, it is inwardly tapered portion l2 with a central openpossible to remove the pillar 25 easily for the ing 13 providing an inner marginal wall 14 purpose of cleaning, and with the pillar 25, blade which is sharpened to provide a keen razor edge. [0, and collar 20 removed, all parts can readily Preferably this is done by grinding the edge ll be cleaned. from below as indicated at l5 and then honing The shaving head described above is used by both top and bottom sides of the edge to provide pressing the top of the head against the face and an extremely sharp cutting edge. then moving it across the face in any direction, Purely by way of illustration, the blade thickpreferably with a slightly circular motion, since ness may be on the order of .009 inch, the overthe blade cuts with equal effectiveness with any all dimension of the blade may be approximately direction of movement. The guard pillar 25 prean inch; the central opening 13 at least one-half vents the skin from entering the cavity to the exinch in diameter, and preferably on the order of tent that might permit cutting of the skin, and is particularly desirable when the shaver is moved over sharp contours of the face such as the chin. The relatively large opening for the blade not only enables the shaver to cut a correspondingly large swathe as it is moved across the face, but also permits the shaver to be used close to the nose and ears without interference from the shaver head.
, Whenthe-blade of this invention is used in a motorized shaver such as disclosed in my earlier application hereinabove identified, I have now found that a motor speed of approximately 120 a R. P. M. is more satisfactory than the higher speed referred to in the earlier application.
I claim: 7 v V p l. A shaving head assembly comprising a thintherein with the marginal wall of the opening 2 lying substantially in a plane and having a razor sharp cutting edge facing inwardly, said cutting edge being defined by inwardly converging surfaces each of which forms a substantial angle with the center line through the opening and with a plane normal to said center line, the portion of the blade adjacent to the cutting edge being frusto-conical in form.
, 5. A thin-walled cutting bladeofthe class described, characterized by having an opening 1 therein with the marginal wall of the opening lying substantially in a plane and having a razor sharp cutting edge facing inwardly, said cutting walled cutting blade having an opening therein ground and honed to provide an internal inwardly lar telescoped over the annular wall and secured to the block to clamp the blade firmly'in place,
and a'guard pillar'm ountedjin the block cavity andpprojecting upwardly-toward the blade opening to a pas-mm approximately level with the cutting edgepfthe blade. 1 v
7 1 4. A'thin g-walled cutting blade of the class dr s ci bdfloharacterizeduby, having an opening edge being defined by inwardly converging surfaces each of which forms a substantial angle with the center line through the opening and with a plane normal to said center line, the por tion of the blade adjacent to the cutting edge being frusto-conical in form, and the mean angle of said surfaces with respect to said normal plane being more than about 15.\
6, A thin-walled cutting'blade of the class-described, characterized by having an opening therein with the marginalwall 'of the opening lying substantially in a plane and having a razor sharp cutting edge facing inwardly, said cutting edge being defined by inwardly converging surfaces eachof which forms a substantial angle with the center line through the opening and with a plane normal to said center line, and said cutting edge being ground and honedto extreme sharpness whereby the blade is capable of shav- 1 ing action when moved in a direction transverse to said center line. i V
