935,032, Patented Sept. 28, 1909.
%. Q a v LEON K'NMTEB, OF HU'BOKEN, NEW JERSEY.
EAIETY-RAZOR.
Specification of Letters Patent. Patent-ed Sept. 28, 1909.
Application fllcd June 5, 1909. Serial No. 500,371.
To will whom it may concern:
Be it known that I, LEON KNAs/rmn, a citizen of Russia, residing at Hoboken, county of Hudson, State of New Jersey, have invented certain new and useful Improvements in Safety-Razors, of which the following is a full, clear, and exact description. I
My invention relates to safety razors.
The object is to improve and simplify the construction.
Various advantages of the device will be apparent from a reading of the following description and an examination of the accompanying drawings.
In the drawings, Figure 1 is an edge elevation. partly in section, a portion of the handle being broken away, said view being slightly enlarged. Fig. :2 is a section of the blade supporting head with the blade-locking key removed. Fig. 3 is an end elevation of the blade-locking hey detached. Fig. 4 is a plan view of Fig. 2. Fig. 5 is a front elevation, the blade-locking key being partially displaced.
1 is a handle.
2 is a head. the opposite outer surfaces of which are arranged at substantially right angles to each other so as to form a ridge. The ridge is provided with an elongated undercut groove 2 in which the blade-locking key 3 is located when the parts are assembled.
4-4 are blades supported on the outer surfaces of the head 2.
5 5 are blade guides at each end of each blade supporting surface into the embrace of which the. blades may be slid from the ridge. The lower end of each clip 5 is turned in to engage the cutting edge of the blade at each corner, serving thereby to position the cutting edge of the blade properly with respect to the guards 6-6 an also serving to prevent the user from becoming injured by the corners of the blade. Between the guards i )(l, a multitude of clearance slots are provided to permit the lather to escape as the razor is being used. The blade-loclo ing key 3 is preferably provided with flexible spring clips 33'-, which, when the key is in placees shown in Fig. 1, each rests upon its respective blade, holdm the same firmly down upon the surface 0 the blade supporting head. These clips 3 may be made integral with the blade-locking key 3, it desired, but that is immaterial.
From the foregoing it will be at; once apparent that the article'is provided with two blades always ready for use. Each of these blades is arranged at a suitable angle relatively to the handle so that shaving may be accomplishml without any special effort on the part of the user to incline the blade properly during the shaving operation. The undercut groove 2 may be of any suit able cross section but, for convenience of illustration, I have shown the same dovetailed. In Fig. 5 the key 3 is shown as partially removed to illustrate the direction of movement of the key durin the process of locking or unlocking the blades, Looking at Fig. i. it will he observed that the upper ends of the cud clips o terminate at a suitable point bclou' the ridge to afford clcarancc for the clips 3 of the locking key.
Various changes may be made without departure from the spirit or scope of this invention.
\Yhat I claim is:
1. safety razor comprising a blade sup-- porting head having oppositely extendin hladc supporting surfaces. a clip at each end of each blade supporting surface arranged to receive the adjacent end of a blade, :1 bladc-loclting key carried by said head the head being provided with means to interlock with the l i at thc rcar edges of said blades, and a plurality of guard at the opposite ilgc of each blade supporting surface.
2. saicty razor comprising a blade sup porting head having oppositely inclined blade supporting, surfaces. :1 clip at each end oi cach blade su )portin surface arranged to receive. the adyacent end of a blade, 0 blade-locking key carried by said headalr head being provided with means to interlot with the hey at the meeting an is of said blade supporting surfaces, :1 p urality of guards along the opposite edge ofpaclrblndb: r
:l. A safety razor comprising a blade iiupsupporting surface.
porting head having oppositely inclined blade su )orting surfaces, a clip at each end of said ade so porting surfaces arranged to receive the a jacent end of a blade, and means to cover and protect each corner of the blade at its cuttin edge, a blade-locking key carried by said lIEM, the head being provided with means to interlocl with the lade supporting surfaces, means carried by each surface to position a blade thereon, a longitudinally movable bladelocking key carried by the head at the meeting angle of said blade-locking surfaces.
5, A safet razor comprising a blade supporting hea having two oppositely inclined blade supporting surfaces, means carried by each surface to position a blade thereon, a longitudinally movable blade-locking key carried by the head at the meeting angle of said blade-locking surfaces, cli 5 carried by said blade locking key arrange to overstand the blades. L p
6. A safet razor comprising a blade supporting hea having two oppositely iriclined blade supporting surfaces, means carried by each surface to position a blade thereon, a longitudinally movable blade-locking key carried be the head at the meeting angle of said bla e-locking surfaces, flexlble clips carried by said blade locking key arranged to overstand the blades.
7. In a safety razor, a blade-supporting head having a blade-sup orting portion, a clip at each end of salti blade-supporting portion arran ed to receive the adjacent end of a blade, a ongitudinally movable bladelocking key, said head being provided with means to interlock with the ke at the rear of said blade to hold the latter 1n place, and
a plurality of guards along the edge of said blade-supporting portion adjacent to the cuttlnge ge of a blade when the latter is in place. a
