J. L. KING SAFETYV RAZOR Original Filed Oct. 5. 1950 N mi wir mi@ INVENTOR ATTORNEY Patented Dec." 13, 1932 UNITED STATES- JOHN L. KING, OF NEW YORK, N. Y., ASSIGNOR TO THE KING- HOLDINGS, INC., A CRPO- li'rl-:N'rl OFFICE RATION F RHODE ISLAND SAFETY RAZOR Application-filed lOctober 3, 1930, Serial No. 486,265. Renewed April 12, 1932.

This invention relates to safety razors, and more particularly to a safety razor of the type ,wherein the blade is reciprocated longituciprocating device in such a razor, wherein the number of actuating elements is reduced to a minimum, thus greatly simplifying the action ofthe razor and reducing the cost of manufacture.

These and other objects are attained by the novelconstruction,combination and arrangement of partsv hereinafter described and shown in the accompanying drawing, constituting a material part of this disclosure and in which: y

.Figure is a plan view of the safety razor.

Figure 2 is an elevational view ofthe razor.

Figure 3 is a side elevational view of the razor. f

Figure 4 is a plan view of the razor with the retaining plate extended. y

Figuref is a sectional view taken on line 5--5 of Figure 1.

Figure 6 is a plan view of a blade used in the razor.

Figure 7 is a plan view of a support for the blade shown in Figure 6.

Referringto the drawing, the safety razor is shown to include` a handle 6, preferably tubular, having its upper extremity 7 passing through an aperture ina blade supporting plate 8, theyportion 7 being crimped over the edges of the aperture in the plate to .securely hold the handle thereto. i

The plate 8 is provided with

downturned guards

9 and 10, so that the razor is adapted for use with a double edged blade. The plate 8 also has apertures 11 through which excess lather and Water, etc.,fmay drain so that the action of the blade will not be impeded. ,Projecting upwardly from the plate 8 are a pair of lugs 12 for positioning a blade on the plate, the latter also having a notch 13 at one end which cooperates with a spring clip 14 integral with a retaining plate 15, which has a downturned portion 16 at the opposite end hinged .by means of a pivot pin 17 to down turned portions "18 of the plate 8.

The retaining plate has a longitudinal slot, at the ends of which are struck up from the plate a pair of

ears

19 and 20, in which are pivotally mounted the

projections

21 and 22, respectively, which projections are integral with a roller 23, having knurled p0rtions 24, and a centrally located cam slot 25.

Positioned below the cam slot is a saddle 26 having lips 27 slidably mounted on the longitudinal edges of the aperture in the retaining plate 15. Fixed to the saddle 26' is a pin 28 adapted to be acted upon by the cam slot 25, said pin 28 having a head 29 passing through a central aperture in a razor blade 30, the latter having elongated slots 31 at its ends through which pass the lugs 12 of plate 8.

I In operation, the blade is positioned on the plate 8 by passingthe lugs 12 through the slots 31, and the retaining plate 15 is snapped into position over the supporting plate 8, bringing thehead 29 into position in the central aperture of the blade 30. The razor is now in condition for the shaving operation, which is similar to the usual method employed with a double edged blade. As the blade is drawn over the face in a shaving position, the knurled portions 24 contacting with the surface being shaved, cause the roller 23 to rotate and the cam slot 25 and pin 28 to reciprocate the blade 30.

In Figure 6 is shown a preferred form of blade for use in the razor. rlfhis blade is provided with a Apair of slots 40 at each end,

each pair of slots extending angularly from a point near the transverse axis an'd edges ofthe blades to points near the ends and longitudinal axis of the blades, The supporting plate 8 (see Figure 7) has four upstanding angularly directed bars 41 which cooperate with the slots 40 to guide the blade durto receive the head 29.

It will be seen thatthe blade, in addition to the usual cutting action, has a transverse cutting action, which insures a positive cutting of the hairs. This feature isespecially desirable for tough beards in which the Vusual blade has a tendency to slide over the hairs. With the razor herein disclosed, the transverse cutting action prevents the sliding of vthe blade over the hairs, and insures a smooth and satisfactory shave.

The foregoing disclosure is to be regarded as descriptive and illustrative only, and not as restrictive or limitative of the invention, of which obviously an embodiment may. be constructed including modifications Without departing from the general scope herein indicated and denoted in the appended claims.

Having thus described my invention, what I claim as new and desire to secu e by Letters Patent, is:

1. In a safety razor, a handle, a razor blade support att-ached to the handle, a plate for retaining the blade on the support, -a saddle slidably mounted on said plate, a pin projecting from the saddle,and cam means lrotatably mounted on the plate for cooperating with the pin to reciprocate the saddle.

2. In a safety razor, a handle, a razor blade support fixed to the handle, lugs projecting upwardly from said support to position a razor blade thereon, a plate for retaining the blade on the support, a saddle slidably mounted on the plate, a pin fixed to the saddle, said pin having a head adapted to pass through a central aperture in ablade carried by the support, and cam means carried by the plate for cooperating with the pin to reciprocate thesaddle.

3. In la safety razor, a tubular handle, a razor blade su port attached to the handle, said! support above the tubular handle, a plate for retaining a blade on the support, a. saddle slidably mounted on the plate, a pin fixed to the saddle, said pin having a head passing through the aperture in the, support, and cam means carried by the plate for cooperating with the pin to reciprocate the saddle.

4. In a jsafety razor, a handle, a razor blade support attached tathe handle, means on the support for positioning a razor blade thereon, a plate for retaining a blade on the support, a pinslidably mounted on the plate, and cam means carried by the plate and cooperating with the pin to reciprocate the latter.

5. In a safety razor, a handle, a razor'blade support attached to the handle, a plate fox' retaining a blade on the support, a pin slidably mounted on the plate, and cam means carried by the plate and cooperating with the pin to reciprocate the latter.

6. In a safety razor, a handle, a razor blade support attached to the handle, a plate for retaining a blade on the support, a pin slidably mounted on the plate, and a roller carried by the plate, said roller having a cam slot cooperating with the pin to reciprocate the latter.

7. In a safety razor, a handle, a razor blade support fixed to the handle, means on the support to posit-ion a razor blade, a plate for retaining a blade on Ithe support, a saddle slidably mounted on the plate, a pin fixed to the saddle, said pin having a head adapted to pass through a central aperture in a blade carried -by the support, and means carried by the plate for cooperating With the pin to reciprocate the saddle.

8. In a safety razor, a handle, a razor blade support attached to the handle, a razor blade having` a central aperture, means to position the blade on the support, a plate for retaining the blade on the support, a saddle slidably mount-ed on the plate, a pin fixed to-the saddle and having a head passing through the aperture in the blade, and means carried by the plate cooperating with the pin to reciprocate the saddle. j

9. In a safety razor, a handle, a razor blade support attached to the handle, a razor blade having a pair of slots, a plate for retaining the blade on the support, a pin slidably mount-ed on the plate, said pin engaging the razor blade, cam means carried by the plate and cooperating with the pin to reciprocate the blade, and a pair of projections on the support cooperating with the slots to guide the blade.

In testimony whereof I aflix lnysignature.
