SAFETY-RAZOR.

Specification of Letters Patent.

Applicationy ledillarch 18, 1920. Serial No. 366,918.

To all wlan/Lit may concerm. Be it known that I, ISAAC N. WEBER, a

outer surface of which is flush with the outer surface of the handle which produces citizen of theA United States, and resident of`\a finished and ornamental appearance at the city of New York, borough of Manhattan, in the county and State of New York,

have invented an Improvement in Safety- Razors, of which the following is a speclication.

This invention relates to shaving instruments, particularly to safety razors adapted provement upon the safety razor described and claimed 1n Letters Patent of the United States granted to me November-6th, 1917, number 1,245,646.

' The object of the invention 4is to simplify the construction shown in my said prior patent by dispensing with some of the parts, thus economizing in cost of manufacture, and at the same time rendering the device more convenient in handling, and better adapted for use.

The details of the invention are herein,

after particularly described.

In the accompanying drawing A Figure 1, is a plan view partly in sec` tion showing my improved razor with the parts assembled for carrying in the pocket.`

Fig. 2, is a plan View of the same in an operative position. l

Fig. 3, is a plan view of the guard and blade clamping arm, the latter being in an opened position.

Fig. 4, is a vertical section of the same.

Fig. 5, is a section on the broken line 5 5 of Fig. 1.

Fig. 6 isa plan of` one of the razor blades, and

Fig. 7 is an end view of the same.

For clearness of illustration all the ligures show the parts of the device in enlarged size.

Similar reference characters indicate like parts throughout the several views.

Referring to the drawing, 10, indicates a hollow handlemade of sheet metal or of any other suitable material. This hollow handle is substantially elliptical in cross section. A blade-holder 11, is fixed inside the handle at one end thereof, and extends therefrom a predetermined distance,. that portion extending beyond the end ofthe handle being adapted to receive a cap 12, the

this end of the handle. u The other end of the handle is open, and 1s adapted to receive and hold the razor guard 13, either in its operative or inopera tive position.

lThe guard 13, is substantially flat, and is provided with an integral shank 14, the greater portion of which is .of thickened material and of a size and shape to fit into the open end 15, of the hollow handle 10; there being a transverse rib 16, upon the shank which limits the extent to which the shank may be inserted into the handle either when the guard is in position for use, or

upper part.

The other end of the guard is provided with two spaced lugs 18, provided with alined pivot pin holes.

19, denotestwo short vertical lugs spaced apart a predetermined distance'upon the upper side of the guard 13, between which the razor blade 20, is inserted, there being a notch 21, in each end of the blade into which said lugs fit, so that the blade lies flat upon the' guard, and its movement either longitudinally or laterally upon the guard is impossible. i

22, indicates a blade clamp which consists of an'arm flat on its under surface and of the same length as the guard 13 and its shank 14, and of a width adapted to allow its free end to fit into the groove 17, in the guard shank 14, there being a transverse rib 23, on the upper surface of said clamp at this end which registers with the rib 16, on the shank, when the clamp is closed forming a continuation of said rib all around, the clamp being shaped to fill the groove in the shank while its upper surface matches with the surface of the shank.` y

The other end of this clamping arm 22, is provided with a downwardly rounding lug 24, provided with a transverse hole, which Patented NOV. 9, 1920.

l lug fits between the spaced lugs 18, on the end of the guard, and is pivotally connected in such position by a pivot pin 25.

There are two spaced recesses 26, in the underside of the clamp 22. i

When the razor is to be used for shaving, the guard is withdrawn from the handle by gras ing the pro'ecting end of the shank 14, etween the t umb and forenger; the blade clamp 22, is then swung upwardly on its pivot pin 25, and one of the lat blades 20, laid upon the top surface of the guard 13, the lugs 19, on the guard entering and projecting slightly above the `notches 21, in the blade; the clamp 22, is then closed, the top of the lugs 19, entering the recesses 26, on its underside, while the free end of' the clamp enters the groove 17, in the shank 14, of the guard. This end of the clamp having a tendency to spring upward, it is pressed downwardly by the thumb and fingers, while it., with the shank 14, is being inserted into the open end 15, of the handle 10, and this tendency to spring outwardly acts to se* .curely retain the shank end of the guard within the hollow handle either while the guard is in an operative position, or within the handle. i

It will be seen that the blade 20, 1s so securely clamped in position for use that there is no possibility of its movement in any direction, thereby rendering the razor absolutely safe for shaving purposes, while its manipulation is exceedingly simple and convenient.

When the parts are assembled for carrying in the pocket, as illustrated in Fig. 1, the device is no thicker and but little broader than a` Jfountain pen or pencil, and can be carried in the vest pocket in a similar manner. The outer surface of the handle may be engraved or' ornamented in any desired manner.

I'claim as my invention 1. A safety-razor, comprising a hollow handle, a guard havin at one end a shank provided with a longitudinal groove, said shank fitting within the open end of the handle and'provided with a stop intermediate its. length abutting against the end of the handle to limit the insertion shank therein, a blade clamping arm pivotally connected at one end to the opposite end of the guard, its free end entering said groove in the shank when the arm is swung .parallel with the guard, and a blade clamped between said guard and arm. l

2. A safety-razor, comprising a hollow handle, a guard having at one enda a shank provided with a longitudinal groove and adapted to iit within the open end of said handle, a stop upon said shank intermediate its length abutting against the end of the handle to limit the insertion of the shank ISAAC N. WEBER.
