SAFETY RAZOR Filed Aug. 18, 1942 INVENTOR. Jc zn S n art, BY I Patented Apr. 25, 1944 SAFETY RAZOR Jan de Swart, Los Angeles,

Calif., assignor of one- Beverly Hills, Calif.

Application August 18, 1942, Serial No. 455,160 4 Claims. (01. 30-741) My invention has to do with safety razors.

It is among the principal objects of my invention to provide a safety razor which embodies a novel, simple and effective means for locking the parts together; which is extremely sanitary; which is of light weight; and which embodies the improved blade holding means.

Still further advantages are inherent in my invention and how those as well as the foregoing named objects are achieved will be best understood from the following detailed description of a presently preferred embodiment, for which purposes I shall refer to the accompanying drawing, in which:

Fig. 1 is a side elevation;

Fig. 2 is an end elevation;

Fig. 3 is a top plan view;

Fig. 4 is a bottom plan view;

Fig, 5 is a section on line 5-5 of Fig. 3; and

Fig. 6 is a perspective showing the parts disassembled.

Referring now to the drawing, I show at 5 a handle, at 6 a blade receiving base formed integral with the handle and at I a blade retaining plate, a blade being denoted by the numeral 8. Elements 5, 6 and l are preferably molded of a suitable plastic although of course other materials may be used.

The top surface of base 6 is arched or convexed. as shown at Ill, and presents a medial longitudinal rib [2 which, when the device is assembled, projects through a longitudinal medial slot 14 provided in blade 8 as well as a registering longitudinal slot I! provided in the retaining plate.

The retaining plate 1 has an undersurface I5 concaved to conform to the shape of base surface ill. The respective ends I8 of the retaining plate extend outwardly beyond the ends of the base 6, as best shown in Fig. 1, and have down-- wardly and inwardly disposed flexible cars 20 at each corner which project under and engage the undersurface of the base 6 when the device is assembled.

In assembling the device, the blade 8 is placed on the base surface it] with the rib l2 projecting through the blade slot l4 and then the retaining plate 1 is placed over the blade with its concaved surface towards the blade, rib l2 extending into slots ll. By pressing the plate 1 downwardly towards the base, the corner ears 20 snap over the ends of the base into the position shown in Fig. 1. Thus the blade is clamped between the cooperating surfaces lil, I5 of the base and retaining plate and is flexed into and held in the curved position best shown in Figs. 2 and 5. In this position the blade is firmly held with its edge portions 8a disposed over the serrated side edge portions 6a of the base and exposed slightly beyond the side edge portions la of the retaining plate. While the blade is held in curved cross section it is not so distorted as to tend to break. This is an advantageous feature inasmuch as razor blades are relatively thin and brittle.

To disassemble the razor it is only necessary to press the thumb against either of the corner ears 20, urging the ear outwardly and upwardly until it is flexed sufficiently to escape over the end of the base.

My device is composed of a minimum of parts and is easily cleaned because there is an entire absence of threaded and pivoted parts, which such parts are difficult to reach for cleaning purposes;

While, in the foregoing description, I have resorted to various details of structure and association of parts, I wish it understood that I do not thereby confine my invention to such specific details. Rather, various modifications and adaptations may be made within the broader scope of the invention as defined by the appended claims.

I claim:

1. A safety razor comprising a base, a handle secured to and disposed at an angle to the base, a blade retaining plate on the base, said plate having resilient flexible end portions engaging over the ends of the base whereby to clamp a blade between the plate and base.

2. A safety razor comprising a base, a handle secured to and disposed at an angle to the base, a blade retaining plate on the base, said plate having resilient flexible corner portions engaging over the ends of the base whereby to clamp a blade between the plate and base.

3. A safety razor comprising a base having an arched top surface, a retaining plate mounted on the base and having an inner surface conforming to the top surface of the base, a flexible blade disposed between the said base and plate, a longitudinal slot in the blade, a longitudinal slot in the plate registering with the slot in the blade, a longitudinal rib projecting outwardly from the top surface of the base through said slots and resilient ears on the corners of the plate, said ears engaging the undersurface of the base whereby to hold the plate in position on the base.

4. A safety razor of the class described comprising, in combination, a base, a blade-clamping plate superimposed on the base and means for securing the plate on the base including depending undercut resilient corner ears on the plate having clamping engagement with the corner portions of the base.

JAN DE SWART.
