1 Claim. (Cl. 30--72) This invention relates to razors of the type designed to hold double-edged razor blades.

The object of the invention is to provide such a razor that can be charged from a dispenser, that will enable the user to cleanse the assembly by washing without risk of the blade becoming dislodged from the razor, that will prevent the user using the second edge of the blade by accident, and that will enable the user to bring the second edge into use when he desired without removing the blade from the razor.

Accordingly the present invention provides a razor having a hollow handle with one end thereof open, a symmetrical elongated platform having a central opening coinciding with the opening in said handle at said open end, said platform having medially positioned openings on opposite sides of said central opening, said hollow handle having .a spring fastening secured therein, an unsymmetrical cover cooperating with said platform for securing a double-edged blade therebetween, said cover having a central stem and two medial pins extending outwardly from the bottom side thereof and received in said central and medial openings, respectively, of said platform, said central stem having a head thereon which is clampingly received by said spring fastening in said handle, for securing the cover in operative position, said unsymmetrical cover having an operative shaving side and a blade cutting-edge protecting side whereby when one edge of the blade becomes dull said cover can be rotated to use the second razor blade edge and wherein one edge of the double-edge blade is protected at all times, said hollow handle having a threaded shaft rotatably mounted therein, threads in said central stern mating with the threads on said threaded shaft, means for rotating said shaft to draw said cover towards said platform and into operative position.

The invention also provides means whereby the angle of exposure of the blade in the holder referred to above can be adjusted.

These and other features of the invention will now be described with reference to the accompanying drawings of which FIGURE 1 is a sectional view of the razor according to the invention, FIGURE 2 is a front view of the cover, FIGURE 3 is a plan view of the platform and handle, FIGURE 4 is an end view of the cover, FIG- URE 5 illustrates one means of adjusting the angle of the blade and FIGURE 6 is a sectional view of the cover.

The razor blade holder consists of a handle 11, a platform 12 and a cover 13, the blade 14 being placed between the cover and the platform. The cover 13 is unsymmetrical about the centre line of the platform 12, its front part 19 being of the correct length to expose the edge of the blade 14 when the razor is assembled, and the back part 20 is wide enough to cover the other edge of the blade to prevent it being used. The cover can have side plates 21 to enable the cover to be grasped easily when necessary. The cover also has positioning pins 18 which enter holes 22 in the platform 12 to locate the cover and a central stem 15 which terminates in a head 17 and is internally threaded as at 16. The cover also has recesses on either side to accommodate the stud 23 referred to later.

The platform 12, has in addition to holes 22 for positioning pins 18, a stud 23 which is undercut as shown Patented June 13, 1967 at 33, a central hole 24 through which the handle is connected, ridges 31 for locating the blade and a number of slots 32 for the escape of lather.

The handle 11 is connected to the platform 12 by having its end passed through the hole 24 in the platform and spun over as shown at 25. The handle is in two parts, the lower part 34 carrying at its upper end a threaded shaft 26 which engages the thread 16 in the central stem 15. The handle carries a C spring 27 in the recess 35 which can engage and hold the head 17 on the central stem 15. The lower part 34 of the handle can be rotated relative to the guard platform 12. If desired, the relative positions of the handle and platform can be made adjustable by threading the outer surface of the upper end of the handle and fitting an internally threaded sleeve 28 over this threaded portion. This enables the platform 12 to be raised and lowered slightly relative to the handle and if the relative positions of the cover and handle are fixed, for example by arranging that the thread 16 terminates at the correct place, the sleeve 28 can be used to adjust the shaving angle of the blade. A pointer 29 can be provided on the handle 11 and a scale 30 on the sleeve 28 to enable the user to check the shaving position.

The two parts of the handle are retained by a spring 36 which engages slot 37 in the upper part of the handle and a slot 38 in the lower part 34 of the handle. The lower part of the handle has a neck portion 39 which fits into a socket 40 in the upper part of the handle.

In use the blade is discharged from the dispenser over the stud 23 and slid along until the blade is held by the undercuts 33 and is correctly positioned by the ridges 31 fitting the slots in the blade. The cover 13 is applied to the top of the handle and the central stem 15 is pressed into the open end of the handle until the head 17 is gripped by the spring 27. The lower part 34 of the handle is now turned and the threads 16 and 26 engage to lower the cover into position for shaving. One edge of the blade is exposed from the end 19 of the cover 13 but the other edge is covered by the end 20. When shaving is completed, the lower part of the handle is unscrewed so that the cover is lifted from the blade but is retained on the handle by the head 17 on the central stem 15 and the spring 27. The razor can now be washed, for example by being placed in running water, and when it is clean threaded shaft 26 carried by the lower part 34 of the handle is screwed back into the central stem and the razor is ready for further use.

When the first edge has been used as much as possible, the razor is unscrewed into the washing position and the cover is then pulled off. The blade is still held on the platform by the stud 23 and the ridges 31. The cover is turned round and re-applied to the razor, but now the end 19 would uncover the second edge of the blade and the used edge would be covered by the end 20.

The undercuts 33 should be deep enough to allow the blade to be flexed into its correct shaving position when the cover is screwed into the working position.

If adjustment of the shaving angle is required, the sleeve 28 is provided and this is turned until the required adjustment is obtained. The position of the pointer indicates the degree of adjustment so that the user can set the razor as desired.

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

In a razor having a hollow handle with one end thereof open, a symmetrical elongated platform having a central opening coinciding with the opening in said handle at said open end, said platform having medially positioned openings on opposite sides of said central opening, said hollow handle having a spring fastening secured therein, an unsymmetrical cover cooperating with said platform for securing the double-edged blade therebetween, said cover having a central stern and two medial pins extending outwardly from the bottom side thereof and received in said central and medial openings respectively, of said platform, said central stern having a head thereon which is clampingly received by said spring fastening in said handle, for securing the cover in operative position, said unsymmetrical cover having an operative shaving side and a blade cutting-edge projecting side where-- by when one edge of the blade becomes dull said cover can be rotated to use the second razor blade edge and 10 threaded shaft rotatable therewith, threads in said central stem mating with threads on the threaded shaft, means for rotating said shaft to draw said cover towards said platform and into operative position.
