SAFETY RAZOR Filed Nov. '7, 1947 INVENTOR Patented May 27, 1952 UNITED STATES PATENT OFFICE SAFETY RAZOR Armando Julio Bianchi, Buenos Aires, Argentina Application November 7, 1949, Serial No. 784,712 In Argentina December 23, 1946 1 Claim. 1

This invention relates to safety razors, and particularly to a safety razor of the removable blade type which is capable of being used in the same manner as an ordinary razor, with all the advantages aiforded by this latter type as regards comfort and effioiency but without the risk inherent in their extended use.

The razor of this invention provides an opti mum shaving operation due to the constant position of the blade relative to the beard and to the easy manner in which it is handled.

The use of the razor is carried out by a most simple movement of the hand. The entire shaving operation can be carried out in thi single position of the hand.

Finger movements which are basic and necessary in handling ordinary razors and also to a certain extent in safety razors, are unnecessary and entirely eliminated in using the improved safety razors of this invention.

The different lines and planes of the face may be covered by the improved razor in short, flexible movements of the hand derived from the wrist in a pivot-like manner.

In order to cover any zone against the hair, it is only necessary to amplify these movements through smooth displacements of the arm.

The curvature of the handle, at an angle with the blade, ensures a permanent inclined position of the blade relative to the base of the hair. This inclined position is obtained in the known razors by means of the above mentioned finger movements which require a great real of attention.

The reversal of the blade-holding head in the present razor, ensures an accurate shaving operation with a minimum change in the position of the hand.

In order that the invention may be more clearly understood, it is shown by way of example in the accompanying drawings, wherein:

Fig. 1 shows the new safety razor with the head and the handle in the same plane;

Fig. 2 shows the razor head in turning position.

Fig. 3 is a view showing the lower portion of the blade-holding head; and

Fig. 4 is an exploded view of the razor head.

In the drawings, I indicates the blade-holding head, 2 is the safety razor handle, 3 indicates a pin for supporting spring 6 and which pin also serves as a pivot for the blade-holding head. The pivot post 3 is slidably mounted in the handle 2 and fixed to the head. The rear end of the spring 6 is joined to the pivot post by any suitable means and as shown in the drawings by a collar 8 fixed to 2 the post. This arrangement retains the post in the handle while allowing the head of the razor to be moved outwardly from contact with the handle for freeing the projections and recesses on the handle and blade holder to permit rotation of the blade holder and pivot in the handle. 4 indicates a curved plate which, together with part 5, holds the razor blade. This piece 5 has attached thereto a knob l. The spring 6 is for urging the handle into contact with the blade-holding head and which, upon being compressed, enables the displacement of said head and the reversal thereof on said pin 3'. The knob is for regulating the pressure on the blade through screw-threaded connection with a screw threaded stem on piece 4.

The blade is held between members 4 and 5 and the pressure thereof regulated by means of knob 1, so that the razor is ready for use.

When gripped by the handle, the razor will only require movements in order to shave. Due to the angle of the blade relative to the handle 2, said movements will be inclined, thereby insuring an accurate cutting of the hair, without any pulling. These movements are similar to those of a scythe in cutting grass, or of a sickle in cutting wheat.

When it is desired to reverse the position of head I so as to facilitate shaving against the hair, for example, without changing the position of the handle 2 with respect to the hand gripping the razor handle, the head I is pulled away from the handle until it can clear the projections, shown in dotted lines in Fig. l. The head I is then rotated with the pivot post 3 through whereby the face of head I carrying the knob 1 will remain as the rear face but in the same plane as the handle. Upon releasing the head I, the spring 6 will force the head against the handle and it will be locked in this position due to the abutment of the projections against the head zones. This means that the head I can be turned and locked in one of two positions in which the head will remain in the same plane as the handle, said positions being 180 from each other.

It is evident that many changes and modifications may be made in the details of the construction as disclosed herein by way of example, without departing from the scope of the invention as set forth in the appended claim.

I claim:

A safety razor of the removable blade type comprising a handle, said handle having a first and a second portion, said first portion constituting a gripping member and said second portion constituting a supporting member having a bladeholding head, said first and second portions of 3 said handle being offset at an obtuse angle, a REFERENCES CITED Plvot post Shdably mounted 111 Send Second The following references are of record in the tion, ablade-holding head fixed to the free end of fi f said pivot post and supported thereby, spring 16 o t 15 patent means surrounding said pivot post and normally 5 forcing said head against said handle, means in UNITED STATES PATENTS said pivot post for causing the compression of Number Name Date said spring upon forcing said head away from 576,862 Lebold Feb. 9, 1897 said handle through sliding of said pivot pin outwardly of said handle, said head being rotatable 1Q EI N PATENTS along with said pivot post when so forced away Number Country Date from said handle so as to assume a selected one 47350 Denmark Oct 9, 1933 of two shaving positions at 180 from each other 619,429 Germany Oct 9' 1932 and in the same plane as said handle.
