RAZOR Filed Feb. 2, 1938 INVENTOR Twig lmfzm/m Patented Jan. 10, 1939 UNITED. STATES PATENT OFFICE 1 Claim.

This invention relates to safety razors and more particularly to razors of the flexible blade type.

An object of the invention is to provide a novel and improved razor of the above type in which the blade may be readily inserted or removed.

Another object is to provide a novel and improved construction in a safety razor whereby the blade may be inserted or removed without unscrewing the handle.

Another object is to provide a razor having a novel and improved construction which permits the handle to be readily snapped into or out of operating position.

Various other objects and advantages will be apparent as the nature of the invention is more fully disclosed.

Although the novel features which are believed to be characteristic of this invention will be more particularly pointed out in the claim appended hereto, the invention itself may be better understood by referring to the following description, taken in connection; with the accompanying drawing, in which a specific embodiment thereof has been set forth for purposes of illustration.

In the drawing:

Fig. 1 is a. side elevation of a razor embodying the present invention;

Fig. 2 is a section taken on the line Fig. 1;

Fig. 3 is a transverse section taken on the line 3--3 of Fig. 2 and looking in the direction of the arrow;

Fig. 4 is a similar transverse section taken on the line 4--4 of Fig. 2; and

Fig. 5 is an exploded view showing the parts of the razor in position to be assembled.

In the following description and in the claim certain specific terms are used for convenience in referring to various details of the invention. It is to be understood, however, that these terms are to be given as broad an interpretation as the state of the art will permit.

Referring to the drawing, the invention is shown as applied to a razor having a hollow, tubular handle I0 attached to a guard II and having a flexible blade I2 secured to the guard II by means of a removable head I3. The guard II, blade I2 and head I3 may be of standard construction and shape substantially as shown in the drawing. For that reason a detailed description thereof is not included herein.

In the embodiment shown, the head I3 is provided with a pair of pins I4 which extend through 55 a slot I5 in the blade I2 and through suitable apertures provided with notches I6 in the head II. These pins I4 are I8 which are adapted to be engaged by lingers I9 carried on pawls 2f] which are mounted within the hollow handle lo and extend outwardly through slots 2I therein. A spring 22 may be provided to normally urge the pawls 20 outwardly and to cause the fingers I9 thereof to engage the notches IB and to thereby securely hold the head I3 in assembled position. The heads of the pins I4 are rounded as at 23 and the fingers I9 are provided with slightly rounded surfaces 24 which are adapted to automatically snap over the heads of the pins I4 and into the notches I8 when the parts of the razor are assembled. The pawls 20 are provided with rounded projecting surfaces 25 which extend through the slots 2| in the handle I0 and are adapted to be engaged by the hand of the operator for retracting the pawls 20 when the razor is to be dis-assembled.

In the above mentioned construction it will be noted that the guard II is permanently attached to the handle I0. 'Ihe razor accordingly has only two separable parts. When it is desired to insert a blade the blade is positioned on the head I3 in the usual manner with the slot I5 of the blade extending over the pins I4 which hold the blade in its proper position. In order to assemble the razor the guard I I is pressed against the blade I2 with the pins I4 extending through the apertures I6 therein. This may be accomplished by grasping the handle I0 and applying longitudinal pressure for causing the pawls 20 to be retracted by the cooperating surfaces of the fingers I9 and the pins I4 until the guard has been depressed sufficiently to permit the lingers I9 to snap into the notches I8. In this position the fingers securely hold the razor in assembled position. The razor may now be used in the usual way and when it is desired to remove the blade, this may be accomplished by pressing inwardly on the surfaces 25 of the pawls 20 to thereby release the fingers I9 from the pins I4 and permit the guard II and head I3 to be separated.

It will be noted that in the above construction the razor may be assembled or dis-assembled with a single movement of the hand and without requiring the handle to be turned or screwed. Furthermore, the use of the razor is simplied'inasmuch as it involves only two separable parts. It will be noted that the construction is simple, sturdy and is so arranged that it may be manufactured from standard parts.

,Although a specific embodiment of the invention has been shown for purposes of illustration, it is to be understood that the invention is not to be limited thereto, but that various changes and modications may be made therein as will readily appear to a person skilled in the art. The invention is only to be limited in accordance with the following claim when interpreted in View 'of the prior art.

What is claimed is:

A safety razor, comprising a hollow handle having a guard member permanently attached thereto, a head adapted to cooperate with said guard member to secure a blade in position therebetween,

the blade, pawls carried in said handle and extending laterally through apertures therein, a spring carried in said handle and normally holdsaid head having pins extending' through apertures in said guard member to hold ing said pawls spread apart, said pins having notches adapte dto be engaged by said pawls for holding said parts in assembled position, said pawls and said pins having cooperating surfaces adapted and arranged to permit the pawls to snap over said pins and into said notches when the parts are completely assembled, said pawls having surfaces extending through apertures in said handle and adapted to be engaged by the fingers of the operator for retracting the pawls, the resilience of said spring being the sole means for holding the said pawls in locking position with the guard member secured against endwise movement, said spring being so constructed and arranged that the finger pressure on said surface constitutes the sole releasing motion required for dis-assembling the parts.
