7 Claims. (01. 30-51) The present invention relates to safety razors clamp and guard member 12 is provided with and has for its objects the provision of a simple, trunnions ll engaged in notches I8 in the end inexpensive device in which a wafer blade may walls whereby the member I2 is tiltably and be readily inserted and as readily removed; removably engaged in the housing II. This which may be easily cleaned; which, while T- member at its forward end is provided, in the 5 shaped when in use, may be arranged with the usual manner, with a guard portion l9 and a head and handle in parallel relation for occublade clamping portion 20. The rear portion pance of a minimum of space; which may be ii of the member I2 is off-set as at 22. This quickly disassembled for thorough cleaning and rear portion is also provided with an opening 23.

The handle is Fig. 6 is a similar view showing the manner then swung to the position shown in Figures 1 of disengaging the handle from the head. and 2, the cam lug 28 engaging the under face Fig. 7 is a plan view of a preferred form of of the plate l2 at its off-set to rock the plate 45 blade. about its trunnions so the portion 20 thereof Fig. 8 is a partial vertical sectional view of clamps the blade against the under face of the an alternate form of razor head. housing top I4. The blade is now effectively In the present form of the invention the razor positioned in the razor against displacement. comprises a head portion 10 consisting of a In the above manner, the parts may be again 50 housing H, a clamp and guard member I 2, and manipulated for the removal or replacement of a handle [3 normally arranged at right angles a blade. to the head. It will be noted that the cams 21 and 28 at The housing It! is preferably formed with a all times control the movement of the plate top [4, and walls l5, and a rear wall E6. The I2, the cam 21 serving to open the head and 55 retain it open, and the cam 28 serving to close the head and retain it closed.

The detent 30 insures proper positioning of the handle during shaving and the off-set 22 in the plate l2 permits the application of considerable clamping pressure by the cam lug 28 since said plate may flex slightly under the force of this pressure.

The razor structure, as above described, permits of movement of the handle in either direction. At times it is desirable, however, to store the razor in a small space. For this purpose, therefore, one of the cam portions 3| may be omitted as shown in Figure 5 so the handle l3 may be swung in the direction of the arrow 34 without moving the clamping plate l2. In this condition, a razor containing a blade may be carried, as for instance, in a convenient coat pocket. When it is desired to remove the. blade, the handle is swung in the direction of the arrow 35 and the action is as above described.

Ordinarily, it is sufiicient to shake the razor after washing to free it of excess moisture before storing. However, at times it is necessary to thoroughly clean all the razor parts. This is best accomplished when all the parts comprising the razor are disassembled. In the present instance disassembly of the parts may readily be done by providing the pivot pin 25 with flattened portions 35 which adapts said pin. for movement along the open slot ii'l in the member 24. When the handle I3 is thus removed, the plate 52 may be removed from association with the housing H.

In the form of the invention shown in Figure 8, the head is formed as an integral member comprising the top wall H and the clamp and guard portion li resiliently associated so that normally these portions are spaced (dotted lines) for the reception of a blade when the handle l3 is positioned parallel to the head, and are in clamped relation as shown when the handle is in right angled position. This structure provides a razor of extreme simplicity and durability which is quite economical to manufacture.

While the above is descriptive of the preferred embodiments of the razor as illustrated, it is apparent that immaterial changes in design may be made by skilled persons without departing from the scope of the invention as hereinafter claimed.

What I claim as new and desire to secure by Letters Patent, is:

1. A razor comprising a head portion consisting of pivotally engaged members, and a handle for the razor, pivotally connected to one of said members, said razor handle being provided with cam means for positively rocking the other of said members toward and away from blade clamping relation when the handle is rocked.

"2. A razor comprising a head consisting of a housing and a blade clamping member pivotally associated therewith, a handle for the razor, pivotally connected to the housing, and cam means on the razor handle for positively rocking the clamping member into and out of blade clamping relation with the housing when the handle is rocked.

3. A razor comprising a head consisting of a housing and a blade clamping member pivotally associated therewith, a handle pivotaliy connected to the housing, cam means on the handle for engaging a rear portion of the clamping plate when the handle is swung in one direction, and cam means in the handle for engaging a front portion of the clamping plate when the handle is swung in the other direction.

4. In a razor, a housing, a guard and blade clamping member pivotally connected with said housing, an extension on said housing, said guard and blade clamping member being formed with an opening for the protrusion of said extension, a handle pivoted to said extension, and cam means on said handle for rocking the guard and blade clamping member when the handle is rocked on its pivot.

5. In a razor, a housing, a guard and blade clamping member pivotally connected with said housing, an extension on said housing, said guard and blade clamping member being formed with an opening for the protrusion of said extension, a handle pivoted to said extension, cam means on the handle for moving the guard and blade clamping member into blade clamping relation with the housing, and cam means on the handle for moving said member into blade releasing relation with the housing.

6. In a razor, a blade clamping head, comprising a housing and a blade clamping member pivotally associated with the housing, a handle arranged substantially at right angles to said head when a blade is clamped between the housing and the clamping member, and means on the handle for positively moving the clamping member and thereby freeing the blade when said handle is moved from the mentioned right angle position.

7. In a razor, a housing having a top, rear and side walls, a member pivotally connected to said housing and having a front blade clamping portion and a rear portion, a downwardly reaching extension on said housing, a handle pivoted to said extension, cam means on said handle engaged with the front blade clamping portion of the mentioned member, and cam means on said handle engaged with the rear portion of said member, whereby upon movement of the handle about its pivot, the mentioned member is moved.
