Application ile September iQ, 1911, Serial No. 650,843. Renewed March 26, 1918. Serial No. 757,047.

To all wlzom t may concern:

Be it known that I, GnoRGn H. Tum, citizen of the United States, residing at Lincoin, in the county of Lancaster and State of Nebraska, have invented certain new and useful Improvements in Vibratory Safety- Razors, of which the following is a specification.

This invention has relation to safety razors, and has for its ob'ect to provide a razor so constructed that t e blade will move within the guards back and forth in a direction at a right angie to the cutting edge of the blade.

The partsy are so arranged that the blade will move at a-rapid rate of speed, and thus as its cutting edge is brought in contact with the hairs upon the face of a user the hairs are severed and dragging of the skin or upon the nerves is eliminated.

The parts of that they may be readily disconnected tor cleaning and other purposes, and in addition to the advantages heretofore stated the razor may be used without means for vibrating the blade if such vibrating means is not at hand or obtainable. I

In the accompanying drawing z-Figure 1 is a side elevation of the razor; Fig. 2 is a side elevation of a plug which may be used upon the handle of the razor; Fig. 3 is a perspective view of the razor, with parts separated; Fig. 4 is a perspective View of the blade; Fig. 5 is a perspective view of a vrocker arm which is a component part of the razor; Fig. .6 is a longitudinal sectional view of the razor; Fig. 7 is a perspective view of the lower guard plate used upon the razor.

lFurther objects and advantages will appearA in the following description it being understood that various changes may be made in the construction, arrangement and combination of the parts without depart-ing from the scope of the appended claims.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawing by the same refe-rence characters.

The razor includes a flexible cord 7 which is attached to a suitable motor or rotary mechanism of any well known construction (motor not shown) and operates through an outer casing 6 which ends in a plug 16 forming part of the handle of the razor. The rothe razor are so constructed `gether in a tations of the cord 7 are transmitted through a' shaft 15 loosely entering a socket 19 to the shaft 13 which ends in a beveled circular head 14 which is free to rotate butcannot move lengthwise toward the either end of the handle on account of the collar 21 and the spring 12. The shaft 11 with its head 2O does not rotate but is free to move lengthwise to compensate for the agreement or disagreement of the beveled ends of the circular heads 20 and 14, the two heads being kept in contact by the action of the spring 12. The endwise thrustings of the shaft 11 are transmitted through the handle 4 to the lug 10 of the rocker arm 8 (shown in detail in Fig. 5) which reverses the movement and also transfers the motion from the angle of the handleto that of the blade in order that there may be no unnecessary friction or buckling of the parts. The arm 8 is journaled in the bearings 9. A barrel 5 is screwed to the handle 4. Thelower ends of the rocker arm 8 Fig. 5 penetrate the holes in the blade 2 and thus transmit the forward and backward motion to said blade at a high rate of speed.

The blade is held in position by the arms 8 penetrating the holes 17 and by the guards 1 and 3 which snap together through the :action of the lugs 18 and notches provided on their edges and hold the parts firmly topositive position relatively to each other and with the blade. As the razor -is brought forward over the face in the ordinary manner of the ordinary safety razor the edge of the blade advances and recedes in an extremely rapid manner and at each advance severs a few hairs and immediately recedes so rapidly that the skin is brought back to the normal position before the drag of the hair can be transmitted to the nerves of the face to cause pain. Furthermore, it has been demonstrated that the greatly increased speed of the movements tend to render the razor more safe from cuts and injuries to the face, it being practically impossible to cut or injure same by reason of the vibratory result-s of the said movements.

The power required to operate the mechanism is very slight and may be obtained from any well established source, such as a small electric motor operated by dry cells or batteries or by an electric current taken from an ordinary light bulb socket7 or by any mechanism, giving a suitable speed of rotation. It has been found that an infinite variation in the number of rotations of the cord is possible Without sacrificing the eiliciency of the razor although it is probable that a speed of from 500 to 2000 revolutions per minute will give the greatest efficiency and economy.

In case of failure of the motor power, or if for any reason it be desired to operate the razor without the vibrating motion, the plug 16 may be unscrewed and the button plug 16 shown in Fig. 2 substituted in its place, resulting in a more attractive and pleasing safety razor than is ordinarily encountered.

Having thus described the invention, what is claimed as new is:

1. A razor comprising a blade mounted for reciprocation, a handle, a shaft slidably mounted in the handle means operatively connecting the shaft with the blade, a beveled head fixed to the shaft, a second shaft journaled for rotation in the handle, a beveled head carried vby the last mentioned shaft, the beveled surfaces of said heads being toward each other, means for rotating the last mentioned shaft, and means for resiliently holding the first mentioned shaft toward the last mentioned shaft.

2. A razor comprising a handle, a blade supported for reciprocation thereon, a shaft mounted for sliding movement in the handle and operatively connected with the blade, a beveled head carried by the shaft, a barrel detachably connected 'with the handle, a shaft journaled in the barrel, means for rotating the last mentioned shaft, a beveled head carried by the last mentioned shaft, the beveled surfaces of the said heads being disposed toward each other and resilient means for holding the heads in engagement with each other. f

3. A razor comprising a handle, a blade mounted for reciprocation thereon, a shaft slidably mounted in the handle and operatively connected with the blade, resilient means for holding the` shaft in a normal position, a barrel detachably connected with the handle, a shaft journaled in the barrel for rotation and o eratively engaging the irst mentioned shaft to reciprocate the first mentioned shaft as the second mentioned shaft is rotated, a third shaft journaled in the barrel and slidably engaging the second mentioned shaft, and means for rotating the third mentioned shaft.

In testimony whereof I afx my signature in presence of two witnesses.
