. SAFETY nazon.

Original application filed September 26, 1923, Serial 110,664,972. Divided and this application flied July 24, 1925. Serial No. 45,887.

My improvement relates to a safety razor structure wherein provision is made -fo r conveniently turning the blade so as to bring first one side and then the other side of the blade against the face during the shaving o eration, whereby the blade may longer be ept in cutting condition.

Structures for this purpose are described in my Letters Patent, No. 1,489,102, dated April 1, 1924, and in my Letters Patent, No. 1,492,233, dated April 29, 1924. In those structures the blade is held by a holder which is attached to and turnable on the supporting frame. In the construction of 1 the present application, the blade holder 13 easilydetachable from the supporting frame for turning the holder and thereby reversing the blade.

This application is a division of my application, Serial No. 664,972, filed September In the accompanying drawings, Fig. 1 is a perspective showing the frame and the upper part of the handle of a structure embodying my improvement;

Fig. 2 is a perspective of the guard plate; Fig. 3 is a perspective of the blade and handle;

Fig. 4 is an upright section along the mlddle longitudinal line of the blade;

Fig. 5 is an upright section on the l1ne, 5--5, of Fig. 4, looking toward the left;

Fig. 6 is a section on the line, 6-6, of Fi 3;

Fig. 7 shows the upper part of Fig. 4 in another form.

Referring to said drawings, the structure shown is of the Gillette type and includes a flexible blade having two cutting ed es, and means are applied to that blade or conveniently removing the blade from ts support, turning the blade, and then replacing it.

- But it is to be noted that my structure embodies several well-defined features not present in the Gillette structure.

G is a handle having a screw-threaded neck, G At the u per end of the neck 1s a cylindrical lug, at the lower end of which is an annular shoulder, G.

H is a spider-form top plate support comprising an interiorly threaded bearing, H and three arms, H on the upper end of which isthe top plate, H. The neck, G, of the handle is screwed into the bearing,

H as shown in Fig. 10. The top plate is in the form of an elongatedparallelogram and it is crowned between its long edges. In the lower face of the top plate in its middle longitudinal line, is a socket, H, which is adapted toreceive the upper end of the cylindrical lug, G On the same line near one end of the top plate is a socket, H which receives a lug described further on. At the other end of the top plate and on said line there is formed in the lower face of the top. plate a channel, H, which receives the upper part of the fork=form bolder described further on. The guard, I, is in the form of an elongated parallelogram a little wider than the top plate and toothed along its long edges and crowned between its long edges to conform to the crownin of the top plate. Near one end the guar has on its upper face a lug, I. At its other end, the guard has in its upper face a channel, I corresponding to the channel, H. In the channel, 1 is a lug, I. Atthe middle of the middle longitudinal line of theguard is an aperture, I.

J is the blade. This is ofapproximatel the length and width of the guard and each of its long edges is a cutting edge. Near each end of the blade, in position to receive the lug, 1 or the lug, P, of the guard, is an aperture, J At the middle of the middle longitudinal line of the blade isan aperture, J in position to receive the cylindrical neck, G of the handle. To the blade handle, J", is attached a fork-form holder, J the arms of which are flat and flexible. (Figs. 4 and 6.) On the inner end of one of said arms is a lip, J, directed toward the other arm. The holder receives one end of the blade, and the arms of the holder are long enough to bring the lip, J into the adjacent erture, J the lip bearing against the wal of the aperture which is nearer the adjacent end of the blade. By this means the blade handle is firmly held and the aperture, J,

lug, G entering the blade aperture, I, and

the lower arm of the holder going into the channel, I, and'the lugs, I and I, entering the-apertures, J ,'of the blade. Then the handle, 'G, is turned to drive it upward to is left open to receive the lug, I, on the liftthe guard and blade, whereby the blade is pressed against the lower face of the top plate, the lug, I, entering the socket, H,-

and the lug, I, and the upper arm of the holder, J, entering the channel, H, of the top plate. While the handle, G, is being thus driven upward, the lug, G being free in the aperture, I, of the guard plate and the aperture, J of the blade, the annular the blade. This relationship also functions for giving stability to the structure composed of the top plate, H and the three arms, H due to flexibility of the arms, H whereby lateral movement relative to the handle, G, is limited or avoided. If the lug, G fits closely, such lateral movement is altogether avoided, and if said lug does not fit closely, such lateral movement is at least limited.

When, 'durin use, the blade is to be reversed, the han le, G, is turned for retracting until the guard has been lowered sulficiently to release the blade and allow it to be moved in the plane of the blade. Then the operator grasps the handle, J withdraws the blade horizontally or in the plane of the blade, gives the blade a half turn on its longitudinal, middle line, and then returns the blade, by movement in the plane of the blade, into its position on the guard. Then the operator again turns the handle to drive'it upward to press the guard and the blade into working position. If, whenthe handle has been lowered, the guard is turned a little on the axis of the handle, the blade may be removed and replaced by endwise movement.

At the end of the top plate, H which has the channel H", there is only one arm, H and that is at one side of the channel, H. Thus space is made for the handle, J and for inserting and removing the blade.

In Fig. 7, the construction is the same as in Fig. 4,.excepting that apertures, I are substituted for the lugs, I and I, of the guard and downward-directed lugs, H, are placedon the lower face of the top plate, H, to extend downward through the apertures, J of the blade and into the apertures, I, of the guard, I.

The top .plate constitutes a relatively stationary blade-supporting member against which the blade is laid flatwise, and the guard and the handle constitute releasable means for engaging the blade and holding it against the relatively stationary bladesupporting member. The blade has a handle which is in the plane of-the blade, and the insertion and removal of the blade are accomplished by moving the blade in the plane dle extending upward through and threaded into said bearingand having its upper end in the apertures of the guard and the blade and engaging and pressing the guard upward, substantially as described.
