SAFETY RAZOR Application filed May 11,

To all whom 2'25 may concern:

Be it known that I, CHARLES E. CARPEN- run, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Safety Razors and the like, of which the following is a specification. V I

This invention has to do with certain improvements in safety razors and the like.

The invention has to do especially with improvements in the construction and arrange ment of the guard and the means by which it is supported together with the blade.

I11 connection with the construction of the guard, one of the objects of the invention is to so form the guard that the teeth of the guard will not interfere with the proper cutting function of the edge of the blade throughout its entire length. In this connection, it may be stated that in previous construct-ions of safety razor guards with which I am familiar, the teeth of the guard have interfered with the proper cutting function of the edge of the blade immediately adjacent to them. One of the objects of the present invention is to overcome this difficulty by freely exposing the entire edge of the blade, so that the'shaving will not be Streaky.

Another object of the invention is to provide a construction of safety razor holder such that it may be very conveniently used for shaving at an angle and also for shaving in different directions, the handle being adjustable with respect to the guard, so that the angle of the blade can be immediately shifted into whatever position momentarily suits the convenience of the user. In this connection, an object is to provide the handle itself with a bent or angular head piece on which the guard and blade are pivotally mounted; and more particularly in this connection, to form the head piece at an angle of approximately with respect to the length of the handle.

Another object of the invention is to provide an arrangement such that t -e blade can be very easily inserted or removed with re spect to the guard, and such that the act of turning the handle out into the working position will itself automatically lock the blade to the guard. In connection with the foregoing, it is a further object to provide an arrangement of guard and handle which can A CGBPOEATION OF ILLINOIS.

be folded-into a practically fiat package of small size convenient for carrying in a travelers kit.

Other objects and uses of the invention will appear from a detailed description of the same, which consists in the features of construction and combinations of parts hereinafter described and claimed.

Referring to the drawing:

Figure 1 shows a perspective view of a handle and guard embodying the features of the present invention, looking up at the back side of the guard;

Fig. 2 shows a side elevation ing to Fig. 1;

Fig. 3 shows a cross section on greatly enlarged scale through the guard and through the blade and the upper portion of the handle. In this figure the handle is also shown in dotted lines in the position into which it may be turned to interlock the blade.

Fig. 4 shows a view taken on the line 4.4 of Fig. 3, looking in the direction of the arrows, but on somewhat smaller scale. In Fig. 4 I have also shown by dotted lines two other positions into which the guard and blade may be turned; and

Fig. 5 shows a front face view corresponding to Fig. 4.

The handle 6 is made of any material and shape convenient for manipulation. Its upper or head end 7 is turned over at an angle of approximately 4045, as shown in Fig. 3 in particular. The extreme end 8 of the head is squared off at right angles to the axis of the head portion 7 but the lower corner 9 of the head portion 8 is cut away sharply, as shown particularly in Fig. 2.

The head portion is preferably slotted as shown at 10 to receive a pin plate 11 which is pivoted within the slot on the pin 12. Consequently, this pin plate 11 may be rocked in the slot. Examination of Figs. 2 and 3 in particular will show that the pin 12 is con- 100 siderably closer to the lower cut away corner 9 than the top squared surface 8 for the purpose to be presently explained.

The guard 13 is preferably made of sheet metal such as sheet steel, nickel or silver 105 plated. Its upper edge 14 is preferably curved forward; its central or body portion 15 is preferably bulged to the rear; and its lower edge is preferably provided with a correspondseries of guard teeth 16. These guard teeth commence substantially at the point 17 where the bulged portion 15 terminates, and the teeth are then bent rearmirdly, as shown at 18, so that the entire set of teeth together provide a longitudinally extending depres sion or pocket 19, as clearly indicated in Fig. 3. The extreme lower ends 20 of the teeth are preferably enlarged or bent to the rear, as clearly shown in Fig. 3, so as to avoid any possibility of cutting or injuring the face of the user.

'The blade 21 sets immediately in front of the guard as clearly shown in Fig. 3, its lower edge 22 lying adjacent to the pocket 19. Nevertheless, the blade is supported immediately adjacent to the lower edge and at the point 23 where it rests against the lower portion 17 of the bulge 15 of the guard. The entire length of the cutting edge 22 is therefore freely exposed. so that the cutting operation is most e'liiciently performed, but

the lower ends 20 of the teeth 16 guide the movements of the cutting edge with respect to the surface of the skin.

The upper edge of the blade rests against the curved socket portion i i of the guard. or as in.the construction shown in the figures. the upper portion of the blade is provided with a reinforcement 24; which rests in the socket ll and serves in effect as a pivotal or hinge support for the upper edge of the blade.

The pin plate 11 is provided with a pin 25 which reaches forwardly through a hole in a depression 26 in the upper portion of the guard. A collar 27 is formed on the pin 26 just above the socket 26 to prevent the pin from drawing backwardly through the hole. A collar 28 surrounds the pin plate at the back side of the depression 27 and receives the direct pressure from the head of the handle. The hole in the depression 26 is of substantial size as compared to the pin plate, so that a sufficient freedom of movement is allowed to enable the pin plate to rotate or move in and out freely through the hole.

The front end of the pin 25 is provided with an enlarged head as shown in Fig. 3; and the upper portion of the blade 21 or of the reinforcement Q l is provided with an opening 30 of sufficient size to pass the head 29. This opening 530 communicates laterally with a slot 31 of smaller size, so that after the blade and the reinforcement have been set into place, these parts can be shifted laterally in order to engage the head 29 on the slot 31.

The length of the pin 25 is such with respect to the shape and size of the head member 7 that when the head member is turned down substantially into the dotted line posi tion of Fig. 3, the pin plate is released to a sufficient extent to remove the pressure of the head 29 on the blade, and thus permit the blade to be either inserted or removed with facility. On the other hand, the proportioning is such that when the handle is turned out into the working position shown by the full lines of Fig. 3, the pin plate is drawn back so as to draw the head 29 firmly against the blade; and by reason of the fact that the pressure of the head 29 is applied at a point intermediate between the socket let and the supporting point 1? on which the lower portion of the blade rests, the blade will be deflected a slight amount by the pressure of the head29, thus exerted on the blade. This deflection of the blade will in itself cause its cutting edge to deflect a slight distance away from the pocket 19 of the guard, so as to still further improve the clearance at that point.

Owing to the fact that the guard and blade are pivoted with respect to. the head mem her, they can be turned into any convenient position for the best shaving, as is clearly evident from Fig. l. v

hen the parts are to be packed up into a small space, the guard and handle portions may be laid substantially flat together, and the guard can be turned into position parallel to the handle so as to bring all of the arts into the smallest space possible.

Vhile I have here-in shown and described only a single embodiment of the features of my present invention, still I do not limit myself to the same except as I may do so in the claims.
