RAZOR.

Application filed April 14, 1924. Serial No. 706,366.

useful Improvements in Razors, of which.

the following is a specification. My invention relates to improvements 1n razors, with more particular reference to those of theselt-stropping type, and the .ohject of my invention is to devise a razor of this character provided with self-contained means whereby the blade may be disposed at an oblique angle to the'st rop when sharpening it, thus ensuring a much sharper edge than is obtainable where the blade is disposed at right angles to the strop, as at the present time, due to the fact that the oblique position of the blade is the logical one when stropping. j

I attain this object by the construction illustrated in the accompanying drawings in which Fig. ,1 is a view of an auto-strop razor embodying the invention, the blade being in the shaving position.

Fig. 2 is a view"showiug the blade in the stropping position.

Fig. 3 is an enlarged detail view of the improvement separated from the razor frame. the blade being in the horizontal or shaving position.

Fig. 4 is a view similar to Fig. 3 with the. blade in the oblique or stropping position.

Fig. 5 is a view looking on the left hand end of Fig. 3.

Fig. 6 is a view looking on the right hand eudot Fig. 3.

Similar figures of reference indicate similar parts throughout the several views.

The razor illustrated is of a well-known auto-strop type the operation and handling of which requires no extended description beyond stating that the pressing down of the thumb lever (not-shown) at the rear. of the frame withdraws the blade 1 out of the two

clips

2 and 3 so that it swin s free with the shaft 4 to which the blade older .is permanently secured, which shaft is provided with the small gear 5, and on in serting the strop and movin the frame back and forth thereon the b ade flips alternately on one side and the other of the shaft 4 and is thus sharpened on both edges. It will be noted. however, that with this construction. the blade. whenostropping. lies horizontal across .the strop, that is, the edge of the blade and the longitudinal axis of the strop are at'right angles. This, of course, is self-evident and may be confirmed by observation.

However, it is well-known that this position of the blade is not the logical or correct position for properly and effectively sharpening the blade, and it may be pointed out that. having reference to the old style razor, the blade. in the hands of an experienced 'man. is always stropped on both strokes with the edge held diagonally across the strop, that is, at an oblique angle thereto; this improvement, therefore, permits the auto-'strop razorv blade to be strapped in the logical 'manner just described.

According to the present invention the blade 1 is detachably held in the usual manner in the present style blade holder 6 but this holder is extended into a flattened openended sleeve-like portion 7 having a longer .opening'8 at its right hand end than the opening 9 at its left hand end. The shaft 4 extends through the sleeve in the usual manner but instead of the shaft being secured to the sleeve as at present it is free of it, being flattened, however, on two sides as at 10 and 11 so that when partially rotated the sides will grip the sleeve walls and flip the sleeve and consequently the holder and blade over on the alternate stropping strokes. Between the shaft 4 and the inside front edge of the sleeve recess is inserted a bowed spring 12, as shown more particularly by the dotted lines in Fig. 4.

The blade is seated in the clips 9. and 3 as usual for shaving. but when it is desired to strop it it is withdrawn fromthe clips in the well-known manner by operating the thumb lever at the rear of the frame where.- upon the spring'12, which is compressed 'when the blade is in tho shaving position. as

shown in Fig. 3, throws the blade holder 6 and sleeve 7 forward so that the sleeve travels at its right hand end the full length of the opening 8, being held at its opposite end as the opening there is short, so that the blade 1 then lies at an oblique angle to the strop when the-latter is inserted and may then be 'stropped while remaining in the oblique position, as shown in Figs. 2 and 4. After stropping it may be returned to the shaving position, as shown in Fig. 1, in the well-known manner. a

' From the foregoing it will be seen that I have devised a simple, practical, and efiicient means capable of incorporation in the auto-strop type razor with great facility which enables the blade to be stropped and sharpened in the logical and correct manner without necessitating removal of theblade from theframe.

Vhat I claim as my invention is:

1. A razor comprising a frame, partially rotatable 'gear connected upper and lower transverse shafts carried by said frame the upper shaft being flattened on opposite sides, an open-ended flattened sleeve freely mounted on the said upper shaft and contacted 3. For use in a razor of the character described having a frame and a. transverse shaft friction-operated by longitudinal contact between the frame and a strop, an openended flattened sleeve provided at its for- 'ward edge with a blade holder having its opening at one end longer than the opposite end opening, and a shaft flattened on opposite sides extending freely through said sleeve adapted to be mounted on said frame above the friction-operated shaft and placed in operative connection therewith.

4. For use in a razor of the character described having a frame and a transverse shaft friction-operated by longitudinal contact between the frame and a strop, an openended flattened sleeve provided at its forward edge with a blade holder having its opening at one endlonger than the opposite end opening, a shaft flattened on opposite sides extending freely throughsaid sleeve adapted to be mounted on said frame above the friction-operated shaft and placed in operative connection therewith, and a spring between the inside front wall of the said sleeve and the flat-sided shaft,
