is arcuately clamped between the clamping plate l4 and the guard plate [6.

The handle l3 of the razor construction of the present invention differs over the usual handle construction by the provision of jointed parts which maybe selectively locked or unlocked as desired.

As best shown in Figure 3,.the handle it has an upper handle portion 5? with interiorly threaded recess at one end thereof (not shown) and a rod-like portion i3 at its lower end. A circumferentially extending peripheral slot 19 is provided intermediate the ends of the rod-like portion It. An inverted U-shaped slot 2;) is provided in the rod-like portion is above the peripheral slot l9 with one leg ii of the U slot terminating in the peripheral slot it and its other leg 1 is either necessary or conducive to good results.

. Often, this excess pressure is the cause of shear- 'the. skin being shaved.

ing' slight protuberances or imperfections from In addition,the force exerted on the razor tends to force the skin to 22 terminating in spaced relation from thepe- V ripheral slot l9.

A cup-shaped sleeve 23, having its lower end 24 closed, slidably embraces the rod-like'portion I8. A small capscrew 25has a threaded shank 26 inserted through'a side Wall of the sleeve 23 withan inner end 21 thereof seating normally in the peripheralslot lS toslide freely thereinl If desired, a pin or other similar member may be It is preferred,

parts may be easily disassembled. The-lower end of the handle portion ll is provideo. with a reduced portion 28 for positioning one end of a coil spring the other end of which 'is seatedagains't the end wall "lof the sleeve 23.

The knob. 28 illustrated in Figure 3 tapers inwardly to seatingly receive therearound the end coil of the spring 29. Compression of the coil spring 29 normally maintains the slot engaging end 21 of the cap screw 25 against the lowerside.

This frictional engagement permits the sleeve Elite be rotated .around the upper'handle portion and serves If it is 'cie sired s lock the sleeve on the 'upper handle portion ii, the sleeve is rotated to a position in which the cap screw is in align- The sleeve of the springZi) whereby the slot engaging end t'l of the cap screw slides along the slot leg 2i. Whenthe inner end of the, cap screw 'engages with the end of the slot leg 2!, the sleeve 9.173 is rotated to the right to slide the end ofjthe cap When the inner end of the cap screw 25 has been turned to a position in alignment with the short slot leg 22, compressionof the spring 29 urges the sleeve member 23 away from the upper handle portion l'l until the cap screw engages with the end of the slotleg 22. The parts are then positioned as The sleeve 23 is thereby held againstrotation on the upper handle 'portion ll. These parts may be unlocked to provide free relative rotation therebetwcenby sliding the slot engaging end 2:! of the cap screw '25 through the slot 20 andinto the peripheral slot The handle partsare rigidly connected to each otheras shown in Figure 4" for the purpose of sembled or disassembled; After the parts are assembled, they are turned to the relative posiface.

assume the angle at which the blade holding head is held as the razor is drawn over the skin sur- In cases Where the skin is tightly drawn over the underlying bone structure or where the skin has lost its pliant characteristics due to age or other reasons, it will not flex with the angularly held blade holdinghea'd and will ofttimes result in a corner of the bladescratching or ugin the skin surface.

By providing a handle of the type herein de-' scribed and illustrated, the blade holding head is free for rotation relative to' the handle portion which is grasped by a user. Consequently, the user need only flex his wrist to a position in which the razor blade is held at an angle to the face which has been found to give the best shave. Any rotation of the blade holding head necessary to keep the entire cutting edge of the blade in contact withthe skin surface will automatically be'effected by .merelydrawing the razor over the skin surface to be shaved. As a result, less pressure 'need be exerted by the user and a better shave is effected without irritation of the skin surface; I

shown in Figure 'l', the sleeve 23 need not be in axial alignment along its entire length with the longitudinal axis of the upper handle portion I'L' The'lower portion of the sleeve 23 may be ,curved orangularly'offset as at 32 to provide the proper shaving angle when the handle is held jbytheuser'wihout anywrist deflection; In the jhandle const ruction illustrated in Figure 7, it is ohlyhecessary that the lower sleeve portion be angulalrly offset at a distance below the rod-like portion i8to permit relative axial movementbetween the sleeve'and the upper handle portion ll, when theparts are moved into locked or unlocked positions. f

' Likewiseythethreaded locking stud 15 may be an'gularly disposed relative to the blade clampingplane of the plate M for the purpose of offsetting the handle l3 toeffect the desired shaving angle.

Obviously, it is not necessary in shaving operations that the blade holding head ll be mounted on the handle l3 in such a manner that rotation of 360 therebetween is effected. For all 'practical purposes this rotation may be confined to a. maximum ofapproximately 30 as shown in the full and dotted line illustrations in Figure '2. The razorhandle construction illustrated iii-Figures 5 and 6- provides for such a limited rotation between the blade holding head II and the handle 332 "In this construction, the upper handle'portion 34 is provided with an intermediate circularportion 35 of reduced diameter. The end 36 extending "downwardly from the intermediate portion 35 is of the same diameter thereof but is ber.
