John H. Hilliard, New Yorin. N. Y., assigner to Y Magazine Repeating Razor Company. a corporation of New Jersey Application April 2s, 1935, sensi No. 18,126

' e claims. '(cl. en -4o) This 'invention relates to that class of magazine razor in which the magazine of blades is' temporarily attached to the^razor for the purpose of supplying a fresh blade, the razor being used for shaving apart from the magazine. j

The present invention is directed to a razor in whichkthe blade is held in proper shaving vposition to the guard by a movable part of the shaving head that is provided with a tapered portion l0 that exercises a wedging action against the back edge of the blade. The movable part is preferably made slidable in the "shaving head and is held in normal clamping position by a spring. The spring not onlyholds the movable part in contact with the blade but also holds the movable 4part against lateral movement.

The invention relates, further, 4to a co-operaltion between themovable part and a top plate over the blade that causes the said part to raise the top plate slightly thus relieving the pressure on the top of the blade when the wedgeis moved" out of. contact with a blade in the razor and also out of the path of travel of an incoming blade which latter blade is fed into the razor inrear of its position and is in turn moved forwardly to proper position when the wedge pushes it forwardly on the removal of the blade magazine. c

The invention is illustrated in the accompanying drawing in which Figure 1 is a cross-se`ction of. a' razor embodying my invention with the blade in proper shaving position relative to the guard. Figure 2 is a similar view with the blade in the position it occupies when fed into the razor and showing the actuating nger of the magazine in section and with the movable part lifted by the iinger. Figure 3 is a detail perspective Voi the blade magazine and the linger. Figure i is a longitudinal section of the blade magazine.

Figure 5y is a cross section of Figure 4. Figure 6 is a) perspective of the 'shaving head showing Figure l with the top plate and part of the blade rplatform broken away. Figure '7 ls a Across-section of a modied form of shaving head. Figure 8 is a similar view showing the wedging part raised and in contact with' the top plate to raise the latter. Figure 9 is a cross-section of another modication. Figure 10 is a detail perspective of the end of the blade magazine and its finger used with. the shaving head shown in Figure 9.

The shaving head comprises a. blade platform I0 with a guard II at its front edge' and a supporting plate I2. The supporting plate is from .'a back plate I3. They back plate is provided with a. top plate I4 preferably by Bending the back .plate over. The top' plate normally rests on the top faceof 'a blade I 5 when a blade is on the blade platform I0. It desired the stops I6 are placed at the iront corner of the blade platform to protect the corners of. the blade in case the cutting edge of the blade extends along the lull 5 length Yof the blade. The parts are relatively stiff and can be made from one piece of metal, bent over at the bottom to form a fold ,I1 toreceive a stud or screw IB of. ahandle I9. The movable part 20 fits in the space between the sup- 10 porting plate I2 and the backplate I3 and. is usually made to slide vertically. The movable part 20 has Aweclging-p'tions II which engage the back` edge of the blade and push it forward and also hold it then under the influence of a spring. 15 A I show a spring 22 fastened to the under side of the blade 'platform and `exnding rearwardly through a hole in the plate I-2\and into a slot 23 in the movable part. Thisv spring not only holds theY movable part down but also prevents side -20 movement of the said part. Y

The magazine is in the main not new and comprises a casingrM in which the stacl: 25 of blades is housed and held against the` slotted top 2li by a spring il. The top has a. slot 29 in which the lip 25 3o slides. The lip is on the grip 3i and forms an ejector, as it engages the rear edge oi the top plate of the stack and slides the blades out through a slit 32 in the front wall oi the magazine when the grip is slid forwardly. The magazine 3@ is provided with a Enger 33 with a tapered end for ready and easy insertion in the razor head.

The razor head has an opening for receiving lthe finger t3 formed by the recess 3d in the supporting plate l2 and the recess 3B in the movable part 35 2d. These recesses are normally not aligned but when the ilnger 33 is inserted, its taper forces the movable part upwardly, the front inclined face of movable part is raised and its contact with a blade in shaving position is lost. The slit 32 in the 40 act to limit the forward movement of the blade. 50

The wedging portion' is usually placed only at the ends of the movable part 2D as shown in Figure 6, although the wedglng portion may extend the width of the shaving head. The parts of the shaving head may be made still as the resiliency of the 55 foot 36 on Ythe bottom of the stem. The shaving f head is recessed at 31 to receive the finger 33 of the magazine. Whenthe finger is inserted, as in Figure 8, the movable part 20 is raised, it engages the top plate Il, the blade in the razor is released and a fresh blade is inserted. On the withdrawal of the finger the spring 3| returns the wedging portion to its normal position whichl allows the spring top plate to engage the top face of the blade with sufficient pressure to hold the blade firmly in place. v

In Figure 9, I show a modification in which the movable part moves downwardly to release the blade, the movable ypart retreating against the influence of the spring 38 when the finger 39 is shown canted relative to the slit 32 which' causes the blade to be fed at an angle. This is donev when it is desired to have the blade platform and the blade inclined downwardly relative to the handle. This is clearly evident from Figures 9 and 10 showing the slot 40, and blade platform I at the same angle as the finger 3! and the slit 3(2 of the magazine.

Various details may be varied without dep ing from the scope of the invention as set forth in the claims.

I claimt- 1. A safety razor comprising a holder for maintaining a blade in shaving position, a slidable part in the holder, said part including a wedge for yieldingly maintaining the blade by engagement with its back edge, a blade magazine having means for ejection of a blade. and a finger on the magazine and insertable in the holder and having aV surface for moving the slidable part out of engagement with the blade. 2. A safety razor comprising a blade holder having a blade platform, a back piece spaced from the blade platform, a 'slidable part in the space, the
