The guard member is provided tion; with a slot through which extends a headed stud Fig. 3'is a corresponding view in rear elevation, II which is fast in the blade carrier and by showing portions of the handle broken away; depressing this stud the blade-carrier may be 55 swung downwardly and forwardly into blade receiving position as shown .in Fig. 2. The blade seat I6 is provided near its outer cornerswith a pair of projecting guard lugs 22 which mask the corners of the blade and so protect the user from being cut or scratched by them. The blade seat is also provided at one end with a pair of spring fingers 23, shown on a large scale in Fig. 12, and adapted to engage one end of a blade placed upon the blade seat and to hold it frictionally in place thereon pressing yieldingly and longitudinally against the pins l3.

It will be understood that the blade holder may be swung into its place receiving position as shown in Fig. 2 by pressure upon the stud 2| and that a blade 50 may then be positioned upon the pins l3 by placing it on the blade seat and forcing it slightly toward the left as'seen in Fig. 1, placing the spring'flngers 23 under tension and bringing the blade apertures into registration with the pins l3. When this has been done and pressure upon the stud 2| released, the blade holder immediately swings upwardly carrying the edge exposure for the blade.

A preferred embodiment of the blade magazine or clip of my invention will now be described and then it will be explained how this may be utilized for supplying a single blade at a time to the razor already described. The magazine may v be formed substantially or entirely of sheet metal.

It is generally rectangular in form and square in cross-section, having a front wall 30 which terminates in a flat intumed flange 3|. The magazine has also a topwall 32 and a rear wall 33 which is extended downwardly below the edge I of the front wall 3|! so that it provides a guide or positioning flange projecting below the body of the magazine. The rear wall is also provided with an intumed flange 34 corresponding to the flange 3| of the front wall and spaced therefrom so as to expose the body portion of the lowermost blade in the pack by a distance just equal to the width of the rib l8 on the blade seat of the razor. In eifect the bottom of the magazine is slotted or apertured to the width of the space between the inner edges of the flat flanges 3| and 34. The rear wall 33 is also provided with an external rib 35 which is located slightly above the level of the flange '34. It is herein shown as a solid rib but may be formed as corrugation in the metal of the magazine. From the description thus far it will be seen that the magazine is adapted to contain a pack or stack of blades 50 arranged longitudinally one above another. the lowermost blade being supported by and exposed between the inturned flanges 3| and 34.

The inturned flanges u and u of the magazine are out oif somewhat within the left end of the magazine as shown i'nFig, 8-and are providedat theirright end with downtumed ears or books 4| which act as stops to limit the movement of the magazine toward the left upon the blade seat of the razor. The'flanges are cut 011 at their left ends to facilitate disengagement of the blade when the magazine is retracted, as will be presently explained, and to eliminate the danger of prying up the blade upon the blade seat by acci dental tilting movement of the magazine at the end of its withdrawing movement. At its right end the magazine is provided with a long end walLor lug 31 which extends from the top 32 of the magazine downwardly beyond the end of the lowermost blade supported upon the flanges 3|,34. The magazine is correspondingly provided at its left end with a shorter end wall or lug 36 which is of such length as just to clear the lowermost blade in the pack and so permit that blade to be moved endwise beneath the lug, or to permit the blade to remain at rest while the magazine is moved endwise to reliquish the blade. The magazine is also provided internally upon its front wall 30 with a pair of spaced vertical bladeguiding ribs 39 which are arranged to engage the sharp edges of the blades in the stack only at their extreme outer corners in such manner that the cutting edge as a whole is prevented from -coming in dulling contact with the magazine.

The guide ribs 39 also terminate in position to clear the lowermost blade in the pack and so leave its cutting edge entirely free for the retracting movement of the magazine. The magazine is also provided with a curved-leaf spring 40 located below its top wall and tending at all times yieldingly to press the blade pack downwardly and maintain the lowermost blade in contact with the flanges 3| and 34.

It will be understood that the magazine is loaded with a stack or pack of perhaps ten loose unwrapped blades. These are enclosed by the walls and top of the magazine except for a central longitudinal zone in the undersurface of the lowermost blade in the pack.

In using the magazine above discussed to supply blades to the razor of Figs. 1-3, the stud 2| is depressed to swing the blade carrier forwardly into blade-receiving position and the magazine is placed upon the blade seat with the wide flange formed by its rear wall 33 in contact with the rear face of the body portion M of the blade carrier, as best shown in Fig. 11. The magazine may be placed in this position and then pushed toward the left as seen in Fig. 1 being guided in this movement by its downwardly extending flange. The stud 2| is now released and the blade carrier will be moved rearwardly with the magazine until the rear wall of the magazine encounters the forward edge of the flange 3 of the guard as shown in Fig. 11. The flange l3 engages the magazine just above its external rib 35 and, therefore. tends not only to push it forwardly upon the blade seat but to hold it down against removal. The movement of the magazine toward the left is continued until arrested by engagement of the stops 4| against the right hand edge of the blade seat. This movement of the magazine is gauged by the stops so that the lowermost blade;

ill in the magazine is forced at its end against the spring fingers 23 displacing them outwardly and itself coming into registration with the pins l9. It will be noted, that in this movement the spaced flanges 3| and 34 of the magazine engage between them the rib l8 of the blade seat, all as In this movement the magazine is again guided by the contact of its downwardly extending flange with the body portion 4 of the blade carrier and by the engagement of its flanges 3! and 34 with the rib l3. During this movement it is also held against displacement by the engagement of the flange l3 of the guard with its external rib 35.

Movement ,of the magazine toward'tbe right is 7 continued until the magazine is entirely withdrawn from the blade, the latter under the wall-2i and being left in shaving position without any damaging contact with its shaving edge. Pressure of the spring at once replaces the delivered blade in the magazine by the second blade in the pack when the magazine has been drawn clear of the guard member of the razor. When the magazine has been moved to the right sufliciently to clear the razor the spring 20 is effective to restore the blade carrier and the blade to shaving position beneath the flange I! of the guard as shown in Fig. 13 and the razor is ready for shaving.

After shaving, the used blade from its seat either by prying up one end of the blade sufliciently to disengage one of the pins I9, or by smartly shaking the opened razor so that the frictional engagement of the fingers 23 is overcome to the extent of releasing the blade.
