I the magazine by a separating movement of the magazine and razor and allowing the-blade to settle itself upon the-blade seat of the razor-i being correctly positioned by the blade-locating bar; 'It will be observed that in carrying out'th-is process the only contact withthe blade is that required for the partial ejection thereof an that this-is effected by contact only with the 'fiat'face of-the blade while its shaving edges are safely" concealed and protected. Complete removal of the blade from the magazine is effected by eng-ag ement of a razor part with an internal edge of the blade, and here again in this stage of the transferring process there is no danger of con tactwith the shaving edge of the blade and noreason for such contact. 0n the contrary, the" entire: transferring process is carried out by engaging the surface and internal edges ofthe bladein areas or at locations remote from-its cutting edges; Preferably and as herein shown; the safety razor may be equipped with a hook shaped element designed for convenient and secure engagement with the partially ejected blade; and the magazine may be provided with guiding means-- which insure or assist in locatingthe'r'nagazine in the safety razor in the most advantageous relation for effecting the transfer" of a blade from one'to the other. I

' These and other features of the inventionwilP be best understood and appreciated from the following description of a preferred manner "of carrying out the process of the present invention as-illu'strated inthe accompanying drawings; inwhich' Fig. l is a view in perspective showing a magazine and safety razor assembly with a blade partially ejected from v the magazine and engaged b'y-the'razor;'

Fig. 2 is'a corresponding view showing the reference may be had for further details of its ccnstruction. It comprises a handle l0 carrying v a s'iubstantially flat guard member which provides" tliefbladeseat' of. the safety razor. Rising} through. a slot in thebl'ade seat is the elongated;

blade-locating bar I2, this being carried by a L longitudinally, movable spindle. l3 havinga tapera my d in Pli' iiiflql llh; merrier gd. s own aE a Tlj b r... s.

provided at each end with an overhanging shoulder 24 giving it a hooked formation. Preferably and as herein shown the hooked formation is effected by an indentation in the end wall of the bar [2, the upper edge or wall of the indentation being comparatively short and extending inwardly, and the lower edge or wall comparatively long and gradually inclined outwardly, thus providing a guide edge or surface for directing the blade downwardly into position on the blade support or seat. The cap of the razor comprises sections l4 and i5 pivotally mounted on a spider 23 which is carried by and moved by means of the spindle I3. In Figs. 1 and 2, the cap sections I4 and 15 are shown in their open position and it will be understood that after a blade has been positioned upon the blade seat the cap sections are closed and the blade transversely flexed and held in shaving position.

The blade magazine I6 is rectangular in outline and provided with a thumb opening I! in its upper wall and a blade-exit opening H3 in each of its end walls. As supplied to the user, it contains a stack of ten or twenty thin, flexible doubleedged blades 2| having an elongated median slot 22 and unsharpened end portions of reduced width as compared to the body of the blade. These blades are maintained in staggered relation within the magazine and may be ejected, one by one, through the blade exit slot 18 by traction exerted on the upper surface of the uppermost blade in the stack by the finger or thumb of the user. The blade stack is maintained in the magazine with the shaving edges of the blade carefully spaced from the walls of the magazine by an upstanding rim 25 of substantially the same narrow width as the blade-locating, and in its ejecting movement each blade is safely guided by engagement of its slot with the rib Z5 and also by a centrally disposed rib l9 projecting downwardly from the upper wall of the magazine. The outer end of this rib is shown in Fig. 3. The rib l9 at the exit slot, the rib 25 within the magazine,

and the blade-locating bar l2 of the razor are all of substantially the same width, that is to say, they are designed to receive with slight clearance the median slot 22 of the blades being handled.

The magazine is provided with external guiding means herein shown as a groove 20, shaped to receive the upper edge of the blade-locating bar l2 and to center the magazine thereon. It will be apparent that any cooperating guiding elements provided respectively in the safety razor and the magazine would be satisfactory for effecting this purpose.

In carrying out the process of transferring a blade from the magazine to the razor, the user first partially ejects the uppermost blade from those contained in the magazine by surface engagement exerted through the opening ll as suggested in Fig. 1. In this movement, the blade is guided by the internal rib 25 of the magazine and the guide rib I!) at the exit slot. The magazine is then presented to the open razor and registered in the proper transverse position by engaging the groove 20 of the magazine with the top edge of the bar 12, at the same time hooking the end of the bar through the slot of the blade, all as suggested in Fig. 1. In these preliminary steps, the engagement of the groove 20 with the bar [2 aligns the blade-locating guiding ribs 25 and IQ of the magazine with the blade-locating bar 20 of the razor. The user now draws the magazine and razor apart, moving them from the position shown in Fig. 1 to some such position as that shown in Fig. 2. In this separating movement from the cutting edges of the blade.

4 the blade is fully Withdrawn from the magazine and as soon as it is freed therefrom it passes freely over the bar [2 and settles itself in position upon the blade seat I l, where it may be immediately clamped and retained in shaving position.

It will be observed in carrying out the process above outlined, the user engages only the fiat surface of the-blade in the magazine and it is impossible for him to contact the sharp edges of the blade. Similarly, when the ejecting force is transferred to therazor the engagement of the blade is through the medium of an internal edge provided by the blade slot 22 in a location remote The result is that the blade is controlled positively throughout its ejecting movement so that its shaving edges are carefully prevented from accidental contact and that it is delivered in final shaving position in intact condition. .I-Iaving thus disclosed my invention and-describedin detail the preferred manner of carry; ing out my novel.- pr ooess, l claim as new and desire to secureby Letters Patent: 7
