7 Claims. I

This invention relates to a magazine unit for use with a razor having a chamber therein adapted to receive the magazine unit and having means for positioning successive ones of a stack of blades in the magazine in shaving position on the razor. The invention contemplates a magazine adapted to receive a stack of razor blades therein and having means for releasably confining the blades within the magazine. The end walls of the magazine have a part thereof engageable with the top blade of the stack of blades so as to retain the blades within the magazine. The end walls are also provided with portions thereof engageable during insertion of the magazine into the razor with cam surfaces formed on the razor so as to be moved thereby and permit movement of the blades out of the magazine.

The principal object of the invention, therefore, is to provide a blade magazine having means formed thereon for releasably confining a stack of blades therein.

A further object of the invention is to provide a blade magazine having means formed thereon and cooperable with a part of the razor for releasing the blades for movement from the magazine.

" the magazine unit comprises a container I0 hav- A further object of the invention is to provide a magazine unit for use with a razor which is simple and inexpensive in construction.

A further object of the invention is to provide a magazine unit having a stack of blades therein and having a novel type of spring means therein claims and may be understood by reference to the accompanying drawings, which by way of illustration show a preferred embodiment of the invention and what I now consider to be the best mode in which I have contemplated applying the principles of my invention. Other embodiments of the invention may be used without departing from the scope of the present invention as set forth in the appended claims.

In the drawings:

Fig. 1 is an enlarged perspective view of the blade magazine embodying this invention;

Fig. 2 is a vertical sectional view of the magazine unit taken along lines 2-2 of Fig. 1;

Fig. 3 is an elevational view of a removable clamp for use with the magazine;

Fig. 4 is a vertical sectional view through a razor with which the magazine unit may be used operative position within ing a stack of blades l2 contained therein and biased upwardly by means of the leaf springs I4. The container I0 is shaped to fit the contour of one of the blades [2 and is provided with a front wall 16, a rear wall 18, and end walls 20. The blades l2 are adapted to fit loosely within the container [0 and are confined between the back wall l8 and a portion 22 of the front wall l6 which is shaped to engage a notch 24 formed in the corners of the blades [2 adjacent the shaving edge 26 thereof. The shaving edge 26 is maintained in spaced relation to the inside of the front wall I6 of the container I0.

The container 10 is preferably made of a spring metal and the end walls 20 thereof are sprung inwardly as shown in Figs. 1 and 2. The springs 14 are arranged in the bottom of the container I0 and are oppositely deflected. Each of the springs is provided with a slit 28 therein and the portions 30 of the springs are fiat and are arranged in abutting relation within the container ID. The portions 32 of the springs are normally deflected into an arcuate shape. The springs 14 are arranged in the container 10 with the flat portions 30 thereof adjacent the front wall 16 of the container ID. The springs [4 are movable vertically within the container ID. The portions 30 of the springs l4 have a loose fit between the vertical walls 33 of the container l0 so as to keep the springs l4 properly located within the container relative to the blades l2 at all times. The walls 33 therefore provide a means for guiding the springs during the vertical movement which occurs whenever a blade is removed from the container in the manner hereinafter described. The springs I4 are placed in the container and the stack of blades I2 is then placed into the container upon the springs M which are compressed thereby.

Each of the end walls 20 at the upper end thereof is provided with an inwardly projecting portion 34 which is adapted to rest upon the adjacent side edge of the top blade inthe stack. The springs i4 bias the blades upwardly against the portions 34 of the end walls 20 so that the blades [2 are confined within the container l against the force of the springs l4. Since the end walls 20 are formed of spring metal, they may be sprung outwardly from the container to permit the blades l2 to be inserted into the container. The end walls 20 are then released and will return to their normal position as shown in Fig. 2 so as to releasably confine the blades within the container l0.

In Fig. 3 there is disclosed a means for ma ntaining the end walls 20 in their normal posit on during handling and shipping of the magazine unit. For this purpose a U-shaped spring wire member 36 is provided, the ends 38 of which are arranged to seat within grooves 40 formed in the upper ends of the end walls 20. The wire 35 may be assembled to the end walls 29 and removed therefrom when it is desired to insert the magazineunit'into the razor with which it -is'us'ed.

The magazine unit disclosed herein is adapted to beused a razor having a chamber therein adapted to receive the magazine unit and having afnieans for successively positioning the blades in the magazine in shaving position on the razor. One'form of razor with which the magazine may be used is disclosed in Figs. 4, 6 and '7. A com plete description of the razor shown in Fig. 4 is disclosed in my oo-pending application Serial No. 160,628, filed May 8, 1950, for Magazine Type Safety'Razor.

The razor comprises in general a body 50'having a chamber 52 therein which is 'adapted to receive the container 10. The body 50 is provided with a blade supporting surface 54 formed thereon adjacent the chamber 52. A slide 56 slidable in a groove58 formed'in a clampingcap 60 is arranged to engage the back edge 62 of the top blade within the stack when the slide is retracted. The slide 56 is then slidable forwardly to move the top blade along the blade supporting surface 54 into shaving position beneath the clamping cap 60. The top blade during its movement into shaving position is arranged to engage the previously positionedblade, as shown inFig. 8, and'to eject the samefrom the razor. A plate 64 issecured to the slide 56. and provides a means for moving the slide across the .chamber .52 in the body 50. A detachable cover .66 is provided for the, lower end of the chamber .152 and has a handle 68 for the razor secured thereto.

When it is desired toinsert a stack of: blade within the razor, the detachable cover (is is removed and the magazine is inserted into the chamber 52. A means, is provided on the razor for engaging the upper ends of theend walls 28 s as to move the. sa e tward y he y leasingthe b ades fo o ementout c t e anber 52; As the container |0 is moved into posifii on, the ends l2 engage-the cam surfaces and are deflected outwardly until they assume the position shown in Fig. 6, at which time theporti ons 34 of the walls have been moved away from the blades l2 so as to permit movement of the. blades upwardly against the underside of theslide'56under the infiuen'ce'of the springs '14.

. fWhen the slide 55 i r etracted. the top blade or the stack is moved upwardly against the under "side 74 of the clamping 'capBOby meansbftfie of said container under spring means.

'4 springs Id. The back edge 62 of the blade is provided with a V-shaped notch 63 which is adapted to be engaged by a V-shaped projection on the forward edge of the slide 56 upon forward movement of the slide 55. Forward movement of the slide 56 moves the blade into shaving position on the blade supporting surface 54 and at the same time is operable for ejecting a previously positioned blade. I The engagement of the projection on the forward edge of the slide with the notch 63 in the blade will centrally locate the blade during movement thereof by the slide onto the surface 54 with respect to the previously positioned blade so that the blades will be aligned as shown in Fig. 8.

The back wall it of the magazine is engageable with the under side M of the clamping cap 69 so as to limit the upward movement of the magazine into the chamber 52 and to properly position the magazinewithin the chamber. A-notch It is'provided in the wall 18 so as to permit the slide 56 to move'across the magazine.

When the last blade in the stack has been used, the handle 58 and the cover '66 are removed from the body 50 and the springs M are then operable for ejecting the container Hi from the chamber 52.

While I have illustrated and'described a preferred embodiment of my invention, it is under stood that this is capable of modification and 'I therefore do not wish to be limited to the precise details set forth but desire to avail myself of such changes and alterations as "fall within the purview of the following claims.
