The invention is prin'arily concerned with safety razors of the magazine type.
It is among the objects of the invention to provide a magazine type safety razor of relatively siznple, inexpensive and reliable construction in which the magazine may be incorporated in the structure or assembly of the razor itself, and in. which the need for precision of manufacture is obviated and yet there is assurance of ease and convenience in guiding the blade from the magazine to shaving position without jamming or injury to the cutting edge during such sliding displacement, and there is also obviated the danger of injury from the cutting edge of a blade, both in the charging and during and after ejection thereof.
lAccording to a feature of the invention, the
blade unit is guarded, its longitudinal edges being rounded and confining the cutting edge between and in the plane of said guards, while the razor head has a guide longitudinally thereof, preferably in the form of tracks along the longitudinal edges thereof between which the guarded blade enters with its smooth rounded guard edges guided along the tracks and thereby expelling the used blade therefrom. The r'ela-` tive displacement of the magazine and head after such charge is preferably relied upon to unguard the blade vin the head, that is to displace the cutting edge thereof to shaving posi--y tion outward from the common plane of the guard edges.
According to another feature, the blade magazine is lodged in the handle and longitudinally of the latter and the head has a shank pivoted to a handle extension b ar so that the head .may be brought into alignment with the magazine, the handle having a slide for feeding a blade from the magazine into the handle, the head also having an unguarding slide to engage the main portion of the blade and actuated by a camining connection as the head is pivoted from charging to operative or shaving position.

Fig. 12 isv a perspective View of the guarded blade.
Referring now to the drawings, the razor includes handle I3 and a razor head I-I. Head H has a blade` guide, preferably in the forni of tracks and |5 which may be in the forn of inwardly extending flanges as shown, longitudinally of they upper lateral edge of the downwardly converging fianks of said head.
The blades are of the guarded type shown in my coper'iding application Serial No. 628,081, filed Novemberl 13, 1945, nowV Patent No. 2,561,110, granted July 17, 1951. Desirably theblade proper I6 isy clamped at its backl edge between the reversely bent leavesof a ferrule I'II` each leaf of which ferrule is' of length andl width greater than y The leaves of the` ferrule are provided with a U-shaped cut-out I8 exposing the Cutting edge I 9 of the blade as Well as the end edges 26' thereof. The L I` shape'd cut-out preferably has inturned ends ZI to eX- pose the: ends also ofthe back edge 22 of the cutting blade. vThus the cutting blade is securely cl'amped between the clamping jaws ofthe ferrule, (that is, the portions'framedl by U-sha'ped slot Iii),l which' jai-Ws are desirably bowedas at 23 near their free vedges for resiliency of hold againstl the blade proper It andthe cutting edge I9 is thus normally Ymaintained betw n the later'al edges E@ and'` 25 of the blade unit which are desirably smooth rounded',V as shown, and istherefore guarded withinv the common plane of said guard edges to preclude any possibility of injury.v
, The blade unit, a's best shown in Fig. 5 is securelyretained a't its guard edge'sLZ and125, ref sp`e`ctively,jw ithin the tracks [il` and f5 of the head and isthere shown in guarded" condition'. The head1-I is also" provi ded with an unguarding de: vice best shown inFigs. 2; l and d which, when th'ej d'e`vi`ce is lin operativeposition, dei'ectsthe cuttingfedge I9 outwardto unguarded or shaving p ostion,as'show`n in Figs 2ia'nd`"'=.
W'hile' a blade of the construction set forth 3 may be slid endwise as such or from any suitable magazine, to enter between the tracks I4 and I5 of the head and in such operation may discharge or eject the blade previously in position, and while any suitable device may then be manipulated to deect the cutting edge to unguarded position, and While such arrangement is within the scope of the broader claims herein, I have shown an arrangement in which the magazine is incorporated in a holder, preferably the handle of the razor and in which a relative movement of the handle and the razor head brings the parts to charging position and after charging, the return relative movement of magazine and head brings about the unguarding of the guarded blade.
In one specific embodiment, the razor is of the hoe type and has a T-head H with a unitary shank S pivotally aixed against extension bar 26 of the handle I3 by means of a rivet 21. The proportions of the parts are such that when the head is pivoted to the position shown in Figs. 3 and 8, the face of the head is upright and aligned with the lateral edge of the preferably rectangular handle case I3, so that the outer of the supp-ly of blades B, preferably lodged within a magazine M in the handle case, is aligned with the head.
In a preferred embodiment, the magazine is a rectangular sheet metal trough 28 open at its opposite ends and having inturned flanges 29 at its open face, said trough accommodating the multiplicity of blades B which are pressed outward against the flanges 29 by a leaf spring 33 in the rear face of the magazine reacting against a follower plate 3l and protruding at its bowed middle through a slot 32 in the rear wall of the magazine and reacting against a stop 33 inserted in the handle I3. A U-shaped cover 34 straddles the base of the handle to which it is pivotally affixed by rivet 35, and this affords access for replacement of the magazine when empty.
For charging the razor, the end wall of the handle is provided with a slide 36 straddling the sides of the handle case I3 and provided with a pusher 31 at the inner face of the handle connected to slide 36 by rivet 38, which extends through a slot 39 practically the entire length of the handle case along the end wall thereof, The pusher 31 engages the end edge of the ferrule of the outermost blade in the magazine. Accordingly-the razor is charged by simply pivoting the head to the position shown in Figs. 3 and 8 and thereupon pushing the slide 36, thereby causing the guard edges 24 and 25 of the extreme blade B' to pass from handle case I3 through slot 54 and to enter between the tracks I4 and I5 of the head H and to push out or eject the blade B2 previously therein, until at the end of the movement of slide 36, i. e., when its rivet 38 engages the upper end of slot 39, the fresh blade will be in position.
Thereupon the head H is pivoted back about rivet 21 to its original or shaving position, as shown in Figs. 1, 2 and 4. In this pivoting action, the blade becomes unguarded by the construction now to be described.
The head H desirably includes two distinct flank pieces, each generally T-shaped in form. Flank piece 40 has a shank 4I and a head piece 42 with the inturned track I5. This piece includes an inclined Web 43 narrower than the head, unitary with and connecting the head piece with the shank, and with upstanding end lugs 53.
The companion ank piece 44 has a shank 45 superposed over shank 4I, with the integral head piece 46 with its inturned track I4. The -two shanks in superposed relation are pvotally clamped as at 21 against the bar 26 upstanding from the casing and are co-related to prevent relative rotary displacement with respect to each other in their movement about said rivet, For this purpose, inturned lug 41 on the end of shank 45 ts into a corresponding slot 48 longitudinally of shank 4I and are frictionally held in position of use within depression 49 in upstanding bar 26. The bar 26 has a stud 50 in its face protruding through an L-shaped slot 5I in shank 4I.
Accordingly it will be clear that as the head H is pivoted about its rivet mount 21 from the charging position shown in Figs. 3 and 8 to the operating position shown in Figs. 1 and 2, flank piece 4D will advance longitudinally through a. slide range determined by the L-shaped slot 5I, so that the upstanding lugs 53 on the ends of the web 43 will engage the median part of the blade B and lift it to unguarded or shaving position. Thus, in the movement of the head from charging to shaving position, the cutting edge I9, originally flush with the guarded edges of the blade becomes inclined by tilting it outwardly, as shown, to unguarded position at the proper angle for shaving.
The operation will be clear from the foregoing, but may be briefly summarized. Assuming a new blade B' is to be inserted, the user simply pivots the head H about its pivot 21 to the position shown in Figs. 3 and 8, in which the tracks I4, I5 of the head become aligned with the lateral guards 24, 25 of the extreme blade B in the magazine. Upon now moving the slide 36 upward, the extreme blade B' in the magazine is shifted upward by the pusher 31, as best shown in Fig. 9, to enter at its guarded edges 24, 25 into the tracks I4, I5, respectively, of the head H and to push ahead of it and eject from the head the previously used blade B2, which is of course guarded in its released position, since the flexed blade proper resiliently returns to the plane of the guard edges 24, 25 and so may be discarded without hazard. The slide 36 is stopped by the outer end of slot 39 when the fresh blade has reached its correct position in the head. As the head H is thereupon pivoted back to shaving position, the stud 50 causes the flange piece 40 of the head H, together with track I5, to be pushed upwardly slightly through the coaction of stud 50 with the L-shaped slot 5I in the shank 4I of flank piece 49, the lugs 53 of said flank piece lifting the cutting edge of the blade to unguarded position, and tilting the blade itself, to be inclined upward from its forward edge, as shown. The lugs 41 which have prevented relative rotary displacements between ank pieces 40 and 44 nally snap into depression 49 in bar 26, resiliently to latch the head in shaving position, from which position the head is readily released in recharging with a fresh blade from the magazine in the handle case.
As many changes could be made in the above construction, and many apparently Widely different embodiments of this invention could be made without departing from the scope of the claims, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
