At 1 ersheet se e lhli-m -gfiflz ffih r w 4 1 sheaths-9i image ventional shape and with longitudinal slots 23 which reduce the weight of the head and provide clearance for the shaving debris. This guard member is formed with a downwardly-extending flange 24 channelled to receive the upstanding channel portion of the plate l6 and permanently connected thereto by a pair of transverse pins or rivets 25. The cap member of the head is similar in shape to the guard member though somewhat narrower. It is provided with a lower substantially flat blade-engaging face and with a downwardly-extending tang 2T rectangular in crosssection and recessed or grooved in one face to receive the wire spring 20 when assembled with the guard member, as shown in Fig. 4. The body of the cap member is provided with a pair of elongated recesses 28 which are ornamental in effect and reduce the weight of this part. It will be understood that the guard member is provided with a centrally disposed rectangular hole which permits the passage of the tang 21 of the cap member with clearance, so that the tang may enter the channel portion IQ of the under plate it and thus be located in position to receive the spring wire 20.
The razor herein shown is intended for use with an open-end blade 30 of thetype shownin Figs. 6 and 14, that is to say a thin generally rectangular blade having a long .slot 3|, opening from one end of the blade and provided with a somewhat wider semi-circular notch 32 in both ends. The slot 3| is of such width asto receive with slight clearance the tang 2? of the cap member so that the blade may be introduced upon the blade seat 22 from one end of the razor and removed therefrom in the opposite direction. For example, with the razor head assembled as suggested in Fig. 6, the blade 30 would be introduced from the right-hand end of the head between the cap and guard members and removed from the same end.
The assembled relation of the parts of. the head is Well shown in Fig. 4 from which it will be seen that the under plate I6 is spaced from the end of the handle l by the upward pressure of the ball l against the slotted lower edge of the plate. The upward pressure of the ball also holds the plate tightly in contact with the closed upper end of the strap [2. This connection permits the head of the razor to be rocked forcibly from one side to the other as suggested in Fig. 5, or to be held yieldingly in central position as suggested in Fig. 2, thus accommodating the user to the most convenient angle for his individual taste. It will be apparent that the ball will yield slightly in suchrocking movement of the head but will hold the head in any selected position without danger of displacement. The construction of the magazine is best shown in Figs. 7-16. It includes in its structurean elongated rectangular shell, preferably of sheet metal but optionally of any other material, having a bottom 40, sides 41 and 42 and top flanges 43 which extend inwardly toward each other but are separated by a substantially open space. This space is widened atone end in a recess 39 designed toreceive with slight clearance one end of the cap member 26 of the razor head. At one end of the magazine the bottom 40 a pair of upstanding lugs or lands 44 which serve as locating areas in cooperation with corresponding faces of the plate It of the razor head, as indicated in Fig. 16. Atthe same end of the magazine the flanges 43 are provided with upstanding lugs 45 for the purpose of pushing a is provided with d used blade out of the razor and also to serve as limit-stops in the path of the feed slide to be presently described.
Within the shell above described is fastened a base plate 46, preferably of plastic material, having a rear wall 4'1 which closes the right-hand end of the magazine as shown in Fig. 8. The opposite end of the magazine is open for reception of the razor head. The base plate is provided with an upstanding median rib 48 upon which is impaled a stack of blades 38. This rib extends at its forward end substantially flush with the plane of the inner faces of the flanges 43 and is provided in its upper edge with a curved recess. It is supplemented by an upstanding stud. d9 shaped to fit the semi-circular recess 32 in the solid ends of the stacked blades and extending slightly above the plane of the inner faces of the flanges 33 so as positively to prevent rearward displacement of the blades in the stack.
At its left end, as shown in Figs. 8 and 12, the base plate is provided with upstanding walls 50 and 5|. The base plate is cut away between these walls and also beneath them as shown in Figs. 15 and 16, so that the two walls are resiliently supported, being spaced from each other so as to receive between them with clearance the channeled rib portion 24 of the guard member of the-razor head. The base plate is positively retained in place by a screw 52 passing through the bottom 40 of the shell and being threaded into the body of the base plate.
The magazine is provided with a feed slide '53 having side flanges which engage the walls 41 and 42 of the shell and an inner blade-engaging plate 54 which is connected to the slide by the stud 55. The latter also acts as a stop to limit the rearward movement of the feed slide by engaging the upper edge of the rear wall 41 of the magazine. The rear wall of the magazine and the base plate itself are slotted to receive a bowed spring 38 which may be inserted after the magazine is loaded and serves yieldingly to support the blade stack and maintain it in contact with the flanges 43.
In bringing the magazine into operative relation with the razor head, the left-hand ends of its inturned flanges 43, as shown in Figs. 7 and 13, are inserted beneath the cap 26 of the razor. The flanges slide inwardly on the flat marginal surfaces at either side of the lands 22, the latter holding the cap in position to clear the flanges. As the magazine is advanced the lugs 45, which project above the level of the blade seat, push the blade 30 out from the left-hand end of the razor head as suggested in Fig. 13. Meanwhile the upper edges of the Walls and 5! engage the lower face of the guard member as shown in Fig. 15. As the magazine is further advanced, its bottom enters one of the slots in the plate Hi and is engaged by the cam surface it. The razor head is moved downwardly with respect to the magazine, as suggested in Fig. 16. In this movement the upper edges of the walls 58 and 5! reach and enter the longitudinal slots 23 of the guard member and as a result of this locating movement, the uppermost blade 30 of the stack in the magazine is brought accurately into alignment with the blade seat as shown in Fig. 16. In this movement the cap 26 may be held upwardly by the underlying blade and always under pressure through the action of the spring 20. The feed slide 53 may now be advanced, engaging the uppermost blade 30 in the stack and sliding it forwardly upon the blade seat 22. The advancing ing of the cap in open end of the blade engages and completes ejection of the used blade, which has already been displaced by the lugs 45, the slot 31 in the fresh blade permitting its passage past the tang 21 of the cap member until the blade is fully seated upon the blade seat in symmetrical position beneath the cap 28-the perfect positionrespect to the guard being attained by the bar 33 located under the cap, which fits snugly in the groove formed between the lands of the guard.
It will be seen that an interlocking connection is formedcby the slots 23 in the guard and the spaced walls 50-5l of the magazine. The latter are formed with upwardly projecting pilot portions which fit into the slots 23. The walls are resiliently supported and are initially depressed by contact with the under face of the guard as shown in Fig. 15. When the magazine has been advanced sufiiciently to register the walls with the slots, the walls are lifted into the slots partly by their own resiliency and partly by the action of the cam I8. The advancing movement of the magazine is limited by engagement of the end of the bottom 40 with the inner end of the cam slot I8.
After a fresh blade has been delivered to the razor the feed slide 53 may be retracted to the position shown in Fig. 13 wherein the stud 55 encounters the rear wall 41 of the magazine. The razor and magazine may now be forcibly separated and in this movement the rounded upper edges of the walls 50 and cams the walls downwardly so that their upper edges may pass out of the slots 23. Meanwhile the spring 20 becomes effective to hold the cap and guard under bladeclamping pressure, being always effective for this purpose.
Having thus disclosed my invention and described in detail illustrative embodiments thereof, I claim as new and desire to secure by Letters Patent:
