Abstract: 208,206. Ginsberg, A. E. Sept. 9, 1922. Razors, safety. In a magazine type of safety razor, a supply of blades is carried in a rotatable holder means being provided for moving a selected blade radiallv outwards into position on a guard and for withdrawing the blade in like manner after use. A cylindrical casing or magazine 1 carried on a handle 12 is closed at one end 15 and fitted with a detachable disc 16 at the other end. Along the front of the casing is formed a slot 2 at each end of which is secured a radial bar 3 with inturned flanges 5 forming a guide groove 4, the outer ends of the bars being joined by a plate 6 with a guard edge and blade stops 7. In use a selected blade is projected through the slot 2 in the casing and is guided by the grooved bars 3 into shaving position on the guard plate 6. The supply of blades is carried in a rotatable holder comprising a sleeve 33 to each end of which is secured a disc 34 formed with radial slots 35 into which the blades 38, with sheet metal backings 39, are dropped. The sleeve 33 is slidably connected by a pin 36 to a central supporting spindle 19 extending from the blind end 15 of the casing and formed externally thereof with a crank handle 20 whereby the holder may be rotated to bring any desired blade into line with the slot 2, indexing means being provided externally of the end 15. The blades are retained in the holder by engagement of the projecting ends of the backings 39 with annular ridges 29 on inner discs 15<a>, 16<a> secured respectively to the end 15 and closure disc 16, gaps being formed opposite the slot 2 in the casing. The discs 15<a>, 16<a> are secured to the ends 15, 16 respectively by spacing bars 24 between which slide members 25 connected to a handle 30. The members 25 are slotted at 26 to straddle the spindle 19 and are formed with inturned solid ends 27 passing through radial slots 28 in the discs 15<a>, 16<a> and formed with transverse grooves 27<a>, Fig. 5, to allow rotation of the blade holder and to engage the projecting backing 39 of any suitably positioned blade when it is required to push this through the slot 2 into the shaving position, Fig. 6. Slidable on the casing, to cover the slot 2 is a curved plate 8 passing the handle by a slot 9 and actuated by a knob 13. The plate 8 is retained in position when the handle is detached, by a nut, 11 on the screwed stud 10. At each end of the cover plate 8 is formed an out-turned strip or tongue 14 which covers the grooves 4 in the guide bars 3 when the plate is moved to cover the slot 2. This may be done after a blade has been moved into shaving position to prevent ingress of soap or water, the ends of the tongues 14 then engaging the back of the blade. The end disc 16 is positioned in the casing end by lugs (not shown) and is locked by a slidable plate 21 thereon formed with a keyhole slot adapted to engage an annular groove in the end of the spindle 19. The slide member 25 cooperating with the disc 16 is connected to the handle 30 by a screwed rod 31 which is partly withdrawn therefrom to enable the disc 16 and connected parts to be removed from the casing and swung on one side without altogether detaching any handle part when it is required to with. draw the blade holder for renewal or replenishment.
