COMPLETE SPECIFICATION. Improvements in Safety Razors

264,203

I, Jacob Schick, a citizen of the United States of America, of 78, Harrison Street, East Orange, County of Essex, State of New Jersey, United States of America, do hereby declare the nature of this invention and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement:—

This invention relates to magazine safety razors of the kind which contain a stack of wafer blades which are fed from the stack successively into the guard, which thus permits the easy replacement of a dull blade by a sharp one.

The invention consists in a safety razor of the kind described comprising a handle, a guard mounted on said handle, a recess in said handle adapted to receive a plurality of blades in stack relation, and resilient means arranged in said recess and acting to move said blades into position to be engaged by means acting positively to place a blade in operative position in said guard.

The invention further consists in a safety razor as described in the preceding paragraph in which the blades are held in stacked relation in a blade holder positioned within a member longitudinally removable from and insertable in the handle of the razor, said holder being provided with spring means acting (when the holder is in position within the handle of the razor) to press the blades toward the other side thereof and into position to be fed into operative position.

The invention further consists in a safety razor of the kind described in which the blades are maintained in stacked relation in a recess beneath a movable top plate, means being provided to cause said top plate to slide to and fro over said recess and thereby eject a used blade and position a new blade in operative position, the handle of the razor being provided with a rotatable stem provided with a cam to actuate a pivoted arm connected to said top plate to cause the desired motion of said plate when said stem is rotated.

Further features of the invention will hereinafter appear and be specifically pointed out in the appended claims.

The invention is illustrated in the accompanying drawings in which—

In the drawings:

The handle 10 has the guard 11 pivoted to the post 12, the guard being slotted at 13 so that it can be swung either into the longitudinal position shown in full line in Fig. 2, or into the laterally extending shaving position shown in dotted lines. The curved front edge 15 and the face 16 flank the blade 18 which fits the slit 17, the blade being inserted endwise into the slit and being frictionally held by spring 19 which bears lightly on the blade.

When the guard 11 is swung into the lateral shaving position the spring is engaged by the cam end 20 of post 12 which presses the spring 19 and blade 18 so as to hold the blade against sliding. The blades are carried in the handle which has a recess 21 to receive the stack of blades.

In the form shown, the stack of blades is held in a holder 22 comprising an open-sided frame with a spring 23 to bear on the underside of the stack of blades. The holder is carried by a stem 24 which extends into recess 21 and has a head 25 swivelled thereon, as by means of the disc 26 fitting in recess 27, which head screws onto the end of the handle.

For feeding the blades from the stack to the guard, I provide a sleeve 28 sliding on the handle and carrying a trigger 29 having a rounded outer face 30 fastened against the inside of the sleeve by screw 31. The faces 32 of the trigger slide on faces 33 of the flat part of the handle alongside slot 34 in which the trigger slides. The projection 35 of the trigger is arranged when the slide is pulled back to just catch over the topmost blade of the stack, as in Figure 2, and to pick up one blade and slide it forward when the sleeve 28 is pushed forward.

The blade is thus passed through a slit 36 in the end of the handle and into the slit 17 in the guard, the sleeve being halted when the trigger engages the end 37 of the slot 34 and the projection 35 reaches the end of the slit 36, and as the edge of the guard and the end of the handle are coincidental, the blade is entirely within the guard. The guard, when so supplied, can be swung to the position shown in outline in Figure 2, or any intermediate tilted position in the device, for shaving.

When a new blade is desired, the guard is swung back into longitudinal position and the sleeve is again operated to feed a blade into the guard, this blade ejecting the old blade. The flap 39 held by a light spring 40 closes the slit 36 and prevents water entering the handle.

I place the blades in a clip preferably made as shown at 41 with the side wall 42, end walls 43 and an open bottom through which the spring 23 can project. Flanges 44 at the bottom support the blades along their ends, flanges not shown hold the blades at the corners, of their sharpened edges so that the blades are fed through without any injury to the cutting edges.

The clips 41 are preferably wrapped when sold to the user and when the wrapper is removed the clip can be inserted between the ends 46 and 47 of the holder 22. This provides for the clip and the holder being slid into the handle together and the clip is prevented from projecting into the path of the top blade by the shoulders 48. (See Figure 6).

The edge 49 of the handle receives the bottom edge of the cap 50 which encloses the guard, and provides a neat, symmetrical razor. The post 12 is slightly tilted on the top of the handle so that when the guard is swung to shaving position the blade 18 is inclined at the proper shaving angle.

The form illustrated in Figures 9 to 14 is designed to feed the blades frontwise instead of edgewise and consists of a guard 51 arranged on the handle 52 and is of the usual type with the teeth 53 on its front edge. A top plate 54 slides on the top face of the guard, the faces being curved and in close contact except for the recess 55 proportioned to receive a blade 18.

In the form of razor shown in Figures 9 to 14 the blade is fed from a stack as in the construction shown in Figures 1 to 8, the stack being shown at 56, and a new blade is placed in shaving position by sliding the top plate to the rear of its normal shaving position and when the shoulder formed on the top plate at the back edge of the recess 55 passes over the top blade of the stack, the top blade is snapped into position by a pressure means underneath such as the spring 57. The spring 57 is placed within the holder 58, the holder, when divested of its outer wrapping or other covering, being placed in the recess 60 and being slid endwise therein.

Various means for operating the top plate can be devised and I show an arm 61 pivoted on a pin 62 with an extension 63 which fits in a slot 64 in a collar 65. This forms a cam on the end of a stem 66, the projecting end 67 of which is beyond the end of the handle and thus available for easy manipulation.

The blades are held in the holder so that the sharpened edges are prevented from engaging the wall of the casing and in the form shown each blade has notches 69 to fit over the fins 68 on the holder.

Having now particularly described and ascertained the nature, of my said invention and in what manner the same is to be performed, I declare that, what I claim is:—

1. A safety razor of the kind described comprising a handle, a guard mounted on said handle, a recess in said handle adapted to receive a plurality of blades in stacked relation, and resilient means arranged in said recess and acting to move said blades into position to be engaged by means acting positively to place a blade in operative position in said guard.
