Jacob Schick of Jersey City, New Jersey, assignor to Magazine Repeating Razor Company, a corporation of New Jersey Razor And Blade Holder Therefor. Application filed April 3, 1924.Serial No. 703,863

This invention relates to an improved safety razor of the type that successively presents blades into shaving position, such type being illustrated in my United States Patent Number 1,452,935, issued April 24, 1923, for safety razors, the present razor being of a simple compact form and requiring but slight effort to operate it to replace one blade by another. The holder and the stack of blades in it form a unit that can be inserted into the razor without the user handling an individual blade either to insert it in the holder or to place it in shaving position. The holder and the blades form an expendable unit so that the purchaser simply inserts the filled holder into the razor and after the blades are used up the holder is thrown away. This not only provides for economy in manufacture and saves time in using the razor, but it also guards against injury as the user need not handle an individual blade at any time.

Furthermore, this package insures a sanitary razor as when the packing of blades in a holder is done automatically the individual blades need not be handled by anyone from the time they are packed until they are used for shaving.

The invention is designed to provide a magazine razor which is constructed so as to be combined with a package of blades which forms a holder, the blades being stacked in the holder and when the holder is inserted in the razor it forms part thereof being in fact the magazine for the blades and being positioned so that the blades can be successively taken from the stack when the razor is manipulated to accomplish such feeding.

The invention also relates to the holder which is adapted for insertion into a razor casing and when so inserted forms the blade magazine.

Another feature of this invention is a spring or other suitable means for forcing the stack of blades so that they can be successively used in the razor, the spring being usually installed in the holder so that the holder when unwrapped and inserted in the razor functions with the moving parts of the razor to manipulate the blades.

The invention is illustrated in the accompanying drawings in which Figure 1 is a top view of a razor made according to my invention and Figure 2 is a vertical section with the stem inside the handle shown in elevation. Figure 3 is a central section at right angles to Figure 2 with the lower part of the handle and the stem shown in elevation. Figure 4 is a section on line 4—4 in Figure 2 and Figure 5 is a perspective view of the casing of the holder. Figure 6 is a similar view showing a shook to cover the casing. Figure 7 is a broken perspective view of one end of the casing of the holder. Figure 8 is an edge view of one of the blades and Figure 9 is a top view of the blade shown in Figure 8.

The razor comprises a guard 10 which is arranged to project from the handle 11 and is of the usual type generally formed with teeth 12 on its edge. A top plate 13 is arranged to slide on the top face of the guard, the opposed faces of the guard and the top plate being usually curved and in close contact to prevent water entering between them except for a recess 14 proportioned to receive a blade 15 with a sharpened edge to project slightly beyond the top plate when in shaving position.

The blade is fed from a stack of blades illustrated at 16. The blade in use is ejected by swinging the top plate forward from the position shown in Figure 2 and a new blade is placed in shaving position by sliding the top plate back in rear of its normal shaving position until it is over the stack of blades and then the shoulder at the back edge of the recess 14 passes over the top blade of the stack and just to the rear of it the top blade is then snapped into position by a pressure means underneath to be hereinafter described. Then when the top blade is slid forward again to shaving position it carries this blade with it and the razor is ready for use.

The means shown for operating the top plate consists of an arm 17 which is pivoted on a pin 18, this pivotal point being the center of the radius of the opposed faces of the top plate and the guard. The arm has an extension 19 which fits in a slot 20 in a collar 21 thus forming a cam on the end of the stem 22 the projecting end 23 of which is beyond the end of the handle and thus available for easy manipulation.

It will be seen from this that when the finger piece 23 is turned the cam groove 20 will actuate the finger 19 and this in turn swings the arm 17 which being secured to the top plate moves the top plate to the desired position. Suitable insignia can be placed on the finger piece or handle to indicate relative positions and directions of operation for placing the blade.

In this razor I use a holder which would be supplied to the purchaser ready for insertion in the razor. In the form shown I place a recess 24 in the guard into which the holder 25 can slide endwise and fits tight enough to hold its position under normal use and when in position it is disposed so that the stack 16 of blades in the holder is in proper position so that its blades can be successively fed from the top as they are needed.

I prefer to make the holder self-contained and for this reason I insert a spring 26 under the stack of blades, this spring having a normal tendency to force the stack of blades upward toward the open side or top of the casing 25 of the holder.

The blades are held in the holder so that they are in alignment, that is the sharpened edges are prevented from engaging or sliding along the wall of the casing. The form illustrated for holding the blades in this way comprises a fin 27 on each end of the casing 25 and each blade 15 has a notch 28 to fit over the fin and when so fitted it can easily slide but each blade is retreated from the wall of the casing so that its sharpened edge is not in contact with the wall. This will be seen from Figure 2.

The holder when sold will be wrapped so that its open side is covered and I prefer to use a shook 29 into which the casing telescopes. This provides for an easy insertion since the casing 25 is projected slightly from the shook its end placed in the recess 24 in the guard and then the casing 25 can be pushed out of the shook and into the casing into the position shown in Figure 3.

The blade holder, it will be noted, is provided with an open side which is usually the top so that if the blade holder is in the razor there is no obstruction to its moving flatwise out of the top of the holder and this movement is only limited by a part of the razor and by no part of the holder. This permits the razor blade to clear the top edge of the holder so that there is no interference with the movement of the blade after it moves vertically out of the holder above the top edge of the holder all around

The spring, it will be noted, is inserted between the bottom of the holder and the bottom blade of the stack so that the spring not only pushes the stack of blades up out of the holder but it also acts to press down on the bottom of the holder so that the holder cannot slide up to have its edges interfere with the movement of the feeding means that sweeps the blade from the top of the stack. This, therefore, insures the clearing necessary between the bottom face of the topmost blade and the top edge of the holder when these parts are in their proper co-operative positions in the razor.

In the preferred form of razor with the curved guard and top plate I prefer to supply the blades curved to the same radius as will be seen in Figures 2 and 8.

The package of blades made according to my invention is light because it is supported and backed up as they are when in shaving position. I find that I do not need blades more than a quarter of an inch wide.

It will be evident that changes can be made in the form and proportion of the parts without departing from the scope of the invention.

I claim:

1. The combination of a razor having means for feeding separate blades successively to shaving position, with a blade holder containing a stack of separate blades and adapted to fit into the razor said holder being readily attachable and when attached being in position to co-operate with the feeding means of the razor.
