Otto Goetzke, of Jersey City, New Jersey. Safety Razor Application filed October 13, 1930.Serial No. 488,323.

This invention relates to safety razors, particularly to safety razors of the type shown in my former Patent No. 1,751,476, and having a magazine containing a continuous strip of razor blade from which lengths of blade may be fed into operative position and severed.

In razors of this type as heretofore known or described, it has been necessary to pull the length of razor strip from the magazine into position for shaving, This involved the use of complicated winding devices or necessitated a gripping of the sides of the blade with the fingers and thumb and thus provided possibilities of cutting or injuring the hand.

An object of my present invention is to provide a razor having a continuous razor blade strip, and in which the strip may be fed from the magazine without being clutched or pulled; in which the razor blade may be fed or pushed from the magazine by means entirely within the latter; to provide a razor of the above type in which the magazine is effectively sealed against the entrance of moisture and in which the blades fed from the magazine may be readily and quickly severed and removed preparatory to or following shaving.

Another object of the invention is to provide a razor of the above type that is simple, compact and sturdy in construction.

In my present invention a coiled blade strip sufficient in length for several successive blades is contained within a magazine having an outlet in position to deliver to and hinged to the blade guide and holder. Extending within the magazine is a reciprocating element having a strip engaging element so arranged as to engage and grip the strip when the reciprocating element is moved toward the blade outlet and to release this strip when the reciprocating element is drawn to the opposite direction. The outlet is provided with a suitable seal. The blade is delivered through the outlet, slides into the holding means when the latter is swung to open position and, when a sufficient length of blade has been fed, the holder is swung downwardly onto a guard. The length of blade fed through the outlet and received in the holder is bent sharply at the mouth of the holder and severed and held in position. When the holder is again swung to open position this length of blade may be easily removed and, upon operating the reciprocating element, a new length of blade is fed from the magazine.

The various features of the invention are illustrated in the accompanying drawings, in which—

Fig. 1 is a perspective view of a safety razor embodying a preferred form of the invention and showing the razor guide and holder in open position.

Figs. 2 and 3 are, respectively, a front and side elevation of the razor blade holding and guiding elements, being in closed position.

Figs. 4 and 5 are sectional views taken on the lines 4—4 and 5—5 of Figs. 3 and 4, respectively.

Fig. 6 is a detail view of a blade strip engaging and releasing device forming a part of the razor.

Fig. 7 is a detail perspective view of the celluloid plate.

Figs. 8 and 9 are detail sectional views on an enlarged scale of the outlet of the strip from the magazine and showing the blade holding and guiding element in open and closed positions.

Fig. 10 is a detail sectional view of the locking means for the blade holding and guiding means.

Referring to the above drawings a coiled blade strip 11 is contained in a magazine 12 in the razor, a length of strip 13 extending through a fork of the magazine to an outlet opening 15. The magazine 12 may be of any suitable shape. In addition to the fork or branch 14 the magazine is provided with a second branch 16 symmetrically arranged longitudinally to the branch 14 and with a handle extension 17 extending in the opposite direction to that of the branches 14 and 16.

The ends of the branches 14 and 16 and handle 17 are closed except for the outlet 15 in branch 16 and a small opening 18, Fig. 5, in the lower end of the handle 17. The length 13 of blade is drawn from the coil 11 and pushed toward and through the opening 15 by means of a bent reciprocating rod 19 which extends from the handle 17 to a position against the outer wall of the magazine 12 and branch 14 and is provided at its outer end with a strip engaging means which grips the strip when the rod 19 is moved toward the opening 15 and releases the strip when withdrawn in the opposite direction. The strip engaging and releasing means may be of any suitable type.

In the preferred embodiment of the invention shown in the accompanying drawings, the strip engaging means comprises a small box 20 having side walls slightly converging toward the rod 19 and having a small ball 21 which is gripped between the blade 13 and a converging side wall 22 of the box 20 when the rod 19 is pushed upwardly, thereby wedging the blade 13 to the box and the rod 19, and which is drawn loose when the rod 19 moves in the opposite direction, leaving the strip 13 free from engagment. When the rod 19 is moved upwardly again, the ball 21 engages the length 13 in a lower position and carries it upwardly, thus pushing a length of strip outwardly through the opening 15. The lower end of the rod 19 is bent at a right angle to form a flange 23 which fits into grooves in a push rod 24 that extends through the opening 18 in the lower end of the handle 17.

On the lower end of the stem 24 is mounted a sliding open ended box 25 which is held in position by the stem 24, and which is freely slidable lengthwise of the handle 17, the walls of the box 25 being in close sliding engagement with the walls of the handle 17. The rod 19 and stem 24 are resiliently pushed outwardly by means of a coil spring 26 confined between a fixed partition 27 in the upper end of the handle 17 and the flange 23 on the rod 19.

It will be evident that when the box 25 is pushed upwardly and released that the rod 19 will grip the strip 13, push it upwardly toward the outlet 15 and that when the spring 26 returns the rod to position, the strip 13 will be released and not drawn back again into the magazine.

As the strip 13 is pushed out through the outlet 15 it is received between the upper wall 28 of a holder 29, when the latter is in the position shown in Figs. 1 and 8, and a strip 30 secured or pinned to the wall 28 at one edge by suitable means, such as the rivets 31, to hold the blade and to permit the sharpened edge thereof to extend past the front edge of the wall 28. The rear edge of the wall 28 is extended downwardly to form a rear side wall 31a and a holder 29 is pivoted by a pivot pin 32 to a guard 34 that spans the outer ends of the branches 14 and 16.

The holder 29 is mounted at a slightly downward and forward angle to the horizontal or transverse plane of the razor so as to bring it to a suitable position for shaving and to cause the blade 13 automatically to slide into the groove between the holder wall 28 and the strip 30 and to be held therein. The movement of the blade in this groove may be stopped by a suitable stop formed by the wall 28 or strip 30 at the free end of the holder so that when a sufficient length of the strip 13 has been pushed into the holder to form a blade, further movement of the strip is prevented. The holder 29 is also limited in its open position to an inclination less than vertical by means of a downturned end flange 29a so that when opened it is in position to receive the blade strip and guide it into the groove formed therein.

The guard 34 may be secured to the branches 14 and 16 in any suitable manner, preferably by downturned and inturned flanges 35 and 36 which respectively engage the back and front walls of the branches, the inturned flange engaging a suitable horizontal notch or groove near the upper end of the branches 14 and 16. The guard 34 and with it the holder 29 may be removed from the magazine arms 14 and 16 by springing or sliding the flanges 35 and 36 from these grooves or notches.

The guard 34 is provided at its front edge with downwardly and forwardly inclined teeth 37 of usual or any suitable form. The front edge of the upper wall 28 of the holder ends slightly short of the edge of the guard wall 34 so as to expose the blade strip 13, but is provided at its free end with an overlapping finger 38 that snaps over the wall 36 and holds the guide or holder 29 into engagement with the guard 34, as shown in Fig. 10. The finger 38 also serves to hold the blade 13 from sliding forwardly out of its groove in the holder 29. It is so constructed as to wedge the holder 29 tightly onto the guard 34 and to press the holder wall and strip together and thus grip the blade 13 tightly in position. When the holder 29 is swung to open position, this gripping of the blade is released, the groove between the wall 28 and the strip 13 is widened and the blade may, therefore, be easily removed. The finger 38 and a similar finger 38a at the opposite end of the holder 29 also serves to cover the end edges of the severed blade strip and thus protect the face while shaving. The holder may be pushed upwardly against the gripping action of the snap 38 by means of a projection 39 that may be engaged by the thumb.

When a sufficient length of razor strip has thus been pushed through the mouth or opening 15 of the magazine and into the guide and holder 29, the latter is swung about the pivot 32 downwardly onto the guard 34, The opening 15 is extended to a level with the upper surface of the guard 34 so that the blade 13 is bent at a sharp right angle which snaps or severs the blade as indicated in Fig. 9. The severed portion of the blade is then held between the strip 30 and the wall 28 and is compressed therebetween by the gripping of the holder 29 against the upper surface of the guard 34.

The outlet opening is preferably formed by piercing the end of the branch 14 from the inside thus forcing the edges outwardly. This forms a desirable guiding surface on the interior of the opening 15 and a very desirable guiding opening for the strip leaving the magazine.

When the holder is again swung to the open position of Figs. 1 and 8 the used blade length may be withdrawn by a forward pull and the rod 19 reciprocated to advance a new length of blade into the holder. There is, therefore, no necessity of exerting a lengthwise pull on the blade strip and all danger of cutting the fingers is thereby avoided.

The magazine is sealed against the entrance of moisture by means of a rubber strip 40 between the upper end of the branch 14 and a horizontal holding and confining plate 41, Figs. 8 and 9, the rubber strip and the wall 41 being slit in alignment with the opening 15 to permit the passage of the blade. The wall 41 may be supported in the branch 14 by suitable grooves formed therein or in any other suitable manner. The rubber strip not only seals the magazine against the entrance of moisture, but serves to grip the blade and prevent it from slipping backwardly or from re-entering the magazine. Similarly, the opening 18 at the lower end of the handle 17 is sealed by a rubber block 42 confined between the lower end of the handle 17 and a retaining wall 43, Figs. 4 and 5, the block 42 and wall 43 being provided with openings through which the stem 24 passes. The wall 43 may be retained in the handle 17 by horizontal grooves formed in the inner surface of the latter.

To prevent dulling of the edge of the blade by contact with a hard metallic surface, a celluloid plate 44 is provided in the magazine 12 between the strip 11 and the front wall 45 of the magazine. The magazine 12 may be of any suitable form or shape. It is preferably formed of a box portion 44 and a back plate 45. The box portion 44 is provided with a slightly enlarged rim or groove 46 at its rear edge into which the plate 45 is fitted. Suitable packing means are provided in this groove to render the magazine moisture and waterproof. The outer edge of the groove or rim 46 may then be crimped or inturned over the edge of the plate 45, thus preventing the magazine from being opened. The box 44 is slightly narrower at its front than towards its rear in the part of the magazine in which the coil of strip 11 is placed so that the expansive action of the strip 11 serves to thrust the edge of the blade rearwardly and thus keep the front sharpened edge of the blade strip from the front wall of the magazine and from the celluloid plate 24 as much as possible.

Any suitable type of safety razor strip may be employed. To prevent rusting the strip is preferably lacquered.

Any suitable means may also be provided for securing the box 25 to the stem 24. A convenient manner of mounting the box when a hollow stem is employed is to extend the stem through a hole in the box and then peen or turn the edges of the stem outwardly and seal the opening.
