JACOB SCHICK, F NEW YORK, N. Y.

SAFETY nazca.

Application led July 18, 1921. Serial No. 485,840.

To all lwhom it may concern:

Be it known that I, JACOB SGHICK, a citizen of the United States, and a resident of New York, county of New York, and State of New York, have invented certain new and useful Improvements in Safety Razors, of which the following is a specification.

This invention relates to an improved safety razor which is adapted to use what are commonly known as Wafer blades, that is, thin blades, these blades being held within the razor and adapted to be fed therefrom into shaving position when desired, and can be pushed beyond the shaving position for ejection or either to be :replaced by. a new blade or for the purpose of washing the blade and the razor.

rI'he invention is designed to provide a razor or' this kind in which the movement of the magazine can be extended to a point where the magazine is uncovered., whereby a new series of blades can be'inserted in the ma azine. if

e inventionfurther consists in certain details of construction which will be hereinafter more fully described and finally em' bodied in the claims.

- One form of razor embodying my invention is illustrated in the accompanying drawing, in which Figure 1 is a central longitudinal section ithrough the razor. Figure 2 is an elevation or front View of the razor, one-half thereof being shown in central vertical setion. Figure 3 is an end view of the razor. Figure 4c is a horizontal sec- `tion taken on line. 4-4 in Figure 1. Aure 5 is a perspective view of the magazine and guard used in the razor shown in Figures 1, 2 and 3. Figure 6 is a perspective view, broken away to show the form of the positioning plate in the upper end of the andle, and Figure 7 is a perspective view of one of theV blades used in the razor illustrated. l

In the form Shownthehandle 10 has at its upper part a split post .portion 11 and then extends laterally, as at 12, forming arms which are merged into the side plates 13 which support the top late or positioning late 14, this plate eing preferably roun ed to provide a smooth surface for contact with the face of the user. The ma azine 15 is ladapted to swing or slide unerneath the positioning late, this maga zine being box-like,

Figures 1 and 5, withvthe end walls 16,

as wil be seen from the.

front wall 17 and the rear wall 18, and itsshut.

The .front lip 21 of the magazine is provided with teeth 22' so that av guard is formed which has the function of the guard in safety razors, in that it prevents the -blade from cutting the face of the user.l The magazine 15 is mounted on the top of a hollow stem 23 which is preferabl flattened at the sides, as at 24,`so that it ts tightly and makes a good appearance with the split portion of the post l1, the stemhaving an yopening 25 through which the pin 26 is passed, the pin 26 thus acting as a pivotal pin on which the magazine swings, and the of the upper face of the magazine and the lower face of the positioning plate.

I rovide a yielding means 'ed to be successively removed when the shoulder 31 on the under face of the ositioning plate engages the back end o the top-most'blade and is swung forward after such engagement. y

One means of swinging the plate is shown in the drawing, this means including a curved rack `32, the' end of the extension 33 of the stem' 2 3 andapinion 34 rotatablein the handle and adapted 'to be rotated by reason of its being secured vto the stem 35 and the rotating part 36 of the handle,.which, in the form shown, form a chamber into which a package 38 of 'reserve blades can be placed, vand a suitable 4center of which pin is preferably the center l of the arc" which deines the contacting faces for holding', a series of wafer blades that are in the maga-A is hollowed out, as at 37, to

closure 39 is aiiixed to the end to confine the package 38 in the-handle.

In order to 'in-sure a tight Joint hetgeen the upper face of the magazine andthe lower face of the positioning plate, even cessive wear, I provide a yielding means, the

under exform shown comprising a spring encircling the pivotal pin 26 and bearing at its end against the stem 33, the opening 25 being slightly elongated to forin a shortslot to permit a slight upward movement of the magazine, so that there is no limitation to its upward tendency and a tight joint is assured.

Different positions-of the razor parts can be indicated by suitable indicating marks or insignia, shown at 41 in Figure 3.

To hold the blades in alignment I provide suitable aligning'means, in the form shown this comprising convex portions 42 on the side walls 16 ot' the magazine to receive corresponding notches or indentations 43 inV each of the blades 27, and a corresponding enlarged or bulged part 44 at the ends of the recess 45 in the positioning plate permits the movement of the top-most blade into the recess 45 when the bulged part 44 comes in register with the convex portions 42 of the magazine.

The operation of the razor is as follows:

Assuming that the razor is empty and in the position shown in Figure 3, the mechanism for moving the magazine, in this case the rotative part 36 ofthe handle, is turned so that the pinion 34 moves the rack 32 and i* thi-s swings the magazine so that the guard retreats under the positioning plate in other words, the magazine'swin s backward until its top isy opened. A pac age of blades is then placed in the magazine against the pressure of the spring 29 and held downby the finger while the magazine 1s again swung forward to the position sho-wn in Figure 1, the blades now being enclosed in a watertight and air-'tight frame with' no blade exposed.

If a blade is needed, the part 36 is turned and the swinging mechanism as above described is o erated to swing the magazine forward until the 'back end of the top-most blade snaps over the edge of the shoulder 31, then the movement ofthe magazine is reversed and it moves back tothe position shown in Figures'l and 3, but the top-most blade in thel positioning means, that is, in the chamber 45 under the positioning plate 14, i-s held in position, and when the guard on the magazine has been swung back to the pro er point, the razor is ready for shaving. If (esired, this point may be indicated by means of the index 41 shown in Figure 3. In this position the blade is held against retreating and against any longitudinal movement and the guard can be positioned, if desired` to provide for a closer shave.

After the shaving is completed, or if it is necessary to remove the blade, the blade which is in position for shaving can be ejected by swinging the magazine backward until the shoulder 31 appears beyond the end of the guard 22, but not suiliciently to entirely -zine for separatewafer b Lacasse uncover the chamber in the magazine, the blade when thus exposed being adapted to be removed from the chamber or recess 45 and can be cleaned and replaced and the magazine again swung to the position shown in Figure 1. l

It will thus be seen that the razor, when properly operated, will successively remove the blades from the Istack of blades in the magazine, that the device can be operated to eject a blade and be in position to have it replaced therein, so that a blade can be used again in the razor without disturbing the stack of blades in the magazine.

The device is illustrated with the magazine swinging under the positioning plate, but it will be evident that other means and other arrangements of parts can be devised for bringing about the result desired, my invention residing in a razor adapted to successively use blades from a stack of blades, and the invention is designed to include such equivalent motions and mechanisms as will bring about such functioning.
