SAFETY RAZOR Filed August 27, 1925 MM M Patented Jan. 4, 1927.

UNITED STATES I F 1C star SAFETY RAZOR.

Application filed August 27, 1925, Serial No. 52,778, and in Union of South Africa October 10, 1924.

This invention relates to safety razors and in particular consists of a new or improved holder and handle, or device for holding blades of the kind employed in the Gillette and similar types of safety razors, for shaving and also for stropping and/or honing the same. The improved holder and handle can also be used for holding the blades in the stropping and/or honing of the same, preparatory to use in a holder of the Gillette and other similar types of safety razors.

According to this invention the safety razor, or holder in which a safety razor blade can be secured for stropping and/or honing, is constructed to provide a handle portion and a blade holder portion, which portions may be made integral and of metal or other suitable material and of suitable shape and dimensions. Alternatively, the handle portion may be made of any other suitable material and be fixed to the holder portion in any convenient manner.

The holder is constructed along its longitudinal edges with slots forming curved bars, teeth or pro'ections, above the inner ends of which lie the cutting edges of the razor blade, when the latter is in position in the holder.

The portion of the holder on which the razor blade is placed is slightly curved transversely and is provided with pins, tongues or projections with which the blade engages in placing it in the holder to secure it in position therein. One of the pins, tongues or projections is preferably movable and say in the form of an adjustable hookshaped member, and is co-operatively combined with spring means which operate to retain it in engagement with the blade, to secure the latter in position in the holder.

An arched or how spring is provided which is adapted to be placed upon the razor blade and is adapted at both ends to engage with the holder. The spring serves the functions of a further retaining means for the blade and a guard therefor,. and also as a means for bending the edges of the blade slightly in the direction of the inner ends of the slots in the edges of the holder to make it conform, more or less,tothe trans verse curvature of the holder.

The holder is preferably constructed with longitudinal grooves or recesses along the inner ends of the slots to allow the edges of the blade more closely to approach the inner ends of the slots. h

The invention will be more fully described in connection with the accompanying drawings, wherein,

Fig. 1 represents my improved safety razor in plan.

Fig. 2 is a view of the safety razor as seen from the underside.

Fig. 3 is a central longitudinal part-sectional elevation of the safety razor.

Fig. is a transverse section of Fig. 1, drawn to an enlarged scale, the plane of section being indicated by the line mm in Fig. 1, and

Fig. 5 is a side elevation of the arched or how spring (9), detached.

. The combined holder and handle, or device, according to the invention, is construeted to provide a handle or handle portion 1, which may be of the shape shown or any other suitable and preferred form. The handle portion 1 is shown constructed integral with and as an extension or continuation of the holder portion 2 or that portion of the device upon one side of which the safety razor blade 3 is arranged and fixed. The combined handle 1 and holder 2 may be made of any suitable metal and the longtitudinal sides or edges thereof'be bent or curved inwardly on the underside, or on the face opposite to that on which the safety razor blade is fixed, as indicated at t and 5. This imparts to the handle portion 1 a convenient shape for gripping it in the hand, either in the operation of shaving or when stropping. The inwardly bent portions 4, 5, at the sides of the holder portion 2. provide parts in which slots 6 are cut to form the bars, teeth or projections beneath the edges of the blade 3, in a similar manner to existing safety razors.

In the top orupper surface of the portion 2, along the inner edges of the slots 6, longitudinal grooves or recesses 7, 8, areforined which allow the sharpened edges of the razor blade 3 to approach more closely to the up per inner edges of the slots 6 when the blade 3 is additionally secured by means of the arched or bow spring 9, hereinafter referred to, as will be seen more particularly on reference to Fig. 4.

- In the outer end of the holder 2 a recess 10 is formed in the bottom of which a tongue or projection 11 is provided which is bent upwards and formed out of the metal of the holder portion 2. In the end of the holder 2, at either side ofthe recess 19 is formed a small recess 12, and centrally of said portion 2 is formed a longitudinal central slot 13 which is enlarged for a portion of its length, as indicated by the circular arcs 14:, which slot 13 forms the guideway for the other and movable tongue or projection 15. The movable tongue 15 is formed by the overlapping end of a hook-shaped member 16, which is placed at the underside of the combined handle 1 and holder 2, and centrally between the inwardly bent portions 4, 5. of the sides thereof. The overlanping end of the hook-shaped member 16 is somewhat wider than the slot 13 in one end of which it works, so that it is unable to leave said slot 13 in the operation of fixing and dctaching the razor blade 3; the enlargement provided by the arcs 14 allows the enlarged overlapping portion to be placed in sliding engagement with the slot 13 in assembling the parts. The member 16 extends rearwardly and atits rear end has atliized to it a button or projection 17. Around the member 16 between the button or projection 17 and a 7.: stop or projection 1 formed in the underside of the handle portion 1, there is arranged a helical spring 19 wh ch operates to force the hooleshaped extremity of the member 16 in the direction of the rear end of the slot 13.

When the blade is in position, the forward fixed tongue 11 engages in the one hole 20 in the blade 3 and the movable tongue 15 engages in the other hole 21 in said blade, and so acts to retain the blade in its correct relative position centrally between the slot-ted edges of the holder.

22 is a slot in the handle portion 1'for the connection between the button 17 and the member 16 to slide in.

The arched or bow spring 9see also Fig. 5-is fashioned at one end with a hooked cktreinit-y 23, and at the other end with a tail piece 24. When the spring S) is placed in position additionally to secure the blade 3 in. the holder 2, the hooked extremity 23 engages with the end of the holder and the sides of said hooked extremity 23 fit in the recess 12, while the tail piece 24: passes through a slot 25 in the handle portion 1 to the underside thereof. The tail piece 2 1 is preferably shaped or bent, as indicated at 26, which, with the arching of the sprn g, tends to force it tightly against the blade to keep the latter in position with the edges in close proximity to the slotted longitudinal edges of the holder. The sides of the spring 9 are preferably bent slightly downwardly, as indicated at 27, so that it will operate to keep the blade 3 bent to the transverse curvature of the holder 2see F -land it is constructed with two slots 28, 29, to provide clearance between the springt) and tongues 11 and 15, when removing the for- By constructing the handle portion 1 of the device as an extension of the holder portion 2 in a direction parallel to the edges of the razor blade when in po.;ition in the holder, it allows of the device being used for the dual purpose of stropping the edges of the blade and for shaving,

What I claim as my invention and desire to protect by Letters Patent is 1. In safety razors, the combination of a razor blade and a portion upon which said razor blade is detachably fixed, with a handle portion which forms a continuation of the blade holder portion and extends in a direction parallel to the cutting edges of the blade when the latter is in position in the holder, so that it can be used for holding the razor blade for stropping the same and also for shaving, and an arched spring arranged on top of the razor blade and adapted to engage at both ends with the holder to retain said spring in position, as set forth.
