A. DUPEYRON SAFETY RAZOR Filed April l, 1931 //s Acorneys l which Patented Jan. 31, 1933 PATENT- OFFICE neuere paranoia, or rams, ramon SAFETY RAZOR Applioaticn iled April 1, 1.931, Serial No. 526,908, and in France April 7, 1830.

The present invention relates to a safety razor of very small dimensions and, therefore, very handy, which, besides the usual advantages presented b all existing safety 5 razors, oiiers the possi ility of using very small and, consequently, `very cheap lades.

The body of the razor, comprising the safety uard, the blade andthe blade presser, is, pre erably mounted ,on a hollow handle',

can `serve as a casing for said razor body, when the razor is not being used, and can also contain spare blades.

The blade is made of thin steel and is consequently flexible; has two cutting edges and is elastically aplied a ainst the guard by means of a sma l bar, w ile it isheld in position on said guard by small projecting parts provided on said guard for engaging notches in the blade.` l

Preferred embodiments of my invention will be hereinafter described with reference to the appended drawing, given merely by wa of example, and in which:

ig. 1 is an elevational view of the razbr; Fig. 2 is an axial cross section thereof; Fi 3 is an horizontal section on line 3-3 of Fig. 1; y

Figs. 4 'and 5 are lane views seen from above of the head of t e'razor only, showing '30 the two positions of the small bar;

Fig. 6 1s a longitudinal section of the razor head, shown at an enlarged scale.

Fig. 7 is a vertical section thereof, on line 7 7, of Fig. 6;

Fig. 8 is a plane view of another embodiment of the razor head;

Fig. 9 is a longitudinal section thereof. (1) designates the hollow handleof the razor, obturated at its lower end by a stop- 40 per (2) and at its upper end by a solid part (3) which is provided with a threaded hole adapted to receive threaded teat (4) inte gral with the blade holder (5) of the razor. The inside of the handle is Preferably pro- 45 vided with a partition (23) which forms two compartments, one for receiving the razor and the other the extra blades shown in (24) (Fig. 3). Teeth (6) are provided in the o posite edges of this blade holder and longltudinally with relation to said blade-,holder so as t0 form guards which prevent cutting while shaving. Blade (7 which has twoedges, comprises a notch at each end, and said notches enga e lugs (8) (Figs. 5 and 6), fixed on the bla e-holder (5), with a view 55 to maintaining blade (7) in the proper position, in the ngitudinal as well as in the lateral direction.

-Said blade is moreover held applied against the blade holder by a small bar (9) 60 o trian ar section whic is articulated to said bla e' holder about an axis (10) comprising two heads (10a) and (10b).

Between Thead (10a) and the base of the blade holder, a spri g (11) is located, which 65 is in compression and consequently tending tostron ly apply small bar (9) against blade holder 5) through (10a). y

At the other end, said bar is downwardly bent at right angles, so as to form an operating lug (12) and is provided with a notch (13), which, when the razor is in use, is engaged under head (14a) of an axis (14) mounted in a similar manner to axis (10) owing to the fact that between the base ofs the blade holder and the lower head (146) a x spring (15) is disposed. The action of the springs (11) and (15) vis exerted upon small bar (9) and consequently upon blade (7) without being hindered by the lugs (8) owin to the fact that bar (9) 1s suitably hollowe out above said lugs, as may be seen from Fig. 6.

Owing to the double sloping or bulging shape of bar (9) and especially owing to the 85 fact that notch (13) is slightly countersunk in (16) Figs. 5 and 6, to constitute a housing for the base of head (14a), when the baris in position for use, as shown in Figs. 4 and 6, said bar is caused to be locked. 9u

According to the embodiment shown. in Figs. 8 and 9 the bar for holding the blade in position consists of a piece (17) suitably cambered, and having sufficient elasticity for applying blade (7 "against blade holder (5). 95

One of the ends of said bar (17 is bent, and re-bent in order to form a projection (18) parallel to the plane of the bar but extending below said bar.

It engages a suiciently large slot (19) prol? i vided in the blade holder (5) and over the centering lugs (8) of the blade, owing to the fact that it is provided with two elongated apertures (20) in which said lugs can slide, when the bar is placed in position.

The other end of that one is downwardly bent at right angles in order to form a lug (21) which engages over a securing teat- (22) integral with blade holder To take the razor to pieces, for instance in order to clean it or to sharpen the blade, it merely suffices to pull the bar (17) towards the right, (Figs. 8 and 9) so as to disengage it fromteat (22) then to cause it to pivot upwardly in order to remove projection (18) from slot (19).

Whatever be the mode of construction that is chosen for the razor, said razor has the advantage of taking up very little room, owing to the possibility of lodging inside the handle the whole of the head of the razor, together with the eXtra blades.

It has also the advantages and all the conveniences for use of the known safety razors, but it is more economical than said razors as, owing to their small size, the razor blades can be sold at a much lower price than any flexible blade now in use.

While I have disclosed what I deem to be the preferred form of my device I do not wish to be limited thereto as there might be changes made in the construction, disposition and form of the parts Without departing from the spirit of my invention as comprehended Within the scope of the appended claims.

It will, of course, beunderstood thatthe razor body above described may be fitted t0 a massive handle as well as to a hollow one.

AWhat I claim is:

1. A safety razor having a narrow flexible blade with two cutting edges, comprising in combination a tubular handle adapted to form a magazine, a partition within said handle, a removable closure at one end of the handle, a solid part at the other end of the handle, a blade holder mounted in a removable manner on said solid part of the handle, teeth made in the two longitudinal edges of said blade holder for forming guards, means for ensuring the correct positioning of the flexible double edged blade on said blade holder, a blade-securing bar pivoted at one end on said blade holder, a spring at the pivoted end of said bar urging the same toward the blade holder, a spring lock at the end of the blade holder opposite the end to which said bar is pivoted, a notch in said bar and a countersunk part in said notch to facilitate the engaging of the lock when said bar is in blade-securing association with the blade holder.

2. In a safety razor having a exible, narrow, double edged blade, the combination of a handle, a blade holder removably mounted on said handle, guard teeth on the two longitudinal edges of said blade holder, means for determining the correct position of the blade on said blade holder, a small bar pivotally associated with one extremity of the blade holder, means including a compression spring adjacent said extremity adapted to press said blade firmly against said blade holder by means of said bar, a knob provided with a shank and disposed at the other extremity of said blade holder, a compression spring on the shank of said knob, a notch in said small bar and a groove in said notch to facilitate engaging the knob when the small bar is pivoted to the position for pressing the blade against the blade holder.

In testimony whereof I afiix my signature.

AUGUSTE DUPEYRON.
