SAFETY RAZOR- Specification of Letters Patent. Patented A Application filed December 15, 1921. Serial No. 522,647.

T 0 all whom it may concern Be it known that I, PAUL J JAooARI), a.

citizen of Switzerland, residing in New York city, 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 full, clear, and exact description.

This invention relates to safety razors, and more specifically to an auxiliary blade therefor having a skin-stretching device, preferably in the form of a bar, for engaging the face in advance of the edge of the cutting-blade thereby facilitating the operation of shaving.

An object of the invention is to provide a simple and practical form of device that can be made economically and may be relied upon in service. Another object of the invention is to provide a form of device which is adapted to fit any of the large number of Gillette, or similar type, razors in use and on the market, without any modification whatever thereof. Also. it aims to provide a device that is capable of being mounted and clamped simultaneously, i. e., in one operation, with the ordinary cutting-blade with which such safety razors are equipped.

These are the objects of my invention and other objects thereof will appear in the following description of the acompanying drawings, illustrating a preferred embodiment of the invention, in which Fig. 1 shows in perspective, and Fig. 2 in side elevation, an assembly of a Gillette type of safety razor equipped with the auxiL' iary blade of the. present invention.

Figs. 3 and 4 are perspective views of modified forms of auxiliary blades, show ing curled edge and roller types, respectively, of skin-stretching bars,

Fig. 5 shows a modified arm by which the bar is supported and the full length of the exposed and available.

Fig. 6 shows an auxiliary blade with a single skin-stretching bar.

In the drawings, the invention is shown applied to a safety razor of the Gillette type, but it is to be understood that it is applicable to numerous varieties of this type of safety razor.

As shown, the razor has a top guard-plate 1 and a bottom guard-plate 2, the latter being equipped with a series of spaced construction more flexibly cutting-blade teeth constituting a comb 3. The top plate trated in Fig. 5, whereby the arms 11 1 on its concave face has a central row of three lugs 1 and the bottom plate 2 a corresponding number of registering holes (not shown) for receiving the lugs. the middle one of which lugs is externally threaded as indicated at l to take an iiiternally threaded part of a handle 4 forclamping the top and bottom plates together more or less uponp flexible cutting-blade 5 having sharp edges 6. So much is old and well-known construction and needs no further disclosure. i

According to my invention, an auxiliary or second blade or plate. adapted to be mounted simultaneously with the cuttingblade, is provided with one or more skinstretching bars supported in advance of the sharp edges of the cutting-blade.

In F igs. 1 and 2, the auxiliary blade, indicated at 7 is shown provided with a central row of holes to pass the lugs 1 and with slots 9 adjacent its edges so as to form skin-stretching bars 10 which are supported at their opposite ends by more or less resilient arms 11 integral with the body portion 12 of the auxiliary blade. The arms may (if desired, but not necessarily) be bent or curved as shown at 13 to clear the sharp edges 6 of the cutting-blade.

The skin-stretching'bar may be in various forms as a plain bar left by punching out the slots, as indicated at 14 in Fig. 6; as a coil or turned edge, indicated at 15 in Fig. 3:01 as a roller 16 journalled at its ends in the arms 11. as ,shown in Fig. 4.

The body portions of the auxiliary blades may be coextensive in length with the cutting-blades, or. of greater length, as illussupporting the bar are left free'and unconfined,

with the result that the skin-stretching bar shown in Fig. 6. substantially to fit the con-- cave face of the top plate.

The auxi iary blades or plates equipped with one or more skin-stretching bars and a central row of holes S-may be mounted at the same time and with the same facility as the cutting-blade between the clamping or guard-plates l and 2., so as to be located slightly in advance of the edge of the cutting'blade. in service, it stretches the skin immediately in advance of the cutting edge and thereby stimulates the action of the lin ers in the operation of shaving;

Being a separate and distinct blade or plate it is optionally usable, and it may be supplied separately or as a part of a complete safety razor equipment. These and other advantages inhere in the construction whose simplicity and practicality is markedly meritorious.

Many changes and alterations may be made in the construction. above described in detail and for a full understanding of the scope of the invention reference is made to the accompanying claims.

Having thus described my invention, what I claim and desire to protect by Letters Patent is: V

l. The combination with a safety razor having a cutting-blade and members for supporting the same with its edge guardedly presented, of an auxiliary blade similarly supported and having means for stretching the skin in advance of the edge of the cutting-blade. I

2. The combination with a safety razor and guardand clamping-members therefor, of an auxiliary blade adapted to be clamped contiguous the cutting-blade and having a skin-stretching bar in advance of the edge of the cutting-blade;

3. The combination with a safety razor having a flexible cutting-blade provided with one or more apertures and guard,

plurality of holes, one or more skin-stretch-- ing bars, and an arm for supporting the bars spaced from the body portion.

6. An auxiliary blade for safety razors having a flexible body portion provided with a longitudinal row of holes for clamping it simultaneously with a flexible cuttingblade one or more skin-stretching bars, and flexible arms for supporting the bars spaced laterally from the body portion.

Signed at New York, New York, this 14th day of December, 1921.
