SAFETY-RAZOR.

Specification of Letters Patent.

Patented July 20, 1915.

Application led October 12, 1912. Serial No. 725,461.

To all 'whom it may concern Be it known that I, HENRY J. GAISMAN, a citizen of the United States, and resident of New York city, borough of Manhattan, in the 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.

. The object of my invention is to provide a safety razor wherein the blade and guard may be readily moved in and out of shaving relation one to another, and be retained in such positions, and whereby the blade edge may be held'in position to enable its opp0- site sides to be drawn along a strop for sharpening the blade edge while the guard is retained in position not to interfere with the strop.

A further object of my invention is to provide a razor guard with spaced adjacent lugs for the blade edge, whereby the guard may be retained firmly in different set positions with respectl to the blade edge, to enable shaves of different character to be readily obtained.

My invention also comprises novel details of improvement and combinations of parts more fully `hereinafter s et forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings forming part hereof, wherein,

Figure l is a rear view of a safety razor embodying my invention, showing the guardl and blade separated; Fig. 2 is a section on the

line

2, 2, in Fig. l; Fig. 3 is a front view, illustrating the guard andblade in shaving position; Fig.4 is a section on the

line

4, 4, in Fig. 3; Fig. 5 is an enlarged section on the

line

5, 5, in Fig. 3, showing the guard and blade in a different position from Fig. 3; Fig. 6 is a section on the

line

6, 6, in Fig. 5, and Fig. 7 is a perspective View of a portion of one of the springs.

Similar numerals. of reference indicate corresponding parts in the several views.

The numeral l indicates a frameof any suitable construction, shown in substantially U-shaped form having a base portion la and spaced side members 1b, and 2 indicates a handle of any suitable construction secured to said holder or frame.

3 indicates a guard which may be generally of any well known construction provided with guard teeth, the guard being shown pivotally supported at 4 by pivots journaled in suitable openings in the side members lb of the frame. The guard shown is adapted to swing within the space between the members la, lb.. Said guard is shown provided at its lfront corners with lugs or'hooks 3a to engage the edge of the blade 5, and said guard is also shown provided'with lugs 3b at its sides, respectively adjacent to and spaced from the lugs 3, to engage the blade edge, the lugs 3b being shown slightly lnearer the pivots 4 than the lugs 3a, whereby the relation of the .blade edge to the guard teeth may be varied according to which set of lugs 3a or 3b the blade edge engages to provide for shaves of different character.

The guard at its inner portion is adapted to bear against a spring 6, carried 'by the frame, and said` guard, on the side of the pivots 4 opposite the comb teeth, is shown provided with bearing surfaces to engage spring 6, said surfaces being shown in 'the form of flat faces 3c, 3d, whereby the tension of spring 6 serves to retain the guard inthe shaving position shown in Figs. 4 and 5, and out of such position as shown in Fig. 2. Blade 5 is detaohably carried by a blade holder 7 of any suitable construction carried upon-'shaft or pivots 8 journaled on frame Al-,whereby the blade may swing or rock in the holder. At 9 is a spring carried by frame or holder 1, adapted to bear against blade holder 7 to retain the latter and blade 5 in shaving position with re spect to the guard, as shown in Figs. 4 and 5, and out of such position as shown in Fig. 2. Holder 7 is shown provided with bearing surfaces 7a, 7", spaced apart in suitable relation, to engage spring 9 and retain the blade and its holder in different positions shown in Figs. 2 and 5. The

springs

6, 9, are shown located between the guard and the blade holder, in the space between members l", and said springs are shown provided at their ends with projections 10,' located in grooves ll in the inner faces of members lb of the frame, whereby said springs are guided upon frame or holder l and are permitted to have free movement at their ends. In the example illustrated, the springs G, 9,

. are bent outwardly or oppositely at 12, to

bear against the guard and blade holder respectively, and are bent toward each other substantially in the central position. as shown at 13, where they may bear against .thereby and spaced apart, and

the fingers near the blade edge, l have shown the guard and blade holder as respectively provided with

extensions

14 and 15, projecting outwardly at the rear of the razor, in position to be engaged by the fingers, said

projections

14, 15 being shown located close together and adapted to pass freely, where* by when the blade and guard are separated,` 15, as shown in Fig. 2, and it is desired to close the blade upon the guard, the

projections

14 and 15 may be pressed apart, to swing the guard and blade holder .into the positions shown in Fig. 5, and when it is desired to separate the guard and blade, the projec-

` tions

14, 15 may be operated to swing the guard and blade away from each other.

The guard is extensions 16 by which the guard may be operated by the finger when desired.

In accordance with my improvements, the guard and blade may be readilv brought into shaving relation by swinging one' or both toward the other, and the spring tension against the guard or blade holder will retain them with the appropriate lugs of the guard bearing against the blade edge. When it is desired to insert or `remove a blade or clean the parts, the blade holder may be swung to the position shown in Fig. 2, with or without moving the guard. When it is desired to strop the blade edge, the blade may be placed in the position shown in Fig. 2, and its edge drawn along the strop, turning one side and the other against the strop as desired, the spring 9 bearing against the blade holder retaining the blade in proper position.

Changes may be made in the detailsof construction and arrangements. of parts shown and described, within the scope of the appended claims, without departing from the spirit ofthe invention. .j
