- 'ments in Razors, of which the following is a specification, reference being had therein the accompanying drawing.
This invention relates to safety razors, the
blade of which has an edge oblique to thelongitudinal axis 0r oblique converging edges, and consists in the blade being so connected with its holder or the protecting part respectively, that it can be moved longitudinally into position for efi'ective work or the blade can easily be cleaned, sharpened or stropped. In the position of the blade last mentioned, theapplia'nce may be -used also as an ordi-nary razor, even if it is construct-j ed like-a safety razor,
In the accompanying drawing some forms of the invention are shown as examples.
Figure 11$ 2. side view of a safety razor.
Fig. 2 is a plan view of the bladholder or guard and the bladeand a part of the han dle. Figs. 3, 4,5, and 6 are cross sections'of the "holder and the-blade on the section line A-'-A of Fig. 2and show different shapes of the said section. Figs. 3 to 6 inclusively are drawn on a greater scale. Fig. 7 is a stiflt' plate and preferably integral with the.
5 cross section of a blade adapted to the holder shown in Figs. 1 and 2. Figs. 8, '9 and 12, 13, are side views and plan views respectively of blades, adapted to the holder shown in Figs. 1 and 2 but provided withotherconnecting means than thosejshown in Figs. 3 to ,7 inclusive. Fig. 10 is a plan view of a modified holder, Fig. 11 is a section of the said holder and a blade, belonging to the same, on the sectionline BB of Fig. 10. Fi% 14= shows two other shapes of the guard. g. 15 is aplan View showing a modification of the blade, and its holder. 7
The holder 1, called the guard in a safety razor (Figs. 1, 2, and 10), which is made of handle 2, is provided at its edges with teeth 3 which, in the well known manner, have a protecting'action during the. shaving operation. The blade 4 has one of its flat sides directed toward the holder 1 and is so 0011- sharp.
? "nected the same, that it can be moved longitudinally to the holder. The said blade has two converging edges5. The rim of the narrower end of the blade, which rim is semicircular or has any other similar shape, may also form a sharpened edge, it wanted. The two rows in thes'ame or substantially the same degree as the edges 5 and may be connected by a semicircular or similar row of teeth, as shown in the drawing. The said teeth may of protecting teeth 3 converge l be perpendicular or substantially perpendicular to the-longitudinal axis of the holder, as shownin Fig. 15,.so that they have'an oblique position with relation tothe edges, and consequently catch the bristles during the shavin V then out '0 at acute angles, the shaving operation being thus-rendered agreeable and painless even if the edge is not perfectly operation, whichbristles are 1 In the safety razor shown in Figs. 1 and 2, the 'holder 1s arranged to hold the movable blade by means of a stiffening part, ex-
tending longitudinally of the blade, an enlarged ridge 6 (Figs. 3 to 7 inclusively and Fi s. 12 and13) or a row of vitIed with heads or buttons 7 Figs. -8 and 9). Thesaidridge is fixed to the blade in any suitable manner. For instance it may be riveted to the blade, as shown in Fig. 5. Theridge may be made integral with the blade, by shaping the blade as shown in Figs, 6 and 7. In Figs. 12 and 13 the ridge 6 is connected with the blade in a detachable manner by means of angular'to-ngue shaped pieces 8, provided on the ridge 6. The said pieces are passed through corresponding openings 9 in the blade, the ridge and blade being then moved with re'lat1on to each other.
pins 11 pro- "The holder shown in Figs. 1 and proshowniin dotted lines ,in Fig. 2, in which posit-i015, thejblade is held so firmly, that it can be cleaned,'sharpened or stropped. For ad ditional security the tongue shaped pleces a: and y on each side of the said slot 10 (Ficg.
2) may be so arranged, that they bear yiel ingly against the sides of the ridge. As the edges of the blade, moved to the position last mentioned, are perfectly free from the protecting teeth 3, the appliance may in this position of the blade be used as an ordinary razor. safety razor, the distance between the edges 5 and the free ends of the protecting teeth 3 can be changed, by moving the blade for a short distance from the position shown in full lines in Fig. 2, and the razor thus be adapted to the sensibility of the skin and to coarser-or finer shaving respectively. For the said purpose a scale may be provided. as for instance in the holder, as shown in Fig. 2, in which three lines are shown, the inner end of the ridge 6 forming the index cooperating with the said lines.
v The razor may be provided with a device to keep the blade in its different positions with relation to the holder, without, however, preventing the blade from being re-- moved from the holder, when wanted. The
has a central tongue shaped piece 12, at
the sides of which slots 13 are provided. A central longitudinal portion 14 of the blade is raised, the said raised portion being U- shaped in cross section and embracing the said tongue 12, when the blade is mounted in the holder, as shown in Fig. 11, thus keeping the blade in its holder. Also in this form of the invention the blade can be mounted in different positions in the holder, as described above with reference to Fig. 2.
In Figs. 8 and '9 a raised portion 15 of .the blade is substituted for the stiffening part or ridge mentioned above, the pins 11 with the buttons 7 being fixed in the said raised portion. 1
The shape of the cross section of the holder may bevaried'in many ways. It may be straight as shown in Figs. 3'and 11, or curve shaped as shown in Fig. 4. The holders shown in cross sections in Figs. 5 and 6, have a plane and curve-shaped central part respectively, while each of the rims (including the protecting teeth) are first bent away from the blade and then towardthe same and the edges of the blade respectively.
Fig. 14 shows a modification of the protecting device, consisting in a corrugated or wrinkled edge being substituted for the rowof protecting teeth. The edge of the blade-cooperates with the said corrugated edge in the same manner as with the row of protecting teeth.
When the appliance isused as'a' pleasure.
The invention may evidently be modified in many respects without departing from its essential features. As for instance, 1nstead of two edges only one edge may be provided on the blade 4, as shown in Fig. 15, which edge converges to the longitudinal axis of the blade, the guard being correspondingly shaped or substantially so. The blade 4 is shown in operating position by full lines, and in position to be stropped or cleaned by dotted lines.
