RAZOR Filed June l, 1955 Patented Aug. 10, 1937 UNITED STATES PATENT O'F'FIQE RAZOR Application June 1, 1935, Serial No 24,505

12 Claims.

This invention relates to improved razor constructions and particularly to razors of the type having reciprocating saddles eiective to cause the reciprocation of the corresponding razor blades in paths parallel to their cutting edges. A further aspect of the invention relates to an improved type of -blade adapted to be used with a razor of this type. In general, the present invention aiords improvements upon razors of the type disclosed in United States patent to King, No. 1,890,733, particularly providing improved saddle constructions permitting the more ready and inexpensive manufacture of the saddle portions of razors of this type and permitting their convenient assembly with the blades of such razors.

In accordance with this invention, the saddle of a razor may be formed of sheet metal not only being provided with upstanding portions to en- 2 gage the retainer so that the saddle is properly guided in its reciprocatory path, but also preferably having depending sheet metal portions to engage portions of the razor blade. Thus in contrast toI prior arrangements which necessitated the provision of a depending pin associated with the body portion of the saddle, the present invention provides a lug or lugs which preferably are disposed at the ends of the saddle and integral with the sheet metal body portion. These lugs may extend downwardly to engage spaced slots in the razor blade so that the blade is positively engaged by the reciprocable saddle at two spaced points. In accordance with a further development of the invention, the follower pin, which 3 was a feature of previous saddles, may be eliminated and a struck-up integral sheet metal tongue or lug substituted therefor. Thus the entire saddle assembly may be formed of a single piece of sheet metal having upturned extensions 4 and/or ears` slidably engaging the retainer and having depending lugs to engage the blade as well ashaving an upstanding tongue to serve as a cam follower. This construction also permits the shaping of the parallel side portions of the 45 saddle so that it may interfit with the retainer to prevent relative vertical movement of the saddle and retainer in the manner disclosed in my copending application, Serial No. 24,504, filed on even date herewith.

In the accompanying drawing:

Fig. 1 is an enlarged view, partly in elevation and partly in section, showing a razor in which my improved saddle is employed;

Fig. 2 is a sectiony indicated by line 2-2 of Fig.

Fig. `3 is a plan view of the upper part of the razor, showing the retainer swung to its open position.

Figs. 4, 5, 6 and 7 are isometric views of differ'- ent forms of saddles, in which the principles of 5 the present invention are embodied; and

Fig. 8 is an enlarged plan view of a razor blade which may be employed with saddles of the type `disclosed herein.

Referring tothe accompanying drawing which 10 illustrates typical preferred developments of the invention, it is to be noted that the handle I may be connected to the intermediate part of a blade support 2 provided with elongate slots 3 spaced from its edge to separate the body portion from 15 the guard portions 4 of the support. The body portion ofthe support may be provided with a pair of upstanding lugs 5 which are arranged to engage openings in the blade to guide the same in its reciprocating movement, and may have 20 openings 6 to receive the lugs of a saddle. The upper surface of the support may also be provided with small protuberances 'I upon which the blade may rest and slide. The retainer I0 may be connected to one endof the support 2 by a 25 suitable hinge II, while its opposite end is pro vided with a snap clip I2 `which may engage the lower surface of the support 2 to hold the retainer in its normal operative position. When the clip I2 is pressed outwardly and upwardly it snaps 30 past the edge of the support 2 so that the retainer may be swung about the hinge Il to occupy a position substantially in alignment with the support, as shown in Fig. 3.

The retainer I0 may have a pair of integral up- 35 standing ears I5 providing openings in which the ends ofa driving roller I'I may be journaled.. The roller l'l may have corrugated or uted end portions I8 which are adapted to engage the flesh of the user of the razor so that the roller is rotated when the razor is being used. The intermediate part of the roller I1 is provided with a cam groove I9 which may receive a suitable follower 20. `This follower 20 preferably may be an upstanding tongue or lug forming an integral portion of the saddle which is designated generally by the numeral 30.

The saddle 30 (Fig. 4) may comprise a single piece of sheet metal having a generally rectangular body portion with parallel flanges 3| ex- 50 tending along its sides. The ends of these flanges may be provided with extensions 32 which are shaped to provide groove-like recesses interfitting with the sides of an opening I6 (Fig. 3) in the central part of retainer ID. Ears 33 may 55 extend from these flanges and be bent so that they may slidably engage the upper surface of the retainer I0, as shown in Fig. 2. Thus a construction is provided such as is more fully disclosed in my copending application Serial No. 24,504, filed on even date herewith, wherein the sides of the saddle have a slidable interfltting engagement with the retainer so that vertical movement of the saddle relative to the retainer is prevented.

Preferably, as particularly shown in Fig. 4,

the follower or tongue 20 may be of substantially rectangular shape, being formed by cutting a tongue-like part of the body portion of the retainer and bending said part upwardly so that it extends at right angles to the body portion, as shown in Fig. 2, thus leaving an opening 2l in the body portion of the retainer. Between the flanged sides of the retainer integral lugs 35 may be bent downwardly at each of its ends, as particularly shown in Figs. 1 and 4. Preferably the corners of these lugs may be slightly rounded as designated by numeral 36. At eachside of the slots thus left at the ends of the saddle when these lugs are bent down, a part of the body portion of the retainer may be left to cooperate with the ange 3| and its extensions 32 in affording a generally angular reinforcement for this portion of the saddle.

A razor of the type disclosed herein may receive a blade 4U such as is shown in Fig. 8, this blade having spaced openings 4I with parallel side portions 42 arranged to slide at the ends of the lugs 5. Disposed inwardly of the openings 4I the blade may be provided with two relatively narrow rectangular slots 45 extending transversely relativeto the cutting edges of the blade, these slots 45 being positioned to receive the lugs 35.

When a razor of this type is to be used, the blade 40 may be disposed on the lugs 35 of the saddle 3B, the retainer being in the position illustrated in Fig. 3. Thereupon the support 2 may conveniently be swung over into engagement with the retainer so that the lugs 35 extend into opening 6 and so that protuberances 5 are received in the openings 4l in the blade 40. As this movement continues,.the clip I2 snaps past the edge of the support 2 and the parts are in their normal operative position. It is evident that the slots 45 of the blade may t the lugs 35 with only a nominal clearance and that the openings 4| may readily engage lugs 5 irrespective of the position of the saddle 30 on the retainer. Furthermore the lugs 35 are'loosely received in openings 6.

When the parts are thus normally positioned the razor may be used, the corrugated portions I8 of the driving roller l1 engaging the flesh of the user so that the roll is rotated, .thus acting through the carn groove I9 and follower lug 2li in causing a reciprocating movement of the `saddle 30. The lugs 35 of the latter are then effective in causing the blade 40 to reciprocate along a path parallel to its cutting edges, the blade being retained in this path due to the arrangement of the intertting lugs and openings 4|.

Fig. 5 illustrates an optional embodiment of the invention providing a saddle 3l!a with anges 35a and ears 33a similar to those previously described. The saddle, however, may be provided with a cylindrical follower stud 2l)a rather than the follower lug or tongue 20; as also illustrated in Fig. 5, the lower surfaces or edges of the depending lugs 35a may be rounded as designated by numeral 50.

Fig. 6 illustrates another optional type of saddle 33h which may be provided either with a follower in the form of an upstanding integral tongue, as shown in Fig. 4, or may be provided with a follower stud 20h. In accordance with this embodiment of the invention, however, the lugs which engage the transverse slots in the razor blade may be in the form of tongues 35h integral with the sheet metal of the saddle, but struck out of its body portion inwardly of the ends thereof so that openings 59 are provided between the intermediate part of the body portion of the saddle and transverse end rail portions 60 thereof, these transverse portions extending between and reinforcing the parts of the saddle with which the ears 33b are associated.

Fig. '7 illustrates another optional type of saddle 3i]c which is generally similar to those previously described, with the exception of the fact that the ends of the planar body portion of the saddle extend to or slightly beyond the outer ends of the ears 33C as designated by numeral 65,Y the depending lugs 35c which are engageable with the transverse slots of the razor blade being spaced outwardly beyond the ends of the ears.

It is evident that the present invention permits an exceedingly simple and inexpensive form of saddle to be provided for a razor of the type described. Thus, for example, the saddle, together with the cam follower and the projections which engage the blade, may be formed of a single piece of sheet metal or, if desired, the saddle may be provided with a conventional follower pin.
