8 Claims.

This invention relates to safety razors and has for an object to produce a simple and ecient razor which can be made and sold at such a low price that if desired it may have a blade perma- .nently associated' therewith, the whole being thrown away after a single use or as soon as the blade has become dull.

A further object is to so form the razor that it may be dispensed readily from a coin operated dispensing machine and may have associated therewith in a single package a tube of shaving emollient.

A still further object is to so form the razor that the blades may if desired be detachably Yassociated therewith so that all but the blade may be used repeatedly over an extended period. A still further object is to so form the razor that it may be readily manipulated for the presentation of the cutting edge or edges in the most advantageous positions, and particularly in locations diicult or impossible to properly reach with razors as heretofore made.

Further objects and advantageous construc- ,tions will appear from a more complete description of certain embodiments of this invention shown in the accompanying drawings in which Figure 1 is a perspective of a package con sisting of a razor and a tube ofshaving emollient which may be dispensed as a unit;

Figures 14 and 15 are sections through the razor employing the parts shown in Figures 11 and 13 and taken on the section line lli-I4 of Figure 13, the razor being opened and closed respectively.

Figure 16 is an end elevation showing the razor closed as in FigureV 15.`

The razor comprises a handle and a guard or support for a razor blade which consists of a plate member I having a portion intermediate its ends as at 2 curved to form a blade support. At

each side of the curved portion 2 the plate ends 15V are bent sharply toward each other at the concave face of the portions 2 as at 3 to form inwardly curving portions 4, the ends of which are then turned outwardly away from each other as at 5 sufficiently close to the guard to present 20 their substantiallyparallel end edges convenient for engagement by the fingers of the user. To this end they should not be spaced from the guard by a distance substantially greater than the width of the guard and as shown they are 25 spaced slightly less than this distance. These handle edges are also substantially parallel to the cutting edge or edges of the razor blade. By manipulation between the lingers the razor may be presented at any desired angular position with- 30 in a wide range without changing the angular position of the hand, the inwardly concaved portions 4 forming depressions affording space to receive the ends of the fingers, particularly in the extreme rocked positions of the razor. Preferably the edges of these end portions have recesses or indentations 6 therein which form dinger holds to facilitate grasping the razor. The bent portions 3 are preferably slotted laterally at intervals to permit the passage of lather and 4.0 hair portions.

As shown in Figures 1, 2 and 3 the razor blade at 9 may 'be permanently secured against the convex outer face of the portion 2. To this end a clamping element i is placed over the outer face of the blade and the blade clamping element and guard portion 2 are permanently secured together as by the tubular rivets B which are passed through the end holes of the blade, double edge blades as made commercially being provided with such holes.. This form of the razor where the Yblade is permanently fixed is particularly suitable for dispensing from a coin operated dispensing machine and such machines may be conveniently provided in wash rooms of railroad cars,

hotels, or the like, so as to be convenient for a traveler who may Wish to use the razor a single time and then discard it, or if desired he may use it as long as the blade remains in good condition. When the razor is to be dispensed in this manner the formation of the handle adapts it admirably to have packaged with the razor a suitable receptacle such as a collapsible tube indicated at ||l in Figure 1 which may contain a shaving emollient. This may be held frictionally between the portions 4 of the razor and may be removed by the purchaser for use as desired. This tube, as shown in Figure l, may be provided with the usual screw cap I which may beremoved by the user and the contents of the tube may then be squeezed out by collapsing the tube.

The razor may be made up in forms which permit the detachment of a razor blade for the insertion of a new blade when desired and certain constructions to this end are shown in Figures 4 'to 10. Referring rst to Figures 4, 5 and 6, the razor supporting portion 2U, instead of being provided With holes for the reception of rivets is provided with inwardly offset tongues 2| with which'may cooperate similarly inclined tongues 22 of the clamping member 23 which may be projected through the holes 24 of the razor blade and engaged beneath the tongues 2|. The clamping member 23 is shaped in general similarly to the clamping element Tshownin Figures land 3. By moving the handle member and clamping element relatively laterally of the direction of curvature of the blade supporting portion 20 the blade may be clamped or released from its position. The portions 2| and 22 which form cooperating wedge elements are shownvas arranged to an angle of about 14 and 30 from the transverse axis of the portion 20, this being yfound in actual practice to prevent accidental detachment of the parts and yet permit them to be moved readily to'clamp or release the blade whenever desired, and by forming the roots of the portion 22 oppositely curved with their concavities facing each other as shown in Figure 6, they will properly cooperate Witheither round holes or straight edge faces of the blade 6 holding'thern against lateral motion. If desired, one or both portions 22 may have a projection 25 formed to snap into a hole 26 in the portion 2| when the blade is in changed position to prevent accidental disengagement of the parts. The clamping member may, if desired, be provided with a central depression 21 which stiffens it and facilitates moving the member with the fingers. The blades Iare formed initially flat and the bending thereof produced by the relative sliding of the handle member and clamping element holds these parts under frictional engagement and prevents theparts from too ready detachment while permitting suiiicient bending of the blade to bring it down tight against the convex face of the portion 20 when desired. The amount of relative motion furnishes a means for adjusting the curvature of the blade and thus the closeness of the shave.

In Figures 7 to 10a still further modiilcation is shown in which the handle member isformed with spaced holes 30 corresponding to the spacing of the holes in the blade and the clamping element 3| is provided with posts 32 which maybe passed through the blade holes and the holes 30 of the handle member. These posts32-.are formed with heads 34 provided with inclined upper faces 35 with which cooperate inclined wing elements y36 of a clamp retaining element31. This element hole 39 through which each of the posts 32 may be passed and then by an axial movement of the member 3'| the wings 36 may be drawn into engagement with the faces 35 of the element 3| drawn down against the blade to clamp it against 5 the convex face of the blade supporting portion of the handle. The member 31 may be provided With a down turned handle portion 4D by which it may-be grasped. By anainspection'of AFigures 3 and 5, it may be seen that a cross section 10 through the razor transverse to the cutting edges rof, the blade and through the handle presents an exterior outline which may be inscribed in a substantially rectangular or square gure, the out-turned end edges of the handle lying sub- 15 stantially in adjacent corners of the figure and the blade being substantially parallel to one side of the figure.

insertion 0r removal of blades .may-be facilitated 30.
