7 Claims. (01. 30-605) This invention relates to improvements in razors and particularly to razors of the safety type in which a relatively thin blade is carried by a blade-supporting member. More specifically, the invention relates to improvements in razors of the type in which is employed a cap member which comprises cooperating sections separately pivoted for transverse or lateral swinging movement from an open, blade-exposing position to a position covering the blade, and which has a carrier or spider member upon which the cap sections are pivotally mounted and which is arranged to be moved, first to cause a closing movement of the cap sections and then to move the cap sections bodily in their closed position to flex the blade and clamp it with a desired degree of pressure for shaving. In the hitherto known razor constructions of this type, the razor handle is provided with a threaded spindle and an operating nut by which the user may shift the spindle longitudinally in the handle and the continuous movement of the spindle in one direction or the other is utilized to move the carrier in the appropriate direction and to bring about the movement of the cap sections to swing the same into their open position for replacing a used blade or removing a blade for purposes of cleaning or the like. Thus one and the same movement is used in the hitherto known constructions for flexing a blade and for exchanging the same, so that the flexing will have to be readjusted each time when a blade has been removed from and reinserted into the razor. This is objectionable because the flexing adjustment requires more time and effort than the exchanging of blades or the like.

Therefore, one object of the present invention is the provision of a razor of the character described which has two independent operating means, one for quickly exchanging the blades, and another for adjusting the flexing of the blade exactly for obtaining the best shaving results. Thus with my new and improved razor construetion, a new blade inserted in place of an old one will be flexed exactly in the same manner as the previous blade without any re-adjustment, and once the flexing has been adjusted properly, it will not be disturbed by the use of the razor for shaving nor by the removal of blades therefrom.

Another object of the present invention is the provision of a razor of the character described which permits an instantaneous swinging of the cap sections into their open position simply by depressing a small lever, and upon releasing said lever the cap sections will swing back auto matically into their closed position and will cause a flexing of the blade exactly as adjusted.

A further object of the present invention is the provision of a razor of the character described which is simple in construction, light in Weight, handy and practical in use, sturdy and durable.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being undersood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

In the accompanying drawing, a preferred form of the invention has been shown.

In said drawing:

Figure 1 is a front elevation of a preferred embodiment of my invention;

Fig. 2 is a side elevation of the same;

Fig. 3 is a sectional view on the line 3-3 of Fig. 2; and,

Fig. 4 is a fractional front elevation of a modification.

Similar reference characters refer to similar parts throughout the several views.

In the drawing the numeral 2 denotes a hollow handle, which has a closed end portion 3 that is provided with a threaded hole. A tubular portion 4 is secured to, or made as a unit with, the open end portion of the handle 2 opposite the end portion 3, and has at least one lateral slot 5 (Fig. 3). To the portion 4 is secured a stationary guard member 6, which has a somewhat convex bladesupporting face provided with fulcrum shoulders over which a razor blade is flexed when clamped in shaving position.

A pair of lug portions '7 are extended from the lower side of the member 6 and have pivoted thereto at 8 a lever ill. The latter has a cam portion l2 which extends through the slot 5 into a slot I 4 of a shaft it, which is slidable in the handle 2 and secured to a carrier IE3. A pair of cap sections H are pivotally mounted upon the carrier l 6 in such a manner that upon forcing of the shaft l5 out of the handle 2 and thus raising the carrier IE, they are swung from the closed position shown in full lines to the open position indicated by dash-and-dotted lines in Fig. 2. The shaft I5 is partially moved out of the handle 2 by depressing the lever l6, so that the cam portion l2 will cause the shaft I 5 to move in a direction opposite to that in which a spring It tends to force the shaft IS. The spring I 8 preferably is a coil spring, as shown, through which a portion of the shaft !5 is extended. 'The main portion of the carrier I5 is shaped as an inverted U to whose web portion is secured the shaft l 5, and to whose flange portions are secured the center portions of cross pieces 19, which are right angularly disposed to the carrier l6. Thus the carrier forms with the cross-pieces IS an I-shaped member, and the cap sections H are pivoted to the ends of those sides of the cross pieces [9 which face the part [5. The cap sections H are similar in shape and are inwardly concave and shaped to flex the blade over the fulcrum shoulders of the guard member 6 when in shaving position.

A nut 20 is screwed upon the threaded lower end portion 22 of the shaft l5, which extends through the spring !8. The latter rests with one end against the nut 20 and with its other end against the member 4, thus tending to force the shaft 15 into the position in which the cap sections H are in their closed position. The guard member 6 has a perforation in its center through which extends the shaft t5, and there are recesses 23 (Fig. 3) in the end portions of the member 6, through which extend the flange portions of the carrier it, so that the cross-pieces it are beneath the member 6 when the carrier 16 is in its lowest position. The lowest points at which the downward travel of the parts 6, l5, l6 and I9 terminates upon releasing the lever II) can be altered by turning a knurled head 24, from which extends a threaded bolt 25 which is screwed through the threaded hole in the lower end portion 3 of the handle 2. The end 2? of the bolt is preferably is increased, so that the bolt 26 cannot be screwed out of the handle 2 entirely. By screwing the bolt is more or less into the handle 2, the shaft it can be moved to a certain extent in a direction opposite to that in which the spring :3 tends to force it, so that the flexing of the razor blade 29 (Fig. 2) can be adjusted. A spring 3| (Fig. 3) preferably is interposed between the end portion 3 of the handle 2 and the head 24, so that there will be sufficient friction for preventing an accidental turning of the

parts

24 and 6 relative to the handle 2.

The cap sections ll have at their outer ends arm portions 31, which extend through recesses in the corner portions of the member 6, and by means of which the cap sections i! are pivoted at 3'3 (Fig. 2) to the cross-pieces [9. The arm portions 3! have at their lower ends outwardly protruding lug sections 35, which engage the member when the parts l5 and it are raised relative to the member 6, so that the cap sections ll will be caused to swing from their closed position shown in full lines to their open position indicated by dash-and-dotted lines in Fig. 2. The web portion of the carrier it extends over a section of the longitudinal center portion of the member and through the slot in the longitudinal center portion of the razor blade 23, so that the carrier it can move up and down without causin a change of the position of the blade 29.

According to the modification of Fig. 4, the member 4 is slotted at opposite sides, and at 28 there are pivoted two levers 3a to opposite portions at the lower side of the member 6. Each lever 36 is provided with a cam portion 32, extending through the slotted portions of the memher 4 into a slot 34 in the shaft [5. The cam portions 32 partially lay one over the other. Thus the raising of the parts l5 and I6 relative to the handle 2 and the member 6- can be carried out either with two fingers of the operator engaging both levers 3%], or with one finger engaging either one of the levers 30.

Since certain changes may be made in the above article and different embodiments of the invention could be made without departing from 4 the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which as a matter of language might be said to fall therebetween.
