l This invention relates to improvements in safety razors.

One of the important features of the invention resides in quick and simple means of releasably securing the clamping member and guard member together with a conventional razor blade interposed therebetween.

Another feature of the invention is .to provide a safety razor having a reversible handle by which the razor may either be used in a manner wherein the handle extends from beneath the head, or from one end of the head for use in the manner of a straight razor.

Other features of the invention will become apparent as the following specification is read in conjunction with the accompanying drawing in which,

Figure 1 is a perspective view of a safety razor constructed in accordance with my invention.

Figure 2 is a perspective view of the safety razor shown in Figure 1 but with the parts in separated relation.

Figure 3 is an enlarged horizontal sectional view on the line 3-3 of Figure 1.

Figure 4 is a vertical transverse sectional view on the line 44 of Figure 3.

Referring to the drawing by reference characters and at present to Figures 1 to 4 thereof, .the numeral I designates a safety razor constructed in accordance with my invention. The razor ID includes a guard member H, and a clamping member or cap I2 between which a double edge blade I 3 is securely clamped in flexed position by a novel separable connecting means presently to be described. The members II and I2 are preferably made of metal but they may be made of plastic material if desired.

The guard member ll comprises a, rectangular shaped body I 4 having rearwardly ofiset guard edges I5-|5. Elongated slots Iii-l6 parallel the guard edges I5l5. The body I4 is provided with a'centrally located elongated slot I! and with a pair of blade positioning lugs l8l3 respectively disposed beyond the ends of the slot l1. Integral with one end of the body I 4 of the guard member is a straight hollow handle Hi, the front side of which is flush with and parallel to the front face of the body I, so that the thickness of the handle extends rearwardly beyond the plane of the rear face of said body. The handle I9 is shown as being square in cross section and open at its inner end. Slidable within the open end of the handle I9 is a latch element 20, the same being square in cross section while (the outer end is bifurcated as at 2|, the urea-- 2 Claims. (01. 30-55) cation. The rear wall tions of which are respectively disposed beyond the plane of the opposite longitudinal edges of the slot IT. The f'urcationsareconnected' by a length less than the bifurof the handle is provided with an elongated slot 23 through which a manipulating element 24 extends, said element being fixedly secured to the slidable latch element 20. Sliding movement of the latch element 20 is limited in opposite directions by engagement of the manipulating element 24 with opposite ends of the slot 23.

The blade clamping member or cap l2 has a lug 25 extending centrally from the inner side thereof which is of a thickness and width to freely pass through the slot [1. Extending inwardly from one side edge of the lug 25 is a keeper notch 26, the same being of a width to tightly receive the tongue 22. If desired, the wall 21 of the notch 26 may be slightly inclined to enable the tongue to wedgingly engage the same for reasons to be hereafter appreciated. The inner side of the clamping member I2 is provided with recesses 28-28 which are complementary to the positioning lugs l8-l8 to receive the same when the members II and I2 are clamped together with the blade |3 interposed therebetween.

The blade I3 is a conventional double edge blade having positioning lug receiving slots 29 therein.

In practice, assume that the parts of the razor II] are in separated condition as shown in Figure 2. To assemble the parts for use of the razor, the blade I3 is placed flat against the front side of the guard member body M with the positioning lugs l8l8 passing through the slots 29. The inner side of the clamping member I2 is now applied against the seated blade l3 and the lug 25 thereof is freely inserted through the slot 29 in the blade and through the slot I"! in the guard body l4. The latching element which is shown in Figure 2 as being in retracted position is now slid outwardly by pressing the finger against the manipulating element 24, whereupon the furca- .tions of the bifurcation 2| are slid into embracing engagement with opposite flat sides of the lug 25 while the tongue 22 tightly enters the keeper notch 26. This latching action causes the members II and I2 to be drawn into tight clamping relation sufficient to flex the blade l3 and hold the same in rigid position for shaving purposes. When using the razor for shaving the same is held and manipulated in the manner of a conlatching tongue 22 of a ventional straight razor. The clamping member l2, guard member H and blade l3 may be separated for cleaning purposes by pushing upon the manipulating element 24 to slide the latch element to retracted position, whereupon the tongue 22 will become disengaged from the keeper slot 26 of thelug 25.

While Ihave shown and described what I consider to be the preferred embodiment of my invention, I wish it to be understood that such changes in construction, design, and materials as come within, the scope of the appended claims may be resorted to without departing from' the spirit of my invention.

Having thus described the invention, what, I.

securing the guard member and clamping memtubular handle and having a bifurcated portion claim as new and desire to secure by Letters Patent is:

1. In a safety razor, a guard member having an elongated slot therein centrally thereof, a

clamping member, a flat lug integral with the" clamping member centrally thereof and freely passing through the elongated slot, said lug having a keeper slot extending inwardly from one side edge thereof, a, tubular handle fixed to one end of the guard member and extending therefrom in parallel relation thereto, and a latch element slid'ably mounted said handle and releasably seated. said keeper slot for clampingly guard member, said extending therefrom to receive said lug, a locking tongue connected to and bridging the space between the furcations of the bifurcated portion of the. latch element for seating in said keeper slot to clampmgly secure the clamping member to the I tubular handle having a slot therein, and a manipulating element fixed to said latch element and extending through the last named slot whereby said latch element. may" be slid back and forth to latching and unl'atchih'g positions. 1 w h V X ASCOO;
