Description

March 14,1944. G. LENTA' ONE-PIECE SAFETY RAZOR Filed Jan. 18, 1941 Patented Mar. 14, 1944 STATES OFFICE ONE-FIECE SAFETY RAZOR Application January 18, 1941, Serial No. 375,675 In France December 26, 1939 3 Claims.
My invention relates to improvements in onepiece safety razors in which the blade is clamped between a guard plate and a comb plate; and the objects of my improvements are, first, to provide a safety razor in which all parts are held together and, therefore, cannot be mislaid or become lost; and, second, to aiford facilities for readily exchanging the blade and for a quick cleaning of the razor.
I attain these objects by the safety razor illustrated, in three forms of invention, in the accompanying drawing, in which- Fig. 1 is a front elevation of one form of invention; Fig. 2, a side elevation of sam with the guard plate and blade raised into a position nearly vertical to the comb plate for the purpose of exchanging the blade or cleaning the razor; Fig. 3, a top plan view of the comb plate; Fig. 4, a top plan view of the guard plate; Fig. 4a. a side view of the guard plate; Fig. 4b a bottom plan view of the guard plate; Fig. 5 is a top plan view of one of the tenons of the guard plate; Fig. 5a a side View of a tenon; Fig. So an end view of the tenon.
Figs. 1-4 illustrate the most simple form of invention. The handle 4 is split at one end to form two bulbed wings '5, The comb plate (Fig. 3) comprises two symmetrical halves Z and 3, separated throughout by the longitudinal slot I, each of which is securely fastened to one of the wings 5. The guard plate 6 is inserted into the razor by slightly springing apart the wings 5 and sliding the tenon 7-40 into the slot l and onto the comb plate 23.
The guard plate 6 (Fig. 4) possesses two lateral tenons 'l-lll which fulfill three functions: the centering of the blade, its clamping fast between comb and guard plate, and the guiding of the guard plate during the tilting operation (Fig. 2). These tenons or heels possess a semicylindrical portion 1, which correspond to the tenons of the common guard plates, a portion 8 somewhat wider which eliminates the vertical play of the plate, and a heel 9 which abuts against the wings 5 during the tilting operation and also, therefore, prevents the guard plate from becoming entirely separated from the comb plate. Two grooves l 9 on these tenons permit the guard plate to slide easily onto the comb plate and thus assure the clamping fast of the blade between the said plates.
The blade I I which is provided for this type of razor and for those based on the same -prin ciple described in the following, comprises a central openin H and two semicircular portions on its lonigtudinal axis, which abut against the tenon "l and are guided by the latter. It is obvious that these blades also may be used in any safety razor which is provided with the ordinary type of guard plate.
What I claim and desire to secure by Letters Patent is:
1. A safety razor comprising a handle, a blade supporting plate divided into two spaced portions secured fixedly to said handle, a guard plate and means on said guard plate extending into the space between said spaced portions and cooperating with said portions whereby said guard plate may slide on said portions and tilt to a position substantially perpendicular to said supporting plate for cleaning and blade replacing purposes.
2. A safety razor comprising a handle, having one end thereof split into two spaced ends, a blade supporting plate divided into two spaced portions secured fixedly to said ends, said spaced portions being so cut at their adjacent sides as to define a space between said portions which is greater at the center than at the ends, a guard plate and means on said guard plate extending into said space and cooperating with said portions whereby said guard plate may slide on said portions and tilt to a position substantially perpendicular to said supporting plate for cleaning and blade replacing purposes.
3. A safety razor comprising a tubular handle split at one end to define two spaced ends, a blade supporting plate divided into tWo spaced portions secured fixedly to said spaced ends, a guard plate and tenons on the ends of said guard plate extending into the space between said spaced portions and cooperating with said portions whereby said guard plate may slide on said portions and tilt to a position substantially per- GIUS-EPPE LENTA.
