SAFETY-RAZOR.

Application led September 22, 1910.

T 0 all whom t may concern.'

Be it known that I, FLOYD D. JONES, a citizen of the United States, residing at Kansas City, in the county of'Jackson and State of Missouri, have invented certain new and useful Improvements in Safety-Razors, of which the following is a specification.

rThis invention relates to safety razors and has for its object the production of a safety razor susceptible of adjustment for right or left hand shaving like an ordinary razor or of being used like a hoef7 of simple, strong, durable and cheap construction.

To this end the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawing, in which Figure 1, is a side elevation of a razor embodying my invention. Fig. 2, is an enlarged vertical section on the line II-H of Fig. 1. Fig. 3, is a horizontal section on the line TTI-HI of Fig. 1, wit-h the handle in plan view. Fig. 4, is a vertical section on the line IV-IV of Fig. 1. Fig. 5, is a side view of the razor arranged as a hoe. Fig. 6, is a detail perspective view of the guard and blade clamping plate. Fig. 7, is a detail perspective view of the cutting blade. Fig. 8 is a plan view of a fragment of a modified form of handle.

In the said drawing, 1 indicates the guard, the saine consisting of a plate which is curved at its lower end as at 2, said lower end being toothed by preference, to constitute a comb, common in safety razor construction, and at opposite ends the plate is provided with forwardly projecting flanges 3 and 4, the former extending upward a considerable distance beyond the latter. At the upper end of flange 3, the plate is bent horizontally to form a channel portion 5, the arms of said portion converging rearwardly at a slight angle so that the channel 6 shall be of dove-tail form, the front or vertical wall 7 of the channel occupying a plane slightly forward of plate 1 to provide a downwardly-disposed shoulder 8, for a purpose which hereinafter appears, and said front wall is provided about centrally of its length with an aperture 9, and in the same vertical plane as said aperture the horizontal walls of the channel portion are formed with vertically alined openings 10.

Serial No. 583,225.

The plate 1 is also provided at suitable points with outwardly projecting protuberances 11 for engagement with openings 13 in the cutting blade 12, said blade being adapted to fit flatly against plate 1, and snugly between flanges 3 and 4 thereof with its upper' edge against shoulder 8, and its cutting edge depending slightly below the upper ends of the interstices between the teeth of the comb.

To hold the blade in position, the clamp plate 14, is secured frictionally by a pivot 15, to the front wall of the channel portion of the guard plate so that it may be turned in the direction indicated by the arrow, Fig. 6, one end of the plate passing between pivot 15 and flange 4 until it attains the position shown in Figs. 1, 2, and 4, in which position the plate overlaps the greater portion of the cutting blade and bears at one end against flange 3, its lower edge bearing upon the upper end of the flange 4. It will be understood of course that this clamp plate 14 is of such material and stiffness and so frictionally secured on the guard plate that it will hold its operative position and clamp the cutting blade firmly against the guard plate so that the former cannot move away from the latter in the shaving operation.

The handle consists, by preference, of a part 16 and a part 17 of such construction and arrangement that it may be lengthened or shortened. In the preferred construction the part 17 of the handle is a resilient sleeve and is provided with a longitudinal slot 18, and the part 16 projects into said sleeve and is pivoted thereto at 19, so that part 16 will fold into part 17 like a blade into the handle of a knife. Tf desired the resilient sleeve 17 may lit telescopically on part 1G so that the latter may be slid into the former to reduce the length of the handle, in which case the sleeve will be slit as at 2O see Fig. 3 but not slotted, and will clasp the part 16 with suflicient friction to prevent accidental movement. Tn both constructions the part 16 is adapted to be slid into the dove-tail channel G of the channel portion 5 of the guard plate and is provided with protuberances 21 for pivotal engage ment with openings 10 of the horizontal arms of the channel portion, the arrangement being such that the handle may be swung in the direction indicated by the arrow Fig. 3, or in the reverse direction, so

that the handle shall project in the proper direction to accommodate its convenient use in either the right or the left hand, said arms of the channel portion havingaresilient relation so as to clamp the handle reliably in either position.

To employ the razor as a hoe the sleeve 17 is beveled at one end at 22, and provided with a notch 23 opening off the beveled endv and is also flattened at the upper end of the beveled surface at 2d, so that the portion above the notch may be forced into the channel portion. Then thus arranged the notch receives the lower arm of said channel portion and the resilience of said arms clamps the handle reliably in position, so that it will not become detached in the shaving operation. lt will be noted by reference to Fig. 5, that the beveled surface 22 lits `latly against the front wall of the channel portion so that the blade stands at an acute angle to the handle as customary in safety razorsof the hoe type. lt is apparent that in the shaving operation the clamp plate liL is interposed betweenthe face and the blade and that the comb end of the guard plate also engages the face and prevents the blade from digging into the shavers face. The interstices of the comb also provide for the escape of the lather scraped up by the blade in the shaving operation.

From the above description it will be apparent that l have produced a safety razor embodying the features of advantage enumerated as desirable and l wish it to be understood that l do not desire to be restricted to the exact details of construction shown and described as obvious modifications will suggest themselves to one skilled in the art.

l claiml. ln a safety razor, a guard plate made from sheet metal and bent to form upper and lower parallel portions, the latter occupying a plane rearward of the former, and also bent to form a rearwardly projecting spring arm and a downwardly facing shoulder' at the unction of said portions and to form a rearwardly projecting spring arm at the upper edge of the upper portion and a rearwardly curved comb at the lower edge of'the lower portion, the-'last-named portion having a protuberance on its front face below the said downwardly-disposed shoulder.

2. In a safety razor, a guard plate made from sheet metal and bent to form a horizontal rearwardly opening channel portion and a depending portion parallel with the face of the channel portion and disposed in a plane rearward of said face thereby forming a downwardly-facing shoulder on the channel portion, said depending portion terminating at its lower margin in a rearwardly curved comb portion, and having at its ends a pair of forwardly projecting flanges of unequal lengthone of the flanges extending from the said shoulder to the lower edge of the said depending portion and the other dange from a point some distance below said shoul der to the lower edge of the said depending portion.

3. ln a safety razor, an extensible handle comprising a sleeve portion and a shank to fit within the sleeve portion, Ahe said sleeve portion at one end being beveled and provided with a notch at the lower end of the beveled portion and with a beveled surface at the upper end of said beveled portion extending substantially'parallel to said y notch.

shoulder', and a clamping plate pivoted on' said channel portion, said blade clamping portion having a pair of flanges extending from its lower edge toward said shoulder, one of said 'flanges terminating short of said shoulder to aermit said clam ain@ )late to` swing past it into abutting relation with the other flange.
