T0 all whom t may concern -Be it known that I, Hanny F. CRANDALL, a citizen of the United States, residing at Racine, in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in Safety-Razors, of which the following is a specification.
My invention relates to safety razors, and has for its object to provide an exceedingly simple, cheap and effective safety razor.
To these ends it consists in the various features of construction and arrangement of parts adapted to coperate in a manner substantially as hereinafter pointed out.
Referring to the accompanying drawings, wherein I have illustrated the preferred embodiment of my inventionf-Figure 1 is a top plan view of the holder, showing the blade in position as inserted therein; Fig. 2 is a side elevation of Fig. 1; Fig. 3 is a view showing a blank from which the holder is formed; Fig. l is a top plan view of a similar holder but formed from material having a diilerent cross section; Fig. 5 is a bottom view of Fig. el, partly in perspective; Fig. 6 is a side elevation of Fig. d; and Fig. 7 is a cross section of Fig. 5 along line fir-B.
@ne of the objects of my invention is to make a complete safety razor which shall comprise only two parts; that is, a holder for the blade and a separable razor blade, and these shall be ada ted to correlate to each other so that the lade may be easily placed and held in operative position on the holder and detached therefrom, and when assembled the parts being in the best position for practical use. Furthermore, I prefer that the'resiliency of the side members of the holder alone will retain the two parts of the razor in operative position.
The holder 1, which is preferably made of a single piece of sheet steel cut in the form shown 1n Fig. 3, has a body portion 2 and curved reduced end portions 3 terminating in angularly disposed head portions 4, having inwardly arranged comb members 5. The blank is then turned into a concevoconvex form at its central portion that is gradually increased toward the end of the blank in a manner to reduce the diameter as it approaches the curved portions 3, resulting in a gradually tapering form having srtaight convergin edges. The next step consists in bendingit at its middle into semicircular form, brin ing the ends of the body portion close toget er, with the curved and of" the angular extremities disposed laterally and 1n the same plane.l The heads 4 are then folded inward in a manner to'bring the lend portions of the comb members 5 in close proximity, their bodies in parallel relation and with the head portions 4 at approximate] a 45 angle 'with 'the body hol er; the comb members 5 bein given a slight curve upward towar the holder, as shown in Fig. 2, and the line of fold milled or otherwise tinished in a manner to operatively receive the ends of a blade 6, as shown in Fig. 1. The side members of the holder are lmurled for the purpose of affording a b'etter grip for the user.
All that is necessary to insert or remove a blade is to spring the two side members of the holder apart by a pressure of the finger or thumb between them in front of the neck of the holder, the resiliency of the side members being suiiicient 'to securely hold the blade in operative osition and permit ready removal thereof? In Figs. 4, 5, and 7 I have shown substantially the samek form of blade holder made out of heavy wire, the handle portion havlng a semi-circular head 7, forwardly converging sides S that terminate in laterally curved portions 9 that terminate in blade holding, or head members 10, that are turned downward and toward the body of the holder at approximately an angle of 45, the extremities thereof being turned inward in parallel relation and at rlght an les with the longitudinal center of the ho der and milled to form a guard comb l1. for the edge of a blade, the-head members 10 being provided with grooves 12 for the reception of a blade 13, as shown in Fi 7.
In operation the bla es are released or secured in the same wa as in the form described irst. Having s own both preferred and modified forms of my invention, I do not wish to confine it closely to either embodiment, as various minor changes may be made therein without departing from the spirit of m invention.
What I c aim as rn invention, and desire to secure by Letters atent, is:
1. A safety razor blade holder formed of a single piece of metal, having forwardly converging resilient side members terminating in outwardly turned diverging portions disposed at an angle with each other and having downwardly turned heads terminatal; azi angle of appeoximalely 45 with elle body of elle holder and leimiiiafing in iii- Waiclly lumecl sepaieltecl comb members clisposed parallel with each other, saiol heads being freely movable bodily al: all limes fno- Ward or from eacli other im parallel rela- ILion im a manner lo receive a lolade and secure il; iii operative position by means oi" pressure distributed equally across its eppesilte enfle.
