SAFETY RAZOR.

Specification of Letters Patent. Patented D131'. 21, 1922.

Application filed Noveniber, 1919. Serial No. 341,024.

T0 @ZZ lw zom it may cme-cern Be it known that I, daarna J. Curtain, a citizen of the United States, residing at Detroit7 county of l.Vayne, State of Michigan, have invented a certain new and useful improvement in Safety Razors, and declare the following 'to be a full, clear, and exact description of the same. suoli as will enable others skilled in the art to which it pertains to malre and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to safety razors and the object of the invention is to .provide a safety razor which is inexpensive to manu- 'act-ure and which is very eiicient in operation. A further object of the invention is a safety razor frame of a single piece of stamped sheet metal and provided with lugs ou one side over whicha razor blade is laid in position and held in place by a spring and provided with integrally formed guards for the cut-ting edge of the blade and further having a spring for releasably retaining the blade in position. These and other objects and the several novel features of the invention are hereinafter more fully described and claimed and the'preferred form of construction of the invention is shown in the accompanying drawings in which- Fig. l is a plan view of the safety razor.

Fig. 2 is an edge view thereof.

Fig. 3 is a view of the under side of the safety razor.

Fig, 4 is an enlarged section taken on line it-et of Fig. l.

Fig. 5 is a cross section on an enlarged scale taken on line 5-5 of Fig. l.

6 is a perspective view of the razor showing the manner in which the blade is positioned ou the frame.

The device consists of a frame formed neferablv of sheet metal and having a handle l at one end and guards 2 and 3 at opposite edges adjacent the other end thereof providing guards for the safety razor blade which are of the usual shape adapted to prevent the user from cutting himself. At, the end 23 of the handle is a hole l for convenience in hanging up the safety razor. As will be noted more' particularly in Fig. et, spaced lugs 5 and 6 are stamped up from the frame being positioned alongY the longitudinal center line thereof and a double ended spring Tf is Vsecured tothe lfety razor frame between the lugs by rivets 8 as shown more particularly inFig. d. The razor blade 9 is positioned onthe frame over the lugs 5 and 6.` The razor blade is provided with a slot l0 as shown in Fig. 6 slightly wider than the width of the spring to allow positioning vof the blade over the said spring. Then the blade has been thus positioned as shown in Fig. i, the double ended spring 7 holds thev blade on the lugs and in tight engagement with the frame l. In operation7 the razor blade 9 is slipped over one end of the vspring 7 until the aperture 10 in the blade passes overthe opposite end of the spring 7 and takes the position in Fig. 6. At this point by movement of the blade in the direction of the arrow in said Fig.'7 the blade is moved until the slotv l0 therein engages over both lugs 5 and 6 whereupon the spring? forces the said blade to the position shown in Fig. 4 and holds the blade in this position. It will be noted that the spring 7 is provided with upturned ends at` l2 and 13 to allow the blade to be readily slipped under the spring and the lugs prevent the blade from movement when in use. When the blade and frame have been assembled vas shown in Fig. l. the operator may use the same for shaving after the manner of an ordinary razor and the closeness of the shave depends upon the angle at which the blade is held relative to the face.

It is to be noted that` after the completion of shaving, the blade may be removed from the frame permitting the blade and frame to be readily cleaned. Another particular feature of the invention is the low cost at which the razor frame can be made, it being stamped from a single piece of sheet metal with one stamping which cuts the metal in the shape shown and provides the guards 2 and and at the same time forming the lugs 5 and 6 therein and the aperture 4 in the handle l.

Fromthe forcofoing descri tion it becomes I claim and desire to secure by Letters Patent of the United States is 1. In a satety razor, a sheet metal `frame having guards :formed on each side 'or a portion o'l its length at one end, a pair of spaced lugs termed in the said end, a flat` spring fxedly secured to the 'traine ljietn'een the lugs ain` extending thereover, a razor blade having a slot practically centrally between the ends to receive the lugs, said lugs preventing longitudinal displacement o. the blade and said spring being greater in length than the length ot' the slot with the ends thereof engaging the blade.

2. A safety razor comprising a llat sheet metal frame member provided with guards on each side thereof adjacent one end `for a portion oi its length, the remaining portion being shaped to form a handle. spaced lugs integrally formed at the guard end and on a longitudinal center line of the trame, a flatspring tixedly attached at its center to the guard en d between the said lug members, the free ends thereof extending over and beyond the lugs, and a slotted blade adapted to be inserted beneath the spring, each lug engaging a respective end of the slot and the spring member being greater in length than the blade slot and engaging the blade.

3. A safety razor comprising a flat sheet metal frame formed to provide ahandle for a portion of its length and having guards on one edge for substantially the remaining portion of its lengthlugs provided thereon substantially on the longitudinal center line of the frame and spaced apart, a flat spring member fixedly secured to the frame between the said lugs and extending each Way therefrom beyond the lugs,` a centrally slotted razor blade, the spring being longer than the slot and the slot being slightly Wider than fit over the said lugs, the tree ends ot theV .spring engaging the blade.

'lf. In a safety razor, a frame member provided With guards iter a blade, lugs provided on the frame spaced on a line parallel with the edge ol? the guards, a flat spring ineinber lixedly secured to the :traine between the lugs, the :tree ends thereol' extending each way over each lug out ot contact therewith, a razor blade adapted to be inserted beneath the spring and apertured to reeeiverthe lugs, the aperture being less in length than the length of the spring with the ends ot' the spring bearing upon the blade adjacent the lugs.

5. A safety razor comprising a lint sheet metal member shaped to provide a handle :tor a portion oi its length. and provided with guards along opposite edges substantially for the remaining portion of its length, a pair ot spaced lugs `t'ormed integrally ou the frame centrally between the said guardsn a fiat leat spring member secured to the frame between the said lugs, the ends extending over the lugs and being curved thereover and out of Contact therewith, the ends of the said spring being upwardly turned, a razor blade having a longitudinal slot therein greater in width than the width of and less than the length of the spring permitting introduction o't the blade thereover substantially as described, the slot being shaped at the ends to engage about each lug respectively, the ends ot the spring bearing upon the blade adjacent the respective lugs.

In testimony whereof, I sign this speeification.

JASPER J. CURRIE.
