SAFETY-Razon.

To all whom it may concern:

Beit known that I, ABRAHAM;- Zimniismiii, a citizen -of the United States, and a resident ofthe city of New York, borough of Manhattan, county and State of New York, have invented a new and Improved Safety- Razor, of lwhich the following is a full, clear, and exact description.

My invention relates to a new and useful improvement in theI art of safety razors and more particularly the invention involves' a retainer or cap plate used on safety razors,

the construction of which especially adapts it for use with blades which have been w orn down more or less after honing or stropping. The object of my invention is to provide a retainer or cap platehaving the parts there-- on which coact with the blade seat to hold it in position td one side of a centralv line through the capIl plate whereby portions of i the cap plate bear on the top surface ofa i v blade for unequal distances, the wider portion of the vcap plate being adapted for use with a new blade while the narrower portion thereof is especially adapted for use with a blade which has become lessened in parts with which it is used incombination'4 width dueto honing or stropping. The construction of the cap plate and the remaining will be more particularly described herein@ after and set forth in the claims.;

lReference may be had to theyaccoinpanying drawings forming a part of this specification, in which like referencecharacters denote corresponding parts iii all the views,

and in which- Figure 1 is a perspective View of the de.

vice; Fig. 2 is a vertical transverse section on the line 2 2 of Fig. 3; Fig. 3 is a top.

The improved retainer or cap plate is set forth and described in connection with'a particular form of holder although it is ob` vious that the cap plate may be used with any form of holder as my .invention relates to the cap plate and not to the holder itself.

The safety razor in which I have illustrated my improvement preferably consists of a piece of sheet metal bent in the form of a tube and having extendin therefrom a Haring portion 2 bent in the orm of a loo to constitute a supporting member whic forms a holder with the handle 1. The

louter edge ofthe holder is provided with al tively.

' Specification of Iletters Iatent. atted Nov, 14,. 1911, Application filed September 8, 1910. Serial No. 580,966.

i la serrated portion 3,.between the teeth of .whichathe hairs may project in the operation. of shaving, so that they can comein engagement with the edge of the blade. This edges 5 and 6 on opposite sides by means ofthe cap plateor retainer 7, the

,b lade is indicated at 4, and .preferably con- 'sists of a permanently concaved memberhaving thereof." The blade is secured to the holder mfy invention, the retainer being'in the form o a concave member which engages the.

blade 4 adjacent its cutting edges whereby the blade is held in position on\'the holder;

'the retainer'inay be of 'springy-material if so desired so as to permitv of easy attachment andrin securing of the parts. Forv the purpose of securingl the retainer on the holder and thus securingthe blade 4 in place a screw-threaded lug 8 extends later-all from the concave face of the retainer whic l is adapted to project through openings 9, 10, located in the blade 4 and holder 2 respec- In order to lposition the cap-plate and the blade on the

holder positioning lugs

11,12, are extendedlaterally from the concave face of the retainer or cap plate and .preferably at equal distances from the screwthreaded lug 8 so that in whatever position the cap plate is used these

lugs

11, 12, may engage in suitable openings in both the blade and the holder which are adapted to receive them. i v

The improved feature of my invention and the one involving the novelty thereof lies inl the relation between the threaded lug 8 and the other lugs 11,' 12, with respect to the cap plate 7 these lugs lie in theA saine straight line whether they adjoin the cap plate or retainer and this line, while it is parallel vwith the opposite edges of the cap plate, it is nearer one edge than the other or it is, so-to speak, eccentric, whereby the distance between the plane passing through the lugsand the edges of the cap plate is vunequal. The purpose of'such construction is to permit the cap plate or retainer to be l used with lblades of varying widths; originally these blades are substantially of the same width but through being used and with consequent honing and stropping they bel sired to usea smaller sizedblade, the thumb 1. 'screw 15 can be loosenednand the retainer 7 o 5' cent the edge ofthe blade which'it is desired' n to use in shaving.`

The operation ofthe device will be readil understood when taken in connection Wit the above description. When it is desired lojto'shave, a blade Ais placed on the holder 2 "so that the openings therein will. extend in t alinement with theopenin'gs in the holder. :The retainer 7 is.it'henplaced in position I withthelug 8 andflug's'lland 12 extending ndv b ade.j'gThe parts .are-'secured in their lwhichy may :be `screwed u `to 'the desired `gl i tn esfs'.ay vThe serrated e 3'thus forms becomes worn and has tobe sharpened l( icnnfn to a smaller size, or'ifit should be de- Qreversedse as to brin its side of lessvmagnitude'overin juxtaposition tothe guard `edge y3. .This is permitted by the symmetrical1ocationA of the

lugs

11 and 12 with respect to -the screw 8.

While I have shown one embodiment'of vajuuard'ior theedgefoft e blade 4, perf 'jinntting-vthe hairs to come in contact therewith, and yet preventing the blade from dig- .j D `termediate of the edges ofthe cap'plate, the f into the iiesh any' dlstance. When the la e distance vfrom one edge to the said means bemy invention', I do not wish to be limited` to the specific details thereof but desire to be 35 protected in the various changes, alterations, and modcations which I may make Within the-scope of the appended claims. Having thus described my invention I claim as new and desire'to secure by Letters 40 Patent: i j v 1. As a new article of manufacture a cap plate for safety razors having a p urality of ugs extending' laterally thereo the said lugs lyinin the'same vertical plane, the distance tween the said plane and one edge of the cap plate being different than other edge of the said cap plate.

2. vAs a new article of manufacture, a ca plate for safety ranors having means exten ing therefrom adapted for coperation'with vthe 'distance between the said plane and the 'y a blade and a blade'seatlin order to. position the blade thereon, the said means being in- 5 ing greater than the distance from the other edge to the said means. p

In testimony whereof I have signed my name to this specification in the presence of 60 vtwo subscribing witnesses.
