SAFETY-RAZOR.

To all/whom t may concern.'

Be it known that I, EDWIN C. MADDEN, a citizen of the United States, residing at New York in the county of New York and ew York, have invented certain new and useful Improvements lin Safety- Razors, of which the following is a specification.

This invention pertains to safety razors and as to certain of its features is an improvement upon the construction set forth and claimed in Letters Patent No. 1,022,429 granted to me under date of April 9th, 1912. the present embodiment is such that an up or down stroke may be had with the cutting edge ofthe blade traveling in advance of the handle, a point which makes for ease of'manipulation and efectiveness in operation Aside from this the present structure exhibits several distinct changes over the previous construction with the advantages adherent thereto and which may be lenumerated as follows:

The main object of the invention is to provide an improved form of bed or supporting plate which admits of the ready placement of the blade thereon and the subsequent. clamping of the blade in position by a combined swinging blade clamp and vcap or cover plate.

, A further object is the provision of lugs of special form which enter recesses formed at each end of the blade to engage and position the latter.

A still further object is to so mount the supporting bed 0r plate within the spring supporting yoke that it may, by a slight pressure rightlyV applied, be swungl lfrom one to another of its operative positions for shaving, or turned down into folded posi i tion, for the purpose of packing or storage within a suitable receptacle or container.

Another object resides in the provision of spring means, likewise brought about through the resiliency of the supporting yoke for holding the clamping or cap plate `n its closed or open position with relation to the blade and its supporting plate.

A still further object resides in the provi-- sion ofa special orm of guard or comb which protects or shields the corners of the blade so as to prevent `the nicking of ones face therewith. The blade which is of the Idouble edge type, though but one edge is Specification of Letters Patent.

As under the former constructionl VPatented Nov. s, 1921.

exposed at a time, is provided with a pair of notches, one at each end, and likewise with an opening extending therethrough, .the latter serving a double purpose, namely,'to assist 1n the manufacture of the blade and to serve as a mark whereby the, user can identify the edge which he may have used, or may have stroppedl for use.. With these and-other objects and advantages in view,

yas will hereinafter appear, reference will be Figure 1 is a perspective view of the razor with the blade in position for making a down stroke; Y

In said drawings 1 denotes the handle to which is secured a yoke shaped member 2, the two arms of which are alike in form and each of which is provided at its upper end with an outturned inger or pintle member 3. Each arm is preferably enlarged to a slight extent below the pintle, as 4at 4, and in the outer face of each enlargement there is provided or formed a. socket or recess 5 ner. The formofthe bed plate will be best understood upon 'reference to Figs..4 00.8,

' 'when'the' razor' is in use.

inclusive, and F ig.-10v. It may be said toA .plate proper denoted by 6, which extends forwardly from and at a slight angle to a body element or cross bar 7, the latter having formed at each end thereof a wing 8 substantially semi-cylindrical in .outline` and standing at right angles to theelement 7. The forward edge of the bed plate is fashioned into a series of guard teeth 9 andthe outermost tooth at A a plane slightlyabove the othersV so that they stand closeto the corners of the blade and prevent 'the corners from cutting ones face The blade 11 is of comprise a bed the double edge type, see Fig. 13, and is provided at itsopposite ends with a notch l2,

the blade being likewiseA provided with an opening 13 located to one side of the medial ine thereof, which, aside from beingv employed for a useful purpose in vthe manufacy "The bed fthe'rear edge whereof'is undercut ture of' the blade, also serves as an index to enable one to identify one or the otheredge of the blade jas having been used.

The blade when positioned and clamped upon Ythebed in a manner presently to'appear, has'yits exposed or forward edge firmly heldlinproper relation to the guard teeth 9, that'fis, the edge is separated from the teeth Vby a space of nine ten thousandths of an inch, more or less, as experience dictates, but, as abovenoted, the outermost teeth -10 of the guard lie in contact, or substantially so, with' the cornersiofthe blade and (see Fig. 7).

mounted on'the spring thus prevent the corners from cutting or nicking one. Said end-teeth are likewise turned downwardly at their outer ends below lthe plane of the intermediate teeth 9 Each of tl1e.wings `8 is proopening 17 through which the the combined bed plate and and 10) being thus'pivotally yoke 7 Each wing is vided'with an ngers- 3 pass, guard (teethl likewise provided witlna pair of inwardly and 21 in -the outer projecting lugs or

teats

18 and 19 upon the` '.inner .face thereof,`which lugs are produced.

by fa' punching ror upsetting action, which likewise forms sockets or depressed seats 20 faces of each `of the wings;`

Lugs

18 and 19 lie equi-distant radially from the openings 17 andare adapted to enter the sockets 5 in the yoke4 as the bed plate is swung to one or the other of its operative positions,-Figs. 1 and 2, and to hold the plate in suclr positions, the spring action of the yoke securely holding the parts against accidental displacement. To hold the blade in place and to protect the rear edge of thelblade, I employ la combined clamping and guard element of the form best shown in ltigs. 1 to 5 inclusive and Fig. l1. Itlmay be said to comprise a clamping plate 22 a rearwardly extending curved guard 23 and two arcuate arms 21, which latter are formed integrally with the plate 22 and lie at right angles thereto. Each arm adjacent each end is provided with an opening 25 adapted for the rcception of the pintles or fingers 3 of the yoke. Each arm is likewise provided upon its inner face withan inwardly extending lug or teat 26, said lugs cooperating with; the

sockets

20 and 21 to hold the clamping guard plate in its open or closed position. The plate 22 at eachendforward of the arms 2i is provided` with a thumb piece 27 by which the plate may be raised free 0f contact with the blade and thrown from the position shown in Fig. l to that'shown in Fig. 3. The distance between the arms 24 will be such that they make close contact with the wings 8 and the outward spring of the arms 2 of the yoke holds the elements 1n proper adjusted posi tion. Thus the various lugs will spring into the various sockets and will beheld there owing to the pressure exerted by the yoke.

As will be best seen upon reference to Figs. 4 and 7,` the bar 7 is curved transversely and that the clamping plate 22 when raised o1' swung back stands clear thereof.

` This arrangement facilitates the positioning ward edge of plate 22 bears firmly upon,

the blade at a` slight distance from the forward edge thereof. The fact that the blade engages the undercut of the lugs prevents the blade from canting or tipping as the clamp is snapped into clamping relationl thereto. lf for any reason the notches l2 should not be correctlypcut so that one end of the blade 'would protrude farther than the other, the guard teeth 10, by reason of their formation, as above described, wi'll prevent said edge from cutting the user. The curvature of the guard 23 is such that as the part 22 is swung forward to clamping position, said guard will not contact the rear edge of the blade Aand will overlie and protect the same against possible injury or prevent the user from being out thereby. When it is desired to remove the blade the clamp may be raised by the` thumb piece 27 or the clamp may be swung away from the blade by applying a rearward dragging pressure u on the outer face ofthe guard 23 which.

will beroughened toiafford the proper thumb or manipulation." lThe parts are readily assembled'and when once assembled so remain,- as there is no necessity of removal of any l' art for' the, urpose of inserting or .with rawing a bla e; nor for the purpose of 'cleansing the holder.'
