ToaZZ whom) it may concern: I

Be it known that I, WVILLIAM H. W. HAMILTON, a citizen of the United States, residing at Buffalo, in'the county of Erie and StateofNew York, have. invented certain new and useful Improvements in- Razors, of which the followingis a specification. v

The object of this invention is to provide an improved razor, which with a minimum 7 amount of alteration instantly meets the demands of those who prefer theold and wellknown types of razors, as well as those who prefer the later developed types of the socalled safety razors.

Another obj eot is to provide animplelnent of this type which embodies the utmost simplicity of construction, and departs as little asnecessary from the long established characteristic shape of the ordinary razor, in fact comprising only three pivotally mounted parts, namely, the bladeholder, the horn, and the guard, the first two .of which are employed when the device is used as an ordinary razor, and the three being operatively associated when the .useis that of asocalled safety razor. n

Persons using razors, generally speaking are of two principal classes, those preferring the ordinary and those preferringthe safety razors, but there are countless numbers who would like in a single deviceto have an ordinary razor with its accustoinedshape when such is preferred, to have -a"safety razor when such suits their fancy, to have a safety razor in the shape of the ordinary to which.

long use has made them partial, to have in such a razor a construction permitting the stropping of theblade exaotly'as ordinary razors, and yet to find a provision for quickly removin a used and substituting-1n,

lieu thereof .a fu ly. sharpened blade.

The present invention wthereforehas for an object the. provision of each and everyot these characteristics, so united and arranged to co-operatein such manner. that the resulting device will meet theobjections and fulfill the requirements of all. 'Simultane. ously itwill be found that the device possessesa simplicity and configuration which make it mostattraetive and which add nothing to the cost'of manufacture.

present invention comprises further novel dei tailsof construction hereinafter fully i i out in the following desoription, whenlread in conjunction, with, the accompanying drawings, in whichFig. l is afiplan vie'wlof the device arranged for-use asa-n ordinary:

Another party, however, or in fact the same person who uses the device as an ordinary razor may desire to use the blade with its guard operatively positioned with respect thereto in which case the guard is oscillated from within the horn and into either of the positions shown in Figs. 2 and 3, the difference bein that the former permits the use of the guarc ed blade by one accustomed to a right-handed use of articles, while the latter arrangement adapts the guarded or safety razor arrangement for use by persons who handle articles left-handedly.

It will be noted that the free end portion of the guard 13 is provided upon its laterally 'oppositesurfaces with slender and relative 1y shallow hook extensions 16, one of which isadapted to surround and slidably grip the adjacent end portion of the blade when the guard is in either of the positions shown in Figs. 2 and 3, thus insuring a complete unitary relationship at all times between the guard and blade as long as the device is intended to be used as a so-called safety razor. By referring to llig. 10, it will be clearly seen how the diverging relationship of the sides 6 of the shank 5 permit the guard to be oscillated upon the bushing 10 transversely of the plane of the blade, so that no flexing of either guard, blade, or blade- 7 holder is required inorder to transform the guard from one side of the blade to the other, or vice versa. Furthermore, after a given blade has been used after repeated stropping and even honing in the usual manner, it is perfectly feasible to slide the used blade from its holder and to replace it by a new sharpened blade, which may then be used for a considerable period exactly as its predecessor before requiring replacement.

laving thus described my invention, what I claim and desire to protect by Letters Patent of the United States is 1. A razor, comprising a holder adaptedto receive "and support a blade longitudinally and in the transversely central portion thereof,said holder having a hollow shank, and

2. A razor, comprising arholder adapted to support a blade transversely central thereof, said holder having-a hollow shank taper-.

ing towards its opposite end, and 'a guard carried by a shank in turn pivotally connected adjacent to and within the said first shank, said second shank being oscillatable with respect to the first shank about its pivotal connection therewith, and angularly movable upon the pivot transversely ofthe first shank to co-operate with either of the opposite sides of a blade within the holder.

3. A razor, comprising a blade holder, a guard pivotally connected therewith, and a handle having a recess and pivotally-connected with said holder and said guard, said guard being adapted to be positioned within the recess of the handle or in operative relation with either side of a blade carried by the holder.

Arazor, comprising a blade holder, a guard pivotally connected therewith, said guard being provided with means to engage a blade upon either side thereof, and a hollowed handle pivotally connected with said holder and said guard, said guard being adapted to remain at will within saidhandle to provide an unguarded blade, or to be oscillated towards either of the transversely opposite sides of a blade carried by said holder. 5. A razor, comprising a blade holder, a blade removably carried by said holder, a guard, and a recessed handle both pivotally connected with saidholder, said guard being adapted to enter and remain within the recess of the handle while the blade is used ing adapted to enter and remain within" the recess of the handle while the blade is used unguarded, or to be oscillated towards the holder and positioned upon either of the either right or transversely opposite sides of the blade while the guarded blade is used either rightor left-handedly, said guard being provided up on its opposite sides at its free end with undercut lugs, operative to engage the adjacent edge portion of the blade, to'pre- 'vent transverse separation of the guard from the blade while in operative relationship."

7. A razor, comprisinga blade holder, a blade removably carried bycsaid holder, a guard, and a recessed handle both pivotally connected with said holder, said guard being adapted to enter and remain within the the guarded blade is used either rightor lefthandedly said guard adapted to be shifted from one to the other side of the blade, first by relative oscillation about their pivotal connection until they are disengaged, then by relative transverse movement upon their pivotal connection until they are againjope-ratively engaged;

a guard p-ivotally connected therewith, said guard being provided with oppositely positioned blade-engaging means; operative to maintain the guard in normal operative relation With-and upon either side selectively adapted tobe shifted from one to the other 7 of a blade carried bythe' holder, said guard side of the blade first by relative'oscillation 7 about their pivotal connectionguntil they are f disengagedy then by relative transverse 1nove 1.
