RAZOR.

Application filed October 26, 1916. Serial No. 127,818..

To all whom it may concern:

Beit known that I, Osnon A. CLARK, a citizen-of the United States, and a resident of Newark, county of Essex, and State of- New ersey, have invented certain new and I useful Improvements in Razors, of which the following is a specification.

This invention relates to a razor which is of the type that employs removable blades, these thin material cheap to make, andjthe blades are adapted to be destroyedand thrown away and replaced by anew blade when it is necessary.-

The razor is of this kind and is provided 2 with a holder for the blade, which holder permits a ready'insertion of the blade longitudinally so that thereis no danger of cutting the hands in inserting the blade, the blade when in place being firmly held in position by reason of the holder being constructed so as to extend upward along the thin blade to that it does not vibrate when used for shaving, the holder also having its end constructed so that it yieldingly resists any longitudinal outward movement of the blade, in this way preventing accidental.

sliding-of the blade in the holder. The holder is furthermore improved inthat it has a means'for engaging the blade to permit the blade being slid withitsouter endbeyond the outer end of the holder so.

that it can be grasped for its complete withdrawal, this initial or starting'movement of the blade being thus made safe by prevent ing the cutting of the fingers in the removal of the blade, such expellingmeans'be'ing' preferably placed so that the handle portion, providing for its manipulation, projects flOlll' the rear or back edge. of the holder.

The invention also consists in minor 1mprovements to bemore fully described hereinafter and which are also embodied in the,

clauses of the claim.

The invention is illustrated in the accompanying drawing, in which Figure 1 is a perspective view of the improved razor. Fig. 2 is a view enlarged over the size shown in Fig. 1, this figure being partly broken away to more clearly illustrate the interior construction and embodying one type; of holder with the blade in position, the blade also being shown in dotted outline in the position it assumes when partly expelled blades being usually made of for which reason they are make it rigid enough so 1 slight spring action to from the holder. Fig. 2, and Fig. in Fig. 2. Fig. 5 is an enlarged top view of the left end'ofthat" part of the razor illustrated in Fig. 2.

V Fig. 3 is an end view of In Fig. 1 I show the razor provided with 4 I j I of handle 10 to which is pivoted the holder of the blade, the holder the usual form being'usually made'by folding over a strip of metal, the folded over i cheek-pieces 11 which goto make up the shank of the holder, which shank is ivoted, as at 12, to the handle 10 sothat the holder can be swung into the space between the sides of the handle, as is usual in razors.

The cheek-pieces 11 are preferably integral with the projecting leaves 13 which are.

The outer endof the holder'is open, through which open end the: bladejis inserted and withdrawn, and adjacent to said open end the between them than tween 'thejaws in order tofform a yielding means to prevent the, withdrawal of the '95 I outer ends of the jaws, asa't"1 9,'"are constructed so thattheyform a smaller space the" normal distance beblade by accident, and to prevent the move-I ment of the blade in the holder during the act of shaving. In the drawing this reduction of interval between the'ends of the jaws is provided for by bending the outer ends 19 of the jaws slightly toward each other,

as will be clearly seen from Figs. 3 and 5.

In other words, whentlreblade is in position the outer edge 20 of the blade passes within the pinched or bent ends1'9 of the jaws and the jaws have a curely holds the blade in position.

bite which se- In order to permit sliding of the blade to a position where it is thus held, the jaws are cut away as at 21 to provide a finger space so that the finger can still engage the end 20 of the blade or the end 22 of the backing 18 when'the blade arrives at its proper position in the holder, that is, with its outer edge beyond the turned ends of the jaws.

The shank is preferably provided with a filling block 23 which is secured between the cheek-pieces 11 and thus provides, with said cheek-pieces and the back edge let of the holder, a channel in which a slide 2& is placed, the slide having a longitudinal path of travel and being adapted to be manipulated from the outside, one means being in the form of a finger-piece '25 whichprojects through the slot 26 in the back of the holder.

The slide is disposed so that the distance between thefront edge 27 of the slide and a point slightly withinthe bent ends 19 of the jaws is no less than'the length of the blade 16 or of its backing. In this way the blade is insured against being longer than the distance between the bent ends of the jaws and the forward end of the slide, and it is thus held against any longitudinal movement, any backward movement being resisted by reason of the blade abutting on the slide and any forward movement being resisted by reason of the blade engaging the slightly bent ends of the jaws. \Vhen, however, it is desired to withdraw the blade, the fingerpiece 25 is slid forward, usually by the thumb,-and this slides the blade forward to the position shown in dotted outline to the left of Fig. 2, presenting the blade in a manner so that it can be grasped at a place other than near its cutting edge and can be safely withdrawn from the holder. On the insertion of the blade, and to easily overcome the resistance of the ends 19 or the jaws, the

It will be evident that the holder is stiff enough to permit the installation of any of the usual forms of guards that are placed on razors to transform them into'safety razors.

It will be understood that slight changes may be made in the constructionwithout departing from the scope of the invention.

-Having thus described my invention, I claim:

1. A razor comprising a blade of the wafer type, a holder into which the blade slides longitudinally, the holder having spring jaws extending so as to grasp the blade well toward its cutting edge, the jaws having their outer ends bent toward each other so that the distance between them islessthan the thickness of the blade, and a stop for the inner end of the blade disposed so that. the blade is halted when its outer e'ndis within the bent ends of the jaws whereby the blade is firmlyheld between said jaws, said jaws being separated from one another a substantial distance back of said bent end portions, end of the blade between said aws moves said bent portions of the jaws apart and permits the insertion of the wafer portion of the blade therebetween.

2. A razor comprising a blade of the wafer type, a holder into which the blade slides longitudinally, the holder having spring jaws extending so as to grasp the blade well toward its cutting edge, the jaws having their outer ends bent toward each other so that the ends abut, and'a stop for the blade disposed so that the blade is halted when its outer end is within and in contact with the bent ends of the jaws, the ends of the jaws being cut away between the bent ends and the back of the holder to form curved converging front ends to the jaws, whereby an upward initial insertion of the inner end of the blade parts said bent ends.

In testimony that I claim the foregoing I hereto set my hand this25th day of Octo-- ber, 1916.
