a blade; a blade for such a razor in .the form of a thin flat, n0n-flexible member; means for engaging the blade and its supporting member consisting of one. or more tongues and cooperating openings, the tongues'beingon the blade and the openings on the other member; and in general the making of a safety razor reduced to its simplest form in all respects.

The construction hereinafter set forth permits the blade support and its handle to be developed from one piece of stamped sheet metal, thereby eliminating the necessity of any forging, machining, or otherexpensive operations thereon, and so greatly reducing the cost of manufacture. The construction also provides a safety razor, the blade of which may be made in a standardized form and interchangeably used withdift'erent forms of supports. These and other objects which will be apparent to. those familiar with the art will more fully ,appear in the following specification.

-Referring to the drawings, Fig; 1 shows ahoe-shaped blade support forming one of the two essential parts-of the complete razor constructed according tothis invention, the view being an elevation of the handle, standing on end; Fig. 2 isaview similar to Fig. 1 but taken at right angles thereto and with the razor blade in position on the handle; Fig. 3 shows another formof holder apd handle the two portions being in ali ent; Fig.4 is a section on the line IV- V of Fig. 3; Fig. 5 is;a persp'ec- 'tiv'e view of a referred formof blade, suitable for' use with any of the supports illustrated; Fig.- 6 shows aspecial blade holder applied to the ordinary formof razor handle; Fig. 7 is an enlarged partial section through the blade and its support,;the blade having been applied to the support, ,fbut not having been moved longitudinally into per nanent engagement therewith; and Fig. 8

.s'ervedi'thatthe handles.

is a :section through the blade and its support showing the relative position after the f blade has been longitudinally moved into fengpgemen't with the support. The lasttwo figures also show a modification in the end of the blade. H Safetyrazors have been made heretofore,

in which ablade of substantial thickness having a pair of slots, each slot having a.

countersunk ledge adjacent thereto, has been combined with a support, the support having a shank pivoted thereto and being provided with an integral guard having a pair of integral lpgs off-set from said guard and adapted to passthrough the slots and enfiexiblewafer steel blades have been provided for attachment to a support by means of proJecting overhanging lugs on the support adapted to extend through holes in the blade, and to engage the blade, holding it means of the resiliency of they blade itself,

Qgage the ledges of-the blade, to hold the I blade and guard together. .Likewise thin "in a curved position against the handle by and without any additional locking member. V The present invention is distinguished from each of these by the fact, among others,

that it does not use a wafer blade, and the blade itself is of uniform thickness through-. out its body and is not bent or distorted in any way either while held in operative posi tion or in order to place'it in operative position. Furthermore the blade of the present device is not held in position by a third part, clamping theblade between s uchthird v part and the handle as has heretofore been} the practice wherever a stifi' blade was used.

' The present invention in all of. its forms provides for holding the'blade andits'sup port togetherby means of one or more ofiset tongues formed integrally with the blade,

which tongues engage the. holder andby their resiliency hold the t .seburely to: getherunder pressure. f

ma roled-up to form "a round handle H shown 3 shows a strai 'ht construction. 1 InFig. '6

the ace of. the ordinary fashioned razor handle; It .e'

is shown a meta member, v11',adaptedtoitaQke bladeinjtlie old" by rolling up a strip of sheet metal to form a suitable hand-hold at one end, the other end being fashioned into a supporting plate S adapted to hold the blade as below described. For example in Fig. 1 the same piece of metal sheet which forms the handle H forms the blade support S. The outer edgeof the supporting portion S has a series of openings 0 therein, which are separated by small grill-like portions of metal G forming a guard portion which readily slides over the face of a person shaving, and permits the blade B, shown in Fig. 2

to come in contact with the beard. The por- I S has cut through it two sets of openings C and C. a In the form shown in Fig. 3 the sheet metal that forms the handle H likewise .forms a blade holding portion S and at each edge of this flat portion the metal is cut away to form a series of openings 0 with intervening guard portions of metal G The outer edge is turned sharply inward, forming a terminal flange F The section shown in Fig. 4 clearly shows the construction just above referred to. The supporting portion S has a pair of openings C intermediate which there is a small rounded hump F The form of handle shown in Fig. 6 comprises the metal bar 1, which is pivotally attached to an ordinary razor handle 2 by a rivet 7. This rivet passes through the forked end of the handle 2, the slot 8 forming this forked portion being extended far enough into the handle so that the tang 9 of the member l'can pass through the slot,-

thus permitting the razor to be used for shaving, with either hand or with either edge of the blade. as will be obvious.

-This member 1 likewise has a flattened blade supporting portion S similar to portions Sand S above described, and this flat portion has a pair of openings C there.- through, with an intermediate raised hump P, as illustrated. The edges of the supporting member S are serrated, forming guard teethG and these serrations are similar on each side of the member, as illustrated.

The preferred form of blade is shown in Fig. 5. llt consists of a piece of thin flat steel B having two cutting edges E, and two raised integral tongues T, which are struck up from the body of theblade 1B and having re-entrant bends 10, and outwardly turned terminal portions 11, as more clearly foration 13.

This bladeis adapted to be used with each of the three. forms of holders illustrated respectively in Figs. 1 and 2, Fig. 3, and Fig. 6.

The blade B is fastened to its support by laying it flat upon the supporting surface S, the tongues T being positioned in the openings C, and occupying the position shown in Fig. 7. It will be observed that the raised hump P, when the blade is laid upon the fiat supporting surface S, lies in the elongated opening 13 of the blade. With the blade in this position, it is pushed longitudinally on its supporting surface. The terminals 11 of the tongues T pass outside of the undersurface of the supporting plate S, and further movement causes them to ride upon the underside of said supporting member and to engage that member, as shown in Fig. 8. The movement to this position necessitates a springing outward of the tongues T, and consequently results in a resilient locking action of such tongues upon the supporting member S. At the same time, the middle portion of the blade rides up over the hump until that member registers with the round opening 12 in the blade, as illustrated in Fig. 8, which acts as a lock for holding the blade firmly in place upon its support. This hump P and cooperating hole 12 are not absolutely necessary, since the blade will ordinarily be held with suficient certainty by the resilient force of the tongues T.

llt will be observed that the blade illustrated in Fig. 5 may be interchangeably used with any of the forms of support and the difi'erent handles shown. With the supports shown in Figs. 3 and 6 the blade is held in position so that either side may be used for shaving without change. With the support of Figs. 1 and 2 however only one cutting edge is in position for use, and in orlltlll der to use the other edge, the blade is taken 0d, turned end for end, and then engages the other pair of holes C or C, as the case may be, of the support shown in Fig. 1.

The blade may be provided with a downturned flange 15, at one end which makes it easier to slide it into place by pressure with the fingers This construction is shown in Figs. 7 and 8.

It will be apparent that many modifica tions may be made in varying the attaching elements. No attempt has been made to illustrate all of them. Instead of holes, loops of metal may be used to engage the tongues, and other equivalents. These are understood to be within the scope of the appended cl.
