Figure 8 is an end elevational view of a still further modiiied form of the invention in which a bristle brush is substituted for the applicator roller shown in the previously described iigures, and

Figure 9 is an end elevational View of still another modied form of the invention which is similar to the form shown in Figures l to 4 inclusive with the substitution of an agitator roller for the sinuous or helical wire agitator employed in connection with the form of the invention shown in Figures l to fi inclusive.

In the drawings, and more in detail, attention is first directed to the form of the invention illustrated in Figures l to 4f inclusive wherein for the purpose of convenience of illustration there is shown a safety razor of conventional design generally designated 5 upon which the lather applicator generally designated is adapted to be removably attached. The safety razor 5 may be of any well known make and the type illustrated includes a handle 1 having a knurled hand grip portion and an internally threaded bore il at one end thereof for receiving the correspondingly threaded stud 9 of the blade clamping cap iii. A guard II is received on the stud 9 and the comb edges or ends I la of the guard are directed away from the cap i to provide a rounded surface on the ends of the guard teeth and eliminate sharp points, The blade i2 likewise of conventional design is held between the cap IIB and guard II by the clamping action of the handle 1 and stud 9.

The lather applicator includes a base plate I5 of a size and shape to be received beneath the guard II with the side edges thereof abutting the downwardly turned guard teeth IIa. The

base plate I5 is of a length substantially equal to the length of the guard II, and is provided with a central opening I6 adapted to accommodate the stud S when the plate i5 is in position as shown in Figure 2. In addition, openings I1 are formed in the plate one on each side oi the opening I6 to accommodate correspondingly positioned blade centering pins usually carried by the cap Il] on certain types of safety razors.

The openings I5 and I1 are connected by longitudinal slots I8 which are arranged such as to adapt the device to various other types of safety razors now on the market. Formed integral with the base plate I5 on one edge thereof adjacent each end is a bearing loop I9, between which is supported a pintle 2D which extends along the underside oi' the base plate when the assembly is in position as shown in Figures 2 and 5.

Hingedly connected to the supporting plate I5 is an applicator roller frame 22 having formed intermediate its ends a pintle loop 23 which projects into a cut-away portion 24 of the base plate I5 and encircles the pintle 20. rPhe loop 23 terminates in a curved extension 25 which is adapted to be engaged by the finger of the user when the lather applicator is being manipulated to apply lather to the face and said curved projection is also adapted to form a stop for the hinged frame 22 when the device is used for applying lather and simultaneously shaving.

Formed on the frame 22 is a pair o roller supporting arms 26 arranged one adjacent each end of said frame, and the free ends of each of the roller supporting arms 26 are provided with bearing openings for receiving the ends of a roller supporting shaft 21. An applicator roller 28 is supported by the shaft 21, and said roller is preierably formed of a resilient yielding sponge-like material such as sponge rubber.

Also mounted on the hinged frame 22 and supported between the arms 26 is.a sinuous or helical bar 30 which has its ends received in openings in the roller supporting arms 26 and aiflxed thereto. The bar 30 is adapted to contactually engage spaced apart portions on the peripheral surface of the roller 28 to create foam by the frictional engagement of said bar. As illustrated in Figure l the bar 30 is of undulating shape and arranged so that spaced apart portions will frictionally engage the peripheral surface of the roller 28 during rotation thereof and create a foaming action so that an ample supply of lather will be formed on the peripheral surface of the roller for being applied to the face of the user.

In operation, the base plate I5 is affixed to a conventional safety razor by being attached as shown in Figure 2 such that the linger projection 25 extends in a direction beneath the guard and cap of the safety razor. After the lather applicator has been thus applied to the safety razor a lather solution formed of soap and water is applied to the roller 28 either by immersing the roller in the solution or coating the same in any suitable convenient manner. The handle of the safety razor is then grasped by the user and the razor and applicator are manipulated as shown in Figure 3 to apply a lm of lather to the users face. The device is moved to and fro with the roller in facial contact so that the undulating rod 30 will produce a sufficient amount of foamy lather to soften the beard.

During the lathering operation the forenger of the user is pressed against the iinger projection 25 to hold the applicator roller 28 in its extended position as shown in Figure 3. When the beard has been sufficiently wetted and lathered, the roller supporting frame 22 is swung to the position shown in Figure 4 so that the finger projection 25 engages the neck of the handle 1, ln this position, the safety razor 5 can be used for the shaving operation with the roller 28 moving in advance of the cutting blade I2 so as to apply lather additionally and simultaneously cause the skin surface in advance of the razor blade to be maintained in a semi-stretched or taut position. Thus, the razor will cut the hair in closer relationship to the skin surface and produce a smooth and close shave. It is to be noted, that during the shaving action, the roller 28 also produces a massaging effect and kneading action which enhances the appearance of the user and creates a stimulating eiect upon the users face.

When the user has nished shaving, the varous parts of the razor may be removed and. the roller applicator likewise removed to facilitate cleaning by rinsing the roller in much the same manner in which the safety razor parts are rinsed after use.

It is to be noted that when the applicator roller 28 is in the position shown in Figure 2, the frame 22 engages the guard bar IIa of the guard II 2gsm-sse guard bar Ila. InJ the-other position as shown in Figure'v 4 whereinthe applicator roller travels in advance of the safetyrazor during shaving, the finger projection 25 engages the necked-inportion ofv the handle and provides a stop for limiting swinging movement of the frame and roller in an opposite direction.

In' themodifed formk of the invention shown in Figure 5,.the safety razor 5a, includes a handle lo' as well as a cap'laand guard 'da of asliglitly modified construction. The blade 12a is clamped between theguard 3 la, and theeap by the threadedstud 9a in muchthesame manner as described is provided adjacent its ends with depending lugs 32a having4 bearing openings 33a for receiving a pintle pin 34a; The applicator is identical to the applicator 6 shown in Figures l to l and includes a frame 22a having a central projection 25a which is curved and looped as at 23a to surround the pintle pin 34a. An extension 29a is formed on the hinge pintle loop- 23a and terminates in a finger engaging stop similar to the stop 25, Figures 1 to 4 inclusive;

The frame 22a is provided with roller supporting arms 26a having a shaft 2?@ for supporting the yielding sponge-like applicator roller 28a which as pointed out in Figures 1 to 4 is formed of sponge rubber or similar porous material. Also supportedv between the arms 26a is a sinuous or spiral rod 30a which is' similar to the sinuous 30 shown in Figures 1 to 4i, and produces the same agitating action to create foam on the peripheral surface of' the applicator roller.

In the modified form of the invention shown in Figure 6, there is provided a base plate [5b having a central opening lh which is similar to the base plate shown in Figures l to 4', and is provided with bearing loops adjacent each end i.

(not shown) for accommodating the ends of a pintle pin Zlib. The applicator is likewise similar 'to that shown in Figures l to l and includes a frame 22h having a central projection bent as et 231i to form The .free end ofy formed on the frame and are provided adjacent their ends with bearing openings for supporting a shaft 2lb upon which the sponge rubber plicator roller-28h 1s mounted.
