Specification of Letters Patient.

Application flled' October as, Serial no. 393,686.

To all whom it may concern:

Be it known that we, ROBERT SAMPSON and ROBERT WILLIAM SAMPSON, subjects of the Kingdom of Great Britain, residing at Montreal, Province of Quebec, and Dominion of Canada, have invented certain new and useful Improvements in Lather-Rubbers, of which the following is a specification.

Our .invention relates to devices for lathering the face to prepare it for shaving, and

consists in certain improvements whereby the efficiency and desirableness of the lather rubber are materially increased.

Our improved lather rubber is preferably made out of rubber, and embodies an imper- --forate rubbing face provided upon its back with suitable means by which it may be grasped orattached to a handle, as of" a shaving brush.

In the drawings Figure 1 'is a side elevation, and Fig. 2 a bottom view of our device;

Fig. 3 is a vertical sectional view of the same applied to the handle of a shaving brush; Figs. 4,5 and 10 are bottom views and Figs. 6, 7, and 11 their respectively corresponding vertical sections of modifications in the face of therubber; Fig. 8 is a vertical section of another similar modification; and Fig. 9 shows a modification of the neck or handle part of the rubber.

fiimilar letters of reference designate similar parts in all the figures.

We have shown our device as .provided Wltll an lntegral, tubular shank A, which serves as a handle and which may also be sl pped over a rigid handle, as of a shaving brush, as shown in Figs. 3. and 9. The shank may be either straight as shown at A,F1gs. 1,3, 6,7,8 andll, or it may be bent, for mstance as shown at A in Fig. 9, as may be found most convenient in use; and'it carries the face B, which is in the form of an imperforate disk, preferably concavo-convex, and provided with amarginal rim or flange C, and projections asl the. annular flanges D D, in Figs. 2 and 3, transverse ribs E E, as in Figs. 'and 6, crossed ribs F F, as in Figs. 5 and 7, conical orteethhke projections G G, as m Fig. 8, circular flanges H H as in Figs. 10. and 11, or other suitable projections or indentations.

The use of a lather rubber having an imperforate concave face with a central, flexible Web portion increases'the cupping efll-- ciency of the lather rubber, permits the centralas well as the marginal portions of the rubbing face to operate upon the skin, pre-- ventsthe lather from working up above the rubbing face and also renders practicable the application of both a firm pressure and a yielding pressure upon the skin. For it will be seen that when the handle is inserted in the sleeve, as in Fig. 3, the central imperforate web portion 0, of the rubber will be reinforced by the rigid backing of the handle so that, if suflicient pressure is used to bend up the flexible edges of the face B, the cen- -Patented Nov. 24, 1908-.

tralportion of the arubbing face may be brought firmly against the skin, thus producing a yielding marginal pressure and an unyielding, central pressure with the rubber. When a handle having a rounded endis used,the central web of the rubber may be pressed down into a convex form, as shown in Fig. 3, which will closely resemble the rounded ball of a finger end, and which will give effects similar to those produced by finger rubbing, but without the dangers of contamination incident 'to direct contact with the human fingers. So, also, in the modification shown in Fig. 9, the elbow of the sleeve where it is reinforced by the end.

of the handle, as indicated by the broken line, will form a centrally convexed massager, which may be used alternately with the face B if that is desired. 7

This device, it will be observed, can be applied to the handle of the ordinary shaving brush. Because the rubbing device is athacked to the handle of the brush thecombined device. can be turned promptly in the hand to use either part as may be desired.

This is an important advantage because lather dries quickly, and much inconvenience and loss of t me results where it is necessary to stop to perhaps first find and then separately pick up .t e parts.

We areaware thatthedetails ofour appliance may be modified without departing from the spirit of our invention.

Having thus described our invention what We claim and desire to secure by Letters Patentof the United States is As an article of manufacture, a lather rubber for application to a shaving brush comprisingb in combination an imperforate, fiexi 1e we having a massaging or rubbing surface at one side consisting o a plurality of concentric ribs or flanges diminishing in height from the outer flange inwardly, and


a socket portion projecting from the opposite side of the web adapted removably to receive and engage the handle of the brush. 15
