UNITED STATES FRANK MCLAUGHLIN, OF PHILADELHIA, PENNSYLVANIA.

Y LATHER-BRUSH FOR POVDERED SOAP.

Application filed September 5, 1919.

To @ZZ whom t may concern.'

Be it known that I, FRANK MCLAUGHLIN,

.a citizen of the United States, residing at 2325 N. 33rd street, Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Lather-Brush for Powdered Soap, of which the following is a specification.

My invention relates to lather brushes which are intended for use preparatory to shaving.

The purpose of this invention is'to provide a narrow opening extending deeply into the brush which will receive and to some extent act as a measure for the quantity of soap powder which it is intended to use and from which the soap will not spillV readily but will be distributed throughout the brush.

A further purpose is to provide a brush and receptacle handle with coacting retaining parts withinv the receptacle and withV quick and handy release mechanism therefor capable of operation by the hand holding the receptacle handle.

A further purpose is to secure the brush in position by a catch and provide laterallymovable release operating mechanism, convenient for use by the hand holding the receptacle handle.

A further purpose is to provide a brush and soap-powder-holding receptacle-handle having a large front opening normally closed by a removable brush, which handle is readily cleaned and which is substantially free from lodging places for dirt and vermin.

A further purpose is to provide for quick drying and ready cleansing of a lather brush.

Further purposes wilt appear in the specification and in the claims.

It has been thought best to illustrate this invention by several diii'erent forms of brush-holding mechanism characterized by snap or latch holdingdevices within the re- Y ceptacle handle and all but one by lateral movement of the finger contacts of the release mechanism; though it is recognized that other forms of operation will come within the broader claims of this application, and that many other modilications securing lateral movement of the finger contacts will Vbe suggested to the'designer by the forms shown. The selected forms have been chosen from a large number because Specification of Letters Patent.

Comparatively little difficulty has been met in adapting brushes and brush handles for the use of a fluid or plastic soap, but their weight is against them and it has been found difcult to clean them properly without unduly wasting the reserve supply of soap. However, quick, easy, convenient and cleanly application of a powdered soap to handle container and removable brush use have presented greater difficulty but are attained in the various forms disclosed herein.

Taking up first the form shown in Figs. 1-11:`

I provide the brush 2O with a hollow center as shown at 21 extending clear to the base of the brush to give access for cleaning the brush and light and air for drying it and keeping it clean. The opening may conveniently be made of such size as to hold a reasonable charge or quantity for the lather required for a shave.

The open center protects against vermin which seek the dark, damp parts of the brush and fatten on the soap which too often lodges there. l

The bristles are held in the annular groove between the sides 22, 23 of a holder 24, closed at the center at 25 and flanged at26, to close the open end of the container handle 27.

Whether the interior wall 22 of the bristle-holding brush socket shall be straight, as in Fig. 1, or must be tapered, as 24 in Fig.

' 1il to give the center Aopening will depend `upon-the character of bristles used. The

method of retention also willvary, some being set in rubber; some clamped, as between the inner flange 24 and an edge, such as 28 upon the outer flange,'etc.

Upon the interior of the brush holder'is secured a plug 29, terminating in a ball or other projection 30. It may be held frictionally or sweated'in (as in Fig. 1) or may beprovided with projections 31 limiting its movement and retained by a screw 32 (as Vin Fig. 1a) or by any other suitable means.

In'the form of Fig. 12L the 'head may be tapered tospread or to assist in spreading the inner iiange, to spread the bristles more at 21.

At lthe rear end, the container handle is terminated by a base flange 34 upon which the brush is adapted to stand, and is sealed Y by a closure 35. This is held in position. by

one or more bayonet joints 35 Where the `base of the brush and the socket into which it fits in the open end of the handle, are cylindricahit is quite desir- 'able that the'sides'do not come into contact throughout much of the circumference because of sticking from the soap powder. I therefore prefer to have ribs 33 of contact I only,'as in Figs. 4 and 7 and may use the The support 36 is circumferentially cut at 38 and the cut parts are turned inwardly in theform of ears 39, whichare apertured at 40 to receive lateralpivotal projections 41 upon gripping arms 42. These are provided v`with fingers'43 at their forward ends for engagement with and retentionl of the ball 30, and `with'apertures 44 at the .reverse ends to pass aV rod 45./ A Y Y .The rod carries a spacing ,compressionV i spring .46,tending to separate the ends 47 of these fingers, andV tubular finger-pressed plungers 48 whose ends 482 are intended to engage with'the outer surfaces of the ends of the gripping arms.

`The space within the receptacle is filled with powdered soap and each time that the brush. set .down upon` .the Y `base, 34, this soap is settled to the rear of the container handle.

In operation The brush is moistened and its handle is held in one hand, say the right hand with the forefinger and thumb engaging and pressing the ends of the iinger contact members 48. This releases the catches from the ball 30. At the same time the brush end, now free, is withdrawn by the left hand from its seat in the end of the handle and is turned until Vthe bristles eX- tend in an upward direction. A quantity of soap powder is then poured from the container handle, filling the opening in the brush. liththe open end of the receptacle directed upwardly, the brush is now inserted in position and is put into place, as in Fig. 1, the finger-pressed members 48 being pushed together to open the catches, while the brush is inserted. The brush isthen ready to be applied in producing a lather.

In the form shown in Fig.V 11 the parts are similar except for the supporting sleeve and the'catch mechanism by which the ball terminal of the brush is held.

The pivoted catch parts v are supported upon a frame 49 instead of upon arms inwardly projected from the sleeve 36. The catch members 42Y are providedwith apertured pivotal ears 50 bent infrom the sides and with cuppedterminals at 51,*gripping the ball.. Thespring 46surrounds the Ypin 45 and is of torsional form with the rsame effect, in that it opposes release of the catch members when the. finger contacts 48l are pressed. l j l Y i ln the form shown in Fig. 12 the sleeve 36 supports leaf springs 52 embodying the functions ofthe armsand the springs and whose ends 53 spring outwardly into an inwardly-directed flange 54 carried by the base of the brush member. The springY catches are released by laterally (radially) movable pins 55 secured Vto the springs at one end and carrying heads 56 at the other.

In theform shown in Figs. 13 and 14, the rearv end of the sleeve 36 supports a transverse strip 57, which maybe integral with it as shown, and from whose edges ears 58 are turned. Pins 59 in these ears form pintles` for thejarms 42? pressed apart by' spring 462 so that their ends 53 engage anV inwardly turned flange 54. i

In the form shown in Figs. 15,16 and16a,

Y the finger contacts 48 terminate at their inner ends in annular, reversely-turned cups 60, whose hubs 61 extendradially for engagement bythe' fingers. The hubs are bored to receive a pin l62 aboutJwhich springs 46? ts, and are counterboredY atx634 for screws Y 64,l fitting into the lpin and against the hub; Each of the cups engages with an inwardly-turned prong 54 and can.

be,V released ,from it by pressing the rfinger contacts toward each otheras in the other` figures.

Because the fastening device requires thatthe brush be placed in a particular position, to bring the prongs in line with the cups, the brush base and receptacle seat thereforv at the end of the holder are keyed, as shown at in Figs.` 1G and 16a.V f

In the form shown in Fig. 18, the clamping devices or catches 52', are formed of spring material and are terminated b anges 66, such that by pressure the ball can be forced between them and they will snap over it. The ball can also be pulled out from between them when it is desired to withdraw the brush.

In the form shown in Fig. 18, a single linger contact 67 is apertured to slide upon a pin 45 against compression spring 464. It carries a prong 43 to pass through an opening in a strip 29 secured to the back of the brush.

In either case the finger contact is fiattened and is guided against turning by the walls of the container through which it passes.

In the prong form the back of the brush and the container are keyed to present the opening in the strip. The prong is tapered to tighten the brush within the handle.

It will be evident that the catch or fastener is protected within the container in all of the forms and lies back of the zone of engagement of the brush base with the mouth of the container, so that any tilting pressure against the brush or brush base will be resisted bythe catch acting through the leverage which this rearward position of the catch provides.
