useful Im rovements in Fountain Tooth-v brushes, o which the following is a speci- My present invention relates to improvements in fountain tooth brushes, such vas seti-forth and shank of` thetoothbrush, whereby al convenient and sanitary arrangement is provided. c

A further Object of the lnvention is the provision/.of an improved fountain tooth` `brush of the above described character,

which is compact, metal enclosed and protected, and'simply constructed of detach-A able parts to provide a, sanitary structure, in which the parts are readily accessible for cleaning purposes.

Other` objects and advantages will be apeparent during the course of the following etailed description:

Figure 9 is a cross-sectional -view taken on the line 9--9 of Fi ure 1.

In the drawings, w erein for the purposev of illustration is shown the preferredv embodlment of my invention, the letter'A designates a supporting casing of the improved tooth brush, detachably receivin a brush head B,- and a brush head casing adapted for positioning over the brush head B for the purposes of protection when not'using the toothbrush. The improved fountainv tooth brush is ladapted for use 1n connection with a collapsible tube D containing any -V approved dentifrice, preferably in'theform of paste.

The supporting casing of any ap'- proved "material,` either .ile-'xiible or rigid, l

A simulates 'somewhat the ordinary toothv brush and includes the hollow handle structure'lO, and the brush head receiving shank l1-` The -hollow casing 10 is preferably oval in cross section to provide a space 12 therein for ,receiving the collapsible tube D. l A lower section 13.0f the handle 10 isv rigid with thev tooth brush head-shank" 11, zwhilei an upper section 14 is hingedly connected -at one side 15 to the section 13. The side or cover 14 preferably comprises one half of the handle structure 10, and when closed is provided with a, projectingl portion 16 adapted for engagement upon a ridge 17 of the section 13.

The brush head shank 11I lis preferably integral with the section 13,-extending forwardly from the saine,` and provided with abore 20 leading from the interior 12 of the casing 10 lto communie te upwardly through a discharge port 21 ormed 'on the brush head seating surface Th'c brush" head seatmg surface is preferably flat, and provided upon the lextreme end of shanky 11.v ArchedA side anges 23 are provided upon eachvside of the seating'surface 22, and terminate short of the forward extension of said seating surface substantially as illustrated in Figure 4. The seating surface 22 projects rearwardly into the shank converging' pocket 25 to receive thenzzle 29 of the container D, 20

and .which nozzle is ordinarily provided -upon dentifrice containers oflthe collapsible tube' type. In attaching the tube D to intol the handle 10.

the socket28,l when such socket is disposed in parallel alignment with the handle 10, some diiliculty is encountered ,in properly screwing the same in place, due to the fact that'the collalpsible container- D cannot be readily rotated to effect such screwing, whenj the same-is. positioned immediatelyon the handle 10. :'lofacilitate attachmentof the container, D, the socket 28 has accordingl' been formedupon the'supporting casing having the axis thereof disposed upwardly at an acute antgle with respectl to the longitudinal axis elining the handle 10. `It is preferred that the socket 28 have its open' ing, and axis facingthe cover .portion 14 of the'handle 10, substantially as illustrated in the drawings. An observation lof Figure 3 of the drawings will show the method of y attaching the containerD in position in the j tube IDadjacent its Vnozzlel29, this distortion being' easily .effected due tothe col- The tube D' socket structure 28, and the-` purpose for which' such socket structurel has Ibeen pro.

vided. The socket 28 is preferably formed" integral with the shank 11 and projects The brushihead B is of special formation and comprises the ,base 35 formed of bone, celluloid, hard rubber, or any approved material, said base 35 having the ordinary tufts 36 mounted therein for cleansing the teeth. The base 35 is provided with longitudinal grooves 37, in eachside thereof,iand preferably centrally of said side; `said grooves 37 being provided for the purpose 'of slidably receiving. the arched guidev flanges 23 of-the shank 11. A reduced and tapered extension 38 is provided, 'rearwardly upon the base 35 of the brushhead B, for the. purpose of disposal within the pocket 2,5v formed'in the brush head shank 11. Thus in assemblingthe brush head B, to

` slid rearwardly from the forwardend 26 of -said shank, with the arcuatev guide flanges v 23 disposed in the side grooves 37 of the base 35. Said brush ,head B is manuallyv pushed rearwardly. until theextension 38 is disposed within the pocket 25, substantially as illustratedin'Figure 3 of the drawings, and t'hus rigidly and securely connectin A.'

he brush head casing A(l isprovided for disposal over the brush head B for the purpose sof protecting' the tufts 36 thereon,

when the improved fountain tooth brush is not in use. The casing C is preferably rectangular inl formation, having the rear end-41thereof o ento permit ready disposal of said casing (l) from the forward part of theifountain brush, and over, the tufts 36.` n

Thesides 42 and'forward end 43 ofthe casing Chave their lower edge or marginal portions. 44 bent outwardly and inwardly, for

attachment to the sides of the shank 11 and the arched guide flanges 23,. to prevent disconnection of said casing U. v

In operation, when using the improved fountain tooth brush, the cover 14 thereofy is swun upon the hinge- 15 to openi-the hollowA .hand elO, the collapsible tube of dentifrice B is-then inserted in axial'` alignment with -4 the socket'28, and thenozzle 29 of lsaid. tube D is then screwed into the socket 28 until a thel same 'is insubstantially the position illustrated in Figure 3. njthis position the user of the tooth brush presses the'Qtube D downwardly into the 0pening`12 of the rigid section 13 andI this necessarily distorts the lapsible nature of such tubes. now assumes the position jas illustrated in Figure 2, and the cover or hinged lid 14'of the handle can then be closed and locked. When a person desires to usethe device, the

cover C is removed, .the section 14 is unlto apply tubes of various size to the same fountain tooth brush. I

In'the form illustrated inFigure 5 of thc drawings, the nozzle Yconnection 45 is provided with a tapered snout 46, adapted for reception upon the inwardly tapering seat 17'provided in the bore 48 of shank 49, said in the ilo" l seat 47 being disposed to communicate with the opening '49, and provided in the handle structure 50. The nozzle connection 'is provided with an int '.r n'a1ly screw threaded bore fora portion of its length to receive `vthe nozzle 51 of the tube D ina detachable size as to the lnternally screw threaded bores" for reception of the various'nozzles 51 for different sized tubes D. The axis of the tapered seat 47 is disposed atan acutangle to the axis ofthe handle and consequently the nozzle connection when inserted therein has .its axis similarly positioned. In al1- other respects, the im roved fountain tooth brush illustrated in Flgure 5 is the same as that above' described.

As a further modication, a swivel type i of nozzle connection 55 can be provided,

the same having a forwardly yoverlapping annular iange 56 adapted to grip an out- Y wardly extending annular flange 57, vprovided upon a nipple 58 extendinginto the pocket'59 provided in the handle structure :60. The nipple 58 i's preferably formed tooth brush', the operator inserts 'the collapintegral upon the shank 61 of the improved means of a borel leading from said handlev into s aid brush head, ther axis of the portion of said bore adjacent the handle lbeing disposed at an acute angle to the longitudinal axis of said handle, and a nozzle connection for detachably receivingthe feed end of, said container and adapted for detachable reception in the portion vof the bore of said tooth brush adjacent said handle, the angle of said bore to the axis of the handle being such rangement/of parts may made to the i that the closed end of a container seated by means of said nozzle connectionin said bore will project outside the outline of the handle mani ulating the same."

and which is provided for the purpose of facilitating entrance of the ctube D inl the pocket 59. In using this type of fountain sible. tube D throu h the opening provided by swinging back t e cover 65 ofthe handle 60, and the swivel connection 55 is--rotated upon the nipple 58, at the same time-.applying the nozzle 64 into the socket ,openingI 63., of the swivel 55, and upon rotation of said v'swivel v55 the nozzle 64 will be secured' j thereto.
