Ici. .i-176') Y This, invention relates to newl and useful irnprovements in anV interchangeable tooth brush. More particularly, the invention relates Yto a tooth brush having a handle with afrecessed head portion to receive a tooth brush refill, or a' massaging member rell, ora combination rell.

The dominant feature of the invention' resides in the manner in which thelreflls arereleasibly mounted in position. f l

In one formv of the invention a novel arrangement is proposed whereby a stern is removably mounted through the handle and engages one end oi the refill for releasibly holding the same in conjunction with stud and socket elements which l are mounted on the handle and reiill forholding the other end of the refill.

Still further the invention proposes a modiied construction in which the refill may be sup-v.

In the accompanying drawing forming a mate- I rial part of this disclosure:

Fig. 1 is a perspective view of an interchangeable tooth brush constructed in accordance with this invention.

Fig. 2 is a longitudinal sectional View of the v tooth brush shown in Fig. 1.

Fig. 3 is a perspective View of the reiill shown in Fig. 1.

Fig. 4 is a perspective view of the reiill shown in Fig. 3, but turned around. Y

Fig. 5 is a fragmentary enlarged detailed View of the stem shown in Fig. 2.

Fig. 6 is a fragmentary sectional view similar to Fig. 2 but illustrating a modified construc-` tion.

Fig. '7 is an elevational view of a rell adapted to be used in the interchangeable tooth brush.

Fig. 8 is another fragmentary sectional view similar to Fig. 6 but illustrating still `another ferm of the invention.

Fig. 9 is another sectional View similar to Fig 6 but illustrating another modification.

The interchangeable tooth brush, in accordance with this invention, includes a handle IQ having a head portion Ilia which is formed with a recess II to receive a tooth brush rell I2 which is illustrated mounted in said recess. A stem I3 is removably mounted through the handle and engages a`socketelenent.'lfsuchlas a niche, on thev other endvof the rell I2, 5 I "f The vreiill I2 'comprises a base section :i 6.3 sup- Y portinga plurality of bristles or massaging-lele".

The stem `I3'y is engaged through a 1 tube I8 which is xedly mounted'through the handle I lThe'outerrend-ofgthestern I3 is provided with a screw IS havinga head` portionZI) y by which the screw may be turned.` K'Ihe'screw I9 threadedly engages Ya-portionof the tube I8.

The inner endV of the stem I3,'indicated by reference numeral Ia, normally engages an aperture 2| formed in the end-of the refill l2.

l Figs.` 1 and 2 illustrate the toothbrush ready When it is desired to remove the refill." vl2 it is merely necessary that the head 20v be turned'to screw out the stem I3 a little way s o. f that the end I3a disengages from .the openingA for use.

This rell I2' has theusual base por- I tion IS formed with the openings I5 and 2I`in the end portions thereof.A Massa'gn'g elements I'I project from its top face.

In Fig. 6 a modifiedform of thefinvention is disclosed which distinguishes from the first form in the vfact kthat the stern I3 passes through the handle I0 instead of passing through a tube mounted in the handle as previously explained.

The screw I9 of the stem I3threadedly engages the rear portion of the handle I0. In other re-V spects this form of the vinventionfis similar to the previous formand like parts are indicated by the same reference numerals. Y

In Fig. 8 still another form of the invention is illustrated in which the reIill'IZa is4 provided with a series of apertures Zia along one end thereof. The stem I3 is adapted to engageo'ne.

ofthese apertures to hold this end of the refill projected a selected amount. The other end of the refill I2a is pivotally supported by a stud |48 which engages a conical socket |58` formed in. n The stud 14a is shown to be integral with the head portion I la of thev the end of the refill |25.

tooth brush. In other respects this form of the invention is similar to the previous forms.

A similar rell may be substituted, or a*V Y pivoted to a new selected position and held in this position by re-engaging the stem I3 with the aperture 2 la now aligned with it. s l

It is possible to adjust the angular inclination of the refill |2a to suit the requirements of the user as governed by the manner in which'the handle of the tooth-brush is gripped. Also, if the bristles l1 on the end of the refill |2n having the apertures 2|a wear away, it is possible to extend =,these bristles to cause the front ends of all of the-bristles to assume apposition parallel with the back of the brush.

In Fig. 9 still another form of the invention -is J disclosed which distinguishes from the prior form in the construction of the refill '|2b., This rei-lil is shown provided with a projecting stud I5b which engages a conical socket Mb formed in the adjacent portion of the head ma of the handle.VV
