water in pure form mixed with a treating substance purposes of or treating the mouth of the Accordin to the there s provided a dental appliance comprising a handle having means at one end for connecting same to a source of water and formed with a passagewa conducting the water therethrough to a location to the opposite end the said passageway terminating at said in a plurality of transverse openings forming a spraying head at said opposite end of the a separable brush unit disposed at the of said spraying head and in alignment therewith and with said and securing means for releasable securing said separable brush unit to said spraying head including a axial pin carried by the brush or spraying head and adapted to received in an axial opening in the other of the brush spraying said pin being formed with a and said opening being formed with an accomodating recess to prevent relative rotation between the The attachment to the handle may take several and in fact it is one of the advantages of present invention and that several different t es of attachments could 2 a fragmentary top plan view of a portion of the device of is a partly sectional view of the 1

end an The handle is provided with a generally designated adapted to control the flow of the water handle to the attachment Handle 2 is a passageway to a chamber which in turn is joined with passageway 14 terminating at the opposite of the within chamber 12 is a valve member 16 biased against seat 18 by coil spring Δ alve is connected to valve member 16 and extends through an opening in handle 2 where it terminates in a 24 exposed at the outside of the handle and adapted to be manipulated b It thus seen the flow water from passagewa 10 to passageway 14 is normally prevented by valve member but 22041 File 12478 Date it is desired to permit the flow of the is depressed by hand which causes valve member l6 to unseat from valve seat Attachment is formed with a passageway 26 leading to a plurality of transverse openings 28 which a spraying The of passageway 6 is whereby the water flowing therethrough will be forced out through the openings of spraying head An important feature of the present invention is the provis on of a brush 30 at the end of the attachment 6 proximate by spraying head In the embodiment brush is secured to 6 by means of a threaded pi or screw 32 carried by the brush and adapted to be threadedly received within a threaded opening formed at the upper end o attachment To hold the brush 30 in position when is preferably formed with a pair embossments at the end face thereof in contact with the end face of attachment and the includes a pair of recesses for accomodating these The backing or base of the brush 30 and the end face of attachment 6 are both preferably of plastic whereby the two contacting faces deform to enable the embossment 36 to enter into recesses 38 and to hold the in Pile Date It will of be appreciated that the foregoing structure of the contacting faces and attachment be reversed without changing the basic attaching arrangement An alter ative attachin arrangement is illustrated in 4 and 5 30 be formed with pin adapted to be received withi a corresponding axial opening in the end of attachment is formed with a itudinal rib at opposite adapted to received within corresponding recesses 44 and 46 in the As shown 4 and 5 recess 44 extends only partly through the wall the attachment and is tapered to receive its rib the latter being correspondingly tapered inwardly from the inner the outer the Recess extends all the way through w of the attachment forming a slit con igu of this securing means could also be reversed without changin the basic securing The attachment is preferably secured to handle 2 by means of an internally threaded sleev carried by the handle and cooperable with an externally threaded sleeve carried attachment or vice A sealing ring is interposed between these File Date As indicated the device illustrated is particularly useful as a dental appliance for rinsing or treating the is applied through conduit and is controlled by valve 8 to issue through spraying 28 and into the mouth of the The presence of brush permits the teeth or gums to be brushed or the water is dispensed through openings For it may be desirable to brush the teeth with brush and then use spaeying head 28 for rinsing the Or it may be desirable supply a treating material through spraying head 28 and at the same time to brush or massage the teeth or gums by the use of brush compartment 56 is preferably formed in the end face of handle 2 joining with attachment 6 so as to accomodate a treating substance if The treating substance ma be inserted within in the form of a pill or and it will be seen that as the water flows through passageway 14 attachement it carry along it some of the in It will be ma be fixedly secured to handle other types of othe than that specifically illustrated in may be to the end of handle It is to be understood that the embodiment of the invention is and that many variations applications of the or the several features may be made without departing from the spirit or scope
