My invention pertains to a device for cleaning the spaces and cavities between the teeth and for extracting food' particles, food tissue or the like from between the teeth. My invention relates particularly to a highly efficient and sanitary instrument or holder adapted to hold a flexible band or thread adapted to be inserted between the teeth, said band or thread being easily and quickly replaceable. I 1
An object of my invention is the prov sion of a highly serviceable holder which has means whereby an ordinary flexible band or thread may be quickly secured thereonto provide a device for cleaning the teeth, and which band may be quickly removed if broken or unclean, and replaced.
A further object of my invention is the provision of an eflicient and sanitary holder for an elastic rubber band having means whereby a portion of said rubber band may be held in stretched and projected position with respect to the main part of said holder and-pep mitting convenient insertion and movement between the teeth. 3
Other and further important objects of this invention will be apparent from the disclosures in the specification and the accompany-' ing drawing.
This invention '(in a preferredform) is il-, lustrated in the drawing and hereinafte -r more fully described. I Y

As shown on the drawing:
The reference numeral '10 indicates a sub stantially rectangular body of my preferred device which is preferably made 'of'a hard rubber, bakelite, or other material'capable of being molded and which has a slight degree' of elasticity An arm 11 is formed integral with the corner of the body 10and extends radially and at an obtuse angle to the twoadjacent sides of the body. V
I An arm 12,-which is formed integral with the body 10, extends from the corner of said body adjacent the arm 11, and comprisesa relatively short portion which is parallel to thelonger'sid'es of the body 10,' and an outer angular integral portion which is substantially parallel to arm 11. I a
As clearly shownin Figs-2,4 and 5, transverse grooves 32 are formed on both theopposite flatsides of the body 10 from which 55 I arms 11 and 12 project, said grooves connecting with notches 13 and 13f0rmed in op posite edges of said body, as shown in Figsi land 2. f Said notches 13 and 13' are made so asto"formxshort-studs 14 and "15 with portions of arms 11 and 12. A short recess 33 isformedadjacent each of the notches 13 and 13 and longitudinally on each of the arms 11 and 12 so as'to provide means where-' i Y A short slit 16 is formed the side of the u arm 11 at the end thereof, as shown in Fig. 3, and a similar slit 17 is formed in the side'of the outer portion of arm 12 'preferablyonthe same side-as the slit 16. a I
My tooth cleaner as above described is-constructed particularly to quickly and efficient-.7.
and about the ends .of arms and 21 in the l have removably mounted thereon a rubber t the teeth, and further, such elasticity pre serts the device too far,
band 18 in the manner shown in Fig. 1. rubber band 18 is first wound: around the. grooved side of the body 10 two or more times, after which the free ;loop ,portion which is retained in the fingers is inserted .in slits-16 and 17 of arms'll and .12 respectivelyjso that the. portions of-the rubber band lSjwill liealong the outer edge of said arms, and a slightly stretched portion will extend from oneto the other of the arms 11 and 12, V as clearly-shown in Fig.1. i
. Eachform of my tooth cleaner is the mannershown in Fig. 10, the devicebeing held between 't-hethumh and forefinger so that armsll pointseither'upwardly or down.-
wardly, depending upon-whether the upper or lower teeth are being cleaned. The cleaner is'inserted so that the shorter arm'll is'outside the mouth while the longer arm is-inside the teeth, the taut portion of the rubber band being-inserted between the teeth and pulled out one or more times. As-the rub-. her band is withdrawn it will carry with it food particles. and; other-matter which has lodged either between or onthe frontor back of the'teeth. The elasticity. oftherubber band permits turning the tootlrcleaner when the rubber band is between the teeth so as to.
cause portions of said rubber band to removefood particles from the front ,orback 'sides'of;
vents cutting of the gums when the user int as it willmerely stretch and bend. r v V The'rubber band may be quickly and easily replaced. in: the i manner 1 'afore-described, thereby-insuring a sanitary cleaner at all."
times. a v v T Fig. 6 shows;a modifie d form of my tooth cleaning device similar to'the afore-describ'ed preferred formexcept in that it comprises 1 an elongated U-shapedmember 19 terminat-l ing in one angularly projecting arm 20 and a longercurved arm 21, said'armsbeing substantiallyparallel. The arms-20 and :21 ha v ingl side slitsv 22 and 23 respectivelyjinthe;
ends thereof-which are similar- :to those de-f scribed in my preferredformm 1 i The arm 20.curves inwardlyof the outer edge of the integrahportion' of the U shaped member 19, as shown in Fig. 6, and a notch i 24 isformed' in the outer edge of said arm opposite saidinwardly curved portion and substantially perpendicularly to the outer portion'ofsaid arm 20, thereby forming a manner shown' in Fig. 6 and so that the portion between said slits will be slightly stretched.
. Fig.7 shows asecond modified form of my device embodying a cleaning device similar to that shown in Fig-6 except thatthe U- shaped member 2'Z,-which has--an annular groove 82", notches andslits similar to those previously described, is comparatively short,
and the connecting portion thereof has a peripheral apertured ear 28. Said 'U-shaped member is hingedly pivoted to theopposite walls ofa relatively thin casing29 by means of a short rivetBO which passes through said apertured ear and is secured in apertures in 'saidwalls. The casing 29 has one open edge and is ofa 'si-Zetto convenientlyreceive the U sha'ped member27 when it is turned'on its pivot to the position shown in Fig. 8, thereby providing a casing which will keepthe tooth cleaner olean'and sanitary,-particularly when carried in a pocketl' Aninwardly extending stud 31 is secured on the inside of one of the walls of casing 29 and near the open edge thereof, the longer arm of the U-shaped member' 27 beingadapted to depress said stud to push the casingwall outwardly, whereby the tendency of said wall to maintain normal position will cause said stud to press again st.
said longer arm to hold the tooth cleaner within the casing.
