Projecting from the forward face of such character by means of which a tube or of the base member 1, in spaced relation to the 5 can of dentifrice and a plurality of tooth curved bottom 4;, are a pair of brackets '7, the B0 brushes may be conveniently supported in con central portions'of which are arranged in spaced nection with a rotatably mounted time glass relation to the forward face of the base member adapted to operate for the length of time re- 1 in order that the handles of tooth brushes, quired to properly brush the teeth, thereby resuch as 8, may be inserted between the central ducing the likelihood of the teeth being neglected portions of the brackets and the forward face 65- thrcugh a mere perfunctory brushing thereof. of the base member for supporting the tooth A further object of the invention is to probrushes.

The shown an embodiment of the invention, but it time glass 10 is slightly less than half filled with is to be understood that the description and a suitable material such as fine sand, indicated drawing are to be taken as illustrative and that at 17, and the restricted central portion 18 of the invention is intended to be limited only by the time glass is of appropriate diameterto per- 90 the scope of the claim hereunto appended. mit the material 17 to flow through the restricted In the accompanying drawing in which like portion 18 in approximately two minutes, the numerals are employed to designate like parts time ordinarily required for the proper brushing Referring to the drawing in detail, the nutimer, the support 9 should be swung around its meral 1 indicates a verticallly disposed support pivot 13 to position the indicia 19 at the upper or base member which is of flat formation and end of the support, and the brushing operation formed intermediate its side edges with an upof the teeth should continue throughout the wardly projecting portion 2 provided with an entire length of time necessary for the material 105 opening 3 for the passage therethrough of a 17 to flow from the upper end portion of the time suitable holdfast device by means of which the glass to the lower end portion thereof.

The base member 1 is formed with a the support 9 should be again swung on its pivot curved bottom 4 which terminates at its free to position the indicia 20 at the upper end of the 10 support in order that the material 1'7 may again flow through the restricted central portion 18. The indicii 19 and 20 serve as reminders that the teeth should be brushed twice a day and will always correspond with the time of day after the teeth have been brushed at the proper time.

The support 9 for the time glass 10 including the ears 14 forming a part of the support, is of slightly resilient material in order that the time glass may be conveniently removed therefrom if desired, and in order that the time glass may be readily replaced in case the same should become broken.

It is thought the many advantages of a dental rack and timer in accordance with this invention will be readily apparent, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the size, shape and arrangement of parts may be resorted to, so long as such changes fall within the scope of the invention as defined in the appended claim.

What I claim is:

In a dental rack and timer, a vertically disposed stationary support having an opening intermediate its ends, a revoluble suspension'element permanentlypositioned against the front of said support and formed of'a hollow body part of uniform cylindrical cross section atany point throughout its length, said body part open at its front from end to end, said body part being formed centrally of its back with an opening registering with the opening in said support,

means extending outwardly from said support,

through said registering openings and connected :to said body part and support for revolubly suspending said element and for connecting the latter against the front of the support, and a pair of opposed resilient coupling arms converging towards each other, integral at their rear ends with and extending from the ends of said body part, said arms being of materially less width
