INVENTOR. JACK J. LEVIN WM W AT ORNEY United States PatentO AUDIBLE TOOTH BRUSH Jack J. Levin, Baltimore, Md., assignor of fifty percent to Milton B. Silverman, Baltimore, Md.

Application December 12, 1955, Serial No. 552,543 2 Claims. (Cl. 15--105) This invention relates to larly to small brushes with a ing the teeth.

An object of the invention is to provide a new and improved toothbrush having its handle pivotally mounted in a housing containing means engageable by a part of the handle when the brush is moved in a substantially vertical direction across the teeth so as to produce audible sounds, such as musical notes and the like.

Another object of the invention is to provide a new and improved toothbrush of the above type, which is simple in construction, inexpensive to manufacture, and reliable and efficient in use.

For a clearer understanding of the invention and the objects thereof, reference is made to the accompanying drawing, wherein particular forms of the invention are indicated. This drawing when used in conjunction with the following description serves to illustrate the invention, its principles and the operation thereof, while the claims indicate the scope thereof.

In the drawings:

Fig. 1 is a plan view of a toothbrush looking at the bristle side thereof and provided with means by which sounds may be produced when the toothbrush is used in a certain manner, the sound producing means being shown partly in section and partly in elevation;

Fig. 2 is a longitudinal section taken along theline 2--2 of Fig. l, the toothbrush being shown mostly in side elevation;

Fig. 3 is a section taken and Figs. 4, 5 and 6 are detail views of modified forms of sound producing means.

Referring to the drawing and especially to Figs. 1, 2 and 3, the ordinary toothbrush comprises a head 11 at oneend having bristles 12 mounted on one face thereof, and anelongated handle 14 projecting rearwardly from said head.

In order to properly cleanse the teeth of a person, a toothbrush should be actuated in such direction that thebristles 12 move upwardly and downwardly over the teeth so as to effectively remove foreign matter that may be lodged in the crevices between the teeth. However, it is usually the custom when brushing the teeth to operate the toothbrush in a direction at right angles to the upwardly and downwardly direction referred to. Therefore, in accordance with the present invention it is proposed to embody with an ordinary toothbrush means so arranged with the toothbrush that when the same is operated in the desired upwardly and downwardly direction, pleasing sounds, such as musical notes, will be produced, and when the toothbrush is not operated in such upwardly and downwardly direction the sound producing means will remain silent.

At a suitable point adjacent the junction of thehandle 14 with the bristle end 11, the toothbrush is formed with anopening 16 for the reception of apin 18 carried by the forward end portion of asuitable housing 20.

toothbrushes, more particulong handle used for cleansalong theline 3--3 of Fig. l;

Thehousing 20 may be formed of any suitable material and may be of any desired size and configuration. In the present instance thehousing 20 is shown as being somewhat conical in form with thepivot pin 18 mounted in its apex orsmaller end portion 22 and with its larger end orbase portion 24 arranged beyond the extremity of thehandle 14.

So that the handle will be maintained in desired position within thehousing 20,washers 26 may be mounted on thepivot pin 18 at each side of said handle in the manner shown in Fig. 2.

Thehandle 14 extends through anopening 28 formed in theend portion 22 of thehousing 20, said opening having a suitable area to permit free movement of the handle therein, as will be understood.

Also, in order to maintain thehandle 14 properly aligned within thehousing 20, said handle extends through guide means 30 mounted within the housing and arranged at a suitable point adjacent the extremity of the handle.

The construction and arrangement of the parts is such that thehandle 14 is mounted within thehousing 20 for swinging movements in a substantially straight line to and fro for a limited angle at each side of the longitudinal axis of said housing. Theportion 24 of thehousing 20 may be closed by anend wall 32.

Mounted within thehousing 20 and spaced a suitable distance from theend wall 32, is abase plate 34 having a series ofsound producing members 36 mounted thereon and projecting toward the extremity of thehandle 14.

in the form of the invention shown in Figs. 1, 2 and 3, thesound producing members 36 may be reeds having various tone producing characteristics, said reeds being arranged substantially in a straight line on thebase plate 34 in the path of the extremity of the handle so that when the handle moves in the direction of the arrows, Fig. l, the reeds will be engaged by the tip of the handle and thereby actuated to produce musical sounds. will be understood that thereeds 36 may have such charthe position in which the in which thehandle 14 is pivotally mounted within thehousing 20, with the toothbrush in the position shown in Fig. 1, any rectilinear movements imparted thereto in a substantially horizontal direction will be ineffective to cause the extremity of saidhandle 14 to move across the row ofreeds 36. Consequently no sounds will be produced when the toothbrush is operated in such manner.

The exterior wall of the housing between theend wall 32 and thebase plate 34 may have a plurality ofholes 37 formed therein through which holes sounds produced within the housing can readily pass outwardly therefrom.

As shown in Fig. 4, in order to amplify the sounds produced by thereeds 36, theextremity 38 of thetoothbrush handle 14 may be provided with afinger 40. This on thehandle 14 in any desired manner and may be formed of any suitable mate For instance, thefinger 40 may be in the form of a spring hammer trip adapted to produce greater and more musical sounds when it contacts thereeds 36.

As shown in Fig. 5, in lieu of the series ofreeds 36, severalmetallic keys 44 may be mounted Within the halls suitable base 46.

ing, said keys being arranged to be engaged by the spring finger 46 of Fig. 4, to produce musical notes. The keys thekeys 44.

In lieu of thekeys 44 of the XYiOPhOI1 of Fig. 5, a series ofglass beads 50 of varying sizes and thickness strung taut with asuitable string 52, in the manner shown in Fig. 6, may be mounted within thehousing 28 in the path of thefinger 40.

From the foregoing, it will be seen that the present invention provides a new and improved toothbrush arranged to produce musical notes and other sounds many different forms. The invention disclosed will adequately accomplish the functions for which it has been designed and in an economical manner and its simplicity, accuracy and ease of operation are such as to provide a relatively inexpensive device considering what it will accomplish.

While a preferred form of the invention is shown in the drawing and described in the specification, it is not desired to limit this application for patent to this particular form, as it is appreciated that other forms of construction could be made that would use the same principles and come within the scope of the appended claims.

Having thus described the invention, what is claimed 1. A toothbrush arrangement, comprising, a head having generally parallel bristles for brushing the teeth and an elongated handle projecting from said head, a housing associated with said handle, the end of said handle opposite said head being positioned on the interior of said housing, said handle being pivotally mounted to said housing by a pin for movement about an axis which extends generally parallel to the direction in which said bristles project from said brush head, and means including a base located in said housing at the end thereof opposite said head with said bristles and having music elements mounted therein arranged in proximity to said end of said handle spaced from said head and adapted to be contacted by the tip of said handle when said handle is swung on its pivot to produce audible sounds.

2. A toothbrush arrangement, comprising, a head hav ing generally parallel bristles for brushing the teeth and a handle projecting from said head, a housing enclosing said handle, said handle being pivotally mounted to said housing by a pin for movement about an axis which extends generally parallel to the direction in which said bristles project from said brush head, and means including a base located in said housing at the end thereof opposite said head with said bristles and having music elements therein arranged to be contacted by the end of said handle remote from said head when said handle is swung on its pivot to produce audible sounds, said end of said housing containing said base having apertures provided therein so that the musical notes can pass from said housing.
