ROTARY TOOTHBRUSH Filed Feb. 27, 1967 United States Patent O 3,451,086 ROTARY TOOTHBRUSH Elbert B. Burgett, 2809 N. 3rd St., Flagsta, Ariz. 86001 Filed Feb. 27, 1967, Ser. No. 618,774 Int. Cl. A46b 13/02; F16h 21/26 U.S. CL 15--23 1 Claim ABSTRACT OF THE DISCLOSURE This invention relates generally to self powered toothbrushes. More specifically it relates to rotary toothbrushes.
A principal object of the present invention is to provi-de a rotary toothbrush which includes a shield over a portion of the brush so to prevent rubbing and irritating the tongue and other tissue of the mouth during -brushing operation.
Another object is to provide an improved rotary toothbrush which has a hollow handle containing a battery powered motor for rotating the brush, the ymotor being reversible in direction so that it may be used for :brushing both upper and lower teeth in an approved manner which is brushing away from the gums toward the tips of the teeth.
Yet another more specific object of the invention is to provide a rotary tooth brush wherein the Ibrush has a combined rotary and axial reciprocating motion causing more effective cleansing.
Other objects are to provide `an improved rotary toothbrush which is simple in design, inexpensive to manufacture, rugged in construction, easy to use and efficient in operation.
These and other objects will be readily evident upon a study of the following specification and the accompanying `drawing wherein:
FIGURE 1 is a perspective lview of a toothbrush incorporating the invention,
FIGURE 2 is an end view thereof shown in operative use,
FIGURE 3 is an electric circuit diagram thereof,
FIGURE 4 is a perspective view of a fmodified form of the invention, and
FIGURE 5 is a cross sectional View taken on line 5-5 of FIGURE 4.
Referring now to the drawing in detail, the reference numeral represents an improved rotary toothbrush according to the present invention wherein there is a handle 11 which supports a brush 12.
The handle 11 comprises a walled case 12 having a central compartment therein for containing an electric motor 13, a dry cell battery 14 or other -power source, a rheostat 15 and an electric switch 16, all in circuit; the switch 16 having a button 17 protruding outward of the case for movement between a forward position 18 a reverse position 19 and an off position 20 designated on the case. 65
The rheostat likewise has a rotatable knob 21 on the outside of the case for manual adjustment between a high and low speed position 22 and 23 respectively, also designate-d on the case.
A motor shaft 24 extends outward of the case end 25 and carries the cylindrical brush 12 at its end. A guard or shield 27 having a semi-cylindrical configuration covers a side of the brush, the shield being secured by screws 28 to the case.
In operative use, the brush is held against the teeth 29 and activated to rotate in a direction away from the gums 30, as indicated by arrow 31 in FIGURE 2.
In FIGURES 4 and 5, a modifie-d construction 32 is shown to comprise the above described structure and wherein the brush 33 has a longitudinal bare sector 34 Without any bristles 35. The shield 36 has a radially inwardly projecting, ldiagonally positioned comb 37 formed on its concave inner side 38, the comb 'having teeth 39. Each tooth has one longer and shorter side in the manner of saw teeth. A disc 40 is integrally formed on motor shaft 41, and a compression lcoil spring 42 bears at one end on the disc and at its other end against the case 43, normally urging the shaft outwardly. The shaft `41 `is mounted in the housing 11 in a manner which permits axial movement, that is, the shaft can move longitudinally of the housing a predetermined distance. This shaft can be provided with axially spaced stops to limit such 4axial motion (not shown).
In operative use, when the brush is rotating, the bristles rub against the diagonally positioned com-b causing the brush to move longitudinally toward the handle. When the bare sector 34 comes into alignment with the comb, the longitudinal pressure is released and the spring 42 returns the brush outwardly along the longitudinal axis thus resulting in a reciprocal longitudinal brush movement during the rotation thereof. This gives greater brushing activity.
Obviously sponge rubber -may be substituted for the bristles in this invention.
The novel features and the operation of this device will be apparent from the foregoing description. While the device has been shown and the structure described in detail, it is obvious that this is not to be considered limited to the exact form disclosed, and that changes may be made therein within the scope and the spirit of the invention.
I claim:
1. In a rotary toothbrush, the combination of a handle, a shaft extending from said handle and axially slidable in said handle, a cylindrical brush on said shaft and having a bare portion extending axially of the shaft, means on said handle to rotate said shaft, means normally biasing said shaft outwardly from said handle, a shield mounted on said handle and enclosing a portion of the brush, an abutment mounted on the shield and angularly disposed relative to the bare portion and adapted to Contact the brush and to exert axial force on said brush to move said shaft axially relative to said handle as said brush rotates, whereby the shaft is caused to simultaneously rotate and reciprocate axially providing effective clearing action.
