Description

Oct. 1, 1963 L. J. BENICK 3,105,254
BRUSH ADAPTER FOR ELECTRIC RAZOR- Filed April 17, 1962 2 'WW m LEONARD J. BENICK INVENTOR ATTORNEY 3,105,254 BRUSH ADAPTER FOR ELECTRIC RAZOR Leonard J. Beniclr, 313 Trappa Road, Baltimore 22, Md. Fil d Apr. 17, 1962, Ser. No. 188,223 3 Claims. (Cl. 15-22) This invention relates generally to brushes and more particularly it pertains to a brush actuating adapter for electric razors.
The electric razor is a well developed and widely available household article. It is proposed to expand its utility by employing the drive mechanism and motor to power a compound motion generating mechanism for actuating a brush. By merely exchanging the razor head with a brush head, it is thus possible for one to conclude shaving and immediately proceed to motor-brush ones teeth.
Accordingly, it is an object of this invention to provide a clip-on power take-ofi adapter which converts the reciprocating motion of a razor drive motor to a combined oscillatory and linearly reciprocating motion for further utilization thereof.
Another object of this invention is to provide a tooth brush adapter for electric razors which is exchangeable with the razor head in a simple manner and drives an ordinary toothbrush in an effective scrubbing action.
Other objects and advantages of this invention will become more readily apparent and understood from the accompanying specification and single sheet of drawings in which:
FIG. 1 is a perspective view of a novel brush adapter of this invention shown attached to the drive motor of an electric razor and incorporating features of this invention;
FIG. 2 is a vertical elevation, partly in section, of the brush adapter of FIG. 1; and
FIG. 3 is a cross section of the adapter taken on line 3-3 of FIG. 2.
Referring now to the details of the invention, there is shown depicted in FIG. 1 a preferred form of the novel tooth brush adapter 10. This adapter is illustrated clipped onto an electric razor motor unit 12 in place of the customary removable razor head and arranged to drive a toothbrush 14 of the handle type.
The razor head of a typical electric razor, for example a commercially available article manufactured and sold by the Remington Rand Company under the designation Rollamatic, employs a reciprocating head 16 wherein there is generated a reciprocating motion that moves upwardly extending drive fingers 34.
As best shown in FIGS. 2 and 3, the brush adapter 10 is provided With a base plate 24 formed with apertures 25 so located as to freely pass the drive fingers 34 to the interior of a journal box 22 when installed on the reciprocating head 16.
A cylindrical shaft 2% extends from the journal box 22 in a direction transverse to the direction of reciprocation of the drive fingers 34 and it is provided at its outward end with a chuck 32 which removably holds the handle of the toothbrush 14.
The shaft 28 is threaded into the journal box 22 by means of a thread 29, preferably multiple and of large pitch. Thus, a small arc of revolution advances or retracts the shaft 28 longitudinally.
This small rotation, indicated by curved arrows, is accomplished by a bifurcated lever strip 39 secured lengthwise to the shaft 28 and which embraces the previously mentioned drive fingers 34 of the reciprocating head 16 as best shown in FIG. 3.
Consequently, as shown by the double headed curved and straight arrows in FIG. 1, the toothbrush 14 is rocked from side to side and also given a simultaneous push-pull ire scrubbing action whenever the razor motor unit 12 is turned on.
Bar tabs 20 similar to those on the original razor head, engage with the usual spring clips 18 of the razor motor unit and provide quick interchangeability of the adapter it) with the original razor head. A gasket 26 on the shafit 28 where it emerges from the journal box 22 serves to dampen mechanical chatter and vibration of moving parts.
Obviously many modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to be understood that within the scope of the appended claims the invention may be practiced otherwise than as specifically described.
What is claimed is:
l. A clip-on power take-off adapter for converting reciprocating motion .of upwardly extending drive fingers in a razor head of an electric razor into a combined oscillatory and linearly reciprocating motion of a brush comprising a journal box having a base plate positionable and clippable on top of said razor head and formed with apertures in said base for passing said upwardly extending drive fingers from said razor head into said journal box, means including a shaft extending from said journal box in :a direction transverse to the direction of reciprocation of said upwardly extending drive fingers, said shaft having threads of large pitch and being threade'dly received at one end into said journal box so that said shaft is advanced or retracted longitudinally when rotated through a small arc of revolution, means secured lengthwise to said shaft at said one end thereof for embracing and engaging said upwardly extending drive fingers of said razor head, whereby reciprocating motion of said upwardly extending drive fingers is converted into a combined oscillatory and linearly reciprocating motion of said shaft, and means to position said brush at the other end of said shaft.
2. A clip-on power take-off adapter for converting reciprocating motion of upwardly extending drive fingers in a razor head of an electric razor into a combined oscillatory and linearly reciprocating motion for further utilization thereof, comprising, a journal box having a base plate positionable and clippable on top of said razor head and formed with apertures therein for passing said upwardly extending drive fingers from said razor head into said journal box, means including a shaft extending from said journal box in a direction transverse to the direction of reciprocation of said upwardly extending drive fingers, said shaft having threads of large pitch and being threadedly received at one end into said journal box so that said shaft is advanced or retracted longitudinally rwhen rotated through a small are of revolution, and means secured lengthwise to said shaft at said one end thereof for embracing and engaging said upwardly extending drive fingers of said razor head, whereby reciproc-ating motion of said upwardly extending drive fingers is converted into a combined oscillatory and linearly reciprocating motion of said shaft.
3. A clip-on power take-0E adapter for converting reciprocating motion of upwardly extending drive fingers in a razor head of an electric razor into a combined oscillatory and linearly reciprocating motion for further utilization thereof, comprising a journal box having a base plate positionable and clippable on top of said razor head and tormed with apertures in said base for passing said upwardly extending drive fingers from said razor head into said journal box, means including a shaft extending from said journal box in a direction transverse to the direction of reciprocation of said upwardly extending drive fingers, said shaft having threads of large pitch and being threadedly received atone end into said journal box so that said shaft is advanced or retracted longitudinally when rotated through a small are of revolution, 2. bifurcated lever means secured lengthwise to said shaft at said one end thereof for embracing and engaging said upwardly ex-tending drive fingers of said razor head; and brush means secured to the other end of said shaft, whereby reoiprocating motion of said upwardly extending drive fingers is converted into a combined oscillatory and linearly reciprocating motion of said shaft and brush means.
