Abstract

A hand carried member contains an electric motor, a driven shaft and means connecting the shaft to the motor whereby the rotary motion of the motor imparts a reciprocating motion to the shaft. First brushing device including a reciprocatable brush can be detachably secured to the shaft whereby the brush will be subjected to the reciprocating motion. Second brushing device including a brush which can be rotated but which cannot display reciprocating motion and means for converting a reciprocating shaft motion to a rotary motion for rotating the rotary brush can be detachably secured to the shaft whereby the brush will be rotated.

UUUUJUUUU v2 ELECTRIC SILVERWARE BRUSH FIELD OF THE INVENTION SUMMARY To provide both types of brushing action, I employ an elongated hollow member containing an electric motor, means to convert themotor rotary motion into a reciprocating motion and a shaft reciprocated by the means.

A first brush device including a first brush which cannot rotate but which can be reciprocated can be detachably secured to the shaft whereby the first brush exhibits the desired back and forth motion.

"A second brush device including a second brush which can be rotated but cannot exhibit reciprocating motion and means for converting the reciprocating motion of the shaft into rotary motion of the second brush can be detachably secured to the shaft in place of the first brush whereby the second brush exhibits the I desired rotary motion.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective of my invention ready for use;

FIG. 2 is a section illustrating my invention ready for use as a reciprocating brush; and

FIG. 3 is a section of my invention ready for use as a rotary brush.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Referring now to FIGS. 1-3, an elongated hollow casing 10 has an electric motor 12 disposed in one end with an end opening 14 through which the power cord 16 of the motor extends. The motor has an axis extending transversely to the axis of the casing. The motor shaft rotates a disc 18. A linkage 20 pivotally secured at one end to an offset connection point 22 on the disc is secured pivotally at its other end to a transverse pin 24 in one end of shaft 26. The casing 10 has an axial channel 28 in which shaft 16 is disposed. The linkage connection causes the shaft 16 to reciprocate.

An opposite end of casing 10 has a recess 30 exposing the free end of the shaft. A brush 32 having an axial opening 34 with means 36 for detachably engaging the free end of the shaft can be used whereby the brush is reciprocated.

Alternatively a rotary brush 38 can have an axial bore 40 with a pin 42 extending transversely into the bore. A shaft extension 44 detachably securable at one end to the free end of shaft 16 is reciprocable back and forth in the bore. Extension 44 has helical grooves 46 on its outer surface which engage the pin. The brush has means 48 detachably engaging the wall of the recess whereby the brush 38 cannot exhibit reciprocating motion. As a result, the back and forth motion of the shaft extension causes brush 38 to rotate.

While I have described my invention with particular reference to the drawings, such is not to be considered as limiting its actual scope.

Having thus described this invention, what is claimed as new is:

1. In combination:

an elongated hollow member having an opening at one end;

electrically operated means in the member including a shaft having one end at said opening and a mechanism to impart a back and forth reciprocating motion to the shaft;

first brush means adapted for detachable connection with said one end of the shaft and including a first brush to which is imparted said reciprocating motion; and

second brush means adapted for detachable connection with said one end of the shaft and said one end of the member, the second means including a second brush which can be rotated and a mechanism to convert said reciprocating motion of the shaft to a rotary motion which causes said second brush to rotate.

2. The combination of claim 1 wherein said electrically operated means includes an electric motor having a rotary motion, said mechanism converting the rotary motion of the motor to said reciprocating motion.

3. The combination of claim 2 wherein the shaft extends in the longitudinal direction of the member and the motor has an axis extending at right angles to the axis of the shaft.

4. The combination of claim 2 wherein said mechanism includes a disc rotated by said motor and a linkage which is pivotally secure at one end to the shaft and at the other end to an off center point on said disc.

Claims

1. In combination: an elongated hollow member having an opening at one end; electrically operated means in the member including a shaft having one end at said opening and a mechanism to impart a back and forth reciprocating motion to the shaft; first brush means adapted for detachable connection with said one end of the shaft and including a first brush to which is imparted said reciprocating motion; and second brush means adapted for detachable connection with said one end of the shaft and said one end of the member, the second means including a second brush which can be rotated and a mechanism to convert said reciprocating motion of the shaft to a rotary motion which causes said second brush to rotate.
