The portion of '.the.ar 1ature T9 whichpene- Hates into thehousing if O is surrounded by. Sole- 3 noid coil 33 which extends substantially for the whole length of the housing. Internally of the coil 30 and surrounding the armature I9 is a sleeve 3!, herein disclosed as a thin cylindrical member, preferably of brass or other like metal, which is rigidly connected to disc 29, as by forcefitting or brazing or in any other suitable manner, and which is cut lengthwise to provide a slot 32. The end of sleeve 3| opposite to that which is connected to disc 29 passes through spacing washers 33 and 34, insulating disc 35, and washer 36, and is flared outwardly to help retain the said washers and disc. A core 31 is provided in the center of the lower part of the housing l within the sleeve 3|, and is retained within said sleeve in predetermined longitudinal positioned rela- 4 her rigid with said armature and extending outwardly of said casing through an opening thereof, a flange rigid with said armature, two springs engaging said flange on opposite faces thereof and resiliently reacting to the vibrations of said armature, a number of patter rollers, and a support rigid with said outwardly extending member for said rollers, each of said rollers being so mounted in said support as to be freely rotatable with respect thereto about an axis perpendicular to the direction of the vibrations of said armature.

2. A mechanical beauty aid, comprising a casing embodying an open cylindrical member, a

tionship by the engagement of a pin 38 with slots The device operates as follows. The sinusoidal impulses of the alternating current fed through the wires M and the wires 45 to the coil 30 produce a pulsating magnetic field within the space enclosed by the coil 30. Said field induces pulsating magnetism in the core 31 which sets the armature IS) in vibrating motion. This motion is amplified by the action of opposing springs 21 and 28, which are designed to match the frequency of the feed current, whereby to achieve a smooth and effective vibration of the armature with a limited size of solenoid, and which also prevent any sharp blows from occurring between the armature and the stationary parts of the vibrator. The engagement of square guid member 21 with the corresponding opening of cap 26 prevents the armature I9 from rotating about its axis, and thereby from transmitting to said roller support l3 any motion other than the desired vibration. This maintains the axis of the patter rollers in invariable orientation with respect to the handle Ill. The patter rollers I4 with their support l3 vibrate with the armature, and thus impart to the skin a succession of light pats achieving the massage effect desired. As the vibrator is manually driven about the area to be massaged, the patter rollers rotate freely with respect to their support 13, thereby eliminating any harmful or undesirable rubbing effect on the skin, and rendering the device suitable for massaging even the most delicate portions of the body.
