As shown on the drawing:
The casing in serves both to house the operative parts and to constitute a handle for the device. This casing is preferably made of a molded plastic material of suitable nature conbushin 1,124, the atte eb i stituting at one and the same timeta-casing-havins .seod .eiectricaleinsnlatins, properti s :eood wearing-characteristics anxi ercvidin .aneattm tive outside annea ianc fe the a c e.

A rubber washer 26 having a diametei gsi tl' fily -lar r.thanitheiiiametenefztherh a fl en a thessid :wall eefcther eee vent rattlin cerzehattennsre direction. Reciprocable in a suitable recess in this stud but fixed in the top end of the plunger, is a brass guide pin 28, serving to guide the reciprocation of the plunger.
The head 25, either shaped as shown or having some other suitable configuration, is itself employed as a massaging tool, while various other tools or devices well known in the art may be attached readily to the head. For example, in Figure 6, I have shown a suction cup 29 having a threaded shank 39 which may be threaded into the internally threaded recess 3| of the bushing 24. Whenever the head 25, which is preferably shaped to conform to the contour of the casing, is being employed as the massaging tool itself, a plastic screw 32 may be inserted in the end of the head in order to complete the rounded surface thereof. However, by withdrawing this screw, any other massaging ,tool such as a suction cup or flexible fingers or any other such tool may be readily attached.
The cord for supplying current to the solenoid coil as indicated at 33 is readily brought out to the outside of the casing through an opening 34 located where it will not interfere with the hand grip on the device.
For adjusting the air gap and the length of the stroke of the plunger, the stud 21 is provided with kerf 35. A look nut 21' will retain the adjustment of the stud. Ordinarily, the air gap and the compression of the spring 2| will be adjusted before assembly of the solenoid into the casing. A distorting squeeze applied to nut 22 will sufice to lock it when adjusted.
To improve the hand grip, a grooved area such as 36 may be molded on the surface of the casing.
It will now be apparent that this invention provides a massage vibrator of extreme simplicity of construction. No separate handle is required. A molded plastic one-piece casing serves as a handle, electrically insulates the device, and encloses all moving parts. The casing has only one major opening, that is, the open end of the recess defined therein, and this opening is utilized for final assembly and as the aperture in which the vibrator massage head moves. The casing is thin for lightness at the opposite end where no strain is imposed, and is thickened at the sides of the recess where the solenoid is supported on screws extending through the casing wall. Preferably a plug 3'! of sealing wax or some suitable plastic material having electrical insulating properties will be used to cover the recessed ends of these screws.
The spring loaded plunger, having a straight line movement, moves freely into and out of the solenoid coil to impart the vibrations to the massaging device or tool. The readily adjusted air gap regulates the intensity of the magnetic inward pull of the coil, while an adjustable compression spring determines the force of the outward thrust of the massaging tool. By varying and correlating these two adjustments, various degrees or intensities of vibrating force may be obtained.
Although I have shown and described one particular embodiment of my invention, I do not desire to be limited to the exact details of con- 4 struction herein shown and described. It should be understood that the invention comprehends all variations and modifications within the scope of the appended claims.
I claim as my invention:
1. An electric vibrator comprising a hollow casing having a rounded exterior contour suitable for gripping with the palm and fingers of the user, said casing being open at one end, a solenoid coil insertable through said open end and secured within said casing, a plunger extending axially of said casing and coil toward the open end of said casing, a resilient seal member mounted on said plunger and movable therewith and engageable with the interior walls of said casing to seal said open end of the casing, said resilient seal member having an exterior surface protruding out of said casing to constitute a massaging tool, and means carried by said seal member for attachment thereto of other massaging devices.
2. An electric vibrator comprising a one-piece molded plastic casing having a centrally extending recess, said casing being open at one end thereof and the exterior surface of said casing being shaped to constitute a hand grip for the vibrator during use, a solenoid coil insertable into said casing through said open end, means electrically insulated from the outer surface of the casing for mounting said solenoid coil within said recess, a plunger reciprocable axially of the coil and extending toward said open end of the casing, means substantially closing the open end of said recess and operatively connected with the plunger to vibrate therewith, said casing and said closing means being composed of insulating material serving to completely enclose and electrically insulate the current carrying portions and all metallic portions of the solenoid mechanism, said closing means having an exterior surface protruding out of said casing to constitute a massaging tool, and means carried by said closing means for attachment thereto of other massaging devices.
