tion is to provide a portable massage 'implement the efficiency and convenience in use of which will be materially increased by storing within the apparatus itself a generating source of current su ply.

Other objects wili) appear hereinafter.

rI`he invention stated in general terms comprises the improvements 'to be presently described and finally claimed.

The nature, characteristic features and scope of the invention will be moreffully un derstood from the following description taken in connection with the accompanying drawings forming part hereof, and in ,which Figure 1, is a central sectional view of .a

Ymassage implement embodying the invention. Fig-2, is a sectional view taken on the line 2 2 of Fig. 1. Fig. 3, is a view partly in elevation and partly in section of a slightly modified form of the invention, and Fig. 4, is an elevational view of a still further modified form.

In the drawings there is shown a tubular metallic handle a., by means of which the instrument is manipulated. This hollow handie is screw threaded at each end for the reception of similarly threaded caps b and b1. Carried by the up er cap, is an electric motor c, consisting ofp the usual field and armature and complemental commutator and brushes. The armature and commutator are mounted upon the shaft d, which carries an eccentric pin d1, at its outer end. To the motor c, is fixed a frame work c1, having piv-` otal relation with which is a vibrator rod e. One end of this rod is slotted and is ada ted for the reception of the eccentric pin .1,in

-order that a lateral vibrating motion may be imparted to a vibrator member f, having screw threaded engagement with the op osite end of the rod e. The above descri ed parts may be incased by a housing g, screwed as at g1, to the motor and which may be two-part if desired. The motor is provided with a contact point l, shown'as being upon the upper cap b. The cap b, is provided with a brass contact point 2. (lontained within the chamber of the handle a, is current generating means which may be one or more dry batteries, 3, of which two are shown in the drawings.l These batteries are zinc covered and are provided with brass contact oints 4, and may be incased by means oi) a tubular insulating medium 10. By this arrangement current may be caused to flow to the motor by reason of the fact that the brass and zinc parts contacting with one another form a circuit which may be made and broken at will by means hereinafter set forth'.

Between the cap b, and the top of the uppermost battery is shown a spiral spring This spring is useful in serving to pre- -vent contactbetween the batteries and motor when the device is accidentally overturned or when lying upon its side, by the batteries sliding up againstthe contact point 1. These batteries are removably fits ted within the handle and may be readily removed and new onesreplaced throu h the *instrumentality of the removable cap By the above described arrangement mas-- sage devices may carry their own source of current supply, which obviously is advantageous, especially for traveling pur oses and where electrical current is not avai able.

In order to use the above described massage implement t is merely necessary to give the handle a, or cap b, a twist of the wrist which will cause the contact points to contact one with the other to form a circuit and current will flow to and cause to operate the motor, whereupon a vibratory motion will be imparted to the vibratory member f. Likewise a twist of the wrist will break the electrical connections and stop the motor.

`In Fig. 8, a spring controlled push button 6, is shown as providing means for making and breaking the circuit connections between the batteries and motor. Fig. 4, illustrates the use of a pair of handles a, in order that additional batteries may be carried by the massage implement. In this event they may be coupledtogether as at 7, and may be provided with a pair of connected push buttons 8, for making and breakin the circuit.

am aware that electrically operated massage implements have been used before,

but in such cases the current has been supplied rom an outside source of'sipgly 1n contra-distinction from being carrie y the apparatus itself, hence I do not claim such as my invention. However, I do not wish bythe use of the above language to limit my invention further thanthe prior state of the art may require, but

Havln thus described the nature and objects o my invention, What I claim as new and desire to secure by Letters Patent is A device of the character described,4 comprising a tubular casing capable of rotating said casing having screw-threaded ends, top

and bottom caps accommodated by said screw threaded ends, a motor equipped with Y a massage device carried by the top cap, a

battery ca able of endwise movement through sai casing the cells of which are arranged end to end, one pole of the battery formed by said cells being normally out of contact with a permanent terminal of the motor and -the other pole of said battery being in direct contact with the bottom ca whereby when the said casing is slighty rotated the battery is moved endwise for electrically contacting with the motor terminal for closing the circuit and resilient means interposed between and insulated from the motor terminal and battery for maintaining an open circuit, substantially as described.

In testimony' whereof I have hereunto signed `my name.
