ELECTRIGALLY-OPERATED MASSAGING DEVICE.

Specification of Letters Patent.

Patented Nov. l 2, 1912.

Application filed May 13, 1912. Serial No. 696,862.

To all whom it may concern: I

Be it known that I, WILLIs I. MILLER, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Electrically- Operated Massaging Devices, of which the following is a specification.

ing the same with the motor frame.

This invention 'appertains to electrically operated massaging devices, and is an improvement on the machine patented to me October 22, 1907, No. 868,795.

In the accompanying drawings, Figure 1' is a plain elevation of the machine complete, and Fig. 2 isa' sectional elevation thereof vertically through-the axis as viewed in Fig. 1. Fig. 3is an enlarged sectional elevation of a portion of theshell and the nipple which receives the stem of the applicator. Fig. 4 is an elevation of a portion of the handle stem and the spring connect- Fig.

' 5 is a plan View looking down on Fig. '1

with the upper half of the shell sectioned horizontally just above the nipple for attaching the applicator.

Several materialimprovements appear in this case over the above patent as will be seen in the course .of this description, and the present mechanism comprises a two-part shell, or shell-in semi-spherical sections, or

halves as indicated'by' 2-and 3 respectively and overlapped at their edges in'a plane at right angles to the axis of the motor shaft 8 and the inner section fastened by screws to the motor frame 4 while the outer section is rotarily supported as hereinafter described. The coils m for the motor are arranged Within this frame and an eccentrically mounted eight 5 is fixed on the extremity of the motor shaft outside of said frame as seen in Figs. 2 and '5.

The handle it by Which the device is held in use has a tubular stem 6 through which the conducting wires are passed, and, the

- said stem is connected withthe said frame 4 by means of a spring 7, Figs. 2 and 4.

The said spring is of segmental or bowed pattern as, seen in Fig. 2, and -is rigidly attached to the extremlty of stem 6 at one endand pivotally connected with the'frame 4'at the other, the pivot means comprising a stud 8 on frame 4 over the inner bearing for the motor and projecting through a loop 9 thrown up from the outer portion .of the spring 7, while alip struck from said fingers 10 are at right angles to each other and one may be'defined as vertical and the other as horizontal, the latter resulting particularly from the spring fingers 10. With the speed of the motor and the throw of the weight 5 the whole eifect is substantially equivalent to a universal joint movement. This is evidenced because in addition to the vertical and horizontal movements above referred to there is'also a more or less direct axial movement in the motor shaft, or a sort of pounding effect in that direction as ex pressed in short successive strokes.

A feature of construction in this device is the location of the weight 5 on the end of motor shaft s while the spring 7 is applied at the opposite end of said shaft, and since the shaft and the motor frame have the I spring 7 as their sole support and the said spring comes at one end of shaft 8 and the eccentric Weight 5 at the other the vibratory effects must necessarily be pronounced. The outer shell section 2 is rotatably secured upon the frame 4 by pivot screw 16 at its center and is rotatable in respect to the inner section 3 on said pivot according to the position it is desired to give to the applicator a as, for example, the full lines or.

the dotted lines thereof Fig. 5,or any intermediate position, and the outer section is locked in place by the tongue 18 struck from the rim of said section and adapted to be pressed against the rim beneath or within by hand controlled screw 20 and thus frictionally lock'the said outer section in place. The screw 20 obtains bearing by passing through the comparatively deep base of the nipple 12, and the applicator has a threaded stem adapted to be removably screwed into saidnipple. Of course various forms of applicators may be interchangeably used according to the service desired.

What I claim is:

1. In a massaging apparatus, a main frame and a motor therein, a shell having semi-spherical parts overlapped at thenedges, the inner part fixed on said frame and the outer part having a pivot on the said frame and rotatable in respect to the inner part to any desired position, an applicator support on said outer part and means to frictionally lock the said part in adjusted position.

2. A massaging apparatus having an internal frame and an electric motor mounted therein, a handle and a spring su porting the frame on said handle, in com ination with a two-part shell having one part fixed rigidly to said frame and the other part rotatably supported over the edge of said fixed part, means to lock said shell parts together at their meeting edges, an applicatoron said rotatable part, and the said fixed part having an opening relatively larger than said handle through which the handle engages with said spring.

3. In a massaging machine, a main frame and a motor therein, a handle and a segmentally curved spring support therefor connecting .the said handle with said frame opposite the axis of said motor, the saidspring provided with. bowed lateral spring portions bearing against said frame and the said handle located at right angles to the axis ofsaid motor.

. 4. In a massaging machine, a mainframe and a motor therein, a handle and a curved spring supporting said handle having pivot E. M. Fismm, F. C. MUSSUN.
