VIBRA-TIN G MACHINE FOR MASSAGING PURPOSES.

Specification of Letters Patent.

Patented Oct. 15, 1907.

Application filed March 14:, 1904. Serial No. 198,065.

To all whom it 1n ay concern:

13e it known that I, JAY VAN TUvL DANIELs, a citizen of the United States, and residing at London, England, have invented cei'tain new and useful Improvements in Vibrating Machines for Massaging Purposes, of which A the following is a speci ication.

The invention relates to that class of massaging machines capable of being driven by any mechanical means in which an unbalanced wheel is rotated at high speed to produce the vibrations.

The invention consists of the features and of the cornbination and arrangements of parts hereinafter described and particularly pointed out in the claims.

The invention is illustrated in the accompanying drawings in which:

Figure 'l is a side view of the device. Figs. 2 and 3 are face and central sectional views oi the double fly wheel, Fig. 3 being taken on line Z-Z of Fig. 2.

In these drawings l is a casing having a handle 2. In the casing l are assembled the operative parts of the device which comprises the gear wheels or pinions 3, 4, 5 and (i, the shaft 7, the bevel pinion 8 of which gears with the pinion 3 and the double fly wheel 9 on the end of the shaft 7. l0 is a crank connected with the axle of the pinion G for rotating the train o gears.

'As shown the double fly wheel 9 consists oi two disks All and l2 having holes 13 and 14 respectively. These disks are mounted upon the shaft 7 and are held in place By slackening this nut the disks can be turned or moved upon each other, and the relative positions of the holes 13 and 14 can be altered and thus the balance or center of gravity of the wheel changed and the intensity of thek vibrations or taps thus be graduated at will.

In operation any suitable part of the casing l may be rested or pressed .upon the part of the body to be massaged. The operator holds the device in one hand by means of the handle 2 and with the other hand he turns the crank l0, which by means ofthe train of gears rotates the shaft 7 and the fly Wheel 9 which being of greater weight on one side than upon the other imparts vibrations to the casing which are transmitted to the body of the patient. Ii desired a Contact plate may be connected to the casing and this plate instead oi the casing itself is placed on the part of the body. As this contact plate is Well known and forms no part of my invention I have not illustrated it.

W hat I claim and desire to secure by Letters Patent is z* l. ln a machine of the class described, a disk mounted upon a revoluble shaft the center of gravity of which is non-incident to the axis of the shaft, a second disk monnted upon the same shaft of like character, means for varying the positions of the center of gravity of the two disks relative to one another and for rigidly securing the two disks to the shaft in any desired position, substantially asshown and described.

In a machine of the class described, a frame, a revoluble shaft mounted in the frame, a disk of solid metal having a large hole on one side between the axis and the periphery to alter the center of gravity thereof, a like disk mounted upon the shaft with the iat face thereof abutting against the face of the tirst disk, and means for securing' the two disks rigidly together and to the shaft in any desired position so as to vary the position of the two holes thereof, substantially as shown and described.

In witness whereof I have hereunto set my hand in presence of two witnesses.
