MASSAGE-MACHIN E- Specification of Letters Patent.

Patented Dec. 11, 1906.

Application filed April 26, 1905. i Serial No. 257.420.

To all whom it may concern.-

Be it known that I, CHRISTIAN G. Fansa citizen of the United States, at Philadelphia, in the county of Philadel hia and State of Pennsylvania, have invente certain new and useful 1m rovements in-Massage-Machines, of which t e folresiding lowing is a specification.

My invention relates to a machine for manipulating a part or the whole of the bodyby percussion for the purpose of affecting the nervous and muscular system and the general circulation.

The nature of my invention will be best.

understood by reference to the accompany a e of drawings, in which e 1 illustrates a side elevation, on a reduced scale, of deviceand the means by which the same may, be operated, the means, as shown, consisting of an electric motor having attached to its driving-shaft a flexible shaft leading to another shaft in the machineforming the subj cot-matter of my invention. Fig. 2 is 'anenlarged side elevation of my device with a portion of the cover in section, showing the mechanism employed for converting to .the machine motion. Fig. 3 shows a vertical section of my device, taken on the line 3 3 of Fig. 2; and Fig; 4 is a similar section taken on the line 4 4 of Fig. 2.

Referring to the letters of reference indicated u on the drawings, and more particularly in ig. 1, A represents my-device in its entirety, and A is Its driving-shaft. B is a motor for driving the same, preferably an electric motor, as shown, having a drivingshaft B, and C is a flexible shaft of coiled wire for transmitting power from the shaft B of the motor B to the shaft A of the massagemachine A.

Referring now more particularly to Figs. 2, 3, and 4, A represents the support' -frame of the machine, at the bottom of whic is arranged a handle A, which the device is manually supported. Z is a bearing fastened part of the supporting-frame A and carrying the shaft A. This shaft is provided with a crank D, preferably a disk crank, which has drilled through its face a number of holes (1 d, &c., no two of which are the same distance from the center. E is a lever fulcrumed at a point e to a yoke E, which in turn is fulcrumed at a oint f to a lug F, projecting tltlpward from t e supporting-frame A. e lever E, which gets its motion from the crank D, has u on its-'lon arm a stud E, which has a sp erical en adapted to rest in one of the holes (1 of the crank D. This stud is threaded into the end of the lever E and arded against turning by a jam-nut e he object of lacing a number of holes in the crank-disk and in having them arranged at va g distances from the center of the shaft is to alter the gyratory throw of the lever E, which may be done, as will be readily understood, by changing the stud E from one to the other of the holes until the desired degree of percussion is produced, which is an important factor in machines of this character. The short arm of the lever E is provided with a detachable flesh-brush G, which may be threaded or otherwise fastened to the end of said lever. This brush is preferably formed of molded soft rubber, having upon its face a large number of projections or brought in contact wit the surface of the body While the lever E is moving at a high rate of speed; but it will be understood that brushes or pads of any description may be employed without departing from the nature and sec e of m invention. The working pints of t e mac e are inclosed in a casing which mayin a convenient way be secured to the supporting-frame A.

Having described my invention,

rongs g, which are what I claim, and desire to secure by Letters Patent,

1. The combination of a frame provided with a crank and crank-shaft, a lever supported within the frame having one of its ends fitted to an openin in the crank and the other adapted to a flesi-brush, and a yoke swiveled to the frame and formin a bearing for said lever so as to receive the t .1st when pressure is ap lied to the flesh-brush.

2. The com ination of a frame provided with a crank-shaft and crank, the latter be ing furnished with an eccentric o ening, a lever provided with a spherical en adapted to rest in said oppning and with an oppositelydisposed fieshrush, and a thrust-bearing for said lever consisting of a yoke swiveled to the frame and having bifurcated ends in which the lever is journaled.

In testimony whereof I affix my signature in presence of two witnesses.

CHRISTIAN G. FENSTERMACHER.
