Application filed October 24, 1917. Serial No. 199,373.

States, residing 'at Los Angeles, in the county of Los Angeles and State 'of California, have invented new and useful Improvements in Mechanism for Manipulating the Spinal Muscles of the Human Body, of which the following is a specification.

While our invention in a modified form may be employed for massaging or manipulating other muscles of the human body, the structure hereinafter set forth and described has particular reference to the machine ca pable of being attached to an ordinary form of surgical table so that the spinal zone of the human body, when the body is reclined on the table, may rest over the machine.

An object of this invention is to provide a machine of the character above referred to having a plurality of applicators arranged in series for simultaneously manipulatmg successive portions of the s inal muscles, the action of the applicators eing to pull the muscles away from the spinal vertebrae as in usual osteopathic treatment.

A further object is to provide constantly operated actuating means for the applicators for intermittently and alternately actuating opposite sets of the applicators, so that the muscles on one side of the spinal column may be first manipulated and then the other side with equal pressure and efi'ect.

A further object is to provide means for supporting the applicators in such positions that a combined lateral and rocking motion may be imparted thereto during the operation of the machine, such motion being best adapted to induce the results sought to be obtained. ther objects will appear as the description progresses.

Having in mind the above and other objects, we have shown in the accompanying drawings, forming a part of this specification, a preferred embodiment of our ideas, which we will now describe in detail.

Figure 1 is a side elevation of a surgical table of ordinary form, partially in action, showing our machine attached thereto in operative position.

2 is an end elevation of the same, partly in action.

Fig. 3 is a plan view of one end of the table with the assembled machine mounted thereon.

F1g. 4 is an enlarged' transverse section of our machn 1e as shown in Fig. 3, in which a typical pa r of applicators 1s shown.

Fig. 5 1s a longitudinal section of the same, the applicators being shown partly in actlon.

In the drawings, the same reference characters are employed throughout the several views for indicating the same or like parts.

Although we have shown in the drawings a preferred embodiment of our invention, we do not desire to limit the same to the form of device shown, for we conceive it to be possible to substantially alter the structure w1thout enlarging the scope or departin from the spirit of our invention.

he table 10 on which our machine is mounted is of the usual form except that an opening 11 is formed centrally therein between the edges and near the head of the table, through which opening the application of our device to the human body may.

be made, as hereinafter set forth. As shown the table 10 comprises a fiat board top 12 with a suitable cushion 13 suitably attached thereto for covering the top.

The mechanism of our machine is supported at opposite ends of the opening 11 by means of a pair of similar frame members 14 and 15 which are held on the bottom of theboard top by means of screws or bolts 16. A driven shaft or spindle 17 is revolubly supported on the frame members in bearings 18 and 19 and is disposed longitudinally of the table, centrally relative to the opening 11 in the table and substantially below the bottom thereof, as shown in Fig. 4. A pair of rock shafts 20 and 21 are pivotally held in the end frame members in bearings 22 and 23, respectively, and these shafts parallel the central shaft 17 and cocupy planes substantially above and on opposite sides of that of the shaft 17 A motor 24 may be suitably mounted on a base 25 attached to the bottom of the table, or otherwise, and we prefer to operate the shaft 17 by means of a worm gear set com prising a worm 26 held on the motor shaft and a worm gear 27 secured to the driven shaft 17, the gear and motor bein preferably positioned midway of the on s of the shaft 17. The ratio of the gear 27 to the worm 26 should be such that the speed of the shaft 17 may be reduced suficiently to provide against discomfort to the one being movement ei cieseriieecia epniieeeoi's A are rigioiy neid necking sopnorts "I on which have the '"eeii cronies and s ze edenieci to es iooseiy ioefl. on the shame 29 and 21 mi r so es lo move l'reeiy thereon. esters erreng'eci 'n two sets iongiendineiiy on fine men and in pains ie'bemiiy enie and are composed oi meiei bends 28 "e ni around in ine some a loop, over soiz sponge rubber 2 sigh resilien-oy is goiseeci, and reisiiveiy enin ieeihei or s'iseips' 3i) ere provided covering the nivioei" the oi the rubber ei enbs end strips being firmly held on b? means oi screws or rivets 31 inieeoeo 1 ,7 i sncl-exienulng "ongn Eel, ii-
