To all whom t may concern:

Be it -known that I, DANIEL TIBBALS, a

citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Electric Massa e-Rolls, of which the following is a specification, reference being had to the accompanyingl drawings,l

forming a part hereof, in which- Figure 1 is a longitudinal sectional view, partly in elevation, of my new-electric massage roll or instrument; Fig. 2'is a fragmentary elevational view thereof, partly broken away; 3 is a sectional view taken approximately on the lines 3-3 of Figs. 1 and 2; Fig. 4 is a plan view of the under side or face of the closure for the up er en d of the shell or casing forming the andle of mv new instrument and which closurealsodirectly supports the massage roll; Fig. 5 1s a vertical sectional view through said closure taken approximately onV the line.5-5, 4; Fig. 6 is an elevational view of the 1nduction coils and their supporting-frame used in my new instrument, showing also the armature therefor and the several leads from the secondar winding thereof, whereby the intensity o the induced current supplied to the electrodes may be regulated or varied; Fig. 7 is a detail sectional view taken approximately on the line77 of Fig. 6; and Fig. 8 is a diagrammatic view of the primary and secondary electric circuits through my new massage instrument or roll.

This invention relates to certain new and useful improvements in electric 'massagelinv the like 5 preferably electrically secured to struments or rolls, ,the objects of my invention being to provide an instrument of the kind stated which is comparatively simple in construction, which may be manufactured and supplied or furnished users or consumers at small cost, in which the intensity` of the current or electric sensation applied to the user may be readily and easily reguinstrument is adapted to distribute the mastion, arrangement, and combination of parts,

all as hereinafter fully described and afterward pointed out in the claims. Referring by numerals to the accompanying drawings, 1 indicates a preferably openended metallic or electrical conducting cylindrical shell or casing, which is adapted to .provide the handle of my new massage instrument and which also forms art of the primary circuit therethrough, as ereinafter more fully appearing.

Within the lower portion of shell 1, as shown particularly in Fig. 1, is removably positioned a suit-able electric battery or cell 2 preferably cylindrical in shape and of such size relatively to the interior diameter of shell l so as to fit snugly therein, battery 2 being preferably of that type' wherein the outer Wall thereof, as at 2, forms one element of the batteryl and the head of vthe other element, as at 2b, projects upwardly slightly beyond the top thereof. Battery 2 is preferably insulated at its sidesfrom the sides 'of shell 1 bymeans of suitable insula- -tion .material 3 'interposed therebetween and is removably heldin position in shell 1 by means of a suitable metallic cap-piece 4 threaded on, and adapted 'to close` thev lower end of shell 1, a suitable coiled spring or cap 4 and interposed therebetween and the lower end of battery 2 bei adapted notv only to normally contact. and thereby form an electrical connection between battery element vor contact 2'L and cap 4 and shell 1', 'but alSo to normally maintain battery element or :Contact 2b 1n constant contact with a suitable metallic plate or contact 6a 'arranged'on the under face of, and secured in position by means ofa suitable metallic screw 6 extendingupwardly through the base 7 of' a 4member A removably arranged in casing land bodily rotarily movable. about the longitudinal axis thereof abovebattery 2.asshown particularly in Fig. l. This memberA comprises said base 7, which-.is preferably a disk of any suitable insulation material, a head 8, which is likewise preferably a disk of any suitable insulation material, and a vertically-disposed substantially U-shaped metallic' frame 9 interposed between said base 7 and head 8, said frame 9 being integrally provided with upper and lower flanged portions 9a and 9b, respectively, adapted to receive and electrically engage or contact with, respectively, said screw or contact 6 and a screw or other suitable contact 10 extending upwardly through said head 8 and whereby also said frame 9 is securely held in position between said base 7 and head 8. Mounted on and carried by' said frame 9, as shown particularly in Figs. 1 and 6, are induction coils 11-11. These coils 11--11 are preferably supported on frame 9 by means of suitable metallic screws 12--12 passed through one flange, as, for instance, iiange a, of frame 9 into the cores thereof, as shown particularly in. Fig. 6, the said cores, screws 12-12, and the portion of ange a of frame 9 between said screws thereby forming substantially a horseshoe-shaped core or magnet adapted to be magnetized and 4having its opposite leg-portions closely adjacent, for purposes hereinafter appearing.

Arranged preferably on the core of lower coil 11, and insulated therefrom and from flange a of frame 9 and coil 11 by suitable insulation blocks 13 and 14, as shown particularly in Fig. 6, is the leg 15 of a small substantially U-shaped metallic bracket 15 having its body-portion lying between and spaced from coll 11 and the body-portion of frame9 and its said leg 15 and opposite leg 15 presented forwardly as shown, see particularly Figs. 1 and 6..

rl `he primary winding of coils 11 and 11', which may be of any suitable length, is preferably in series, one end, as at c, thereof being grounded upon, or electrically connected to, said insulated le 15 of bracket 15, as shown particularly in Fig. 7, and the opposite end, as at d, passing through a suitableopening in said flange a of frame 9 and being electrically connected to a suitable extended arc-shaped contact terminal 16 arranged on the outer face of head-disk 8, see particularly Figs. 1 and 3. Secured, as shown, and electrically connected to the opposite flange, or to flange b, of frame 9, is an elongated spring-member 18 angularly bent, as shown, to normally loosely lie against and swingably contact at its lower or free end with said leg 15 of bracket 15; and arranged on the inner face of, and carried by, the free end of springmember 18, as shown, is an armature member 19 adapted to coperate with and be alternately attracted by and drawn out of engagement with the legs of said magnet, as` will be well understood. The secondary winding of said coils'is provided with, or divided by, a plurality of leads electrically incenso connected, respectively, to suitable spaced apart or separated contact terminals j, z', h, g, f, and e, arranged preferably in the form of an arc on the outer face of head-disk 8 and directly opposite said contact terminal 16, as shown particularly in Figs. 3/ and 6, so that the intensity of the induced current supplied to lthe electrodes of the instrument may lbe varied or regulated, as hereinafter more fully appearing, said winding with its said leads being formed or wound as follows: The wire of the secondary winding, which is, as is usual, very fine, is at one end first suitably connected preferably to the end al of the primary winding, then given a predetermined number of windings or turns on' the primary winding, then led to,

and electrically connected with, rst contact j, then again given a predetermined number of windings or turns on the primary winding, then led to, and electrically connectedwith, second contact z', then again given a predetermined'number of windings or turns on the primary winding, then led to, and electrically connected with, contact h, and so on throughout said series of separated contacts, there being preferably approximately on the coils here shown forty-five feet of wire of the secondary winding wound on the primary winding between the several respective contacts of said series and the secondary wire being finally electrically connected at its other end to the last contact e. Secured, by means of suitable screws or other fastening devices 20, in, and adapted to close, the upper end of shell 1, is a prefer-l ably rounded, somewhat coneshaped block of suitable insulation material 21 preferably provided on its under face with an integral depending ring-shaped portion 22.

23 indicates a suitable metallic roller which is adapted to provide one of the electrodes of my new instrument. This roller 23, whichy is preferably hollow and garovided on its periphery with a plurality o circular or cup-shaped recesses for depressions 24;, is suitably supported by, and journaled in and between the outer ends of, the outwardly-extending legs 25-25 of a substantially U-shapedmetallic frame 26 mounted on said insulation block 21 and held in position thereon by, and electrically contacting with, a suitable metallic through-bolt 27 eX- tending longitudinally vthrough said block 21 with its lower endwithin said ringportion 22 and threaded to receive a securing-nut 28.

Suitably secured at or adjacent one end, as by screws 29, on, and preferably adjacent the outer edge of, the under faoe of' insulation member or closure 21, are suitable substantially arc-shaped cont- act members 30 and 31 adapted, respectively, to coperate v and electrically engage on the rot-ary movement of member A with said contact 16- and said series of separated contacts j, i, Iz.,

Aso

and e. arranged on disk or head 8, sal contact members and 31 being each at its free end gradually bent or curved downwardly and then at its end bent upwardly, sol as to provide curved portions, as at 30 and 31', respectively, adapted to ride easily and smoothly over and electrically engage with said contacts on disk or .head 8. Suitably secured on the under face of said insulation block 21 is a short metallic strip 32 adapted to electrically connect said contact member 31 with said through-bolt 27 and its carried roller or electrode 23; and also arranged on the under face of block 2l and electrically connected to contactmember 30 is a short metallic strip 33 eX- Atending outwardly to the edge of block 21,

where it is bent upwardly, as at 33, and thereby adapted to electrically contact with, and complete the primary circuit to, shell 1;

At proper place relatively to head-disk 8, shell 1 is provided with a circumferential slot, as at 34, and arranged on shell 1, so as to cover said slot 31, is a ring 35 held in position by means of a preferably knobheaded screw 36 threaded into said disk 8 and which screw 36 serves also as operating means for rotarily moving said member A in shell 1 to move said contact members 30 and 31 into electrical engagement with 4the said contacts onhead 8 and thereby complete the primary circuit and throw the electrode or roller 21 into the secondary circuit.

When operating-screw 36 is at the letthand end of slot 34 or at zero or normal position, contact- members 16 and 30, as well as also said contact-member 31 and said series of separated contacts, are out of contact or electrical engagement and the primary circuit .is open. On member A being rotarily moved to the right, contact-members 16 and 30are brought into engagement and the primary circuit is then closed and com leted'from Ibattery element or contact 2b, t rough plate v6 :screw 6, frame 9 and its flange I), springl member. 18, bracket 15, primary-winding of coils 11 and 11, contact-member 16, strip 33, casing or shell l, cap 4, and coiled sprin 5 to other battery element or contact 2'. ormally, as before stated, the free end ofspring 18 is in electrical engagement with bracket 15; as soon, however, as thecurrent from battery 2 begins to circulate in said primary winding of coils 11 and 11 and around the cores thereof, said cores forming said magnet become magnet-ized and thereby said armature 19 is alternately attracted and, on the intermittent breaking of the current by said spring 18 being so moved out of contact with bracket 15, drawn out of electrical engagement therewith by spring 18 returning to normal position. These said act-ions ta e place in rapid succession and constantly produce a change in the lines' of force passing through sald magnet or cores, thereby inducing a'current in the secondary winding, the current from which will flow through one of sai-d separated contacts j, i, lz, g, f, or e, depending upon the rotated position 'of member A, through contactmember 31, strip 32, bolt 27, and frame 26, to electrode or roller 23, the intensity of such induced current -belng readily regulated or varied by bodily rotating member A and thereby bringing contact member'3l into electrical engagement with one of said contacts of said series, as may be desired, the induced vcurrent flowing through contact y' being of least intensity and the induced current flowing through contact e being of greatest intensity. The shell or casing 1 may be provided adjacent slot 34 with a series of numbers, as shown, to indicate the engagement of contact member 31 with a particular contact of said series and thereby enable the operator to visually gage the strength or intensity of the current supplied to the electrode or roller 23. By arranging said coils as shown with their cores closely adjacent, the pulsations of the primary circuit are exceedingly rapid withv the armature 19 moving or swinging back and forth likewise exceedingly rapidly and shocks to the user are consequently eliminated, and by my construction as described I am enabled to develop a comparatively large or heavy induced current in the secondary winding with a small battery and, at the same time, conserve the energy, and thereby lengthen the life, of the battery.

In operation or use, my new instrument may be personally employed, and the massage roller 23 applied to or rolled upon the portion of the bodyl'to be treated, by the patient himself, or the treatment may be applied upon the patient by an operator or the like. In the former case shell 1 is grasped in the hand of the patient and the massage roller or electrode 23 personally applied to or rolled upon the portion of the ody to be treated, the current flowing from electrode or roller 23 through the body of they patientback to shell 1 and battery 2. Inthe latter case, an electrode E comprising a suitable referably wooden or other insulation han le 37 provided at one end with a metallic plate 38 having secured thereto a sponge or'the like 39 and electrically connected, as shown, to cap 4 by means of a wire or the like 40, is grasped 4by handle 37 in the hand ofthe patient or operator, wet sponge 39 applied to a portion-of the body of the patient and roller or electrode 23 then by the operator a plied to or rolled upon the portion of th'e liody of .the patient to be treated, the current, as will be clear, flowing lthrough the body of 'the patient. By means of `said indentations or vns herein shown and described without departing from the nature and ,spirit of .my 1nvention.
