Beit kndwn that I, Hnn'nnn'r GQ HI'LL,.a citizen of if the United States, iesidingat Chicago, in the county of Cook and State at Illinois, have invented certain new and useful Improvements in Vibrators, of which the following? is a specification.

.This invention relates to certain improvements 'in for-use in massage and similar mechanico-therapeutic treatments for the stimulation of muscularandnervousaction, and the object of the invention is to provide an apparatus, or vibrator, of 'this general character of a simple and inexpensive natu re adapted for electrical actuation and of a lightand compact structure so as to be capable of convenient and effective use and wherein .is provided means of an improved and simplified char acter for regulating the depth or amplitude of the vibratiops producedby the apparatus so as to'accommodate the device for use in the treatment of disease and ctional derangement in various situatibns and s erein such regulation is necessary forattaining the .bestf fresultsr The invention consists in certain novel features of the constriction and combinations-and 'arrang'ements I of the several of thcfirnprove'd vibrator, whereby a certain advantages'are attained and the device is rendered simpler, cheaper and otherwise better so: v f p g i N e ovel fcatnresof'theinvention-will be careh lly -definedinthe.c]aims.

device may be held and guided by the operatorinpse,

a tinsel cord fi being preferably attached to said handle and having embedded in it the electrical conductors for supplying'current to the motor incased in the casing, from a'suitable source of power, as a lamp-socket for example, I The casing maybe of any desired construe tion and the motor within the same may be of any suitable or desired'size and type, dependent on the re- :quiremhnts of eachparticular case. 4 is the armature shaft held to turn suitable bearinthe shell or casing 1, and 6 a balance wheel rigidly held on said shaft and housed within a projecting portion 5 at one end .or side of the shell or casing, the shaftd having a screw-threaded end portion 7 protruding through and beyond theouter surface of the balancewheel, as is clearly shown in Figs. 2, 5 and 6 of the drawings.

- 8 is a, shaft section, having a'threaded bore wherein the screwthreaded end portion 7 of the armature shaft is held. The shaft section 8 is adapted to be turned upon the screw-threaded shaft lend 7, and thus rigidly secure it thereon and inalinement therewith, and said freeeinds and one of their edges, for the passage of a pin l2, wherein'is held one end: of a toggle-link or element 13,whichis thereby connected to turn with the shaft sec tion'8 on the end of the armature 'sha'ft, but is capable of pivotal movement on pin 12 in and but of axial alinement'with the armature shaft and said shaft section, as

, will be-readily understood. That end of the link 13 which is pivoted betweenthe'lugs 11 is beveled, as

tact with the shaft section 8 between its lugs '11, when the link 13 is in alinement with the section 8 and armature shaft, thus permitting pivotal movement thereof in one direction, but preventing it in the other. The outer'end of the link or element 13 is preferably flattened, as at 14, and located between two spaced apart -forks 15 of another toggle-linker element, a pin 16, be-

ing passed through openings in the end 14 and forks 15, to pivotally connect the links or elements together for movement in and out of axial alinement with the ar- -rhature shaft. By reference to Figs.- 5 and 6 of the drawings it observed that the openings in the forks 15 and end portion 14, of the element 13, for the pin 15, are located near the ends and edges of said parts opposite that in which the pin 12, is located, thus the pivot points of the element 13 out of axial pivot point and the extreme portion of said end to con- 'alinement so that it may, have .an easy movement in of a section17- of the vibratory or applicator shaft of th'e apparatus, 'which section is swiveled in thesocket 16 by, means ofa screwl 18, located in the member 19:be tween its forks. The'section 1 7 of the vibratory. shaft is provided at about it's middle with an annular shoulder 20, which abuts the outer end of the l'uik 19,:

'as shown inFig. 6.0'fthe drawings. Since thetoggle link orelement 19 is freeto iturn on the cylindricalporscrewithreaded sockets22and 23, the former being' adapted to engage the screw-threaded outer end of the tion'of the section 17 of 'theapplicator shaft of the-device. .it will be evident'that the rotative movement ofthe toggle will not be imparted to said applicatorshaft. 21 is a sphere or ball, which forms'a part of the vibratory or applicator shaft, andhas diametrically disposed section 17 and the, latter to receive the screw-threaded inner-end of the outer section24 of the vibratory shaft,

which outer section has an internally screw-threaded socket, in which is received the screw-threaded shaft 25. of the applicator 26, which is thus detachably held upon said outer end of the-applicator shaft sofithat it may be conveniently removed therefrom whenever desired, and may be replaced by another applicator or other instrument of any desired kind. l

' Extending from the shell or casing 1 of the apparatus are spaced arms 27, which, ,at their inner portions, form the projecting portion or housing 5 for the balance wheel, and at their=outer portions have or are formed into a collar 28,.which is cylindrical'in shape. Movably located in the collar 28 is a sleeve 29, which is provided with a partly spherical cavity 30 to form a bearing for-the sphere or ball 21 which is located in said cavity. The inner p ortion ofthe sleeve 29 is reduced and externally screw-threaded to engage the outer end of a tubular casing '31, which is located around the members 8, 13 and 19 so as to shield them from entanglement with fabrics and the like, as well as from view.

As is clearly shown in the drawings, this tubular casing 31 extends at its inner end to near the outer surface of the fly wheel, but not so close thereto as to prevent a certain amount of longitudinal movement of "said casing, which is necessary in the operation offthe de -vice as will be presently explained. The inner end of the sleeve 29 isiorined with a flaring opening 32, which communicates with the cavity 30, and is for the reception and operation of the section 17 of the applicator shaft. The outer portionof the sleeve 29 is internally screw-threaded to receive and engage an externally screw-threaded hollow plug 33, which is employed to hold in'place, on the outer portion of the sphere 21, a washer 34, which may be made of flexible material and is provided with an opening 35, for the reception and operation of the section'23 of the vibratory applicator shaft. Secured on the outer portion of the plug 33 is a nut 36, which rests against the outer end of the sleeve 29 and is somewhat larger in circumference than said sleeve so as to rest against the outer end of the collar 28, when the sleeve 29 andtubular casing 31 is retracted, as shown in Fig. 60f the drawings. By reference to Figs, 2 and 4 it will be seen thatthe sleeve 29 has a longitudinal slot 37, in which extends and section or element 23,

movement thereof.

a pin 38 secured to the sphere or ball 21,.which pin and slot will permitof the vibratorymovement of the ap plic a tor shaft, which consistsof the section 17, ball 21,

yetwill prevent rotary The outerend of the handle 2 is provided with a ---bracltet 39, to which is pivotally secured one end of a gripping r regulating lever 40, which is. extended through an opening 41in one of the arms 27, and enj-ga ges at its inner end the tubular casing 31 near its inher end. This lever is normally pressed from the handle by means of springs 42 and 43, the former being secured on the inner surface of the arm 27, through twhich the lever 40 passes, and the latter to the handle.

It will be evident that the vibratory applicator shaft, although not rotating with the outer toggle link or element 19,'still partakes of the pivotal movement by means of which said link or element is thrown in or out of'alinement with the armature shaft 4, a continuous vibratory or gyratory movement being thereby im- 1.85 parted to the applicator shaft so that when the applicator 26 thereon is appliedto the part to be treated, an extremely rapid kneading or rubbingaction is exerted thereon by the applicator, the speed being,-of course, governed by the motor from which the applicator shaft is driven and the amplitude of the movement of said shaft being controlled and regulated by means of the regulating lever 40, tubular casing 31 and sleeve 29, which sleeve, as well as the outer portionof the casing 31, is adapted to move longitudinally in the collar 28, when the lever 40 is pressed towards the handle 2 by the hand of the'operator or outwardly by means of the actuating springs 42 and 43 therefor. It is further apparent that the degree of variation of the links from alinement with the armature shaft, and, con- 0 sequently, the degree of amplitude of the movement. of the applicator shaft, will be governed by the extent to which the lever, casing.31 and sleeve 29 are moved towards the handle and motor shell or casing,

and that this maybe regulated at will by the operator 1 by simply applying sufficient pressure to the gripping or regulating lever. Thus but one hand of the operator is employed in supporting, guiding and regulating the amplitude of vibration of the machine leaving the other entirely'free at all times for other employment and the regulation of such-vibration may be as accu rately and quickly accomplished by releasing or tightening the grip of the hand on the handle as with other arrangements where both hands are necessarily employed. v

From the above description it will be. apparent that, the vibrator-embodying my improvements is of an ex-. tremely simple and inexpensive nature, and is very desirable for use since it affords means for quickly and conveniently adjusting the amplitude-of vibration or gyratory movement of the applicator so that the treatment maybe rendered as gentle oras energetic as desired according to the nature of each particular case, and it will also be obvious from the above description that the device is capable of considerable modification without material departure from the principles and spirit of the invention, and for this reason I do not desire to beunderstood as l-imiting'myselt to the precise formation and arrangement of the sevcral'parts of the vibrator herein set forth in carryingout my invention. 13d
