i Be it known that I, IRvING A. WESTON, o Syracuse, 1n the countyfof Onondagaand State of New York, have invented a certain new and useful Implrovement'in Massagev In-v struments, of lwhic the vfollowing is a speci- 1 Theffm'ainobject ofiny invention is to pro# vide a 'simplified form of power-driven massagerinstrument or apparatus for mechanically performing the various operations which are usefulin massage treatments.v

It vconsist-s in a novel arrangement of parts in simple yet efficient form adapted so that the'length of stroke or `degree of vibration willof the operator..

Referring to vthe accompanying drawings,

. Figure 1 is a longitudinal section lof massagev` instrument constructed `according to my inf vention; same on lines-XX of Fig. 1'. I

Fig. 2 yis Aa transverse section of j 3 is a view ofthe main shaft detached. s. 4, 5,6, `and 7 are 'details of the parts use hereinafter more fully described. V A In carrying out the objects of my inven tion T provide a cylindrical'metal case a, with a radial tubular extension b near one end of said casing a, onstitutingl a handle by which the'instrumen is manipulated, and is formed with alengthwise openingtherethrough from end to end, O'n'e end, opposite tov that near which the tubular extension b is located, being smaller than the o posite end and is closed by a ca c', while tlhe larger end of the casing is close by a cap c.

Theinner end of the tubular extension?) communicates with the 'interior of the cas-.` ling a, and in thisextension is` guided a reciprocatory plunger'e, having a reduced youter end which is guided ina suitable screW-cap-fitted inthe outer end of the tubular extension band adapted lto support a beater d, the latter being fitted upon the reduced end kofthe plungere andl 1s there-L and is therefore held in lace and adjuste by a cap cf. This ring f as an opening theresuitable r screw-bushing.

through from end to end axially ofthe casing a, the inner end ofthe opening being smaller tially-s herical bearing-face, in rwhich, is seat- -ed a bal member g, and the outer end of the ring f is threaded interiorly and receives a s'also provided with a partially-spherical bearingface forming' a continuation of the inner spherical bearing-face of the ringj" vand than its outer end and is formed with a par- I (See-Eig. 5.) Thisv serving to retaintheball g Withinthering f',

at the same time t'o permit said ball to lbe re- `moved y'and reinserted through the k larger openend of the ring f The opening in the end ofthe casing in which the cap c( is fitted is slightly larger than the annulus m and rin f to permit these 'parts to be readily place in operative the caslng.

easy S dingfit a sleeve j. This is ofconsiderably less llength than the vdistance bef tween the annular shoulder mand inner end ofthe cap c' t'opermit said 'sleeve to be moved position or removed from 4 The interior boreof the casing a between ,thev annular shoulder m and cap c is'preferendwise or axially ail limited distance for a' purpose vpresently described, 'such endwise movement being effected throu h Athe me` which is 1 dium of 'a -suitable handpiece screwed in the inner` end of the sleeve j', as best seen in Fi 1, and projects outwardly through aslot in the casing c, said slot k bein of greater len th than the diameter of lays in said slotthe andpiecey K W 'ch and, together With'the si es of the slot, prevent rotation of the sleeve j. j This sleeve j has a central lengthwise bore, in which 1s j'ournale'd a rotary shaft h, having sliding connection with the adjacent end ofthe flexi ble driving-shaft t, as best seen in Fi .1.

The end of the shaft h nearest the ring f is enlarged at o to ar greater diameter than the interior diameter of the sleeve j" and abuts againstthe adjacent endof said.sleeve,.while the opposite end of said shaft is reduced in diameter andreceives a suitablezannulus or Ioo collar, which Iis also of larger diameter than the adjacent face ofthe annular enlargement ,o atone side of its axis 'of rotation', as best seen in Figs. 1 and 3, and projects endwise from said annular enlargement in the incline ringf and'plunger e,'toge`ther With thebeater d,-to reci rocate through varying axial distanees,W chisuthe-.primar object sought.

vIt is evident from :the oregoing description that the sleeve-j( and its inclosed shaft h are locked against'in'dependent .axial movement, although the shaft his free to rotate andthe 'sleeve is held against* rotation by the handpiec'ek.-

Iam aware Ithat 'I am not the rst to provide means broadl ifor reciprocating a beater, :sueh'de'vices eing shovvn in the patents to Bihlmaier, No.- 688',5'81,1December 10, 1901, and lalso inChurch, No1 743,147, 4November 3,' 1908 but vI believe I am the first to provide arotating-shaftf--With a rigid s indle projecting from one end of the s aft throughA- a b'all which is mounted in a par `tially-spherical--bearing attached to a beater plunge1",a'ndIfal'so bel'ifeve .that4 I am the first to'movesaid shaft, together' with its non-rotatable sleeve,4 endw-ise or axially for the purpseborlmoving the eccentric spindle through 't eI a Inoperation'the'shaftfh'and its eccentric s indle j are rotated through a medium of the s'aft 'f, 'reciprocating motionv being transvferred tofth'e plungere through the medium of the eccentric spindle y', 'ball-g, and ring f', and the degree 'of such movement is controlled by the handpiece 1c lmoving back and forthv in the slot 7c andl imparting similar movement tothe shaft h, sleeve j', and ec! centric' spindle y', the kaxis lofvvhich latter is disposed -at an angle With the .axis of' revolution'i'1 said shaft, with itsfreeend at one side of said axis, Iso that as the-'shaft h and spindle j-are's'hifted oaelrl andfo'rth the degree of the movement of-tghe' beater i's correspondingly varied;

What I claim as new, and desire to secure by Letters Patent, 1s-

1. In a massa e lnstrument a casmg con- I stituting a hand e having a lateral tubular extension, a' plunger movable radially in said extension, a beater on the outer end of the plunger, a ring pivoted to the inner end of the plunger and provided with a partially-spherical inner bearing, a ball j ournaled in said bearing and rovided with a central opening, a non-rotatable-sleeve slidable endwise in the casing at ri ht angles to the movement of the plunger,"a andpiece attached to the sleeve and extended to the outside of the casing, a rotary shaft journal'ed in said sleeve and movable endwise therewith and a spindle having one end. rigidly united yto thes'haft and extending endwise therefroml at an angle viti its axis and through the opening of t e 2. In a massage instrument a casing, a rotaryshaft movable endwise Within the casing, means to move the shaft endwise, a spind e projecting from'the end of the shaft at an angle with and across its axis, a non-rotatable ring, an oscillatory ball seated in the ring and provided with an opening receiving. the free end of said spindle, and a plunger attached to the ring and the beater on the plunger.

.3. In a massage instrumenta casing constituting a handle and provided with a lateral tubular extension, a plunger movable radially in said extension, a'beater on the plunger, a non-rotatable ring pivoted toy one end of the plunger, a ball journaledi in the ring and provided With a diametrical opening, a rotary shaft movable endvvise Within the casing and provided with a rigid spindle projectin endwise at an an le With lts axis and slidab e endwise with sa1d shaft through the opening in the ball, and means for moving said shaft endWise.

In testimony whereof I have hereunto signed my name, in the presence of tWo attesting wltnesses, at Syracuse, in the county of Onondaga, in the State of New' York, this 24th day of February, 1904.
