To all whom t may concern: y f 'i Be it knoivn that LJOHN'V. MoMA'NIs'a citizen of" the United States, "r'esidii'ig at lirlrsville, in the county ofidair and 'State of Missouri, have invented certain new andf Auseful improvements in vrllreatii'ie nt-lables, of which the olloi'ving'is a speciiication.

vide an improved treatment tablehavinga' plurality of oscillatable tabletop," sections, another object is tofprovide improved. lock,- ing mechanism to loc-k1A the top sections ii'il any one of a variety ofpositions.Another i object sfto provide., improved means Vto resiliently support the oscillat'able sections."

inother object is toV provide mechanism tof-1y 'take up lost motion and provide4 Aagainst undesirable vibrations. V'Another object is to' provide against the vibrationandfsvvav, ing movement of movable parts carried-'by the o scillatableV top sections. Anotherobject is to provide improved adjustable means to secure a patient in' position on the table top. v l

My invention also comprises certain desy tailsoform combination and arrangement,

'tached to the top section V-F and are provided lwith bearings for the vends ofthe axle; 16, and feed screw thereby providing for see Vv'Figi 8, to whichtensioning springs 28 ai'e each; attached at one end. At the-opposite ends'sp'rings 28 are attached to eye-bolts 291passiiigTV through lugs projecting from the cross bar 21 yand the desired tension applied by adjusting the nuts 30. Stops 31 on cross i bar 21 positively limit the movement of the j projection 27, Abut the springs 28' normallv serve to hold the top section ina horizontal position and to resiliently limit its movement and return it to position when deflected therefrom. y

In order to' positivelyu lock the top section! F against movement upon the axle 16y I pro-' vide lugs -32 von the cross bar 20 and metal shoes 35 on the underface of the top section.

' Allocking member 33V slidable endwise on tlie axle A16 by means of a hand lever 34,

is provided with projecting arms 36 to be interposed with a close it between the faces of the respective lugs 32 and the respective shoesY to positively and rigidly lock the topV section againstrotation on the axle 16 relative to frame 12. In order to adjust the arms136 to accurately engage between the lugsv 32 and'shoes 35 to prevent lost motion and consequent objectional vibration and also to compensate for wear at these points I preferably split the arms 36, see Fig. 10, for a portion of their length and provide a tapered screw 37 ,orother equivalent means toA vaccurately adjust the dimensions of the arms 36 from time to Atime as may be required. Y Y j vIn order to resiliently tension the movement of the tabletop section F upon its axle 6 I provide springs 38`and 39 each attached atone end to one end of the cross-bar 11.

The opposite `ends of said springs are at-, ltached to .eye-bolts 40 passing through lugs 41 projecting ffromtlie head E and to which eye-bolts and springs tension isapplied by means of nuts42. The effect of the springs 38j and 39is to normally and resiliently hold theitop section F in an intermediate position and toretuin it to such position a-fter'havingbeen deiiected therefrom. Said'springs also tend to counterbalancethe overhanging weightY of .thetop section onk the ax-le`6 and to .prevent crampingof saidfaxlefin its bearings. from such cause.

Inorder to lock the top ysectionF'lto lany usted position upon its; axle 6, I provide a pair'of brake shoes 43A and 44 which restl upon the head E andare guided by a raised rib 45 thereof.

An operating shaft 46 is f "journaled at 47 to the head E and provided i 4S`enables the shaft 46 lto be conveniently turned to lock the brake shoes upon the pleriphery of the segment 9 to hold the top section and its axle 6 rigidly in any desired position. i

yIn order to resiliently support the Ytop section F relative to its axleV 14 I 'provide a slotted `frame 49V which is pivotally connected to the lower end Vof the axle 6. One or Ymore springs 56 are attached at one end tothe head 8, preferably by looping them at one end over the axle 14. At the opposite endsprings 50 are attached to a carriage 51 movable along the frame '49 by means of a screw rod actuated by means of cran'k'arm 52, whereby the tension tend-V ing tollift theframe" 49 may be varied dependingv upon the posit-ion of the carriage 51.

The upward thrust 'of frame 49 is transmit-1 ted to the cross bar 19 of the frame 12 Vby means of a tubular member 53 pivoted at one .with right'A and left hand threads to engage end to frame 49; an eye-bolt 54 pi-votally attached tothe cross-bar 19V and telesoopical'ly connected to the member 53; and a nut v54 threaded to the shank of the eye-bolt and resting upon the end of member 53. The top section F is thus. resiliently supported. relative to its axle 14 iii a substantially horizontal position, and the tension of springs 50`may be varied tosupport the weight of different patients thereon. In order to lock the top section F in a substantially rigid position relativeY to movement upon its axle 14 I provide a locking bar 55 pivoted at one end to a V collar rigid on the frame 12, and slotted at t'he opposite end and adapted to be locked by a clamping' theend of the tubular member 53. f

-The feed screw 25 is threaded into th cross bar 18 of frame 12 so that rotation of said screw causes the top section F toy travel for a limited distance endwise on the frame 12. This endwise movement provides for applying tension to the spinal column' of a patient. A Ybar 56 pivotally attached at its center to the under faceiof top section F provided with sockets at opposite ends linto which detachable clips 57 are inserted` to provide for. attaching' the ankles of a1 pas frame 61-by reason. of the stops 65'and 67,-

and the dead center positions of crank tient by ankle cuffs to said clips, andas the Vtop section-F sways horizontally the bar 56.v is free to turn upon its pivot and evenly ad just the strain upon the ankles of the patient. ln order to prevent displacement or a swaying movement of the crank arm 26 and screw 25 l preferably provide a spring actu- 5' ated plunger 58, see Fig. 5, to bear upon the screw shaft 25, the tension on said plunger being adjusta-ble by means of a` screw 60 bearing upon the spring 59, `to force it against the plunger 5S.

The top section H is pivotally and resilientiy supported 'relative to the pedestal as .f heretofore Y A Vand identified with like reference letters eX- described for the top section l?,

cept that the cross bars 22', 23l and 2li corresponding to the cross `bars 22, 23, andv24. are not attached directlyto the top sectionv H but are attached to a rectangular metalframe 6l upon Which-in turn the separate and separable segments 62 and 63 compos,` ing theutop section fl are adjustabl'y frame6lin one direction by contactingv therewith, and the stop members 67 contact with frame 61 to limit the movement inthe opposite direction .A crank shaft 68 is l journaled -in a Vbracket"'attached to frame 6l", and is pivotally connected to one end of n eachof the links 69 and 70; The opposite ends of the links yare pivotally connected to the blocks 7l and '72 attached`v respectively to the segments 62 and 63. LA half rota-` tion of the'crank shaft 68` shifts-the centers on'which' the links are pivoted to the crank shaft 68 from one point of dead center -to theaotherand moves the segments `62 and 63 to and from veach other,.lockingthemat.
