Be it known that l, Jenn i lvlol /lANis, a citizen of the United tes, residing at Kirlrsville, in the county of Adair and State of Missouri have invented certain new and useful Improvements in Treatment Tables, of which the following is a specification.

My invention relates to improvements in treatment t-ables. One of it's-objects is to provide an improved table having a series of differently adjustable table top sections adapted for use in Chiropractic and other similar treatments. Another object. is to provide table in which the several top sections are supported upon a. substantially horizontal frame which is in turn vertically adjustable relative to its supporting base. Another object is to provide for a variable or adjustable gap opposite the abdominal portion of a patient positioned thereon, and for the angular adjustment and resilient support of the section next to such gap. Another object is to provide a resiliently supported vertically movable section to sklp other object is to provide two s .ira v angularly and vertically ad 'ustalole sections adjacent to each other in position to support the lower extremities of a patient, Another object is to provide a group of three top sections in position to support the bean and chest portions of a patient one. of said sec" tions being angularly adj ustablc the middle section vertically adjustable. and. the rea pivotal connection, a resilient, and yielding vertical adjust- .rinother object is to provide improi ed means to ap Jly' tension to the spinal column of a patient resting on the table. My invention also comprises means to conveniently adjust and lock the respective top sections to their adjusted positions and also certain details of form combination and arrangement, all of WlllClr will be fully set forth in the description of the accompanying drawings in which- Fig. l is a side elevation of a treatment table embodying my invention.

The accompanying drawings illustrate the EJLQ'fGlTGCl embodiments of my invention, in-

l to 6 of which 2:. represents the sup- 1 porting base, in which is formed the cylindei: oil hydraulic lifting mechanism; B reg t;resents standard or plunger seated in d cylinder and vertically adjustable relative thereto by means of a hydraulic pump located in the standard B and actuated by the pump handle 2 to pump a fluid from a chamber in the standard 13 into the space beneath the standard B in the cylinder. of the base, or at another position of the handle 2 to release thefl'uid from the cylinder and allow. it to How back to the chamber in' the: standard thereby enabling the standard B to be elevatedor lowered without noise or vii/ration objectionable to the patient.

Mounted upon and firmly secured to the; standard B in a substantially horizontal position and parallel to each other are tworods or supports l) upon and relative to which the several tabletop sections E, F, :l'. H and l are mounted, preferably in theitollowing manner. i

The section E for a majority of treat ments is designed for the head ofthe patient to rest upon. and is preferably divid'edcentrally and longitudinally into two sections 4, and 5 which are adjusta-lfiily mounted upon a frame 6 so as to be adjustable thereon to and from each other to openand close a central longitudinal gap between sections. 4: and 53. Whenthe 1 patient lies face downward" the gap is preferably open so that face of the patient is in the gap between the sections 4 and 5 and the weight of the head resting upon the edges of the sections, thus maintaining the spinal column in its normal posit-ion free from strain due to turning the face to one side, and the patient can conveniently breathe through the gap.

The sections 4 and 5 have rods 7 attached thereto by brackets 8, and said rods slide endwise in perforations in the frame 6 and also in brackets 9 attached to the sections 4 and 5. Acrank shaft 10journaled to frame 6 has two links 70, Z attached to crank pins thereon, and said links at their opposite ends are connected to brackets 11 on the sections 4 and 5 so that a half revolution of the shaft 10 in one direction or the other by its operating lever 12 will force the sections 1 and 5 together or apart. The brackets 8 serve as stops in one direction and stop members 14 attached to the sections 1 and 5 serve as stops in the-opposite direction to engage the frame 6- and. limit the movement of sections 4 and 5 and to lock them at each extremity of their movement, due partly to the crank shaft 10 reaching a position on dead center at each' extremity of said movement.

The frame 6 is pivotally attached at 15 to 1 ears projecting up from a standard 16 mounted upon the horizontal rods 1). The standard 16 is preferably slidably adjustable along the rods D and locked to any desired position by means of locking levers 17'. In order to adjust the top section E and frame. 6 to any desired position of angularity turning on axle. 15, I provide a cross bar 18 carried by and adjustable on the rods which cross bar has a gravity latch member 21 pivoted thereto and provided with a vertical rectangularrecess to receive a rectan-- 'ular bar 19 which ispivoted at 20 to the ram e 6. The gravity latch 21. serves to antomatically grip the bar 19 to prevent it moving downwardly while leaving it free to be drawn upwardly through the recesses in the latchmember 21. To lower the bar 19 through said recess the hand lever 22 is depressed to lift and release the latch member 21. The frame 6 carries a bracket E24 havinga rectangular horizontal recess and a hand wheel to detachably connect a spine stretching attachmentto the frame 6. I The spine stretching attachment comprises'a shank :25 to enter and be locked in the recess of bracket 24, a vertically adjustable shank 26, a threaled sleeve, a screw rod 27 having a hand actuating lever 28, and a cross bar 29 carried rotatably by the screw rod to be hooked into a flexible: harness'attached about the throat of a patient, thereby enabling a strainto be applied to the spinal column tending to separate the sections thereof;

The standard 16 is also provided with a loop shaped bracket 30 which serves as a support for the top section F which ifdesired may be of somewhat less width than the other sections. An axle 31 is carried by the bracket 30, and an axle 32 is carried by ears'attached to the top section F. The

axles

31 and 32 are passed through perforations at opposite ends of links 33 to connect said axles together and hold them in parallel alignment. Alpair of cams 34 and an operating lever 35 are rigidly mounted on the axle 31 and said cams engage shoes on the under face of one end of section F toraise and lower that end of section F by partially rotating the axle 31. A pair of cams 36 and an operating lever" 37 are rigidly mounted on the axle 32 and said cams engage shoes on the bracket 30 to raise or lower the opposite end of section F, thereby providing four positions for section F; anrelevated and low position, and two positions inclined in oppo' site directions.

The top section G is supported upon an arm 38 to which it is secured by bolts or screws. The arm 88 in turn is forked and pivotally supported upon an axle 39 carried by the standard 16. In order to yieldingly and resiliently support the section G, a coiled spring lO is attached at one end to the bracket 30 or looped over the center of axle 31 carried by bracket 30. At the opposite end spring 40 is attached to a sliding car riage 41 which is guided between two arms 42 along which it is moved by means of a of member 1-7 rests upon the end of member 4:6 and provides for" adjusting the top section to different positions vertically. The spring 40 tends to lift the arms 1-2 with greater or less force depending upon the position of the carriage 41, and this lifting force is transmitted through the members 46 and 4:7 to the arm 88 and section G. Where it is desired to lock the section G rig- 1 idly to any position a locking bar 19 pivotally attached at one end to arm 38 is clamped rigidly at its opposite end to one of the bars 12, by means of a cross bar and locking lever 50. i

The top section H is designed to be adj ustably supported relative to the rods D at any desired position intermediate of the top sec tion G and I, but usually relatively closer to the section I, and is adjustable jointly with said respective sections into several different operative relations.

eashes In Figs. 1 and 10 I have illustrated one form of section H, which I considerthe pre ferred form, and in which the top may be supported in substantially rigid positions, and also resiliently supported as desired, while in Fi s. 6, 7 and 8 I have illustrated a modified form of section H having substantially the same top adjustments, except the resilient supporting feature. For most purposes the top sections H and H are adapted to be used interchangeably one for the other, on the same table, although'the section H having the resilient supporting feature is preferable where only one type is to be employed.

The top section H as illustrated in Figs. 1 and 10 is pivotally attached by a hinge member 108 to one end of the links 109, which are employed in pairs, and also to one end of the links 110 also employed in pairs. At the opposite ends links 109 are pivotally connected to ears 112 projecting from a cross-bar 11d slidably mounted upon the frame members D. The cross-bar 114 is preferably provided with recesses through which the members D slide to adjust the cross-bar 114 to any desired position and afterwards locked to members D by locking levers 115.

A crank shaft 116 is jonrnaled transversely to members D in hearings in crossbar 11%, and the opposite ends of links 110 are pivotally connected to the crank arms 117 carried at opposite ends of shaft 116. An index and locking plate .118 having a series of perforations to receive a sprin locking pin 119 carried by an extension or one of the crank arms 117 provides for rotating the shaft 116 to raise or lower the top H at the right hand end, and to lock the shaft 116 to any desired position of ad justment. A slotted arm 120 is pivoted at one end to the links 110 and near its opposite end is connected to the top H to support the left'hand end thereof by means of a tubular section 121pivoted to the arm 120, and a threaded section 122 pivoted to the top H and telescoping into the section 121. A nut 123 threaded on section 122 rests against the end of section 121 to adjust the left hand end of the top relative to the arm 120. A spring 124 is attached at one end. to the hinge 109 and at its opposite end to a block 125 adjustable endwise relative to the arm 120 by means of a screw rod having a knurled head 128. The spring 12d tends to lift the arm 120 with greater or less force depending upon the position of the block 125, and the

sections

121 and 122 transmit this resilient thrust to yieldingly support the left hand end of the topH. A locking bar 126 pivotally connected to the top H and adapted to be locked by lever 127 to arm .125) serves to hold the top H in any desired. position, but with a retained caposite ends pacity to yield downwardly to an excess of pressure from above, due to the elasticity of spring 12 1 and a downward movement of arm 120, and section 121, which causes the nut 123 to lift from the end of section 121.

When the locking bar 126 is released from arm 120, the left hand end of top H is entirely supported by the resilient action of the spring 124-, and when the bar 126 is locked to arm 120, the left hand end of top H is prevented from rising above a certain limit, but is enabled below that point to yield more or less readily depending upon the position of the block 125. The foregoing is true also as to the top section G. The top section H is thus vertically adjustable through the vertical thrust of the links 110, and also resiliently supported relative to any of its vertical. positions of adjustment.

The top section l-l illustrated in Figs. 6, 7 and 8 has four ears on its under face to which four crossed supporting links 52 are pivotally connected one end. At the opposite end links 52 are pivotally connected to four ears projecting from a cross bar '54 slidably mounted upon the frame members D. The cross bar. 54: is preferably provided with recesses through which the members I) slide to adjust the cross barthe resilient adjustment of.

54 to any desired position thereon aft-er which the cross bar is locked to members D by locking levers 55. T ransversely to members D are crank

shafts

56 and 56 journaled near their opposite ends in bearings at op- Y of cross bar 5%. at opposite ends of the respective shafts 56 are connected by

links

58 and 58 in pairs to the cars 51 of section H. The cross bar 5 1 is provided with index and locking plates 59, each having a series of perforations to receive a spring locking pin 60 carried by an extension of its co-acting crank arm 57. to enable the crank arm to be locked to any desired angle of adjustment. By adjusting angularly the respective crank arms 57 and the shafts'on which they are mounted the links 58 serve to raiseor lower the top sec,- tion H at either or both ends and thus to secure a variety of positions of adjustment for the top section H relative to the frame D on which it. is mounted, as indicated in full and dotted lines. The locking pins serve to retain the top section Hin its adjusted position, and rross braces not shown connecting the respective pairs of links 52 enable the top section H" to resist strain or thrusts laterally.

The top section 1, Figs. 1, 6, 7, and 8, is supported upon and above a cross bar 61 similar to cross bar 54, which is adjustable longitudinally upon the members D and locked thereto by a locking member 62. A rectangular frame formed of

cross-rods

63 and 6 1 and longitudinal rods 65, is connected Crank arms, 57

to the cross bar 61 by means of crossed links 66 and. 67 in pairs. The links 66 at one end are pivotally connected to the cross-rod 70 and 71 rigidly secured thereto, and said cross-bars 70 and 71' are perforated to receive the rods 65 upon which they are slidably ad ustable. A. screw rod 72 having a hand crank 73, is journaled 1n the cross rod 64: and threaded to the cross bar 71 to pro- -v1de for positively ad usting the top section I along the rods 65. Members 74!; detachably seated in sockets attached to the under side of section I and provide for attaching the ankles of a patient by anklecufl's to the members 74.- when required, as for instance to stretch the spine, which may be effected by attaching the patient near opposite ends to

members

29 and 7 1, whereupon the stretching may be effected by screw 27 or by screw rod 72.. but is preferably effected by partial use of each, whereby the weight of the patient has less inl'luence'iupon the stretching operation, and results ina more even and uniform-resultthan where the force is all applied at one end.

Crank shafts 76 and 77 journaled at opposite ends tocross bar 61 are provided with cranks'78 connected by means of

links

79 and 80. in pairs respectively to the cross rods v63 and-6 1 to provide for adjusting the top section I to various positions, where locking pins 81 engaging inde::: plates 82 serve to lock the top'section to its iuiljlisted position as heretofore described for see tion H; I

As illustrated in Figfll' the top section I is resiliently supported substantially as heretofore described for top section H, but

With the resiliently supported portion of the top section at the right instead of at the left hand.- The links 66 and 79-correspond to links 109 and 110 of Fig. 10 andthe bar 120, spring 12 1 and members 121. 1.22 123, and 126 correspond to parts 121,122, 123, and 126 of 10, being operated substantially as described for Fig. 10. The two sections H or H and "I or I are thus enabled to be relatively adjusted and jointly employed for a variety oi. treatments both with and independently of the other top sections, particularly with reference in its lower position, is clamped to plunger 96. Then the pump lever 98 is employed ed to an inclinedor nearly vertical posi-' tion to facilitate receiv ng" and discharging The eeroa adjustments are substantially the same as heretofore described. i

As illustrated the mainframe D is pivotally supported. upon an axle or shaft '35 which rigidly attached to two

coupling members

86 and 87 through recesses in which the frame members D are adjustable endwise and locked by hand wheels 88. The coupling members 86 have grooved concentric pulley segments 89 to which chains or cables 90 areattached at.

At the upper end plunger 96 has jaw 99 and set screws 100. to receive and grip the members D. .fesplit ring 1025011 the plunger 96 may be clamped thereto by l'iand lever 103, or released and allowed to rest on the upper edges of cylinder 97. The oppositeends ofchains 90 are attached at opposite sides of plunger 96 to the ring 102 and are guided over the idler pulleys and 106. In order (to bring the frame D from a' horizontal to a nearly vertical. positionto re-. ceive a patient, the set screws 100 are released, and. the ring 102 with the chains 90 in taut position, and plunger 96 olun 'er cavit to elevate plunger 96 whichpulls on the chains 90 and swings the frame D through the arc of a circle on. the shaft 85 as a center. After the patient is'in position on the nearly vertical table, plunger 96 is lowered allowing the frame D to resume a .cond hydraulic plunger 96 seated v substantially horizontal position with the frame D rising in the jaws 99 where it is secured and the ring 102 "released from plunger 96. The

respective plungers

91 and 96 may now be independently or jointly adjusted to secure any desired elevation or inclination oi? the frame D.

The mechanism herein illustrated and described is capable of considerable mod'r fioation without departing from the princi ale of my invention.
