UNITED STATES EDWARD OVERMAN AND EDWARD Pf-BLANCHARD, or Los ANGELES, CALIFORNIA.

CHIROPRACTIC. TAIBLE.

Application filed July 25, 1923.. Serial No. 653,697.

To all whom it may concern:

Be it known that we, EDWARD OVERMAN and EDWARD P. BLANCHARD, citizens of the United States, residing at Los Angeles, 1n the county of Los Angeles and State of California, have invented certain new and useful Improvements in Chiropractic Tables, of which the following is a specification, reference being had to the accompanying drawings. 1

This invention relates to articles of furniture, and particularly to what are known as chiropractic tables.

The general object of the invention 1s to provide a table which is particularly adapted for use by chiropractors and which will permit a very large number of manipulations of the patient to be made thereon.

A further object is to provide a construction of this character in which the abdominal support is supported from the frame of the foot section of the table andgiven proper resilient resistance to thus absorb the shock of thrust to the patient.

A still further object-is to provide means for raising the foot rest with the supports to thereby support the foot rest at various elevations, and provide'means whereby the foot rest may be readily released at any de-" sired time.

Another object is to provide a head rest which is in two separable parts, which may be raised or lowered, and in which the cushions are so supported that they may be placed together or separated as desired.

Still another object is to so support the abdominal pad that it is held horizontal or level as it is depressed under thrust.

A further object is to provide an abdominal support with resilient means resisting its downward movement, means for tensioning said resilient means, and means for locking the abdominal support in its raised position.

Still a further object is to provide a breast pad which is so mounted that it may be held either in a rigid position or that it may move downward under thrust. I

Another object is to provide a sectional abdominal support formed in a plurality of sections so constructed that the sections may be released for downward movement independently of each other, the cushionsofthe sectional abdominal support being so constructed that they will be resiliently supported. I I

Still another object is to provide a device of this character which is adapted to be folded upv into very compact form where. the table is to be carried from place to place,

and in this connection to. provide a chiro-- practic table of this character which has the essential features as regards the mounting of the head rest, breast support, the primary and secondary abdominal supports, and foot rest, referred to. I r

Other objects will appear in the course of the following description.

Our invention is illustrated in the accompanyin drawings, where'inz-- Figure 1 is a side elevation of a fixed or rigid chiropractic tabIecQnstructed in accordance with'ou'r invention; v

Figure 18 is a section on the line 18-18 of Figure 17; I

Figure 19 is a fragmentary perspective view of the extremity of the beam section 110 looking from the inside;

Referring to the drawings, and particularly Figures 1 and 2, A designates the head supporting section, B the breast supporting section, G the abdominal supporting section E the abdominal and le supporting section, and F the foreleg supporting section of the device. The frame of the table consists of the longitudinally extending angle irons which at their ends are engaged with the vertical angle iron legs 11, there being filler blocks 12 disposed within the lower portions of said legs. Transverse braces 13 connect the legs 11. A trans verse brace 14 connects the beams 10 just beneath the abdominal support.

Extending upward from the beams 10 are the supporting braces 15; The upper ends of the legs are connected by a transverse brace 16, and attached to the upper ends of the supporting members and the upper end of each adjacent leg is a web 17 of sheet metal or like material which extends transversely across the frame at the rear edge of, the supporting member 15. The upper ends of the supporting members 15 are connected by a transverse rod 18 having upwardly extending cars 19 riveted thereto, and extending through these ears is a pintle 20. The frame which supports'the head cushions consists of a cross piece 21 and side pieces 22, these side pieces being pivoted at their upper rear corners upon the pintle 20. Thus this frame composed of the members 21 and 22 can be tilted upon the pintle 20. The member 21 has an inwardly extending flange 23, and resting upon the frame are the two cushions 24, as illustrated in Figure 2. Each cushion, as shown in Figure 3, has a clip 25 attached thereto which is bent around and extends beneath the flange 23. The cushions are mounted upon wooden pieces 26, and attached to the inner faces of these pieces, as illustrated in Figure 5, are the U-shaped members 27 forming depending ears through which the rod 20 passes.

It will thus be obvious from Figure 5 that these two cushions 24 may be adjusted toward or from each other, and it will be also obvious that the frame supporting these cushions may be tilted upon the pintle 20 so that the rear end of the frame may be raised or lowered.

For the purpose of holding the rear end of the frame in its vertically adjusted position, we mount upon the side pieces 22 the transverse rock shaft 28 having a medial crank 29 and having downwardly extending spring arms 30, the lower ends of which are turned slightly forward and are adapted to engage in ratchet recesses 31 in the filler pieces 32 which are carriedwithin the angle iron legs above the longitudinal members 10. To the crank 28 is attached arod 33 supporting a handle which extends out through the member 21 and is provided with a head and between the head and the member 21 there is disposed a coiled compression spring 34. Thus this rod is urged outward and the arms or pawls are urged into engagement with the ratchet recess-es 31. These arms or pawls 30 are yieldingly forced into engagement with the ratchet recesses 31 and thus after a depression of the'head section the head section may be raised to any desired height and the pawls '30 will spring into locking position in the recesses. hen it is desired to lower the head rest, the handle rod 33 may be forced inward, rocking the shaft and shifting the pawls out of engagement with the ratchet recesses, thus permitting the lowering of the head rest or support.

Mounted in the supporting members 15 adjacent the cross bar 18 is a transversely extending pintle 35. The breast supporting section B includes a cushion 36 and supporting board 37 therefor, and attached to this board is the supporting frame 38 which is angular in side elevation, as shown in Figure 3, and also angular in cross section, the downwardly extending arms of this angular frame being connected by a transverse web 39. The board 37 is attached to the rearwardly projecting arms 40 of this frame.

Attached to the cross bar 39 forming the lower end of the angular frame is a member 41, to the extremities of which are attached coiled springs 42. These springs are attached to the inwardly turned ends 17 a of the sheet metal web 17. Thus it will be obvious that these springs will resist any downward movement of the breast section B. The breast section, however, may be forced to the dotted line position shown in Figure 3a-gainst the action of these springs.

Means are provided, however, for holding this breast section from depression, this means consisting of a transverse rod 43, this rod having arms 44, the ends of which ext-end transversely through the side plates 17, one end terminating in a radial handle 45. When this rod is turned to the full line position shown in Figure 3, it will prevent any further depression of the breast supporting section, but when this rod 43 is turned to the dotted line position it will permit the full depression of the breast supporting section B against the action of the springs 42.

Between the transverse brace 14 and the iii front legs 11 there are mounted upon the side bars the upwardly'extending'niembers 46 which are connected at their ends by a transverse brace, Attached to the uprights 46 and the upper ends of the legsll is a web 47, the upper edge of which is inwardly turned, as at 48. This web extends across the foot end of the table, as at 49,

the upper edge of this web 4-9 being in wardly turned, as shown in Figure 3. Mounted just in front of the uprights 46 and resting upon, the inwardly turned flanges 48 is a board or like supporting memporting frame.

porting cushion 5i whose'rear portion as her 50 which is rigidly connected to the sup- This carries a thigh supshown in Figure 2, is formed with a triangular recess 53. spring leaf 54 is attached to the under face of the board 50 at its rear edge and extends out beneath the portions 55 of the cushion on each side of th'etriangular recess 53. A leather pad 56'is disposed beneath the triangular cut out or recess 53 and extends over this leaf spring.

Hinged to the board 50 is a foot supporting board 57, the hinges being designated 58. This carries a cushion 59. The board 50 is supported upon a transverse brace 60 and the rear edge of the board 5'? is also supported upon this transverse brace 60.

For the purpose of raising and lowering the foot supporting board 57, this foot supporting board is recessed transversely adjacent its upper end and provided with the transversely extending rock shaft 61, this rock shaft being held in place bythe longitudinal angle irons 62 which additionally brace the board 57 At one or both ends this rock shaft 61 is provided with a handle 68, and attached to the rock shaft are the down-- wardly extending resilient arms'or pawls 64 whose lower ends'are outwardly turned and adapted to engage in ratchet recesses 65 disposed in filler pieces 66 mounted in the angle iron legs. shifting the handle 63, the pawl 64 may be thrown out of engagement with the ratchet recesses and then the foot piece may be raised to any desired angle and lowered to any desired position.

Pivotally mounted upon the transversely extending pintle 67 a are the longitudinally extending angle iron levers 67 which extend beyond the sectional abdominal sup port 55 and at their rear ends are connected to a transverse rod 68 mounted in the clownwardly extending flanges of longitudinally extending angle irons 69. Aboard 70 is mounted upon these angle irons 69 and car.- ries the cushions 71 for the abdominal supporting-section. Attached to the under face of this board, by flanges 72 is a depending guide rod 73 which extends through the cross bar 14: and carries a nut 7 4 at its lower.

It will thus be obvious that by,

end. It will be seen that under these circuinstances a depression of the member 67 will cause the rod 73 to slide through the member 1a and hold the abdominal supporting cushion in a! horizontal position at all times and under all circumstances.

Attached to the angle lron levers 67 ust rearward of the rod 66 is a transversely'exs tending member 75. The rear ends of these levers 67 are connected, as at 76, andin order" to hold the abdominal support 71 yieldingly raised we connect to this cross bar 76 the coiled contractile spring 77. The lower end of this spring is connected to a crank 78 by a clip 79. This crank 78 is mounted in pins 80 attached to the side rails 10 and this crank is provided at one or both ends with a handle 81. By shifting the handle in one direction, it will be obvious that the lower end of the spring 77 will be shifted downward, thus increasing the tension-on the spring.

The upper flange of one angle iron 10 is formed with teeth 82, the handle having a flange adaptedto engage these teeth to thus lock the handle inadjusted position to thus lock the spring in its tensionedposition. By shifting the handle inward against its own resilience, it will disengage from the teeth 82 and permit the spring to compress, thus relieving the tension on the levers -67.

Disposed within the rectangular frame formed by the levers'67 and the cross piece r 76is a second frame rectangular in-plan,

formed of the levers 83, these being slightly angularlongitudinally, as shown in Figure 3, and at their rear ends being attached to and supporting a, transverse board 84: which LOU is disposed below the cushioned portion 55.-

These levers are connected at their forward ends by meansof a transverse portion 85. Pivotally mounted upon a cross rod or pintle 86 are opposed supporting levers 87 which are angular longitudinally and cross sectionall'y, and the rear ends of these levers support the section 88, which in turn supports the'rear ends oflthe cushioned por-' tions 55 and the forward end of the sprin.

O leaf 54c. -The free ends of these levers '87 extend forward and e are connected by a transverse cross bar 89, and-1n order to'hold these forward ends of the levers depressed and the section 88 raised, we mount in the 88 supports the forward end of the spring- 54 and when it is up prevents this leaf spring from flexing.

In order to hold the levers 67 from de- .pression, We mount upon the uprights 46 the transversely extending rod 91. The ends of this rod are cranked, as at 92, and extend out through the uprights 46 and this rod is provided at one extremity with the crank handle 93 whereby the rod may be shifted. This rod 91 is disposed below the lever 67 and when the rod is swung upward it moves into the recesses 94 formed in the levers 67 and locks therein. It is urged into these recesses by means of the spring 95. When the handle is turned completely around so that the crank extends upward and toward the head of, the frame, the rod is then out of the recesses and under these circumstances the levers 67, or in other words the frame supporting the abdominal supports 70 and 71, may be fully depressed against the tension of the spring 77.

For the purpose of locking the. levers 83 with the forward ends thereof depressed and the rear ends raised to thus hold the section 88 pressed upward, we mount upon thewebs 47 the cranked rod 96 which is provided with ahandle 97 upon the exterior of the table. Vi hen this handle is turned to the position shown in Figure 1, it causes the cranked portion of the rod to extend downward, as illustrated in Figure 3, and bear against the upper faces of the levers 83. The cross bar 85 has a flange'98 which constitutes a detent and against which the rod 96 bears under these circumstances. Thus when this cranked rod 96 is shifted to the position shown in Figure 3, it will hold the forward ends of the levers depressed and the rear ends raised and thus will hold the abdominal support 55 raised against undue vibration.

The rod which constitutes the pintle 67 for the levers 67 is supported at its middle against accidental depression by a support 99 which is attached to the end face of the angle iron and comes down and extends under the pintle 67, as illustrated in Figure 3. 7 It will be seen that with this construction the cushion 2e constitutes a support for the head. The cushion 36 constitutes a support for the breast, the cushions 2st being spaced apart so as to accommodate the nose of the patient. It will be seen that the head rest may be supported atany desired angle and held in this adjusted position. The breast support may be held against depression by means of the crank rod 4% or this crank rod may be released and the breast support may then'be depressed under thrust against the action of the springs 42. Thus the breast support and the main abdominal support may be depressed together if desired or the abdominal support may be depressed while the breast support remains stationary. The main abdominal support is held always in a horizontal position under downward thrust.

If it be desired to prevent this abdominal support from depressing, it is locked by means of the crank 91. The spring 7 7 may be adjusted to any required degree of tension so as to yieldingly resist the depression of the main abdominal support. The auxiliary abdominal support formed of the sections 84 and 88 may be depressed with the levers 67 or may be held from any depression Q and the section or leaf 88 may be depressed independently of the leaf or section 84 by able so as to give a full support for the feetat any desired angle.

it will be seen that the head rest or head cushion may be raised or lowered and at the same time may be shifted toward or from each other. The abdominal pad or cushion is held level as it goes down during the thrust and there is resilient means for hold ing the abdominal support raised and yieldingly resisting its downward movement and also means whereby the abdominal frame may be locked rigidly. There is also means whereby the breast pad can be held in a rigid position or moved down against the tension of the spring and under thrust.

cushions 55 is supported by two sections Sat and 88 which can be released to permit the two sections to move downward independently of each other.

In Figures 6 to 12, We have illustrated another form of our table which is collapsible or foldable so that it may be readily folded into compact form, as illustrated in Figures 9, 10, 11 and 12, for transportation. The

table shown in Figures 6 to 10 has the same.

general. elements as are present in the table illustrated in Figures 1 to 5.; There is a head section A, a breast section B, a primary. abdominal section C, a secondary abdominal section D, a section E for the support of the thighs, and asection F constituting a foreleg supporting section. The head supporting cushion is pivotally adjustable, as is the breast supporting section B, the abdominal support C is depressible against the action of springs or may be locked in a raised po sition against depression, and the secondary abdominal section D may be also locked against depression or may be depressed with the section C.

The framework of the table includes the leg sections 100 and 100 at the head end of The sec-' tional abdominal support formed by thetee-e29 the table and the leg sections 101 and 101 at the foot end of the table. The leg sections 100 and the leg sections 101% are pivoted to the leg sections 100 and 101 respectively by rivets, bolts or like devices. 1.02 so that the sections 100 will fold up within the sections 100, these sections 100 and 100 and 101 and 101 being of channel iron. The head section also has the depending angle iron legs 103 which are as long asthe leg sections 100, and the leg supporting sections E and F of the table have depending legs 104 which are approximately as long as the sections 103. These also are made of angle iron. The legs 103 are joined by atrans verse bar 105 and the legs 10.4 are'connecteu by a transverse bar 106, while the legs 101 sections.

are connected by a transverse bar 107. Beams formed of sections 108, 109 and 11.0 are disposed, when'the table is set up, on each side of the table, one end of the section 110 being operativelyconnected to the rivet 102 of the legs at the head end of the table and the section 108 at the foot end of the table being connected to the rivet 102 for the leg supporting the foot end of the table. These sections 108, 109 and 110 are formed of channel iron and are pivoted to, each other by the rivets 111. The sections are successively smaller in size so that the section 110 may be turned intouthe section 109 and this section in turn folded into the section 108. The upper flanges of these channel iron sections 108, 109 and 110 are formed with slots 112 to receive the reduced extremities of legs 103 and 104. The upper flange ofeach channel iron sectionllOv is longitndinally slitted, as at 113, andriveted t'o the I inner faces of these sections 110 is a clip 114 which has an outwardly projecting flange 115 at its upper end, this flange extending downward at its outer edge, as at 116, so as to form a hook to engage behind the bolt 102 and interlock therewith. The foot end of the section 108 is made in the same manner for engagement with the bolt or rivet 10 2 of the legs 101 and 101?. a

Thus it will be seen that these longitudinal sections are interlocked with the end legs and that the medial legs 103 and 104 have interlocking engagement. with these Thus the sections are prevented from any fiexure when they are interlocked and brace. the legs 100 and 102 firmly so as to prevent these legs from folding. The legs 100 and 103 are pivoted by pivots 117 which pass through the vertical flanges of theangle iron frame members 118. These members 118 are riveted to a transverse member 119, these members 118 and 119 being angular in cross section. Ears 120 are attached to the members 119 and between these 'earsand the members '118- the upper ends of the .legs 1 00 are pivoted. The upper ends of the legs 103 are pivoted, to the downwardly flange of the member 118. Theselegs 103, as before, remarked, are of angle iron. Attached to the transverse cross bar 121, is a transverse rod 127 and the boards 123 which support the cushions 124 are mounted upon the ears 122. The opposite ends of the boards are braced by a transverse cross piece 125 having downwardly depending ,ears126, (see Figure 15) to which are pivoted spring detents' 127 which extend down within the channel iron. legs 10.0 and engage slots 128 formed in the front walls of the legs 100. These detents are forced into engagement with the front wall by any suitable means. and we have providedme'ans for forcingthese detents out of engagement comprising a transverse rod 129 mounted'in the legs 100 having members engaging the spring detents and having finger pieces 130 on the fronts of the legs. By forcing these finger pieces inward, the spring members 119 are forced nel-shaped supportingirons 135." These in turn are pivoted upon a transverse rod 136,

the lower ends of these irons being connected by a transverse bar 137. This construction permits the section B to, be folded down into parallelism'with the members 135.

For the purpose of holding the'section B at right angles to the bars 135,,we, provide the foldable members formed of the two sections 138 and 139, these members being piv oted atv their ends to the "members 133 and V 135 respectivelyand beingpivoted to each other at 140. When these sections. are

turned intov approximate alignment, thepivot 140 passes inward beyond a lineColinecting the outer ends of the sections and time these sections cannot fold backward unless the sections are pulled outward and then allowed to fold. NVhen the' table is in use,

'these brace sections138 and 139 will be as shown in Figures 6 and 7 "A spring 141 is operatively connected at its lower end to the cross piece 105 and at its upper end is connected to thecross piece 137 so that the breast section Bis resiliently urged upward. A chain 142 limitsthe upward movement of the breast section under the action of this spring, this chain'be ing. connected to the breast section and to the cross piece 105, respectively. It will thus be seen that a depression of thebreast cushion 131 is resisted by; the spring 141; In order to lockthe breast section its raised position andprevent-any depression it at I all under thrust or strain, we provide the cranked rod 143, the middle portion of whichis cranked, as before remarked, this crank rod or shaft passing through suitable bearings 144 on the supports 118 and being provided with a handle 145 whereby it may be operated. XVhen this crank rod is turned to the position shown in Figure 7, the section B cannot be depressed. The legs 101 and 104 are connected by longitudinal angle irons or beams 146 triangular in cross section and the ends of these beams are connected to each other by means of transverse angle irons 1.47.

Mounted upon these longitudinal members '146 and extending transversely across the table is a supporting board or equivalent member 148 upon Which the thigh supporting cushion 149 is supported, this cushion extending slightly beyond this board, as at 150, to provide a slightly yielding portion. Forward of this cushion 149 there is disposed the cushion 151 for the forelegs and foot which rests upon a supporting board 152 to which is attached the angle iron longitudinally extending clips 158 which are pivoted at their rear ends to the frame bars 146, as at 154. Thus this cushion and its support may be raised or lowered. The supporting member 152 has attached to it the downwardly extending lugs 155, to which are pivoted thelocking members 156, the lower ends of; which are outwardly turned and adapted to engage in slots 157 formed in the legs 101. These locking members are adapted to be shifted outward by means of a transverse rod 158 having the handles 159. In other worts this construction is precisely the same as that for shifting out the locking pawls or members for the cushion 124 and its support. Thus the cushion F may be elevated to an angle or dev pressed to a horizontal position as desired.

Disposed between the cushions 149 and the breast cushion 131 is the primary abdominal pad or cushion 160 and the secondary abdominal pad or cushion 161. The primary pad is mounted upon a board or other support 162, which in turn rests upon the ends of sectional levers pivoted at 163 on brackets 164 depending from the frame bars 146. Each lever consists of a relatively long section 165 which is slightly angularly bent at its rear end, a short section 166, and slightly longer section 167. The section 167 is pivotedto the section 166 and this in turn is pivoted to the section 165. Thus the section 166 may be folded into the section 165 and the section 167 ,may be folded into the sections 166 and 165, permitting all these parts to be folded up. It will be understood, of course, that the jointsbetween the sections is such that each of the sections may fold upward but cannot fold downward beg yond a positlonof approximate alignment.

The forward ends of the sections 165 of the levers are connected by a transverse bar 168 and the rear ends of the levers are connected by a transverse bar 169, to which a plurality .of coiled springs 170 are attached. These springs at their lower ends are connected to a transverse'rod 171 whose ends are cranked, as at 172, and extend through the leg sections 104. This crank bar is pro.- Vided with a handle 173. A yoke 174 is mounted upon the cross bar 107 and has a transverse pin 175, and connected to the rod 171 is a detent 176 formed with a series of ratchetnotches 177 adapted to engage with this pin 17 5. Obviously when the handle is turned down this ratchet toothed rod 17 6 will slip down through the yoke and engage with the pin. 17 5 and thus hold the springs 170 under tension. By pulling upward on the member 176, the member 176 will move upward until it again catches. Thus the tension of. these springs 170 may be adjusted and, of course, the greater the tension of the springs, the greater will be the resistance offered to the downward movement of the free ends of the levers formed of the sections 165, 166 and 167 and the greater resistance will be offered to the downward movement of the cushion or pad 160 under thrust.

The secondary abdominal pad or cushion 161 is mounted upon the'support-ing boards or equivalent members 178 and 179. The board 178 is mounted upon channel irons 180 whose forward ends are pivoted between the flanges of channel irons 181 which extend forward and arepivoted to a pintlc 182 from which the hangers 164 depend. VVhilethe channel iron section 180 may be tilted upward into angular relation to the channel iron section 181, it cannot turn downward beyond a point in alignment with this section. The board 179 is mounted upon a channel iron section 183,which is pivoted to the channel iron section 180, as at 184. This section may turn upward but cannot turn downward beyond a positionof alignment with the sections 180. The sections 181 have extending across them the pins 185, and mounted in the frames 146 and extend-- ing transversely thereof is the rock shaft or rod 186 which is provided with hooks 187 engageable with these pins when the rod is turned in one direction but disengageable from' these pins when the rod or shaft is oscillated in the other direction. The rod or shaft 186 is provided with a handle 188 whereby it may be operated.

Under normal circumstances the secondary abdominal pad and its levers rests upon the levers formed by the sections 165, 166

and 167 and is depressed with these sections,

or in other words is depressed with the? primary abdominal pad160. If it be desired,

however, the shaft 186 may be oscillated so wi er faces of the sections 165 and hold thesesections up and against any depression. Ob viously when this cranked shaft 189 1s turned with its cranked portion downward,

then a depression of the abdominal cushion or pad 160 against the action of the springs 170 will be secured.

In order to prevent any rearward movement of the levers 165 due to any swinging of the hangers 164, braces 190 are mounted upon the uprights 104 and extend rearward therefrom and the pivots 163 for the levers 165 extend through these braces.

It will be seen that with this construction the head rest 124 may be raised to any de sired angle. The breast support 131 may be supported against downward movement or may be permitted to have downward movement against the action of the spring 141. The main abdominal support 160 may be depressed against the action of the sprlngs 170 or may be held against depression and the secondary abdominal support 161 may move downward with the main abdominal support or be held against depression, though the main abdominal support is depressible. Preferably the secondary abdominal support 161 is formed with a medially depressed portion extendmg longitudinally of the pad or cushion 16 1- with a central opening 191. I do not wish to'be limited to this, however.

The particular object of the construction illustrated in Figures 6 to 12 is to provide a chiropractic table of the same character as that shown in Figures 1 to 5 but which 18 foldable into a small compass so that 1t may be readily transported from place to place, set up and knocked down. In dlsassembling the table, the side rails or beams formed of the sections 108, 109 and 110 are first re-. moved from engagement with the legs 100 and 102. The section 110 is then folded within the section 109 and this in turn folded within the section 108. This leaves the head section and what may be termed the body section of the table separate from each other. The leg sections 100 are then folded within the sections 100. The head rest 124 should be previously folded downward against the supporting frame. The braces 138 and 139 may then be collapsed and the spring 141 disconnected. When the braces are collapsed, the cushion 124 with its support 123 is turned inward onto the cross bar of the front legs. The front legs are then turned inward and the legs 103 are then turned inward and fit over the front legs. The parts are then in the position shown in Figures 10 and 12 and the head and breast pads are folded into a flatconr pact package easily transportable and eas ily handled. In folding the body of the table, the legs 104 are first folded into parallel relation to the-members14-6 with the cross bar 106 brought tightly down against the levers 165 and then the legs 102 are folded up into the legs 101 and then the legs 102 are folded up tightly against the levers 165. The parts are then in the position shown in Figures 8 and J9.

hen this has been done, the extension irons 180 of the secondary abdominal support161 may be turned upward at right angles 'to' the irons 181 and then the outer section of the abdominal support may be turned over, as shown in Figure 10. The iron-s 166 are then turned upward at right angles to the. frame 146 and the irons 167 turned over into parallel relation to the frame 166. The folded beams 108,109 and 110 may then be disposed on the side margins of the cushions 149 and 151 and the head rest disposed against the cushions and between-these folded beams. The parts are then in the position shown 'in Figure 13 and may be readily packed in a suit case and transported. I

While we have illustrated certain details of construction and arrangements of parts which we have found particularly effective for the purpose intended, we do not wish to be limited to these details or the exact arrangement of the parts, as these may be-varied in many details without departing from 1 the spirit ofthe invention. Neither do we wish to be limited to the materal to be used in the construction of this table, as while we have lllustrated the table as formed ofangle Irons and preferably constructed that way, yet it is obvious that the parts of the table may be made of wood or of other material.

We claim 1. A chiropractic. table having a supporting frame, a head support and a breast support .piv-otally mounted upon the frame adacent one end of the head support, the breast support having downwardly extending arms, a spring operatively connected to the arms and resisting depression of the breast support, a cranked shaft mounted upon said frame and extending parallel to means for locking the secondary support from depression. v

8. A chiropractic table having a supporting frame, a main abdominal support, a lever mounted upon said frame, the main abdominal support being mounted upon one end of said lever, a spring engaging the opposite end of the lever from the support and resisting depression of the support and of the adjacent end of the lever, means for adjustably tensioning said spring including a cranked shaft to which the lower end of the spring is operatively connected, a handle connected to the shaft for oscillating it, and means for latching the handle in any adjusted position.

4. Ina chiropractic table, a supporting frame, a main depressible abdominal support, a lever pivoted intermediate its ends and connected at one end to the main abdominal support, a spring connected to the opposite end of the lever and yieldingly resisting depression of the main abdominal support, a secondary dep-ressible abdominal 3 support, a lever upon-which it is mounted, the

pivot of the lever being coincident with the pivot of the lever of the main abdominal support and the secondary abdominal support overlying the lever of the main abdominal support, means for locking the main abdominal support raised and against depression, and independent means for locking the secondary abdominal support raised and against depression.

5. A chiropractic table having a support ing frame having a foreleg support, a thigh support, a main abdominal support and a secondary abdominal support disposed between the thigh support and the main abdominal support, the abdominal sup-ports being depressible, means yieldingly resisting the depression of the abdominal supports, and independent means for locking either of the abdominal supports in a raised posi tion, the secondary abdominal support being formed in two sections flexibly connected to each other.

In testimony whereof we hereunto affix our signatures. I I
