the-feet of the person are somewhat higher than the head. Legs I l or l2 or both may be provided with means is for adjustment in length in any well-known manner if desired. Table it is provided with a central cut-out portion M and a cut-out portion Ma and a pair'of brackets which provide pivot supports for a pair of rockarms 16 positioned on either side of the table. Other equivalent adjusting and locking means may be provided if desired. A plurality of rollers 2| are mounted between bearing blocks 18, it being understood that rollers 2! may be of any suitable construction, such as soft or hard rubber, sponge rubber or plastic or the equivalent.

As stated herein above the person to be treated may lie on the table, and the adjustment of oily and dtioning of the patient on the table.
pro ded with" a crank vpin it -which engages" a a}; dfiild in; submit portions [4 and Ma blocks I9 in slots I! will provide a varying degree.
In the Figs. 3 to 6 I show modified features of the invention. In these figures the rollers and 30a are mounted in brackets which are slidable vertically so as to be dropped below the top of the table, the brackets being provided with looking screws 46 which hold the brackets in upper position when so operated. Rollers 80 are mounted in a curved track 4'! which moves the rollers in a curved path such as to follow the small of the back, and thus to produce a maximum effect without injury to the patient.
In Fig. 6 I show further modified features which comprises a frame 48 which is adapted to be placed in a longitudinal recess 49 in the top of the table frame 48 having a tubular passage for connection to a vacuum tube 50 which is connected to a vacuum pump 5| suitably driven by motor 22. A plurality of shallow vacuum cups 52 are connected to frame 48, cups 52 being of progressively smaller diameter toward the head end of the table, the arrangement being such that thecups 52 lie under and along the back of the person being treated. A tube 53 is suitably connected to vacuum line 50 and has an open end 53 which can be intermittently closed with a finger to provide a fluctuating vacuum effect at the cups 52 which intermittent or pulsating vacuum effect is most desirable for satisfactory actuation of the invention.
In Fig. 7 I show a modified or substituted form of roller mounting. In this figure a plurality of rollers are provided with ball end shafts 61 which are carried in bearing blocks l8a for pivotal mounting in trunnion blocks lea adapted to be secured at the slotted ends I! of rock arms [5, rollers 21 and bearing'blocks 18 being removed and replaced by rollers 60 and bearing blocks 18a when the rollers of the form of Fig. 7 are to be used on the table. A pair of bracket pieces 62 pivotally connected together at 63 provide mounting for the inner ends of the shafts of rollers 50, anda clamp screw 54 provided with an adjusting nut 65 is secured to the ends of pieces 52 by which said'pieces may be drawn together and change the angular relation of rollers 60. A
spring 66 is mounted on bolt 54 and serves to separate pieces 62 and raise the inner ends of rollers 52 so that the rollers have a variable angular relation to provide rolling contact to conform somewhat to the figure of the person to betreated. I provide a hood or cover 43a over rollers 00 and similar to hood 43.
Table I0 is provided with a pair of arm rests 55, formed substantially as shown and preferably of resilient material or padded, the rests being mounted on members 56 as secured to adjustably positioned blocks 51 slidably mounted in slots 58 in table 10 and secured in adjusted positions by a screw type or plunger holding pin 59. Arm rests 55 serve to render the person to be treated in a more comfortable position when on the table.
Having thus described my invention, what I claim and desire to secure by Letters Patent is:
1. In a posture system, a table for the support of a person to be treated thereon and having apertures therein, a plurality of transverse rollers in said apertures, a plurality of transverse rollers spaced above said table, said rollers being mounted to be longitudinally reciprocable relative to the length of the table, and means to reciprocate said rollers, said last named rollers being moved forwardly when said first named rollers are moved ba-ckwardly and vice versa, said means including a pair of rock arms for supporting said last named rollers.
2. In a posture system, a table for the support of a person to be treated thereon and having apertures therein, a plurality of transverse rollers in said apertures, a plurality of transverse rollers spaced above said table, said rollers being mounted to be longitudinally reciprocable relative to the length of the table, and means to reciprocate said rollers, said last named rollers being moved forwardly when said first named rollers are moved backwardly and vice versa, said means including a pair of rock arms for supporting said last named rollers and engageable with the supports of said first named rollers.
23. In a posture system, a table for the support of a person to be treated thereon and having apertures therein, a plurality of transverse rollers in said apertures, a plurality of transverse rollers spaced above said table, said rollers being mounted to be longitudinally reciprocable relative to the length of the table and a plurality of vertically movable rollers adapted to engage the feet.
4. In a posture system, a table for the support of a person to be treated thereon and having apertures therein, a plurality of transverse rollers in said apertures, a plurality of transverse rollers spaced above said table, said rollers being mounted to be longitudinally reciproc able relative to the length of the table and a plurality of horizontally and vertically movable'rollers adapted to engage the feet.
