'- A pplication filed February 2a, 1915. Serial No. 9,790.

To all whom it may concern:

Be it known that I, ALVA E. GREGOBY, a

citizen of the United States, residing at' Oklahoma, in the county of Oklahoma and State of Oklahoma, have invented certain new and useful Improvements in Adjustment-Tables, of which the following is a specification, reference being had to the accompanying drawings.

This invention pertains to apparatusused by chiropractors, osteopaths, and physicians in the treatment or adjustment of patient's.

An object of the invention is to provlde improved means for supporting the patient without subjecting him to'unnecessary pain or discomfort, and at the same time in such manner that his body and limbs may be treated oradjusted in the easiest and most convenient way. 1

Another object is to overcome the settling ofthespine of the patient and the consequent thinning of the 'intervertebral diskfs which comes on with age, and to overcome any contraction of the spinal musculature from direct spinal injury or reflex contraction due to peripheral in uries'or irritations.

Other objects and advantages of the in-' vention will beset forth in the ensuing description.

The accompanying drawings show one embodiment of the invention in practical form.

vertical plane, looking laterally of the'apparatus; the left-hand end of the figure being taken as the front end for convenience of this description.

Fig. 2 is a side elevation in the same direction as Fig. 1, but showing the patient turned face downward'and parts of the apparatus shifted in position.

Fig. 3 is a perspective view showing certain appliances for hitching to the patients head and shoulders.

Fig. 4 is a perspective view of a certain slidable frame and associated parts at the rear end of the apparatus' Referring to the several figures, in all of Figure 1 is a sectional view taken on a which like characters of reference designate which rests upon and is secured to said girts; I

theliop being comfortably upholstered as at A second table 17 is mounted upon the opposite or front end of the base 5, but with its legs 18 movable lengthwise on said base, the top 19 of this table also being comfortably upholstered as at 20.

For the comfort of patients with pro truding abdomen when lying face downward in the position shown in Fig. 2, the legs 18 of the second or front table 17 at the end adjacent the table' 11 rest upon a stepped block 21 which is fixed to the bottom 9 of the base 5; and by setting said legs on higher or lower steps of said block the top of the table may be tilted to accommodate any form of patient.

- As best shown in Fig, 1, the front table 17 is provided with a suitable clearance 22 for the face-of the patient when lying face downward.

In further arrangement, means are provided for applying tension to the limbs and body of the patient.

In arranging this means, a standard 23 is erected at the front end of the base 5 and made rigid by a brace 24.

A small roller 25 has its shaft 26 journaled in a cast bracket 27 on the upper end of the standard 23, and one end of this shaft is provided with a crank 28.

The roller '25 is provided with a small 30 i ward extremity 49 of the frame 32.

To place the neck and spine under tension, the patient may be placed in the posiably engage a ratchet-wheel 31 formed on one end of the roller 25 to resist an unwindingpull on the cable.

. This cable 29 is adapted to be hitched to one'end of the patients body, preferably to the head and shoulders, by improved means later described.

o In further arrangement, a cast-metal frame 32, shown separately in Fig. 4, is mounted in supporting guidebars 33 on the under side of the top of the fixed table 11 and adaptedto be given movement in the direction of length of the base 5.

For moving this frame 32 and adjusting its position, ashaft 34 is journaled through the table 11 and provided with a gear-pinion 35 which meshes with a toothed rack 36 on said frame, theouter end of this shaft having a crank 37 and a ratchet-wheel 38 7 and passed under the arms.

parts motion through a connecting-rod 47 to a lever 48 which is fulcrumed in a reartion shown in Fig. 1, the head and shoulders being pulled upon by the cable 29 and the lower 'part of the bodyby the lever 48.

In hitching to the head and shoulders, a short lever 50 is fulcrumed to the end of the cable 29; straps 51 being attached to the head of the patient by an improved bridle arrangement later shown, and similar straps 52 attached to the opposite end of said lever In the use of the lever 50, part of the pull of the cable 29 is brought upon the shorulders and part on the neck, the combined pull being sustained by the spine.

Thefulcrum point of the lever 50 may be adjusted to properly divide the pull between the head and shoulders.

In hitching to the lever 48, a suitable harness 53, may embrace the patients limbs or lower part of the body and a suitable cable 54 extended from this harness to the upper end of said lever.

'- By starting the motor 43 and the swinging. movement of the lever 48, a pull of the 60rd upon the patient at regular intervals in opposition to the resistance of the cable 29 has the efl-ect of alternately stretching and relaxing the body and the amount of stretch may be increased by gradually sliding theframe 32 and its lever 48 rearward in the manner aforesaid.

In order to allow the lower portion of the patients body to move freely under the stretching and relaxing action'of the cables #29 and 54, the two tables 11 and 17 may form a rolling support for the hips; said bridge being supported by a pedestal 57 which is footed removably on the bottom 9 of the base 5;

In place of using the lever 48, the ankles may be strapped to a supporting block 58 which is fixed to the rear end of the frame 32, and a constant pull on the limbs and body produced by carefully and gradually forcing said frame rearward in the manner described.

In arranging improved means for hitching the straps 51 of the lever 50 to the head, a small pad 59 is provided for the chin and an elongated pad 60 for the back ofthe neck, these pads being connected together at each side of the head by short straps 61.

At each side of the head, a longer strap 62 attaches to the end of the chin 'pad 59 and to the adjacent end of theneck pad 60,

these straps 62 passing slidably through loops 63 which secure them to their respecvtive straps 51 aforesaid.

The straps 51 are secured to the lever 50 by being firstsecured to the ends of a short lever 64 whose central portionis in turn fulcrumed to said lever 50.

By the improved arrangement of the levers, straps, and other connections described, the pull of the cable 29 is made agreeable to the patient and the pull upon his head and shoulders adjusted to suit the treatment required.

Having thus described the invention, I

1. In apparatus of the class described, a

. the tables in difl'erent angular positions,

for applym g tension to the patients means body, and means whereby the tension is relaxed at intervals.

2. 111 apparatus of the class described, a pa1r of independent tables, and a stepped block arranged under one of the tables for setting the same in different angular positions.

3. In apparatus of the class described, a

positions, and means for applying tension to the bodycof a patient on the tables.

eL In apparatus of the class described, a support, one end of the support carrying an anchorage to which the atients head and shoulders may be hitche said anchora e including a lever fulcmmled intermedlate its ends, means for hitching one end 5 of said lever to the patients head, and means for hitching the other end' to the patients shoulders.

Withess my hand this 13th day of Febmay, 1915.
