This invention relates to a novel method of adjusting the vertebrae of the spine by providing a table having means whereby the body of the patient may be turned simultaneously with the adjusting move to the vertebrae.

While a number of adjusting tables have been devised with table top sections that are movable in a variety of positions, the object of this invention is to construct an adjusting table, where the table top is divided into a number of sections having a lateral turning movement in an arc of a circle, the center of which is above the top of the tab-1e, the object of these laterally turning sections being to turn the body of the patient at the moment the adjusting move is made to the vertebrae, said table sections having means whereby they may be turned simultaneously with the adjusting move to the vertebrae for the purpose of facilitating moving these in position.

Another object of my invention is to provide means whereby the various table top sections may be locked in a horizontal position so as to permit using the table as an ordinary adjusting table and facilitate getting on and off the table by patient.

Another object of my invention is the construction of the top surface of the main body supporting table sections, which are made concave from side to side to correspond with the convexity across front of body of the patient, so as to better support this on the table.

Another object of my invention is to construct the part of the table supporting the legs of the patient lower than the body supporting part of the table for the purpose of facilitating getting on. and ofi the table by the patient.

A further object of my invention is to provide means on the table whereby the turning of the sections of the table may be operated by the foot or knee of the practitioner.

Still further objects and advantages will appear in the following description in connection with the accompanying drawings in which:

Fig. 10 is a cross section of part of the mechanism for locking the main body supporting sections in position taken on the line lit-I9 of Fig. 5.

Fig. 11 is a side elevation of a modification of table.

Referring now more particularly to the drawings in which similar reference characters indicate similar parts 29 designates the rear legs of rear part of the table, these being fastened to the longitudinal side bars 2!, which at their front ends are supported by the legs 22. The side bars 2| are connected together by cross pieces 23, Fig. 6, these having their upper sides formed concave in an arc of a circle.

'The rear body support of the table comprises a lower horizontal part composed of the side members 24 united by the cross board '25, and an upward and forward inclined part composed of the side members 26 united by the cross board 21, the

cross boards

25 and 21 being covered by suitable cushions 28 and give support to the legs and lower body of a patient. Fastened to under surfaces of side members 24 and cross board 25 are the cross pieces 29, these being placed directly above the cross pieces 23, Fig. 6, and are curved convexly in an arc of a circle at their under sides to correspond with'the concave upper sides of the cross pieces 23 so as to permit rear part of the table to turn in a side direction on its supporting frame. Attached to outer and under sides of the cross pieces 29 in any suitable manner as by countersunk screws and curved to conform with the curve of the cross pieces 29 are the arcuate track members 39, which extend slightly below the curved under sides of the cross pieces 29 and rest on the track supports 3|, which may be flat metal strips attached to the side bars 2| and serving to reduce friction when turning rear table support, this being held in turning engagement with its frame I Connected to the front part of the side bars 2| in any suitable manner as by bolts are the two cross pieces 33, and to upper sides of these are attached in a similar manner the middle longitudinal bar 34 and the two outer longitudinal bars 35, the outer bars at their forward ends being attached to and supported by the legs 35. Hingedly connected to upper and rear part of the bars 35 is the swinging stop member 3?, which may be turned inward against bottom of cross board 2'! until at right angle with this, it being stopped from swinging past this position by the cross piece 38 and serves in this position to lock the rear support from turning, and when turned forward it permits rear table section to be turned to either side.

The side bars 35 give attachment to a series of upwardly extending supports 39, these being connected together by cross pieces 49, Fig. 5, the upper sides of which are concave and give support to the body supporting sections 4 I, these being formed in an arc of a circle at their under side and are preferably made concave at their upper side. The middle part of under side of sections 4| is grooved 42 and to their outer and lower sides are attached the arcute track members 43 curved to conform with the downward curve of under side of sections 4| and extending slightly below the under side of these; the arcuate track members 43 resting on track supports 44 attached to upper sides of supports 39 for the purpose of reducing friction in turning of sections 4!, these being guided and held in position on the supports 39 by means of guide members 45 attached to the cross pieces 40 and having a projection extending inward over the arcuate track members 43 for the purpose of keeping the sections 4| in position on their supports.

The sections 4| may be locked in horizontal position, so they can not turn, by means of a pair of stop members 46 hingedly connected at their lower ends to blocks 41 Fig. 5 attached to outer sides of supports 39 and with their upper ends engaging the grooves 42 at under sides of sections 4!, and for the purpose of assisting in moving the stop members 46 out of and into engagement with the sections M, the stop members may be provided with knobs 48 and are held in their upward position by means of a pair of flat springs 49 curved inward at their upper end and connected to the blocks 4! at their lower end.

The top sections 4| are provided with suitable cushions 50, and to front side of front section 5! is attached a downward extending board 52, which gives attachment to a U shaped forward extension 53 Fig. 4 provided with a cushion 54 and serving to support the arms and shoulders of the patient when in position on the table.

The various table top sections may be turned individually or may be connected together by any suitable means as by a sliding bolt 55 attached to outer sides of the body supporting table top sections and adapted to engage a corresponding opening 56 in its adjoining section.

For the purpose of more'effectively turning the body of the patient, straps 5'! may be provided, these straps being fastened at one end to outer sides of the various table top sections, and when placed over the patients back they may be fastened together by any suitable means as a buckle and serve to hold the patient in more firm contact with the table top sections, so as to make the turning of the patients back more closely follow the turning of the sections.

The middle longitudinal bar 34 is carried forward beyond the two outer bars 35 and rests on the cross pieces 58 Fig. 3 attached to the upright supports 59. At their upper ends the upright supports have attached the cross pieces 5E, these being concave at their upper sides to correspond with the convexity of the cross sections 5!, which at their upper sides are united by the cross board 62 with the brace 53 and have on their under sides at the outer edges attached the arcuate track members 64, which slide on friction reducing track supports 65 attached to upper side of supports 59. Guide members 66 are connected to outer sides of cross pieces and have a pro jection extending over upper surface of arcuate track members 64 for the purpose of guiding and holding the cross sections 6| in position when turning these. The board 62 is provided with suitable cushions 61, which give support or the head of patient, and in order to lock the head support in position when desired, a lock member 68 is provided, this being at its lower end hingedly connected to front side of front cross board and when turned upward engages a curved, fiat spring catch 69 attached to the front section 5|, it being locked in position by means of the side stops 10, also attached to section 6!.

The various body supporting sections may be turned in any manner convenient, as by the hand, knee or foot of the practitioner, however in the drawings I have illustrated the generally preferred form of turning these by foot operated means.

To the lower part of the supportnig legs of the table are hingedly connected the foot boards H, which near their outer ends in any suitable manner as by screw eyes or hooks '12 give attachment to a flexible cord 13 of suitable material as wire, which at its other end 14 is connected in a similar manner to upper part of the table top sections; the cords may be connected at their upper ends to the side of these sections on the opposite side of their foot board attachment. The foot boards may be provided with a plurality of hooks or eyes for attachment of lower ends of cords 13, whereby the degree of turning of the table top sections may be varied to suit the need of various patients. To the top of foot board may be attached any suitable material as rubber for giving the foot of the practitioner a better grip on the foot board and prevent slipping, and also the under side of the foot board may have attached a shock absorber 15 of flexible material as felt or rubber to avoid noise or jar when pressing foot board against floor.

The main body supporting sections may be covered by an extra cushion 16 over the individual cushions of each section.

Fig. 7 illustrates a modified body supporting section adapted to be turned by the knee of practitioner, it being provided with a knee operated suitably cushioned extension 11.

Fig. 11 illustrates the adjusting table with a modified form of mechanism for turning the body supporting sections of the table, which mechanism includes a foot operated board I8 on each side of the table and extending between supporting

legs

22 and 36 of table, hingedly connected at their inner edge to said legs. At their upper and outer part the foot boards 18 give attachment to connection means as cables or rods 19, which at their upper ends are attached to the outer ends of the body supporting sections and serve to turn these when the foot board is moved downward, and in order to control the movement of the various body supporting sections independently of each other the cables 19 are made detachable and may be disconnected either at their upper or lower ends by means of eyes or hooks engaging corresponding hooks or eyes on foot boards or table sections, and each table top section being provided with individual turning means, the sliding bolts 55 illustrated in Fig. l are dispensed with in this modification of table.

The enclosed drawings illustrate a table with a frame constructed mainly of wood, however any other suitable material as metal may be used, and also the part of the table supporting the main body of the patient may be divided into a greater number of sections than the 3 sections illustrated in Figs. 1, 2 and 11.
