To all fw kom t may concern:

Be it known that I, ADRIAN D. NICHOLS, a citizen of the United States, and a resident of the city of St. Louis and State of Missouri, have invented a new. and useful Machine for Correcting the Maladjustment of the Atlas and Axis, therst two spinal vertebrae of the neck, of which the following is a specification.

The object of the invention lis to increase the supply of blood to the brain and spinal cord through the vertebral artery, which is diminished in case the atlas and axis are not in correct alinement. Incorrect alinement, or maleadjustment, of the atlas and axis also affects the circulation through the internal carotid artery.

rlhis invention relates particularly toa mechanical device for correcting the maladjustment of the atlas and axis, and for securely holding these two vertebrae (atlas and axis) by permitting a nodding motion of the head of the patient, so as to correctly adjust the atlas and axis to their normal ren lation with the skull and spine.

Further details ofthis invention appear below in connection with the description of the device illustrated in the accompanying drawings for carrying out the theory, and what the invention consists in is more Vparticularly defined'in the appended claims.

In the drawings, where the same reference characters are used to designate like parts in the several views,

Figure 1 is a front view of a suitable device or apparatus for performing the invention;

Fig. 2 is a side view, and Fig. 3 is a plan view of the same, the head strap being removed in Fig. 3;

Fig. a is a side view, and Fig. 5 is an end view of an adjustable bracket and finger,`

forming part of the device; and

Fig. 6 is a cross-section of a portion of the adjusting mechanism for each pair of brackets.

The apparatus is mounted on a portable frame 10 which may be placed against the end of a suitable support or table, and secured thereto by hooks or clamps. The portable frame 10 has a shelf 11 extending across its front, upon which is mounted suitable apparatus for securely holding the bones of the neck and head. This apparatus comprises a vertical slide 12, which is adjustable up and down by means of a vertical screw operated by a hand wheel 13. Upon the vertical slide 12 is slidably arranged a cross slide 14k, which is adjustable toward and away from the table by means of a horizontal screw, operated by a crank han-` dle 15.

The cross slide 14 supports two sets of clamping fingers for engaging the vertebrae of the neck. The forward set 16 of clamping fingers is adapted to engage over or around or any other way necessary to hold iirmly the lateral processes of the atlas (which is the rst vertebra of the spinal column) upon which the skull pivots and is supported. A second set 17 of fingers engage over or around or any other way necessary to hold firmly the lateral processes of the axis, which is the second vertebra of the spinal column.

Differently shaped fingers may be used to conform with the shape and arrangement of the vertebrae of the patient, and the ends of the lingers may be covered with pads or rubber, or other suitable material.

The head rest 18 is pivotally mounted on arms 19. The head rest has an adjustable pad 20, upon which the back of the head of the patient rests, also an adjustable clamp` ing plate 2l for engaging the top of the head to position it centrally in the frame. An adjust-able strap 22 with its ends cngaging slots in the sides of the frame, is

adapted to be drawn tightly over the top of the head orV forehead. These three cla1np ing means hold the head securely in place in the frame. The pad 2() and plate 21 are mounted by means of ball and socket, or double universal joints, upon the ends of the adjusting screws 23, so as to be free to accommodate themselves to the shape of the head.

The supporting pad 20 and strap 22 are adjustable horizontally toward and away from the fingers 16. The supporting screw for the pad 20 is mounted in a sleeve 24, which can be moved along a slot in the depending arm 25 of the frame, in which it is mounted, and can be clamped in any desired position of adjustment by means of the knurled nut 26. The head rest is supported in its normal horizontal position by means of a pivoted arm 27 which engages under the extremity of the arm 25. rIhe pivoted arm 27 can be swung out of the way when it is desired` to oscillate the head-rest. The head rest has a handle 2S for oscillating it up and down.

The forward set of fingers' 16 which engage the atlas are removably held in adjustable blocks 29, which are slidably mounted in a pair of brackets 30, which, in turn, are slidable toward and away from each other in guides in the cross slide 14. The blocks 2f) which hold the fingers, are individually adjustable by means of adjusting screws 31, which are attached to them and threaded in the upper ends of the brackets 30.

The brackets are adjustable simultaneously by means of a right and left screw 32 horizontally held in the cross slide 14. The oppositely threaded ends of the screw 32 engage in threaded holes through the lower ends of the brackets 30. The second set of fingers 17 are held by blocks 33, which are adjustably mounted in the slide boxes 34 for horizontal adjustment toward and away from each other and for adjustment toward and away from the fingers 16.

The slide boxes 34 are mounted on the brackets 35 and are adjustable forward or backward by means of knnrled screws 36. The brackets 35 are adjustable simultaneously toward and from each other by means of a right and left hand screw 37, which engages in threaded holes in their lower ends. The right and left screws and 37 maj7 be turned separately or simultaneously by means of the foot pedals 39 and 40 in order to leave the hands free for manipulating the clamping fingers and adjusting other portions of the apparatus.

Each of the right and left screws 32 and 37 has a spool 41 rotarily mounted upon its end next the knnrled disk 88. rIhe adjacent face of the spool is ypro-vided with ratchet teeth and adapted to be engaged by a springpressed detent 42. The spring-pressed detent 42 can be turned to engage the ratchet face of the spool 41 to slide over the teeth in either direction, or it can be held out of engagement with the teeth.

Each spool 41 has a cord 43 wound upon it, the lower ends of the cords 43 being connected to the pedals 39 and 4f), respectively, so that by oscillating the foot pedals up and down, the spools 41 can be caused to oscillate around the right and left hand screw shafts 32 and 37 respectively. The small spiral springs 44 are arranged in annular recesses in the spools 41, one end of each spring being connected to the spool and the other end being connected to a fixed part ofl the cross slide 14. These spiral springs are under sufficient tension to keep the cords .43 taut and canse the spools to oscillate with the foot pedal. Byoscillating the foot pedal 39 and setting the detent 42 in the proper position, the screw shaft can be rotated in either direction desired to adjust the brackets 30 toward or away from each other; and the shaft 37 can be rotated in like manner by means of the foot pedal 40 to adjust the brackets 85.

In operating this invention or device, the patient reclines on a suitable support or table, with his shoulders resting squarely upon its end, adjacent to the portable frame 10, and his head resting on the pad 20 of the head rest. The pad 20, plate 211 and strap 22 of the slide rests are adjusted to hold the patients head securely in position for the mechanical fingers to grasp or firmly hold the transverse processes of the patients atlas and axis.

. The front set 16 of fingers which holds the atlas, and the rear set 17 which holds the axis, are adjusted toward each other simultaneously by means of the foot pedal, the operator using his fingers to guide them into proper position and making \\f'haterer slight individual adjustments of the fingers may be required to suit the vertebra of the patient. The sets of fingers may be operated by hand by turning the knurled disks.

After adjusting the fingers to clamp the vertebrae securely, the operator turns the pivot arm 27 out of the way and slowly oscillates the head rest 1S up and down h v means of the handle 2S. The motion o l the head is maintained for sufficient length of time, depending upon the peculiarity ot each individual case, and occasionally the fingers 16 and 17 are adjusted by the operator to bring the vertebrae gradually into proper alinement.

In some cases the motion of the head is unnecessary, it being sufficient to hohl the head and body while the fingers 16 and 17 are moved vertically and horizontally to adjust the atlas and axis.

The invention is not restricted to the Aform of apparatus shown and described.
