Be it known that L. EDWARD BISHOP, a citizen of the lj/ lil lt'l States, and a resident oi. Endicott. in he count-v otBroomev and State of New Yorlnlmve inventeda new and li'i'iproved Chiropractic-Table, of which the following is a full, clear, and exact descri ption.

is made of a table frame a head and chest rest, leg rest and a foot rest or step, the

. said several rests being held lengthwise adjustable on the said table frame. Use is also made of a yielding abdominal rest mounted on a table frame intermediate the leg rest and the head rest. Use is further made of a head rest having two cushions adapted to be moved transversely apart-to provide steps between the cushions for accommodating portions of the face ofthe-patient. i

A practical embodiment of the invention is represented in the accompanying drawin-gs forming a part of this specification, in

which similar characters of reference indi-, cate corresponding parts in all the views:

dicated in Fig. 1. On the table frame D are mounted the head and chest rest F, the abdominal rest G, the leg rest H and the foot or step rest I, the several rests F, G, H and I being lengthwiseadjustable on the table frame D to accommodate persons of different stature. I l s i The table frame D is preferably provided with tubular side beams D provided near the foot end with connected "sleeves I) mounted to swing on the pivot C and adapted to be fastened in place on the side beams D by setscrews D or other means to' perniit oi adjustingthe' table frame D lengthwise relatively to the. pivot C with a view to projectthe foot end of the table frame a: desired. distance beyond the pivot C, as

plainly'indicated in Fig. l. The sleeves D are rigidly connected with each-other by a tubular crosspiece D through which extends the pivot- C. The middle portions of the f side beams D are curved. to locate thehea d portions of the sidesof-itlie table frame in a different plane from the foot portions thereof so that the head portions of the table frame are lower at thetime the table frame" is in horizontal position than the foot portions of the table frame. The foot ends of thesidebeams D. of the table frame I) are connected with each other by a crosspiece D on which is secured one end of a chain J eX-' tending-downwardly and passing arounda guide pulleyJ" journaled in the stand atthe foot of the base A. The chain J then extends forward and connects. with a crosshead- J connected by counterbalancing springs J with a crosshead' J attached to or forming part of the base A. The springs J 3 are sutficiently strong to 1 approximately counterbalanceQthe/table ,frame D with a person of ordinary weight in position on the table. In case the-table is to be used for a patient.

' ofmoreftan i dinary weigl1t,nse is made -c interbalancing spring J thecrosshead J and send-to, a'chain J, at

i es

tached to the peripheral face of a pulle K secured on the lower end of a vertical s aft K journalcd on the base'A. l he upper end of the shaft K is provided with an arm K to allow of turning the shaft K to cause the pulley K and chain J to give more or less tension to the auxiliaryspring J according to the direction in which the arm K is turned. On the arm K -is pivoted a locking pedal K provided with a tooth K adapted to engage a toothed segment K fixed on the base A to lock the arm K in the adj usted position. \Vhen the table frame pedal K into unlocked position, it is ev1- dent that the spring J is normally not placed under tension during the movement ofthe table frame D from inclined to horizontal position. When, however, a patient of more than ordinary weight is to be supported on the table then the operator manipulates the arm K and the pedal K to turn the pulley K with a view to draw the chain J taut and to lock the arm K against movement by the pedal K engaging the toothed segment. When the table frame D is'now swung from inclined position into horizontal position and the crosshead J is thereby moved to the right then not only the springs J: are placed under tension but also the spring J 5 to compensate for the ex- .40

tra heavy load on the table frame D. ,It is understood that by moving the arm K more or less to the right, it is possible to increase or decrease the tension of the spring J to suit existing conditions.

In order to lock the table frame Din horizontal position, the following arrange ment is made, special reference being had to Figs. 1, 7, 9 and 10: On the base A is fixed a keeper L adapted to-be engaged by'a hook L extending from a disk L mounted to turn loosely on a shaft L extending lengthwise of the table frame D. The shaft L is journaled in the leg E and in a bracket L attached to the side beams of the table frame D (see Figs. 1 and 7), and the outer end of the shaft L? is provided with a suitable handle L under the control of the operator for turning the shaft L The arm L is provided with pins L extending. into L-shaped slots L formed in the bracket L and the arm- L is also provided with an opening L through which extends loosely.

the shaft L Into the opening L extends a pin L held on a collar L attached to the shaft L Now when the latter is turned the pin L turns the arm L to engage the hook'L with the;keep er L and during this turning movement of the arm L the pins L move into" the vertical portions of the slots L" thus allowing'the arm Lto yield 4 downwardly. By the arrangement described the table frame is locked against upward swinging motion but is free to yield slightly in a downward direction.

The head rest F is constructed in detail as follows, special reference being had to Figs. 1, 2 and 5: On the side beams D of the table frame D is slidably mounted a carriage F having sleeves F slidably engaging the side bars D and having uprightsF extending from the sleeves and connected with each other by crossbars F to form a rigid structure. On the uprights F are mounted Crossbars N to extend through verticalslots in arms N )ivotally connected at their upper ends at N with lugs N of a table N supporting transversely adjustable cushions O and O, as hereinafter more fullydescribech On the outer ends of the crossbars N are pivoted cam levers N adapted to engage ashers N" slidable on the crossbars N and abutting against the outerfaces of the slotted arms N. The inner faces of the said slotted arms 1* .rest

against washers N held against the qip rights F of the head rest carriage. This the arms N are adj ustably fastened in place on the crossbars Na On swinging the cam levers N upwardly the pressure on the washers N is released to allow of raising,

loweringor inclining the table N and with it its cushions O and O, and when the dc: sired position is reached the cam levers N are swung downward. to exert pressure against the washers N to clamp the side ion arms N firmly in place against the washers N to hold the table N, with its cushions O, O, in the adjusted position. On opposite sides of the carriage are mounted clamping levers F. (see Fig. 1) adapted to engage the side beams Dof the table frame I) to permit of securely locking the carriage F in place after the same has been adjusted lengthwise on the table frame D.

The bottoms 0 O of the cushions O, O

are of wood or other rigid material and are mounted to slide transversely on a dovetail tongue N fixed transversely on the top of the table N. In order to. move the cushions O and 0' toward or from each other, use is made of pins P, P engaging the bottoms O O and extending through transverse slots formed in the table N. The pins P and P are attached to links P P pivot ally connected with each other by a pivot P engaged by a rod P j-1nounted to slide lengthwise inv a suitable bearing P secured to the under side of the table N. V The rod 1 is provided with a suitable handle P under the control of the operator for irrpliso parting a lengthwise movement to the rod P to cause the links P P and their pins P, Pt'o slide the cushions O and .0. toward "or from each other, the cushions being "guided onthe dovetail tongue N? of the table N It is understood that when the cushions O and O are moved apart, the face of the patient can be readily accommodated between the cushions at the time the patient is supported face' downward on the rests F, G. and H. An auxiliarylcushion O is mounted on the lower end ofthetable N and extends entirely across the same'to support the chest of thepatient when the latter is supported in face-down position on the table.

The abdominal rest G is in the form of a cushion G mountedon astandard Gr (see F ig. 4:)- formed of'tubular telescoping, sections G G and G, of which the telescoping section G is provided at its bottom with a cap G and is provided at its sides with transverse trunnions G mounted to turn in abase T slidably mounted on the side beams D of the table frame: D. Torsion springs T. connect the base T with the trunnions G to normally hold. the standard G in upright position but to allow the standard to swing in a lengthwise direction. The telescoping sections G .G* and G are held normally in an extended position bya spring T arranged within the sections and bearing with its upper end on the closed top of the section G while the lower end of'the said spring T rests on a plate T engaged by a setscrew T screwing in the cap G to allow of adjusting the tension of the spring T by screwing the screw 'rod T up or down in the cap G The base T can be readily disengaged from the side beams D whenever it is desired to remove the abdominal rest G, that is, when it is desired not to use the said rest.

' material.

The body rest H, shown in detail in Fig. 3, is in the form of a cushion H having its bottom H made of wood or other suitable The body rest H is vertically adjustable on a carriage H mounted to slide lengthwise on theside beams D of the table frame D. The carriage H is provided at opposite sides with clamping levers H adapted to engage the side beams D to lock j the carriage in position after the same-has slidably engaging the sidewbeams D .or the table frame 1), as plainlyindicated in Fig. 8. Y The bars I are pressed on at their forward ends by springs .I held within the hollow side beams D. The side beams I are provided with ratchet teeth I engaged by pawlsI held on levers I fulcrumed on the -beams D i'and pressed on by springs I to normally hold the pawls I in engagement wlth the ratchet teeth'I witha view to'hold" the rest against an outward movement by the action of the springs I". -When the frame D swings from vertical into horizon-. tal position then the forward ends of the levers I are adapted to move in engagement with the cam lugs B formed onthe upper ends of the standards B. By the. arrange ment described the leversI swing toward each other against the'tension of the springs I and thereby withdraw the pawls I from the ratchet teeth I to allow the springs I to push the foot rest I outwardly. \Vhen the rest I is in innermost positionand the table frame is in upright position" then the rest I is close to the floor to allowthe patient to readily step onto the foot rest I and when the table frame D has been returned to normal horizontal position and the patient is supported on the rests F, G and H then, the.

rest I is automatically released, as above described, andmoves into outermost position and away from the patients foot, thus'preventing the patient from straining the body during the time the adjustment is made. In

order to return the foot rest Iautomati cally to innermost position after the adjust- I ment is completed, use is made of'a chain- Q attached at one end to the foot rest I and extending forwardly over a pulley Q" journaled in arms I) forming part of-thecross' piece D", as shown in Fig. 8. The forward end of the chain. Q extends downward from" the pulley Q and is attached to -a crossbar B forming part of the standard Br] hen the table frame D is s\\-'ung-int0 horizontal position withthe foot rest I in forward position then the chain Q becomes slack owing to the downward swinging of the pulle'y Q,

and when the foot rest I is released and moved rearward as above explained then the chain Q is drawn taut. \Vhentlie table frame D is swung from horizonta position into upright position the pulley Q. also swings upwardly and in doing so it exerts a pull on the chain Q whereby a pullis 'exerted onthe foot rest I, todraw the latter upwardly into position for supporting the feet, of the patient at 'thetime theframe D nears an upright position. It isu'nders'tood I that when the foot restlI'is drawn upwardly as above described, it is 'automatically'locked in place by the pawls I engaging the ratchet Tithe levers I at this time being free. of the tion by their springs .1 The foot rest is cam lugsvB are pres-sedlinto' locking posi;

now again in position to support the pa tients feet when the table frame reaches an upright position, to allow the patient to conveniently step off the foot rest.

From the foregoing it will be seen that, by the arrangement described, the patient can be readily positioned on the table without discomfort and with the least physical exertion on the part of the operator. It will also be noticed that the various rests F, G, H and I can be readily adjusted lengthwise on the table frame to suit the stature and weight of the patient, and if the patient is supported face downward then provision is made for free breathing by supporting the head between the spaced cushions O and 0'.

Although I have described the table for chiropractic purposes, it'is evident that it can be used by surgeons and other practitioners.
