The table or body support and the frame on which it is pivotally mounted are both collapsible for adjustment from the open operative position shown in Figs. 1 and 3, to the closed inoperative position shown in Fi 2 lhe supporting frame comprises a pair of parallel top rails 2, 2, and a pair of parallel base rails 33, 3, the top rails being connected with the base rails by a plurality of pairs of diagonally arranged cross-braces 4, 4:, which are hinged at their ends to the rails, as at 5, and pivoted together at their points of intersection, as at 6. Such connection of the cross-braces with the opposite side rails permits of the latter being brought or folded together laterally. In order now that the upper rails may be folded down against the lower rails and the whole supporting frame be caused to assume the small compact form shown in Fig. 2, the hinge members between the cross-braces and the rails are connected to the latter by pivots, such as 7, which are arraiunul tYflDSVEETSQly of the rails to permit of the c oss-braces swinging in a direction longitudinally of the rails, as will be understood by reference to Fig. 2.

."is a means for controlling the opening and closing of this collapsible supporting frame, I have connected the upper and lower ails at each side of the frame by a plurality of pi voted, links 8 which are somewhat longer than the distance between the upper and lower rails when the frame is in open position, as shown in 1, whereby, upon the closing or collapsing of the frame, the upper rails will be caused to move longitudinally a sufficient distance to draw the upper and lower ends of the cross-braces, and thereby the connected rails, together laterally. in this way, downward pressure upon either one or both of the top rails will cause a collapsing of the frame both vertically and laterally, while an upward pulling of either one or both of said top rails will likewise cause a similar opening up of the frame in l'lOl'll directions.

fhiitably mounted upon this collapsible frame for tilting movement is the table proper. adapted to support the patient, said table, as here shown, comprising two side rails l1, l1. carrying an intermediate strip ofcanvas or like material 12 This table maybe pivotally mounted on the supporting frame in any suitable manner. In the present case. the top rails of the supporting frame are each provided at one end thereof "with a pair of spaced bracket plates 14, 14, carrying a pivot 15, upon which the opposite side rails ii of the table are fulcrumed.

It w ll be ui'iderstood that by reason of the connection of the side rails of the table with the side rails of the supporting frame, the table will be opened and collapsed with the opening and collapsing of the frame,

this being permitted so far as the body support 12 is concerned by reason of its flexibility. As a means for holding the table in its open position, the side rails of the same are connected. at their ends by hinged crossbars 17.

The mechanism for tilting the table comprises a segmental rack 20, rigidly attached to the table by suitable fastening means such as the bolt 21, and a cooperating pinion 22 carried by a shaft 23 jourualed to one of the upper rails of the supporting frame; the rotation of said pinion acting through the rack 20 causing the table to rock on its fulcrum support 15. As here shown, the shaft 23 is journalled in a bearing sleeve 2%, which extends through transverse openings in the frame rail 2 and the bracket plates 14L, 14, at opposite sides thereof, and is clamped in connection with the frame by means of a head 25 at one end. thereof engaging one bracket plate and a nut 26 threaded on its other end for clamping engagement with the oppositebraclret plate, as clearly shown in Fig. 4.

The pinion 22, in accordance with the present invention, is connected with the shaft 23 in a manner which will assure its being operated by the shaft to raise and lower the tal'ile under normal loads thereon, but which will permit of its turning relatively to the shaft under any overload on the table and thereby avoid possibility of damage to the apparatus through undue strains or breakage of the parts. Such connections between the pinion and shaft is a frictional one and is obtained by the following means: The pinion is loose on the shaft and has secured to opposite sides thereof, by fastening pins 29, two steel discs 28, 28, which are also loose on the shaft. Between these pinion discs 28, 28, and a pair of discs 30, 30, keyed to the shaft, are friction washers 32, of brass or like material, two of these washers with an interposed spacing washer 31 being shown at the outer side of the pinion, and one washer being shown at the opposite or inner side of the pinion. By causing a frictional engagement between these discs 30 and 30 keyed on the shaft 23, and the discs 28, 28, fastened to the pinion 22, it will be understood that rotation of the shaft will beimparted to the pinion. Such a frictional engagement may be effected by any suitable clamping means. the means here shown for the purpose comprising a shoulder 36 on the shaft against which the outer disc 30 bears. and a (o-operating compound adjusting nut 37 threaded onto the outer end of the shaft and a ting through a spring washer 38 (and certain intermediate braking members to be hereinafter referred to) against the outer disc 30.

Now in order to hold the shaft against rotation under the weight of the table and its ill) Hill

load, I have provided a braking means comprising a stationary disc 3a surrounding the shaft at a point between the disc 30 on one side and an end disc 39 on the other side, both being keyed on the shatt, and friction washers 34, 34. interposed between said discs as shown. By causing su'lticient t'ric tion between the stationary disc 3ihere shown as carried by a bracket arm at tached to the trameand the discs 30 and 539 keyed on the shatt it will be understood that the shaft will be held against turning movement except that produced by its op erating means, hereinafter described. The means here shown for effecting the desired friction between the members of the braking means comprises the adjusting nut 37, which, in the arrangement of parts shown, is operative to effect the proper adjustment of both the shaft braking means just described and also the trictional connection of the pinion with the shaft.

Pivotally mounted on the outer end ot the shaft 23, or that end opposite the pinion carrying); end, is a tubular operating lever 40 having a pawl and ratchet connection with the shatt tor imparting rotary move ment thereto, the pawl, indicated at a l. be ing carried by said operating lever, and the ratchet, indicated at 42, beinp; keyed on the shaft and dctachably held thereon by a nut 13, threaded on the outer end of the shaft and cl amping the ratchet against a shoulder thereoir as clearly shown in Fig. 4.

The pawl 41 is a double one being pivoted at its center on a pin a t-in order that it may be caused'to engage at either end with the ratchet teeth according to the direction of rotation to be imparted to the shaft 23 and attached pinion 22 for controlline the raising and lowering movements of the table.

As a means for controlling the action of the pawl to cause either one or the other ot its ends to engage the ratchet teeth, according to whether the table is to be raised or lowered, I mount an elbow lever 4:5 on a pivot 46 within the tubular lever ll) for engagement. through a projecting springpi essed ball 47 at its lower end, with the upper edge of: the pawl ll at either side of its center; this device being; operative toyielding'ly hold the particular end of the pawl with which it engages in operative relation. with the ratchet 42. as will be clear by reference to Fig. 9. For shitting this elbow lever to either end of the pawl. it is engaged at one side by a spring 48 supported on a pin 919 within the tubular lever 40. and at its opposite side by thelower cud ot a rod 50 which is supported tor longitudinal slidinp; movement in suitable bearings 51. in the lever 10 with its upper end in engagement with a cam lever 52. which latter is pivoted at 53 in the upper end of the lever 40 and provided with a handle portion projecting outwardly through a slot 55 in the lever in a convenient position to be manipulated by the patient on the table. By turning;- this cam lever in any one direction, it will act through the rod 50 to hold the lever 4:5 in operative relation with one end or" the pawl, and by swinging said cam lever in the opposite direction, it. will permit the lever 45 to be shifted by the spring; 48 to a position o't operative relation with the opposite end of said pawl.

In order to assure the operating lever 4L0 being held in raised position where it may be conveniently grasped by the operator, means are provided for maintaining a frictional connection between. the same and the shaft on which it is mounted. This means comprises two fibre washers, and (3].. seated within annular depressions in the opposite sides of the ratchet 4:2 and acting against adjacent parts ot the lever under the intluence ot a series of coiled springs 62 which are seated within transverse openings 3 in the ratchet, as shown in, Figs. 4t and 9. One of these washers, that indicated at. (it), bears directly against one inner wall of the lever, while the other washer, indicated at. 61., acts against the opposite inner *all. of the lever through an interposed disc 65 to be hereinattter reterrcd to. With this 'lilhZl'lOlltll connection between the lever and the ratchet the latter being; keyed to the shaft-the lever will be maintained in its upright position when released by the operator, although of course capable of being moved downward and out of the way when so desired.

In order to obviate the clicking; noise incident to the use of a pawl and ratchet, which. noise is objectionable to highly ne.r vous persons, I have provided a so-called silencer. llhis comprises the disc 65, which is interposed between the washer (3t and the adjacent wall of the operating lever 40 and provided at one side thereof with a lug 6 engaging the lever within an open ing 7 therein, whereby the disc will be caused to turn with said lever, and at its opposite side provided with two guardlips 68, GS. positioned, adjacent the opposite ends ot the pawl 41. tor preventing engagement of the same with the ratchet upon the bac rward or reverse stroke ot the lever. Rc'l'erring to l ig. 9. it will be noted that one end ot the pawl is in engagement with the ratchet and that the lug: 66 on the disc 85 is in contact with one wall ot the opening: 61' in the lever 40.

The several. parts in these positions are ready tor a forward or operative stroke at the lever. its this stroke takes place, the parts will maintain toe same relative positions the engagement oi the lug; 66 on the disc (35 with the wall of the opening; in the lever causing); said disc to be retatd torwardly with the lever.

Now upon the reverse stroke of the leverbearing in mind the fact that the friction between the disc and the ratchet with its fibre washer 60 is greater than that between the disc and the lever whereby the disc will be held to the ratchet and so permit movement of the lever relative thereto-the pawl will first ride up onto the adjacent ratchet tooth and also onto the adjacent guardlips, 68, by which latter it is prevented from dropping into the space between the ratchet teeth. During such backward movement of the lever to bring the pawl onto the guarddip, it will have advanced sulliciently to bring the opposite wall of its opening 67 into engagement with the disc lug 66, as shown in Fig. 13, after which the parts will move together with the pawl held from contact with the ratchet teeth by the engaging guard-lip 68. Now upon the succeeding forward stroke of the lever, the disc 65 will be held stationary until the pawl has been moved forward ol the supporting guard-lip and into engageuient with the next ratchet tooth, at which time the rear wall of the lever opening 67 will have advanced into engagement with the disc lug 66, as shown in Fig. 9, after which the parts will move together as l'iereinbe'l ore described. It will of course be understood that both guard-lips G8 co-operate with the adjacent ends ot the pawl 41 in like manner.

The means for indicating to the patient the angle of inclination to the horizontal at which the table is tilted, comprises a pair of striking devices, one being operative on the downward movement of the table and the other on the upward. movement of the table, and a single operating mechanism. common to both said devices. The striking devices comprise two oppositely located sound plates 70, 70, mounted on one of the side rails L1 of the table, and co-operating strikers 71, 71, the said sound plates being here shown as laterally projecting flanges of a supporting plate 72 bolted to one side of the said rail, and the strikers being each pivotally mounted on. a short sha'tt T3 which is carried by an adjustable support 74 pivoted. at 75 to an outer bearing plate 76, also bolted to the rail 11, as shown in Figs. 5, 6, 7 and 8. A spring 77 connecting with rear extensions of the strikers serves to normally hold the latter in contact with the sound plates, and to snap them into striking contact therewith when drawn back ward and released. For rocking the strikers on the shaft 73 is a T-lever 78 mounted 011 said shaft 73 with two arms arranged for engagement with pins '79, 79, on the opposite strikers, as shown by dotted lines in Fig. 8, and its third arm having a pin 80 adapted to be engaged by pins 81 on an actuating wheel 82. Rotation of this wheel .to indicate a movement of live degrees.

82 in one direction, as effected by the lower ing of the table through means to be hereinafter described, causes each successive pin thereon to engage the pin SO on the lever 78 and rock the lever and one ot the engaged strikers in a direction to withdraw the striker from contact with its co-operatirw sound plate, and, after said pin 01 the wheel 82- in its continued advance releases the pin 80, the striker will be snapped back into striking engagement with the sound plate under the action of the spring 77; this return of the striker also operating to return the lever 78 to its normal position shown in Fig. 8. Rotation of the wheel 82 in the opposite direction, as effected by the raising of the table, will act through the lever 78 to cause a corresponding operation or the opposite striker, as will be clear by reference to Fig. 8.

T he means here shown tor operating the strikers in the way described, comprises a stationary gear 85 mountedon the table pivot 1.5 and meshing with a pinion 86 on a shaft 87 carried by the table rail ll, which shaft also carries a gear 88 meshing with a pinion 89 on the shaft 90 which carries the striker actuating wheel 82. With this means, it will be understood that the actuating wheel. 82 will be automatically rotated in one direction upon the lowering of the table and in the opposite direction upon the raising of" the table.

As shown in Fig. 8, the wheel 82 provided with one series of concentrically ar ranged pins bl so spaced as to effect a striking operation. at each change a single degree in the angle of inclination to the horizontal at which the table is tilted. It will be obvious, however, that these striking pins may be variously arrangeo to indicate different degrees of movement as may be desired. For instance, the wheel is shown as provided with two pins 91, 91, outside of: the circle of the series 81, which are arranged In order to adjust the pin 80 on the lever 78 for co-operation with either one or the other of the two sets o'l" actuator pins 81. and 91, the pivoted support 74- ior the shaft 73 and parts mounted thereon, is held by a spring 99, with a washer 93 on said shaft in contact with an adjustable eccentric pin 9 (see Figs. 7 and 8), whereby, uponthe proper adjustment of said eccentric pin, the support 7i may be shifted to adjust the lever 78 and its pin 80 with respect to the pins on the actuator wheel 82. By shifting the support 7% to its extreme rear or left-hand position, the pin 80 will be moved entirely out oi the path of: the actuator pins on the wheel 82 and so render the indicator or striking mechanism wholly inoperative when so desired.

The adjusting eccentric pin 94- may be supported and operated in any suitable or desired way. its here shown (see Fig. 7) it is carried by a head rotatably mounted in a socket no in the rail 11, and engaged by one end of a shank 97, which latter at its outer end connects with an operating button 98 rotatably mounted in a bearing plate 99 at the Face side of the rail 11. A springpressed hall. 100 carried by the button and engaging the face ol the bearing plate 99 within suitably spaced depressions 10.]. therein. serves to yiehlingly hold the button and the associated eccentric pin 94: in adjusted position.

A coiled spring; 102 interposed between or side of the button 98 and the eccentric head 95 operates to hold the latter to its seat in the socket 96.
