To all whom it may concern:

Be it known that I, FRANK KOENIG- KRAMER, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Treating-Tables, of which the following is a specification.

My invention relates to improvements in treating tables. One of its objects 1s to provide an improved vertically adjustable table, the respective top sections of which are independently supported and adjustable upon the vertically adjustable section of its supporting column. Another object is to provide a table having independently movable and adjustable top sections and 1mproved mechanism to movably support and adjust the respective top sections. Another object is to provide a table having a top section with a variety of different movements, and means to enable said several movements to be employed separately or conjointly. Another object is to provide a table having a movable section yieldingly sup ported upon a vertically adjustable standard and improved means to vary and adjust the tension thereof. Another object is to provide improved means to tension and limit the movements of the movable top sections to restrain or to prevent excessive or too free a movement thereof. My invention also com prises certain details of form, combination, and arrangement all of which will be fully set forth in the description of the accompanying drawings in which:

Fig. 17 is a top plan of the head F and parts mounted thereon.

The accompanying illustrations represent the preferred embodiment of my invention in which A represents a base, having extensions a. B a column vertically ad ustable relative to said base, and C, D, and E independent table top sections each supported upon and adjustable relative to said column B.

The column B may be adjusted relative to the base A in any desired manner. I have illustrated said column as a piston seated in a vertical cylinder in the base A, relative to which it is vertically adjustable hydraulically by reciprocating the handle, 2 of a hydraulic pump contained within sald piston. A brake shoe 3 forced against the outer face of the piston by means of a set screw 4: threaded through an ear of the base A serves to rigidly lock the piston in its adjusted position to retain the piston in place for long periods.

At the upper end of the piston B is an extended 0r enlarged head F having a depending arm 5 which is bored to receive a vertical shaft 6, and is provided with a rectangular bar 7 which seats in a corresponding groove in the side of the base A to prevent the column B and head F from turning or rotating relative to the base A. At the upper end of the shaft 6 is a head or block 8 rigidly locked to said shaft and resting upon the upper face of the head F. At the lower end shaft 6 is provided with a collar 9 held in place by a set screw 10 threaded through an ear 11 of the arm 5 and into said collar and in position for the point of said set screw to selectively engage one or more holes in said shaft 6 to lock the shaft to adjusted position and against rotation. Below the collar 9 is a block or collar 12 rigidly locked to shaft 6 by a set screw.

The table top section C is designed to support thehead and shoulders of the patient, and is pivotally attached upon a horizontal axis at 14 on opposite sides to arms 15 of the head F. Bars 16 are attached to a-projection 17 of the head F and extend outwardly parallel to each other beneath the section C. At the outer end of said bars-l6 is a pivotally supported gripping head or stirrup 18 which has a recess through whichpasses a bar 19 which is hinged at 20 to the under side of the section C. The bar 19 has stops 21 to limit its movement through the stirrup 18 and said stirrup has a block of hardened steel 22 which tends by the gravity action of the stirrup 18 to automatically grip the bar 19 and prevent it from passing downwardly through the stirrup. If desired a spring 24 may be employed instead of relyingupon gravity to'cause'the' stirrup to grip the'bar 19. The bar 19 moves freely in the opposite direction through the stirrup. I also preferably provide a series of perforations in the bar 19 set at regular intervals apart, and by means of which and a pin inserted through one of said perforations above the block 22 said bar 19 may-bepe'rmanently locked to any desired position. For ordinary adjustments of the section 0 upon its centers 14, the operator may lift the outer end of section C to any desired position of inclination when the'block 22 will automatically grip the bar 19 and hold the section in place, or if'it is desired to move section 0 to a position of less inclination the operator takes a hold of the outer end of section 0 with both hands and by pressing on the lever 25 of the stirrup with his knee releases the engagement-of block 22 with bar 19 and lowers the section C to the desired position when the block 22 automatically reengages bar 19.

The table top section D is designed to support the hips of the patient and to have a pivotal movement upon a vertical axis or pin 29, and also to be inclined or tilted upon a horizontal axis approximately above and intersecting said vertical axis, whereby said section D may be adjusted and held to either a horizontal or an inclined position. The section D has downwardly projecting cars 27 by means of which it is pivoted upon a horizontal axis to the frame 28. The frame 28 has a downwardly projecting pin 29 which seats in a recessbored in the up er end of shaft 6. The under face of frame28 rests upon the head 8 adjacent to the pin 29, and the arm 30 of frame 28 rides'so close to the projecting end 31 of head 8 as to engage therewith when section Dis subjected to a heavy weight, therebv preventing the pin 29 being bent or unduly strained.

A crank shaft 32 is journaled to the frame 28 with one end 33. projecting to be grasped by the operator while the crank pin 34 at the other end of shaft 32 engages and travels in a slot 35 formed between the angle plate 36 and the flat plate 37. Said plates are held in position to the underside of section D by means of screws 33 on the shanks of which are springs 39 which yieldingly hold the plate 37in engagement with the crank pin 34. In the position of the crank indicated in Fig. 11 and in full line Fig. 12 the section D is inclined, while in the position Fig. 10 and dotted lines Fig. 12 the section Dis in a horizontal position. There is suflicient frictional engagement between the plates 36 and 37 and crank pin 34 to cause the shaft 32 to retain whichever position it is adjusted to.

The table top section E is supported upon a frame 40 relative to which it is adjustable endwise, and also pivotally. with the axis of its adjusting screw as a center. The frame 40 is pivotally supported upon a horizontal axis at 41 relative to the head 8 and yieldingly tensioned so as to secure a reciprocating or rocking motion of the section E about said axis 41. A screw threaded rod 42 is journaled in brackets 43 and 44 attached to the section E and engages the central threaded boss of the cross bar 45 of the frame 40 to feed the section longitudinally of the frame 40, said screw being rotated by. hand by means of the crank 46. A shaft47 concentric with the screw rod 42 is j ournaled at oneend in the bracket 44 and at the opposite end in a bracket 48 also attached to-the section E. Cross bars 49 and 50 are rigidly secured-by set screws to the shaft 47 between the brackets 44 and 48 so as to rock with said shaft in its bearings The longitudinal rods of frame 40 pass through eyes in the cross bars 49 and 50 and slide longitudinally therein when the section is adjusted by the screw rod Rubber buffers or stops 51, carried by bracket 48, engage the ends of the cross bar 50 and noiselessly limit the rocking movement of the shaft 47. The bracket 44 is provided with an annular projection 52 which is en aged by a shoe 53 held in engagement therewith by a set screw 54 carried by the crossbar 49, said shoe serving to prevent the shaft 47 from rocking too freely in. its bearings w hich action may be varied byv adjusting the set screw 54. A hand lever 55 is pivotally attached to section E at 56 and is provided with projecting arms 57 which may be shifted into and out ofengagementwith the cross bar 49 to lock the section Etoa' horizontal position above'and relative to the frame 40, by preventing rocking motionof the shaft 47 and its cross bars 49 and 50.

The rotary movement of the shaft 6 in its bearing 5 provides for swinging the section E in horizontal planes backward and forward, and this movement is preferably limited and said section returned automatically to a central ornormal position by means of a spring 60 attached at one end to a link 64 pivoted to the projection 31 of the head 8 and at the opposite end to a threaded eye-bar 61 adjustably connected by a nut 62 to a bracket 63 attached to the projection 17 of the head F, whereby any desired tension on spring 60 may be secured.

In order to adjustably tension the movement of the table section E and its frame 40 upon the center 41, and to lock said section E against movement upon said section I provide a frame 68 substantially parallel with frame 40 and pivotally attached at 66 to the collar 12 carried by the shaft 6. A. spring shackle 67 is pivoted to a carriage 68 which rides on the frame 65, and is adjustable thereon by means of the screw rod 69. The screw rod is rotatably mounted in a block 70 pivotally attached at 70 to the side bars of frame 65, and is adjusted by means of a hand wheel or crank 71. Another spring shackle 7 2 is pivotally attached at 7 3 to'the head 8. Said spring shackles, see Fig. 6, are provided with a plurality of eyes to be engaged by a plurality of coiled springs 74 which springs tend to pull the frame 65 upwardly toward the frame 40. A threaded eye-bar 75 is pivoted upon a cross rod 76 of the frame 40, and a nut 77 threaded thereto engages a tube 78, see Fig. 7, which tube has forked arms 79 at its lower end pivotally connected to the center 70 of frame 65, thereby enabling the nut 77 to be adjusted to force the frames 40 and 65 apart against the action of the springs 74, and also serving to transmit the tension of springs 74 into force tending to lift and support the frame 40 and parts carried thereby. Downward movement of the nut 77 on the bar 75 tends to lift t 1e outer end of section E to a higher point, or to elongate the springs 74, so that adjustment of the nut 77 may be made to substantially counterbalance variable weights to be supported by the section E. The movement of the carriage 68 to or from the base A also serves to increase or diminish the tension of the springs and to increase the leverage of the springs 74 tending to lift the frame 65, and through the rod 75 the frame 40 and section E, thus providing an increased range of counter-weighting support for the section E.

As illustrated in Fig. 7 the lower end of rod 75 is guided in the tube 78, with the nut 77 and tube 78 only in a thrust engagement leaving the section E free to be lifted still farther by hand with the nut 77 out of contact with the tube 78. In the modification Fig. 8, however, an inner sleeve 80 is rotatably mounted in the tube 78 and the rod 75' is threaded to said sleeve 80, which may be turned by its hand. wheel 81 to feed the rod up or down within the sleeve 80, while the nut 82 is employed as a stop or lock nut.

In order to lock the section E against pivotal movement upon the center 41 I provide a depending arm which is pivoted upon a cross-bar 19 of frame 40 and its lower end interposed between one of the bars of frame 65 and a strap 92 locked at one end to said bar 65 upon the bolt 70. At the opposite end the strap 99 is seated. over a threaded stud 93, which is fitted with a clamping nut 94, by means of which the free end of arm 90 is clamped to frame 65 to lock section E in place. When unlocked the arm 90 slides freely up and down between the frame 65 and strap 92.

When the supporting members 75, 77, and 78 illustrated in Fig. 7 are employed in connection with the locking member 90 to transmit the resilient strain of spring 74 from the arm 65 to the auxiliary top section E, the member 90 forms a non-extensible connection between members 40 and 65, and hence with members 40, 65, and 6, forms a rectangular frame-work, which prevents the top E and arm 65 from rising above a predetermined position, depending upon the point at which member 90 is clamped to member 65. If however force downwardly is applied to the top E, sufficient to overcome the tension of spring 74, which variable by adjustment; the force will be transmitted from the top E through member 90 to arm 65, the members 7 5 and 77 will separate telescopically from member 78 sufficiently to enable the top E and arm 65 to be yieldingly depressed to a limited extent, and when the downwardly directed force on the top E is released, the top E and arm 65 will return to but not above the predetermined point. Adjustment of the carriage 68 will predetermine the amount of force downwardly on the top E which will be necessary to effect this downwardly yield ing movement of the top section E.

The top section D is locked against rotation upon its center 29 when desired by means of a bar 95 sliding endwise relative to and across the top of head F. Said bar is actuated by a pivoted hand lever 96, and has upwardly projecting lugs 97 and 98, one of which engages a notch 99 in one arm of the frame 28, while the other engages under the opposite arm of frame .28, and in the locked position both serve to support the section D and to relieve the shaf 99 from strain.

My improved table is thus capable of being adjusted to secure a soft pliable flexi ble movement of the table section E. and adjustment thereof to correspond to the weight of the different patients. Said section has an endwise movement, a rocking movement and a pivotal movement, each of which may be locked or used independently of or in conjunction with the section E, and its separate adjustments employed independently and locked when not required. All the table top sections are also supported upon and adjustable relative to a common standard or support Which is itself vertically adjustable to secure the desired position of the patient verticallv.

When the top section D is locked to the head F it becomes, in effect or for practical purposes, a part of the section C. When the section D is unlocked from the head F and the forward or adjacent edge of section E is practically in engagement Withthe straight edge of section D, the sections D and E move in unison upon the shaft 6 as a center practically as a single section, While When section D is free to move and section E is adjusted to leave a considerable gap between sections D and E each of the three sections are practically free and independent of each other.
