OSTEOPATHIC TABLE.

Specification of Letters Patent.

Patented Nov. 26, 1918.

To all whomit may concern Be it known that we, JoHN V. MoMANLs and \VAmu-zn L. Snnnwooi), citizens of the United States, respectively residing at Dayton, in the county of Montgomery, State of Ohio, and Kirksville, in the county of Adair, State of Missouri, have invented certain new and useful Improvements in ()steopatbic Tables, of which the following is a specification.

This invention relates to tables for use by osteopathic practitioners in treating patients by moving or stretching various parts of the human body. The primary object of the invention is to provide a table of the class set forth embodying mechanical structures which permit a multiplicity of adjustments and movements with ease of manipulation to effect a. correction and cure of physical irregularities and to provide for relieving any friction on the chest of the patient when treating him while face downward during movement of a portion of the table. A further object of the invention is to provide an auxiliary section for an osteopathic table with a spring means operating in a substantially vertical direction relatively thereto and adjustable or shiftable to change the position thereof relatively to the under side of the auxiliary table section to increase the strength of the spring without compressing the same for the purpose of accommodating patients difl'ering in weight and at the same time maintain the normal or desirable elasticity of the spring. A further object of the invention is to provide an osteopathic table with a main table section, an auxiliary table section, and an intermediate section or drop leaf which is movable only with the auxiliary section when the latter section is in fr'ctional contact therewith.

ith these and other objects and advantages in view the invention consists in the preferred construction and arrangement.

of parts which will be more fully hereinafter Fig. 8 is a transverse vertical section taken in the plane of the line 88, Fig. 1, looking in the direction of the arrow.

Fig. 9 is a detail perspective view of the casting mounted on the top of the pedestal.

Fig. 10 is a detail perspective view of a portion of the drop leaf or section casting and the locking means therefor.

The support of the table comprises a base 5 of any suitable extent and a tubular upright 6 having a casting 7 fixed on the upper end thereof, the parts 5, (5 and 7 forming a pedestal on which the remaining parts of the table are mounted. The table embodies a table 8 having a hinged main or head section 9, an intermediate drop leaf or section 10 of semicircular form, and an auxiliary section 11 for supporting the lower portion of the body of the patient. The casting 7 is preferably of the form shown by Fig. 9 and has laterally projecting arms 12 at diametrically opposite points and an intermediate longitudinal arm 13 converging toward its outer extremity and provided with -a catch pin 14 extending at right angles therethrough. The head section 5.) of the main table section 8 is hinged through the medium of angle members 15 secured thereto and provided with pendant arms 16 fulcrumed against the end of the arms 12 of the casting 7. To maintain the adjustment of the head section 9 a hanger or bracket 1'? depends from the under side thereof and has a notched lever 18 pivotally attached to the lower extremity thereof and embracing the reduced outer end of the intermediate arm 13 so that the notches 19 of the said levcr may engage the opposite projecting portions of the catch pin 14, as clearly shown by Figs. 1 and 2. Through the adjustment of the notched lever 18 the head section 9 may be raised and lowered as desired to accommodate the patient lying on the table. As clearly shown by Fig. 2, the intermediate drop leaf or section 10 has its semicircular edge 20 adjacent to the inner cud of the main table section 8 and the latter is formed with a semicircular recess 21 so as to permit free movement or lateral'swing of the inter mediate drop leaf or section 10 when such operation of the latter leaf or section is desired to be etleet-ed. The drop leaf 'or section 10 is supported by a casting or bracket 2:2 formed with opposite parallel rests 25 with upper downwardly inclined edges 24, the said table having depending angle hangers 25 applied against the outer sides ot the rests 23 and pivoted to the latter by suitable devices. The rests 23 are connected by a cross-bar or member 26 having at the center a depending post 27, see Fig. 10. loosely fitted in a socket 28 secured to a part of the supporting frame or casting member for the adjusting devices controlling the position of the spring for sustaining the auxiliary table section 1'l in proper position when patients of different weights are placed thereon. The socket member 28 is provided with a tubular member 29 which depends therefrom and engages an opening 30 extendin through a central pro ection or boss 31 ()lll'lOd as a )art of the inner edge of the casting 7. lfixtending upwardly into the tubular member 29 is a post 32 which is held in a bracket 33 secured to a part of the support of the table at a suitable distance below the casting 7, and on the said post 32 above the bracket 33 and resting upon the latter is a sleeve. 34 of a bracket 35 for the lower end of the'spring which is arranged to resist vertical movement of the auxilia table and which will be more fully hereinafter described. It will be seen that through the medium of the bracket 33 and the sleeve 34 the lower end of the 0st is rigidly supported and said post Wlll have -a dimension proportionate to the parts cooperating therewith to resist the maximum strain imposed thereon during the operation of the auxiliary table section 11. The socket casting or member 28 is free to be moved in opposite lateral directions on the upper end of the post 32 without shifting or moving in the least the semicircular drop leaf sec- .tion 10, and to effect this result or to permit the auxiliary section to be noved inde endently of the intermediate or drop lea sec- .tion 10 the post 27 is made structurally independent of the post 32 and is loosely held within the socket 28, as clearly shown by Fig. 3. The socket member 28 is also rovided with an attaching arm 36 exten ing outwardly therefrom over and above a portion of the cast-ing 7, and to the free end of this arm a resistance or tension spring 37 is secured and also adjustably connected to an angle plate 38, through the medium of an adjusting link 39, fixed to the center of the casting 7. This spring is primarily tensioned hold the auxiliary section in normal position or longitudinal alinement with the main table sectionB and intermediate or drop leaf or section 10, and when the auxiliary section 11- is swung in op posite lateral directions such movement thereof is against the resistance of the spring the auxiliary section is swung laterally.-

The inner endof the combined socket and device 28 is formed with a transversely extending knuckle 40, and embracing the. opposite ends thereof and pivotally connected thereto by a pin'41 are extensions 42 of an adjusting frame 43 suitably secured to the supporting frame 44 of the auxiliary table section 11, the adjusting frame 43 being formed with an upwardly inclined inwardly projecting guide 45 and an outer depending screw-eye or lug 46. The parts are so proportioned and primarily constructed that a line drawn longitudinally through the center of the screw-eye or lug 46 and continued upwardly and inwardly will intersect the center of the pin 41. A screw-rod 47 with an outer hand-wheel 48 is mounted in the screw-eye or lug 46, and to the inner end thereof a coupling 49 is swiveled, said coupling being in the form of a sliding yoke which has its upper edge portion held in close' contact with the under side of the guide 45, and within this yoke the upper end of a rod 50 is pivotally mounted, said rod constituting the shifting or adjusting means for a compression spring 51 whic controls the resistance to vertical movement of the auxiliary table section 11. This rod 50 moves uniformly with the yoke 49 and the latter is shifted inwardly and outwardly by the operation of the screw-rod 47, the latter holding the yoke in sliding engagement with the upwardly and inwardly inclined guide 45. The lower portion of the rod 50 is reduced and freely movable through an enlarged flared opening 52 formed in a horizontal plate 53 projecting from the sleeve 34 and reinforced by an angle member 54 also extending from said sleeve and integrally formed with the plate The lower portion of the rod 50 also slidcenter of a rocking disk 56 havin diametrically opposed depending ears 5 resting on the'opposite side edges of the plate 53. the said rocking disk 56 bein clearly shown in detail by Fig. 6. The roc ing disk 56 is held a suitable distance above the plate 53 and has an upwardly projecting circular rib 58 to provide a seat for the lower end of the spring 5 The upper end of the spring 51 1s engaged by an adjusting cap nut 59 cooperating with screw-threads 60 formed on the upper portion of the rod 50. The lower portion of the rod' 50 ,is free to move through the opening 55 of the rocking 115 ably extends through an opening 55 in the disk 56 and the opening 52in the plate 53, the opening 55 of the rocking disk 56 being disposed over the larger openin 52 below and the lower portion of the rod 50 is not only permitted to move vertically to compensate for adjustment of this spring organization as a whole, but also laterally owing to the flared formation of the opening 52. The rod 50 together with the yoke 49, disk 56 and parts intimately co6peratin therewith, may be properl termed a s iftable Sustaining means for t e auxiliary table section, and theobject in view is to change the position of the sustaining means without compressing the spring or in the least modifying its normal adjustment to accommodate patients of different weights placed on the table and having the lower portions of their bodies engaging the auxiliary table section and whereby the elasticity of the spring 51 is maintained instead of resorting to compression of the spring as heretofore adopted in prior spring structures operating in connection with auxiliary table sections. By operating the spring in the manner specified a better advantage is gained and more sustaining power is acquired without resorting to compression of the spring.

The supporting frame 44 of the auxiliary table section extends longitudinally under the latter a suitable distance, as shown by Figs. 1 and 2, and embodies opposite frame bars connected at intervals and secured to the frame, and rising therefrom are uides 61 and 62 with. which depending gui es 63 and 64 secured to and extending from the under side of the auxiliary table section 11 have coiiperation with relation to a rotating adjusting rod 65 formed with an outer crank handle 66, the said adjusting rod freely moving through the guides 61 and 63 and swiveled to the guide 64. The rod 65 has a screw-threaded portion 67 which engagesa correspondingly screw-threaded opening 1n the guide62, and by turning the said rod in opposite directions the auxiliary table may be longitudinally shifted in opposite dlrections relatively to the intermediate drop leaf or section 10 to lengthen or shorten the table as a whole as may be desired. It will be seen that the supporting frame 44 is connected or essentially secured to the auxiliary table section 11 through the medium of the screw-rod 65 engaging the several guides, and, furthermore. through a horizontal or lateral shifting movement of the auxiliary table in opposite directions as Well as a vertical movement above and below a horizontal plane 1s permitted, the said auxiliary table being also provided with means for practically effect-- ing a universal movement thereof, and these various movements of the auxiliary table section are resisted by the springs 37 and 51, said springs always tending to bring the auxiliary table section back to normal position when released from operating pressure or force. a

The auxiliary table section 11 is also provided with means for holding it in canted osition at either side and also for locking it 1n horizontal position. These means comprise a pendant 68 secured to the frame 44 and having upwardl extending spaced members 69 through which the screw-rod 65 rotatably extends, the said members 69 forming fulcrum means relatively to the screwrod. In the lower end of the endant 68 is an inwardly projecting heade pin or stud 70 with which an adjacent locking segment 71 cotiperates. The segment 71 is in the form of a curved bar having one end pivoted to a transverse bracket 72 secured to the under side of the auxiliary section 11, as at 73, see .Fi 8. To the opposite end of the segment 71 a link 74 is also pivotally connected, the link being movably secured to the intermediate portion of an operating lever 75. The lever 75 is pivoted to the end of the bracket 72 opposite that to which the end of the segment 71 is secured, and by drawing upwardly on the said lever the said segment 71 will be elevated and by throwing the lever 75 downwardly the segment 71 will be forced into locking engagement with the headed stud 70 at the lower end of the pendant 68. The segment 71 is provided with a central notch 76 and notches 77 on opposite sides of the notch 76. By elevating the lever 75 and drawing the segment 71 upwardly to clear either of the notches from the headed stud 7 0, the auxiliary table section may be adjusted either to the right or left plane and its adjusted position retained without liability of displacement of the auxiliary table section during the movements of the latter in treating a patient. It will be observed that the adjustment of the auxiliary table section 11 as just explained may be effected without modifying the shiftable sustaining means as hereinbefore described. or in other words the sustaining spring and its cotiperating parts may be adjusted as required and the table section 11 may then be canted either to the right or left or disposed rearwardly and fixed in either position. This adjustment of the auxiliary table section 11 is .very advantageous in disposing the lower portion of the body of a patient at the best angle to rectify a bodv irregularity. The auxiliary table section may also be permitted to have a free movement in opposite lateral directions or a rocking motion may be imparted thereto by entirely releasing the segment 71 from the headed stud 70 of the pendant 68, this release of the segment being accomplished by releasing the lever 75 and through the link 74 correspondingly elevatiug the said segment. This uureta'rded or free movement of the auxiliary table sectioirll mav be found uecessauv in certain treatments and hence the means for holding the said table section either in a. horizontal position or in right or left canted positions is operable to etl'ect a complete release of the said table sect-Ion.

The lllt-Ll'lllt.(llillt drop leaf or section '10 held in a horizontal position relatively to the casting or bracket 22 on which it 1s mounted by a spring locking bolt 78 slid the body of the patient or to avoid pressure contact. with the intermediate port-ion ofthe body of the patient, particularly when laterally moving the auxiliary section 11 and at a time when the said'int-ermediato drop leaf or section 10 is not. laterally moved with thesaid auxiliary section; To prevent the intermediate drop leaf or section 10"from having lateral or oscillating movement in -a horizontal plane during the actuation or lateral movements of the auxiliarytable section 11, another look is provided and consists of a lever 80 movably mounted on the casting 7 and having an outwardly PI'O', jecting handle or arm 81 and an inner n pwardly projecting lip or flange 82 to engage a slot 83'for1ned in a flange 8i depending from one of the rests 23 of the casting or bracket 22, the flange 8-1 preferably depend ing from the rest 23 having the bolt opening 79 therein, as shown by Fig. 10, so that both locking means for the casting or bracket 22 will be located atone side of the table for convenience of the operator'in adjusting the intermediate drop leaf or section 10 as may be desired. As hereinbefore specified, the drop leaf or intermediate section '10 may be laterally moved with the auxiliary table section 11 when the inner edge of the latter is adjusted for frictional engagement or contact with the adjacent outer edge of the said drop leaf or section 10, and the lateral movement of the intermediate drop leaf or section may be carried on when it is held in horizontal position or lowered on the rests 23.

From the foregoing it will be seen that a multiplicity of adjustments of the auxiliary section 11 and the intermediate drop lea-f or section 10 may be made to accommodate tageous feature ot'the improved table, however, is the sustaining spring or resilient support for the auxiliary table section aml the construction whereby the latter may be varied or sliit'tethaud it is proposed toadopt any means for shifting the said spring or resilient sustaining means for the auxiliary section to vary the resisting tension of the auxiliary section without modifying the normal tension of the spring.

From the fore oing description the operation of the ta ile will be readily understood, and it is proposed to equip the table sections of the table, with or without laJterally m'o ving'o-r oscillating the intermediate drop leaf or sectionlO, and as hereinbefore specified the said drop leaf or section 10 may be maintained in a horizontal position or lowered at the Will of the operator in accordance with the requirement of the treatment. of the patient.

An osteopathic table comprising a main table section, a support carrying the main table section, vertically alining bearings on the support, a post journaled in said bearings, a member secured to the upper end of said post, an auxiliary table section connected to said member at one side of the latter, and a spring connected to said member at the opposite side of the latter adapted to exert a pull on said member in opposition to the canting action on said member caused by the said auxiliary table section.

43. An osteopathic table comprising a main table section, a support carrying the main table section, vertically alining bearings on the support, a post journaled in said bearings, a frame secured to the upper end of said post and movable therewith, an auxiliary table section connected to said frame on one side of the post, a spring connected to said frame at the opposite side of the post from the side to which the auxiliary table section is connected and being adapted to exert a pull on said frame thereby tending to ounteract the friction between said frame and its bearings in its rotative movement on its vertical axis due to the sagging tendency of the projecting table section carried thereby, and an intermediate table section carried by the frame and movable therewith and with the auxiliary table section on its vertical axis coincident with said post.

44. The combination in an osteopathic table of a support, a main table section car- I ried thereby, an auxiliary table section bein resales adapted to form a continuation of the main table section carried by the support and having a-corinection therewith permitting of a swingingmovement of the auxiliary table section both laterally and vertically in relation to the main table section, elastic means for resisting the lateral swinging movement of the auxiliary table section, elastic means for resisting a depressing swinging movement of the auxiliary table section, and means for locking the auxiliary table section against swinging movement in a lateral direction.

45. In a treating table a supporting pedestal, a main table'section carried thereby, an auxiliary table section mounted on the support and being adapted to have both lateral movement in relation to the main table section on a vertical axis and movement on a horizontal axis in relation to the main table section above and below the plane of the top, elastic means for resisting the downward movement of the auxiliary table section, and elastic means independent of the first said elastic means for resisting movement of the auxiliary table section upon its said vertical axis in either direction as it is moved laterally out of its normal position, said last mentioned elastic means being adj ustable to vary at the will of the operator the resistance to movement of the auxiliary table section in lateral directions out of its normal position.

46. In a treating table, a main table section, a support'therefor, an auxiliary table section mounted in operative relation to the main table section, and supporting means for the auxiliary table section comprising swivel connections permitting universal movement of the auxiliary table section in relation to the main table section, elastic means constantly operating to hold the auxiliary table section in a-normal or centralized position on its vertical axis andresisting movement in eitherdirection from said normal or centralized position upon said vertical axis, said elastic means adjustable to vary the resistance offere to movement of the auxiliary table section on its vertical axis at the will of the operator, and a second and independent elastic supporting device for normally sustaining the plane of the top of the auxiliary table section in the plane of the top of the main table section, said last mentioned elastic supporting means being adapted to resist movement of the auxiliary table section only in the downward direction out of the plane of the top of the main table section, the last said elastic supporting means being adjustable at the will of the operator for varying the resistance to downward movement of the auxiliary table section out of the plane iac section, and a horizontally and vertically 0scillatable auxiliary table top section, means to rotatably support said auxiliary top section upon an axis parallel to its longitudinal axis to enable said auxiliary top section to oscillate upon its said supporting axis, and means co-axial with said supporting axis to longitudinally adjust said auxiliary top section along its said supporting axis.

48. A treating table comprising a main table top section, a horizontally and vertically oscillatable auxiliary table top section, and a support common to both of said sections, said auxiliary top section bein rotatably mounted upon an axis longitu inally of said auxiliary top section, which axis in turn is supported and longitudinally adjustable upon a frame, which is pivotally supported upon a horizontal axis carried by said support, and located transversely of and at one end of said auxiliary top section.

In testimony whereof We have hereunto set our hands in presence of the subscribing witnesses.
