To @ZZ whom it may con/cern.:l

Be it known that I, LYMAN G. BARTON, of Willsborough, in the county of Essex and State of New York, have invented a new and- Improved Surgeons Portable Posturing-Table, of which the following is a f iill,elear, and

exact description.

My invention relates to improvements in that class ofV tables which are used by surgeonsin performing surgical operations; and the object of my invention is to produce-a comparatively simpletable having leaves at` opposite end s for the head and feet, Wh-ich are movableindependently of each other; to provide means for changingtlie angle of the g table as a whole without altering the angle ofthe head and foot leaves in relation to the middle section of the table; to provide vari'- ons attachments which may be conveniently applied to the table and utilized for different purposes in holding the limbs of a patient; to prov1de a table having its'parts readily separable; to arrange the parts so that they are very light and strong; tolprovide an easy means of adjusting the leav'es to any neces-l sary angle, and toprodnce a table which may be easily taken apart and folded into a very small com pass.-

" To these ends my tain features of construction and combinations of parts, which Will be hereinafter de scribed and claimed.

' Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a broken invertedI plan view of the table-top and theleaves thereon. Fig. 2 is a broken side elevation of the table with the head-leaf raised and the foot-leaf lowered. Fig. B is a detail perspective view of'one of the locking-clips which are adapted to be secured at variouspoints on the table to assist 1n holding various attachments to be hereinafter described. Fig. 4.is a longitudinal vertical section on the table onthe line 4 4 of Fig. 6, showing oneof the leg-rests in position the line 6 6 of Fig. 4. Fig. 7 is a perspective `view ofthe table with the body of the table 'invention consists of cer' shelves .which may be applied tlereto to siipport an armor a leg. IFig. 9is a broken detail perspective view showing-the way in which the shelf is attached to the table top. Fig. 10 is a detail sectional view showing how one` of the curved braces is attached to the tabletop. Fig. 11 is a detail perspective view of one of the foot-rests. Fig. 12 is an inverted plan view of the preferred form of tabletop frame, and Fig. 13 is a cross-section on the line 13 13 of Fig. 12.

The table top 10 is provided near the centei and on opposite sides with depending forked cli-ps 11 which are adapted to rest on the pintles 12 of the table legs 13'and thus form a pivotal support -which permits the table to be swung easily up and down and conveniently removed from the legs.

' The' legs 13 are preferably angular in cross section, in order that they may be light and strong and they are hinged together at the top as specified, the legs on'A opposite sides of the table being connected at thetop by cross bracesla and near the bottom by-braces 14 so as to give themthe necessary strength, while at the bottom the-longitudinally opposite legs are connected by'braces 15 which are pivoted to the legs, are` pivoted together, as shown at 16 in Figs. l and 4, and are provided with overlapping ends and with a clip 17 fastened to one brace and adapted to engage the top edge ofthe other so as to prevent the brace from swinging below a horizontal position.

This arrangement just. described enables the legs to be folded together wliendesired.

lThe table top is slotted transversely in the center, as shown at 18, and beneath the centero f thel table is a removableshelf 1,9 which rests on brackets 20 ksecured to the legs 1.3, see Fig. 4, and on -this shelf a vessel may be placed to catch the drip from the table. fThe table top' is held in place 'and is braced by the curved braces 2 1, which are arranged on opposite'sides of it, the braces terminating at their ends in hooks '2la which are adapted to'engage pins 21b on the-under side of the table, as shown in Figs. 1, 2 and 1Q, and these braces turn in clips 22 on the table legs and are held in a fixed poa i Y 540,939

sition by set screws 23, seeFigs. 4 and 6, which projectthrough thelegs and mping'e on the braces. Y v

lThe clips 22 serve to guide the braces and also support them, and it willbe seen that the table may beswung steadily and accurately on its pivot when the screws 23 are loosened and, by tightening the screws, the table may be held at any desired inclination. The table top has at -its ends leaves 24 and 25, the for mer being at the head of the table and the latter at .the foot, and the leaves are hinged to.

the table top, as' shown at 26, and they may thus be heldat any necessary angle to the table top. The leaf 24 has on opposite sides con'-4 verging arms27 aud 2 8, which are held in

recesses

29 and 30 in the side edges of theleaf, and the lower ends of these arms are pivoted to braces 31 arranged on opposite sides of the table and moving in guide clips 32 on the braces 21 in which cli-ps they are fastened by set screws 33, see Figs. 4 and 7, and in this way the table leaf 24 may be held in the desired position and may be instantly released and its position changed." The leaf is provided wthbraces 34 which are pivoted inre-4 being fastened by set screws 37 and thus thel 3 which is shown in detail in Fig. 3.

cesses 35 in opposite edges of the leaf and which are -held in clips 36 on the braces 21,

angle of the leaf in relation to the table top' .may be easily regulated. The table top, when of wood, and' the foot leaf 25 have,'in theirA underside, transverse recessesd 38 which are covered by plates 39 having at necessary intervals keyhole slots 40 therein which are adapted to receive the locking clips 41, one of The clip 4l has a spindle 42 with a bit 43at one end,

which is adapted to tit in one of the key-hole slots 40 and which, when turned ont of registry with the slot is held above'the plate 39, thus locking the clip iu place. The clip has a bearing washer44 which-lits against the plate 39, a collar 45whose bore is at right angles to the spindle 42 and which is adapted' tol receive one of the rods hereinafter described, and with a set screw 46 which projects through the collar and is adapted to impinge on a rod to ffasten it in place.

The table top is, near thefoot leaf, provided with vertical holes 47 and the foot leaf is also near its hinged end provided with similar holes, the holes, when the table top is of wood, being preferably bound by wear plates 4 8, although this is not essential. The purpose of these holes and the locking clips is illustrated in 'g. 2, in which the foot leaf. 25 is swung down at substantially right angles to the table 'top 10, while the leaf 24 is raised to form a support for the head.

'lhe locking clips 41 are fastened, in the manner heretofore described, on the under side of the table top so\as to align w'ith one of the holes 47 in the leaf 25, and a rod 48 is thrust through' this hole and the collars 4 5 of the two locking clips to whichit is fastened by the set screws 46,.while the foot rest 49 is attached to the projecting end of the rod, this inserted in the clips and fastened as described,

tbe rod being also extended' through one of 'the holes 47 in the table top and an extension 54 of the rod is connected with it bya nut 55, while thel upper end of the extension is arranged to carry the leg rest- 56 which has a U-shaped center frame 57 with a fixed nut 5 8 on the underside to screw to the 'rod 54. This leg rest has also parallel side bars 59 arranged at right angles to the frame 57 and, held in collars 60' at the top of the frame to which the side barsar fastened by set screws 61,. These side bars have slots 61* to receive the ends 62 of the leg straps 63,'which straps are provided with suitable buckles and have other straps 64 to be fastened around the limbof a patient.

It 'will thus be seen-that the leg may be securely held in the leg` rest while a patient lies height of the leg rest lmaybe easily regulated and that the leg rest may be adjusted verti-` cally, so as to support the desired part of the 4ou the table, and it will be observed that the leg, and horizontally by means of the-l parallel bars 5 9.

It is apparent that when the leg rest is in v.the position shown inFi'g. 4, it is applied to to the leg below the. knee, constituting what is @known as the lithotomy position; but

when it is applied for Trendelenbergs positiem, the rod 53 or 48 is adjusted as shown in. Figs. 2 and 7, so as to project through the leaf 25, and the leg rest'is fastened to the end of the rod as specified. 1t will of course be u'nderstood that two leg rests may be arranged lside by side, either 4on the top of the table or on the leaf, as shown in Fig. 7, and they may be held near thecepter or nearer one side of the table as desired, and may be adjusted horizontally or vertically by. means of the rds 453 and the parallel bars 59.

In connection with the table, a. 4side leaf 65 is used, see Figs. 8 and 9,-which may be ar ranged opposite either end oftheI table soas tosnpport an arm or leg. The shelf 65 has on the under side key-hole slots 40,/like those already described, to receive the retaining clips 41,'an`d rods 66 are fastened in these clips and extend beneath the -table where they are fastened by similar clips, as already described, and thus the shelf is' held at right IIO angles tothe table top and mayfbe adjusted l in and out as desired. 4,

-Froin the foregoing description, it will be seen that the limbs of the patient may be se- 6o braces having their ends detachably securedV eurely held, that the table may be adjusted is provided for catching all the drip fromthe table, and that if the table is not in use it may be taken apart and vfolded snugly up.

' The table top, as above described, is made in any convenient way, but it is sometimes necessary to have the top of metal, sometimes of wood, sometimes of glass, or other things maybe used. ATo provide for easy variations or modifications, the table top is'.

preferably provided with a rectangular binding frame 66a`of angle iron, this frame having central crosspieces 67 which have sufficient space between them to form the transrlhe plates 68 have'also fastened totheir under sides, at necessary points, cross plates 70 verse slot in the table top above referred to, and the frame is provided with longitudinal plates 68 which are arranged at necessary intervals and extend from theI ends of the frame to the c ross pieces 67 so as to support slabs 69 of wood, glass, or metal -which are laid on them to form -the top surface of the table.

which are provided with key-hole slots 40 like those already referred to. It will be seen that this frame may be fastened to the supporting legs in the manner 'already described.
