T0 00% whom it may concern:

Be it known that I, EDWARD J. NoBLETT, of Chicago, in the county of Cook and State of Illinois, have invented a new, useful, and Improved Physicians Gynecological Folding Tall-Table, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in which like letters of reference in the different figures indicate like parts.

The object of my invention is to provide a gynecological table for physicians which may be folded against a wall when not in use, compact, simple, strong and durable and adapted to be placed in the varying positions or inclines required by physicians in the class of work for which said table is intended; all of which is hereinafter more particularly described and claimed.

Referring to the drawings, a, Figs. 1 to 4 inclusive, represents a frame or backing which is rigidly bolted or otherwise attached to the wall of the building in which the table is intended to be placed. Rigidly attached to the back a, are plates b, Figs. 1, 7, 8 and 9, upon which are cast or otherwise formed sockets h, for the reception of balls 0' Fig. 8, upon the ends of rods 0 c, which are not only adapted to rotate in said sockets, but to swing obliquely therein as'clearly indicated in Figs. 1, and 8. The rods '0 are loosely journaled in hearings in a rectangular metal frame cl, preferably made of SteeL-shoulders d, rigidly attached to said rods, being provided to aid in retaining said frame in proper position upon said rods. Loosely attached to the rods 0 near their outer ends, are sleeves e e, Figs. 2, 3, 6, and 7, having lugs e a, thereon, to which are hinged braces f f, which are jointed at f in order that they may be folded, as hereinafter stated. The lower ends of the braces fare provided with cross Ts f f Figs. 25 and 27, and said lower ends are loosely inserted in slots 9 of plates g g, Figs. 1, 2, 3, 4, 25 and 28, which are rigidly attached to the back Ct, at or near its base. Blocks g (see Fig. 25), are loosely pivoted one above another in the case 9, and are provided with sockets or notches at the top, as shown for the reception and support of the cross-T Said blocks, by virtue of their own gravity, rest normally in the position shown in Fig. 25, but are free to swing back, as indicated in dotted lines to permit the cross-bar f to pass upwardly and engage with whichever one it maybe permitted to rest upon. Upon the side of the plate 9, is a loose plate h, Figs. 1, 2, 3, 26 and 28, which is provided with pins h arranged to project loosely through slots g and engage with the gravity blocks 9 A rod 2', attached to a lug upon the plate 71., is extended upwardly and arranged to connect with a bolt i, which is loosely adj usted within a suitable plate 6 attached to the back a, better shown in Figs. 1, 24: and 29. A thumb-piece 1' enables the bolt to be actuated, while a spring '5", Fig. 24, serves to retain the bolt in a given position. \Vh'en the thumb-piece t is in the position indicated in Fig. 24, the gravity blocks g, are free to remain in the position shown in Fig. 25, or to be thrown back temporarily to permit the part f to be moved upwardly past them. Upon raising saidthumb-piece the pins h are caused to press against said blocks and hold them back;-thus enabling the part f to move downwardly past them to the bottom of the plate g, for the purpose hereinafter stated.

It should be understood that the stirrups are made somewhat wider than the length of the part f ,so that the pins h may press against the edges thereof and move them back when desired, while the part f is free to pass up and down without being brought into contact with said pins.

The frame (Z, is braced laterally by means of the angular braces (Z and the central cross bar (1 Figs. 5 and 6, which are riveted thereto in the manner indicated.

. Superimposed above the frame d is a supplemental framej, of metal, within which is rigidly secured a wooden frame j, preferably provided with a cross-bar j Fig. 5. The wooden frame j serves as a means for attaching the cover 3' which is preferably made of cane or rattan. l intles j, Figs. 5, 6 and 19, upon the frame j are arranged to engage with sockets (1 in the frame cl, thereby retaining said supplemental frame firmly in place, while one or the other end is free to be raised from the main frame without causing lateral or endwise displacement. Rigidly attached to the rods 0 0 respectively within the frame (Z- near its front, and parallel therewith, are lever arms 70, Figs. 1, 2, 3, 6, 7 and 15, having handles as shown,the short arms R of said levers, being loosely connected to links Z, which are in turn pivoted to the frame j. Crank arms corresponding to the short arms 70 are also rigidly attached to the rods 0 a near the rear of the frame d,see Figs. 3, 5 and 6,-and are, in turn, connected with links Z which perform the same office as the links Z said links or their connections, form- 7 ing kneeor toggle-joints, which may be manipulated by means of the lever-arms k, which enables the frame j to be raised to any desired extent, within given limits. One end only may be elevated, as shownin Fig. 1, or the entire upper-frame may be lifted, as shown in Fig. 5. In order that said supplemental frame may be adjustably secured in position when raiscd,l prefer to employ the following described locking device: Cog-wheelsm, Figs. 6, 7 and 15, are rigidly attached to the rods 0, adjacent to the frame d. Pivoted to the frame d at m, are tongs m m which are provided with detents m respectively, adapted to engage with the cogs of the wheel m. The arms of said tongs are bent in opposite directions, and are provided with slots 012 through which is inserted a pin m, which rests and is adapted to slide loosely in a slot in the frame (Z. shown in Fig. 16. A thumb-piece m, Figs. 6,and 16, upon a sliding plate is rigidly attached to the pin m and enables said pin to be reciprocated. hen the pin on is in the position shown in Fig. 15, the cog-wheel m is locked and with it the rod 0 to which it is attached; but a re-' versal of the thumb piece, enables said rods to be freely rotated by means of thelevers 7a. The rods 0 are of sufficient length to enable the table to be placed about six inches from the back a which space is utilized for the reception of an instrument box n, provided with a hinged lid a, space being left to allow the table to be lowered pastsaid box so as to hang beneath it when not in use.

Resting loosely in stirrups j, Figs. 5, IO, 19 and 20, attached to one end of the framej, are bars 0 0, provided respectively with notches 0' 0. upon the under side thereof for the purf pose hereinafter set forth. Stirrups 19,19, Figs. 1, 13 and 14, are adapted to be detachably secured to the projecting ends of. said bars by means of cams p p. The bars 0 0, which are preferably about the length of the main frame j are passed loosely through openings in sliding plates q, q, Figs. 10, 11 and 12, which are in turn loosely fitted upon curved plates q rigidly attached to the bottom of. the wooden frame j and oross-piecej The plates q (1 may be moved laterally in the arc of a circle, so that the bars 0 may be parallel more or less oblique to each other for the purpose of regulatiugthe distance between the stirrups p p. The plates q may be locked at any desired point, and the bars 0 rigidly secured therein by means of cams g g Perforated lugs r0", Figs. 1, 5, 10, 17 and III.)

18, integral with the frame j are extended from the respective ends thereof to serve as points of attachment for head and foot rests s and t, respectively, which are provided with corresponding extension lugs s s and t t. A springt is attached to each of said last named lugs in the manner clearly indicated in Figs. 17 and 18, said spring being provided with a laterally projecting stud i which projects through a bore in the lug to which said spring may be attached, and is sufficiently long to project into the bore of the lug 7', thereby forming a hinge. A laterally projecting stud 25 rigidly attached to .the spring tienables.

the latter to be bent and the head or foot'rest may, by means thereof be readilyattached to or detached from the frame j. A curved brace u, is hinged to a swivel a, loosely attached to a lug u rigidly secured to the frame dat the respective ends thereof, as shown in Figs. 1, 2, 3,4, 5, -6, and 21. The free end of each of the bars u is provided with a bore a Fig. 1. The ends of said bars u are intended to be connected respectively with locks 12, Figs. 5,

22, and 23, arranged to slide upon bars to,

which are arranged lengthwise of the headrest 8, and foot-rest t respectively. The bars to are provided with notches to, which are engaged by a pawl 11 actuated by a spring 0 Fig. 22. A pin 22 which is retained in a normal position by means of a spiral spring 71 Fig. 23, is adapted to engage with the bore u in the end of the bar it, thereby enabling the head and foot-rests to be adjusted to any incline as indicated in Fig. 5, or the braces u may be detached at will by withdrawing the pins 11 Having thus described the various parts of' my improved device, I will now briefly explain its operation.

Assumingthe table to be folded against the wall in the position shown in Fig. 4, the front of the frame d is grasped by the operator and raised to a horizontal position as shown in Fig. 2. The head and 'foot rests may then be adjusted to any desired angle by means of the braces to and locks 11, or one or both rests may be removed to suit the requirements of the operator. If it is desired to incline the table laterally, it may be accomplished by merely raising the front when the lower ends of the braces f will be automatically engaged and held by the blocks 9 If necessary to again lower said table to a horizontal position it may be'done by lifting the braces out of the stirrups and raising the thumb-pieces 2' when the blocks 9 will be held back and the foot-pieces of the braces are free to pass down to the bottom of the plate g, without engagingtherewith. One or the other end of the supplementary frame j may be raised by tilting the frame j by means of one or the other of the levers 70. Or the position known as the Sims position may be secured by first tilting the main framelaterally, as described and then tilting the supplemental frame 1on gitudinally. This serves to raise one of the.

outer corners of the table higher than the others.

When necessary to use the foot stirrups p,

the leaft is removed, the bars 0 extended as notches o, inthe bars 0 prevent them from slipping and enable them to be readily adj u'sted.

The advantages of my improved device are that it may be compactly folded when not in use, While it enables every desired position or incline to be obtained with ease, rapidity and certainty.

Having thus described my invention, I claim 1. In a physicians gynecological table the combination of the frame permanently hinged at one edge to a all or other support and adj ustable braces supporting the outer or free edge whereby said frame may be tilted laterally and a supplemental frame superimposed above the first and means for independently elevating either end of the supplemental frame above the main frame whilethe opposite end of the supplemental frame rests on the main frame, substantially as described.

2. In a physicians gynecological table the combination of a main frame hinged at one edge to a wall or other support, the outer edge' of the said frame being supported by diagonal braces the lower ends of said braces bearing upon the support to which the frame is hinged, said braces being adjustable Vertically thereon, a supplemental frame superimposed above the main frame and engaged thereto at each end by toggle joints, and a crank at each end of the main frame engaged to saidtoggle joints, each crank adapted to operate and elevate its respective end independently of the opposite end, substantially as described.

3. In a physicians gynecological table the combination with a frame pivoted to the wall or other vertical support, of diagonal braces for supporting the outer edge of said table said braces pivoted to the table and extending down to the vertical support, pivoted blocks on said support in which the lower ends of the braces rest and means for throwing said blocks to the position where they cannot be engaged by the braces, substantially as described.

4. In a table of the class described the combination with the frame having its edge supported by braces, the lower ends of which rest in pivoted blocks, of means for holding said blocks out of operative position, consisting of a vertically movable rod adapted to engage and tilt each one of the stirrups, substantially as described.

5. The combination in a table of the class described, of a main frame mounted upon rotating rods secured to a wall or equivalent vertical support by means of universal joints,

oblique lateral folding braces in operative connection with said supporting rods and the base of said vertical support, means for adjusting the height of the basal support of said braces, a supplemental frame superimposed upon said main frame and connected with said rotating rods by means of knee or toggle-joints, means for independently rotating said revoluble rods, and means for temporarily locking the same in a given position, whereby said table may be folded and unfolded and said main and supplemental frames may be tilted and maintained in planes oblique to each other, substantially as shown and described.

6. The combination with the main and supplemental frames dj, of the rotating hinged rods 0 0, adjustable braces ff, knee-joints connecting said frame j and rod 0, cranks for tilting said knee-joints, and locking devices for securing the same in position, substantially as shown and described.

7. The combination with a gynecological table, of the stirrup supporting bars 0 0, means for adjusting the same longitudinally, and

movable locking devices arranged to swing together with the bar in, the are of a circle beneath said table, whereby said bars may be moved longitudinally and obliquely to each other, substantially as shown and described.

8. The combination with the longitudinally movable stirrup supporting bars o-o-hinged beneath the table and adjacent to the edge thereof, of locking devices on inner end portion of said bars arranged to swing with the bar in the arc of a circle, whereby the outer end may be adjusted horizontally, substantially as described.

9. The combination of the bars 00- the stirrups through which the bars are passed, the plates (1, q, and the curved plates q all arranged, substantially as described.

In testimony whereof I have signed this specification, in the presence of two subscribing witnesses, this 14th day of January, 1892.
