.Fig. 4 is a plan the bed with the head after referred to.
The frame supports a horizontal body-supporting top which the patient may lie stretched out, or in any other comfortable position, prior to delivery.
According to the present invention, the bodyform two sections-a section l9, at the head-end of the bed, will hereinafter be termed the head section, and a. section 20, which, because it is at the foot of the bed, will hereinafter section.

7 provided with wheels 26 riding have flanges to hold them from levers 33 or pad 24, the latter fitting within a peripheral flange 25. Of course, it should be understood that any suitable form of construction may be employed. 7
The head section I!) is preferably of such length that when the patient lies stretched out on the top portion, the body of the patient from and including the buttocks upward toward the head is supported on the section l9, while the lower limbs are supported on the foot sectionZEl, andit is inthis position that the patient lies awaiting the time for delivery. When this time comes, according to the present invention in its preferred form, the 7 section H) with the patient lying thereon is moved toward the foot of the bed so that the physician may have easy and convenient access to the padelivery directly from the'foot of tient during the bed rather than from over the side of the By so moving the section I9 to the foot of the bed, the patient is brought into the most desirable position, whether for natural delivery or for delivery aided by instrumentsywithout disturbing the position of the patient on the section l9.
For this purpose, the section I9 is slidably mounted on the top rails l0, and preferably is on the top rails.
The wheels may shifting away from the rails.
Since the sections I9 and 20 are normally located in the same horizontal plane and are coextensive with each other, one of these sections must be movable vertically relative to the other to permit the heard section'l9 to reach the foot of the bed. Many difierent arrangements for accomplishing this may be made; but, in the form of the'invention at present preferred, the foot section 23 is so mounted on the frame that it may be moved belowits normal horizontal plane and permit the section l9 to travel over and become superposed over it. Accordingly, as shown, the section 23 has brackets Zl secured to the frame 25 and the brackets 23 which ride on vertical rods 29 carried in brackets 39 on the top rail ill bottom rail l3. To counterbalance the weight of the section 23 and the portion of the patients bodyresting thereon so as to hold the'section 29 upward movement with the upper collars 28 engaging the brackets 39 on the top rail it, each rod 29 is provided with a compression spring 3! bearing at its lower end on the lower bracket 33, and at its upper end onthe lower With this arrangement, to move tion as out of the 'way so that the section l9 may advance toward the foot of the bed, it ismerely necessary to depress the section 29 below the lower edge of the frame 2! of the section l9. 4
This may be done in any suitable way, but, in the form of the invention hereindisclosed, it is accomplished by connecting to the center of the frame 2! of the section 23 a pull rod 3 2"which has its lower end pivo-tallyconnected to a lever 33 fulcrumed at g V cured to the lower rail I3. fIhe pivot-ends of the are spread apart andthe free ends are brought together at the foot-end of the bed where they are connected to a treadle be engaged by the foot of the physician or his assistant; When the treadle is pushed down, the pull rod 32 is also drawn down and the section 20 of the bed is depressed.
1 In some instances, it is desired to lock the section 23 depressed until such timeas itis again the foot sec-,
34 on brackets 35 which are ,se-
36 in position to needed, and for this I) 'pose a toggle lock shown in the accompanying drawings may be employed.
This toggle lock comprises a pair of links 31 having their upperv ends connected to al bracket on, the end rail l5 and g and between the links 31, and at 40 to the lever 33. When the treadle 36 is depressed, the links 31 and 38 move from the position'shown in fulllines in Fig. 'l to the position shown in dotted lines, in'whioh the center 39 is carried beyond a line-drawn through the pivot points of the links v 31 and 38, and the link 31, striking against the lower end rail it, prevents the toggle from closing in the opposite direction and holds the section 20 depressed against the tension of the springs 3|. V Ordinarily, the weight of the patient on the section l9 when the latter is over the section 20 is sufficient to hold the section 20 depressed. Moreover, the section 19, being provided with guard 20 fingers 40 (see Figs. 3 and 6) which ride under the upper webs of the top rails Illjis held tojthe top rails and would prevent the section 19 from being lifted off the rails by the section 20.
However, by having the section by the foot of the. physician and locked in depressed position, the operation of moving the section 13 and the patienttoward the foot of the its further movement is limited by guards 4| on 4o the rails l0 engaging the wheels 26. The section 20 is then permitted to rise so as to be coextensive with the section l9..
Anesthetists usually prefer to work from the head of the bed directly over rather than over the side of the bed, and,,in order that this may be done in cases where anesthetics are necessary, the space between the side rails l0 and I3 at the head of t e bed is left open and un-' obstructed. If anesthetics are to be given the 50 patient before being moved to delivery position, the anesthetist may commence to work while the bed is in extended position shown in Figs. 6 and '7, and may follow with the patient tothe operating position shown in even assist in advancing thesection or operating position. e 7

In order that the stirrup armsf42 may be out of the wayand unobtrusive when not in usejthey are pivotally mounted on pins frame 2| of the section l9. The pins 44 are inclined with respect to the side flanges 25 ofthe frame 2| so that when they are swungbackwardly they will clear'the side flanges, while when they are swung toward the foot of the bed they will 75 a link 38 connected at 39 to 5 20 depressed 25 i the patients head 45- Figs. 4; and 5, and may 55 stirrups 43 to receive the patients i r 44 secured to the move-in slightly into the desired position. The stirrups 43 are located in operative position quite far apart so as to cause the patients legs to be such that the patients legs are in flexed position When the feet are located in the stirrups.

In order to adjust the stirrups so that the legs may be held higher or lower as desired by the physician, each plate 56 is provided with an adsecured to the section I9, they may be employed by the patient during labor if desired.
To further aid the patient and hold the patient in position on the section I9, the latter may be provided with shoulder braces. These, in the form shown, comprise shoulder pieces 55 carried tient, and, for this purpose, each is mounted on a rod 59 carried in brackets 50 secured to the adjacent side flange of the frame H. is held in longitudinal ad usted position by a handscrew 58a.
The movement of the section I9 toward the foot of the bed may be limited by stops 6| engaging the wheels 25 at the bottom end of the section I9.
The legs I I may be provided with Wheels or casters 62 so that the bed may be moved from place to place.
Variations and modifications may be made within the scope of this invention and portions of the improvements may be used Without others.
