To all whom it may con Be it known that TRINCA, a subject Britain, residing at Gaulfield, in the I, FRANCIS LOUIS of the King of Great 96 Balaclava Road,

in the course of evolution, ture from the four-footed to change of posthe erect attitude has greatly interfered with the process of child-birth. In four footed animals, the

animal delivers itself on knees. In th1s manner expel the offspring, oper all fours, or on its the muscles, which ate agalnst the purchase of a rigid vertebral column, and also gravity. When a patient lies on a bed, th1s mechanical advantage is lost. During childbirth, the usual aids extended are allowing the mother to pull on a towel attached to the head of the bed, or pressure is applied by hand to the lumbo-sacral region. Each at restoring the rigid ve aims rtebral column, and

so restoring the requirements of evolution.

The pressure applied greatest benefit, but is too operator to be contlnued time.

The object of the provide an appliance pressure can be applied self to her lumbo-sacral recurring labour pain.

Figure Figure Figure portion of the appliance ure 1) in engagement 2 is a front elevation thereof; 3 is a back elevation thereof; 4 is a side elevation of the lower (illustrated in Figwith the left-hand angle iron (shown in section) of an iron bedstead;

Figure 5 is a front elevation of Figure 4:;

Figure 6 is a side elevation of the lower portion of the appliance (illustrated in Figure 1) in engagement with a short length of angle iron (shown in section) aflixed to portion of the appliance ure 1) in engagement wi (illustrated in Figth a short length of angle iron (shown in section) affixed to the left-hand siderail of a wooden bedstead;

1 is a vertical bar of'spring steel, the lower end of which is re-curved to constitute a U-shaped recess 2 to receive or engage either with the vertical portion 3 of the left-hand angle iron of an iron bedstead, or with the vertical portion 4 of a short length of angle iron afiiXed either to the left-hand rail of a wooden bedstead or to thesame rail of a round frame hospital bedstead. By lefthand angle iron or left-hand rail is meant thatangle iron or rail which is on the left of an observer standing at thefoot of the bedstead. 5 is a threaded bolt inserted in a slot provided in the bar and in turn fitted with a butterfly nut 6 by operating which the vertical bar is held firmly to the vertical portion 3 of the angle iron of an iron bed- 7 is a short vertical slot in said said slot being situated imthe recess 2 8 is a'threaded bolt which passes through'said slot 7 Said bolt is provided with a hook 9- at one end, to engage with the horizontal portion '10 of the angle iron.' 11 is a butterfly nut at the other end'of bolt 8, by operating which the necessary adjustment and attachment of the appliance to the bedstead can be effected. 12

stead. vertical bar 1, inediately above is. a long vertical slot in the said vertical bar 1. 13'is the vertical portion of an L-shaped metal bracket. 1a is a T-piece at the upper end of said vertical portion, the

ends 15 of said T-piece being bent to engage with the respective edges of the said vertical bar 1, so as to permit of said bracket sliding freely up and down on said vertical bar. 16 is a threaded bolt which passes through the vertical portion 13 of said L-shaped bracket, and also through the said long vertical slot 12. 17 is a butterfly nut on the end of said bolt 16, by operating which the L-shaped bracket can be raised or-lowered, as may be required. .18 is the horizontal portion of ,said L-shaped bracket which at its outer end is attached by means of a ball and socket joint-19 to an oval-shaped metal plate 20, to the front'of which is attached, in any approved manner, a pad 21 of sponge rubber. 22 are two pins which project outwardly from what constitutes the back of the vertical bar 1. 23 is a strap of webbing having a loop which said buckle can engage, if required, so as to constitute a loop at the end of the strap. 27 is a short length of angle-iron which I use when it is desired to attach my appliance to a wooden bedstead, or a round frame hospital bedstead. This short length of angle iron 27 is affixed to the left-hand side rail of the bedstead, as illustrated in Figure 7, by means of bolts 28 which pass through holes 29 in the said side rail, any side slip being prevented by the slot 30 With which the Ushaped recess 2 engages.

N hen my appliance is attached to a bedstead, the patient lies on her left side with the pad 2l aga-inst her lumbo-sacral region. The strap 23, one end of which, as before explained, is attached to the top of the flexible steel bar 1, is then passed between her right arm and body, and the free end of the strap is grasped by her with both hands. At each recurring labour pain, she pulls on the strap 23, thus causing the upper end 0f the flexible steel bar 1 to yield. In lieu of pulling on the end of the strap 23, the. said end may be formed into a loop, by causing the end of the strapto engage with the buckle 25, and the right armof the patient passed theret-hrough, thereby perinitting of greater-traction on the vertical bar l. The result, in either case, is that the necessary pressure is exerted on the lumbosacral region. The use of my appliance results: in greatly decreased pains, as felt by the patient: reflex *quickening and increased etiicie-ncy ofthe pains expelling the foetus; and diminution of the final exhaustion of the patient and its dangers. There is also a probable increase in size of the bony outlet, due to rotation of the iliac bones around the ileo-sacral synchondroses allowed by a bending of the symphysis pubes.

I claim 1. An appliance of the character described comprising a vertically mounted bar mounted in the slot in the bar. for releas ably clamping the bar in various positions of vertical adjustment on the bar, a padded pressure applying member universally connected to the bracket, and a iiexible pulling member attached to the upper end of the bar for transmitting pressure to the pressure applying member.

An appliance of the character describedcomprising a vertical bar of spring 36681 the lower end or" which is curved to provide a U-shaped recess while the portion immediately above the recess is provided with a vertical slot, a hook like clamping bolt adjustably mounted in the slot, a clamping element mounted on the bolt, the vertical bar being also provided with another vertical slot in the upper portion thereof, an L-shaped bracket the top of the vertical portion of which engages With the vertical bar and is adapted to slide vertically thereon, a metal plate universally connected to the end of the horizontal portion of the bracket, a pad connected to the outer side of said plate, a nut and bolt arrangement engaged by the bracket and upper slot for holding the bracket in various positions of vertical adjustment, and a flexible pulling member attached to the ver? tical bar, substantially as and for the purposes set forth.
