PREVENTING CONCEPTION.

Specification of Letters Patent No. 4,729, dated August 28, 1846. l

To all whom t may concern Be it known that I, JOHN B. BEERs, of the city of Rochester, in the county of Monroe and State of New York, have invented a new Instrument, called the .wifes protector, t-he design of which is to Prevent conception; and I do hereby declare that the following is a full and exact description.

It consists Of six separate pieces, viz, hoop, band, joint, joint-pin, membranous covering, and handle.`

It is constructed in the following manner:

The hoop (A) is made of a piece of Oval wire, formed into a ring about an inch and a half in diameter, and tO this, is soldered the point (B), formed from a piece of hollow wire about l; an inch in length, which has two slots cut/in it (C, 0,) about pf an inch apart, handle (D, D,) which forms the other half of the hinge or joint. The center of this joint, from one slot to the other, is flattened at right angles with the hoop (A) to which it is attached.

The handle consists Of one piece Of metal, (gold alloyed with plat-ina is to be preferred on account of its great elasticity, and not. being liable to change color.) It should be about eight inches in length, and. about lg of an inch in width, except the end that lis crooked, which is left larger merely for Ornament. The other end is about vof an inch in width, and has two longitudinal slits extending of an inch from the end, and about fg of an inch from either edge, running parallel with the handle. The two outside planes are then formed into knuckles, tO work like a hinge in the slots (C, 0,) cut in the joint (B,). The center F is cut off even with the knuckles (D,4 D,) and is intended to rest upon the flat surface be tween the slots, and act as a spring, keeping the hoop while in use at right' angles. The two are then united, and kept in their place by a joint-pin. Thev hoop is then covered tO receive the end of tler.

with oil-silk, or some other thin membranous subst-ance (E,) and held in its place by a metallic band, made tO slip snugly over the hoop and t-hus securing the edges Of the covering between them. The edgesof the band are then to be burnished down smoothly; and lastly, the handle should be formed into shape, resembling the sectional" view in the annexed drawing No. 2.

To use this instrument, the hoop is tO be pressed down upon the handle by the thumb of the right hand, turning it up edgewise, and then introduced into thevagina, when, immediately after, having passed the sphincter, and the bo-es of thepelvis, it extends itself to its natLral/psition, nearly at right angles wit-h the rod or stem, and as it is farther introduced, the handle is to be turned downward l; of a circle. In this position-the membrane on the hoop is made to completely cover the Os uteri, thus entirely prevent-ing the semen from entering the uterus, without which, (it is assumed) conception can not take plael"l While the rod aforesaid lies along the lower side of the vagina, with a slight curve, to accommodate itself to the sphincter, and terminates in the angles above described, lying near the anus, and if properly adjusted, can not be felt by either party. After coition, when the instrument is being withdrawn the spring joint permits the extension of the hoop to nearly a parallel line with the rod accommodating itself to theshape and size Of the vagina, and bringing the semen away with it.

What I claim as my invention, is-the particular combination of a covered hoop attached to a handle by a spring-joint as described and for the purposes above specified.
