SPECIFICATION forming part of Letters Patent No. 404,019, dated May 28, 1889. Application filed November 24, 1888. Serial No. 291,756. (No model.)

To aZl whom it may concern:

Be it known that I, ALFRED W. SPERRY, of Hartford, Connecticut, have invented certain new and useful Improvements in Pessaries, of which the following is a specification.

The improvement relates to the class of stem-pessaries; and the object is to so construct a pessary of this class that it can be readily packed with a medicament for healing diseased portions of the organs for which they are intended; that can be used to support weakened organs; that can be easily placed in position to accomplish the above or removed therefrom; that is simple in construction, and that can be supported in position with the least amount of inconvenience to the patient.

Referring to the accompanying drawings, Figure 1 is a side view of the article. Fig. 2 is a similar View with a portion cut in central longitudinal section. Fig. 3 is a view of the under side of the base of the pessary proper. Fig. 4 is a side view of the same with an enlarged base, part being cut in central section to show the cup filled with an absorbent which is to be medicated. Fig. 5 is a plan view of the form illustrated in Fig. 4.

In the drawings, the letter a indicates the pessary proper, which is formed of gold, hard rubber, or any desirable non-corrosive substance, with a stem, 1), having an enlarged head rising from the center of a cup-shaped base, 0. The center of the under side of this base 0 is concaved oppositely to the cup of the base, and depending from the bottom of this lower concavity a distance less than the depth of the concave is a threaded stem, (Z.

To one end of the handle 6, which is preferably made of rubber, is fitted'a ferrule, f, the outer end of which is rounded, while the center is tapped with a thread that will easily engage the thread on the stem d. The end of this ferrule is of less diameter than the concaved portion of the under side of the base 0, and is so rounded that when any portion of the rounded end strikes the walls of the concavity the tendency of the end is to so slip toward the center that the stem d will set in the threaded socket, the upper edge of which is slightly beveled outwardly, while the stem, as before stated, is somewhat shorter than the depth of the concavity and has its outer end rounded to facilitate the coming together of the parts, so that a slight rotation of the handle will engage the threads and secure the parts together.

The outer edges of the cup-shaped base shown in Figs. 1, 2, and 3 are curved inward in order that no sharp edges may be formed, also to form a flange under which the medicament may be packed to prevent its removal from the cup.

If it is not desirable to make the cup of as great diameter as the diameter of the base, an annular disk, g, may be secured to the upper edges of the cup by solder or otherwise, the inner diameter of the disk being less than the diameter of the cup to hold the absorbent h which is to be medicated, while the outer diameter is long enough to allow the disk to support itself by pressure against the walls of the passage into which it is inserted.

In using the article, the stem d is screwed into the socket in the end of the handle 6, and the stem 1) introduced into the mouth of the organ it is to aid until the mouth closes over the enlarged head of the stem and holds the device in place. Then by turning the handle and disengaging the socket from the threaded stem the handle is free to be removed, leaving the pessary proper in place to perform its function.

In removing the article, the handle is introduced into the passage until the rounded end of the ferrule comes in contact with the concaved under surface of the base, which causes the end of the threaded stem to slip into the threaded socket in position to be e11- gaged by the rotation of the handle, so the device may be readily removed, when de-- sired, Without special inconvenience to the patient.

The device is simple, can be conveniently inserted or removed from place, and is adapted for the uses to which articles of this class are put.

I claim as my improvement- As a new article of manufacture, a pesengage the screw-threaded stein, substantially sary consisting of a stem with an enlarged as specified.

head risin from the center of a cup-shaped base, which has a concavity in its bottom, ALFRED SPERRY' 5 said concavity having a dependent screw- Witnesses:

threaded stem, and a handle with a rounded H. R. WILLIAMS,

end in which is a threaded socket adapted to F; H. CHAPMAN.
