WILLIAM I. LERCH, OF HARTFORD, CONNECTICUT.
T 0 all whom it may concern Be it known that I, WILLIAM F. LERoH, a citizen of the United States, and a resident of Hartford, in the county of Hartford and State of Connecticut, haveinvented a new and Improved Swab, of which the following is a full, clear, and exact description.
This invention relates to improvements in swabs, and more particularly to devices of the character stated designed for use in connection with iodin or any'other liquid or fluid, or semi-fluid, an object of the inven tion being to provide a swab which will be entirely sanitary, which will permit the removal of the cotton after application, and which will result in a device which is en- 'tirely sanitary, and which most eflicien'tly performs the functions for which it is intended.
A further object is to provide a swab with improved means for holding absorbent cotton on the end thereof, and which preferably forms a portion of a bottle stopper so that by manipulating the stopper, the latter o erates as a'handle for the swab. I With these and other objects in view the invention consists in certain novel features of construction, and combinations and arrangements of parts, as will be more fully hereinafter described and pointed out in the claims.
In the accompanying drawings Figure 1 is a view mainly in vertical section, but partly in elevation illustrating my inventlon.
Fig. 2 is a view in elevation of my improved swab removed'from the bottle.
Figs. 3 and 4 are fragmentary "sectional elevations illustrating modifications.
1 represents a bottle or containgr having a liquid 2 therein which we may ssume to be iodin, although, of course, my invention is not limited to usein connection with any liquid or compound to be utilized.
3 represents the bottle stopper which may be of rubber, cork, or an other suitable material and to which a r0 4 is secured. This rod 4 is preferably of glass, although 1t may be made of any other suitable material and. is preferably secured in the stopper 3 by forcing the same into a recess 5 in the end of the stopper.
An enlargement 6 is provided on the lower end of the rod 4, andthis enlargement, shown in Fig. 2, is of, general spherical form. The enlargement 6 and the lower portlon of Specification of Letters Patent.

the rod 4 are made with a roughened surface 7 which may be conveniently formed by constructing the same of ground glass, although the roughened surface may be formed in other ways.
13 represents a ring which is movable on the rod 4, but which is of an internal diameter less than the external diameter of the enlargement 6 to prevent the accidental removal or loss of the ring.
In operation, absorbent cotton 8 is positioned around the enlargement 6 and the lower end of the rod 4 and the I ing- 13 is moved downwardly onto the cotton, clamp rod so that the cotton is securely held and forms a part of the swab.
In Figs. 3 and 4, I illustrate modified shapes of the lower end of the rod and a modified form of clamping device.
In Fig. 3, the enlargement 9, corresponding to enlargement 6, is of ellipsoidal form and the clampingdevice is in the form of a conical ring or cup-shaped collar 10 Wl'llCh has an extended bearing or gripping surface against the cotton 8.
In the modification shown in Fig. 4, the enlarged lower end 11 of the rod tapers gradually, or, in other words, decreases 1n diameter from its lower end to its point of juncture with the main portion of the rod 4, and in this modification I have shown a slightly different shape of'ring or collar 12.
It is, of course, to be understood that in some cases the cotton may be utilized in connection with theenlarged roughened end of the rod without the employment of any clamping device as the cotton will-gr p the rod, but, in most instances, I believe 1t advisable to employ a clamping ring or collar which will eflectually secure the cotton to the rod.
With my improved device, after each operation the cotton can be burned or otherwise disposed of and the lower end of'the rod and the ring can be sterilized before using again, so that the device can be main- Patented Aug. 30, 1921. i
tained'in absolutely sanitary condition at all rod as indicated in Fig. 2. When the swab is dipped into abottle withoutanyrotton around the enlargement, the r1ng W111 rest snug y against the enlargement and form a dipper or container for liquid. When the enlargement is moved over the surface to be treated, the ring will be slightly displaced, allowing the liquid to leak between the ring and the enlargement.
It is probable that the devices will be made comprising the stopper 3 and the elements of the swab and sold to the trade for use in connection with any sort of bottle or container, or may be so manufactured as to be used without regard to the particular container.
Various other slight changes might be made in the general form and arrangement of parts described without departing from the invention, and hence I do not limit myself to the precise details set forth, but con- 'sider myself at liberty to make such changes and alterations as fairly fall Within the spirit and scope of the appended claims.
I claim: 1. A swab, comprising a rod having an enlarged end adapted to receive absorbent cotton, and a ring movable on the rod and adapted to clamp said cotton on the rod, the internal diameter of the ring being greater than the external diameter of the rod but less than the external diameter of said enlargement. i
2. A swab comprising a rod, a handle on one end of the rod, an integral enlargement on the other end of the rod, a ring movable on the rod between the handle and the enlargement, the internal diameter of said ring being greater than the external diameter of said rod but less than the external diameter of said enlargement, and said enlargement tapering toward said rod and adapted to snuglyaccom modate the rin WILLIAM F.
