GEORGE E. I-IUTCI'IINGS, OF GALVESTON, TEXAS.

DROPPER FOR MEDICINES.

SPECIFICATION forming part of Letters Patent No. 718,764, dated January 20, 1903.

Application filed April 23, 1902. Serial No. 104,358. (No model.)

To all whom it may concern:

Be it known that I, GEORGE E. HUTCHINGS, a citizen of the United States, residing at Galveston, Texas, have invented certain new and useful Improvements in Droppers' for Medicines, of which the following is a specification.

Myinvention is a dropper for medicines and other liquids and is adapted for use with any ordinary form of bottle or like receptacle, to which it may be readily applied for the use intended. I aim to produce the article complete and of very simple construction, capable of being readily cleansed, and effective and regular in its operation. It is essential that articles of this class be made very cheap in view of their extensive use, and it has been my purpose to provide a construction capa-.

ble of being made simply and economically and preferably out of glass, as this minimizes the danger of contamination and enables the user to be assured of the cleanliness of the article.

In the accompanying drawings I have shown in Figure 1 a sectional view of the bottle having my improved dropper held in place within the neck and being shown as in operation, the bottle being inclined to allow its liquid contents to drop out in the manner indicated. Fig. 2 is a section taken vertically through the dropper as it is shown in Fig. 1. Fig. 3 is a plan view of the dropper as shown in Fig. 1, and Fig. i is an end view.

The bottle A may represent any formof receptacle to which the dropper may be attached or with which it may be used. The dropper is shown at B and has a tapering end 0 terminating in an open end, this tapering end being fitted to the neck of the bottle and being made sufficiently tapering so as to adapt it for use in connection with the various sizes of bottles as ordinarily used. At substantially right angles to the tapering base I form a projection D, terminating in a pointed end with rounded inner and outer Walls and provided with a perforation E,extending through from the interior to the exterior. This perforation is preferably tapering, being largest where it penetrates to the interior and tapering to the exterior, where it is of least size. As the bottle is tilted to the position shown in Fig. 1 the liquid fills the interior of the dropper and the drops issue through the perforation or orifice E with regularity and of uniform size and weight. This is very important in the dropping of medicines and gives a very great advantage over the forms of droppers where positive pressure is employed and consequent irregularity and lack of uniformity follows. In order to equalize the air-pressure, I form a vent or opening F in the rear wall of the dropper in line with the discharging-orifice. This opening F also provides access to the interior of the dropper forthe ready cleansing thereof.

What I claim is- As a new article of manufacture, a dropper for liquids in one piece comprisingan openended tapering portion adapted for connection with varying sizes of bottle-necks, and an angular extension thereof having a closed wall in line with the open-ended part, an orifioe through the end of said extension and a vent immediately in line with the droppingorifice, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE B. HUTCHINGS.
