ERNEST C. TROWBRIDG'E, 0F GLOUCESTER, MASSACHUSETTS.

MEDiCINE-DISPENSER.

To all whom it may concern:

Be-it known that I, ERNEST C. TROW- \BRIDGE, a citizen of the United States,"-residing at Gloucester, in the county of "Essex and State of Massachusetts, have invented new and useful Improvements in Medicine- Dispensers, of which the following is a specification.

. Tl'lixiIiVGIltiOIl relates to an improved droppen for collod'on, iodin or any other medicated solution or external or internal use, the object of the invention being to provide a dropper which constitutes a stopper for a bottle-and which can be used to '"measure the medicated solution drop by drop, and which can be used either for measuring a certain number of drops of the medicated solution or which can be used for applying the medicated solution externally to any portion ofp-the body.

- The ordinary medicine dropper is .objectionable because when it is desired to measure a certain number of drops of medicated solution it requires a great deal of practice in order to obtain the right nllmber of-drops and not to exceed such number, thatlis, if it is desired to obtain ten drops a stream gof the medicine may flow from the dropper instead of a certain numberof separatedrops, and thusthe amount of medicated {solution measured is rendered inaccurate. With the v improved medicine dropper illustrating the same attached to a bottle.

Fig. 2 is a front elevation of the medicine dropper removed from the bottle, a part of the same being broken away and shown in section.

Fig. 3 is a sectional elevation showing a modified form of the lower end of the v dropper.

Fig. 4 is a sectional elevation of a modi- 4 fied form of tube.

Like numerals refer to like parts throughout the several views of the drawings.

Specification of Letters Patent. Patented Aug, 19, 1919,

Application filed April 1, 1918. Serial No. 225,856.

In the drawings 5 is a bottle having a neck portion 6 with an annular groove 7 therein. 8 is the dropper consisting of a tube 9 with a collapsible bulb 10 attached to one end thereof, the tube having a flange 11 at its upper end which is embedded in the collapsible bulb 10. Said tube is surrounded for a portion of its length,-adjacent to the upper end thereof, by a sleeve 12, preferably formed of rubber and integral with the collapsible bulb, 10, said sleeve forming a around the upper portion of the bottle and the lower portion of the flange 13 to make a water-tight joint between the stopper and the bottle.

The closure of the bottle consists, therefore, of the sleeve 12, the flange 13 and the collapsible bulb 10. The tube 9' terminates at its lower end in an enlarged portion 15 which contains a chamber 16 in which is inclosed a portion of a conveyer 17.

In-Figs. 1 and 2 this conveyer consists of a piece of absorbent material forced into the chamber 15 and having a pad 18 projecting beyond the lower end of the tube 9.

In Fig. 3 a modified form of the invention is illustrated in which the conveyer 17 consists of a brush, preferably of camels hair and projecting beyond the lower end of the tube 9 'toform a brush portion 19.

In use, the strip 14 is removed from the bottle and the closure is withdrawn from the bottle, together with the tube 9. The bulb.

10 is collapsed by pressure of the finger and thumb of the user. The tube is then inserted in the bottle until the lower end of the tube enters the medicated solution 20. The pressure upon the collapsible bulb is then released and the medicated solution enters the tube 9 through the conveyer 17, as illustrated in Fig. 2. Then, if the device is used to apply the medicated solution extion of the body which it is desired to treat and asuflicient pressure is exerted upon the collapsible bulb 10 to force the medicated solution through the conveyer 17 into the pad portion 18. When enough of the solution has, however, been applied, the presternally, the pad 18 is'rubbed over the porsure upon the bulb 10 is releasedand the medicated solution is then drawn back into the tube by-reason of the partial vacuum in said tube caused by the release of the collapsible bulb.

When it is desired to use the device as a dropper the bulb 10 is compressed until the medicated solution is forced drop by drop through the conveyer 17 and off the end of the pad 18 or of the brush 19, as the case may be. i

In Fig. 4 a modified form of the tube 20' for the dropper is illustrated in which the walls 21 at theupper end of the tube are thicker than the walls 22 at the lower end of the tube. The object of this construction is to give additional strength to the tube at the upper portion thereof, as tubes of this character are very often broken at the upper end where the collapsible bulb is attached to them on account of the strain to which they are subjected in use.

While I have described my invention as being particularly adapted for applying medicated solutions 'externallyto any portion of the body, it is evident that without departing from the spirit of my invention the invention may be utilized for other purposes, such, for example, as for applying li uid blacking to boots and shoes.

Iaving thus described my invention, what I claim and desire by Letters Patent to secure is: p

1. A medicine dispenser having, in combination, a tube, a closure for a bottle attached to one end of said tube, said closure consisting of a colla sible bulb and a sleeve integral therewit constituting a stopper and adapted to project into and fit the neck of a bottle and a wad of absorbent material inserted in the opposite end of said tube.

2. A medicine dispenser having, in combination, a tube, a closure for a bottle attached to one end of said tube, said closure consisting of a collapsible bulb, a SIGGXG integral therewith constituting a stopper and adapted to project into and fit the neck of a bottle and a flange integral with said sleeve and encircling the outside of the neck of said bottle.

3. In combination, a bottle having a neck, said neck being provided with an annular groove, a tube, a closure consisting of a collapsible bulb, a sleeve fitting said tube and constituting a stopper for said bottle and a flange thereon encircling the neck of said bottle and projecting into said annular groove.

4. In combination, a bottle having a neck, a tube, a closure consisting of a collapsible bulb, a sleeve on said bulb fitting said tube and constituting a stopper for said bottle, a flange thereon encircling the neck of said bottle and a strip of material encircling said closure and bottle at the juncture of said flange with said bottle.

5. A medicine dispenser having, in combination, a tube, a closure for a bottle attached to one end of said tube, said closure consisting of a collapsible bulb and a sleeve integral therewith constituting a stopper and adapted to project into and fit the neck of a bottle, and a piece of absorbent material attached to the opposite end of said tube.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
