SPECIFICATION forming part of Letters Patent No. 783,688, dated February 223, 1905.

Application filed May 2, 1904. Serial No` 205,934.

Be it known that li, JOHN C. DUJAT, a citizen o'l the United States, and a resident ot' New York, in the county of New York and State et' New York, have invented certain new and use- :Ful Improvements in Medicine-Droppers, oli which the following is a specification.

The present invention relates to a medicine dropper, and has for its object to arrange a device to be applied to a medicine-bottle by means ot' which the liquid contained in the bottlc will be allowed to flow in drops, and thus enable the patient to take the right number of drops. The arrangement of this device is such that it can be readily attached to bottles with necks of different sizes.

The device consists of a conical 'funnel oli' any suitable materiahpreferably oi' glass. The top and the bottom ofthe funnel are open, the hole of the bottom being sufficiently narrow to permit the liquid to iiOw in drops. At its back the funnel is provided with a lateral pro jection serving to bear a spring-clasp, which may be made of suitable spring material and adapted to engage the neck oi' a medicine-botn tle. rllhe device is to be applied to the bottlc crosswise to the longitudinal dimension 'of the latter, so that when the bottle is tilted over to pour out the liquid the funnel will extend downward and the liquid flowing into the funnel will flow out from the funnel in drops.

The present invention also relates to some other means, which will be hereinafter more particularly speciiied.

In order to make my invention more clear, the same is illustrated in the accompanying' drawings, in which similar reference-numerals denote similar parts, and in whicl Figure 1 is a vertical section of the device, the latter being' shown in use and as applied to a medicine-bottle; Fig. 2, a front view of the device; Fig. 3, a top view thereof; Fig. t,

glass, this latter material being antiseptic. As seen from the drawings, the tunnel has an open top and bottom, the hole G ot the bottom being1 sullieiently narrow as te cause the liquid to low out in drops. At its back the funnel l is provided with a lateral projection 5, serving as a bearing tor a clasp 3, which may be made of a strip oli' resilient material, as metal, hard rubber, or the like, and is attached to the projection 5 by simply bending this strip around the latter. llo prevent the turning of the clasp 3 upon the projection 5, the latter may be made oblong, as shown, or square. At one side ot' the 'tumiel a spout 7 may be provided to allow the surplus liquid to be poured back into the bottle. 'llo prevent a lateral displacement ot' the clasp 3 upon the projection the free end oil thelatter may be provided with a V[lange securing the clasp 3 in position.

ln order to apply the device to a medicinebottle, the neck ol the bottle is placed between the two ends ot' the clasp and the latter is pressed upward, whereby the spring-arms ol the clasp will be opened and engage the neck 2 ot the bottle l, as shown in the drawings.

A scale denotingl the number el drops eontained in the funnel at a particular partthereot may be provided on the outer surlaee oli the glass funnel, whereby the patient will be enabled to always control the number el' drops to be taken.

In Figs. 4, 5, and 6 a medilication olE the above-described arrangement is shown. ln this modiiication the spout does not extend outward as in the lirst arrangement, but a spout 9 is arranged inside the funnel Ll, so as to project into the mouth ol the bottle when the funnel is applied to the latter. This spout may be at its inner end wider than at its onteiend in order to permit the liquid to be easier poured back into the bottle when the latter is turned upright.

lt will be seen that when the funnel is applied to the bottle and the latter tilted over into the position shown the liquid contained in the bottle will iiew into the tunnel through and around the spout, while when the bottle is turned upright again the liquid will l'low back into the bottle through the spout El. l

IOO

do not confine myself, however, to the particular arrangement shown, as it will be understood that various changes ot' the di'erent parts may be made without departing from the spirit of my invention.

That I desire to secure by Letters Patent l. A medicine-dropper, comprising a conical funnel of any suitable material, preferably of glass, said funnel being provided with an open top and bottom, the hole of the bottom being suiiciently narrow to cause the liquid to flow out in drops, a lateral projection at the back of the funnel, a clasp borne upon said projection and adapted to engage the neck of the medicine-bottle in such a manner that when the bottle is tilted over the funnel will extend downwardly crosswise to the longitudinal dimension of the bottle and permit the liquid to flow into the funnel, substantially and for the purpose as specified.

, bottle, a scale on the outer surface of the funnel, a spout inside the funnel, said spout projeoting outward and being curved so as to project into the neck of the bottle when in use, substantially and for the purpose as specified.

Signed at New York, in the county of New York and State of New York, this 30th day.

of April, 1904.
