FRANKLIN M. DIXON, OF PHILADELPHIA, PENNSYLVANIA.
DRO PPlNG-BOTTLE.
SPECIFICATION forming part of Letters Patent No. 246,477, dated August 30, 1881. Application filed January 526, 1881. (No model.)
To all whom it may concern:
Be it known that I, FRANKLIN M. DIXON, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Dropping-Bottles, of which the following is a specification.
My invention relates to certain improvements in the dropping-bottle for which Letters Patent were granted to me on the 2d day of November, A. D. 1880, the objects of my present improvements being too fully described hereinafter to need preliminary explanation.
In the accompanying drawings, Figure 1 is a vertical section of my improved droppingbottle; Fig. 2, a plan view, Figs.3 and 4, views of part of Fig. 1, with some of the parts in different positions; and Figs. 5 and 6, detached perspective views of the stopper and a valve with which the same is provided.
The device is similar in general construction and operation to that formerly patented, A being the bottle, B the sliding stopper,and D the dropping-tube carried by said stopper, having its lower end submerged in theliquid, and bent at its upper end, so as to deliver drops of the liquid into a suitable receptacle on forcing the stopperB into the bottle. Rubber was found to be the best material of which to make the stopper B; but as itwas necessary to have the stopper of a certain length in order to obtain the proper bearing, said stopper, if made solid throughout, proved to be costly, and its lower edge would not yield to accommodate itself to slight inequalities on the interior surface of the bottle. In order to overcome these objections, I make the lower portion, a, of the stoppersay for about one-third of its lengthtubular, thereby lessening the weight of the stopper and providing a flexible lower portion which can yield readily. It was also found to be difficult to properly govern the dropping of the liquid by the forcing in of the stopper, the compression of the air in the bottle being such that the liquid continued to drop from the tube D after pressure had been removed from the stopper. An increasein temperature also caused the discharge of liquid from the tube, owing to the expansion of the air in the bottle.
In order to overcome these objections, I form in the stopper B, in addition to the opening for the tube D, an opening, I), to which is adapted a valve, F, consisting, in the present instance, of a stem, d, having at the upper end a suitable head or enlargement, c, and at the lower end a bulb, f, the stem d being snugly fitted to the opening I), and the bulb f being adapted to a seat formed by enlarging the lower end of said opening. In one side of the stem 61 is formed a groove, i, which extends from the top of the bulb f to the top of the stem, so that when the valve is drawn up and the bulb adapted to its seat, as in Fig. 1, communication with the interior of the bottle through said groove is cutoff; but on depressing the valve to the position shown in Fig. 1 air can pass freely from the interior of the bottle through the groove. When the bottle is in use the valve F is closed, as in Fig. 1, and the stopper is depressed, as usual, to cause the flow ot' the liquid through the tube D. When the proper number of drops has been delivered, however, the valve is opened,so that the pressure within the bottle is relieved and the flow terminates instantly. The valve being allowed to remain open during the time that the bottle is not in actual use, expansion of the air in the bottle due to an increase of temperature cannot effect the discharge of liquid through the tube D.
In the top of the stopper B are two recesses, m and n, the former being adapted for the reception of a vessel, 8, so arranged in respect to the bent upper end of the tube D that the latter may be turned so as to terminate above and discharge liquid into the said vessel. (See Figs. 1, 2, and 4.) The recess a is so arranged in respect to the tube D that when the said tube is depressed the bent end of the same may be adapted to the recess, as in Fig. 3. The entrance of dust into the tube or bottle, or the evaporation of the contents of the bottle when the latter is not in use, is thus prevented.
The valve F is introduced into its place from above, the stopper being sufiiciently elastic to perm-it the passage of the bulb 1" through the opening I). This form of valve is not absolutely essential in carrying out my invention, although it is preferred, as it is simple in conhaving a bent upper end, the stopper having a Is recess, m, and the vessel 8, adapted to said recess, as described.
5. The combination of thedropping tube having a bent upper end with the stopper having a recess, n, as set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
FRANKLIN M. DIXON.
