MEASURING AND DISPENSING DEVICE Filed Feb` 12. 1942 INVENTOR.

Patented Feb. 29, 1944 UNITED STATES PATENT OFFICE MEASURING AND DIsPENsING DEVICE Martin Pearl, Perth Amboy, N. J.

Application February 12, 1942, Serial No. 430,599

(Cl. 221-9S) 1 Claim.

This invention relates to attachments for containers of liquids or other materials that can be poured, and is adapted to regulate the delivery of said materials from said containers.

An object of the invention is to provide a device of this kind Which can be readily secured to the mouth of the container, and which is so constructed that it Will measure out and issue a predetermined quantity Whenever the container is actuated to assume discharge position.

Another object is to provide such an attachment comprising few parts and capable of being easily manufactured at 10W cost.

The advantages of the invention are set forth in the following description, and the novel features are recited in the appended claims; but the disclosure is explanatory only and Various changes in shape, size and other details may of course be adopted in practice.

On the drawing:

The single gure is a longitudinal section of an attachment according to my invention.

My improvement embraces a shell or casing I, the interior of Which is divided into tWo chambers 2 and 3 by a transverse partition d. The shell has a neck 5 which has a covering of some compressible substance, such as cork 6, to be inserted tightly into the mouth of the container, such as a jug or bottle.

The neck 5 extends through the chamber 3 and communicates With the chamber 2. Its inner end is controlled by a valve l, the movement of which is limited by a cage 8. The chamber 3 has a spout 9, secured around an opening in the partition 4. This partition does not extend entirely across the inside of the shell i, but has a downturned edge I Which leaves an opening I I between the chambers. An air tube I2, opening through the wall of the chamber 2 on the side opposite the spout, and extending through the recess II', projects into the chamber 3.

In use, the container is tilted to the left and the contents run past the valve 'I into the chamber 2; some of the air in the shell escaping through the tube I2. As soon as the level of the liquid rises in the chamber enough to cover the inner end of tube 5, no more liquid can enter this chamber. When the container is righted, the valve 'I closes and liquid in the chamber 2 runs down into the chamber 3 through the opening I I. By the tilting of the container again, the person holding it causes the liquid in the chamber 3 to issue from the shell I by Way of the spout 9, which extends to the exterior of the shell; air now entering by the tube I2. At the same time the upper chamber 2 is relled.

The operation is thus repeated as often as the container is manipulated. This attachment thus served to deliver the liquid in measured quantities only; corresponding to the size of the device.

Having described my invention, What I believe to be newl and desire to secure and protect by Letters Patent of the United States is:

An attachment for a container comprising a shell With a partition inside dividing the interior into a pair of chambers, a neck projecting from the shell to be secured to the mouth of the container, said neck having an extension running through the partition and communicating with one of said chambers, said partition having an opening at one side to connect said chambers, a spout in the chamber with which said extension communicates and affixed to the partition at the side opposite said opening, said spout communieating with the other chamber and extending to the `outside of said shell, a non-return valve in the neck extension adjacent the partition, and an air tube attached to the Wall of the chamber With which said extension communicates and extending into the other chamber and open to the atmosphere through said shell.
