7 Claims.

This invention relates to improvements in apparatus of the type disclosed in United States Letters Patent No. 1,862,801, dated June 14, 1932, for delivering measured quantities of liquid from bottles or similar vessels, and has for its objects the provision of a device or apparatus, of the above type, in which the body of the device and certain of the elements, are adapted to be molded or cast from plastic material or metal in few pieces which pieces are adapted to be quickly assembled with a cork and other simple pieces to provide a leak-tight, durable, simple unit that is more efficient in operation than has been the case heretofore, and which unit is adapted to withstand long and frequent usage to measure and pour aqueous or alcoholic fluids, or the like.

Other objects and advantages will appear in the following description and drawing.

Briefly described, this invention operates in generally the same manner as the device dis closed in United States Letters Patent No.

ments included in the device and the necessity for making frequent replacements in the cork has been highly objectionable. These are only a few of the problems that have been faced by makers of devices of this character, and which this invention has solved. The device of this invention, in general, comprises a hollow body with air and liquid inlet pipes at one side thereof extending through a cork adapted to fit within the neck of a bottle or similar device, and means is provided at other points on the body for the discharge of liquid from within the shell and for admission of air to within the same from outside the vessel on which the device is positioned.

In the detailed'description and claims that follow, the reference to vertical or vertically refers'to the position of the device when upright on a standing or upright bottle or vessel, when the same is not in use, Since when in use the bottle is tilted in the ordinary manner for pouring from the neck. I

In the drawing (Figs. 1 to 3) the device is 11- lustrated in said vertical position. Also the terms used to describe the positions of various elements in my device, are used with reference to the device in the position shown in the drawing, except where it is clear that some other position is intended.

The body of the device, illustrated in the drawmg, comprises a hollowspherical shell, generally designated l of molded plastic material, such as Bakelite, or it may be of metal which is plated or of a character to resist the action of the liquicls1 in connection with which the device is to be use On the lower side of the shell, and integrally therewith, is formed an outwardly extending, frusto-conical projection 2, formed with a pair of adjoining, cylindrical, passageways therethrough adapted to pass a pair of pipes 3, 4 in side by side, parallel relationship. The base of frustoconical projection 2 is adjacent the body of the shell, and the centralv axis of said projection passes through the center of the shell.

A cylindrical, outwardly extending projection 5 is formed on the shell, and integrally therewith, at a point on the side thereof spaced vertically around the shell from projection 2, which projection 5 is formed with a cylindrical passageway therethrough, the axis of which extends from the center of the shell at about 131 degrees with respect to the axis of projection 2. A liquid discharge conduit 6 is adapted to pass through said passageway, coaxial therewith, to a point within the shell extending slightly past the center of said shell and the outer end of said conduit extends outwardly of projection 5.

At the side of the shell opposite projection 5 the shell is formed, internally with a vertical, cylindrical passageway l, for air, the said passageway opening at one end outwardly of the shell flush with the outer surface of the shell. The walls of said passageway are integral with the walls of the shell, and the lower open end of said bafile terminating at a point about a quarter of the distance across the distance between the" wall of the baffle from which it extends and the opposite wall.

At a level below baffle 8, and spaced above the bottom of the shell, a partition 9 extends inwardly from the side of the shell I opposite bafile 8. Said partition is integral with'the walls of the shell and extends across the openings for pipes 3, 4 andterminates in a freeedge short of the inner free edge of baflie 8. w The contour of the upper side of said partition along the free edge, is generally concave, or of a relatively flattened V-shape and thecentral portion of said partition at right angles tosaid free edge is inclined downwardly' from the wall of the shell with which it connects, thus forming a drain for drawing liquid back into the receptacle that carries my device.

The margin of partition 9 adjacent its free edge, is formed with an opening adapted to pass therethrough the upper end of pipe 4.

The projections I, 2, passageway l, baffle 8 and partition 9 are formed integrally with the walls of the shell, and all of said elements are disposed in a single vertical plane bisecting the shell, so that said plane bisects all of said elements. Shell l is bisected along said plane, leaving one-half of each of the above mentioned elements along the line of division.

When the halves of the shell are assembled a centrally apertured cap II] is fitted over projection 5 and a cap II with a tapered central opening corresponding to the tapered sides of projection 2, is fitted over said latter projection, thus tightly securing the halves together.

The annular free edge of one-half of the shell fits within an annular recess formed around the free edge of the other half, as best seen in Fig. 3, to insure aligning the halves.

Within said shell, and above the partition 9, is the usual siphon, consisting of a cylindrical body l2 that is inclined almost to the same degree as conduit 6. The upper end of said body is open and the lower end is closed by a head 53. The lower side of the lowered -end of body i3 is formed with a cylindrical, downwardly extending projection 14 that is centrally apertured to receive the upper end of pipe 4, and the upper end of said latter pipe is cut off at a, relatively steep angle so as to provide a lip I5 projecting upwardly onto said siphon body on the side of pipe l nearest the side of the shell through which conduit 6 projects, while the lowered edge of the upper end of pipe 4 is adjacent the juncture between the lower inner side of said body l2 and the head l3. Thus any liquid within body l2 will drain into pipe 8 when the bottle carrying the shell is vertical.

One side of the projection I4 is formed in substantially downward continuation of the head I 3, and said side is formed with a downwardly projecting lug IB that is adapted to fit within a corresponding recess in the free edge of partition 9, thus positively insuring against any turning of the body l2 when the latter is in place.

The cap N that surrounds projection 2 is formed with a downwardly extending flange ii that is adapted to fit over the upper end of a cork I8. Said cork i8 is formed with passageways adapted to tightly pass the pipes 3, 3 therethrough, and when the cork is in position its upper end is supported against the downwardly facing shoulder extending inwardly from flange ll.

From the foregoing, it will be apparent that the halves of the shell, which includes bafile 8, partition 9, passageway I, and projections 2, 5, are readily die cast, or molded.

In assembling the device, pipes 3, 6, 6 are laid in one of the halves, with the upper end of pipe 3 flush with the inner surface of the lower side of the shell, and body i2 is secured to the upper end of pipe 6. Then conduit 6 is positioned within body 12 with its lower end slightly extending over the upper open end of pipe 4. The other half of the shell is then positioned over the assembly of elements, and caps l0, ll positioned over projections 2, 5 and the entire apparatus is completely assembled and ready for use, as soon as cork I8 is slipped over pipes 3, 4. All joints between the halves themselves, and between the pipes and conduit 6 and the halves, as well as between the caps and projections 2, 5, and between the body 12 and pipe 4, are preferably connected so as to insure against any possible leakage, and to also make the apparatus a substantlally integral unit.

The space H) below partition 9 receives liquid from pipe 3 when the device is tilted to pouring position, and the chamber 2| on the other side of said partition forms the measuring chamber. The bafile 8 is to prevent liquid from splashing into the vent or passageway 1 during pouring, and by forming said passageway against the side wall of the shell, it is manifest that the hazard of accidental spillage through the vent is eliminated, whereas in the devices heretofore, with the vent projecting into the area within the shell, such spillage was prevalent.

The terminating ofthe upper end of the liquid pipe l flush with the. inner side of the shell wall, enables the accurate and efiicient successive pouring of measured amounts of water, aqueous solutions, and other liquids, as well as alcoholic liquids, a result that cannot be accomplished where said pipe projects into the area within the shell in the manner that heretofore has been done.

Also, the use of the two pipes 3, 4 alongside each other, in combination with the walls of the passageways in cork l8 being formed to tightly seal against said pipes, as indicated in Fig. 4, reduces the replacement of corks to ,a'1 :fraction of the need for such replacements are devices where a single large pipe is used with the other pipe extending through the same. In Fig. 4 my construction is most clearly shown. the tight seal and added strength being due to greater amount of material remaining in the body of the cork itself after being bored for the pipes, and in which structure, ribs 28 are at the juncture between the passageways for the pipes.

While I have stated that the several parts of my device are cemented together, it is obvious that where metal is used, for the shell and siphon, they may be soldered or welded in place. ever, the use of a shell of molded plastic or the like is preferable, due to the lack of necessity for plating and the fact that the material is light in weight, and can be molded very thin, all of which features are highly desirable.

Of the improvements in my device, the following are perhaps of greatest importance, namely:

(1) The provision of a vertically split shell carrying the baffle and partition integral therewith and with the pipe and conduit apertures formed along the line of division.

(2) In combination with a cork support for the shell, the provision of the air and liquid inlet pipes in side by side relation where they extend through the cork.

(3) The provision of the air inlet from the outside, to the area within the shell, which inlet is cast in the shell wall.

(4) The termination of the pipe 3 flush with the interior of the shell:

(5) The provision of means on the siphon to prevent its turning, or dislodgment thereof from its normal position.

How-

(6) The simplified method of assembling the apparatus to form a unitary device.
