This invention Irelates to a. liquid measuring device and it is an 1 object for 7 this" invention to producea self-measuring top for repeatedly dispensing predetermined quantities zof liquid content material, one after' anoth'erarit short 'time intervals, while the-bottle orother vessel containing the liquid- -contentmaterial is held tin 1 pouring position.

Another 1 object is -to produce 1 the self:*meas 'uring repeating top of the-type described, which is'providedwith means for preventingiloss or withdrawal of liquid content material from the bottle or vessel, other than --when-the bottle is held in pouring position.

A further object is 1 to "provide; in combina tion with a self-measuring repeating top or the type described," a *metering device Which automatically records the numberof measured units which have been dispensed from the bottle" top.

The valve member shown is in the form of a ball 3! housed for slight movement within an enclosure defined by the front wall of the chamber 54 and vertically spaced horizontally disposed upper and lower walls 56 and 5?. The upper wall has a depending end flange 58 and the lower wall has a rim 58a which provides a socket for the ball when the bottle is in the upright position. The ball prevents the use of the vent hole as a means for removing the liquid, even when the container is in an inverted pouring position. While seated in the socket the ball 3| closes the vent 55 thereby to prevent loss of content material. Responsive to gravitational force, the ball moves away from the vent open ing when the bottle is raised to pouring position. It will be understood that other valve means may be provided in the passage to give a corresponding effect.

To prevent the escape of content material from the dispensing conduit IS, the conduit is provided with a ball 28 arranged within the conduit between a cross rod 30 and a tapered sleeve 29 in the conduit. The cross rod 30 prevents loss of the ball when the bottle is raised to pouring position and the ball seats in the sleeve 29 when the bottle is other than in pouring position, thereby to close the opening through the conduit l6 and prevent 1 the escape or loss of content material.

A bafile I is provided in the lower portion of the measuring chamber. The bafiie extends from the forward wall of the cap and beyond the supply and air pipes l3 and I1 and it is downwardly inclined to drain content. material in the measuring chamber toward the pipes when the bottle is in. upright position.

The measuring device operates on a siphon principle. For pouring, the bottle is tilted to a position whereby the spout I0 is ,down and the dispensing conduit l and the cup l5 are sub- When in this position, air

l5, into air pipe I1, to replace liquid content material which drains through the supply pipe 13 into the measuring chamber 50.

Filling of the measuring chamber continues in this manner until the level of the liquid rises to the inlet end of the conduit l6, whereupon siphoning commences. I to rise through the conduit I6 or enter the cup l5 from the vent 9. Thus, air is out off from the At this point, air is unable chamber continues until the fluid level has reached the lower open edge of the cup member l5, whereupon air passage to the air pipe H is reestablished and fluid no longer passes through the conduit. This frees the conduit for air supply and the described cycle is repeated.

This consecutive filling and siphoning of measured quantities of content material continues so long as the bottle is ;held in pouring position. It will be evident that the amount of liquid entering the measuring chamber is constant and precletermined by the length of the cup I5 and the distance which the conduit 16 extends into the cup. The time lag'occasioned for refilling the measuring chamber before siphoning can again take place is usually suflicient for changing receiving vessels, if desired. In the event that the time lag is insuflicient, it may be slowed by various means designed to restrict the flow of content material into the measuring chamber, such as by restricting the rate of air flow into the bottle or by restricting the rate at which content material may drain from the bottle into the measuring chamber.

To record the number of cycles through which the dispenser has gone, the measuring chamber is provided with an actuator arranged therein comprising a float l8 carried on one end of a pair of V-shaped lever arms 59 and 60 having outturned ends GI and 62 respectively pivotally mounted in suitable bearings formed in the shell walls. A spring dog 2| is carried by one of the arms 60 intermediate its ends. The spring dog normally rests on a pin 22 but when the float rises with the level of liquid in the measuring chamber, the operative end 63 of the spring dog engages one of the numbered rack teeth 23 arranged in measured spaced relation about the periphery of a ratchet wheel 64 which is mounted on the some float arm for free turning movement.

Inadvertent turning movement of the ratchet wheel is prevented by a lock spring 24 which is se cured at one end to the underside of wall 56; The free end of the lock spring engages the rack teeth to provide a steadying action. The ratchet wheel 64 is formed of one tooth missing, as at 26 before the zero position, to prevent the spring dog 2| from actuating the ratchet wheel beyond the highest numbered tooth. Numbers 32 may be applied to indicate each tooth or to indicate a certain number of teeth, as shown in Figure 5. Numbering may be accomplished with substances visible in ordinary daylight or they may be formed of fluorescent materials visible only under black light.

The ratchet wheel is adjusted to indicate a desired number by an adjusting bracket shown in Figure 4 which is disposed within the area defined between the baflie l0 and the lower wall of the cup. The adjuster consists of another spring dog 25 on the outer end of a body portion 65 which is pivoted from the slotted portion 66 about the air pipe [1. The other end is provided with an upturned spring member 61 which engages the under side of the baffle 10 in a manner constantly to urge the adjuster to rock in a counterclockwise direction. To adjust the ratchet wheel, it is necessary to work through the sup ply tubing 13 with a rod, indicated by the numeral H. The rod is actuated to the end portion 25 causing the adjuster to rock in a clockwise direction and bring the upturned end 61 into onerative engagement with an adjacent tooth. The ratchet wheel is turned one step responsive to the spring action upon withdrawal of the rod II.

This arrangement permits accurately dispensing measured amounts of content material in repeated fashion with means embodied within the device accurately to record the number of units which have been dispensed. Such recording cannot be disturbed other than by removal of the measuring cap which would be indicated by breaking the seal formed thereon, indicated by the numeral [2. To prevent actuation of the ratchet wheel by any other manner than by raising the bottle to pouring position a pivoted stop 21 is provided having a free end portion 68 which extends into the path of the float 18 while the bottle is in upright position. The stop is in the form of a bell shape lever suspended intermediate its ends over the pin 69 extending from the shell 115 wall. 'Thedependingporti'on Not the bell lever f.is"weighted"torockthe stop out 'ofposition; as ""shownby the broken lines, when thebottleis "raised to pouring position. This "permits "the heat 18 to rise to the position "shown by v the broken lines as the levelof the liquid rises inthe measuring chamber. The actuator therefore can only operate to turn the ratchet wheelresponsive to the risein liquid level when the bottle is'raised to pouringposition.

"From this descriptionit will'be apparent that ""wehave provided a new and improved dispenser top for repeatedlydispensing measured quantities of content material'whilethe' bottle'is held in pouringposition. Our device embodies features which'prevent loss of content material from the "cap through any intention by the operator other 'than for dispensing measured quantities of liquid f wh'ich are automatically calculated and recorded 3 by reaction of elements'embodied therein.
