, `2 Claims.

, 110 a device 'of this character which is designed parp ticularly for dispensing and measuring ice cream or like material. f Y I l I A `further object ofthis invention is to provide a device of this character which is readily `l cleansed and wherein the `measuring means is contained entirely within the rotatable valve member.

A still further object of this invention is tor provide a device of this character which may be readily attached to or removed from a container, the device having a straight opening therethrough which is intersected by a measur- `ing means and the material being ejected by the pressure `applied to the container.

` With the foregoing and other objects in View,

the invention will be more fully described hereinafter, and will be more particularly pointed out in the appended claims.

In the drawing, wherein like symbols refer to like or corresponding parts throughout the several views:

Figure 1 is a detail side elevation of a measuring valve constructed according to an embodiment of this invention.

Figure 2 is an enlarged vertical section, partly in detail, of the valve.

Figure 3 is a fragmentary sectional view taken on the line 3--3 of Figure 2.

Referring to the drawing, the numeral III des- 10 ignates generally a valve housing whichis adapted to be secured to a suitable container having plastic or semi-plastic material disposed therein. The thereto which is provided with exterior threads I3 which are adapted to engage a suitable connection carried by the container to which the housing I6 is connected. The housing I0 has a bore or measuring opening I2 therethrough which at one end communicates with the bore of the nipple I3 and the other end of the opening or bore I2 extends through a boss or enlargement I4 which constitutes the discharge end of the bore I2. The opening I2 through the housing I6 is of the same diameter as the interior diameter of the nipple I3, and the opening housing I6 has a nipple II secured l through the discharge nozzle I4 is also of the same diameter as the bore I2.

The housing IIJ is also provided with a tapered valve seat or opening I5 disposed at right angles to the bore I2 and intersecting the bore I2-` A 5 tapered valve member I6 engages inthe tapered opening I5, and this Valve member I6 is provided with a passage therethrough which is Y adapted to register with the bore I2 when the valve member I6 is in open position. One end l0 of the valve member, and in `this instance the large end,`is provided with a'handle I8 which may be cast integral with the valve member I6 or may be secured thereto in any suitable manner. l5

The other or reduced end of the valve member I6 has a thumb screw I9 threaded thereinto, and

this thumb screw extends `through a plate 20 which engages against the adjacentend of the A housing I0 so as'to hold the valve member I6 in '20 operating position in the tapered opening I5. The opening I1 in the valve member I6 constitutes the measuring means for "the material passing throughthe housing III,` andin order A to provide a means whereby the material to be 25 measured may not freely pass through the valve member I6 when this valve member is in open position, I have provided a plunger, generally designated at 2l which is slidable in the opening or cylinder I1. The plunger 2I is constructed 30 of a pair of discs 22 and 23 which are secured together by means of an axially disposed bolt or screw 24. A spacing member 25 is interposed between the discs 22 and 23, and this spacing member 25 provides a means whereby the quan- 35 tity of material to be dispensed may be varied without the necessity of providing a new plunger.

The plunger 2l is held against rotation in the cylinder or bore I1 by means of diametrically opposed keys 26 which slidably engage in key- 4o ways 21 provided in the cylinder or bore I1. A pair of removable stop pins 28 and 29 are mounted in the valve member I6 and have their inner ends projecting into the keyways 21. The pin 28 is locked against movement by means of a 45 set screw 30, and the pin 29 is locked against movement by means of a set screw 3l. The pins 28 and 29 are disposed adjacent one end of the keyways 21, whereas stop members 32 and 33 are disposed in the keyways 21 adjacent the 50 opposite ends thereof, these stop members 32 and 33 being constructed in the form of pins Vor threaded members, and preferably the ends of the keyways 21 projecting beyond the stop members 32 and 33 are filled up by solder 34 or 55 material to be diswill yregister with: the bore I2, and in this position the material in the container will pass through the nipple `I3 and force the plungerV 2| outwardly to the limit of the stops 28-29 or the stops 32-33, depending only upon the manipulation of the handle I8. When the cylinder I'I is filled with the material and the plunger 2| is forced outwardly to its limit, the handle I8 is. then turned through an arc of one hundred and eighty degrees so that the plunger 2I will be diswhich is applied to the material in posed in an innermost position. 'I'he pressure the container will then force the plunger 2| outwardly, and outward movement. of the plunger 2I will eject all of the material in the cylinder IT-through the nozzle I4. The plunger 2I 'is forced outwardly by the material moving through the nipple I3, and when the plunger 2I reaches itsv outermostposition Ythe cylinder I1 will again be illled so that each half turn of the handle I8 and the valvemember I6 will dispense a measured quantity of material. Y

Y,It will be apparent from the foregoing that an'exceedingly simple measuring valve has been devised Y which will `measure a predetermined quantity of material, and that the quantity of material to be measured and dispensed may readily be changed when the need therefor exists by merely changing the size of the spacer 25. Furthermore by providing `a valve member witha straight opening therethrough and having a nozzie or discharge means of the same size, the material to'be ejected will be more rmly packed andi present a better appearance than where a small discharge opening is used which is relatively smaller than the plunger.

It is obvious that various changes and modications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.

What is claimed is:

1. A dispensing and measuring valve comprising a housing having a passage therethrough, a valve member intersecting said passage and having an opening therethrough adapted to register with said passage when the valve member is in open position, said valve member having a pair of diametrically opposed keyways in the opening thereof, a plunger slidable in said valve member opening, keys carried by the plunger engaging in said keyways, stop members carried by the valve member adjacent one end of the opening,

a pair of removable stop pins carried by the v valve member adjacent the opposite end of the opening, and means for removably securing said stop pins in the valve member.

2.A 'dispensing and measuring device comprising a housing having a substantially vertical opening therethrough for the movement of material, a plug valve mounted in said housing for rotation on a substantially horizontal axis and having an opening therethrough adapted to register withthe vertical opening in said casing, said plug valve having key-ways therein communicating with the opening, a plunger mounted to reciprocate in the'opening in said plug valve and composed of an intermediate iiat spacing block, a pair of discs abutting said block, one disc being on each side of the block, said discs having keys thereon for riding up and down in said key-ways and means for binding said pair of discs to said block, and stop members projecting into said key-Way at opposite sides of said plunger and positioned to encounter said keys to restrict the throw of the plunger.
