MEASURING-FAUGET FOR URNS.

7 Specification of Letters Patent.

Patented July 4,1916.

Application filed May 15, 1913. Serial No. 767,809.

To all whom it may concern:

Be it known that I, HENRY D. KELLY, a

citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Measuring-Faucets for Urns, of which the following is a specification.

This invention relates to dispensing valves and has for its object a valve for cream dis pensing cans which will operate with a minimum amount of dripping to deliver measured quantities of cream .in quick succession.

Another object is to provide means for agitating thecontents of the dispensing can through the operation of the valve.

With these objects in view, the invention consists of certain novel and peculiar features of construction and combination as hereinafter described and claimed; and in 'order that it may be fully understood reference is to be had to the accompanying drawings, in which Figure 1, is a vertical section, partly broken away, of a dispensing can provided with one form of my improved valve. Fig. 2, is a vertical section through the faucet portion of a can, showing another form of valve, the operating lever and lever connections being shown in side elevation. Fig. 3, is a plan view of the parts shown in Fig. 2.

Referring to the drawing, the dispensing can 2 for cream or other liquid has its bottom 4 provided with a channel portion 6, leading to the discharge opening of the can. The discharge opening of the channel portion 6 is surrounded by a threaded collar 8, which is securely and tightly fastened in place about the opening by means of screws 10 and packing 12.

Extending into the opening to the channel portion 6 and threaded to engage the collar 8 is a faucet casing 14, equipped with a nozzle 16, the opening into this nozzle being bridged by a series of ribs 13.

In the form of the invention shown in Fig. 1, the nozzle 16 is provided with a lug pin 23, this lever having a handle 28 and being pivotally connected intermediate its ends by a pin 30, to the outer end of a rod 32,

the other end of which is threaded into the body portion of a valve 34. The rod 32 operates through an. opening 36 in a flanged cap 38 which is suitabl threaded to engage and close the outer en of the casing 14.

The body portion of the valve 34 is of smaller diameter than the casing 14 and is provided with a pair of annular flanges spaced apart a distance sufficient to give the valve' the required measuring capacity, the amount dispensed by each operation of the valve being determined by the size of the space inciosed by the body portion 34, the flanges 40 and the casing 14, when the valve is traveling from its receiving position shown in the dotted lines in Fig. 2, to the position of discharge shown in full lines in said figure.

In order to give the valve a tight fit in the casing 14, packing rings 42 are clamped against the inner faces of the flanges 40 by means of rings or washers 44 and collars 46,

one of which is threaded upon the rod 32 and the other upon an extension 48 of the valve body 34. This extension is of suflicient length to engage one arm of an agitating lever 60 the other arm of which carries a plate 62 which the lever is designed to osciilate in the bottom portion of the can as movements are imparted to the lever by the valve, the lever being mounted by means of a pin 64 journaled at its ends in recessed lugs 66 carried by the bottom of the can.

In Fig. 2, I show the lever 26 pivoted at its lower end to the pin 30 and intermediate its ends to a link 22 by means of a pin 24, the other end of the link being pivoted on a pin 20 carried by a pair of lugs 18 formed on the upper side of the casing 14. In this form the extension 48 of the valve body 34 is suitably tapered to engage a socket 50 in the ground disk 52 formed on the end of the plunger 54 which slides through an opening in the cross bar 56 extending across the channel 6. The disk 52 is of a diameter adapted to close the opening into the casing 14 and serve as a check valve therefor, the plunger 54 having a slight loose play in its bearing'in the cross bar 56 so that the disk may be properly seated against the end of the casing and also have a bearing along the bottom of the channel 6. This plunger bar 54 is recessedat 58 to receive the end of the agitating arm 60.

In the operation of the faucet shown in Fig. 1, the valve remains normally in the position shown with the lever extending rearwardly toward the tank. In this position the cream may enter and fill the space between the flanges 40. As the lever 26 is moved outward the rear flange will close the opening into the space between said flanges before the forward flange opens communication with the nozzle. The valve now carries a quantity of liquid which is 'definitely measured by the space inclosed by flanges 40, casing 14 and body 34, of the valve and discharges the same as soon as this space is open to the nozzle by the forward flange 40 crossing the outlet through said nozzle, this discharge being permitted by the air vents 68 through the casing 14 opposite the nozzle. Immediately after the forward movement of the lever 26 to discharge the cream, this movement is reversed to restore the valve to its original position, and in this return movement of the valve the forward flange 40 carries with it all cream adhering to the inner walls of the valve casing in the vicinity of the nozzle, so that none of it may be allowed to drip out through the nozzle opening. At the same time that the lever is operating the valve in this manner. the extension a8 operates the agitator by first releasing the same to allow it to rock downward and afterward reengaging it to rock it back into original position.

In the operation of the faucet as shown in Fig. 2, the valve remains normally in the full-line position shown in said figure, with the lever 26 extending rearwardly toward the tank. On throwing the lever to the dotted line position the valve is forced to the rear so as to project into the channel 6 far enough to open the space between the -flanges 40 to the liquid in said channel as 7 shown by the dotted lines. Incidentally this movement of the valve brings the extension 48 into engagement with the disk 52 so as to force the latter and the plunger 54 backward to operate the agitator as represented by the dotted lines in said figure. Now as the lever is thrown back into original position, the valve advances toward its full line position, the weight of the plate 62 meanwhile forcing the plunger 54 and disk 52 forward to close further communication between the channel 6 and casing 14 as well as to relieve the valve from any pressure due to the liquid contents of the can. Thus a measured quantity of the liquid is discharged by the valve, as in the other mode of operation.

It will thus be seen that by applicants device a definite quantity of liquid is dispensed at each operation ofthe valve, and this operation can be carried on as fast as desired, the contents of the can being agitated for each operation of the valve.

The apparatus is especially desirable for restaurant use where cream is dispensed, as the waste of the cream by dripping out between operations iseflectually prevented by the action of the valve during the back movement in removing all of the cream adhering to the inner walls of the casing.

From the foregoing it will be apparent that I have produced a dispensing valve em-' bodying the features of advantage enumerated as desirable in the statement of the object of the invention, and while the above represents two embodiments of the same, I do not wish to be limited to the precise construction and arrangement shown but reserve the right to such changes and modifications as fall within the spiritLand scope of the appended claim:

The combination with an urn having an opening in its bottom, and a radial channel below and communicating with the opening in the bottom, a cylindrical faucet casing secured to the urn and communicating at its rear end with said channel, and provided with a vent opening and a faucet, a reciprocatory spool-shaped measuring valve fitting slidingly in the casing and adapted to enter the said channel, manually operable means for reciprocating said valve so that when in its rearward position itca-n be charged between its ends with the liquid from the urn and which when in its forward position will deliver said liquid to the spout, and a pivoted agitator mounted in the urn and provided with a portion depending into the channel and exerting a yielding forward pressure on the valve so as to yieldingly re-- sist rearward movement ofthe same and gravitate back to normal position when said valve is moved forward.

In testimony whereof, I aflix my signature, in the presence of two Witnesses.

HENRY D. KELLY.
