COFFEE URN.

Application filed November 28, 1922.

To all whom it may concern:

Be it known that I, EDWARD H. BAKER, a citizen of the United States, residing Seattle, in the county of King and State of l/Vashington, have invented certain new and useful Improvements in Coffee Urns, of which the following is a specification.

This invention relates to coffee-pots or codes-urns and more especially to strainer bag attachments thereof.

The object of my invention is the improvement of devices of this character to render the same more convenient and efficient in use and which will afford an excellent beverage with a relatively small quantity of coffee.

Other objects and advantages of the invention will appear in the following specification.

The invention consists in the novel construction, adaptation and combination of parts hereinafter described and claimed.

The accompanying drawing, shown partly in side elevation and partly in vertical sec tion, illustrates the invention applied to a coffee-urn.

in said drawing, the reference numeral 5 represents a cylindrical shell or liquid containing vessel of a coffe urn having a removable cover 6.

As shown, the cover 6 is provided with peripheral flange 7 which fits within the mouth of said vessel and above an annular shelf 8 formed or provided within the vessel.

9 represents a cloth bag secured to and depending from a metal ring 10 which is adapted to seat upon the shelf 8.

According to the present invention, I provide a rod 11 which extends through an aperture 12 in the center, preferably, of the cover 6 and is provided at its upper and lower ends, respectively, with enlarged portions such, for example, as loops 13 and 1d.

The lower end of the rod is connected by a string 15, or an equivalent, with the bottom of the bag and preferably through the medium of a tape or cord loop 16 secured to the bag.

17 represents a burner disposed below the bottom 18 of the vessel 5 for generating heat sui'iicient to efiect the boiling of a body of liquid, indicated by 19, contained in the vessel.

20 represents a sheet of asbestos or other suitable material which is removably in- Serial No. 603,761.

serted within the urn below the bottom 18 thereof when it is desired to prevent the liquid from boiling. 21 represents a drawoff faucet and 22 is a sight gage for indicating the quantity of liquid within the urn.

In practice, the bag 9 is attached to the rod 11 by means of astring 15 or the like and is inserted within the vessel to have the bag ring element 10 supported upon the shelf 8 of the urn. Water may be supplied within the vessel before or after the bag is inserted and is brought to a boiling point by employing the burner 17. Ground coffee is deposited in the bag. With the cover in place upon the vessel, the operator through the instrumentality of the rod 11 lowers and raises the bag to and from the full line posi tion to that indicated by dotted line 9 in the view to efiectreciprocation of the coflee grounds in the liquid.

Thus moving a body of ground coffee up and down in the water breaks up such body allowing the liquid to pass freely therefrom and produce a coffee beverage of a desired strength and with an excellent flavor.

During the making of the beverage the cover 6 serves to retain the steam and vapors within the vessel.

When the coffee beverage is completed the bag is preferably removed after dis'con necting the same as, for example, by cutting or untying the string 15.

With the bag removed the sheet 20 is inserted and the burner regulated to retain the beverage in a warm condition below a boiling temperature.

lVhat I claim, is,

The combination with a beverage receptacle having an annular shelf therein, a re movable cover provided with a central aperture and adapted to seat upon said receptacle, a cloth bag, and aring connected to said bag, said ring being arranged to seat upon said shelf below the cover for suspendin the bag within the receptacle, of a rod extending slidably through the cover aperture into said bag, and flexible means connecting the lower end of the rod to the lower end of said bag.
