all whom/'it may concern:

Be it known that'we, GEORGE E. SAVAGE and JAMES W. CHAPMAN, citizens of the United States, residing at Meriden, New Haven county, Connecticut, have invented certain new and useful Improvements in Per- -colators, of which the following is a full, clear, and exact description.

'Our invention relates to percolating-machines for making coffee by the method of dripping boiling water through the'cofeegrounds, and is designed for performing this operation rapidly.

The invention relates particularlyto urns adapted to be detachably secured to a base or standard and heated by analcohol-lamp.

The rinciples will be more clearly set forth in the olloWing descri tion. A

Fi ure 1 is a side e evation of an urn and stan ard, partially in section.4 Fig. 2 is a top plan v1ew of a segment of the standard, showing lugs` by which the urn is locked to the same. Fig. 3 is a bottom plan view of a segment of an urn, showing means for attaching the same to the standard.

1 is the base-ripng of the standard. 2 2 are its legs for supportlng the ring 3, in which the lamp 4 rests.

5 is a burner of any suitable design.

6 is the body or reservoir of the urn, in which the liquid is held.

7 is a receptacle for holding the coffeegrounds from which the beverage is made.

8 is the boiling or steam-generating chamber, having a suitable spigot or controllable v outlet 9.

10 is a cap for the boiling-chamber. This cap is preferably so constructed that the bolling or heating chamber 8 is insulated from the reservoir 6 by means of an annular air-space.

11 is an inlet to the boiling-chamber, and 12 is the percolatin tube or outlet.

The flame from urner 5 covers the bottom and sides of boiling-chamber 8, but is kept from the rest of the urn by flange 13, it belng desirable that the liquid in the reservoir 6 remain at a lower temperature than that in the boiling-chamber 8. It will be readily seen that by the above means the liquid .in chamber 8 is raised to the boilingpoint very rapidly. When the liquid in chamber 8 boils, it is forced through tube 12, percolating through the coffee-grounds in chamber 7 int'o reservoir 6, and in turn through o ening 11 into boiling-chamber 8, from whic it circulates as before until the bevera e has reached the desired strength.

The ase-flan e 13 is providedwith a locking-flange 14, W 'ch rests on the base-ring 1. The flange 14 has openings 16 in its bottom edge, and base-ring 1 is supplied with corresponding rojections 15. It will readily be Seen that w en openings 16 are set over projections 15 and the urn turned until the openings are out of alinement with the rojections the urn will be securel attachedp to the base.I The flange 13 acts, tfierefore, not only as a base for the urn, but shields the reservoir, and thus hastens the percolator action.

cured adjacent the caplat the top of the heating-chamber and at t e bottom of the main li vuid-reservoir or-body portion.

at we claimisf 1. In a percolator, a liquid-reservoir, a receptacle for holding the grounds, a heatingchamber having lateral walls exposed to the flame, a cap having an inlet andan outlet, and a base-flange secured at the top of and extending laterally of said chamber.

2. In combination, a percolator-urn having a liquid-reservoir, a rece tacle for holding) the grounds, a heating-c amber having su stantially vertical walls, a controllable outlet from said chamber, a cap having an inlet and an outlet a flaring base-flange secured adjacent the operative position of said cap, a standard for supporting said percolator, and a lamp.

8. In a percolator, a body having a heating-chamber, a cap `for said chamber, and a laterally-extending flange secured at the bottom of the main portlon of the body for shieldingit from the heat of the llame.

4. In a ercolator, a liquid-holding reservoir or bo y, a receptacle for grounds, a heatin -chamber, a ca therefor,` a percolatortu e, and a baseange extending laterally from the top of said heating-chamber adjacent the operative position of said cap.
