PERCOLATOR.
Specication of Letters Patent.
Patented May 22, 1906.
Application filed August 31,1905. Serial No. 276,524.
To all whom it may concern.' 'l
i Be it known that I, GEORGE E. SAVAGE, a citizen of the United States, residing at Meriden, New Haven county, State of Connecti- A cut, have invented certain new and useful Improvements in Percolators, of which the following is a full, clear, and exact description.v
My invention relates to percolators for automatically making what is termed dripcoffee, and particularly to an improved contruction for increasing the speed of operaion.
The linvention is designed particularly for that type of coffee-pot which is adapted to be placed upon the stove.
The principles of the invention will be more clearly understood from an inspection of the accompanying single sheet of drawings and the following specification.
Figure 1 is a vertical projection and vpartial section illustrating the parts of the coffee-pot embodying the improvements of my invention. Fig. 2 shows the member forming the top of the steam-generating chamber with an inlet and outlet.
1 indicates the body ofthe coffee-pot.
2 is Ia suitable handle.
3 is a suitable spout.
4 is the receptacle for holding the coffeegrounds or other ground material from which the beverage is to be drawn.
5 is a cover for the receptacle of suitable form and held in place in a convenient manner, preferably as described in my application, Serial No. 240,854.
In the bottom of the fluid-holding body 1 is the heating-chamber, having a substantially vertical wall 6. This chamber is of considerably smaller diameter than the body of the receptacle and is adapted to inclose only a small quantity of liquid, so that the heat of the stove will quickly raise its temperature to boiling-point and'start the operation ofthe percolator.
7 is a cover or bell for the heating-chamber, which is preferably formed with double walls.
8 represents a downwardly-projecting collar which has a suitably-sized air-chamber for better insulating the fluid above the steam-chamber.
9 is a flange carried by the cover, which is adapted to rest upon a ledge or shoulder 10 of the body.
The outer wall ofthe collar 8 frictionally engages the vertical wall 6 of the body and closes the chamber.
11 is a recess in the bottom of the cover 7 formed by the depending collar 8.
12 is a tube forming an inlet to the heatingchamber from the fluid-holding body 1.
13 is the outlet from the heating-chamber, which is commonly termed the upercolatortube. This tube extends up to the top of the ot and has a series of outlet-perforations in t e tube member 14.-
' In operation the heat of the stove boils the water within the heatin -chamber 11. The steam thus generated forces the fluid up through the tube 13, from which it is sprayed at the top and drips down through the coffee, forming thebeverage.
'It is essential to the operation of the device that the main body of fluid remains at a substantially lower temperature than the fluid in the heating-chamber. For this urpose I have provided a base-ring 15, ormed of heavy metal and secured to the bottom of the pot by an upturned collar 16. I prefer to spread or expand the bottom 17 out, as shwn at 18, to more securely unite the parts. The considerable body of metal in this base-ring insulates the body of the Huid-holding receptacle from the heat of the stove to a sufficient degree to prevent the main body of liquid from being raised to the boiling-point. To assist in this insulation, I have constructed a pot so that there is always an air-space of considerable size between the base-ring 15 and the bottom of the laterally-extending body 1. While the bottom of the heatingchamber is of a small size, the base-ring 15 conducts its heat to the side walls, and thus provides additional available heating-surface. The base-ring extends over such an area as to make the coffee-pot perfectly stable and prevent its being tipped over. The advantages of this construction will be apparent to those skilled in the art.
What I claim is- 1. In a percolator, a fluid-holding body having an integral bottom portion forming a relatively small heating-chamber at the base, a cover member forming the top of the heating-chamber, a percolator-tube connected to f the cover, said cover having an inlet discharging close to the bottom for the passage IOO of iluid from the body to the heating-chamber, and a base with a ring formed separately from the bottom of the heating-chamber and laterally surrounding and secured in intimate 5 contact with the outer side Walls ofthe heatsmall eating-chamber, a cover for the heating-chamber having an inlet and an outlet, and a separately-formed base-ring providing an extended base and vertically insulating the body, the bottom of the heating-chamber being expanded outwardl to aord a secure and intimate union Witht e base-ring. l
3. In a percolator, a fluid-holding body having a bottom With an integral portion forming the bottom and side Walls of a heatl ing-chamber, a cover forming the to of the heating-chamber, and having an i et-pas- 2 5 sage discharging close to thebottom or the l i chamber, a percolator-tube leading upfrom said cover and a base With a ring formed separately from the bottom of the heating-chamber and surrounding and secured in permanent intimate contact with the side Wall of the heating-chamber, and extending beneath the laterally-extending bottom of the body. 4. In a percolator, a fluid-holding body having a bottom ortion forming a heatingchamber, a cover orming the top ofthe heating-chamber, and having an inlet-passage, a ercolator-tube secured to the cover and a ase with a ring formed separately from the bottom of the heating-chamber and surrounding and in intimate contact with substantially the entire' side Wall of the heatingchamber, said ring forming an extended base and having its lower supportin -surface substanti ally on a plane with the ottom of the heating-chamber and substantiall below the plane of the bottom of the Huid-ho ding body.
