y1Perteirted 'June t, 1916.
Application led December 18, 1909.. Serial No. 533,766.
To all lwhoml t may concern:
rate-the solvent principal from solids and toV permit the ready discharge of the extract. In the accompanying rawing: Figure 1 is a vertical central section of a percolator embodying my invention; Fig. 2 a horizontal section online 2-2, Fig. l, with the top plate partly broken away; Fig. 3 a similar section on line 3-'3, Fig. 1, with the bell partly broken away, and Fig. 4 an enlarged section through part of the bottom, on line 4 4, Fig. 3. l
The percolator comprises essentially a cylindrical receptacle 10 having a sloping bottom 11. This bottom is provided on its upper side with radial ribs 12 separated by intervening radial slots. Each rib has a peaked top and parallel sides 13 below such top. In this 'way the radial slots between theribs are composed of.wide flaring upper channels 14 that o en into narrow lower ducts 15. rlhe latter, 1n turn, open at their inner ends into .a central well 16 of bottom 11, which is apertured as at 17. Into receptacle 10 is removably tted a bell 18 that rests upon bottom 11 and encompasses well 16. This bellV has a corrugated lower edge 19 that straddles ribs 12 and closes upper channels 14 at their inner ends, while leaving lower ducts 15 unobstructed. If desired, two or more bells of different diameters may accompany each receptacle 10, so that the operative size of the apparatus may be changed.' Near its top, receptacle 1() has an inner seat or shoulder 20 upon which is removably placed a top plate 21. This top plate is rovided with parallel corrugations aving ottom apertures 22. Shoulder 20 is corrugated as at 23 in conformity with the shape of top plate 21, so that the ,latter `is positively supported along its entire rim upon said shoulder.
In practice, the bell 'is fitted in position, the solid material from which the active principle is to beextracted is placed upon bottom 11 and plate 21 is properly seated. The liquid is now poured upon the top plate so as to descend dropwise from the apertured corrugations thereof into receptacle 10 around bell 18. The solid,while pack channels 14 will leave ducts 15 practi- 1n caIly unobstructed, so that the extract is free to flow alon said channels into well 16l to be finally dlscharged through openings 17 into a 'suitable receiving vessel.
I claim:
1. A percolator comprising a receptacle having a bottom which is provided with ribs having peaked tops and lower parallel sides to form intervening channels having flaring upper sections and communicating lower contracted ducts.
2. In a percolator, a receptacle having a 'bottom which is provided with a series of ooves and a communicating apertured well, combined with a bell havlngl a corrugated lower edge which engages t e bottom and yextends into the upper parts 'of the grooves while clearing the lower parts thereof.
3. In a percolator, a receptacle having a corrugated shoulder and' a bottomprovi ed with a series of grooves and a communicating apertured we l, combined with a bell encompassing the well, and with a corrugatedv and apertured top plate engaging the shoulder.
