Int/enfor- HENRY CLAYTON BIETTE, 0F PITTSBURGH, PENNSYLVANIA.
PERCOLATOR.
Specification of Letters Patent.
Patented Dec. 14, 1920.
Application filed January 30, 1920. Serial No. 355,040.
To all whom it may concern:
Be it known that I, HENRY CLAYTON BIETTE, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have in vented new and useful Improvements in Percolators, of which the following is a specification.
My invention relates to percolators, and more particularly to the receptacle into which the ground coffee or other material is directly placed, preparatory to the forming of the brew.
The principal object of this invention is to improve the filtering or straining device of percolators, whereby the filtering medium is protected from injury or misplacement during use; and whereby the said receptacle may have its contents dischar ed with minimum loss of time and without the injury or displacement of the filtering medium. Another object is to provide the receptacle with such a shape that all the contents tend to flow toward the center thereof. Other objects appear hereinafter.
Referring to the accompanying drawing which illustrates the preferred form and construction of my invention, igure 1 is a vertical central section thereof; Fig. 2, a bottom plan View with a portion broken away; Fig. 3, a plan View of the filtering medium; and Fig. 4-, a plan view of the lower perforated disk.
The drawing illustrates only the filtering receptacle which is placed within the usual urn, or equivalent holder or dispenser of the brew resulting from the passage of hot water through the ground coffee orequivalent product in the receptacle. This receptacle is composed of sheet metal and preferably circular in cross-section, the upper portion 1 has the largest diameter and is connected to the lowest portion 2 by the downwardly tapering portion 3. The lower end of the portion 2 has the inturned flange 4 which forms the circumference of the central opening 5. To the lower side of the flange 4 is secured the metal strip 6 which slightly overlaps the opening 5, and forms a ledge or support for one edge of the lower perforated metal disk 7 which fits within the said opening.
On the upper face of the disk 7, I place a disk of filtering medium 8, which is preferably filtering paper though the medium may be a textile or other suitable material. While it is not essential, I prefer to have the combined thickness of the disk 7 and the medium 8 the same as that of the flange 4 so that the upper perforated disk 9 may lie on the upper face of the flange and hold or clamp the filtering medium 8 in its described position without liability of its becoming injured or displaced.
10 is a pivot or pin extending through the flange 4 and the disk at a point preferably opposite the ledge 6. The pin has the head 11 resting on the disk 7. The pin has thereon the button or look 12 which lies against the lower face of the flange 4 and has one side long enough to be swung beneath theedge of the disk 7 and hold it and the medium 8 securely in the positions shown and described. The pin has at its lower end a head 13 in contact with the lower face of the button. The pin and its heads hold the disk 9 and the button 13 in place, but these may obviously be so held by other means.
The inclined portion or shoulder 3 pro vides a seat to support the receptacle in the usual form of urn or percolating device. By
making this shoulder inclined downwardly the filtering process is improved since all the contents of the receptacle tend to flow toward the center, thereby making the brew uniform during filtration. When it is desired to supply fresh coffee or the like to the percolator, the receptacle is removed and inverted and the upper end jarred on a solid object to dislodge the grounds sticking to the interior walls and bottom thereof. This'can be done without any danger of injuring or displacing the filtering medium 8, permitting the receptacle to be recharged and returned to the urn or other holder with a minimum loss of time. This saving of time is particularly important in large restaurants where a slow process of emptying the receptacle would be an inconvenience to a large number of customers, and might result in a large loss of custom.
' I prefer that the medium 8 be paper hecause it can be used repeatedly without souring which occurs when textile bags are employed. The disk 9 not only protects and holds the medium 8 in place, but it also prevents any grounds passing into the brew 7 changes as come Within the spirit of the same and the scope of the appended claims.
I claim:
l. In a percolator, a filtering receptacle having an internal shoulder surrounding a bottom opening therein, a perforated sheet of metal lying on the shoulder, means preventing the removal of the sheet through the top of the receptacle, a filtering medium beneath the said sheet and Within the opening, a perforated removable disk beneath the said medium and Within the opening, a strip of metal secured to the receptacle and overlapping one side of the opening beneath the disk, and a latch carried by the receptacle and movable beneath the disk to lock it in place.
2. In a percolator, a filtering receptacle having an internal shoulder surrounding a bottom opening therein, a perforated sheet of metal lying on the shoulder, a filtering medium beneath the said sheet and Within the opening, a perforated removable disk beneath the said medium and Within the opening, a strip of metal secured to the receptacle and overlapping one side of the opening beneath the disk, a pivoted latch carried by the receptacle and movable beneath the disk to lock it in place, and a pin securing the said sheet and latch to the receptacle and serving as a ivot for the latch.
Signed at Pittsburgh, 21., this 29 day of Januar 1920.
IlENRY CLAYTON BIETTE.
