SYRUP-PEBCOLATOB.

Specification of Letters Patent.

Patented Nov. 23, woe.

Application filed February 25, 1909. Serial No. 479,860.

To all whom it may concern:

Be it known that I, FRANK DE CLERO a subject of the King of Belgium, and a resident of the city of New York, borough of lvlanhattan, in the county and State of New York, have invented a new and Improved Syrup-Percolator, of which the following is a full, clear, and exact description.

This invention relates to syrup percolators such as used for dissolving sugar to form syrup which filters through into the syrup chamber. Such syrups are used as 'a basis for the flavoring syrups used in soda water and similar beverages.

The object of this invention is to produce a percolator of simple construction in which the sugar can be readily dissolved without coming into contact with the air, and from which the syrup may be readily withdrawn from the syrup compartment beneath.

A further object of the invention is to provide an improved filtering bottom for the sugar compartment.

The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claim.

Reference is to be had to the accompanying drawings forming a part of this Specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a vertical section through a syrup percolator constructed according to my invention, this section being taken on the line 11 of Fig. 2; Fig. 2 is a plan of the percolator; Fig. 3 is a section taken on the line 33 of Fig. 2, and illustrating the construction employed to make thecover of the percolator substantially air-tight; and Fig. 4 is a horizontal cross section through the percolator taken on the line 4l4 of Fig. 1, this view showing a portion of the filter bottom as broken away.

Referring more particularly to the parts, 1 represents the body of the percolator, which is in the form of a cylindrical shell disposed in an upright position. The upper edge of this body is formed with an annular fiange 2, upon which there is received an annular gasket 3. This flange is provided with wedge heads 4 constructed as shown in Fig. 3, and presenting horizontally projecting bills with inclined lower edges 5. The coverGof the percolator is made removable,

and is provided with openings 7 which cor respond to the wedge heads 4. In placing the cover in position it is lowered down so that the wedge heads pass through the openings 7, and the oor er is then rotated by means of a horizontal handle bar 8, so that the edges of the openings engage the inclined surfaces 5 and wedge the cover down on the gasket, as will be readily understood. In the lower portion of the body the inner side of the shell is formed with inwardly pro ecting lugs 9, and these lugs are adapted to support a filter bottom 10. This filter bottom is composed of a lower disk 11 and an upper disk 12. These disks are provided with a plurality of perforations 13, as shown. The lower disk 11 is provided with upwardly projecting posts 14: and these posts support the upper disk 12. On the upper side of the lower disk 11 a filter blanket or cover 15 of coarse fabric is applied, and the edges 16 are turned under the side edge of the disk, as indicated. A filter blanket 17 is applied to the under side of the upper disk 12, and the edge 18 of this blanket is turned over the upper edge of the upper disk, as shown. The upper disk 12 is provided with a handle 19 on its upper side by means of which it may be removed. The disks are large in diameter, so that when provided with their blankets they fit tightly within the shell so as to-substantially exclude the passage of a liquid at their edges.

On account of the posts 14: which may be three in number, as "shown, a filter space is formed between the two blankets, and in this filter space I place raw cotton 20, or a similar absorbent substance. The space in the body 1 below the filter bottom constitutes a syrup chamber or compartment 21, and the syrup which percolates through the filter bottom to this chamber can be removed by means of a faucet 22, as shown. In order to permit the air to enter the chamber 21 when the faucet 22 is open, I provide an air tube 23 which communicates with the upper portion of the chamber 21 and extends upwardly at the side of the body to a point near the upper extremity thereof, at which point the tube is bent downwardly and provided with an air check valve which will open on a slight reduction of internal pressure in the chamber 21, but which normally excludes the atmospheric air. This valve is most conveniently in the form of a ball 24 which seats in a small opening 25 in the lower extremity of the valve body, as indicated.

In using the percol-ator the portion of the body above the filter bottom is substantially filled with sugar 26, and water is then poured in until the percolator is substantially full. The water then dissolves the sugar and percolates slowly through the filter bottom 10. By excluding the air the syrup is prevented from becoming too thick, and the syrup which percolates through the filter bottom will be found to be highly fluid and clear. When the filter bottom is to be cleaned, access can be had to it by removing the cover, and by then removing the upper disk 12. The posts let can then be grasped and operate as handles to assist in removing the lower portion of the filter bottom.

Having thus described my invention, I claim as new and desire to secure by Letters Patent,

A percolator having a body with a filter bottom therein, a substantially air-tight cover for said body, the portion of said body beneath said filter bottom constituting a syrup chamber, a faucet for draining said syrup chamber, and an air vent having a check valve disposed near the upper end of said body opening communication between the atmosphere and said syrup chamber.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
