WILLIAM n. WILEY, o F FREDONIA, NEW YORK. Letters Patent No. 68,675, dated September 10, 1867.

IMPROVEMENT IN FILTERS.

'l'O ALL WHM IT MAY GONOERN:

Be it known that I, WILLIAM H. WILEY, of Fredonia, in the county of Chautauqua, and State o t New` York, have invented a new and improved Water-Filter; and I do hereby declare that the following is a full and exact description thereof, reference being hadl to the accompanying drawings, making a part of this specification, in whiehi lFigure I is a vertical section, and

Figure IIis a horizontal section inplan. l

The nature of this invention consists in making a hollow cylinder', of pottery or other porous material, in combination with an inverted metallic cup, of, larger diameter than the porous cylinder, and forming ,a waterchamber around the porous cylinder from which the external airis excluded.

This improvement is designed more particularly to be used inwells and cisterns from which water is to be elevated by means of a pump, but it is applicable for commonnse in the house as a filter for drawn water.

In the accompanying drawings letters of like name and kind refer to like parts in each of the figures. i,

A represents a cylinder, of pottery or porous ungla'zed earthenware, having an internal water-chamber,

` a. B represents un unporous metallic cup, of larger'diameter than the porous cylinder, which is inverted and placed on the upper end of the porous cylinder, forming Va,water'-chamber, B', around the upper part of; the porous cylinder, from which chamber thc external air is excluded. Connected withthis cup, and permanently attached thereto. is a short. perforated tube, C. 4This 'tube projects downwardly from the centre of the cupinto the water-chamber, a. Its perforations or side holes are shown at c1. The Vupper end of this tube has a. head or shoulder, c2, which rests upon the disk of the cup or on the top ofthe porousv cylinder. An innerscrew# thread is cut in each end of this tube for 4'the purpose of forming a screw connection with the eduction tube D and with the supporting` bolt E. The supporting bolt E passes through the lower end of the porous cylinder and screws into the lower end of the tube C, as shown lin the drawings, and serves to hold the porous cylinder rmly in place and in connection'with the inverted cup B and eduction tube D. A bottom metallic plato is shown at F, which tits closely on to the lowerend oi'. the porous cylinder, ndis for the purpose-of protecting it and for preventing the water from percolating through the end of .the cylinder. This plate may be dispensed with and that end of the cylinder glazed if preferred; or when made thick, as shown in the drawing, the plate and the glazing may both be dispensed with, and the water allowed to lter through the end as well asV the sides into the chamber a; but I-prefer to use the plate or to glaze the end of the cylinder. p

When this device is used in wells or cisterns it is connected with the eduotion tube, and by thattube lowered into the well or cistern, und then, by means of a. pump which is connected to the eduction tube C at the surface, the water is pumped clear and-pure from -thc chamber a', the water being strained or filtered in passing` through the porous body of the cylinder A. It will pass in snfiiciently to supply the pump. The invertedcup- B forms an air-tight chamber around the upper part of' the cylinder, which prevents air from drawing into the eduction tube, andrinsures a complete and perfect action of the pump. If need be, this ilter can be raised from the well or cistcrn at anytime, by means of the eduction tube, for cleaning or repairs, and easily replaced by the same means. Theeduction tube will hold it in place in the well or cistern, or additional stays may be applied if necessary. -This device may also be used in small vessels in the house for 'ltering water for'ordinary Vuse after it hns been drawn from the cistern, reservoir, or well. It is simple, cheap, durable, andeie'ctive as a filter.

What I claim as my invention, and desire to secure by Letters Patent, isf- A water-filter havinga hollow, porous cylinder, A, in arrangement with the'inverted cup B, for the purpose and substantially as described.
