WATER-FILTER.

SPECIFICATION forming' part of Letters Patent No. 611,426, dated September 27, 1898.. Application tiled November l2, 1897. Serial No. 658,309. (No model.)

- Be it known that we, DWIGHT J. Buss and EDWARD J. RICHMOND, citizens of the United States, residing at Carthage, in the county of Jasper and State of Missouri, have invented certain new and useful Improvements in Water-Filters; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. ,l

Our invention relates to a novel form of filter, and the object is to provide a simple, inexpensive, and effective filter for general use that shall be automatically cleaned each time a quantity of water is drawn from the filter.

To these ends the invention consists in the construction, combination, and arrangement of the several parts of the device, as will be hereinafter more fully described, and particularly pointed out in the claims.

The accompanying drawings show our invention in the best form now known to us; but many changes in the details-might be made within the skill of a good mechanic without departing from the spirit of our invention as set forth in the claims at the end of this specication.

In the accompanying drawings the saine reference characters indicate the same parts.

Figure 1 is a perspective view of our improved filter. Fig. 2 is a front elevation with a portion of the casing removed to show the cleaning device. Fig. 3 is a vertical section.

' Fig. 4 is a horizontal section on the line 4 4 of Fig. 3. Fig. 5 is a similar View 'on the line 5 5. Fig. 6 is a vertical section through the valve-casing, taken at a right angle to that shown in Fig. 3. Fig. 7 is a detail view of the plug cock or valve removed from the casing. Fig. 8 is a detail view of the spring-pawl.

1 represents the cylinder or casing, and it may be of any size or dimensions to correspond to the capacity required. Its closed top is formed with a central externally-threaded stuffing-box 2 to receive the packing-gland 3, and its lower edge is provided with an annular flange 4, by means of which it is secured to the hollow base 5 by the bolts 6 6.

7 represents a central tubular shaft, its upper end extending through the stuffing-box 2,

and on this projecting end is fulcrumed the crank-handle 8 by means of the bolt 9, .so as to permit a limited vertical movement of the outer end of said handle. The lower'end of the tubular shaft 7 terminates in a taper plugcock 10, which has a bearing in the valvecasing 12, which may be formed integral with the base 5L This casing 12 is provided with an inlet-pipe 13 and an outlet-pipe 14, which terminate in a gooseneck 15 for the discharge of the filtered Water.

16 represents a-radial passage in the plugcock, which is alined with the inlet-pipe 13, and it communicates with the vertical passage 17 in the tubular shaft 7, and the upper end of the passage 17 terminates in a series of radial orifices 18 18.

19 represents an annular disk resting upon the annular shoulder 20 of the plug-cock', and 21 represents a packing ring or gasket to form a joint between the disk 19 and the lower end of the filtering-cylinder 22.` A similar gasket 23 is located between the upper end of said cylinder 22 and the disk 24, which shclamped to the upper end of the cylinderby' the nut 25, engaging the threaded portion 26 of the shaft 7. 4

27 represents a hood or bonnet which encompasses the upper end of the shaft above the porous cylinder, and it serves to deflect the water from the orifices 18 and distribute it evenly over the outside surface of the cylinder.

28 represents a radial passage in the plugcock, which is alined with the outlet-pipe 14, and it connects with a vertical passage 29, which in turn communicates with the interior of the porous cylinder.

30 represents an air-chamber depending from the disk 24, so as to occupy the space in rthe upper end of the filtering-cylinder.

31 represents a curved plate fixed on the upper end of the outside of the casing 1, and it is provided with two stop- notches 32 and 33, located in the path of the outer end of the lever-handle 8. Y

34 represents a spring-pawl fixed on the upper face of the base 5, and its free end is adapted to engage a notch orrecelss` 35, formed in a fiange 36, depending from and extending part way around the lower disk 19, so as to permit the porous cylinder to be rotated in IOO one direction and prevent it being rotated in the opposite direction.

37 represents the Waste-pipe, the upper end of which terminates in a valve-seat 3S, located in the base 5, and 39 represents a valve pivoted on one end of a lever 40, fulcrumed in the bracket 41, fixed to the base. The opposite end of the lever 40 projects upwardly and into the path of the depending iiange 36, so that in rotatingthe porous cylinder the :Iiange 36 presses the free end of the lever 40 down, thereby raising the valve and permitting the water in the casing to escape.

41 represents a vertical shoe secured to the ends of two parallel springs 42 42, fixed at their opposite ends to the inside wall of the casing, and 43 represents a strip or bar of sandstone or similar abrading material held in the shoe and arranged to be held in contact with the outer face of the porous cylinder. Ay scraper-bladev 44 is pivoted to the shoe 4l, and its edge is held in contact with the cylinder by means of the spring 45.

The operation of the filter is as follows: When the lever 8 rests in the notch 32 in the plate 31, the feed-water is on and passes up through the tubular shaft 7, out through the orifices 13, and under the hood 27, which deflects it over the outside of the poronscylinder, through which it passes, and compresses the air in the air-chamber 30, and if the lever 8 is now raised from the notch 32 and turned to the right the feed-water is turned off, and the water inside of the porous cylinder is forced outwardly through the walls of the porous cylinder, and at the same time the sandstone bar 43 and the blade 44 remove the slime or sediment from the outside of the porous cylinder, and the flange 36 raises the sediment-valve 39 to allow the escape of the refuse. The lever-handle may now be turned around and left to rest in the notch 33, in which position. both the inlet and the discharge pipe are open and a continuous flow of filtered Water is discharged at the gooseneck-outlet. When sufficient filtered Water has been discharged at the outlet-pipe, the lever is movedforward to the notch 32, which cuts off the discharge, but leaves the inlet on. Consequently the filtered water accumulates in the porous cylinder until the air-pressure in the air-chamber counterbalances the waterpressure in the inlet-pipe.

Having thus fully described our invention, whatwe claim as new and useful, and desire to secure by Letters Patent of the United States,

1. A filter comprising the cylinder 1, provided With the valve-casing 12 having the Water inlet and outlet in combination with the central tubular shaft 7, provided with the radial orifices 18, and the plug-cock 10 having corresponding inlet and outlet passages, the concentric porous cylinder 22 and the airchamber 30, and means, substantially as set forth, for simultaneously operating said plugcock and porous cylinder, as and for the purpose set forth.

2. A filter comprising the cylinder 1, provided With the valve-casing 12 formed with the inlet 13 and the outlet 14, the retainingspring 34, and the notched plate 31, in combination with the vspring-actuated scraper 44 and abrading bar 43; the vertical tubular shaft 7 provided with the orifices 1S, the plugcock 10 fixed to the lower end of said shaft, the iianged disk 19 and the hand-lever 8, pivotally secured to said shaft and adapted to engage the notched plate, the porous cylin der 22 and the connected air-chamber 3() removably secu red to said shaft, concentric with the cylinder 1, substantially as described.

In testimony whereof We hereunto affix our signatures in presence of two Witnesses.
