CHARLES L. GARDINER, OF BINGHAMTON, NEW YORK, ASSIGNOR TO THE 1900 WASHER COMPANY, OF BINGHAMTON, NEW YORK.
WATER-FILTER.
To all whom it may concern:
Be it known that 1, CHARLES L. GARDINER, a citizen of the United States, residing at Binghamton, in the county of Broome and State of New York, have invented a new and useful Water-Filter, of which the following is a specification.
This invention relates to water filters and more particularly to a cleaning device for automatically removing any deposits of mud, slime and the like from the surface of the filtering medium.
The object of the invention is to provide a cleaning device in which the abrading member is automatically moved in contact with the filter stone as the latter is revolved by the action of the water, thus polishing the exterior surface of the stone and maintaining the latter in a clean sanitary condition.
A further object of the invention is to pro vide a guide ring or member operatively connected with the swing gate of the abrading member, said guide ring serving to insure a firm contact of the abrading member against the filter stone as the latter revolves and also serving to center the parts and prevent rattling or wabbling of the same.
A further object is to provide means for limiting the swinging movement of the abrading member so as to prevent the filter stone from being reduced .in size beyond a predetermined cross sectional diameter by the action of said abrading member.
A still further object of the invention is generally to im rove this class of devices so as to increase t ieir utility, durability and efficiency.
Further objects and advantages will apear in the following description, it being un- Eerstood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the ap ended claims.
11 the accompanying drawings forming a part of this specification: Figure 1 is a longitudinal sectional view of a water filter constructed in accordance with my invention. Fig. 2 is a top plan view of the same with the cover and Water wheel removed showing the cleaning element in normal or inoperative position. Fig. 3 is a similar view showing the position assumed by the cleaning element when the filter stone is revolved. Fig. 4 is a perspective view of the swing gate detached.

! Fig. 5 is a perspective view of the guide ring detached. Fig. 6 is a similar view of the segmental operating lever detached. Fig. 7 is a detail front elevation of a portion of the intorior of the casing showing the stop lug of the guide ring. Fig. 8 is a vertical sectional view taken on the line 88 of Fig. 7.
Similar numerals of reference indicate corresponding parts in all the figures of the drawin s.
The flltor comprises a casing or housing 5 having its u per portion off set to form an annular shou der 6 and thence extended laterally to produce acircumferential flange 7, which latter forms a support for the top plate or cover 8.
The top plate 8 is provided with a ni ple 9, the interior walls of which are threat ed for connection with a hydrant or other suitable source of water supply, said cover being rovided with a dependingflange 10 wl iich overlaps theflange 7 of the casing and is secured thereto by bolts or similar fastening devices 11.
Arranged beneath the top or cover 8 is a diaphragm 12 preferably curved to conform to the shape of the cover and spaced from the latter to form an intermediate chamber or compartment 13 adapted to receive the water from the hydrant or other source of supply.
The diaphragm 12 is provided with amarginal flange 14, which latter is interposed between theflanges gaskets 15.
Depending from the central portion of the diaphragm 12 is a lug 16 having a socket 17 formed therein and constituting a bearin for the upper end of a vertically disposedshaft 18.
Secured to and mounted for rotation with theshaft 18 is aporous filter stone 19 preferably cylindrical in shape and provided with an interior bore, spaced from the shaft, to form an intermediatewater receiving chamber 20, there being alongitudinal opening 21 formed in the lower end of theshaft 18 and communicating with thechamber 20 by means ofapertures 22, thereby to permit the discharge of the filtered water.
The upper end of theshaft 18 is threaded at 23 for engagement with aclamping nut 24, which latter bears against a plate orwasher 25 carried by the upper end of the filter stone.
Disposed in spaced relation to theplate 25 is a circular plate or disk 26 having its lower face provided with a lurality of radiating blades or pockets 27, W ich latter receive the impact of a stream of water issuing fromsuitable discharge nozzles 28 clependin from the diaphragm 12, there being suitable depressions 29 formed in theup er surface of the diaphragm at eachdepenc ing nozzle 28 so as to permit the ready flow of water from the chamber 13 through said nozzles to the blades of the water wheel. The circular plate 26 of the water wheel is provided with a centrally disposed opening the interior walls of which are threaded for engagement with the threads on theshaft 18 whereby rotary movement imparted to the water wheel will efiect a corresponding rotary movement of the filter stone.
The cleaning element forming the subject matter of the present invention comprises a swing gate orholder 30 having spacedlugs 31 extending laterally from one longitudinal edge thereof and connected by a rod orpin 32, which latter, is pivotally mounted incorresponding lugs 33 secured to or formed integral with the interior wall of the casing 5, as best shown in Figs. 1 and 7 of the drawing. The swinging gate or holder is provided with a vertically disposedseating groove 34 for the reception of anabrading element 35, the latter being preferably inthe form of a stick of carborundum or the like. The abradingmember 35 is clamped in position on the swinging gate or holder by means of aplate 36 havingtransverse slots 37 formed therein for the reception of screws orsimilar fastening devices 38, there being a strip of rubber or otheryieldable material 39 interposed between the abradingstick 35 and the adjacent wall of theslot 34 in order to form ayieldable seat for said abradingmember. Extending laterally from the opposite longitudinal edge of the swinging gate orholder 30 are spacedarms 40 and 41, which latter are curved to conform to, and normally bear against, the interior walls of the casing 5.
Slidably mounted on the annular shoulder 6 is a guide member orring 42 having spacedfingers 43 extendinglaterally from the inner face thereof and forming between them anelongated slot 44 adapted to receive the adj acent end of thepivot pin 45 of a segmental actuatinglever 46. One end of the actuatinglever 46 is provided with a vertically disposedstud 47, which enters therecess 43 of ahook 49 carried by and extending in a horizontal plane from the ring, as shown. The opposite end of thesegmental lever 46 is provided with a dependingsleeve 50 adapted to receive theangular extension 51 of a connecting rod orlink 52. The lower end of the ated power transmission member ordisk 54 provided with aperipheral flange 55 having anopening 56 formed therein for the reception of theangular extension 57 of the connectingrod 52 sot'hat when thefilter stone 19 is rotated by the water wheel the disk or attachingmember 54 will also be rotated and through the medium of thelever 46,rod 52 andguide member 42 actuate the abrading member to effect the cleaning of the filter stone.
As a means for limiting the inward movement of the swinging gate there is provided astop lug 58 which depends from the inner edge of theguide ring 42 and is disposed in the path of movement of theadjacent lug 33 so that when the filter stone is cut or worn away until the cross sectional diameter of the stone isof the same diameter as ti body of thedisk 54, thelug 58 will engage thelug 33 and thereby render the abrading element inactive.
In operation water is admitted to the chamber 13 through the nipple 9 and is spread over the surface of the diaphragm 12 in the form of a thin film, the liquid from the chamber 13 passing through thedischarge nozzles 28 and being directed against the blades 27 of the water wheel thereby to rotate the same. As thefilter stone 19 re volves thedisk 54 by frictional contact therewith, will be partially revolved thus exerting a pull on the connectingrod 52 and through the medium of thesegmental lever 46 andguide ring 42 move the swinging gate on itspivot 32 inwardly until theabrading strip 35 bears against the exterior face of the filter stone. As the filter stone wears away the swinging gate will be automatically forced inwardly so as to maintain thestrip 35 in constant contact with the filter stone. When the diameter of the filter stone is approximately the same as the diameter of the body portion of thedisk 54, thelug 58 will engage thelug 33 and prevent further inward movement of the swinging frame, in the manner before stated.
Attention is here called to the fact that the guide member orring 42 is slidably mounted on the shoulder 6 and not only-serves to insure a firm contact of the abrading stick or element against the filter stone as the latter revolves, but also serves to center the parts and prevent rattling or wabbling movement of the same.
It will of course be understood that the water will percolate through the filter stone into thechamber 20 and thence into thetube 21 where it may be drawn olf if desired through a suitable cock or turning plug provided for this purpose.
From the foregoing description it is thought that the construction and operation of the device will be readily understood by those skilled in the art and further description thereof is deemed unnecessary.
