MACHINE FOR CLEANING FILTER-BEDS.

No. 873,0 1 O. Specification of Letters Patent. Patented Dec. 10, 1907.

Application filed April 6. 1904. Serial No. 201.933.

T 0 all whom it may concern: Be it known that I, HIRAM W. BLAISDELL,

Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Machines for Cleaning ,FiltenBeds; and I do hereby declare the following to be 'a full; clear, and exact description of the invention, such as will enable others skilled in the art to j which it appertains to. make and use the same.

This invention relates to means for cleaning material and particularly to machines for cleaning filter beds; and some of the objects of the invention are to provide a simple cheap and efficient machine of this character.

Another object of theinvention is to provide means for operating upon the surface of filter beds so constructed as to automatically follow the ins ualities or unevenness in the surface of the lter-bed.

It is also an object of this invention to provide means for operating upon the entire width of the filter bed at one time or to provide cleaning means extending entirely across the filter bed, and constructed to be With these, and other, objects in view the invention consists essentially in the construction, combination and arrangement of parts substantially as more fully describedin the following specification and illustrated in the accompanying drawings, forming part of this application, in which Figure l is a front elevational view of one tional View of the same; g; 3 is a top lan view, thereof, partly broken away; and l igs. 4 and 5 are enlarged detail views of one form of shoe employed.

Similar characters of reference designate corresponding parts throughout the several views.

Referring to the drawings, and particularly to the construction illustrated in Figs. 1, 2 and 3 thereof, the reference character 1 designates a portion of the walls of one or more filter beds, which may be arranged in any desired manner and may be of any preferred size and formation.

On the walls 1 are secured trackrails or ways 2, whereon travel the supporting wheels hop er \by the 3, of atraveling structure or bridge 4, and a propelling shaft 5 is formed on, or connected with, one set of said wheels, and preferably carries fast and loose pulleys 8 and 9 respectively connected by a twist belt 10, with a pulley 11, on a clutch shaft 12, carrying a fast pulley 13 attached by a belt 15, withthe driven pulley 16, of a centrifugal or other pump 17, substantially asshown.

The pump 17 is preferably provided with a discharge pipe 18, adapted to empty into the or receiver 19, the-material elevated ump, as subsequently explained, and an out et pipe 20 is preferably connected with the receiver 19, so as to discharge the Y liquid therefrom into a gutter or conduit 21, formed in or upon the wall 1, essentially as shown. i

An endless elevator 22 is desirably mounted in the receiver 19 to remove therefrom the solid matter conveyed therein by the action of the pump and the elevator is desirably driven through the mediation of gearing 23, a band wheel 24, belt 25 and pulley 26 on the drive shaft of a motor or engine 27, Figs. 1 and 3. I p

A motor or engine .28 is connected with a band wheel 29 on the clutch shaft 12, which carries a fast pulley 30, connected by a straight and twist belt 32 and- 33 respectively, with loose pulleys 34 and 35, on the prgelling shaft 5, before mentioned.

y means of the construction just describedv the bridge ma be progressed in a forward or backward irection according to whether the straight belt 32 or twist belt 33 is on the fast pulley 14 on the propellim shaft5 of the bridge.

The band wheel 29 is preferably mounted on. an intermediate section 36 of the clutch shaft 12, and is desirably connected alternately with one or other end of said shaft by means of clutches 37, one whereof connects the intermediate driving section 36 with the left hand end of the clutch shaft, carrying the pulley 30 and beltedv to pulleys 34 and 35 on the propelling shaft; whereby the bridge is alternately progressed rapidly in either direction.

When the other clutch is thrown into engagement, the right hand end of the clutch shaft is driven, thereby actuating the pulley 11, thereon, which is belted to a fast pulley 9 on the pro )elling shaft 5, to progress the bridge at a s ow rate; and the rotation of this end of the clutch shaft operates the fast pul ley 14 thereon, belted to the pulley 16'on the shaft of a centrifugal pump 17, as before explained. g

Channel irons or guides 38 are preferably vertically in or adjacent to thebridge 4 and movably mounted therein are frames or hanger members 39, connected with a pipe or device 41, with which communicates a pipe tube 42, connected with the pump 17, substantially as shown.

Formed on, or connected with, elevating 4, whereby the material enters the section,

passes therethrough and out by way of a flexible connection with the pipe 41; and material and fluid alsoenters' the sections 44 through the openings or inlets 51, in the upper portion thereof, Fi s. '3, 4 and 5.

T e operation of t e invention will be readily understood from the foregoin description when taken in connection'wit' the accompanying drawings and the following explanation thereof.

The motor 28 is started, thereby imparting motion. to the intermediate drivin section 36 of the clutch shaft 12, and the eft hand clutch being in engagement, the twist belt 33 is operated to actuate the pro elling shaft 5 and progress the bridge in a or'ward direction u'ntll the apparatus shall have reached the lace of o eration, whereupon the left han clutch is't own out of engagement and the right hand clutch is thrown into engagement, thereby actuating the belt 15 connected with the centrifugal ump, and, at the same time, operating'the elt 10 to progress the traveling structure automatically during the operation of the apparatus.

The pump being ut in operation, and the traveling structure eing automatically and slowly progressed, the cleaning device is caused to travel over the bottom of the filter bed,- and conform with the inequalities or undulations thereof by the play between the parts, and the deposit or crust on the filter ed is removed therefrom by the action of the sections 44, into which the forei n matter and fluid is taken, and from which-t e same is removed through the flexible connection 50, horizontal pipe41 and the vertical pi e 42 to the centrifugal pum ,from whence t e same is discharged throng the pi e 18 into the receiver 19, provided with a ischarge pi e 20 for the liquid and theelevator 22 to disc arge the solid material from .the receiver, substantially'as illustrated in Fig. 1 of the drawmgs.

. By reason of the construction of meansfor elevating and dischargin the material, the

entire surface or width 0 a filter bed can be treated in one-operation and the construction of the cleaning device in sections per-f melts the devices to more readily conform to v the me ualitles or unevenness 1n the surface of the lter bed, while the movable connection of each section affordsa limited independent motion, and the upwardly deflected extremity of each section acts as agage for regulating the o eration of the section.

After a filtered shall have been cleaned,

and it is desired to move the'traveling structure from one filter bed to the other, it is only necessary to operate the elevating shaft 52, carrying pinions 53 engaging racks 54 on the frames 39, until the cleaning devices shall I have been elevated a sufficient distance to clear the walls of the filter-bed, as will be readily understood by those skilled in the art to which this invention appertains.

It is not desired to limit or confine this invention to the specific construction, combination and arrangement of parts herein shown and described, and the right isreserved to make all such changes in, and modifications of, the same, as come' Within the spirit and scope of the invention.

Claims 1. A machine for cleaning filter beds comprising a support adapted to travel lengthwise the filter bed, suction means for elevating and discharging material, a series of independently operating scrapers arranged end to end entirely across the filter and ada ted to scrape material from the surface of the filter bed in the direction of travel of the support and a connection between said scraper means and said elevating and discharging means.
