IVIICHAEL C. GESKEY, OF LINCOLN, ILLINOIS.

SEWER CLEANER.

Application filed February 2, 1924. Serial No. 690,316.

To all whom it may concern:

Be it known that I, MICHAEL C. GEsKEY, a citizen of the United States, and resident of Lincoln, in the county of Logan and- State iof Illinois, have invented certain new and useful Improvements in Sewer Cleaners, of which the following is a specification.

My invention relates to improvements in devices which are adapted to be vdrawn through sewers or like conduits and to effect the cleaning of suchconduits and it consists in the combinations, constructions and arrangements herein described and claimed.

An object of the invention is to provide an efficient device of the character described which is of simplified construction and Which affords facilities for dislodging' material from the inner wall of a sewer or like conduit through which the device is drawn as well as for effectually breaking up and ejecting material from the sewer or like conduit. v

A further object of the invention is to provide a device of the characterdescribed which comprises detachable cleaning and guide members which may be replaced by like members of suitable size to adapt the device for use in cleaning a conduit of any given size.

Other objects andadvantages will be apparent from the following description, considered in conjunction with the accompanying drawings, in which- Figure 1 is a longitudinal vertical section through a portion of a sewer conduit, showing a cleaner embodying the invention disposed therein,

Figure 2 is a section along the line 22 of Figure 1, V

Figure 3 is a section along the line 3-3 of Figure 1, and v Figure 4- is a fragmentary longitudinal vertical section through the cleaner. y

In carrying out my invention, 1 provide a tubular body 1 which is closed at its forward end as indicated at 2 and is adapted at its rearward end for connection with a coupling 3 whereby the tubular body may be attached to a hose 4 or like conduit for a purpose which will presently appear. I

The tubular body 1 is provided adjacent to its forward end with a pluralityjof lat eral nipplesor pipe connections 5. In the embodiment of the invention illustrated in charge ting edge 15 the drawings, two of the nipples'5 areprovided, one being directly above'the other.

Dischargepipes 6 are connected with the nipples 5 and preferably havethe form clearly shown in the drawings, each dispipe. 6 extending radially outward from the tubular bodyl 1"for partof its length, thenbeing bent to extendforwardly in spaced relation to the tubular body 1 to a plane located slightly in advance of the forward end of the tubularbody 1 and finally being bent obliquely outward as at 7 and provided "at its free or forward 'end with one or more discharge nozzles 8, the upper discharge pipe preferably being provided with one discharge nozzle Sand the lower discharge pipe being providedwith three of the nozzles 8.- l 1 t i 1 The tubular body 1 has a flange 9 located in advance of the vnippleso near" the forward end of the tubular body. An attaching or carrying disk 10 is mounted on the tubular body 1 in advance of the fiange'9 and secured adjacent to its inner endto the flange 9 by bolts 11. an annular cutter or scraper plate 12 which obviously'may be formed of two or more pieces is removably secured adjacent to its inner: edgeto the attaching plate 10, asbv means of nuts and bolts such as indicated at 13, the inner edge portion of the cutter plate being clamped against the forward face of the attaching plate 10 and adjacent to the outer edge of the latter, the cutter'plate'12' being held in concentric relation to the" tubular body 1. The cutter plate 12'curves forwardly at its outer edge at 14 and the forwardly curved outer edge portion thereof tapers .in thickness so that the cutter plate has a relatively sharp forwardly projecting outer edge, as

indicated at 15 and as best seen in Figure 4:.

The cutter plate 12 has openings 16 through which the pipes6 extend, whereby the-nozzles 8will be positioned slightly in advance of the cutter plate 12 and will discharge outward in a plane oblique to and slightly in advance of the plane of the 'cutunners or guides 17 adapted for sliding contact with the inner wall of a sewer"conduit or like tubular member are removably secured by fastening devices 19to-the:outer end portions of radially extending bracket arms 20 which are carried by clampsrQl. The latter are'mounted on the tubular body 1 and each clamp 21 preferably comprises two cooperative sections adapted to embrace the tubular member 1 and being provided with pairs of ears 22 apertured to receive bolts 23 for connecting the clamp sections together and for holding 'the clamp sections in embracing relation to the tubular body 1. In the embodiment of the invention illustrated ,in the drawings, each of the clamp sections has two radially extending arms 20 and two of the clamps 21 are mounted on the tubular body 1, the respective clamps being spaced a considerable distance apart along the tubular body 1 and each of the runners 17 being'attached adjacent to one of its ends to anarm 20 of one of the bracketsand being attached adjacent to its opposite end to the corresponding arm 20 of the other clamp.

'With this arrangement, the runners 17 are spaced equi-distant from the longitudinal axis of the tubular body 1 and also are located substantially equal distances from one another. The tubular body 1 has the forward end thereof provided with an eyelet or hook 2 1 which is located centrally of the end 2 of the tubular member and to which a draft element 25 is attached. The latter preferably is a flexible cable.

A suspension cable 26 isattached at 27 to the tubular body 1 adjacent to the rearward end of the latter and is provided with straps '28 which encircle the hose 4t and tend to support the latter.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. The hose 4 is adapted to supply water or other cleaning fluid under pressure to the tubular body 1. The cable 25 may be attached to a Windlass or like device for pulling the cable 25 and therefore the device through the sewer conduit 18 or through any portion of such conduit, as for instance from one manhole with which the sewer conduit is in communication to the next manhole. As hereinbefore stated, the'cutter plate 12 and the slide .mem- 'bers 17 are removable as are the clamps 21 so that clamps having arms 20 of suitable lengths to position the slide members 17 in sliding contact with the inner wall of a conduit of any given size and a cutter plate of :a suitable width in respect to the conduit 18 of any given diameter may be attached to the tubular body 1 at any given time. The device therefore may be used to effect the re- :moval of material from sewer conduits of various diameters.

When the device is drawn through a sewer conduit 18 in the manner described, the cutting-edge of the plate 12 will be positioned close to the inner wall of the conduit and will scrape or dislodge all material from the inner wall'of the conduit and deflect the dis lodged material inward. The water passing under pressure from the hose 4 in the tubusure fluid supply lar body 1 will be discharged through the nozzles 8 slightly in advance of the point of contact and will strike the material ad hering to the inner wall of the conduit just before such material would be engaged by the forwardly moving cutter blade. Such material therefore is loosened or broken up before being struck by the forwardly moving cutter blades and therefore no very great resistance to the progress of.the device is interposed by the material within the conduit. Such material either is washed through the conduit ahead of the device or is pushed through the conduit by the device to any suitable place where it may be collected and removed from the conduit or otherwise disposed of.

Obviously, any invention is susceptible of embodiment in forms other than that illus trated :in the accompanyingdrawing, and I therefore consider as my own all modifications and adaptations :of the form of the device herein described as fairly fall within the scope of the appended claims.
