To all whom it may concern PATRICK J. HEALEY, or JERsE cI'rY, NEW JERSEY.

SEWER-CLEANING DEVICE.

Be it known that I, PATRICK J. HEALEY, a citizen of the United States, and a resident 'of Jersey City, in the county of Hudson and State of New' Jersey, have made and m-' vented certain new and useful Improvements in Sewer-Cleanin Devices, of which the following is a specification.

My invention relates to sewer cleaning devices designed to remove such accumulation of solid material as may have collected within asewer, or rather in a section thereof between two manholes, the invention having particular reference to that type or class of sewer cleaning devices in which a'bucket is drawn through the sewer by means of a suitable rope and during which it scoops up a load of the material to; be removed, after which the same is elevated to" the surface of the ground through a suitable manhole; an example of which class of devices is shown in my Patent No. 775,677, for machine for cleaning sewers, patented November 22, 1904:, and of which device the sewer cleaning mechanism to which this present application relates is an improvement.

Theobject of the invention disclosed and claimed herein is to provide a sewer cleaningmechanism or device of the class'above referred to which may be operated entirely from one end of the sewer or section thereof to be cleaned. v A further object of my invention is to provide improved means for accomplishing the dumping of the contents of the bucket employed after it has been elevated to the surface of the ground; and further objects of my invention will appear in the following "description, wherein-the particular features thereof are pointed o-utat length.

With the above and other objects in'view, my invention consists in the improv'dsewer cleaning device illustrated in the accompanying drawings, described in the following specification, and particularly claimed, and in such variations and modifications thereof as will be obvious to those skilled in the art to which my invention relates.

In the drawings accompanyingand form- .ing a part ofthis specification, and wherein the preferred embodiment of my invention is illustrated F gure 1 is a view showing my improved sewer cleaning device installed in a section of sewerto be cleaned; and

Specification of Letters Patent.

Patented Aug. 19, 1919.

Application filed February 1', 1919. Serial No. 274,427;

2 is a view upon a larger scale illustrating my invention and in which certain "portions thereof are shown in two positions,

in order that the operation thereof may be better explained.

- Referrlng now to the drawings, the reference numeral 5 designatesa section of sewer to be cleaned, and 6 and 7 are two manholes leading from the surface of the ground into the sewer and through which entrance may be had thereinto, these being the usual manholes present n sewer systems in common use.

" Located adjacent the manhole 6 iswinding Y -mechanism of any suitable form, so far as my invention regardedin its broader aspects isconcerned, which mechanism, however, is shown as 1n the form of two wlndin drums 8, 9, both of which are'o perated rom an gine, so that either drum may be operated independently of the other. I

' The reference numeral ll'designates the bucket of my'improved sewer cleaning'device which is 'drawn back and forth through the section of the sewer to be cleaned, the same being provided with wheels 12 in order to reduce the friction, as willbe appreciated. The main body portion of the bucket maybe of various forms, the form illustrated in the ..drawings being cylindrical in cross section. The lower end ofthe body of the bucket is closed by two doors l3 pivotally connected to the lower end of the side wall thereof, and with which doors the ends of two fiexi ble members such as chains 14 are connected, as best shown in Fig. 2. These flexible members extend through guides 15 secured to the inner surface of thelwall of the bucket and are connected at their upper end with a ring 16 ;jwith whichring the end of a lifting rope isconnected to' thereby move the bucket to the left, Figifl, and then lift it through the manhole6 and dump its contents .into a tank,,wagon, or other receptacle, as indlcated in 2. I

llhe bucket 11 is filled by moving the same to theright, Fig. 1, while thelower the bucket is moved the end. of the door which slides along the bottom of the sewer will scoop up material to be removed and cause the entrance thereof into the body of the bucket.

The engine and winding "or hoisting mechanism is commonly supported upon'any -=suitable base such as is indicatedbythe ref erence numeral 17 and 18 designates a boom boom supports a pulleyorsheave block 20 having two wheels or sheaves to accommodate two. ropes 1n the embodiment of my invention illustrated; and the position ,of

said boom is controlled by a rope 21, one end of which is connected at:22 with .a-cross bar 23 of a vertically; arranged framework 24 carried by the base 17, and which rope passes about a pulley 25. carried by the" boom, and thence over the cross bar 23 and to thelefthand end of the framework, where it is secured to any suitable fastening device such as is indicated by the reference nume al 26. The purpose :of this-rope is to :permit the boomto swing-into the position showninfull lines inFig. 2 when the bucket Y vis to be dumped, and to return the same into the position shown in dotted lines in Fig. 2, and in Fig. 1, when the bucket is to be lowered into or drawn up through the manhole 6 l't will be appreciatedthat this swinging movement of, theboom maybe accom plished by any rope or equivalent, member whereby the boom may beoperated to at- ;tain the result above referred to;

, The reference numeral 27' designates a fixed abutment secured, in place at the end of thesection ofsewer to be cleaned which is l remote fromthe winding mechanism and other elements of the device, and which abutment serves as a fixed support for a ,pulley 28; and a second fixed abutment 29 is secured in place within the sewer at the end thereof adjacent the hoisting drums, and

The. reference numeral 32 designates a guide pulley rope whichextends fronrthe surface of the ground where its end is secured to. any support downward through the manhole 6 and about the pulley 31 and the free end ofwhich-rope is connected with a guide pulley 3.3; the purpose of said guide pulley being to change the direction of the rope,- whereby the bucket 11 is moved to the 7 left from the horizontal to the vertical, and

to permit the bucket to be lifted through the manhole, during which movement the guide pulley moves upward-along with the bucketythe end o f therrop'ewwhich is secured to a fixed support at the surface of the ground being unfastened at the beginning of the upward movement of the bucket and as the same is tipped from the horizontal position in which it is shown in Fig. 1 into a vertical position preparatory to hoisting it through the manhole 6, as will be appreciat'ed.

,The movement of the bucket to the right is produced by a rope 3a operated by the tothe remote endiof the section of sewer to be cleaned and about the pulley 28, and

thence to thebucket the end of said rope being connected either directly with the body of the bucket or with the lower of the .swingingdoors thereof, the latter being the method o f connection illustrated in the drawings, It will be understood from the above thatupon rotary motion being 1mpart ed to the said drum 8 the bucket will be moved to -the right, during which the.

solid matter will be scooped up. and carried into the body of the bucket, thus filling the same.

After the bucket llhas been filled by a movement to the right it is drawn to the .left by means ofa lifting rope 35 operated by the, winding :drum 9 'and which rope passesv upward and about the other of the sheaves of the pulley 20, thence downward through-the manhole 6 and through the guide pulley 83 thence along the section ;of sewer tobe cleaned to the bucket; where it .iseconnected with the ring 16 at the ends of the flexible members l-i, the other ends ofwhich flexible member areconnected with thedoors 13 as hereinbefore explained. The first movement of the said rope to the'left will obviously close the doors 13, thus retaining. whatever material may have been scooped up by the bucket, and the load which the bucket contains is obviously supported bythe said flexible members operating through the doors while the bucketis being V I ,moved along and lifted through the manhole wh ch last. mentloned abutment serves as a I support for two pulleys 30,311.,

6, and until the same is discharged from the bucket 1n the manner hereinafter explained.

I Vvheir the bucket reaches about the posi- *t1on indicated by dotted lines in Fig. 1, the free end of the guide pulley rope 32 atthe:

surface of the ground is released, whereupon and asthe bucket is lifted through the manhole 6 the'guidepulley passes along with the 'bucket, as indicated'in' Fig. 2. It will of course be understood that the guide pulley several -trips of the bucket through the section of sewer to be cleaned are ordinarily necessary in order to remove all the sediment or solid material therefrom. 1

The dumping of the contents of the bucket 11 after it has been moved into the position shown in Fig. 2, is accomplished by a dumping rope 36 having a hook 37 at its free end, and which rope extends through or about guiding means located adjacent the end of the boom, as through a 100p or eye 38' carried by the pulley block 20, and the other end of which is adapted to be secured to a fixed support indicated by the reference numeral 39, and which dumping rope serves to support the body of the bucket and permit the lifting rope to be slackened; whereupon the doors will open and the contents thereof escape through the bottom of the bucket.

In order to accomplishthis operation two chains 40 are provided, the lower ends of which are secured to the body of the bucket in any way, as by eyes carried by the guides 15 hereinbefore referred to. The upper ends of these chains are preferably connected with a ring 41 with which a hook 42 is connected through a short piece of chain, in order to provide for the convenient attachment or engagement of, the hook 37 of the dumping rope with the bucket in sucha manner that the same may be supported by the dumping rope after it "has been elevatedandswung intothe dumping position shown in: Fig. 2, whereupon and as the lifting rope 35 is slackened the doors 13 will, open and per mit the contents of the bucket to escape.

The hook 42 should be-hooked into the ring 16 when the bucket is to be lowered through the manhole 6, in which condition it re mains during the filling operation thereof,

and during the subsequent movement of the bucket to the left and while it is being lifted through said manhole, in order that the said hook may be in an easily accessible position when the hook 37 of the dumping rope is to be engaged therewith.

It will be appreciated, that the dumping rope is connected with the bucket when the same reaches about the position in which it is shown in dotted lines in'Fig. 2 upon its upward journey, and that said dumping rope is disconnected from the bucket before the'same passesback into the sewer. The said-rope is of course kept taut while the bucket is passing from the dotted line' position shown in Fig. 2 into the dumping posi: tion, and is then fastened to the securing member 39, or held inthe hand, while the bucket isdumped. Thereafterand until the bucket reaches the dotted line position in Fig. 2 upon' its return movement into the sewer the said'rope is slackened,and per mi-tted to move through the guide 38, and the said rope is unhooked from the bucket when the same reaches thedotted' line position referred to. 1 a
