CLEANING DEVICE FOR WASTE OR DRAIN PIPES Filed Feb. 12, 1952 Patented dan. 1Q, 1933 seran' r. nenn or muon, NEW vom:

l-v' DEVICE FOB WASTE OR DRAIN PIPEB I .appncsuon sied February-'1a 1932. serial No. 592,615.

My invention relates to cleaning devices or Waste and drain pipes, or the like.

An important object of the invention is to provide a device of the above-mentionedchar- 5 acter, which may be conveniently applied to the Waste or drain pipe for closing its intake end and introducing Water, under pressure, into the pipe to force the blockage upon the same. m A further object of the invention is to provide a device of the above-mentioned character having an eXpansible plug or closure element vvhich is automatically expanded by Water pressure, prior to the entrance of the Water into the pipe.

A urther ohj ect of the invention is to pro'- vide a novel and simple means for holding the device applied to the Waste or drain pipe.

A `further object or the invention is to provide a device or' the above-mentioned character, which is simple in construction, merrpensive to manufacture, and convenient 1n use.

tion will be apparent during the course of the following speciiication.

in the accompanying drawing, forming a part or? this specication, and in which like numerals are employed to designate correspending parts,

Figure 1 is a side elevation oi a device emhodying my invention,

Figure 2 is a central vertical longitudinal section through the same, and $5 Figure 3 is a horizontal section taken on line 3-3 of llligure 1. 1

ln the drawing, wherein for the purpose ot illustration is shown a preferred embodiment of my invention, the numeral designates tubular body portion, formed of metal, or the like, and having a cylindrical shell l1, suitably attached to its free end. lhis shell is provided upon its periphery i withv openings 12 for the 'free passage of the l Water. The 'forward end of the shell 11 carries a disc 13, rigidly attached thereto by screws, or the like, and this forward end and the disc 13 are provided With aligned openings 1/1. An outwardly opening valve 15 is 50 hinged to the disc 13, 16, and this valve @ther objects and advantages nii the inven has connection with a retractile coil spring 17, attached to the rear end of the shell 11, as shown. y Y y The numeral 18 designates a disc, having a central a erture 19 for the passage of 55 the tubular ody portion 10. A supporting element 20 is carriedvby the tubular body portion, and includes companion semi-cylindrical portions 21, carrying radially extending pairs of apertured ears 22, secured together by bolts 23, or the like. These bolts serve to clamp the semi-cylindrical portions 21 to the tubularbody ortion 10. Arranged between the aperturedD ears 22 are locking levers 24, fulcrumed upon the bolts or pivots G5 23. The disc 18 has a larger diameter than the drain or Waste pipe 25, while the locking levers 24 have their free ends in the form of outwardly bent jaws 26, operating through slots 27, and these jaws are adapted to engage within the pipe 25. In order that the loc ing levers 24 ma be held in the closed position, a U-shaped7 link 28 is pivotally mounted vupon the free end of one lever 24 and is adapted to engage -With teeth 29, formed upon the other lever, as shown. Other suitable means may be employed to hold the locking levers 24 in the closed posio tion, if desired.

The numeral 30 designates an expansible plug or sack, which is annular, and has its inner edges mounted upon the forward and rear ends of the shell 11. The upper edge of this sack is clamped to the to of the shell by the disc 18, While its lower-e ge is clamped to the top of the shell by disc 13, thereby eecting Water-tight joints.

rllhe operation of the device is asfollows:

The plug or sack 30 is inserted into the intake end of the pipe 25, in the distended condition, and the valve 15 is then closed. rlhe jaws 16 engage the inner Wall of the pipe 25 and have clamping engagement therewith by drawing locking levers 24 inwardly, theseI levers being then locked in the closed position. The device is, therefore, securely at#` tached to the pipe 25. Water under suitable pressure, is then supplied through the pipe 10 from a hose 10', or the like, which may be connected with a spigot. When the Water enters the tubular body vortion l0, it passes freely into the eXpansi le plug 30, which is first expanded until it forms a Water-tight contact with the inner Wall of the pipe E25. When this expansion is effected, the pressure will open valve l5 sufficiently to permit of the escape of the water. The spring 17 is of such a tension that it will automatically close the valve before the expansible plug will contract, and this plug is, therefore, maintained expanded during the passage of the Water under pressure, past the valve l5. This water under pressure will, therefore,

ass through the pipe 25, and remove thererom the blockage. By releasing the locking levers 24, they may be swun outwardly and the device readily removed rom the pipe 25.

It is to be understood that the form of my invention herewith shown and described, is to be taken as the preferred example of the same, and that various changes in the shape, size and arrangement of parts may be' resorted to Without de arting from the spirit of thev invention or t e scope of the subjoined claims.

Having thus described my invention, what I claim 1s:

l. A device for cleaning waste or drain pipes, comprising a tubular body portion for the passa e of water under pressure, an eX- pansible ollow plug connected with the tubular body portion and in communication therewith and adapted to be expanded by the water pressure, means to permit of the discharge of the water from the tubular body portion into the Waste or drain pipe, and ocking means carried by the tubular body rtion for engagement with the waste or rain pi 2. A evice for cleaning waste or drain pipes, comprisin a tubular body portion for i the passage of a uid under pressure, a hollow expansible plug carried by the tubular body portion for insertion within the pipe and to engage with the inner Wall of the same upon being expanded by the Huid under pressure from the tubular body portion, and an automatically seating outwardly opening valve y for controlling the discharge oft .e fluid from the tubular body portion to the pipe.

3. A device for cleaning waste or drain pipes, comprisinff a tubular body portion, a

ollow expansib e lug connected with the outlet end of the tubular body portion, there being an outlet opening in communication with the expansible plug, an outwardly open ing valve to cover said opening, and yielding means tending to seat the valve.

4. 'In a device for cleaning waste or drain pipes, comprising a tubular body portion, a shell secured to the outlet end of the tubular body portion, an expansible hollow annuler at its forward end, an outwardly opening valve to cover the outlet opening, and yielding means to oppose the outward opening movement of the valve.

In testimony whereof, I affix my signature.
