ywound helical spirals 2' forming screws, the

eXtreme ends (a) of which are pointed. At-

tached to the central part 1 are curved prongsy or spurs 3 extending radially to approxi-v lmately the same diameter of the spirals 2 and ing no claim as to this particular method of fastening inasmuch as my invention does not include the cable to which device must be attached for operation but am showing -this method of attaching'as a means of teaching construction and operation of ymy device. Any other'substantial ymeans of connection of this device tothe cablev would be satisfactory, such as welding, clamping, etc.

' F ig. 2 isa horizontal view of the device.

.i to which are assigned the same numbers and letters designating the various parts as given to Fig. l, with the addition of 4 'which is the threaded cable-end.

of the spirals 2'are sharpened at (a) for easy entrance into the mass ofcsewer obstruction and the parts `vformingthese spirals should preferably be tapered toward theirextreme pointedA ends for best-operation.' 'Ihe spiral portions 2 andthe curved yprongs 3 may be welded to the central portion l. l

' Fig. 3^shows a sectional view kof a sewer in which the device is being' attached to a mass of roots. yThis View also'yshows the use of the cable'inconnection with this device. In this viewthe device is designated by the letter (f), (g) designates the cable, (h) the sewer and (i, z', 71)"'show the masses of lfibrous 'roots' whichhave entered vthe seweratthe seams. In operation this Vdeviceisi secured =to the end of 'acable (g) which vis flexible enough 'to make the necessary bends in the sewer and yet rigid enough towithstand suflicient twisting forceto operate the device and yhaving madean opening into the sewer at a convenient point r 'the device is inserted into the lsewer'v andpushed along bythe cable until e itt're'achesthe obstruction after which' it is screwed into the mass of lobstructing,matter soV It willfbe observed that the forward ends I' 'having attached thereto a pluralityof conn ,tok en age alsewerobstruction.'y y

This 'twisting is continued until the obstruction is loosened or until the device hasksecured a substantial hold upon the obstruction, after which it is withdrawn from the sewer by means of the cable, bringing the obstruction withit. It will be observed that as the parts'2 enter the obstruction the twisting action-ofthe spirals tend to draw the obstruction into a compactmass while the prongs 3 servetosev'ervfrom the walls of the sewer any portion of matter which may adhere thereto such as the princi--V pal roots inV the case of root obstructions.

" It is obvious that amore secure hold can `be obtained upon a mass of roots withl this device thanpwith any device employing ysimple hooks, prongs or spearsinasmuch as the spirals in vmy device operate as an extract- 'Y in grmedium throughout their entire length -giving the maximum grasp upon the obstruc tion.
