of the drawings, the sleeve 7 comprises any desired number of tubular sections and also as disclosed by these figures the rod 12 is made up of sections which are removably and pivotally connected. One end of each of the rod sections is bifurcated, as at 23, to resleeve 26 is of any desired length, and the" said sleeve has its outer surface gradually 1 tapered to the ends thereof; Passed'o'ver' the stem an'd the flared periphery of the sleeve there are any desired number of cuffs-27 whosebores are flared. The cuffs at points opposite the center thereofareperipherally formed with seriesof oppositely disposedsubsta-ntially V-shaped notches 28. The inner and straight'walls of these notches are designed tobe engaged by a; suitable implement, suc'has a punch andthe saidpunch is subjected to a force such as the impact :of a hammer orthe like and-whereby the sleeves are brought into tight frictional engagement with the fiar'ed-splitsleeve 26 to cause the said sleeve to frictionally engagewith' the stem sections or'tocause the cuffs to travel off of-the sleeve to permit ofthe said sleevebeing removed from the stem sections. By thissimplearrangement it'will be noted that thefhandle portionof the device may be lengthened or shortened to suit conditions.

Thedevice is operated by at least three hands when the culvert is of; any determinedlength and is never operated by less thantwo hands, one of which-grasps the tool-adj acen't to' the blade 1, the second,-when three are employed, grasps the tool close tothe'center thereof while' the other hand grasps the handle of the tool, The blade is, of course, inserted in the culvert and the pointed end thereof is: shoved against thedirtor other material that clogs the culvert. The oper ator at thehandle endofthe device -manipulates the lever1'9- to cant, or if desired, to oseil. late the blade so that the same will both penetrate and agitate the dirt or other clogging. material. By thus manipulating the tool the same will dig through" the clogged material and by canting the blade and removing'the same from: the culvert the clogged material will be drawn therefrom and dumped to one side of the culvert, The operation is, of course,- continued until the culvert is entirely cleaned. V

The construction and advantages of the improvement will, it is thought, be apparent to thoseskilled inthe art to which such'invention relates so that further detailed description-will not be" requi-redi Obviously I do not wish to: be restricted to the precise details herein set" forth and the'reforehold myself entitled to make such changes therefrom as fairly fall within the scope of what I claim.

Having described the invention, I claim:

1. A cleaning device for culverts, comprising a blade having a straight head, a tubular stenn-a handle on the outerend thereof, comprising a bifurcated member, armsextending from the stem and pivotally secured to the 7 blade, and to the head adjacent to the ends -thereoff,-' arod member pivotally secured to the ing a blade havingja-straighthead, a tubularste-m, a handle onsthe-outer end. thereof-comprising abifurcated member, arms extending from the stem-and pivotally secured to'the blade'an'd" to the head adjacent to the ends thereof, a rodmernber pivotally secured to the head adj aee-nt-the top thereof and guided through the stem, a leverhavin'g a rounded end which: is;v pivotally secured in: the bifurcated'head and to which lever= the rod ispivoted'a-ndia combined spacer element for the arms of the bifurcated vhead 1 and a stop element for the lever when swung thereagainst.
