Application filed leoemser 19, 1903. Serial No. 468,27;

To alt whom it may concern:

Be it known thatwe, Pinon A. Gannnan and FRANK 0. Rnnronn, citizens of the United States, residingat Louisville, in the county of Jefierson and State of Kentucky,

provenients in Cleaners for Mains and Pipes, of which the following is a specification.

This invention is an appliance for cleaning out water and other mains or pipes which may have become foul or obstructed by incrustations, sediment, or othr r substances; and more particularly in appliance of this kind which is operated by the pressure within themainorpipe.

The object of the present Invention Is to provide a cleaner of the hind stated which will readily adapt itself to bends or angles in the main or pipe, and also one wl'iich will pass openings in the main or pipe without danger of sticking or getting caught, and which. will pass rigid obstructions without injury.

With the foregoing objects in View, as well as others which will be apparent when the invention is better understood, the same consists in the construction and arrangement of parts hereinafter described and claimed,

reference being had to the drawing heretoannexed, in which: u Figure 1 we longitudinal sect onal view of i the appliance in position within a main or p1pe. Fig. 2 is. a transverse section on the line 2-2 of Fig. 1 Fig. 3 is a transverse section on the line 3-3 of Fig. 1.

In the drawing, 5 denotes a series of longitudinal resilient strips which are secured at their ends to conoidal blocks 6 and 7', re-

spectively, whereby a structure is had which is tapered at its ends. To the outer surface of each strip is secured a pair of scraperblades 8 having'their scraping ed es curved to conform to the inner surface 0? the main or pipe to be cleaned. The blades are presented in opposite directions, and are set on the strips to extend obliquely with respect to the axis of the main or pipe.

for the blocks 6 An adjustable connection j and 7 is provided, said connectionco nprising a screw-threaded spindle 9 extending rear- -ifardly from the center of the inner end of.

the block 6, in the direction of the block 7, in which latter block is a central longitudinal bore, in, which is mounted a stem 10' having Specification oi Letters Patent.

a threaded bore into which the spindle screws. The stem projects from both ends of the block 7, the threaded bore being in that end of the stem which pro'ects from the inner end of the block, said on extending in the direction of the "block 6, and also being .provided with a collar 11 which abuts against the inner end of the block 7. The stem fits loosely in the bore of the block 7 so that the latter is free to slide back and forth thereon, and said stemis also rotatable in the bore of the block. The'other end of the stem is provided with a head-:12 having a Socket 13 for a purpose to be presently. described, The outer-end of the block 7 has a central'recess 14 through which the stem 10 passes, and

coiled around the stem, between the head 12 arid the inner end ofthe recess, is aspring 15 which normally holds I the block 7 pressed against the collar 11, said spring opposing",

away from the block 6;

By reason of the herein-described connection between the blocksyfi and 7, it will be seen that when the st m o is rotated, the blocks will ap roaeh -each other, or-recede, according to te direction infwhich the stem the movement of the block in a direction is rotated, and as the strips 5 are resilient;

they will be spread or'contracted, thus mov ing the scraper blades 8 outwardly'or inwardly, whereby they are adjusted to the diameter of the main or pipe to be cleaned, and by these meanswe are 'alsoable to re '4 late the degree" of. pressure" the scraper bla es exert on th'ei'nner surface of the main or'pip'e. By making the block 7 slidable on the sten'i 10, the scraper blades are permitted to yield when they encdunter a rigid obstruction, so that they may pass over the samewithout injuryfand when'the obstruction is passed, the spring 15 restores the parts to their nor mal position. I V j a From the front end or apex of the block 6 projects a-s'hortstem 16 which is threaded to screw into a "disk 17. In front of this disk, and spaced a suitabledistancetherefrom, is

a second-disk 18, the two disks being connected by aster 19. Each disk has a series of 0' en-ings 20, which are controlled by a rotata le damper 21. To the back of the disks are secured leather- 01" other flexible packing was-hers 22 to render the same wa-' ter-tight, said washers haying a greater diameter than the disks, so as t'o project beyond the peripheries thereof. The washers eiso enabling two or more of the appliances to he haveopenings which re ings of thedisks. the pressure of the Water or other fluid in the Ernan or pipe against the disks forces the epee therethrough, the disks operating as pistons of an engine. By the dampers e area of the openings may be aried according to the pressure in them'ain or pipe. With a high pressure the dampers are, set to uncover a large area of the openings, and

ister with the open with a low pressure the openings are partly or g on the disk 17,

entirely coveredj Two disks are employed to'prevent the a phance from getting caught 111 passing si e- ;openings in the main or'pipe. To further guard against this, we mount spring strips said strips extending in an outward curve in the direction ofthe, disk 18. The periphery of each disk is made up of hinged sections 24, in order that the disks nlay pass rigid obstructions. A' spring hinge 253 provided for said sections in order that they may be restored to their normal position after the obstruction is passed.

The socketed'head' 12 is for the purpose of It w'i 1 he understood that .to one of the pistons, and having coi pied together; 0 ihe' apphance herein described 18 simple in structure, has no complicated parts to get out of order, and it efl'ectualiy serves the purpose for which it is intended.

We do not limit ourselves to deteiis of operation or constructionv as shown, as these may he modifiedin many particulars with out dejmrting'from the spirit of our invention. w
