SPECIFICATION forming part of Letters Patent No. 232,406, dated September 21, 1880.

Application filed May l2, 1880.

5 Improvement in Flue-Cleaners, of which the following is afspecication.

The invention relates to expansiveuecleaners for clearing ilues of furnaces from any accumulation of deposits oi' smoke or other forio eign substances. i

The object ot' my invention is to provide an expanding scraper' which will be yieldingin its nature and be capable of being expanded or contracted in its diameter, so as to accurately tit and ll the bore ofthe tubes, and which may4 be readily expanded and contracted while in the bore by simply turning its handle in the proper direction, and also to provide an elastic or yielding cleaner which may be readily adzo justed to compensate for wear, and which will remove the loosened deposits from the lues.

To this end the invention consistsin a, conical-shaped scraper having several blades arranged in conical form and so combined with a 2 5 traveling follower as to be capable of being expanded or contracted in its diameter while in the iiue.

rIhe invention further consists in a eXible or yielding cleaner constructed of elastic ma- 3o terial, combined with a gritty substance in such manner that the said cleaner will be capable ot' having its body enlarged or expanded ,in its circumferential direction.

Theinvention further consists in the combination, with the elastic cleaner, of washers t having conicalshaped leading or guiding ends,

as more fully hereinafter specified 5 and the invention nally consists in the particular combination and construction of parts, as more In the accompanying drawings, in which similar letters of reference indicate like parts, Figure l represents a perspective view ot a line scraper and cleaner embodying my inven- Fig. 2 represents a sectional elevation ofv the same, and Fig. 3 a sectional view with the parts arranged differently for accomplishing the same results.

The letterAindicates the stem of the device,

5o which is provided with a screw-thread, s. A

indicates the attaching-collar, made solid with (Model.)

said screw-threaded stem, and provided with bore s', for attachment to a rod, R, by which the device is operated.

The letter B indicates a clamping-washer made with tapering flanges extending from said washer to the end ot' a sleeve cast solid with both the washer andiian ges. This washer I denominate a leaderi 'Ihe letter B indicates a similar leader. These leaders are provided with a bore of a diameter sufcient to freely receive the screw-threaded stem A.

C is an elastic cleaner, composed of rubber or other suitable materiahwith which iis incorporated emery or other equivalent gritty sub stance. rFhis elastic cleaner is also provided with a bore of sufficient diameter to receive the screw-threaded stem A, and is clamped between the leaders B and B on the stem.

The letter D indicates an expansion-.scraper composed of several slightly-curved blades, c, constructed from flat tempered steel and of a tapering form, as shown in Fig. l. rIhe said blades are secured to a block, b, by the conical band c and a screw or other suitable fastening device. As thus constructed the scraperD is conical in form and is capable of being readily expanded.

The letter E indicates an expanding screw collar or follower, which tits the screw-threaded stem A, and is adapted to work on the same and in the interior of the conical scraper from 4its open end, as shown in Figs. 2 and 3.

The letter F indicates a set-nut fitting the screw-threaded stem A, for clamping the leaders B together for upsetting or expanding the elastic cleaner G.

I prefer to arrange` the several parts or de vices on the screw-threaded stem A in the manner shown in Figs. l and 2 for ordinary work, as when thus arranged the scraper D, when the device is thrust forward through the flue, will cut or scrape the deposit on the surface of the bore, while the elastic cleaner will follow and carry the loosened deposits forward after the scraper. 1n some cases I would arrange the several devices substantially as shown in Fig. 3, in which I would expand the scraper to a larger diameter than that of the cleaner, and would commence operations in the liuc at the most distant end and workthe device in the'flne short distances each time, and

IOO

gradually increase the distance at each thrust until the near end of the flue has been reached, when I would expand the elastic cleaner to the size of the bore, or slightlylarger, and run the devices backward and forward alternately through the whole of' the ue.

If desired, the several devices may be arranged on thc screw-threaded stein substantially in the order shown in Figs. l and 2 of the drawings, with this dierence: that the expanding scraper will be arranged with its larger and scraping end toward the attachingcollar A', and the elastic cleaner will be toward the rear end of the stem, in which case I would use the device to clean the Hues by drawing it toward the operator.

I n operatin gmyimproved device the scraper D should be expanded bythe expanding screwcollar E to a diameter which will about correspond with the diameter ofthe flue to be cleaned. The elastic cleaner is also to be expanded in its diameter by forcing the leaders toward each other.

Ihe scraper will, when the device is operated, loosen the deposity on the interior of the flue, while the elastic cleaner will carry the loosened deposit out of the same. The emery or other gritty substance incorporated with the cleaner will scour the interior of the liuc, effectually removing any particles left by the scraper.

Having thus described my invention, what I claim isl. The elastic cleaner C, composed of rubber or other similar material and a gritty material, in combination with mechanism for expandin g said cleaner, substantially as specified 2. The combination, with the screw-threaded stem A, elastic cleaner C, leaders B B', and nut F, of the expansion-scraper D and screw collar or follower E, substantially as set forth.

3. Ina flue-cleaner, the combination, with an expansionscraper, ot' an elastic gritty cleaner capable of expansion, substantially as and for the purposes set forth.
