AUTOMATIC FEEDER FOR CLEANERS 0R SCRAPERS FOR BOILER TUBES OR FLUES.
SPECIFICATION formingl part of LettersPatent N o. 645,894, dated March 20, 1900, Application had Muy 29,1899. serial No'. 718,688. (No met) .To @ZZ whom it may concern: u
Be it known that I, OYRUS S. DEAN, a subject of the Queen of Great Britain, residing at Fort Erie, county of Welland, Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Aug tomatic Feeders .for `Cleaners or Scrapers for Boiler Tubes or Flues, of which the following is a specification. My invention relates to automatic feeders for propelling cleaners or scrapers'through boiler tubes or flues.
The 'object' ofv they present invention is the.
provision of an improved feeder for use in 'connection with scrapers o r cleanersV having propelling devices ofL novel r construction adapted for operation by steam or air pressure in such manner that'they will beA held in strongactive contact with ,the Itube or ue by the steam orair pressure while they are being operated thereby, thus insuring the automatic feeding of the device through the tube orrflue while the scrapers'or cleaners are operating thereon and obviating the necessity of feed-I ing by hand, as usually done heretofore. l
Having the foregoing object in view, the invention comprehends improved propelling devices adapted for` operation by' av suitable steam or air motor and mounted and arranged in such manner that the air or steam pressure acts on them and holds them in contact with the tube or flue as long as it is supplied to the y driving-motor.
The invention consists, further, in certain improved features and novelfcombinations of parts,fully described hereinafter and particularly recited in the appended claims.
In the accompanying drawings, Figure 1 is a longitudinal section of the invention shown in a tube or flue, certain parts being in dotted lines and in full lines; Fig. 2, a cross-section with the propelling or feeding devices in full lines, taken on line 2 2 of Fig. 1; Fig.v 3, a view similar to Fig. 2, taken on line 3 3; and Fig. 4, a sectional end view.
The invention is shown in a section of'boiler tube or iiue 1. The body or casing of the device is composed of two cylindrical sections 2 and 3, fitted together by a lap-joint at and air chambers 5, which match of the tub'eorliue.
each other. Extending through the section 3 are two steam or air ports l6, arranged in diametrical relation and opening into the chambers 5, and the section 3 is also provided with similar ports 7, extending therethrough.
' At the outer end of section 2is a cylindrical casing 8 for any suitable self-contained steam or air motor employed to operate the propelling or feeding devices, as well as the cleanersor Scrapers, (not shown,) while at the outer end ofsection v3 is a head orca 9 havin a pipe-coupling to which the steam or air pipe can be connected. Bolts 10, running through n the sections 2 and 3V and the casing 8 and head 9, hold them firmly together.
' Each section of the body lcarriestwo propellers or feedersvarran ged parallel, with their axes coinciding with chords or lines of less length than thediameter of the body or casing and adapted to operate on the opposite sides One pair of propellers or feeders are, however, arranged atright angles to the otherpair, and consequently active contact is had with four flue at the same time.. The propellers or feeders have a cylindrical body 11, snugly fitting but easily'slidable in parts ofthe tube or a chamber 12, which opens through the exterior of the body at one end and is blind'at its inner end, where it is continued in a small pressure-chamber 13, which is in communication with the port 6 or 7. The cylinder 11' has a` reduced stem, provided with a piston 14, adapted for movement inthe pressure-chamber, a pin 15 being provided to prevent the feeder from dropping out when the device is being carried about from place to place. The inner end of the cylindrical body of the feeder is provided with a Worm-wheel 16, and the outer end, which is adapted to operate on the tubeor iiue, is rounded and ridged or toothed, as shown at 17.
The numeral 18 designates a driving-shaft adapted for operation by the motor or engine employed, which is journaled in the casing 8 and the sections of the body and hasits inner end suitably stepped in the section 3. This shaft has two similar worms 19 and 20, the former of which meshes with the worm-Wheels of the feeders in section 2 and the latter with IOO those contained in section o. The cleaners or Scrapers (not shown) are carried on the outer end of shaft 18, so as to be in advance of the propelling mechanism.
The operation is as follows: The steam or air entering the head 9 passes through the ports and chambers and finally reaches the engine or motor, which puts the drivin g-shaft in rotation, thereby revolving all the propellers or feeders. The steam or air while passing through the ports acts on the pistons of all of the feeders with sufficient pressure to force them outwardly and hold them in strong contact with the interior of the tube or fine while they are rotating. As the roughened ends of the feeders touch the tube at only one point of their periphery, their rotation brings different portions of their peripheries successively in contact with the tube or fine surface, resulting in the automatic propulsion of the device through the tube or flue. When the steam or air supply is cut off, the feeders slide easily inward, so that there is no interference when placing the device in position or sliding it from place to place in the tube or flue.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
I. In an automatic feeder for cleaners for tubes or fines, the combination with a body or casing adapted for movement through the tube or flue, of a feeder or propeller carried by the casing and movable relatively thereof toward and away from the interior surface of the fine, means for projecting said feeder out from the body by Huid-pressurel and maintaining it in contact with the fine-surface thereby and means for rotating the propeller.
