To all whom, it may concern Be it known that I, MARTIN J. TrionsEN, a citizen of the United States, and a resident of lVeehawken, in the county of AHudson and State of New Jersey,have invented a new and Improved Tube-Schaper, of which the following is a full, clear, and exact, description.
`My invention relates generally to b oiler tube scrapers and` morey particularly is di- 'reeted to an improved device of this'cla-Ss designed to more thoroughly and-etl'ectively 'clean such tubes in the manner designed to prevent the material scraped from the-tube from becoming wedged therein and clogging the same.'
The principal obj ect of my invention is to provide a new and improved boiler tube scraper ofsueh construction and embodying such parts that, in addition to the scraping action on the Vinterior of the tubes whereby the material thereonis removed therefrom, the said n'iaterial will be crushed or broken up into line'particles so that as the scraper is moved through the tube such material will not tend to form a'mass which will obstruct the tube. A
A further object of my invention is to provide a new. and improved tool for cleaning and scraping boiler tubes; the tool is provided with suitable elements t'or scraping the deposit t'i om the tube and with other ele-v ments for crushing the said removed deposits asv well as deposits not removed so that as the devicetravels through the vtube piling up of the removed material is avoided and clogging thereot'is prevented.
Other objects and advantages of the invention will appeal' as the description thereof proceeds, all-,ofywhich is particularly pointed out and included in the appended el aims.
Reference. is to be had to the iuzcompanyv ing drawings forming a part of this speci.- iieation in which similar characters ot'rct'erence denote eorrespoiuling parts in all the views, and in which* Figure lis a perspective view ot the tube cleaner in operative position; Fig. 2 is a ver-v tical sectional view thereof; Fig. 3 is a seetional view on the line 3-3 oi. Fig. 2; Fig. 4 is a modified form ol blade used in the scraper; Fig. .3 is a 'lop plan view ol a modilied structure; Fig. (3 is a longitudinal sectional view thereof on the linee- (3 ol' Fig. 5;
Fig.- 7 is a side view of-a modied form of blade. 1 y I The scraper embodies a suitable body member l having down-turned sides 2, be-
tween which a number of wheels 3 are positioned, the peripheryof each of the Wheels heingserrated or notched as at 4, the Wheels being supported on a shaft 5 secured in each of the down-turned sides. It' so desired', the wheel 3 maybe provided with a central opening 6 of greater diameter than that of the shaft 5, the wheels heingsuitably positioned thereon by ineans ot'- a sleeve 7 which incloses tieularly in Fig. l.
Secured on the top side o the' body member l and extending longitudinally thereof are the bladeslQ, preterably formed from a. single piece of materialhnd' secured to the body member in any desirable manner, preferably by means ot screws 13, the intermediate portion between the blades being provided with an opening 14 which engages the projection 15 on the body member whereby the parts-are held in proper relative-position. v
v'ltet'erring particularly to Figs. 1 and 2 it will be noted that the edges ot each of the blades l2 lie on curves substantially the same as the/'shape of the interior of the tube with which .the scraper is to be used, the blades being bent, the intermediate portion of the blades, however," being flat and rigidly seeured in position.
`In place of the blades 1:2 with the eon -tinuous edges thereon, it may be desirable in somo instances to provide the blade shown in Fig. 4 wherein the curved ends ofthe blades 12.', l2 are serratedor notched, as at 100, in orderto provide a structure which in some. instances `may be more effective in removing the de osits from the interior of the tubes. The s ape of the edges, -however, is not essential inasmuch as the shapes of such edges require variation in order to adapt the device to tubes of different sizes and inasmuch as .the number of wheels 3 will also be varied, depending on the diameter of the tubes, such changes being matters of detail and tend toward the more eiiicient performance f the functions desired.
It is to be noted that the distance from the edge of one of the blades to the outer ends of the teeth 4 on the wheels 3 is substantially equal to or suiliciently greater than the diameter of the tubes with which the device yfrom one end thereof and is held in close engagement With the tube, the blades being suliiciently flexible to permit movement thereof in adjusting .the edges to the interior; the scraper is moved through thel tube by means of the rod or handle 10, the edge ci the blade l2 which is in advance of the toothed Wheels 3 Will scrape the interior oit the tube, thereby causing the removed deposit to fall to the bottom of the tube, this deposit being broken or crushed by the action of the teeth 4 on the Wheel 3. rllhis crushing or breaking up of the deposit, in addition to placingthc deposit in better con-- dition for removal, also prevents packing of the deposit therein as the scraper is'moved through, inasmuch as the wheels in .their movement through the tube do not push the deposit bodily forward but engage therewith to break it up, the teeth passing through the deposit. While the toothed Wheels operate as described it is also to be noted that'during the initial passage of the scraper through' the tube these teeth engage the deposit adjacent thereto so that, whi e this deposit may not lbe as effectively removed as by the blades, it is broken up to a certain extent, being thereby placeduin better lcondition for complete removal by the blades.
Referring particularly to Figs. 5 and 6,
l the body member. l is provided with the before-mentioned handle 10i and also the notched or serrated Wheels 3,- thc blades 12a,
however, presenting a slightly diderent con! structione' The forward blade is similar to shown in Figs. l andi?, the rcar blade, however, being shaped as shown particularly in Fig. 5, the curvature thereof being such that the 'upper portion of the blade merely rests or bears against the inside ot the tube and it is not intended that such engagement is to effect the removal of any deposit therein but is simply' to provide a rear bearing portion so that the device may be held Within the tube. A The intermediate portion between the blades is slighllycurved, the purpose being that more or less adjustment of the blades is permitted by tightening thenuts 13', thc resiliency ot the metal holding the blades i'n firm engagement with :hoezeer the nuts 13 or with Washers 200 positioned thereunder. The projection l5 on the body mcinberengages in an openingT ifiin 'the intermediate portion. of the blades, such engagement properly positioning the parts,'the tubular shape of the blades permitting the adjustment before-mentioned as Well as the resilient engagement of the parts when the device is in usc.
ln Fig. 7 the rear blade 1Qd .is omitted and in its place a roller 'ZO is provided which is mounted on a suitable shaft il carried in oppositely positioned ears 72, secured to the interinediate portion having at its other end the blade 12a similar to'lwhat'has been already described. This modification provvides for easier movement of the device in cleaning a tube since the removal of the deposit is ettected by the blade 12a, the roller providing a rear bearing portion having a rolling friction only whereby the function of the notched Wheels 3 andf'the blade 12a is more easily performed. The intermediate portion of this modification may be hori zontal, as shown in Figs. l and 2, or may be concave, as shown in Figs. .3 and 6, the concave structure probably being more preferable inasmuch as the parts thereby adapt themselves to the size of the tube when the device is inserted therein. The of the different parts of the device will depend upon the size of the tube with which itis used as Well as the nature of the tubes and the character of the deposits formed therein, the relative thicknesses oll substances of which the parts are made being determined by the stresses to be borne by these parts, the purpose and object being toy provide an improved device which will op crate in an effective manner, the construction being such, however, that excessive cost of production is unnecessary.
