DEVICE FOR HANDLING FLUE-CLEANERS.

Specification of Letters Patent.

Patented Nov. 29, 1914).

Application filed March 16, 1908. Serial No. 421,343.

To all whom it may concern:

Be it known that I, MnLvinLn O. Lnwis, a citizen of the United States, residing at Ieoria, in the county of Peoria and State of Illinois have invented certain new and useful Improvements in Devices for Handling Flue-Cleaners; and I do hereby declare that the following is a full, clear and exact description of the invention, which will enable others skilled in the art to which it appertains to makeand use the same.

This invention has reference to an apparatus for use in handling flue cleaning devices.

An object of the invention is to provide means to carry and by which to insert a flue cleaning device into the flue of a boiler without the necessity of entering the latter, said cleaner being manipulated from out side of the boiler, the mechanism including means by which the device may be inserted into any desired flue.

Another object is to provide a mechanism by which the operator is enabled to quickly and positively locate the flue cleaning device above the mouth of and insert it into a given flue even though the flues are not visible to said operator. I

A further object is to provide a series of markings or callibrations for mechanism of this kind by which the operator can quickly and positively locate the cleaner at the mouth of any flue of a series though the latter may not be visible.

In order to clean the flues of large sized vertical tube boilers men are usually employed to enter the drums with which the tubes communicate to do that work. These drums are often diflicult to operate in and are usually too hot to remain in for any length of time thus requiring several men who relieve one another from time to time. In view of this I have devised an apparatus needing but a single attendant to perfectly and quickly clean the flues from a position outside said drum, said apparatus being shown in its preferred embodiment in the appended drawing in which Figure 1 is a vertical longitudinal section of the drum of a boiler showing my apparatus therein. Fig. 2 is a transverse section of a support showing an adjustable collar for the same. Fig. 3 is a transverse section of the support drawn to a smaller scale *ith a standard shown in connection therewith. Fig. l is a horizontal section of the support and a guide shown in Fig. 1. Fig. 4 is a modification of the parts shown in Fig. 1 for guiding a flue cleaning device into a flue. Fig. 5 is a plan of one of the sections of the support. Fig. 6 is a vertical section of the support and a detachable member for carrying a hose. Fig. 7 shows in perspective, part of the member shown in Fig. 6. Fig. 8 is a side elevation of a portion of the apparatus shown in Fig. 1 much enlarged. Fig. 9 is a front elevation of the same. Fig. 10 shows, in perspective, a portion of what is shown in Fig. 9. Fig. 11 shows, in perspective, certain callihrated portions of the apparatus, and Fig. 12 is a side elevation of the same with parts in longitudinal section.

A indicates the steam drum of a boiler of the vertical flue type, whose flues are indicated at B, while C is the usual man-hole in said drum.

D is an arm having at its end within the drum a slidable jaw E shaped to fit the drum head beneath said man-hole.

F is an outer companion jaw rigidly secured to or forming part of the arm D and having a face adapted to fit the outer surface of the drum head. A thread-bar G is secured at one end within the jaw E in any suitable manner and the other end extends through a depending portion H of the said arm D and receives an internally threaded hand-wheel J which bears upon the said portion H and serves through the jaw to clamp the arm D firmly to the drum-head. Said arm D has a Vertical extension or head provided with a bore as indicated at L in Fig. 12, to receive a sleeve M which is held fixedly within said head by means of a hand screw N, said sleeve extending rearward from said head to carry a driving-head O bored to receive it as shown in Figs. 8 and 12, there being a hand screw P extending through the said head O to engage said sleeve. In Fig. 11 two set screws 0 are provided to permanently engage the sleeve to hold it rigid relative to said head but said sleeve need not be separate from the head 0 but may be a tubular extension thereof to enter the head K as in Fig. 12. It receives a horizontally disposed support composed preferably of a series of pipe sections Q, indicated in several figures, one of which sections is illustrated separately in Fig. 5 there being suitable means at,the ends of said sections by which they may be readily attached to one another but this will be described presently. The carrying mech anism for the support Q, made up of the sections, may, of course, be mounted" in any suitable manner so long as it is fixed relative to the drum.

Vhen connected the sections constitute a rigid support of some length, Fig. 1, such support being rigidly held relative to the head 0 by the screw P therein, the inner end of the support being mounted in a standard indicated at R. Theinner end of the innermost section Q is bent downward substantially at right angles to its horizontal port-ion and adjustably secured thereto is a short length of tubing T of the same internal diameter as the inside diameter-of the lines to be cleaned which, serves as a. guide by which to direct the flue cleaner into a flue, said tube being adapted forvertical adjustment and held for instance by clamping rings S carried by the support Q as clearly shown in Fig. 4.,

The standard R hereinbefore mentioned preferably consists of a. member U bored toreceive a vertically adjustable pipe V held in any adjustment by means ofset screws IV. Secured to the member U are two legs widely separated at their lower ends to straddle several rows of flues and forming a broad base.

As shown in Figs. 1 and 3 the feet of the legs 2 rest upon the drum and are arranged to engage the ends of the flues so as to be guided thereby. In this way the supporting member Q, is arranged to be guided by the ends of the flues thereby throwing the strain of]? the carrier clamped at the manhole. The feet are preferably of such a length as to span or extend across at least two tube ends longitudinally of: the drum. In this way the guiding action will be facilitated since the feet will engage one pair of tubes before breaking contact with the pre ceding pair.

The pipe V has a split head composed of the members 3 secured together by means of bolts t, and the head carries the support Q which is permitted to rock freely therein. Carried by said support at each side of. the head is a collar 5 provided with a set screw- 6 so that said collars can be adjusted along the support to permit the latter to be shifted through the head to any desired position but any other means to provide for this adjustment, may of course be used.

The flue cleaning device may be of any approved formv such, for instance, as the rotary or turbine cleaner. I have not illustrated this devicehowever since no claim is made thereto per 86. I do show, however, a flexible hose 19 for carrying and driving said device though the equivalent of the hose may be used such. for instance, as a flexible shaft or othermeans that while imparting movement to the cleaning device will readily lend itself to the movement of which the hose or the flexible shaft is capable, that is to say, such as will permit it to be readily guided. into a flue though extending axially of the drum.

The manner of connecting the sections Q is as follows :In Fig. I show a coupling comprising a flange 7 of substantially the same diameter as the diameter of the sections and having at one side a stem 8 to slip into the bore of the section and permanently held therein by a rivet 9 or other suitable means. An extension or stem 10 at the opposite side of the flange is threaded toreceive the end of the next section which is threaded internally. This is clearly shown: in Fig, 5 wherein the threads of the sectionareshown by the numeral 11. hen two sections are connected a pin or wedge 12 is inserted through holes 13 in the pipe and through a corresponding hole 14 in the extension of the coupling which prevent the sections turning relatively.

The head 0- hereinbefore described, has two pairs of vertical extensions 15 all of which are slotted at 16 to receive slides 17 the corresponding pairs of which carry upper and lower rollers 18 between which is carried the hose 19 just mentioned which conveys the fluid for driving the turbine cleaner. The spindles which carry the rollers 18 are provided each with a gear 20, Figs. 1 and 9, the upper and lower ones being. in mesh. Between the two lower gears is a pinion 21, Fig. 1, driven by means of'acrank 22. The slots 16 in the members 15 open through the top of the latter so that pairs of the slides 17 may be removed together with the roller, Fig. 10. By this means rollers of other diameters may be substituted to suit the diameter of the hose in use. The slidesare grooved on their edges as at 23 and the inner adjacent faces of the members 15 are provided with beveled portions 24L to correspond with said grooves. Pivoted at one end on eachv of the members 15 is a cross-head 25 carrying a tension screw 26; the opposite end of said cross-head being suitably secured to the member 15, as, for instance, by means of a pin 27. A spring 28 shown in Fig. 9 has its ends resting upon opposite slides 17, the tension screw bearing thereupon and producing more or less pressure on the top rollers and consequently upon the hose. Movement imparted to the crank will turn the wheels 20 causing the lower rollers to revolve in one direction while the upper rollers will naturally revolve in the opposite direction due to the reverse movement imparted by the gears, the movement of all of the rollers being such, however, as to impart a positive movement to the hose in a given direction. The rollers are lagged with leather so that the wire wrapping preferably used will sink into it and in addition to this, as shown in Fig. 9, the rollers are also furnished with projections as, for instance, rivet heads, or the like, which act in the same capacity as the cogs of a wheel by entering between the convolutions of wire serving therefor to aid in the positive movement of the hose.

At intervals along the support made up of the sections Q, I provide supporting rollers 32 as shown, there being one at the bend of the support where it turns down to carry the guiding pipe T. Fig. 6 shows the manner in which the rollers are carried. A frame is provided which consists of vertical extensions 29 and a bottom whose under surface is grooved to fit upon the support and extending downward from said botton is a pin 30 extending through a hole 31 in said support. The roller 32 is mounted between the extensions 29 of the frame and pivoted to one of them is a member 33 carrying a pin 34;, the latter having a piece of piping 3S slipped upon it to constitute a roller. The opposite end of the pin 34: carries a member. 33 similar to 33 which rests upon the opposite frame extension 29. A spring 36 is secured at one end to the top of the member 33 its free end being bent and adapted to pass beneath a lug 37 on the frame. The hose pipe is placed in position on the roller 32 by raising the roller 38. The rollers 32 are readily removed from the support Q, when desired by lifting them to withdraw their pins 30 from the holes 31.

Under some of the old methods of cleaning boiler flues which open into a steam drum, it is often necessary after drawing the fires to permit the boiler to remain untouched several days before it had become sutficiently cool to permit men to enter and begin their work, or, if a device is used to clean the flues from a position outside the drum it is necessary for the operator to actually see the fiues so that he may be enabled to properly position the cleaner so that the work can proceed.

One of the purposes of my invention is to provide for cleaning the flues immediately after drawing the tires even though the drum is very hot and even though the operator is unable to see the fines for any reason. As a matter of fact if the fines can be cleaned before they have cooled and before they have become thoroughly dry the scale can be more readily removed. l/Vhile the drum may be still full of steam I can begin work. I employ certain devices by which the operator can readily place the cleaner opposite the mouth of any flue in exact position for work.

The forward or inner end of the sleeve M terminates at the front face of the head K and on its end face is a series of radial lines a, b, 0, (Z, 6, corresponding in number to the number of longitudinal rows of lines and which, in the figure named are for convenience indicated by the letters f, g, h, 2', Secured upon the head K is an indicator K which serves to indicate the central position of the middle mark of the series as Well as a means by which the operator can determine the proper position of the cleaner for a given longitudinal row of fiues it is desired to clean.

Extending along the support, composed of the members Q, is a line Q, Figs. 5 and 11, which line is designed to register exactly with the center line C of the sleeve. these lines are thus in register and directly beneath the indicator K the guiding pipe T for the flue cleaner is in register with the center line of fines h, Fig. 11. lVhen the operator desires, for instance, to clean the line of fines indicated by 2' the hand screw M in the head K is loosened to permit the sleeve to rock Within said head. By using the head 0 as a lever this rocking of the sleeve is accomplished. WVhen the mark 6 has been brought into register with the indicator the guiding pipe T will then be found to be in proper register with said line of fines z' and upon tightening the said screw N the entire device will be held in that position having been rocked, of course, within the standard at R which, together with the supporting member D holds the axis of the support- Q substantially in register with the axis of the drum so that the said pipe T will be substantially the same distance above the mouths of all the flues in any position it may be placed. Since the screw P of the head 0 secures the support Q therein that member must, of course, rock with the sleeve and it is evident that the remaining rows of pipes can be reached by the guiding pipe T by the method described, the lines a, cl and 6 corresponding to the fiues f, g and j respectively. The broken lines in Fig. 11 indicate the position of the head 0 when swung to bring the radial line b of the sleeve opposite the indicator K to position the pipe T above the flue 6 described, and the dotted line along the support Q, indicates the position of the center line Q, when swung to the position just described.

In order to bring the guiding pipe T into proper register with the transverse rows of flues I have provided on the support Q, a series of circumferential marks indicated in Fig. 1. Beginning near the forward end of the support these marks are indicated by the letters in, Z, m, 11., etc. Said marks are spaced apart a distance corresponding exactly to the distance from center to center of the fines. The line at a in Fig. l, is exactly in register with the face of the sleeve M which bears the radial lines a, Z), c, d, e, the marks at s in Fig. 12 making this clear. \Vhen thus in register the guiding pipe T is exactly in line with the most remote transverse lines of flues indicated by a.

When- By loosening the screw P in the head 0 the support can be drawn rearward or to ward the operator through the sleeve M until the line is in register with the face of the sleeve. This movement carries the guiding pipe T into register with the transverse line of fines indicated by Y. The remain ing marks will permit the operator to station the guiding pipe above any desired row of fines, it being my purpose to provide for each mark an indicating character to corre spond with a given line of lines and a given flue in that line whereby the operator is enabled at once to locate the flue he desires to clean. It is clear that even though the drum may be filled with steam at the time the apparatus is located for use, the operator without being able to see the fines can locate the guide T for the cleaner above any line of transverse fines by means of the circu1n ferential marks 70, Z, m, etc., and then by means of the radial lines a, b, a, (Z, a he can locate all of the fines of that row, and after cleaning them he can proceed to the next row and so on.

The indicating device and marks on the head and on the support Q constitute locating means so that the operator can properly locate the flue cleaner over a tube in the drum without entering the same. The line Q on the sections in connection with the pins 12 constitute locating means to locate the sections in proper relative position so that the line sections Q on the different sections will always be placed in the same relation and position with respect to the guide T.

hen placing the apparatus in the drum the standard It and the first length of the support are inserted through the man-hole, then the clamping arm D is set in place and secured after the centers of the bores of the sleeve M and the head 3 of the standard are made to coincide with the axis of the drum. Then one of the sections Q can be entered through the sleeve and connected with the first section. The first one or two rows of fines, or at least those within the limit of the sections are cleaned, then another section is inserted and so on until all of the fines have been cleaned. The lines Q of each section are made to exactly and permanently register with one another since after each said section has been screwed home the pins 12, before described, make such registering positive.

I have mounted the means that moves the hose so that it can swing with the support as already described and its weight when tilted toward one side is substantially counterbalanced by the weight of the downturned end of the support, the guide T and the flue cleaner, so that but little effort is necessary to obtain any desired adjustment The guiding member T of the support Q may be an GXLQDSlOD of the latter and not a separate part. That this may be under stood, Fig. i shows said member which is indicated by T; being shown as an integral part of the support Q. The member T or T is suspended above and clear of the mouth of the fine and is adjustable upon the support in the first form described to move it relative to the fines and secured by the bands S, and in the second form the same result is obtained by the adjustment of the part V in the standard R. By this means the said member or guide can be adjusted within the fraction of an inch from the flue ends and it can then be moved across the transverse rows by the support Q, without difiiculty and can be readily shifted over the longitudinal rows since it moves in a plane parallel to the plane in which the mouths of said rows lie. The adjustable collars 5 are provided on the support Q adjacentto the head composed of the parts 3 on the pipe V whereby the support may be shifted relative to the standard when desired though ordinarily as the support is moved the standard moves with it.

In using the member T the hose'may be withdrawn from the fines without shutting off the water and the turbine is therefore allowed to revolve within the member while moving the latter to a new position. The support Q is preferably made up of short lengths after the manner described so that in camped positions as, for instance, when the boiler is too close to a wall to allow the support to be entered in a full length the said sections may be added one by one as the work proceeds.

Various changes in the structure may be made without departing from the spirit and intent of the appended claims.
