WILBER D. FORSYTH AND ENOS T. BELL, OF .PITTSBURGH PENNSYLVANIA,

srncrrrcnrion forming part of Letters Patent No. 698,193, dated April 22, 1902.` Application led January 17, 1899. Serial No. 702,472. (No model.)
' T0 all whom/ t may concern:
Be it known that we, WILBER D. FonsYrH and ENOS T. BELL, citizens of the United States, and .residents yof Pittsburg, in the 5 county of Allegheny and State OfPennsylvania, have invented certain new and useful Improvements in Boiler-Tube Cleaners; and
we do declare thefollowing to be a full, clear,
and exact description of the invention, such :o as willenable others skilled in the art to which it appertains to make and use the same, reference being had; to the accompanying drawings, and to letters f reference marked thereon, which form a part of this specification.
r Figure l of the drawings isa representation of a perspective view, partly broken away',
showing the invention as in application. Fig.
' zo end elevation of same. Fig. 4 is a detail view illustrating the stud C3 of the bracket. i
This invention has vrelation todevices for operating boiler-tube cleaners and is designed to provide means whereby the feed-rod of a z 5 boiler-tubecleaner may beY driven by a direct motor connectionitherewith while capable of being readily moved fromonetube of a'boiler tofanother.
With this object in View the invention con- 3o sists inthe novel construction and combination of parts, allfas hereinafter described,`and pointed outin the appended claims.
Referring to thel accompanying drawings, the letter A designates thefeed-rod of a boilertube cleaner, (indicated at B,) said'rod in operation being rotated at a highl rate of speed, while at the same time it is moved longitudinally to carry the cleaner through the tube being cleaned.
C designates a bracket or casting which is mounted to slide laterally upon a fianged guide rail or bar D, being actuated by a feedscrew D. Said screw has a bearingat each end portion in lugs d of the bar or rail D and engages a nut C of the casting C. It is provided at each endwith an operating-handle D2. The slide portion C2, which engages the bar or rail D, is made in two sections, which are bolted or clamped together and seat between themaJ depending cylindrical stud or 5o stem C3 of the bracket proper atthe forward portion of the bracket. By loosening the fbolts which clamp this stud or stem the motor and feed-rod may be readily turned there- -on to enable the feed-rod to yenter a tube of Vthe boiler which may have become warped at pose of moving the bar in these guides windlasses F and rope connections F are shown.
We do not, however, confine ourselves to any iparticular means for supporting and moving the Said bar 0r rail, as various devices may be employed for that purpose. The arrangement shown and described has, however,
proved very satisfactory and convenient for 7o' Vthe purpose.
G designates a motor or engine, the base portion G of whose casing is securely bolted or otherwise secured to the bracket or casting C. This motor or engine may be of any suitable rotary type, operated by steam, water, electricity, or other suitable power. A steam-motor is, however, preferred, as it may be readily coupled up to the steam-generators of the plant in which'the apparatus is being 8o used. The shaft Gr2 of the motor is journaled at one end in bearings H, mounted in avertical arm of the bracket or casting,l and has ixed thereto a spur gear-wheel I. The bracket vorcasting also has a horizontal forWardly-eX- tending arm C4, provided with a transverselywhich it is keyed atj', and is prevented from such removal by the clamp J2.
L designates a casing which surrounds the gear-wheels I and K, being secured to the boxing enlargement above referred to at the top and bottom thereof.
In operation the bracket or casting C is adjusted on thebar or rail D to bring the feedrod into alinement with the particular tube ot' the boiler which is to be cleaned, the said bar or rail D being also adjusted vertically to bring it into proper relation to the hori-V zontal series of tubes in which such tube is situated. The cleaner is introduced into the tube an d the motor is started, thereby through the gears I and K rotating the feed-rod. As the operation continues the said rod is pushed longitudinally into the tube, its spline @sliding in the keyway ot' the sleeve J. A small stream of water should be kept flowing into the tube during the operation to prevent heating and to remove the loosened and disintegrated scale. As soon as one tube is completely cleaned the bracket or casting C is moved laterally on thebar or rail D into proper position for the next tube in the same horizontal row or series, and when that row or series is cleaned the bar or rail is raised or lowered on its guides to bring the devices into proper position for the next row orseries.
Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-
l. In mechanism ofthe class described, the combination ot' the transverse bar or rail, means for vertically adjusting the same, the laterally-adjustable slide carried by said bar or rail, the bracket having the cylindrical downward extension and the upward extension, the clamp upon said slide engaging said downward extension, the outer rotary sleeve journaled in said bracket, the inner concentric endwiSe-removable sleeve rotatably connected to said first-named sleeve, means for securing said innersleeve from endwise movements,the feed-rod engaging said inner sleeve, the rotary engine carried by said bracket, the shaft of said engine, having a journal-bearing in said upward extension, and carrying a gear-wheel meshing with the gear-wheel upon said outer sleeve, substantially as speciiied.
2. In mechanism of the class described, the combination of the transverse bar or rail, means for vertically adjusting the same, the
laterally-adjustable slide carried by said bar or rail, the bracket upon said slide, having a transversely split cylindrical boxing, and the semicircular enlargement connecting the sections ol" said boxing, the rotary sleeve journaled at opposite ends thereofin said boxing, the gear-wheel mounted centrally ot said sleeve in the space separating the sections of said boxing and partly inclosed by said enlargement, thefeed-rod engaging said inner sleeve, the rotary engine carried by said bracket., the shaft of said engine carrying a gear-wheel meshing with said first-named gear-wheel, and the guard-strip secured at one end thereof to the upper portion of said enlargement, carriedV around the gear-wheel upon the engine-shaft, thence partly around the gear-wheel upon said sleeve, and secured to the lower portion of said enlargement, substantially as specified.
3. In mechanism of the class described, a transverse bar or rail, a laterally-adjustable slide mounted upon said bar or rail, a bracket upon said slide,and having a cylindrical downward extension at one end portion thereof, clamped to said slide and revoluble therein to allow said bracket to be turned, a rotary sleeve having bearings in the opposite end portion of said bracket, the intermediate portion of said bracket resting and turning upon the upper surface of said slide, a feed-rod actuated by said sleeve, and a rotary engine mounted upon said bracket, and geared to said sleeve, substantially as specified.
4. In mechanism of the class described, a transverse bar or rail, a laterally-adjustable slide carried by said bar or rail, a bracket upon said slide having a boxing at one end portion thereof, an outer rotary sleeve journaled in said boxing, an inner endwise-removable sleeve rotatably engaged by said first-named sleeve, a clamp upon said bracket and engaging the outer end of said inner sleeve, a feed-rod actuated by said inner sleeve, anda rotary engine carried by said bracket, and geared to said outersleeve, substantially as specified.
In testimony whereof we affix our signatures in presence of two witnesses.
