PIPE-CLEANING ILC'HINE.

Specification of Lettera Patent.

Patented Aug. 19, `1919.

Application illed mh $0, 1919. Serial I0. 993,787.

To all 'whom it may concern:

Be it known that I, JOHN Gnon, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvcments in Pipe-Cleaning Machines, of which the following is a specification.

This invention relates to a machine adapted to act upon pi tubes, flues, etc., to clean o' and polis their exterior surfaces.

In the construction of mechanism for this purpose, it has been my aim above all to provide means for removing, disengaging, or inding olf the formation of rust, dirt, sca e, etc., in an effective manner without injnriously affecting the body of the pipe under treatment, and without mutilating or breaking down such threads as may be formed upon the pipe; and in accomplishing these endsto employ a. device that is essentially' simple and inexpensive both in construction and operation. It has, furthermore, been an object of this invention to utilize a mechanism that, because of its simlicity, is of relatively light weight and ence easily portable, so that: it ma be operated in places Where greater a vantage and eonvemence is to be gained by bringing the machine to the material that is to under treatment, rather than vice-versa.

Vith these and other objects in view, I

will now refer to the accompanying drawi in which is exhibited a preferred embliment of the rincipal parte of this invention, Fi re being an end elevation, Fig. 2 a si e elevation, and Fig. 3 an enlarged fragmentary detail in cross section taken on line 3 3 of Fig. 1.

As shown in the drawing, use is made of a frame which may conveniently be setup on any suitable support, the frame comprising companion arms 5, each anged at itslower end as at 6 to receive a bolt 7 that secures the device in place. Guides 8 are provided on each arm as shown, and supported by the uy per ends of the arms is a cross head 9 t rough which extends a. screw shaft 10 operable, if desired, by a hand wheel 11. Arranged to slide vertically upon the guides is a box 12 constitutinlg a journal for a rotatable shaft 13 whic ma be driven by power applied in any suita le manner,

box having a swivel connection with the screw shaft 10 by which its vertical position 56 within the frame may be adjusted Mounted adjacent 4the front side of the Awidth of the frame is a block 14 having thereon a transverse channel for the reception of a U- shaped journal box 15 which is removably secured in place. This journal box carries two freely rotatable companion rollers 16 which are in co rative relation with a third roller 17, which is locked to the driving shaft 13 by any approved means. The pipe to be treated, designated as 18, is arranged for longitudinal travel between these three rollers in the direction of the arrow, it being understood that some sort of a support is provided for the pipe ends during its movement through the machine.

I will now describe in detail the construction and arrangement of the three rollersthe upper one having driving and two lower ones driven relation-as this represents one of the important and novel improvements of this invention. First of all, it is to be noted that the axes of the several rollers are parallel, and that each roller is provided with certain circumferential ooves or channels, their interrelation ing best shown in Fig. 3. I prefer that the grooves in each roller shall be two in number, with their sides square cut, the grooves in the driving or upper roller bein denoted as A and B, while those on the riven or lower rollers are denoted as C and D, the uncut rtionsof each roller periphery constitutmg ribs or flanges whose acting surfaces are adapted to engage with the pipe. As a further surface orination, the three ribs or flanges of the driving roller 17 may be provided With shallow cross cuts 19, preferably in a slightI an lar relation, as Shown. The rollers 1n their relation to each other are secured in the machine with the driven rollers 16 in a coincident plane slightly ahead of the driving roller 17, by which arrangement the driven rollers are the first to engage the pipe; and in the preferred construction the forward end of the driving roller lies apfpligoxiinately midwa of the nt groove C in t e driven rollers, while the rear end of the driven rollers lies approximately midway of the width of the rear groove B of the driving roller.

In the operation of the machine, the pipe to be treated is placed u on the lower rollers and the haid wh p erated tohadjust eupper or riving ro er upon t e ie with the desired rassure. The poweli" Iis then' applied to drive thenpper roller 17,

and this results in the pipe also being revolved; at the same time it causes the pipe to travel l hwise through the machine. The driven ro ers first act upon the pipe to my therefrom the rust or other foreign matter and generally, to clean up the surface, while the driving roller forms a and polishing action. e travel of the pi' is caused more perceptibly by the upper ro er, altho h the formation and interrelationship of the rollers is :e: ry to this action. The pro ulsion of the pi may be attributed'to use of proper y formed rollers, those below being slightly ahead, while the driving roller above is correspondingl behind, so as to exert what may be term a tilting tendency upon the pipe, the resultant efcct being that of traction such as to draw the pipe through the machine as it unde its treatment.

The machine whi has been described in detail is manifestly simple both in its construction and operation. It embodies but few parts and hence islight and adatpted to be moved about wherever its use is esired In its action upon the pipes undergoing treahnent, very satisfactory results may be obtained without ail'ect' any threads that may be formed on the ody of the pipe. Realizing, however, that the rinciples of this invention are susceptible o embodiment in forms other than the articular one shown and described herein, desire that all mich modifications or which are based either in whole or n the improved in part upo features peculiar -to this invention, should be included within the scope of this patent,

as more delinitely set forth in the claims following.

I claim: v

1. In a pipe cleaning machine, the combination of a driving and two driven rolleis man to receive between them a pipe for treatment, the three rollers having parallel axes and be' of substantially the same length with the ends of the driven rollers coincident, the drivinl roller, however, be-

-nation of a riving ro ing therewi the acting surfaces of each roller being grooved circumferentially substantialiy as described.

2. In a pipe cleaning machine, the combination of a driving and two driven rollers arranged to receive between them a pipe for treatment, the three rollers having parallel axes and being of substantially thesame length 4with the ends of the driven rollers coincident, the dri roller, however, beingvnalned thereilvliltl, substantially as descri 8. In api cleani machine, the combi- `er and a plurality of drivenl rollers a to receive between all of them a pipe for treatment, the several miauw rollers lparallel axes and being of substantially the saine length with the ends of the driven rollers coincident the driving roller bei misalined therewith, e ac surfaces o all the rollers being groov circumferential] substantially as described.
