WILLIAM E. GLOW, OF CHICAGO, ILLINOIS.

Patented Feb. 14:, 1911.

Application filed June 15, 1909, Serial No. 502,319. Renewed May 10, 1910. Serial No. 560,463.

To all whom it may concern:

Be it known that I, \d' lLUJAM I GLOW, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Pipe- Cleaning Machines, of which the following is a specification.

The present invention relates to a machine for cleaning and polishing, more or less, the interiors and exteriors of cast iron pipes and the object of the present invention is to pro vide a machine which is simple in construction and eflicicnt in the accomplishment of this result.

The invention consists in features hereinafter pointed out, and shown in the accompanying drawings which are made a part of this specification and in which:

Figure 1 is a side elevation of the improved machine. Fig. 2 is an end elevation thereof. Fig. 3 is a plan view thereof with certain of the parts shown in horizontal section. Fig. 4 is a vertical transverse section on the line 4- 1 Fig. 3.

The machine has a base comprising two supporting beams,r which are parallel with each other and located in the same horizontal. plane. These beams may be supported by any suitable standard or means, not shown in the drawings. They are of su'liicient length to receive and accommodate pipes of the various lengths that are to be cleaned. At or near each end of these beams is a standard each of which preferably comprises two upwardly projecting arms, rising from the beams A and connected at top by a cross head. At one end of the machine the upwardly extending arms B are parallel, and the connecting cross head is shown at B At the other end of the machine the standards are shown at G and converge upwardly, the cross head being shown at 0 In both instances, however, the arms are vertical or perpendicular with respectto the general plane of the beams A. Below the cross head B arehangers D which carry the bearings for two pulleys E and F mounted upon a shaft G, one of which pulleys is nonrotatively secured to the shaft and the other of which is loosely mounted thereon. The non-rotative pulley derives its motion from any suitable motor mechanism. As shown in the drawings it derives its motion from a belt H or equivalent gear passing over a pulley I supported by the cross heads B ation.

but the details in this power-transmitting mechanism are left to the discretion of the builder. As before suggested the shaft G is supported and carried by the hangers I), but any suitablemeans carried by the standard may be used for supporting the shaft. The standard at the other end of the machine also has a hanger, lettered J, which carries and supports a shaft K, the two standards resembling each other excepting in the divergence and parallelism ofthcir upwardly extending supporting arms. The shaft K carries an idle pulley L and the shaft Gr carries a driven pulley L, both of which pulleys are circumferentially grooved as shown more clearly in Fig. 2, and around these pulleys passes a chain or other endless belt-like cleaning device M, the term chain as herein used being intended to comprehend any device of a belt-like character. so long as it is adapted to perform the functions hereinafter ascribed to the chain. This chain has an open link N and the adjacent link has a hook N in order that the chain may be parted for the purpose of passing it or at least one lap of it through the pipe to be cleaned, which is shown at 0.

Located above and parallel with the beams A are a pair of shafts P, journaled in suitable bearings supported by the beams. Each of these shafts carries a plurality of rolls, disks or wheels Q which are preferably circular or concentric with the shafts by which they are carried, respectively, excepting for peripheral notches or teeth, upon which the pipe to be cleaned rests, in the cleaning oper- One of these shafts is positively driven by any suitable mechanism. As shown in the drawing it is driven by. a beveled gear R, which latter derives its motion from the shaft G. The pipe to be cleaned, resting in the bite of the rolls, disks or wheels will be revolved and by reason of this revolvin of the pipe and the con tinuous passing of the chain through and upon the outside of it a thorough abrasion of the interior and exterior of the pipe will be accomplished, resulting in a thorough and efficient removal of roughness and irregularities of its interior and exterior surfaces. In Figs. 1 and 4c of the drawing the supporting and revolving rolls, disks or wheels, Q, are shown with peripheral notches or teeth, the object of which is to jiggle or jolt the pipe laterally, thereby accentuating or accelerating the action of the chain on the interior and exterior surfaces of the pipe. While this is the preferred form of these rolls, disks or wheels, still, in its broadest aspect, the invention is not limited thereto and in Figs. 2 and 3 I have shown rolls in the form of true circles and without any teeth. VVithont any means for restraining it the passing of the chain through the pipe would have a tendency to move it endwise in the direction of the travel of the lap of the chain passing through it and. in order to prevent this a retainer It is provided which straddles the pipe and engages its hub, with which pipes of this character are usually provided.

As above intimated this machine is for the purpose of polishing and cleaning both the interior and exterior of pipes. The cleaning and polishing of the interior of the pipe is accomplished by one lap of the chain, which passes through the pipe, while the cleaning and polishing of the exterior of the pipe is accomplished by the other lap of the chain, which sags from one to the other of the grooved pulleys and has contact with the outside of the pip'e, which, as before stated is constantly rotated, by the means described.

As shown in the drawing, the pipe is disposed or arranged in horizontal position, but this is not necessary, and if desired it may be arranged in an inclined position. In fact, the inclination of the pipe, as compared with the horizontal position, is preferable because when the pipe is inclined the dislodged particles will pass through it by gravity and thereby be discharged at its lower end. I desire to have it understood, however, that, in its broadest aspect, the invention is not limited to any specific location or arrangement of the parts of the machine whereby the specific position of the pipe relatively to a horizontal position confined.

Having thus described my invention, the following is what I claim as new and desire to secure by Letters Patent.
