9 Claims.

This invention relates to a pipe cleaning machine and. is an improvement over copending application, No. 710,362. It is an'object of the invention to provide a machine of this character which will more satisfactorily, more quickly, and

efliciently, remove dirt, rust, scale or other foreign accumulation from theexterior surface of a p n prmhg A ,1. ,J

Another object of the invention is to provide a pipe cleaning machine which can be operated with safety and which can be set and a pipe passed through and cleaned without the attention of an attendant. eh Ariotlir'object 'of the invention is to provide a 5 machine of simple and inexpensive construction,

which can be easily transported, which is constructed to be adjusted to accommodate pipe of various sizes and having selective single and dual rollers designed to perform a double function of both guiding and cleaning the pipe in its passage through the machine.

A further object of the invention is to provide cleaning elements having cutting blades which can be easily detached and replaced in the field.

Other objects and advantages will be apparent from the following description taken in connection with the accompanying drawings, wherein Fig; 1 is a side elevation illustrating one application of the invention;

Fig. 2, a front elevation;

Fig. 3, a perspective taken from the rear, and

Fig. 4, a perspective from the front.

Referring to the drawings a frame H! is formed of uprights and cross members of angle iron or other construction. On the frame ID a pair of cutting elements H are mounted on parallel ShaftYTYTEiiHTYIffifig el nei'it s havlfig parallel removable cutting blades |3 fastened in place by a pair of bolts M at each end of each blade. Each of the cutting elements is provided with a sprocket l5 driven by a chain I6 from a sprocket ll mounted on a drive shaft driven from a source of power (not shown) by means of the pulley 9. When the pulley I9 is driven the cutting elements I l are both rotated in the same direction so that a'pipe or other substantially cylindrical body 20 resting upon the upper surface of the cutting element in contact with the same will be rotated.

In order to maintain the work, that is, pipe 20 in contact with the cutting elements and exert sufficient pressure against the pipe to cause it to be properly cleaned, an adjustable lever or presser bar 2| is provided. The lever 2| is formed of spaced side bars and carries a pair of guiding and cleaning rollers 22 on one side and a single, slightly smaller guiding and cleaning roller 23 on its o her side or disposed opposite the guide rollers 22. The guide rollers 22 are supported by a bracket 24 and the guide roller 23 is supported by a bracket 25, the

brackets

24 and 25 being attached to the spaced side bars which form the presser bar 2|. The

rollers

22 and 23 are mountedto rotate on spindles 26 and 2land are grooved to cause the pipe being cleaned to be fed through the machine more quickly.

When a large pipe is being cleaned it will be rotated by the cutting elements I and the rollers 22 will bear against the pipe and guide the same.

TIiseTollersJkwillalsmpgm the pipe against [A the rotating cutting elementmeh'oilersdl will not onlyguide the pipe and press the same againstthe cooperating cutting elements but will perform a cleaning action. If a small pipe is being cleaned the roller 23 will engage the pipe and perform a similar dual function such as that just described.

In order to cause the pipe to travel through the machine, the guiding rollers which are normally disposed parallel to the cutting, rollers II are shifted slightly. Tomake such angular adjustment possible the p esser bar or lever 2| has one end pivotally mounted in a manner to permit the rollers 22 to be raised and lowered and at the same time adjusted angularly to permit the axis to be changed out of a position parallel with the axis of the cutting elements II, the latter serving to cause the traveling of the work through the machine in either direction depending upon the angle of adjustment.

The pair of spaced plates which form the presser bar or lever 2| are connected at one end by a cross member 28 which is adjustable on an upright post 29, a set screw 30 being provided for securing the cross member in proper position. The post 29 is provided with a fiattened side having a plurality of set screw receiving depressions 3|. The shaft 29 is supported in bearing brackets 32 mounted in spaced relation on the frame H). A set screw attached collar 33 permits vertical adjustment ofthe shaft 29, said collar maintaining the shaft in a definite position. A similar collar 34 limits the upward movement of the shaft and in order topermit a limited resilient upward movement a spring 35 is confined between the collar 34 and the underside of the bracket 32 on the frame of the machine.

The post or shaft 29 is located at the rear of the machine and at the front of the machine the presser bar or lever 2| is connected to a similar upright post or shaft 36 carried by an adjustable bracket 31 slldable axially of the cuttingelements carried by the machine to give the lever 2| a swinging movement about the post 29 as a pivot. .The post or shaft 38 is provided with ,a pair of set screw collars 38 which can be set at the desired position for the proper vertical adjustment of the post 36. When the upper collar engages the bracket 31 it limits downward movement of the shaft 36 while the lower collar 38 limits the upward movement of said shaft. A spring 39 performs a function similar to the function of the spring in permitting a certain amount of resilient movement upward of the shaft 36 to permit a bump or coupling to pass the cutters.

The upper end of the shaft 36 is connected to the presser bar or lever 2| by an adjustable connection including a manually operable lever which whenthrown in one position maintains the front end of the presser bar in its lowermost position with the rollers in contact with the work and when thrown in another position maintains the front end of the presser bar in its uppermost position, with the rollers out of contact with the work.

As shown particularly in Fig. 4 the side bars of the lever are connected by a lost motion connection at their front ends by a cross member 40 slidable on the shaft 36, such lost motion connection being formed by bolts or studs in the The cutters 22 being set at the proper angle by shifting of the bracket 31 by means of the handle will cause the pipe to travel through the machine. When the handle 45 is swung to the left the pipe will travel to the right and when the handle 45 is swung to the right the pipe will reverse itself and travel backwardly or to the left.

When it is desired to clean a pipe of an external diameter considerably less than 2 inches the presser bar or lever 2| is reversed to bring the guiding and cleaning rollers 23 into contact with the pipe where it will operate to guide the pipe through the machine and clean the same as well as cause travel of the pipe through the machine.

To produce this reversal or inversion of the bar cross member extending through slotsin,thepost23 until the'levez u is-brought back into side bars. The ends of-thec'ross member are connected by means of pivotally connected links 4| and 42 with a second or upper cross member 43 fixed on the upper end of the shaft 36 by one or more set screws 53, two of which are shown in Fig. 1, but only one in the other figures. A handle 44 is carried by the links 42 which handle and links 42 form in effect a bell crank lever for shifting the links from the position shown in Figs. 3 and 4 to the position approached by the showing of Fig. 1, so'that when the handle is swung 180 and overlies the lever 2| the links 42 are inverted and consequently the distance between the

cross members

40 and 43 is shorter.

In order to change the angle of the rollers 22 relative to the cooperating cutting elements the bracket 31 carrying the shaft 36 is slidable along the frame of the machine. This bracket has its upper arm extending over the inner edge of the machine frame on which it is mounted and has its lower edge provided with a similarly extending element whereby the bracket is'prevented from becoming disengaged from the frame but is free to slide laterally thereon.

In order to provide for the necessary sliding movement of this bracket 31 a lever 45 (see Fig.

4) is pivoted at 46 on the machine frame and is connected by means of a link 41 with the braQrgt 31. Swinging of the lever 45 on its pivot will move the bracket 31 and produce the desired angle of adjustment of the rollers 22. In order to fasten the bracket 31 in fixed position a clamping screw 48 is provided and a crank 49 is carried by the screw for manipulating the same. A brush 50 is provided for cleaning the pipe after it has been subjected to the rotating cutters. This brush 50 is driven (see Fig. 3) in any desired manner as for example from one of the chains I6 which drive the rotary cutters. The chain engages a sprocket fixed to stub shaft 5|, connected to drive the brush by means of the belt 52.

In operation, when a pipe of 2 inches or larger in diameter is to be cleaned this pipe is .placed between the rollers as shown in Fig. 4, the handle 44 being thrown over beyond the position in which it is shown in Figure 1 substantially 180 to permit the pipe to be inserted, then the handle is brought forward into its lowermost position as shown in Figs. 3 and 4 to bring the rollers 22 into contact with the pipe. Rotation of the supporting cutters II will produce rotation of the pipe being cleaned and this rotation will impart rotation to the rollers 22 which'will guide and clean the pipe,

operative position. If the entire front assembly be disconnected from the post 36 in the reversing operation and connected again to the post 36, the extremity of the handle 44 will extend oppositely from that shown in Fig. 2. The presser bar or W lever 2| may be disconnected from the cross member 40 and reversed in the manner just described and when reconnected will not invert the handle 44.

The brush 5|! will remove any loose dirt or particles on the pipe and if a shoulder or union is encountered the handle 45 may be operated to .cause a brief reversing of the movement of the pipe to clean behind such shoulder.

It will be readily understood how when the machine is set and a pipe is passing therethrough, attention by an attendant is unnecessary. Further, when an attendant is present the front upright shaft or post 36 will prevent the pipe from being discharged or forcibly ejected forwardly which might cause injury to the attendant and any inequalities on the surface of the pipe are accommodated or compensated for by means of

springs

35 and 39 which give the presser bar or lever a resiliency at each end.

Should an inequality on the pipe or other means break or injure the cutting blades I3 the injured .blade gorijlages camasilyje removed and rew placed in the field by removing the two bolts of screws in each end of the blade.

By cutters as referred to in the claims, is meant rotary cleaning elements of the character to produce rotation of the pipe to be cleaned by engagement therewith, the expression being intended to cover brushes of sufficient stiffness to produce the necessary rotation.

It will be obvious to those skilled in the art that various changes may be made in my device without departing from the spirit of my invention and therefore I do not limit myself to what is shown in the drawings and described in the specification but only as indicated in the appended claims.
