TUBE-CLEANING MACHINE.-

To all whom, it may Concern: 16e it known that I, KARL MATHEUS, a citizen of the United States, residing at`Chicago, in the county of Cook and State of Illinois, have invented certain new and use- 'ful Improvements in Tube-Cleaning Machines, of which the following is a specification.

removing and disengaging scale and other matter which accumulates. upon the exterior of tubes, pipes, etc.

In designing the machine of the present invention, it is sought to provide means which will-operate simply and 4effectively to remove all matter from the outside of a tube, such means being readily adjustable to operate upon tubes of different sizes. It isfurther. sought, to rovide means for feeding or advancing t e work automatically during the cleaning operation.

Other objects of my invention consists in the means employed for controlling the pressure broughtto bear upon the work by the friction rollers, in the means for. adjusting the speed at which the scraping or cleaning o eration is 'performed according to the ciiaracte of the work, and to the machine as a whole and the individual parts thereof.

The invention further consists in the features of construction and combination of parts hereinafter described and claimed.

In the drawings, Figure 1 is a front elevation of the machine as a whole; Fig. 2V is an elevation of one side of the machine Fig. 3 is a front elevation in detail of the friction yrollers and supports therefor; Fig. 4 is a cross section taken on line 4 4 of Fig. 3, looking in the direction. of the arrows; Fig. 5 is a plan view of the base support upon which. the friction rollers are mounted; and

-Fig. 6 is a dia upon the frictlon rollers.

This invention relates in many respects to the general type of machine embodied in Lettersl Patent of the United States No. 968,610, issued .to me July 5, 1910. The main purpose for which such machine was designed, however, was for cutting and reaming sections of pipe, whereas the present invention is concerned more particularly with means for removing particles of matter, suele as scale, from the outer surface of such wor r.

ammatic view, looking down Specification of Letters Patent.

This invention relates to a machine for v which thereof, upon which the driving mechanism 'i is supported. .Upon either side of the front wall of the column formation near the u per end thereof,`there are provided gui e Patented Dec. 30, 1913.

ways 12, between which is mounted a vertically movable slide plate 13. A rack 14 formed upon the rear side of said slide plate is adaptedV to'be engaged by a pinion 15 mounted tupon a transversely extending rock shaft 16, the ends of which are journaled in the side of the main column formation of the machine. The rock shaft is operated by means of a counter- -weighted hand lever 17 which is keyed or otherwise secured to one end of the shaft, and-projects obliquely forward and upward in a position to be easily engaged by the hand f the operator.

The slide plate 13 is formed upon its outer face with a vertically extending T-sh'aped slot l18 within which rests a headed bolt 19,

and carries an adjustable journal'plate 20 tprovided with an opening through which the threaded end of the bolt 19 extends for the purpose of receiving a nut 21 thereon. The upper end ofthe adjustable journal plate is provided with an inturned lug 2,2 journals a Vhub 23 of'a hand wheel 24 threaded onto a fixed screw 25 which upwardly rprojects from the top of the slide plate. he arrangementis one whichpermits the journal plate to be vertically ad? justed by the rotation of the hand wheel to regulate its position with respect to the slide plate upon which it is carried. Thejjournal plate seryes as a mounting for a transversely extending journal sleeve 26, through which extends a section of the driving shaft 27, having on its forward end a driving roller 28 secured thereon as by meansof a nut 29.

The driving shaft 27 is 'rotatedl through the agency of a universal or flexibly mounted section of shaft 30 which, in turn, is connected with a power shaft 31 provided with suitable fast and loose pulleys 32 and 33, the same being mounted within journal boxes 34 formed upon the bracket 11. This arrangement is'such as to permit of the raising or lowering of the slide plate and the consequent change in angularity of the exiipsa bly nio-@atei shaft section il@ with respect to the shaft sections connected therewith, without loss of rotative effort.

rlhe driving roller 2S cooperates with inner and

outer friction rollers

35 and 36, respectively,vwhich rollersvare journaled bei tween a pair of inner bracket arms 37 and a pair of outer bracket arms 38, the lower ends of which arms are pivoted to lugs 89 formedupon a base plate 40. A bracket member 41 is secured to the front face of the column formation 10 adapted' to support thereon the said base plate and to center the same with respect thereto by means of an upwardly projecting boss 42 adapted to seat within an opening 43 formed in the under face of the base plate. By suitable means, as the' bolts 44 Ithreaded into the bracket arm through arc-shaped slots 45, the base plate with the friction rollers mounted thereon may be fixedly secured to the bracket member4 and adjusted with respect thereto,

as may be found desirable.

Between each pair of bracket arms is swiveled a screw block 4G, through which is entered a right and left screw 47 provided with a hand wheel 48; through a member 49 upwardly projecting from the lugs 39 and located intermediate the front and rear bracket arms the said screw is entered, which member serves as a journal mounting to prevent longitudinal movement of the right and left hand screw.

The pipe o`r tube to be Worked is placed uponthe

vfriction rollers

35 and 36, which, by means of the hand Wheel 48, may be adjusted to bring its upper surface into close proximity or actual contact with the driving roller, the normal vertical elevation of which can be likewiseadjusted by means of the hand wheel 24. Thereafter, when the parts are adjusted to the best position to act upon a pipe or tube of a given diameter, the

'cleaning or disengaging operation will be performed by depressing the vhand lever.

which operates the slide plate to bring the driving roller with the necessary pressure into engagement with the tube to perform the work thereon. `When the hand lever is thereafter released, it will be returned to its normal position and the driving roller thrown out' of contact with the .pipe or tube by the. action of the connterweight. The rack and pinion arrangement employed enables an operator to bring the driving roller into engagement with the tube or pipe with a veryv heavy pressure.

In order that the work which is being acted iipon by the'friction rollers may be automatically fed lengthwise therethrough, the axes of said rollers which are parallel to each other and which determine the position of the work held therebetween, are adjusted by turning the base plate upon the bracket member to-a position, such as is indicated in Fig. 6, where they are not parallel to the axis of the driving roller. `When so arranged, the Work which is acted upon will receive from the driving roller a rotary impulse as well as an impulse to move longitudinally due to the oblique position assumed by the Work with respect to said roller. The friction rollers become effective in disengaging matter, scale, etc., from the tube, because of the fact that the work is revolved as well as moved lengthwise against the grinding action of their revolving ser- -ratedsurfaces It is possible to use a driving roller having a serrated or toothed'surface to assist in the operation of cleaning olf the exterior of the .Work upon which it acts, but the machine, as shown and described, will be found entirely eiiective4 in performing the work.
