WILLIAM D. LOCKE, OF MASSILLON, OHIO.

SCALING DEVICE.

Specification of Letters Patent.

Patented Get. 7, 1919.

Application filed December 16, 1918. Serial No. 267,035.

To all whom it may concern Be it known that I, WILLIAM D. LOCKE, a citizen of the United States, residing at Massillon, in the county of Stark and State of Ohio, have invented a new and useful Scaling Device, of which the following is a specification.

This invention relates to metal working machinery and more especially to a device for removing the scale which occurs upon iron and steel bars during the process of their manufacture, the object being to construct a machine that will cause the scale upon the heated bars to rise in the form of blisters, loosen the said blisters and break them into fragments and then thoroughly remove them from the surface of the bars.

With this object in view the invention consists in the novel construction and arrangement of parts, hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form', proportions, size and minor details of construction may be made within the scope of the-appended claims, without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings: Y

Figure 1` is a plan View of my scale removing machine.

Fig. 2 is a side elevation thereof.

Fig. 3 is an end elevation.

Fig. 4 is a longitudinal, vertical section through the machine.

Similar numerals of reference indicate corresponding parts throughout the several figures of the drawings.

The frame of my lmchine comprises the upright standards 1 and 2, which standards are spaced apartand secured to the Hoor, a base or other suitable support. At one end of the frame is arranged a table 4, the said table being supported between the spaced standards, and a roll shown at 5 is arranged adjacent the inner extremlty of the table with the center of its periphery at the top and in alinement with the upper surface of the table.

The roll 5 is journaled in sliding bearing blocks 6, one of which bearing blocks is slidably mounted in a vertical aperture 7 in either of the standards 1 and 2. ln horizontal alinement with the roll 5 arc similar rolls 8 and 9 which are also journaled in sliding blocks shown at 10 and 1l, respectively. The bearing blocks are mounted in slnnlar guide-ways formed in the standards l and 2. In a horizontal plane somewhat less in distance above the plane in which the above described rolls are mounted than the diameter of one of the said rolls, are rolls 12 and 14, which rolls are arranged in staggered relation to the rolls 5, 8 and 9 as distinctly shown in Fig. 4. The rolls 12 and 14 are mounted in sliding bearing blocks set in guide-ways in the standards so that all of the above described rolls are adjustable vertically. Interposed between the rolls 5 and 8 is an idle' roll 15 which is also adjustably mounted and slightly less in diameter than the rolls 5 and 8 and a similar idler 16 is likewise mounted between the rolls 8 and 9. An idler 17, identical with the idlers 15 and 16 is mounted between the rolls 12 and 14. It will be seen from the above description and Fig. 4 of the drawing, that the arrangement of the rolls leaves a tortuous passage between the upper and lower sets of rolls so that a bar of metal such as indicated at A in Fig. 4 would be alternately bent, lirst downwardly and then upwardly in passing between the said set of rolls.

A water pipe shown at 18 extends longitudinally above the set of rolls at about the center line between the pair of standards. The pipe 18 will be provided with perforations shown at 19 in vertical alinement above eac-h of the .rolls and is attached to any suitable source of water supply so that Water admitted to the pipe will be allowed to drip or spray from the perforations on to the rolls therebeneath.

Arranged substantially in alinement above and below the course pursued by the bar in leaving the roll 9 is a pair of steam jets 19 and adjacent the pair of steam jets is a pair of adjustably mounted rolls 20 which are designed to act as feed rolls and for other purposes to be hereinafter set forth. A table 21, the top surface of which is in alinement withv the space between the rolls 20 and designed to support the bar of metal on leaving the rolls 20 and guide it between a pair of adjustably mounted rotating brushes 22 and 28, which brushes will be formed of steel wire bristles. A second guide table 24 is arranged at the outlet side of the brushes and a second pair of steam jets 25 are Aarranged similar to the jets 19 at the far extremitjv of the table 24. Adjacent the jets 25 is a second pair of rolls 26, which also act as feed rolls to dischar e the bar on to the table 27, at the outlet en of the machine.

Attached to one journal of the roll 5 on the outside of the standard 1 is a gear 28, which gear is arranged to mesh with a similar gear 29 carried by the journal of the roll 12. Similar gears 30, 31 and 32 carried by the rolls 8, 14 and 9, respectively, are arranged to mesh in the order named, so that motion imparted to the gear 28 will cause the rolls 5, 8 and 9 to be rotated in one direction and the rolls 12 and 14 in the opposite direction. An idle gear 34 driven from the train of gears just described is arranged to mesh withvone of the intermeshing gears 35, which gears are attached to the journals of the rol-ls 20 and a train of idle gears shown at 36 engages one of the gears 37 attached to the journals of the rolls 26. -From the above description with reference to Fig. 1 it will be seen that the rolls 5, 8, 9 and the lower rolls 2O and 26, are all driven in one direction while the rolls 12 and 14 and the upper rolls 20 and 26 are driven in the opposite direction, thereby producing a direction of rotation in all of the rolls to properly carry a bar of iron fed in the left hand end of the machine through the said rolls to the said brushes and deliver it upon the table 27 Mounted upon the outer extremity of the journal of the roll 5 adjacent the gear 28, is a relatively larger gear 38, which meshes with a relatively small gear 39l mounted.

upon the shaft 40 of an electric motor or the like shown at 41, A bracket 42 extends outwardly from the standard 1 and has an up-turned portion to form a standard 43 in which standard is mounted an idler gear 44 arranged to mesh with the gear 39. A sprocket 45 is mounted on the shaft 40 adjacent the gear 39 and over this sprocket passes a sprocket chain 46, which extends upwardly and passes over a sprocket 47 attached to one journal of the brush 22. Attached to the shaft on which the idler gear 44 is mounted is a sprocket 48 over which passes a sprocket chain 49 to a sprocket 5() mounted on the journal of the brush 23; It

is thus seen by this arrangement of gearing that the brush 22 will be rotated in the same direction of rotation of the upper rolls 20 and 26 while the brush 23 is rotated in the same direction to the direction of rotation of the lower rolls 20v and 26. To the journals at one end of each of the rolls 9, 12 and 14 is attached an adjusting screw 51 which adjusting screws extend upwardly through the standard 1 and carry on their upper ends hand wheels 52. Beveled pinions 54 attached to the adjusting screws are arranged to mesh with beveled pinions 55 secured to horizontally extending shafts 56 which extend to the opposite side of the machine and on their opposite ends carry beveled pinions 57, which pinions are arranged to mesh with beveled pinions 58 attached to adjusting screws 59, which adjusting screws are arranged to operate the journals of the rolls 12 and 14 mounted in the standard. 2. A similar arrangement of adj justing screws, beveled pinions and hand wheels is provided for the upper rolls 20 and 26 and the upper brush 22. It will thus be seen that by operating the hand wheels both ends of the roll or brush desired are properly and simultaneously adjusted.

The operation of my machine will be as follows: The bar or sheet of heated metal emerging from the furnace at a temperature slightly above cherry red will be passed to the table 4 and engaged by the roll 5 whence it will be directed between the rolls 5, 12, 8, 14 and 9 as shown in Fig. 4. Because of the peculiar arrangement of the said rolls the heatedVV bar will sustain an alternate bending upwardly and downwardly. As previously stated a ine spray of cold water is permitted to fall from the perforations 19 in the supply pipe on to the upper face of the rolls and as the said rolls rotate the wet faces will be brought into contact with the red hot bar. This contacting of the cold wet face of the roll with the hot surface of the metal will cause the scale to rise in the form of blisters on the face of the -bar and the alternate bending which the bar receives passing between the rolls will crack the said blisters. Further progress of the bar brings it be` tween the steam jets 19', which jets are directing Nsteam at considerable pressure across the faces of the bar and all of the scale blisters which have been broken will be considerably loosened by the steam so that as they pass between the pair of rolls 20, the said rolls will partially pulverize them and complete the loosening process. Advancing farther the bar lis brought into contact With the rapidly rotating brushes 22 and 23, which brushes as described, are rotating in the same direction of the respective rolls 20. The bristles in contact with with the direction of the movement of the bar but at a much greater speed and as the said bar passes between the said brushes the steel bristles practically clear the surface of all scale. Passing the brushes another air of steam jets is encountered by the ar, which finally and thoroughly removes all particles of loosened scale, which may have escaped the brushes. The feed rolls 26 will now` deliver a erfeetly clean and finished bar on to the ta )le 27.

With the use of my machine the 'bars are delivered directly from the furnace to the machine and the piekling process is thus obviated. Those skilled in the art `will the pickling process for the removing of the scale will eect an enormous economy. It is also well known that in the ordinary ybars on emerging from the fur-f, nace are atvonce passed between the'rolls and where -.particles of scale are upon the surface of the bar as it passes between thev rolls, the said rolls will drive the said particles of. scale" into the surface of the hot bar andwhen the b`ar^has been pickled y and cleaned it will be seenthat the surface `isv pittedv by )the imprintsl from the particles of scale rolled into thefsaid surface of said bar. With the use of my machine it is obvious that this cannot occur, the

l bar lbeing passed through my scaling defurnace and not reaching the forming rolls i removed.

l said vice immediately upon emergingfrom the until all ofthe scale has Ibeen thoroughly Having fully described my invention whatQ I claim/as new and desire to secure by Letters Patent,isl 1.
