T 0 all whom it may concern.'

Be it known that I, THOMAS H. MATHIAS, a citizen of the United States, residing at Buffalo, in the county of `Erie and State of New York, have invented new and useful Improvements in Machines for Removing Defective Surfaces of Metal Bars, of .which the following is a specification.

My present invention relates to the removing of defective surfaces from iron or steel bars, or blooms, which have first been worked down more or less from the ingot as de; scribed in my Patent No. 1,120,831 for a p rocess and consists in a machine whereby that process may be conveniently practised. The ingots from the soaking pit show a superficial skin lower in carbon than the body of the metal. As the ingot is worked down and elongated into a bar, by more or less rolling, this skin becomes thinner, but is always present in the finished rail or other product and is a source of weakness. Furthermore as the ingot isrolled out into the bar longitudinal seams develop in this skin extending substantially parallel and are an- To remove this defective surface as the source of these weaknesses I invented my process, and to practise said process l have designed the machine here described.

Certain difficulties attend the removal of such surface due principally to the high temcutting-tools having peripheral teeth, means for rotating said tools at a high speed andV means for feeding the 4bars operated upon to the tools and guiding them therefom. It is also important that the particles ofthe surface, or spittings be guided away fromv the bar and removed from the machine rapidly without danger of welding together, or.

of sticking lto the parts of the machine, or of again coming-in contact with the bar from which they have been removed. To that 'end I have devised means for cooling and 'eX- pelling said spittings without affecting the temperature of the bar, or interfering with the functions of the machine, or with the operation of rolling. It is also desirable to provide means foradjusting the cutters and for cooling the various parts ofthe mechanism. v

Vthereofshowing the nozzles in elevation;

Fig. 5 is a front elevation thereof and Fig.

v6 is a vertical sectional view looking in the opposite direction to Fig. 4. Fig. 7 is a Aview similar to Fig. 1 illustrating a modified form of machine for operating on more than one surface of the bar. Fig. 8 is a front' elevational view of the cutter housing showing theV arrangement of guiding parts, as though taken on section line 8 of Fig. 1 looking toward the cutter; Fig. 9 is a side elevation illustrating the housings for the cutting tools of the machine of Fig. 7 with the cutters and other parts omitted; Fig. 10 is a detail view showing the manner of adjusting the guides. l

1n the embodiment of my invention illustrated in Figs. 1 to 6 l have shown an approved type and arrangement of cutting tool for removing the superficial skin from one side only of the bar. As there shown, the bar` 1 is passed forwardly between the feed rolls 2 2 and 3 3 of the machine and beneath a rotary cutter 4 arranged intermediate of the rolls and above the bar. rlhe bar 1 referred to may be understood as any bar being rolled as for instance a rail which has progressed in the rolling operation about one quarter toward completion. rlhe cutter 4f desirably is rotated at high speed and is provided on its periphery withcutting teeth of suitable formas indicated in Fig. 6, to act upon the bar as it is passed beneath the cutter. I

A supporting roller 6- is jounaled beneath the cutter 4; accurately and rigidly to supportv the bar as it is being cut and this'roller 6 is arranged to be driven in unison with the rollers 2-2 and 3--3 through connections to lbe described. As all of the rolls are of a size they will act uniformly in advancing the bar.

The feed rolls 2-2 and 3--3 are liournaled in suitable oppositely arranged `bearings ',8--8 adjustably supported on standards or Patented New. es, ieee.` y

housings 9-9. The bearings are fitted to suitable ways in the housings and the upper bearings' are supported in the customary manner upon the lower bearings with suitable spacing liners between them. Similarly, the lower feed rolls are arranged to be adjustable by the positioning of liners or distance bars 14 interposed between the housings and the lower bearings. The bearings so spaced and supported are rigidly clamped in position by means of the screw-down boltsl 10-10 provided with hand levers 12-12 and threaded to the housing caps 11-11. Similarly the supporting roller 6 is journaled in bearings fitted within the" cutter or tool housing or standard 16 and adjustable by means of liners 18.

The cutting tool is carried by a tool shaft 20 adjustably journaled and `driven in an improved manner hereinafter described and desirably it is rotated in a reverse direction to the movement of the bar upon which it operates. The removed particles of heated metal or spittings are therefore thrown forwardly of the cutter and an important feature of the present invention consists in the means employed for removing these spittings from the machine without danger of clogging by the welding tendency of thel heated particles and consequent interruption of the properoperation of the machine. The means which l have devised for the eiiicient and successful removal of theheated particles consists in an arrangement of deflection box or chute havlng associated therewith water jets in a manner whereby the particles are intercepted and cooled by the water so that they doI not stick together, and under the impulse of the jets they are ejected from the machine. As the interior of the box is likewise continuously sprayed by the jets there is no possibility of the particles adhering thereto to cause a stoppage from that source. The box is here shown at 25 inFigs. 1 and 2 and is shown in detail in Figs. 3 to 6'.

As best shown inFigs. 3 land 6 the deflection box 25 is open at its front and into this opening 26 the cutter 4 extends whereby the particles removed thereby are thrown directly into the box. The side walls 27--27 and the top wall 28 of the deflection box are arranged to be in close proximity to` the cutter so as to completely receive and retain the particles and at the, bottom of the box there is arranged a hinged baile plate 'dition whereby there is no danger of clogging of the passage.

As will be readily understood the action of the water thus cools and lubricates the particles and also 'ejects them from the .machine without permitting them to freeze to the chute which would interrupt the operation or to cling to each other in which condition they would be diiicult to handle.

The nozzles as shown are suitably flared or flattened and the rear wall of the box is suitably curvedV to deflect the particles outwardly through the chute. The delecting box is suitably supported in position, as shown being bolted to the cutter housing 16. From the-discharge opening of the chute the particles drop into a hopper. whence they may be removed mechanically by anyv suitable means. Y

Suitably supported on the housing 9, in advance of the rolls 2-2, an entry guide 40 is arranged to guide the bars as they enter between the rolls. The'guide 40 is formed with curved sidel guide flanges 41-41 and is provided with hardened metal bearing inserts 42-42 as shown. A top entry guide 43 is pivotally supported at 43 and adjustable by means of a turn buckle support 44 as shown.

Desirable guides are also employed to guide the advancing bar with relation to the cutter and tothe rear feed rolls 3*-3. I

have devised guides therefor comprising suitable guide arms held in position to engage the bar on all four sides whereby it is supported for adjustment with. relation to the cutter. To that end theupperl` guide is pivoted upon a pin 46 and the side guides are pivoted upon pins 47-47; the pins 46 and 4 7 being carried by a supporting frame 48. This frame 48 is itself pivotally supported on a pin 50 carried by suitable brackets of the housing 9. The lower guide 45 is rigidly secured to the frame 48 and is arranged to be engaged from beneath by an adjustable rest shoulder or threaded into a projection of the cutter housing 16. Thus by adjusting of the screw 52 the lower guide 45 and with it tne supporting frame 48 are rocked to adjust the vertical relation of the guide arms to the cutter.

For laterally adjusting .the side guides 45 I have arranged vfor supporting these guides screw 52 bar thereto.

tures in the frame 56 and having nuts 60.

threaded on their outer ends and confined between these nuts and the frame coiled compression springs 61 are fitted to the studs to exert an outwardly directed force on the studs and arms. In consequence the guides are normally held in an outward position. Opposed to the action of the springs 61 I have provided adjusting or set screws 64 threaded to the frame 56`to engage the guides and by theiradjustment accurately to maintain the guides in position. The set screws 64 have squared heads for the use of a wrench thereon and locking nuts 65 are threaded thereon for securing them when adjusted.

The upper guide is supported at its free end to be independently adjustable relative to the lower guide 45 by means of a threaded rod 66 attached thereto at its lower end and received at its upper end in a lug 67 of the frame 16 to be adjustably secured bythe nuts 68-68 threaded on the rod.

The front guides referred to are extended toward the cutter to be in substantially as close proximity thereto as is permissible so as to -insure greater accuracy in guiding the Similarly constructed but reversely arranged guiding parts are provided to the rear of the cutter of which rear guides 145 are forwardly extended from a frame 148 to be in guiding engagement with the bar at their forward ends immediately behind the cutter. The frame 148 is similar to frame 48 and is similarly supported upon a pin 150. Likewise the lower guide arm 145 is carried on the bracket 148 and has thereon the frame 156 corresponding to frame 56. The upper guide 145 is pivoted on pin 146 carried in the bracket 148 and the side guides 145 are adjusted in the frame 156 in similaf" manner to the adjustment of the side guides 45 in frame 56 described but these ,rearward side-guides, as shown, are extended rearwardly between the rolls 3 and pivoted upon vertical pins 147 carried by a supporting bracket 150. The side guides 145 being long and pivotally supported at the front may be adjusted in and out without `substantially changing their angle to the work.

6 are driven in unison and the cutter preferably is driven independently thereof. The rolls are driven from a suitable source as the motor 75 indicated, through connections here shown comprising a drive-gear 76 on the motor shaft in mesh with a gear 78 on suitably journaled counter-shaft 79. Upon shaft 7 9 is a small gear 80 in engagement with a larger gear 81 on shaft 82 and the power is transmitted directly from this latter shaft to the rolls 2. For that purpose the shaft 82 is arranged to be in parallel alinement with the upper of the rolls 2 and is coupled thereto by a suitable coupling 84. The shaft 82 is journaledat one end in a standard 85 and beneath it within the same standard, is journaled a shaft 86 parallel to the lower ofthe rolls 2 and coupled thereto by a suitable coupling and the two shafts 82 and 86, are rotatably connected by gears 88-89 on the respective shafts by means of which the lower roll is driven. A similar manner of driving the rear pinch rolls 3-3 is employed wherein upper and lower shafts 90-91 are journaled in va standard 92 and rotatively connected by gears 93 and are arranged in parallel relation to the upper and lower pinch rolls respectively and connected directly thereto by suitable couplings 05. A connecting shaft 96 is suitably j ournaled at right angles to the shafts 82 and 90 and has afxed thereon ruiter gears l(1T-98 in engagement with similar gears 99-100 respectively on the shafts 82 and 90 whereby the lattershaft is driven from and in unison -with the shaft 82 and the forward and rear ward feed rolls are given a like rotation. A corresponding movement isimparted to the supporting roller 6 throughthe engagement of the miter gear 102 with coacting gear 103 on a roll drive shaft 104 journaled in parallel relation to and coupled with the roller. A desirable' arrangement of the rotary cutter is, as shown best in Fig. 5, with the circular cutting tool 4 clamped by annular flange 106 to a suitable cutter disk 107 keyed onto cutter shaft 20. The shaft 20 is journaled in bearing blocks 108 fitted to vertical ways in the opposite standards 109 of housing 16 and at its other end is similarly journaled in bearings tted to ways in opposite standards 112-112. Between the standards 112-112 the cutter shaft 20 carries a fixed pulley 115 driven from a drive pulley 118 on the axle of a driving motor 120. The driving power is thus communicated from the motor to the cutter whereby the latter is driven preferably at a high speed. l

The bearing arrangement of the cutter shaft provides for simultaneous adjustment of all of the bearings 108 and the similar bearings in the standards 1'12-112 (not shown) vertically within the standards so as to shift the cutter therewith when deported upon suspended .supporting vrods- 122-122 as best shown in Fig. 9. relhese lrods 122 are passed upwardly through the cap 16 ofthe housing 16 and have threaded on their upper ends the nuts 124-124 beneath which are arranged the coiled compression springs 125 fitted to the rods. The springs 125 are thus confined between the nuts 124 and the cap 16 to rest upon the ylatter for supporting the cutter bearings 108 which rest upon supporting keys 126 carried by the rods. Adjusting of the bearings is directly effected by means of threaded adjusting rods or stops 127 threaded to the caps 16 to bear upon the upper surface of the bearings and thereby determine the position of cutter. All of the bearingsl for the cutter shaft are supported in the same manner and are arranged to be simultaneously adjusted by connections now to be described.

Fitted to the upper end of each of the adjusting rods 127 is a bearing bracket 128 providing horizontal bearings for an elongated adjusting shaft 13() horizontally supported in the bearingsso provided. This adjusting shaft 130 has affixed thereon small bevel gears 131 in engagement with gears 126 aixed to each of the adjust-ing rods 127 whereby upon turning of the shaft a like rotative movement will be imparted to each of the adjusting rods -to adjust its related bearings and upon one end of the shaft 13() is provided a hand wheel 132 to `conveniently effect 'this adjustment,

At points"134 and 135 (Fig. 1) water jets are directed against the active surface of the cutter to prevent adhering of the heated metal thereto and the water, which is introduced in sufficient volume for that purpose, also has a desirable cooling action on the cutter whichcontributes to the successful operation of the machine. A suitable .pro-

tective hood 136 is supported above the cutter as shown. The lowermost jet 135 also performs an important function of cooling the particles and wetting them and also the baille plates so that the particles do not adhere to the latter'. i

While the machine described employs but a single cutter for removing the superficial skin from one surface of the bar only it will be readily understood that a plurality of such cutters may be employed simul,

taneously to operate upon two or more surfaces of the bar if desired.` In Fig. 7 I have shown such a machine wherein the supporting roller 6'of the machine irst described is replaced by a second cutter 4 arranged to operate upon the under surface of the bar as shown. This lower cutter may be driven in any desirable manner not necessary to be shown.

This lower cutter may be driven from any source of power not necessary to be shown. 1t is here shown carried by a cutter shaft 20 arranged to be adjustable by being supported in similar manner to the support of the upper cutting tool 4. Referring to Fig.

, 9, 108. indicates one of the bearings for the cutter shaft 20', these bearings operating in the guide-ways of the standards. The adjusting connections provide for adjusting the bearings 108 from beneath and comy rlhe springs 125 are confined between nuts 124 threaded onto the rods 122 and washers 126 received on the lower ends of the upper rods 122. The bearing arrangement for the lower cutting tool isthus generally similar to that for the upper tool whereby it may be adjusted with reference to the bar upon which it acts.

A deiection box 25 is associated with this lower cutting tool for ejecting of the particles removed from the bar and may be in the form of a curved hood, as shown in Fig. 7, to deect and discharge the spittings downwardly beneath the cutter. At 35 is indicated the nozzles for directing the jets of -water `into the deection box to intercept and cool the particles and lubricate the sides of the box in the manner described. At 30 l have indicated a suitable resilient the bar and guide the particles into the boxl 25. The position 'of the nozzles 35 is such that the jets therefrom will impinge both on the baille 30 and on the teeth of vthe cutter 4f whereby they are lubricated to the end of preventing the particles adhering thereto.

While the process of my said Patent No. '1,120,831 was intended to be practised in any manner that might be desired without reference to any particular machine, yet the machine Ahere described is particularly adapted to the practice of said process. By means of this machine the surfacelmay desirably be. cut from blooms and bars of various sorts. This machine has proved successful in practical use for a considerable pe.- riod and is particularly adapted-for use in connection with the production of different A the scope of the appended claims without departing from the spirit of my invention.
