APPARATUS Fon UTILIZING WASTE AND SCRAP rMETAL IN TrIr:- PRODUCTION orY Y' COMMERCIAL BARS Applicationled October 8,.1929. Serial No. 398,130.

This invention relates to the util-ization of waste or scrap metal such as steel beams of various kinds, metal tubing, etc. to produce bars, rods and various structural shapes and 5 the like, and it includesan apparatus as well as a novel method or `processy whereby substantial metal elements, ordinarily treated as waste or scrap, may be vcut into elongated,

fiat pieces in a cold condition so as to beusalf' ble in that condition or to be converted by heating and rolling into commercial rods,

bars or various structural shapes, as well as various other purposes. c

` One object of the invention is the provi- 15 sion of an apparatus which will carry out my method or process of cutting the metal while in a cold condition in an eiiicient and expeditious manner, the resultant parts being available for cutting, slitting and rolling treat- L' ment for conversion into various commercial forms with a minimum expenditure. of time, labor and material.

The apparatus of thisinvention provides a draw bar in association with rotatable cutters :2:- vwhereby a metal element is drawn through the cutters to be severed while 1n a cold condition, suitable mechanisms being provided for properly holding and guidingthe metal element until the cutting operation is complete. n v

To rthe accomplishment of the foregoing and such other objects as may hereinafter ap'- pear, this invention consists inthe construc A jtion, combination and arrangement of parts 3" hereinafter described 4and then sought tobe delined in the appended claims, reference beingh ad to the accompanying drawings forming a part hereofnand which show, merely for u, the purpose of illustrative disclosure, a pre` ferred embodiment of myinvention, it being expressly understood, however, that various changes may be made in practice within the scope of the claims withoutdigressing from my inventive idea.

In the drawings Y kFigure l is a vertical longitu of an apparatus constructed dinal section to embody my l invf-intion and carry out my method and procv 50 ess.

l transverse cross section taken substantially on line 6 6 of Figure l.

I have elected in the accompanying drawl ings and in the following description to disclose my invention as adapted to treat or cony'ert I-beams and other similar structural shapes into elongated elements or parts suit-, v able for conversion into various commercial` forms; itis to be expressly understood that the invention is not to be restricted to treat-v ing this class of material only, but that the apparatus and the method is adaptable to treating and handling other forms of metal.

` Referring now tothe drawings l designates a housing of any suitable or appropriate form and 2 and 3 designate shafts supported and mounted in said housing, adjustment being provided by the screws 4 operating journal boXes 5 for the shafts. Cutters 6 are secured to each of said shafts in opposed relation. The forni of cutters shown is of disc shape with kthe bevelled cutting edge Y and attached to the shafts by means of the :unitary hub 8.'v For slitting an I-beam i 9 such as illustrated, by way of example, it is rnecessary to use two sets er pairs of such l cutters, two on the top shafta'nd two on the lower, and to adjust thesecutters on the shafts so as to cut orslit the web l0 'of the beam` 9 asclose as possible to the flanges 11 thereof. AThis almost entirely eliminates a' rib or web unitary with the flanges when the latter are separated from the web and thereby produces iianges Without a rib and also 'a fiat plate member of the maximum width from the waste or scrap metal element.

As lshown in Figurel of the drawings, the shafts 2 and 3 are parallel and spaced apart a sufficient distance to enable t le draw bar 12, to be presently described, to move freely in the space between said shafts and also between the two pairs of cutters. These cutters are fiXedly and adjustably secured to the shafts so as to rotate therewith and perform the sole function of slitting or grooving the metal. 'To that end they are mounted idly so that they do not operate to feed the metal, the feed being accomplished by the pull of the draw bar 12 on the rear end of the metal element being treated.l

In the feeding` operation this nieta-l element 9 is supported for proper movement upon a plurality of transverse rollers 13 suitablymounted between elongated frame members 14. These rollers are mounted in such a position as to support the metal element 9 by its flanges to present the same properly tothe cutters for the cutting action, This has reference to the yhorizontalplane of operation. Of course, it is necessary that the metal element be presented to the cutters in proper line or in proper alignment and to that end I provide a feeding carriage 15. This is supported by grooved wheels 16 to move freely and idly along the tracks 17 which may be formed as part of the frame. This carriage carries on its under side a pair of clamping and holding arms 18 pivotally mounted to the carriage as at 19 and provided on their outer ends with the rounded holding or engaging members 20. As indicated in dotted lines, these arms are adapted to be moved from open to closed position simultaneously and to the same degree. 'hese arms engage the sides of the metal element 9 being treated and, therefore, position the saine centrally of the apparatus and in proper alignment to the cutters. In order to accomplish this simultaneous and uniform movement of the two arms 18, I provide elongated screw member 21 suitably supported beneath the ca riage and having boi; menil `bers 22 provided with screw-threaded portions V23 to engage the right and left-hand threads of the screw 21 and to be moved there by in opposite directions and to the saine degree when the screw 21 is rotated. These box "y membershave Tshaped guiding elements 24 connected thereto which slide between the spaced guides 25 suitably secured to the under side of the carriage so that the box meinbers will always move in a straight line transversely across the carriage. To each guiding element 2a I attach angular braclret 26 having a horizontal flange 2'? to receive the pivot element 28 which connects the rear or inner end 29 of arms 18 to said bracket 2G and, therefore, to saidA sliding box membei- 22. It is seen, therefore,vthat by rotation ofA the screw 21 the arms 1S will be opened and closed simultaneously and uniformlyV whenever necessary. These parts are operated .to clamp the sides of the metal element 9, be-

ing treated, with suflicient friction so as to move or pull the carriage as a whole along with the metal element as it passes through the cutters.

rIhe draw bar 12 is connected to a suitable travelling carriage 30 on which is pivoted a dog V31 which is' adaptedV to engage the links of a chain 32 suitably mounted and driven on the draw bench 83. This dog'lias the projecting arm Sil-which isadapted to engage the trip member 35 when the draw bar reaches the outer limit of; its movement soasto automatically release the draw bar from the driving chain.

'It will be understood that in slitting metal shapes of this character the side flanges will have a tendency toliare or bend outwardly and take up a considerable space. In order to prevent this I provide the guiding carriage S6 which is supported upon grooved Vwheels 37 to run upon the trac 'rs 38.' The carriage is in the form'of a channel 3,9l of suhicient width to support metalelenients of the maximum size and having the side flanges l0 of sufficient height to properly hold the spreading and bending side port-ions, as indi-v cated in ligurel2 of the drawings'. In 'operation, this carriage is positioned adjacent the cutting discs .so that when lthe flanges of the metalel'ement arevrseveredand spread outwardly, the ends thereof will engage the side flanges 40` of theV carriage 36 .and move the carriage along its tracks 38, whereby the 'carriage constitutes a movableholding means, for the severed flanges of the metal element. The side flanges ofl the carriage are formed or provided with grooves or-recesses or projections orv any suitable form of irregularity against which the ends ofthe out material engage so asto positively move the carriage. In starting the operation, the beam 9 is placedV upon the transverse rollers 13 andthe draw bar 12 is connected to the rear end of the same, the arms 18 being clampedagainst the sides of the rear end of the beam. Power being applied toA the draw bar, the bar is moved into Acooperative relation to the cutters andthe side flanges severed therefrom, the carriage 15 moving along with the I-beam. Thesevered flanges spread out and cause'the movement fof the carriage 86 as previously described;

The cold metal is moved between the rotary cutters by a travelling draw bar attachable to the metal, said draw bar acting solely to draw the metal with a travelling motion between `the rotary cutters. The cutters are idle in theirmountings and they are rotated `o-n-.their axes by frictional engagement with the idle motion ofthe rotary cutters, and saidk pulling means imparts motion tothe draw bar with respect to bot-h the rotary cutters and to the pressure mechanism. The drawbar is attachable either to structural shapes or compacted tubes orto any other kind of preusedcold metal adapted for treatment .in thev machine; infact, the draw bar operates on metal of any appropriate character-and independentlyof the adjustments orpositions or the rotary cutters in adapt-ing them for service on diverse 'characters of metal to be slitted and separated.` A .Y In my invention I do not use rolls for eii'ecting the feed motion of the metal. F or cutting' reliance is placed upon disc-like c itters spaced relatively to each other on a sha ft with which the cuttersiare rotatable, and this shait is mounted for rotation idly in` appropriate bearings of a housing. It is preferred to usel two sets of rotary cutters, the cutters ofeach set being above and below the path of the moving metal, and the two sets of cutters are spaced relatively to each other on the respective shafts. rIhe shafts are relatively adjustable to accommodate the cutters to metal of varying cross sectional sizes,`and said cutters are .shiftable on the shafts to regulatel the distance between parallel slits produced on the metal by the rotary actionof the cutters, whereby the cutters may be changed in positions to suit the material to be operated upon and which adaptation is effected regardless of the feed motion to be by the travel of the drawV given to the metal bar. v 1

As shown-in Figures l and2, I provide means for supporting and guiding the web of the I-beam passing through this apparatus. This means includes the transverse bar 4l which is connected to and supported by housing 1. Mounted upon thisbar 4l are a plurality of spaced arms 42 extending rearwardly therefrom and having their ends curved or arcuate in shape as at 48, to lit over a cylin The top surface of these bars is of substan-A tial extent so as to support the web 10 vespecially after the flanges 11 are severed there-*- from. A holding and positioning member is provided above these guiding bars in the form of a channel shaped member 44 havingV its rearward Vend extended beyond the plane of the axes of the slitting discs and slightly turned upward as at 45 to receive thefwebv l() thereunder and between members 42 and 44. This member 44 is adjustably held inl position by means of the screw element 46 -connected to the yoke member 47 slidably mounted upon the angle member 48, which' isconnected to the opposite housings l; `Mein ber=44 is, therefore, adjustable sidewise and also may be raised and lowered, depending upon the thickness of the web. Members 4Q are adjustable sidewise and with relation t'o drical spacer between the cutting discs;

each other. This provides a verysimple and effective means of supporting-the web and preventing it from curling up orbeing deformed in the operation of the machine.
