Referring more particularly to Figs.v l to4 of the;
, drawings-wherein, for the purposeof illustration,
is shown a preferred, embodiment of the invention, a pair of rolls I, lie shown, these. rolls being revolubly mounted on spindles or pins2, which, in turn, cylindrical roll holders 5. The-roll holders! are mounted in and supported, by sleeves 5,4whichhave base plates 6 formed integrally therewith-and mounted in slides], the baseplates being;main-.
tained in position in the slides by means of gibs 8;,
The roll holders At are adapted tolbe gripped in the sleeves15, and for this purpose, the sleeves have integrally formed therewith a tubular guide which;

For this purpose, bolts l2 extend-through-Lthe members Land have nuts l3 secured thereto, so that upontightem'ng of the nuts, the surfaces I I of the members II] are brought'torloearhupon the roll holders-to holdthe latter tightly gripped inthesleeves. 7-. i
By mounting th basev plates-'inthe slides 1 in:
' the manner described; they may be adjusted-along the slides to vary-the. spacing'-:of. the 'opposecl rolls lin accordance with the width of thestrip-to;
be beveled.
It will be noted that in the, foregoing silage; menhthe rolls aredisposed in. a substantially Inpsuch, case-,t the angularityhorizontal plane. between the; strip and the rolls; necessary-to pro-: duce beveling of the'strip, is secured by causing the strip: to pass beneath aguide roll ,whose lowermost peripheralsurface is in a plane below larity of the strip with respect to therolls l, the guide roll may-bemovedupwardly. (Jr-downwardly,
and for this purpose,. .a clevi-s boltl-Q, is pivotally I the plane of the surfaces of the rolls I over which; the strip passes. I
The guide roll I4 is mounted on ashait the ends of which are journalled in the arms of a U.-'
sh'aped bracket I 6, pivotally mounted, as at l'l,fon.-

are mounted in the, clevis-like ends 3- of s 5 1 i h l d fi s ment.
nut upwardly, the roll is elevated therewith above the bracket a nut 20. By drawing the nut downwardly, the roll [4 is lowered against the tension of the strip to increase the angularity of the strip to the rolls I.
by the strip tension to decreasesaid angularity.
The aforesaid arrangement means for applying a back tension to the strip to maintain the strip in a taut condition as it is pulled through the rolls. a clamp base 2|, a clamp bar; 22 adjustable relatively to the latter, and strips23 of felt or-the like interposed between the clamp base and bar and between which the strip passes.
Each of the rolls l is provided at its peripheral surface with an annular recess 24, the recess being bounded at one side by a surface of revolution consisting of a conical wall 25, and at the other By drawing further includes V Such means includes with their surfaces 26 inclined downwardly to ward the direction of the strip travel.
The tilting of the rolls for this purpose is accomplished by releasing the tubular gripping members ID from engagement with the holders 4, rotating thelatter to produce the desired tilt of the rolls .1, and then-bringing the members I0 again in gripping engagement with the sleeves.
Under some conditions, the desired angularity may be produced in part by lowering the guide roll; M and in part by tilting the rolls l downwardly in the manner described.
Moreover, it "is desirable at times to bevel a strip by progressive stages, as in producing exside by a surface of revolution in the form of an,
For the purpose of beveling the edge of the strip S, the strip is passed through the rolls, as by'pulling it in the direction indicated by the arrow inFig. 1, with the upper side thereof disposed. against the walls 25 of the recesses 24, "and the lower side thereof whose edges are to be beveled adjacent the walls-26 of these recesses. The rolls I are spaced from each other in such a manner that as the strip is pulled through the rolls in the manner described, the walls 25 of the recesses force the strip towards the opposite walls 26, the flat lower surface of the strip S, as seen in Fig. 2,engaging the Walls 26 as the strip engages the rolls. When the angle which the lower surface of the enteringstrip makes with the plane of the walls 26 of the rolls there results a beveling of the strip which begins atthe'p'oints 21and continues to thepoints 28,
the beveling being accomplished by the sharp edges formed by the intersection of the walls 26' of the recesses with the peripheral walls-29 of the rolls, the strip emerging from the rolls in the condition shown in Fig. 4, i; e'., with theedges beveledias at 30.
- It will be understood the rolls must be properly adjusted to produce the desired beveling of the strip, but at the same timepto avoid concaving of the-strip, which might occur'ifrthe-rolls were too closely spaced. 'During'the aforesaid beveling operation, therolls will be rotated by the strip in the direction indicated by'thearrowsin Fig. I l
It willrb'e further understood that the degree ofbeveling or angle of bevel may be increased by increasing the angle which thelower surface of the strip makes 26 of the rolls, and
with the plane ofthe surfaces that in the case described, this isacc'omplished' by moving the guide roll 14 downwardly.
Inasmuch as the of the strip, instead of by lowering the guide roll. The arrangement of the ---various units of the beveling apparatus, under these conditionsis': shownihFig. 5, wherein th rolls I are shown that the distance between primary function of the guide employed.
In this arrangement, the rolls are disposed with their axes inclined toward each other and in a plane transverse to the direction of movement of the strip. The degree of bevel in this case, is also determined by the degree of inclination of the rolls, the shearing action of the rolls being the'same as produced by the previously described roll arrangements.
It will b seen from the foregoing that the bevel is produced in a neat and expeditious manner, and. that the rotation of the-rolls results in the constant presentation" of new shearinge'dges to the" strip, ours is uniformly distributed about the rolls.
Inth 'practice'of the foregoing methods, it is desired to point out that it is essentialthat the edges formed by the intersection of thewalls 26 of duced until subsequent grindings eventually 'rewhich it wouldbe impracticalto" go.
It is thus seen that we have provided methods for continuously producing accurately beveled edgeso n metal strips, with a minimum of equipment.
Other modes of applying the principle or our invention" may be employed instead of the one duce the rolls to a minimum diameterj'below explainedfch'ange being made as regards the means and the steps herein disclosed, provided those stated by any of the followingclaimsgor their equivalent be employed.
We therefore particularly point tinctly claim as our invention.
.1. The method r beveling metal stn 'a ie the like which consists in ut n i l edge of said surface'to shear sufficient'meta'ffrom so that such wear of the rolls as 00-' maintained in a sharp condition. This can'beaccomplished by sharpa guide for the strip." At
recess can again 'be' ;pro-' at relatively low'cost and passing the edge of the.
strip edge.
2. The method of beveling metal strip and the like which consists in passing the edge of the .strip to be beveled through a roll having a rece s in the periphery thereof, said recess being bounded-by a flat wall and a wall inclined to said flat wall, and causing the edge of the strip to bear with sufficient pressure against said flat wall to cause the edge of said wall to shear sulficient metal from the edge of the strip to produce a beveling of said strip edge.
3. The method of beveling the edge of metal strip and the like which consists in forcing said edge against a revoluble shearing edge, which is revolved solely by the movement of the strip.
4. The method of beveling metal strip and the like which consists in passing the strip in a flat condition through rolls having shearing edges adjacent the periphery of the rolls, and applying back tension to said strip while passing the strip,
through said rolls at an angle to the planes of said shearing edges.
5. The method of beveling metal strip and the like which consists in providing a pair of revoluble rolls having shearing edges, and with the axis of the rolls inclined, and passing the strip through said rolls over said shearing edges, the rolls being inclined inthe direction of movement of the strip. I
6. The method of beveling opposite sides of a metal strip and the like, which consists in providing a pair of spaced rolls having shearing edges, the rolls being. inclined toward each other, and'passing the strip through said rolls over said shearing edges.
7. Means for beveling the edges of metal strip and the like, said means comprising a pair of spaced rolls having their axes inclined toward.
each other each roll provided at its peripheral surface with an annular recess bounded at one side by a conical wall and at the other side by a wall in the form of a surface of revolution formed by revolving a line extending from the inner edge of the conical wall to the periphery of the roll, and at right angles to the axis of the roll, about the axis of the roll.
8. Means for beveling the edges of metal strip and the like, said means comprising a pair of spaced rolls inclined toward each other, each roll provided at its peripheral surface with an annular recess bounded by walls consisting of surfaces of revolution angularly disposed to each other.
9. Means for beveling the edges of metal strip and the like, said means comprising a pair of spaced rolls, each roll provided at its peripheral surface with an annular recess bounded at one side by a conical wall and at the other side by a wall in the form of a surface of revolution 'formed by revolving a line extending from the inner edge ofthe conical wall to the periphery of the roll, and at right angles to theaxis of the roll, about the axis of the roll, means for inclining said rolls, and means for maintaining said rolls in inclined position.
10. The method of beveling the edges of a strip, said method consisting in passing said edges over the intersections of shearing surfaces of undriven rolls which are so disposed as to guide and support the strip edges, and controlling such passage in such a manner as to cause said intersections to apply a shearing action against the strip, thereby removing sufficient material from said edges to produce a beveling thereof.
11. The method of beveling metal strip and the like which consists in providing a pair of revoluble rolls having shearing edges, and passing the strip in a flat condition through said rolls over said shearing edges, said stripbeing passed through the rolls at an inclination to the plane of said shearing edges.
12. The method of beveling metal strip and the like which consists in roviding a pair of revoluble rolls having shearing edges, and passing the strip in a flat condition through said rolls over said shearing edges, the strip beingbent longitudinally as it approaches the rolls so as to cause it to enter the rolls at an inclination to the plane of the shearing edges.
13. In combination, a pair of spaced rolls having edges for bevel-cutting the edges of a strip passed through the rolls, and means for inclining said rolls in the direction of movement of said strip.
14. The method of beveling metal strip which consists in providing a pair of opposed rolls having guide recesses in the periphery thereof and shearing edges adjacent said peripheries, said shearing edges defining a fixed plane, pulling said strip through said roll under a controllable back tension, and controllably deflecting the travel of the strip from a straight line of pull so as to cause the strip edges to enter said recesses at an angle to said plane, and cause said shearing edges to bite into and shear oil a portion of each edge of the strip, the degree of bevel being proportionate to said angle of deflection, and the shearing action continuing throughout the pull of said strip through the rolls. v
