rvwilyszsz 2 The shafts llof the. upper rolls 15, 15, 3

l5". and 15, are mounted in housings 16, which rest upon the opposite upper longitudinal liars 2* of the frame.

slots 2 are formed in the bars Longitudinal to receive Q the depending heads ot bolts 17, which pass lower rolls, means for ad usting the lower through the housings 1t and are secured at the top hy nuts tts'. It is thus apparent that by loosening the nuts 13 of any pair at housings It). said housings and their roll-shaft and roll may he moved longitudinally of the apparatus, and independently of any other roll. In order that tlt'll pair of housings 16 may he moved together, it is preferred to connect them together. as by webs 19.

The upper roll-shatts and rolls may also each be made vertically adjustahle. in any well known or suitable way. The shafts are herein shown as journaled in blocks 20, carried by screws ll 'rotatahly mounted in the housings 1(3 aml provided with hand-wheels 22. In order thatthe vertieal adjustment of hoth ends of each roll-shaft may he evenly accomplished by turning either hand-wheel, the shafts of each pair of screws 20 are provided with sprockets 23 connected by chains 2 t.

It is obvious that the numher of rolls used maybe varied, as well as that the upper rolls might be driven, and many other changes may he made by those skilled in the art without departure from the spirit of the invention. Also the apparatus may housed for bending, as well as for straightenin", pieces of metal.

By making the rolls adjustahle hoth vertically and longitudinally of the apparatus, it is obvious that pieces of metal of widely varying thicknesses may he effectively straightened, and the apparatus is thus given a much greater range in working capacity than any with which I am aciplainted. Also by the independent adjustment of individual rolls, the apparatus is rendered very flexible, and the relative positions of any of the rolls may be qnicldy altered to suit varying eonditions.

I claim as my invention:

1. In an apparatus for straightening metallic articles. the. combination with a series of lower rolls, of a series of upper rolls,

BEST AVAILABLE COP? ently of each of the other rolls of said series,

and means for adjusting each of the rolls of one series in a horizontal direction independently of each of the other rolls of said last-mentioned series.

3. In an apparatus for straightening metallic articles, the combination with a series of upper rolls adjustable horizontally in a line at an angle to their axes, of a series of rolls horizontally, and horizontall adjustable means for driving the lower ro ls.

l. In an apparatus for straightening metallic articles the combination with a series of lower rolls, of a series of upper rolls, means for adjusting the rolls of the upper series vertically, independent means for adjusting the rolls of the upper series horizontally in a line at an angle to their axes, and means for adjusting the rolls of the lower series horizontally.

5. In an apparatus for straightenin metallic articles, the combination with a ame and a series of rolls mounted therein, of a series of housings mounted on the frame, means for adjusting said housings longitudinally of the frame, rolls mounted in said housings, and means for adjusting said last mentioned rolls in lines at righbangles to that of the adjustment of the housings.

6. In an apparatus for straightening metallic articles, the combination with a pair of rolls having their axes in parallel rotation, of a third roll having its axis parallel to those at the otlfer rolls and arranged between but out of line with said pair of rolls, means for adjusting said third roll in a line at right-angles to the common lane of the axes of said pair of rolls, and in epen'dent means for adjusting said roll in a line parallel with said common plane.

'7. In an apparatus for straightening metallic articles, the combination with two series of rolls mounted on two series of roll-shafts ha ring their axes arranged in parallel planes, of means for adjusting the rolls of one series in the line of its plane, means for adjusting the rolls of one series at right angles thereto, and me: us for driving the rolls of one series.

8. In a machine for straightening metallic articles, the combination witlrtwo series of rolls having their axes arranged in parallel planes, of means for adjusting each roll independently of the others in the line ofthe plane of its series and in a line at right angles thereto, and means for driving the rolls of one series.

In testimony whereof I have hereunto se my hand.
