An object of the present invention is to .LOne of'the feedrolls,such'.asindicatedat provide an exceedingly simple 1mann'er of 3, is fixedly secured in the frames land 2 supporting one of a pair offeed rolls so that forrotation bymeansof reduced-hubs 5 and the same may be adjusted to accommodate 6 having keyed to the ends thereof gears? varying, thicknesses of material being fed, d ym ans f @3 8 a d lo, sqflm w i whileat the same time permitting the power the roll 3 is capable of rotation up n impartoperatingflelements to remain in engaged g p wer e ge a dt positi i I i i r 1 1H0"GTI16I1i}. 1 l l Another object ofthe presentinvention is I, The feed roll indicated at aislikewise pro toprovide an adjustment for one ofa pair 'v ded with reduced hubs 11 and 'l2which of rolls which, while permitting adjustment extend through elongated openings lgand 1d of said roll, atthe same timeforces the roll forn ed'intherespective sidejframes 1 and 2, into yielding engagement with the material and to the e'ndof the reduced hubsll andll 0 i being fedbetween therolls. gears 15 and '16 are securedby means of keys 86 v tion is to provide a rolladjustment which can The gears 1 5Aand 16, are so positionedas to it be rapidly andlefl'ectivelyvaried to suit conmesh with the gears 7 and 8 on the feed roll ditions prevailing in the machine, theadj ust- '3 solthat rotatlon of o'neiof thefeed'rolls 1mment being of such a simple character asto parts'rotary motion to the otherfeed roll, it

with bores 25 to re'ceivevthe reducedhubs 11 and 12, which are rotatably supported thereby. Each bearing. block is; provided. on: its inner face with a reduced hub 26 of a length similar to the thickness of the .'brackets"17 :1

and 18, and of a diameter corresponding with the width of the elongated opening 20 in each bracket, so that it is readily seen that the bearing blocks 24 and 24, while capable of verticalmovement or. movement in thedirection of length of the slots'20, are incapable of lateralimovement or movement inthedirection of the width of the slots 20.

Integrally formed withthe bearing blocks 24 and 24 are the upstanding arms 27- and 28 terminating the inwardly directed ears 29 a1 1d,3,0, which are adapted to overlie the ears 21 and22 on the brackets 18-and;18 andin spaced relation thereto, and each" of the ears 29 and 30 are provided with openings 31, which openings are so positionedas to align with the screw threaded openings 23 in the brackets 18 i and 18.

Adjustment ofthe roll, such as indicated at 4, is accomplished by means of bolts 32 and 33 which pass through the aligned openings 31 and 23, and the bolts 32 and 33 are screw threaded at their lower ends so as to thread throughthe openings 23 in the brackets 18 a n;d 18,, the remaining portions of theibolts having smooth surfaces to permit the angular ears 29 and 30 to slide. thereon. Interposed between the angular ears 29 and 30 and the heads of the bolts 32 and 33 are coiledsprings 34 and 35 which normally exert pressure on the angular cars 29 and30 and tend to force the roll 4 into engagement with the roll 3. Itwillbe seenthat by adjusting the bolts 32 and 33 the sprin s 34 and 35 are compressed to a greateror lesser extent, and consequently that the; roll 4 is urged toward the r0113 withgrea-ter or lesser pressure, depending upon the direction ofrotation of the bolts 32, and 33.1

It will further be seen that when sheet material of a thickness greater than the pass between the two rolls3 and 4 is being fed. the roller 4 will automatically adjust itself againstthe tensionof the springs 34. and 35 soas to accommodate the material of greater thickness inthis way, providinga yielding contact'between the roll 4 and the material being fedg From the foregoing itis clearly apparent that the means, for adjusting the roll 4 are provided on the exterior faces of the frames 1 and 2, so that ready access may be had to the adjusting mechanism, and that there is no need for disassembly of any portions of the machine to accomplish the necessary adj ustment, and while I have deseribed'my invention as beingapplicable to the .top roll 4 of the pair, it will be readily understood that the top roll 4 could be fixedly secured and the roll .3 adjusted by similar. mechanism, or

if, it is de'sirable, similar adjusting mechaby forming these parts in the-mannershown the invention can be cheaplymanufactured by well known metalfworking operations such as stamping, swaging or the-like, thereby materially reducing the expense involveddn the production thereof:
