To all whom it may concern:

Be it known that I, SAMUEL E. DIEscHER, residing at Pittsburglnin the county of Allegheny and State of Pennsylvania, a citizen of the United States, have invented or discovered certain new and usefulImprovements in Machines for Cleaning Tin Plates, of which Improvements the following is a specification.

The invention described herein relates to certain improvements in machines for cleaning tin plates of the type or construction embodying a plurality of pairs of cleaning rolls, between whichthe sheets and cleaning material pass, both rolls of each pair being positively driven and one roll of each pair being driven either faster or slower than the other roll. In such machines it has been found the practice to secure the gear wheels" through which the rolls are driven tothe necks or journals of rolls, and hence'inorder-to permit of the rolls being adjusted to compensate for wear, the gear wheels must be constructed as to permit of such adjustment with long teeth, so that when the rolls are new the teeth will intermesh only for a portion of their length. It has been found that the intermeshing of the gears on the roll-journals will exert pressure on-the' latter in a direction to cause the gears and rolls to separate while work is being performed, and hence it has been necessary to positively hold the rolls, as by set screws, as against separation. The rolls being positively held from separation by set screws, constant watchfulness of the wear of the rolls has been necessary to insure eflicient cleaning, for as soon as even a little wear occurs the rolls must be adjusted and adjustments have to be made for different weights and thicknesses of plate cleaned, and other things having to do with the condition of bran.

The object of the invention described herein is to provide such means for driving the rolls as will permit of the automatic adjustment of the rolls as wear occurs, and will permit of a separation of the rolls of a pair, due to the passage of cobbles or'an excess of cleaning material between them and the automatic restoration of working condi tions after such accidental separation. The invention is hereinafter more fully described and claimed.

In the accompanying drawing forming a part of this specification, Figure 1 is a sectional elevation of a tin-plate cleaning ma:

chine embodying my improvement; Fig. 2 isa sectional elevation on a plane indicated by the line IIII, Fig. 1, and Fig. 3 is a detail view of a modified form of coupling.

In the practice of invention, the cleaning rolls 1 and 2 are mounted i'nsuitable bearings 3 and 1, arranged in slots in the side frames 5; these rolls may be constructed in any suitable manner known in the art, 6. 9., both of them made of disks of fabric or one of them is made of s'teel,fas indicated; The bearings of the upper roll 1 are adapted to move vertically in thev slots of the side frames but are yieldinglyheld from" such movement bymeans of springs 6 interposed between the journal boxes 3 of this'roll and the adjusting screws 7. This constructioi'i will permit of the separation of the rollsin case of'the passage between them'of an excess of bran or cobble-,, and the upper roll will be immediately returned to working relation to the lower roll by the springs. The journals or necks of these rolls are provided atone end with coupling boxes 8 for the reception of the wabblers 9 on theends of spindles 10. The'boxes and wabblers may be made of any suitable construction known in the art, permitting of the movement of the rolls without' interference with their driving connections.- The opposite ends-ofthe spindles are also provided with wabblers 11 adapted to engage' boxes 12 on driving shafts 13 mounted in suitable bearings in the sides of the gear housing 15. In bearings 16 in the same housing, is mount-ed a driving shaft 17 on which are secured a gear-wheel 18 and pinion 19, which are adapted to intermesh with two trains of gears, through.

which motion is imparted to the pairs of shafts 13 adapted to be connected, as hereinbefore described, by the spindles to the several pairs of rolls.

By reason of the flexible connections between the driving shafts and the rolls, the latter may be adjusted to any necessary or desirable extent without in any way interferingwith the driving efficiency of the trains of gearing- In case it-should become necessaryto remove the rolls, the gear housing may be slid along its supporting shoes 20 a suflicient distance to-effect the disengagement of one end of the spindles with their coupling boxes, thus avoiding the ne cessity of'dismantling the train of gears or other driving means in order'to remove therolls. I

In lieu of shifting the gear housing as described, when it is desired to disconnect the rolls from their driving mechanism, a spindle formed of separable sections, as shown in Fig. 3, may be employed. In this construction, the wabblers 9 and 11 are formed on the ends of short shaft sections 21, the opposite ends of such sections being provided with flanges through which, and through a spacing block 22, interposed be tween the flanges, the bolts are passed. This construction permits of disengagement of the driving mechanism and the rolls without moving the housing. In order to prevent the escape of bra-n through the slots in which the roll bearings are mounted, same should be closed; one way of doing this is by means of blocks 23 of wood or other suitable material placed in such slots as shown in Fig. 1. These should bemade of a height that will allow clearance for bearing adjustment as shown.

I claim herein as my invention:

1. In a cleaning machine, the combination of a housing, a plurality of pairs of rolls mounted in said housing and adapted to feed and clean sheets between them, a second housing, a plurality of pairs of driving shafts mounted in said second housing, independent of and separated from the first housing, means for driving such shafts at such relative speeds as will effect a cleaning of the sheets, and driving members interposed between and detachably connected to the respective driving shafts and rolls.

2. In a cleaning machine the combination of a housing, a plurality of pairs of rolls mounted in said housing and adapted to feed and clean sheets between them, a second housing, a plurality of pairs of driving shafts mounted in said second housing, one of the housings being movably related to the other, means for driving such shafts at such relative speeds as will effect a cleaning of the sheets, and driving members interposed between and detachably connected to the driving shafts and their respective rolls.

3. In a cleaning machine the combination of a housing, a plurality of pairs of rolls mounted in said housing, the upper member of each pair being vertically movable, resilient means for holding such upper rolls in operative relation to the lower rolls, a second housing, a plurality of pairs of shafts mounted in said second housing, means for rotating such shafts and driving members interposed between such pairs of shafts and the rolls and detachably connected to the respective shafts and rolls.

4. In a cleaning machine the combination of a housing, a plurality of pairs of rolls mounted in the housing, a roll of each pair being moved toward and away from the other roll of said pair, resilient means for holding the movable rolls of each pair in operative relation to the other roll of such pair, a second housing movable toward and from the other housing, a plurality of pairs of shafts mounted in the movable housing, trains of gearing for operating such shafts and detachable means connecting such shafts with the.respective rolls.

In testimony whereof I have hereunto set my hand.
