To all whont it ntcty concern:

Be it known that weflVILLIAM PRIcE LEWIS and THOMAS REESE WILLIAMS, citizens of the United States, residing at Canton, in the county of Stark and State of Ohio, have .in-

vented a new and useful Improvementin.

Catchers for Tinning-Machines, of which the following isa specification.

- The invention relates to means for catch ing metal sheets as they emerge from-a..plat ing or tinning machine and for delivering the same to a receiving or carrying-off table; and' the object of the improvement istoefficiently perform these functions Without the aid of manual means and to do so Without injuring,

defacing, or destroying the-sheet or the coat-- mg on the sides thereof.

' tained bythe construction, mechanism, and

arrangement illustrated in the accompanying v drawings, in which" Figure 1 is alongitudinal section of atmlning-ma chine, showing a catcher applied thereon, on line 1 1, Fig. 2; Fig. 2., a plan View of one form of the catching-rolls; Fig. 3, a plan view of an alternate form of the rolls;

and Fig.4, a fragmentary section on line 4 4,

Fig. .3, illustrating the middle bearing-bracket for a divided roll.

Similar numerals 'refer to similar parts throughout the drawings. f

The tinning-machine illustrated is of an or dinary type and comprises the vessel or. tinning-pot -1 with various compartments for v the 'flux 2, the molten tin-bath 3, and the fin- I through the flux and tin-bathbetWeen the guides 1 and are so directed by these guides that when they emerge from the bath into the finishing-oil they are caught between the lower pair of tinning-rolls and are passed between them and then on and between the two succeeding pairs of tinning-rolls, from the upper pair of which they emerge with the proc-' ess of plating or tinning completed, but with the coating of tin on the sides ofthe sheets in a somewhat soft condition andsusceptible This object is atby contact The'length of to being damaged or defaced a hard or foreign substance.

the tinned sheets isusually suchthat theymust be caught as they emerge fromth'e tinning -rolls before the coating of tin is cooled.

sufiicientlyto permit their being. caught between rolls or disks having very hard gripping or contact faces, as of steel or other similar hard material.

A pair of rolls preferably composed of a sei I ries of adjacent collars or disks 6 on the shafts,

-7 are mounted, preferably, directly over the. tinning-rolls, the peripheral parts of which.

disk rolls are made of solid tin or other suit able relatively soft material, and a' convenient manner of making these disk rolls is to cast.-

thedisks on a tubular'shafthaving apertures 8 therein, into which a 'e'rtures the tin of the disk will-adhere, as s own-at 9 in Fig. 2,:

These ,disk rolls are preferably made of the same diameter as the tin-rolls and are geared to rotatein unison with them but they may be made slightly larger in diameter than the tinnin'g-rolls, so that when rotated in unison with them the disk roll swill have a sli 'htly-' faster peripheral s eed and will acce erate.

rather than retar the movement of the sheetswhen they leave the nip 0f the rolls below.

' The disk rolls may also be made of the sep i ar'ate collars 6 fastened on the solid shafts '7" and 7 b by means of the flanged and threaded sleeves'10, which are fixed at theproper places on the shafts, and the'flanged nuts 11, which are secured on the-sleeves. The shafts of the disk rolls are journaled in' the bearings l2,-mounted in suitable housings 13, which are supported on and near the sides of the tinning-pot. Y elongated,so that the bearings-ofone shaft can be adjusted With reference to the bearings of the other shaft, Which adjustment. may be made by the ordinary set-screws 14,

turned through the ends of the housings, and when it is desired-to cushion the contact of the disk roll's against the tinned sheet the.

spiral springs 15 may be-used around the inner ends of the set-screws and arranged to act between theadjusting-nutslfi on the screws and-the adjacent bearings, in which latter event the set-screws do not abut di rectly against the bearings, and when the catcher is used on a double or jumbo ma- These housings are preferably -IOO chine, wherein two series of sheets are handled, one each side of the tinningot, the

adjustable shaft may be divided in t e middle and the adjacent ends thereof independently journaled and supported in the'respec- 5 tive middle bearings 12*, mounted in the housing 13, which is securelyattached to the tinning-pot at or near the median line thereof, and these middle bearings maybe adjusted and cushioned in the same manner .1 as described for theend bearing.

For the purpose of directing a tinned plate I 'on the tinning-pot in front of the catching rolls and extend upward and backward over the same, so' .that as the sheet emerges it is always deflected to the back side vof. the machine, and for the purpose of preventing a kinking of the sheet by its being deflected or bent too far by its weight as it emerges from 2 5 thec'atching-rolls the bar19 is mounted over the rear side of the catching-rolls, and this bar constitutes asupport 'ovenwhich the- --shee"tifallsj whenrfed out of amachine. This 1 bar iscorrveniently mounted by being passed through i the apertures 20 in the ordinary posts 21, fastened on the housingsof the machine. By providing'several of such apertures, the rod can be adjusted to various heights for properly. sup ortin plates ofdif- 35. ferent lengths. The inclined c ute 22 isprpvided leading. from the back side of the ma: chine, onto which chute the sheets drop'and' will slide down on a carrying-off table or other fern'i; of conveyer, (not shown,) and 40- this chute'frnay be hooked over the supporti .bar,as illustrated. g

he catdhing-rolls. are preferably located some'sixteen or more inches above the upper pair of tiiming-ro'lls,"so that when the newly- 4 5 tinned e f-meet in caughtbetween them the coating is cold and. hardened .to such an extent that the com aratively, soft material out of which the dis rolls are made'does notinjure, deface, or destroy the coating or the body of 5o the sheetin any manner. Acertain amount of the finishing-oil is carried up with each sheet and accumulates on the periphery of the disk rolls, with the result that the sheet is usually somewhat smeared with this grease 5 5 along the path of the disks;'but this mark of grease is removed by the usual branning and polishing prdcess by which the tinned sheet 1s cleaned.

It will be understood that the periphery of 6c the, catching rolls can be made of some other suitable soft material than tin, and that the width of the disks can be increased at will even to the extent of making a solid tin roll; "but we prefer to use the comparatlvely narmeg-see row disks for the saving in the solid tin required, and also for the greater freedom given to the sheet for cooling.

We are aware that adjacent rolls have been used to conduct and convey sheets gasi the steel-finishing rolls in the machine shown, and of course do not claim the means for per- .forming this function in itself; but we are not aware that such rolls have heretofore been adapted to successfully catch and convey newly-tinned sheets without permanently.

defacing the coating of tin thereon, and it is the means for performing this. function with reference to the effect on the object acted upon, without injuring,'defacing, or destroying it, that we believe to be new and useful.

, and de- What we claim as our invention sire to secure by Letters Patent, is

1. A catcher for a tinning-machine comprising a pair of rolls having their peripheral parts made of tin.

2. A catcher fora tinning-machine comprising a series of adjacent short rolls having their peripheral parts made of tin.

3. A- catcher for tinning-machines comprising a pairof positively-driven rollers having gripping portions provided with tin to prevent marking of the plates. 7

4. plate-catcher having positivelydriven catcherrolls, said rolls having-separated registering gripping portions of tin.

5. In a plate-'catcher, a pair of driven feedrollers above the tinning-machine, and having tin-gripping portions, one of the rollers being-divided in the middle with means for yieldingly pressing each divided part'toward the other roller.

6. In a plate-catcher, a pair of driven feedrollers above thetinning-machine and having tin-gripping portions, one of the rollers being divided in the middle, with means for adj ustin each divided, part with reference to the ot er roller.

7. Ina plate-catcher, a pair of driven feedrollers above the tinning-m'achine, and having soft gripping portions, one of the rollers being divided in the middle with means for yieldingly pressing each divided part toward RiALPI-I L. YALEY.
