The purpose of this extension is to pre- 95 two or more ot which are filled with hot palmvent the foaming and boiling oil in the first oil, and in which the lower rollers of two or trough B from rislng and foaming over into more of said pairs revolve, so that the same the next trough B2.

The oil in the last trough B2 will remain entirely placid, as all moisture is freed from the sheet before it reaches the last pair of rolls, so that no moisture or steam can be communicated to the oil in the last trough B3. The oil in this last trough can therefore be and is heated to the requisite high temperature torproduce the most complete and perfect fluxing of the sheet, and also to raise the temperature of the sheet itself to the required pointto produce the best results when it is subsequently immersed in the tin pot. The last pair of rolls and the last oil-trough B3 may thus be and in practice are heated to a much higher temperature than the first pair of rolls and the irst trough B', the middle pair of rolls and trough being heated to an intermediate degree. Each of the compartments B B2 B3 is furnished with an outlet b5, closed by a plug 196, so that the oil may be drawn out when desired.

D D D D D D are three pairs of hollow steam-heated smooth metallic rolls journaled in suitable bearings F F', which are mounted on the frame of the machine in suitable vertical guides F2, so that the upper bearing F of each pair of rolls may be free to move up and down in said guides.

VThe three pairs of rolls D D D D D D are mounted directly over the three oil troughs or compartments B B2 B2, and the lower roll D is immersed for a fraction of its circumference, preferably about one-fourth thereof, in the oil or flux in said troughs. The bearing or journal F of the upper roll of each pairis separated from the lower journal F, upon which it rests, by an adj usting-screwf, so that the rolls may be set parallel to each other and the space between them adjusted so as to admit of the passage of the sheet between the rolls and at the same time permit the rolls to come close enough together after the sheet has passed to practically transfer the flux or oil from the lower roll to the upper one, and thus supply the oil to both sides of the sheet and thoroughly coat both sides thereof therewith. To permit of this slight up-and-down movement of the upper roll of each pair andat the same time keep the requisite pressure between the rolls, we provide the cap-plate F2 of the journal-guide with adjusting-screwsf, which act against a spring f2, that bears upon the journal-box F. By this means the rolls may be allowed to come together or nearly together when there is no sheet passing between them, and thus cause the lower roll to transfer the oil to the upper one and then yield'sufflciently to allow the sheet to pass between them. 2

The rolls D D are all hollow and heated by steam admitted to each pair from the steampipe C through separate branch pipes c4 c5 c6, each furnished with separate regulatingvalves c7, so that the temperature of each pair of rolls may be governed as required. A

E is the feed-table, about on a level with the meeting surfaces of the rolls D D', from whichthe sheets are fed into the first pair of rolls.

E is the discharge-table, preferably arranged at an incline and furnished with a sheet-delivery roll E2 at its inner edge.

G is the oil feed or supply tank from which, 2

through a feed pipe or nozzle g, furnished with a regulating-valve g', the oil is fed or supplied to the troughs B2 B3 in a regular manner, so as to keep the same full and the rollers D D immersed therein to a regular and uniform depth. This oil-feed tank has a steam-jacket g2 for heating the same by steam admitted through the branch pipe c2, the same being furnished with a valve c2 to regulate the temperature.

lfl is the drip pan or tank supported on the frame A below the oil-pot B, the same being large or wide enough to catch drippings from every part of the machine. It is furnished with a well H', from which leads a pipe h to a pump K, which forces the oil up into the supplytank G through the connecting-pipe 7c. The pump K is operated by pitman-rod K, connected to a crank-pin n on the gear N on the driving-shaft N. Y

The rolls D D are driven from the drivingshaft through a set of connecting-gearing N2 N3 N4, the gears N2 being on the lower rolls, the gears N3 on the upper rolls, and the gears N4 on intermediate shafts N5.

The discharge-compartment B4 of the oil` pot B is furnished with an outlet b2, provided with a valve or nozzle 198, through which the oil may flow into the drip-pan below.

rlhe feed-tank G is from time to time supplied with oil to replace that adhering to the sheets passing through the machine, or, if preferred, the fresh oil may be put in the drip-pan H. By means of this tank and its feed-valve we automatically keep the troughs B B2 B3 supplied with oil.

In operation the wet sheets as they come from the water bath are fed between the several pairs of rollers D D', whereby the same are simultaneously dried, heated, and fluXed, the sheets passing out onto the delivery-table E with every particle of moisture driven therefrom, heated and fluxedV and ready to be placed in the tinning or metal coating bath. By means of the steam-regulating valves and the separate branch pipes leading to the several pairs of rollers the first pair of rolls and the oil in the first trough B 'may be kept at a comparatively-low temperature, so that the moisture and steam produced from the wet sheets will not cause too violent foaming and boiling of the oil. of rolls and the oil-trough B2 are heated to a higher degree, andthe nal pair of rollers and trough are heated to a still higher temperature, so that the iiuxed sheet will be delivered from the machine in proper condition to en-V ter the tinning-bath. The rolls revolve continuously, and at the intervals when no sheet is between the rolls the flux or oil will be IOO IIO

The next succeeding pair transferred to the lower roll of each pair to the upper one, so that the oil or flux will be properly supplied to both sides of the sheet. During this operation the overhead feed-tank continuously supplies or feeds the oil to the oiltroughs, thus maintaining the oil at a proper level, and at the same time the pump redelivers the oil collected in the well of the drippan into the feed-tank.

By means of this machine the wet pickled sheets may be very quickly dried, heated, and liuXed without giving any opportunity for the same to become oxidized or tarnished on either side and without waste of the oil or iiuX and without danger of the same getting on fire, the work being also done automatically and without the necessity of hand labor.

The number of pairs of rolls which we pref,- erably employ is three, as-shown in the drawings; but the number of pairs of rolls may be increased or diminished, if desired.

As the oil in the first trough will be in a boiling, foaming, or frothing condition, owing to the steam and moisture from the wet sheets, it will foam up and come in contact with the rst roll D, even though this trough be not full of oil.

As shown in the drawings, the oil-supply tank G delivers the fresh oil only to the last two troughs B2 B3, the single nozzle employeddelivering the oil midway between them on the partition b. It generally is not necessary to deliver the oil from the supply-tank directly into the Iirst trough B', as some foaming up of the oil in the second trough B2 willv take place from time to time in the space Z210 between the-second roll D and the extension h2 of the partition b, and boil or foam over said extension into the trough B', and thus supply said trough with oil. The oil does not foam up over the partition b, as the moisture and steam are mostly driven oft from the sheets by the first pair of rolls and practically all driven off as the sheet passes the second and still-hotter pair of' rolls, so that the steam and moisture are practically confined to the space between the rst two pairs of rolls and the space on the front side of said rst pair of rolls.

By employing a series of pairs of graduated heating-rolls-that is to say, rolls each successive pair of which are heated to a higher temperature than the preceding pair-as the means or instrumentality for drying, heating, and luxing the wet pickled sheets said operations are performed simultaneously or practically simultaneously, so that the sheets have not time or opportunity to become tarnished or oxidized, their surfaces being protected or coated at all times either by the water or by the oil as they pass through the machine, and we thereby secure at the same time the important result of at once preventing undue foaming, boiling, and waste of the oil and the proper heating and thorough Huxing of the sheet, as the wet sheet is first op` erated upon and its water chiefly driven of by the rst pair of rolls at a temperature so low as not to produce violent or undue foaming and boiling of the oil and as the sheet, after being further dried and heated by the next pair of rolls and'their hot oil, is then finally heated to the proper degree and thor' oughly fluXed by the last pair of rolls, the temperature of which may be raised to any desired degree without causing any agitation of the oil in theiroil-trough, and the Workis also done automatically. As the lower heated rolls of each pair revolve directly inthe several oil troughs or compartments, the rolls themselves serve as a means for heating the oil in the oiltroughs and of keeping the oil in the different troughs at the graduated or different temperatures of the rolls themselves, as desired.

The feed-table E should be slightly inclined to permit the Water to continually drain from the wet sheet as it is fed to the first pair. and enters between them, and it should also be made of slats or provided with corrugations in or openings through it to prevent the wat-erfrom adhering to its surface unnecessarily. The object of employing an open or corrugated feed-table and the object of inclining the same are to prevent the sheet from carrying an unnecessary amount of water or moisture to the iirst pair of rolls.

By combining with the oil-troughs with drying, heating, and fiuxing rolls which are hollow and heated by steam admitted to their interior we are enabled not only to heat the rolls to different degrees of temperature, as desired, but also to prevent the oil from catching fire and the waste and danger incident thereto.

We prefer to locate the oil-feed nozzle g between the pairs of rolls and not to deliver the oil directly upon the rolls from this feed-nozzle, as the oil will be more evenly distributed over the surface of the upper rolls by transferring it from the lower ones; but this arrangement may of course be varied, if desired.
