JOHN C. TALIAFERRO, OF BALTIMORE, MARYLAND, ASSIGNOR, BY MESNE ASSIGNMENTS, TO AMERICAN CAN COMPANY, OF JERSEY CITY, NEW JERSEY, A CORPORATION OF NEW JERSEY.

MACHINE FOR DRYING AND FLUXING METAL SHEETS.

SPECIFICATION forming part of Letters Patent No. 722,643, dated March 10, 1903.

Application filed November 24, 1900. Serial No. 37,600. (No model.)

To all whom it may concern:

Be it known that I, JOHN C. TALIAFERRO, a citizen of the United States, residing in Baltimore, in the State of Maryland, have invented a new and useful Improvement in Machines for Drying and Fluxing Iron, Steel, or other Metal Sheets Preparatory to Tinning the Same, of which the following is a specification.

My invention relates to fluxing-machines used in the manufacture of tin-plate.

It consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown and described, and specified in the claims.

In the accompanying drawings, forming a part of this specification, Figure 1 is a side elevation of a machine embodying my invention. Fig. 2 is a plan view, and Fig. 3 is a central vertical longitudinal section.

In the drawings, A represents the frame of the machine.

B B are the drying and fluxing rolls, the same being hollow and steam-heated through the steam-pipes O O by which steam is admitted to the interior of the rolls.

D is the feed-table, the same having a series of converging rails 61 (1 upon which the sheets are placed and which operates as the sheets are pushed forward over the same to partially scrape the water from their surface, owing to the fact that the rails converge or extend at an angle to the direction of movement along the feed-table. The feed-table is further provided with side guides or gages d (1 one of which, d is adjusted to and from its fellow d by means of the brackets d furnished with a series of notches or holes 01 in which fit pins 61 by which this adjustable gage is secured in place. These converging rails d on the feed-table serve to partially free the sheets from the water adhering to their surface as they are taken out of the water bath or vessel E and placed upon the feedtable.

The metal sheets are fed forward into the bite of the first pair of rolls B by means of a vibrating feeder, preferably consisting of a series of fingers F, secured to a rock-shaft F,

which is rocked at intervals, as required, by

tact with the water.

means of cam f, through the lever f and link f which connectswith the arm f on the rock-shaft.

G is the flux bath or vessel, the same being furnished with a trap-discharge g, the upper end or leg g of which extends above the bottom of the vessel sufficiently to prevent the palm-oil or flux from flowing out,while at the same time it'terminates sufliciently below the upper edge of the vessel to permit the water which collects in the bottom of the flux vessel from the wet sheets passing through the machine to automatically discharge, the water of course bcin g heavier than the oil and separatingtherefrom. The outer discharge end g of the trap extends up to a less height than the level of immersion of the rolls in the flux to keep the rolls from coming in con- The flux vessel G is supported by hooks g g from rods 9 on the frame of the machine. The hooks g are spring-hooks to enable the vessel to be conveniently unhooked at one end when it is desired to empty it. Beneath the flux vessel G is a collecting vessel G for overflowing oil and water, the same having an upper faucet and K is a curved connecting-chute for despout-shaped flux vessel M, open at both ends and projecting at its lower end into the molten tin 7c in the tinning-pot K and extending sufi'iciently beneath the surface of the molten tin to enable the comparatively small amount of flux in the vessel M to stand at considerable height above the surface of the molten tin without spreading over its surface or causing the molten tin to overflow the pot K or rise to too-great height therein, this action or operation being due to the great difference in specific gravity between the molten tin and the palm-oil or other flux. This secondary narrow or trough-shaped fiuxing vessel M thus combined with the tinning-pot operates, in connection with the fiuxiug-rollers D D and their flux vessel G, to insure the complete and perfect fiuxing of every portion of the entire surface of each and every sheet passing through the machine, as well'as to completely expel from the surface of the sheet all water or moisture. This combination of parts also prevents all danger of and obviates all trouble from the flux on the molten tin in the tinning-pot foaming orboiling over and catching fire, as has heretofore been experienced where the flux on the molten tin is permitted to spread over the Whole surface of the molten tin in the tinning-pot. The secondary open-ended fiuxing vessel M has an overflow spout or passage M near its upper end for the surplus flux collecting therein from the fluxed sheets as they pass into the tinningpot. This overflow-discharge spout M projects over the collecting vessel G, into which the surplus flux is discharged. The secondary or supplemental fluxing vessel M is also provided with curved or inclined guide-bars N, which are hooked onto its upper edge and serve to direct the metal sheets centrally and properly into the tinning-pot from the curved connecting spout or chute K.

P is the driving-shaft, having a drivingpulley P and suitable gearing p p communicating motion from it to the fiuxing-rollers D, and the cam f, which operates the feeder, receives its revolving movement from one of the fiuxing-rollers through the connectinggearing p p. The gearing p 19 preferably comprises a pair of bevel-gears, connecting spur-gears, sprocket gears and chains, as indicated in the drawings, and the gearing pp' preferably consists of sprocket gears and chains.

I claim- 1. In a fluxing-machine, the combination with revolving, steam-heated fluxing-rollers, of a fluxing bath or vessel in which the lower fluxing-rolls revolve, a feed-table having converging rails for supporting the sheets and a feeder for pushing the sheets on said rails, a counter mechanism, a counter-arm projecting in the path of the sheets,a tinning-pot, a secondary contracted or spout-shaped fiux vessel, open at both ends and projecting at its lower end into the (inning-pot, a curved chute for delivering and directing the sheets from the fiuxing-rolls into said secondary fluxing vessel, a collecting vessel, an overflow discharge-spout leading from said secondary fiuxing vessel, and a trap dischargepipe leading from the bottom of the main fluxing vessel and having its upper end or leg terminating below the upper edge of said main fiuxing vessel, substantially as specified.

2. The combination with a fluxing vessel, of fluxing-rolls, a feed-table having rails for the sheets to rest upon extending at an angle to the direction of the movement of the sheets on the feed-table, and a feeder for pushing the sheets along said rails, substantially as specified.

3. The combination with hollow fiuxingrolls, of means for heating said rolls, a fluxing vessel containing oil or flux in which the lower rolls revolve, and provided with a trap water-discharge for automatically separating from the oil or flux in the fluxing vessel the water which collects from the wet sheets passing between the fluxing-rolls, the outer leg of the trap extending up to a less height than the level of immersion of the rolls in the flux to keep the water in the flux vessel out of contact with the rolls, substantially as specified.

4. The combination with hollow fluxingrolls, of means for heating said rolls, a fluxing vessel containing oil or flux in which the lower rolls revolve, and provided with a trap water-discharge for automatically separating from the oil or flux in the fiuxing vessel the water which collects from the wet sheets passing between the fiuxing-rolls, and a watercollecting vessel below the fluxing vessel, the outer leg of the trap extending up to a less height than the level of immersion of the rolls in the flux to keep the water in the flux vessel out of contact with the rolls, substantially as specified.

5. The combination of fiuxing-rolls with a fiuxing bath or vessel below the rolls, a feedtable and feeder, a tinning-pot and a curved chute for receiving the sheets horizontally from the fiuxing-rollsand delivering and defleeting them vertically into the tinning-pot, substantially as specified.

6. The combination of fluxing-rolls with a fluxing bath or vessel in which the lower rolls revolve, a feed-table and feeder, a tinningpot, a curved chute for delivering and deflecting the sheets from the fluxing-rollers into the tinning pot, and a supplemental narrow, open-ended flux-containing vessel projecting at its lower end into the molten tin in the tinning-pot, substantially as specified.

7. The combination of fluxing-rolls with a fluxing bath or vessel in which the lower rolls revolve, a feed-table and feeder, a tinningpot, a curved chute for delivering and deflect= ing the sheets from the fiuxing-rollers into the tinning-pot, a supplemental narrow, openended flux-containing vessel projecting at the lower end into the molten tin in the tinningpot, and an overflow discharge-spout at the lower end into the molten tin in the tinning- IO pot, and guide-bars for the sheets insaid supplemental fluxing vessel, substantially as specified.
