EDGAR G. PORTER AND JOHN I. JONES, OF ELWOOD, INDIANA, ASSIGrNORS TO AMERICAN SHEET AND TIN PLATE COMPANY, OF PITTSBURG, PENNSYLVANIA, A CORPORATION OF NEW JERSEY.
COATING APPARATUS.
Specification of Letters Patent.
Patented Dec. 3, 1907.
Application filed July 26. 1906. Serial No. 327.795.
To all whom it may concern:
Be it known that we, EDGAR G. PORTER and JOHN 1. Jonas, both of Elwood, Madison county, Indiana, have invented a new and useful Coating A paratus, of which the following is a full, cl ear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a vertical cross section of a tinning pot provided with our improved scra ers; Fig. 2 is a perspective view of one of t e scraper knives; Fig. 3 is an enlarged vertical cross section; and Fig. 4 is a plan view partly broken away showin the arrangement of the tinning rolls and znives.
'Our invention relates to the tinning or coating of metal sheets with another metal, and is designed to provide an improved device for regulating the thickness of the coating. It is also designed to provide means whereby the sheets may be tinned more rapidly than formerly, thus increasing the output of the tinning machine.
In the drawin s, 2 represents a tinning pot having the usua' tinning rolls 3, 3 and 4, 4. The level of the molten tin is preferably at about the level of the dotted line a, a, while the level of the oil is preferably at about the line b, b. The rollers 3, 3 and 4, 4 may be mounted in the'usual bearings in the frame 5 of the tinning machine which is hung in thepot.
In order to regulate the amount of tin left on the plate, and prevent the excess from passing around the upper rolls 4 and redepgjiting upon the late, we provide scraper 'ves which pre erably contact with the rising sheet between the two sets of rolls 3, 3 and 4, 4.
In the form shown each knife 6 consists of a blade having a comparatively thin curved edge portion which is preferably accurately ground so as to give an even continuoussmooth edge to bear against the surface of the coated plate. This knife blade may be made separate from or integral with stem portions 7 which rest upon pivoted brackets 8 loosely mounted upon shafts 9. The shafts 9, 9 are mounted outside of the rolls 3, 3 and in the frame of the tinning machine, and the brackets 8 may be either secured to the shaft so as to swing thereon, or the shaft may be locked and the brackets S allowed to swing upon it. The brackets are provided with slots through which pass bolts 10 for holding the knife stems, and these stems may be accurately adjusted by set screws 11 passing through the brackets and engaging suitable screw-threaded holes in the lugs 12 of the knife stems.
In the use of the apparatus, the scraper knives are preferably adjusted so that their ground edges are in parallelism and touch each other when no plate is passing. I/Ve have shown them as resting upon the lower rolls 3, 3 which prevent their dropping down below the normal position. When the sheet rises from the rolls 3, 3, its upper edge passes between the knives and rocks them slightly apart as it passes upwardly. Both faces of the sheet are therefore subject to a scraping action from those knives which bear lightly against them under the action of gravity. When no sheet is passing the knives drop back and the normal position is shown.
The advantages of our invention result from the increased speed with which the machine may be operated, since the surplus metal is removed before the sheets reach the upper rolls. The rolls may therefore be turned at a higher speed than formerly. The metal is also evenly distributed over the surface of the sheets as the knives tend to prevent the thickening of the coating on parts of the sheet.
The form and arrangement of the scraper knives as well as their material maybe varied. The knives may be placed in another location relative to the rolls, although we prefer to place them between the two sets which roll in the oil, and many other variations may be made without departing from our invention.
o claim 1. A coating machine having a pair of scrapers arranged to contact with opposite surfaces of the sheet as it rises from the coating bath, said scrapers consisting of pivotal metal blades having comparatively thin edge portions normally resting in contact with each other; substantially as described.
2. A coating machine having a pair of scrapers arranged to contact with opposite surfaces of the sheet as it rises from the coating bath, said scrapers consisting of pivotally supported thin-edged, metal blades normally resting in contact with each other and arranged to be separated by the sheet and to bear against the sheet by gravity alone; substantially as described.
3. A coating machine having a pair of scrapers arranged to contact With opposite surfaces of the sheet as it rises from the coating bath, said scrapers consisting of pivoted scrapers arranged to contact with oppositev surfaces of the sheet as it rises from the coat-- ing bath, said scrapers consisting of pivoted blades normally supported in substantially horizontal position, with upturned, com paratively thin, scraping edges, substantially as described.
In testimony whereof We have hereunto H. H. BAKER, TrIoMAs OBRIEN.
