To all whom :it may concern:
Be itknown that I, BERTHOLD "GOLDSMITH, aresident of Lisbon, in the county of Columbiana and State .of Ohio, have invented a new and useful Improvement in Apparatus for Coat-ing Sheet Metal, of which the following is a specification.
This invention relates to apparatus for coat ng roll, sheet and plate metal with a coating of metal or alloy, and more particularly to apparatus for coating such metal on one surface only.
The object of the invention is to provide for this ,purpose an apparatus of simple con,- struction, whereby roll, sheet .or plate metal can be rapidly and thoroughly coated with a substantially uniform layer of the coating metal or alloy, and whereby the coating metal is prevented from getting onto the edges and the upper surface of the roll, sheet prevented from being wasted. The invention comprises the construction and arrangement "of apparatus hereinafter described and claimed. i In the accompanying drawings, Figure 1 1s a plan view of the apparatus; Fig. 2 is a slde elevation of the same; Fig. 3 is a vertical longitudinal section through the coating tank or post taken on the line -33, 1 and showing the same on an enlarged scale; Fig. -l 18 a vertical"transverse section of the same taken on the line 4-4, Fig. 1; and Fig. 5 is a cross section through one of the fluxdis tributing and absorbing pads taken on the line-55, Fig. 1.
In the drawings, 1 illustrates a suitable frameof any adaptable construction or material upon which the operating parts are mounted. Mounted in one end of the table or frame l is a suitable spool or drum 2 upon which -is placed a coil or roll of the metal to -becoated, when roll metal is used.
3 represents a fluxing pan or tank, preferablya lead pan, for containing the fluxing material such as chlorid of zinc. in frame -1 to revolve in .pan 3 is fiuxing r01 1 4. This fluxi-ng roll is preferably covered with cotton or other suitable soft material for depositmg .flux on the under side of the roll, sheet, or plate. The sheet or plate 6 is held .-in contact with said roll by means of two idler rolls-5, one on each side of the pan 3 and underneath which the sheet or plate passes. By this arrangement the -'uI-1der-surface of the sheet or plate is thoroughly Mounted fluxed. The sheet or plate then passes over one or more distributing and absorbing pads 7 which preferably are constructed of Wood or metal covered with a fibrous substance, such as cotton cloth. These pads distribute the flux evenly over the under surface of the sheet or plate and also absorb any surplus into a suitable stove or furnace 10 in which a fire of any character may be maintained, in order to maintain the coating metal or alloy in a suitable fluid condition.
Mounted transversely in the pot 'or tank 9 so as to dip down into the same, is a paddle wheel 11 provided with a suitable number of longitudinal-vanes 12 for splashing the coating metal or alloy up against the under surface of the sheet or plate from the pot or tank. The paddle wheel 11 is positively rotated in the -direction of the arrow 12, that .is in a direction contrary to the direction of travel of 'the metal being coated.
"To properly guide the sheet or ,plate over the tank an also to .prevent the coating .anetal or alloy from being splashed on to the edges or on to the upper surface thereof, I provide suitable guides at the'sides of the ,pot or tank for receivin the edges of the sheet or ,plate. These guldes 13 are of special-construction being of a flattened tubular or elliptical shape, as shown in .the drawings, with longitudinal slits 14 on their in her sides into which the edges of the sheet or ,plate are entered. The peculiar construction of these guides prevents any of the coating metal or alloy from being splashed onto the *edges'or onto the upper surface of the sheet or :plate, and any coatingrnetal which is splashed up against these guides mostly drops back into the pot. In order'to adapt the apparatus to coat roll, sheet or-plate metal of varying Widths the guides 13 are adjustable transversely of the apparatus, or toward and from each other. This is-preferably effected by supporting the guides from angle plates 15 projecting inwardly from the sides of the frame or 0t and pro vided with transverse slots 1'6 or-receiving of-a gas or oil burner, or by setting the same flux which may have .been deposited thereon I bolts 17 which" connect the guides to said plates. This/permits of the ready adjustment of the/guides toward and from each other as will be readily understood' Over the rear edge of the tank are arranged one or more stripping rods 19 in position to have the sheet or plate drag over the same, and which serve to-distribute the coatin metal or alloy over the sheet or plate and a so remove a considerable ortion of the sur lus coating metal or al 0 which remove portion drops back into the pot 9.
' The sheet onplate then passes over one or b/inore rotary wipers or brushes 20, two such 1 rushes being shown. These are in the form of rolls and are covered by a suitable yielding wiping material, preferably tow, although the coverin may be of any other fibrous material. The sheet or plate is held down against thc wi ing brushes by being passed beneath theid er rolls 21, three such idler rolls being shown. The brushes 20 are positively rotated in the direction of the arrow 22, that is in a direction contrary to the direction of travel of the sheet or plate and serve to wipe off surplus coatin material and to finish the lower coated sur ace of the sheet or plate. In conjunction with each of said wiping rolls, I rovide a scraper and guard in the form of a curved plate 24 attached to the frame or table and having a scraping edge 25, serving to scrape 01? from the wiping roll 20 any coating material which may adhere thereto, and also serving as a guard to prevent such coatin material from being thrown up against the ower surface of the sheet or plate. Any suitable mechanism may be used for drawing the roll, sheet or plate metal through the apparatus described. As illustrated, this is effected by means of a spool or drum 27 rotatably mounted in suitable bearings on the table or frame 1 and upon which the roll, sheet or plate metal is or could be wound. The driving mechanism for the various rotating rolls and the s 001 or drum may be arranged in any desire or preferred way. The drawings show one arrangement of such mechanism. Power is applied-to the fast and loose pulleys 29 on the spindle or shaft 30 of the winding spool or drum 27. From this spool or drum rotary movement is communicated to the Wiping rolls or brushes 20 and to the paddle Wheel 11, by sprocket chains 31 working on sprocket wheels 32 secured to the spindles or shafts of the spool or" drum 27, the wi ing rolls or brushes20 and paddle whee 11. The driving mechanism is arranged to rotate the various parts in the direction indicated by the arrows andvat the necessary speeds.
, The apparatus described is of simple constfuction and so arranged as to quickly, thoroughly, and uniformly coat roll, sheet.
or plate metal. Surplus coating material is scraped and wiped ofi fro'm the roll, sheet or late metal so as to give a practically umorm coating and the edgw and top surface of the sheet or plate metal are kept reasonably clean from the coating metal.
The operation of the ap' aratus described will be readily understoo from the foregoing descriptlom What I claim is, 1. Apparatus for coating-roll, sheet or plate metal comprising a pot or tank for the coating material, a rotarypaddle wheel therein, means for drawing the sheet or plate over the said tank and paddle wheel, and guides arran ed at the sides of the tank-to receive the e gesof the sheet or plate and being so formed as to prevent the coating metal from being s lashed onto the edges and upper surface 0 the sheet or plate.
