wrrER FOR coa'rme MACHINES;
Application filed January 12,1925. Serial No.1,814.
This invention relates to an apparatus for coating sheets and plates with moltenmetal,
and more particularly to the wipers or brushes used to remove the surplus molten metal from the feed out rolls of the apparatus. An object of the invention is to provide an'improved form of wiper or brush h at will bear with uniform pressure against the rolls throughout its length. Another in object of the invention is to provide a novel form of wiper which will wear evenly and be in perfect contact with the roll during the entire service of said wiper.
A further object is to construct a novel unitary form of wiper which is compact and does not double under. the roll.
A still further object of the invention is to construct a wiper device wherein the wiper may be removed and replaced quickly and does not require additional clamping means to hold the wiper in place.
ll-leretofore wipers used to clean the feed out rolls in metal coating machines were preferably made of laminated sheets of asbestos or the like, being reinforced by alternate layers of wire clamped together by suitable means. These brushes have worn unevenly and double under the roll when pressure is applied, thus making imperfect contact and not only making that part of the wiper useless but also producing waster sheets due to the surplus coating material being carried over by the rolls and redeposited on the sheets when the rolls are insur'iiciently wiped. Furthermore, this type of wiper is diflic-ult to remove when once in use as the fastenings become clogged with the coating material, stick fast and are found difficult to loosen. The present invention comprises generally a tinning or. galvanizing pot in which the tin or spelter or other coating material is maintained in a molten condition. The pot has a series of feed out rolls mounted therein. Wiper bars are depended from the pot and extends beneath the rolls to support the wipers. The wipers are of rope formation weaved from stands of asbestos, or similar heat resisting material, preferably reinforcedwith wire metallic threads. The
wipers are seated in a semi-circular or concave longitudinal groove formed in the wiperbars and are held in place by pressure against the rolls. In the embodiment of my invention, I prefer the use of asbestos in the three sets of feed out rolls (17), (18) and construction of the wipers, however, in so far as the broad aspectsof my invention are concerned, it is to be understood that any $11111."
able fire resisting material may be used. The novel features will be more fully understood from the following description and claims, taken with the drawing.
Fig. 1 is a fragmentary vertical section of a tin pot embodying the invention.
Fig. 2 is a fragmentary side elevation of the wiper device.
Fig. 3 is a side elevation of the wiper. cut away to illustrate its core.
Fig. 4: is a cross section of the wiper taken on lineIVIV of Fig. 3. Referring now to the drawings, (10) indicates a tinning pot of old and approved design. The pot is separated transversely by a Vertical wall (11) into compartments (12) and 13). The lower edge of this wall (11) terminates above the bottom of the pot and defines the width of a narrow passage (14) through which the plates or sheets pass from compartments (12) to the compartment (13). Tin, spelter or other coatin materials are maintained in a molten condition in the pot and on the surface of the coating material in compartment (13) is maintained a body:
of oil. The forward end of the plates being tinned are. directed into the compartment 13) from compartment (12) between guide plates (15) and (16),.which direct the forward end of the plate upwardly into the bite. of the lower set of feed out rolls (17) of- (19) mounted in the upper end of compartment Each of the rolls in the aforementioned sets is provided with a wiper (20) composed of strands of asbestos having ametallic center and in rope formation. Preferably the wiper comprises a core of twisted strands of asbestos contained within sheaths of braided asbestos fabric and having the strands reinforced with a plurality of metallic wire threads. The wiper is seated in a semicircular longitudinal groove (21) formed in the upper face of the bar 22) and extends the length of the roll. The bars (22) are supported at each end on hangers (23) which are depended from a beam (25) supported on the side walls of the pot (10). The hangers (23) are provided at the upper ends with adjustable collars, (24:), and interposed betweenthe latter and the supporting beaiii I may-be easily renioved merely by r'eleasing It Will readily be seen that Witli'the above described construction the w ipers will have a substantially constant. tension and uniform bearing against ther IIGSPGKZtiYGTIOHS regardless of the Wear and that this tension 'imay be readilyz adjusted byvadjusting the collars (249.
