Specification of Letters Patent.
Patented Dec. 26, 1916.
Application filed June 30, 1916. Serial No. 106,909.
To all whom it may concern:
Be it known that we, DAVID R. JENKINS and RAYMOND MOELHANEY, both citizens of the United States, and residents of Morgantown, in the county of Monongalia and State of est Virginia, have invented certain new and useful Improvements in Tilting Mechanisms, of which the following is a specification.
Our invention relates to apparatus for eliminating list from the edges of tin and terne plates and similar coated metal plates or sheets. The coating on the sheets or plates as they emerge from the tinning or coating pots is still molten, and as the sheets or plates are lifted lengthwise vertically the excess coating being molten will fiow toward the lower edges of the sheets or plates and will collect at the lower margins so as to form a somewhat thickened coating or list edge at the lower marginal end of the sheet or plate.
One object of our invention is to provide a tilting mechanism of simple construction having novel means for handling the sheets and plates as they emerge from the pot of coating metal and for tilting the coated sheets and plates so as to cause any excess molten coating metal to be uniformly distributed over the surfaces of the tilted sheets or plates, and to thereby eliminate and prevent the formation of list edges on the margins of the coated. sheets or plates.
Other objects of the invention are to provide a tilting mechanism having. novel means whereby the sheets and plates are supported at a plurality of points on the marginal edges thereof; whereby contact by the tilting mechanism with the surfaces of the coated materials is avoided and made unnecessary; and whereby scratching of the surfaces of the coated sheets and plates is prevented and overcome.
A further object of our invention is the provision of a tilting device having the novel constructions, combinations, and arrangements of parts shown in the accompanying drawings, to be more fully described hereinon the arms are shown in horizontal position for the sake of clearness. sectional end elevation of the apparatus of hugs. 1 and 2 with the tilting arms shown in plate receiving position A and plate removlng position B.
In the accompanying drawings the numeral 2 designates a shaft which is arranged to extend horizontally and is mounted at its ends in bearings 3 and 1. The bearings 3 and 4 are secured in fixed position adjacent to the exit end of a tinning pot or vessel containlng the tin or other molten coating metal.
One end of the shaft 2 is provided with a flange or disk 5 having a set screw 6 in its boss 5 to adjustably fasten the disk on the shaft. The periphery of the disk 5 has relatively angular flattened portions 7 and 8 thereon at each of diametrically opposite polnts, and the portions 7 and 8 are arranged to engage with the free end of a flat spring member 9 which is conveniently riveted or otherwise fastened to the vertical leg of the shaft bearing 3, the spring 9 acting to yieldingly hold the tilting mechanism 1n tilted or plate receiving and plate removing positions.
Adjacent to the ends of the horizontal shaft 2 are proclivous guide bars 10 or 11 rigidly fastened by one end to the shaft 2 and having upwardly and outwardly extending bent portions 10*, 11 arranged to project above the upper surface of the rock shaft 2. Preferably the upper edge of the bent portionsl0 11 will be beveled as shown so as to provide a sharp edge to contact with a point on the edge of a sheet or plate 15 supported on the tilting mechanism instead of having a surface contact therewith. Also rigidly secured on the tilting shaft 2 are proclivous, transversely extending arms 12 and 13. The end portions 12*, 12*, and 13 13 of the arms are bent to project upwardly and outwardly and have a hook 14 at the outer end of each upwardly inclined portion 12, 13 The hooks 14 are beveled to form knife edges 14 and the upper edges of the bent portions 12 13 of the transverse arms also are beveled so that the guide bars and the arms have a point contact instead of a surface contact with the edges of sheets or plates supported thereon.
One end of the horizontal shaft 3 is provided with a crank 16 by which the tilting mechanism is rocked in the bearings 3 and Fig. 3 1s a surfaces 7 and 8 on the flange 5, to yield-' 4, the spring 9 engaging with the flattened ingly hold the tilting mechanism in tilted positions and to maintain a sheet or plate 15 supported thereon in tilted position while any excess molten coating metal is being redistributed over the surfaces of the coated sheet or plate.
By reference to the drawings it will be apparent that the sheet or plate 15 1s supported on. its marginal edges by a po1nt contact with the beveled edges 10 11 of the two guide bars, and beveled edges 12*, 13, on each end of the two transverse arms 12, 13, and that a surface contact by the tilting mechanism with the sheet or plate is avoided and the possibility of scratching or otherwise marring the surfaces of the coated sheet or plate is thereby prevented and overcome.
In the operation of our improved tilting mechanism, the arms 12, 13, will be tilted by a workman into the plate receiving position shown at A in Fig. 3. A sheet or plate 15 is then discharged from the exit side of the tinning pot or other vessel containing the molten coating metal and as discharged the sheet or plate 15 will be deposited upon the tilted arms 12, 13, of the tilting mechanism, in the position shown' at A in Fig. 3. The end of the plate last emerging from the tinning or coating pot, or list edge will engage with the hooks 14 on the lower ends of the arms 12, 13, and as the plate is received upon the supporting arms 12, 12, 13, 13, of the tilting mechanism, the beveled edges of the guiding bars 10 and 11 will operate to center the plate 15 on the tilting mechanism. A workman will then rock or tilt the shaft 2 by means of the crank 16 as soon as a sheet or plate 15 is deposited thereon, and the plate will thereby be tilted or inclined into the position B shown in Fig. 3. so as to raise the level of the list edge considerably above that of the opposite edge of the plate. As any excess molten coating on.the surfaces of the plate will be located at or adjacent to the list edge of the plate, tilting the list edge upwardly will cause the still molten coating ,metal to flow toward the opposite edge of the plate, and in flowing downwardly will be redistributed uniformly over the surfaces of the plate so that the formation of list on what would otherwise be the list edge of the plate will be avoided and overcome. When turned into the tilted platereceiving position shown at A in Fig. 3 the spring 9 on the bearing 3 'will engage with the flattened portion 8 and when turned in the opposite tilted position shown at B in Fig. 3 the spring 9 engages with the flattened portion 7 on the periphery of the disk 5, and will yieldingly hold the tilting mechanism and plate supported thereon in such tilted position while the coating metal is redistributing itself is in readiness to be delivered upon the tilting mechanism, the molten metal will have solidified upon the tilted plate then on the tilting device so that it can be removed without further liability of the formation of list on the edges of the plate from its position shown at B.
The above described operations are repeated with the successive plates as i the plates are discharged from the tinning pot upon the tilting mechanism, and by tilting the plates with our improved tilting device to raise the list edge or edge of the plate last emerging from the tinning pot above the opposite edge of such plate, the formation of list on the plate is prevented and overcome, and the production of scrap necessary in trimming list edge from the plates is overcome and avoided.
The advantages of our invention will be readily understood and appreciated by those skilled in the art.
Modifications in the construction and arrang'ements of the parts forming our improved tilting mechanism may be made without departing from our invention as defined in the appended claims.
