APPARATUS FOR TREATING AND TINNING PLATES.

SPECIFICATION forming part of Letters Patent No. 708,970, dated September 9, 1902.

Application filed July 10, 1901. Serial No. 67,778. (No model.)

[:0 all whom it may concern:

Be it known that I, J AMEs'R. PHILLIPS, of Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Apparatus for Treating and Tinning Plates, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming part of this'specification, in which- Figure 1 is a top plan view showing the left-hand end portion of a plant constructed in accordance with my invention. Fig. 2 is a similar viewshowing the right-hand end portion. Fig. 3 is a longitudinal section of Fig. 1, taken through the troughs; and Fig. 4 is a cross-section on the line IV IV of Fig. 1. Fig. 5 is a longitudinal section, on a larger scale, of a portion of the swilling trough, showing one of the swinging switches and lifting-cam.

My invention relates to the automatic delivery of sheets to tinning-pots, and is designed to provide improved apparatus which will automatically act upon a series of plates fed thereto and transfer them to different tinning-pots and also pass them through the tinning apparatus and branning apparatus and carry them to the assorting-room. The preliminary treating may consist in pickling and swilling or the swilling alone or simply in a wet delivery of the sheets, my apparatus being adapted for use in either way, though I have shown it as arranged for both picklingand swilling prior to feeding to the tinning-pots.

In the drawings, 2 represents a table upon which the plates are placed when taken from the annealing-stand by the operator. The plates are squared up on this table against side guides 3 and are then fed singly and successively through sets of rollers 4: 4 to a set of feed-rollers 5 5. The plates thence pass through guides 6 to feed-in rollers 7 and thence through guides 8 to a series of sets of feed-rollers 9, which rotate in the pickling liquid and feed the sheets successively through the trough 9. I also provide in this picklingtrough sets of brush-rollers 10, which are located between the rollers 9 and driven at a higher speed, preferably twice as great as the feed-rollers. These brush-rollers are provided with brushing-surfaces of any desired form and coact with the pickling liquid to remove the scale and impurities from the surfaces of the plate, thus greatly shortening the time required for pickling. At the end of the pickling-trough the sheets pass through feed-out rolls 11 and guides 12 to a set of transfer-rollers 13 and thence through feedin rollers 14 and guides 15 into the swillingtrough 16. This swilling-trough is provided with sets of feed-rollers 17, with intermediate guides 18, similar to those in the picklingtrough, the swilling-trough being of sufiicient length to allow a series of tinning and branning machines to be located at different points in its length. The swilling-trough is also preferably provided with brush -rollers 19, which brush the surfaces of the sheets similarly to the rollers 10 in the pickling-trough, but which need not be placed as closely together as those in the pickling-trough.

At suitable distances apart along and over the swilling trough I provide swinging switches 20, which are swung by lifting-cams 21 to raise them into inoperative position or lower them into position to receive a sheet as it is fed through the swilling apparatus. The cams for these swinging lifters or switches and all of the feed-rollers and brushing-rolls are driven from a common shaft 22, which extends alongside the pickling and swilling tank and is connected with the feed-rollers and brush-rolls by bevel-gears 23. The cams for the successive switches are so arranged or timed that they will be lowered successively to pick up the successive sheets passing through the swilling-trough, and in order that the operator may know to which tinning apparatus any particular sheet will be fed I provide at the table 2 an indicatorwheel 24, which is driven from the same set of connections as the shaft 22 and is provided with a series of numbered pins or pointers 25, corresponding to the number of the tinningpots. The gearing of this indicator-Wheel is so timed that when the number of any particular pot appears on the pin or spoke of the wheel above the table the sheet fed by the operator at that moment will be picked up by the switch of the pot having that number, and hence if any pot is out of order the number forsuch pot may be removed from the in dicator-wheel and the operator will then omit the feeding of the sheet for such number.

The system is intended to operate upon plates up to thirty-two inches in length and of any width from sixteen to twentyfour inches, and the speeds are so arranged in the formishown as to allow the travel of thirtythree inches for each sheet to allow clearance between the sheets. The time of passage of each plate from the original feed-rolls to each switch is accurately determined, and the lifting-cam for such switch is set on the shaft at such a point that it will lower the switch before the previous plate has completely cleared, so that when the next plate belonging to it reaches this point it will be engaged and lifted as soon as one-half the plate length has entered such switch and has engaged the set of feed-rollers 26 at the upper end of the lifter; Any plate not properly seized by its own switch will not be engaged by any of the switches, but will be fed through the entire swilling trough and deposited at its end, where such plates can be gathered up when the operations upon sheets of that size have been finished.

In feeding different sizes of plates the only change in the apparatus will be to increase or decrease the speed for different widths of plate, the speed being increased for plates of less Width and decreased for wider plates. This can be easily arranged by using a step form of pulley having the fastest speed for, say, plates sixteen inches wide and different speeds for each two-inch difference in widths up to plates twentyfour inches wide.

The plate having been seized by the appropriate switch and deflected into the bite of the feed-rolls26 therefor is fed through guides 27 and rollers 28 to and upon an endless-belt carrier 29. This carrier consists of sprocketchains carrying angle-bar pushers 30. The carrier travels slower than the feed-trough, but at about twice the speed of the tinningmachine. Stops are used at the rear side of the endless carrier to stop the plate at the proper point, according to its size, so that it can be fed into the center of the tinning-machine, these stops being adjustable for such purpose. The pushers 30 are preferably set at about forty-two inches apart, this being twice the average width of the plates, and the sprocket-chains are timed so that sufficient time is allowed for the plate to settle between the pushers and on the stationary carry-bars between the sprocket-chains. The plate is then fed over plate 31 and into the first set of feed-rolls 32, leading to the tinning-machine and rotating at the same speed as those of the machines, and as the sheet passes through such feed-rolls it is acted upon by brush-rolls 33, which have the same surface speed as the sprocket-chains and about twice the speed of the tinning-machine proper. The plate is fed through the tin-pot 34 in the usual manner, and as it emerges from the upper rolls 35 thereof it is seized by a mechanical catcher 36, which may be of any well known type, and is thereby fed into a branning-machine 37. From the branning-machine the plates pass through a duster 38, and thence to a feed-table 39, which carries the plates singly to the assorting-room, this carrier extending alongside the different dusters.

In the operation of the apparatus the sheets are fed one by one to the pickling-trough as the pointers on the indicator-wheel are successively brought above the table. As they pass through the pickling-trough they are subjected to the combined action of the pickling fluid and the brush-rolls,and thus quickly and efficiently cleaned. They then pass into the swilling-trough, and as each plate reaches its switch it is engaged thereby and taken to the tinning-pot corresponding to the number on the indicator-wheel in position at the time the sheet was fed. The sheets thus pass to the different tinning-pots in succession and are automatically fed through these pots and through the branners and dusters to the common feed-table, by which they are delivered to the assorting-room.

The advantages of my invention result from the automatic feeding of the sheets to the different tinning-pot-s, the doing away with the large amount of manual labor, and increasing the output, while improving the quality of the sheets and decreasing the quantity of wastes and practically eliminating menders.

The feed-rollers may be made of any suitable acid-proof material. The switches, the indicator, and the feeding devices, as well as the particular form of the tinning-pots, &c., may be varied widely without departing from my invention as defined in the claims. The apparatus maybe used without the picklingtrough, in which case the feed-table and indicator would be arranged at the front end of the wet feeding-trough.
