APPARATUS FOR THE MANUFACTURE OF TIN-PLATE.

. by declare the following to be a full, clear,

apparatus by which the and exact description thereof.

Our invention relates to apparatus for making tin or coated plates and has reference more especially to the apparatus employed in the treatment of the plates preparatory to the tinning or coating.

The object of our invention is to provide operation may be carried on continuously, the plates being fed in at one end of the apparatus in succession plates through the first pickling and removed from the op osite end, having been properly treated and ready for white or finish annealing preparatory to the tinning or coating operation.

In the drawings Figure l is a diagrammatic view in elevation of our improved apparatus; Fig. 2 is an enlarged partly in section of the rolls for loosening the scale, and the mechanism for feeding the bath; Fig. 3 1s a plan view ofthe same; Fig. 4 is a sec tion on the line 4-4, Fi 2; Fig. 5 is an enlarged sectional view 1 the pickling vats showing the conveyer chains for holding the plates in carrying them through the pickling vats; Fig. 6 is'a section on the line 6--6 Fig. Figs. 7, 8 and 9 are detail views of the conveyer chain; Fig. 10 is an enlarged detail of the drying and heating apparatus; Fig. 11 is' a plan view thereofand Fig. 12 is an enlarged detail View of the heating rolls.

In the drawings the numeral 2 designates suitable housings for the cold rolls 3 employed for loosening; the scale from the sheets. The-, 'upper of these rolls isgiadjustable by means of the ordinary adjusting screws so that the heavy pressure may 7 brought tobe'ar upon the sheet beingrolled and this heavy pressure will act to'break up the scaly surface of the sheet and loosen the scale preparator to the passage of the sheet through the pic lingbath. Theserolls are driven from any suitable source of power, and connected up to the combination roll coupling and sprocket isthesprocket wheel- '4 which is connected up by the chain 5 to the sprocket wheel can the shaft7.

on the shaft 15.

detail view hold the plate shaft 7 has the sprocket wheel 8 which is connected up by the chain 9 to the sprocket wheel 10 on the shaft 11, the sprocket wheel 12 which is connected up by the chain 13 with the sprocket wheel 14 This shaft 15 carries the belt pulleys 16 arranged at suitable intervals apart and conveyer belts 17 connect said pulleys 16 up with the pulleys 18 on the shaft 19. The shaft 15 is journaled in suitable hearings in the housings or frame 20.

A lever 21 is connected to the rock-shaft 22 mounted in the fiqame and secured to said rock-shaft are the arms 23. These arms 23 are adapted to engage the rocker arms Patented May 3, 1910.

The shaft 11 has 2st on the shaft 25. These rocker arms 24 work in the spaces between the belts 17 and are employed for the purpose of directing the wasters or im erfect sheets up into the rolls 26 to be delivered onto the platform 27. Deflectors 28 are emplo ed for directing the sheet up into the roll 26 and a deflector 29 above said rolls acts to direct the sheet onto the platform 27.

The drums 30 on the shaft 11 act in connection with the small rolls 31 to feed the plate so that when a defective plate is to be directed up between the rolls 26 said plate will be positively fed to properly accomplish this result.

A pickling vat 32 is formed of wo0d, con

crete or metal which will resist the action of the acid and the sheets are carried down to said vat by means of the conveyer chains 33 and 34. These chains pass around the sprocket wheels and at the opposite end pass around the sprocket wheels 36 which may be connected up to any suitablesource of ower to drive said chains at the same rate 0 speed.

In order to take up space within the vat and reduce the amount of pickling acid, we employ the filler, 32. Secured to the bottom of said filler are the strips or guides32? with which the upper chain engages while the bottom chain is drawn up snugly against the top chain. The filler 32 thus acts as a guide for the chains and the upper chain moves mcontact with said guide while the -at one end of said vat lower'chain is drawn up ,in such a way as to securely between the chains in the manner this construction the acid is given full opportunity to attack-the-plate. These chains 34 are made of metaLwhich will resist the action of-thea'cid andthe links 37 of said hereinafter set --forth. By

chains are connected by the cross-bars 38. Contact-lugs 39 are carried by the bars 38, said lugs being preferably knife-edged, as indicated, so as to present as small a contact point as possible to engage the surface of the plates. The contact-lugs 39 of the one chain are arranged at right angles to the contact-lug on the other chain, and said lugs on said chain are arranged the same distance apart so as to coincide with each other when brought around in position to engage the plates, as indicated in Fig. 2. These chains 33 and 34 pass'down into the pickling vat 32 and carry the plates supported thereby through the pickhng acid.

Just ahead of the pickling vat' 32 is a second pickling vat 40 similar in constrpction to the one ust described and chains 41 and 42 are mounted on sprocket wheels 43 and 44. In the case 'of the chains 41 and 42,- however, the contact-lugs 45 and 46 are arranged the reverse of the contact-lugs 39 of the chains 33 and 34 for the purpose fully hereinafter set forth.

49 for cleaning the plates and said cold water vat has the conveyers 50 for feeding the plates through said vat.

. throughthe ho The plates pass from the cold water vat -49 to the hot'water vat 51, which is used for washing the plates as well as heating the same preparatory to drying; A suitable conveyer chain 52 is likewise employed for carrying the plates through said'hot water vat. Just in front of the hot water vat 51 is the belt conveyer 53 which is mounted on the rolls 54. r

Mounted in'the frame 55 are the rolls 56 which are closely adjusted for squeezin the water from the plates and in advance of said rolls are the heating rolls 57. Three sets of these heating rolls are illustrated although any" desired number may be employed. These rolls are connected u and driven from one -of the rolls 56. hese heating rolls, as illustrated in Fig. 12, are hollow rolls with a 1perforated pipe 58 passing low journals '59, said pipe bein connected up with a suitable gas pipe 60 provided with the mixer 61'. This is the construction where gas is employed to heat the rolls but we do not wish to limit ourselves to any particular manner of-heatingfthe same. Guards 63 are secured'to the .11... m 1 59 by means of the set screw 63,

said guards being employed to protect'the Intermediate the pickling vats 32 and 40, however, may be interposed the brushes 47 for loosening the plates are held outer ends of the journals from the heat of the rolls; These guards may be formed of asbestos or any vother suitable material.

Beyond the heating rolls is the belt conveyer 64 which receives the sheets from the heating rolls, said belt being mounted on the rolls 65. Intermediate rolls 66 driven by the chain 67 from the sprocket wheel 68 connected up by the chains saw the sprocket wheel 7 0 on the lower roll 71 of the cold rolls which are mounted in thehousings 7 2; In the use of our improved apparatus the plates are fed singly to the cold rolls 3 and the scale is loosened by the passage through said rolls. The operator stands in a convenient position where he can view the plate as it leaves the rolls and if for any reason said plate should be defective so that it is not desired to feed it to the pickling vat the operator, by moving the lever 21, throws the rocker arms 23up 1n position to engage the forward end of the plate and lift it up in such position as to cause it-to-strike the deflector 28 and be directed up between the rolls 26. The plate, on passing from the rolls 26, is directed by the *d eflector 28 onto the table 27 to be removed therefrom.- If,

on the other hand, the plate contains no de-, feet as it leaves the rolls 3, said plate is carried along on the belts 17 and is delivered to the chains 33 and 34. The chains 33 and 34 I are so arranged as to speed, travel, etc., that the contact lugs on one chain will contact with the contact lu'gs' on the oppositechain so that when the plate is fed to said chains, said chains will engage opposite faces of the plates with the lugs and said plate will be securely held and carried the acid of thepickling vat 32. The knife edges of the contact lugs bein the'only parts of said lugs in contact with the plate a l the surfaces of the plate are subjected to the action of the acid with the exception of such parts of the lates as are covered by the contact-edges o the contact-lugs and in this manner the plates are delivered and carried one in succession through the picklin vat 32. As the plates emerge from the pic ling wt 32 they are fed by the rolls 48 'to the brushes 47 where such brushes are employed positively through and the scale is removed by'said, brushes.

The plate is then engaged by the chains 41 and'42, and owing to the reversal of the position of the contact lugs on said chains 41 and42 from that on the chains '33 and 34 the at new points of contact and the old points of contact are exposed so that as the plate is fed through the vat-40 the acid has an opportunity to reach that POP-1 tion of the plates not acted on'by the acid of the vat 32.. The plates continue in succession through the vat 40 and as they emerge therefrom they pass down into the water of the vat 49 where they are washed and they then pass into the hot' water vat 51where the plates are further washed and heated. In passing from the hot water vat 51" the plates are fed to the rolls 56 which act to squeeze the water from the plates, and they then pass between the-heated rolls. These rolls are heatedto about one thousand degrees Fahrenheit and act to thoroughly dry the plates and heat the same. The plates are then carried bythe conveyer belts 64 to the cold rolls.

By our improved apparatus. the plates are fed continuously and successively, thereby saving a great deal of time and labor. The sheets are held and carried positively through the pickling vats in such a manner that all parts are exposed to the action of the acid and there is nohandling of the plates from the time they enter the cold rolls 3 until they pass from the cold rolls 71. The drying of the plates is accomplished by the heated rolls 57 and thisdrying does away with the black annealing which is necessary in .the process ordinarily practiced in the treatment of the plate. This black annealing required a number or hours and caused great delay in the treatment of the plates and involved extra handling of the plates and consequent labor and expense attending the same, not to mention the cost of the annealing boxes themselves. By theterm knife edges, as used in the claims, we wish to convey the idea of a contact lug with edges of such a character which will have a small point of contact and we do not wish to limit ourselves to a sharp knife-like edge in that sense of the word.
