Specification of Letters Patent. ,Patentedotj 21, 1.9119,
vApplicationined.January'31, 1918. Serial 110.214,628.
To all lwhom t l:any concern.: l
-Be it known that I, ALLAN F. JAeoBsoN,
' a citizen of the United States, and resident ing, and the 1 devised will progresses. l
As another object, the invention contem-l vmaticall ,of the borough' of- Richmond, county of Richmond, city and State of New York,
have invented certain new and useful Improvements in Treating Metals, of which the following is a specification.
The object of this invention is to provide a means for automatically treating metals, and more particularly for annealing metals by drawing or rolling and cleaning them after they have been annealed. As I -refer to annealing during or directly after rolling, it maybe understood that the metal that I refer to may generally-be considered brass, bronze, copper, or other metals which harden in the process of rolling.
I have discovered that much time is consumed in rolling a strip of metal for annealing or in placing metal sheets or plates in the ovens for annealingpurposes, and that because of the diiliculty of evenly distributing the heat, sheets, and particularly rolls are sometimes destroyed during the annealing process. 4
My object then is to provide a means for annealing and cleaning metals during` actual process of rolling, or directly thereafter, .and without the necessity of removing the metal from the rolling mill, or of coiling it, or otherwise preparmgit for annealprocess or method which'I h ve e set forth as the speci'ficatlonl plates the provision of a meansy for autoregulating the temperature to l .whicli -t e strip is heated and l'naintaining the strip heated during the cleaning process. A still further object of the invention relating the temperature of the strip byl the f f sides in the provision of a means for reguerature ofthe cleaning liquid.
tem
' efollowing is whatiI consider a good means. of carrymg outmy invention, and
` used in -myA met the accompanying drawings should be referred to for a qcox'nl'ilete understanding ofA4 the specification which"` follows.
In the drawings-thegure shows in side elevation and llaarly in section the device i ySimilar refe'renv numeralsu indicate parts in all of the figures where they appear.
i' or the rollers 1 and 2, thereof, are a p In describing my method, 1 sin am de;
scribe the method that I employ to accomplish the desired purpose, It will be noted,
however, that'for the most part, the drawingsshow this device as a diagram.` lThe reason for thisis quite obvious. yIt is possible to vary the arrangement or change the by means to be later described through thev devices employed in my process.
In line with the rollers 3 and 4, and. placed a distance therefrom, isanother pair of rollers 5 and 6, and between the rollers 3 and '5, I- arrange a continuous conveyer belt 7 preferably of asbestos or other re' proof material. A4 second conveyer 8 passes around! therollers 4 'and 6, 'and this belt should also be of asbestos or other fire-proof material; AAdjacent to the rollers 3 and 4, is a tank 9 provided with a lurality of rollers 10, 11, 12, 13 and 14,*all o which may be arranged within the tank and it willbe noted that while the conveyer belts 7 and 8- and the strip of metal M pass into the tank over the roller 10, and closely adjacent [to each other,fthe rollers 11, 12 and 13 are placed apart, so that during its passage through ythe tank. 9,`the conveyer belts are .drawn awayv from the metal M exposing.
this metal to the-contents ofthe l Within this tank 9,'andprobably adjacent to one side thereof; I arrange a metallic plate 15, i
and 'I' connect this lplate witha lead or electri'cal conductor 16 which will be again referred to. The tank 9 contains mercury in constant contact: with the plate 15, and with the/metal M'passing. through. tle tank.v ,Placed awagv from the tank 9, are other tanks v17 and 1 and these two tanks 17 vand 418 may be :formed as shown in the drawing as'one unit,
with -a proper dividing wall to keepA their v `contents separated, or two entirely separate'tanks may be employed.
Rollers' 19, 20, 21, 22 and 23 within the tank 17,'and rollers 24, 25, 26, 27 and 28 within the tank l8'serve the same purpose as 4.do the rollers 10, 11, 12, 13 and 14 in tank 9, receiving and conveying through the @tank and through the contents thereof, the
asbestos conveyer belts and the metal strip arranged between them, separating the strip serve the same purpose as do the other small) rollers described as' contained in or adjacent to the tanks 9, 17 and 18.
This tank 29 is also provided with a metallic plate 35 to be later referred to.
Within the tank 17 I arrange al thermopile 37. or other thermostatic device electrically connected by wires 38 with a relay 39. This relay operates a motor 40 which in turn, controls or operatesthe arm 41, of a current regulator 42.
Now I will describe the method-of operation as employing the devices previously referred to, and it is desired4 to roll the copper to such a degree that the proper reduction thickness cannot be accomplished by-a single rolling operation, or let'us consider that it isv desired that the finished metallic'sheet or strip should be annealed. The metallic strip M will be received from the rollers 1 and 2, and` will pass between the conveyer` belts 7 and 8 and between the rollers 3 and'4. The rollers 3 and 4 of the belts 7 and 8 will convey the metal through the tank 9, into and through thetanks 17 and 18, and into the tank 29. When the end of the metal strip is received in the tank 29, a suitable electric current is caused to pass through the leads or supply lines 43 and 3 6, one of these lines or leads being connected ,directly tothe plate 35 in the tank 29, and the other lead passing into the current regulator 42. It'will be noted that the motor 40 1s directly connected to the line lead 43 and through the relay 39 is connected to the line lead 36.
Current will pass through the current regulator 42 lnto the conductor 16 tothe tank 15, and from thence into the metallic plate or strlp` being treated, to theytank 29, plate 35, and back to the line.
The thermostatic device 37l will control the degree to whichl the metallic -plate or strip M may be heated, and if there be a tendency to overheat, the thermostatic device* 37 through the relay and motor 40 will introduce into the line cutting down the current applied tothe plate or strip M.
If the normal or allowable temperature is. 1.
not reached, a reverse operation will result, and resistance will be cut out by the movements of the arm 41. and the current regulator.
The actual annealing will occur in the space between the tanks 9 and 17 and when the metal passes through the tank 17, the acid bath will -remove any foreign matter or oxidization that may result from the heating of the metal; the water'in the tank 18 removing the acid before the metallic strip enters the tank 29.
The electric current continues to pass through the metallic strip until it reaches the tank 29, will l warm the strip after its passage from the tank 18, but it is not de sired that the separation of the tanks 18 and 29 should be sufficiently great to allow the metal to become heated to a degree sufiicient to cause oxidization.
The content of the tanks 9 and 29 will probably be mercury, although it is possible that I may utilize other metallic salts' in solution or any other material that may be retained in a liquidor semi-liquid state,
and which will'serlve as an elicient electrical conductor between the plates and the metallic strip passing through the tank. It is possible that I may desire to chan the position of the tanks; I may place t e tank 29 approximately in the position now occupied by the tank 17 moving the tanks 17 and 18 to the relative position of the present tanks 18 and 29, and in this way,
there would be no passage of current through the metallic strip under` treatment and whilefsaid strip is passing through the acid or waterrontaining tanks. The length of the conveyor belts and the distance between the tanks may be changed at will, and other modifications may be made within the scope of the appended claims, without departing from the principle or sacrificing the advantages of the invention; although I prefer to retain the principle as heretofore set forth, wherein a continuous treatment 1s made possible and wherein the resistance of the metal treated is dependent upon to coperate with the current supply to raise the temperature to an effective'degree. In certain classes of work, the conveyor belts may be omitted, and obviously, handuregulation of the current may be substituted for the ,said strip under the heating action of an electric current, passing said strip through a cleaning liquid while still under the action of the electric current and automatically regulating the temperature to which the strlp is hea a. 1
2. The method of annealing metal which consists in advancing said metal in a continuous stripbringing successive portions of said strip under the heating actionof an electric current, passing said strip through a cleaning liquid while still under the action of the electric current and automatically regulating the temperature to which the strip is heated by the temperature of the said cleaning liquid.
3. The method of annealing metal which consists in passing the same in a continuous strip between' and in close contact with a pair of moving heat insulating members,
applying an electric ,current to the portion` thereof between said members and passingy the strip through a cleaning solution 'at a point between those at which the current 1s y supplied.
lstrips comprising a JI-an., 1918.'
4. An apparatus for annealing metal pair of endlessheat insulating bends havlg adjacent reaches adapted to receive the metal strip therebel,tween to advance the latter, means for elecmore tanks located under thegeneral nor- `mal plane of said adjacent reaches, and
means in said tanks adapted to depress the 'said bends and strip thereintoand to space them apart. y
