'i'j STATES man MILL.
Application filed October 8, 1920. Serial No. 415,515.
To all whom it may concern:
Be it known that I, AUcUs'r SUNDH, a citizen of the. United States, and a resident of Hastings-upon-Hudson, county of Westchester, and State of New York, have invented certain new and useful Improvements in Mills, of which the following is a specification.
My invention relates to an improved machine for treating metal strips, for example, after the same have been annealed, whereby the strips may be cleaned and pre ared for further rolling operations if so a minimum amountof labor.
The machine is also designed to eliminate the more or less expensive method now practised, of treating metal strips wherein the coils after being annealed must be unwound or loosened manually and pickled, after which they are taken out of the pickle and a water tank to be washed and then taken out of the water tank and on a roll. This method is not only slow and expensive but also injures the strip, particularly when the strips are soft.
In the present instance I have provided an apparatus wherein the strips may be passed through a pickling unit and a washlng unit, the strips after passin from the washin unit being rolled or coi ed upon a collapsible winding block. After the strips are wound upon the winding block they may be transferred to a loose, rotatable, storage drum, the strips being taken from this storage drum if desired and rollin mill after which they may be again woun u By this construction a continuous picking and rollin operation is possible, one set of strips being pickled while anolther set is passing through the rolling mil.
It will be apparent, therefore, that the passage of the strips from the annealing furnace through the pickling system and the mill will be very ra id as compared with d involve only a minimum amount of labor.
It will be apparent also that inasmuch as the strips pass through the picklingunit in strip form as distinguished from being deposlted therein in a co'il,'the strip will be much cleaner than otherwise.
the accompanying drawings,-
Fig. 1 shows my improved apparatus in sectional elevation;
desired, with 1 placed 7 'tank, the strip at this time preferab passed through a- 2 is a plan view of the same; Fig. 3 is an enlarged, part sectional, plan view of the washing unit and one of the winding units;
Fig. 4 is a section taken on the line fr-4 of Fig. 3;
Fig. 5 shows a splicing'unit which may be employed in connection with my apparatus; an
Fig. 6 shows on an enlarged scale splice performed by the splicin unit of Fig. 5.
Referring now to the rawings in detail, designates a sup ort for receiving metal coils which are to be treated, thecoils being supported upon mandrels 2 which rest in slots 3 provided in the support 1. The strips, one of which has been shown assing through the'machine, are desi ate 4 and are led from the coil upon t e support 1 ich the stri pickle 7 and around a roller 10, again traversing the pickle and passing under a roller 11, and is then led upwardly over a roller 12 adjacent the top of the ickling y travehng in a vertical direction. The strip is then led downwardly into a washing tank 13 under rollers 14: and 15 therein and upwardly between scrubbing brushes 16 and 17 over a roller 18 and to and around a block or rotatable drum 19 which will be described in detail hereinafter.
The pickling tank 8 is provided at one end with arms 20 and at the other end with arms 21, the arms 20 carrying the rollers 6 and 10 already referred to while the arms 21 carry the rollers 9 and 11. The arms are preferably, though not necessarily, pivotally supported on shafts 22 connected with levers 23 and 2-1 so that the arms as a whole if desired maybe lifted bodily out of the pickle in the tank 8 carrying with them the strip, if a strip is being passed through the pickle at that time. This apparatus is pro vided so that if for any reason it be desired to shut the machine down it will be unnecessary to leave the strip in the pickle. The str1p in passing from the roller 11 to the roller 12, both of which have already been referred to, travels in a vertical direction, as already noted and is engaged by a wiper element 25 carried by pivoted arms 25' adapted to cause the wiper 25 to swing against the strip to wipe the pickle therefrom, the removal of the pickle from the strip being facilitated by the vertical travel of the strip at this time. The brushes l6 and 17 which scrub the strip, that is to say remove the dirt and scale therefrom which has been loosened in the pickling operation, are shown in detail in Fig. 3 from which it will be seen that they are mounted for rotation on shafts 2G and 27 extending transversely of the machine, these shafts being hollow and perforated. Each brush is divided into sections (see Fig. 1) each section containing the bristles of the brush so that water projected from the shafts 26 and '27 through the openings 28 therein maybe distributed throughout the bristles of the brushes by centrifugal force and be discharged upon the strips. This is a much more satisfactory arrangement than having the water applied to the brushes from the outside. The brushes are driven by a motor 29, this motor being belted to the shaft 26 and which shaft is connected by a pair of gears 30 and 31 to the shaft 27 to cause the brushes to rotate in opposite directions. Water is supplied to the shafts 26 and 27 by a pipe connection 32 which in turn is connected to a main water pipe 33.
As it may be desired to roll two or more strips into the one coil, I have provided means at the rear end of the machine, that is to say adjacent the supporting element 1 whereby the ends of the strips may be spliced together. This apparatus is shown, for example, in Fig. 5 the splice being shown on an enlarged scale in Fig. 6. From Fig. 5 it will be seen that a strip 4 which we will assume has passed through the machine and the rear end of which is at this time at the rear end of the machine, 'as a whole, may be spliced to the next strip designated 34 by means of a splicing device 35 which comprises an anvil 36 and a punch 37 which may be manipulated by foot power if desired. This splicing device is capable of striking up ortions 38 and 39 in the two strips which it is desired to splice in the manner shown in Fig. 6 after which a metal member 40 may be forced under the loops of metal so formed so as to effectually hold the two strips spliced together.
As heretofore noted the strip after passing over the roller 18 after having been pickled and washed, is rolled upon a drum 'or block shown in detail in Figs. 3 and 4 and designated 19 as a whole. This block comprises a rotatable, sectional shell 41, the endsof two adjacent sections overlapping as shown in Fig. 4 at 42 to form a slot in the shell whereby the end of a strip may be passed to the interior of'the shell. Within the drum or shell 41are provided'piv; oted sections 43 pivoted at 44 and connected at their other ends by toggles 45 to a longitudinally, slidable rod 46, the latter being supported in a core 47 with which the block or drum is provided and which core is secured to a shaft 48 having a bearing at 49 in the frame of the machine. The shaft 48 and therefore the winding mechanism 19, is driven from the motor 29 belted to a pulley 51 carried on the end of the shaft. 1f, now, the end of a strip be inserted in the slot 42 of the shell 41 and the rod 46 be forced inwardly, the toggles 45 will be actuated to force the members 43 outwardly to clamp the end of the strip between them and the interior of the shell sections 41. Inasmuch as the members 43 at this time are rotating due to their constant connection to the shaft 48, as soon as the strip is clamped the shell 41 will be rotated also to coil the strip upon the same. After the strip iscoiled upon the shell, the sections 43 may be collapsed and the shell 41 collapsed to ermit the coil of strip tobe transferred bo ily to a store e drum 52 which is freely rotatable upon tie shaft 48 and in line with the element 19. A new strip may then be fed to the element 19 and the operation 'ust described repeated. If, however, at this time it should be desired to operate upon the coil of strip now mounted upon the drum 52, the end of the strip may be led or passed between the rolls 53 of a rolling mill to be reduced and thereafter passed around a drum or block 54 which ma be of any desired construction, for examp e similar to the winding drum or block just described. The passage of the strip through the rolling mill may be simultaneous with the winding of a newly treated strip upon the winding. unit 19 if desired inasmuch as the drum 19 and the drum'52 are rotatable independently of each other. The winding of the strip upon the drum 54 completes the operation.
The mill rolls 53 and the drum 54 may be driven by the same motor if desired and as here shown, the drums19 is driven from the same motor as are driven the brushes 16 and 17 of the washing and scrubbing mechanism.
From the foregoing it will be seen that a strip after having been pickled and washed may be passed through a rolling mill to be further reduced and wound upon a receiving drum while at the same time another strip may be passing through the pickling and washing operation.
While I have described a specific embodiment of my invention it is to be understood that the details of construction may changed by those skilled in the art within the purview of this invention.
