APPARATUS FOR MAKING SHEET METAL.
SPECIFICATION forming part of Letters Patent Nn 406,945, dated July I6, 1889. Application med Aprii, 1889. serian.. 306,206. (remodel.)
To all whomit may concern:
Be it known that we, EDWIN NORTON andl JOHN G. HoDGsoN, citizens of the United States, residing in Maywood, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Apparatus for Making Sheet Metal, of which thefollowing is a specification.
Our invention relates to improvements in- IO apparatus for making sheet metal, and more particularly to improvements upon the apparatus heretofore patented by us in Letters Patent No. 382,319, dated May 8, 1888.
The object of our present improvement is i 5 to provide means for governing the space between the revolving rolls by which the strealn of molten metal is converted into sheet metal,
so that the sheet metal produced maybe made of uniform thickness 'throilgllout'and not. be
zo subject to the variations due to the expansion or contraction of the metal rolls, the springing of the frame-work, or other causes. The means which We employ to accomplish this result consists in providing each of the metal rolls with apair of collars orperipheral faces which bear against like collars on the opposite roll, so`that the working-faces of the two rolls cannot crowd closer together when the rolls expand bythe heat. Between the 3o rolling faces or collars and the working-faces of the rolls we also provide peripheral grooves or recesses toinake room for excess of metal due to any variation in the rate at which the molten metal is poured between the rolls.
3 5 The working-faces of the rolls in our present improvement, as in our previous patent, No. 382,319, are made wider than the strip of sheet metal desired to be produced, so that any vari ation in the rate of pouring the molten 4o metal may be compensated for by variations in the width of the strip of sheet metal produced. The annular grooves between the working-faces and the rolling-faces of the rolls also give additional rogm or space to receive any excess of metal in case there should be any great variation in the rate of pouring.
Another feature of our improvement consists in combining with the chilling-rolls and pouring-nozzle a pair of finishing-rolls and a 5o guide chute or passage extending from the chilling-rolls to the finishing-rolls, so that the she'etor strip of metal produced maybe turned into a horizontal direction as it issues from the chilling-rolls. This second pair of rolls also serves to finish or further roll the sheet as it is produced while it is still ata comparatively high temperature.
In the accompauyingdrawings, which form a part of the specification, Figure l is a plan view of a device or apparatus embodying our 6o invention, and Fig. 2 is a central vertical section of the same on the line l 2 of Fig. l.
.In the drawings, A represents the frame of the machine. B B are the hollow chillingrolls, having the smooth working peripheral faces I), which revolve together, with a space between the rolls equal to the thickness of the sheet Vmetal tolle produced. D `is the pouring' bowl or vessel, having an opening d,
through which the stream of molten metal 7o V issues directly downward between the two hollow rolls B B and in a direction tangential to both. This pouring-bowl is furnished with a valve d for opening and closing the discharge-orifice (Z. The general construction of the hollow rolls, the pouring nozzle or bowl, the mechanism for revolving or driving the rolls, the means for causing the water to circulate through the hollow rolls, and other parts ofl the machine are or may be the same 8c as that shown and described in` our previous patent, before referred to; and as our present improvement does not particularly relate to these features we' do not deem it necessary to show or describe the same in detail, but would refer to our previous patent for a more complete description of such parts.
The hollow rolls B B are provided on each side of the working-faces b of the rolls with rolling faces or collars or stops b2, which roll 9o together and thus limit the extent to which the working-faces b may approach cach other and the size of the space or passage b between such working-faces of the rolls. Between the stop collars or faces b2 of the rolls 95 and the working-faces b we also provide each of the rolls with grooves b3, which grooves may receive any excess of metal that may issue from the pouring-nozzle.
C is a curved guidefor detlecting or de- Ioo livering the sheetfmetal strips f to the horisurface speed.
zontally-arranged rolls G G. The rolls G G may be revolved in any suitable manner; but they are preferably geared with the rollsB B, for-convenience in driving them .at Jthe same The rolls G G, which receive the sheet1netal strip in ahorizontal position, also serve, or may serve, to further roll oriinish the sheet. 'The curved guide C is especially serviceable for guiding or directing the end of the sheet-metall strip between the rolls G G when the operation begins. After the end of the strip, as indicated at s in the drawings, is started between the rolls G G it will naturally bend or curve by its own weight, and `the curved guide C is not at this part of the operation so necessary. The rolls B B, as well as the rolls G G, are also to be revolved at a surface speed equal to or greater than the velocity of the stream oi' molten met-al issuing from the pouring-vessel D. The curved guide() also serves to give a little slack between the chilling-rolls B and the,polishing rolls G, to compensate lfor any momentary 4diiterence of speed or slipping of the rolls.`
We claimf 1. `The combination'of two revolving chillin g-rolls IBv B with a pouring-vessel above and between them, said rolls B B having Workingfaces l) b and rollingfaces or collars b2b?, serving' as stops to regulate the space between the working-faces of the rolls, substantially as specified.
'- above and between them,
guide, substantially 2. The combination, with a pair of revolving chilling-rolls, of a pouring-nozzle ar 35 said rolls having working-faces and rolling-faces outranged above and between them,
sidev of the working-faces, and grooves or recesses between the rollin g-faces and the working-faces, substantially as specified.
3. The combination, ing chillin g-rolls, of a pouring-vessel arranged and a sec'ond'pair of rolls G G, substantially as specified.
' 4. The combination', with a pair of chillingrolls andpouring-vessel arranged above and between them, of a curved guide for deflectingA and chilling-rolls, of finishing-rolls, substanf ltially as specified. s
