Application November 18, 1935, lSerial No. 50,463 4 Claims. (Cl. 80-56) the cover is in use are iinished to secure `a tight This invention relates to rolling mills, one of the objects being to protect the screwdowns of such mills against the abrasive dirt which is incidental to rolling operations. Other objects may be inferred from the following disclosure of a specific example of the invention.
Referring to the accompanying drawings which illustrate this example: mill'igure 1 shows a part of the side of a rolling Figure 2 is a section from the line II-II in 'Figure 1.
Figure 3 is an enlargement from Figure 2.
Figure 4 is the same as Figure 3 but shows a different operating phase.
Figure 5 is an enlargement from Figure 3.
'I'he rolling mill illustrated by these drawings includesi'the combination-of a housing I providing a window'2, a roll-neck bearing 3 riding in this Window, a screwdown I projecting downy wardly from the top of this window and with its lower end arranged in connectionwith the bearing 3, and a series of mutually telescoping rings 5 closing the screwdown 4 from its lower end to the top of the window 2;. The uppermost one of the rings 5 is fixed to the top of the window and all of the rings are conical and progressively decrease in diameter downwardly from this uppermost one of the same.
This'series of rings constitutes a cover for the screwdown of the rolling mill. It may, of course, be used as a cover for screws incorporated by any large heavy machine.
As a means for fastening the uppermost one of the rings to the top of the window, the drawings illustrate a ange 6 that is fixed to the top edge of this ring and which may be bolted to the bottom of the mill top about the screwdown. A further feature is the use of heavy wire stiiening rings 'l which encircle the bottom edge por-v tions loi.' the rings 5, these portions being curled upwardly about the rings to maintain proper association of these elements. Also, the lower edge portion of the lowermost one of the rings 5 is provided with an upturned flange 8 having openings 9, and hooks I0 depend from the ange 6. When the series of rings is fully telescoped these hooks I0 may be inserted in the openings 9 so as to keep the cover out of the way during mill repairs or alterations.
It is to be particularly noted that each of the rings 5 is sufficiently narrow to permit the screwdown 4 to be raised sufficiently to permit the usual mill repairs or, alterations. As ismentioned above, the hooks I0 may be utilized to keep the cover out of the way, if desired.
Preferably, the rings 5 are made-out of sheet steel and their surfaces that interengage when ameter i'lt.
Although a specific example of the present invention has been disclosed in accordance with the patent statutes, it is not intended that the scope of the invention be limited exactly to this example, J except as defined by the following claims.
I claim:
1. A rolling mill including the combination of a housing providing a. window, a roll-neck bearing riding in said window, a screwdown projecting downwardly from the top of said window and with its lower 'endl arranged in connection with said bearing, and a series of mutually telescoping rings enclosing said screwdown from its lower end to thetop of said window, the uppermost Lone of said rings' being fixed to the top of said window and all of said rings being conical and progressively decreasing in diameter downwardly from said uppermost one of the same.
2. A cover for rolling mill screwdowns and the like, said cover including a series of conical telescopingrings which progressively decrease in didownwardly from the uppermost ring of said series so that no one can separate downwardly from another, and means for fastening said uppermost ring to the bottom'of a mill top about a screwdown.
3. A cover for rolling mill screwdowns and the like, said cover including a series of conical telescoping rings which progressively decrease in diameter downwardly from the uppermost ring of said series so that no one can separate downwardly from another, means for fastening said uppermost ring to the bottom of a mill top about a screwdown, stiiening ring members associated with the bottom edges of said rings and means for releasably fastening the lowermost ring of said series to said bottom of said mill top when said series of rings is fully telescoped.
4. A cover for rolling mill screwdowns and the like, said cover including a series of conical telescoping rings which progressively decrease in diameter downwardly from the uppermost ring of said series so that no one can separate downwardly from another, means for fastening said uppermost ring to the bottom of a mill top about a screwdown, stiffening ring members associated with the bottom edges of said rings and means for releasably fastening the lowermost ring of said series to said bottom of said mill top when said series of rings is fully telescoped, said rings being individually sufliciently narrow to permit said screwdown to be raised suieiently to permit usual mill repairs or alterations.
