COE, OF WATERBURY, CONNECTICUT, ASSIGNOR TO THE AMERICAN BRASS COMPANY, 0F `WATERLBURY, CONNECTICUT, A CORPORATION OF CONNECTICUT ADJ USTIN G MEANS FOR ROLLING-MILL ROLLS Application filed April 19,
justing means which will positively and accurately hold theroll in adjusted position.
It is also an object of the invention to provide a roll adjusting means which is very simple in construction and is easily operated.
With the above and other objects in view, the invention consists in certain novel features of construction7 combinations and arrangements of parts as will be more fully described, a vconstruction illustrating one form of the invention being shown in the ac. companying drawings. In these drawings,
Fig. l is an end elevation of the upper portion of the roll housing showing my invention as applied thereto.
Fig. 2 is a cross section substantially on line 2--2 of Fig. 1 on a somewhat larger scale, and
Fig. 3 is a front elevation of the upper part of the roll with my invention applied thereto, a'portion of the housing being broken away to more clearly show the construction.
The arrangement illustrated comprises the usual housings or frames 5 having the upright rectangular opening 6 forming guides for the bearings or supporting members 7 for the necks 8 of the rolls 9. Guide plates 10 retain these blocks or supporting members in the housings.
A transverse opening 11 is bored through the upper part of the housing, preferably so that it opens at its lower side through the top connecting portion 12 of the housing. This bored opening is preferably at substantially right angles to the axis of the rolls and horizontal. Mounted between the housing and the bearing or supporting member 7 is a pair of wedges 18 and 14. 'The lower .wedge member 13 is substantially rectangular-,1n cross section and is recessed into thev upper wall of the member 7 as shown at 15, and it has a lcross key 16 seated in a similar cross groove 17 in the top of the member 7. This wedge i is, therefore, permanently held in proper position on the member 7. Its upper wall 18 1928. Serial N0. 271,148.
is inclined as indicated in Fig. 1, and if preferred instead of this inclined wall running continuously the entire length of the wedge this wedge may be recessed as shown at 19 intermediate its ends to reduce the friction between this wedge and the upper wedge 14.
The upper wedge 14 is of general cylindrical form in cross section and is flattened at its lower side 20. This flat surface is inclined to the axis of the wedge at the same angle as the surface 13 of the lower wedge. The diameter of the wedge 14 is the same as that 0f the bore 11 so that the curved upper wall of the wedge has acontinuous and uniform bearingl in this bored opening. It will be apparent that as the wedge 14 is forced in-` wardly or to the left, as viewed in Fig. 1, the camming action of the inclined surfaces 13 and 20 `between the two wedges will force the roll supporting member 7 downwardly to adjust the relative positions of the rolls and determine the gauge of the stock rolled.
Means is provided for conveniently adjusting the wedge member 14 in or out. In the arrangement shown the wedge 14 is provided with a tapped opening leading from its outer end in which is threaded an adjusting screw 21 mounted in a suitable thrust bearing 22 mounted in the housing. Mounted on the outside of the housing is a bracket 23 and mounted on' the screw 21 is a bevel ear 24. j There is a bracket 23 in each housing on the front side wall thereof carrying a horizontally extending shaft 25 which has beveled pinion 26 meshing with the gears 24. For the purpose of ease 0f manufacture and in mounting, the shaft 25 may be made in sections connected by interlocking collars 27, and suitable hand wheels 28'are provided for operating the shaft 25 and through it the adjusting screws 21 to shift the wedge members 14 and adjust the upper roll 9 as will be lreadily understood. This construe tionprovides the same uniform and simultayneous operation for the two wedges 14 at the opposite ends of the roll'. If the clutch 27 lis disconnected the two wedges may be independently adjusted.
It will be apparent from the foregoin description that in this arrangement o the wedges there is an absolutely uniform bearing provided throughout the entire length of the upper wedge irrespective of the roll position in the housing. There is also alwaysl a uniform bearing between the two wedge members 13 and 14 as the member 14 may turn on itsv axis in its bearing in the housing. This, therefore, :makes a Very. effective adjusting means which is always uniform in operation, and the strain of the rolling operation is carried by the wedge members instead of the threads of the'adjusting screws as in the old form of adjustment.
Having thus set forth the nature of my invention, what I claim is:
1. In a rolling mill including a housing member and a roll supporting member, a pair of wedges between the said members, one of said wedges being substantially rectangular in cross section, cooperating means between said wedge and one of the members to retain the wedge in position, the other member being provided with a cylindrical guideway extending transverse the axis of the roll, the otherwedge being provided with a cylindrical wall to t said gu'ideway and a flat side to engage the other wedge, and a screw threaded in -said second wedge for shifting said second wedge and concentric with said cylindrical wall so that said wedge can turn in theguideway about the axis of the screw.
2. In a rolling mill including a housing member and a roll supporting member, a substantially cylindrical vwedge having a flat surface at one side inclined to the axis of the wedge, one of said members being provided with a cylindrical guideway to fit the curved wall of the wedgel and extending transverse the axis of the roll, means on the other member cooperating with said flat surface, and an adjusting screw connected with said wedge concentric with its lon itudinal axis so that said wedge can turn in t e guideway about the axis of the screw, said screw being adapted for longitudinally shifting the wedge to adjust the position of the roll.
3. Ina rolling mill, a housing provided with a transverse cylindrical opening forming a cylindrical guideway extending transverse the axis of the roll, a substantially cylindrical wedge mounted in said guideway having a flat surfaceon one side `inclined to the axis of the wedge and a longitudinal threaded openingconcentric with its longitudinal axis so that the wedge may turn in the guideway about the axis of a screw in said opening, a roll supporting member movable in the housing, a substantially rectangular wedge on said member having an inclined side wall engaging that of the first wedge, and an adjusting screw in said threaded opening for longitudinally shifting the first wedge 0 adjust the position of the supporting memer. i
4. In a rolling mill, an upright housing, a vertically movable roll supporting member in said housing, said housing being provided with a transverse cylindrical opening, a similarly shaped wedge mounted in said opening and having a flattened side wall inclined to the axis of the wedge, a similarly inclined wall on the supporting member cooperating with that on the wedge, and an adjusting screw connected to the wedge concentric with its longitudinal axis so that the wedge may turn in the opening about the axis of the screw, said screw being adapted for shifting the wedge. e
5. In a rolling mill, an upright housing, a
vertically movable roll supporting member4 in said housing, said housing being provided with a transverse cylindrical opening, a substantially cylindrical wedge mounted to slide in said o ening and having a fiattened side wall inehned to the axis of the wedge, a rectangular wedge mounted on the supporting member having an inclined wall cooperating with that of the firstwedge, said first wedge being provided with a tapped opening leading from one end thereof concentric with its longitudinal axis so that the wedge may turn in the cylindrical opening about the axis of a screw. in the tapped opening, and an adjusting screw threaded in said tapped openmg.
In testimony whereof I affix my signature.
