ROLLING-MILL.
Specification of Letters Patent.
Patented Mar. 1, 1921.
Application filed May 10, 1916. Serial No. 96,597.
To all whom it may concern Be it known that I, ALFRED I. (311001;, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented Rolling-Hills, of which the following is a specification.
My invention relates to 3-high rolling mills of the type having a fixed center line or middle roll, and has for one of its objects the provision of novel means for carrying or supporting the top roll of such a mill.
It is further desired to provide a novel system of counter weights with the necessary connecting members, for supporting the top roll of a 3-high mill of the type noted;-the arrangement being such that the struts employed are guided or movable within, the body of the housing of the mill, while the bearings supported by said struts include projections extending into vertical recesses in said housing whereby they are retained in place and vertically guided.
The invention also contemplates the provision of a novel arrangement of wedges for adjusting and lockingin place the bearin structures for the middle roll of the mill, and contemplates such an arrangement of parts and disposition of material as will make the mill substantial as to structure and satisfactory as to operation.
These objects and other advantageous ends I secure as hereinafter set forth, reference being had to the accompanying drawings, in which,
Figure 1 is an end elevation, partly in section, of a 3-high rollingmill constructed according to my invention;
Fig. 2 is a side elevation, partly in vertical section. further illustrating the mill shown in Fig. 1;
Fig. 8 is a plan of the counter-weights and their associated levers;
Fig. 4 is a fragmentary vertical section on a larger scale taken in the plane of one pair of bearing-supporting struts;
Fig. 5 is a horizontal section on the line 5-5, Fig. 4; and
Fig. 6 is a perspective view of one of the wedges employed between the pillow blocks associated with the middle roll.
In the above drawings 1 represents a pair of substantially parallel tracks or guides stud 21.
upon which are mounted the two housings 2 of the mill, and each of these is provided witlrthe customary retaining cap 3 held in position by bolts 4. In the bottom of the vertically extending guideway of each housmg is mounted a pillow block 5 supported upon a threaded shaft 6 which passes through a nut 7 carried in a suitable recess in the central lower part of the housing structure. The lower end of each of the shafts 6 has fixed to it a gear 8 engaging a long faced pinion 9 supported upon a shaft 10 carried in a vertical bearing 11 fixed to the outer face of the housing structure to which it is attached. Any suitable means, such as a handle 12, may be employed for turning said shaft 10 at will in order to actuate the corresponding shafts 6 and raise or lower the pillow block 5.
Each of the pillow blocks 5 carries a hearing 13 in which rests one end of the lower roll 14. Above said pillow blocks the vertical guideway of each of the housings is laterally extended for the reception of a pair of pillow blocks 15 and 16, of which the lower is solidly-supported upon projecting ledges of said housings and carries a bearing 17 which serves to support the middle roll 19 so that its axis is at all times fixed relatively to the remainder of the frame.
For the purpose of adjusting the distance between each pair of the pillow blocks 15 and 16, I insert a pair of wedges 20 between them on either side of the neck of the roll and form each of the wedges with an overhung head through which passes a threaded Each of these studs has a nut whereby its wedge may be forced inwardly between the pillow blocks 15 and 16 so as to move them to and froand retain them at any given distance apart.
The upper pillow block 16 with its bearing 18 is adjustably forced toward the pillow block 15 and held in any given position, by means of a second pair of wedges 22 inserted between it and a suitable overhung part of the housing structure. These wedges like the others, have turned over ends engaging studs 23 provided with nuts, whereby said wedges may be forced inwardly when desired. The pillow block 15 is held in the housing by a pair of plates 24 held to the outer face of said pillow block by nuts 25.
Similarly each of the upper pillow blocks is held in place by plates 26 engaging its outer face and held in position by nuts on bolts 27.
The housings above the fixed-center middle roll have their adjacent faces vertically slotted for the reception of the projecting ends 28 of a lower bearing 29 carrying the top roll 30. Each of said bearings is carried upon a pair of rods 31 constituting struts which extend through elongated guideways or channels in each of the.
housings and at their lower ends respectively engage the short arms 32 of levers vfulcrumed to links 33 hung to the,1ower part of the housing structure. The long arms 34 of said levers extend. toward and past each other as shown in Fig. 3, and have attached to their extremities counter weights 35 which are suspended approximately midwe between the two housings 2.
he upper roll is also engaged by upper bearings 36 held in place by pillow blocks 37 guided in the respective housings and carrying blocks 38 engaged by the lower ends of ter weights, whose mass is such as to over-. balance said roll and the structures which screws 39- threaded through suitable nuts 40 in the caps 3. These bolts have hexago-j nal heads whereby they may be screwed up or down at will or they may be" rovided with any other desired means to acilitate their adjustment,
It is particularly to the above described arrangt ment of parts, the position of the upper roll may be accurately adjusted to give a definite. con'stant thrust against the upper bearings since it is yieldingly forced against them by the counit carries. In other words, the weight of this rollis carried solely by the struts 31 and it is at all times pressed up toward the bearings 36 by a constant force.
- Moreover by the arrangement of parts be noted that with i been adjusted by in said bearings, top and bottom rolls and their bearings means for adjusting the bottom roll, an an I equalizing compression system for the top roll and its bearin s whereby they may be adjusted bodily wit out disturbing their relation. v
2. The combination in a 3-high rolling mill of housings; two sets of pillow blocks mounted in said housings; wedges operative between said pillow blocks of each set; bearings in the pillow blocks; a normally fixedcenter-line middle roll mounted in said bearings; a top roll; a bottom roll; and means for maintaining said latter rolls in operative relation to the middle roll.
3. The combination in a 3-high rolling mill of housings; two sets of pillow blocks mounted in said housings; wedges operative between said pillow blocks of each set; bearings in the pillow blocks; a normally fixed-center-line middle roll mounted in said bearings; a top roll; a bottom roll; means for maintaining said latter rolls in operative relation to the'middle roll; with wedges operative on the upper pillow block to retain it in any position to-which it has said first wedges.
