INVENTQR n O Q MM mcc JOSEPH E. FAWELL, PITTSBURGH, PENNSYLVANIA, ASSIGNOR TO MACKINTOSH- HEMPHILL .& COMPANY, OF PITTSBURGH, I ENNSYLVANIA, A COBPORATIQN 0F PENNSYLVANIA.

To all 'whom it may concern:

Be it known that I, JOSEPH E. FAWELL residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, a citizen of the United States, have invented or discovered certain new and useful Improvements in Rolling-Mills, of which improvements the following is a specification.

The invention described herein relates to certain improvements in manipulating mechanism for rolling mills, and has for its object the operation of such mechanismby and simultaneous with the shitting of the rolls. The invention is hereinafter more fully described and claimed.

In the accompanying drawings forming a part of this specification, Figure 1 is a top plan view of a rolling mill embodying the improvements claimed herein; Fig. 2 is a sectional elevation of the same; Figs. o and 4: are views similar to Figs. 1 and 2 showing the improvements in connection with another form of mill proper; Figs. 5 and 6 are transverse sections on planes indicated by the lines V-V and VI-VL Fig. 1.

The improvements claimed herein are shown and described in connection with the type of mills in which the reducing rolls are nonreversible, the reversing of the article being effected by changing the positions of the rolls, but the invention is not limited to use in connection with the types shown.

1n Figs. 1 and 2 the mill which is of the Fawell type consists of two pairs of rolls and 2 so mounted in movable housings 3, that when one pair of rolls are in operative relation to the feed tables. the upper roll of the other pair will be below a plane tangential to the rollers of the feed table. Suitable mechanism (not shown) is employed for so rotating the rolls that one pairwill move the article in one direction and the other `pair feed the article in the opposite direction.

In Figs. 3 and 4 is shown the liamberton type of mill in which a single pair of reducing rolls are mounted in housings 6. rotatable through an arc of 180 degrees. and are driven by suitable nonreversing mechanism (not'shown). Stationary feedl tables 7 and 8 provided with reversible feed rollers are arranged on opposite sides of the mill. Buggies 9 are arranged below the feed tables having their supporting wheels Specification of Letters Patent.

mounted on rails l0 parallel or substantially parallel with the axes of the feed rollers. These buggies are provided with standards 11 projecting up between adjacent rollers and having guide bars 12 secured thereto. These guide bars extend along the tables at rigid angles to the axes of the rollers and consequently substantially parallel, the lines of movement of articles being reduced by the rolls. As the guidebars are shifted by the buggies any article or articles lying between the bars will be moved in directions parallel with the axes of the rolls into alinement with a pass in the rolls.

The buggies are connected by rods 13 to arms 14 of bell cranks 15, which have their other arms connected by a rod 16 to a rocker arm 17 of the shaft 18. In the construction shown in Figs. 1, 2 and 5, the shaft 18 is provided with a second rocker arm 19 which is connectedby a pitman 2O to the housing carrying the two pairs of reducing rolls .so thatby rotating the shaft 18, the housing is shifted to bring the other pair of rolls to operative position and the iide bars are also shifted to bring the article into alinement with the desired pass. The rotation of the shaft 18 is preferably effected by means of fluid pressure cylinders 21 having their piston rods connected to a rocker arm 22 on the shaft.

As in the Lamberton mill shown in Figs. 3 and 4, the housing must he rotated through an arc of 180 degrees, a rack bar 22L adapted to be reciprocated by fluid pressure cylinders 23 engages a pinion 24 on the shaft 25, having keyed thereon a pinion 26 intermeshing with a circular line of teeth on the housing of the rolls. The shaft also carries a beveled pinion 27 intermeshing with a correspondingly shaped pinion 28 on shaft 29 which is provided with rocker arms 30 connected by pitmen 31 to the buggies carrying the guide bars of the feed tion for such purpose is shown in Fig. 6,

and consists of fingers 32 arran ed in guides on the standards 1l, and aving their lower-ends connected to one arm of bellcranks 34 pivotally mounted on the standards or buggies, the other arms of the bellcranks being Atied to a side-bar 35 of the feed table by links 36, or otherwise anchored, as against movement with the buggies. As the buggies are moved to the right in Fig. 6, the pivotal points of the bell-cranks Will be moved, and the free arms of the latter Will raise the fingers, which engaging a corner of the billet or other article will turn it axially.

While the mechanisms shown and described herein are Well adapted for shifting the roll housings the guide bars and the tui ning devices, other means will readily suggest themselves to the skilled engineer, and hence within the scope of the claims, the invention is not limited to the specific constructions shown.

I claim herein as my invention:

1. In a rolling mill, the combination of reducing rolls, a feed table, means for turning articles lying on the table, and means for Muzi...

simultaneously shifting thc rolls nud turning means. i

2. In u rolling mill, the combination of reducing rolls, a t'ccd table, guide bars mo\- able across the table, means for turning an article lying on the table, and means for simultaneously shifting the rolls, guide bars and turning means.

3. In a rolling mill, the combination of a pair of rolls, means for moving said pair of rolls in the arc of a circle, a feed table stationary as against vertical movement, and means operative by the roll moving means for moving an article across the front of the reducing rolls.

4. In a rolling mill, the combination of a rotatable housing, two pairs of nonreversing rolls mounted in turning the housing, and means operative by the housing turning means for moving an article laterally across the front of thc rolls.

In testimony where-of, I have hereunto set my hand.
