sraoretohmonror in part of ietjirs Patent No, 721,69,dated February 24, 1903. Application filed $eptember 1901. Serial 110. 76.9134. (m lit a) Belit known that I, J ULIAN KENNED Pittsburg, in the .county of -Alleghenyfa d State of Pennsylvania, have invented new and useful Rolling-Mill- Feed-Talole, of which the following is a full,flclear, and exact-de-' scription, reference being bad to the accompanying drawings, forming part of this specification, in whi'ch- Figure 1 is a side elevation showinga threehigh rolling-mill provided with my improved tables. Fig. 2 is a vertical cross-,sectionon' a larger scale,and'Fig.3 is a partial top plan View. V
My invention relates to rolling-mill feedtables, and-particularly to those employed for three-high mills, though certain" features of my invention may be applied to driving therolls of any feed-table;
The object of the invention is to simplify and improve themeans for raising and lowering and guiding the vertically-movableta' ble and also to provide improvedspu'rf-gear ing driving mechanism fortherollers offthe feed-table.
In the drawings, 2, 3 and 4: represent the. rolls of a three-high mil1,,'mounted' in suit able honsings5 5. ,On each side of the mill are provided vertically-movablefeed-tables 6 6, which are similar-toeaeh other and are raised and lowered simultaneously to each other in parallel lines c, Each table isfgiven its parallel vertical movement through pivotal links 7 7 connecting the side framesof the table to lever-' arms 8 8, projectingfrom-parallelshafts-9 9. These two shafts 9 extend beneathbothifeed-ff tables, so that the tables are actuated simultaneously, and to one of each pair of links7 1 is pivoted a radius-link 10, the other end of which is pivoted at a fixed point 11 on the bracket 12. A parallel movement is thus imparted to both feed-tablesin the raising and lowering thereof, and to rock the shaft 9 I provide them with downwardly-extendinglevers 13, which are connectedby link 14, one of the levers 13 being connected by links 15 to the plunger 16 of a large motive cylinder 17. This single-acting cylinder 17 is connected with an accumulator 17 which exerts a constant pressure upon the plunger, and thus normally holds the tables and metal provided with across-head 18, having con necting-rods 19, which extend throughguides 20 to asimilar'cross-head 21, "secured to the ram 22.0w smaller hydraulic cylinder 23.
in Figs. 2 and 3 and may be applied, to any table havihgpositively-driven rollers. I have shown each table as havingeightrollers,which are arranged in pairs alternating with single -rollers. The rollers 24 and 25 are provided at one end with small pinions 26, which engagean intermediate pinion 27 upon a small transverse shaft extending through the hol- -low sleeve or bolt 28andcarrying at its other end a large toothed wheel29. This toothed wheel 29 engages toothed wheels 30, secured 1 to the proje'ctin g shafts of theadjacent single rollers on each side of the pair at this side of thereonfin elevated position, acting as a liquid counterbalance therefor. The plunger 16 is the table Power'is appliedtoldrive the roll- -ers'by;any suitable connections, such as a swinging rotary shaft or'belting, which may -be connected to the shaft of any of the rollers. I have shown the shaft between the central pair of rollers on each table as having a confnectionj 3 1,"through which power may be applied.- This peculiar arrangement of the gearable Wear of the rollers near the mill for theconsequent lowering of the axes of these rollers. The table is therefore longer lived than in the case of the beveled-gearing tables ordinarily used and gives economy in the amount of power used for driving it.
Many variations may be made in the form of the mill and the tables and the actuating mechanism without departing from my invention.
I claim- 1. A feed-table having link-and-lever connections with parallel rock-shafts extending parallel with the table, a link arranged to give parallel up-and-down movement to the table, and connections for rocking the shafts; substantially as described. 7
2. A rolling-mill having vertically-movable tables on each side thereof, said tables having link-and-lever connections with a pair of rock-shafts extending longitudinally beneath both tables, link connections for giving parallel movements to the tables, and mechanism for rocking the shafts; substantially as described.
3. A vertically-movable feed'tab1e,a powercylinder connected thereto, connections for exerting a constant pressure on the cylinder to counterbalance and hold the table in elevated position, and a second cylinder arranged to act in opposition to the first and lower the table; substantially as described.
4. A rolling-mill feed-table having a transverse shaft geared directly to an adjacent roller at one end and to a non-adjacent roller side a gear-wheel intermeshing on either side with a gear-Wheel mounted on a roller-shaft, the first-named gear-wheel being mounted on a transverse shaft having at the other end gear connections with other rollers of the table; substantially as described.
In testimony whereof I have hereunto set my hand.
