Patented March 80, 1909.
Application filed October 9, 1907. Serial No. 396,593.
To all whom it may concern:
Be it known that 1, JOHN W. Fominn, a citizen of the United States of America, and resident of \Vheeling, county of Ohio, and State of West Virginia, have invented certain new and useful Improvements in Autoinatic Traveling Tilt'lables, of which the following is a specification.
This invention relates to new and useful improvements in tilt-tables, and more particularly to a traveling tilt-table; and it has for its object to provide a device for rollingniill use for automatically feeding metal plates or sheets to the rolls and for receiving said plates as they are returned through the rolls; to provide a tilting table particularly adapted for use on three-high rolls; and to provide a traveling device whereby the plates or sheets are carried from one set of rolls to another in a series.
l'Vith these and other objects in view, all of which will hereinafter be made apparent, the invention finally consists in the particular construction, arrangement and combina tion of parts which will hereinafter be fully described, reference being herein had to the accompanying drawings, forming a part of this specification, in Which Figure l is a top plan view of the table, showing it located in operative position in front of a set of rolls; Fig. 2 is a side elevation of the same; Fig. 3 is an end elevation of the same, showing three sets of rolls arranged in series; Fig. ls an enlarged front elevation of the last set of the series of rolls, showing in section the front end of the table, and illustrating the guard-tilting mechanism; and Fig. 5 is an enlarged cross section of the bar carrying the guardtilting mechanism.
Referring to said drawings, in which like reference characters designate like parts throughout the several views---l indicates a truck mounted for traveling upon a suitable track or track-rails 2 arranged in front of and in parallel alineinent with the rolls. shaft 3 extending longitudinally of said truck has its ends journaled in suitable bear ings 4t carried by said truck, and loosely, or mounted upon said shaft are the pivotally supports 5 of a tilt-table 6. Said table comprises in its construction a frame 7, a plurality of rollers 8 journaled in said frame, and side-guards 9 and 10. Said rollers 8 are suitably connected by bevel-gears ll and 12 with a shaft 13 which extends longitudinally of said table. F or driving said shaft 13, a motor 1% mounted upon the truct: 1 beneath the table 5 has its drive-shaft 15 geared to a gear-wheel 16 fixed upon said shaft 3, and a second gear-wheel 17 carried by said shaft 3 meshes with a gear-wheel 18 carried by one of said roll'ers 8 at a pointoutside the frame '4".
Located in front the rolls and in parallel alinenient therewith is a longitudinal rod 1.) adapted to serve as a support for the front end of the table 6. Said rod 19 extends the whole length of the series of rolls and is supported at each end by a chain or cable 20 which is ,arried over a pulley 2L mounted in an arm or extension of the roll housing. The opposite end of said chain is connected to any suitable mechanical power device. such as a hydraulic piston (not shown), for raising and lowering said rod 19', and, consequently, for effecting the raising and lowering of the said front end of the table.
An appropriate tube-like cable-haul depends from the under side of the truck 1 into a longitudinal pit 24 arranged between the traclerails 2 in parallel alineinent therewith, cables 25 connected to said cable-haul extending therefrom in opposite directions to suitable drums (not shown) whereby sait truck may he moved along said track. The feed-wires leading to the motor is are passed upward from the pit through said. cable-haul, as shown.
in operation, a metal sheet or plate placed upon the table 6 is carried forward on the forwardly-rotating rollers 8 to the upper pair of th first set 27 of the three-high rolls. When said sheet has passed from the table, the direction of travel of said rollers is reversed and the front end of the table is lowered for receiving said sheet as it is returned through the lower pair of rolls of said set. Said sheet having been rolled to the proper thickness in said first set 27, the direction of travel of the rollers and the position of the front end of the table being changed in effecting each pass, it is received upon the table and the rollers are stopped. The truck is then moved forward along the track to a point directly in front of the second set '28 of the series of sets of rolls, where the foregoing operation of passing the sheet through the rolls is repeated, and from which the truck carrying said sheet is moved forward to the third and last set 29 of said series of rolls, which set is preferably but two rolls high. When the sheet has been delivered to said set of rolls, the
truck is returned along the track to the first set 27 for receiving a new sheet and for a repetition of the foregoing operation. It is desirable, however, to start the return of said truck before the sheet has wholly passed from the table in its last pass through the set 29; and, in order to admit of this, the guard 10 is hinged to the frame 7 at or below the level of the tops of the rollers, as shown at 30, so that it may be lowered to a point where it will not engage with the sheet when the truck is moved rearwardly from beneath said sheet. Weights 31 depending from said guard 10 normally hold it in an upright position. For effecting the lowering of said guard from its said normal position, automatic means are provided, said means comprising a bar 32 adj ustably supported in front of and in parallel alinement with the last set 29 of the rolls, and a lever pivotally carried on the end of said bar. Said lever is pivoted intermediate its ends, as shown, and a springbolt 34 carried by an arm mounted upon the bar 82 bears against the upper edge of the front end of said lever, while a weight 36 carried by the rear end of said lever normally holds the latter in substantially the position shown in full lines in Fig. 4. When the truck is moved from the second set 28 of rolls to the third set 29, the upper edge of the guard 10 engages the under side of the front end of said lever, elevating the latter against the tension of the spring-bolt 34:. The guard 10 having passed from beneath said l ver, the latter drops back to its normal position. After delivering the front end of the sheet to the set 29 of rolls, and before the sheet has wholly passed from the table, the truck is moved rearwardly with the view of withdrawing it from beneath said sheet. As the truck is so moved, the rounded end 37 of said lever engages a pocket 38 provided at a suitable point in the inner face of said guard 10, and said guard is thereby swung back on its hinges 30, while the said lever is swung downward to substantially the position indicated in dotted lines in said Fig. 4;, the said guard being thus caused to assume a substantially horizontal position, allowingsaid truck to pass from beneath the sheet without interference. Having reached said horizontal position, the said guard slips from beneath the rounded end of the lever, and the former, actuated by the weights 31, assumes its normal upright position, while tne latter, actuated by the weight 36, swings back to its normal position.
As a guide for the sheets as they pass from the table to the rolls, a spring-guard 39 is attached at its rear end to the guard 9 at a suitable point, the inner end of said spring-guard being rendered adjustable by the employment of an adjusting-screw 40, as shown in Fig. 1.
As is obvious, various alterations may be made within the scope of the appended claims without departing from the spirit or scope of the invention. 7
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In a device of the character described, the combination with a series of alined setsof rolls, of a truck arranged to travel from one set of rolls to another, a table mounted upon said truck, side-guards carried by said table, one of said side-guards being hinged, and weights whereby said side-guard is normally maintained in an upright position.
