FEEDING MECHANISM FOR ROLLlNG--M|LLS.

S$IPEGIFIOATION forming part of Letters Patent No. 740,418, dated October 6, 1903.

I Application filed July 3, 1903. Serial lio. 164.132. (No model.)

To aZZ' whom it may concern.-

Be it known" that I, JEROME R. GEORGE, a citizen of the United States, residing at Worcester, in the county of Worcester and Commonwealth of Massachusetts, have in vented a new and useful Improvement in a Feeding Mechanism for Rolling-Mills, of

which the following is a specification, accom panied by drawings forming a part of the same, in which- Figure 1 represents a plan view of my improved feeding mechanism for rolling-mills, representing a roll-housing shown in horizontal sectional view on the plane of the passes between the rolls; and Fig. 2 is a side view shown in section on line 2 2, Fig. 1.

Similar reference figures refer to similar parts in the different views.

The object of my invention is to provide a feeding mechanism by which heated billets may be delivered from the delivery-opening of a furnace to a pair of rolls having two operative sets of circumferential grooves or passes, by which the billet is directed into either one of the two sets of passes at the will of the operator, and the feeding mechanism embodying my invention is an improvement upon the feeding mechanism designed for a similar purpose and shown and described in United States Letters Patent No. 653,507, granted to Victor E. Edwards July 10, 1900.

Referring to the accompanying drawings, 1 denotes a billet-heating furnace having a mouth or opening 2, through which the heated billets are withdrawn by an endwise movement upon a supporting-table 3, from which they are fed to a pair of rolls 4, journaled in a housing 5 and having a pair of operative passes or circumferential grooves 6 and 7 to which the heated billets are'longitudinally fed.

In the presentinstance the rollsare provided with other grooves 8 and 9, which may be brought into operative position by changing-the rolls end for end; but for the purpose of the present illustration only grooves 6 and 7 are to be considered. Arranged in front of the rolls are guide- plates 10, 11, and 12, between which are the passage-ways 13 and 14, through which the billets are conducted to the grooves 6 and 7. The passageways 13 and 14 are provided with the flaring months 15 and 16, intowhich the heated billets are conducted by the attendant from the table 3, or in lieu of the guide- plates 10, 11,

and 12 the delivery end of the table 3 may be brought sufficiently near tothe passes of the rolls to enable the billets to be delivered directly from the table to the rolls. One corner of the table 3 is cutaway to provide space for a plate 17, having its upper surface normally in the same plane as the surface of the table 3 and provided on one side with an upwardly-projecting flange ,18 and having a portion 19 of the side opposite the flange 18 arranged obliquely to the line of motion of the billet as it passes across the plate 17 into the pass 7 of the rolls, The remaining portion of the opposite side of the plate 17' is provided with a raised flange 20,- between which and the flange 18 a billet may pass from the table 3 across the plate 17 and be conducted to the pass 7 of the rolls. The table 3 is .provided with a diagonal opening 21, through which a plate 22 projects upwardly above the surface of the table 3 and serves as a guide to deflect a billet, whichmay be longitudinally pushed or otherwise moved across the table, sulficient space being left between the flange l8 and the end' '23 of the oblique plate to permit the passage of the billet across the plate 17. The plate 22 extends downwardly beneath the table 3 and is hinged at one end beneath the table to a bracket 24. The free end of the plate is provided with a curved arm 25,: connected by a wire rope 26 with lifting means (not shown) for raising the plate 22 to bring its upper edge above the table 3. The plate 17 is likewise pivoted by arms 27 27 to brackets 28 at the opposite side of the table 3, and the plate 17 is which may be connected by a wire rope 30 with lifting means (not shown) for raising 9 the plate 17. In the drawings the vertical likewise provided with an arm 29,

the plate 17 between the flanges 18 and 20 to the pass 7 of the rolls. If it is desired to push a billet forward and conduct the same to the pass 6 of the rolls, the vertical plate 22 is lowered to bring its upper edge below the surface of the table 3, and the plate 17 is raised above the surface of the table 3, so

that its oblique side 19 will serve as a guide to deflect a billet toward and in line with the pass 6 of the rolls. The table 3 is also provided with an upwardly-projecting flange 31, placed at an opposite inclination to that of the side 19 of the plate 17, so that the plate 17 and flange 31 constitute flaring guides, between which the billet is conducted into alinement with the pass 6 of the rolls.

The operation of my feeding mechanism is as follows: Assuming the plate 17 to be lowered to a level with the table 3, the vertical plate 22 to be raised above the table 3, as shown in the drawings, a heated billet is pushed from behind through the mouth 2 of the furnace upon the table 3. If its advancing end strikes the plate 22, it will be deflected and made to enter between the free end 23 of the plate and the flange 18, passing over the plate 17 through the space between the flange 18 and the flange 20 into the pass 7 of the rolls. The plate 22 is then lowered, the plate 17 raised, and a second billet can be pushed forward between the raised plate 17 and the flange 31 in alinement with the pass 6 of the rolls. In case it becomes necessary that the second billet should cross the path of the first entered billetbefore the latter has been drawn 01f the table 3 this can be accomplished, as the raising of the plate 17 lifts the first entered billet sufficiently high above the plane of the table 3 to allow the second billet to pass beneath it and in contact with the inclined edge 19 0f the plate 17, space being provided therefor by the lifting of the first billet due to the elevation of the plate 17, and any tendency to displace the first entered billet will be resisted by the flanges 18 and 20, betweenwhich the billet will be held in proper alinement with the pass 7 of the rolls.

What I claim as my invention, and desire to'secure by Letters Patent, is-

1. The combination withapair of rolls having two sets of circumferential grooves forming passes for a billet, and a billet-supporting table in front of said rolls, of a verticallymovable plate normally held in the plane of the supporting-table, raised flanges onsaid movable plate between which a billet is conducted to one of the-passes in said rolls, and a vertically-movable guide-plate by which the advancing end of a billet is deflected upon said movable plate, substantially as described.

2. The combination with a pair of rolls, having two separate passes for a billet and a billet-supporting table in front of said rolls, of a movable plate capable of being raised from a position flush with the table to one above said table, and having one of its edges oblique to the line of motion of a billet across said table, a vertically-moving oblique guideplate moving in an opening in said table and a fixed guide on said table opposite said verticallymovable plate, substantially as described.

3. The combination with a pair of rolls having two separate passes and a billet-supporting table in front of said rolls, of a plate capable of a vertical movement from a position flush with the table to one above the table, a raised guiding-flange on saidplate by which a billet is directed into one of said roll-passes, a guide for directing abillet across said plate, said guide being capable of being depressed below the surface of the table, and a fixed guide on said table whereby a billet is directed into the other of said passes in the rolls, substantially as described.

Dated this 27th day of June, 1903.
