TRANSFER-TABLE FOR ROLLING-MILLS.

Specification of Letters Patent.

Application filed April 29, 1905.

Serial N0. 258,073.

To all whom it may concern:

Be it known that 1, CHARLES L. linsroiv, a citizen of the United States, residing at Coatesville, Pennsylvania,-. have invented g -sufiicient distance apart so as to allow for;

the insertion of a transfer table E which extends from one roller table to the other;

certain Improvements in Transfer-Tables for Rolling-Mills, of which the following is a specification.

My invention relates to certain improvements in transfer tables for rolling mills by which a plate, after it has been rolled, can be transferred to the shears and given suiticient time .in its transfer to properly cool I before being cut. 7

The object of my invention is to provide a table which can be readily manipulated so as to transfer a plate from the. rolling table of the mill to the roller table of the shears, and to provide means for examining the underside of the plate while on the table. This object I attain in the following manner, reference being had to the accompanying drawings, in which 1*- Figure.1, is a diagram plan view of my improved transfer table for rolling mills;

Fl 2 is a. plan view of a: portion of the rolling mill end of the table; Fig. 2 is a plan view of the middle section of the table; Fig. 2, is a plan view of a portion of the shears end of the table; Fig. 3, is a longi tudinal sectional view of the table shown in Fig. 2*; Fig. 3 is a longitudinal section view of the table shown in Fig. 2"; Fig. 3, is a longitudinal sectional view of the table shown in Fig. 2; Fig. 4, is a longitudinal sectional view showing the means for raising and lowering the rolling mill end of the transfer table; Fig. 5, is a longitudinal sec-' .tional view showing the gearing for operating the enchained rollers and the means for operating the lifting arms for raising the plate when it is to beexamined; Fig. 6, is an enlarged sectional viewon the line 6-6, Fig. 4; Fig. 7 is an enlarged sectional view on the line 7-7, Fig. 5; Fig. 8, is a detailed the table D are driven by a longitudinal shaft d from an engine a under the control of the operatorat a suitable point, .while the rolls 0 of the table G are geared to a longitudinal shaft 0 and are driven by'an en-' ine b. The tables C and D are spaced a The transfer table is of sufiicient size to allow the plates to cool whilebeing trans ferred from the rolling ,mill'to the shears.

Patented Dec. 2, 1909.

This transfer table is m'a'de up of two sections E and E andthe-rolling millend F of the section E extends betweenthe rolls of the table D and can be raised and lowered so that it can lift a plate offof the rolls in order that it can be moved onto the body of the transfertable, While-the shear end F of the section E extends between the rolls of the table C so that a plate can be moved from the'transfer table onto the shears table. The sections of the transfer or'eooling table are made up of-a series of frames spaced a given distance apart, upon which travel en-' chained rollers. The individual chains do not extend from one end of the table to the other but extend from one end to the center, each section E carrying a series of endless chains, the chains being driven from .a central shaft G which in turn is driven from av power shaft G. geared to anengine Gr under the control of the operator.

H is the lifting mechanism consisting of-a shaft and a series of arms with mechanism for} turning the shaftfso that the arms can .be raised. By this 'constructionthe plates can be raised oif of the rollers of the table 'and the underside of the plate inspected be-' fore it is sheared and whil'e still undergoing half of'the transfer table I the cooling process. 'I preferably provide a latform r on one or the men to Walk upon when marking ofi the plates for shearing and while examining I the plates.

It will be'noticed in the diagram thatjthe in the present instance, 1, 2 and 3, so that in fact there are several independent cooling tables arranged side'by side and the mechanism is so constructed that the mechanism of any one of the tables can be operated without operating the others, or the mechanism of the several tables can be driven in unison. By this construction it will be seen that if short plates are being rolled only one section at a time may receive the plates, the roller table I) of the mill being driven f0r- 'ioo table is divided into three longitudinal parts, 5

The chains I travelon the beams of" the section E of the table and pass around driving sprocket -wheels J on the shaft G, as clearly illustrated in Fig 2".

The arms ofthe endportion F' are com. '1

In order to compensate for any wear 0 the. chains provide means for adjusting the sections F and F toward and from the cen- ,tral fixed section of the table. In the pres- 1aent instance the block carrying the pivot is arranged to slide in suitable bearings in'the 4 l endstandard e of the frame Eand setscrews care provided for adjustin the block, similar .set screws are provide at the opposite Byythis means all the osite end a bevel wheel a which meshes :with the bevel wheel-mloose on the power shaft G, on: the hub of the .wheelm'is a clutch face with which cane'ngage th $30.. of -a clutch .N Y splined to the e face shaft.

H is a shaft mounted inibearings it, carried by a suitable foundation and secured to the shaft is aseries of arms H spaced a sufficient distance apart so that two or more of the arms will plate, arranged preferably in close proximity to the beams e of the table. Each arm H is shaped to form an undercut throat 72. so that when the arm is turned as shown by dotted lines in Fig. 5, the arms will not interfere with the position of a be examined as the arm when raised can extend over the succeeding plate. On the shaft is a toothed segment it with which engages a rack is carried by a plunger K arranged to travel in 6 the hydraulic cylinder K.

On operating .the mechanism the plunger K is forced out, causin the shafts H to rock and the arms whic 1 are normally be- 70 low the upper surface of the rollers of the chain are turned up into a position at an angle in respect to the face of the table, as indicated by dotted lines in Fig. 5. If a late is on the table directly above the'arms when they are" operated they will carry the plate up with them to such an angle that the underside of the plate can be examined by the operator. A,heel h is formed on each arm, which acts as a stop for the plate when itis elevated,.so that the;plate will chain when be operated while the plate is'elevated. f The stop does ,of the 35 asthe arms are plate or chain in any sense i on the shear sideof the shaftLH".

The machine is arranged sd ibat' fthe directionof movement of theehams can be raised the arms are raisedfirst' a suiiicient distance so as to allow the heel h" to extend a between two plates and thenfthe mechan .lSIIl is preferably reversed so as to movethe which is directly above 5 the armiesagainst the heel, thus when the arm israised theplate will not slide on the arm 'and strike the heel. u I i l Thefshaft carrying the sprocket wheel need not be absolutely at the center of the.

It'will be seen by the above mechanism the-rolling mill directly onto the rolling milltable and thenshift it onto'the transfer or cooling jt'able allowing the plate to :rep tablefor any length of time desired," examine theplate while on the it onto the cut to .2 the proper size. 1 p In Fig. 9, I have shown 'a' modification of the lay-out of the tablein which a re-transfer sectionis shown. In this instance there is a shear table in direct line with the roll ing mill table, but driven independently a thereof. There is a shear table at one side as in Fig. 1', and there are two separate transfer tables one entirely independent of the other. The shear table at one side may be simply a longitudinal transfer table, in some instances, and when this lay-out is usedI preferably use two shears, so that if necessity requires both shears can be operated to cut plates from one rollin mill. In this instance the plates are move from the mill to its roller table I) and then arms H -a're' to be ad I f '1. The combination of a rolling mill table,.

"sented to the shearing machine instances, in light plates, it may not be necessary to use the transfer tables at the side, and 111 this case the plates can be moved directly from the rolling mill table D to the shear table 0, which is in line with the rolling mill table.

I claim as my invention ashears table, a transfer table between the two, endless carriers on the transfer table for moving a plate from the rolling mill table to the shears table, and means placed between said carriers for elevating the plate while on the transfer table so that the underside of the plate can be examined, said I means being lndependent of and normally below the carriers.
