SELLSCHAFT,.OF DUSSELDORF, GERMANY, A CORPORATION OFv GERMANY COOLING MEANS FOR ROLLED B ARS Application filed July 12, 1932, Serial No. 622,080, and in Germany July 13, 1931.

My invention relates to cooling devices for the cooling of rolled bars, and has partlcular reference to improvements in cooling beds, on which the rolled bars are successively 5 moved along either singly, or in groups.

The object of the present invention 1s to produce a cooling device whereby rolled bars of any cross-section are gradually cooled especially when passing through the critical 1 temperatures. In this way, rolled products of high quality are obtained; My cooling device is so designed and constructed that rolled flat bars having a large surface may be gradually cooled, which object I attain in pro- 1 viding special means permitting the bars to successively glide, down an inclined plane to a place where they are arrested to be sub sequently stacked and moved across the cooling bed in stacked formation, whereby all the 0 bars are gradually and uniformly cooled, until they reach the place at the end of the cooling bed where they are removed. In this way, warping of the flat bars is effectively pre vented.

The means permitting the downward glide of the flat bars are so arranged that they can be moved to operative and inoperative positions at will. In the latter event, the cooling device is arranged for the intermittent movement of rolled bars of other than flat crosssection toward the cooling bed by means of a step-shaped connecting member, on which the rolled bars are constantly supported. Operatively associated with said connecting member are lifting elements for moving the bars one step at a time. These lifting elements are disconnected, when flat bars are cooled.

The invention is shown on the annexed drawings, on which Fig. 1 is a side elevation of the new device, the central portion of the cooling bed being shown broken away and certain portions being shown in section; Fig.

2 is a. similar view as Fig. 1 showing additional elements for adapting the device for the handling of rolled fiat bars; Fig. 3 shows,

on an enlarged scale, the right-hand part of Fig. 1 adapted for the handling of rolled bars of various cross-sections, the lifting elementsbeing shown in their various operative positions as indicated by the broken lines; Fig. 4 shows, on an enlarged scale, the righthand part of Fig. 2 to more clearly illustrate the manner of operation in the handling and stacking of rolled fiat bars; Fig. 5 is an enlarged detail view of that part of the device, where the flat bars are stacked.

In all the figures, at 1 is shown the feedroller mechanism, at 2 the roller delivery bed, at 3the removal device, at 4 the cooling bed, over which the rolled bars are transported without being lifted, and at 5 a mechanically driven rock-shaft extending longitudinally of the device and having mounted thereon the lever arms 6 and 7 which can be selectively coupled with or uncoupled from shaft 5.

The lever arms 6 have linked with them lifting elements 8 provided with vertical slots 9 which are engaged by the free ends of guidelevers 10 mounted on a longitudinally extending mechanically driven rock-shaft 11.

The lever arms 7 shown in Figs. 2 and 4 have linked to them supporting rods 12 carrying stacking elements 13 also acting as chutes. At 14 is shown a longitudinal beam and at 15 a longitudinally extending bracket provided with an inclined face 'actingas a chute. On these two elements rests a stepped plate 16 formed with a plurality of grooves 17 (Fig. 3), which are used for the handling of rolled bars of various cross-sections.

The operation of the above described device is as follows:

At 18 in Figs. 1 and 3 is shown a bar which in well-known manner is lifted out of the feed-roller mechanism 1 and on the inclined face of bracket 15 slides into the position indicated at 18. Thereupon, by means of the lever arms 6 the lifting elements 8 linked to these lever arms are lifted from their position shown at I in Fig. 3 to the position shown at IT and immediately thereafter, the lifting elements are swung by the guidelevers 10 mounted'on shaft 11 and engaging in the slots 9 of the lifting elements 8 to the 95 position shown by the broken lines marked III in Fig. 3 and by a corresponding rocking movement of shaft 5 are lowered to the position marked IV in F ig..3 from which position the lifting-elements 8 are returned by delivery bed 2 shown at the left in Figs. 1

and 2 is effected in well-known manner by the removal elements shown at3 in said figures, which elements, after each cycle, remove a certain number of cooled bars onto the roller .delivery bed 2.

To adapt the device for the handling of rolled flat bars, the following additional elementsv are provided.

At 19 in Figs. 2 and 5 is shown a shaft on which are fulcrumed glide-elements 20, which can be swung from their inoperative position shown by the broken line 20 in Fig. 4 tothe full-line position in which they cover the stepped plate 16. Fulcrumed on the same shaft 19 are the above mentioned stacking elements 13, which normally occupy the fullline position shown in Fig. 4, from which position they may be swun to the elevated position 13 as indicated by the broken lines in Fig. 4. At 21 in Figs. 2, 4, and 5 are shown movable stops corresponding in width to the distance between two adjacent removal members 3', which stops are so shaped and designed as to afford a support to the rolled flat bar, as the stacking operation is commenced, and to maintain said support while the rolled flat bars are gradually moved across the cooling bed. Directly adjoining the removal element 3 at the delivery end of the cooling bed 4 are plates 22 which may be formed integral with the roller delivery bed and are designedto receive the stops 21, when the entire cooling bed is covered in its entire width with rolled bars. In that case the stops 21 have reached their position of rest indicated in Fig. 2 by the reference numeral 21.

The rolled flat bars are shown in their various positions in Figs. 4 and 5 by the refer- . ence numerals 22, 22, 22" at thebeginning and end of an operation. At 24 in Fig. 5 is more clearly shown the manner of stacking the rolled flat bars. 1

When rolled flat bars shall be handled by the herein described device, the lever arms 6 are uncoupled from shaft 5 and in their place, the lever arms 7 shown in Figs. 2 and 5 are coupled with shaft 5, which two operations .can be performed by any well-known cou- ,pling and uncoupling means which are, therefore, not shown. By the uncoupling of the lever arms 6 also the lifting members 8 are disconnected, or made inoperative. whereas the. stacking devices 13 are :now operatively connected with shaft 5 by means of the links 12 and lever arms '4'. The guide-shaft 11 re- .mains entirely at rest, while rolled flat bars are handled, but the glide-members 20 are swung about the shaft 19 from their inoperative position shown by the broken lines in Fig. 4 to the full-line operative position shown in Fig. 4, and the device'is now ready for the handling of rolled flat bars. The operation is as follows:

' The rolled flat barsshown at 22 in Fig. 4 are lifted in well-known manner from the feed-roller mechanism 1 to the position shown on the upper right hand in Fig. 4. When now through the rocking of shaft 5 the stacking elements 13 are moved from their inoperative position (full-line position in Fig. 4) to their operative position (broken lines in Fig. 4) then the rolled fiat bar 22 will slide down from the. position shown on the upper right hand in Fig. 4-to the position indicated at 22 where it comes to. rest against the stop 13 provided on the stacking elements 13. As the latter descend, the stop 13, which may be made an integral portion of the. stacking element 13 or can be formed as a separate ledge, disappears below the inclined faces of the glide elements 20 thereby enabling the flat bar to glide down further from its position shown at 22 to the position shown at 22 shown in Fig. 5, where it arrives at the stop 21 at the beginning of the cooling bed 4. When during the next operation the stacking members 13 are again raised, the flat bar which has previously slid down to the position shown at 22 in Fig. 5 is pressed against the stack of fiat bars shown in Figs. 4 and 5, whereby the stack is moved ahead along the cooling bed 4 toward the left in Fig. 4.- Each time, the operation just described is repeated, the stack of flat bars on the cooling bed is increased, until the entire cooling bed is covered by flat bars and the stop 21 arrives in its position of rest shown at 21 in Fig. 2.

The stacked fiat bars are then removed from the cooling bed in any well-known manner. 7 Y

The advantage of my device consists in this that it is equally well adapted to two different methods of cooling rolled bars with 1 the aid of the very simple means. Also provision is made that the large heat radiation of the rolled bars onto the parts of the device has noeffect on its absolutely safe opera- 1 ti'on.

Preferably the inclined face 15 of the feed roller mechanism is provided with short 'metal pieces tosupport the rolled bars at spaced points, thereby to insure against warping of the comparatively long channel element of the feed roller mechanism by the heat of the rolled bars.

I claim:

1. Cooling means for rolled bars comp-rising, in combination, a feed mechanism for the 1 rolled bars, a cooling bed, a stepped member between the feed mechanism and the bed, means cooperating with said member to effect a step by step advance of bars entirely thereacross from the feed mechanism to the cooling bed, and a glide member separate from said means, said glide member being mounted for movement between an inoperative position in which it does not affect the step by step advance of the bars across the stepped member and an operative position in which it overlies the stepped member and extends from the feed mechanism to the bed to support bars during their transfer from the feed mechanism to the cooling bed.

2. Cooling means for rolled bars comprising, in combination, a feed mechanism for the rolled bars, a cooling bed laterally spaced from the feed mechanism, means for advancing bars step by step entirely across the space between the feed mechanism and the bed, and means separate from said first mentioned means for advancing bars over said first mentioned means entirely from the feed mechanism to the bed.
