HOT BED.

Application led December 18, 1926, Serial No. 155,690, and in Germany December 15, 1985.

My invention relates to improvements in mechanically operated hot beds for iron rolling mills upon which the hot metal bars,

rai-1s, etc. are deposited as they come from the rolling` mill and from which the bars are laterally transferred to the cooling bed pro r. I

e obj simple and efficient means for receiving two or more rolled metal barsat a time and by which these bars can be easily handled, i. e..

ided and straightened while in transitom the mill and can be delivered under' the control of the operator to the cooling bed.

Another object of my invention is to -pr o' Ivide a durable apparatus for the purpose set forth which is of. such construction as to readily withstand the wear dueto the frictional contact with th'e hot bars and to the shocks to which apparatus of this character are generally subjected.

Other objects o f 'my inventionvmay ap? pear hereinafter.

The nature and scope of my invention is briefly outlined in the appended claims and will be more `fully understood from'the fol-v lowing specicationtaken together with the accompanying drawin in which- F ig..1 is a cross sectlon through ahot'bed according to my invention. Figs. 1 and '1? are cross sections of'struc- Fig. 2 is a longitudinal section taken along Fig. 3 shows a structurally modified hot bed in cross section Fi 4 is a longitudinal section of a structura y modified hot bed of the' type shown.

in Fig. v3;

Figure 4 is a cross section through the hot bed shown in Fig.. 4.

Referring to Figs. 1 'and 2 the het bearer.;

shown by way of an example comprises t'wo receiving troughs 2 and 3, 'arranged alongside the cooling bed 1'; jsaid' troughs are composed of vstationary supporting members 4, 4" and. movable 'Supporting members 5,

l5', the-latter being shiftably mounted upon carriers 6, 6', .whlch arecooperatively connected-with a plurality of bell crank levers 8,' 8 upon the shafts 7, 7'. Intermediate-of the receiving troughs 2 and 3. a stationary wall 9v is arranged, .which 'projects vabove said troughs, separating the latter from each;

`thumbs 12, so as to be capable of bein lifted.

ect of my invention is to vprovide `t-hen shiftedinto their lowermost position tural y, modiedform of-a hot bed, as described hereinbefore with reference to Figs.v

other and which carries at its top an inclined delivery plate 1 0, the latter being preferably pivotally connected by bolts 11 and supported in its working position by upwards by hand or suitable mec anical means-not shown.

By placing the tiltable delivery plate into its upright position the receivingA trough 3 becomes easy of access and inspection. x

' While the'rolled. bar's hereinafter referred to as .material proceed from the rolling mill into the het bed and are deposited on the stationary supports 4, 4 of-the receiving troughs 2 and 3, the movable members 5, 5

of the latter are in their upper position as indicated in the drawing in dot and dash lines. The. material in transit from the mill by reason of v4the action of the obliquely arranged co'nveyingrollers 13--known per se in the art-will be pushed against the flat. lateral" faces of the movable members 5, 5 and will thus be guided and straightened throughout its'full length. In order to transfer ille material onto the cooling bed 1 thefmovable members 5, 5 are shown in full lines. There upon viz, by the action of the conveying rollers 13 the material will automatically move laterallyuntil it comes to rest against the vertical face of the wall 9 and the verticali face 14 of the cooling vbed respectively.

Hereafter the movable members 5, 5 are lifted so as to be flush with or slightly above .the upper Vsurface ofthe wall 9, 1. e. the delivery plate 10, and of the cooling bed 14, respectively, Thereupon the material will automatically slide down upon the slopin top' faces of the movable members 5, 5 and the deliver plate 10 `respectively until it inall reac es the cooling bed 1. A struc- 1`and 2, is shown in cross section in Fig. 3. The receiving troughs 2 and 3 are in this vcase arranged 1n stepped position with res ct to each other and the cooling bed v1. he conveyingv rollers 15 are inclined and have a conical surface' offset to suit the stepped 'arrangementv of the discharging troughs.

` The partition wall 9 andthe movable UQ L members 5, are conformably mounted and shaped so as to present inclined top and side faces. As seen 1n Fig." 3 the movable members 5, 5 are operated similarly to those shown in Figs. 1 and 2 viz by means of rocking levers 16, 16 mounted upon shafts 17, 17 The operation of the whole mechanism forming the hot bed is exactly identical to that y ex lained with reference to Figs. 1 and 2.

an other' structural modifications may be ma e in the design of hot beds Idescribed above and in the cooperation of their, component parts without substantially departing from the spirit and the leading ideas of m invention.

,ylhus e.- g. in Fig. lla hot bed is shown by way of an example, 'composed of three receiving troughs 20, 21, 22 which areseparated from each other by partition walls 423, 24, each of the latter being provided at the to with a tiltable delivery plate 25, 26. T e delivery plate 25 rojectsbeyond the adjacent receiving troug 21 so as to deliver the material to the second delivery plate, both delivery plates 25, 26 being made and `arranged in stepped relation.

It will be obvious to those skilled in the art that more than three receiving Atroughs may bearranged, if called for, in order to simultaneously deposit a plurality' of metal bars or the like comingfrom the rolling mill.

1b another modification of a hot ImFi de according to 'this invention is bed ma .i shown, in which the material is dropped from each delivery plate directl onto the cooling bed `1. For this purpose t e delivery 'plate 29 of the partition wall 30 yond the receiving trou h 22.

plate 27 'of the partition wall 28 is made Wide enough to' roject beyond both adjacent receiving troug s 21, 22 while theA delivery projects be- Thus ythe material rom each receiving rugh is delivered directly to the cooling In Figs. 4 and 4 a structurally modified mechanism is shown in longitudinal and cross sections respectively for lifting the material from the receiving trou hs onto the deliver plates. In this modi cation the movab e supporting members referred to vabove with reference to Fi s. 1-3 arejreplaced b a number of tiltab e lifting plates 31, whic are preferably pivotally attached to the receiving trough.

As seen in Fig. 4 the tiltable lifting plates 31 extend approximately over half the-widthreceiving troughs 32,l 33

of the stationar being located a 'acent to and alongside of the partition wall respectively. l a

vSaid tiltable plates 31 are formed and arranged so as to present. intheir lifted position an inclined upper edge 36 slopin towards the cooling bed on which the lifted material WillAs/lide down tothe latter.

34i and the cooling bed 35 Suitable means e. g. a hydraulically or electrically driven actuating mechanism known per se in this art and being under the control of the operator may be provided for o erating the levers 8, 16 and the tiltable p ates 10, 25, 26,29, 31 referred-to hereinbefore.
