I '0 all whom it may concern:

Be it known that I, JEROME R. Guouen, a citizen of the United States, residing at WVorcester, in thecounty ofWVorcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in Cooling-Beds for Metal Rods or Bars, of which the following is a specification, ac-

companied by drawings forming a part of cooling takes place.

The objects of my invention are to pro vide an improved receiving table to receive the rods from the rolling mill; to provide an improved transferring mechanism for moving the rod sidewise from said receiving table, and also to provide means for the reception of a succeeding rod before the removal of the previous rod from the receiving table. These objects, among others, I accomplish by means of the construction and arrangement of parts as hereinafter described, the novel features being pointed out in the annexed claims.

Referring to the accompanying drawings, Figure 1 is an end elevation of a cooling bed embodying my invention, shown in sectional view on the plane of the broken line 33, Fig. 2. Fig. 2 is a side view of the upper part of my improved conveyer. Fig. 3 is a detached view of the receiving table and transferring mechanism shown in vertical, sectional view on the plane of the broken line 3-3, Fig: 2, with the transferring mechanism in its normal position. Fig. 4 is a similar sectional View, but with the transferring mechanism at the end of its swinging movement after transferring a rod from the receiving table to an adjacent trough. Fig. 5 represents the receiving table in sectional view on the plane of the broken line 5-5, Fig. 2, with a transferring mechanism adapted to receive a second rod from the mill before the first rod has been. transferred from the receiving table. Fig. 6 is a similar view to that shown in Fig. 5, but

with the transferring mechanism shown at the end of its operative stroke. -Fig. 7 is a vertical, longitudinal, sectional view through the receiving table, on the plane of the broken line 7-7, Fig. 5. Fig. 8 is a vertical, longitudinal, sectional view through the receiving table, on the plane of the broken line 88, Fig. 3. Fig. 9 is a longitudinal, horizontal, sectional view on the plane of the broken line 99, Fig.

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

Referring to Fig-1,1 have shown such portion of the operating mechanism of a cooling bed as is necessary to illustrate the nature of my present invention, a portion of the supporting framework and uncssential parts of the operating mechanism having been omitted for the sake of clearness. In the remaining Figs. 2 to 8, inclusive, Ihave shown only those portions which are concerned in my present invention in detached views and upon a larger scale.

Referring to Fig. 1. which represents an end view. of the cooling bed, 1 denotes a supporting framework, 2 one of a series of inclined notched bars to which an oscillating movement is given by suitable mechanism to transfer the'heated rods from the upper to the lower notches by a step-by-step movement, the time required for the sidewise movement of the rods from notch to notch across the bars 2 allowing the rods to cool. The rods are first received from the finishing rolls of the mill by a longitudinal movement over a series of conveyor rolls. one of which is shown at 3, Fig. 1, said rolls 3 having. an intervening receiving table 4. Supported upon the conveyer rolls 3 and the intervening receiving table 4 the rods occupy the position indicated at 5, Fig. 1. From the position shown at 5 the rods are moved onto an inclined table 6, terminating at its lower edge in a trough 7 into which the rods slide by gravity. The rods are moved from the receiving table 4 by a swinging plate 8 at tached to arms 9, which are carried upon a' rock shaft 10 operated by the attendant through a lever handle 11.

The receiving table tudinal sectional view in Figs. 7 and 8, upon which the heated rods are received in the direction of the arrows a. The receiving table 4 is provided with a series of raised 4 is shown in longiQ the conveyer rolls 3 and arranged 'to support the weight of the heated rods between said conveyer rolls in a plane above the lower ends or tips 13 0f the swinging plate 8. The sides of the raised portions 12 opposed to the longitudinal movement of the rod are beveled as shown at 14, to conduct the advacing end of the rod over the raised portions 12. The swinging plate 8 is provided. with forwardly extended portions 15 having their sides opposing the longitudinal movement of the rod beveled, as shown at 16, Fig. 8, to facilitate the movement of the rod past the forwardly extended portions 15. The swinging plate 8 and the receiving table 4 do not resent any obstruction to the longitudinal movement of the rod in the direction of the arrows a. The inclined table 6 is provided with transverse slits or openings 17 to provide for the swinging movement of wings 18,-Fig. 1, attached to the notched bars 2, for the purpose of lifting the rods out of the trough 7, the construction and operation of said notched bars 2 and wings 18 being substantially like that shown in the United States Patent to Victor E. Edwards, No. 701,024 issued May 27, 1902.

' When a heated rod has been received from the rolling mill upon the conveyer rolls 3 and receiving table 4, it sometimes occurs that the advancing end of the next succeeding rod from the mill is projected upon the cooling'bed before the mechanism fortransferring the first rod from the'receiving table has returned to its normal position. In

order to'prevent the overlapping rods from colliding I use a transferr1ng mechanism in the first two sections of the cooling bed, as represented at the right hand end of Fig. 2, and in larger and sectional views in Figs. 5, 6 and 7. The swinging plate which is used in the remaining sections of the cooling bed and is shown on an enlarged scale'in Figs.'3, 4, 8 and 9 is connected to a different form of swinging plate used in said transferred mechanism. Said swinging plate consists of a pusher plate 19,.having at'its upper edge a curved platform 20 con centric with the axis of the shaft 10- about which the pusher-plate swings. The curved platform 20 isreduced in" height with its receiving end bent downward zit-21, Fig. 7, in order to enable the' succeeding rod as it leaves the first conveyer roll 3 to be received upon the platform 20 instead of the receiving table 4, provided the pusher plate 19 has been advanced sufliciently to bring the platform over the receiving table 4, or in the position shown in sectional viewlin Fi 'i6. I

5 gupported by the'rigid framework of the cooling bed above the receiving table" 4- and also above the curved platform 20, when in its advanced position, as shown in Fig. 6-, I provide a housing 22 consisting of an inverted trough open at the bottom, beneath which the succeeding rod is projected and caught upon the curved platform 20 in the position shown at 23, Fig. 6. e

If the pusher plate 19 and platform20 swing back into the position shown in Fig.

' 5, the rod 23 falls and is caught upon the conveyer rolls 3 and receiving table 4 in the position shown at 24, Fig. 5, the side 25 of the trough shaped housing 22 serving.

to'scrape the rod from the platform 20 as it swings backward. I

The receiving table 4 and the curved platform 20, when the latter has been advanced in the position shown in Fig.6, form an upper and' lower deck, the" lower deck or table 4 receiving the rod .from the mill when the transferring mechanism has been swung back into its normal position, and the upper deck or platform 20 receiving the rod when the transferring mechanism has been swung forward, as shown in Fig. 6.

The overlapping of the rods from the mill will be confined usually to the first two sections of the cooling bed. Throughout the remaining sections of the cooling bed the platforin-20 is not required and the transv.

fer-ring mechanism consists of the swinging plate 8 carried upon arms 9 attached to the.

rocking shaft 10. The pusher plate 19 at the front edge of the platform 20 is constructed like the swinging plate 8, that is, it has forwardly extended'portions 26 corresponding with the portlons 15 on the swinging plate 8. and having the sides opposing the advancing end of the rod beveled as at 27. The receiving table 4 and also the supporting surface of the conveyer rolls 3 areinclined toward. the swinging plate 8 and the pusher plate'19 so that the rod projected over these surfaces tendsto slide toward the inner ends of the rolls and therod is held in-contactwith the transferring mechanism, as shown at 24, Fig. 5,-

and 26, Fig. 3. In this position the ad- I -vancing end of the rod i'smoved over the raised portions l2of the receiving table and also. in contact with the forwardly extended portions 15 of the swinging plates 8 and theforwardly extended portions 26 of the pusher plate 19. .The advancing end of the rod is thereby prevented from striking any projecting shoulder of the cooling bed or being caught between the receiving table and the transferring mechanism. 1

When theheated metal transferred to th cooling bed consists of thin strips of the character of band iron,'-for example, it is important that means be provlded'to-p'revent the advancing end, even when bent or deflected from 9. straight 'lin'ef from being expanded by heat crack oropening, however slight, between the receiving table and the pusher plate. The space between the receiving table and the edge of thepusher plate must be of sufiicient size to'allow ample clearanee when theparts have been and, in order to remove any possibility of the advancing end of the rod from being caught in the open space, the lower edge of the-pusher plate extends below the supporting surface of the receiving table; the forwardly projecting portions 15 of the pusher plate alternate with the raised portions 12 of the receiving table; and the forwardly projecting portions 15 overlap the beveled. surfaces Ll of the receiving table. By means of the above construction, the beveled surfaces-13 and M move the advancing end of the heated metal away from the open spaces between the receiving table and the pusherplate.
