COOLING-BED.

To all wkom'zz may concern Be it known that I, EDWIN E. SLIGK, a citizen of the United States, residing in the borough of lVestmont, in the county of invented certain new and useful Improvements in CoolingBeds; and I do hereby declare the following to he a full, clear, and. exact description ot' the invention, such as will enable others skilled in the artto which it appertains to make and use the same.

My invention relates to. new and improved. construction and form of conveyor, particularly adapted for mechanically handling hot metal bars as they are delivered from a rolling mill and transferring them both longitiu'linally and transversely as may' be desired, and durin said transfer to maintain the bars straig it and allow the same t0, cool by the circulation of air or other cooling lmedium.

My apparatus is especially adapted to rebillets, rounds, squares, flats, I-heams, chan-- nels, angles, rails, and is also applicable to any other sections and forms of material,` as they are delivered thereto, and by means of my apparatus they may be further guided and transferred longitudinally, then groups, being cooled, if desired. 'and maintained straight lu-ring said transit, after which they are delivered either singly or in groups to the shears or warehouse for storing, loaded as many he expedient or necessary, and in order to simplify -the description, IV will refer to such products generally as bars.v

l'teferring'now to the accompanying two sheets of drawings which form partot this specification z-F ignre l is a top plan view of a portion of my improved cooling-bed, with each of its ends broken away for clear-- ness of illustration, the righthand sid'e being substantiallycomplete in details, whilethe lefthand side of this view shows a portion of my cooling-hed with its Shifters, shifterrods, 'ulcra and the top guard tlhannel re-l moved-L to more clearly expose the basis 0f the structure. Fig. 2 is a vcrtic'at transverse sectional elevation 'taken on the line I-II of Fig. l, with the exception that all the Shifters on both sides of the' cent-ral line. of the cooling-hed are sliown'in'place andin intermedi-ate posi-tiens. 3 is s; vert-isi cal transverse sectionalelevation on an en- Specication o f Letters latent.

larged scale, as compared with Figs.' 1 and` l 2, of one side of the cooling-hed, and is taken on the line III- III of Fig. l showing in full lines'the lowest posit-ions of Shifters, and in dotted lines the highest positions of the same. Fig. 4 is a longitudinal -sectional elevation on a still larger scale,

this view being taken 'on the line lV-IV of Fig. 3, showing two sections of the cooling-bed frame-work and the mechanism for operating the Shifters. Fig. 5 is a longitudinal sectional elevation of the portion of trough containing the shifter opening in the bottom thereof, showing the inclined portion of the trough for directing the bar therethrough Without interference from the edges of the said opening, the arrow indicating the direction of the movement of the bar 19. Fig. G shows a number of forms of notches, holloWs, serrations, spacers or separators, any of which, or their equivalents, I can use in my apparatus.

This cooling-bed, as shown in Figs. l and o 2, is adapted to transferY hars laterally in both directions from the central delivery rollers and trough, thereby more fully utilizing the delivery mechanism and space for the purposes desired.

Referring nowto the various characters' of reference on the drawings :.--l indicates' the side hase frames, shown in-this case as metal castings; 2 is a central base frame of somewhat similar construction; 3,. and 4' are the centra-l longitudinal sills shown as angles; and 5 are the longitudinal side sills also shown-as angles. The central driving sheaves are indicated at 6, these sheaves being' mounted on the same shaft as the flanged receiving rollers' 9 which they, are' adapted to driv T is a cable or belt preferably of Wire rope adapted to drive the sheaves 6 and thereby rotate the rollers 9 for the purpose 0f conveying the-'bars onv said rollers, the bars heing guided by the hott-om and sides of the receiving trough l0. lThe cable 7 is driven by any suitable means (not. shown) and is guided, and the tension-maintained therein bymeans of the sheaves 8. vThe receiving trough I0 is provided with openings in the bottom at. intervals as shown,t.hrongh which the end shift-ersopeirate to lift the bar-from said trou'gha-nd rollers- 9 and' deposit 4it inf;

In order that the bars which move longitudinally on the rollers 9 and on the receiving' trough 10 shall not he deflected through the openings in said trough, or by the sides of said openings, the bottom of the trough adjoining said openings is provided with downwardly inclined portions as shown vat 11 iq Fig. 5, which 'thereby serve as guides to maintain the bar 19 in said trough as it moves therein in the direction of the arrow.

The cooling-bed frame-work is preferably formed in sections as shown, each ofv said sections being supported on and secured to one of the center sills 8 and the inner side sill 5 and comprising the upwardly extending ribs or plates 12, each 'of which is provided with a series of notches or serrations 13, which serrations are alined both longitudinally and horizontally, so that a bar lying in the lower apices of a series orn adjoined notches will be maintained straight thereby. The portions 12 of the cooling-bed are narrow or comparatively thin laterally, but at the same time deep, thus conducing to Strength, while permitting by this construction a free circulation of air or other cooling medium.,

Each section of the cooling-rack or framework is preferably formed of three plates 12 connected at their ends by the webs 37 and, in order to maintain their shape, they may also be connected' together near their inter mediate portions by the ribs 38. Each of the sections of the cooling-rack is provided on its exterior with a projecting flange 39 which flanges l'orm supports for the shiitenrods 15, said flanges being recessed or cut away -ncar their central portion as shown at 11i to allow the passage of the downwardly pro- I jecting ears or lugs 20 of the shifter-rods'.

A series or plurality of shifter fingers 17 are pivoted below the notches to the shifterrods 15 by means of the bolts or rivets' 16 and said Shifters 17 are adapted to Contact their intermediate portions with the fixed fulcra or pins 18 secured in the framework 12 for this purpose, as shown. The bars adapted to be transferred and cooled are indicated at 19 and although these bars are shown in the illustratiii as being either square orround, they inay be of any sect'on or material.

The downwardly depending lugs or ears 2O of the shiilitoihrod 15 are provided with cylindrical holes through which bolts or pins 21 are nassed, which pivot.Y one end ot the link thereto, the other end of the link being pi voted to the rocker-arm'Qsl by means of the pin or bolt Q3. A main rock shaft. 25 isrnonnted in suitable bearings as shown and is provided with a crank arm 26 secured thereon, to which crank armga ,pitman or connecting rod 2S is pivoted lay means of 'the pin '27. The other end of the said conpower not shown.

The delivery trough is indicated as 31, which is provided at intervals with delivery conveyor rollers 32 which are driven by the bevel gears 33 which mesh with the corresponding bevel gears 34' mounted on the driving shaft 85, while 36 1s a top guard or coverover the driving mechanismA shown in` this case as a channel.

Itshould be noted that the interior Shifters 17, which adjoin the delivery trough 10, are preferably at a Hatter inclination, or lower than the other Shifters, when in their lowered positions, this being du'e to the fact that the fulcra. 18 for these Shifters are lower than the other fulcra andthe end shifter-lingers 17, adjacent'vto the delivery troughs,-are longer than the other shifterlingers, as shown. The object and effect of this is to permit the end Shifters to be lowered below the receiving rollers 9 and receiving troughs 10, as shown in Figs. 2 and 3, this and their eXtra' lengths thereby en- 1 abling them to extend the entire width of the trough and contact withthe bar 19 during their upward movement, in order to deliver the bar to the irst not'ch .of thc cool ing-bed. The trough 10l1aving4 some width@4 in order to accommodate bars delivered thereto, lthe distance'from the extreme edge of the same to the first. notch 13, is greater than that between the succeeding notches, so that the letthand linger 17 is made longer in order to reach the bar, no matter what position it may have in said trough, and in its extreme lower position the outer end of said finger is preferably lower than thev other fingers, in order to provide clearance and insure that it properly contacts with the bar, though the same may be slightly crooked due to deflection when heated. The receiving trough 10 is provided with an upwardly inclined side 40 as shown, to serve as an additional guide in transferring the bar -from said trough and rollers 9 to the first notch of the cooling-bed, and, the delivery trough 31 is similarly provided with an inclined side 41 to facilitate the delivery of the bars thereto.

The operation of my apparatus' is as fol-A lows -Assuming the position of thel parts to beas indicated in Fig. 3, hot bars are delivered from the rolling mill in the direction of the arrows shown in Fig. 1, and after the last end of a bar has reached the coolingbed, the crank 30 is caused to revolve, thereby rocking the shaft 25 by means of the crank arms 2G and the connections as shown,

noventa which rocking of the said shaft causes a corresponding movement of the rocker arm 24, which thus gradually slides the shifter-rods 15 on the supporting angles 39.' The Shifters 17 being pivoted at their lower ends to the shifter-rod 15,' their lower ends move forward with said bar, while their intermediate portions contact with and slide on the fulcra 18, these Shifters thus forming levers of the first class, -with the addition of the sliding motion as stated. The upper and outer'portions of the end shift-ers 17 then contact with the lower surface of the bar -19 on the receiving rollers and in the trough and by a continuation of the movement justmovement therefore, causes the upperends of the Shifters 17 to be vintroduced below the bars 19 and insures this action, after vWhich the continuation of the movement of the shifter-rod causes the shifters to roch:`

in increasing degrees, thereby accomplishing 'the purpose intended. It should also be noted that during the movement of the Shifters they rock and slide on the fulcra in varying relative amounts, dependent on the degrees of their angularity with respect to the line of movement o-f their pivots. The curves through which the upper ends of the Shifters rock are secondary conchoids as indicated at @fand 143 of Fig. 3, and the Shifters are thus peculiarlyadapted to operate in the manner desired. If a. bar is in 'mitted by the open construction of the cool'- ing rack or frame-work 12. After having passed over the cooling-bed, as shown, the bar is deposited on the delivery rollers 32 and in the delivery trough 31, whereby it may be transported to a shears,s'torehquse, loading-platform, and thence to cars, or otherwiseas may be desired.

From the .foregoing it will be understood that my cooling-bed and apparatus is so Y arranged and adapted that it will take bars from rolling mills and mechanically. trans-` I fer them to a shears or elsewhere, the barsv beingcooled as they pass across the bed and lso maintained straight during this trans- Although in the drawings forming partof this specification, my cooling-bed is Shown l as horizontal, I wish it understood that it may also be inclined either upwardly or downwardly, as desired. 1 Y.

The receiving trough of'my apparatus is comparatively narrow and provided with sides and the receiving rollers are similarly narrow and provided with flanges at the end of Same, all for the purpose of maintaining the bars straight as they are delivered from the rolls, and the frictional cont-act of the receiving rollers 9 on the lower Surface of the bars Serves to transfer them Fugitudinally without buckling or ltinking, as might be the case where no rollers are provided. -I also wish it understood that the Supporting racks of my cooling-beds may be spaced nearer together or farther apart. as may be desired or necessary to accommodate bars of different diameters, sections or temperature, and the apparatus is adapted to operate upon bars of any, lengths. It should also be noted that the Shifters of my apparatus are spaced close enough together so that they pick up a hot bar without buckling and they are also adapted to pick up and transfer bars from the delivery rolls to the notches of 'the receiving table, even though the bar should be moving, and the frictional contact of the bar with eacli shifter serves as a brake to stop it graduallyv without deformation.A l

The notches or hollows formed integrally in the bar 12 may be 'made of any of .theshapesvilhistrated on the left=hand portion of Fig. 6, and' I-also may use removable Spacers or .separators-made and arranged in any of the forms illustratedv on the rightlhand portiolf of F 6I The forms of sepa.-

rators shown'on the righthand portion of Fig. 6 can be made so that they can be removed and replaced when necessary on account of wear or breakage. Alternate ones may also be omitted or removed to give greater distances, longitudinally of thegfsiun ports', between the hollows notches formed thereby, in ordery to accommodate bars of different sizes or shapes, but to, dofthis the shifter'levers 17 and the amplitudel of their rocking should be adjusted, as will be readily understood. j

Although AI have Shown and described 'my improvements in considerabledetail, I do not wish to be limited to the enact and speci?` fic details shown and described, butmay use such substitiitions, modifications or lequivalents thereof, as are embraced within the Scope of my invention, as pointed out in the claims.
