This invention relates to a metal carrier such as is used forY transporting fiat metal bars, tubes, rods and the like about a mill, as for example from rolling or drawing machines to annealing furnaces 'or any other-v they are lowered by craneonto sheet steelY pans which are pulled intovand through the annealing furnaces,'the pans, carriers and metal being equally subjected to the heat in the furnace. After leaving the furnace the hot metal bars,'tubes, rods and the like, with the carriers are lifted from the pan by crane and immersed in the coolingtankand then returned'to the rolling or drawing machine.

It is, therefore, an obj ect of this invention to provide an improved constructionv of carrier which will have the requisite strength Y and rigidity so thatthey will not crush or deform under heavy loads when hot.

It is also an object of the invention to provide a carrier which is ofsuflicient width to stand alone and facilitate loading atthe machine, and of such weight that they may be easily positioned by hand.`

Itis another object of the invention to provide an improved construction of carrier which will have great strength and stiffness in proportion to the amount of metal in and, therefore, the weight of the carrier.

With the foregoing and other objects in view, the invention consists in certain novel features of construction, combinations and arrangements of parts as will be more fully disclosed in connection with the accompanying drawing. d y

In this drawing Fig. 1 is a sideelevation of a carrier involvingk my improved construction showing how it is used for carrying metal tubes, bars or the like. Y y

Fig. 2 is an end view thereof.

Fig. 6 is ya transverse section of the base portion of a completed carrier. l l Fig. 7 is a transverse section of a metal plate which may be used in place of the pipe as the enclosing casing, and y f Fig is a transverse section of the base portion of` a completed carrier applying the member of Fig. y v

As indicated above, these carriers are intended to be used in pairs fortransporting metalv bars, tubes, rods or the like from the `rolling or drawingy machines, and'therefore,

must be capable of withstanding rough usage and must have the requisite strength to carry relatively heavy loads even When hot. The carrier at present in common use comprises a flat or rectangular strip of metal bent to substantially U-shape, and is the best constructionhitherto devised, but it is very far from satisfactory because of its liability to bend and to break Aafter repeated straightening.

The construction shown in Figs. 1 to 6 comprises ametal rod 10 bent into an elongated loop,'the first shape being indicated by the'V together', although it isnot absolutely necesf, sary that theyy be secured together and thisy joint may be located at other positions in the loop. The nextfoperation in forming the carrier is to take a standard or other pipe 13 as shown in Fig. 4 of the desired length and flat-ten it to substantially the shape lshown in Fig. 5.Y ,This flattened pipe is then slipped over the elongated loop formed by the rod 10 with the spaced side bars 14 thereof in substantially'the position'shown in Fig. 5 and with both ends of the loop indicated in dot and dash lines 11 projecting from the opposite ends of the enclosingcasing 13 as shown in Fig. 3.-y

draws the casing tightly about the bars 14 making a rigid construction, and these compressed portions 18 extend suiiiciently between the bars 14 to effectively and rigidly hold them in the proper spaced relation. The projecting end portions are then heated and compressed somewhat longitudinally so as to spread the loop somewhat as shown in dot-ted lines 15 of Fig. 3 at their free ends. These looped ends are then bent upwardly to a position'` indicated at 16,in Fig.l 1 forming upright looped ends to receive hooks 17 from a suitable crane or other carrying device.

` It will be evidenty from this construction that the base portion between the upright loop portions 16 is retained at the proper width so that the carrier will readily stand along on the floor at the rolling or drawing machines torpermit easy loading, and also the enclosing casing member and side bars 14 Cooperate with each other to provide a central or basey portion which is very strong and rigidV and .willl carry heavy loads of bars, rods, tubes or the like, a portion of which is indicated at 9, without bending or deforming even. when hot.

plateor strip is used. After the rod has v2O in Fig. 8. This produces substantially other `carrier construction heretofore devised,

' ation.

Figs. 7 and 8 show a slightly different construction of the enclosingcasing member for the central or base portion. In this form instead ofusing afcontinuous pipe, a metal been bent into the elongated loop, the opposite end portions spread somewhat as indicated at in Fig. 3 and then bent upwardly A to the position 16as shown in Fig. 1, the plate 19 isformed to substantially the shape shown in Fig. 7 and is then wrapped around the side` bars 14, of theecentral or base portion as indicated in Fig. 8, and then, the abutting edges of the plate are welded as indicated at the same structure as shown in Figs. 1 to 6. If preferred, the plate 19 may be wrapped around and placed in position on the side bars vof the loop before the end portions are widened or bent to the upright position.v

It has been found that the above construction providesl a carrier which is much stronger and less likely to be deformed or bent out of shape under heavy loads than any and particularly is this true when the carrier 1s heated, as it must be when passed through the annealing furnace with the rods, bars orV l tubes tobe annealed. rier suliciently light in weight to be prop-` It also provides a carerly positioned by `hand at` the machines where they are to be loaded, and the basev portions are of sufficient width so that 'they` will readily stand alone during the loading oper- They are also much stronger and much .more rigid in proportion to the metal used than is the old type of carrier.

Having thusset forth the nature of my ini Ventron, what I claim is `and an enclosing` member embracing the base portion and depressed somewhat between the sides of the loop to retain them in spaced relation.

4. A metal carrier comprising a metal bar in the form of an elongated loop having spaced side members, the opposite end portions being extendedV upwardly to form upright looped ends and a cent-ral base portion connecting them, and an enclosingr member embracing the two sides of the base portion and depressed somewhat between them to retain them in spaced relation. g
