[o altwhom it may concern:

Be it known that L'lhcnAnn H. S'rnvENs, of Munhall, Allegheny county, Pennsyl Vania, have invented a new and useful Improvement in Drag-Outs for Hotbeds, of which the following is a full, clear, and exact description reterenee being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a sectional side elevation partly broken away showing the hot bed equipped with apparatus constructed in accordance with my invention; Fig. 9. is a top plan view of the same; Fig. 3 is a detail side elevation on a larger scale of the receiving end of the hot bed showing the ditierent positions assumed by the drag out on the hot bed in turning materials while moving across the top of the hot bed; Fig. i is a detail side elevation of the drag out of my invention howing the swing arm thrown into its inoperative position; Fig. 5

is a detail side elevation of the drag out showing the pivoted dog and swinging arm in their extreme upper and lower positions relative to the top of the hot bed; Fig. 0 is a plan and Fig. 7 a rear end elevation ofthe apparatus shown in Fig. 5. Fig. 8 is a side elevation of one ofthe guide. rails employed for turning the work.

My invention relates to mechanism employcd in shifting rolled metal shapes laterally from the delivery table across the skids forming the hot bed or similar place of storage and it more particularly relates to apparatus for transferring rolled metal shapes having one trai'isverse dimension "greater than the other, such as l-beams and channels.

Hereto'fore with such devices, the beams 01 other materials have been shifted laterally from the roller delivery table and have been moved across the skids of the hot bed 4 without turning such shapes, in which case,

.the center line through the web and flanges of the shape is 111 a horizontal plane. In other cases the beamsare delivered length- \vise from the rolls of a rolling mill or other source or supply onto the.- delivery-roller table until opposite the hot bed, when they are first. turned until theeenter line through the web and flanges of the shape is in a. vertical plane. 1 The shapes are then shifted aterally eross the top of the skidsfor ning the hot bed in the usual manner, by means of the transfer mechanism. In such cases, either the shapes are not turned or they are turned by a separate operation, the moving of the materials laterally on the skids being interrupted or suspended until the turning operation has been completed.

The object of my invention is to provide in proved mechanism for transferring rolled metal shapes from the rollers of the delivery table to the skids of the hot bed and for storing such materials in such manner as will very greatly increase the capacity of the hot bed.

Another object of the invention is to provide improved means by which the shapes are antomatieally turned .without interruption of the shifting operation and to provide apparatus which when desired, can easily and quickly be changed so as to trans fer materials from the roller table across the' hot bed without turning the materials.

The invention consists in an improved drag-(nit having means for shifting rolled metal shapes from the roller delivery table across the skids of the hot bed and for automatically turning such shapes so as to de liver the shapes to any point in the width of the hot bed with the center lineof the shape at rightangles to that in which it is de livered in front of the hot bed by the delivery roller table.

In the drawings 2 represents the feed roll.- ers of a delivery roller table on which the materials being handled are delivered from the rolls of the rolling mill, and tithe skids forming; in thiscasethe hotbed to which the materials are trans: :rred sidcwise from the rollers 2. As shown, the rollers 2 are located at a higher elevation than the horizontal portion of the hot bed, the ends 3 of the skids lacing inclined upwardly to the elevation of the top of the rollers 2. Rollers l on the opposite side oftho hot bed are provided for the purpose of tnmsterring materials lengtlr wise from the hot bed. The feed rollers 2 are driven by means of spur gearing inthe usual manner.

Located at. suitable inter ails in the length of the hot bed below the level of the skids 3 are horizontally extending track rails or ways 5 on which the drag-outs are mounted and they are -(-onueeted by flexible connections t: with the winding drums 7 and tighteningpulleys 8 located at opposite sides of the hot bed. The winding drums are conwith any suitablet ype of driving motor,

- 'lhe carriers 9 forming part of the drag-out connections t; with tilting dog .12.

mechanisi'n are provided with shoes 10 which are mounted on the track rails 5 located below the skids of the hot bed. frame 11 is'lnovably mounted in the carrier J and its frame is connected by the flexible the winding drum 7 by which the drag-outs are caused'to move back and forth across the width of the hot bed. livotally mounted on the arrier t) is a The frame l l is provided with theprojectiolf 13 which engages with thedog 12 to depress the dog and bring its upper end below the level of the top of the skids}. Also pivotally nounted on the carrier t) is a swinging arm 14 having a projecting-lug or foot 15 on 'its lower end. The lower cnd'of the arm is also provided A shiftingv with anti friction rollers 16 whichtravel upon inclined track rails or waysl'? located at the receiving endof the .hot bed above the skids of the hot bed.

that the carrier rest upon the flange The rope driving wheel' carrier track rails 5. The arm 14 is arranged to be'swungback so as to be out of engagement with'the materials while they are being transierii'ed across the hot bed, when such materials do not require turning from the position in which they are delivered on the roller delivery table, the arm in this. position being-shown in Fig. 4.

In the operation of 'my improved appara' tus, the beams'or channels are deli'vered lengthwise on the rollers 2 of thefdelivery table until they are opposite the hot bed. 7 is then actuated and throu h the endless rope (i the carrier 9 is move across the width of the hot bed. As the tension is put upon the rope 6, the frame Y11 and the projection 13 are shifted on the carrier .9 so as to permit the dog 12 to assume. its vertical position as shown by full linesin Fig. 5. As the carrier is moved, the .dog' 12 contacts with and moves the shape on the-rollers of {the delivery table,

across the width of the rollers, and on to the As he shape'isnioved forward it slides downwardly on the inclined portion 3 of the skids 3 until ,its weight rests uponthe swinging arm H and projectin'g foot 15 on the drag-out. It will be seen .9 travels in a horizontal plane at all times while the arm 14 is tilted y means of the inclined track rails 17 on which the rollers 16 on the lower end of these arms travel. As the carrier 9 is moved forwardlyl the arm 1%; is gradually from the substantial horizontal I po I until it is i'na vertical position, this aet'on causin the beams which have beenresting upon die flange edges (f the hot bed. When-the-earrier 9 reaches the horizontal portion has been turned through an angle of 90 the; roller table to the skids forming of the, skids, the beam' degrees, and it is then pushed forwardly on the skids until it is in the desired Location onthe hot bed. The carrier 9 is then retractcd by reversing the direction of rotation of the rope driving drum 7. When the movement of the carrier is I'OYCI'SOtl, the sliding frame 1.1 is shifted relatively to the carrier in which it ismounted and the projection 13 on the upper end of the carrier engages with the lower depending end of the dog 12 and depresses the top of the. dog until it is below the level of the top of the skids 3 on the hot bed as is shown by dotted lines in Fig. 5. The carrier 2) is moved across the width of the hot bed, until it is again in position to engage with another beam, which in the meantime has been delivered into position opposite the hot bed on the rollers 2 of the delivery table, above described operation is again repeated.

\Vhen transferring materials, such as angles or other shapes which do not require turning, the arm 14 is turned back into the positionsho'wn in Fig. 4, so as to place it in its inoperative position. The pivoted dog 1 in this case operating as beforeto. transfer the materials from the roller table and across the top ofthe hot bed.

The advantages of my invention will be apparent to those'skilled ,in the art. The materials are removed from the roller delivery table to the hot bed and when desired,

are automatically turned so as to bring their smallest v dimension in a horizontal plane, in this way reducing the space occupie by the shape on the hot bed and very largely "increasing its capacity. Instead of performingthe turning operation separately from the shifting operation, the materials are antomatically turned while being transferred laterally without interruption of the shifting operation, in this way reducing the time necessary to transfer the materials to the hot bed. By means of the shifting frame on the carrier, the tiltin r dog is depressed so as to be below the 'leve' of the top of the skids when the carrier is being returned into position to again engage with another shape, and in this way the material is not brought forcibly into contact. with the comparatively thinedges of the flanges of the shapes, damage to the shapes from such contact is avoided.

The apparatus is simple and easily kept in repair.
