DEVICE Fon TILTING RAILS.

Application filed March 21, A1921. i Serial No. 454,110. j

As is well known in the art of' making steel Vrails for 'railway tracks and the like, the hot rails leaving the rolls are usually carried to a hot bed by a roller line on which they lie insuccession longitudinally on their sides, and at the hot bed they are pushed or moved laterally by a sliding action to the surface of the .adjacent hot bed, still lying on their For various reasons, including convenience of handling, it islater necessary to turn them from their side position t0 an upright position on the hot vbed' such as they occupy in use. The present invention residesin means for removing in lsuccession each raiLVas it comes to position opposite the hot bed, from the roller line to the hot bed, and for automatically turning each rail on its longitudinal axis from its side position to an upright position on the hot bed during and-by this movement. The novel i features of the invention will more fully appear from the following description and claims,l taken with the drawings.

Figui-e4 is a: perspective view of aportion of a modied formof stop used in turn.- ing the rail.l l

As showny in Figures 1. and`2, a. roller line 10 made up of spaced parallelA cylindrical rollersv 11 operates as a conveyor to bring rails from the rolls to the hot. bed 12 arranged closely adjacent thereto" at one "side, and'V preferably at a slightly `lower levehthe adjacent ends of therollers being. slightly conical to facilitate the removalof the rails laterallyV from the roller line to the hot bed. The rail 13 normally lies; oli-the.` rollers kon its side, as illustrated in. Figures 1 and 2. The hot bed 12 is made up ofparallelsteel railsla` spacedJ apartcandncarrie-d by suitable supportsas-iswellknown.` 1 I The mechanismV for movingA the-hot rails in succession. from the` roller linevr 10i to., the

.hot bed, andxturning` them to uprightposition, embodies, inthe particular formvof the invention illustrated, a shaft 21 mounted to turn in bearings in the xed supports 22 on the outer side of the roller line and parallel thereto, and'having secured thereto at intervals grooved wheels or rolls 23 over which the cables 24, which are preferably made of wire, pass and by which they are reciprocated. Any known. and suitable means is used for driving the shaft and grooved rolls K therefrom slightly below the surface of the roller lineland hot bed, and they are there secured to the ends of cables 24 by suitable means such as a socket and pivotpin 27. lThe drag bar 25 has on its other side opposite4 the brackets 26 similar brackets 28 extending slightly below the surface ofthe roller line and. hot bed, and cables 29' are secu-red` to them andextend at right angles to the drag bar alongv the. hot bed slightly below the-surface, and constitute in effect continuations of cables 211. The cables and brackets Vare of course arranged between rollers of the roller line 10 and between rails .14' of the hot bed. Secured to the drag bar 25 at intervals on the side facing the hot bed,l there are projecting brackets 30 having outer rail 4engaging surfaces ycurved on .a vertical plane from a point 31 below the surface of the hot bed, inwardly towards the drag bar, and upwardlyand then forwardly at the top. on av gradually increasing .curve. rIhese` bracketsmay be inthe form of. vertical'v plates secured at their rear'straight edges to drag bar 25 byangle bars 32.v The lower portions of these cur-ved' brackets normally engage the lower edge-of the top partof the rail- 13. lying on the roller? line and Vwhen the drag bar and these brackets are moved laterally' by` the action ofthe cables across the. roller line.v and alonga part ofthe hot bed,. the` contact of the. brackets.- with the rail` cause. it; to slide laterally overthe surfacev` without vturning onits longitudinal axis fronr its-side position.' In orderTY toturn the rail on its-longitudinal axis and to bring it intoupright position. with itswearing surface` uppermost readv forconvenient han; dling, stops 3B are p aced at intervals in a line across the hot bed parallel to the roller line and at a short distance. from it. rIhese stops may be in the form of short angle bars having a vertical flange 34 extending transversely of the line of movement of the rails and projecting slightly above the surface of the hot bed in the path of the rails, and a horizontal flange 35 bolted to a fixed support 36 as shown in Figure 3. As an alternative, a short angle bar 37, having one flange wider than the other, may be pivotally mounted at the angle on the fixed support 38 by means of a pivot rod 39, with the narrow flange l0 resting on top of the support, and the wider flange ll projecting vertically slightly above the hot bed surface. The angle bar may turn on its pivot in one direction, carrying the wider flange to horizontal position and the narrower flange to vertical position, but when this is done it no longer acts as a stop, since the narrower flange is not sufficiently wide to project above the hot bed surface. Vf hen the wider flange is vertical, the narrower flange is on the side opposite to the roller line, resting on the support so that the projecting portion of the wider flange will act as an unyielding stop for a rail moving from the roller line, but may be turned down by pressure from the opposite direction. It will be understood that there are a number of these pivoted angle bar stops secured to the pivot rod 39 n so that the operator may byturning that rod bring them into or out of operative position. This serves a useful purpose when it is desired that a rail pass without turning. It will of course be understood that the drag bar is so formed and mounted as to pass over these stops' without striking them. The cooperative action of these fixed Vstops and "the curved brackets in turning the rail from side position to upright position is shown inFigure 3 diagrammatically. As here shown, when the drag bar and brackets have movedthe rail 13 far enough to bring its lower flanged edge in contact with the projecting edge 34 of the stop 33, that edge of the rail will cease to move forward; and further forward movement of brackets 30 will cause the opposite edge of the rail in contact with its inclined surface to slide or ride up that surface, turning the rail on its longitudinal axis by a rolling motion over the stop 34, one intermediate position of the parts during4 this action being shown in dotted lines in Figure 3. This figure also shows the position of the parts in dotted linesv after the rolling action is completed and the rail is in upright position beyond the stops. It will be seen that this rolling action, bringing the rail to upright position, takes place automatically as itA is being moved by one lcontinuous operation to the point on the hot bed desired. As heretofore indicated, the operator has control of the it will be understood that in its broader aspects the invention is not limited to the specific means shown, covering the various movements and actions described producing the results stated.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:

l. In an apparatus for handling rails, the combination with a rail conveyor, of a laterally extending support for rails at one sideA of said conveyor, the surface of which isv in the same horizontal plane as that of the convve or means for movin@ a rail laterall 'from' said conveyor to position on said support, stop means carried by the support for interrupting lateral movement ofv a rail thereon without interrupting the movement of the first mentioned means, and means whereby the rail moving means may tilt a rail into upright position about theY stop means.
